Problems solved by technology

[0002] Under the prior art, the front and rear rolling wheels of manual trucks are generally processed by casting, but the wheel core produced by this method is not only weak in strength, but also difficult to process and high in cost. The material is generally cast iron, but its The weight of the wheel core is larger than that of the steel core, which is costly and not environmentally friendly

Embodiment Construction

[0013] A method for processing a stamped wheel core according to the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] As shown in accompanying drawing 1, a kind of processing method of stamping wheel core comprises the following steps:

[0015] A. Put the metal pipe 1 into the mold 2, and shrink one end of it by stamping;

[0016] B. Process the other end of the metal pipe 1 according to the method in step A to form it symmetrically with the other end.

[0017] The mold 2 is a hollow tubular design with an inner diameter ranging from large to small.

[0018] The mold is a cold pressure mold or a hot pressure mold.

[0019] The embodiments described above are only one of the more preferred specific implementations of the present invention, and the usual changes and replacements performed by those skilled in the art within the scope of the technical solutions of the present invention should be in...

Abstract

The invention relates to the processing field of wheel cores, which particularly provides a processing method of punching wheel cores. The processing method of the punching wheel cores adopts the process technology of punching and compressing steel tubes or waste steel tubes in hot pressure dies and cold pressure dies to replace the original processing method of cast metal iron pieces. The processing method has the advantages of environmental protection and no pollution, high product intensity and long service life.

Description

technical field [0001] The invention relates to the field of processing wheel cores of front and rear wheels of various transport vehicles, lifting vehicles, flatbed vehicles and elevators, and in particular provides a processing method for stamping wheel cores. Background technique [0002] Under the prior art, the front and rear rolling wheels of manual trucks are generally processed by casting, but the wheel core produced by this method is not only weak in strength, but also difficult to process and high in cost. The material is generally cast iron, but its The weight of the wheel core is greater than that of the steel core, which is costly and not environmentally friendly. Contents of the invention [0003] A processing method for stamping wheel cores of the present invention uses various steel pipes as raw materials, and adopts the stamping and shrinking processing technology of hot pressure molds and cold pressure molds, which can produce wheel cores with high servic...
