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 a

Embodiment 1

[0033] Embodiment 1, with reference to figure 1 , 3 .

[0034] In the present invention, the round wool is used as the raw material. Firstly, the round wool is treated with a phosphate film surface treatment, and then the wool after the surface treatment of the phosphate film is fine-drawn and sized to be a round finished material. After fine-drawing and sizing, The disc round finished material is cut into a single plate mold adjustment seat material 10; then the following cold extrusion processing is also provided:

[0035] A. Upsetting an arc angle at one end of the material, and then through one to three cold headings to gradually increase the radius of the arc angle, and then cold heading this end into a flat plate for the plate mold adjustment seat The blank shape of the part, when the blank shape of the flat plate part is formed by cold heading, the length of the plate mold adjustment seat is shortened,

[0036] B. For the other end of the material, three to five hole...

Embodiment 2

[0045] Embodiment 2, with reference to figure 2 , 3 .

[0046] In this embodiment, the cold extrusion treatment A and the cold extrusion treatment B are carried out in corresponding stations according to the following sequence of stations. figure 2 , the reference numbers are the same as figure 1 The same means the same meaning.

[0047] The first station: level the front end 11b of the material, and upset the arc angle 12b at the rear end of the material to elongate the total length of the material; the reference number 1b is the plate mold adjustment seat material after the first station is completed .

[0048] The second station: the rear end of the material is upset on the basis of the first station to form an arc angle 21b with a larger radius to elongate the total length of the material; the reference number 2b is the plate after the second station Die adjustment seat material.

[0049] The third station: Turn the material over 180°, cold extrude the material, cold...

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. [0003] 1. Single-station col...
