Tube drawing device of centrifugal tube drawing bench

Abstract

The invention relates to a tube drawing device of a centrifugal tube drawing bench. The device is composed of a tube drawing pliers assembly and a tube drawing trolley assembly, wherein the tube drawing pliers assembly comprises an expansion cone, a pull rod, a pliers claw, a pliers rod, a wedge block, a reset sleeve, a bearing, a pliers base, a flange, a screw, a gasket, a spring gasket and a nut, and the tube drawing trolley assembly comprises a tube drawing trolley frame, grooved wheels, an axle, a partition plate, a clamp box, a connecting auxiliary seat, a chain connecting block, a blankcap, flat wheels, an adjusting block, an additional spacer bush A, an additional spacer bush B, a paper pad, a shaft end blocking piece, a rail scraper A, a rail scraper B, a shaft check ring, a standard air cylinder and an angular contact ball bearing. According to the device, the size and the shape of an end can be adjusted according to a tube diameter, automatic expansion is achieved through the standard air cylinder so as to enable the device to abut against a tube wall, the grooved wheels at one side of a tube drawing trolley ensure guiding, the device is simple and compact in structure,safe and reliable in performance, flexible in reaction and simple and convenient to operate and maintain, the tube drawing operation can be rapidly, accurately and effectively completed at a high temperature, and an application effect is very remarkable.

Description

technical field [0001] The invention relates to centrifugal casting equipment, in particular to a tube-extracting device for a centrifugal tube-extracting machine. Background technique [0002] At present, when the centrifugal extubation machine performs the extubation operation, the blank temperature is very high, and the extubation device needs to contact the inner diameter of the blank, so excellent high temperature resistance is required, and the blank needs to be pulled out within a specified time, otherwise the production efficiency will be affected. The temperature of the mold is lowered, so the stability of the extubation device is required to be higher. [0003] Although the existing extubation device is simple in structure, its action accuracy is poor, and it cannot quickly and effectively complete the extubation operation at high temperature, and its fixed and single structural design cannot meet the needs of serial production of various pipe diameters.
