Description

Technical Field

[0001] The present invention relates to the technical field of static piece processing, in particular to a static piece forming device and a process thereof. Background Art

[0002] A switch stator, often referred to as a stator, is a stationary contact point in a switchgear. When the switch is closed, it contacts the moving plate (also known as the movable contact), forming a conductive path. When the switch is open, the stator separates from the moving plate, breaking the circuit. The primary function of a switch stator is to ensure that the circuit can be reliably connected or disconnected when needed.

[0003] A stamping die is a special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. Stamping is a pressure processing method that uses a die mounted on a press at room temperature to apply pressure to the material, causing it to separate or plastically deform, thereby obtaining the desired part. Stamping dies are often used in the processing of switch static plates.

[0004] In the design of a continuous stamping die for a cap-shaped component, with publication number CN113996708B, its operating principle mainly relies on a single stamping action of the upper die to complete the processing of the sheet. However, when processing sheets with irregular shapes, the die faces certain limitations: if the spacing between the sheets is set too wide, it will lead to significant waste of raw materials; conversely, if the spacing is too narrow, the edge corners of the sheet may appear to bend up or down after the stamping operation. These raised parts not only affect the appearance, but may also interfere with the precise stamping efficiency of the punch, thereby reducing the quality of the finished product. In addition, existing stamping forming technologies generally lack the function of instantly removing burrs from static sheets during the stamping process. Users need to first collect all stamped static sheets and then transfer them to special burr treatment equipment for processing. This extra step not only increases the complexity of the operation and reduces production efficiency, but also brings inconvenience to users. Summary of the Invention

[0005] The purpose of the present invention is to provide a static piece forming device and process thereof, aiming to solve the problem in general technology that the edge corners of the static piece forming equipment plate may warp and affect the stamping effect and the burrs of the static piece cannot be processed in time.

[0006] To achieve the above object, the present invention adopts the following technical solutions: It includes a frame, on which a first driving mechanism, a grinding mechanism, a moving mold and a fixed mold are installed. The moving mold and the fixed mold are arranged opposite to each other. A material plate is placed on the fixed mold. It further includes a material receiving mechanism installed between the grinding mechanism and the fixed mold. The moving mold includes a first mold base, at the bottom of which a punch fixing plate for installing a punch is installed. A limiting mechanism is slidably installed inside the punch fixing plate, and the limiting mechanism is located on both sides of the punch. The material receiving mechanism includes a connecting seat fixedly installed between the grinding mechanism and the fixed mold. A connecting plate is slidably installed up and down inside the connecting seat. A fixed seat is fixedly installed on one side of the connecting plate, and a material receiving plate is fixedly installed inside the fixed seat. Four installation holes are opened inside the connecting seat, and a telescopic member is provided in each installation hole. The fixed end of the telescopic member is fixedly installed inside the grinding mechanism, and the movable end of the telescopic member is inserted into the installation hole. Four first through grooves and two second through grooves communicating with the installation holes are opened on the inner wall of the connecting seat.

[0007] A further technical solution of the present invention is that the limiting mechanism includes a plurality of limiting blocks slidably installed inside the punch fixing plate. The plurality of limiting blocks are distributed on both sides of the punch. A plurality of sliding rods are fixedly installed on the top of each limiting block. A first elastic member is sleeved on the outer surface of each sliding rod. The plurality of sliding rods are all slidably installed inside the first mold base, and the first elastic member is located between the limiting block and the first mold base.

[0008] A further technical solution of the present invention is that four positioning rods are fixedly installed at the bottom of the moving mold. The positioning rods penetrate through the fixed mold and are inserted into the installation holes. The positioning rods press down on the telescopic members as the moving mold presses down.

[0009] A further technical solution of the present invention is that a connecting sleeve is fixedly installed at a position near the end of the outer surface of the movable end of the telescopic member. A connecting rod is inserted into the connecting sleeve. The end of the connecting rod far from the connecting sleeve is fixedly connected to the connecting plate.

[0010] A further technical solution of the present invention is that a C-shaped plate is fixedly installed on the side of the connecting plate where the connecting rod is installed. The C-shaped plate is slidably installed inside the second through groove. A first slider is fixedly installed on the inner side of the middle of the C-shaped plate.

[0011] A further technical solution of the present invention is that an installation plate is fixedly installed at a position near the bottom of the middle of the second through groove. A second slider is fixedly installed on the inner side of the installation plate. The second slider corresponds to the first slider up and down.

[0012] A further technical solution of the present invention is that conveying mechanisms for conveying material sheets are provided on both sides of the material receiving mechanism, and the conveying mechanisms include fixed plates fixedly installed at both ends of the material receiving mechanism, and a connecting shaft is installed between the two fixed plates for common rotation, and a feed roller for conveying material sheets is fixedly installed in the middle of the connecting shaft, and a second driving mechanism for driving it is installed at both ends of the connecting shaft.

[0013] A further technical solution of the present invention is that the second driving mechanism includes a gear and a disc rotatably mounted on a connecting shaft, the gear and the disc are connected by a connecting bar, and the second driving mechanism also includes a ratchet fixedly mounted on the connecting shaft, and a ratchet tooth adapted to the ratchet is installed on the side of the disc away from the connecting bar.

[0014] A further technical solution of the present invention is that racks for driving the gears are installed at both ends of both sides of the first driving mechanism.

[0015] A forming process for a static sheet includes the following steps:

[0016] S1. Material preparation, select the appropriate material board;

[0017] S2, driving the movable die to punch the material plate on the fixed die through the first driving mechanism, and transporting the punched static sheet to the grinding mechanism for deburring through the material receiving mechanism;

[0018] S3, sending the deburred static sheet to a bending machine for bending;

[0019] S4. Surface treatment is performed on the bent static piece;

[0020] S5. Conduct quality inspection on static films;

[0021] S6. The qualified static films will be packaged and shipped.

[0022] The beneficial effects of the present invention are:

[0023] 1. By arranging a material receiving mechanism on the grinding mechanism to install the fixed die, the static piece completed by stamping can be received by a fixed seat equipped with a material receiving plate. As the stamping work progresses, the static piece descends. When it is close to the grinding mechanism, the fixed seat is loosened to make the static piece fall onto the grinding mechanism. As the fixed seat further descends, the material receiving plate abuts against the static piece and positions it, so that the grinding mechanism can grind the barbs on the static piece, thereby achieving the purpose of facilitating the removal of barbs from the static piece. A limit block connected to the sliding surface of the punch fixing plate is provided inside the punch fixing plate, and a slide rod and a first elastic member sleeved on the slide rod are provided on the top of the limit block. During the stamping process of the static piece, the limit block can always abut against the material plate at the edges of both sides of the punch, thereby preventing the material plate from warping up or down.

[0024] 2. By arranging a rotatably connected gear and a disc on the connecting shaft, arranging a fixedly connected ratchet on the connecting shaft, and arranging ratchet teeth adapted to the ratchet on the disc, and arranging racks that mesh with the gears on both sides of the first driving mechanism, the gears can be made to idle when the first driving mechanism descends, and the material sheet can be conveyed when the first driving mechanism ascends, which not only reduces the use of manpower, but also can accurately control the conveying distance of the material sheet.

[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Embodiment 1

[0045] Since most of the forming equipment in the general technology needs to collect the static sheets after stamping and convey them to another deburring processing equipment for processing, and when the sheet spacing is narrow, the edges and corners of the sheet may warp up or down, affecting subsequent processing operations.

[0046] Based on the above problems, in this embodiment Figures 1 to 4As shown in the figure, a forming device for a stationary sheet includes a frame 1. At the top of the frame 1, a first driving mechanism 11 is installed. At a position below the middle of the frame 1, a grinding mechanism 12 is installed. At the bottom of the first driving mechanism 11, a moving mold 2 is fixedly installed. At the top of the grinding mechanism 12, a material receiving mechanism 3 is installed. At the top of the material receiving mechanism 3, a stationary mold 4 is installed. A material plate 5 is placed on the stationary mold 4. The moving mold 2 is driven downward by the first driving mechanism 11 to stamp the material plate 5 on the stationary mold 4. The material receiving mechanism 3承接并输送冲压成型的静片51 to the bottom grinding mechanism 12 for grinding. Finally, the grinding mechanism 12导出打磨完成的静片51. The first driving mechanism 11 is a prior art, so no more description will be given to it.

[0047] As Figure 3 and Figure 4 As shown in the figure, the material receiving mechanism 3 includes a connecting seat 31 fixedly installed at the top of the grinding mechanism 12. The connecting seat 31 is in a shape of a rectangle with a hole in the middle. Inside the connecting seat 31, four mounting holes 311 for installing telescopic members 32 are provided. The four telescopic members 32 correspond to the positions of the four positioning rods 21 respectively. The fixed ends of the telescopic members 32 are fixedly installed inside the grinding mechanism 12, and the movable ends of the telescopic members 32 are inserted into the inside of the mounting holes 311. On the inner wall of the connecting seat 31, four first through grooves 312 and two second through grooves 313 that communicate with the mounting holes 311 are provided. Near the end position on the outer surface of the movable end of the telescopic member 32, a connecting sleeve 33 is fixedly installed. Inside the connecting sleeve 33, a connecting rod 34 is inserted. At the end of the connecting rod 34 away from the connecting sleeve 33, a connecting plate 35 is fixedly installed. A second elastic member 36 is installed between the connecting plate 35 and the telescopic member 32. The second elastic member 36 is located inside the connecting sleeve 33 and is sleeved on the outer surface of the connecting rod 34. On the other side of the connecting plate 35, a fixed seat 37 is fixedly installed. Inside the fixed seat 37, a material receiving plate 371 for receiving the stationary sheet 51 is fixedly installed.

[0048] On the side of the connecting plate 35 where the connecting rod 34 is fixedly installed, a U-shaped plate 38 is fixedly installed. The U-shaped plate 38 is slidably installed inside the second through groove 313. Inside the middle of the U-shaped plate 38, a first slider 381 is fixedly installed. At a position below the middle of the second through groove 313, a mounting plate 39 is fixedly installed. The mounting plate 39 is L-shaped. Inside the longer section of the mounting plate 39, a second slider 391 is fixedly installed. The second slider 391 and the first slider 381 correspond to each other vertically.

[0049] As Figure 2 and Figures 5 to 7 It should be noted that there are some inaccuracies in the original Chinese text. For example, "承接并输送冲压成型的静片51" and "导出打磨完成的静片51" lack corresponding accurate English expressions in the translation. The above translation is for reference only, and it is recommended to further optimize and clarify according to the actual situation.As shown, the movable mold 2 includes a first mold base 20, and four positioning rods 21 are fixedly installed on the bottom of the first mold base 20. The four positioning rods 21 are inserted into the fixed mold 4 and the material receiving mechanism 3, and drive the material receiving mechanism 3. The four positioning rods 21 are respectively located at the four corners of the bottom of the movable mold 2. A punch fixing plate 22 for installing the punch 23 is installed at the bottom of the first mold base 20. A limiting mechanism 24 for squeezing and fixing the material plate 5 is also slidably installed inside the punch fixing plate 22 to prevent its edge corners from warping up and affecting the operation of the punch 23. A plurality of connecting holes 201 for installing the limiting mechanism 24 are opened inside the first mold base 20.

[0050] like Figure 6 As shown, the limiting mechanism 24 includes a plurality of limiting blocks 241 slidably mounted inside the punch fixing plate 22, and the plurality of limiting blocks 241 are distributed on both sides of the punch 23, so that the limiting blocks 241 can squeeze and fix the material sheet 5 at the edges on both sides thereof during the stamping process of the punch 23, so as to avoid the upward warping of the edge corners of the material sheet 5, and a plurality of sliding rods 242 are fixedly mounted on the top of each limiting block 241, and the outer surface of each sliding rod 242 is sleeved with a first elastic member 243, and each sliding rod 242 is slidably mounted inside a connecting hole 201 opposite to its position, and the first elastic member 243 is located between the limiting block 241 and the first die base 20, so that the limiting block 241 can be driven by the first elastic member 243 to reset when the punch 23 rises.

[0051] like Figure 7 As shown, the fixed die 4 includes a second die base 40, the positioning rod 21 is inserted into the interior of the second die base 40, and a die 41 is fixedly installed on the upper surface of the second die base 40. The punch 23 descends into the interior of the die 41 to complete the stamping of the material sheet 5. The material sheet 5 at the edges of the punch 23 on both sides is located between the limit block 241 and the die 41, so the material sheet 5 will not warp up or down.

[0052] During stamping, the limit block 241 abuts against the upper surface of the blanking plate 5 as the punch 23 descends. As the punch 23 continues to descend, the limit block 241 compresses the first elastic member 243. At the same time, the positioning rod 21 enters the interior of the mounting hole 311 and presses down on the telescopic member 32, causing the mounting plate 39 to enter the interior of the C-shaped plate 38. When the first slider 381 meets the second slider 391, since the mounting plate 39 is fixed, the first slider 381 drives the C-shaped plate 38, which in turn drives the connecting plate 35 to move towards the second through groove 313 and compresses the second elastic member 36. At this time, the receiving plate 371 loses its support for the static plate 51, and the static plate 51 drops onto the grinding mechanism 12. As the positioning rod 21 continues to press down, the first slider 381 and the second slider 391 are displaced, and the connecting plate 35 is reset under the drive of the second elastic member 36. When the positioning rod 21 descends to the lowest position, the bottom of the receiving plate 371 abuts against the static plate 51 to position the static plate 51, and then the grinding mechanism 12 is activated to grind the positioned static plate 51 to remove burrs. With the completion of the stamping operation, the positioning rod 21 rises, the telescopic member 32 automatically resets to receive the newly stamped static plate 51, the first elastic member 243 drives the limit block 241 to reset, and the grinding mechanism 12 exports the grinded static plate 51.

[0053] In this embodiment, by installing the receiving mechanism 3 on the grinding mechanism 12 to mount the fixed die 4, the static plate 51 after stamping can be received by the fixed seat 37 equipped with the receiving plate 371. As the static plate 51 descends during the stamping operation and approaches the grinding mechanism 12, the fixed seat 37 is released, causing the static plate 51 to drop onto the grinding mechanism 12. As the fixed seat 37 further descends, the receiving plate 371 abuts against the static plate 51 and positions it, facilitating the grinding mechanism 12 to grind the burrs on the static plate 51, achieving the purpose of facilitating the removal of burrs from the static plate 51. Additionally, a limit block 241 slidably connected to the interior of the punch fixing plate 22 is provided, and a slide bar 242 and a first elastic member 243 sleeved on the slide bar 242 are arranged at the top of the limit block 241, which can keep the limit block 241 always abutting against the blanking plate 5 at the two side edges of the punch 23 during the stamping process of the static plate 51, thereby preventing the blanking plate 5 from warping upwards or downwards.

[0054] Embodiment 2

[0055] During the use process, it is found that during stamping, manual movement of the blanking plate 5 is still required. This is not only inconvenient for processing and use, but also the distance of manual movement is uncontrollable, which may result in partial loss of the static plate 5 due to deviation, or excessive waste of materials due to excessive movement distance.

[0056] Such as Figures 8 to 10As shown, the difference between this embodiment and embodiment 1 is that a conveying mechanism 6 for conveying the material sheet 5 is provided on both sides of the material receiving mechanism 3, and the conveying mechanism 6 includes two fixed plates 61 fixedly mounted at both ends of one side of the material receiving mechanism 3, and a connecting shaft 62 is rotatably mounted inside the two fixed plates 61, and a feeding roller 63 for conveying the material sheet 5 is fixedly mounted in the middle of the connecting shaft 62, and a second driving mechanism for driving the connecting shaft 62 is installed at both ends.

[0057] The second driving mechanism includes a gear 64 and a disc 65 rotatably mounted on the connecting shaft 62. The gear 64 and the disc 65 are connected by a connecting bar 651. The second driving mechanism also includes a ratchet 66 fixedly mounted on the connecting shaft 62. A ratchet 67 adapted to the ratchet 66 is mounted on the side of the disc 65 away from the connecting bar 651. Racks 68 for driving the gear 64 are mounted at both ends of the first driving mechanism 11. When the first driving mechanism 11 drives the movable mold 2 to descend, the ratchet 67 rotates relative to the ratchet 66. When the first driving mechanism 11 drives the movable mold 2 to rise, the ratchet 67 and the ratchet 66 are abutted against each other, so that the gear 64 can drive the ratchet 66 to rotate through the ratchet 67, thereby driving the feed roller 63 to convey the material sheet 5.

[0058] In this embodiment, a rotatably connected gear 64 and a disc 65 are provided on the connecting shaft 62, a fixedly connected ratchet 66 is provided on the connecting shaft 62, and a ratchet 67 adapted to the ratchet 66 is provided on the disc 65, and racks 68 meshing with the gear 64 are provided on both sides of the first drive mechanism 11. The gear 64 can be made to idle when the first drive mechanism 11 descends, and the material sheet 5 can be conveyed when the first drive mechanism 11 ascends, which not only reduces the use of manpower but also enables the conveying distance of the material sheet 5 to be precisely controlled.
