Abstract
The present invention discloses a kind of forging method of bar jumping-up wooden club base, on the basis of conventional method for upsetting, two work step moldings are carried out by using two kinds of cavities, stapling head is fixed by mold closure, the enclosure space of basic fitting bar is formed first with a work step mold cavity and stapling head, it prevents bar from being moved along Impact direction in upsetting process, is more than 1 in ratio of height to diameter:The case where necessarily leading to bending after 3 then carries out finish-forging in two work step mold cavities, solves ratio of height to diameter up to the forming defects such as bending, distortion in 10.4 bar upsetting processes.The ratio of height to diameter of ingot blank or bar is effectively reduced by using this method, and to the development conducive to follow-up forging process, a kind of new selection approach is provided than the ingot blank cogging of forging or bar jumping-up for larger ratio of height to diameter, big cross section.
Description
Technical field
The present invention relates to technical field of forging, and in particular to a kind of forging method of bar jumping-up wooden club base is suitable for forging
Make wooden club base of the height with diameter ratio up to 10.4.
Background technology
Complex-shaped with the development of aerospace, the bigger forging in cross section is more and more, due to smelting original at present
Substantially uniform material is bar stock, causes the blocking fire time of the forging more, weight is larger, feeds intake more, in forging process for fuel process
In can cause the huge waste of production cost.Since the ratio of height to diameter of bar used in the process of forging process for fuel is larger, such as using conventional
Method for upsetting, more fire time carry out, and forging performance is difficult to ensure, while bending is also easy to produce in upsetting process, and due to bar compared with
Long, alignment work difficulty is also larger.
Invention content
In view of the above situation of the prior art, the object of the present invention is to provide a kind of forging sides of bar jumping-up wooden club base
Method, to solve height with diameter ratio up to the bending during 10.4 bar jumping-up wooden club base, the forming defects such as distortion.
The above-mentioned purpose of the present invention is realized using technical solution below：
A kind of forging method of bar jumping-up wooden club base, including：
Step 1：Mold, punch, stapling head are preheated in tooling preheating furnace；
Step 2：Installation mold；
Step 3：Clamp bar one end using stapling head, move to mold after a work step mold cavity and fix, mold cavity and
Stapling head forms the enclosure space that bar is located therein, upset to the bar other end using punch, carries out a work step molding；
Step 4：After the completion of the molding of one work step, mold is opened, the clamp for completing the molding bar of a work step will be clipped rapidly
Head moves to the stapling head position of two work step mold cavities, and mold matching clamp carries out finish-forging after gripping binding clip.
Further, the mold is the double-cavity mould for including a work step mold cavity and two work step mold cavities, can
To reduce the transit time between the molding of one, two work steps.
The one work step cavity may include the end face and the smaller end face of another diameter that one is relatively large in diameter, centre setting
There is the transition region for preventing big small end face joining place from crushing.To adapt to forging of the both ends cross section than differing larger wooden club base.
The mold, stapling head, punch material need to be chosen according to heating temperature, general to choose 5CrNiMo mould steel
.
The beneficial effects of the invention are as follows：On the basis of conventional method for upsetting, two work steps are carried out by using two kinds of cavities
Molding fixes stapling head by mold closure, and basic fitting bar is formed first with a work step mold cavity and stapling head
Enclosure space, prevent bar from being moved along Impact direction in upsetting process, be more than 1 in ratio of height to diameter:Necessarily lead to bending after 3
Situation, then two work step mold cavities carry out finish-forging, solve ratio of height to diameter up in 10.4 bar upsetting process bending,
The forming defects such as distortion.The ratio of height to diameter of ingot blank or bar is effectively reduced by using this method, to conducive to follow-up forging work
The development of sequence provides a kind of new selection approach for larger ratio of height to diameter, big cross section than the ingot blank cogging of forging or bar jumping-up.
Description of the drawings
Fig. 1 is the forging tooling schematic diagram used in the method for the invention.
Specific implementation mode
Object, technical solution and advantage for a clearer understanding of the present invention, with reference to the accompanying drawings and embodiments, to this
Invention is further elaborated.
A kind of engine forging material is 15-5PH stainless steels, at present since the forging both ends cross section is more larger than difference,
The diameter for choosing bar in maximum cross section is such as pressed, charged material weight is larger, and cross section smaller area can be caused in forging forming process
The middle huge waste of blank, therefore design the wooden club base for adapting to both ends cross section, large end face diameter 38.5mm, height
20mm transition regions are designed in 55mm, small end face diameter 25mm, height 60mm, centre to prevent big small end face junction from crushing.Base
Material uses a diameter of 25mm, is highly 260mm, highly with diameter ratio up to 10.4.On the basis of conventional method for upsetting, this is pre-
Bar need to be divided to two work steps by forging process, and forge tooling using shown in Fig. 1.The mold 1 used in forging process is amphitypy
Cavity mould, for the first work step from 260mm jumping-ups to 204mm, the first work step cavity 8 is large end face diameter 30mm, length 124mm, small
20mm transition regions are designed in end face diameter 25mm, height 60mm, centre to prevent big small end face joining place from crushing.Second work step from
204mm is upset to 155mm, and the second work step cavity 4 is consistent with the wooden club base of design.Forging process is to pass through clamp using clamp 6
First 7 clamp bar one end, and move to a work step mold cavity stapling head placement position 5, and bar is transferred to mold the with clamp
One work step cavity, stapling head move to placement position, and mold is closed, and fixes stapling head, mold cavity and stapling head are formed substantially
The enclosure space of fitting bar is more than 1 in ratio of height to diameter to prevent bar from being moved along Impact direction in upsetting process:It must after 3
The case where so generating bending.It is upset to the bar other end followed by the first work step punch 2, carry out a work step molding.Later, it beats
Mold, clamp of holding with a firm grip rapidly are transferred to the second work step cavity, and mold is closed grip jaw head, complete using the second work step punch 3
It is upset at the second work step.In above-mentioned forging process, the mold, stapling head, punch are both needed to be preheated, to prevent surface from swashing
The generation of cold tissue.The mold, stapling head, punch material need to be chosen according to heating temperature, general to choose 5CrNiMo moulds
Has steel.
The forging formed by above-mentioned forging process, ratio of height to diameter up to 10.4, surface without bending, distort, crush phenomenon, rear
Continuous forging process is smoothly molded when carrying out, and the structure property of final molding forging is good.
