Problems solved by technology

[0003] U-shaped bolts are non-standard parts. The shape is U-shaped, so they are also called U-shaped bolts. There are threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of automobiles. The way of the object is like a person riding on a horse, also known as a riding bolt. U-shaped bolts are widely used on automobile chassis. In the production process of U-shaped bolts, it is often necessary to blank and compress the blank. Simple, poor compression effect, affecting the production quality of bolts

Embodiment 1

[0025] refer to Figure 1-3 , a U-shaped bolt blanking and pressing device for an automobile chassis, comprising a workbench 10, the same gantry 16 is fixed by screws on both sides of the top outer wall of the workbench 10, and the top inner wall of the gantry 16 is fixed by screws. Cylinder 15, one end of the piston rod of hydraulic cylinder 15 is fixed with a fixed cylinder by a screw, and the inner wall of the fixed cylinder is slidably connected with a slide plate, the bottom outer wall of the slide plate is fixed with a connecting rod through a screw, and the bottom outer wall of the connecting rod is fixed with a compression pin through a screw. Plate 14, the bottom outer wall of the slide plate located on both sides of the connecting rod is fixed with a return spring by screws, and the bottom end of the return spring is connected with the bottom inner wall of the fixed cylinder.

[0026] In the present invention, the top outer wall of the workbench 10 is fixed with the ...

Embodiment 2

[0032] refer to figure 1 , a U-shaped bolt blanking and pressing device for an automobile chassis. Compared with Embodiment 1, this embodiment also includes that the four corners of the outer wall of the bottom of the workbench 10 are fixed with a buffer tube 9 by screws, and the inner wall of the buffer tube 9 Slidingly connected with piston 3, the bottom outer wall of piston 3 is welded with buffer rod 8, the outer wall of buffer rod 8 is sleeved with damping spring 4, and the bottom outer wall of buffer rod 8 is fixed with support plate 5 by screws.

[0033] During the stamping process, the device will vibrate violently, and the shock-absorbing spring 4 can have a good shock-absorbing effect, so as to avoid damage to the device itself due to excessive vibration.

Abstract

The invention discloses a U-shaped bolt feeding compressing device for an automobile chassis. The device comprises a workbench, wherein two sides of the outer wall of the top of the workbench are fixedly provided with a portal frame through screws, and the inner wall of the top of the portal frame is fixedly provided with a hydraulic cylinder through screws; one end of a piston rod of the hydraulic cylinder is fixedly provided with a fixed cylinder through screws, and the inner wall of the fixed cylinder is connected with a sliding plate in a sliding manner; the outer wall of the bottom of thesliding plate is fixedly provided with a connecting rod through screws, and the outer wall of the bottom of the connecting rod is fixedly provided with a compressing plate through screws; the outer walls of the bottoms, at two sides of the connecting rod, of the sliding plate are fixedly provided with return springs through screws; and the bottom ends of the return springs are connected to the inner wall of the bottom part of the fixed cylinder. The device avoids the waste of a blank, a motor works to drive a cam to rotate, and the cam rotates to drive the compressing plate to move up and down, and the compressing plate performs punch forming on the blank in a U-shaped groove, thus good punching effect is achieved, and the production quality of a bolt is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile chassis production, in particular to a U-shaped bolt blanking and pressing device for automobile chassis. Background technique [0002] The chassis of a car is composed of four parts: transmission system, driving system, steering system and braking system. Sports to ensure normal driving. [0003] U-shaped bolts are non-standard parts. The shape is U-shaped, so they are also called U-shaped bolts. There are threads at both ends that can be combined with nuts. They are mainly used to fix tubular objects such as water pipes or sheet objects such as leaf springs of automobiles. The way of the object is like a person riding on a horse, also known as a riding bolt. U-shaped bolts are widely used on automobile chassis. In the production process of U-shaped bolts, it is often necessary to blank and compress the blank. Simple, poor compression effect, affecting the production quality of bolts. Cont...
