Description
Technical Field
[0001] This utility model relates to the field of stamping technology, and in particular to an adjustable stamping die. Background Technology
[0002] Stamping dies are process equipment used in stamping to cause plastic deformation, separation, or forming of materials. They mainly consist of an upper die, a lower die, a guiding mechanism, and a stripping device. They are characterized by high precision, high efficiency, and high consistency. Through various processes such as blanking, bending, drawing, and forming, they can process sheet metal and strips into parts of various shapes and sizes. Widely used in industries such as automotive, electronics, home appliances, and aerospace, they are key process equipment for achieving minimal or no cutting in modern manufacturing. Their design and manufacturing level directly affects product quality, production efficiency, and cost.
[0003] The existing utility model patent with publication number CN217912495U discloses a stamping die with a replaceable stamping die head. "The stamping die with a replaceable stamping die head first uses a screwdriver to remove the screw, then completely disengages the screw from the punch, and then the punch can be quickly replaced through the cooperation between the protrusion and the spring, achieving the purpose of convenient replacement." Although it solves the problem that "it is very inconvenient to disassemble because the stamping head and the die are tightly connected," the impact force during the stamping process acts directly on the bottom die, which will cause the bottom die to be prone to fatigue and wear, shortening its service life. Therefore, it needs to be frequently maintained or replaced. When replacing the bottom die of a traditional stamping die, it is necessary to manually remove the bolts one by one, which is cumbersome and time-consuming and cannot meet the needs of rapid changeover. Therefore, an adjustable stamping die is proposed. Utility Model Content
[0004] Therefore, it is necessary to provide an adjustable stamping die to address the aforementioned technical problems.
[0005] To solve the above-mentioned technical problems, this utility model solves the problem of the cumbersome and time-consuming process of changing the bottom mold, which makes it difficult to meet the needs of rapid mold changeover through the following technical solution.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] An adjustable stamping die, comprising:
[0008] A base plate, a stamping device is installed on the top of the base plate, a mold plate is provided on the top of the base plate, a concave hole is opened at the center of the top of the mold plate, and connecting support plates are fixedly connected to the base plate on both sides of the bottom end of the mold plate.
[0009] An adjusting plate is placed inside the concave cavity. A rotating rod is fixedly inserted through the surface of the adjusting plate. An upper mold and a lower mold are respectively provided at the top and bottom of the adjusting plate. One end of the rotating rod rotates through one side of the inner wall of the concave cavity to the outside of the mold plate and is fixedly connected to a worm gear. A driving component is provided at the top of the worm gear.
[0010] In a preferred embodiment of the adjustable stamping die provided by this utility model, the other end of the rotating rod is rotatably connected to the other side of the inner wall of the concave hole, and an installation groove is provided in the middle of the top of the base plate, and an auxiliary support is provided in the inner cavity of the installation groove.
[0011] In a preferred embodiment of the adjustable stamping die provided by this utility model, the driving component includes a mounting plate fixedly connected to the left connecting support plate, and a driving part is installed on one side wall of the mounting plate.
[0012] In a preferred embodiment of the adjustable stamping die provided by this utility model, the output shaft of the drive unit rotatably passes through the surface of the mounting plate to its inner side and is connected to a worm gear for transmission.
[0013] In a preferred embodiment of the adjustable stamping die provided by this utility model, one end of the worm gear is rotatably connected to the inner wall of the mounting plate, and the worm gear meshes with the worm wheel.
[0014] As a preferred embodiment of the adjustable stamping die provided by this utility model, the auxiliary support includes two drive parts II installed in the inner cavity of the mounting groove. The two drive parts II are distributed on both sides of the bottom of the adjustment plate, and a support ball is connected to the output end of the drive parts II.
[0015] In a preferred embodiment of the adjustable stamping die provided by this utility model, a rubber ring is fixedly connected to the top of the support ball.
[0016] In a preferred embodiment of the adjustable stamping die provided by this utility model, a built-in groove is provided at the center of the top of the support ball, and a rangefinder is installed in the inner cavity of the built-in groove.
[0017] In a preferred embodiment of the adjustable stamping die provided by this utility model, fixing blocks are fixedly connected to both sides of the opposite surfaces of the upper and lower dies, and a pair of grooves are provided at the top and bottom of the adjusting plate.
[0018] In a preferred embodiment of the adjustable stamping die provided by this utility model, the fixing block is L-shaped with its bottom placed in the inner cavity of the groove, and the upper die and the lower die are detachably fixedly connected to the adjusting plate through the fixing block, the groove and the adjusting plate.
[0019] Compared with the prior art, the present invention has the following beneficial effects:
[0020] This utility model provides an adjustable stamping die. When it is necessary to switch between the upper and lower dies, the drive unit is controlled to rotate the worm gear, which cooperates with the worm wheel to allow the adjustment plate to switch the positions of the upper and lower dies, thereby achieving the purpose of rapid switching. This avoids the cumbersome operation of disassembly and reinstallation required for traditional die replacement. It is suitable for multi-variety, small-batch production, such as electronic components and automotive parts, which require frequent die replacement. The alternating use of dual dies can reduce fatigue damage of a single die. By integrating dual dies through the adjustment plate and combining them with the worm gear drive, "one machine for multiple uses" is achieved, breaking through the limitation of "one die per machine" in traditional dies.
[0021] This utility model provides an adjustable stamping die. By providing an auxiliary support component, after the adjustment plate is rotated and adjusted, the drive unit two cooperates with the rangefinder to make the support ball abut against the bottom part of the adjustment plate for auxiliary support. When the angle of the adjustment plate needs to be adjusted, the rangefinder cooperates with the drive component and the auxiliary support component to upgrade the angle adjustment of the die from "manual experience" to "data-driven", thereby improving production stability.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example
[0032] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 An adjustable stamping die includes a base plate 1, a stamping device is installed on the top of the base plate 1, a die plate 2 is provided on the top of the base plate 1, a recess 3 is provided at the center of the top of the die plate 2 to accommodate an adjustment plate 5 and its rotating mechanism, and connecting support plates 4 are fixedly connected between the two sides of the bottom end of the die plate 2 and the base plate 1, which cooperate with the mounting groove 10 to reserve space for the adjustment plate 5 to flip, while also providing installation and movement space for the auxiliary support 12;
[0033] The adjusting plate 5 carries the upper mold 7 and the lower mold 11. The mold switching and tilt angle adjustment are realized by rotation. The adjusting plate 5 is placed in the inner cavity of the concave hole 3. A rotating rod 6 is fixedly inserted through the surface of the adjusting plate 5, which serves as the rotating shaft of the adjusting plate 5 and is connected to the worm gear 8 to transmit driving force. The upper mold 7 and the lower mold 11 are respectively set at the top and bottom of the adjusting plate 5. The dual mold design can be used alternately to reduce fatigue damage of a single mold and extend the mold life. One end of the rotating rod 6 rotates through one side of the inner wall of the concave hole 3 to the outside of the mold plate 2 and is fixedly connected to the worm gear 8. A driving component 9 is set on the top of the worm gear 8.
[0034] Preferably, the other end of the rotating rod 6 is rotatably connected to the other side of the inner wall of the concave hole 3, and an installation groove 10 is provided in the middle of the top of the bottom plate 1 to accommodate the auxiliary support 12. The auxiliary support 12 is provided in the inner cavity of the installation groove 10.
[0035] Preferably, the driving component 9 includes a mounting plate 91 fixedly connected to the left connecting support plate 4. The mounting plate 91 has a U-shaped design. A driving part 92 is installed on one side wall of the mounting plate 91. The driving part 92 is specifically a motor, which provides a power source to drive the worm gear 93 to rotate. The output shaft of the driving part 92 rotates through the surface of the mounting plate 91 to its inner side and is connected to the worm gear 93. One end of the worm gear 93 is rotatably connected to the inner wall of the mounting plate 91, and the worm gear 93 meshes with the worm wheel 8.
[0036] Preferably, the auxiliary support component 12 includes two drive units 121, specifically cylinders, installed in the inner cavity of the mounting groove 10. These cylinders cooperate with the rangefinder 125 to dynamically adjust the support point according to the angle after the adjustment plate 5 is rotated, achieving precise support driven by data. The two drive units 121 are distributed on both sides of the bottom of the adjustment plate 5. A support ball 122 is connected to the output end of the drive unit 121. A rubber ring 123 is fixedly connected to the top of the support ball 122 to buffer the impact force during the stamping process. An internal groove 124 is opened at the center of the top of the support ball 122. The rangefinder 125 is installed in the inner cavity of the internal groove 124. Through data feedback, the drive unit 121 is linked to achieve automatic calibration of the support position, upgrading the mold angle adjustment from "manual experience" to "data-driven", improving production stability and accuracy.
[0037] Preferably, fixing blocks 13 are fixedly connected to both sides of the opposite surfaces of the upper mold 7 and the lower mold 11. A pair of grooves 14 are provided at the top and bottom of the adjusting plate 5. The fixing blocks 13 are L-shaped and their bottoms are placed in the inner cavity of the grooves 14. The upper mold 7 and the lower mold 11 are detachably fixed to the adjusting plate 5 through the fixing blocks 13 and the grooves 14, so as to realize the detachable connection between the mold and the adjusting plate 5.
[0038] The adjustable stamping die provided by this utility model is used as follows: When it is necessary to switch between the upper die 7 and the lower die 11, the drive unit 1 92 is started, and the output shaft drives the worm gear 93 to rotate. Since the worm gear 93 meshes with the worm wheel 8, the worm wheel 8, driven by the worm gear 93, drives the adjusting plate 5 to rotate through the rotating rod 6. After the adjusting plate 5 rotates 180 degrees, the positions of the upper die 7, which was originally located at the top, and the lower die 11, which was located at the bottom, are swapped, completing the die switching. When adjusting the die tilt angle, the drive unit 1 92 also drives the worm gear 93, the worm wheel 8, and the rotating rod 6 to drive the adjusting plate 5 to rotate to the required angle. After the adjusting plate 5 rotates, the drive unit 2 121 works in conjunction with the rangefinder 125. The rangefinder 125 monitors the distance between the adjusting plate 5 and the support ball 122 in real time and feeds the data back to the control system. The control system controls the drive unit 2 121 according to the data to drive the support ball 122 to rise and fall, so that it abuts against the bottom of the adjusting plate 5 and adjusts the position of the support point to achieve precise support driven by data.
