Description

Stamping die for toothed ring products

Technical Field

The utility model belongs to the technical field of stamping dies, and particularly relates to a stamping die for a toothed ring product.

Background

The press forming is a process for forming a workpiece (stamping part) of a desired shape and size by applying an external force to a plate, a strip, a pipe, a profile, etc. by a press and a die to cause plastic deformation or separation. The stamping die is the most widely used forming die in stamping forming. The die is usually composed of an upper die and a lower die which are matched with each other, and a required product is punched through the matching of a concave die, a convex die and a punch. However, for some products with special structures, such as the product shown in fig. 1, the annular product with the tooth-like structure 62 on the end surface needs to be stamped on the surface 61, and the conventional stamping die cannot be used.

Detailed Description

The utility model discloses a stamping die for a toothed ring product, which is shown in combination with figures 2-4 and comprises an upper die and a lower die which are matched with each other, wherein the upper die comprises an upper die seat and an upper base plate 1 arranged below the upper die seat, a bump punch 5 for stamping the product is vertically connected to the upper base plate 1, and the lower end of the bump punch 5 sequentially penetrates through a punch fixing plate 2, a stripping base plate 3 and a stripping plate 4. The lower die comprises a lower die base and a fixed supporting block 211 arranged above the lower die base, wherein a transversely arranged forming supporting rod 21 is connected to the fixed supporting block 211, one end of the forming supporting rod 21 is connected with the fixed supporting block 211, the other end of the forming supporting rod is connected with a rotating supporting block 22 arranged on one side of the fixed supporting block 211, and the rotating supporting block is in pivot connection with the lower base plate 7. During punching, the forming support rod 21 is sleeved in the product 6, and one end of the forming support rod is supported by the rotary support block 22 to avoid inclined stress fracture caused by stress in the punching process. The forming support bar 21 completes the stamping of the surface of the product through the cooperation with the bump punch 5. The upper end of the rotary supporting block 22 supports the other end of the forming supporting rod 21 and can rotate around a pivot. The rotary support block 22 is opened by rotation, and after the product is taken out or placed, the rotary support block 22 is closed, so that the forming support bar 21 is erected at the upper end of the rotary support block 22.

In order to avoid that the rotary supporting block 22 is not rotated in place and does not support the forming supporting rod 21 well, the forming supporting rod 21 is broken in the stamping process, and the utility model is also provided with an induction control component.

Specifically, the other end of the rotary supporting block 22 is connected with an induction control assembly, the induction control assembly comprises a first probe 10 and a spring 11 arranged below the first probe 10, a second probe 9 is arranged on the other side of the first probe 10, and one end of the second probe 9 is connected with a fault detection switch 8 arranged outside the stamping die. Further, the first probe 10 is disposed in the lower pad 7, the spring 11 is disposed in the lower die holder 8, and pressing the first probe 10 drives the spring 11 to compress in the lower die holder.

The upper end of the first probe 10 is placed at the rotation-to-site of the rotation support block 22. The lower end of the first probe 10 is provided with a smooth notch 101, and the upper end of the second probe 9 is arranged in the smooth notch 101. The triggering principle is that when the rotary supporting block 22 is closed in place, the rotary supporting block is contacted with the top of the first probe 10 to press the spring 11 downwards, at the moment, when the first probe 10 moves downwards, the upper end of the second probe 9 slides out of the smooth notch 101, so that the error detection switch 8 is driven to be opened by abutting against the direction of the error detection switch 8, the error detection switch 8 is connected with a circuit of a stamping die, and a complete electric loop can be formed when the error detection switch 8 is opened. Indicating that the rotary support block 22 is rotating in place, the punch will work properly.

Finally, it should be noted that: the terms "upper," "lower," "left," "right," "vertical," "horizontal," "inner," "outer," and the like refer to an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the utility model and simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
