Abstract
The invention relates to a thermal bearing sheath shaping method and relative shaping lifter, wherein said shaping method comprises that: arranging adjustable shaper at the deformed low point in the bearing sheath, adjusting said shaper to expand the inner diameter; then annealing them together; cooling via air into room temperature, removing lifter; then annealing again. Said lifter is formed by lifting head (1), lifting rod (2) and adjusting rod (3); the head (1) and rod (3) are connected to two ends of rod (2). The invention has simple structure and easy operation. The invention can improve the stability of bearing sheath, and avoid crack, while its can reduce energy consumption.
Description
Described field
The invention belongs to the shaping technique field of bearing ring, what relate generally to is a kind of heat treatment bearing ring shaping method and shaping holder.
Background technology
In bearing industry, it is in order to obtain high strength, high rigidity, endurance life and wear-resistant working face, to adapt to its condition of work that bearing ring is heat-treated.Lasso will enter high-temperature heater and heats for this reason---Technology for Heating Processing processing.For guaranteeing product quality, also need to carry out hot shaping for yielding bearing ring.
In lasso heat treatment production process, hot shaping be utilize to quench the tissue of back lasso and stress labile state by applied stress to change the lasso deformation direction, the plastic deformation that simultaneous is small realizes.Traditional hot shaping methods carries out shaping when temperature is higher soon after ring quenching is come out of the stove, it is the peak that the operative employee measures distortion rapidly, whether measure bearing ring more one by one after knocking with copper rod then is out of shape, up to the specification requirement of satisfying inspection procedure specification, just can proceed heat treated next process, after the tempering of quenching, measure by the inspector again.But still the generation that can not avoid bearing ring to be out of shape, the bearing ring of distortion is only done over again, and dwindles phenomenon because the product after doing over again is prone to, thereby has strengthened the percent defective of product.Facts have proved,, adopt the mode of knocking to cause the bearing ring micro-flaw, so that influence performance though this shaping methods is simple and easy to do.In addition, this shaping methods also exists labour intensity big, yields poorly, energy consumption is big, the problem that percent defective is high.
Summary of the invention
Purpose of the present invention promptly produces thus, proposes a kind of heat treatment bearing ring shaping method and shaping holder.Use this method that bearing ring is carried out the stability that shaping can be guaranteed the bearing ring performance; The shaping holder that proposes not only reduces labor intensity, and has reduced percent defective, has saved power consumption.
The present invention realizes that the technical scheme that said method is taked is: need the enterolithic low spot of bearing ring of shaping to place adjustable reshaper after heat treatment; by regulating this reshaper it is strutted at lasso internal diameter direction place; then with together tempering of lasso; air cooling to room temperature is laid down holder after the tempering, once gets final product by the tempering of normalized tempering technology after shaping is finished again.
Shaping holder of the present invention is made of top, push rod and adjusting rod, and the two ends of push rod are connected with adjusting rod with the top respectively.
The present invention is novel, and is simple in structure, easy to use.It carries out shaping by adjustable shaping holder to the heat treatment bearing ring, the lasso that original bearing ring is produced behind heat-treatment quenching is out of shape the mode of knocking shaping with copper rod, change into holder and withstand on shaping mode in the bearing ring, thereby guaranteed the stability of heat treatment bearing ring performance, avoided adopting the mode of knocking to cause the drawback of bearing ring micro-flaw, product is declined to a great extent because of the percent defective that distortion is caused.Reduce the waste product that distortion causes, reduced energy consumption, alleviated labour intensity.
Description of drawings
Fig. 1 is a structural representation of the present invention
Fig. 2 is the schematic diagram of holder of the present invention
Among the figure: 1, top, 2, push rod, 3, adjusting rod, 4, lasso.
The specific embodiment
In conjunction with the accompanying drawings, it is as follows to provide embodiments of the invention:
As shown in Figure 1: present embodiment is to need the enterolithic low spot of bearing ring of shaping to place adjustable reshaper after heat treatment; by regulating this reshaper it is strutted at lasso internal diameter direction place; then with together tempering of lasso 4; air cooling to room temperature is laid down holder after the tempering, once gets final product by the tempering of normalized tempering technology after shaping is finished again.
As shown in Figure 2: the shaping holder is made of top 1, push rod 2 and adjusting rod 3, and top 1 and adjusting rod 3 are connected to the two ends of push rod 2.Top 1, adjusting rod 3 can adopt multiple with the connected mode of push rod 2: for large-sized bearing ring, operation can be established threaded connection hole at the two ends of push rod 2 for convenience, and top 1 and adjusting rod 3 are threaded with push rod 2 respectively; For undersized bearing ring, can establish threaded connection hole at an end of push rod 2, adjusting rod 3 is threaded with this threaded connection hole, establishes spliced eye at the other end of push rod 2, top 1 and this spliced eye socket connection.
Present embodiment in use; the lasso process is quenched after the tempering; the member measures when confirming the lasso of distortion is arranged on inspection; the shaping holder is placed on lasso 4 enterolithic low spots; by regulating push rod 2 and adjusting rod 3 top 1 is strutted at lasso internal diameter direction place, with together tempering of lasso 4, air cooling to room temperature is laid down holder after the tempering then; after shaping is finished again once by the tempering of normalized tempering technology, further to eliminate stress.
Claims (4)
1, a kind of heat treatment bearing ring shaping method; it is characterized in that: after heat treatment, need the enterolithic low spot of bearing ring of shaping to place adjustable reshaper; by regulating this reshaper it is strutted at lasso internal diameter direction place; then with together tempering of lasso; air cooling to room temperature is laid down holder after the tempering, once gets final product by the tempering of normalized tempering technology after shaping is finished again.
2, a kind of shaping holder of realizing the described heat treatment bearing ring shaping method of claim 1 is characterized in that: it is made of top (1), push rod (2) and adjusting rod (3), and top (1) and adjusting rod (3) are connected to the two ends of push rod (2).
