[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. Spraying lubricant can reduce the surface wear of metal lampshade. The control system connects the heating wire to the circuit, and heats the heat-conducting medium through the heating wire. The heat-conducting medium expands and squeezes the expansion film after absorbing the heat.

[0024] 2. Heat treatment at the stamping position to reduce stress during the forming process. When the negative plate and the positive plate are in contact with the upper and lower sides of the plate respectively, the pressure pump feeds back the pressure data of the pressurized air to the control system. The control system connects the negative plate and the positive plate to the negative and positive poles of the power supply respectively. The current flows through the plate between the positive plate and the negative plate, causing the plate to heat up at the position where it needs to be stamped, reducing the stress during the stamping process.

[0025] 3. Cooling treatment of the upper die seat to extend the service life of the upper die seat. The control system cools the flexible film through the refrigeration end, and the flexible film cools the air in the spiral tube. The low-temperature air is transported to the air outlet through the pipeline, and the low-temperature air is sprayed on the upper die seat through the air outlet. The low-temperature air cools the upper die seat and cleans it at the same time. After the impurities on the upper die seat are blown off, the collection cover absorbs the impurities and deposits them on the filter net. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] A pole 431 is provided on the outside of each turn of the coil spring 43, and a spiral tube 46 is installed on the outside of the coil spring 43. The inner side of each turn of the spiral tube 46 is connected to each turn of the coil spring 43 through the pole 431, and each turn of the spiral tube 46 is connected to the blowing port 401 through a pipeline through the partition 402; one end of the spiral tube 46 passes through the blowing hood 4 through the pipeline and is connected to the outlet of the vacuum pump (not shown in the figure), and the inlet of the vacuum pump is connected to the collecting hood 41 through the pipeline. A filter screen (not shown in the figure) is provided in the middle of the collecting hood 41, and the vacuum pump is installed on the frame 11.

[0043] A stamping cover 115 is installed on the outer side of the lower die base 32, and the stamping cover 115 is arranged on the frame 11, and a third spring is connected between the lower die base 32 and the frame 11; the upper die base 31 is hollow inside, and a plurality of electromagnets (not shown in the figure) are arranged on the outer side of the upper die base 31, and another set of vacuum pumps is connected to the upper side of the upper die base 31 through a pipeline, and electromagnetic valves and flow meters are installed in the pipelines connected by the spiral tube 46, the pipelines connected by the collecting cover 41, the pipelines connected by the detecting cylinder 2, and the pipelines connected by the upper die base 31, and the electromagnetic valves and flow meters are electrically connected to the control system.

[0044] Working principle: Press the start button on the control panel 1, the forming device starts, and the plate 13 is conveyed through a plurality of conveying wheels 12. The conveying wheels 12 drive the plate 13 to move to the right, so that the position of the plate 13 that needs to be stamped is located directly below the detection cylinder 2.

[0045] When the position of the plate 13 that needs to be punched is located directly below the detection cylinder 2, the plate 13 presses the positive plate 24 down by its own weight, and the positive plate 24 slides downward on the guide shaft and compresses the second spring, and the positive plate 24 contacts the lower side of the plate 13. The encoder inside the conveying wheel 12 feeds back the displacement data of the plate 13 to the control system, and the control system opens the solenoid valve in the pipeline between the detection cylinder 2 and the pressure pump. The pressure pump pressurizes the external air and conveys it to the upper side of the detection cylinder 2 through the pipeline. The pressurized air pushes the sliding plate 21 to move downward while stretching the first spring. The sliding plate 21 drives the cover plate 223 to move downward through the sliding shaft, and the air between the lower side of the sliding plate 21 and the detection cylinder 2 is discharged through the exhaust port. The cover plate 223 drives the annular plate 22 and the negative plate 23 to move downward, so that the negative plate 23 contacts the upper side of the plate 13.

[0046] When the negative plate 23 and the positive plate 24 are in contact with the upper and lower sides of the plate 13 respectively, the pressure pump feeds back the pressure data of the pressurized air to the control system, and the control system connects the negative plate 23 and the positive plate 24 to the negative pole and the positive pole of the power supply respectively. The current flows through the plate 13 between the positive plate 24 and the negative plate 23 (the current flows through the position that needs to be stamped), causing the position of the plate 13 that needs to be stamped to heat up, thereby reducing the stress during the stamping process.

[0047] When the stamping position of the plate 13 is heated, the control system connects the heating wire to the circuit to heat the heat-conducting medium through the heating wire. The heat-conducting medium absorbs the heat and expands and squeezes the expansion membrane 221. The expansion membrane 221 squeezes the lubricating liquid and sprays it from the spray port 222 to the stamping position of the plate 13. Although the lubricating liquid will lower the temperature of the stamping position, the temperature of the stamping position is still relatively high. The lubricating liquid can reduce the wear of the upper die base 31 and the metal lampshade during the stamping process, thereby extending the service life of the upper die base 31.

[0048] After the lubricating liquid is sprayed on the position of the plate 13 that needs to be stamped, the conveying wheel 12 continues to drive the plate 13 to move to the right, and moves the position of the plate 13 that needs to be stamped (the position after the lubricating liquid is sprayed) to be directly below the upper die seat 31. The hydraulic cylinder 3 drives the upper die seat 31 to move downward, and the upper die seat 31 and the stamping cover 115 cooperate to punch the plate 13 into a disc. The upper die seat 31 drives the disc to move downward and stamp it on the lower die seat 32. The metal lampshade is stamped by the cooperation of the upper die seat 31 and the lower die seat 32, so that the disc is formed into a metal lampshade.

[0049] After the sheet 13 is punched into a metal lampshade, the hydraulic cylinder 3 feeds back the displacement data of the upper die seat 31 to the control system, and the control system opens the solenoid valve in the pipeline between the upper die seat 31 and the vacuum pump, and the metal lampshade is adsorbed by the vacuum pump (the vacuum pump connected to the upper die seat 31 by a pipeline) and the upper die seat 31. Several electromagnets on the upper die seat 31 are energized at the same time to attract the metal lampshade to increase the adsorption force of the metal lampshade, so that the metal lampshade is stably adsorbed on the upper die seat 31, and the hydraulic cylinder 3 drives the adsorbed metal lampshade to move upward through the upper die seat 31; then, the telescopic cylinder 34 drives the limit plate 33 to move right, the limit plate 33 drives the hydraulic cylinder 3 and the upper die seat 31 to move right, and the upper die seat 31 drives the metal lampshade to move right, so that the metal lampshade is located above the adsorption belt 15, and the hydraulic cylinder 3 drives the metal lampshade to move downward through the upper die seat 31 and is located on the adsorption belt 15.

[0050] When the metal lampshade is located on the adsorption belt 15, the hydraulic cylinder 3 feeds back the displacement data of the metal lampshade to the control system, the control system cuts off the power to several electromagnets, and cooperates with the vacuum pump and the upper die seat 31 to stop adsorbing the metal lampshade. At this time, the metal lampshade is not adsorbed and is located on the adsorption belt 15. The hydraulic cylinder 3 drives the upper die seat 31 to move upward, and the roller 14 drives the metal lampshade to move to the right. The staff removes the formed metal lampshade for further processing.

[0051] After the hydraulic cylinder 3 drives the upper mold base 31 to move upward, the telescopic cylinder 34 drives the hydraulic cylinder 3 and the upper mold base 31 to move to the left through the limit plate 33, so that the upper mold base 31 moves to the position between the blowing hood 4 and the collecting hood 41, and the control system opens the solenoid valves in the connecting pipes of the collecting hood 41 and the blowing hood 4, and the vacuum pump (the vacuum pump connected to the collecting hood 41) works, and the external air is sucked into the collecting hood 41, and enters the vacuum pump (the vacuum pump connected to the collecting hood 41) after being filtered through the filter, and then is pressurized by the vacuum pump and transported to the spiral tube 46 of the blowing hood 4.

[0052] When the pressurized air enters the spiral tube 46, the flow meter in the connecting pipe of the spiral tube 46 feeds back the data to the control system, and the control system controls the two semiconductors on the refrigeration plate 45 to access the circuit. The two semiconductors and the metal plate on the refrigeration plate 45 are the refrigeration end of the Peltier effect. The control system cools the flexible membrane 44 through the refrigeration end, and the flexible membrane 44 cools the air in the spiral tube 46. The low-temperature air is transported to the blowing port 401 through the pipeline, and the low-temperature air is sprayed onto the upper mold base 31 through the blowing port 401. The low-temperature air cools the upper mold base 31 and cleans it at the same time. After the impurities on the upper mold base 31 are blown off, the collecting hood 41 adsorbs the impurities and deposits them on the filter net.

Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
