Problems solved by technology

Bending machines on the market are expensive, and most of them are machines for bending plates, or machines for bending pipes with larger diameters
The diameter of the tension clamp body is generally around 20MM-55MM, and the pipe diameter is small. It is necessary to ask a professional manufacturer to customize the processed product, and the price of the customized machine is more expensive. Secondly, the tension clamp body has different design requirements. The pipe diameter specifications of the tension clamp body are different. Different pipe diameter specifications need to be customized and replaced with a complete set of mold sets. The mold processing cost itself is high, and different models need to design and customize a complete set of mold sets, which is very expensive. In addition, due to the strong professionalism of the machine, when replacing a complete set of molds, it is necessary to ask the technicians of the bending machine manufacturer or the experienced technical masters of our factory to replace them, which will undoubtedly further increase the production cost of the enterprise
All in all, the production cost of the traditional bending machine to process the main body of the tension clamp is high. What kind of processing method should be used to realize the bending and forming of the main body of the tension clamp at low cost is a technical problem that the power fittings manufacturing industry needs to solve urgently

Embodiment 1

[0061] A method for bending and forming a tension clamp body, comprising the following steps:

[0062] a. Place the strain clamp body 1 on the workbench 21 in a posture of "one end high and one end low", and keep this posture fixed;

[0063] b. Give a bending support point at the place where the strain clamp body 1 needs to be bent; figure 1 A in indicates the bending support point;

[0064] c. The stamping die of the press 2 presses the high position of the tension clamp body 1 vertically downward slowly;

[0065] d. By controlling the vertical downward movement stroke of the stamping die to meet the bending requirements of the strain clamp body 1 with different bending angle requirements.

[0066] Wherein, in step c, the stamping die is in contact with the tension clamp body 1 in the form of rolling. Rolling while pressing the stamping die can prevent the product from being damaged due to local stress that cannot be released. The vertical downward movement speed of the ...

Embodiment 3

[0084] The present embodiment is based on Embodiment 2. The barrel bracket assembly 32 of the present embodiment includes a high barrel bracket 321 and a short barrel bracket 321. The head of the barrel bracket 321 is provided with a socket 322, and the barrel bracket 321 is fixed on On the base plate 6, the base plate 6 is fixed on the workbench 21, and the hollow gun barrel 31 with a T-shaped cross section passes through the socket 322 and is supported on the two gun barrel brackets 321, and one side of the gun barrel is provided with a lock for the hollow gun barrel 31. The locking piece 33 tightly on the gun barrel bracket 321 utilizes the locking piece to firmly fix the hollow gun barrel on the gun barrel bracket assembly; wherein the locking piece 33 is a screw rod 331 with a handle. The barrel support 321 is provided with a threaded through hole matching with the screw rod 331 . The locking member has a simple structural design, is easy to implement, and is easy to oper...

Abstract

The invention discloses a strain clamp body bending forming method and a gun barrel type bending tool thereof, belongs to the technical field of electric power fitting production and machining, and solves the problem of high machining cost of a traditional strain clamp body. A strain clamp is fixed in the posture that one end is high and the other end is low, and then bent and formed in cooperation with a method for controlling the vertical stroke of a press machine. The gun barrel type bending tool is designed in combination with the method. The strain clamp body bending forming method and the gun barrel type bending tool thereof are ingenious and novel in concept, the conventional bending thought is broken through, the production cost is reduced to be lower than 30% of the original production cost, bending forming of a strain clamp body is completed with very low cost, very low labor intensity, high efficiency and high quality, and considerable economic value is created for enterprises.

Description

technical field [0001] The invention belongs to the technical field of electric power fittings production, manufacturing and processing. Specifically, it relates to a low production cost, simple operation steps, strong universal type, high pass rate of one-time processing of products, high quality of processed products, high production efficiency and practicality. A strong tension-resistant clamp body bending forming method and barrel-type bending tooling. Background technique [0002] Tension clamp refers to the hardware used to fix the wire to bear the tension of the wire and hang the wire to the tension string or tower. According to the structure and installation method, the strain clamps are mainly divided into compression type strain clamps and bolt type strain clamps. Compression strain clamps are widely used because the clamping force is much better than that of bolt strain clamps. The authorized announcement number is CN102255269B, the authorized announcement date ...
