A kind of progressive mold of high-turned nut plate with cooling mechanism

Abstract

The invention discloses a progressive mold of a high hole flanging nut plate with a cooling mechanism. The mold comprises an upper mold base, a lower mold base, a blanking mechanism, a drawing mechanism, a ladle receiving mechanism and a separating mechanism. The ladle receiving mechanism comprises a male mold fixing plate, a male mold, a female mold, a female mold assembly, a material floating mechanism, a cooling mechanism and a demolding mechanism, wherein the male mold fixing plate is arranged on the upper mold base; the male mold assembly comprises a plurality of male molds; the female mold fixing plate is arranged on the lower mold base; the female mold assembly comprise a plurality of female molds; the material floating mechanism comprises a material floating back plate, a material floating plate and a lifting hook, and the lifting hook is arranged on the material floating plate; the cooling mechanism comprises coil pipes and connecting pipes, the coil pipes are arranged on the outer side of the female mold, and the connecting pipes are connected to the coil pipes of adjacent two female molds, respectively; and the demolding mechanism is arranged on the lower mold base. Compared with prior art, the male mold is directly fixed on the upper mold base through the male mold fixing plate; during forming, ladles are received by virtue of a force of a machine tool, and the forming force is relatively great, so that the product quality is guaranteed; a material strip is hung below the material floating plate, so that the material strip is smooth; and the cooling mechanism cools the female mold, so that the product quality is further improved.

Description

technical field [0001] The invention belongs to the technical field of mold equipment, and in particular relates to a progressive mold with a cooling mechanism for a high-turned nut plate. Background technique [0002] The progressive die is composed of multiple stations, and each station is connected in sequence to complete different processing. A series of different stamping processes are completed in one formation of the punching machine. The distance moves the material forward, so that multiple stations can be completed on a pair of molds, generally including punching, blanking, bending, trimming, stretching and other stations, which are safe to operate, easy to automate, and can be used High-speed punch production, reduced punch and site area, reduced transportation of semi-finished products and warehouse occupancy, high productivity, etc. [0003] In the prior art, for the upward forming process, in order to ensure the smoothness of the material belt during the formin...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, for the upward forming process, in order to ensure the smoothness of the material belt during the forming process, the forming punch is usually installed on the upper pressing plate, and the force required for forming is provided by the pressure source of the pressing plate , however, for the high-turned nut plate, the required force is very large when closing the bag. If the punch is installed on the upper binder plate, it will not be able to provide such a large forming force, which will affect the product quality.

At the same time, when the package is thickened, due to the severe friction between the parts and the die and the rapid deformation of the material itself, a large amount of heat is generated at the moment of forming, so that the temperature of the die rises quickly, resulting in deformation, hardness reduction, Adhesion with the product, roughening of the die, etc.
