(54) STAMP FOR TREATMENT OF FLAT PARTS

This invention relates to the cold working of metals by pressure.

A known stamp for machining parts contains a working tool installed on its lower plate, made in wood at least two knives symmetrically mounted on both sides of the longitudinal axis and inclined at an angle to the horizontal plane of the stamp, magazine, pusher driven in the movement in the horizontal plane from the top plate of the stamp, the slide pusher, located between the side walls of the pusher and moving parts from the store to the working position of the stamp (in the working area), ejector parts from shea Bern pusher, made in the form of a lever, hinged 20 stamped on the bottom plate of stamp However, in the known stamp of the part in the sliding pusher, the sliding pusher of the position of the stamp and the part relative to the sliding pusher during the technological operation is not fixed, which leads to insufficient precision and reliability of the stamp.

The aim of the invention is to improve the accuracy of machining parts and reliability of the stamp.

The goal is achieved by the fact that in the stamp for processing flat years, containing working tools, a magazine, a pusher driven in the horizontal plane from the drive, a slide valve located between the side walls of the pusher and moving parts, mounted on its bottom plate. from the magazine to the working position of the stamp, the ejector to remove from the sliding pusher, the sliding pusher is spring-loaded relative to the pusher in the feed direction of the parts in the side walls of the pusher three fi solid groove, the stamp is equipped with a mechanism for fixing parts in a sliding pusher, made in the form of rods in the vertical direction, bearing rollers that enter one of the figured grooves; the clamping mechanism of the parts to the sliding pusher at the working position, made in the form of a slider carrying in the vertical direction, carrying the rollers included in

another shaped groove, and a strap, spring-loaded lattice of the slider and interacting with the part; the mechanism for fixing the slide pusher on the working position, made in the form of pins that are spring-loaded in the vertical direction, interacting with the slider and with the slide pusher; A movable in the vertical on the direction of the holder, bearing rollers included in the free shaped groove, and the working tool is fixed in the holder.

In the pusher from the side of the working position of the stamp, an adjusting screw is attached, which interacts with the sliding pusher.

Figure 1 shows the proposed stamp, the overall appearance; in fig. 2 - the same plan; in fig. 3 shows a section A-A in FIG. in fig. 4 is a section BB in FIG. in fig. 5 - detail.

The stamp for machining flat parts contains a base 1 on which a slider 2 is mounted with an axis 3 connected to a drive (not shown;. The slider 2 is provided with side plates 4 between which is installed a sliding plunger 5 spring-loaded with respect to the slider 2 by springs 6. Based on 1 the plate 7 is fixed, located above the slider 2. The shop 8 is fixed on the plate 7. The plate

7 is fixed on the base 1 by means of the plate 9. The free ends of the side plates 4 are interconnected by a vertical plate 10 carrying the adjusting screw 11. In the plates

4 figured grooves 12 and 13 are made.

The 8-slide pusher 5 has a groove in which the bar 14 is installed, is spring-loaded in the vertical direction and the carrier rod 15 and the rollers 1 The rollers 16 move along the figured grooves 17 made in the plates 4.

In the slab 7, the slider 18 is mounted for vertical movement, carrying rollers 19 moving along the shaped grooves 12. In the slider 18 there are mounted guide columns 20 with nuts 21 at one end. At the other end of the guide columns, a clamp 22 is fixed. On the guide columns 20, springs 23 are installed, located between nuts 21 and a slider 18. In plate 7, spring-loaded pins 24 are also installed, which are inserted into blind holes 25, made in gate valves 5, pins 24 fix gate slide

5 in a predetermined position. Between the clamp 22 and the slider 18, as well as between the pins 24 and the slider 18, there are spacers 26 of elastic material. In the plate 7, a slider 27 (holder) is mounted for movement in a vertical direction. The slider 27 is fixed in it. On the slider 27 (holder) there are fixed rollers 29 moving along the figured grooves 13. On the upper side of the sliding pusher & a groove 30 is made open from the slider side 27 / for positioning the parts 31 j therein. Surfaces 32 and 33 of the parts 31 are subject to processing. And a window 34 is made to the base to remove the parts 1 6 the sliding pusher 5 is made behind the groove 30 through the longitudinal groove 35 to accommodate the end lever 36 (resetter), hinged in plate 7. Part 31 has holes 37.

Straps for processing flat parts works as follows.

Claims (2)

The slider 2 through the axis 3 is driven by the actuator and moves to the right, through the springs 6 acts on the slide pusher 5 and also moves it to the right. The part 31 from the magazine 8 falls into the groove 30 and moves to the right up to the stop of the surfaces 32 into the slider 27 (holder). The lever 36 (ejector) moves freely with the slide pusher 5 to the right and then assumes its original position and enters the through longitudinal groove 35. The stroke of the sliding piston 5 relative to the slide 2 is limited by the adjusting screw 11. With the further movement of the slide 2 to the right, the slide pusher 5 departs from the screw 11, compressing the spring 6. At the same time, the rollers 16, moving along the figured grooves 17, move the strips 14 with the rods 15 upwards. The rods 15 enter into the holes 37 and fix the item 31 in the groove 30 of the sliding pusher 5, and the rollers 19, moving along the figured grooves 12, move the slide 18 down. The slider 18 through the gaskets 26 acts on the pins 24, which enter the holes 25 and fix the slide pusher 5, as well as act on the clamp 22, which presses the piece 31 to the slide plunger 5. With the further movement of the slide 2 to the right, the slide pusher 5 stands on place, and the rollers 29, moving along the figured grooves 13 / move the slider 27 (clip) down. The protrusions 28 perform two-sided stripping of the part 31 over the surfaces 32 and 33. During the reverse movement of the slide 2 to the left, the slide pusher 5 is held in place by pins 24 and springs 6. Rollers 16 moving along the copier grooves 17 / lowering the bar 14 with the rods 15. The rods 15 come out of the holes 37 of the part 31. The rollers 19, moving along the copy grooves 12, move the slider 18 upwards. The clamp 22 releases the part 31, and the pins 24 under the action of their springs move upwards and out of the holes 25. The adjusting screw 11 acts on the slide pusher 5, and the slider 2 together with the slide slide 5 moves to the left. Roller 29, moving in grooves 13, moves slide 27 (holder). up, and the lever 36, moving along the groove 35, acts on the part 31 and removes it from the groove 30 of the slide gate 5. Part 31 through the window 34 is removed from the working area. Then the cycle is repeated. Claim 1.
