Description

Technical Field

[0001] The utility model belongs to the field of bending machines, and in particular relates to a bending machine for processing U-shaped bolts. Background Art

[0002] U-bolts are named for their U-shaped shape. They have threads at both ends that can be combined with nuts. U-bolts are generally used in trucks to stabilize the chassis and frame of the vehicle. For example, leaf springs are connected by U-bolts. U-bolts are generally made of cold-drawn round steel as the raw material. Cold-drawn round steel has a smooth surface, high dimensional accuracy, and high mechanical properties. It is often used as the raw material to make U-bolts. After the raw material is cut into a certain length by a cutting machine, it needs to be bent by a bolt bending machine before entering the next process.

[0003] The patent application with announcement number CN220329669U discloses a bolt bending machine for U-bolt processing, including: a workbench and a bending model, a fixed block driven by an electric cylinder that can clamp the bolt raw material is provided on one side of the bending model, and positioning components are provided at both ends of the bolt raw material. A bending assembly driven by a hydraulic cylinder for bending the bolt raw material is provided on both sides of the fixed block on one side of the bolt raw material, and the bending assembly includes a U-shaped fixed block connected to the output end of the hydraulic cylinder and a bending roller connected to the U-shaped fixed block for longitudinal rotation. A limit baffle is fixed on the upper end of the U-shaped fixed block to prevent the bolt raw material from bending upward and bouncing during the bending process. The utility model can prevent the bolt raw material from deviating in the horizontal direction when bending, prevent the U-shaped bolt from having one end longer than the other after bending, and improve the qualified rate of U-shaped bolt bending; it can prevent the bolt raw material from falling off or bending upward and bouncing when bending, and improve the safety of the bending work.

[0004] However, the above technology has the following disadvantages when used:

[0005] The above-mentioned document, paragraph 0020, describes that “for precise placement, positioning components are provided at both ends of the bolt material, and the positioning components include an electric telescopic rod and a limit block connected to the output end of the electric telescopic rod for pushing one end of the bolt material. The limit block can push the bolt material at both ends of the bolt material under the push of the electric telescopic rod, so that the bolt material is accurately located between the bending model and the fixed block, preventing the U-shaped bolt from being longer at one end and shorter at the other end after bending, thereby improving the bending qualification rate of the U-shaped bolt”. Figure 1 It can be seen that the position of the bolt material needs to be adjusted through two limit blocks. Since the two limit blocks are driven by two electric telescopic rods respectively, the moving distances of the two limit blocks will be inconsistent, thereby reducing the accuracy of placing the bolt material.

[0006] Therefore, a bending machine for U-bolt processing is proposed to solve the above-mentioned drawbacks. Utility Model Content
