Description

The utility model relates to radio electronics, in particular to technological equipment for preparing the conclusions of radio elements of various sizes for mechanized soldering on printed circuit boards in small-scale and large-scale production.

The invention is known "Device for forming and trimming the conclusions of the radio elements" (AS No. 1148135 from 04/11/1983), containing a base on which are mounted movable carriages, U-shaped punches, detachable knives, cassettes for radioelements and a drive, characterized in that it is equipped with copiers mounted on cutting knives, and rockers connected to the carriages and installed with the possibility of interaction at one end with the copiers, and at the other ends with punches of the U-shaped bend, while the protrusions are made on the carriages, and on the cassettes - depressions corresponding to depressions on carriages.

The purpose of the invention is the improvement of operational capabilities. The application of the proposed device in production makes it possible to automate the process of adjusting to size when processing various types of radioelements in a cassette.

In the above description does not indicate the presence of a clamping mechanism for fixing the radio elements in the cassette. Based on this, we can conclude that the clip is installed manually or completely absent.

Another invention is known, “A device for group forming of leads of radioelements” (AS No. 1721867 of January 15, 1990), comprising a molding mechanism in the form of a cutting and forming punches, a clamping mechanism and preliminary bending of leads of radioelements connected to a piston pneumatic actuator, and a matrix that differs the fact that the pneumatic actuator is equipped with plungers with spring-loaded pushers placed in the holes made in the pistons of the pneumatic actuator, moreover, the plunger pushers are installed with the possibility of interaction with the mechanism when press and pre-bending, and the area of each plunger is not larger than the area of the piston located around the plunger.

The aim of the invention is to simplify the design by reducing the associated mechanisms during the sequential operation of the forming and trimming mechanism and the clamping and bending mechanism.

The disadvantage of this device is the unreliable operation of the clamp mechanism due to the complex structure consisting of a lever connected to the slider, the clamp with the spring and many connecting parts.

The closest analogue in technical essence is the invention “Device for forming and trimming the conclusions of radioelements” (AS No. 1699029 from 04/18/1989), containing a base on which the carriage is installed, P-shaped punches, clamp, trim knives, cartridges for radioelements and pneumatic actuator, characterized in that the U-shaped punches with clamp are mounted on the carriage, while grooves for the conclusions of the radioelements located at an angle of 1-1.5 ° to the longitudinal axis of the clamp are made on the working surface of the clamp.

The purpose of the invention is the improvement of operational capabilities.

This design has the following disadvantages:

- The clamp is spring-loaded with only one spring located in the center of the pneumatic cylinder. This can lead to uneven clamping of the cartridge with the findings of the radioelements to the punch. This fact affects the quality of products.

- The presence of grooves for the findings increase the complexity when laying radio elements.

- The presence of a lever for moving the carriage for feeding the cassette is an additional mechanism for the application of which the manufacture of a housing of a special design is required.

The purpose of the proposed utility model is to expand operational capabilities, increase labor productivity, improve quality during the operation of trimming and forming the conclusions of radioelements of various diameters.

This goal is achieved by the fact that in the device containing the base on which the pneumatic cylinders are mounted to move the “zig” punches and trimmed knives, the bracket on which the matrix and pneumatic cylinders are mounted to move the clamp and bending mechanism, the punch, matrix and clamp and bending mechanism consisting of a double clamp with two springs each for reliable fixation of radio elements, made removable for the possibility of trimming and forming the terminals of radio elements of various diameters, and under the base there is a tray for I am collecting cut-off residues of the findings of the radioelements.

The invention is illustrated by figures 1, 2.

In FIG. 1 shows a front view of the device.

In FIG. 2 shows a side view of the device.

A device for forming and trimming leads of radioelements (Fig. 1) consists of a base (1) on which are installed horizontal guides (2) with linear blocks with traverses mounted on them (3) with mounted on them, which in turn form a “zig” -punches (4) and cutting knives (5), two pairs of pneumatic cylinders (6) located on the left and right of the base, for synchronous movement of the traverse (3) in the horizontal plane towards each other. A pair of pneumatic cylinders (8) (Fig. 2) are installed on the bracket (7), which move the clamping mechanism and bending the terminals of the radioelements, consisting of a double clamp (9) with two springs each for reliable fixation of the radioelements and plates (10) for U-shaped bending conclusions of radio elements (Fig. 1). The matrix (11) paired with the “zig” punches (4) determines the shape of the “zig”, is movable, and can be extended by the lodgement (12) and the guide bracket (13) from the position of “loading and unloading of radio elements” to the position of “molding” (figure 2). At the bottom of the base, a tray (14) is inserted into the guides to collect the cut-off parts of the terminals (Fig. 1).

The operation of the device is as follows:

The radio elements are stacked on the extended matrix, after which the matrix is pushed all the way into the device. By means of a manual pneumatic distributor, compressed air is supplied to the pneumatic cylinders (8) to move down the clamping and bending mechanism, which sequentially clamps (9) it fixes the radioelements on the matrix surface (11) and with the plates (10) makes U-shaped bending of the terminals of the radioelements. Next, compressed air is supplied to the pneumatic cylinders (6) to move the traverses (3) towards each other, and when the matrix (11) closes with the “zig” punches (4) and the cutting knives (5), the leads of the radioelements are trimmed, followed by zig-forming . The trimmed parts of the conclusions of the radio elements fall into the tray (14). After the end of the treatment, the air supply to the pneumatic cylinders (8) is stopped and the clamping and bending mechanism returns to its original position, after which the air supply to the pneumatic cylinders (6) located on the right and left of the base and the crosshead with the “zig” punches installed on them is stopped (4 ) and cutting knives (5) also return to their original position. The matrix (11) with the molded elements is manually pushed out of the device by the lodgement (12) and the guide bracket (13), the molded elements are removed. The tray (14) extends from the guides to remove the waste of the conclusions of the radioelements. The process is then repeated.
