Description

Technical Field

[0001] The present invention relates to the technical field of sheet metal stamping equipment, and in particular to a sheet metal stamping equipment with a trimming function and a use method thereof. Background Art

[0002] Stamping equipment is a kind of equipment that uses punching force and stamping die to punch metal parts into corresponding shapes or achieve related shearing effects. For example, punching operations are completed using stamping equipment. Generally, trimming is required after punching is completed. Because burrs will appear on the upper and lower edges of the hole during the punching process, the inner wall of the hole is a shear fracture surface and will not produce typical burrs, so the upper and lower edges need to be trimmed.

[0003] After the existing stamping equipment performs the punching operation, the punching die cooperates to punch out holes at the corresponding positions on the sheet metal, and then the upper and lower edges of the hole positions are trimmed. For example, the Chinese patent with the authorization announcement number CN119187353B discloses a hydraulically controlled stamping device for a radial diffuser assembly, including a hydraulic control unit, on which a punching auxiliary part is installed; the punching auxiliary part is used for punching; the punching auxiliary part is installed with a stamping trimming part; after the punching is completed, the stamping trimming part is used to perform trimming.

[0004] The disadvantage of the existing stamping equipment with trimming function is that when the existing stamping equipment performs a punching operation, the workpiece is trimmed after the hole is punched, and then the workpiece is removed and the next workpiece to be punched is loaded onto the mold. For example, the solution disclosed in the Chinese patent with authorization announcement number CN119187353B is to continue the operation after completing the punching, complete the trimming, and then remove it from the mold. There is also a method of first removing the punched workpiece from the mold, then transferring it to the trimming equipment, and then trimming it. That is, the trimming and unloading processes need to be performed separately, that is, the existing stamping equipment with trimming function cannot perform trimming and unloading at the same time, which results in the trimming taking a certain amount of time separately, reducing processing efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a sheet metal stamping equipment with a trimming function and a method of use, so as to solve the technical problem that the stamping equipment with a trimming function in the prior art needs to perform trimming, unloading and other processes separately, thereby reducing the processing efficiency.

[0010] Preferably, the trimming cutter group includes a drive motor, an upper trimming cutter head, a lower trimming cutter head and a transverse telescopic connecting piece. The drive motor is fixedly connected to the lifting end of the automatic lifting drive mechanism, and the upper trimming cutter head is horizontally fixedly connected to the main shaft end of the drive motor; the lower trimming cutter head is connected to the bottom of the upper trimming cutter head through a transverse telescopic connecting piece.

[0011] Preferably, the transverse telescopic connecting member includes a connecting guide sleeve, a linkage rod and a linkage base plate, the connecting guide sleeve is fixedly arranged below the upper trimming head, two lower trimming heads are provided, and they are symmetrically slid laterally and inserted into the two ends of the connecting guide sleeve, the linkage base plate is provided below the connecting guide sleeve, two linkage rods are provided, and one end of each linkage rod is movably connected to the linkage base plate by a hinge, and the other end is movably connected to the corresponding lower trimming head by a hinge; the blanking recovery mechanism includes a material receiving guide frame fixedly arranged laterally on the side of the punching die mechanism away from the raw material conveying mechanism, and the extrusion cross plate is horizontally fixedly connected to the inside of the material receiving guide frame.

[0012] Preferably, a universal ball assembly is installed at the bottom of the linkage base plate.

[0013] Preferably, the material blanking and recovery mechanism also includes a blanking port, which is opened at the bottom of one end of the material receiving guide frame away from the punching die mechanism, an inclined guide plate is fixedly connected below the blanking port, and a material receiving box is provided at the end of the inclined guide plate.

[0014] Preferably, a plurality of support rollers are laterally and evenly distributed on the inner walls of both sides of the material receiving guide frame, and each support roller is rotatably connected to the material receiving guide frame.

[0015] Preferably, the raw material conveying mechanism includes a step-by-step conveyor belt assembly and a conveying guide plate. The step-by-step conveyor belt assembly is installed on one side of the punching die mechanism. There are two conveying guide plates, which are arranged parallel to both sides of the conveying surface of the step-by-step conveyor belt assembly.

[0016] Preferably, the material picking mechanism includes an electric guide rail, an electric telescopic rod and a vacuum suction cup mechanism; the electric guide rail is horizontally arranged above the stepping conveyor belt assembly and extends to the inside of the material receiving guide frame, the electric guide rail is slidably connected to a slide, the electric telescopic rod is fixedly connected to the slide, the telescopic end of the electric telescopic rod is fixedly connected to a connecting cross plate, the vacuum suction cup mechanism is provided with two groups, which are respectively installed at both ends of the connecting cross plate, and the lifting guide rod vertically passes through one end of the connecting cross plate close to the punching die mechanism.

[0017] A method for using sheet metal stamping equipment with a trimming function, the specific steps are as follows:

[0018] The first step is to place the sheet metal parts to be punched onto the raw material conveying mechanism for transportation;

[0019] The second step is to take the sheet metal original to be punched from the raw material conveying mechanism through the material taking mechanism and put it onto the punching die mechanism;

[0020] The third step is that the punching die mechanism punches the placed sheet metal parts;

[0021] The fourth step is to take the sheet metal original to be punched from the raw material conveying mechanism again through the material taking mechanism, and at the same time transfer the punched sheet metal original to the lower material recovery mechanism. During the transfer of the punched sheet metal original to the lower material recovery mechanism, the trimming mechanism trims the edges of the holes on the punched sheet metal original.

[0022] Beneficial effects of the present invention:

[0023] 1. When the present invention removes the punched sheet metal original from the punching die mechanism through the material taking mechanism and conveys it to the lower material recovery mechanism, the provided extrusion bevel and the extrusion cross plate in the receiving guide frame are squeezed, thereby causing the lifting guide rod connected to the extrusion bevel to descend, and the lifting guide rod drives the provided upper trimming head to descend and contact the upper edge of the punching position. At the same time, the lower trimming head is squeezed to the bottom of the receiving guide frame through the linkage bottom plate connected to the linkage rod. The linkage rod is deflected to push the lower trimming head out and contact the lower edge of the punching position, thereby facilitating the trimming of the punching position during the unloading process and improving the processing efficiency.

[0024] 2. A blanking port is provided at the bottom of one end of the receiving guide frame of the present invention. When the linkage bottom plate squeezed on the inner bottom surface of the receiving guide frame moves to the position of the blanking port, it becomes suspended. At this time, the linkage bottom plate falls, making it easy for the lower trimming cutter head to be stored in the connecting guide sleeve, thereby avoiding obstruction under the sheet metal original and facilitating the release and removal of the punched sheet metal original.

[0025] 3. When the material picking mechanism of the present invention absorbs the punched sheet metal original through a group of vacuum suction cup mechanisms, the other group of vacuum suction cup mechanisms is just aligned with the sheet metal original to be punched on the raw material conveying mechanism, so as to facilitate the simultaneous grabbing of the punched sheet metal original and the sheet metal original to be punched. Then, when the material picking mechanism drives the punched sheet metal original to move horizontally into the receiving guide frame for unloading, the sheet metal original to be punched is just moved to the punching die mechanism, realizing the synchronous operation of unloading and loading, thereby improving production efficiency.

DETAILED DESCRIPTION

[0039] The specific embodiments of the present invention are described in detail below, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0040] like Figures 1-11As shown, a sheet metal stamping equipment with a trimming function is used to punch a sheet metal original 600. The stamping equipment includes a punching die mechanism 100, a raw material conveying mechanism 200, a material taking mechanism 300 and a blanking and recycling mechanism 400. The punching die mechanism 100 is used to punch the placed sheet metal original 600. The raw material conveying mechanism 200 is arranged on one side of the punching die mechanism 100. The raw material conveying mechanism 200 is used to convey the sheet metal original 600 to be punched; the blanking and recycling mechanism 400 is arranged on the other side of the punching die mechanism 100. The material taking mechanism 300 is used to drive the punched sheet metal original 600 to be transferred horizontally to the blanking and recycling mechanism 400; in this way, the punched sheet metal original 600 can be collected into the blanking and recycling mechanism 400, and the sheet metal original 600 to be punched is placed on the punching die mechanism 100; the stamping equipment also includes a trimming mechanism 500, which is cooperatively arranged on the material picking mechanism 300, and the trimming mechanism 500 includes an automatic lifting drive mechanism and a trimming rotary cutter group. When the material picking mechanism 300 transfers the punched sheet metal original 600 to the down material recovery mechanism 400, the automatic lifting drive mechanism drives the trimming rotary cutter group to descend and dock with the punching position of the punched sheet metal original 600 for rotational grinding; in this way, trimming can be completed during the down material feeding process without the need for separate trimming operations, thereby improving work efficiency. At the same time, it can also avoid trimming directly on the punching die mechanism 100, causing metal debris to fall onto the die, affecting subsequent processing operations.

[0041] In some specific embodiments, such as Figure 5 As shown, the automatic lifting drive mechanism includes a lifting guide rod 502, an extrusion bevel block 503 and an extrusion cross plate 509. The lifting guide rod 502 is longitudinally slidably arranged on the material picking mechanism 300, and a compressible support spring is also arranged between the lifting guide rod 502 and the material picking mechanism 300. The extrusion bevel block 503 is fixedly connected to the top of the lifting guide rod 502, the extrusion cross plate 509 is horizontally arranged in the unloading and recovery mechanism 400, and the extrusion cross plate 509 is matched with the inclined surface of the extrusion bevel block 503, and the trimming rotary knife group is arranged at the bottom of the lifting guide rod 502.

[0042] In some specific embodiments, such as Figure 5As shown, the trimming rotary cutter group includes a driving motor 501, an upper trimming cutter head 504, a lower trimming cutter head 505 and a horizontal telescopic connecting piece. The driving motor 501 is fixedly connected to the lifting end of the automatic lifting driving mechanism through a mounting seat. Specifically, the driving motor 501 can be fixedly connected to the bottom of the lifting guide rod 502 of the automatic lifting driving mechanism through the mounting seat. The main shaft end of the driving motor 501 is vertically downward, and the main shaft end of the driving motor 501 is fixedly connected to the cutter seat. The upper trimming cutter head 504 is horizontally fixedly connected to the main shaft end of the driving motor 501 through the cutter seat, and the upper trimming cutter head 504 is horizontally fixedly connected to the main shaft end of the driving motor 501 through the cutter seat. Two trimming heads 504 can be provided, symmetrically distributed on both sides of the tool holder, and the end of the upper trimming head 504 is a downward inclined structure for fitting the upper edge of the hole of the punched sheet metal original 600; the lower trimming head 505 is connected to the bottom of the upper trimming head 504 through a transverse telescopic connecting piece, and the lower trimming head 505 performs telescopic movement through the transverse telescopic connecting piece, so as to facilitate descending through the hole, and then stretching laterally to facilitate contact with the lower edge of the hole, and the end of the lower trimming head 505 is an upward inclined structure for fitting the lower edge of the hole of the punched sheet metal original 600.

[0043] Among them, reference Figure 10 and Figure 11 As shown, the transverse telescopic connecting member includes a connecting guide sleeve 506, a linkage rod 508 and a linkage base plate 507. The connecting guide sleeve 506 is fixedly arranged below the upper trimming cutter head 504, and can be fixedly connected to the knife seat connected to the upper trimming cutter head 504 through a bracket. There are two lower trimming cutter heads 505, which are symmetrically slidably inserted into the two ends of the connecting guide sleeve 506. The connecting guide sleeve 506 and the lower trimming cutter head 505 are both square structures to prevent relative rotation between the two. The linkage base plate 507 is arranged below the connecting guide sleeve 506, and two linkage rods 508 are provided. They are tilted between the corresponding lower trimming cutter head 505 and the linkage base plate 507, and one end is movably connected to the linkage base plate 507 by a hinge, and the other end is connected to the corresponding The lower trimming head 505 is movably connected by a hinge, and a compressible limit spring can be installed between the linkage base plate 507 and the outer wall of the connecting guide sleeve 506. The lower trimming head 505 is initially stored in the connecting guide sleeve 506, and the distance between the ends of the lower trimming head 505 in the stored state at both ends of the connecting guide sleeve 506 is smaller than the aperture of the punching hole; the blanking recovery mechanism 400 includes a material receiving guide frame 401 fixedly arranged horizontally on the side of the punching die mechanism 100 away from the raw material conveying mechanism 200, and the extrusion cross plate 509 is horizontally fixedly connected to the inside of the material receiving guide frame 401 through a bracket. Here, the bracket connected to the extrusion cross plate 509 is used to avoid interfering with the material taking mechanism 300 to drive the punched sheet metal original 600 to move horizontally into the material receiving guide frame 401.

[0044] When the picking mechanism 300 grabs the punched sheet metal original 600 and moves horizontally into the receiving guide frame 401, the downward inclined surface structure of the upper trimming head 504 of the trimming rotary cutter group is aligned with the upper edge of the hole of the punched sheet metal original 600, and the lower trimming head 505 in the storage state is in the hole. At this time, the bottom of the inclined surface of the extrusion inclined block 503 is aligned with the extrusion cross plate 509, and the linkage bottom plate 507 is close to the inner bottom surface of the receiving guide frame 401. During the transverse driving process of the picking mechanism 300, the bottom of the inclined surface of the extrusion inclined block 503 and the extrusion cross plate 509 produce an extrusion effect, and the inclined surface is subjected to a downward component of force, thereby driving the lifting guide rod 502 to descend, and the lifting guide rod 502 drives the upper trimming head 505 at the spindle end. 04 and the lower trimming cutter head 505 descend. During the descent process, the linkage bottom plate 507 is squeezed onto the receiving guide frame 401, and the distance between the linkage bottom plate 507 and the connecting guide sleeve 506 gradually decreases. During this process, the linkage bottom plate 507 pushes the lower trimming cutter head 505 to slide horizontally relative to the connecting guide sleeve 506 through the linkage rod 508. That is, the lower trimming cutter head 505 also moves horizontally in the process of synchronously descending with the lifting guide rod 502. Finally, the lower trimming cutter head 505 just descends to a position aligned with the lower edge of the punching hole, and the upward inclined surface structure at its end just moves horizontally to contact the lower edge of the hole, and the downward inclined surface structure at the end of the upper trimming cutter head 504 just descends to contact the upper edge of the hole.

[0045] It should be noted that a pressure sensing switch electrically connected to the drive motor 501 can be provided at the bottom of the connecting guide sleeve 506, which is not shown in the figure. When the linkage base plate 507 is squeezed close to the connecting guide sleeve 506, the linkage base plate 507 can eventually act on the pressure sensing switch, thereby causing the drive motor 501 to operate, so that the upper trimming head 504 and the lower trimming head 505 rotate, making it convenient to grind and trim the upper and lower edges of the holes punched out on the sheet metal original 600.

[0046] It should also be noted that a negative pressure dust suction mechanism can be installed on the material receiving guide frame 401, and the negative pressure end of the negative pressure dust suction mechanism is connected to the interior of the material receiving guide frame 401 through a pipe, which is convenient for sucking the internal air and sucking away the dust generated during the trimming process.

[0047] In some specific embodiments, reference Figure 6 As shown, the blanking and recycling mechanism 400 also includes a blanking port 404, which is opened at the bottom of one end of the material receiving guide frame 401 away from the punching die mechanism 100. The size of the blanking port 404 is larger than the size of the sheet metal original 600. An inclined guide plate 405 is fixedly connected below the blanking port 404, and a material receiving box 402 is placed at the end of the inclined guide plate 405.

[0048] When the picking mechanism 300 drives the punched sheet metal original 600 to move to the position of the blanking port 404, the linkage bottom plate 507 is suspended in the air, so it drops and resets, thereby driving the lower trimming heads 505 on both sides to be stored in the connecting guide sleeve 506, so that the sheet metal original 600 can fall and slide along the inclined guide plate 405 into the receiving box 402, realizing the completion of trimming during the blanking and recycling process.

[0049] It should be noted that a gap can be reserved between the lower trimming heads 505 at both ends of the connecting guide sleeve 506, and a stretchable spring can be connected between the two lower trimming heads 505, so that the lower trimming heads 505 that slide out can be stored with the help of the rebound force.

[0050] In other specific embodiments, in order to facilitate the linkage base plate 507 to press against the inner bottom surface of the material receiving guide frame 401 and move laterally, a universal ball assembly is installed at the bottom of the linkage base plate 507, and the universal ball assembly includes a ball shell fixedly connected to the bottom of the linkage base plate 507 and a movable ball movably connected to the ball shell.

[0051] In some specific embodiments, in order to prevent the sheet metal original 600 from falling off during the trimming process, multiple support rollers 403 are distributed horizontally and equidistantly on the inner walls of both sides of the receiving guide frame 401, and each support roller 403 is rotatably connected to the receiving guide frame 401. When the material picking mechanism 300 grabs the punched sheet metal original 600, the bottom surface of the sheet metal original 600 is flush with the upper surface of the distributed support rollers 403, so that it can slide along the distributed support rollers 403 during the lateral movement. It should be noted that there are no support rollers 403 distributed above the position of the blanking port 404.

[0052] In some specific embodiments, the raw material conveying mechanism 200 includes a stepping conveyor belt assembly 201 and a conveying guide plate 202. The stepping conveyor belt assembly 201 is installed on one side of the punching die mechanism 100. The stepping conveyor belt assembly 201 includes two sets of driving wheels, a conveyor belt body wrapped around the two sets of driving wheels, and a stepping motor that drives one of the driving wheels to run; there are two conveying guide plates 202, which are arranged parallel to both sides of the conveying surface of the stepping conveyor belt assembly 201. The conveying guide plates 202 do not move with the stepping conveyor belt assembly 201. The conveying guide plates 202 are used to guide the sheet metal originals 600 to be punched to avoid deviation from the position. The stepping conveyor belt assembly 201 is used to convey the sheet metal originals 600 to be punched one by one.

[0053] In some embodiments, combined Figure 3 and Figure 4As shown, the material picking mechanism 300 includes an electric guide rail 302, an electric telescopic rod 303 and a vacuum suction cup mechanism 305; the electric guide rail 302 is horizontally arranged above the stepping conveyor belt assembly 201 and extends to the inside of the material receiving guide frame 401, and the electric guide rail 302 is slidably connected to the slide 301, the electric telescopic rod 303 is fixedly connected to the slide 301, and the telescopic end is vertically downward, and the telescopic end of the electric telescopic rod 303 is fixedly connected to the connecting cross plate 304, and the vacuum suction cup mechanism 305 is provided with two groups, which are respectively installed at both ends of the connecting cross plate 304, and the vacuum suction cup mechanism 305 includes a downward suction cup body and a negative pressure pump for generating a negative pressure effect on the suction cup body; the lifting guide rod 502 vertically passes through one end of the connecting cross plate 304 close to the punching die mechanism 100, and the lifting guide rod 502 can be a square rod to avoid rotation.

[0054] After the sheet metal original 600 placed on the punching die mechanism 100 is punched, the slide 301 is controlled to move horizontally along the electric guide rail 302, so that the corresponding vacuum suction cup mechanism 305 is aligned above the punched sheet metal original 600, and the other set of vacuum suction cup mechanisms 305 is just above the sheet metal original 600 to be punched on the stepping conveyor assembly 201. Here, a limit switch can be set at the corresponding position of the punching die mechanism 100, or the start and stop positions of the slide 301 running path can be set in advance through the program. When the slide 301 moves to the corresponding position and stops, the electric telescopic rod 303 is started to extend, and the electric telescopic rod 303 drives the vacuum suction cup mechanisms 3 at both ends through the connecting cross plate 304. 05 descends, and the two sets of vacuum suction cup mechanisms 305 are respectively pressed onto the corresponding sheet metal originals 600 and adsorbed, and then the electric telescopic rod 303 is controlled to shrink, so that the sheet metal original 600 to be punched and the punched sheet metal original 600 are raised at the same time, and then the slide 301 continues to advance along the electric guide rail 302, thereby driving the punched sheet metal original 600 to move horizontally into the receiving guide frame 401, and the sheet metal original 600 to be punched moves to the top of the punching die mechanism 100, and then the electric telescopic rod 303 is controlled to extend, driving the sheet metal original 600 to be punched to descend and be placed on the punching die mechanism 100, and the punched sheet metal original 600 falls to the blanking port 404 at this time to achieve recycling.

[0055] In some specific embodiments, reference Figure 1 and Figure 2As shown, the punching die mechanism 100 includes a support base 102, a fixed lower die 103, a punching upper die head 105 and a hydraulic telescopic rod 101. The support base 102 is arranged between the raw material conveying mechanism 200 and the blanking recovery mechanism 400. The fixed lower die 103 is fixedly installed on the support base 102. The fixed lower die 103 matches the sheet metal original 600 to be punched. A through hole for punching is opened on the fixed lower die 103, and a waste material passage connected to the through hole is opened on the support base 102. The hydraulic telescopic rod 101 is fixedly connected to the support base 102 through a bracket. On the support base 102, the telescopic end of the hydraulic telescopic rod 101 faces downward, the punching upper die head 105 is fixedly connected to the telescopic end of the hydraulic telescopic rod 101, and the punching upper die head 105 is aligned with the through hole on the fixed lower die 103, and a pressing plate 104 is provided below the punching upper die head 105. The pressing plate 104 has a hole in the middle, and guide columns 106 are fixedly connected on both sides of the pressing plate 104. The punching upper die head 105 is fixedly connected to a cross frame 108 near the upper side, and the guide columns 106 pass through the cross frame 108, and a connecting spring 107 is connected between the cross frame 108 and the pressing plate 104. When punching, the sheet metal original 600 is placed on the fixed lower mold 103, and then the hydraulic telescopic rod 101 drives the pressing plate 104 and the punching upper die head 105 to descend at the same time. The pressing plate 104 is first pressed onto the sheet metal original 600, and then the hydraulic telescopic rod 101 continues to drive the punching upper die head 105 to descend, pass through the pressing plate 104, and complete the punching on the sheet metal original 600.

[0056] It should be noted that when the electric guide rail 302 passes through the punching die mechanism 100, it is staggered with the pressure plate 104 and the hydraulic telescopic rod 101 to avoid motion interference. It should also be noted that when performing the punching operation, the slide 301 carries the vacuum suction cup mechanism 305 and the trimming mechanism 500 and moves horizontally from under the punching upper die head 105 to above the stepping conveyor belt assembly 201.

[0057] The specific steps for using the above sheet metal stamping equipment are as follows:

[0058] The first step is to place the sheet metal parts 600 to be punched onto the material conveying mechanism 200 for conveying.

[0059] Step 2: The sheet metal original 600 to be punched is taken from the raw material conveying mechanism 200 by the material taking mechanism 300 and is placed on the punching die mechanism 100;

[0060] Step 3: The punching die mechanism 100 punches the placed sheet metal component 600;

[0061] In the fourth step, the sheet metal original 600 to be punched is taken from the raw material conveying mechanism 200 again through the material taking mechanism 300, and the punched sheet metal original 600 is transferred to the lower material recovery mechanism 400. During the transfer of the punched sheet metal original 600 to the lower material recovery mechanism 400, the trimming mechanism 500 trims the edges of the holes on the punched sheet metal original 600.

[0062] To facilitate understanding of the embodiments of this solution by those skilled in the art, the working principle of this solution is briefly described in conjunction with specific application scenarios:

[0063] After the sheet metal original 600 placed on the punching die mechanism 100 is punched, the punching upper die head 105 is raised, and then the slide 301 is controlled to move laterally along the electric guide rail 302, so that the corresponding vacuum suction cup mechanism 305 is aligned above the punched sheet metal original 600, and the other set of vacuum suction cup mechanisms 305 is just above the sheet metal original 600 to be punched on the stepping conveyor assembly 201;

[0064] Then the electric telescopic rod 303 is started to extend, and the electric telescopic rod 303 drives the vacuum suction cup mechanisms 305 at both ends to descend through the connecting cross plate 304. The two sets of vacuum suction cup mechanisms 305 are respectively pressed onto the corresponding sheet metal originals 600 and adsorb them. Then the electric telescopic rod 303 is controlled to retract, so that the sheet metal original 600 to be punched and the punched sheet metal original 600 are lifted at the same time. Then the slide 301 continues to move along the electric guide rail 302, thereby driving the punched sheet metal original 600 to move horizontally into the receiving guide frame 401, and the sheet metal original 600 to be punched moves to the top of the punching die mechanism 100.

[0065] When the punched sheet metal original 600 moves horizontally into the receiving guide frame 401, the downward inclined surface structure of the upper trimming head 504 of the trimming rotary cutter group is aligned with the upper edge of the hole of the punched sheet metal original 600, and the lower trimming head 505 in the stored state is in the hole, and at this time, the inclined bottom of the extrusion inclined block 503 is aligned with the extrusion cross plate 509, and the linkage bottom plate 507 is close to the inner bottom surface of the receiving guide frame 401. During the horizontal movement and driving process of the material picking mechanism 300, the inclined bottom of the extrusion inclined block 503 and the extrusion cross plate 509 produce an extrusion effect, and the inclined surface is subjected to the downward component of the force, thereby driving the lifting guide rod 502 to descend, and the lifting guide rod 502 drives the upper trimming head 504 and the lower trimming head 505 on the spindle end to descend. During the descending process, the linkage bottom plate 507 is squeezed to the receiving guide frame. 401, and the distance between the linkage base plate 507 and the connecting guide sleeve 506 gradually decreases. During this process, the linkage base plate 507 pushes the lower trimming head 505 to slide and be pulled out relative to the connecting guide sleeve 506 laterally through the linkage rod 508, that is, the lower trimming head 505 also moves laterally synchronously during the process of synchronously descending with the lifting guide rod 502. Finally, the lower trimming head 505 just drops to a position aligned with the lower edge of the punched hole, and the upward inclined structure at its end just moves laterally to contact the lower edge of the hole, and the downward inclined structure at the end of the upper trimming head 504 just drops to contact the upper edge of the hole, and the driving motor 501 runs, so that the upper trimming head 504 and the lower trimming head 505 rotate, which is convenient for grinding and trimming the upper and lower edges of the holes punched on the sheet metal original 600.

[0066] When the punched sheet metal original 600 moves to the position of the blanking port 404 along with the slide 301, the linkage bottom plate 507 is suspended in the air, so it drops and resets, thereby driving the lower trimming heads 505 on both sides to be stored in the connecting guide sleeve 506, and then the electric telescopic rod 303 is controlled to extend, driving the sheet metal original 600 to be punched to drop onto the punching die mechanism 100, and the punched sheet metal original 600 now passes through the blanking port 404, and then the two sets of vacuum suction cup mechanisms 305 are stopped, releasing the sheet metal original 600 to be punched and the punched sheet metal original 600, and the punched sheet metal original 600 slides along the inclined guide plate 405 into the material receiving box 402, realizing trimming during the blanking and recycling process.

[0067] The above disclosures are only a few specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
