Abstract

The invention discloses the process of a kind of loader intermediate input axle closed die forging, relate to Machining Technology field;Comprise the steps: by bar under technological requirement size, bar is heated to 1050 DEG C, jumping-up hydraulic press molding base of pre-upsetting, the blank of jumping-up is moved to that rotary forging press pendulum rolles over molding, Turnover Box cooling put into by forging that pendulum rolles over forming;The present invention can solve prior art loader intermediate input forging shaft low precision, die manufacturing cost height and the problem of poor working environment.

Description

The process of loader intermediate input axle closed die forging
Technical field
The present invention relates to Machining Technology field, especially a kind of dish class elongate articles closed die forging process.
Background technology
The intermediate input axle of loader is dish class elongate articles, and its forging is the most general uses traditional die hammer Forging Technology, and basic working procedure is heating furnace heating, the shaping of pneumatic hammer jumping-up, die hammer and punch press trimming;There are the following problems for this traditional Forging Technology: 1, severe operational environment, produces noise big;2, equipment is big to ground vibration, and equipment Foundations are complicated;3, Product Precision is poor, owing to die hammer guiding accuracy is poor, causes product die parting line to offset big, and the monolateral allowance of product is big;4, die manufacturing cost is high, and owing to forming process has the biggest impact, mould must be designed to the hugest, and to increase cushion faces, simultaneously because shape with impact, die wear is fast, causes die life low.
Summary of the invention
It is an object of the invention to provide the process of a kind of loader intermediate input axle closed die forging, it can solve prior art products low precision, die manufacturing cost height and the problem of poor working environment.
In order to solve the problems referred to above, the technical solution used in the present invention is:
The process of a kind of loader intermediate input axle closed die forging, comprises the following steps:
A, blanking: with band sawing machine, round steel is sawn into the round bar of technological requirement size;
B, heating: round bar sawed for step A is put into intermediate frequency heating, heating and temperature control is at 1150 DEG C ± 50 DEG C;
C, base: the round bar heated is put into pre-upsetting machine and pre-upsets, employing of pre-upsetting pre-upsets mould, and final forging temperature controls at 1050 DEG C ± 50 DEG C;
D, molding: base step C made moves to rotary forging press pendulum and rolles over molding, and mould rolles over mould for pendulum, and final forging temperature controls at 900 DEG C ~ 950 DEG C;
E, cooling: cool down in the intermediate input forging shaft rolling over molding through pendulum is put into Turnover Box.
In above technical scheme, further scheme is: mould of pre-upsetting described in step C includes big the least upper mold under the up big and down small lower mold of die cavity and a die cavity, the bottom of described lower mold is provided with through hole, the top of described upper mold is provided with through hole, described upper mold is connected with upper bolster by attachment means, it is provided with a pressure ram, described pressure ram and a pressure ram die holder in the through hole of described upper mold to connect.
Further: pendulum described in D step is rolled over mould and included that a pendulum with up-small and down-big die cavity rolles over upper mold and a pendulum with up big and down small die cavity rolles over lower mold, and the bottom of the die cavity that described pendulum rolles over lower mold is provided with a through hole.
Owing to have employed technique scheme, the present invention compared with prior art has the advantages that
1, using this technological method for processing, thinner bar can be selected to carry out electrical induction, blank can quickly heat, and production efficiency is high, and blank surface oxidation is few, and forging surface quality is good;
2, using this technological method for processing, use common hydraulic forging press jumping-up base, rotary forging press pendulum to roll over molding, die life is higher;Furthermore, due in forming process without impact shock, noise is little, and operator's labor intensity and work situation are greatly improved, and production efficiency is greatly improved;
3, using this technological method for processing, can use 200T enclosed rotary forging press, disposal molding, forming process is roll milling forming, and upper and lower mould magnitude of misalignment is the least, and the monolateral allowance of forging is few, and Product Precision is high.
Accompanying drawing explanation
Fig. 1 is mould assembly front view of pre-upsetting.
Fig. 2 is that pendulum rolles over mould assembly front view.
Detailed description of the invention
The present invention is further described by embodiment below in conjunction with the accompanying drawings: as shown in Fig. 1 ~ Fig. 2,
The process of a kind of loader intermediate input axle closed die forging, comprises the following steps:
