Description

Technical Field

[0001] This utility model relates to the field of adjustable sheet metal mold technology, and in particular to an adjustable sheet metal mold. Background Technology

[0002] Stamping dies play a crucial role in sheet metal processing. Like precise "shaping tools," they use the powerful pressure applied by the stamping equipment to plastically deform sheet metal material according to the specific cavity contours of the die. On one hand, dies can precisely cut sheet metal, slicing large pieces of raw material into the required dimensions and shapes, producing neat, precisely sized, and clean-cut thin metal parts. On the other hand, they can shape three-dimensional forms through processes such as stretching and bending, manufacturing products with curved or bent structures, such as appliance housings.

[0003] The purpose of stamping sheet metal is to efficiently and in large quantities produce high-quality sheet metal parts. Compared to handcrafting, stamping is extremely fast, capable of replicating hundreds or even thousands of parts of the same specifications in a short time, meeting the needs of large-scale production. Furthermore, stamping offers high precision, minimizing dimensional deviations and ensuring stable product assembly and performance. Moreover, the stamping process is quite flexible; a single set of molds can be easily adjusted to accommodate different sheet metal specifications, reducing production costs while meeting diverse market customization demands.

[0004] Traditional mold clamping devices often rely on simple mechanical positioning when loading sheet metal. This has limited positioning accuracy for irregular or thin sheet metal. Even a slight deviation in initial placement can cause parts to be scrapped during stamping, making it difficult to meet the needs of complex and delicate sheet metal processing.

[0005] During high-speed stamping, the existing clamping structure provides insufficient friction, and the sheet metal parts are prone to displacement within the mold due to impact, resulting in misalignment of the formed parts. This is especially true for large and narrow sheet metal parts, where the probability of scrap is even higher due to unstable clamping.

[0006] Furthermore, after processing is completed, the existing mold requires manual removal of the sheet metal parts. If pneumatic components are used to push them out, the stability of the push-out cannot be effectively guaranteed, thus reducing processing efficiency. Utility Model Content

[0007] In view of this, the technical problem to be solved by this utility model is: how to provide an adjustable sheet metal mold to achieve clamping stability of sheet metal parts during the stamping process and ensure ejection stability after processing.

[0008] To achieve the above objectives, this utility model proposes an adjustable sheet metal mold, which includes a base, a stamping plate, a stamping block, a sleeve, a guide post, a compression spring, a bracket, a first cylinder, a second cylinder, a first support block, and a second support block.

[0009] The guide posts are fixedly mounted on the base and located on both sides of the base respectively. The guide posts are arranged in a vertical direction, and the bracket is fixedly mounted on the base.

[0010] The sleeve is connected to the stamping plate and located at both ends of the stamping plate. The axis of the sleeve is set in the vertical direction. The outer wall of the sleeve is connected to the stamping plate by a thread to adjust the connection position of the sleeve with the stamping plate in the vertical direction.

[0011] The compression spring is sleeved on the guide post, and the sleeve is sleeved and connected to the guide post and located on top of the compression spring. The sleeve is used to press the compression spring, and the compression spring buffers the stamping plate. The stamping block is fixedly installed on the stamping plate.

[0012] The first cylinder and the second cylinder are fixedly mounted on the bracket. The first cylinder is located above the second cylinder in the vertical direction. The output ends of the first cylinder and the second cylinder are both arranged in the horizontal direction. The output end of the first cylinder is connected to the first support block, and the output end of the second cylinder is connected to the second support block. The side wall of the first support block is provided with a rubber pad. The maximum travel of the output end of the second cylinder is greater than the maximum travel of the output end of the first cylinder.

[0013] Furthermore, the cross-sectional area of ​​the first support block in the vertical direction is greater than the cross-sectional area of ​​the second support block in the vertical direction.

[0014] Furthermore, the stamping block is located between the two guide posts.

[0015] Furthermore, a limiting block is provided at the front end of the second support block, the limiting block being used to limit the horizontal movement distance of the first support block located above the second support block.

[0016] Compared with related technologies, the adjustable sheet metal mold proposed in this utility model has the following advantages: Guide pillars are fixed on both sides of the base and arranged vertically, providing stable vertical guidance for the stamping plate, ensuring accurate up-and-down movement of the stamping plate during stamping, avoiding deviation, and guaranteeing stamping precision. The sleeve is threadedly connected to the stamping plate, allowing for vertical adjustment of its position, making the stamping plate height adjustable according to different sheet metal thicknesses and processing requirements, thus enhancing the mold's adaptability. A compression spring, sleeved on the guide pillar and pressed by the sleeve, acts as a buffer for the stamping plate, reducing the impact force during stamping, preventing damage to the mold and sheet metal parts due to excessive impact, and extending the mold's service life. The first and second cylinders provide lateral support through support blocks, and rubber pads protect the sheet metal surface. Different stroke designs meet different sheet metal needs, improving support stability. After stamping, the output ends of the first and second cylinders extend and retract, pushing the support blocks to efficiently eject the sheet metal parts. This method has a high degree of automation, precise operation, and flexible adjustment of ejection force and distance, avoiding human error and damage, and improving production efficiency and product quality.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Please see Figure 1-2 As shown, this utility model proposes an adjustable sheet metal mold, which includes a base 11, a stamping plate 12, a stamping block 13, a sleeve 14, a guide post 15, a compression spring 16, a bracket 17, a first cylinder 21, a second cylinder 22, a first support block 31, and a second support block 32.

[0021] The guide posts 15 are fixedly mounted on the base 11 and located on both sides of the base 11. The guide posts 15 are arranged in a vertical direction, and the bracket 17 is fixedly mounted on the base 11.

[0022] The sleeve 14 is connected to the stamping plate 12 and located at both ends of the stamping plate 12. The axis of the sleeve 14 is set in the vertical direction. The outer wall of the sleeve 14 is connected to the stamping plate 12 by a thread to adjust the connection position of the sleeve 14 and the stamping plate 12 in the vertical direction. The stamping block 13 is located between the two guide posts 15.

[0023] The compression spring 16 is sleeved on the guide post 15, and the sleeve 14 is sleeved and connected to the guide post 15 and located on top of the compression spring 16. The sleeve 14 is used to press the compression spring 16, and the compression spring 16 buffers the stamping plate 12. The stamping block 13 is fixedly installed on the stamping plate 12.

[0024] Guide pillars 15 are fixed on both sides of the base 11 and set vertically to provide stable vertical guidance for the stamping plate 12, ensuring accurate up-and-down movement of the stamping plate 12 during the stamping process, avoiding deviation, and ensuring stamping accuracy. The sleeve 14 is threadedly connected to the stamping plate 12 and can be adjusted in the vertical direction, making the height of the stamping plate 12 adjustable. It can be adjusted according to different sheet metal thicknesses and processing requirements, enhancing the adaptability of the mold. The compression spring 16 is sleeved on the guide pillar 15 and pressed by the sleeve 14, which plays a buffering role on the stamping plate 12, reducing the impact force during stamping, avoiding damage to the mold and sheet metal parts due to excessive impact, and extending the service life of the mold.

[0025] The first cylinder 21 and the second cylinder 22 are fixedly mounted on the bracket 17. The first cylinder 21 is located above the second cylinder 22 in the vertical direction. The output ends of the first cylinder 21 and the second cylinder 22 are both set in the horizontal direction.

[0026] The output end of the first cylinder 21 is connected to the first support block 31, and the output end of the second cylinder 22 is connected to the second support block 32. The side wall of the first support block 31 is provided with a rubber pad 33, and the maximum travel of the output end of the second cylinder 22 is greater than the maximum travel of the output end of the first cylinder 21.

[0027] The cross-sectional area of ​​the first support block 31 in the vertical direction is greater than the cross-sectional area of ​​the second support block 32 in the vertical direction.

[0028] A limiting block is provided at the front end of the second support block 32. The limiting block is used to limit the horizontal movement distance of the first support block 31 located above the second support block 32.

[0029] The first cylinder 21 and the second cylinder 22 provide lateral support through the support block, and the rubber pad 33 protects the sheet metal surface. Different stroke designs meet different sheet metal needs and improve support stability. After stamping, the output ends of the first and second cylinders are extended and retracted to push the support block to efficiently push out the sheet metal part. This method has a high degree of automation, precise operation, and can flexibly adjust the pushing force and distance, which can avoid human error and damage, and improve production efficiency and product quality.

[0030] The first cylinder 21 is fixed above the bracket 17, and its output end is horizontally connected to the first support block 31. It is mainly used to provide lateral support force for the sheet metal parts. During sheet metal stamping, the direction and magnitude of the stamping reaction force on sheet metal of different shapes and sizes are different. The first cylinder 21, in conjunction with the second cylinder 22, applies lateral force to stabilize the sheet metal and prevent it from swaying or shifting in the horizontal direction.

[0031] The horizontal positioning of the output end of the first cylinder 21 allows for precise contact with the side of the sheet metal. Combined with the sidewall rubber pad 33, this increases friction while preventing scratches on the sheet metal, ensuring stable support. The first support block 31, with its large cross-sectional area, provides ample contact with the sheet metal, distributing stress and making the support more stable.

[0032] The first cylinder 21 is linked with the second cylinder 22 below. The front limit block of the second support block 32 restricts the horizontal movement distance of the first support block 31. The two have different strokes but are closely matched to form a stable support system, which can adapt to various sheet metal stamping and improve the overall support stability.

[0033] The second cylinder 22 is mounted on the bracket 17, below the first cylinder 21. Its output end is connected to the second support block 32. It mainly provides diverse lateral support for sheet metal parts of different sizes and shapes. Due to the complex specifications of workpieces in sheet metal stamping, a single level of support stroke is difficult to adapt to all situations. The larger maximum stroke design of the second cylinder 22 allows it to flexibly adjust the support position and meet a wider range of sheet metal support needs.

[0034] The second cylinder 22 is arranged vertically in layers with the first cylinder 21. With the help of support blocks of different cross-sectional areas, it can provide targeted support from below for sheet metal of varying heights and widths. For example, when handling tall sheet metal, the second cylinder 22 can extend its stroke sufficiently to stabilize the bottom, prevent tipping, and enhance overall stability.

[0035] The second cylinder 22 and the second support block 32 have a limiting block at their front end, which precisely restricts the horizontal displacement of the first support block 31. The two work together to make the lateral support structure more compact and stable. Even when faced with complex and variable lateral forces during stamping, it can maintain a stable posture, ensure accurate positioning of the sheet metal, and greatly improve the reliability of the mold for supporting various sheet metal parts.

[0036] The larger stroke of the second cylinder 22 gives it greater versatility. Regardless of the thickness of the sheet metal parts, it can adjust the support distance as needed, complementing the first cylinder 21, improving the lateral support system, and reducing the risk of sheet metal swaying and displacement.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
