A new type of tensioning device for vulcanized fuselage

Abstract

The present invention relates to a new type of tensioning device for a vulcanized body, which includes a workbench, a hydraulic stretching device, a vulcanization positioning device, and a moving guide for a screw rod bearing assembly. One end of the extrusion rod is connected to the hydraulic pump, and the other end of the extrusion rod is connected to the limiting block. A through-hole connecting slideway is arranged on the workbench, and the limiting block passes through the through-hole connecting slideway. This new type of tensioning device for a vulcanized body is newly composed of a hydraulic stretching device, a vulcanization positioning device, a moving guide for a screw rod bearing assembly, and a special hydraulic installation body. The device is set to be detachably connected, which facilitates the overall maintenance of the device and the replacement of components. During vulcanization work, at the theoretical position, the vulcanization positioning device extends upward to perform vulcanization positioning. In this way, when vulcanizing V-belts of the same specification length, the theoretical position of each batch of production is the same, and at the same time, the rotation of the vulcanization wire is prevented, which improves the service life of the screw nut.

Description

Technical Field

[0001] The present invention relates to the technical field of flat vulcanization mainframes, and particularly to a new type of vulcanization body tensioning device. Background Art

[0002] As is well known, the existing vulcanization body tensioning device is an auxiliary device for a flat vulcanization mainframe, and it has been widely used in the technical field of flat vulcanization mainframes.

[0003] During the V-belt vulcanization operation of the traditional vulcanization body, the lead screw drive assembly and the power input assembly drive the lead screw guide assembly to move back and forth to the designated working position of the body. When the lead screw rotates, it not only has to bear a large radial force but also a large axial force. The service life of the lead screw nut is short, and after working for a period of time, the gap between the lead screw and the lead screw nut becomes too large. For the same specification and length of V-belt, there is a large deviation in the designated theoretical position during vulcanization stay, resulting in the same vulcanizer producing V-belts of the same specification, and the result is that the length deviation of the V-belts is too large, leading to defective products and waste products, and resulting in high production costs and other adverse consequences.
