Description

Technical Field

[0001] This utility model relates to the field of press technology, specifically to a press punching slide adjustment mechanism. Background Technology

[0002] A press, also known as a stamping press or punch press, is an important piece of equipment widely used in industrial manufacturing. A press uses an electric motor to drive a flywheel, which in turn drives a crank-connecting rod mechanism via a clutch and transmission gears, causing the slide to move up and down. During processing, the sheet metal is directly subjected to deformation forces and deformed within the die, resulting in product parts with specific shapes, dimensions, and properties. A press generally consists of a worktable, four columns fixed to the worktable, and a stamping slide that reciprocates along the columns. When the stamping slide moves downwards, it works in conjunction with the die on the worktable to stamp and deform the workpiece.

[0003] Because of the assembly gap, the stamping slide also needs to be finely adjusted in the horizontal and vertical directions by the adjustment mechanism to ensure the fitting accuracy between the stamping slide and the mold and improve the quality of the stamped parts. Utility Model Content

[0004] In view of the above-mentioned technical deficiencies, the purpose of this utility model is to provide a press punching slide adjustment mechanism to achieve precise adjustment of the punching slide in the horizontal and vertical directions, so as to improve the accuracy and stability of the punching operation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The present invention provides a press punching slide adjustment mechanism, comprising:

[0006] Four adjusting seats are slidably mounted on the four columns of the press; each adjusting seat has an installation cavity, and the four corners of the punching slide near the four columns are located in the installation cavities of the four adjusting seats respectively.

[0007] Each of the adjustment seats is provided with two horizontal adjustment units and two vertical adjustment units. The two horizontal adjustment units are used to adjust the gap between the stamping slider and the inner wall of the mounting cavity in the horizontal direction, and the gap adjustment directions of the two horizontal adjustment units are perpendicular. The two vertical adjustment units are used to adjust the gap between the stamping slider and the inner wall of the mounting cavity in the vertical direction, and the gap adjustment directions of the two vertical adjustment units are opposite.

[0008] Preferably, the two horizontal adjustment units are a first adjustment unit and a second adjustment unit, the first adjustment unit includes a backing plate and a first bolt threaded onto the adjustment seat, the backing plate is located between the inner wall of the mounting cavity and the side wall of the stamping slider, and one end of the first bolt abuts against the side of the backing plate away from the stamping slider.

[0009] Preferably, the abutment plate is detachably universally fitted with the first bolt.

[0010] Preferably, the abutment plate has a spherical groove, and the end of the first bolt near the abutment plate has a hemispherical head that mates with the spherical groove.

[0011] Preferably, a sleeve is fixed to one end of the hemispherical head near the first bolt, and the first bolt is inserted into the sleeve.

[0012] Preferably, the adjusting seat includes a guide sleeve and a base fixed on the guide sleeve. The guide sleeve is sleeved on the column, the mounting cavity is opened in the base, and a reinforcing rib is provided between the guide sleeve and the base.

[0013] Preferably, two adjacent adjustment seats are fixedly connected by a connecting plate.

[0014] The beneficial effects of this utility model are as follows:

[0015] This invention features four adjustment seats, each with two horizontal and two vertical adjustment units. These allow for adjustment of the horizontal and vertical positions of the four corners of the stamping slide block in three-dimensional space, resulting in more precise mold fitting under the stamping slide block and improved stamping accuracy and stability. The universal joint between the abutment plate and the first bolt allows for more flexible adjustment. The clamping force of the first bolt is effectively transmitted to the abutment plate through the fit between the hemispherical head and the spherical groove, ensuring the abutment plate firmly presses against the stamping slide block.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Example 1:

[0026] like Figures 1 to 5 As shown, Embodiment 1 of this utility model provides a press press slide adjustment mechanism, including four adjustment seats 5. Each adjustment seat 5 includes a guide sleeve 18 and a base 19 welded to the side wall of the guide sleeve 18. The guide sleeves 18 of the four adjustment seats 5 are respectively tightly slidably fitted onto the four columns 2 on the press worktable 1, ensuring that the adjustment seat 5 can slide smoothly along the columns 2. The base 19 has mounting cavities 6 inside to accommodate the corners of the press slide 3. Figure 3 As shown, the four corners of the stamping slider 3 are located in the mounting cavities 6 of the four bases 19. To enhance structural strength, multiple reinforcing ribs 20 are provided between the guide sleeve 18 and the base 19.

[0027] To adjust the horizontal and vertical alignment of the stamping slide block 3 and align it with the mold 4 on the worktable 1, this invention installs two horizontal adjustment units and two vertical adjustment units on each adjustment seat 5. For ease of distinction, in this embodiment, the two horizontal adjustment units are referred to as the first adjustment unit 7 and the second adjustment unit 8, and the two vertical adjustment units are referred to as the third adjustment unit 9 and the fourth adjustment unit 10. The first adjustment unit 7, the second adjustment unit 8, the third adjustment unit 9, and the fourth adjustment unit 10 have the same structure but different installation positions, thus their functions differ. Figure 3 and Figure 4As shown, taking the first adjusting unit 7 as an example, it includes a backing plate 11 and a first bolt 12 threaded onto the adjusting seat 5. The backing plate 11 is located between the inner wall of the mounting cavity 6 and the side wall of the stamping slider 3. By rotating the first bolt 12, its end can press against the backing plate 11, causing the backing plate 11 to press against the stamping slider 3, thereby adjusting the horizontal gap between the stamping slider 3 and the inner wall of the mounting cavity 6. The backing plates 11 of the first adjusting unit 7 and the second adjusting unit 8 are located in different positions, respectively pressing against the two side walls of one corner of the stamping slider 3. That is, the adjustment directions of the first adjusting unit 7 and the second adjusting unit 8 for adjusting the gap between the stamping slider 3 and the inner wall of the mounting cavity 6 are perpendicular. By adjusting the first adjusting unit 7 and the second adjusting unit 8 on the four adjusting seats 5, the position of the stamping slider 3 on the horizontal plane can be finely adjusted.

[0028] The third adjustment unit 9 and the fourth adjustment unit 10 are located on the upper and lower sides of the stamping slider 3, respectively, and are used to adjust the gap between the top and bottom of the stamping slider 3 and the inner wall of the mounting cavity 6, that is, to adjust the gap between the stamping slider 3 and the inner wall of the mounting cavity 6 in the vertical direction. The gap adjustment directions are opposite. The third adjustment unit 9 can finely adjust the stamping slider 3 downward, while the fourth adjustment unit 10 can finely adjust the stamping slider 3 upward, thereby realizing the position adjustment of the stamping slider 3 in the vertical direction.

[0029] Example 2:

[0030] Based on Embodiment 1, to achieve more flexible adjustment, a detachable universal joint is used between the abutment plate 11 and the first bolt 12. For more precise adjustment, such as... Figure 5 As shown, a spherical groove 15 is formed on the abutment plate 11, and a hemispherical head 16 that fits tightly with the spherical groove 15 is provided at the end of the first bolt 12 near the abutment plate 11. This design allows the abutment plate 11 to be slightly deflected as needed during adjustment, ensuring optimal contact with the side wall of the stamping slider 3. In addition, a sleeve 17 is fixed at the end of the hemispherical head 16 near the first bolt 12, and the first bolt 12 is inserted into the sleeve 17, further enhancing the stability of the structure and the flexibility of adjustment, while also facilitating disassembly and installation.

[0031] Example 3:

[0032] To enhance the stability of the entire adjustment mechanism, the bases 19 of two adjacent adjustment seats 5 are fixedly connected by a connecting plate 21. The connecting plate 21 is fixed to the base 19 by bolts, so that the four adjustment seats 5 form an integral frame, effectively resisting the lateral force during the stamping process.

[0033] Working principle: When fine-tuning the position of the stamping slider 3 is required, first loosen all the bolts on the adjusting seats 5 slightly to loosen the gap between the abutment plate 11 and the stamping slider 3. Then, adjust the fourth adjusting unit 10 among the four adjusting seats 5 by rotating the fourth bolt 14 in the fourth adjusting unit 10, so that the four abutments 11 respectively abut against the bottom of the four corners of the stamping slider 3, thereby leveling the bottom surface of the stamping slider 3. Next, rotate the first bolt 12 of the first adjusting unit 7 and the second bolt of the second adjusting unit 8 to push the abutment plate 11 to move the stamping slider 3 slightly on the horizontal plane, thereby aligning the position of the stamping slider 3. Finally, tighten the third bolt 13 in the upper third adjusting unit 9 to press the abutment plate 11 firmly against the stamping slider 3, completing the fine-tuning of the stamping slider 3.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
