Abstract
The utility model discloses a truing crown of a heat treating bearing ring, which consists of a forcer (1), a post rod (2) and a regulating stem (3), the forcer (1) and the regulating stem (3) are respectively connected with the two ends of the post rod (2). The utility model has the advantages of novel conception, simple structure and convenient usage. The heat treating bearing ring is reshaped through the adjustable truing crown, changing the original method of reshaping the bearing ring distortion produced after the heat treating heat hardening of the bearing ring by slapping with a bar copper into the reshaping method of topping at the inner part of the bearing ring, thus ensuring the steadiness of the performance of the heat treating bearing ring, and greatly reducing the defective index caused by the distortion of the product. The waste product caused by distortion, the energy consumption and the labour intensity are reduced.
Description
Described field
The utility model belongs to the shaping technique field of bearing ring, and what relate generally to is a kind of heat treatment bearing ring 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
The purpose of this utility model promptly produces thus, proposes a kind of heat treatment bearing ring shaping holder.Use this shaping holder that bearing ring is carried out the stability that shaping can be guaranteed the bearing ring performance, the rate of reducing the number of rejects and seconds reduces labor intensity.
For achieving the above object, the technical scheme that the utility model is taked is: it 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 utility model 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, 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 the utility model structural representation
Fig. 2 is the utility model user mode schematic diagram
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 embodiment of the present utility model:
As shown in Figure 1: present embodiment 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 (as shown in Figure 2); 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.
