Description

Technical Field

[0001] This invention relates to the field of punch presses, and more specifically to a shifting die double-punch punch press. Background Technology

[0002] Currently, the production of silicone rubber products often requires two punching processes. Specifically, in the first punching process, a deburring die is installed on the punch press, and then the workpiece is deburred. After the deburring is done, the workpiece is removed, the deburring die is removed and replaced with a product punching die, and then the workpiece is transferred to the lower die of the product punching die for further punching. Because the production process requires two punching processes and die changes, for the same punch press, the deburring die cannot be changed until the previous workpiece is punched out, resulting in a long time consumption and low efficiency in mass production. Moreover, during product production, operators must manually change the punching dies, and after the corresponding die is replaced, operators must manually load the workpiece onto the lower die of the corresponding punching die. This poses a significant safety hazard, as operators' hands may be injured by the upper die due to accidental collisions or machine malfunctions. Summary of the Invention

[0026] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0027] like Figure 1-8As shown, a shifting die double-punch press includes a frame 110, a loading station 120 formed on the frame 110, a lifting seat 211, a lifting drive device 212 for driving the lifting seat 211 to rise and fall, a burr punching station 130 formed on the frame 110, a burr punching upper die device 300 disposed on the lifting seat 211 and located at the burr punching station 130, a burr punching lower die 400 matching the burr punching upper die device 300, a product punching station 140 formed on the frame 110, a product punching upper die device 500 disposed on the lifting seat 211 and located at the product punching station 140, a product punching lower die 600 matching the product punching upper die device 500, a translation seat 221, and a translation drive device 222. The burr-cutting station 130 is located between the loading station 120 and the product-cutting station 140; the burr-cutting lower die 400 and the product-cutting lower die 600 are both fixed on the translation seat 221, and the translation drive device 222 is used to drive the translation seat 221 to reciprocate linearly to drive the burr-cutting lower die 400 to move back and forth between the loading station 120 and the burr-cutting station 130. When the burr-cutting lower die 400 is located at the loading station 120, the product-cutting lower die 600 is located at the burr-cutting station 130; when the burr-cutting lower die 400 is located at the burr-cutting station 130, the product-cutting lower die 600 is located at the product-cutting station 140; the burr-cutting upper die device 300 includes a vacuum adsorption seat 310 for vacuum adsorption of the workpiece.

[0028] In use, the translation drive device 222 can drive the translation seat 221 to move to the left, and drive the deburring die 400 to the loading station 120. The operator can load the workpiece onto the deburring die 400 at the loading station 120. Then, the translation drive device 222 can drive the translation seat 221 to move to the right, and drive the deburring die 400 to the deburring station 130. At this time, the lifting drive device 212 drives the lifting seat 211 to descend, so that the deburring die device 300 can descend and deburr the workpiece. After the deburring is completed, the workpiece is adsorbed by the vacuum adsorption seat 310 of the deburring die device 300, and the lifting drive device 212 drives the lifting seat 211 to descend. The workpiece rises along with the burr-cutting upper die 300, and then the translation drive 222 drives the translation seat 221 to move to the left. At this time, the burr-cutting lower die 400 moves to the loading station 120, and the product-cutting lower die 600 moves to the burr-cutting station 130. The operator can manually load the next workpiece onto the burr-cutting lower die 400. At the same time, the lifting drive 212 drives the lifting seat 211 to descend. At this time, the burr-cutting upper die 300 descends with the lifting seat 211 and releases the burr-cut workpiece onto the product-cutting lower die 600. Then, the lifting drive 212 drives the lifting seat 211 to rise, and then the translation drive 222 drives the translation seat 221 to move to the left. The shifting seat 221 moves to the right, causing the burr-cutting lower die 400 to move to the burr-cutting station 130 and the product-cutting lower die 600 to move to the product-cutting station 140. Then, the lifting drive device 212 drives the lifting seat 211 to descend. At this time, the product-cutting upper die device 500 cuts the workpiece on the product-cutting lower die 600 as the lifting seat 211 descends, and the burr-cutting upper die device 300 cuts the burrs on the next workpiece on the burr-cutting lower die 400 as the lifting seat 211 descends. Therefore, the burr-cutting operation of the next workpiece and the product-cutting operation of the previous workpiece can be performed synchronously without the need to change the cutting dies, thus saving time and improving efficiency. Moreover, by using the translation drive device 221... The translation of the translation seat 221 by the 22 drive can move the burr-cutting lower die 400 to the loading station 120 for loading. By reasonably setting the burr-cutting upper die device 300, and through the cooperation of the burr-cutting upper die device 300, lifting drive device 212, lifting seat 211, translation drive device 222, and translation seat 221, the burr-cut workpiece can also be transferred from the burr-cutting lower die 400 to the product burr-cutting lower die 600. This eliminates the need for operators to manually load the burr-cut workpiece onto the product burr-cutting lower die 600, thereby avoiding the risk of operator's hand being injured by the upper die during workpiece loading. This improves safety and reduces operator involvement and workload.

[0029] The burr-cutting upper die device 300 includes a first support base 320, a burr-cutting punch 330, and a first lifting device 340 fixed on a lifting base 211; the vacuum adsorption base 310 is movably mounted on the first support base 320, and a first elastic element 350 is provided between the vacuum adsorption base 310 and the first support base 320, the first elastic element 350 being used to provide an elastic force to cause the vacuum adsorption base 310 to move downward; the first support base 320 is located above the vacuum adsorption base 310; the vacuum adsorption base 310 is provided with a first through hole 311, the burr-cutting punch 330 is fixed on the first support base 320 and movably passes through the first through hole 311; the first lifting device 340 is provided on the lifting base 211 and is used to lift the vacuum adsorption base 310; the burr-cutting lower die 400 is provided with a burr through groove 410 for the burr-cutting punch 330 to pass through. In use, when the workpiece is placed on the deburring die 400 and the deburring die 400 is located at the deburring station 130, the lifting seat 211 descends under the drive of the lifting drive device 212. The deburring die device 300 descends with the lifting seat 211. When the vacuum adsorption seat 310 of the lifting seat 211 descends to press on the workpiece, the deburring punch 330 continues to descend with the lifting seat 211 to deburr the workpiece. During the deburring process, the deburring punch 330 remains inserted on the workpiece, thus providing an interference fit and positioning function. At the same time, the workpiece can be adsorbed by evacuating the vacuum adsorption seat 310. Thus, the workpiece can be fixed by both vacuum adsorption and interference fit to ensure the stability of the workpiece and prevent it from falling off or shifting. Then, the lifting drive device 212 drives the lifting seat 211 to descend. As the workpiece rises, the vacuum adsorption seat 310 is lifted by the first lifting device 340, so that the lower end of the burr punch 330 can remain exposed outside the vacuum adsorption seat 310 and be interference-fitted with the workpiece. When the product punching lower die 600 moves to the burr punching station 130 with the translation seat 221, the burr punching upper die device 300 descends with the lifting seat 211 and then separates from the vacuum adsorption seat 310 through the first lifting device 340. Under the elastic force of the first elastic element 350, the vacuum adsorption seat 310 moves downward relative to the burr punch 330, so that the lower end of the burr punch 330 is received in the first through hole 311 of the vacuum adsorption seat 310. The workpiece separates from the burr punch 330 as the vacuum adsorption seat 310 moves downward. At the same time, the workpiece can be released onto the product punching lower die 600 by passing gas through the vacuum adsorption seat 310.By combining a vacuum adsorption seat 310, a first support seat 320, a burr punch 330, a first elastic element 350, and a first lifting device 340 into the burr-cutting upper die device 300, the burr can be cut while the workpiece is being lifted. The workpiece can be fixed by both vacuum adsorption and interference fit to ensure the stability of the workpiece and to provide positioning, thus preventing workpiece displacement and ensuring the accuracy of subsequent product cutting.

[0030] In a further preferred embodiment of the present invention, the vacuum adsorption seat 310 is vertically and flexibly mounted on the first support seat 320 via a plurality of first connecting screws 360. The first support seat 320 is provided with a plurality of first movable slots corresponding one-to-one with the plurality of connecting screws. The upper end of the first connecting screw 360 is movably mounted in the corresponding first movable slot, and the lower end of the first connecting screw 360 is fixed on the vacuum adsorption seat 310, so that the vacuum adsorption seat 310 can be raised and lowered relative to the first support seat 320 with the first connecting screw 360. The first movable slot includes a first guide slot section and a first receiving slot section located above the first guide slot section and communicating with the first guide slot section. The first connecting screw 360 is movably inserted into the first guide slot section, and the end head of the first connecting screw 360 is located in the first receiving slot section. The cross-sectional area of ​​the end head of the first connecting screw 360 is larger than the cross-sectional area of ​​the first guide slot section, so that the end head of the first connecting screw 360 plays a limiting role to prevent the first connecting screw 360 from detaching from the first support seat 320.

[0031] To further improve efficiency, the number of the burr punches 330 can be set to multiple, with the number of the first through holes 311 and burr grooves 410 matching the number of the burr punches 330, thus enabling the punching of multiple burrs at once. In practical designs, to match the shape of some products, the multiple burr punches 330 can be divided into main burr punches and secondary burr punches of different sizes, thereby matching the shape of the corresponding product to punch out the main inner burr and secondary inner burr.

[0032] The first elastic element 350 is a first spring. The vacuum adsorption seat 310 is provided with a first lower embedding groove, and the first support seat 320 is provided with a first upper embedding groove. The upper end of the first spring is embedded in the first upper embedding groove, and the lower end is embedded in the first lower embedding groove. Of course, the first elastic element 350 can also be an elastic sleeve or other elastic element, but using a first spring as the first elastic element 350 is the optimal embodiment of the present invention, which can provide the corresponding elastic force while facilitating installation. In this embodiment, a plurality of first springs are provided between the first support seat 320 and the vacuum adsorption seat 310. The lower end of the vacuum adsorption seat 310 is provided with a plurality of first lower embedding grooves for the lower ends of the plurality of first springs to be embedded in, and the upper end of the first support seat 320 is provided with a plurality of first upper embedding grooves for the upper ends of the plurality of first springs to be embedded in.

[0033] The translation seat 221 is provided with a burr passing groove 223 that communicates with the burr passing groove 410. The shifting die double punch press also includes a burr collecting device 710. The frame 110 is provided with a burr guiding groove 111 located below the burr cutting station 130 and used to guide the burrs to the burr collecting device 710. The burrs punched by the burr punch 330 fall from the burr passing groove 410 and the burr passing groove 223 into the burr guiding groove 111, and then enter the burr collecting device 710 along the burr guiding groove 111. This eliminates the need for operators to manually collect the burrs, further reducing the workload of the operators.

[0034] In this embodiment, the burr collection device 710 is a burr collection frame to reduce costs.

[0035] The first lifting device 340 includes a first lifting seat 341 that is movably mounted on a lifting base 211, and a first lifting component 342 disposed on the lifting base 211 and used to drive the first lifting seat 341 to rise and fall. The lower ends of both sides of the first lifting seat 341 are provided with first supporting wings 343 for supporting the vacuum adsorption seat 310. In use, the first lifting component 342 drives the first lifting seat 341 to rise, which in turn drives the first supporting wings 343 to rise, thus lifting the vacuum adsorption seat 310 and keeping it elevated relative to the burr punch 330. Conversely, the first lifting component 342 drives the first lifting seat 341 to fall, causing the first supporting wings 343 to fall and separate from the vacuum adsorption seat 310, thereby removing the supporting force on the vacuum adsorption seat 310. This allows the vacuum adsorption seat 310 to fall back to its original position relative to the burr punch 330 under the elastic force of the first elastic element 350.

[0036] The first lifting component 342 includes a first lifting cylinder. The cylinder body of the first lifting cylinder is fixed on the lifting seat 211, and the piston rod of the first lifting cylinder is fixedly connected to the first lifting seat 341, thereby facilitating connection. Of course, in addition to this, the first lifting component 342 can also be a linear motor or the like, as long as it can drive the first lifting seat 341 to rise and fall. However, using a first lifting cylinder for the first lifting component 342 is the optimal embodiment of the present invention, as it facilitates connection.

[0037] The first lifting seat 341 includes a first top seat located above the lifting seat 211. One side of the first top seat is provided with a first front movable rod that is movably inserted into the lifting seat 211, and the other side is provided with a second rear movable rod that is movably inserted into the lifting seat 211. One of the two first supporting wings 343 is fixedly connected to the first front movable rod, and the other is fixedly connected to the second rear movable rod. The piston rod of the first lifting cylinder is fixedly connected to the first top seat of the first lifting seat 341. By adopting the above structure, the vacuum adsorption seat 310 can be stably lifted while reducing weight and facilitating connection.

[0038] Both sides of the vacuum adsorption seat 310 are provided with outwardly protruding first outwardly protruding supports for the first supporting wings 343. In a further preferred embodiment of the invention, the burr-cutting die 400 is provided with a forming cavity, and the vacuum adsorption seat 310 is provided with a forming boss for cooperating with the forming cavity. Thus, at the burr-cutting station 130, corresponding shapes can be formed according to the product requirements. The burr through groove 410 is located below the forming cavity and penetrates the inner bottom wall of the forming cavity. The vacuum adsorption seat 310 is provided with a vacuum adsorption channel, so that the workpiece can be vacuum adsorbed and released by evacuating the vacuum channel and introducing gas. The vacuum adsorption channel and the first through hole 311 both penetrate the lower surface of the forming boss.

[0039] The product punching upper die device 500 includes a second support base 510, a spring material base 520, a product punch 530, and a second lifting device 540 fixed on a lifting base 211. The spring material base 520 is movably mounted on the second support base 510, and a second elastic element 550 is provided between the spring material base 520 and the second support base 510. The second elastic element 550 is used to provide an elastic force to cause the spring material base 520 to move downward. The second support base 510 is located above the spring material base 520. A second through hole 521 is provided on the spring material base 520, and the product punch 530 is fixed on the second support base 510 and movably passes through the second through hole 521. The second lifting device 540 is provided on the lifting base 211 and is used to lift the spring material base 520. The product punching lower die 600 is provided with a product through groove 610 for the product punch 530 to pass through. In use, when the workpiece to be punched to remove burrs is placed on the lower die 600 and the lower die 600 is located at the punching station 140, the lifting seat 211 descends under the drive of the lifting drive device 212. The upper die device 500 descends with the lifting seat 211. When the spring seat 520 descends onto the workpiece, the product punch 530 continues to descend with the lifting seat 211 to punch out the product. After the product is punched out, the burrs (the remaining part of the workpiece) adhere to the product punch 530 due to interference fit or friction. Then, the lifting drive device 212 drives the lifting seat 211 to rise. At the same time, the product punch 500 descends with the lifting seat 211. The second lifting device 540 lifts the spring seat 520, so that the lower end of the product punch 530 can remain exposed outside the spring seat 520. Then, the second lifting device 540 separates from the spring seat 520, so that the spring seat 520 moves downward relative to the product punch 530 under the elastic force of the second elastic element 550 to push the outer burr downward. Depending on the firmness of the outer burr, the second lifting device 540 can lift the spring seat 520 multiple times and separate from the spring seat 520 each time, so that the outer burr can be pushed off the product punch 530 and fall downward with the help of the spring seat 520, thereby realizing the separation of the outer burr from the product punch 530. By combining the spring seat 520, the second support seat 510, the product punch 530, the second elastic element 550, and the second lifting device 540 into the product punching die device 500, the external burrs can be automatically separated from the product punch 530 while punching the product, preventing the external burrs from adhering to the product punch 530. This eliminates the need for manual separation by the operator, further reducing the workload. Moreover, since the product punching die device 500 and the burr punching die device 300 are raised and lowered synchronously, the lifting seat 211 and the lifting drive device 212 can be shared, eliminating the need to configure separate lifting drive devices 212 for the product punching die device 500 and the burr punching die device 300, which also reduces costs.

[0040] In a further preferred embodiment of the present invention, the spring seat 520 is vertically and elliptically mounted on the second support seat 510 via a plurality of second connecting screws 560. The second support seat 510 is provided with a plurality of second movable slots corresponding one-to-one with the plurality of connecting screws. The upper end of the second connecting screw 560 is movably mounted in the corresponding second movable slot, and the lower end of the second connecting screw 560 is fixed on the spring seat 520, so that the spring seat 520 can be raised and lowered relative to the second support seat 510 with the second connecting screw 560. The second movable slot includes a second guide slot section and a second receiving slot section located above the second guide slot section and communicating with the second guide slot section. The second connecting screw 560 is movably inserted into the second guide slot section, and the end head of the second connecting screw 560 is located in the second receiving slot section. The cross-sectional area of ​​the end head of the second connecting screw 560 is larger than the cross-sectional area of ​​the second guide slot section, so that the end head of the second connecting screw 560 plays a limiting role to prevent the second connecting screw 560 from detaching from the second support seat 510.

[0041] To further improve efficiency, when using multiple burr punches 330, the number of product punches 530 is set to be multiple accordingly. The number of the second through hole 521 and the product through groove 610 are the same as the number of product punches 530, so that multiple products can be punched at one time.

[0042] The second elastic element 550 is a second spring. The spring seat 520 is provided with a second lower embedding groove, and the second support seat 510 is provided with a second upper embedding groove. The upper end of the second spring is embedded in the second upper embedding groove, and the lower end is embedded in the second lower embedding groove. Of course, the second elastic element 550 can also be an elastic sleeve or other elastic element, but using a second spring as the second elastic element 550 is the optimal embodiment of the present invention, which can provide the corresponding elastic force while facilitating installation. In this embodiment, a plurality of second springs are provided between the second support seat 510 and the spring seat 520. The spring seat 520 is provided with a plurality of second lower embedding grooves for the lower ends of the plurality of second springs to be embedded, and the second support seat 510 is provided with a plurality of second upper embedding grooves for the upper ends of the plurality of springs to be embedded.

[0043] The translation seat 221 is provided with a product insertion slot 224 communicating with the product through slot 610. The shifting die double punch press also includes a product collection device 720. The frame 110 is provided with a product guide slot 112 located below the product punching station 140 and used to guide the product to the product collection device 720. The product punched by the product punch 530 falls from the product through slot 610 and the product insertion slot 224 into the product guide slot 112, and then enters the product collection device 720 along the product guide slot 112. This eliminates the need for operators to manually collect the products, further reducing the workload of the operators.

[0044] In this embodiment, the product collection device 720 is a product collection frame, which can reduce costs.

[0045] As a further preferred embodiment of the present invention, the product punch 530 is also provided with a positive pressure gas channel 531 for gas to be introduced. The positive pressure gas channel 531 penetrates the lower surface of the product punch 530. After the product punch 530 punches out the product, positive pressure gas is introduced into the positive pressure gas channel 531 to separate the product from the product punch 530 and drop it into the product guide groove 112 through the product through groove 610 and the product through groove 224. This can prevent the product from adhering to the product punch 530 due to friction.

[0046] One side of the frame 110 is provided with a first air blowing device 113 at the corresponding product punching station 140, and the other side of the frame 110 is provided with a burr guide cover 114 at the corresponding product punching station 140. The burr guide cover 114 is provided with a feed inlet facing the product punching station 140 and a burr guide cavity communicating with the feed inlet. When the outer burr separates from the product punch 530 and falls downwards, the air blowing by the first air blowing device 113 can blow the outer burr towards the burr guide cover 114 and enter the burr guide cavity through the feed inlet. Preferably, the burr guide cavity is used to guide the outer burr into the burr collection device 710, so that the outer burr entering the burr guide cavity can enter the burr collection device 710 along the burr guide cavity. In this embodiment, when the outer burr separates from the product punch 530 and falls downwards, the product punching die 600 is still in the product punching station 140 and does not move to the burr punching station 130 with the translation seat 221. At this time, the outer burr falls onto the product punching die 600 and is blown towards the burr guide cover 114 by the first air blowing device 113.

[0047] In this embodiment, the frame 110 is provided with a second air blowing device 115 at the corresponding burr punching station 130, wherein the first air blowing device 113 and the second air blowing device 115 are located on the same side of the frame 110. The top of the burr guide cover 114 is also provided with an oblique blowing device 116 with the blowing direction facing the burr guide cavity, so that the outer burr can be assisted to enter the burr guide cavity through the blowing action of the oblique blowing device 116.

[0048] The second lifting device 540 includes a second lifting seat 541 that is movably mounted on a lifting base 211, and a second lifting component 542 disposed on the lifting base 211 and used to drive the second lifting seat 541 to rise and fall. The lower ends of both sides of the second lifting seat 541 are provided with second supporting wings 543 for supporting the spring material seat 520. In use, the second lifting component 542 drives the second lifting seat 541 to rise, which in turn drives the second supporting wings 543 to rise, thus lifting the spring material seat 520 and keeping it elevated relative to the product punch 530. Conversely, the second lifting component 542 drives the second lifting seat 541 to fall, causing the second supporting wings 543 to fall and separate from the spring material seat 520, thereby removing the supporting force on the spring material seat 520. This allows the spring material seat 520 to fall and reset relative to the product punch 530 under the elastic force of the second elastic element 550.

[0049] Both sides of the spring material holder 520 are provided with outwardly protruding second outwardly protruding handles for support by the second supporting wing 543. The second lifting component 542 includes a second lifting cylinder, the cylinder body of which is fixed to the lifting seat 211, and the piston rod of which is fixedly connected to the second lifting seat 541 for easy connection. Of course, the second lifting component 542 can also be a linear motor or the like, as long as it can drive the second lifting seat 541 to rise and fall. However, using a second lifting cylinder for the second lifting component 542 is the optimal embodiment of the present invention, as it facilitates connection.

[0050] The second lifting seat 541 includes a second top seat located above the lifting seat 211. One side of the second top seat is provided with a second front movable rod that is movably inserted into the lifting seat 211, and the other side is provided with a second rear movable rod that is movably inserted into the lifting seat 211. One of the two second supporting wings 543 is fixedly connected to the second front movable rod, and the other is fixedly connected to the second rear movable rod. The piston rod of the second lifting cylinder is fixedly connected to the second top seat of the second lifting seat 541. By adopting the above structure, the second lifting seat 541 can stably lift the spring material seat 520 while reducing its weight and facilitating connection.

[0051] The frame 110 is also fixed with a silicone oil thinner spray head 810 that sprays towards the product punching station 140. The shift die double punch press also includes a silicone oil thinner supply device 820 for supplying silicone oil thinner to the silicone oil thinner spray head 810, so that the silicone oil thinner is sprayed through the silicone oil thinner spray head 810, which helps to make the punching edge smooth.

[0052] The translation drive device 222 is a translation drive cylinder. The piston rod of the translation drive cylinder is connected to the translation seat 221, so that the reciprocating motion of the piston rod can drive the reciprocating linear motion of the translation seat 221. The cylinder body of the translation drive cylinder is fixed on the frame 110. Of course, in addition to this, the translation drive device 222 can also be a lead screw, lead screw nut and motor, etc., as long as it can drive the translation seat 221 to make corresponding movements. However, using a translation drive cylinder as the translation drive device 222 is the optimal embodiment of the present invention, which can facilitate connection and provide more stable and higher pressure driving power.

[0053] The frame 110 is provided with guide rails, and the translation seat 221 is movably mounted on the guide rails to improve the smoothness of the movement of the translation seat 221. As a further preferred embodiment of the present invention, a displacement electronic ruler 230 for detecting the displacement of the translation seat 221 is fixed on the frame 110, so that the displacement of the translation seat 221 can be accurately obtained by means of the displacement electronic ruler 230.

[0054] The lifting drive device 212 is a lifting drive cylinder. The piston rod of the lifting drive cylinder is connected to the lifting seat 211, so that the lifting seat 211 can be lifted and lowered by the movement of the piston rod. The frame 110 has a cylinder mounting plate located above the burr punching station 130 and the product punching station 140, and the cylinder body of the lifting drive cylinder is fixed on the cylinder mounting plate. Of course, in addition to this, the lifting drive device 212 can also use a lead screw, lead screw nut and motor, etc., as long as it can lift and lower the lifting seat 211. However, using a lifting drive cylinder as the lifting drive device 212 is the optimal embodiment of the present invention, which can facilitate connection and provide more stable and higher pressure driving power.

[0055] The cylinder mounting plate is also connected to several downward-extending support columns. The lifting seat 211 is provided with several fittings that correspond one-to-one with the support columns and are slidably fitted onto the corresponding support columns, thereby improving the stability of the lifting seat 211's lifting. As a further preferred embodiment of the present invention, the frame 110 is fixed with a stamping stroke electronic ruler 240 for detecting the stamping stroke of the lifting seat 211, so that the stamping stroke of the lifting seat 211 can be accurately obtained through the stamping stroke electronic ruler 240.

[0056] The product punch 530 can be supplied with gas through an external gas distribution device. Gas is introduced into the positive pressure gas channel 531, while the vacuum adsorption seat 310 can be evacuated and supplied with gas through an external gas distribution device. A positive / negative pressure conversion mechanism 250 can be connected between the vacuum adsorption seat 310 and the external gas distribution device, so that the evacuation and gas supply states can be switched.

[0057] The frame 110 is also provided with a workpiece placement area. The loading station 120 is located between the workpiece placement area and the burr punching station 130. In use, the workpieces can be stacked on the workpiece placement area to facilitate the placement of the workpieces from the workpiece placement area onto the burr punching die 400 of the loading station 120 for loading.

[0058] Specifically, the frame 110 also includes a main frame, the cylinder mounting plate is located above the main frame, the lower ends of the support columns are all fixed on the main frame, the feeding station 120, the burr punching station 130, and the product punching station 140 are all located above the top surface of the main frame, and the burr guide groove 111 and the product guide groove 112 both penetrate the top surface of the main frame.
