Novel production method of positioning block

Abstract

The invention discloses a novel production method of a positioning block. The novel production method adopts the technical scheme that the novel production method comprises the following production steps of (1) designing a cold drawing die according to the size of the cross section of the positioning block; (2) plastically deforming a steel bar into structural steel with a bulge or a groove through the cold drawing die by adopting a cold drawing process; (3) manually drawing a marking line on the to-be-cut part of the structural steel, fixing the structural steel to a cutting jig, wherein themarking line is exposed to the fixed part of the cutting jig, and cutting the structural steel into a plurality of steel blocks; and (4) machining the steel blocks in the step (3), and performing heattreatment so as to prepare the positioning block. According to the novel production method, the processing cycle is obviously shortened, the investment of manpower and equipment is reduced, the service life of the cold drawing die is long, the investment of the cold drawing die is lower than that of CNC equipment, real production shows that multi-time cutting is realized with one-time clamping, the comprehensive cost of the positioning block produced by adopting the process is less than that of the prior art by 50%, and economic benefits are obviously increased.

Description

technical field [0001] The invention relates to the field of mechanical processing technology, in particular to a high-efficiency and low-cost mold frame positioning block production technology. Background technique [0002] The mass production of industrial products and the development of new products are inseparable from the mold base positioning block. The high consistency, high productivity, high precision, high complexity, low energy consumption, and low Consumables make the mold industry more and more important in the manufacturing industry. As products are updated faster and faster, new products are emerging and new technologies are changing with each passing day, the scope of use of mold bases or molds has become wider and wider. The demand for frame positioning blocks is also increasing. [0003] Refer to the attached figure 1 , The mold frame positioning block generally includes a first positioning block with a protrusion and a second positioning block with a gro...

Problems solved by technology

[0003] Refer to the attached figure 1 , The mold frame positioning block generally includes a first positioning block with a protrusion and a second positioning block with a groove, and the protrusion and the groove cooperate with each other. The production of the first positioning block and the second positioning block in the prior art The process is roughly that, firstly, the steel plate is directly cut into pieces of steel blocks, and then the protrusions or grooves are processed by the CNC milling machine, and then the drilling, heat treatment and subsequent machining operations are carried out. The disadvantage of this production process is that Many processes, large waste of steel materials, long processing cycle and high cost
