Description

The dies are mounted on the brushes of the pneumatic actuators 16 for movement in guide sleeves 17 fixed to the table 18. The stand 12 rests on a hollow support 19 with a sealing ring 20 connecting the external network of compressed air with the cavity of the stand 12 and hoses 21 with dual air valves 22 feeding pneumatic actuators.

The device works as follows.

The wetted botanical workpiece 23 is placed under the raised matrix on the heated punch between the restrictive plates 3, slightly twisted around the punch. Then, pressing with both hands on the handles of the double tap 22 to prevent the hands from falling under the matrix, turn on the pneumatic actuator 16. The die is lowered, the shoulders 5 of the side clamps touch the stop 4, the shoulders 8 turn, bend the rounded edges of the punch 2 with the botanum and press it in

Laying 11, pressing the ends of the botan piece a little earlier than its plate 6 touches, and as the plate is further lowered, the blank is pulled out.

The bot's shaping is completed within a full turn of the punch around stand 12, alternately turning all the punches towards the performer. Spin the tap handle 22, raise the matrix and remove the finished part from the punch.

Gormula invention

A device for shaping leather goods items, preferably bags, containing punches mounted on a turntable, a matrix mounted for movement in a vertical direction, and an actuator, characterized in that 5, in order to improve the quality of molding and reduce material consumption, each punche has restrictive plates for the part and a spring-loaded stop, and the matrix contains a plate and side clamps, made in the form of hinged two-shoulder spring-loaded snarl on the plate gov, one shoulder of each of which is installed with the ability to interact with the emphasis of the punch, the other with molded parts, each punch has a corresponding one. the matrix.
