(54) DEVICE FOR SUBMITTING STRIP MATERIAL TO A TREATMENT AREA

(57) The invention relates to the processing of metals by pressure and can be used to supply soft and thin materials to the treatment area. The goal is to increase the accuracy of the feed pitch when stamping soft and thin material blanks and to increase productivity. The strip material is manually fed to the treatment area. At the entrance to the treatment area there is a roller, the diameter of which is equal to the feed pitch. On the video clip is rigidly fixed. When turning the roller on the feed step, the plate presses the sensor, which gives the command to activate the brake. The material stops and cuts off its cutting. 3 il.

The invention relates to the field of metal forming and can be used to supply soft and thin materials to the treatment area.

The purpose of the invention is to improve the accuracy of the feed pitch when stamping soft and thin material blanks and to increase productivity.

FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - basic electrical circuit.

The device contains a lower fixed plate 1, a matrix 2 rigidly fixed on the lower plate, a punch 3 rigidly fixed on the movable upper plate, a punch 3, a puller 4 and guide lines 5 rigidly fixed on the matrix, a roller 6 reinforced with rubber mounted on an axis in a puller interaction with the strip and the material to be tamped, the bar 7 fixed on the roller, which interacts with the sensor 8 fixed on the puller, the electromagnet 9 mounted on the puller, which in the working position by the core It is divided into a formed strip material, the spring-loaded clamp strips to the roller 10, a lever 11 for removal from the pressing roller during filling strip.

The device works as follows.

When the press slider is in the upper position, the strip is filled when the lever 11 is pressed and advances until the edge of the strip blocks the opening of the die 2. This is monitored through the opening in the puller 4, and the strip 7 of the roller 6 / is in the upper position at the exit From the sensor orifice (reed switch) 8, i.e., with the electromagnet 9 turned on. When the press slider moves down, the part is cut down by punch 3 in the die 2. When the press ram moves upward at the moment when the punch 3 comes out of the hole of the die 2 and releases the lane for movement, the strip advances to the feeding step, and the roller 6, resting on the strip pressed

10, rotates until the strip 7 of the roller 6 enters the sensor orifice (reed switch) 8. At this moment, the electromagnet 9 is turned on, which with its core presses the strip to the surface of the matrix 2, i.e., fixes the advance of the strip exactly at the feed step , because the circumference of the roller 6 is designed for the desired feed pitch. At the extreme lower position of the press ram, the sensor (reed switch) of position K2 is triggered (Fig. 3), the thyristor T2 is turned on, and the thyristor T1 is switched off, the electromagnet 9 de-energizes and allows the tape to move freely.

The device provides the exact specified step size of the feed strip, thus making it possible to save material, excluding losses during deformation of the jumpers. Labor productivity is increased, as it provides for work in the automatic press mode.
