Description

Technical Field

[0001] The utility model relates to the technical field related to explosion-proof valve sheets, in particular to a stamping die for explosion-proof valve sheets. Background Art

[0002] Explosion-proof valves are used in dust removal systems containing flammable gases or flammable substances. They can be used as pressure relief devices for explosive pipes or equipment. The diaphragm of the explosion-proof valve is usually calculated based on the operating pressure of the dust removal system and the content of flammable substances, and then the material, thickness and scratches are selected. The normal operation of the system must not be affected by improper selection. In the process of processing explosion-proof valve plates, stamping dies are required for forming. Stamping dies are a special process equipment that processes materials into parts in cold stamping.

[0003] However, in the process of closing the upper mold and the lower mold, the upper mold is directly pressed on the lower mold, and the buffering effect is poor. After long-term processing, the mold will produce greater wear and tear, affecting its service life. Therefore, this application provides a stamping mold for explosion-proof valve plates to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0022] 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. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 The utility model provides a technical solution: a stamping die for an explosion-proof valve sheet, comprising a base 1, a hydraulic cylinder 2 is installed above the base 1, a hydraulic rod 3 is installed above the hydraulic cylinder 2, and a top material block 4 is fixed above the hydraulic rod 3. The device does not require the staff to manually take out the explosion-proof valve sheet from the lower mold 9, which reduces the workload of the staff. The top material block 4 forms a lifting structure with the hydraulic cylinder 2 and the base 1. The top material block 4 is consistent with the shape of the lower mold 9. Turning on the switch of the hydraulic cylinder 2 drives the hydraulic rod 3 to rise, and the top material block 4 is lifted upward, so that the formed explosion-proof valve sheet is ejected. A fixing hole 5 is opened on the upper surface of the base 1, and a lower mold seat 6 is arranged above the base 1. The lower mold seat 6 is threadedly connected to the base 1 through a bolt 8. The inner side of the fixing hole 5 is threaded. The lower mold seat 6 is placed above the base 1 and the mounting hole 7 is aligned with the fixing hole 5. The lower mold seat 6 can be quickly fixed by tightening the bolt 8, and the installation method is relatively simple.

[0024] See also Figure 3-4 A mounting hole 7 is provided on the upper surface of the lower die seat 6, and a bolt 8 is passed through the upper surface of the mounting hole 7. A lower die 9 is installed on the upper surface of the lower die seat 6, and limiting sleeves 10 are fixed on both sides of the upper surface of the lower die seat 9; guide pillars 11 are fixed on both sides of the upper surface of the lower die seat 6, and a guide sleeve 12 is sleeved on the upper surface of the guide pillar 11, and an upper die seat 13 is fixed on the upper surface of the guide sleeve 12. The upper die seat 13 forms a sliding structure with the guide pillar 11 through the guide sleeve 12, and the inner diameter of the guide sleeve 12 coincides with the diameter of the guide pillar 11, thereby improving the stability of the upper die seat 13 during the lifting process;

[0025] See also Figure 4-5, an upper mold 14 is installed below the upper mold base 13, and limiting rods 15 are fixed on both sides of the lower side of the upper mold 14. The limiting rods 15 are symmetrically arranged on the central axis of the upper mold 14, and the limiting rods 15 are arranged correspondingly to the limiting sleeve 10. During the stamping and forming process of the explosion-proof valve sheet, the upper mold 14 and the lower mold 9 will be closed. At this time, the limiting rods 15 will be aligned with the interior of the limiting sleeve 10 to guide the upper mold 14, so that the upper mold 14 and the lower mold 9 are closed more accurately, thereby improving the forming rate of the explosion-proof valve sheet. A spring 16 is installed on the outer side of the limiting rod 15, and the spring 16 is movably connected to the limiting rod 15. The spring 16 and the limiting rod 15 are used in conjunction with each other. When the upper mold 14 is pressed down, the lower side of the spring 16 conflicts with the limiting sleeve 10 and compresses the spring 16, which has a buffering effect on the upper mold 14, preventing the upper mold 14 and the lower mold 9 from being worn out under long-term use.

[0026] Working principle: when using the stamping die for the explosion-proof valve sheet, first turn on the external power supply, then place the lower die seat 6 above the base 1 and align the mounting hole 7 with the fixing hole 5, tighten the bolt 8 to fix the lower die seat 6, and then place the material strip above the lower die 9, and press the lower die 9 down through the upper die 14 to stamp and form it above the material strip. Secondly, the limiting rod 15 will be aligned and penetrate into the interior of the limiting sleeve 10, thereby guiding the upper die 14. When the upper die 14 is pressed down, the bottom of the spring 16 will contact the limiting sleeve 10 and compress the spring 16, which has a buffering effect on the upper die 14. Finally, after the stamping is completed, turn on the switch of the hydraulic cylinder 2, drive the hydraulic rod 3 to rise, and lift the ejecting block 4 upward, and eject the formed explosion-proof valve sheet, so as to carry out the next stamping. When the device is not used, cut off the external power supply of the device. The model of the hydraulic cylinder 2 is CDM2B25, and the use process of the stamping die for the explosion-proof valve sheet is completed.
