Description
Technical Field
[0001] This utility model relates to the field of press technology, specifically to a punch mounting structure for a processing press. Background Technology
[0002] Presses are widely used in processes such as cutting, punching, blanking, bending, riveting, and forming. When processing forgings with a press, if the bottom of the forging is not flat enough, the forging is prone to slippage due to uneven force on the bottom surface. Furthermore, depending on the material and processing method, the force applied to the forging by the press needs to be sufficiently precise to improve the success rate of forging processing.
[0003] Currently, existing presses typically require different punches to process different products to meet varying production needs. However, the disassembly and assembly of existing punches often necessitate the use of numerous bolts to secure them and eliminate gaps, causing inconvenience for operators and reducing punch replacement efficiency. Therefore, this paper proposes a punch mounting structure for processing presses. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Please see Figure 1-4 This utility model provides a technical solution: a punch mounting structure for a processing press, including a body 1, a hydraulic cylinder 2, a piston rod 3, a punch body 4, and a connecting seat 5. The upper end of the body 1 is fixedly connected to the hydraulic cylinder 2, and the lower end of the hydraulic cylinder 2 is provided with a slidably connected piston rod 3. The lower end of the piston rod 3 is fixedly connected to the connecting seat 5. The upper end of the connecting seat 5 is fixedly connected to the end of the piston rod 3, and the lower end of the connecting seat 5 is detachably connected to the punch body 4. The punch body 4 includes a top plate 6, a punch 7, a locking bolt 8, and a locking tongue 9. The top plate 6 is fixedly installed on the top of the punch 7. The upper surface of the top plate 6 is provided with an embedding groove 10, the inner wall of the embedding groove 10 is provided with a locking tongue 9, and the side wall of the top plate 6 is provided with a threaded locking bolt 8.
[0023] In a further improvement, the connecting seat 5 is plugged into the embedded groove 10, and a fixing groove 11 is provided on the side wall of the connecting seat 5. By providing a fixing groove 11 on the side wall of the connecting seat 5, it is convenient to engage with the locking tongue 9 on the inner side of the top plate 6, thereby improving the convenience and stability of the connection between the punch body 4 and the connecting seat 5.
[0024] In a further improvement, the fixing groove 11 is located at the corner of the connecting seat 5, and the fixing groove 11 is distributed in an inclined manner. By providing the fixing groove 11 in an inclined manner at the corner of the connecting seat 5, it is convenient to connect with the locking tongue 9, thereby improving the stability of the connection between the connecting seat 5 and the top plate 6.
[0025] In a further improvement, the locking tongue 9 is embedded in the inner wall of the embedding groove 10. One end of the locking tongue 9 is rotatably connected to the top plate 6, and the other end of the locking tongue 9 is in contact with the end of the locking bolt 8. By making one end of the locking tongue 9 rotatably connected to the top plate 6 and the other end in contact with the locking bolt 8, it is convenient for the locking tongue 9 to rotate and push outward when the locking bolt 8 is turned, so as to connect with the fixing groove 11 on the side wall of the connecting seat 5.
[0026] In a further improvement, a rotating pin 13 is provided at the connection between the locking tongue 9 and the top plate 6, and a torsion spring 14 is provided at the connection between the rotating pin 13 and the locking tongue 9. By providing a rotating pin 13 with a torsion spring 14 at the connection between the locking tongue 9 and the top plate 6, the locking tongue 9 can automatically rebound, improving the ease of disassembling the punch body 4.
[0027] Specifically, the outer wall of the locking tongue 9 is provided with inclined wedge-shaped surfaces 12, which are slidably connected to the fixing groove 11. By providing wedge-shaped surfaces 12 on the outer wall of the locking tongue 9, it is convenient to press downward when the locking tongue 9 is embedded in the fixing groove 11, thereby eliminating the gap between the connecting seat 5 and the punch body 4 and improving the working stability of the press punch 7.
[0028] In use, the punch body 4 is placed at the lower end of the piston rod 3, the embedding groove 10 on the upper surface of the top plate 6 is aligned with the connecting seat 5 at the lower end of the movable rod, the flow direction of the hydraulic fluid in the hydraulic cylinder 2 is controlled, the piston rod 3 is pushed downward, so that the connecting seat 5 is inserted into the embedding groove 10, and the locking bolt 8 on the side wall of the top plate 6 is tightened with a tool. The locking bolt 8 pushes the locking tongue 9 outward and pushes the locking tongue 9 into the fixing groove 11 on the side wall of the connecting seat 5. During the translation process, the wedge-shaped surface 12 on the side wall of the locking tongue 9 improves the tightness of the connection between the connecting seat 5 and the top block, effectively avoiding the formation of voids at the connection between the connecting seat 5 and the punch body 4, and improving the convenience of installation.
[0029] The problem solved by this utility model is that existing presses often require different punches to be replaced when processing different products to meet different production needs. However, existing punches often require a large number of bolts for fixing during disassembly and assembly to eliminate gaps in the connection, which brings inconvenience to the operator when replacing the punch and reduces the efficiency of punch replacement. This utility model uses a machine body 1, hydraulic cylinder 2, piston rod 3, punch body 4 and connecting seat 5 to form a press punch 7 installation structure, which facilitates quick replacement of the punch body 4 and improves the convenience of disassembly and assembly operations for operators. By providing a ring-shaped fixed groove 11 on the side wall of the connecting seat 5 and a locking tongue 9 rotatably connected to the inner wall of the top plate 6, and cooperating with the locking bolt 8 threaded to the side wall of the top plate 6, it is easy to push the locking tongue 9 into the fixed groove 11, thereby improving the stability of the connection between the top plate 6 and the connecting seat 5.
