A kind of peripheral forming tool holder type milling assembly

Abstract

The invention discloses a circular forming knife rest type milling assembly which comprises a circular forming cutter head base body, wherein a knife rest type milling assembly is arranged on the edge of the base body; at least two columns of cutting blades are arranged on the knife rest type milling assembly; and the two columns of cutting blades are arranged in a staggered mode in a direction perpendicular to the circular cutting direction. According to the knife rest type milling assembly disclosed by the invention, blank parts of various materials can be subjected to circular forming milling, the knife rest type milling assembly is particularly applied to milling the railway rail head profile and has the advantages of convenience in blade maintenance, convenience in knife rest storage, high tool track machining expandability and the like, and the development of the circular forming, particularly the development of the circular forming technology of the railway rail head profile and the tool application, is promoted.

Description

technical field [0001] The invention relates to a circular forming tool holder type milling assembly, which can realize the forming processing of blanks of various materials, in particular a milling assembly suitable for circular milling to form railway steel rails with different rail profiles. Background technique [0002] As an infinitely long beam supported on a continuous elastic foundation, the rail mainly bears the concentrated vertical load from the rolling stock and generates a certain bending moment on its section. The rail includes the rail head, the rail waist and the rail bottom. At the contact with the vehicle tread, with the increase of operating time, various diseases will occur, such as corrugation, flash, uneven joints, etc., which will affect the comfort of running trains and accelerate the loss of rails. Therefore, it is necessary to treat the rails. The rail profile is reshaped on-line to extend the service life of the rail, improve the comfort of running...

AI Technical Summary

Problems solved by technology

The above-mentioned disassembly and replacement workload is large, and when the outer dimension of the disc base is large, the instruments required for re-testing and adjusting the position of the cutting blade after replacement are also relatively large, and the detection and debugging work is complicated; in addition, the replacement of the milling disc takes up a lot Large space, especially for online forming equipment, the replacement, detection and adjustment of worn blades will lead to complex design of forming equipment, the size of the equipment used for tool storage and detection space is too large, and the equipment cost increases.
