Servo-Elec­tric Press-In Tech­no­logy for Perfect Connections

Press-in Tech­ni­que

Press-In Tech­no­logy by DSM

DSM offers servo-elec­tric press-in units for a wide range of appli­ca­ti­ons — from sensi­tive proces­ses start­ing at 50 N up to powerful press-in opera­ti­ons with forces up to 120,000 N. Depen­ding on the requi­re­ment, the units are equip­ped with exten­ded stroke, elec­tro­me­cha­ni­cal brake, or backstop.

Thanks to in-house deve­lo­p­ment and manu­fac­tu­ring, indi­vi­dual adapt­a­ti­ons are always possi­ble — both mecha­ni­cally and in terms of control technology.

Stroke measu­re­ment can be perfor­med either rela­tively or abso­lut­ely, with the appro­priate measu­re­ment method flexi­bly defi­ned via the control system.

DSM provi­des three series in the field of press-in tech­no­logy, each with gradua­ted perfor­mance levels and functionality:

XMP series
QMP series
SMP series

Basic Prin­ci­ples of Joining Technology

The servo-elec­tric press-in tech­no­logy by DSM Mess­tech­nik is available in three product series: XMP, QMP, and SMP.

They are parti­cu­larly used for press-in compon­ents in steel cons­truc­tion, aircraft cons­truc­tion, auto­mo­tive and civil engineering.

Joining — A Simpli­fied Definition

Accor­ding to DIN ISO 857–1 joining is defi­ned as follows:

Joining refers to the process of connec­ting or combi­ning two or more sepa­rate compon­ents to create a unified struc­ture or system.

During this process cohe­sion is crea­ted locally and increased as a whole.

Simply put joining is the perma­nent connec­tion of two or more work­pie­ces with each other through screws, rivets or bolts.

Joining tech­no­logy also includes fusion with the help of shape­l­ess mate­ri­als, for exam­ple by using an adhesive.

This results in a connec­tion between work­pie­ces that can be both rigid and movable.

Joining Methods

The DIN 8593 stan­dard includes a cate­go­riza­tion of joining and joining tech­no­logy, respec­tively into various methods.

These are:

  • Putting toge­ther
  • Filling
  • Pres­sing on/in
  • Shape­l­ess forming
  • Forming
  • Welding
  • Sold­e­ring
  • Bonding
  • Textile joining

The follo­wing table provi­des an over­view of the indi­vi­dual joining methods and their appli­ca­tion fields:

Joining MethodDefi­ni­tionField of Application
Putting toge­therJoining, placing, setting, inser­ting, fitting toge­ther, hanging, hooking, alig­ning, partial spre­a­ding of two workpieces.Assem­bly
FillingFilling of voids or contai­ners with shape­l­ess materials.Impreg­na­tion
Pres­sing on/inElas­tic defor­ma­tion of work­pie­ces through screws, clamps, clips, press connec­tions, nailing, wedging, tensioning.Elec­tri­cal engi­nee­ring, mecha­ni­cal engineering
Shape­l­ess formingConnec­ting work­pie­ces with an addi­tio­nal work­piece or shape­l­ess material.3D-prin­ting

WeldingJoining work­pie­ces through heat/force with/without filler metal (shiel­ding gas, welding powder, fluxes, pastes)Auto­mo­tive indus­try, mecha­ni­cal engi­nee­ring, steel and metal construction

DSM Press-In Technology

All press-in units by DSM are desi­gned for the press-in methods of pres­sing on/in as well as forming.

Appli­ca­tion field

Precis­ion press-in, press-in to a stop, rive­ting, bending, embossing/forming, testing/measuring, caul­king, clip­ping, checking switch/latch points and calibrating.

The DSM press-in tech­no­logy series covers the follo­wing compres­sive and tensile forces:

  • XMP-Series: 0.5 kN bis 100 kN
  • QMP-Series: 2.5 kN bis 120 kN
  • SMP-Series: 0.25 kN bis 70 kN (only compres­sive forces)
DSM Press-In Technology Series

Elec­tro­me­cha­ni­cal Press-In Units from 0.5 kN to 100 kN

The XMP Series

The DSM XMP Series charac­te­ri­zed above all by its modu­lar design, which ensu­res excep­tio­nal flexibility.

The inte­gra­ted gear­box module, a varia­ble high-precis­ion force trans­du­cer, an abso­lute stroke measu­ring system, a large light field, and the Multi­Pro 3G control system toge­ther provide a flexi­ble solu­tion for both simple and complex assem­bly tasks. In combi­na­tion with the Multi­Pro 3G, the system also enables high assem­bly accu­racy and complete docu­men­ta­tion of produc­tion data.

A brushl­ess, elec­tro­ni­cally control­led servo motor drives the XMP press-in unit. Thanks to the modu­lar design, addi­tio­nal opti­ons such as a motor holding brake (MB), a back­stop (RS), and a holding brake (HB) can also be integrated.

Forces

The XMP press-in tech­no­logy is desi­gned for compres­sive forces as well as combi­ned compres­sive and tensile forces. The inte­gra­ted force sensor is available in various measu­re­ment ranges and can optio­nally be confi­gu­red redun­dantly.

DSM XMP Series

Elec­tro­me­cha­ni­cal Press-In Units from 2.5 kN to 120 kN

The QMP Series

The DSM QMP Series is charac­te­ri­zed by its compact design, inte­gra­ted force sensor, plun­ger, abso­lute stroke measu­re­ment system, and built-in LED status indicator.

In combi­na­tion with the Multi­Pro 3G control system, it ensu­res high assem­bly accu­racy and seam­less docu­men­ta­tion of produc­tion data.

The press-in unit is powered by a brushl­ess, elec­tro­ni­cally control­led servo motor.

Forces

All QMP press-in units are available in compres­sion, tension, or combi­ned compres­sion and tension configurations.

DSM QMP Series

Elec­tro­me­cha­ni­cal Press-In Units from 0.25 kN to 70 kN

The SMP Series

The DSM SMP Series is charac­te­ri­zed by a robust, low-main­ten­ance design, a digi­tal force sensor, and an abso­lute stroke measu­re­ment system.

In combi­na­tion with the Multi­Pro 3G control system, it enables high assem­bly precis­ion and seam­less docu­men­ta­tion of process data.

Units in this series are powered by a brushl­ess, elec­tro­ni­cally control­led servo motor moun­ted at a 90° angle for a more compact integration.

Forces

All SMP press-in units are exclu­si­vely desi­gned for compres­sive forces.
