Description
Technical field
The invention discloses a kind of railway anticreeper manufacturing process, belong to hardware manufacturing field.
Background technology
Creeprail often causes rail gap uneven, and sleeper is crooked to wait circuit questions, very big to the destructiveness of track, when serious
Also entail dangers to traffic safety, it is therefore necessary to take effective measure to prevent from creeping.Anticreeper is fastening in rail foot, with to prevent
Only rail is with respect to a kind of important railway casting that sleeper is longitudinally creeped.
Railway anticreeper is mainly made of a kind of non-closed ring, currently, non-being closed for forming this of railway anticreeper
The production method of cyclization part is mainly：Casting, welding and forging.1, for casting, cast-internal dense structure degree phase
For forge it is poor, and often will appear sand holes, stomata, misrun, deformation the defects of problem, need secondary operation, in addition, casting
It makes and is also easy to produce more gaseous contamination, water pollution etc..2, for welding, it usually will appear undercut, overlap, recess and weldering
Deformation etc. is connect, sometimes also surface pores and face crack, the incomplete root penetration etc. of single welding.This will make certain of anticreeper
A little performances fall flat.3, for forging, processing method is excessively simple and crude at present, causes the anticreeper of production consistent
Property it is too poor, such anticreeper does not have to effective solution slide creeping problem on guide rail；It is flat and every time can only single-piece life
Production, operation number is more, low production efficiency, waste of manpower resource, and is directly forged using plate, and stock utilization is low,
Material cost increases.
Therefore, from the point of view of being currently used for the manufacturing technology of anticreeper, being badly in need of one kind can save labor and can guarantee
The manufacturing process of the consistency of product improves stock utilization to reduce production cost, improves production efficiency, simultaneously also
Make product that there is stable comprehensive performance.This will bring good economic benefit in railway casting production.
Invention content
The object of the invention aims to solve the problem that the manufacturing issue of railway anticreeper, realizes that the technical solution of foregoing invention is:

Finishing, final molding.
Further, forging and stamping for the first time are completed and enter next impression after bending, new base is sent into again in the first bending impression
Material, and so on, follow-up blank enters successively, and the part of bending is then caught up with to advance toward next impression, and bending three times is closely connected,
Complete all bending steps.
Further, include the following steps：
(1) take satisfactory plate by good blank under defined size and weight sawing machine；
(2) plate is heated by heating furnace, heating temperature section is 950-1200 DEG C, heating time 0.5-
3min；
(3) plate that step (2) is heated to malleable temperature is transported to the 63t punchings equipped with Bending Mould by transfer device
Forging and stamping are carried out in bed and bending, the forging and stamping are carried out at the same time with bending, are carried out altogether three times；
(4) blank after bending three times is put under 800t forcing presses and carries out final finishing, wherein mold temperature is preferred
Preheating, temperature range are 180-300 DEG C.
So far, railway anticreeper manufacturing process terminates.The present invention is not related to subsequent heat treatment process.
Further, bending or forging and stamping are completed in same progressive die three times.
Further, in step (3), the first time press forging after first time bending has to be bent at 6.
Further, in step (3), second of press forging after second of bending has to be bent at 7.
Further, in step (3), the third time press forging after third time bending has to be bent at 8.
Further, in step (3), mold temperature should be preheated first, and temperature range is 180-300 DEG C.
Further, further include following steps：
(1) forging and stamping for the first time are completed in the first bending impression with after bending, first time press forging enters the second bender
Thorax is sent into new blank in the first bending impression at this time；
(2) second of forging and stamping is completed in the second bending impression with after bending, second of press forging enters third bender
Thorax is sent into new blank, first time press forging is sent into the second bending impression at this time in the first bending impression；
(3) completed in third bending impression third time forging and stamping with after bending, complete a third time press forging, one the
Secondary press forging and a first time press forging.
Further, bending or forging and stamping are completed in same progressive die three times.
The invention further relates to a kind of railway anticreeper, the railway anticreeper made of manufacturing process as described above.
Compared with prior art, the beneficial effects of the invention are as follows：
1) this manufacturing process is manufactured using the method for forging and stamping, and is continuous during manufacture, therefore phase
For the non-closed ring that traditional casting and welding manufacture come out, the advantage for thering are forging and stamping to bring, toughness, tensile strength,
There is incomparable advantage in compression strength, manufacturing environment.
2) this manufacturing process is more automated compared to traditional forging technology in disposed of in its entirety using progressive die,
The manpower needed is less, and Continuous maching is more efficient.
3) this manufacturing process not only allows continuous production, and it is former easily can also to change manufacture according to actual conditions
Material, to adapt to the operation of the railway system under Different climate, can also easily dock follow-up process, improve the reliable of transmission of electricity
Property and economy, meet railway system's demand, can be used for the production of the non-closed ring of similar shape.
