SUMMARY OF THE INVENTION: the manipulator for the stamping press comprises support guides mounted in the housing, a carriage mounted on the above-mentioned guides with the possibility of reciprocating movement, a carriage drive, a traverse with gripping bodies, coupled to the carriage, a mechanism for vertical movement of the traverse with two parallel guide rails mounted in the traverse, a lifting roller kinematically connected to the same traverse, a crawler with a copy groove. 1 s.p. f-ly, 3 ill.

Description

The invention relates to mechanization and automation means and can be used in robotic complexes and automatic lines, for example, sheet and die forgings, for loading and unloading workpieces, interoperational transportation

A manipulator for a stamping press is known, comprising a carriage, guiding elements installed therein in the form of rolling pins with a traverse fixed to them, on which gripping bodies are mounted. The carriage is located on the guide and is connected to two telescopic plunger rams mounted in the opposite direction. The traverse is fixed on rolling pins, to which a copy roller is fixed through an intermediate element.

The robot for the stamp precision press works as follows oSFS-zom.

In the initial position, the robot carriage is in the leftmost position, with one gripper located in the magazine device and the other in the stamp. Then the carriage is moved to the rightmost position. In this case, the rod with gripping bodies rises up in accordance with the profile of the copy groove. When approaching the carriage to the right extreme position, the yoke with the gripping bodies is lowered. The workpiece from one grab falls into the stamp, and from the other into the container. Next, the cycle repeats.

A disadvantage of the known stamping press robot is the rigid kinematic parameters (lack of adjustment of the longitudinal and vertical displacements) defined by the copy groove.

The purpose of the invention is to increase the reliability of the manipulator.

The goal is achieved in that the mechanism for vertical movement of the beam is made in the form of two parallel rolling pins mounted parallel to the carriage, an intermediate bar placed on the above rolling pins, movable

springs mounted on rolling pins under the intermediate bar, vertical struts that rigidly connect the intermediate bar with the traverse, while the crawler is placed between two guide elements with the possibility of movement relative to the carriage, the copy groove is made with a U-shaped working surface, and the lifting roller is mounted on intermediate plate with the possibility of interaction with the U-shaped working surface of the copy groove, the angle of inclination of each section between the roller and the working surface of the copy groove, made in the form of two plunger telescopic power cylinders, the housings of which are mounted in the housing, and the rods are fixed on the spider, in the housing on both sides of the guide elements, pairs of adjustable stops are fixed, two of which are designed to interact with the carriage, and the other two are crawling in their extreme positions.

A positive effect when using the invention is achieved under production conditions when creating automated stamping lines and other types of production.

The list of figures of graphic images illustrating the invention (illustrations are presented in the application filed for the invention).

In FIG. 1 shows a manipulator for a stamping press with an average carriage position; in FIG. 2, also, the carriage in the leftmost (initial) position; in FIG. 3 - the same, the carriage in the extreme right position,

Example, the Manipulator to the stamping press contains a crosshead 1 with gripping bodies 2, 3, mounted on spring-loaded rolling pin 4, 5 with the possibility of vertical movement and held in the upper position by springs b on the carriage 7, mounted for movement on horizontal support rails 8, and on the spring-loaded rolling pins 4, 5, through the intermediate bar 9, a lifting roller 10 is fixed, which interacts with the U-shaped working surface of the coffer groove of the crawler 11, located between the two guide elements 8 movable relative to the carriage 7, the angle of inclination of each portion of said working surface polzushki 11. To support guide 8 larger than the angle of friction between the lifting roller 10 and the working surface of the U-shaped groove polzushki follower 11, and the drive is in the form of two plunzher-

telescopic power cylinders 14, 15, the cases of which are mounted in the case, and the rods 12, 13 are mounted on the creepers 11, while in the case with two

the sides of the supporting guide elements 8 are fixed in pairs with adjustable stops, two of which 18, 19, by means of the flywheels 16, 17 with the possibility of interaction with the carriage 7, and the other two 22, 23, by means of the flywheels 20, 21 - with the slide 11 in their extreme positions .
