Method for relieving hot-pressing thermal deformation of composite permanent magnet material

Abstract

The invention relates to the technical field of thermal deformation, and discloses a method for relieving hot-pressing thermal deformation of a composite permanent magnet material. The composite permanent magnet material comprises a base, the top of the base is fixedly connected with a fixing mechanism, and the top of the base is fixedly connected with a supporting rod. According to the method forrelieving hot-pressing thermal deformation of the composite permanent magnet material, a crank is rotated, a sliding block moves left and right on the outer side of a threaded rod, an air cylinder further drives a cutting mechanism to move left and right, and therefore the effect of conveniently adjusting the cutting position is achieved. When a rotary knob is rotated, a round nail drives a firstclamping rod to rotate at the moment, a second clamping rod further drives a sliding rod to move left and right, the limiting block can move left and right in the fixing mechanism at the moment, andtherefore the effect that the cutting mechanism is firm in fixing effect is achieved. After the limiting block fixes an object needing to be cut, a heat dissipation pipe absorbs part of heat generatedby cutting heat dissipation through the heat dissipation holes, and therefore the effect of relieving the thermal deformation situation during material cutting is achieved.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a method for alleviating the hot-pressing and thermal deformation of composite permanent magnet materials, which has the advantages of relatively reliable fixing effect of the cutting mechanism and alleviating the thermal deformation during material cutting, and solves the existing problems. In the process of cutting the composite permanent magnet material, the high temperature generated by the cutting device will cause thermal deformation of the composite material due to the concentrated heat of the object during the cutting process, which will reduce the quality of the product. The fixing mechanism of some cutting devices is not reliable, which may easily lead to the deviation of objects during the cutting process, which may lead to the problem of product scrapping
