Description

Technical Field

[0001] The invention relates to the technical field of cold stamping dies, in particular to a mesh plate processing die capable of reducing burrs. Background Art

[0002] Cold stamping dies are special process equipment used to process metal or non-metal materials into parts or semi-finished products in cold stamping. Stamping is a pressure processing method that uses dies installed on hydraulic presses or electric presses to apply pressure to materials at room temperature to separate or plastically deform them, thereby obtaining the required parts.

[0003] like Figure 5 As shown in the figure, due to the irregular distribution of the mesh holes of this product (no holes need to be punched at the four corners and some positions in the lower middle), it is impossible to punch out all the holes (11525 holes) on one set of molds using a traditional fixed punch mesh punching mold. Punching holes in batches must be done in multiple steps. In this way, several sets of molds must be processed to complete the processing of the product, which will consume a lot of manpower and material resources and have low production efficiency.

[0004] Therefore, a screen processing die capable of reducing burrs is proposed. Summary of the invention

[0005] An object of the present invention is to provide a screen processing die capable of reducing burrs, thereby solving or at least alleviating one or more of the above-mentioned problems and other problems existing in the prior art.

[0006] In order to achieve the above object, the main technical solutions adopted by the present invention include:

[0007] A screen processing die capable of reducing burrs comprises a lower support plate, a guide column is fixedly mounted on the top of the lower support plate, an upper support plate is fixedly mounted on the top of the guide column, a lower template for placing a plate body is fixedly mounted on the top of the lower support plate through a lining plate, a punch mechanism is movably arranged between the lining plate and the upper support plate, and a driving mechanism for driving the punch mechanism to move downward is arranged on the upper support plate;

[0008] The punch mechanism includes a punch mounting seat, on which a plurality of punch units are arranged, each of which includes a punch assembly and a locking assembly. The punch assembly is used to punch a plate body, and the locking assembly is used to control whether the punch assembly performs punching.

[0009] In a screen processing die capable of reducing burrs according to the present invention, the punch assembly comprises a punch and a limit slider, and the punch is fixedly connected to the bottom of the limit slider;

[0010] A limiting slide groove is provided on the top of the punch mounting seat, a vertical hole connected to the limiting slide groove is provided on the bottom of the punch mounting seat, the limiting slider is slidably arranged inside the limiting slide groove, and the lower end of the punch can extend from the vertical hole to the bottom of the punch mounting seat;

[0011] The locking assembly includes an electromagnet and a movable rod. A third assembly groove is provided on the side of the punch mounting seat. A first assembly groove connected to the limiting slide groove is provided inside the punch mounting seat. A second assembly groove is provided inside the punch mounting seat. Both ends of the second assembly groove are respectively connected to the third assembly groove and the first assembly groove. The electromagnet is fixedly mounted on one end of the third assembly groove away from the limiting slide groove. The movable rod is slidably inserted in the second assembly groove. One end of the movable rod slides into the first assembly groove and then is fixedly connected to the limiting plug block. The other end of the movable rod slides into the third assembly groove and then is fixedly connected to an iron block. After the electromagnet is energized, the iron block can be attracted by the magnetic force generated by the electromagnet and move in a direction away from the limiting slide block. A first spring is sleeved on the movable rod. One end of the first spring abuts against one end of the limiting plug block. The other end of the first spring abuts against one end of the first assembly groove away from the limiting slide block. A locking hole is provided on the side of the limiting slide block. The limiting plug block can be inserted into the locking hole under the elastic force of the first spring.

[0012] In a mesh processing mold that can reduce burrs according to the present invention, the driving mechanism includes a hydraulic cylinder, which is fixedly installed on the top of the upper support plate, and the bottom of the piston rod of the hydraulic cylinder slides through the bottom of the upper support plate and is fixedly installed with an inverted U-shaped frame, and connecting blocks are fixedly installed at both ends of the punch mounting seat, and the top of the connecting block is fixedly connected to the bottom of the inverted U-shaped frame.

[0013] In a screen processing mold capable of reducing burrs according to the present invention, a guide sliding hole is opened on the connecting block, a sliding sleeve is fixedly installed inside the guide sliding hole, and the sliding sleeve is slidably mounted on the guide column.

[0014] In a mesh processing mold that can reduce burrs according to the present invention, a reset assembly is installed on the punch mounting seat, and the reset assembly includes a vertical rod, a second spring and a baffle. The baffle is fixedly installed on the top of the punch mounting seat by screws, and the vertical rod is fixedly connected to the top of the limit slider. The upper end of the vertical rod slides through the top of the baffle. The second spring is sleeved on the vertical rod, and the bottom of the second spring is pressed on the top of the limit slider, and the top of the second spring is against the bottom of the baffle.

[0015] The present invention has at least the following beneficial effects:

[0016] The present invention can selectively lock the punch quickly by cooperating with the locking assembly through the punch assembly provided, and can drive the punch mounting plate to move downward through the provided hydraulic cylinder, thereby driving the punch to move downward to perform a punching operation on the plate body, and the locked punch participates in the punching operation, while the unlocked punch moves upward after contacting the plate body, retracts into the vertical hole, and does not participate in the punching operation;

[0017] The reset assembly can be set so that after a punching is completed and the punch mounting seat drives the punch to move up and reset, the limit slider can be accurately reset downward under the elastic force of the second spring, ensuring that the limit plug can be accurately inserted into the locking hole after the electromagnet is powered off;

[0018] By setting up the pre-pressing component, the plate body can be pressed before punching, which can avoid the plate body from moving during the punching process, thereby ensuring the quality of the punching. Through holes corresponding to the punches are opened on the pre-pressing plate, and punching holes corresponding to the punches are also opened on the lower template. Except for these punching areas, the rest are solid support areas. Therefore, when the punch punches the plate body, the non-punching area on the plate body can be effectively supported. In this way, when the plate body is punched, the plate body will not be deformed, thereby effectively reducing the generation of burrs and further improving the quality of the punching.

[0019] The anti-deviation mechanism can limit the position of plates of different sizes to avoid the deviation of the plates during feeding, thus further improving the punching accuracy of the plates.

[0020] The overall structure of the mold is simple, the volume is small, and the manufacturing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0047] Please refer to Figures 1 to 14 As shown, this embodiment provides a screen processing mold capable of reducing burrs, comprising a lower support plate 1, a guide column 101 is fixedly installed on the top of the lower support plate 1, an upper support plate 102 is fixedly installed on the top of the guide column 101, a lower template 103 for placing a plate body 6 is fixedly installed on the top of the lower support plate 1 through a lining plate 104, a punch mechanism 2 is movably arranged between the lining plate 104 and the upper support plate 102, and a driving mechanism 3 for driving the punch mechanism 2 to move downward is arranged on the upper support plate 102;

[0048] The punch mechanism 2 includes a punch mounting seat 201, on which multiple groups of punch units are arranged. The multiple groups of punch units each include a punch assembly 202 and a locking assembly 203. The punch assembly 202 is used to punch the plate body 6, and the locking assembly 203 is used to control whether the punch assembly 202 punches.

[0049] In this embodiment, the punch assembly 202 includes a punch 2021 and a limit slider 2022, and the punch 2021 is fixedly connected to the bottom of the limit slider 2022;

[0050] A limit slot 2011 is provided at the top of the punch mounting seat 201, a vertical hole 2012 connected to the limit slot 2011 is provided at the bottom of the punch mounting seat 201, a limit slider 2022 is slidably arranged inside the limit slot 2011, and the lower end of the punch 2021 can extend from the vertical hole 2012 to the bottom of the punch mounting seat 201;

[0051] The locking assembly 203 includes an electromagnet 2031 and a movable rod 2032. A third assembly groove 2015 is provided on the side of the punch mounting seat 201. A first assembly groove 2013 connected to the limiting slide groove 2011 is provided inside the punch mounting seat 201. A second assembly groove 2014 is provided inside the punch mounting seat 201. The two ends of the second assembly groove 2014 are respectively connected to the third assembly groove 2015 and the first assembly groove 2013. The electromagnet 2031 is fixedly installed at one end of the third assembly groove 2015 away from the limiting slide groove 2011. The movable rod 2032 is slidably inserted into the second assembly groove 2014. One end of the movable rod 2032 slides into the first assembly groove 2013 and is fixedly connected to the limiting slide groove 2011. The movable rod 2032 is provided with a first spring 2035, one end of the first spring 2035 abuts against one end of the limiting plug 2034, and the other end of the first spring 2035 abuts against one end of the first assembly groove 2013 away from the limiting slider 2022. A locking hole 20221 is provided on the side of the limiting slider 2022, and the limiting plug 2034 can be inserted into the locking hole 20221 under the elastic force of the first spring 2035.

[0052] By adopting the above technical solution, when in use, when the electromagnet 2031 corresponding to the punch 2021 is not energized, the limit plug 2034 is inserted into the locking hole 20221 under the elastic force of the first spring 2035, and the limit slider 2022 is fixed in the limit slide groove 2011. When the punch mounting seat 201 drives the punch 2021 to move downward to punch the plate body 6, the punch 2021 participates in the punching operation. When the electromagnet 2031 corresponding to the punch 2021 is energized, the magnetic force generated by the electromagnet 2031 attracts the iron block 2033 to move in the direction away from the limit slider 2022, so that the iron block 2033 drives the limit plug 2034 through the movable rod 2032. 34 is pulled out from the locking hole 20221, so that the limit plug 2034 releases the lock of the limit slider 2022. When the punch mounting seat 201 drives the punch 2021 to move downward to punch the plate body 6, the punch 2021 will be pushed into the vertical hole 2012 when it contacts the plate body 6, so that the punch 2021 does not participate in the punching operation. That is to say, before punching, some electromagnets 2031 are controlled to be energized, so that the punch 2021 corresponding to the electromagnet 2031 can be controlled not to participate in the punching operation, while other punches 2021 participate in the punching operation. In this way, which punches 2021 are used for punching and which punches 2021 are not used can be set according to the punching needs.

[0053] In this embodiment, the driving mechanism 3 includes a hydraulic cylinder 301, which is fixedly installed on the top of the upper support plate 102. The bottom of the piston rod of the hydraulic cylinder 301 slides through the bottom of the upper support plate 102 and is fixedly installed with an inverted U-shaped frame 302. Both ends of the punch mounting seat 201 are fixedly installed with connecting blocks 303, and the top of the connecting block 303 is fixedly connected to the bottom of the inverted U-shaped frame 302.

[0054] By setting up the driving mechanism 3, when in use, the piston rod of the hydraulic cylinder 301 is controlled to extend, and the punch 2021 can be driven to move downward through the punch mounting seat 201 to perform the punching operation, and the piston rod of the hydraulic cylinder 301 is controlled to retract, thereby driving the punch 2021 to move upward for resetting.

[0055] In this embodiment, in order to ensure that the punch mounting seat 201 can move up and down stably to improve the punching quality, a guide slide hole 3031 is opened on the connecting block 303, and a sliding sleeve is fixedly installed inside the guide slide hole 3031, and the sliding sleeve is arranged on the guide column 101.

[0056] In this embodiment, a reset assembly 204 is installed on the punch mounting seat 201, and the reset assembly 204 includes a vertical rod 2041, a second spring 2042 and a baffle 2043. The baffle 2043 is fixedly installed on the top of the punch mounting seat 201 by screws. The vertical rod 2041 is fixedly connected to the top of the limiting slider 2022. The upper end of the vertical rod 2041 slides through the top setting of the baffle 2043. The second spring 2042 is sleeved on the vertical rod 2041. The bottom of the second spring 2042 is pressed on the top of the limiting slider 2022, and the top of the second spring 2042 is against the bottom of the baffle 2043.

[0057] By setting the reset component 204, after a punching is completed and the punch mounting seat 201 drives the punch 2021 to move up and reset, the limit slider 2022 can be accurately reset downward under the elastic force of the second spring 2042, ensuring that after the electromagnet 2031 is powered off, the limit plug 2034 can be accurately inserted into the locking hole 20221.

[0058] In this embodiment, a pre-stressing assembly 4 is arranged below the punch mounting seat 201, and the pre-stressing assembly 4 includes a pre-stressing plate 401, and a through hole 4011 corresponding to the punch 2021 is opened on the pre-stressing plate 401, and both ends of the pre-stressing plate 401 are fixedly connected with a sliding rod 402, and the upper end of the sliding rod 402 slides through the connecting block 303, and the top of the sliding rod 402 is fixedly connected to the limiting block 404, and a third spring 403 is sleeved on the sliding rod 402, and the bottom of the third spring 403 is pressed on the top of the pre-stressing plate 401, and the top of the third spring 403 is against the bottom of the connecting block 303, and the lower template 103 is provided with a punching hole 1031 corresponding to the punch 2021, and the lower end of the punch 2021 can pass through the through hole 4011 to punch the plate body 6.

[0059] By adopting the above arrangement, when the punch mounting seat 201 moves downward, it will drive the pre-pressing plate 401 to move downward. When the pre-pressing plate 401 is pressed onto the plate body 6, the plate body 6 will be initially squeezed to position the plate body 6. As the punch mounting seat 201 continues to move downward, the third spring 403 is continuously compressed, so that the plate body 6 is pressed tightly by the pre-pressing plate 401, and then the lower end of the punch 2021 passes through the through hole 4011 to punch the plate body 6. When the punching is completed, the punch mounting seat 201 drives the punch 2021 to move upward. At this time, the pre-pressing plate 401 will also squeeze the plate body 6 under the elastic force of the third spring 403, so that the punch 2021 can be smoothly pulled out from the plate body 6 to prevent the plate body 6 from being stuck on the punch 2021, and a through hole 4011 corresponding to the punch 2021 is opened on the pre-pressing plate 401, and a punching hole 1031 corresponding to the punch 2021 is also opened on the lower template 103. Except for these punching areas, the rest are solid support areas. Therefore, when the punch 2021 punches the plate body 6, the non-punching area on the plate body 6 can be effectively supported. In this way, when the plate body 6 is punched, the plate body 6 will not be deformed, thereby effectively reducing the generation of burrs and further improving the quality of punching.

[0060] In this embodiment, a collection port 1001 is provided at the top of the lower support plate 1, a discharge port 1003 is provided at the side of the lower support plate 1, and a material guide slope 1002 in an inverted V shape is provided at the bottom of the material guide slope 1002. After the punching waste falls into the collection port 1001, it is discharged from the discharge port 1003 via the material guide slope 1002. This arrangement facilitates the discharge of waste generated by punching.

[0061] In this embodiment, an anti-deviation mechanism 5 is provided on the lower support plate 1. The anti-deviation mechanism 5 is used to prevent the plate body 6 from deflecting when punching and feeding. The anti-deviation mechanism 5 includes two screw rods 501, and the two screw rods 501 are respectively arranged on both sides of the lower template 103. The screw rods 501 are rotatably mounted on the lower support plate 1 through the vertical block 502. The threads at both ends of the screw rod 501 are arranged in opposite directions. Both ends of the screw rod 501 are threadedly rotatably connected with nuts 505. The top of the nut 505 is rotatably mounted with a guide roller 506. The two screw rods 50 1 are connected by a transmission member, wherein the transmission member includes a synchronous wheel 507 fixed to one end of the screw rod 501, and the synchronous wheels 507 on the two screw rods 501 are connected by a synchronous belt 508, and one end of one of the screw rods 501 is fixedly connected to a hand wheel 509. In order to ensure that the nut 505 can drive the guide roller 506 to move smoothly, the top of the lower support plate 1 is fixedly connected to a slide rail 503, and the bottom of the nut 505 is fixedly connected to a sliding block 504, and the sliding block 504 is slidably installed on the slide rail 503.

[0062] By adopting the above-mentioned arrangement, the plate body 6 is placed on the lower template 103, and then the hand wheel 509 is rotated, thereby driving the screw rod 501 to rotate, so that the guide rollers 506 at both ends of the screw rod 501 move toward each other, and the two sides of the plate body 6 are positioned, so that the plate body 6 can be guided by the guide rollers 506 during punching and feeding, thereby avoiding the plate body 6 from being offset.

[0063] The above description shows and describes several preferred embodiments of the present invention, but as mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the invention concept described herein through the above teachings or the technology or knowledge of the relevant field.
