Fixed block special for bending machine

Abstract

The invention discloses a special fixing block for a twisting machine, which is characterized in that it comprises a T-shaped block structure arranged symmetrically as a whole, rectangular steps are symmetrically arranged on both sides of the T-shaped block structure, and a semi-submerged groove is opened on the top. The right side of the semi-sinking groove extends to the right end of the T-shaped block structure, and the left side of the groove has a semicircular surface with a diameter of 14 mm. There are three vertical threaded through holes on the center line of the bottom of the groove. There is a horizontal threaded hole on the left end face of the T-shaped block structure. The invention has the advantages of low cost, easy processing and forming, and long service life, and can ensure that when the twisting machine manufactures products, the positioning is accurate, the overall stability is good, the product quality is good, and the production efficiency is high, and it is suitable for mass production of the twisting and bending process of the fin evaporator production use.

Description

technical field [0001] The invention relates to the field of accessories for twisting machines, in particular to a special fixing block for twisting machines. Background technique [0002] The finned evaporator is an important pipeline component in a new type of high-efficiency energy-saving refrigerator, and its overall performance directly determines the overall use of the refrigerator. In the manufacturing process of the finned evaporator, the bent and formed pipe parts need to be bent and twisted to facilitate the subsequent fin insertion and positioning processing. During the vertical bending and twisting processing in the above-mentioned manufacturing process, the integrally formed pipe must be positioned and fixed, so twisting and fixing accessories are required to meet actual production needs. In the actual production process of ordinary torsion and bending fixing blocks, there are the following problems: 1. Single vertical threaded hole during continuous torsion be...

AI Technical Summary

Problems solved by technology

In the actual production process of ordinary torsion and bending fixing blocks, there are the following problems: 1. Single vertical threaded hole during continuous torsion bending production, the fixed torsion and bending part is easy to deviate, resulting in the size of the torsion bending product not meeting the standard; 2. There is no positioning on the side of the fixing block Holes, no positioning on the side after installation, resulting in easy displacement of the side of the twisted fixed block; 3. There is no arc transition area on the side end of the fixed block, and when the twisted hanging pipe is produced, indentations or scratches often appear in the twisted and bent area of ​​the pipe
