High-precision heating spinning flaring device

Abstract

The invention relates to the technical field of forklift hub flaring, and discloses a high-precision heating spinning flaring device. The high-precision heating spinning flaring device comprises a flaring die, a fixed frame and a movable plate, the top of the fixed frame is fixedly provided with a driving motor through a rack, an output shaft of the driving motor penetrates through the top of thefixed frame, extends downwards, and is fixedly connected with the flaring die, the movable plate is located between positions of the fixed frame, the movable plate is located below the flaring die, abottom die is arranged in the middle of the movable plate, a through hole is formed in the centers of the movable plate and the bottom die, the lower surface of the movable plate is fixedly connectedwith a U plate, an air cylinder is fixedly mounted on the U plate, a piston rod of the air cylinder penetrates through the through hole and is fixedly connected with an ejecting block, a supporting plate is fixedly connected between side walls, close to the bottom end, of the fixed frame, two guide cylinders are fixedly connected to the upper surface of the supporting plate symmetrically, according to the high-precision heating spinning flaring device, the lifting stroke of the movable plate can be conveniently subjected to precise and stable control, and the forklift hub flaring precision canbe effectively ensured.

Description

technical field [0001] The invention relates to the technical field of fork wheel hub flaring, in particular to a high-precision heating spinning flaring device. Background technique [0002] The forklift hub is an important structural part related to the safety of forklift driving. Its quality and reliability are not only related to the safety of the vehicle and the personnel and materials on the vehicle, but also affect the stability, maneuverability and comfort of the vehicle during driving. , which requires the hub to have the characteristics of high fatigue strength, good stiffness and elasticity, high precision in size and shape, and light weight. The purpose of the hub flaring process is to expand the straight barrel of the rim to the size required for the next finishing process, and preform for the next process. The flaring accuracy will directly affect the machining size of the subsequent rim. [0003] In the patent with the Chinese patent authorization number CN10...
