AUTOMATIC MACHINE FOR MANUFACTURING FROM METAL TAPE OF CREATIVE DETAILS WITH A TONGUE PLOT

It was filed on April 4, 1955 t. No. 6534у452273 to the Ministry of Electrical Industry of the USSR

This invention relates to automatons For the manufacture of metal-shaped, brace-like parts with a flat section (such as not pieces for electric machine manifolds).

According to the invention, in order to increase the productivity of the automaton, the working unit consists of a matrix with a through-forming mold, located right under the mold of the molding rod and mounted above the matrix of the bending punch driven by the rotating cam. The cam configuration during the working stroke of the punch makes it possible for the workpiece (strip of tape) to push the last through the die's nest and bend the workpiece into the bracket, and during the return stroke, temporarily place the insert in the intermediate position FOR molding (flattening) during this stop pulled out the matrix of the part of the bracket with the forming slider and the subsequent raising of the poapson to release the finished part and return it to its original position.

The automatic cutting of blanks of parts from the tape before forming the staples in the machine is carried out using the second punch.

A pneumatic CYLINDER is provided for driving the molding drift in the machine, which is supplied with an electro-pneumatic valve controlled by a limit switch operated by a cam-cam mechanism of the bending punch.

The drawing schematically shows the yi.-triage of iredlol: automath.

Coming from the drum, the belt is trimmed in the milling device (1) and fed by the mechanism (2) working from the main drive shaft (3) of the machine and carried out a single feed of the tape in accordance with the specified size (driven from the shaft to the drawing is not "shown).

After the tape feed is finished, the cam (4) located on the main shaft (3) on the HIHOHKC presses i) the lever (5), which through the roller (G) he slides a slider with a cutting punch (7), cutting the tape in the die (8). ). Following this cam (9). also located on HiHi; HKS on the bank (3), the h.rgznlk (10) is located on the slide with the flexible r punch (I), which bends the part, nothalky a piece of tape into the die (12).

When the slide is reversed up (under the action of the inlets and the 13), the roller (10), skol 110 segment (a) of the cam curve (9). causes a temporary stop of the punch (I) in the intermediate floor ;; H 111. At the same time, the cam tooth (14) presses the limit switch lever (15). including the coil (16) of the electronic valve (17). Clans (17)

switches air from the air network into the lower cavity of the pneumatic cylinder (18). The piston of the cylinder of the cherille lever (19) will move the molding ish (moons (20), which will mold (flatten) the outgoing and; matrices (12) part of skpba (21).

When the cam tooth (14) soygt: pwiaga limit switch (15). The value of the coil (16) of the electrochemical valve (17) opens and the i03iyx begins to enter the upper ashlost of the Chi. tshdra (18), thereby returning jii) .i: iyii

(20) to the starting position.

lipii, the far 1dem of rotation of the spout (9) is the rise of the nuanson (11) and the initial position, and the part is ready

(21) is released and falls down. Following this, further

According to the tape, the tags are set to the tag and vep, pskki. well done.

The return of the slider with a cutting punch (7) takes place under the rod, s (22).

Claims (4)

1. An automatic machine for the manufacture of metallic metal. mites of stapled parts with a slice (like cockerels for collectors of ektrichkskih machines), o and ni and fi with that, for the purpose of poy1ieni) g productivity :, its oriental node consists of a matrix with a through forming nest located under the mold of the forming drift and installed by the matrix of the bending punch driven by a rotating cam, the configuration of which cuts during the working stroke of the punch the pushing of the workpiece through the forming nest of the die and bending the workpiece at this ope) strap into the bracket, and during the Reverse move - a temporary stop of the puapson in the pro-intermediate nano-step for molding (thickening) during the 3Toii stop of the slide 11 from the die part of the strap using the indicated slider and the subsequent raising of the punch to release the finished part n 1; :) initial position. 2. In the machine according to claim 1, use irroporo poapsop to automatically cut blanks of parts from the tape before forming the staples. 3. In the machine on PP. 1 and 2 use a hopper cylinder to drive the forming slider. 4. In the machine according to p. 3, the application of an electropneumatic valve, which controls the air supply to the Pneumatic Zilgndr and which is turned off by a limit switch, driven from the B. pulley mechanism of the bend of the HvancOHa bending machine.
