Abstract

The invention discloses a pre-upsetting die for an intermediate input shaft of a loading machine, and relates to the technical field of machining. The pre-upsetting die comprises a lower die with a big-end-up cavity, and an upper die with a big-end-down cavity, wherein a through hole is formed in the lower portion of the lower die, a through hole is formed in the upper portion of the upper die, the upper die is connected with an upper die holder through a connecting device, and an extrusion rod is arranged in the through hole of the upper die, and connected with an extrusion rod die holder. The pre-upsetting die can solve the problems that in the prior art, in the process of upsetting of intermediate input shafts of loading machines, the production cost is high, and the working environment is poor.

Description

Loading machine intermediate input axle is pre-upset mould
Technical field
The present invention relates to Machining Technology field, especially a kind of dish class elongate articles is pre-upset mould.
Background technology
The intermediate input axle of loading machine is dish class elongate articles, and its forging is general in the past adopts traditional die hammer Forging Technology, and basic working procedure is heating furnace heating, the shaping of pneumatic hammer jumping-up bar base, die hammer and punch press trimming etc.; There are the following problems: 1, severe operational environment wherein to use pneumatic hammer jumping-up bar preforming, produces noise large; 2, equipment is large to ground vibration, and Equipment Foundations are complicated; 3, the bar of jumping-up base also needs again to heat before die hammer is shaping, increases production cost.
Summary of the invention
The object of this invention is to provide a kind of loading machine intermediate input axle to pre-upset mould, it can solve the problem of the high and poor working environment of existing production cost.
In order to solve the problem, the technical solution used in the present invention is:
A kind of loading machine intermediate input axle is pre-upset mould, large little patrix under comprising the up big and down small counterdie of die cavity and a die cavity, the bottom of described counterdie is provided with through hole, the top of described patrix is provided with through hole, described patrix is connected with upper bolster by jockey, be provided with a pressure ram in the through hole of described patrix, described pressure ram is connected with a pressure ram die holder.
In above technical scheme, further scheme is: described counterdie top is provided with boss, and described patrix bottom is provided with the groove corresponding to described boss, and described counterdie is crimped by described boss and described groove with described patrix.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, adopt mould of pre-upsetting to carry out base, thinner bar can be selected to make raw material, cost of material reduces;
2, adopt common hydraulic forging press jumping-up base, upsetting process impacts less, and labor strength, working environment noise greatly reduce, and production efficiency improves greatly;
3, base in the mould of pre-upsetting closed, base process blank temperature declines comparatively slow, can save shaping before again by the process of blank heating, save heating cost.
Accompanying drawing explanation
Fig. 1 is mould assembly front view of pre-upsetting.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is further described: as shown in Figure 1,
A kind of loading machine intermediate input axle is pre-upset mould, large little patrix 3 under comprising the up big and down small counterdie 1 of die cavity and a die cavity, the bottom of counterdie 1 is provided with the through hole placing blank 2, the top of patrix 3 is provided with through hole, patrix 3 is connected with upper bolster 4 by connecting bolt, be provided with a pressure ram 5 in the through hole of patrix 3, pressure ram 5 and a pressure ram die holder 6 are threaded connection; Counterdie 1 top is provided with boss, and the bottom of patrix 3 is provided with the groove corresponding to boss, and counterdie 1 is crimped by boss and groove with patrix 3; After blank 2 puts into the die cavity of counterdie 1 and the die cavity of patrix 3, pressure ram 5 moves up and down under the drive of jumping-up hydraulic press, and jumping-up blank 2 is until jumping-up operation completes.
