Abstract
The utility model relates to a processing die for an oil seal bolt, which is characterized in that the main bodies are a first alloy block, a second alloy block, a third alloy block and a fourth alloy block, wherein the first alloy block and the second alloy block are matched for use, a boss is arranged at the inner side of the first alloy block and the second alloy block, and the boss is narrow at the lower part and wide at the upper part; and the third alloy block and the fourth alloy block are matched for use and are threaded processing dies, and a thin board is embedded in the inner side of the third alloy block. The design of the structure is applied in automation equipment, the processing die can effectively reduce the deformation of a seal groove of the oil seal bolt caused by lathe processing, meanwhile, the work efficiency is improved, and the uniformity of product sizes is ensured.
Description
Technical field
The utility model relates to a kind of frock clamp, especially relates to the indeformable oil sealing bolt of a kind of assurance working groove processing mold.
Background technology
Oil sealing bolt 8 as shown in Figure 3, bolt shank have a groove of putting O type circle, and the O type encloses sealing function, and common this bolt is called oil sealing bolt 8; Header bolt blank normally in conventional production process, lathe grinding bar portion groove, thread-rolling screw can be found out from above-mentioned technology again, mainly processes intensity at cutting process, product size receives the influence of people and cutter bigger; After processing seal groove, during thread-rolling screw, because thread-rolling screw can cause the distortion of O type ring recess, influence the assembling of O type circle again, cause clamping once more correction seal groove size, working (machining) efficiency is very low.
Summary of the invention
The utility model technical problem to be solved provides a kind of oil sealing bolt processing mold of avoiding crimp, increasing work efficiency.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of oil sealing bolt processing mold; Main body is first alloy block, second alloy block, the 3rd alloy block and the 4th alloy block; Wherein, Said first alloy block and second alloy block are used, and are provided with a boss in the inboard of first alloy block and second alloy block; Said the 3rd alloy block and the 4th alloy block are used, and offer screw thread processing teeth groove in the inboard of the 3rd alloy block and the 4th alloy block.
Meet size, indeformable in order to guarantee that oil sealing bolt seals groove is processed, on the direction of first alloy block of said boss edge, from low to high, from narrow to wide.
Guarantee that screw thread is indeformable when guaranteeing the screw thread on the extrusion process bolt, said the 3rd alloy block inboard is bumped into a thin plate, or said the 4th alloy block inboard is bumped into a thin plate.
After adopting said structure, be characterized in: this structural design is applied on the automation equipment, can effectively reduce the oil sealing bolt because the seal groove distortion that machined into causes has improved operating efficiency simultaneously, has guaranteed the uniformity of product size.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the mould sketch map of the crush seal groove of the utility model;
Fig. 2 is the mould sketch map of the thread-rolling screw of the utility model;
Fig. 3 is an oil sealing bolt sketch map.
Among the figure: 1, first alloy block 2, second alloy block 3, the 3rd alloy block 4, the 4th alloy block 5, boss 6, screw thread processing teeth groove 7, thin plate 8, oil sealing bolt.
The specific embodiment
Fig. 1, a kind of oil sealing bolt processing mold shown in Figure 2; Main body is first alloy block 1, second alloy block 2, the 3rd alloy block 3 and the 4th alloy block 4; Wherein, said first alloy block 1 and second alloy block 2 are used, and are provided with a boss 5 in the inboard of first alloy block 1 and second alloy block 2; Said boss 5, from narrow to wide, guarantees that the processing of oil sealing bolt 8 seal grooves meets size from low to high along on the direction of first alloy block 1; Said the 3rd alloy block 3 and the 4th alloy block 4 are used, and offer screw thread processing teeth groove 6 in the inboard of the 3rd alloy block 3 and the 4th alloy block 4, and the effect of screw thread processing teeth groove 6 is to be used for the extrusion process screw thread; Unitary mould is through vacuum heat, and hardness reaches more than the HRc60, and the titanium carbide processing is carried out on the surface again, and die life is improved greatly, increases the fineness that is extruded the bolt position.
The 3rd alloy block shown in Figure 23 inboards are bumped into a thin plate 7, or the 4th alloy block 4 inboards are bumped into a thin plate 7, and when guaranteeing the screw thread on the extrusion process bolt, O type ring recess is indeformable.
This structural design is applied on the automation equipment; Can effectively reduce the oil sealing bolt because the seal groove that machined into causes is out of shape, and per minute production capacity can reach more than 60, be 100 times of lathe turning processing; Improve production efficiency greatly, also guaranteed the uniformity of product size.
Claims (4)
