Problems solved by technology

In the above-mentioned methods, the high-temperature remelting processing method adopted by people is oxygen-acetylene flame heating or the method of ion beam and electron beam. The crystal grains of the melted material are coarse, and the performance obtained is not ideal; and because of the manual operation, the efficiency is low and the product quality is unstable

Embodiment Construction

[0011] figure 1 , figure 2 Among them, the present invention includes a workpiece moving / rotating mechanism and an induction heating moving mechanism.

[0012] Workpiece moving / rotating mechanism: the machine tool body 1 has a spindle box 2 and a tailstock 8 which are arranged opposite to each other and are used to clamp the workpiece 3 and drive the workpiece 3 to rotate. The machine guide rail 4 can make the tailstock move axially. The tailstock 8 is equipped with the top sleeve 7 that can automatically expand and contract to meet the thermal expansion requirements of the workpiece. A chuck 24 that can drive the workpiece 3 to rotate is arranged on the spindle box 2 . The spindle box 2 is connected with the numerical control system 21 . The workpiece 3 clamped by the headstock 2 and the tailstock 8 is inserted into the inductor 5 capable of heating the workpiece. 22 is the main shaft box variable frequency motor.

[0013] The sensor heating moving mechanism is: the ou...

Abstract

The invention provides an induction remelting machine tool for induction remelting of an alloy (ceramics) powder coating and a metallic base material.The machine tool body is provided with a main spindle box and a tail bracket which are arranged in opposite direction, assist in clamping workpieces and drive the workpieces to rotate; the workpieces clamped by the main spindle box and the tail bracket are sleeved into an inductor which can heat the workpieces, the inductor is arranged on a carriage which can drag the inductor to do reciprocating motion.The machine tool of the invention solves the defects in the prior art that remelting temperature control is not accurate, the workpieces are not preheated and heated evenly, the remelted crystal grains are coarse, the remelting efficiency is low, the production quality is not stable and the like. The machine tool of the invention has the advantages of quick and even remelting temperature rise, small deformation of workpieces, high quality remelting, fine crystal grains in an induction remelting coating, high surface hardness value, and superiority of the corrosion resistance and abrasive resistance of the coating to the corrosion resistance and abrasive resistance of oxyacetylene flame remelting coating with more coarse crystal grains, low cost in technology investment and production and the like.

Description

technical field [0001] The invention relates to a machine tool for induction re-fusion of alloy (ceramic) powder coating and metal base material. Background technique [0002] In the prior art, in order to obtain parts with special properties, people spray alloy (ceramic) powder on the surface of the metal substrate and then use high temperature remelting to obtain some special properties on the surface of the parts. In the above-mentioned methods, the high-temperature remelting processing method adopted by people is oxygen-acetylene flame heating or the method of ion beam and electron beam. The crystal grains of the melted material are coarse, and the performance obtained is not ideal; and because of the manual operation, the efficiency is low and the product quality is unstable. Contents of the invention [0003] The object of the present invention is to provide an induction remelting machine tool for induction refusion of alloy (ceramic) powder coating and metal base m...
