The U-shaped steel bracket cable is a reliable connecting fastener provided by the U-shaped steel bracket. The U-shaped steel lap length is generally 400mm (different requirements of different drawings), the manufacturing process is simple, and the installation operation is convenient. U-shaped steel bracket cable is used as the positioning of U-shaped steel bracket. It requires high force, safety and stability, and is durable and durable. The equipment can be processed and manufactured to meet the requirements, and it has the advantages of material saving, stable molding, high processing efficiency and low investment. High efficiency and other advantages. Using a processing machine specializing in the manufacture of U-shaped steel cable, the cable can be processed to save 20% of material, improve its stability, easy to install, and good fastening performance to improve working resistance, so as to meet U-shaped steel bracket connection requirements. The processing machine includes a frame, a forming mold, a forming hydraulic jack, a demoulding hydraulic jack and an intermediate frequency heating device. [1-2]

Product introduction editor
U-shaped steel bracket cable is used as a U-shaped steel bracket connecting component, which requires high force, safety, stability, durability, safety and reliability.
U-shaped steel bracket cable
Improve the service life of roadways, reduce the maintenance rate of roadways, reduce the occurrence of safety accidents, and ensure the safe production of coal mines. [3]
Technical requirements editor
1) The cable should meet the corresponding standards set by the customer and press
U-shaped steel bracket cable
Manufactured in accordance with drawings and technical documents approved by the prescribed procedures.
2) The parts of the cable must have good interchangeability, and the bolts should be directly mounted on the cable board.
3) The surface of the cable must not have defects such as cracks, burrs and flash. [1-2]
Cable board
1) The material of the cable board is Q345 low carbon steel which is not lower than the mechanical properties of the U-shaped bracket steel;
2) The allowable error of the formed cable board thickness is ±0.5mm, and the width tolerance is ±0.2mm. The allowable deviation of the bolt hole pitch is ±1mm. [3]
Cable bolt
1) The cable bolts shall be made of round steel corresponding to the U-shaped steel material.
2) The bolt specification is M24 and the length is 35mm. The basic thread size should meet the requirements of GB/T96. The tolerance should meet the requirements of GB/T197 with an accuracy of 8g. [3]
Cable wire hole
The wire hole of the cable is the through hole of M24. The basic size of the thread should meet the requirements of GB/T96. The tolerance should meet the requirements of GB/T197 with an accuracy of 8g. [3]

U-shaped steel bracket limit cable used now, found in use
U-shaped steel bracket cable
Inconvenient operation, when the deformation of the bracket is severe, the cable breakage fails, the manufacturing process is complicated, the materials are uneconomical, and the U-shaped steel is long (400mm-500mm). Aiming at the defects of the positioning cable, a safe, reliable and economical U-shaped steel bracket cable has been developed. [3]

Processing step editing
The method of processing the cable includes the processes of blanking, hot press forming, drilling on the drilling machine, tapping and the like. Its features include the following steps:
1) Material selection. 16M or 20M16×80 steel plate;
2) Unloading. The 25U card cable is 460mm long and the 29U card cable is 480mm long.
3) Hot rolling. The steel plate is heated to 1000-1200 ° C for hot rolling forming;
4) Punch tapping. Make a 22.5mm hole on each side of the cable, and then use the wire tap to process the M24 thread with M24×35 bolts.
