Multifunctional returning mechanism

Abstract

The invention relates to a multifunctional returning mechanism which is provided with an upper disc spring sleeve, wherein the upper disc spring sleeve is mounted on the upper part of a stepped hole of an operating platform through a lubricating bearing; the two ends of a disc spring are mounted in the stepped holes of a lower disc spring sleeve; a positioning screw rod is sleeved in a hole of the disc spring; the upper end of the positioning screw rod is fixed with the upper disc spring sleeve through a thread; and the lower end of the positioning screw rod is mounted on a machine body through the lubricating bearing. The scheme is adopted, so that athe returning spring mounted in a central hole of an operating platform plate is utilized to return the materials, and the defects of complex structure, difficulty in mounting, large space occupied by cylinders and unsuitability for multi-station machinery of the present returning device are effectively overcome.

Description

technical field [0001] The invention relates to a material return mechanism, in particular to a multifunctional material return mechanism, which belongs to the technical field of pressure machinery. Background technique [0002] At present, there are generally two types of material return devices for presses. One form is to install polyurethane plates or springs in the mold to achieve material return, and the other form uses cylinders to eject materials. However, due to the above two forms of material return The device has a complex structure, is difficult to install, and the cylinder occupies a large space, so it is not suitable for use on a multi-station machine. Contents of the invention [0003] The purpose of the present invention is to provide a multifunctional material return mechanism to overcome the above-mentioned defects in the existing material return device. [0004] The technical solution adopted by the present invention to achieve the above object is: the m...
