Industrial presses and joining systems — TOX PRESSOTECHNIK

Force range

2.5–25 kN

Mechanism

toggle (knee-lever) — minimum operator effort for high press forces

Max. allowed handle pull force

• 50 N (KFS 002)
• 220 N (all other KF models)

Max. deflection under load

• 0.05 mm (KFS 002) up to 0.45 mm (KFLU 025)

• L (enlarged open height)
• W (enlarged throat depth) — available from 8 kN up only

Available accessories across the whole FinePress line (KF/ZF/PF/PFH): ergonomic side grip ZEH, electric counter ZEZ, return stroke lock ZR-L, travel sensor ZW, tool fixture ZA (including a screw-free "3-in-1" mount), and slide table ZHST.

Stroke measured at lever angle 90°; parenthetical values are the alternative lever position.

Force range

2.5–4 kN

Mechanism

rack and pinion — transmits the lever pull force into a constant ram force throughout the entire stroke

Max. allowed handle pull force

• 200 N (ZFS 002)
• 300 N (the 4 kN models)

Max. deflection under load

• 0.05 mm, identical across all four models, the smallest and most uniform value in the FinePress line
• max. allowed tool moment: 25 Nm

End-of-stroke adjustment

stop screw, for precise positioning

Air connections

integrated on the frame — clean plumbing

Only the S variant exists at the minimum force (PFS 002); the L variant covers the full 4.0–57.5 kN range.

Force range

8.5–57.5 kN (at 6 bar)

Mechanism

• hand-lever toggle mechanism: 54 mm approach stroke, max. 6 mm pneumatic power stroke

Complies with the EC type examination certificate. The whole FinePress line (KF/ZF/PF/PFH) is available on the UUF universal base, with load capacity up to 900 kg.

Only the L variant covers the full range; the W variant exists only at 8.5 kN.

Principle

as a general rule, the larger the point diameter, the greater the joint strength

Available diameter

• 1.5–26 mm
• special lengths available at 30, 40, 50, 80, 100 mm

Miniature variant

2 mm diameter — for component miniaturization, ideal for sheet thicknesses 0.1–1.2 mm

Combined sheet thickness covered

• 0.3–1.4 mm at Ø2 mm point
• 1.0–3.0 mm at Ø6 mm point
• 1.6–6.0 mm at Ø8 mm point
• 4.5–11.0 mm at Ø12 mm point

Sheet-pairing rule

• hard material on the punch side, soft material on the die side
• thick sheet on the punch side, thin sheet on the die side
• recommended thickness ratio: t1 (punch side) ≈ 2.5–3.0 × t2 (die side)

Joint strength, examples from TOX test tables

• DC01 + DC01, 3.00 + 2.00 mm, Ø12 point: 7,800 N shear, 6,100 N tensile, 98 kN press force
• 1.4401 + 1.4401 (stainless), 2.50 + 1.25 mm, Ø10 point: 8,500 N shear, 4,400 N tensile, 105 kN press force
• Cu + Cu, 6.00 + 5.00 mm, Ø12 point: 6,200 N shear, 4,200 N tensile, 101 kN press force
• S420MC + DC04 (sheets of different strength grades), 4.00 + 1.25 mm, Ø12 point: 10,000 N shear, 5,400 N tensile, 125 kN press force

Die body variants

• stepped — for difficult accessibility (C-profiles, U-profiles, angled sheets)
• flat — reaches tight corners, produces small seam widths

Quality verification

non-destructive, by measuring control dimension X (remaining bottom thickness), tolerance ±15%

Unlike spot welding, where durability is usually tested destructively (chisel test), a TOX joint is verified without damaging the part — only dimension X is measured. Maximum allowed tool tilt to the sheet surface: 3°, with slightly reduced joint strength beyond that. The four strength examples above are rows from a much larger TOX table of several hundred actually tested combinations, across steel, coated steel, aluminum, stainless steel, copper, and dissimilar-material combinations. For your specific combination, the exact value comes from a TOX-Test Report.

Tool durability (number of joining points), by material — from TOX's installation data sheet (scule-imbinare.pdf).

Available diameter

5, 6, 8, 10 mm

Construction

3–6 solid parts and moving segments

Recommended use

• hybrid "clinching + gluing" joining with an intermediate layer
• high flexibility across sheet thicknesses — a few standard die types cover a wide application range

Combined sheet thickness covered

• 0.4–2.5 mm at Ø6 mm point
• 0.6–5.0 mm at Ø8 mm point
• 1.0–6.0 mm at Ø10 mm point

Installation tolerance

maximum allowed tool tilt: 1° (stricter than Round Joint) — the flange must fully cover the die diameter

Even with some moving segments missing, the SKB die still produces a strong joint — process reliability is significantly increased compared to a die with only moving segments. Re-joining an already-formed point can destroy both the die and the joint.

Principle

two joints formed from one stroke of the press, using one set of tools (punch and die)

Stated goals

• improve productivity
• protect the joint against rotation (anti-twist device)
• significantly increase joint strength vs. a single point

Suited to

slim flanges and limited installation spaces

TWINpoint tools are secured against rotating by default — the flange surface, parallel to the pin/cavity axis, prevents the tool from rotating in the tool holder. Confirmed physically in TOX's accessories catalog (scule-imbinare-accesorii.pdf): types from TOX 210.180 through TOX 218.220 (punch) and TOX 210.160 through TOX 226.220 (die).

Principle

• a punch presses the sheets to be joined into a die, creating an undercut through plastic deformation
• the increased contact surface at the joining point creates numerous metallic micro-contacts — durable electrical conductivity, alongside mechanical strength

Problem solved

connections where both mechanical stability and electrical conductivity matter — battery, automotive, and electrical-component applications

Maintains conductivity

even through soft coatings (e.g. tin on copper), at just a few µm thickness, without prior stripping

Applications named by TOX

• battery cell connections
• aluminum-to-copper joining
• busbar connections
• electronic component assembly
• fuse boxes, Li-ion battery control boxes, auxiliary heaters

TOX also offers THETA® Clinching — a newer, laser-assisted technology for materials that resist conventional mechanical clinching (ultra-high-strength steels, low-ductility die-cast aluminum alloys). The equipment works with or without the laser step. Availability through Lang & Sin for the Romanian market still needs separate confirmation — it isn't part of the standard offering yet.

Force range

Combined force range

11–1,727 kN (X-S and X-K together)

X-S (slim)

• power stroke 6–22 mm
• total stroke 50–100 mm

X-K (compact)

• power stroke 6–96 mm
• total stroke up to 400 mm

Guarantee

up to 10 million strokes in 12 months

Spring

pneumatic

Applications named by TOX

clinching, riveting, setting functional elements, pressing, forming, deep drawing, embossing, punching, fine blanking, crimping, testing, mounting

The X-KT system separates the pressure intensifier (X-ES) from the working cylinder (hydraulic cylinder HZL or pneumatic cylinder X-AT), allowing longer power strokes than the integrated variant — up to 6 working cylinders per intensifier, with a TOX Hydro Split Coupling for system separation.

Selection from the full table (type-x-s-x-k.pdf) — the X-S 170 model (1,727.5 kN) is the highest force documented for any individually numbered model across the entire TOX drive lineup.

Transmission mechanism

ball screw for pressing operations, or planetary roller screw for high joining speeds and tight spaces, depending on the variant

Positioning repeatability

10 µm

Control

TOX PowerModule Core servo inverter — inflection-point detection, customizable acceleration/deceleration profiles

Applications named by TOX

pressing/compressing (including fuel cell stacks), crimping, mounting, testing/inspection, punching, fine blanking

Industries named by TOX for EXe-K

• semiconductors
• medical technology
• pharmaceuticals
• optics and display manufacturing
• food technology
• hydrogen and battery technology

A cleanroom variant is also available (EXe-K Cleanroom, same 0.1–200 kN/300 mm/s range) — relevant for customers in electronics, medical, or semiconductor manufacturing. A motor holding brake prevents the ram from dropping when power is disconnected.

De reținut: Above a certain tool weight, the ram can drift down on its own when power is disconnected unless the motor holding brake is fitted. The maximum tool weight allowed without the brake depends on the force class and is confirmed at order time, together with the configuration.

STP 03-11

direct pneumatic two-hand control, without an added safety function

STP 03-10

pneumatic two-hand safety control, compliant with EN 574 — the base variant

STE 075

for automated lines, with the cycle signal supplied by the customer

STE 317

foot pedal control — hands-free operation, requires mechanical guarding of the work area (CLX device)

STE 325 / 336

electric two-hand control — basic functions up to simple programming

STE 326 / 328

electric two-hand control with PLC — the most flexible and programmable in the range

Criterion that decides the control level

• tool opening: below 6 mm, simple pneumatic control is permitted (STP 03-11); above 6 mm, EN 574-compliant two-hand safety control (STP 03-10) or mechanical guarding of the work area is required
• level of automation: on an automated line, the cycle signal comes from the customer's system (STE 075); at a manual station it comes from buttons or a foot pedal
• sequencing needs: fixed functions are covered by STE 325 or STE 336, a programmable sequence needs the PLC in STE 326 or STE 328

All TOX-Controls units include an air servicing unit and flow-control valves. Locking function: once the cylinder enters the power stroke and the "tool closed" sensor confirms, the buttons can be released — the cylinder develops the preset pressure and retracts automatically. Safety note: on air-pressure loss, the working rod will NOT retract and could drift down slowly — relevant for tool design and operator training. All TOX-Controls units comply with the European standard EN 13736 for pneumatic presses. On electric two-hand controls, the cycle starts only if both buttons are pressed within 0.5 seconds of each other, and if one is released early, the cylinder retracts immediately. For tools with an opening above 6 mm, DIN EN 13736 requires fitting a "tool closed" sensor as a safeguard for the self-locking control, unless the work area is otherwise guarded.

Function

monitors clinching processes by measuring press force and cylinder displacement at the end of the stroke

Measuring channels

2–12, simultaneously — a single CEP unit can monitor multiple stations/tools

Interfaces

Digital I/O, EtherCAT, EtherNet/IP, Profinet

Measuring programs

64

CEP 600 automates in production exactly the "control dimension X" concept used by the TOX-Test Report described above in the Joining tools section — the test report establishes the target X value in the lab, CEP 600 verifies it automatically on every part, in-line.

Function

reads force-displacement (X/Y) data pairs from two measuring channels, compares them against configured window values or an envelope — IO/NIO message

• data export via SFTP, fieldbus, or USB (EPW 600)

EPW 500 is the monitoring unit explicitly recommended for the TOX-FinePress benchtop press line (KF/ZF/PF/PFH) — see the Benchtop presses section, where every series lists "pressing monitor connection" as an optional accessory.
