Abstract

The invention relates to equipment for shoe manufacturing and advantageously improves the reliability of cutting down shoe parts. The press has a body with vertical guides. A sole with a glass is installed in a housing with guides. Rolling pin is briskly installed in a glass with a sole. The lower part of the glass is spring-loaded and is connected through the hole with the cylinder stem in the lower part of the body. Rolling pin with a striker is connected to the hydraulic lifting. In the initial position, the sole is removed from the working area. The pin with the rolling pin is in the highest position. After installing the cutter with a gear-rack mechanism, the tumbler with the sole is turned into a cutting zone. A hydraulic movement of the vertical movement of the rolling pin with the head is actuated. In this way, the cutting of the top of the shoe is made. Reliability of cutting is increased by eliminating cantilever loads on the sole. 3 il.

Description

The invention relates to equipment for shoe manufacturing, namely, punching presses for cutting out the details of the tops of a shoe.

The aim of the invention is to improve the reliability of cutting down parts of shoes.

FIG. 1 shows a press, side view of FIG. 2 - the same, top view; in fig. 3 - the same general view.

The sole 1 is free to rotate relative to the striker 2 and is spring-loaded to it by a spring 3. The sole is rigidly fixed to the glass 4 placed in the guides of the housing 5. The tooth 6 is cut into the glass, interacting with the rack 7 of the gear-rack-and-pinion turning mechanism. Rolling pin 8, with pin 2 fixed on it, is mounted in glass 4.. Rolling pin 8. In the lower part has a hydraulic cylinder 9 for moving it.

Work on the press is carried out as follows.

In the initial position, the sole 1 is removed from the working area. Head 2 is in the upper position above the working area and does not interfere with a good view of the surface of the material and the installation of the cutter. After the cutter is installed and the press is turned on, the sole 1 fixed rigidly on the cup 4 is rotated by the rack 7 gear and installed in the working position under the hammer 2. Then, when the hydraulic actuator 9 is activated, the rolling pin 8, the striker 2 and the sole 1 with the cup 4 move down to the cutter.

In the process of cutting through the material, the impact of the detraction 2 is transferred to the sole 1. With this transfer, the deformation forces of the sole 1 do not depend on the deformation of the striker 2 and the rolling pin 8. After the cutting, the spring-loaded sole 1 with glass 4 rises following the striker 2 with a rolling pin 8, and finally the sole 1 is retracted from the working area by turning the cup 4.
