Preferably, bending die plates are arranged on the two sides of the plane supporting plates respectively, and the inner sides of the bending die plates are provided with arc chamfered surfaces respectively.
Preferably, the lower portion of the upper die plate is provided with a plurality of guide sleeves, the upper die plate is a square plate, the guide sleeves are positioned at four corners of the upper die plate respectively, and the upper portion of the lower die plate is provided with a plurality of guide posts corresponding to the guide sleeves.
By adoption of the aforementioned solution, in the present invention, when the upper die plate is utilized to perform downward pressing, the upper pressing plate and the arc concave dies are driven to move downwards, and the finished bending plate connecting piece can be obtained by one-time stamping under the matching of the workblank fixing plate, the arc convex dies, the plane supporting plates and the bending die plates. Complex positioning operation is avoided, the dimensional precision of the finished product is high, the production efficiency is improved, and the production cost is reduced.
Brief Description of Drawings FIG. 1 is a structural schematic diagram of an embodiment of the present invention.
Description of Embodiments
Embodiments of the present invention are described in detail below by combination with accompanying drawings, but the present invention can be implemented by multiple different modes limited and covered by the claims.
As shown in FIG. 1, an auto part one-time stamping die provided by an embodiment of the present invention comprises an upper die plate 1 and a lower die plate 2, wherein the upper die plate 1 is disposed above the lower die plate 2, an upper pressing plate 11 is fixedly arranged below the upper die plate 1, a workblank fixing plate 21 corresponding to the upper pressing plate 11 is disposed above the lower die plate 2, and a returning spring 6 is arranged between the bottom of the workblank fixing plate 21 and the lower die plate 2; arc male dies 22 are arranged on the two sides of the workblank fixing plate 21 respectively, arc female dies 12 corresponding to the arc male dies 22 are arranged on the two sides of the upper pressing plate 11 respectively, plane pressing plates 13 are disposed on the outer sides of the arc female dies 12 respectively, and plane supporting plates 23 corresponding to the plane pressing plates 13 are positioned on the outer sides of the arc male dies 22 respectively. Thus, workblank of the bending plate connecting piece 5 can be placed on the workblank fixing plate 21; when the upper pressing plate 11 performs downward pressing along with the upper die plate 1, the bottom surface of the upper pressing plate 11 comes into contact with the upper surface of the workblank of the bending plate connecting piece 5, and the workblank fixing plate 21 is pressed to the bottom to come into contact with the lower die plate 2. Meanwhile, the arc convex die 22 and the arc concave die 12 are utilized to form two arc-shaped protrusions on the workblank of the bending plate connecting piece 5; the fixation of the workblank on the outer sides of the arc-shaped protrusions is reinforced by utilizing the plane supporting plate 23 corresponding to the plane pressing plates 13, and end bending is facilitated; and the finished bending plate connecting piece can be obtained by one-time stamping under the matching of the workblank fixing plate, the arc convex dies, the plane supporting plates and bending die plates.
The bending die plates 24 are arranged on the two sides of the plane supporting plates 23 respectively in this embodiment, and the inner sides of the bending die plates 24 are provided with arc chamfered surfaces respectively. Thus, the two ends of the bending plate connecting piece 5 are bent upwards respectively, and smooth transition is performed at the bending position.
To reduce positioning times and improve product precision and production efficiency, the lower portion of the upper die plate 1 in this embodiment is provided with a plurality of guide sleeves 3, the upper die plate 1 is a square plate, the guide sleeves 3 are positioned at four corners of the upper die plate 1 respectively, and the upper portion of the lower die plate 2 is provided with a plurality of guide posts 4 corresponding to the guide sleeves 3.
What is described above is merely a preferred embodiment of the present invention and does not accordingly limit the patent scope of the present invention. Equivalent structures or equivalent process transformations which are performed by utilizing the specification and accompanying drawing contents of the present invention are directly or indirectly applied to other relevant technical fields and shall be included within the patent protection scope of the present invention in a similar way.
