Abstract
The invention provides a flange punching blanking stamping device for an automobile exhaust pipe. The flange punching blanking stamping device for the automobile exhaust pipe comprises a bottom hydraulic device, a buffering spring, a female die, a contour cutter edge, a tooth-shaped line, a male die, a contour line, a tooth-shaped cutter edge, a top hydraulic device and a support. A gear line is arranged on the periphery of a groove in the top of the female die, the contour cutter edge is arranged on the outer side of a four-wheel line, the tooth-shaped cutter edge is arranged on the periphery of the protruding portion of the bottom of the male die, and the contour line is arranged on the periphery of the tooth-shaped line. The top hydraulic device pushes the male die to press downwards, primary trimming is conducted on the edge of a metal plate from top to bottom by the tooth-shaped cutter edge along the appearance of the tooth-shaped line, and after trimming is conducted, the edge of the metal plate is of a sawtooth shape. Then, the groove is pushed upwards through the bottom hydraulic device, secondary cutting is conducted from bottom to top by the contour cutter edge along the contour line, the sawtooth-shaped portion of the edge of the metal plate is cut off, and a needed shape is finally formed.
Description
Technical field
The invention belongs to the thick sheet metal component decompressor of a kind of automobile, be specifically related to automobile exhaust pipe flange punching and blanking decompressor.
Background technology
During automobile metal plate work punching press; trimming technology needs larger active force; metal has good ductility simultaneously; the edge deformation that often there will be trimming to cause in production process; as in uneven thickness;, particularly on some thicker metalworks, more easily there is such problem in the problems such as otch is unsmooth, plain bending.
Summary of the invention
For addressing the above problem, the invention provides the device of a kind of punching press and cutting thick metal plate, by positive and negative cutting twice, reduce incision lifting surface area, efficiently solve the problem of edge deformation in thick metal plate die cutting process.
A kind of automobile exhaust pipe flange punching and blanking decompressor, comprise: bottom liquid pressure device, buffer spring, die, the profile edge of a knife, teeth outline, punch, outline line, the teeth outline edge of a knife, top hydraulic means, support column, described bottom liquid pressure device is fixed on ground or platform, its top is provided with buffer spring, on described buffer spring, be provided with die, described die top groove edge is provided with the profile edge of a knife, described profile edge of a knife outer ring is provided with teeth outline, 50CM place, described die top is provided with punch, described punch protrudes punching press position arranged outside outline line, described outline line outer ring is provided with the teeth outline edge of a knife, described punch top is provided with hydraulic means, described lower curtate hydraulic means and top hydraulic means are connected and fixed with support column.
The present invention further improves and is: described buffer spring is provided with 4 active forces that are separately positioned in the time of cushioning punching press and trimming process under four angles of die, reduces sheet metal edge deformation probability, and described support column has four.
The present invention further improves and is: described teeth outline overlaps in vertical direction with the teeth outline edge of a knife, and in metallic plate punching and cutting process, teeth outline overlaps and cuts for the first time with the teeth outline edge of a knife.
The present invention further improves and is: the described profile edge of a knife overlaps in vertical direction with outline line, and in metallic plate punching and cutting process, the profile edge of a knife overlaps and cuts for the second time with outline line.
The present invention, to effectively simple, has solved the problem of being out of shape in thicker metallic plate punching and cutting process by the examination of secondary cut side.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Wherein: 1-bottom liquid pressure device, 2-buffer spring, 3-die, the 4-profile edge of a knife, 5-teeth outline, 6-punch, 7-outline line, the 8-teeth outline edge of a knife, 9-top hydraulic means, 10-support column.
