[0034] Stamping is a forming process that uses a punch press and a die to deform or break hardware materials such as stainless steel, iron, aluminum, and copper. The principle of stamping is that the pressure generated by the punch press causes the die to apply external force to the material, thereby achieving deformation and separation of the material. In related technologies, stamping forming usually uses a separate cutting device to cut the hardware sheets, and then transports the cut single sheets to a bending device, which then performs stamping and bending on the single sheets. This processing method requires cumbersome storage and transfer operations of the materials, resulting in low processing efficiency. In addition, the cumbersome handling and transfer operations are prone to inaccurate alignment problems, resulting in insufficient processing precision in stamping forming.

[0035] In order to solve this problem, some equipment that attempts to integrate the punching and bending processes into one has appeared on the market, but these devices are often complex in structure, cumbersome to operate, and lack effective control over the positioning and transportation of hardware sheets, resulting in processing quality and efficiency still needing to be improved. Specifically, during the transportation of hardware sheets, existing equipment is prone to sheet position offset or unstable transportation, resulting in reduced punching and bending accuracy. At the same time, when used in conjunction with existing punching and bending devices, manual adjustment of the sheet position is often required, which not only increases labor intensity but also reduces production efficiency. In addition, during the bending process, existing equipment lacks an effective pre-stressing and elastic adjustment mechanism, which can easily lead to inaccurate bending angles and even damage the hardware sheets.

[0036] The following reference Figure 1 To the attached Figure 5 , describing the continuous stamping and forming device of the embodiment of the utility model, which can bend and punch metal sheets, and the processing is continuous, the production efficiency is high, and the stamping accuracy is high.

[0037] Reference Figures 1 to 5 , a continuous stamping forming device according to an embodiment of the present utility model comprises:

[0038] The frame 100 is provided with a working platform 110, and the working platform 110 is provided with a punching station and a bending station arranged in sequence along the advancing direction of the metal sheet. The punching station and the bending station are adjacent to each other. The punching station is provided with a punching die hole 120 and two mutually parallel first limiting strips 130. The bottom of each first limiting strip 130 is provided with a first limiting groove 131. The two first limiting grooves 131 are arranged oppositely. The bending station is provided with a bending die cavity 140 and two mutually parallel The second limiting strips 150 are provided with a second limiting groove 151 at the bottom of each second limiting strip 150. The two second limiting grooves 151 are arranged opposite to each other. The two second limiting strips 150 are coaxial with the two first limiting strips 130 respectively, that is, each second limiting strip 150 is located on the extension line of the corresponding first limiting strip 130, and each first limiting strip 130 and the corresponding second limiting strip 150 are respectively connected to the opposite sides of the punching die hole 120, that is, the end of the first limiting strip 130 is connected to One side of the top opening of the punching die hole 120, the end of the second limiting strip 150 is connected to the other side of the top opening of the punching die hole 120, which can effectively shorten the distance between the first limiting groove 131 and the second limiting groove 151, and can effectively improve the reliability of the continuous feeding action. The projection of the first limiting groove 131 on the second limiting strip 150 overlaps with the second limiting groove 151, so that the hardware piece can smoothly enter the second limiting groove 151 from the first limiting groove 131. The first limiting groove 131 and the two second limiting grooves 151 form a limiting material channel for limiting the edge position of the metal sheet, which can effectively limit the metal sheet from moving along the specified trajectory. The bending die cavity 140 is located on the side of the second limiting strip 150 away from the punching die hole 120. The bending die cavity 140 is located at the edge of the working platform 110 and passes through the side of the working platform 110 to ensure that the bent metal sheet can be smoothly output from the side of the bending die cavity 140.

[0039] The leveling assembly 200 includes a leveling drive mechanism 210 and a leveling roller assembly 220. The leveling drive mechanism 210 is connected to the frame 100, and the leveling roller assembly 220 is connected to the leveling drive mechanism 210. The leveling roller assembly 220 is located on the side of the punching station away from the bending station. The leveling assembly 200 is located outside the work platform 110. The leveling roller assembly 220 is used to level and drive the metal sheet forward. The driving and feeding direction of the leveling assembly 200 is parallel to the first limiting bar 130 and the second limiting bar 150.

[0040] The punching assembly 300 is located directly above the punching station and includes a punching drive mechanism 310 and a knife holder 320. The punching drive mechanism 310 is connected to the frame 100, and the knife holder 320 is connected to the driving end of the punching drive mechanism 310. The punching drive mechanism 310 is used to drive the knife holder 320 to rise and fall relative to the work platform 110. A punching knife 321 that matches the punching die hole 120 is mounted below the knife holder 320. The punching knife 321 is used to cooperate with the punching die hole 120 to generate a shear force on the metal sheet, thereby punching and cutting the metal sheet.

[0041] The bending assembly 400 is located just above the bending station. The bending assembly 400 includes a bending drive mechanism 410, a bending push plate 420, an elastic connection mechanism 430 and a pre-pressing plate 440. The bending drive mechanism 410 is connected to the frame 100, and the bending push plate 420 is connected to the driving end of the bending drive mechanism 410. The bending drive mechanism 410 is used to drive the bending push plate 420 to rise and fall relative to the working platform 110. The pre-pressing plate 440 is connected to the bending drive mechanism 410 through the elastic connection mechanism 430. The bottom of the bending push plate 420, that is, the pre-stressing plate 440 is located below the bending push plate 420, and the elastic connection mechanism 430 connects the pre-stressing plate 440 and the bending push plate 420 respectively. The elastic connection mechanism 430 is used to make the pre-stressing plate 440 form a movement trend away from the bending push plate 420. The bottom of the bending push plate 420 is provided with a bending convex module 421 matching the bending concave mold cavity 140. The bending convex module 421 is used to cooperate with the bending concave mold cavity 140 to bend the hardware sheet.

[0042] The working process is as follows: the metal sheet is flattened after passing through the flattening assembly 200 and is conveyed between the two first limiting strips 130. Under the limiting action of the two first limiting grooves 131, the metal sheet passes through the punching die hole 120, then enters the two second limiting grooves 151, and finally reaches the bending die cavity 140; the bending drive mechanism 410 drives the bending push plate 420 to descend, and the pre-pressing plate 440 presses the metal sheet on the bending station. As the bending push plate 420 continues to descend, the elastic connection mechanism 430 is continuously compressed and the bending convex module 421 continues to descend, and the bending convex module 421 presses the head of the metal sheet into the bending die cavity 140, thereby realizing bending and forming the head of the metal sheet; the punching drive mechanism 310 drives the knife holder 320 to descend, and the punching knife 321 cuts into the surface of the metal sheet, and then punches The cutter 321 enters the punching die hole 120 to cut the metal sheet, thereby obtaining a metal sheet that has completed the stamping forming process; then the bending drive mechanism 410 drives the bending push plate 420 to rise, the bending convex module 421 and the pre-pressing plate 440 release the metal sheet, and the punching drive mechanism 310 drives the knife holder 320 to rise to make the punching knife 321 separate from the metal sheet, and the leveling component 200 continues to level the metal sheet to be processed and convey it forward. The metal sheet to be processed passes above the punching die hole 120 and enters between the two second limiting grooves 151, thereby pushing the completed metal sheet forward. When the metal sheet to be processed reaches above the bending die cavity 140, the completed metal sheet is completely pushed away from the working platform 110, providing reliable material feeding and unloading for continuous processing.

[0043] The bending assembly 400 and the punching assembly 300 can be used to bend and punch the metal sheet, which has high processing efficiency and can effectively save the space required for processing. The device occupies a small area, thereby saving land costs and reducing processing costs. The elastic connection mechanism 430 cooperates with the pre-pressing plate 440 to press and position the metal sheet, which can provide a stable processing foundation for the punching and bending of the bending convex module 421 and the punching and cutting of the punching knife 321. The punching and forming precision is high and the punching and forming action is continuous and reliable.

[0044] The leveling component 200 can not only level the metal sheets, thereby effectively improving the accuracy of subsequent processing, but also provide a good processing foundation for stamping and forming, and avoid affecting the processing quality due to the unevenness of the metal sheets, but also the leveling component 200 can realize continuous transportation of the metal sheets, and can continuously feed the subsequent punching and forming processing, which can effectively improve production efficiency. In addition, the first limiting groove 131 and the second limiting groove 151 located on the same straight line can form a reliable guiding effect for the metal sheets, which can improve the accuracy of bending and punching processing. After the metal sheets are cut by the punching knife 321 in conjunction with the punching die hole 120, the metal sheets to be processed can be effectively pushed forward by the guidance of the first limiting groove 131 and the second limiting groove 151. The continuous feeding effect is reliable, and reliable and continuous stamping and forming processing can be realized with high production efficiency. There is no need for workers to directly operate and intervene in the hardware sheets, which can not only effectively improve production efficiency but also effectively improve processing safety.
