Abstract

The invention relates to equipment for mechanical assembly work and can be used to cut the wire into dimensional workpieces, followed by secretly pressing them into connected parts of the product, in particular for assembling powders, shadow boxes and cosmetic kits. The purpose of the invention is the expansion of the technological capabilities of the semi machine and the production of prefabricated products with a secret pressing of the axes to a certain depth. The semiautomatic device is equipped with two symmetrically positioned relative to the slot for placing the blanks by straightening, feeding and cutting mechanisms for the wire. The ball feed mechanisms are located in movable guides and sliders, reciprocating, and the joint movement of the guides and sliders causes the wire to be fed and the axes to be pushed into the coaxial holes of the parts to be connected to the depth determined by the slide stroke, and the sliders reverse to the stop pulls the wire out of the product; The wire cutting mechanism is made in the form of movable and fixed sleeve knives, which serve simultaneously as guides for the wire. 4 il. g.

Description

The invention relates to equipment for mechanical assembly work and can be used for cutting the prvoloki on dimensional workpieces, followed by secretly pressing them into the connected parts of the product, in particular for the assembly of powders, shadow boxes and cosmetic kits.

The purpose of the invention is to obtain prefabricated products with a secret pressing of the axes to a certain depth.

FIG. 1 shows a semi-automatic, top view; in fig. 2 - node I. on figure 1; Fig, 3 section aa. figure 1; in fig. 4 - pneumatic scheme of a semiautomatic device.

The semiautomatic machine for cutting and pressing in axles is provided with wire straightening mechanisms located on frame 1, located in sliders 2, which are fastened to grooves 4 and fingers 3, using grooves and pins 3, to wire guide mechanisms 5 and 6 located in guides 4 and sliders 2 , wire cutting mechanisms containing movable 7 and fixed 8 sleeve knives, and a nest for accommodating parts of the product 9 connected by means of a lever 10 with a limit switch 11.

The guides 4 slides in the sleeves 12 and 13, which are attached to the frame

I, on the sleeves 12 are stops 1. By means of the levers 15 and 16, the guides are connected to the stem 17 of the feed cylinder 18, a cam 19 is fixed at the end of the stem, which presses the limit switch 20, which determines the extreme position of the stem.

The fixed sleeve knives 8 are clamped in the fixed bracket 21 attached to the bed 1, and the movable knives 7 are located in the movable fork 22, which by means of the lever 23 is connected to the stem 2 of the membrane cylinder 25, which informs the movement of the fork 22, which returns to its original position by a spring 26. A cam 27 is fixed on the lever 23, which presses the limit switch 28, which determines the extreme position of the rod 2.

Semiautomatic works as follows.

Press the lever 10 and carry out a preparatory cycle of work, feeding the wire into the sleeve knives and cutting the axle. The product is inserted into the socket 9 while pressing the lever 10 associated with the limit switch

II, which includes an electromagnet of the pneumatic distributor 29, and compressed air through the pipeline 30 enters the rod cavity of the feed cylinder 18, moves through the rod 17 and levers 15

and 16 is transmitted to the sliders 2 and guides, the ball mechanisms located in them clamp the wire and, by pulling it together with the slide of the sliders and guides, push the axes located in the movable blades 7 into coaxial ones. openings of connected parts of the product.

The sliders 2 simultaneously with the guides 1 move up to the stop, after which the sliders stop and the guides continue their turn, while the ball mechanism 6 of the clamp passes the wire. The rod by means of the cam 19 presses the limit switch 20, which de-energizes the electromagnet of the pneumatic distributor 29, and the air through the pipeline 31 is fed into the other cavity of the cylinder 18, resulting in guides 4, sliders 2 and

The straightening mechanisms of the wire located therein reverse, drawing the wire out of the product, and the slider begins to move backwards when the finger 3 has gone through the groove, while the wire will be pulled out of the product until the sliders 2 reached the stops. Runners 2, 10 reach the stops 1, stop, their ball mechanisms. 6 wedge the wire that has left the product, and

the ball mechanisms 5 of the clip, on the guides 4, continuing to reverse, slide along the wire until the fingers 3 pass through the grooves of the runners 2.

The connected product is removed from the socket 9, the lever 10 is released and the limit switch 11 is turned off, which turns on the air distributor 32, and. compressed air through line 33 enters the membrane cylinder 25, the cylinder rod through the lever 23 drives the fork 22, cutting the wire and cut axes in moving blades, the cam 27 at the end of the lever 23 presses the end switch 28, switching the pneumatic expansion valve the valve 32, the air exits the cavity of the membrane cylinder. Spring ZB returns the stem back, and spring 26 returns the plug 22 to its outcome.
