Abstract
The utility model discloses a segmented mold for deep and long hole. The segmented mold comprises a mold core midpiece, mold core ports are arranged on the two ends of the mold core midpiece, grooves are arranged on the circumferential surfaces of the outer ends of the mold core ports, coaxial inner holes being same in size are arranged in the mold core ports and the inner part of the mold core midpiece, a mold core sleeve is welded on the outer surfaces of the mold core ports and the mold core midpiece, convex mold core blocking rings are arranged on the inner surfaces of the two ends of the mold core sleeve and are matched with the grooves on the circumferential surfaces of the outer ends of the mold core ports. According to the segmented mold for the deep and long hole, a long part is disassembled into short parts according to practical conditions, so that the processing is convenient, the concentricity of the excircles and the inner holes of the mold ports and the mold core midpiece is same, the surfaces of the inner holes can be easily processed to be smooth, the deep hole drifting is solved perfectly, and the technical requirement is met.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of deep and long hole segmented die.
Background technology
In the machining, the deep and long hole of some wire dies is mainly processed with depth drill now.Because deep hole is longer, is easy to generate drift with the depth drill deep hole processing, the concentricity of cylindrical and endoporus is reduced greatly, and linearity is low, inner bore surface roughness is low, so this deep hole mould can not satisfy the specification requirement of the high part of required precision.
Summary of the invention
The purpose of the utility model provides a kind of deep and long hole segmented die, and the cylindrical of mould is identical with the endoporus concentricity, linearity, surface roughness, accuracy height.
The technical scheme that the utility model adopted is that the deep and long hole segmented die comprises the core rod stage casing; The two ends in core rod stage casing are provided with the core rod port; The outer end periphery of core rod port is provided with groove, and intersegmental part has identical size and coaxial endoporus in core rod port and the core rod, and core rod port and core rod stage casing outer surface are welded with the core rod cover jointly; The two ends inner surface of core rod cover is provided with protruding core rod back-up ring, and the groove on core rod back-up ring and the core rod port outer end periphery is complementary.
The deep and long hole segmented die of the utility model; Elongated workpieces in the light of actual conditions is decomposed into short part; Be convenient to processing, and guarantee that easily the concentricity of cylindrical and endoporus in core rod port and core rod stage casing is identical, its bore area also is easy to process smooth; The phenomenon that perfection has solved the deep hole drift has satisfied specification requirement.
Description of drawings
Fig. 1 is the structural representation of the utility model deep and long hole segmented die.
Among the figure, 1. core rod port, 2. core rod stage casing, 3. core rod cover, 4. core rod back-up ring, 5. endoporus.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is elaborated.
The structure of the utility model deep and long hole segmented die, as shown in Figure 1, comprise more piece core rod stage casing 2, the two ends in core rod stage casing 2 are provided with the core rod port one, and the outer end periphery of core rod port one is provided with groove.Core rod port one and core rod stage casing 2 constitute the core rod of segmented; The core rod port one has identical size and coaxial endoporus 5 with 2 inside, core rod stage casing; Core rod port one and core rod stage casing 2 outer surfaces are welded with core rod cover 3 jointly; The two ends inner surface of core rod cover 3 is provided with protruding core rod back-up ring 4, and the groove on core rod back-up ring 4 and the core rod port one outer end periphery is complementary.
The utility model deep and long hole segmented die; Owing to existing mould parts is decomposed into the core rod of segmented; Elongated workpieces in the light of actual conditions is decomposed into short part; Be convenient to processing, and guarantee that easily the concentricity of cylindrical and endoporus in core rod port one and core rod stage casing 2 is identical, its bore area also is easy to process smooth.The core rod cover 3 that core rod port one, core rod stage casing 2 and outer surface are provided with has constituted the deep and long hole segmented die.Core rod cover 3 has promptly guaranteed whole uniformity, has also fixed core rod port one and core rod stage casing 2.Core rod back-up ring 4 is used for fixing core rod port one and core rod cover 3, makes more firm.Adopt this novel deep and long hole segmented die, the phenomenon that perfection has solved the deep hole drift has satisfied specification requirement.
