DD252332A1 - REAR STOP WITH IMPULSE TRANSDUCER - Google Patents

Abstract

Field of application of the invention is the processing or processing of metal sheets. Objects of the application are devices for separating, in particular Anschlaege of guillotine shears. The aim is to create a stop that can be used to cut strips with the required accuracy and parallelism from sheets or couls. The object is to develop a stop with which pulses are generated for driving the separating device and other auxiliary devices when reaching the strip width to be cut. At a per se known stop suspension with adjusting device for Vorfabrikatbreiten one, having a defined cross-section, profiled strip provided with reference and clamping surfaces and brackets for impulse displaced and lockable attached.

In Fig. 1, separating device 1 and the stop suspension 2 with adjusting device of a known guillotine, the semi-finished product 3, the Vorfabrikat 4 and the complementary device are shown.

2, the profile strip 5 and the laterally displaceable brackets 10 for pulse generator 20 and cable holder 27 are shown.

Fig. 3 shows a side view of the holder 10 for pulse generator 20 and the particular cross section of the profile strip 5, formed by two flat parts 6 with reference surfaces 7 and clamping surfaces 8, connected by a arranged at the reference surfaces 7 web with slots 9. Furthermore, it shows the carriage 19 with the encoder 20 mounted thereon, a compression spring 21, acted upon by pressure screw 25 bridge 26, top plate 22 and bottom plate 23 with the shoulder screws

In Figure 4, the front part 11 with stop edge 12, a pivoting part 13 with wear part 14, a rear part 15 that the slide guide 16 and a set screw 17 and clamping device 18 receives shown.

The device complements a separator and is to be mounted instead of one of the scope of delivery of this device belonging, single-acting stop on the stop suspension with adjusting device.

The use of an accessory for guillotine shears according to WP 11161 is not hindered by the device described.

If a semi-finished product 3 is inserted into the separating device 1, its front edge abuts against the wear parts 14 and moves them together with the pivoting parts 13 in the direction of the profile strip 5.

Since the pivoting parts 13 are in operative connection with the pulse generators 20, a pulse is triggered and then stopped the movement of the semi-finished product 3 by concerns of the pivoting parts 13 on the reference surfaces 7 of the profile strip 5.

The triggered pulse starts the separator 1 and other ancillary equipment, such as counter, discharge conveyor u.a.m.

After working the separator 1, the corresponding prefabricated 4 falls on a stack or conveyor, not shown.

The wear parts 14 are thereby relieved. The compression springs 21 press pivoting parts 13 in the direction of the separating device 1 until they rest against the stop edges 12 of the front parts 11, as a result of which the pulse generators 20 are also opened again. The described processes, starting from semifinished product 3, can now be repeated.

The width of the Vorfabrikates 4 is by means of known stop suspension with actuator 2 by parallel setting the

Profile strip 5 is set to the separating device 1. "

The use of the device according to the invention prevents that by incorrect insertion of the semi-finished product 3 Vorfabrikat 4 is not cut in parallel. Only when delivered by the semi-finished product 3 preferably two according to the semi-finished width on the profile strip 5 and recorded by holders 10 and protected pulse generator pulses, the separator starts. The pulse generator 20 are aligned parallel to the profiled strip 5 by slide 19, which can be moved after loosening the clamping device 18 by means of adjusting screw 17 on the slide guide 16 mounted in the rear part 15.

According to the semifinished width, the brackets 10 for pulse generator 20 on the profile strip 5 after loosening the pressure screws 25, which are in operative connection with the bridges 26, which thereby detach from the clamping surfaces 8 of the profile strip 5, are arranged. The position of the cables transmitting the pulses should then be corrected to possibly displace the cable holders 27.

Claims (2)

1. Rear stop with pulse generator for separators with per se known stop suspension and adjusting device for Vorfabrikatstreifen, characterized in that a profiled strip (5) with a defined cross section, consisting of flat parts (6) with reference and clamping surfaces (7,8), in whose Near a web with slots (9) is provided, and laterally displaceable brackets (10) for the pulse generator (20) and cable holders (27), is displaceable and lockable attached. 2. Rear stop with pulse generator for separating devices according to item!, Characterized in that the laterally displaceable holders (10), consisting of front part (11) with stop edge (12), rear part (15), upper and lower plate (22,23) , a pivoting part (13) with wearing part (14), which is in addition to a compression spring (21) in operative connection with the pulse generator (20) by adjusting screw (17) and clamping device (18) adjustable and lockable and by a guide ( 16) guided carriage (19) record and by pressure screws (25) in operative connection with bridges (26) against the profile strip (5) can be stretched. For this 2 pages drawings Field of application of the invention The field of application of the invention is the processing of semi-finished products of various types of materials. Objects of the application are devices for separating, in particular, attacks on guillotine shears. Characteristic of the known technical solutions Known technical solutions include those described in DE-AS 1752899 and DE-AS 1777102. However, these writings contain nothing to the design of the stops with pulse generator. Design and arrangement have been described in DE-OS 2432 588 for tape cutting machines. However, it is for classification in preferably guillotine shears, especially in existing, not easily transferable and according to the description they are suitable for conductive materials. Zie! the invention The aim of the invention is to provide a stop, with the help of panel η or Couls strips can be cut with the required accuracy and parallelism. The technical task The object is to develop a stop, with which when reaching the strip width to be cut pulses for driving the separator and other additional devices are generated. Features of the invention According to the invention it is proposed that a profile strip with certain cross section is attached to a known stop suspension with adjusting device for Vorfabrikatbreiten having two flat parts with reference and clamping surfaces and a web with slots, so that brackets for pulse generator, consisting of front part with stop edge, pivoting part and Wearing part which, supplemented by a compression spring, are in operative connection with the pulse generator. Rear part with slide guide, as well as adjusting screw and clamping device, the carriage for pulse generator, all held by upper and lower plate, can be blocked by bridged by pressure screws bridges, can be moved laterally. The required setting of the pulse generator to each other allows a carriage, which can be moved with dissolved clamping device by means of screw on the carriage guide. The pulse generator is protected from overload by shocks when hitting the semifinished product by a holder, wherein the wearing part in operative connection with the pivoting part which pivots upon impact of the semi-finished product on the wear part against the reference surfaces of the profile strip. When unloading a spring pushes the swivel part back against the stop edge in the front part. During the described pivoting operations, the pulse generator is actuated or opened again.
