Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, specifically to a bending and stamping fixture. Background Technology

[0002] Stamping dies are molds that use the pressure of a bending machine to process metal or non-metal sheets into workpieces of specific shapes and sizes. During processing, the material is deformed or cut into the die by the punch inside the die, and the cavity is formed by the cooperation of the die and the punch. With the help of guiding and positioning components, the flat blank is transformed into various structural parts such as shells, brackets, and gaskets.

[0003] However, stamping dies are production molds that require a one-time investment. Their cost must be spread across each molded product. When the order volume is sufficient, the mold cost per unit will be significantly reduced. But when the order volume is very small and the logo molding area is large, the limited number of products cannot absorb the high mold investment, which will eventually lead to the mold cost per unit being too high, even exceeding the material and processing costs of the product itself.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0020] like Figures 1-12 As shown, in one embodiment, a bending stamping fixture includes: a first fixture 1 and a second fixture 2; The first tooling 1 is installed on the top of the bending machine and is used to apply directional stamping force to the product under the drive of the equipment, so as to finally realize the LOGO forming and edge bending of the sheet material. For example, the first tooling 1 includes a first connecting portion 11, on which a first stamping portion 12 is mounted. The first stamping portion 12 is detachably connected to the bending machine via the first connecting portion 11, such that the first stamping portion 12 has a first direction ( Figure 1 The stamping path (moving along the Y-axis direction); It should be explained in detail that the first connecting part 11 is formed by welding multiple sets of flat plates side by side. This not only ensures the overall structural rigidity of the connecting part and can withstand the instantaneous impact force during stamping without deformation, but also allows for the adjustment of the number of steel plates to accommodate different sizes of the first stamping part 12, thereby improving the versatility of the tooling. Specifically, the first connecting part 11 has a first snap-fit ​​groove 111, and the first connecting part 11 is detachably connected to the top of the bending machine through the first snap-fit ​​groove 111.

[0021] Understandably, the dimensions of the first snap-fit ​​groove 111 are perfectly matched with the slide groove of the upper die on the top of the bending machine. Through snap-fit, the first tooling 1 can be quickly positioned and installed without repeated calibration, which greatly improves the assembly efficiency of the tooling.

[0022] Furthermore, the bottom of the first connecting part 11 is provided with a first mounting hole 112, and the first connecting part 11 is detachably connected to the first stamping part 12 through the first mounting hole 112; correspondingly, the first stamping part 12 is provided with a second mounting hole 121, and the first stamping part 12 is detachably connected to the first connecting part 11 through the second mounting hole 121.

[0023] Understandably, during actual assembly, high-strength bolts can be inserted into the two sets of mounting holes for fastening. This connection method is not only convenient to disassemble, but also ensures that there is no relative displacement between the two during the stamping process, thus ensuring the stable transmission of stamping force.

[0024] Please continue reading. Figures 1-12 In this embodiment, the second tooling 2 is installed at the bottom of the bending machine to provide stable support and positioning for the sheet metal to be processed. It works in conjunction with the back gauge positioning of the bending machine to prevent the sheet metal from warping and shifting under the stamping force, thereby ensuring the dimensional accuracy of the LOGO forming. For example, the second tooling 2 includes a second connecting part 21, on which a second stamping part 22 is mounted, and the second stamping part 22 is detachably connected to the bending machine through the second connecting part 21.

[0025] It should be explained in detail that the second connecting part 21 is formed by welding multiple sets of flat plates side by side. This not only ensures the overall structural rigidity of the connecting part and can withstand the instantaneous impact force during stamping without deformation, but also allows for the adaptation of the number of steel plates to accommodate second stamping parts 22 of different sizes, thereby improving the versatility of the tooling. Specifically, the second connecting part 21 has a second snap-fit ​​groove 211, and the second connecting part 21 is detachably connected to the bottom of the bending machine through the second snap-fit ​​groove 211.

[0026] Understandably, the dimensions of the second snap-fit ​​groove 211 are perfectly matched with the slide groove of the lower die on the top of the bending machine. Through snap-fit, the second tooling 2 can be quickly positioned and installed without repeated calibration, which greatly improves the assembly efficiency of the tooling.

[0027] Furthermore, the bottom of the second connecting part 21 is provided with a third mounting hole 212, and the second stamping part 22 is detachably connected to the second connecting part 21 through the third mounting hole 212; correspondingly, the second stamping part 22 is provided with a fourth mounting hole 221, and the second stamping part 22 is detachably connected to the second connecting part 21 through the fourth mounting hole 221.

[0028] Understandably, during actual assembly, high-strength bolts can be inserted into the two sets of mounting holes for fastening. This connection method is not only convenient to disassemble, but also ensures that there is no relative displacement between the two during the stamping process, thus ensuring the stable transmission of stamping force.

[0029] In some embodiments, the outer contour of the first stamping part 12 fits into the inner contour of the second stamping part 22, thereby enclosing and forming the text and graphic outline of the target logo; while the flat cold-rolled plate 3 is placed between the first stamping part 12 and the second stamping part 22, which has good cold plasticity, is suitable for concave forming and is not easy to spring back after forming.

[0030] Specifically, the height difference between the outer contour of the first stamping part 12 and the inner contour of the second stamping part 22 is 0.4-0.6mm, which can reserve space for the stamping deformation of the sheet metal, while ensuring that the depth of the LOGO after stamping is stable at 0.5mm. This avoids the sheet metal from being unable to deform sufficiently due to too small a height difference, and also prevents the LOGO from exceeding the depth limit or the sheet metal from cracking due to too large a height difference.

[0031] Working principle: Tooling and sheet clamping: First, the first tooling 1 is inserted into the upper die slide of the bending machine through its first snap-fit ​​groove 111, ensuring that it is snapped in place and fixed; at the same time, the second tooling 2 is inserted into the lower die slide through its second snap-fit ​​groove 211, and the coaxiality of the upper and lower dies is calibrated after completion; then, the 1.5mm thick flat cold-rolled sheet 3 is placed stably between the first stamping part 12 and the second stamping part 22, ensuring that the edge of the sheet is aligned with the positioning reference of the lower die to prevent positional deviation in subsequent stamping; Stamping parameter setting and execution: Start the bending machine and call the preset bending program. The program needs to preset the stamping pressure, pressing speed and stroke according to the size and depth of the LOGO. The plate is positioned twice by the positioning system of the equipment. After confirming that the plate position is correct, the bending machine is controlled to drive the first tooling 1 of the upper die to move downward in the vertical direction. During the stamping process, the first stamping part 12 of the first tooling 1 acts on the surface of the flat cold-rolled plate 3 at a uniform speed. Under the pressure of the first stamping part 12 and the support of the second stamping part 22, the plate is deformed along the inner contour of the second stamping part 22, and finally forms a LOGO with a depth of 0.5mm. Welding treatment of sheet material edges: After the logo is formed, weld one edge of the sheet material. The welding method can be spot welding or seam welding according to product requirements. After one side is welded and cooled to room temperature, weld the other edge of the sheet material in sequence according to the same welding process and parameters. This avoids the sheet material from warping due to welding stress concentration caused by welding both sides at the same time, and ensures the overall flatness and dimensional accuracy of the product.

[0032] Through the above technical solution, this application produces a connecting part by cutting ordinary flat plates, splicing them side by side according to size requirements, welding and reinforcing them, and then finely grinding them. It is then combined with customized punches and dies in a modular manner to form a complete forming tooling. Through the pre-set snap-fit ​​grooves and mounting holes of the connecting part, it can be quickly and accurately installed into the upper and lower die systems of a conventional bending machine. This effectively reduces the cost of mold opening while realizing the stamping and bending forming of products, and does not require modification of existing equipment, greatly improving the equipment adaptability and tooling assembly and disassembly efficiency.

[0033] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
