Problems solved by technology

Although this method can solve the problem of insufficient pressure of the press, the second stamping will cause the deformation of the channel after the first stamping, and the two stampings will also reduce production efficiency

Abstract

The invention discloses a hydraulic oil radiator mainboard stamping die and a using method thereof. The die comprises a discharging rod fixing plate, a discharging plate carrier rod, a top die fixing plate, a guide sleeve, a guide post, a lower die fixing plate, a section, a lower die, a discharging plate, a leveling spring, a male die, a male die fixing plate, a punch fixing post, a stop pin, a stop pin hole and a positioning pin, wherein the discharging rod fixing plate is fixed on the discharging plate carrier rod which passes through the upper die fixing plate, the male die fixing plate and the male die and is fixed on the discharging plate; the male die fixing plate and the male die are fixed on the upper die fixing plate in turn; the leveling spring is sleeved on the positioning pinand positioned between the male die and the discharging plate; and the lower die is fixed on the lower die fixing plate. The die is suitable for stamping a hydraulic oil radiator mainboard. The roundsection is arranged on the lower die and attached to the stop pin to be stamped. The die can be integrally arranged on a stamping mechanical platform for operation and production.

Description

technical field [0001] The invention relates to a die, in particular to a stamping die for a main board of a hydraulic oil radiator and a use method thereof. Background technique [0002] The hydraulic oil radiator is made of aluminum and dissipates heat through fins. The main board of the hydraulic oil radiator needs to punch out the through groove to install the pipe, so that the internal coolant can circulate. [0003] The traditional hydraulic oil radiator motherboard stamping die uses rubber pads to provide unloading force. The rubber pad is used to provide the unloading force. The rubber pad will absorb at least half of the pressure, which greatly increases the tonnage of the press. On the other hand, the rubber pad is easy to age under long-term oil immersion and harsh working environments. Need to be replaced regularly. However, the rubber pad can provide pressing force, prevent profile deformation and improve forming quality. [0004] In the case of limited pres...
