Abstract
Description
A press stamping die equipment Technical Field
[0001] This application relates to the field of filter stamping technology, and in particular to a press stamping die equipment. Background Technology
[0002] In the field of machinery manufacturing, press stamping die equipment plays a crucial role. With its high efficiency and precision, press stamping die equipment enables rapid forming and processing of materials such as sheet metal, thereby improving production efficiency.
[0003] Currently, a press mainly includes a base, a frame fixed above the base, an operating handle, a stamping head, a transmission device, and a mold. When it is necessary to stamp a thin-film filter, the copper sheet is first placed in a suitable position in the mold. Then, the operating handle, through the transmission device, drives the stamping head to press down, causing the mold to stamp the copper sheet, thereby forming the filter sheet. However, after the thin-film filter is formed, it is often tightly stuck inside the mold, making it extremely inconvenient to remove. At the same time, because the copper sheet itself is thin and light, and the filter is a precision component, if too much force is applied during the removal process, the filter is easily deformed and becomes scrap. On the other hand, if too little force is applied, it is difficult to remove it from the mold, resulting in low processing efficiency and low yield. Summary of the Invention
[0004] In order to improve the processing efficiency and yield of filter wafers, this application provides a press stamping die equipment.
[0005] This application provides a press stamping die equipment, which adopts the following technical solution:
[0006] A press stamping die equipment includes a base, a press body fixed above the base, an operating handle on the press body, a transmission device, a stamping head, and a die disposed above the base.
[0007] The mold has a forming cavity, and the forming cavity has a lower forming plate, an upper forming plate and a perforated plate arranged sequentially from bottom to top. Multiple stamping forming rods are fixed below the perforated plate. The lower forming plate and the upper forming plate are both provided with stamping holes that are adapted to the stamping forming rods. The bottom of the mold has an ejection hole arranged from bottom to top.
[0008] By adopting the above technical solution, when stamping and forming filter sheets, the copper sheet is first placed above the mold, and the upper forming plate and the punching plate are placed above the copper sheet. Then, the punch head is pressed down by operating the handle. The upper forming plate cuts the edge of the copper sheet and, together with the lower forming plate, stamps and forms the internal texture of the filter sheet. The punching plate punches holes in the formed copper sheet, completing the forming and punching operations of the filter sheet in one go. After the filter sheet is formed, the lower forming plate and the formed filter sheet can be ejected upwards from the forming cavity through the ejector hole. Then, the filter sheet can be removed from the outside of the forming cavity, thus avoiding damage to the filter sheet. On the one hand, this equipment can complete the forming and punching operations of the filter sheet in one go, improving processing efficiency. On the other hand, the ejector hole allows the operator to easily remove the filter sheet from the outside of the forming cavity, avoiding deformation of the filter and rendering it scrap due to improper force when removing parts from the mold, thus improving the yield.
[0009] Optionally, the top of the mold is fixed with vertically arranged positioning guide rods at both ends along its diagonal direction, and the top of the perforated plate is detachably connected with a positioning plate. The positioning plate has positioning holes at both ends that are adapted to the positioning guide rods, and the positioning guide rods are inserted into the positioning holes.
[0010] By adopting the above technical solution, when installing the perforated plate, the positioning holes at both ends of the positioning plate are aligned with the vertical positioning guide rods fixed at both ends along the diagonal direction on the top of the mold. Then, the positioning guide rods are inserted into the positioning holes, which can realize the positioning of the perforated plate and the mold, and quickly align the perforated plate with the lower forming plate. This avoids the perforated plate from shifting or shaking during stamping, ensuring the accuracy of the perforated plate in punching the formed copper sheet, and improving the yield and quality of the thin-film filter.
[0011] Optionally, two positioning posts are fixed on the top of the upper forming plate, and an oblong positioning groove adapted to the positioning posts is provided on the perforated plate. The positioning posts are inserted into the oblong positioning grooves, and the two positioning posts abut against the two oblong positioning grooves on opposite sides.
[0012] By adopting the above technical solution, the double-sided positioning can ensure the accurate relative position between the upper forming plate and the perforated plate, ensuring high precision in their fit during stamping. This guarantees the accuracy and consistency of filter sheet forming and punching during copper sheet stamping, thereby improving product quality and processing precision.
[0013] Optionally, two positioning blocks are provided above the base, and the sliding direction of the two positioning blocks is set vertically. The adjacent sides of the mold abut against the two positioning blocks respectively.
[0014] By adopting the above technical solution, in actual operation, the positions of the two positioning blocks can be flexibly adjusted according to the size and specifications of the mold, so that they fit tightly against the adjacent sides of the mold, improving the applicability of the equipment. Moreover, the two positioning blocks can limit the mold from different directions, allowing the mold to maintain a stable installation state on the base, reducing stamping errors caused by mold shaking or displacement, and improving the quality and precision of stamped products. At the same time, it can also realize the rapid positioning of the mold on the base, effectively shortening the mold installation and debugging time and significantly improving work efficiency.
[0015] Optionally, the positioning block is slidably connected to the base, and a first adjusting screw is rotatably connected to the base, the first adjusting screw being threadedly connected to the positioning block.
[0016] By adopting the above technical solution, rotating the first adjusting screw will convert the rotation of the first adjusting screw into the sliding of the positioning block in a specific direction, since the first adjusting screw is threadedly connected to the positioning block and the positioning block is slidably connected to the base. This will adjust the position of the positioning block, so that the two positioning blocks can accurately abut against the adjacent sides of the mold, thereby achieving precise positioning of the mold side.
[0017] Optionally, a movable clamp is slidably connected above the base, and a second adjusting screw is rotatably connected to the base. The second adjusting screw is threadedly connected to the bottom of the movable clamp, and the clamp head of the movable clamp abuts against the side of the mold.
[0018] By adopting the above technical solution, when the second adjusting screw is rotated, it can drive the movable clamp to slide on the base because it is threadedly connected to the bottom of the movable clamp until the clamp head abuts against the side of the mold. The movable clamp, together with the two positioning blocks, quickly positions the three sides of the mold, so that the mold remains stable during operation. The operation of fixing and unlocking the mold by the movable clamp is simple and convenient.
[0019] Optionally, the edges of the upper forming plate are polished and have micro-bevels to improve sharpness.
[0020] By adopting the above technical solution, when the stamping head presses down, the upper forming plate will cut the edge of the copper sheet. The upper forming plate, which has been polished and has a micro-chamfer, improves the sharpness of the edge and reduces the friction between the upper forming plate and the copper sheet during cutting. This allows the upper forming plate to cut into the copper sheet more easily when it comes into contact with the copper sheet, reducing problems such as uneven cutting and burrs caused by insufficient edge sharpness or rough surface. This improves the accuracy and quality of cutting the edge of the copper sheet, thereby improving the quality of the filter.
[0021] In summary, this application includes at least one of the following beneficial technical effects:
[0022] 1. On the one hand, the equipment can complete the forming and punching of the filter sheet in one go, improving processing efficiency. On the other hand, the ejector hole allows workers to easily remove the filter sheet from the outside of the forming cavity, avoiding deformation of the filter due to improper force when removing parts from the mold, thus improving the yield rate.
[0023] 2. When installing the perforated plate, the positioning plate, positioning hole, vertical positioning guide rod, positioning column and waist-shaped positioning groove are used in combination to achieve the positioning of the perforated plate and the mold, so that the perforated plate, upper forming plate and lower forming plate are quickly aligned, avoiding offset or shaking during stamping, ensuring the accuracy and consistency of filter sheet forming and punching, and improving product quality and processing precision.
[0024] 3. In actual operation, the positions of the two positioning blocks can be flexibly adjusted according to the size and specifications of the mold, so that they fit tightly against the adjacent sides of the mold, improving the applicability of the equipment. The two positioning blocks can limit the mold from different directions, keeping the mold in a stable installation state on the base, reducing stamping errors caused by mold shaking or displacement, and improving the quality and precision of stamped products. At the same time, it can also realize the quick positioning of the mold on the base, effectively shortening the mold installation and debugging time and significantly improving work efficiency. The movable clamp, together with the two positioning blocks, quickly positions the three sides of the mold, keeping the mold stable during operation. The operation of fixing and unlocking the mold through the movable clamp is simple and convenient. Attached Figure Description

[0029] The present application will be further described in detail below with reference to Figures 1-3.
[0030] This application discloses a press stamping die device. Referring to Figures 1 and 2, the press stamping die device includes a base 1, a press body 2 fixed above the base 1, an operating handle 3 mounted on the press body 2, a stamping head 4, a transmission device for driving the stamping head 4 downward, and a die 5 mounted above the base 1. The press body 2 provides support for the entire device. The operating handle 3, transmission device, and stamping head 4 are mounted on the press body 2. The operating handle 3 controls the operation of the transmission device, which transmits operating force to the stamping head 4 to achieve the stamping action.
[0031] Specifically, referring to Figures 2 and 3, the mold 5 has a forming cavity 51, which is the space for forming the filter sheet. From bottom to top, the forming cavity 51 contains a lower forming plate 52, an upper forming plate 53, and a perforated plate 54. Both the lower forming plate 52 and the upper forming plate 53 have internal textures; the edges of the upper forming plate 53 are polished and have micro-bevels to improve sharpness, which is beneficial for cutting the copper sheet edges. Multiple stamping forming rods 541 are fixed below the perforated plate 54. The stamping forming rods 541 are cylindrical and made of hard alloy steel. Both the lower forming plate 52 and the upper forming plate 53 have stamping holes 55 that match the stamping forming rods 541. The diameter and position of the stamping holes 55 correspond one-to-one with the stamping forming rods 541, so that the stamping forming rods 541 can pass through smoothly for stamping.
[0032] When stamping and forming the filter sheet, the copper sheet is first placed on top of the mold 5, and the upper forming plate 53 and the punching plate 54 are placed on top of the copper sheet. Then, the punching head 4 is pressed down by operating the handle 3. The upper forming plate 53 cuts the edge of the copper sheet and works with the lower forming plate 52 to stamp and form the internal texture of the filter sheet. The punching plate 54 punches holes in the formed copper sheet. The three work together to complete the forming and punching of the filter sheet in one go.
[0033] Referring to Figure 3, the bottom of the mold 5 has an ejector hole 56 extending upwards. Through the ejector hole 56, tools such as ejector pins can be used to eject the lower forming plate 52 and the formed filter together upwards out of the forming cavity 51. This allows workers to easily remove the filter sheet from the outside of the forming cavity 51, avoiding damage to the filter when removing it from inside the mold 5. After the filter sheet is removed, the lower forming plate 52 returns to the bottom of the forming cavity 51, ready for the next stamping process.
[0034] Referring to Figures 2 and 3, positioning guide rods 57, arranged vertically, are fixed at both ends of the top of the mold 5 along its diagonal direction. A positioning plate 58 is detachably connected to the top of the punching plate 54 via bolts. Positioning plates 58 have positioning holes 581 at both ends along their length, which are adapted to the positioning guide rods 57. The positioning holes 581 are circular through holes with a diameter matching the outer diameter of the positioning guide rods 57. The positioning guide rods 57 are inserted into the positioning holes 581. The positioning holes 581 and positioning guide rods 57 enable the positioning of the punching plate 54 and the mold 5, allowing the punching plate 54 to quickly align with the lower forming plate 52. This prevents the punching plate 54 from shifting or shaking during stamping, ensuring the accuracy of the punching plate 54 in punching the formed copper sheet.
[0035] Referring to Figures 2 and 3, two positioning posts 531 are fixed on the top of the upper forming plate 53. The perforated plate 54 has an oblong positioning groove 542 that matches the positioning posts 531. The positioning posts 531 are inserted into the oblong positioning groove 542, and the two positioning posts 531 abut against the two oblong positioning grooves 542 on opposite sides, forming a double-sided positioning. This positioning method can make the relative position between the upper forming plate 53 and the perforated plate 54 more accurate, thereby improving the stamping precision.
[0036] Referring to Figures 1 and 2, two positioning blocks 6 are slidably connected to the top of the base 1. The sliding direction of the two positioning blocks 6 is vertically set. A first adjusting screw 61 is rotatably connected to the base 1. The first adjusting screw 61 is threadedly connected to the positioning blocks 6. By rotating the first adjusting screw 61, the positioning blocks 6 can slide on the base 1. The adjacent sides of the mold 5 abut against the two positioning blocks 6 respectively. The two positioning blocks 6 are used to laterally position the mold 5, ensuring that the mold 5 is accurately positioned on the base 1.
[0037] Referring to Figure 2, a movable clamp 7 is slidably connected above the base 1. The movable clamp 7 includes a clamping arm, a clamping head, and a connecting seat. The connecting seat is slidably engaged with the base 1. A second adjusting screw 71 is rotatably connected to the base 1. The second adjusting screw 71 is threadedly connected to the bottom connecting seat of the movable clamp 7. By rotating the second adjusting screw 71, the movable clamp 7 can slide on the base 1. The clamping head of the movable clamp 7 abuts against the side of the mold 5, and together with the two positioning blocks 6, quickly positions the three sides of the mold 5 to ensure that the mold 5 does not shift during the stamping process.
[0038] The implementation principle of the press stamping die equipment in this application embodiment is as follows: When stamping and forming a filter sheet, the copper sheet is first placed on the die 5, and the upper forming plate 53 and the punching plate 54 are placed on the copper sheet. Then, the punching head 4 is pressed down by operating the handle 3. The upper forming plate 53 cuts the edge of the copper sheet and, together with the lower forming plate 52, stamps and forms the internal texture of the filter sheet. The punching plate 54 punches holes in the formed copper sheet, completing the forming and punching operations of the filter sheet in one go. After the filter sheet is formed, the lower forming plate 52 and the formed filter sheet together can be ejected upward from the forming cavity 51 through the ejection hole 56. Then, the filter sheet is removed from the outside of the forming cavity 51, thus avoiding damage to the filter sheet. On the one hand, the equipment can complete the forming and punching operations of the filter sheet in one go, improving processing efficiency. On the other hand, the ejection hole 56 makes it convenient for the operator to remove the filter sheet from the outside of the forming cavity 51, avoiding the filter deformation and becoming scrap due to improper force when removing parts from the die 5, thus improving the yield.
[0039] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
