Abstract
The utility model discloses a firing pin structure used for a wellhead connector, which comprises a pinpoint (2) and a pin body (1), wherein a press-jointing hole (3) is arranged on the pin body (1) and connected with a vent hole (4), and the pinpoint (2) is inserted into the press-jointing hole (3). As the firing pin structure adopts the technical scheme, the pinpoint has simple appearance, high hardness and simple processing, can be directly ground and molded after being quenched and has no stress concentration point, the pin body has low hardness and easy processing, the manufactured firing pin has no stress concentration at the combination part between the pinpoint and the pin body, and the pinpoint can not be broken. The utility model fully gives consideration to both the processing performance and the using performance and ensures the working reliability of the firing pin under the situation of reducing the processing difficulty. Compared with the prior art, the utility model has the advantages of simple processing, low production cost, reliable use, and the like.
Description
Technical field
The utility model relates to the striker structure that a kind of wellhead connector uses, and belongs to oil field shaft mouth connector technique field.
Background technology
The oil field is used for the wellhead connector of well depth test, as long as employing sound bullet as sound source, just must use striker.Present striker is the integrated design, and for processing request and the percussion wear-resisting requirement in position of satisfying the striker main body, selects for use the martensite type stainless steel as the striker material usually.Its major defect has 2 points: the one, and differential hardening processing cost height; The 2nd, tangible size sudden change is arranged between striker main body and the percussion position, sudden change place because stress is concentrated, causes fracture easily.
Summary of the invention
The purpose of this utility model is: provide that a kind of cost is low, processing is simple, the striker structure for wellhead connector of reliable operation, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: striker structure for wellhead connector, and structure comprises needle point and needle body, is provided with the crimping hole on needle body, and the crimping hole connects steam vent, and needle point inserts in the crimping hole.
Above-mentioned striker structure for wellhead connector, the crimping hole is greater than the diameter of steam vent.
Above-mentioned striker structure for wellhead connector, the hardness of needle point material is greater than the hardness of needle body material.
Above-mentioned striker structure for wellhead connector, needle surface is smooth.
Above-mentioned striker structure for wellhead connector, the crimping hole of needle point and needle body is an interference fit.
Owing to adopted technique scheme, needle point profile of the present utility model is simple, can be after quenching direct grinding-shaping, the hardness height, processing is simple, unstressed centrostigma.Needle body hardness is low, handling ease, and the striker of making, unstressed the concentrating in both junctions, needle point can not rupture.The utility model has fully been taken into account processing characteristics and functional performance, has guaranteed the functional reliability of striker under the situation that reduces difficulty of processing.Compare with prior art, the utlity model has advantages such as processing is simple, cost of production is low, use is reliable.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the structural representation of the utility model needle body.
The specific embodiment
Embodiment of the present utility model: make needle point 2 and needle body 1 respectively, produce crimping hole 3 on needle body 1, crimping hole 3 connects steam vent 4, and needle point 2 is inserted in the crimping hole 3, obtains striker.
Direct grinding-shaping after needle point 2 adopts the rolling bearing steel to quench, smooth surface, the hardness height, processing is simple, unstressed centrostigma.Make the hardness of the hardness of needle point 2 materials greater than needle body 1 material, needle body 1 hardness is low, handling ease.
Crimping hole 3 should be greater than the diameter of steam vent 4.For fixing firm, needle point 2 is an interference fit with the crimping hole 3 of needle body 1.
Claims (5)
1. striker structure for wellhead connector is characterized in that: structure comprises needle point (2) and needle body (1), is provided with crimping hole (3) on needle body (1), and crimping hole (3) connect steam vent (4), in needle point (2) the insertion crimping hole (3).
2. striker structure for wellhead connector according to claim 1 is characterized in that: crimping hole (3) are greater than the diameter of steam vent (4).
