And adjusting the forming angle to meet the technical requirements of the original bent drawing.

Description

End plate splayed forging die

Technical Field

The utility model relates to an end plate eight characters forges mould.

Background

In the prior art, the rubber lining plate for the freight locomotive is made of 45# steel and needs to be processed by a hot forging process. The original process comprises the following steps: unloading + heating + forging + side cut + heating + bending, the process is complicated because through 2 heating processes, energy resource consumption is big, and surface quality can't guarantee, and the department of bending stress concentration has the fracture risk.

SUMMERY OF THE UTILITY MODEL

The utility model aims to overcome the defect that exists among the prior art, provide an end plate eight characters forges mould, the cancellation process of bending needs one shot forming to accomplish and forges the processing, has increased forged the degree of difficulty. And adjusting the forming angle to meet the technical requirements of the original bent drawing.

In order to realize the above object, the technical scheme of the utility model provides an end plate eight characters forges mould, including last mould, with go up mould matched with lower mould, last mould chamber has on the mould, lower mould chamber has on the lower mould, it is the splayed to go up the mould chamber, lower mould chamber is the splayed, go up the mould and be provided with hasp structure, four between four bights of lower mould the hasp structure is located the mould chamber respectively perhaps four sides in the front, back, left and right of lower mould chamber, hasp structure including offering go up the mould/go up the constant head tank in four bights of one in the two of the lower mould on four bights, set up in the two another four bights with constant head tank matched with location is protruding.

The further improvement is that: the positioning groove on the same side of the upper die/the lower die is provided with a straight chamfer, and the positioning groove on the opposite side is provided with an arc chamfer.

The further improvement is that: the roughness of the upper die cavity and the lower die cavity is 0.8.

The further improvement is that: the heat treatment hardness of the upper die and the lower die is HRC 44-48.

The utility model has the advantages and the beneficial effects that: the performance and the precision of one shot forming product can satisfy customer's demand, have avoided the problem that secondary repeated heating caused energy consumption height, surface quality are poor, have reduced product cost, have improved production efficiency, through canceling the process of bending, have eliminated because the fracture risk that bends and produce, have improved the reliability that the product used, 4 angle hasps around the mould increases in addition, eliminate the dislocation power and mould loss.

Detailed Description

The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

As shown in fig. 1-4, an end plate splayed forging die comprises an upper die 1 and a lower die 3 matched with the upper die 1, wherein an upper die cavity 2 is arranged on the upper die 1, a lower die cavity 4 is arranged on the lower die 3, the upper die cavity 2 is splayed, the lower die cavity 4 is inverted splayed, a locking structure is arranged between four corners of the upper die 1 and the lower die 3, the four locking structures are respectively positioned on the upper die cavity 2 or the front, rear, left and right sides of the lower die cavity 4, and the locking structure comprises positioning grooves 6 arranged on four corners of one of the upper die 1/the lower die 3 and positioning protrusions 5 arranged on four corners of the other of the two and matched with the positioning grooves 6.

In order to further eliminate the offset force and the die loss, the positioning groove 6 on the same side of the upper die 1/the lower die 3 has a straight chamfer, and the positioning groove 6 on the opposite side has a circular arc chamfer.

In order to improve the accuracy of the processed product, the roughness of the upper cavity 2 and the lower cavity 4 is 0.8.

In order to improve the strength and the service life of the die, the heat treatment hardness of the upper die 1 and the lower die 3 is HRC 44-48.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
