Description
Technical Field
The utility model belongs to the technical field of side-impact molded products, and particularly relates to a deep-drawn product prefabricated part capable of preventing side-impact molding cracking.
Background
Deep drawingThe process involves stretching the metal to increase the strength of the workpiece, pushing it in all directions to help evenly distribute the stress. Deep drawing processes have been applied to produce a variety of different structural products. Different materials have different degrees of stiffness, porosity and elasticity, that is, the deformation of different materials during deep drawing is different. In the actual operation process, when embossing materials with heat preservation effects such as SUS430, SUS304 and aluminum materials are subjected to deep drawing molding to form products with special-shaped askew necks, side punching molding cracking often occurs,the conventional treatment method is to finish the die or lead the R angle, but the finishing still cannot solve the problem, and the cracking problem can be further solved only by adding the die and the process, so that the cost is increased.
Disclosure of Invention
The utility model provides a deep-drawn product prefabricated member capable of preventing side-punching forming cracking, which can effectively prevent cracking phenomenon generated during side-punching.
The aim of the utility model is achieved by the following technical scheme:
the deep-drawing product prefabricated member capable of preventing side-punching forming cracking comprises a hollow main body cavity, wherein a pipe orifice is arranged on one side of the main body cavity in an extending mode, the section of the pipe orifice is arc-shaped, and a stretching residual material edge is arranged on the edge of the pipe orifice in an outwards extending mode.
Preferably, one end of the main body cavity is provided with a closing-in section gradually closing in towards the pipe orifice direction, and the stretching remainder edge is from the closing-in section to the end of the pipe orifice.
Preferably, the stretch panel extends 28mm + -3 mm outwardly from the nozzle edge.
Preferably, the material of the stretch product preform is SUS430 or SUS304 or aluminum.
Preferably, the stretching surplus material edge extends outwards within 28mm plus or minus 3mm at the joint of the pipe orifice and the closing-in section.
The beneficial effects of the utility model are as follows: through increasing the clout limit for the product is in the side blow shaping in-process, tears and acts on the flange edge, thereby guarantees the not fracture of product, improves the yields of product, the effectual cost is practiced thrift.

Description of the embodiments
The technical scheme of the utility model is specifically described in the following embodiment, and the utility model discloses a side-impact-forming-cracking-preventing deep-drawing product prefabricated member, which is also a deep-drawing member as shown in fig. 2-3, and comprises a hollow main body cavity 1, wherein one side of the main body cavity 1 is provided with a pipe orifice 3 in an extending manner, and the pipe orifice 3 is of a special-shaped structure, namely, is cut into a certain radian and is arc-shaped. Further, one end of the main body cavity 1 is provided with a closing-in section 2 gradually closing in towards the pipe orifice direction, and the pipe orifice 3 is connected with the closing-in section 2. The structure and the size of the main body cavity 1 and the pipe orifice and the closing-in section 2 are equivalent to those of the product to be molded in fig. 1.
The prefabricated member further comprises a stretching edge 4 arranged on the edge of the whole product, and a stretching remainder edge 31 is arranged on the edge of the pipe orifice 3 of the prefabricated member in an outward extending mode in order to avoid cracking of the pipe orifice in the subsequent side punching process. The material of the stretch product prefabricated part is SUS430, SUS304 or aluminum material, the stretch material edge 31 has a certain flow rate, and the outward extension length l of the pipe orifice edge is 28mm plus or minus 3mm. Specifically, the stretching remainder 31 starts from the closing-in section 2 to the end of the nozzle 3. The stretching surplus material edge 31 extends outwards by a distance l within 28mm plus or minus 3mm from the edge of the stretching edge 4 of the R angle at the joint of the pipe orifice 3 and the closing section 2. When the prefabricated part is punched, the cracking problem caused by punching can be well solved. The utility model utilizes the principle that due to the structural characteristics of the inner R angle and the outer R angle, the material forming pulling and extrusion at the R angle can flow during Z-shaped stamping, and the cracking characteristic can be well transferred to the waste material only by increasing the stretching surplus material edge, so that the cracking of the final product is avoided, and the cost of the die and the process cost are saved. The practicability is strong.
There are various embodiments of the present utility model. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of the utility model claimed.
