SU1255247A1 - Arrangement for feeding elongated material to the machining zone - Google Patents

Description

The invention relates to the cold treatment of metals by pressure and can be used to supply long material to the treatment area.

The aim of the invention is to increase the reliability of operation and to expand the range of adjustment of the feed pitch,

. FIG. 1 shows a device for feeding a lengthy material into a machining zone, an incision; in Fig.2, view A in Fig.1.

The device comprises a base 2 mounted on the bottom plate 1 of the stamp with a guide groove B, in which a feed carriage is located, worn in the form of a slider 3, fitted with a spring 4, a gripping body, made in the form of a pressing plate 5, and a wedge support, wedged in Roller 6 view. Between the crawler 3 and pressure plate 5 there is a copier plate 7 with a carbon copy working surface. On the base 2 a brake carriage is fixed, made in the form of a fixed stand 8 with a spring 9 by a clamping plate 10 (gripper) with an elastic insert 11, holding the wire 12 from displacement and screwing the feed pitch adjustment mechanism screw-shaped 13 into it. Slider 3 A rod 14 is screwed in, on which a spring 5-6 is located between the column 8 and the nuts 15, spring-loaded in the wire feed direction 12 (in the direction of arrow S). A wedge 18-20 is installed in the top plate 17 of the punch to effect the wire 12 and release it from the clamp. I

The device works as follows:

The wire 12 through the straightening mechanism (not shown) and the feeder, when the clamping plate 5 is pressed out of the bar 7 with the copier working surface, is routed to the measuring size in the stamp processing zone (not shown).

Next, the upper plate 17 of the punch from the press slide (not shown), together with the wedges 18-20, is fed upwards to the initial open position.

The slider 3 under the action of the spring 16 moves along the guiding groove B until it is in contact with the screw 13

the wedge 18 is retracted upward from the roller 6. After stopping the slider 3 and retracting the wedge 18 from the roller 6, the wedge 20 acts on the right side edge of the bar 7 with the copier working surface and moves it along the guide samples in the slider 3 in the direction of wire 12 (along arrow S), allowing the pressing plate 5

under the action of the spring 4, lower and press the wire 12 to the slider 3.

When the upper plate 17 of the punch moves downward, the wedge 20 comes out of contact with the right side edge

of the strap 7 with a copier working surface, after which the iS wedge presses on the roller 6 and moves the slider 3 together with the clamped wire i 2 along the guide groove B by the amount of the feed pitch. When the top plate 17 of the punch and wedge 18 is further lowered, the slide 3 remains stationary, and the wedge 19 acts on the left side edge of the plate 7 with the copier working surface and moves it in the opposite direction of the feed, lifting the presser plate 5 with the copier working surface. Between the presser tile 5 and

wire 12 forms a gap.

When the upper plate 17 of the stamp moves upward, the wedge 19 comes out of contact with the left side edge of the bar 7 with the copier working surface, leaving it fixed. The wedge 18 rises and departs from the roller 6 and allows the slider 3 under the action of the spring 16 to move under the wire 12 in

the direction opposite to the feed until it is in contact with the screw 13. The wire 12 remains stationary and is kept from shifting under the action of the spring 9 by the pressing plate 10

with elastic insert 11 and stand 8.

After stopping the slider 3 and removing the wedge 18 from the roller 6, the wedge 20 acts on the bar 7 with a copier working surface and moves

her in the feed direction. The pressing plate 5 O. is paused by the action of the spring 4, pressing the wire 12 against the slider 3. The feeding of the wire to the treatment zone can be repeated.

To obtain an accurate feed pitch and ensure reliable operation of the device, the clamping force of the wire 12 between the pressure plate 5 and floor 3 is 12552474

Ear 3 should be more force the slider 3 to the original position of the plan - to keep it from moving between plate-7 and 7 with a copier working surface 10 with an elastic insert. And with the aid of a wedge 19 with the stand 8. This is achieved by adjusting-creating a gap between the bottom - force compressing the springs A and 9, -s wired with clamp-Dp providing free return tile 5,
