Abstract
Description
TECHNICAL FIELD
[0001] The utility model relates to hardware stamping part cylinder tee product processing field especially relates to a side core-pulling forming die structure. BACKGROUND
[0002] Since the tee product needs to be flanged from inside to outside, the production process needs to core-pull the inside of the circular pipe, so the process difficulty is quite complex, and the prior art is completed by product welding splice welding, so the product rigidity is low. SUMMARY
[0003] To solve the above problems, the technical scheme provides a side core-pulling forming die structure.
[0004] To achieve the above object, the technical scheme is as follows:
[0005] A side core-pulling forming die structure, comprising an upper die and a lower die wrapped around a product to be processed, the upper die is provided with a forming hole relative to the forming part of the product to be processed, further comprising a forming body located inside the product to be processed, further comprising a limiting part located on one side of the upper die for limiting the product to be processed and the forming body, and a pushing part located on the other side of the upper die for pushing the forming body.
[0006] In some implementations, the upper die and the lower die are detachably connected.
[0007] In some implementations, the forming body is spherical.
[0008] In some implementations, the end face of the pushing part is designed as a guide slope.
[0009] In some implementations, the limiting part is provided with a step for limiting the die.
[0010] The application has the following advantages:
[0011] The application wraps the product to be processed by the upper and lower dies, then limits one side of the product by the limiting part, and pushes the other side by the pushing part, so that the forming body is pushed out at the through hole of the product to be processed, so that a circular pipe is formed on the side edge by cooperating with the forming hole, so that the product is completed without welding, and the whole stamping forming mode is changed, which greatly improves the rigidity requirement of the product, greatly optimizes the production cost of the product compared with the original mode, and greatly improves the production efficiency. BRIEF DESCRIPTION OF DRAWINGS
[0012] In order to more clearly illustrate the technical scheme in the embodiments of the utility model, the following will briefly introduce the drawings needed to be used in the embodiment description.

[0017] In order to make the technical problems, technical schemes and beneficial effects solved by the utility model more clearly understood, the utility model is further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and do not limit the utility model.
[0018] Please refer to Figures 1-4 A side core-pulling forming die structure, including the upper die 2 and the lower die 3 covered on the product to be processed 1, the upper die 2 is provided with a forming hole 4 relative to the forming place of the product to be processed 1, further including the forming body 5 located in the product to be processed 1, further including the limiting part 6 located on one side of the upper die 2 for limiting the product to be processed 1 and the forming body 5, and the pushing part 7 located on the other side of the upper die 2 for pushing the forming body 5.
[0019] The application covers the product to be processed by the upper and lower dies, then limits one side of the product by the limiting part, pushes into the other side by the pushing part, so that the forming body is pushed out at the through hole of the product to be processed, so that the side edge is extruded into a circular tube by cooperating with the forming hole. In this way, welding is not needed, and the whole stamping forming mode is changed. Such production process greatly improves the rigidity requirement of the product, greatly optimizes the production cost of the product compared with the original mode, and greatly improves the production efficiency.
[0020] Further, the diameter of the formed steel ball needs to be smaller than the inner diameter size of the cylindrical product by 0.1mm-0.2mm.
[0021] In the embodiment, the upper die 2 and the lower die 3 are detachably connected, facilitating demolding.
[0022] In the embodiment, the forming body 5 is spherical.
[0023] In the embodiment, the end face of the pushing part 7 is designed as a guide inclined surface, referring to the attached Figure 3 , after the pushing part designed with the inclined surface is pushed in, the formed ball is driven to move upward, so as to extrude the product flanging.
[0024] In the present embodiment, the limiting portion 6 is provided with a step 8 for limiting the mold.
[0025] The above merely provides the preferred embodiments of the present application, but is not intended to limit the scope of the present application, and other embodiments which have the same principles and basic structure as the present application are within the scope of the present application.
