DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0038] The following describes an embodiment of the utility model based on its overall structure.

[0039] Embodiment 1:

[0040] A punch press that is easy to adjust the punch press die, such as Figure 1-Figure 4As shown, it includes a body 1, an upper mold base 4 and a lower mold base 5. The top of the lower mold base 5 is fixedly connected to the lower mold 7 through a mounting mechanism 9. Both sides of the lower mold base 5 are provided with a plurality of first mounting grooves 6. The lower mold 7 includes a mold body 701. Both sides of the mold body 701 are provided with second mounting grooves 703. The first mounting groove 6 is opposite to the second mounting groove 703. A threaded rod 904 can be slidably connected in the second mounting groove 703. A threaded groove 702 is provided at the end of the second mounting groove 703. The internal thread of the threaded groove 702 is connected to a threaded block 901. The threaded block 90 1 is provided with an internal thread groove 903, which is screwed with the threaded rod 904, a clamping block 905 is provided at the bottom of the threaded rod 904, the first installation groove 6 is slidably connected with the clamping block 905, a clamping groove 8 is provided at the bottom of the mold body 701, the clamping groove 8 is engaged with the clamping block 905, the first installation groove 6 and the second installation groove 703 are relatively designed, and the clamping mechanism of the clamping block 905 and the clamping groove 8 makes the installation and disassembly process of the mold more convenient and efficient. This design significantly reduces the time and labor cost required for replacing the mold and improves the production efficiency.

[0041] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A rotating rod 902 is provided on the top of the threaded block 901, and the rotating rod 902 is used to rotate the threaded block 901. The rotating rod 902 provides an intuitive and easy-to-operate interface, allowing the staff to easily manually rotate the threaded block 901. This design simplifies the adjustment process, reduces the difficulty of operation, and improves work efficiency. Moreover, by rotating the rotating rod 902, the position of the threaded block 901 can be finely adjusted, thereby accurately controlling the installation position and tightening degree of the mold. This precise adjustment is crucial to ensuring the accuracy and quality of the stamping process.

[0042] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A hexagonal hole 906 is provided at the top of the threaded rod 904, and the hexagonal hole 906 is used to insert a hexagonal wrench. The design of the hexagonal hole 906 allows the staff to easily rotate the threaded rod 904 using a hexagonal wrench. This operation method is more labor-saving and accurate than directly rotating by hand, especially when a large torque needs to be applied or fine-tuning needs to be performed. The use of a hexagonal wrench can quickly complete the rotation operation of the threaded rod 904, thereby improving work efficiency. This is particularly obvious in situations where the threaded rod 904 needs to be frequently adjusted or tightened.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4The threaded rod 904 is used to adjust the height of the block 905 to ensure that the block 905 is inserted into the slot 8. The rotation of the threaded rod 904 can finely adjust the height of the block 905 to ensure that the block 905 can be accurately inserted into the slot 8. This precise adjustment is crucial to the installation accuracy and stability of the mold, which helps to ensure the accuracy of the stamping process and the quality of the product. Moreover, by adjusting the threaded rod 904, it can adapt to molds of different thicknesses or slots 8 of different depths, thereby improving the flexibility and versatility of the installation mechanism. This design allows the same set of installation mechanisms to be applicable to molds of various specifications, reducing the adjustment cost and time when changing molds.

The forward threaded connection means that when the thread block 901 is screwed into the thread groove 702, it will be gradually tightened in the direction of rotation. This design helps to enhance the stability of the connection and prevent loosening. The reverse threaded connection design allows the threaded rod 904 to move up and down relative to the internal thread groove 903 when rotating. This design not only facilitates the adjustment of the position of the threaded rod 904, but also makes it easier to operate when disassembly is required.

[0045] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 There are multiple mounting mechanisms 9, and the multiple mounting mechanisms 9 are divided into two groups, and each group is provided with four. The two groups of mounting mechanisms 9 are mirror-set along the central axis of the lower mold 7. By mirror-setting the mounting mechanisms 9 on both sides of the lower mold 7, it can be ensured that the lower mold 7 is subjected to uniform force during the installation process, thereby maintaining better stability and balance. This design helps to reduce vibration and deviation during the stamping process and improve product quality. Moreover, the mirror-setting mounting mechanisms 9 can ensure that the installation positions and fastening forces on both sides remain consistent, thereby improving the installation accuracy, which is particularly important for stamping processes that require high-precision positioning.

[0046] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A cylinder seat 2 is provided on the top of the machine body 1, and a cylinder 3 is fixedly connected to the bottom of the cylinder seat 2. The cylinder 3 is fixed to the top of the machine body through the cylinder seat 2. This design ensures the stability and reliability of the cylinder 3, and the cylinder seat 2 provides a solid installation foundation for the cylinder 3, which helps to reduce the vibration and displacement that may be generated by the cylinder 3 during operation, thereby maintaining the smooth operation of the mechanical system.

[0047] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 The output end of the cylinder 3 is provided with an upper die seat 4, the bottom of the upper die seat 4 is detachably connected to the upper die through a mounting mechanism 9, the lower die 7 is matched with the upper die, and the output end of the cylinder 3 is directly connected to the upper die seat 4. This design allows power to be directly and efficiently transmitted to the upper die, reducing the loss during power transmission and improving the stamping efficiency. Moreover, by directly connecting the output end of the cylinder 3 with the upper die seat 4, the structure of the entire stamping device is more compact, saving space, making the equipment lighter and easier to integrate into various production lines.

[0048] Embodiment 2:

[0049] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A plurality of expansion slots 10 are provided on both sides of the body 1, and protective blocks can be plugged into the expansion slots 10.

[0052] Next, the lower mold 7 is accurately placed on the lower mold base 5, ensuring that the second mounting groove 703 of the mold body 701 is completely aligned with the first mounting groove 6 of the lower mold base 5, and then, by carefully adjusting the positions of the threaded rod 904 and the threaded block 901, the clamping block 905 reaches a moderate height, and finally, the clamping block 905 is firmly clamped into the clamping groove 8 at the bottom of the mold body 701 to ensure that the mold is firmly installed. The upper mold is installed on the upper mold base 4 using the same steps and methods;

[0053] After installation, carry out debugging and inspection work, turn on the punch press, perform preliminary punching tests, and carefully observe whether the mold can work normally and whether there is any looseness or offset. If problems are found, the position of the mold can be fine-tuned by adjusting the threaded rod 904 to ensure the accuracy and quality of the punching.
