Abstract
The invention discloses a pressing plate, wherein the pressing plate is in a cross-shaped structure formed at one time; a round through hole is located in the centre of the pressing plate; a square groove is arranged on the through hole; the linear contact position of the through hole, the upper end and the lower end is a plane; arc tangent planes are arranged at the upper end and the lower end of the pressing plate; the left side of the pressing plate is a square plane; the right side of the pressing plate is a circular arc plane; round through holes are arranged at the left end and the right end of the pressing plate respectively; the bottom of the pressing plate is a corrugated plane; the pressing plate comprises following components in percentages by mass: 0.4-0.7% of carbon, 3-5% of nickel, 0.65-0.95% of molybdenum and the balance of iron. The pressing plate has the advantages of high tensile strength, high yield strength, easy installation, good engagement, low cost, one-step molding and so on.
Description
Technical field
The present invention relates to a kind of auto parts and components, be specifically related to a kind of gas and use pressing plate.
Background technology
Traditional press plate mechanism add need carry out repeatedly punch press man-hour, the car die worker combines, and has so just increased the fussy degree of work, in addition, owing to be repeatedly process to combine, causes lower even situation fracture of pressing plate compressive strength to take place easily.Middle work is many, and material and electric resources have also been caused unnecessary waste, has increased financial burden to enterprise simultaneously, has limited the benefit of enterprise, is unfavorable for the development of enterprise.
Therefore, a kind of tensile strength height, yield strength pressing plate high, that be prone to installation, low, the one-time formed PM technique moulding of cost are the current problems of demanding urgently studying.
Summary of the invention
The object of the present invention is to provide a kind of tensile strength height, high, the easy installation of yield strength, low, the one-time formed pressing plate of cost.
Technical scheme of the present invention is: a kind of pressing plate, described pressing plate are criss-cross one-shot forming structure, and said pressing plate center is a manhole; Through hole is provided with a square groove, and through hole is the plane with straight line contact position, place, two ends up and down, and said pressing plate has a circular arc tangent plane respectively in two ends up and down; The pressing plate left side is square, and the right side is an arc surface, and right ends is respectively arranged with a manhole; The pressing plate bottom surface is the ripple plane; Comprise the carbon that mass percent is 0.4%-0.7% in the constituent of said pressing plate, the nickel of 3%-5%, the molybdenum of 0.65%-0.95% and the iron of surplus.
In preferred embodiment of the present invention, the density of described pressing plate is 7.3g/cm3.
In preferred embodiment of the present invention, the hardness of said pressing plate is HRC37-44.
In preferred embodiment of the present invention, the tensile strength of described pressing plate is 1380MPa.
In preferred embodiment of the present invention, the yield strength of described pressing plate is 1000MPa.
According to the invention is a kind of pressing plate, this pressing plate have tensile strength height, yield strength high, be prone to install, mesh, effects such as cost is low, one-shot forming.
Description of drawings
Fig. 1 is the birds-eye view of this pressing plate in pressing plate one preferred embodiment of the present invention;
Fig. 2 is the front elevation of this pressing plate in pressing plate one preferred embodiment of the present invention;
Each mark is following in the accompanying drawing: 1, pressing plate, 2, the upper end, 3, the lower end, 4, the left side, 5, the right side, 6, the ripple plane.
The specific embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is set forth in detail, thereby protection scope of the present invention is made more explicit defining so that advantage of the present invention and characteristic can be easier to it will be appreciated by those skilled in the art that.
According to the invention is a kind of pressing plate, and shown in Fig. 1: a kind of pressing plate 1, pressing plate 1 are criss-cross one-shot forming structure; Pressing plate 1 center is a manhole; Be used for fixing on bearing, through hole is provided with a square groove, and groove is embedded on the projection of bearing and groove fit; Pressing plate 1 can be meshed with bearing, prevent that pressing plate 1 from skidding.Through hole and upper end 2, straight line contact position, 3 place, lower end are the plane, play the effect that prevents that pressing plate 1 from skidding equally.Pressing plate 1 upper end 2, lower end 3 have a circular arc tangent plane respectively, are used for cooperating with other parts, make pressing plate 1 stable.Pressing plate 1 left side 4 is square, and right side 5 is an arc surface, and right ends is respectively arranged with a manhole, is used for interting bearing.Pressing plate 1 bottom surface is ripple plane 6, pressing plate 1 is cooperated more with other parts agree with, and prevents to skid.
Comprise the carbon that mass percent is 0.4%-0.7% in the constituent of pressing plate 1, the nickel of 3%-5%, the molybdenum of 0.65%-0.95% and the iron of surplus.The density of pressing plate 1 is 7.3g/cm3, and the hardness of pressing plate 1 is HRC37-44, and the tensile strength of pressing plate 1 is 1380MPa, and the yield strength of pressing plate 1 is 1000MPa.
According to the invention is a kind of pressing plate, this pressing plate have tensile strength height, yield strength high, be prone to install, mesh, effects such as cost is low, one-shot forming.
The above is merely the specific embodiment of the present invention; But protection scope of the present invention is not limited thereto; Any those of ordinary skill in the art are in the technical scope that the present invention disclosed; Variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
