CN102172753A - Method for forging concave components - Google Patents

Abstract

The invention provides a method for forging concave components, which comprises the following steps: 1, merging two concave components into a merged forge piece according to the shapes of the two concave components, calculating material weight, and cutting blanks to be processed by using a band saw machine; 2, making the blanks to be processed into a blank piece; 3, forming by die forging; 4, trimming and punching a middle hole by using a trimming press; and 5, cutting the merged forging piece which is shaped by forging into two parts by using the band saw machine. The method provided by the invention has the advantages that, through simultaneously forging two concave components, the error displacement force generated by the blanks in the process of forging can be balanced effectively, thereby facilitating the flowing of metal in a cavity, further facilitating the forming, reducing the occurrence of the phenomenon that the running cavity is filled difficultly and the raised parts of the two ends are lack of material, and reducing the forging difficulty of concave components.

Description

The forging method of matrix member

Technical field

The present invention relates to the forging field, relate in particular to a kind of forging method of matrix member.

Background technology

At present, comprise the matrix member of a class fluted body structure in the bogie of rolling stock, its design feature is middle be difform groove (semicircle or square etc. structure), and protrude at two ends, and the material of mid portion is less.Usually adopt direct die forging in the prior art, be about to blank to be processed and be placed on the mould, be processed into the matrix member by forging machine.Reason owing to the self structure of matrix member, when treating turned blank by forging machine and forge, occur easily that die cavity is difficult for being full of and the two ends projection lacks the phenomenon of material, simultaneously, waste of material is serious, causes matrix member of the prior art to forge difficulty.

Summary of the invention

Technical problem to be solved by this invention is: a kind of forging method of matrix member is provided, solves the defective that prior art drop centre type member forges difficulty, realize reducing the forging difficulty of matrix member.

The invention provides a kind of forging method of matrix member, comprising:

Step 1, according to the shape of two matrix members, be combined into one and close forging, calculate material weight, and with band sawing machine well cutting blank to be processed;

Step 2, treat turned blank and carry out base and handle;

Step 3, die-forging forming;

Step 4, on clipping press, cut edge, dash middle hole;

Step 5, the forge piece blank reheating of closing with forging molding on band sawing machine are cut into two, form two matrix members.

The forging method of matrix member provided by the invention, by forging two matrix members of processing simultaneously, the effective offsetting power that blank produces in the balance forging process, helping metal flows in an actor's rendering of an operatic tune, thereby be convenient to moulding, reduce and to occur that die cavity is difficult for being full of and the two ends projection lacks the phenomenon of material, realize having reduced the forging difficulty of matrix member.

Description of drawings

In order to be illustrated more clearly in the embodiment of the invention or technical scheme of the prior art, to do one to the accompanying drawing of required use in embodiment or the description of the Prior Art below introduces simply, apparently, accompanying drawing in describing below is some embodiments of the present invention, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the flow chart of the forging method embodiment of matrix member of the present invention;

Fig. 2 is the structural representation of the blank of forging method embodiment step 4 acquisition of matrix member of the present invention;

Fig. 3 is the structural representation of the blank of forging method embodiment step 5 acquisition of matrix member of the present invention.

The specific embodiment

For the purpose, technical scheme and the advantage that make the embodiment of the invention clearer, below in conjunction with the accompanying drawing in the embodiment of the invention, technical scheme in the embodiment of the invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that is obtained under the creative work prerequisite.

Fig. 1 is the flow chart of the forging method embodiment of matrix member of the present invention.As shown in Figure 1, the forging method of present embodiment matrix member comprises:

Step 1, according to the shape of two matrix members, be combined into one and close forging, calculate material weight, and with band sawing machine well cutting blank to be processed.Concrete, will cut out the blank to be processed that is used to process two matrix members by step 1.

Step 2, treat turned blank and carry out base and handle.

Step 3, die-forging forming.

Step 4, on clipping press, cut edge, dash middle hole.Concrete, as shown in Figure 2, blank to be processed forms one and closes forging by what the first matrix member 1 and the second matrix member 2 were docking together after the processing through step 1-step 4.Owing to process two matrix members simultaneously, effectively the offsetting power that blank produces in the balance forging process helps metal and flows in an actor's rendering of an operatic tune, and has improved the forging efficient of matrix member.

Step 5, the forging that closes with forging molding on band sawing machine are cut into two, form two matrix members.Concrete, as shown in Figure 3, close forging cutting by band sawing machine with what step 4 processed, thereby form two matrix members, be i.e. the first matrix member 1 and the second matrix member 2.

The forging method of present embodiment matrix member, by forging two matrix members of processing simultaneously, the effective offsetting power that blank produces in the balance forging process, helping metal flows in an actor's rendering of an operatic tune, thereby be convenient to moulding, reduce and to occur that die cavity is difficult for being full of and the two ends projection lacks the phenomenon of material, realize having reduced the forging difficulty of matrix member.

It should be noted that at last: above embodiment only in order to technical scheme of the present invention to be described, is not intended to limit; Although with reference to previous embodiment the present invention is had been described in detail, those of ordinary skill in the art is to be understood that: it still can be made amendment to the technical scheme that aforementioned each embodiment put down in writing, and perhaps part technical characterictic wherein is equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution break away from the spirit and scope of various embodiments of the present invention technical scheme.

Claims (1)

1. the forging method of a matrix member is characterized in that, comprising:

Step 1, according to the shape of two matrix members, be combined into one and close forging, calculate material weight, and with band sawing machine well cutting blank to be processed;
