Abstract
The present invention relates to a kind of production technologies of thrust wheel side cover, and rod iron is cut into several segments with cutting machine first；The several segments rod iron after cutting is sent to being heated in stove to several segments rod iron, stove temperature is controlled at 1100-1300 DEG C, until dark red state occurs in the surface of rod iron；Aglow rod iron after processing is put into pneumatic hammer and carries out preliminary moulding；Rod iron after preliminary moulding is put into the mold cavity of forging machine, forging machine carries out punch forming to rod iron；By stamping forming forge piece, it is punched out according to the needs of forging；Forging is put into shaving die, extra overlap is cut off, thrust wheel side cover can be obtained, finally waits natural cooling, outbound.The present invention is put into special die using forge piece and passes through forging machine punch forming, production efficiency is greatly improved, not only defect gas leakage, oil leak existing for the existing casting technique of very good solution, but also forging plays the role of refining metal grain, intensity is higher than casting, and product is made more to adapt to varying environment use.
Description
Technical field
The present invention relates to thrust wheel side cover processing technologies, and in particular to a kind of production technology of thrust wheel side cover.
Background technique
Thrust wheel is the important component of crawler-mounted excavator walking and support system, it is generally the case that thrust wheel is subject to
The carrier of whole machinery weight, technical requirements are higher, and thrust wheel side cover is sealing, fixes and protect the most important of thrust wheel
Component, but thrust wheel side cover currently on the market is made using gravitational casting, the production that this technique is made
There are following defects for product:
1, thrust wheel side cover mechanical performance is not so good as forging, is easy to appear organizational coarseness, sand holes, segregation, loose, stomata, slag inclusion etc.
Various problems；
2, in the casting of sand part, single-piece, in small batches, labor intensity of workers is big and need to additionally make sand core；
3, casting quality is unstable, and process is more, and influence factor is complicated, easily causes many defects.
Summary of the invention
In place of overcoming the above deficiencies in the existing technologies, the purpose of the present invention is to provide a kind of thrust wheel sides
The production technology of lid, it is the simple process, easy to implement, and processing efficiency is higher, rejection rate is low.
To achieve the above object, The technical solution adopted by the invention is as follows: a kind of production technology of thrust wheel side cover, including
Following steps:
A, rod iron blanking: is cut into several segments with cutting machine；
B, it heats: the several segments rod iron after cutting is sent by conveyer belt to being heated in stove to several segments rod iron, stove
Temperature is controlled at 1100-1300 DEG C, until dark red state occurs in the surface of rod iron；
C, preliminary moulding: the aglow rod iron after step B processing being put into pneumatic hammer and carries out preliminary moulding, to meet postorder processing
It is required that；
D, main mould form: the rod iron after moulding preliminary in step C is put into the mold cavity of forging machine, forging machine to copper rod into
Row punch forming；
E, it machines: the stamping forming forge piece of step D is punched out according to the needs of forging；
F, trimming: the forging in step E is put into shaving die, cuts off extra overlap, and thrust wheel side cover can be obtained,
Finally wait natural cooling, outbound.
Further, rod iron of the present invention uses the rod iron of round rod iron, rectangular rod iron or irregular shape.
Compared with prior art, the invention has the following advantages:
1, the present invention is put into special die by forging machine punch forming using forge piece, greatly improves production efficiency, not only very
Defect existing for the good existing casting technique of solution, and forging plays the role of refining metal grain, and intensity is higher than casting, makes to produce
Product more adapt to varying environment use.
2, the present invention is better than gravity foundry technology using forging technology, later process is substantially improved, to make on product
More high-end market is walked, and this process implementing is easy, processing efficiency is higher.
Specific embodiment
Below with reference to embodiment, the invention will be further described, and mode of the invention includes but are not limited to following implementation
Example.
A kind of production technology of thrust wheel side cover, comprising the following steps:
A, blanking: the size of processing thrust wheel side cover required for selection carries out the outer diameter of selected rod iron, then with will with cutting machine
Rod iron cuts into several segments and can be carried out cutting into multistage according to rod iron length, to meet entire technique when rod iron is cut
Orderly carry out；
B, it heats: by the several segments round steel bar after step A cutting, being sent by conveyer belt in stove and several segments round steel bar is carried out
Heating, stove temperature are controlled at 1150 DEG C, until the surface of round steel bar dark red state occurs and can enter next process；
C, preliminary moulding: the aglow round steel bar after step B processing is put into pneumatic hammer and carries out preliminary moulding, this preliminary moulding can
To meet the molding processing request of postorder main mould；
D, main mould forms: the round steel bar after moulding preliminary in step C being put into the mold cavity of forging machine, forging machine is to round steel
Stick carries out punch forming；
E, it machines: the stamping forming forge piece of step D is punched out according to the needs of casting；
F, trimming: the forging in step E is put into shaving die, cuts off extra overlap, and thrust wheel side cover can be obtained,
Finally wait natural cooling, outbound.
Above-described embodiment is only the preferred embodiment of the present invention, should not be taken to limit protection scope of the present invention, but
It is all in body design thought of the invention and mentally make have no the change of essential meaning or polishing, the technology solved
Problem is still consistent with the present invention, should all be included within protection scope of the present invention.
