Description

Technical Field

[0001] This utility model relates to the field of thin plate forming technology, and more specifically, to a continuous mold for preventing deformation of thin plate materials. Background Technology

[0002] Sheet materials (typically 0.1-3.0 mm thick) encompass both metallic (such as cold-rolled steel sheets and aluminum foil) and non-metallic (such as plastic sheets and cardboard) materials, and are widely used basic materials in industrial production. However, its inherent low stiffness and low strength make it extremely susceptible to deformation such as bending, warping, and wrinkling due to external forces (stamping, shearing, etc.) during processing. Especially in the multi-process integrated processing of progressive dies, thin plates need to be subjected to external forces repeatedly, which can easily lead to cumulative deformation. Conventional dies lack effective force constraints and buffer structures, and cannot specifically solve the above problems, ultimately resulting in product size deviations and irregular shapes, which seriously affect processing accuracy and production efficiency.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] This embodiment discloses a progressive die for preventing deformation of thin sheet materials, which aims to solve the problems in the prior art where thin sheet materials have low stiffness and are easily deformed, and conventional progressive dies cannot effectively constrain the force on the material, resulting in product size deviations and irregular shapes. It realizes anti-deformation control and multi-process integrated processing in the thin sheet processing process, thereby improving product accuracy and production efficiency.

[0015] Specifically, as shown in the attached document Figure 1 Appendix Figure 2 As shown, the anti-deformation progressive mold for thin sheet materials includes a base 1, which provides stable support for the overall structure. A template 2 is detachably connected to its top via bolts, facilitating the disassembly, maintenance, and replacement of the template 2. (See attached image.) Figure 1 Appendix Figure 5 As shown, a positioning and forming component is provided at the top of template 2; The positioning and forming assembly includes a pressure plate 3, a buffer plate 4, a forming plate 5, and several springs 6. The pressure plate 3, buffer plate 4, and forming plate 5 are stacked from top to bottom. The buffer plate 4 is fixed to the bottom of the pressure plate 3 by bolts. The springs 6 are evenly distributed between the buffer plate 4 and the forming plate 5, with their ends abutting against the bottom of the buffer plate 4 and the top of the forming plate 5, respectively. (See attached image) Figure 5 As shown, two hydraulic rods 11 are symmetrically arranged on the top of the template 2. The output end of each hydraulic rod 11 extends vertically upward to the bottom of the pressure plate 3 to provide a stable downward driving force for the pressure plate 3.

[0016] As attached Figure 1 Appendix Figure 4 As shown, a spacer plate 7 and a forming block 8 are bolted to one end of the template 2. The spacer plate 7 and the forming block 8 are arranged adjacent to each other. A through-hole cavity 9 is opened on the spacer plate 7 to realize the blanking process of the sheet metal. A bending forming surface is provided on one side of the forming block 8 to realize the bending process of the sheet metal. The two work together to realize the integrated processing requirements of blanking and bending. See attached... Figure 1 Appendix Figure 3 As shown, a feeding ramp 10 is provided at the end of the template 2 away from the pad plate 7. The top of the feeding ramp 10 is flush with the top of the template 2, and the bottom extends downward to one side of the base 1, so that the workpiece can be automatically dropped after processing.

[0017] As attached Figure 1 Appendix Figure 2 As shown, two parallel sliding grooves are provided in the middle of the base 1, and a slag collection box 12 is slidably connected in each sliding groove. The two slag collection boxes 12 are located directly below the bottom of the punching cavity 9 and the forming block 8, respectively, and are used to accurately receive the waste generated by the sheet metal punching process and the debris that falls off during the bending process. The slag collection box 12 can be pulled out along the sliding groove for convenient collection and cleaning of waste.

[0018] The specific working principle is as follows: Place the sheet material to be processed with a thickness of 0.1-3.0mm, such as cold-rolled steel plate, aluminum foil or plastic sheet, on the top of the template 2, so that the processing area of ​​the sheet corresponds to the punching cavity 9 of the pad plate 7 and the bending forming surface of the forming block 8, and complete the initial positioning of the sheet.

[0019] Start the hydraulic rod 11. The output end of the hydraulic rod 11 extends upward, pushing the pressure plate 3, buffer plate 4 and forming plate 5 downward as a whole until the bottom of the forming plate 5 is in contact with the surface of the thin plate material. Continue to apply pressure. The spring 6 is squeezed by the buffer plate 4 and undergoes elastic deformation, generating uniform elastic pressure that acts on the forming plate 5. The pressure is transmitted to the thin plate material through the forming plate 5, realizing flexible pressing and positioning of the thin plate. The buffering and energy absorption effect of the spring 6 can offset the impact force generated during processing and prevent the thin plate from deforming due to excessive local stress.

[0020] While the forming plate 5 is kept in a pressed state, the thin plate is punched through the punching cavity 9. The waste generated by punching falls directly into the corresponding slag box 12 below. After punching, the thin plate is pushed to the forming block 8 by the conveying mechanism. The forming block 8 is used to bend the thin plate. During the bending process, the forming plate 5 continuously presses the thin plate to prevent it from warping, wrinkling and deforming.

[0021] After processing, the workpiece is moved to the unloading ramp 10 by the conveying mechanism and automatically slides down the inclined surface of the unloading ramp 10 into the collection device. The waste collected during processing can be cleaned by pulling out the slag box 12. After cleaning, the slag box 12 can be pushed back to the original position of the chute for the next batch of processing.

[0022] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
