SU1747228A1 - Die for riveting of stack of magnetic core - Google Patents

Abstract

Usage: electrical and radio industry for joining sheet metal parts by riveting. SUMMARY OF THE INVENTION: A package of magnetic core with rods is placed on the pusher. The pusher moves the bag to the riveting zone, after which the pusher returns to its original position, and the bag is pushed against the check box. slides off the pusher and remains in the work area. After that, the bag is pressed against the base stop. When this cutter under the action of the spring leaves the working area of the riveting. After this, the rods of the magnetic core packet are riveted. 3 il.

Description

The invention relates to the processing of metals by pressure, in particular, to the riveting of assembled plates of a package of a magnetic circuit, which is recommended for use in the electrical and radio engineering industry.

Stamps are known that contain a stepper conveyor, guides for moving parts.

The disadvantage is the absence of a pusher with a ledge on which bags with rivets without heads could be transported.

A known stamp for assembling a magnetic core, comprising upper and lower plates connected by columns and bushings, a plunger holder with a set of punches, a clamp with a buffer, a movable liner, allows to install a package with inserted rods outside the working area of the stamp.

The disadvantage of the stamp is that it is only possible to manually install the assembled packages with rods in the riveting zone and also to remove them manually after riveting.

The purpose of the invention is to provide automation of the riveting cycle and increase productivity.

This goal is achieved by the fact that the slider is made with an emphasis, and the feed mechanism is made in the form of a guiding element, the plane of which coincides with the plane of the lower clamp of the bag, and is mounted on it with the possibility of reciprocating movement of the pusher, while the orientation mechanism of the bag is fitted with bottom plate swivel spring loaded ryVI

A chaser with a flag mounted to interact with the stop of the slider on the orientation of the package.

FIG. 1 - stamp at the bottom dead center without top Ylita; FIG. 2 is a section A-A in FIG. 1: in FIG. 3 shows a section BB in FIG. 2

The stamp for the riveting of the packet of the mill pipe consists of the upper 1 and: hopper 2 plates connected by columns 3 and bushings 4. Punch holders 5 with punch 6, buffers 7, upper and lower clamp 8 are mounted on the upper 1 and lower 2 plates. For transportation unmixed bag 9 there is a pusher 10, made with a stop 11.

The stamp is provided with a feed mechanism made in the form of a guide element 12, the plane of which coincides with the plane of the lower clamp 8, and installed on it with the possibility of reciprocating movement of the plunger 10.

For the orientation of the package 9 with respect to the punches 6, there is an orientation mechanism equipped with a rotatable spring-loaded lever slam-fit 13 with a flag 14 mounted on the bottom plate 2

interaction with the stop 15 of the slide 16 of the orientation mechanism. The slider 16, which interacts with the pneumatic cylinder 17, in the front part has a rectangular recess equal to the dimensions of the package 9, which pressing the package against the base stop 18, will create a chamber for the package 9, which prevents its deformation during riveting.

There is a tray 20 for removing the finished bags. There is a stop 21 for fixing the lever compartment during riveting. For removing the package 19 after riveting the bag 19 from the slide 1 b, a stop 22 is installed.

The stamp works as follows.

After the next operation, the assembled packet 9 of magnetic core with rods is automatically placed on the pusher 10. Then, on command, under the action of a pneumatic actuator (not shown), the pusher 10 moves along the guide element 12. From the displacement along the pusher, the package 9 is held by the stop 11. The pusher 10 with the package 9. passes the riveting zone, pushes the finished package 19 out of the riveting area onto the tray 20, so that it does not interfere with the moving parts of the stamp, and then, on command, the reverse movement begins; Package 9, butt against the flag 14 of the trimmer 13, leaves the pusher 10 in the riveting zone. The air is then supplied to the backflow part of the pneumatic actuator 17, which begins to move the slider 16, pressing the bag 9 to the base stop 18. In this way, the stop 15 releases the lever of the shutter 13, which under the action of the spring leaves the area of the moving parts of the die,

mesh riveting. After pressing the slide 16 to the base stop 18 of the package 9, the press is activated and the die is riveted on the upper and lower sides of the package 9.

When the punch returns to the top dead center, air is supplied to the rod part of the pneumatic actuator 17. The latter removes the slider 16, releasing the finished bag 19 by means of the stop 22.

When the slide returns, the stop 15 presses one of the shoulders of the shutter 13, returns it to the working state. The stamp is ready for the next riveting package.

The proposed stamp allows to automate the riveting of a package of magnetic core with rods, freeing a person for this operation, increases productivity.
