Abstract

The invention relates to the processing of metals by pressure, in particular to a device for stamping parts from piece blanks. The aim of the invention is the expansion of technological capabilities by ensuring the stamping of parts of complex shape and increased reliability. The clamshell shifts, the clamping jaws grab the blanks and move with the rulers in the feed direction. A sleeve movably mounted on a punch fixed to the press slider moves downward, acts on the clamping jaws and moves them downwards. The clamping jaws interact with bevels with the working hole of the die matrix and are oriented relative to the die. The punch, when moving downward, moves the workpiece from the clamping jaws into the die, acts on additional bevels and orients the clamping jaws relative to the pressing axis. 1 hp f-ly, 5 ill. with and with

Ke metal pressure and can be used for stamping parts of piece blanks.

The purpose of the invention is the expansion of technological capabilities by ensuring the stamping of parts of complex shape and an increase in reliability.

1 shows a device for stamping parts from piece blanks; in fig. 2 is a section A-A in FIG. 1; in fig. 3 - clamping jaws; . on figure 4 and 5, the orientation of the workpiece in the matrix.

The device contains racks 1, in which rods 3 are reciprocally moving from drive 2 of longitudinal movement. From drive 4 of transverse movement through levers 5 and 6 and strips 7 forming a parallelogram mechanism, clamps 8 are closed. On rulers 8, clamps B and B are located, consisting of base 10 and body 11, with which clamping jaws 12 are connected. Springs 13-15 clamping jaws 12 of grips B are spring loaded relative to the clamshell 8 in three mutually perpendicular the downstream directions, the arms B are made without shells 11. On the gubyas, 12 arms C are made

act with the working hole of the mold 17 and align the axes of the workpiece and the mold by floating the jaws through the base 10, the housing 1 1 and the springs 13 and 14. Next, the punch 20 moves the workpiece into the mold directly from the clamping

Q jaws 12. During the return stroke of the punch 20 and the sleeves 19, the clamshell 8 unclenches with the spring 9, the ignition jaws of the grips B release the part at position III, and the clamping lips of the grips B at position II return to the initial level under the action of the springs 15. Drive 2 moves the rods 3 and the grab bars 8 to their original position. Next cycle

0 is repeated.

Claims (1)

01. Device for stamping parts from piece, workpieces, containing another, equipped with a mold, having a die with a working hole, mounted on a press table, and a puan orienting surfaces 16, intergeneral sleep, mounted on a press slide, operating with a mold 17, and a scraper mechanism made in cG, forming additional surfaces 18. Moving clamping jaws 12 to the mold 17 is performed by a sleeve 19, sliding on poins40 the form of grab rulers arranged symmetrically with respect to the axis of movement of the workpieces and installed with the possibility of movement from the drives in the direction perpendicular to the direction of movement of the workpieces, and in the direction parallel to the movement of the workpieces and clamping well 20. The device works as follows. At position I is a blank, on position II - pressed out after 45 sponges mounted on grab processing in the mold 17 detail. The clamshell 8 from the actuator 4 through the levers 5 and 6 and the strips 7 are shifted, and the clamping jaws 12 of the claws C clamp the workpiece, and the jaws of the clamps B - the part. The clamshell 8 together with the rods 3 move from the actuator 2 to the stroke of the clamshell device, transfer the workpiece to position II, and the part to the unloading position III, Sleeve 19 with the working stroke of the punch 20 moves the clamping jaws 12 of the grips B to the mold 17, wherein sleep, mounted on the press ram, grab mechanism, made in the form of grab rulers arranged symmetrically with respect to the axis of movement of the workpieces and installed with the possibility of movement from the drives in the direction perpendicular to the direction of movement of the workpieces, and in the direction parallel to the movement of the workpieces and clamping rulers can be moved vertically and in two mutually perpendicular horizontal directions and spring-loaded in these lines. These are characterized in that, in order to expand technological capabilities by providing stamping of complex-shaped parts and increasing reliability of operation, it is equipped with a mechanism for moving the clamping jaws in the vertical direction, made in the form of a sleeve mounted on the punch with the ability to move in the vertical 31368089 and interacting with capture n m On the outer sides of the clamping jaws, from the side of the die, bevels are made with the possibility of interaction with the working hole of the die. 2, The device according to claim 1, about tl and, of course, by the fact that additional bevels are made on the inner lateral sides of the clamping jaws on the side of the punch box that can interact with the punch. 1 12 srigL
