A three-in-one stamping die and process for a main board of a water tank

Abstract

The invention provides a three-in-one stamping die for a main board of a radiator. The three-in-one stamping die comprises an upper die, a lower die, an inner guide post and guide sleeve component and an outer guide post and guide sleeve component. The upper die comprises an upper die plate, a punch-retainer plate, a notching punch and a punch-matrix, and the lower die comprises a lower die base, a matrix backing plate, a notching matrix and a cavity plate, wherein the punch-retainer plate is connected with the bottom surface of the upper die plate, the notching punch is arranged on the punch-retainer plate, the punch-matrix is connected with the bottom surface of the punch-retainer plate, the matrix backing plate is arranged on the top surface of the lower die base, and the cavity plate is arranged on the top surface of the matrix backing plate. The invention further provides a three-in-one stamping technology for the main board of the radiator. The three-in-one stamping die and the three-in-one stamping technology for the main board of the radiator have the advantages that a trimming die, a bending die and a notching die of the main board of the radiator are combined into one die, so that production efficiency is improved; since the number of repeated positioning times is decreased, manufacturing precision can be improved effectively.

Description

technical field [0001] The invention relates to molds, in particular to a three-in-one stamping mold and process for a main board of a water tank. Background technique [0002] The car water tank, also known as the radiator, is the main part of the car cooling system. Its function is to dissipate heat. The cooling water absorbs heat in the water jacket, flows to the radiator, dissipates the heat, and then returns to the water jacket to circulate. The purpose of regulating the temperature of the car engine. The water tank main board is an important component of the automobile water tank. The water tank main board is an aluminum part, and the plate is stamped through a mold to obtain the required shape and size. The traditional processing technology of water tank main board stamping die usually includes four sets of single punch dies, which can be divided into forming die, trimming die, bending die and punching die according to the order from front to back. Many molds, this ...

Problems solved by technology

The traditional processing technology of water tank main board stamping die usually includes four sets of single punch dies, which can be divided into forming die, trimming die, bending die and punching die according to the order from front to back. Many molds, this kind of manufacturing method is cumbersome, consumes a lot of working hours, long processing cycle, low efficiency, and requires repeated positioning to cause error accumulation, resulting in greatly reduced dimensional accuracy of stamping parts, and it is easy to produce bumps on the surface, etc. defect
