Abstract

The invention relates to light industry, in particular, to footwear production equipment, can be used to invert blanks of home footwear, manufactured in an inverted way, and can improve reliability and improve working conditions. The proposed device is additionally provided with hinged levers fixed to the frame symmetrically with respect to the hollow elliptical mandrel, clamps spring-loaded to it to hold the inverted product when the toe of the workpiece is straightened and capable of interacting with the outer walls of the hollow ellipsoidal mandrel. The device also has rollers, the axes of which are located at the free ends of the articulated levers perpendicular to the latter, which are designed to interact with the carriage stops. The punch is made with a U-shaped groove in its lower part for fixing the seam of the toe of the workpiece and is spring-loaded relative to the ejector located between the walls of the U-shaped groove of the punch. 3 il.

Description

The invention relates to light industry, in particular, to footwear production equipment, and can be used to invert blanks of homemade shoes produced in a reversible way.

The purpose of the invention is to increase reliability and improve working conditions.

Fig. 1 is a schematic diagram of the device; figure 2 is a view of And figure 1; FIG. 3 is a flow diagram of a technological operation using the device: a — putting the workpiece on the mandrel; b - capture the workpiece by the punch and entry into the mandrel; in - a clip of edges of preparation; expansion of a nasal part; g-termination of the inversion of the workpiece; d - return mechanisms to its original position, removing the workpiece,

A device for turning in hollow volumetric articles comprises a frame 1 with vertical guides 2 rigidly fixed on it, a carriage 3 on which an ejector 4 is rigidly fixed, and a spring 5 relatively spring-loaded relative to the ejector 4 with a U-groove in its lower part for fixing the seam of the toe part of the workpiece and spring-loaded relative to the ejector 4 located between the walls of the U-shaped groove of the punch 6. On the base 1 there is an ellipsoidal mandrel 7 for putting on the workpiece 8 and two n dpruzhinennyh springs 9 hinged lever 10, the ends of which are mounted spring-loaded clamps 12 by springs 11 and rollers 13, adapted vozmozhnovj O

Interaction with the stops 14 of the carriage 3. On the base 1 there is an actuator, for example a pneumatic chuck 15, connected to the carriage 3.

A device for turning in hollow volumetric products works as follows.

The operator puts the stitched workpiece 8 on the ellipsoidal mandrel 7 and turns on the drive. Air is fed into the upper cavity of the pneumatic cylinder 15, which lowers the carriage 3 along the vertical guides 2. Punch b captures the U-groove seam of the workpiece 8 and enters the inside of the mandrel 7. Fixing the seam eliminates the possibility of jamming the workpiece 8 between the punch 6 and the inner surfaces of the mandrel 7 The stops 14 of the carriage 3 are located on the rollers 13 of the hinged levers 10, the clamps 12 of which press the edges of the workpiece 8, allowing the ejector 4 to smooth out the seam of the toe part of the workpiece 8 during the subsequent course. with the abutments 14 under the action of springs 9 articulated arms 10 diverge, there is a complete inversion of the preform 8. At the lower end position the drive is automatically switched. Air is supplied to the lower cavity of the pneumatic cylinder 15. returning all the mechanisms to their original position, while the ejector 4 is drawn into the punch 6 by the action of the spring 5. The removed billet 8 is removed through the groove of the mandrel 7. The cycle of operation is repeated.
