Description

Technical Field

[0001] The invention relates to the technical field of stamping equipment, in particular to an outer panel stamping forming device for computer production. Background Art

[0002] Stamping refers to a processing method in which a press and a die are used to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] A Chinese patent discloses a computer outer panel stamping and forming device in the field of stamping and forming device technology (Announcement No. CN111229903B), which includes a stamping and forming device shell, a conveyor belt, and a computer outer panel fixing component. An external condensing device continuously passes condensed water into the constant temperature plate. The condensed water flows along a spiral water channel. The spiral water channel increases the time the condensed water stays in the constant temperature plate, so that the constant temperature plate maintains a low temperature. The constant temperature plate transfers the low temperature to the cooling plate, which cools the conveyor belt locally. Whenever the conveyor belt transfers the computer outer panel to the lower side of the punching head, the local area is cooled, ensuring that the computer stamping plate is quickly cooled and formed after stamping. The second hydraulic cylinder shrinks Short, this patented technology can simultaneously extend the third hydraulic cylinder to move the pressing plate downward and press the L-shaped plate, so that the L-shaped plate has a fixing effect on the computer outer panel. This fixing method has a fixing effect on the lateral and vertical directions of the computer outer panel, which can effectively prevent the computer outer panel from sticking to the punching head. However, the secondary stamping device is only suitable for stamping outer panels with small curvature and depth. Panels with large curvature and depth are easily wrapped around the head of the punching head after stamping and cutting, and when fixed on the iron sheet transmitted by the conveyor belt during the stamping process, the fixed iron sheet is easily damaged under the punching and pulling. Therefore, the present invention provides a computer outer panel stamping forming device to solve the above-mentioned problems. Summary of the Invention

[0010] As a further solution of the present invention, a cutting knife is fixedly installed on the upper end of the stamping plate, and the cutting knife fits in with the cutting groove provided at the lower end of the cutting ring. When the cutting ring moves downward and fits in with the cutting knife, the iron sheet at the upper end of the stamping plate will be squeezed and cut by the cutting knife and the cutting ring, and a stripping ring is fixedly installed on the lower end of the stamping plate.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1.

When the formed iron sheet gradually increases, the discharge plate moves downward, and when the pushing rod provided at the lower end of the discharge plate is inserted into the limiting ring, the pushing rod squeezes and pushes the block to move downward, so that the block shrinks into the limiting rod, and pushes the spring rod to push the limiting ring to move, so that the fixed plate drives the discharge plate to move, and the stacked formed iron sheets are moved out of the collection box, so that the stamping device can process and discharge more conveniently.

[0016] 2. When the present invention is used, when the stamping mechanism is stamping the iron sheet, the stamping block moves downward to drive the linkage rod to move downward, so that the air pump starts to inflate the water tank. The air pressure in the water tank increases, so that the water in the water tank is transferred to the control box through the outlet pipe under the action of the air pressure. When the stamping block moves upward, it pushes the linkage frame to rotate, thereby rotating the control rod to open the control valve. Under the action of the atmospheric pressure of the water tank, the water in the control box is sprayed on the surface of the stamping block through the nozzle, thereby cooling the stamping block.

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments 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.

[0027] Example 1: Please refer to Figures 1 to 8A device for stamping and forming an outer panel for computer production includes a stamping machine 1. A stamping block 201 is fixedly installed at the output end of the stamping machine 1, and a protruding block for stamping materials is fixedly connected to the middle part of the lower end of the stamping block 201. A cooling mechanism 4 for cooling the stamping block 201 is provided on the left side of the stamping block 201 near the stamping block 201. The cooling mechanism 4 includes a water tank 401. The water in the water tank 401 is sprayed onto the surface of the stamping block 201 under the stamping force of the stamping block 201, thereby cooling the stamping block 201. The stamping machine 1 is fixedly installed at the upper end of the water tank 401. A plurality of spring extensions are rotatably installed at both the front and rear ends of the stamping block 201. A fixing ring 205 for flattening and fixing the material to be punched is symmetrically provided below the retracting rod 204 stamping block 201 (it is worth noting that the material referred to in this application is iron sheet), and the ends of the multiple spring telescopic rods 204 away from the stamping block 201 are rotatably connected to the fixing ring 205. A stamping plate 202 for shaping the iron sheet is also provided below the stamping block 201, and the stamping plate 202 is fixedly connected to the cooling mechanism 4. When the stamping block 201 moves downward, the fixing ring 205 will contact the material laid on the upper end of the stamping plate 202. As the stamping block 201 continues to move downward, the fixing ring 205 and the extrusion block compress the spring telescopic rod 205. 04, at this time the spring telescopic rod 204 will give the fixing ring 205 a reaction force, thereby making the two fixing rings 205 move in opposite directions, so that the iron sheet on the stamping plate 202 is tightened by the fixing ring 205, and a connecting rod 206 is slidably passed through the fixing rings 205, so that the fixing ring 205 can remain stable. A discharge mechanism is provided at the lower end of the stamping plate 202, and the discharge mechanism includes a collection box 301 and a discharge plate 304. The collection box 301 is fixedly connected to the lower end of the stamping plate 202, and the collection box 301 is fixedly connected to the water tank 401. The interior of the collection box 301 is slidably connected to the fixing plate 305. Specifically, the fixing plate 304 05 is fixedly connected to a plurality of mounting brackets 303 on the outer wall, and the number of the plurality of mounting brackets 303 is set to four. More specifically, the four mounting brackets 303 are distributed in a rectangular shape on the outer wall of the fixed plate 305, and the inner wall of the collection box 301 is symmetrically fixedly installed with a slide rail 302, and the mounting bracket 303 is slidingly connected to the collection box 301 through the slide rail 302, that is, the mounting bracket 303 is slidingly connected to the slide rail 302, and the upper end of the fixed plate 305 is also slidingly connected to the discharge plate 304. When the processed iron sheet is placed on the upper end of the discharge plate 304, the discharge plate 304 moves out of the collection box 301 along the slide rail 302, thereby making the device processing and discharging more convenient.

[0028] See also Figure 6 、 Figure 7The inner wall side end of the mounting frame 303 is fixedly installed with a pulling spring rod 306, and the output end of the pulling telescopic rod 306 is fixedly installed on the upper end of the discharge plate 304. When the punching block 201 punches the iron sheet, the punched iron sheet will fall to the upper end of the discharge plate 304. As the formed iron sheet increases, the discharge plate 304 will move downward. At this time, the pulling spring rod 306 will be stretched. When the iron sheet on the discharge plate 304 is removed, the pulling spring rod 306 pulls the discharge plate 304 to its original position. The lower end of the inner wall of the collection box 301 is fixedly installed with a pushing rod 306. The dynamic spring rod 307, the pushing spring rod 307 includes a fixed sleeve, a movable rod and a force storage spring. The force storage spring is located in the fixed sleeve, and the movable rod is slidably inserted in the fixed sleeve. The interior of the pushing spring rod 307 is also fixedly connected to a limiting rod 310. The movable rod is sleeved on the outer wall of the limiting rod 310, and the movable rod is slidably connected to the limiting rod 310. Specifically, the length of the limiting rod 310 is less than the length of the movable rod. A limiting ring 308 is fixedly installed on the end of the movable rod away from the fixed sleeve, and the limiting ring 308 is fixedly installed on the lower end of the fixed plate 305.

[0029] See also Figures 5 to 8 The interior of the limiting ring 308 is fixedly connected to a retaining groove cylinder 312, and a limiting window is provided on the outer wall of the retaining groove cylinder 312, and limiting windows are also provided on the outer walls of the limiting ring 308 and the fixed plate 305. The three limiting windows are on the same vertical line, and a groove is provided on the outer wall of the limiting rod 310, which is located inside the limiting ring 308. A stopper 311 adapted to the limiting window is slidably connected in the groove through a limiting spring 313. When the spring rod 307 is pushed to retract, the stopper 311 will be inserted into the limiting window, and a push rod 309 corresponding to the limiting window is fixedly installed on the lower end of the discharging plate 304 near the stopper 311;

[0030] Specifically, when the fixed plate 305 is pushed into the collection box 301, the limiting ring 308 will drive the movable rod to compress the storage spring. As the movable rod moves, the stop block 311 will move upward under the action of the limiting spring 313, thereby being inserted into the limiting window of the limiting ring 308, and then limiting the movable rod so that the storage spring is always in a compressed state.

[0031] See also Figure 5-Figure 6 The fixing ring 205 is movably connected to the cutting ring 203 inside, and a cutting groove is provided at the lower end of the cutting ring 203, and two telescopic plates 208 are symmetrically fixedly connected to the side wall of the cutting ring 203, and the telescopic plate 208 is fixedly connected to the fixing ring 205 at one end away from the cutting ring 203. The position of the cutting ring 203 can be limited by the telescopic plate 208, so that the cutting ring 203 is always in the middle of the fixing ring 205. Specifically, a connecting block 209 is fixedly installed on the inner wall of the fixing ring 205, and the cutting ring 203 is slidably connected to the connecting block 209.

[0032] See also Figure 6 The upper end of the stamping plate 202 is fixedly provided with a cutting knife 207, and the cutting knife 207 is matched with the cutting groove provided at the lower end of the cutting ring 203. When the cutting ring 203 moves downward and matches the cutting knife 207, the iron sheet at the upper end of the stamping plate 202 will be squeezed and cut by the cutting knife 207 and the cutting ring 203. The lower end of the stamping plate 202 is fixedly provided with a stripping ring 210, and a gap is provided in the middle of the stripping ring 210, and the gap in the middle is set to be trapezoidal, and the stripping ring 210 is set to rubber material. When the iron sheet is punched through the stamping plate 202 and the stripping ring 210, the cut iron sheet will be stuck on the outside of the raised block in the middle of the stamping block 201. At this time, when the stamping block 201 moves upward and resets, the iron sheet formed on the raised block is blocked by the stripping ring 210, so that the stamped iron sheet is scraped off by the stripping ring 210, so that the iron sheet falls onto the discharge plate 304.

[0033] The working principle of this embodiment is as follows: when it is necessary to process the iron sheet coil, the iron sheet conveyor is started to make the iron sheet start to move on the stamping plate 202. When the iron sheet moves to a suitable position, the iron sheet conveyor is closed and the stamping machine 1 is started to make the stamping block 201 move downward. When the stamping block 201 moves downward, the stamping block 201 drives the fixed ring 205 to move downward. When the fixed ring 205 contacts the iron sheet, the stamping block 201 continues to move downward, so that the fixed ring 205 and the extrusion block compress the spring telescopic rod 204, so that the fixed ring 205 moves to tighten the iron sheet placed on the stamping plate 202. The set stamping block 201 continues to move downward using the convex The starting block punches the iron sheet, and at this time the cutting ring 203 will cooperate with the cutting knife 207 to cut the iron sheet. When the cutting is completed, the fixing ring 205 and the cutting ring 203 no longer move downward after cutting, and the punching block 201 continues to move downward to punch the cut iron sheet. When the iron sheet is punched through the punching plate 202 and the stripping ring 210, the formed iron sheet will contact the discharge plate 304 and push the discharge plate 304 to move downward, and the punching block 201 ends its downward movement and resets upward. The iron sheet formed on the punching block 201 is blocked by the stripping ring 210, so that the processed iron sheet falls on the upper end of the discharge plate 304.

[0034] As the formed iron sheets gradually increase, the discharge plate 304 moves downward. When the push rod 309 set at the lower end of the discharge plate 304 is inserted into the limiting ring 308, the push rod 309 squeezes and pushes the stop block 311 to move downward, causing the stop block 311 to shrink into the limiting rod 310, pushing the spring rod 307 to push the limiting ring 308 to move, thereby causing the fixed plate 305 to drive the discharge plate 304 to move, and moving the stacked formed iron sheets out of the collection box 301, making the stamping device processing and discharging more convenient.

[0035] Example 2: Please refer to Figures 2 to 5The water tank 401 is rotatably installed with a sealing cover 402 at the upper end near the collecting box 301. The sealing cover 402 set in the water tank 401 makes it more convenient to add new coolant to the water tank 401. The side end of the stamping block 201 away from the spring telescopic rod 204 is fixedly installed with a linkage rod 403, and the end of the linkage rod 403 away from the stamping block 201 is fixedly installed with a piston rod 404, and the lower end of the piston rod 404 is fixedly installed with an air pump 405, and the air pump 405 is fixedly connected to the upper end of the water tank 401. The above-mentioned air pump 405 is a prior art and will not be described in detail again. The installed air pump 405 inflates the water in the process of the stamping rod moving up and down to stamp the iron plate, thereby causing the air pressure in the water tank 401 to begin to increase.

[0036] See also Figures 3-5 A water outlet pipe 408 is fixedly installed at the upper end of the water tank 401 near the air pump 405, and a control box 406 is fixedly installed at the upper end of the water outlet pipe 408, and the control box 406 is fixedly installed on the side end of the inner wall of the punching machine 1, and a water spray head 409 is fixedly installed at the side end of the control box 406 near the punching block 201, and water spray ports are provided at the upper and lower ends of the water spray head 409, so that the water spray head 409 can cool down the punching rod and the punching plate 202 at the same time when spraying water, and a control valve 407 is fixedly installed between the water spray head 409 and the control box 406, and the control valve 407 ensures that the water in the control box 406 that is pushed into the control box 406 by air pressure will not cool the punching block 201 when the punching machine 1 punches the iron sheet.

[0037] See also Figures 3-5 The punching machine 1 is fixed with a rotating rod 410 on the inner wall near the linkage rod 403. The outer wall of the rotating rod 410 is provided with a rotating cylinder 411, and a torsion spring is provided inside the rotating cylinder 411. A linkage frame 412 is provided on the upper end of the rotating cylinder 411 near the linkage rod 403. The linkage frame 412 is provided with an opening at one end near the linkage rod 403, and the opening of the linkage frame 412 is matched with the size of the linkage rod 403. When the linkage rod 403 is not in contact with the linkage frame 412, the opening of the linkage frame 412 is closed. Tilt downward, that is, when the linkage rod 403 follows the reset of the punch block 201, it will push the linkage frame 412 to rotate. The opening set in the linkage frame 412 enables the linkage rod 403 to push the rotating drum 411 to rotate when it moves up and down. A control rod 413 is rotatably connected between the rotating drum 411 and the control valve 407. When the linkage rod 403 drives the rotating drum 411 to rotate, the control rod 413 rotates, thereby opening the switch of the control valve 407, making it more convenient to control the water spraying of the sprinkler head 409.

[0038] The working principle of this embodiment is: when the punching machine 1 is punching the iron sheet, the punching block 201 moves downward, driving the linkage rod 403 to move downward, so that the air pump 405 starts to inflate the water tank 401, and the air pressure in the water tank 401 increases, so that the water in the water tank 401 is transferred to the control box 406 through the outlet pipe 408 under the action of the air pressure. When the punching block 201 moves upward, it pushes the linkage frame 412 to rotate, thereby rotating the control rod 413 to open the control valve 407. Under the action of the atmospheric pressure of the water tank 401, the water in the control box 406 is sprayed on the surface of the punching block 201 through the nozzle, thereby cooling the punching block 201.

[0039] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
