Description

The invention relates to the cold working of metals by pressure and can be used for stacking parts with holes, for example, stator plates or rotor plates.

The aim of the invention is to increase the productivity of the stacking process.

FIG. 1 shows a device for stacking parts with holes at the time of stacking; in fig. 2 - the same, at the moment of changing the cassette; in fig. 3 shows section A-A in FIG. one; in fig. 4 shows a section BB in FIG. 2

The device comprises a plate 1 with a longitudinal groove 2, a gate 3, a bearing clamp 4, an axis 5 on which a double-arm lever 6 is installed, a limiting stop 7 for fixing the double-arm lever 6, springs 8, a limiting stop 9, a rammer 10, a lock 11 sec. a longitudinal slot 12. Cassettes made in the form of V-shaped brackets 13.

Shiber 3, rammer 10 and gate I are in the form of plates mounted to move one relative to another.

The bolt II together with the bracket 13 is mixed under the axis of the stamp. The rammer 10 from the side of the lever has a bevel 14 under 45 °, in contact with the bevels of the lock 4 and the lever b, as well as with the base of the bracket 13.

A plate 15 is installed and fixed on the plate 1, on which the magazine 16 with brackets 13 and a punch 17 controlling the width of the brackets is fixedly mounted on the bottom side.

The rammer 10, on the side opposite to the lever, has a fixedly mounted stop .18 through which the special device transmits from the press (not shown) reciprocating horizontal movements. In order to provide simultaneous movement of the gate and rammer, a mechanism is provided consisting of a cylindrical spring-loaded pin 19, in which the head 20 on the side of the gate has a bevel. The finger has cylindrical surfaces 21 and 22. The surface 21 of the fingers, matching the hole 23 in the gate and the hole 24 in the rammer, ensures their joint translational movement together with the speed 13 and the bolt 11. The stop of the gate with the bracket and bolt is carried out with the aid of a speeding stop 25, and the autonomous movement of the rammer is carried out with the aid of a slot 26. The device also comprises a press table 27. pushers 28 and a die 29.

The device works as follows.

Replaceable staples are placed in magazine 16 with a constantly operating pressure against gate 3 (not shown). Gate 3 with locking device 4 and lever 6, which is in a vertical position with the help of an emphasis 7 and a spring 8. grips the bracket 13 for feeding it to the axis

stam. The gate with the bracket and the expander of the bracket to the matrix is fed (the lamp is carried out using a mechanism providing reciprocating horizontal movement (not shown). After the bracket installed on the gate, when it moves, it closes with the bolt 11, the stop 7 rests on the edge of the slit 12 of the shutter and the latter begins its movement together with the gate and clamped between them.

When the axes of the caliper and punch coincide, the movement of the gate with the clamp and bolt is stopped by means of a beveled stop 25, which, having entered the cross head 20 of the finger 19, axially moves the finger with the cylindrical surface 21 from the hole 24 in the scooter and inserts the cylindrical surface 22 into the slot 26 of the puller , thanks to which the rammer without the gate and the shutter continues its movement and, having contacted its oblique side with the bracket, sends the bracket in a vertical direction along the axis of the shaft verm x to the matrix. After the bracket is addressed to the die, stamping of individual parts begins with their stacking on the bracket, at the ends of which gages are made that prevent parts from jumping off the bracket. This effect is further enhanced by the fact that the distance between the ends of the bracket, determined by the control punch 17, and the distances between the base holes of the stamped part, therefore, when stacked, the parts are mounted on the bracket with a tensioner. The cut part from the die matrix is pushed onto the bracket by pushers 28 installed in the die punch. The mechanism for reciprocating horizontal movement is kinematically associated with a counting device (not shown), which gives a command to reverse the continuous stacking device after cutting the last / part of the bag. The punch then rises, and the device begins its movement in the opposite direction. Initially, the rammer 10 receives movement from the stop 18, and then, together with the rammer, it receives movement and a gate with a finger 19, which, when exiting the slot 26 while moving the rammer and resting against the edge of the hole 24, provides this movement. At this moment, the lower arm of the lever 6 is released from the rammer's bevel, and its upper shoulder rests on the bracket 13 and, when it moves together with psbro.m, the bracket rotates the lever 6 clockwise at an angle of 45 ° up to the stop 9, stretching the spring 8. Then the gate, continuing its movement, with the lever 6 lifts the bracket upwards, and the device emerges from the failure hole in the plate ensuring that the packaged and bonded package falls out.

At the moment the package of parts falls, the shutter, not the income to the magazine, stops, the gate with latch 4 and lever 6, which are in a vertical position with the help of spring 8 and abutment 7, stops against magazine 16, and the extremely removable clip 13 sinks between the latch and lever. The cycle is repeated.
