Description

A shearing device for automobile leaf spring production

Technical Field

The invention belongs to the technical field of automobile leaf spring production, and more specifically, particularly relates to a shearing device for automobile leaf spring production.

Background technique

Leaf spring is the most widely used elastic element in automobile suspension. It is an elastic beam of approximately equal strength composed of several alloy spring leaves of equal width but unequal length. A general leaf spring includes multiple spring leaves, clamps, and gaskets placed between the spring leaves. The lengths of each spring leaf are different, so the raw steel plate needs to be cut into predetermined lengths during processing.

For example, in the patent with application number: CN202321692143.4, a shearing device for producing automobile leaf springs is disclosed, comprising a frame and a shearing mechanism installed on the frame, the shearing mechanism comprising a bracket, four light rods vertically fixed between the bracket and the frame, a lifting slide movably mounted on the four light rods, a cutter fixed to the bottom end of the lifting slide, and a hydraulic cylinder fixed on the bracket and the hydraulic cylinder piston rod is connected to the top end of the lifting slide, and a clamping assembly is provided on the front and rear end surfaces of the lifting slide, the clamping assembly comprises a clamping plate, a plurality of connecting rods arranged on the top surface of the clamping plate and a spring mounted on the surface of the connecting rod. The utility model has a compact structure and novel design. When shearing is performed, the clamping plate and the spring move downward with the cutter, and the moving steel plate can be clamped and fixed at the clamping plate, so that the sheared steel plate will not move during shearing, thereby improving the stability of the device.

Based on the above, the inventors found that the shearing equipment currently used has the following problems:

1. Generally, the steel plate raw material is sheared by a shearing knife. During continuous shearing, the temperature of the shearing knife is too high, which affects the service life of the shearing knife;

2. Although some shearing equipment is equipped with a feeding structure, the feeding length cannot be automatically adjusted according to the production length of the automobile leaf spring;

3. When the shearing knife reaches the shearing position, it cannot start automatically and needs to be started manually by the worker, which increases the labor intensity of the worker.

In addition, the provision of the two positioning pins A plays a positioning role on the tool holder, so that the tool holder will rotate only when it is engaged with the two racks. When the two hydraulic cylinders move upward, the tool holder will not rotate.

2. In the present invention, when the two hydraulic cylinders drive the tool holder to move downward, the rubber sleeve is in close contact with the steel plate raw material under the action of the two supporting springs D. When the tool holder continues to move downward, the angle of the push frame changes, driving the steel plate raw material to move to the left, thereby realizing automatic feeding of the steel plate raw material;

In addition, when the shear knife cuts the steel plate raw material, the two locating pins B are inserted into the two locating grooves B, which limit the pushing frame. When the two hydraulic cylinders drive the tool seat to move upward, the two arc-shaped guide rods contact the L-shaped reset plate, which pushes the two arc-shaped guide rods, separating the two locating pins B from the two locating grooves B.

3. In the present invention, since the elastic force of the two support springs A is greater than the friction between the rubber sleeve and the steel plate raw material, when the left end of the steel plate raw material contacts the fixed-length support plate, the rubber sleeve and the steel plate raw material slide, causing the steel plate raw material to stop moving, making it convenient for the staff to appropriately adjust the installation position of the fixed-length support plate through the U-shaped handle, so as to facilitate cutting of different lengths;

In addition, when the steel plate raw material contacts the fixed-length support plate, the start switch is in a pressed state, realizing the automatic start of the two hydraulic cylinders.
