Description
Technical field
The utility model relates to a kind of automobile lower protective plate screw decompressor.
Background technology
Automobile lower protective plate is mounted in for the protection of one of automobile engine piece of baffle plate on automobile chassis, and its shape is consistent with the spatial form of engine bottom, and the lower backplate of automobile has multiple installation screw, and these screws are a kind of holes needing to be with concave edge.In the automobile lower protective plate of routine is produced, the installation screw on automobile lower protective plate uses electric drill to carry out perforate, and the trepanning velocity of this mode of production is very slow, and disposablely cannot process the screw of concave edge in band, production efficiency is low.
Summary of the invention
The purpose of this utility model is to provide a kind of automobile lower protective plate screw decompressor, it solves deficiency of the prior art, and this decompressor disposablely can process the screw of concave edge in band, and not only ram efficiency is high, and the product quality stamped out is high.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of automobile lower protective plate screw decompressor, it comprises punching press platform, upper punching die and lower punching die, described punching press platform is provided with backing plate, and on punching press platform, be vertically provided with at least three parallel leads; Described decompressor also comprises the cylinder driving upper punching die to move up and down along lead; Described lower punching die is arranged on backing plate, the center of described lower punching die has reverse frustoconic groove, what be provided with projection at the middle part of reverse frustoconic groove rushes axle, described upper punching die is arranged on the lower end of cylinder, on upper punching die, under correspondence, on punching die, the position of reverse frustoconic groove is provided with the plush copper with its mating shapes, and have punching at the middle part of plush copper, described punching with rush axle be centrally located on the vertical line of same ground, and the large 0.2-0.5mm of diameter of the diameter specific impulse axle of punching, in the outlet of porose of the side opening of punching.
Further, described backing plate is provided with the corresponding installation screw in position with lower punching die, and lower punching die is fixedly mounted on backing plate by screw.
Further, the gentle cylinder of described upper punching die is provided with the corresponding installation screw in position, and upper punching die is fixedly mounted on cylinder by screw.
Further, the large 0.3mm of diameter of the diameter specific impulse axle of punching.
Further, described lead is four, is arranged at the flat edge of table of punching press uniformly.
The utility model has following beneficial effect:
(1) after adopting above-mentioned structure, the screw of automobile lower protective plate can be once stamping on mould, speed of production is improved greatly, because the next to axis that rushes in lower diel is reserved with reverse frustoconic groove, punching is opened in the middle part of the plush copper of upper diel, when diel is applied on lower backplate, rushing axle enters in punching, lower backplate will be gone out a screw, on mould, reverse frustoconic groove and plush copper extrude the limit, hole of an indent on screw limit simultaneously, the work of perforate and flanging once completes, the hole sheet that mould sweeps away is exported by the hole sheet of punching side and spills,
(2) owing to being vertically provided with at least three parallel guide posts on punching press platform, depth of parallelism during punching press can be improved when punching press, product can be made more easily to be washed out, improve the product quality of punching press.
Accompanying drawing explanation
Fig. 1 is the operating diagram of the utility model embodiment.
