Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a continuous punching and forming mold for an automobile accessory bracket. Background Art

[0002] With the continuous improvement of the technological level of the automobile industry, the number of cars on the market has continued to increase, and high requirements have been put forward for the efficiency of automobile production and preparation. There is currently an auto parts bracket that is used to connect the vehicle chassis wheel hub with the suspension mechanism. It has high process requirements. As a sheet metal structure, it has many reinforced parts and high precision requirements for the connection positioning holes. Therefore, most manufacturers use punching dies for production and forming. However, there are various types of punching dies used traditionally. In order to meet the molding precision control of multiple structures, most factories use multiple combination dies to cooperate in punching production. This leads to a large number of conversions between multiple dies to position the punching blanks. After multiple positioning, not only the accuracy cannot be guaranteed, but also the workload of the staff is increased invisibly, and the work efficiency is low. At the same time, the traditional continuous punching forming mold is not easy to disassemble, it is not easy to cut the blade and module, and the practical performance is low.

[0003] The patent name is "CN219378700U", which is a continuous punching and forming die for an automobile parts bracket. The public document solves the above problems, but the device in the public document does not have a function for positioning the workpiece, which results in the stamping part of the stamped part not being able to accurately overlap with the stamping cutting blade in the public document, thereby causing a large stamping error of the stamped part, which not only affects the processing effect of the stamped part, but also causes the occurrence of the scrapping of the stamped part. Based on this, the utility model designs a continuous punching and forming die for an automobile parts bracket to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example 1

[0026] like Figure 1 , Figure 2 , Figure 4 , Figure 5As shown, the device includes a base plate 1 and a guide column 2, the guide column 2 is fixed at the four corners of the top of the base plate 1, a limiting component 3 is arranged at the middle end of the top of the base plate 1, and a stamping component 4 is sleeved on the outer upper end of the guide column 2. The limiting component 3 includes a mounting seat 301 fixed at the middle end of the top of the base plate 1, a V-shaped groove 302 is integrally arranged at the middle end of the inner part of the mounting seat 301, support rods 303 are fixed on the left and right sides of the rear end of the top of the mounting seat 301, and a limiting groove 304 is integrally arranged on the inner side of the support rod 303, and the stamping component 4 includes a support plate 401 slidably sleeved on the outer upper end of the guide column 2, a stamping block 402 is fixed at the middle end of the bottom of the support plate 401, and the stamping plates 403 arranged on the left and right sides of the stamping block 402 are fixedly connected to the support plate 401.

[0027] First, the staff connects the middle end of the top of the support plate 401 to the head end of the existing stamping equipment, and then places the workpiece on the top of the mounting seat 301, and inserts the right-angle areas on the left and right sides of the rear end of the workpiece into the limit groove 304 inside the support rod 303, so as to position the workpiece. At this time, the stamping area of ​​the workpiece is in a state of overlap with the V-groove 302 and the stamping block 402. The staff then uses the stamping equipment to make the stamping equipment drive the support plate 401 and the stamping block 402 to move along the direction of the V-groove 302, that is, the support plate 401 moves downward along the longitudinal direction of the guide column 2. At this time, the stamping area of ​​the workpiece squeezed by the stamping block 402 moves into the V-groove 302, so as to bend the workpiece. In addition, the support plate 401 drives the stamping plate 403 to flatten the left and right sides of the bent workpiece. In the above manner, the workpiece is always in a state of positioning during the stamping process, so as to avoid the phenomenon of large errors in the stamping area of ​​the workpiece, that is, to ensure the stamping effect of the workpiece.

[0028] Example 2

[0029] like Figure 2 , Figure 3 As shown, the front cross section of the stamping block 402 is V-shaped, and the stamping block 402 and the V-shaped groove 302 are in a mutually overlapping design. The left and right sides of the support plate 401 are integrally provided with a clearance hole 5, and the clearance hole 5 is a through hole design. A stamping rod 6 is fixed at the middle end of the bottom of the stamping plate 403, and the bottom surface of the stamping rod 6 is higher than the bottom surface of the stamping block 402. The two stamping rods are in a longitudinally parallel design, and the bottom surfaces of the two stamping rods are in a flush state, and the mounting seat 3 01 A punching hole 7 is integrally provided on the left and right sides of the top of the interior. The punching hole 7 is a blind hole design. The punching hole 7 and the punching rod 6 are in a one-to-one design, and the diameter of the punching hole 7 is larger than the diameter of the punching rod 6. A spring 8 is fixed at the lower end of the inside of the punching hole 7. A slider 9 fixed on the top of the spring 8 is slidably connected to the punching hole 7. The clearance hole 5 and the support rod 303 are in a one-to-one design, and the diameter of the clearance hole 5 is larger than the size of the cross-section of the support rod 303 when viewed from above.

[0030] According to the operation method in Example 1, when the punching block 402 is about to complete the bending and punching of the workpiece, the support plate 401 drives the punching plate 403 together with the punching rod 6 to punch the left and right sides of the workpiece, that is, the punching rod 6 moves into the punching hole 7. At this time, the punching rod 6 punches the workpiece. At the same time, the punching rod 6 drives the waste material after the workpiece is punched to exert an extrusion force on the slider 9, so that the slider 9 squeezes the spring 8 to deform. When the punching of the workpiece is completed and the bending and punching of the workpiece are completed at the same time, the punching device 401 is pressed. The support plate 401 together with the punching block 402, the punching plate 403 and the punching rod 6 are reset. At this time, the slider 9 pushes the waste left after the workpiece is punched to be discharged from the inside of the punching hole 7 through the rebound force of the spring 8. The staff can then take out the bent and punched workpiece and the waste from the mounting seat 301. The clearance hole 5 makes room for the support plate 401 to pass through the support rod 303, ensuring the stable effect of the support plate 401 moving longitudinally along the guide column 2.
