[0002] The box cover generally refers to the cover of the inspection well, which is used to accommodate and maintain various public facilities such as water pipes, cables, etc. The inspection well cover not only plays a covering role, but more importantly, it allows professionals to conduct regular inspection and maintenance. Therefore, the design and material of the well box 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 box covers, the stamping device and the conveying device cooperate with each other.

[0049] The stamping device 200 is installed on the base 102 for stamping and forming the aluminum alloy plate 600, and comprises a reciprocating lifting stamping plate 201; the stamping device 200 further comprises vertical guide columns 202 arranged around the top of the base 102, and the top of the four guide columns 202 is commonly provided with a top base 203, the top of the top base 203 is provided with a vertical electric cylinder 204, the output end of the electric cylinder 204 penetrates the top of the top base 203 through a first linear bearing and is connected to the top center of the stamping plate 201, the bottom of the stamping plate 201 is provided with an upper die, the top of the base 102 located directly below the upper die is provided with a lower die matched with the upper die, the upper die and the lower die form a cavity for stamping and forming the aluminum alloy plate 600 after being closed, and the upper die further comprises a punch for punching the aluminum alloy plate 600;

[0050] The stamping plate 201 is slidably penetrated by the four guide columns 202 near the four top corners thereof, and the stamping plate 201 is provided with a second linear bearing at the penetrated position, the second linear bearing is sleeved on the outer wall of the rod of the guide column 202, when the electric cylinder 204 drives the stamping plate 201 to lift, the stamping plate 201 lifts along the guide column 202, and the guide column 202 plays a limiting and guiding role on the stamping plate 201, and the second linear bearing arranged also reduces the frictional force generated by the relative movement of the two;

[0051] The aluminum alloy plate 600 is conveyed between the upper die and the lower die, when the electric cylinder 204 drives the stamping plate 201 to descend and then ascend, the upper die and the punch are combined with the lower die and then released, and the aluminum alloy plate 600 is stamped into a required sheet metal blank 601;

[0052] The intermittent one-way conveying assembly 300 is symmetrically installed on the front and rear sides of the placing table 101 and is used for intermittently conveying the aluminum alloy plate 600 in one direction, comprising two horizontal screw rods 301 rotatably arranged on the side walls of the side plates 103, two horizontal slide rods 302 fixed on the side walls of the side plates 103, and mounting blocks 303 screw-coupled and driven on the rod bodies of the screw rods 301, wherein the thread directions of the two screw rods 301 are consistent, each of the mounting blocks 303 is symmetrically rotatably arranged on the upper and lower sides of the mounting block 303 and is provided with a clamping plate 304 for reciprocating and intermittently clamping and conveying the aluminum alloy plate 600, and the side of the two clamping plates 304 close to each other on the same side of the front and rear sides is provided with a horizontal clamping groove 305; the width of the aluminum alloy plate 600 is greater than the width of the placing table 101, so that the outer edges of the aluminum alloy plate 600 protrude, facilitating the clamping and conveying of the slide rods 302.

[0053] The clamping plate 304 comprises a clamping piece 306 arranged on the side close to the aluminum alloy plate 600, and a spring 307 is hingedly arranged on the other side of the clamping plate 304, and the other end of the spring 307 is hingedly arranged on the mounting block 303; when the two clamping plates 304 on the same side of the front and rear sides are only subjected to the force of the spring 307, the two clamping pieces 306 on the other end of the two clamping plates 304 clamp the outer sides of the upper and lower surfaces of the aluminum alloy plate 600, and if the mounting block 303 moves at this time, the aluminum alloy plate 600 will be conveyed; the side of the clamping piece 306 facing the aluminum alloy plate 600 is provided with an antiskid pad 308, which improves the frictional force of contact when the clamping piece 306 clamps the aluminum alloy plate 600.

[0054] The side wall of the mounting block 303 is provided with a first sliding hole 309 for the rod body of the slide rod 302 to slide through, the inner side of the first sliding hole 309 is provided with a third linear bearing, the third linear bearing is sleeved on the outer side of the rod body of the slide rod 302, and the mounting block 303 is provided with a screw hole 310 for the rod body of the screw rod 301 to screw through; when the screw rod 301 rotates, the mounting block 303 cannot rotate due to the limitation of the slide rod 302, so it will move along the directions of the rod bodies of the screw rod 301 and the slide rod 302, and the slide rods 302 on the front and rear sides are provided with at least two slide rods 302, so as to ensure that the mounting block 303 cannot rotate around the slide rods 302, but only moves horizontally along the two slide rods 302;

[0055] The adjusting assembly 400 is installed at a distance on the left and right sides of the clamping plate 304, comprising an "L"-shaped follower plate 401 sliding on the rod body of the slide rod 302, the follower plate 401 is located on the left side of the clamping plate 304, and the end of the follower plate 401 close to the clamping plate 304 protrudes and is provided with a clamping plate 402, and 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 card slots 305 on the same side of the front and back, the distance between the two clamping plates 304 on the same side of the front and back is expanded, 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, when the mounting block 303 moves close to the left side plate 103, the two clamping plates 304 will touch the clamping plate 402, when the mounting block 303 continues to move to the left, the clamping plate 402 will be inserted into the card slot 305, thereby expanding the distance between the two clamping plates 304 on the same side of the front and back, 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 edges of the card slot 305 and the outer edges of the clamping plate 402 are chamfered, so that when they contact, the clamping plate 402 is better inserted into the card slot 305;

[0057] Wherein the left side wall of the two right side plates 103 is fixedly provided with an ejection plate 403 aligned with the clamping plate 402, the width of the upper and lower sides of the ejection plate 403 is always less than the distance between the two card slots 305 on the same side of the front and back, and the ejection plate 403 is used to eject the clamping plate 402 inserted into the card slot 305, thereby reducing the distance between the two clamping plates 304 on the same side of 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, because the spring 307 still applies a pushing force to the end of the clamping plate 304 at this time, the two clamping plates 304 will generate a clamping force on the clamping plate 402, so when the clamping plate 304 moves from left to right, it will also drive the follower plate 401 and the clamping plate 402 to slide left and right along the shaft body of the slide rod 302, and the side wall of the follower plate 401 is provided with a second sliding hole 404, and a fourth linear bearing is installed in the inner side of the second sliding hole 404, and the inner side of the fourth linear bearing slides on the outer side of the shaft body of the slide rod 302, so that the friction when the follower plate 401 and the clamping plate 402 slide is small, which is beneficial to the movement of the clamping plate 304, and because the two clamping plates 304 are separated by the clamping plate 402, the mounting block 303 cannot drive the aluminum alloy plate 600 to move when it moves from left to right, so it will not hinder the stamping of the aluminum alloy plate 600, and when the mounting block 303 moves close to the right side plate 103, the left end of the ejection plate 403 will touch the right end of the clamping plate 402, and when the mounting block 303 continues to move to the right, the ejection plate 403 will eject the clamping plate 402 from the card slot 305, thereby reducing the distance between the two clamping plates 304 on the same side of the front and back, so that the clamping plates 304 can clamp and convey the aluminum alloy plate 600;

[0058] When the two clamping plates 306 clamp the aluminum alloy plate 600, the distance between the two card slots 305 on the same side of the front and back is less than the thickness of the clamping plate 402; when the clamping plate 402 is pushed out of the inside of the card slot 305 by the ejection plate 403, and the mounting block 303 moves from right to left, the two clamping plates 304 will push the follow-up plate 401 to slide along the shaft of the slide rod 302 from right to left due to the small friction of the follow-up plate 401 and the thickness of the clamping plate 402 being greater than the distance between the two card slots 305. When the left side of the follow-up plate 401 hits the right side wall of the left side plate 103 and cannot move, the clamping plate 402 is inserted into the two card slots 305 on the same side of the front and back again, the distance between the two clamping plates 304 is expanded, and the clamping of the aluminum alloy plate 600 is released. Therefore, when the lead screw 301 rotates repeatedly, the clamping plates 304 realize intermittent reciprocating clamping and conveying of the aluminum alloy plate 600.

[0059] The linkage assembly 500 is installed on the stamping plate 201 and the base 102, and the stamping plate 201 is lifted at the same time to drive the intermittent one-way conveying assembly 300 to convey the aluminum alloy plate 600 intermittently and unidirectionally through the linkage assembly 500. The linkage assembly 500 includes a vertical rack 501 arranged on the front and back side walls of the stamping plate 201, a fixed frame 502 arranged on the front and back side walls of the base 102, a horizontal rotating rod 503 rotatably arranged on the side wall of the fixed frame 502, a follow-up gear 504 arranged on the shaft of the rotating rod 503 and meshing with the rack 501, two rotating directions of the follow-up gears 504 being consistent, and the right ends of the two rotating rods 503 driving the lead screw 301 to rotate through a speed change assembly 505.

[0060] The speed change assembly 505 includes a horizontal linkage rod 506 rotatably arranged on the fixed frame 502, a speed change gear one 507 and a speed change gear two 508 arranged on the shaft of the linkage rod 506, a speed change gear three 509 arranged on the shaft of the rotating rod 503 and meshing with the speed change gear one 507, the diameter of the speed change gear three 509 being greater than that of the speed change gear one 507, the left end of the lead screw 301 extending to rotate through the side wall of the left side plate 103 and being provided with a speed change gear four 510 meshing with the speed change gear two 508, the diameter of the speed change gear two 508 being greater than that of the speed change gear four 510. Since the number of rotations of the follow-up gear 504 driven by the rack 501 is limited when the rack 501 is lifted, the number of rotations of the lead screw 301 is sufficient for the clamping plates 304 to clamp the aluminum alloy plate 600 to move through the speed change assembly 505. It should be noted that after the speed change through the speed change assembly 505, the stamping plate 201 is lifted for one round trip, which is one round trip of the clamping plates 304, and the length conveyed by the clamping plates 304 is not less than the length required by one sheet metal blank 601.

[0061] An aluminum alloy wellhead cover processing and forming method, comprising the following steps:

[0062] Step 1, the stamping plate 201 is initialized at the highest point, and at this time the two clamping plates 304 are opened 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;

[0063] Step 2, when the stamping plate 201 descends, the rack 501 drives the follow-up gear 504 and the rotating rod 503 to rotate, and then the speed change assembly 505 drives the lead screw 301 to rotate clockwise;

[0064] Step 3, when the lead screw 301 rotates clockwise, the mounting block 303 moves from left to right, and since the two clamping plates 304 are opened by the clamping plate 402, the aluminum alloy plate 600 cannot be moved, and when the mounting block 303 moves to the side plate 103 close to the right side, the left end of the ejection plate 403 touches the right end of the clamping plate 402, and when the mounting block 303 continues to move to the right, the clamping plate 402 is ejected from the clamping groove 305, so that the distance between the two clamping plates 304 on the same side is reduced, and the two clamping plates 304 clamp the aluminum alloy plate 600;

[0065] Step 4, while the two clamping plates 304 clamp the aluminum alloy plate 600, the upper die and the lower die are completely closed, and the aluminum alloy plate 600 is stamped into the required sheet metal blank 601;

[0066] Step 5, the electric cylinder 204 controls the stamping plate 201 to rise again, the rack 501 drives the follow-up gear 504 and the rotating rod 503 to rotate counterclockwise, and then the speed change assembly 505 drives the lead screw 301 to rotate counterclockwise;

[0067] Step 6, when the lead screw 301 rotates counterclockwise, the mounting block 303 moves from right to left, and since the two clamping plates 304 clamp the aluminum alloy plate 600 at this time, the aluminum alloy plate 600 can be clamped and conveyed, and in the process of moving the two clamping plates 304, the follow-up plate 401 will be pushed to slide along the rod body of the slide rod 302 from right to left, until the left side of the follow-up plate 401 touches the right side wall of the left side plate 103 and cannot move, and at this time 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 again, the distance between the two clamping plates 304 is expanded, and the clamping of the aluminum alloy plate 600 is released, so that the lead screw 301 is repeatedly rotated, the clamping plate 304 realizes intermittent clamping and conveying of the aluminum alloy plate 600, and the aluminum alloy plate 600 is gradually stamped into the required sheet metal blank 601.

9. A method for processing and forming aluminum alloy manhole cover, implemented by the aluminum alloy manhole cover processing and forming device as described in claim 8, characterized in that: Includes the following steps: Step 1: When the stamping plate (201) is initialized, it is at the highest point, and the two clamping plates (304) are opened by the clamping plate (402). The aluminum alloy sheet (600) to be processed is placed on the top of the lower mold. The electric cylinder (204) is started to control the stamping plate (201) to drive the upper mold and punch to descend. Step 2: As the stamping plate (201) descends, the rack (501) drives the follower gear (504) to rotate and the rotating rod (503) to rotate, and then the speed change assembly (505) drives the lead screw (301) to rotate clockwise. Step 3: When the lead screw (301) rotates clockwise, it drives the mounting block (303) to move from left to right. Since the two clamping plates (304) are spread 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 right side plate (103), 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 push the clamping plate (402) out of the 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: While the two clamping plates (304) are holding the aluminum alloy sheet (600), the upper and lower molds are completely closed, and the aluminum alloy sheet (600) is stamped 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 lead screw (301) to rotate counterclockwise through the speed change assembly (505); Step 6: When the lead screw (301) rotates counterclockwise, it drives the mounting block (303) to move from right to left. Since the two clamping plates (304) are clamping the aluminum alloy plate (600), the aluminum alloy plate (600) can be clamped and transported. During the movement of the two clamping plates (304), they will touch and push the follower plate (401) to slide along the slide bar (302) from right to left until the left side of the follower plate (401) hits the right side of the left side plate (103). After the side wall can no longer move, the clamping plate (304) continues to move to the left, and the clamping plate (402) will be inserted into the two slots (305) on the same side. The distance between the two clamping plates (304) widens, and the clamping of the aluminum alloy plate (600) is released. Therefore, when the lead screw (301) rotates repeatedly, the clamping plate (304) intermittently clamps and transports the aluminum alloy plate (600), thereby gradually stamping the aluminum alloy plate (600) into the required sheet metal blank (601).
