[0021] refer to Figure 1 , Figure 2 and Figure 4 The metal sheet stamping equipment according to the embodiment of the present invention includes a frame 100, a stamping device 200, a conveying track 110, a feeding device 500, an interval conveying device 600 and a waste collecting device 400.

[0022] The punching device 200 is used to punch metal sheets, the conveying track 110 is parallel to the front-to-back direction, the front end of the conveying track 110 is arranged in front of the punching device 200, and the conveying track 110 is used to supply multiple metal sheets to move along the front-to-back direction. The feeding device 500 is arranged on the frame 100, and the feeding device 500 is used to accommodate multiple metal sheets and feed the multiple metal sheets into the conveying track 110 in sequence.

[0023] The spacing conveyor 600 is arranged on the frame 100, and is used to keep the multiple metal sheets on the conveying track 110 spaced apart from each other, and push the multiple metal sheets to move to the punching device 200 from the back to the front, so that the punching device 200 can punch the metal sheets, and the spacing conveyor 600 can push the scraps formed at the punching device 200 forward, so that the scraps can fall from the front end of the conveying track 110. The waste collection device 400 is arranged on the frame 100, and is used to collect the scraps that fall from the front end of the conveying track 110.

[0024] The punching device 200 is disposed on the frame 100, and the punching device 200 can punch the metal sheet moved to the punching device 200, so as to punch out a workpiece of a specified shape on the metal sheet and form scraps. The punching device 200 is a common punching die, and the punching die includes an upper die 210 and a lower die 220, the lower die 220 can support the metal sheet, and the upper die 210 can be molded with the lower die 220, so that the upper die 210 and the lower die 220 can punch out a workpiece on the metal sheet, and scraps are left on the lower die 220.

[0025] The conveying track 110 is arranged on the frame 100, and the front end of the conveying track 110 is arranged in front of the punching device 200, that is, the front end of the conveying track 110 is arranged in front of the lower mold 220. On the one hand, the conveying track 110 guides the plurality of metal sheets, so that the metal sheets on the conveying track 110 can be distributed in the front-to-back direction, and the plurality of metal sheets can move in the front-to-back direction on the conveying track 110. On the other hand, the front end of the conveying track 110 is arranged in front of the punching device 200, so that the conveying track 110 can also guide the scraps formed by the punching, so that the scraps can move in the front-to-back direction under the action of the conveying track 110 and can fall from the front end of the conveying track 110. The waste collection device 400 is installed on the frame 100, and the waste collection device 400 can collect the scraps falling from the front end of the conveying track 110 to prevent the falling scraps from interfering with the normal operation of the metal sheet punching equipment, and also ensure the cleanliness of the processing environment.

[0026] The feeding device 500 is arranged on the frame 100. The feeding device 500 plays the role of accommodating and feeding. It can not only accommodate multiple metal sheets, but also feed multiple metal sheets onto the conveying track 110 in sequence. The feeding device 500 may include a circular vibration feeder and a straight vibration feeder, and the output end of the circular vibration feeder is connected to the input end of the straight vibration feeder. The circular vibration feeder can accommodate multiple metal sheets and drive multiple metal sheets to move into the straight vibration feeder. The straight vibration feeder can drive multiple metal sheets to move from back to front, so that multiple metal sheets in the straight vibration feeder can be moved to the conveying track 110 in sequence. The circular vibration feeder and the straight vibration feeder are common feeders, which will not be further described here.

[0027] The spacing conveying device 600 is arranged on the frame 100. The spacing conveying device 600 can not only keep the multiple metal sheets on the conveying track 110 spaced from each other, but also push the multiple metal sheets on the conveying track 110 to move from the back to the front, so that the multiple metal sheets can be moved to the punching device 200 in sequence, and then the punching device 200 can punch the metal sheets. On the other hand, the spacing conveying device 600 can also push the scraps formed at the punching device 200 forward, so that the scraps can fall from the front end of the conveying track 110 into the waste collection device 400. The spacing conveying device 600 can include a first cylinder, a second cylinder, a third cylinder and a conveying belt. The first cylinder, the second cylinder and the third cylinder are arranged on the frame 100 in sequence from the back to the front, and the first cylinder and the second cylinder are arranged at the rear end of the conveying track 110, the third cylinder is arranged at the punching device 200, and the conveying belt can be rotatably connected to the conveying track 110.

[0028] Under the action of the feeding device 500, multiple metal sheets move to the rear end of the conveyor belt in sequence, and the conveyor belt can rotate and drive the multiple metal sheets to move from the back to the front. The piston rod of the second cylinder extends to the top of the conveyor belt and abuts against the first metal sheet in front of the multiple metal sheets. At this time, the piston rod of the second cylinder prevents the multiple metal sheets from continuing to move forward. Then the piston rod of the first cylinder extends to the top of the conveyor belt, and the piston rod of the first cylinder is inserted between the first metal sheet and the second metal sheet, so that the first metal sheet is between the piston rod of the first cylinder and the piston rod of the second cylinder. Then the piston rod of the second cylinder leaves the top of the conveyor belt, and the piston rod of the second cylinder no longer blocks the first metal sheet. The first metal sheet begins to continue to move toward the stamping device 200 under the action of the conveyor belt.

[0029] After the first metal sheet continues to move forward a certain distance, the piston rod of the second cylinder extends to the top of the conveyor belt again, and then the piston rod of the first cylinder moves away from the top of the conveyor belt. The second metal sheet and other metal sheets continue to move forward, and the second metal sheet abuts against the piston rod of the second cylinder. The piston rod of the second cylinder prevents the remaining metal sheets from moving forward, and the piston rod of the first cylinder extends to the top of the conveyor belt again and is inserted between the second metal sheet and the third metal sheet, so that the second metal sheet is between the piston rod of the first cylinder and the piston rod of the second cylinder, and then the piston rod of the second cylinder leaves the top of the conveyor belt, and the second metal sheet begins to move toward the stamping device 200 under the action of the conveyor belt, and so on, so that the multiple metal sheets on the conveyor belt can be spaced apart from each other, so that the multiple metal sheets on the conveyor belt can be moved to the stamping device 200 in sequence. In the embodiment of the present invention, the plurality of metal sheets being spaced apart from each other means that there is a gap between any two adjacent metal sheets, that is, any two adjacent metal sheets do not abut against each other.

[0030] After the metal sheet moves to the punching device 200, the punching device 200 punches the metal sheet to process the workpiece and form scraps. After the punching device 200 completes the punching, the piston rod of the third cylinder extends and pushes the scraps formed at the punching device 200, so that the scraps fall from the front end of the conveying track 110 and fall into the waste collection device 400.

[0031] It is understandable that the feeding device 500 can accommodate multiple metal sheets, and the feeding device 500 can also feed multiple metal sheets into the conveying track 110 in sequence. The conveying track 110 guides the multiple metal sheets, so that the multiple metal sheets can move in the front-back direction. After the feeding device 500 feeds the multiple metal sheets into the conveying track 110, the spacing conveying device 600 can not only keep the multiple metal sheets on the conveying track 110 spaced from each other, but also push the multiple metal sheets on the conveying track 110 to move from back to front, so that the multiple metal sheets on the conveying track 110 can move to the stamping device 200 in sequence. After the metal sheet moves to the stamping device 200, the stamping device 200 stamps the metal sheet to process a workpiece of a specified shape. At the same time, there are scraps left on the stamping device 200. In the process of the spacing conveyor 600 pushing the multiple metal sheets forward, the spacing conveyor 600 can also push the scraps at the punching device 200 forward, so that the scraps can be pushed and fall from the front end of the conveying track 110, and then the waste collecting device 400 can collect the scraps formed at the punching device 200. On the one hand, the spacing conveyor 600 in the metal sheet punching device can keep the multiple metal sheets on the conveying track 110 spaced apart from each other, avoiding the accumulation of the multiple metal sheets due to close proximity to each other, and reducing the possibility of the accumulation of the multiple metal sheets. On the other hand, the interval conveying device 600 can push the scraps at the stamping device 200 after the stamping is completed, so that the scraps stuck on the stamping device 200 can be pushed into the waste collection device 400, avoiding the accumulation of multiple metal sheets due to the stuck scraps, further reducing the possibility of accumulation of multiple metal sheets, allowing the metal sheet stamping equipment to operate normally for a long time, which is beneficial to reduce the failure rate of the metal sheet stamping equipment.

[0032] refer to Figure 1 and Figure 3 The metal sheet stamping equipment also includes a finished product collecting device 300. The stamping device 200 includes a lifting drive mechanism 230, a lower mold 220 and an upper mold 210. The lifting drive mechanism 230 is arranged on the frame 100. The upper mold 210 is connected to the output end of the lifting drive mechanism 230. The lower mold 220 is arranged on the frame 100. The upper surface of the lower mold 220 is used to support the metal sheet. The upper mold 210 is provided with a forming block. The lower mold 220 is provided with a forming hole 221 that cooperates with the forming block. The metal sheet can move to the top of the forming hole 221. The finished product collecting device 300 is arranged on the frame 100 and below the forming hole 221. The lifting drive mechanism 230 can drive the upper mold 210 to descend and close the mold with the lower mold 220, so that the forming block punches out a workpiece on the metal sheet, and the workpiece passes through the forming hole 221 and falls into the finished product collecting device 300.

[0033] It is understandable that, under the action of the interval conveying device 600, multiple metal sheets move from back to front on the conveying track 110, and multiple metal sheets can be moved to the upper surface of the lower mold 220 in sequence, and move to the top of the forming hole 221 in sequence. Then the lifting drive mechanism 230 drives the upper mold 210 to descend, so that the upper mold 210 is molded with the lower mold 220, and the forming block on the upper mold 210 begins to squeeze the metal sheet. After the upper mold 210 descends to a certain extent, the forming block is inserted into the forming hole 221, and the inner wall of the forming block and the forming hole 221 plays a shearing role on the metal sheet, so that the metal sheet is punched out of the workpiece, and the workpiece passes through the forming hole 221 and falls into the finished product collection device 300. The formed scraps remain on the upper surface of the lower mold 220, and the interval conveying device 600 can push the scraps on the upper surface of the lower mold 220, so that the scraps are pushed into the waste collection device 400. The forming block and the forming hole 221 are common structures in the punching device 200, and the shapes of the forming block and the forming hole 221 are the same as the workpiece, which will not be further described here. The lifting drive mechanism 230 is also a common mechanism that can provide up and down power, which will not be further described here.

[0034] refer to Figure 3 The finished product collecting device 300 includes a first conveyor belt 310 and a finished product box 320. The first conveyor belt 310 is parallel to the front-to-back direction. The first conveyor belt 310 can be rotatably connected to the frame 100. The first conveyor belt 310 is used to convey the workpiece from the back to the front. The rear end of the first conveyor belt 310 is arranged below the forming hole 221 so that the workpiece falling from the forming hole 221 can fall on the first conveyor belt 310. The finished product box 320 is arranged below the front end of the first conveyor belt 310 so that the workpiece falling from the front end of the first conveyor belt 310 can fall into the finished product box 320. It can be understood that after the workpiece is punched out on the metal sheet, the workpiece will pass through the forming hole 221 and fall on the first conveyor belt 310. The first conveyor belt 310 can convey the workpiece from the back to the front. After the workpiece moves forward a certain distance, the workpiece will fall from the front end of the first conveyor belt 310 into the finished product box 320 to achieve the purpose of collecting the workpiece. As an embodiment of the present invention, the finished product box 320 can be detachably connected to the frame 100, so that an operator can remove the finished product box 320 from the frame 100, so that the operator can carry the finished product box 320 and multiple workpieces in the finished product box 320.

[0035] refer to Figure 2 , Figure 4 , Figure 6 and Figure 7The conveying track 110 includes a support plate 111 and two limit plates 112. The support plate 111 is arranged on the frame 100. The support plate 111 is arranged behind the lower mold 220. The upper surface of the support plate 111 is flush with the upper surface of the lower mold 220. The two limit plates 112 are parallel to the front-to-back direction. The two limit plates 112 are connected to the upper surfaces of the support plate 111 and the lower mold 220. The front ends of the two limit plates 112 are arranged in front of the lower mold 220. The forming holes 221 are arranged on the two limit plates. Between the limiting plates 112, the area between the two limiting plates 112 is used for multiple metal sheets to move along the front-to-back direction. The interval conveying device 600 can drive the multiple metal sheets between the two limiting plates 112 to move from back to front, so that the multiple metal sheets on the support plate 111 can be moved to the top of the forming hole 221 in sequence. The feeding device 500 is arranged behind the two limiting plates 112, so that the feeding device 500 can feed the multiple metal sheets into the area between the two limiting plates 112 in sequence.

[0036] It can be understood that the upper surfaces of the support plate 111 and the lower mold 220 can both support the metal sheet, that is, the metal sheet can move on the upper surfaces of the support plate 111 and the lower mold 220. And the upper surface of the support plate 111 is flush with the upper surface of the lower mold 220, that is, the metal sheet on the support plate 111 can move to the upper surface of the lower mold 220. The two limiting plates 112 are parallel to the front-to-back direction and are connected to the upper surfaces of the support plate 111 and the lower mold 220, so that the two limiting plates 112 can play a limiting and guiding role on the metal sheet on the support plate 111 and the lower mold 220, thereby allowing the metal sheet on the support plate 111 and the lower mold 220 to move only in the front-to-back direction.

[0037] The feeding device 500 is disposed behind the two limit plates 112. The feeding device 500 can sequentially feed multiple metal sheets into the area between the two limit plates 112, so that the multiple metal sheets in the feeding device 500 are sequentially moved to the upper surface of the support plate 111. In the process of the feeding device 500 driving the multiple metal sheets to enter between the two limit plates 112 in sequence, the spacing conveying device 600 drives the multiple metal sheets between the two limit plates 112 to move from the back to the front, so that the multiple metal sheets on the support plate 111 can be sequentially moved forward to the top of the forming hole 221 on the lower mold 220. After the metal sheet moves to the top of the forming hole 221, the lifting drive mechanism 230 drives the upper mold 210 to descend and close to the lower mold 220, so that the forming block punches out a workpiece on the metal sheet, and the workpiece passes through the forming hole 221 and falls on the finished product collection device 300, and there are scraps left on the area of ​​the lower mold 220 corresponding to the forming hole 221, and the scraps are arranged between the two limit plates 112. After one of the workpieces is processed, the interval conveying device 600 continues to drive the multiple metal sheets between the two limit plates 112 from back to front. In the process of the interval conveying device 600 driving the multiple metal sheets between the two limit plates 112 to move forward, the interval conveying device 600 also drives the scraps between the two limit plates 112 to move forward, so that the scraps can fall from the front end of the two limit plates 112 and fall on the waste collection device 400.

[0038] refer to Figure 1 and Figure 3 The waste collection device 400 includes a second conveyor belt 410 and a waste box 420. The second conveyor belt 410 is parallel to the front-to-back direction. The second conveyor belt 410 is rotatably connected to the frame 100. The second conveyor belt 410 is used to convey the scraps from the back to the front. The rear end of the second conveyor belt 410 is arranged below the front end of the conveying track 110 so that the scraps dropped from the front end of the conveying track 110 can fall on the second conveyor belt 410. The waste box 420 is arranged below the front end of the second conveyor belt 410 so that the scraps dropped from the front end of the second conveyor belt 410 can fall into the waste box 420. The rear end of the second conveyor belt 410 is arranged below the front end of the conveying track 110, that is, the rear end of the second conveyor belt 410 is arranged below the front end of the two limit plates 112, so that the scraps dropped from the front end of the two limit plates 112 can fall on the rear end of the second conveyor belt 410. The principles of the waste collection device 400 and the finished product collection device 300 are similar and will not be further described here.

[0039] refer to Figures 4 to 6The feeding device 500 includes a linear cylinder 510, a push plate 520 and two enclosures 530. The two enclosures 530 are parallel to the up and down directions. The two enclosures 530 are connected to the frame 100. The two enclosures 530 are arranged behind the two limit plates 112. The two enclosures 530 are surrounded by a receiving cavity, which is used for stacking multiple metal sheets. The cylinder body of the linear cylinder 510 is connected to the frame 100 and is arranged behind the two enclosures 530. The piston rod of the linear cylinder 510 is connected to the push plate 520. The piston rod of the linear cylinder 510 can extend out and drive the push plate 520 to insert into the lower end of the receiving cavity, so that the push plate 520 pushes the metal sheet located at the bottom of the receiving cavity into the area between the two limit plates 112. The piston rod of the linear cylinder 510 can retract and drive the push plate 520 to be pulled out of the receiving cavity.

[0040] It is understandable that the two enclosures 530 are arranged to form a receiving chamber, and a plurality of metal sheets are stacked in the receiving chamber. When feeding is required, the piston rod of the linear cylinder 510 extends and drives the push plate 520 to move forward. In the process of the push plate 520 moving forward, the front end of the push plate 520 passes through the gap between the two enclosures 530 and is inserted into the lower end of the receiving chamber, so that the push plate 520 can push the metal sheet at the bottom of the receiving chamber forward and push the metal sheet into the area between the two limit plates 112. After the push plate 520 pushes one of the metal sheets into the area between the two limit plates 112, the piston rod of the linear cylinder 510 retracts and drives the push plate 520 to move backward, so that the push plate 520 can be pulled out of the receiving chamber. After the push plate 520 is pulled out of the receiving chamber, the plurality of metal sheets stacked in the receiving chamber will move downward under their own gravity and rest against the support plate 111 again, so that the push plate 520 can push the next metal sheet. By repeating the above process, the piston rod of the linear cylinder 510 is repeatedly extended and retracted, so that the push plate 520 can push the multiple metal sheets in the accommodating cavity into the area between the two guide plates in sequence.

[0041] refer to Figure 5 and Figure 6 The two enclosures 530 each include a baffle plate 531, a first bar 532 and a second bar 533. The two baffle plates 531 are both connected to the frame 100. The two first bars 532 are respectively arranged on the opposite side of the two baffle plates 531, and the two second bars 533 are respectively arranged on the front sides of the two baffle plates 531. The two baffle plates 531, the two first bars 532 and the two second bars 533 are surrounded by a receiving cavity. The gap between the two second bars 533 and the support plate 111 is used for the front end of the push plate 520 and a single metal sheet to pass through. The two first bars 532 are both configured to be adjustable in position in the front-to-back direction to adjust the length of the receiving cavity in the front-to-back direction. The two second bars 533 are both configured to be adjustable in position in the up-down direction to adjust the gap height between the two second bars 533 and the support plate 111.

[0042] It is understandable that the width and height of metal sheets of different specifications are different. In the embodiment of the present invention, the two first bars 532 are configured to be adjustable in the front-to-back direction of the baffle 531. By adjusting the positions of the two first bars 532 in the front-to-back direction of the two baffles 531, the length of the accommodating cavity in the front-to-back direction can be changed, so that the accommodating cavity can accommodate metal sheets of different width specifications. In the embodiment of the present invention, the gap height between the two second bars 533 and the support plate 111 is between one times the thickness of the metal sheet and two times the thickness of the metal sheet, so that the push plate 520 can only push out the metal sheet at the bottom of the accommodating cavity each time. The two second bars 533 are configured to be adjustable in the up-down direction of the baffle 531. By adjusting the positions of the two second bars 533 in the up-down direction of the two baffles 531, the gap height between the two second bars 533 and the support plate 111 can be adjusted to accommodate metal sheets of different thickness specifications. In the embodiment of the present invention, the first gear bar 532 and the second gear bar 533 are both positionally adjustable through the structure of waist-shaped holes and bolts, which will not be further described here.

[0043] refer to Figure 4 and Figures 6 to 10The metal sheet stamping equipment also includes a transmission device 700. The interval conveying device 600 includes a first transmission shaft, a second transmission shaft, two first sprocket wheels 610, two second sprocket wheels 620, two chains 630 and a plurality of push rods 640. The two first sprocket wheels 610 are rotatably connected to the frame 100. The two first sprocket wheels 610 are respectively arranged on the left and right sides of the rear ends of the two limiting plates 112. The two first sprocket wheels 610 are connected by the first transmission shaft. The two second sprocket wheels 620 are rotatably connected to the frame 100. The two second sprocket wheels 620 are respectively arranged on the left and right sides of the front ends of the two limiting plates 112. The two second sprocket wheels 620 are connected by the second transmission shaft. One chain 630 is wound around the first sprocket wheel 610 and the second sprocket wheel 620 on the left side, and the other chain 630 is wound around the first sprocket wheel 610 and the second sprocket wheel 620 on the right side. On the sprocket 610 and the second sprocket 620, the upper parts of the two chains 630 are parallel to the front-to-back direction and are arranged above the two limit plates 112, and the multiple push rods 640 are parallel to the left-to-right direction. The left and right ends of the multiple push rods 640 are respectively connected to the two chains 630, and the multiple push rods 640 on the upper part of the chain 630 are arranged above the two limit plates 112. The area between any two adjacent push rods 640 on the upper part of the chain 630 is used to accommodate metal sheets. The piston rod of the linear cylinder 510 can only drive one of the first sprockets 610 to rotate through the transmission device 700 when it is extended, so that the push plate 520 pushes the metal sheet between the two push rods 640 at the rear end of the two limit plates 112, and the multiple push rods 640 on the upper part of the chain 630 push the scraps and multiple metal sheets between the two limit plates 112 forward respectively.

[0044] In the embodiment of the present invention, reference Figure 2 and Figure 6 The thickness of the two limiting plates 112 is smaller than the thickness of the metal sheet, so that the upper part of the metal sheet can extend from between the two limiting plates 112 and abut against the push rod 640. Figure 8, the shaded portion on the chain 630 in the figure is the upper portion of the chain 630. The two push rods 640 with shades in the figure are the two push rods 640 at the rear ends of the two limit plates 112. In the embodiment of the present invention, a plurality of push rods 640 are evenly distributed on the two chains 630, and the distance between any two adjacent push rods 640 on the upper portion of the chain 630 is greater than the width of the metal sheet. It is understandable that the two first sprockets 610 are both rotatably connected to the frame 100, and the two first sprockets 610 are connected by a first transmission shaft, so that when one of the first sprockets 610 rotates, the other first sprocket 610 will rotate synchronously. The two second sprockets 620 are both rotatably connected to the frame 100, and the two second sprockets 620 are connected via a second transmission shaft. Since one chain 630 is wound around the first sprocket 610 and the second sprocket 620 on the left side, and the other chain 630 is wound around the first sprocket 610 and the second sprocket 620 on the right side, when one of the first sprockets 610 rotates, the other first sprocket 610 and the two second sprockets 620 can rotate synchronously. For the convenience of explanation, it is defined that when the two first sprockets 610 and the two second sprockets 620 rotate synchronously, the upper part of the chain 630 moves from back to front, that is, the multiple push rods 640 on the upper part of the chain 630 move from back to front. The area between any two adjacent push rods 640 on the upper part of the chain 630 can accommodate the metal sheet, and when the multiple push rods 640 on the upper part of the chain 630 move forward, the push rods 640 can abut against the metal sheet in front of them, so that the push rods 640 can push forward the metal sheet between the two limit plates 112. Similarly, after the punching device 200 punches out the workpiece, there will be leftovers on the lower die 220, and the leftovers are located between the two limit plates 112, so that the push rods 640 on the lower die 220 that move forward can also push the leftovers forward.

[0045] When feeding is required, the piston rod of the linear cylinder 510 will extend, and the extended piston rod will drive the push plate 520 to move forward. At the same time, the extended piston rod drives one of the first sprockets 610 to rotate forward through the transmission device 700. During the forward movement of the push plate 520, the metal sheet at the bottom of the push plate 520 accommodation chamber at the front end of the push plate 520 moves forward, so that the metal sheet approaches the two limit plates 112. At the same time, the two first sprockets 610 and the two second sprockets 620 rotate forward synchronously, and the multiple push rods 640 on the upper part of the chain 630 begin to move forward, so that the multiple push rods 640 on the upper part of the chain 630 begin to push the scraps and multiple metal sheets between the two limit plates 112 forward.

[0046] The piston rod of the linear cylinder 510 continues to extend, and the push plate 520 begins to push the metal sheet into between the two limit plates 112. As the chain 630 rotates, the metal sheet pushed by the push plate 520 gradually enters between the two push rods 640 at the rear ends of the two limit plates 112. At the same time, the multiple push rods 640 on the upper part of the chain 630 continue to push the scraps and multiple metal sheets between the two limit plates 112 forward, so that the scraps between the two limit plates 112 continue to move forward to the front ends of the two limit plates 112, and the multiple metal sheets between the two limit plates 112 continue to move forward to the forming holes 221 on the lower mold 220.

[0047] When the piston rod of the linear cylinder 510 extends to the limit position, the metal sheet pushed by the push plate 520 completely enters between the two push rods 640 at the rear end of the two limit plates 112. At the same time, the next metal sheet is pushed to the top of the forming hole 221 by the push rod 640, and the residual scraps on the lower mold 220 are pushed down into the waste collection device 400 by the push rod 640. Then the piston rod of the linear cylinder 510 begins to retract, so that the push plate 520 is withdrawn from the accommodating cavity for the next push. Since the transmission device 700 can only drive one of the first sprockets 610 to rotate forward when the piston rod of the linear cylinder 510 extends, the two first sprockets 610 and the two second sprockets 620 remain different during the retraction of the piston rod of the linear cylinder 510, so that the multiple metal sheets between the two limit plates 112 remain motionless, so as to ensure that the forming block can smoothly punch the metal sheet above the forming hole 221. Repeating the above process can complete the feeding of metal sheets, stamping of metal sheets and removal of scraps. It can be seen that, on the one hand, the extension and retraction of the piston rod of the linear cylinder 510 can realize the feeding of metal sheets, so that the multiple metal sheets in the accommodating cavity can be pushed into the space between the two limit plates 112 in sequence. On the other hand, under the action of the transmission device 700, the linear cylinder 510 realizes the intermittent unidirectional transmission of one of the first sprockets 610, so that the multiple first sprockets 610 and the multiple second sprockets 620 can intermittently rotate forward, and then the multiple push rods 640 on the upper part of the chain 630 can push the multiple metal sheets between the two limit plates 112 to the top of the forming hole 221 in sequence, and can also make the scraps between the two limit plates 112 on the lower mold 220 be pushed into the waste collection device 400.

[0048] In the embodiment of the present invention, the stamping device 200 also includes a compression spring, a matching hole is provided on the upper mold 210, and the forming block is inserted into the matching hole. The upper mold 210 is connected to the output end of the lifting drive mechanism 230 through the compression spring. During the stamping process, the lifting drive mechanism 230 drives the upper mold 210 and the forming block to descend at the same time. The upper mold 210 will first be molded with the lower mold 220, and the compression spring begins to compress, so that the upper mold 210 and the lower mold 220 clamp the metal sheet. Then the forming block continues to descend, so that the forming block can stamp the metal sheet. The multiple push rods 640 on the upper part of the chain 630 move forward the same distance each time, that is, during the mold closing process of the upper mold 210, the relative positions of the upper mold 210 and the lower push rods 640 are the same. The upper mold 210 is provided with an avoidance groove 211 for the push rod 640 to extend into, so that after the upper mold 210 and the lower mold 220 are molded together, the push rod 640 can enter the avoidance groove 211 to prevent the push rod 640 from obstructing the upper mold 210 from being molded together with the lower mold 220.

[0049] refer to Fig. 9 and Fig.10 The transmission device 700 includes a connecting rod mechanism 710, a transmission wheel 720 and a one-way clutch 730. The transmission wheel 720 is connected to one of the first sprockets 610 through the one-way clutch 730. The piston rod of the linear cylinder 510 is connected to the transmission wheel 720 through the connecting rod mechanism 710, so that the piston rod extended from the linear cylinder 510 can drive the transmission wheel 720 to rotate, and the transmission wheel 720 drives one of the first sprockets 610 to rotate. The one-way clutch 730 is used to enable the transmission wheel 720 to only drive one of the first sprockets 610 to rotate in one direction. In the embodiment of the present invention, the piston rod of the linear cylinder 510 is connected to the transmission wheel 720 through the connecting rod mechanism 710. Under the action of the connecting rod mechanism 710, the linear motion of the piston rod of the linear cylinder 510 can be converted into the rotation of the transmission wheel 720.

[0050] refer to Fig. 9 and Fig.10The connecting rod mechanism 710 includes a first connecting rod, one end of which is hinged to the piston rod of the linear cylinder 510, and the other end of the first connecting rod is eccentrically hinged to the transmission wheel 720. The hinge between the first connecting rod and the transmission wheel 720 is located at the upper part of the transmission wheel 720 and does not coincide with the axis of the transmission wheel 720, that is, an eccentric connection. The connecting rod mechanism 710 is a common crank connecting rod mechanism 710 for changing linear motion into rotational motion, which will not be further described here. The transmission wheel 720 is connected to the input end of the one-way clutch 730, and one of the first sprockets 610 is connected to the output end of the one-way clutch 730. The one-way clutch 730 is a common clutch that only allows one-way rotation to transmit kinetic energy, and its specific structure will not be further described here. In the embodiment of the present invention, the one-way clutch 730 only allows the forward-rotating transmission wheel 720 to transmit power to one of the first sprockets 610 , that is, the one-way clutch 730 only allows the forward-rotating transmission wheel 720 to drive one of the first sprockets 610 to rotate forward.

[0051] It is understandable that when the piston rod of the linear cylinder 510 extends, the transmission wheel 720 starts to rotate forward under the power transmission of the connecting rod mechanism 710. At this time, the transmission wheel 720 drives one of the first sprockets 610 to rotate forward through the one-way clutch 730, thereby causing the two first sprockets 610 and the two second sprockets 620 to rotate synchronously. When the piston rod of the linear cylinder 510 retracts, the transmission wheel 720 starts to rotate reversely under the power transmission of the connecting rod mechanism 710. At this time, the one-way clutch 730 cuts off the power transmission between the transmission wheel 720 and the first sprocket 610, so that the two first sprockets 610 and the two second sprockets 620 remain stationary during the retraction of the piston rod of the linear cylinder 510.

[0052] refer to Figure 4, the left and right ends of the plurality of push rods 640 are respectively detachably connected to the two chains 630, the two first sprockets 610 are both configured to be adjustable in position in the front-to-back direction, and the linear cylinder 510 is configured to be adjustable in position in the front-to-back direction. When stamping is required for metal sheets of different specifications, the operator can first remove the plurality of push rods 640 from the two chains 630, and then remove the two chains 630 from the two first sprockets 610 and the two second sprockets 620. After the two chains 630 are removed, the operator can adjust the positions of the two first sprockets 610 in the front-to-back direction of the frame 100. After the positions of the two first sprockets 610 are adjusted, the operator rewinds the two chains 630 of corresponding lengths on the two first sprockets 610 and the two second sprockets 620. After the two chains 630 are installed, the operator can reinstall the multiple push rods 640 on the two chains 630 and adjust the gap distance between any two adjacent push rods 640 accordingly, so that the gap distance between the two push rods 640 can accommodate metal sheets of corresponding specifications. After the multiple push rods 640 are installed, the operator adjusts the position of the linear cylinder 510 in the front-to-back direction of the support plate 111, so that the push plate 520 can smoothly push the metal sheet between the two push rods 640.

[0053] It is understandable that the left and right ends of the multiple push rods 640 can be detachably connected to the two chains 630, so that the distance between the two push rods 640 is adjustable to accommodate metal sheets of different specifications. The positions of the two first sprockets 610 in the front-to-back direction of the frame 100 are adjustable, and the position of the linear cylinder 510 in the front-to-back direction of the frame 100 is adjustable, so that after replacing metal sheets of different specifications, the push plate 520 can still push the multiple metal sheets in the accommodating cavity into between the two limiting plates 112 in sequence, and the multiple push rods 640 can still push the multiple metal sheets to the top of the forming hole 221 in sequence, thereby improving the flexibility of the use of the metal sheet stamping equipment. In the embodiment of the present invention, the positions of the two limiting plates 112 in the left-right direction of the support plate 111 are adjustable to adjust the distance between the two limiting plates 112. As an embodiment of the present invention, the linear cylinder 510, the two first sprockets 610 and the two limit plates 112 are all positionally adjustable through the structure of waist-shaped holes and bolts, which will not be further described here.

[0054] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0055] Of course, the present invention is not limited to the above-mentioned embodiments, and those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention, and these equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
