Embodiment Construction

[0022] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0023] refer to figure 1 with figure 2 , a wheel-to-wheel flexible spinning process suitable for steel plate welding wheels with grooves, including the following steps:

[0024] In the first step, under the condition that the blank rotates, two independent first core molds 2 and second core molds 4 having the same groove shape as the inner surface of the target workpiece 6 are symmetrically placed inside the cylindrical blank 1, The first mandrel 2 and the second mandrel 4 are in contact with the inner surface of the cylindrical blank 1, the height of the first groove of the first mandrel 2 and the second mandrel 4 is relative to the height of the cylindrical blank 1 and the target workpiece 6 The distance from the first groove of the to the bottom surface is the same;

[0025] In the second step, two independent first rotary wheels 3 and second rotary wheels 5 w...

Abstract

Disclosed is a two-roller flexible spinning technology applicable to steel plate welded wheels with grooves. Two mandrels provided with grooves identical with target workpieces and two spinning wheels complementary with single grooves are used, and belt wheel grooves are machined in a mode that the spinning wheels spin out of the grooves one by one from bottom to top. According to the two-roller flexible spinning technology, large equal-wall-thickness belt wheels can be machined conveniently, the adaptability is high, the machining range can be expanded without replacing the mandrels and the spinning wheels, and the working efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of grooved wheel spinning, in particular to a counter-wheel type flexible spinning process suitable for grooved steel plate welding wheels. Background technique [0002] Wheels with grooves, including belt pulleys and rope pulleys, are important transmission parts. The traditional processing method is to use casting and forging blanks to be processed by cutting. Poor industrial and mining, the product has the disadvantages of low precision, bulky, large moment of inertia and so on. With the application and development of spinning technology in the field of metal plastic processing, steel plate welding wheels have gradually replaced traditional processing such as casting and forging in many fields due to their advantages such as light weight, high production efficiency, energy saving, material saving and good dynamic balance. The grooved wheel is widely used. The existing grooved wheel spinning process main...
