Abstract
The utility model discloses a blind hole plunger chip sleeve. The blind hole plunger chip sleeve comprise a head and a body which stretches from the axis of the head, wherein the head is a sealed surface; the inner side face of the body is divided into a threaded part and a thread-free part; the body comprises a large-diameter part and a small-diameter part; the large-diameter part is provided with the threaded part; the small-diameter part is provided with the threaded part and the thread-free part which outwards stretches from the threaded part; two concave platform parts which are arranged in parallel are also arranged on the outer side face of the small-diameter part; an arc-shaped groove is formed in the inner surface of the head. Due to the adoption of the structural design, when the blind hole plunger chip sleeve is matched with a plunger chip for use, the abrasive resistance is good, the service lift is longer, the abrasion speed of the plunger chip is effectively reduced, the service life of the plunger chip is prolonged, and the quality of processing a workpiece is ensured.
Description
Technical field
The utility model relates to a kind of mold and punching head, and specifically, it is a kind of blind hole drift cover.
Background technology
In mould, drift is a kind of metal parts being arranged on die casting, and drift cover is the part being slidably connected with steel core.
Drift cover in the past, for cylinder, is axially provided with through hole, and described through-hole wall face is provided with a stepped step, and the through hole of this stepped step top pumps for drift.Because drift jacket wall degree is thicker, length is short, and drift is in drift cover when prolonged exercise, and the rate of wear of drift is very fast, and the life-span is shorter, can not ensure the quality of processing work, can not meet modern society and the client more and more higher requirement of headgear that liquidates.
Therefore, prior art needs to be improved and improves.
Summary of the invention
For overcoming the problems referred to above of the prior art, the purpose of this utility model is to provide one can reduce the drift rate of wear, extends drift service life, ensures the blind hole drift cover of processing work quality.
The utility model is to realize above-mentioned purpose by following technological means:
A kind of blind hole drift cover, comprises a head and a body portion of extending from head axes, and wherein head is sealing surface, and body portion medial surface is for having threaded portion and unthreaded portion; Described body portion comprises large-diameter portion and minor diameter part, and described large-diameter portion has threaded portion, and described minor diameter part has threaded portion and the unthreaded portion from there being threaded portion to stretch out away, and the lateral surface of described minor diameter part is also provided with the two concave station portions that be arranged in parallel; The inner surface of described head is provided with an arc groove.
Compared with prior art, the beneficial effects of the utility model are: owing to adopting above-mentioned structural design, in the time that the utility model and drift are used in combination, not only wearability is good, and service life is poor, can effectively reduce the rate of wear of drift, thereby extend the service life of drift, ensure the quality of processing work.
Brief description of the drawings
Accompanying drawing 1 is cross-sectional view of the present utility model.
In figure, each label is respectively: (1) head, and (2) body portion, (3) large-diameter portion, (4) minor diameter part, (5) have threaded portion, (6) unthreaded portion, (7) concave station portion, (8) arc groove.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Referring to Fig. 1, a kind of blind hole drift of the utility model cover, comprises a head 1 and a body portion 2 from head 1 Axis Extension, and wherein head 1 is sealing surface, and body portion 2 medial surfaces are for having threaded portion 5 and unthreaded portion 6; Described body portion 2 comprises large-diameter portion 3 and minor diameter part 4, described large-diameter portion 3 has threaded portion 5, described minor diameter part 4 has threaded portion 5 and the unthreaded portion 6 from there being threaded portion 5 to stretch out away, and the lateral surface of described minor diameter part 4 is also provided with the two concave station portions 7 that be arranged in parallel; The inner surface of described head 1 is provided with an arc groove 8.
The utility model matches with specific drift, is installed on die casting grinding tool, not only can make the rate of wear of drift reduce, and extends the service life of drift, and then ensures the quality of processing work, has market value and huge market potential widely.
The above, only better enforcement of the present utility model, not the utility model is done to any pro forma restriction, any those skilled in the art may utilize above-mentioned technology contents to be changed or be modified to the equivalent embodiment of equivalent variations, at this, all the technical solution of the utility model contents that do not depart from, any simple modification, equivalent variations and the modification just according to technical spirit of the present utility model, above embodiment done, all still belong in the scope of technical solutions of the utility model.
