Automobile intercooler pipe grid forming die

Abstract

The invention discloses an automobile intercooler pipe grid forming die. The automobile intercooler pipe grid forming die comprises an upper die plate, a guiding sleeve and a lower die plate; spring screws are installed in the upper die plate; an upper cushion plate is fixed below the upper die plate; a pressing plate is arranged below the upper cushion plate; a male die is installed in the middle of the pressing plate; a guiding column is connected to the lower portion of the guiding sleeve; the upper portion of the guiding sleeve is fixedly connected with the upper die plate; a lower cushion plate is fixed to the lower die plate; the bottom of the guiding column is connected with the lower die plate; a female die is installed above the lower cushion plate; and a forming piece top plate is connected to the female die. After punching of a convex closure formed through the forming die, the surface intersection line of hole opening four-corner arcs and convex closure four-corner cones is lower than a straight side intersection line; in the assembling process of a pipe grid subjected to punch forming through the above forming method, after a pipe penetrates a pipe grid hole, the elasticity of a straight side is restored so that deformation is avoided, while reworking is eliminated, the product assembly quality and the production efficiency are improved, and the forming method has good reference significance in parts with similar using requirements.

Description

technical field [0001] The invention relates to the technical field of mold design and manufacture, in particular to a pipe grid forming mold for an automobile intercooler. Background technique [0002] As a supporting part of the supercharged engine supercharging system, the intercooler is used to reduce the temperature of the high-temperature air after supercharging, so as to reduce the heat load of the engine, increase the intake air volume, and then increase the power of the engine. For a supercharged engine, the intercooler is an important component of the supercharging system. [0003] The intercooler is mainly composed of air chambers, tube grids, heat dissipation pipes, heat dissipation belts, side plates and other parts. Among them, the pipe grids are the key connections to form a closed heat dissipation circulation system after cooperating with the heat dissipation pipes and air chambers. Components, tube grid forming quality—especially the punching accuracy and f...
