Abstract
The utility model relates to a die pressing tool of a sealing stud gasket. The die pressing tool comprises a gasket primary deformation assembly and a gasket secondary resilience assembly. The gasket primary deformation assembly comprises a pressing column male die and a base female die. The pressing column male die comprises a pressing rod and a conical pressing head. The base female die comprises a base, a conical hole and a concave table, wherein the conical hole is formed in the base, and the concave table is arranged on the base. A gasket is arranged in the concave table. The gasket secondary resilience assembly comprises an upper die sleeve, a semi-open upper die, a semi-open gasket die and a lower die base. The upper die sleeve drives the semi-open upper die to move downwards under the effect of force, the force is transferred to the upper end of the gasket, and secondary resilience of the gasket is achieved through force extrusion and limit of the lower end of the gasket in the lower die base. The die pressing tool enables the gasket to penetrate threads to keep the gap between the gasket and a stud polish rod to be 0.02-0.05 mm, and the tool is simple in structure and easy to machine.

Described pad secondary resilience assembly comprises Upper Die-sleeve 3, half-open patrix 4, half-open pad mould 5 and die shoe 6, described half-open patrix 4 comprises two the medium-sized cylindrical hole 41 and half small cylindrical openings 42 that connect successively, two medium-sized cylinder borehole jacks are contained on one end double-screw bolt of studs and are limited in Upper Die-sleeve 3, and two and half small cylindrical openings are sleeved on the polished rod of studs;
The other end double-screw bolt of studs is placed in die shoe, two half-open pad die sleeves are contained on the polished rod of studs and one end is supported in axial limiting on die shoe, horn mouth one end in contact of the other end of two half-open pad moulds and the pad being once out of shape, one end in contact of the other end of described pad and half-open patrix
Described Upper Die-sleeve moves down with half-open patrix under the effect of power, power is delivered to pad upper end simultaneously, spacing in die shoe of the extruding by power and pad lower end, however pad is pressed in die shoe concave station from flat, realize the secondary resilience of pad.
The utility model has advantages of:
1, tool structure of the present utility model is simple, easily processing.
2, the studs pad that utilizes the utility model frock to process, the closely sealed and periphery polishing of the tight silk in gap between pad and polished rod, clearance control obtains just right.

The specific embodiment
Seal a mold pressing frock for studs pad, comprise deformed component of pad and pad secondary resilience assembly, deformed component of pad comprises compression leg punch and base die,
As shown in Figure 2, compression leg punch 1 comprises depression bar 11 and is fixed on the conical indenter 12 of depression bar one end, conical indenter comprises that first other end of boring line segment 13 and the second cone line segment 14, the first cone line segments connecting is successively fixedly connected with depression bar, and the other end of the second cone line segment is flush end; The cone angle of the first cone line segment is 120 °, and the cone angle of the second cone line segment is 60 °;
As shown in Figure 3, base die 2 comprises base 21 and is arranged on cone tank 22 and the concave station on base, and pad is placed in concave station, as shown in Figure 12,13, conical indenter, through pad interstitial hole the laminating of the bellmouth on the effect lower bottom base die of power, makes pad that once distortion occur;
Pad secondary resilience assembly comprises Upper Die-sleeve 3, half-open patrix 4, half-open pad mould 5 and die shoe 6, and one end double-screw bolt of studs is positioned at half-open patrix,
