For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0032] The following further explains and illustrates the present utility model in combination with specific implementation manners.
[0033] As Figure 1-7As shown in the figure, a blanking die for new energy vehicle parts provided in this embodiment includes an upper die assembly 1, and the upper die assembly 1 is vertically adapted to the lower die base 3 for blanking sheet metal. On both sides of the upper surface of the lower die base 3, a quick clamp 4 and a positioning assembly 5 are respectively installed for fixing the sheet metal. The quick clamp and the positioning assembly are used in combination, with stronger applicability, and can be used for blanking processing of special-shaped parts with dimensional requirements. The positioning assembly 5 further includes a positioning plate 51. Both ends of the body of the positioning plate 51 abut and fit against both side walls of the body of the lower die base 3. On both side walls of the body of the lower die base 3, horizontal scales a31 are respectively provided. Below the scales a31, a chute 32 is provided, and the chute 32 is adapted to the sliding of the convex slider 511 for positioning the sheet metal. The scale a on the lower die base and the scale b on the positioning plate replace the cross scale lines to assist in positioning. The scales a and b will not be blocked by the size of the product itself, the powder or dust remaining in the blanking process, and are easy to read, ensuring the precise positioning of the sheet metal to be processed. The precise positioning of the positioning assembly ensures the accuracy of the workpiece during the blanking process, reducing errors and the rejection rate.
[0034] As Figure 1 , Figure 6 , Figure 7 As shown in the figure, in this embodiment, convex sliders 511 are symmetrically arranged at both ends of the lower surface of the body of the positioning plate 51. The 32 convex sliders are adapted to the chutes, enabling the positioning plate to slide along the direction of the scale a on the lower die base for positioning the sheet metal. At the bottom of one side wall of the positioning plate 51, a vertical scale b512 is provided. The scale a is used for the horizontal positioning of the sheet metal, and the scale b is used for the vertical positioning of the sheet metal. In the middle of the other side wall of the positioning plate 51, a circular groove 513 is provided, and a bearing 52 is installed inlaid in the groove 513. Through the bearing, the rotational motion of the screw rod becomes the linear motion of the positioning plate. The bearing 52 is sleeved on one end of the screw rod 53, and a spiral handle 54 is provided at the other end of the screw rod 53. The rotation of the spiral handle 54 drives the sliding of the positioning plate 51. The inner wall of the body of the spiral support 55 is provided with internal threads, the outer wall of the body of the screw rod 53 is provided with external threads, and the screw rod 53 is appropriately sleeved in the spiral support 55. The spiral support 55 is fixed on the upper surface of the lower die base 3. Rotating the spiral handle, the external thread part of the screw rod will move in the internal thread of the spiral support, causing the screw rod to move forward or backward along the direction of the scale a. When tightened, the screw rod will move forward, causing the positioning plate to move forward along the direction of the scale a close to the punching hole; when loosened, the screw rod will move backward, causing the positioning plate to move backward along the direction of the scale a away from the punching hole. The position of the positioning plate can be adjusted to adapt to workpieces of different sizes. Due to the design of the screw rod and the spiral support, when the screw rod rotates, it drives the positioning plate to move precisely relative to the scale a, thereby realizing the precise positioning of the workpiece. When processing the same type of sheet metal, only one horizontal dimension positioning is required, optimizing the blanking process. Compared with using cross scale lines to assist in positioning, more precise positioning is achieved, improving the processing accuracy and production efficiency.
[0035] As Figure 1 , Figure 4, Figure 5 As shown, in this embodiment, the quick clamp 4 further includes a base 41 fixed to the lower die base 3. At both ends of the upper part of the base 41 body, a connecting rod a 42 and a connecting rod b 43 are respectively hinged. The ends of the connecting rod a 42 and the connecting rod b 43 are respectively hinged to both ends of the connecting rod 44. The connecting rod 44 is provided with a handle 45 extending obliquely at one end on the side of the connecting rod b 43. When the handle is pressed down, the connecting rod moves towards the punching direction, driving the connecting rod a and the connecting rod b to rotate towards the punching direction until the connecting rod a is perpendicular to the lower die base, the connecting rod b and the connecting rod are collinear, and the connecting rod moves to the limit position, which can provide a stable pressing force for the plate to be processed, and the quick clamp presses the plate to be processed; when the handle is lifted, the connecting rod moves away from the punching direction, driving the connecting rod a and the connecting rod b to rotate in the opposite direction, and the quick clamp opens to release the processed workpiece. Only by controlling the handle can the clamping and releasing of the plate be completed. Compared with the traditional manual adjustment and fastening of the workpiece by rotating the bolts and nuts on the clamp, the clamping and unloading time of the workpiece is shortened, and the production efficiency is improved. An adjusting long hole 421 is extended at the front part of the connecting rod a 42 body, and the clamping bolt 46 is sleeved in the adjusting long hole 421. The clamping bolt can slide in the adjusting long hole to adjust the position of the pressing block so as to adapt to plates of different sizes. The clamping bolt 46 passes through both ends of the adjusting long hole 421 and is adaptively installed with a gasket 47 and a fastening nut 48. The gasket and the fastening nut work together to fix the clamping bolt in the adjusting long hole. By rotating the two fastening nuts, the relative position of the clamping bolt in the adjusting long hole can be adjusted, so as to change the distance between the pressing block and the punching hole and the height of the pressing block from the lower die base, so that the quick clamp can clamp the blanking plates of different sizes and different thicknesses. A pressing block 49 is provided at the bottom of the clamping bolt 46. The pressing block can bear a large pressure and clamping force and is used to press the plate during the blanking process. A number of quick clamps are fixed on one side of the lower die base. These quick clamps are used to quickly fix or release the processed plate, shorten the clamping and unloading time of the workpiece, improve the production efficiency, and the quick clamp can accurately fix the workpiece at a predetermined position to ensure the accuracy and consistency during the processing. The quick clamp and the positioning component are used in combination, with stronger applicability, and can be used for the blanking processing of special-shaped parts with size requirements. During the blanking processing, one side of the special-shaped part abuts against the positioning plate, and the other side is fixed at the corresponding position by a number of quick clamps with adjustable positions. The combined use of the quick clamp and the positioning component replaces the traditional method of putting the workpiece into a specific clamp and then manually adjusting and fastening the workpiece by the bolts and nuts on the clamp, improves the production efficiency, and reduces the production cost.
[0036] As Figure 1-3As shown in the figure, in this embodiment, the upper die assembly 1 further includes a top plate 11. A pneumatic press 12 is installed through the middle of the top plate 11, and a punch 13 is installed at the bottom of the pneumatic press 12. The pneumatic press is an existing product and is the power source in the blanking die. It generates power through compressed air and drives the punch to perform stamping operations. The punch is made of wear-resistant materials to withstand repeated stamping and wear. The shape and size of the punch are designed according to the shape and size of the workpiece to be processed, and the punching shape fits the shape of the punch. A through punching hole 33 is provided in the middle of the upper surface of the lower die base 3, and the punching hole 33 fits the punch 13. The blanking falls through the punching hole. The lower surface of the top plate 11 is connected to the upper surface of the lower die base 3 through a number of fixed columns 2. The fixed columns are used to connect the top plate and the lower die base together to ensure that the top plate and the lower die base maintain the correct relative position during the stamping process. A fixed bracket 6 is fixed to the lower surface of the lower die base 3. The bracket is used to fix and support the lower die base. During the blanking process, the bracket also undertakes the task of guiding the smooth falling of the blanking, avoiding material accumulation or blockage, and ensuring the smooth progress of the entire blanking process.
[0037] The working principle of the technical solution provided by the present utility model is as follows:
[0038] During the first blanking of the same type of plate, first determine the specific dimensions of the position of the plate to be blanked. Then rotate the spiral handle, move the positioning plate, and observe the position of the positioning plate on the scale a until the position of the side wall where the scale b of the positioning plate is located on the scale a is the lateral dimension of the position of the plate to be blanked; place the plate on the lower die base, with the side of the plate abutted against the side wall where the scale b of the positioning plate is located, and move the plate along the direction of the scale b until the position of the plate on the scale b is the longitudinal dimension of the position of the plate to be blanked, thus completing the positioning of the plate. After that, by rotating two fastening nuts, adjust the relative position of the clamping bolt in the adjusting long hole, thereby changing the distance between the pressing block and the punching hole, and the height of the pressing block from the lower die base, so that the pressing block can act on the plate and press the plate; press one end of the plate tightly against the positioning plate, and press the handle of the quick clamp at the other end of the plate, and the quick clamp presses the plate to be processed, thus completing the positioning of the plate. Finally, start the pneumatic press to complete the blanking process of the plate. After the blanking of the plate is completed, lift the handle and take out the blanked plate.
[0039] When processing the same type of plate, only one lateral dimension positioning and adjustment of the position of the clamping bolt in the quick clamp are required. After that, place the plate on the lower die base, with one end abutted against the side wall of the positioning plate and the other end pressing the handle of the quick clamp to clamp the plate to be processed. This optimizes the blanking process. Compared with the cross scale line to assist positioning, it achieves more accurate positioning, improves the processing accuracy and production efficiency.
[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
