Abstract
The utility model provides a sealing ring machining mould. The sealing ring machining mould is provided with a big cylinder body and a small cylinder body which are coaxial and integrally molded, wherein the diameter of the bottom face of the big cylinder body is larger than the transversal external diameter of a to-be-processed workpiece, the diameter of the bottom face of the small cylinder body is slightly smaller than the transversal inner diameter of the to-be-processed workpiece, and a gap is formed between the small cylinder body and the to-be-processed workpiece. The step surface at the connecting position of the big cylinder body and the small cylinder body is a smooth plane and used for supporting the end heads of the to-be-processed workpiece. A fixing through hole which is matched with a machine tool tailstock centre is formed in the axial center of the mould. The sealing ring machining mould has the advantages of being high in rate of finished products, high in efficiency, safe, low in labor intensity and capable of being widely applied in machining of a sealing ring, and the sealing ring machining mould is a novel product which has a promotional value.
Description
Technical field
The utility model belongs to mechanical field, specifically relates to a kind of machining mould.
Background technology
Often relate to the manufacturing processing of sealing ring in the special equipment manufacturing industry, the sealing ring of this special use belongs to non-standard component because instructions for use is special, needs special-purpose machining mould to process.According to sealing ring actual techniques condition, processing large sealing loops member as shown in Figure 1, must select the large scale computer lathe for machining, because the seal ring material relative stiffness is poor, thickness of workpiece is thin, as according to the normality machined, can't obtain sealing ring workpiece complete in the designing requirement, must design special-purpose machining mould, guarantee in the process, the sealing ring that cuts down both met design requirement, and guaranteed not produce again plastic deformation, avoid simultaneously because sealing ring is larger, fly out and the staff is damaged in cutting and separating moment.
Summary of the invention
The defective that the utility model exists in order to solve prior art, design special fixedly mold, guarantee lathe in pipe profile processing, working angles, the sealing ring profiled member of processing, cutting down does not produce torsional deformation, guarantees in addition operating personnel's personal safety.According to the seal size, can utilize this mold that heavy caliber pipe is carried out machining, the disposable main equipment sealing gasket that meets design requirement that processes.
The technical solution of the utility model is:
The large and small coaxial clyinder that the sealing ring machining mould is formed in one, wherein the bottom surface diameter of large cylinder is greater than to be processed transversal external diameter; The bottom surface diameter of small cylinder is slightly less than to be processed transversal internal diameter, with to be processed formation gap; The step surface at large and small cylinder connection place is smooth flat, is used for supporting to be processed termination, has the fixed via that cooperates with the tailstock tool thimble in the axial centre of mold.
Wherein the bottom surface diameter preferred size of large cylinder is than to be processed the large 0.5-2cm of transversal external diameter; The gap of small cylinder and to be processed transversal internal diameter formation is preferably 1-2mm; The material of described mold is preferably wooden.
The utlity model has yield rate high, efficient is high, and safety, the characteristics that labour intensity is low can be widely used in the processing of sealing ring, is a kind of new product with promotional value.The mold that the utility model provides can guarantee to be processed nonvoluntary yaw in the working angles, the diameter dimension of mold small cylinder is less than to be processed internal diameter size, with to be processed the gap that the inwall maintenance is certain, this structure has guaranteed that sealing ring after separating from the cylindrical shell is unlikely out of hand and fly out, and also avoids lathe tool at the eleventh hour the sealing ring that machines to be caused external force deformation simultaneously.
Description of drawings
Fig. 1 is sealing ring finished product schematic diagram;
Fig. 2 is that the utility model is used schematic diagram;
Fig. 3 is the utility model structural representation;
Wherein, 1, lathe chuck, 2, to be processed, 3, the sealing ring machining mould, 4, barrel of tail stock, 5, lathe tool, 6 tailstock centers.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is illustrated:
Adopt the lathe chuck 1 of 2.5 meters lathes of processing diameter, to be processed 2 of 2 meters of transversal external diameters of clamping, tailstock center 6 at the barrel of tail stock 4 of to be processed the other end is installed sealing ring machining moulds 3, the concrete shape of mold 3 as shown in Figure 3, choosing wood materials makes, the large and small coaxial clyinder that is structure as a whole, wherein the bottom surface diameter dimension of large cylinder is 2.02 meters; Small cylinder and to be processed 2 have formed the gap, and the gap is 2mm, and be unlikely out of hand and fly out to guarantee sealing ring after separating from the cylindrical shell, also avoids at the eleventh hour the sealing ring that machines being caused external force deformation simultaneously.The step surface at large and small cylinder connection place is smooth flat, is used for supporting to be processed 2 termination, has the fixed via that cooperates with tailstock tool thimble 6 in the axial centre of mold.
Mold outside dimension radially table top contacts with to be processed material end, to guarantee supporting to be processed nonvoluntary yaw in the working angles, then starts lathe.Use lathe tool to process first to machined part the whole appearance and size of the sealing ring of designing requirement, then on the position of designing requirement, cut the complete seal packing ring of lower designing requirement.
