[0002] See also Figure 1 As shown, when the lower end of the existing round rod is compressed and squared, since the traditional square pressing tooling uses a fixed method to fix the lower end of the round rod, the excess will stretch and support when the round rod is compressed and squared, resulting in a high rate of workpiece damage and scrap. Utility Model Content

[0003] In view of the defects existing in the prior art, the purpose of the utility model is to provide a square pressing tool, which uses an elastic connection method to fix the lower end of the round rod. When the round rod is compressed, the positioning block can be displaced downward by force, which can effectively release deformation and reduce damage to the workpiece.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is: a square pressing tool, including a horizontally arranged support plate, a square pressing mold and a fixed plate; the square pressing mold is arranged on the support plate, and is used to compress the round rod into a square; the fixed plate is arranged under the support plate and is connected to the support plate through a spring.

[0005] A further improvement is that a limit block is provided at the connection between the support plate and the spring.

[0006] A further improvement is that a limiting boss is provided at the upper end of the limiting block.

[0007] A further improvement is that a positioning block for positioning the end of the round rod is arranged on the support plate, and the shape of the positioning block is adapted to the shape of the round rod after being compressed and squared.

[0008] A further improvement is that the square pressing die comprises a plurality of extrusion blocks, and when the square pressing die compresses the round rod into a square shape, the extrusion surface of each extrusion block forms an extrusion cavity.

[0009] A further improvement is that the square pressing die comprises four extrusion blocks with the same structure, the cross-section of the extrusion blocks is fan-shaped, and the inner edge of the fan-shaped extrusion surface is a straight line.

[0010] A further improvement is that two adjacent extrusion blocks are fixedly arranged on the support plate, and the other two extrusion blocks can translate and extrude the round rod under the drive of an external driving mechanism.

[0011] A further improvement is that: the support plate is provided with a guide slot adapted to the movable extrusion block.

[0012] The beneficial effects of the utility model are:

[0013] 1. The lower end of the round rod is fixed by elastic connection. When the round rod is compressed, the positioning block can be deflected downward by force, which can effectively release deformation and reduce damage to the workpiece.

[0014] 2. In the present invention, a limit block is added to ensure that the positioning size is fixed. BRIEF DESCRIPTION OF THE DRAWINGS
