Description

I

The invention relates to the processing of metals by pressure and can be used in devices for the manufacture of an article by punching and cutting.

A known apparatus for making 5 canvases, comprising a punch punched on a top plate of a table, a punch cut, as well as a mechanism for feeding the tape to the punch and the roll he will go.

The disadvantages of the known installation are the low quality of the obtained products, low productivity and unreliability of work.

In order to improve the quality of the received J / my products, the proposed installation is equipped with a clamping mechanism for the processed tape, made in the form of a bar connected to the rod of the main power cylinder, installed on the 90 top plate of the table, and the mechanism of orientation of the tape relative to the dies, made in installed on the possibility of lateral movement relative to the table, there are 25 l of them, while the tape feed mechanism is made in the form of drive-shaped L-shaped stops from the additional ram and clamps, sleep zhonnyh individual actuator. thirty

FIG. 1 shows the proposed installation, a general view;, FIG. 2, view A of FIG. in fig. 3 - type B of FIG. one.

The plant for making cloths comprises a table 1, to which a force frame 2 is attached, consisting of an upper plate 3 and a lower plate 4 and struts 5. On the lower plate 4 there is a tape feed mechanism 6 made in the form of rods 7 pivotally connected with the rod of the additional power cylinder 8. At the ends of the rods 7, the clamps 9 are fixed, made in the form of stationary l-shaped stops 10 and the clamps 12 that are movable from the actuator 11. The clamps 9 are retracted in the direction of the rolling pin 13.

Attached to the upper plate 3 of the power frame 2 are a belt pressing mechanism 14, a punching punch stamp 15 and a cutting punch 16. The belt pressing mechanism 14 consists of a clamping bar 17 connected to the stem of the main power cylinder 18 mounted on the upper plate 3 plate 3 fixed orientation tape. relative to the axis of the dies 15 and 16 mechanism

19, made in the form of guides

20 having the ability to move across the table with a screw 21 s

left and right thread. To the front wall 22 of the table is attached the mechanism 23 bcc at the pitch and the mechanism 24 for calculating the details. For the initial filling of the ribbon into the dies, a manual feed mechanism 25 with a spring-loaded roller 26 serves.

The silo frame 2 is the working area where the main technological operations take place (punching holes in the web section and waste disposal), B feeding mechanism; tape serves to capture a strictly defined length of the tape and feed this yiiacTKa into the work area. The belt-pressing mechanism 14 is intended to clamp and hold in the clamped position a section of the tape fed into the work area until the end of the punching or punching and cutting operation.

The mechanism 23 for counting in pitch is intended for counting a strictly defined number of working strokes of the mechanism 6 for grabbing and feeding the tape and turning on the cutting die 16 at the end of the counting cycle. The mechanism 24 of reference parts is designed to turn off the installation, when the length of the remainder of the tape in the roll 27 is less than the length of the canvas. The tape 28 is manually pulled from the roll 27 by a pair of rollers, one of which is spring-loaded to the length necessary to be pressed by the pressing mechanism 14. After pressing the tape, the tape section 16 is pressed, the stamp is then returned to its original position, and the tape is pressed down. 12 to the L-shaped anvil 10. After this presses, we release 14 the lenga and, the cylinder 8 feeds the tape either: the specified yag, then the punch 15 punch die works. After feeding the tape by the number of steps, determined by the mechanization of 23 steps in a step, the cut-off stamp 16 is activated. Stop setting

ki comes from the command of the mechanism 24 of reference parts, which is configured to the number of parts depending on the length of the tape in the roll.

The sequence of operation of all the mechanisms in a certain order is carried out by the terminal power / user (not shown in the drawings), which give the command to turn on: one or another cylinder.

The proposed installation allows the quality of the product to be improved since the belt is in a tight position and also to improve the performance and reliability of operation.
