Abstract

The present invention discloses a stamping device for fitting processing, which includes a U-shaped chassis. At the top end of the inner wall of the U-shaped chassis, a recycling box is fixedly connected. At the top of the recycling box, a bottom frame is fixedly connected. At the top ends of the outer walls on both sides of the recycling box, L-shaped brackets are fixedly connected. A sliding ring is slidably connected to the outer wall of the second cylinder. A toughened glass plate penetrates through the center of the front end of the protective cover. The sliding ring can slide up and down on the outer wall of the second cylinder. Therefore, the protective cover can also move up and down independently. At this time, the second cylinder drives the stamping block to process the fitting, and the movement of the protective cover is not affected. At the same time, the second air pump installed on the protective cover is not affected either. By setting a sponge frame and a rubber frame, the sealing performance of the connection position between the protective cover and the bottom frame can be improved, thereby preventing heat leakage or debris from flying out. At the same time, it also has a good shock absorption effect, thus avoiding the shaking of the protective cover. By setting the toughened glass plate, it is convenient for the staff to observe the situation in the stamping area.

Description

Technical Field

[0001] The present invention relates to the technical field of hardware fitting processing, and particularly to a stamping device for fitting processing. Background Art

[0002] Hardware fittings are usually made of metal. Hardware fittings refer to machine parts or components made of hardware, as well as some small hardware products. They can be used alone or as assisting tools. Most small hardware products are not final consumer goods, but are used as supporting products, semi-finished products, and tools used in the production process in industrial manufacturing. Hardware fittings have a wide range of applications in various fields. In the industrial field, hardware fittings are widely used in the manufacturing and maintenance of mechanical equipment, instruments, electronic devices, etc. In the home field, hardware fittings are an indispensable part of furniture, doors and windows, kitchen and bathroom facilities, etc.

[0003] In the process of hardware fitting processing and production, for the processing of some fittings, stamping equipment is required. During the stamping process of some small metal fittings, the deformation generated by stamping will generate a certain amount of heat, and some debris may fly, and at the same time, it may also cause the metal fittings to bounce and affect the operation safety. Most of the existing stamping equipment does not have a protection structure. Based on these problems, Chinese Patent CN219541432U discloses a stamping device for hardware fitting processing. By placing the metal fitting to be stamped on the top of the lower die, then starting the hydraulic rod to extend, after the hydraulic rod extends, it drives the pressure plate to move, and makes the top frame and the bottom frame fit, and makes the upper die and the lower die press against each other. At this time, the first air pump is started, the first air pump inputs air flow into the annular pipe, the annular pipe outputs the air flow to the connecting pipe, the connecting pipe inputs the air flow into the inner sides of the top frame and the upper die, the air flow blows the positions inside the top frame and the bottom frame, and takes away the debris and heat. At the same time, the first air pump pumps air outwards, a negative pressure is formed inside the box body, and the air flow is extracted through the branch pipes and the ventilation holes. Cooperating with the blowing of the first air pump, the air flow heat and debris are intercepted by the filter frame. The overall structure is stable, facilitating heat dissipation and debris discharge, reducing the operation impact, and increasing the overall stability.

[0004] During the fitting processing, under normal circumstances, the hydraulic rod will drive the pressure plate to quickly move downward, forming a collision force and a squeezing force on the surface of the fitting, thereby effectively improving the stamping effect. In this device, if the hydraulic rod drives the pressure plate and the upper die to quickly move downward and collide with the lower die, it will cause the surface of the pressure plate to vibrate, which not only affects the stability of the first air pump structure, but also may cause the first air pump to fall off seriously. Since there is no structure for observing the stamping area in the top frame structure of this device, the staff cannot know the cleaning situation of the debris. Summary of the Invention

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] (1) The slip ring can slide up and down on the outer wall of the second cylinder. Therefore, the protective cover can also move up and down independently. At this time, the second cylinder drives the stamping block to process the fittings, and the movement of the protective cover is not affected. At the same time, the second air pump installed on the protective cover is not affected either. By setting the sponge frame and rubber frame, the sealing performance of the connection position between the protective cover and the bottom frame can be improved, thereby preventing heat leakage or debris from flying out. At the same time, it also has a good shock absorption effect, thus avoiding the shaking of the protective cover. By setting the tempered glass plate, it is convenient for the staff to observe the situation in the stamping area.

[0026] (2) By setting the first air pump and the air outlet pipe, the heat generated in the stamping device can be quickly discharged. By setting the second air pump and the air jet pipe structure, the air outlet of the air jet pipe is directly facing the stamping area. It can not only cool down the heat generated during the processing, but also quickly remove the generated debris. The main task of the sieve plate is to block the debris generated during the processing. These debris may be metal chips, plastic particles or small fragments of other materials. When debris is generated during the processing, they will be effectively blocked by the sieve plate, while the excess gas will smoothly pass through the gaps of the sieve plate and then be discharged from the air outlet pipe. When the blocked debris gradually accumulates on the top surface of the sieve plate, in order to prevent the situation that the sieve plate is blocked due to excessive debris accumulation, the first cylinder can drive the sieve plate to shake. At this time, the debris accumulated on it will quickly disperse, thus preventing the occurrence of blockage.

[0027] (3) By setting a simple connection method between the long-axis bolt, the first threaded pipe and the second threaded pipe, the disassembly and assembly steps of the stamping block are made more convenient and fast. By setting a simple connection method between the plug rod and the nut, and between the limit sleeve and the limit ring, the disassembly and assembly steps of the second air pump are made more convenient and fast. By setting the temperature detector, the temperature in the stamping area can be detected. By setting the temperature display, the detected temperature value can be displayed. Pinch the two groups of slide plates and move the two groups of slide plates in opposite directions at the same time. At this time, the plug block will disengage from the second square plug ring, and then the entire protective cover can be lifted upward. During the upward movement of the protective cover, the hand holding the slide plate can choose to hold the outer walls on both sides of the protective cover. When the protective cover moves to a certain height, the plug block will automatically insert into the first square plug ring, and at this time, the protective cover can be fixed again.
