Multi-station cold heading manufacturing method for plate die adjusting seat blank

Abstract

The invention provides a multi-station cold heading manufacturing method for a plate die adjusting seat blank. Disc wool is used as a raw material. The method comprises the following steps of: performing phosphate skin membrane surface treatment on the disc wool, performing fine drawing and sizing on the wool subjected to the phosphate skin membrane surface treatment to obtain a disc finished product material, and shearing the disc finished product material obtained after fine drawing and sizing into single plate die adjusting seat pieces; and performing cold extrusion treatment, wherein the cold extrusion treatment is performed in corresponding stations. Straight bars and broken materials are replaced by adopting the disc material, so the requirement of multi-station cold heading continuous production can be completed, and the loss of stub bars and tails is reduced; and meanwhile, after multi-station cold heading one-time molding is adopted, the lathe allowance of a plate die adjusting seat is reduced, and the loss of raw materials is reduced by 30 percent, so the cost is reduced.

Description

technical field [0001] The invention relates to a cold heading manufacturing method of a plate mold adjusting seat blank. Background technique [0002] The formwork adjustment seat is widely used in the construction industry. The main body of the formwork adjustment seat is a cylinder with an axial threaded blind hole. The formwork adjustment seat is a hexagonal flat plate at the end of the cylinder without holes. shape. Nowadays, with the continuous progress of domestic and foreign industrial economy and the rapid development of the construction industry, the demand for formwork adjustment seats is increasing. At present, the manufacturing method of the plate formwork adjustment seat mostly adopts single-station cold heading or hot heading production. The produced plate formwork adjustment seat has unstable strength such as tensile force, complex processing, high energy consumption, low production efficiency, and low cost. advanced defects.

AI Technical Summary

Problems solved by technology

At present, the manufacturing method of the plate formwork adjustment seat mostly adopts single-station cold heading or hot heading production. The produced plate formwork adjustment seat has unstable strength such as tensile force, complex processing, high energy consumption, low production efficiency, and low cost. advanced defects

[0003] 1. Single-station cold heading or hot heading production is used, which cannot meet the requirements of multi-station continuous production. The plane of the base, the inner hole and the end surface all require large-area finishing machining and large punching machines. There are many procedures, complex processing, and production. High cost and low efficiency

The daily output of a single device is only 4000PCS, the market demand is in short supply, and the manpower and material resources invested are too large, which does not meet the national policy requirements for energy conservation and emission reduction

[0004] 2. Single-station cold heading is adopted, and the crystal phase structure of the product after production is not tightly arranged, which may easily cause insufficient strength such as tensile strength and cause product cracking or cracking and other undesirable phenomena

[0005] 3. The production of straight bar or broken material cannot meet the requirements of continuous production, and more waste such as material head and material tail will be generated, and subsequent lathe processing with multiple processes and large areas will be required, resulting in waste of materials , the material cost increases

[0006] 4. The follow-up lathe has a large amount of processing. Due to the influence of equipment, tools and human factors, it is easy to produce deviations and instability in size and roughness. Finally, the requirements for finished products cannot meet the specified design and use requirements.
