Description

(54) STAMP

one

The invention relates to the processing of metals by pressure.

A well-known stamp has a drive and contains a base with a plate installed on it, in which a revolving disk is mounted, as well as working tools, a magazine-feeder, ejectors and sliders with dogs and clamps 1 fixed on them.

The disadvantages of this machine are the low accuracy of the installation of the workpieces in the working position and the insufficient change of the working tool.

The purpose of the invention is to increase the productivity and quality of manufactured parts.

 The goal is achieved by the fact that the chip drive, having a drive and containing a base with a plate installed on it, in which a revolving disk is mounted, as well as working tools, a magazine-feeder, ejectors and sliders with dogs and clamps attached to them, is provided with an additional disk with sockets. under the workpiece, mounted on a revolving disk, as well as a supporting ring and ring gear, kinematically connected with the working tool, while the stamp is equipped with a stop ring and replaceable clips; the tools are mounted in the indicated clips, and the retaining ring is mounted in the plate under the 5 revolving disk and equipped with fingers interacting with the dog and retainers.

The stamp is provided with clamps of workpieces being processed, each of which is made in the form of a two-arm lever pivotally connected to one shoulder with a revolving disk, as well as copiers installed under the revolving disk with the ability to interact with levers and ejectors.

Working tools are equipped with elements for adjusting their position relative to interchangeable clips.

FIG. I shows the proposed stamp, top view; in fig. 2 shows a section A-A and an additional step-cut section A-A of the lower part in FIG. one; in fig. 3 shows a section BB in FIG. 2; in fig. 4 shows a section B-B in FIG. one; in fig. 5 is a schematic of the machining of a part groove by successive cutting of the lowering; in fig. 6 - scheme

iioiiopora finger thrust lower ring; in fig. 7 - workpiece; in fig. 8 a section of the G – D in FIG. 2

The reel-to-needle bridge contains a base 1I1 I with an intermediate ilite 2 installed on it, in which C) cT (j)) oiHii osnona 1 and c is mounted crawler 3, carrying the nlanks 4, spring-loaded pawl 5 and slide 6, located under the magazine nitatele.m 7. Axle 8 is placed in the intermediate plate, on which there is a bottom lower ring 9 on the bottom, carrying the fingers 10,., and on top - a revolver disk 11, in the windows of which are installed the bearing panels 12 and latches 13. To the revolving disk fixed donorrnggelny disk 14, supporting ring 15 and count frontal scaffold 16. In addition, in the revolving disk on axes 17, L-shaped levers 18, po1 “) are formed, protruding by projections of internal 19 ixpxiiocTH 19 copier 20 connected to the intermediate plate. The outer surface of the copier also has protrusions 21, which interact with the pushers 22. A working tool 23, made in the form of a milling cutter, does not rotate by means of a gear train 24 and is mounted | ) Aim in a quick-change holder 25. A working tool 26, made in the form of a fixed rectangular draw, is also installed in a quick-change holder 27. Reg.; The cutting and fastening of the tools are made by a wedge 28 and screws 29 and 30. (;; a hinge system operating from a press ram, or a pneumatic pneumatic piston ||, P1ndra (hydraulic cylinder) slider shaft is connected by an axle 31.

The stamp works as follows. 1) iodine. Press the slide or the stroke of the cylinder cylinder (and hydraulic cylinder) lever-hinge system or individual puffs .. 1no1H) of the drive (not shown) percMenuiCT on the base 1 to the right under the intermediate or second 2 slider 3 in. Place with fixed foil to it, strips 4, doggie 5 and gate 6. When this.m, the spring-loaded dog moves relative to the body of the commander 9, passes io.ii with the next finger 10 and is located to the right of it, and never () delivers from the magazine-feeder 7 into slot additional disk 14, which shifts towards the axis of the punch vyta .; 1, the 22, is located on the annular 1nstern 16 and the supporting ring 15 under the clamp 12 and the latches 13 of the turret disk 1 1. At this moment, the L-shaped lever 18 connected to the axis 17 is in its original position, the shelf is horizontal, and the rack vertically to the workpiece blank, gear transmission 24 of the working tool 23 is located in the mania with the ring non-core 16.

When releasing the press ram or moving the rod of the non-cylinder (hydraulic cylinder) to the left, the lever-hinged system or individual drive shafts moves the slider 3 in the same direction. The pawl 5 and the slats 4 moving with the slider abut against the fingers 10, turn the stop ring 9 on a given angle and fix it with high accuracy in this position. At the same time, the spike moves back to its original position, the revolving disk II through the axis 8, together with the clamps 12 and the latches 13 and L-shaped levers 18, as well as the additional disk 14 with the workpiece, the supporting ring 15 and the ring shchestrin 16 also rotate at the same given angle. At the beginning of rotation, the L-shaped lever, when subjected to a copier surface 19, rotates on axis 17 and presses on n) and 12 and the spring-loaded latches 13. The locking pins fix it along the holes in the part, and the pressure presses the part to the supporting ring 15 and the gear gear 16, which rotates the cutting tool 23 through a gear transmission 24. In the fixed and pressed position, the part is successively brought to several positions. In the case under consideration (Fig. 4

5 positions I-1U correspond to machining the part with cutters and Y, U1 - rectangular broaches. After processing, the part takes the form shown in FIG. 6. In the part removal area, the outer projections 21 of the copier 20 act on the ejector 22, which removes the part from the slot of the additional disk 14. Quick change of working tools is achieved by using quick-change holders 25 and 27, and adjustment of the working position and reliable fastening of the tool are provided with wedges 28 and screws 29 and 30.

The stamp of the proposed design allows to increase productivity and the quality of manufactured parts, in comparison with the prototype.
