Description

Technical Field

[0001] The present invention relates to the technical field of processing of well covers, and specifically to a device and method for processing and forming an aluminum alloy well cover. Background Art

[0002] A well cover usually refers to the lid of an inspection well, which is used to house and maintain various public facilities such as water pipes, cables, etc. The inspection well cover not only serves as a covering, but more importantly, it allows professionals to conduct regular inspections and maintenance. Therefore, the design and material of the well cover may need to consider more durability and pressure-bearing capacity to ensure the safe operation of the facilities.

[0003] Currently, in the manufacturing process of aluminum alloy well covers, it involves the coordinated operation of a stamping device and a transmission device. When performing stamping and forming, these two devices usually need to cooperate with each other to achieve intermittent conveying of the sheet material. However, currently, these two sets of equipment are often independently controlled by different control systems and lack a direct mechanical linkage mechanism.

[0004] In this design mode, if either the stamping device or the transmission device malfunctions and the other fails to respond and stop running in a timely manner, it is extremely easy to cause damage to the sheet material being processed, resulting in waste of the sheet material. Therefore, achieving mechanical linkage between the stamping device and the transmission device is of great significance for improving production efficiency and reducing product losses. Thus, it is necessary to develop a device and method for processing and forming an aluminum alloy well cover. Summary of the Invention

[0005] The purpose of this part is to outline some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. In this part, as well as in the abstract and title of the present application, some simplifications or omissions may be made to avoid obscuring the purpose of this part, the abstract, and the title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] To solve the above technical problems, according to one aspect of the present invention, the following technical solutions are provided:

[0007] An aluminum alloy well cover processing and forming device and method, which includes:

[0008] A base, the base includes a placement table and a base provided at the left end of the placement table, and side plates are respectively provided on the front, rear, left, and right sides of the base;

[0009] A stamping device, installed on the base for stamping and forming an aluminum alloy sheet, including a reciprocatingly lifting stamping plate;

[0010] The intermittent unidirectional conveying assembly is symmetrically installed on the front and rear sides of the placing table and is used for intermittently and unidirectionally conveying aluminum alloy plates. It includes a horizontal lead screw rotatably arranged on the side wall of the side plate, a horizontal slide bar fixed on the side wall of the side plate, and a mounting block screwed and driven on the lead screw rod body. On the upper and lower sides of each mounting block, there are symmetrically rotatably arranged clamping plates for reciprocally and intermittently clamping and conveying aluminum alloy plates. On the side close to each other of the two clamping plates on the same side in the front and rear, there is a horizontal card slot opened;

[0011] The adjusting assembly is spaced and installed on the left and right sides of the clamping plate. It includes an "L"-shaped follower plate sliding on the lead screw rod body. The follower plate is located on the left side of the clamping plate, and a clamping plate protrudes from the end of the follower plate close to the clamping plate. The thickness of the clamping plate is greater than the thickness of the aluminum alloy plate; on the left side walls of the two right-side side plates, there are fixedly protruding ejector plates aligned with the clamping plate;

[0012] The linkage assembly is installed on the stamping plate and the base. While the stamping plate moves up and down, the intermittent unidirectional conveying assembly is synchronously driven by the linkage assembly to intermittently and unidirectionally convey aluminum alloy plates. The length of the aluminum alloy plate conveyed by the intermittent unidirectional conveying assembly each time is not less than the length required for a sheet metal blank.

[0013] As a preferred scheme of an aluminum alloy well box cover processing and forming device according to the present invention, among them: on the upper surface of the placing table, there is an inlaid row of rotating rollers installed at equal intervals. The surface of the rotating roller protrudes from the upper edge of the placing table and is sleeved with a buffer sleeve.

[0014] As a preferred scheme of an aluminum alloy well box cover processing and forming device according to the present invention, among them: the stamping device further includes vertical guide columns arranged around the top of the base. At the top of the four guide columns, there is a top seat together. At the top of the top seat, there is a vertical electric cylinder. The output end of the electric cylinder slides through the top of the top seat through a first linear bearing and is connected to the center of the top of the stamping plate. At the bottom of the stamping plate, there is an upper mold. On the top of the base, directly below the upper mold, there is a lower mold adapted to the upper mold. After the upper mold and the lower mold are closed, there is a chamber for stamping and forming the aluminum alloy plate. The upper mold further includes a punch for punching off the aluminum alloy plate.

[0015] As a preferred scheme of an aluminum alloy well box cover processing and forming device according to the present invention, among them: when the clamping plate is used to insert into the slots of the two card slots on the same side in the front and rear, the distance between the two clamping plates on the same side in the front and rear is enlarged, so that the clamping plates cannot clamp and convey the aluminum alloy plate;

[0016] The width of the upper and lower sides of the ejector plate is always smaller than the distance between the two card slots on the same side. The ejector plate is used to eject the card inserted into the card slot, thereby reducing the distance between the two clamping plates on the same side, so that the clamping plates can clamp and convey the aluminum alloy plates.

[0017] As a preferred solution of the aluminum alloy manhole box cover processing and forming device described in the present invention, the clamping plate includes a clamping piece arranged close to one side of the aluminum alloy plate, and the other side of the clamping plate is hingedly provided with a spring, and the other end of the spring is hinged on the mounting block.

[0018] As a preferred solution of the aluminum alloy manhole box cover processing and forming device described in the present invention, the side wall of the mounting block is provided with a first sliding hole for the sliding rod body to slide through, and a screw hole for the screw rod body to thread through.

[0019] As a preferred solution of the aluminum alloy manhole box cover processing and forming device described in the present invention, when the two clamps clamp the aluminum alloy plate, the distance between the two clamping grooves on the same side of the front and rear is less than the thickness of the clamping plate.

[0020] As a preferred solution of the aluminum alloy manhole box cover processing and forming device described in the present invention, the linkage assembly includes a vertical rack arranged on the front and rear side walls of the stamping plate, a fixing frame is arranged on the front and rear side walls of the base, a horizontal rotating rod is rotatably arranged on the side wall of the fixing frame, and a follower gear meshing with the rack is arranged on the rod body of the rotating rod, the two follower gears rotate in the same direction, and the right ends of the two rotating rods drive the screw rod to rotate after the speed is changed by the speed change assembly.

[0021] As a preferred solution of the aluminum alloy manhole box cover processing and forming device described in the present invention, the speed change assembly includes a horizontal linkage rod on a rotating fixed frame, and a speed change gear 1 and a speed change gear 2 are arranged on the rod body of the linkage rod, and a speed change gear 3 meshing with the speed change gear 1 is arranged on the rod body of the rotating rod, and the diameter of the speed change gear 3 is larger than the diameter of the speed change gear 1. The left end of the screw rod extends and rotates through the side wall of the left side plate and is provided with a speed change gear 4 meshing with the speed change gear 2, and the diameter of the speed change gear 2 is larger than the diameter of the speed change gear 4.

[0022] As a preferred solution of the aluminum alloy manhole cover processing and forming method described in the present invention, it includes the following steps:

[0023] Step 1: The stamping plate is at the highest point when initialized, and the two clamps are held open by the clamping plate. The aluminum alloy plate to be processed is placed on the top of the lower die, and the electric cylinder is started to control the stamping plate to drive the upper die and punch to descend;

[0024] Step 2: When the stamping plate descends, the rack drives the follower gear and the rotating rod to rotate, and then the speed change assembly drives the lead screw to rotate clockwise;

[0025] Step 1: When the screw rod rotates clockwise, it drives the mounting block to move from left to right. Since the two clamping plates are held apart by the card plate, the aluminum alloy plate cannot be moved. When the mounting block moves to the side plate close to the right side, the left end of the ejector plate touches the right end of the card plate. When the mounting block continues to move to the right, the ejector plate ejects the card plate out of the card slot, thereby reducing the distance between the two clamping plates on the same side, so that the two clamping plates clamp the aluminum alloy plate.

[0026] Step 3: When the two clamps clamp the aluminum alloy sheet, the upper mold and the lower mold are completely closed to punch the aluminum alloy sheet into the required sheet metal blank;

[0027] Step 4: The electric cylinder controls the stamping plate to rise, the rack drives the follower gear to rotate and the rotating rod to rotate counterclockwise, and then drives the lead screw to rotate counterclockwise through the speed change assembly;

[0028] Step 5. When the screw rotates counterclockwise, it drives the mounting block to move from right to left. Since the two clamps clamp the aluminum alloy sheet at this time, the aluminum alloy sheet can be clamped and conveyed. In the process of movement of the two clamps, they will touch and push the follower plate to slide from right to left along the rod body of the slide rod until the left side of the follower plate hits the right side wall of the left side plate and cannot move. At this time, the clamp continues to move to the left, and the clamping plate will be inserted into the two clamping grooves on the same side of the front and back again. The distance between the two clamps is enlarged, and the clamping of the aluminum alloy sheet is released. Therefore, when the screw rotates repeatedly, the clamping plate can reciprocate and intermittently clamp and convey the aluminum alloy sheet, thereby gradually stamping the aluminum alloy sheet into the required sheet metal blanks.

[0029] The beneficial effects of the present invention are as follows: driven by the electric cylinder, the stamping plate realizes reciprocating lifting and lowering motion, and at the same time, through the coordinated action of the linkage assembly and the intermittent one-way conveying assembly, the clamping plate can complete the reciprocating intermittent clamping and conveying process of the aluminum alloy plate. The aluminum alloy plate is gradually conveyed to the required position to form a qualified sheet metal blank. This linkage mechanism ensures that the aluminum alloy plate is conveyed only when the stamping plate is in an active state, effectively avoiding the problem of plate damage or resource waste caused by the failure of a single mechanism causing another mechanism to continue to operate.

Detailed implementation manners

[0042] In order to make the above objects, features and advantages of the present invention more obvious and understandable, the following detailed description of the specific implementation manners of the present invention will be given with reference to the accompanying drawings.

[0043] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0044] Secondly, the present invention will be described in detail with reference to the schematic diagrams. When detailing the implementation manners of the present invention, for the convenience of description, the cross-sectional views showing the device structure will be enlarged locally not in accordance with the general ratio, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width and depth should be included.

[0045] In order to make the purpose, technical solution and advantages of the present invention clearer, the following will further describe the implementation manners of the present invention in detail with reference to the accompanying drawings.

[0046] Please refer to Figures 1 - 10 , which shows a schematic structural diagram of an implementation manner of an aluminum alloy well box cover processing and forming device and method of the present invention. Please refer to Figures 1 - 10 , and a detailed introduction will be given to an aluminum alloy well box cover processing and forming device and method.

[0047] An aluminum alloy well box cover processing and forming device and method, including a base 100, a stamping device 200, an intermittent one-way conveying assembly 300, an adjusting assembly 400 and a linkage assembly 500

[0048] The base 100 includes a placement table 101 and a base 102 disposed at the left end of the placement table 101. Side plates 103 are respectively arranged on the front, rear, left, and right sides of the base 102. A row of rotating rollers 104 are embedded and equidistantly installed on the upper surface of the placement table 101. The surface of the rotating roller 104 protrudes from the upper edge of the placement table 101 and is sleeved with a buffer sleeve. When the aluminum alloy plate 600 is conveyed, the friction generated between the aluminum alloy plate 600 and the upper edge of the placement table 101 during conveyance is reduced by the provided rotating rollers 104.

[0049] The stamping device 200 is installed on the base 102 for stamping and forming the aluminum alloy plate 600, and includes a reciprocating stamping plate 201. The stamping device 200 further includes vertical guide columns 202 arranged around the top of the base 102. A top seat 203 is commonly provided at the tops of the four guide columns 202. A vertical electric cylinder 204 is provided at the top of the top seat 203. The output end of the electric cylinder 204 slidably penetrates through the top of the top seat 203 through a first linear bearing and is connected to the center of the top of the stamping plate 201. A top die is provided at the bottom of the stamping plate 201. A bottom die adapted to the top die is provided directly below the top die at the top of the base 102. A chamber for stamping and forming the aluminum alloy plate 600 is formed after the top die and the bottom die are closed. The top die further includes a punch for punching off the aluminum alloy plate 600.

[0050] The stamping plate 201 is respectively slidably penetrated by the four guide columns 202 near its four top corners, and a second linear bearing is provided at the penetrated position of the stamping plate 201. The second linear bearing is sleeved on the outer side wall of the rod body of the guide column 202. When the electric cylinder 204 drives the stamping plate 201 to lift and lower, the stamping plate 201 lifts and lowers along the guide column 202. The guide column 202 plays a role in limiting and guiding the stamping plate 201, and the provided second linear bearing also reduces the friction generated during their relative movement.

[0051] The aluminum alloy plate 600 is conveyed between the top die and the bottom die. When the electric cylinder 204 drives the stamping plate 201 to descend and then ascend, it drives the top die and the punch to combine with the bottom die and then release, stamping the aluminum alloy plate 600 into the required sheet metal blank 601.

[0052] The intermittent unidirectional conveying assembly 300 is symmetrically installed on the front and rear sides of the placing table 101 and is used for intermittently and unidirectionally conveying the aluminum alloy plate 600. It includes a horizontal lead screw 301 rotatably arranged on the side wall of the side plate 103, a horizontal slide bar 302 fixed on the side wall of the side plate 103, and a mounting block 303 screwed and driven on the rod body of the lead screw 301. The thread directions of the two lead screws 301 are the same. A clamping plate 304 for reciprocally and intermittently clamping and conveying the aluminum alloy plate 600 is symmetrically and rotatably arranged above and below each mounting block 303. A horizontal clamping groove 305 is formed on the side of the two clamping plates 304 on the same side of the front and rear that are close to each other; the width of the aluminum alloy plate 600 is greater than the width of the placing table 101, so that the outer edge of the aluminum alloy plate 600 protrudes, which is convenient for the slide bar 302 to clamp and convey.

[0053] The clamping plate 304 includes a clamping piece 306 arranged on the side close to the aluminum alloy plate 600. A spring 307 is hinged on the other side of the clamping plate 304, and the other end of the spring 307 is hinged on the mounting block 303; when the two clamping plates 304 on the same side of the front and rear are only under the pushing force of the spring 307, the two clamping pieces 306 at the other ends of the two clamping plates 304 clamp the outer sides of the upper and lower surfaces of the aluminum alloy plate 600. If the mounting block 303 moves at this time, the aluminum alloy plate 600 will be driven to be conveyed; an anti-slip pad 308 is arranged on the side of the clamping piece 306 facing the aluminum alloy plate 600. When the clamping piece 306 clamps the aluminum alloy plate 600, the set anti-slip pad 308 increases the contact friction force.

[0054] A first sliding hole 309 for the rod body of the slide bar 302 to slide through is opened on the side wall of the mounting block 303. A third linear bearing is arranged inside the first sliding hole 309, and the third linear bearing is sleeved on the outer side of the rod body of the slide bar 302, and a threaded hole 310 for the rod body of the lead screw 301 to be screwed and driven through; when the lead screw 301 rotates, since the mounting block 303 is restricted by the slide bar 302 and cannot rotate, it will move along the rod body directions of the lead screw 301 and the slide bar 302. At least two slide bars 302 are arranged on one side of the front and rear, so as to ensure that the mounting block 303 cannot rotate around the slide bar 302 and can only move horizontally along the two slide bars 302;

[0055] The adjusting assembly 400 is installed at intervals on the left and right sides of the clamping plate 304. It includes an "L"-shaped follower plate 401 sliding on the rod body of the slide bar 302. The follower plate 401 is located on the left side of the clamping plate 304, and a clamping plate 402 protrudes from the end of the follower plate 401 close to the clamping plate 304. The thickness of the clamping plate 402 is greater than the thickness of the aluminum alloy plate 600;

[0056] When the clamping plate 402 is inserted into the two clamping slots 305 on the same side of the front and rear, the distance between the two clamping plates 304 on the same side of the front and rear is enlarged, so that the clamping plates 304 cannot clamp and convey the aluminum alloy plate 600; when the mounting block 303 moves from right to left, the clamping plates 304 clamp and convey the aluminum alloy plate 600, and when the mounting block 303 moves to the side plate 103 close to the left, the two clamping plates 304 will touch the clamping plate 402, and when the mounting block 303 continues to move to the left, the clamping plate 402 will be inserted into the clamping slot 305, thereby enlarging the distance between the two clamping plates 304 on the same side of the front and rear, so that the clamping plates 304 cannot clamp and convey the aluminum alloy plate 600, and at this time, the spring 307 is further compressed, and the outer edge of the clamping slot 305 and the outer edge of the clamping plate 402 are both chamfered smoothly, so that when the two are in contact, the clamping plate 402 is better inserted into the clamping slot 305;

[0057] Among them, the left side walls of the two right side plates 103 are fixedly protruded with ejector plates 403 aligned with the card plates 402, and the width of the upper and lower sides of the ejector plates 403 is always smaller than the spacing between the two card slots 305 on the same side at the front and back. The ejector plates 403 are used to eject the card plates 402 inserted into the inner sides of the card slots 305, thereby reducing the spacing between the two clamping plates 304 on the same side at the front and back, so that the clamping plates 304 can clamp and convey the aluminum alloy plate 600; when the mounting block 303 moves from left to right, since the spring 307 still applies a thrust to the end of the clamping plate 304 at this time, the two clamping plates 304 will generate a clamping force on the card plates 402, so when the clamping plate 304 moves from left to right, it will also drive the follower plate 401 and the card plate 402 to slide from left to right along the rod body of the slide rod 302, and the side wall of the follower plate 401 is provided with a second sliding hole 404, and the second sliding hole A fourth linear bearing is installed on the inner side of the hole 404, and the inner side of the fourth linear bearing slides on the outer side of the rod body of the slide bar 302. The fourth linear bearing is set to reduce the friction between the follower plate 401 and the clamping plate 402 when they slide, which is beneficial for the clamping plate 304 to drive them to move. Since the two clamping plates 304 are spread apart by the clamping plate 402, when the mounting block 303 moves from left to right, it cannot drive the aluminum alloy plate 600 to move, and will not hinder the stamping of the aluminum alloy plate 600. When the mounting block 303 moves to the side plate 103 close to the right side, the left end of the ejector plate 403 will touch the right end of the clamping plate 402. When the mounting block 303 continues to move to the right, the ejector plate 403 will eject the clamping plate 402 out of the clamping slot 305, thereby reducing the distance between the two clamping plates 304 on the same side, so that the clamping plate 304 can clamp and convey the aluminum alloy plate 600.

[0058] When the two clamping pieces 306 clamp the aluminum alloy plate 600, the distance between the two clamping grooves 305 on the same side, front and back, is less than the thickness of the clamping plate 402; when the ejector plate 403 ejects the clamping plate 402 out of the inner side of the clamping groove 305, and then the mounting block 303 moves from right to left, due to the relatively small friction force of the follower plate 401, and the thickness of the clamping plate 402 is greater than the current distance between the two clamping grooves 305, the two clamping plates 304 will touch and push the follower plate 401 to slide from right to left along the rod body of the sliding rod 302. Until the left side of the follower plate 401 abuts against the right side wall of the left side plate 103 and cannot move, the clamping plate 402 will be inserted into the two clamping grooves 305 on the same side, front and back again, and the distance between the two clamping plates 304 will expand, releasing the clamping of the aluminum alloy plate 600. Therefore, when the lead screw 301 rotates repeatedly, the clamping plate 304 reciprocates intermittently to clamp and convey the aluminum alloy plate 600;

[0059] The linkage assembly 500 is installed on the stamping plate 201 and the base 102. While the stamping plate 201 moves up and down, the intermittent one-way conveying assembly 300 is synchronously driven by the linkage assembly 500 to intermittently convey the aluminum alloy plate 600 in one direction; the linkage assembly 500 includes vertical racks 501 arranged on the front and rear side walls of the stamping plate 201. Fixed frames 502 are arranged on the front and rear side walls of the base 102. A horizontal rotating rod 503 is rotatably arranged on the side wall of the fixed frame 502. A follower gear 504 meshing with the rack 501 is arranged on the rod body of the rotating rod 503. The two follower gears 504 rotate in the same direction. The right ends of the two rotating rods 503 are driven by a speed change assembly 505 to drive the lead screw 301 to rotate;

[0060] The speed change assembly 505 includes a horizontal linkage rod 506 rotatably fixed on the fixed frame 502. A first speed change gear 507 and a second speed change gear 508 are arranged on the rod body of the linkage rod 506. A third speed change gear 509 meshing with the first speed change gear 507 is arranged on the rod body of the rotating rod 503. The diameter of the third speed change gear 509 is larger than that of the first speed change gear 507. The left end of the lead screw 301 extends through the side wall of the left side plate 103 and is rotatably provided with a fourth speed change gear 510 meshing with the second speed change gear 508. The diameter of the second speed change gear 508 is larger than that of the fourth speed change gear 510. Since the number of turns of the follower gear 504 driven by the rack 501 is limited when the rack 501 moves up and down, the speed change assembly 505 enables the lead screw 301 to rotate enough turns for the clamping plate 304 to clamp and move the aluminum alloy plate 600. It should be noted that after being speed-changed by the speed change assembly 505, when the stamping plate 201 moves up and down once, the clamping plate 304 moves back and forth left and right exactly once, and the length conveyed by the clamping plate 304 is not less than the length required for a sheet metal blank 601. A method for processing and forming an aluminum alloy well cover includes the following steps:

[0061] Step 1: The stamping plate 201 is at the highest point when initialized, and the two clamping plates 304 are held open by the clamping plate 402. The aluminum alloy plate to be processed is placed on the top of the lower die, and the electric cylinder 204 is started to control the stamping plate 201 to drive the upper die and the punch to descend;

[0062] Step 2: When the stamping plate 201 descends, the rack 501 drives the follower gear 504 and the rotating rod 503 to rotate, and then the speed change assembly 505 drives the screw rod 301 to rotate clockwise;

[0063] Step 3, when the screw rod 301 rotates clockwise, it drives the mounting block 303 to move from left to right. Since the two clamping plates 304 are held apart by the clamping plate 402, they cannot drive the aluminum alloy plate 600 to move. When the mounting block 303 moves close to the side plate 103 on the right side, the left end of the ejection plate 403 touches the right end of the clamping plate 402. When the mounting block 303 continues to move to the right, the ejection plate 403 ejects the clamping plate 402 out of the clamping slot 305, thereby reducing the distance between the two clamping plates 304 on the same side, so that the two clamping plates 304 clamp the aluminum alloy plate 600.

[0064] Step 4: When the two clamping plates 304 clamp the aluminum alloy plate 600, the upper mold and the lower mold are completely closed to punch the aluminum alloy plate 600 into the required sheet metal blank 601;

[0065] Step 5, the electric cylinder 204 controls the stamping plate 201 to rise, the rack 501 drives the follower gear 504 to rotate and the rotating rod 503 to rotate counterclockwise, and then drives the screw rod 301 to rotate counterclockwise through the speed change assembly 505;

[0066] Step 6, when the screw rod 301 rotates counterclockwise, it drives the mounting block 303 to move from right to left. Since the two clamping plates 304 clamp the aluminum alloy sheet 600 at this time, the aluminum alloy sheet 600 can be clamped and conveyed. During the movement of the two clamping plates 304, they will touch and push the follower plate 401 to slide from right to left along the rod body of the slide rod 302 until the left side of the follower plate 401 hits the right side wall of the left side plate 103 and cannot move. At this time, the clamping plate 304 continues to move to the left, and the clamping plate 402 will be inserted into the two clamping grooves 305 on the same side of the front and back again. The distance between the two clamping plates 304 is enlarged, and the clamping of the aluminum alloy sheet 600 is released. Therefore, when the screw rod 301 rotates repeatedly, the clamping plates 304 can reciprocate and intermittently clamp and convey the aluminum alloy sheet 600, thereby gradually stamping the distance between the aluminum alloy sheet 600 into the required sheet metal blank 601.

10. A method for processing and forming an aluminum alloy manhole cover, which is realized by the aluminum alloy manhole cover processing and forming device according to claims 1-8, characterized in that: The following steps are involved: Step 1: The stamping plate (201) is initially located at the highest point, and the two clamping plates (304) are held open by the clamping plate (402). The aluminum alloy plate to be processed is placed on the top of the lower mold, and the electric cylinder (204) is started to control the stamping plate (201) to drive the upper mold and the punch to descend; Step 2: When the stamping plate (201) descends, the rack (501) drives the follower gear (504) and the rotating rod (503) to rotate, and then the speed change assembly (505) drives the screw rod (301) to rotate clockwise; Step 3, when the screw rod (301) rotates clockwise, it drives the mounting block (303) to move from left to right. Since the two clamping plates (304) are held apart by the clamping plate (402), the aluminum alloy plate (600) cannot be driven to move. When the mounting block (303) moves close to the side plate (103) on the right side, the left end of the ejection plate (403) touches the right end of the clamping plate (402). When the mounting block (303) continues to move to the right, the ejection plate (403) ejects the clamping plate (402) out of the clamping slot (305), thereby reducing the distance between the two clamping plates (304) on the same side, so that the two clamping plates (304) clamp the aluminum alloy plate (600). Step 4: When the two clamping plates (304) clamp the aluminum alloy plate (600), the upper mold and the lower mold are completely closed to punch the aluminum alloy plate (600) into the required sheet metal blank (601); Step 5, the electric cylinder (204) controls the stamping plate (201) to rise, the rack (501) drives the follower gear (504) to rotate and the rotating rod (503) to rotate counterclockwise, and then drives the screw rod (301) to rotate counterclockwise through the speed change assembly (505); Step 6: When the screw rod (301) rotates counterclockwise, it drives the mounting block (303) to move from right to left. Since the two clamping plates (304) clamp the aluminum alloy plate (600), the aluminum alloy plate (600) can be clamped and conveyed. During the movement of the two clamping plates (304), they will touch and push the follower plate (401) to slide from right to left along the rod body of the slide rod (302) until the left side of the follower plate (401) hits the right side of the left side plate (103). After the side wall cannot move, the clamping plate (304) continues to move to the left, and the clamping plate (402) is inserted into the two clamping grooves (305) on the same side at the front and back again, and the distance between the two clamping plates (304) is enlarged, loosening the clamping of the aluminum alloy plate (600). Therefore, when the screw rod (301) rotates repeatedly, the clamping plate (304) reciprocates and intermittently clamps and conveys the aluminum alloy plate (600), thereby gradually stamping the distance between the aluminum alloy plate (600) into the required sheet metal blank (601).
