[0002] A progressive die, also known as a progressive die or a step-by-step die, is a cold stamping die that uses strip stamping raw materials to complete multiple stamping processes simultaneously on a die through several different stations in one stamping stroke of a press. In a continuous die, the blanking parts are gradually formed, including trimming, notching, grooving, punching, plastic deformation, blanking and other processes can be completed on a die. The design of this die takes into account the feeding method, positioning and stamping content of the stamping. By reasonably arranging multiple stamping processes for continuous stamping, the continuous die can not only complete the blanking process, but also the forming process and even the assembly process.

[0003] The above prior art often has the following problems when used:

[0004] When the existing continuous die for processing the left mounting bracket of the front suspension of an automobile is in use, when continuously stamping the strip raw material, additional power is needed for stamping and feeding. The two cooperate with each other. After the upper die is stamped and reset, the feeding mechanism runs again to feed the material. The cost of use will become high, and the coordination and debugging operation between the two is also cumbersome. Utility Model Content

[0023] The stepper assembly includes a slide rail 11 fixedly connected to the upper surface of the base 1, a guide plate 12 is slidably connected in the slide rail 11, a plurality of semicircular grooves 13 and vertical grooves 14 are equidistantly provided on the surface of the guide plate 12, a second rotating shaft 15 is rotatably connected to the front of the mounting plate 7 through a bearing, a rotating plate 16 is fixedly connected to the end of the second rotating shaft 15 away from the mounting plate 7, an arc-shaped abutment plate 17 and a rotating rod 18 are fixedly connected to the surface of the rotating plate 16, a driving wheel 19 is fixedly connected to the circumference of the first rotating shaft 8, a driven wheel 20 is fixedly connected to the circumference of the second rotating shaft 15, the driving wheel 19 and the driven wheel 20 are connected by a belt drive, and the guide plate 12 is connected to the front of the mounting plate 7 through a bearing. A fixed plate 21 is fixedly connected to the surface, a No. 1 clamping plate 22 is fixedly connected to the side wall of the fixed plate 21, a No. 2 clamping plate 23 is arranged above the No. 1 clamping plate 22, and two guide rods 24 are fixedly connected to the bottom surface of the No. 1 clamping plate 23, and the two guide rods 24 are both slidably connected to the bottom surface of the No. 1 clamping plate 22, and the bottom ends of the two guide rods 24 are fixedly connected to the limiting plate 25, and the two guide rods 24 are both sleeved with springs, and multiple semicircular grooves 13 and vertical grooves 14 are respectively arranged adjacent to each other at intervals, the arc-shaped abutment plate 17 cooperates with the semicircular groove 13, the rotating rod 18 cooperates with the vertical groove 14, and the two springs are arranged between the No. 1 clamping plate 22 and the limiting plate 25.

[0024] The detailed working process of the utility model is as follows:

[0025] Before use, the strip material is first fixed, and the second clamping plate 23 is pushed upward by the limit plate 25 to place one end of the strip material between the first clamping plate 22 and the second clamping plate 23, and then the limit plate 25 is loosened. Under the action of the spring, the first clamping plate 22 and the second clamping plate 23 are used to clamp and fix the material, and the other end is placed between the upper mold 3 and the lower mold 2. Then the device is started for processing, and two reciprocating cylinders 4 are used to control the up and down movement of the upper mold 3. When a stamping operation is completed, the upper mold 3 moves upward, driving the rack 10 to move upward. At this time, the rack 10 and the gear 9 are meshed and transmitted, thereby driving the gear 9 to rotate. The rotation of the gear 9 drives the No. 1 rotating shaft 8 to rotate, and then drives the driving wheel 19 to rotate. It should be noted that the gear 9 and the No. 1 rotating shaft 8 are connected in rotation through a one-way bearing. When the rack 10 moves downward to drive the gear 9 to rotate, the gear 9 will not drive the No. 1 rotating shaft 8 to rotate;

[0026] The driving wheel 19 rotates, and the driven wheel 20 and the second rotating shaft 15 are driven to rotate through the belt transmission. The rotation of the second rotating shaft 15 drives the rotating plate 16 to rotate, and then drives the arc-shaped support plate 17 and the rotating rod 18 to revolve. The arc-shaped support plate 17 will revolve along the semicircular groove 13. When the arc-shaped support plate 17 rotates out of the semicircular groove 13, the rotating rod 18 rotates into the vertical groove 14. At this time, the rotating rod 18 rotates and slides in the vertical groove 14, thereby causing the guide plate 12 to move. The guide plate 12 will slide along the slide rail 11 for a fixed distance. When the rotating rod 18 rotates out of the vertical groove 14, the movement stops and is maintained under the restriction of the arc-shaped support plate 17. This process is reciprocating and intermittent. Therefore, by cooperating with the upper mold 3 to intermittently move the guide plate 12, the raw material can be driven to be intermittently fed, and the stamping operation is more in line with actual production. While saving the use cost, it can also make the stamping operation and the feeding operation coordinated without manual adjustment, and has higher efficiency.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
