[0002] Springs are a common mechanical part, widely used in automobiles, home appliances, industrial equipment and other fields. Leaf springs are one of the common types, usually made of metal sheets through shearing, forming, heat treatment and other processes. With the development of industrialization, the production efficiency and quality requirements of springs are increasing, so efficient and accurate production equipment is needed to meet market demand. However, the existing shearing machines for leaf spring production still have the problem of not being able to quickly and accurately cut out the required length of steel plates, and not being able to make the cut steel plates fall down automatically.

[0003] Therefore, it is very necessary to invent a shearing machine for producing leaf springs. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a shearing machine for leaf spring production, so as to solve the problem that the existing shearing machine for leaf spring production still cannot quickly and accurately shear out the steel plate of the required length, and cannot make the sheared steel plate fall down automatically.

[0006] The downward pressure base includes a basic support block, a tightening block and a limit block, and the basic support block is slidably mounted on the guide column and fixedly mounted on the bottom end of the hydraulic push rod; the tightening block is fixedly mounted in the middle of the bottom of the basic support block, and the limit blocks are fixedly mounted on both sides of the bottom of the basic support block.

[0007] The guiding surface inside the lower shearing structure adopts a downwardly inclined inclined surface, and the shearing push rod adopts two sets of hydraulic push rods, and the shearing block adopts a steel metal block; a blade is provided on the top of the shearing block, and the shearing block slides in the vertical direction in accordance with the plane of the side of the lower base, and is used to shear and cut off the steel plate clamped between the lower base and the downward pressure base through the upward movement of the shearing block, and the cut and fallen steel plate will slide off the surface of the guiding surface to prevent it from remaining on the workbench surface for a long time and preventing it from affecting the next shearing.

[0008] The downward pressure base is a steel metal block as a whole, and the basic support block can move in the vertical direction through the drive of the hydraulic push rod. There is a gap between the clamping block and the limit block; there is a height difference between the clamping block and the limit block, and the bottom surface of the clamping block is higher than the bottom surface of the limit block.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] 1. The setting of the lower shearing structure of the utility model is used to shear and cut off the steel plate clamped between the lower base and the lower pressing base by moving the shear block upward, and the cut and dropped steel plate will slide off the surface of the guide surface to prevent it from remaining on the workbench surface for a long time and affecting the next shearing.

[0011] 2. The setting of the downward pressure base of the utility model has the following functions: ① Applying downward pressure: The downward pressure base applies downward pressure through the action of the hydraulic push rod. This pressure causes the steel plate between the shear block and the lower base to be compressed, ensuring the stability and accuracy of the steel plate during the shearing process; ② Positioning and supporting: The downward pressure base serves as the lower support point of the steel plate during the shearing process, and positions the relative position of the shear block and the sheared steel plate, which ensures the correct position of the steel plate during the shearing process and avoids shearing deviation or dislocation.
