Abstract
The utility model relates to a flat punch with a reinforcing sleeve, which comprises a punch body and the reinforcing sleeve, wherein the upper part of the punch body is embedded in the long hole in the reinforcing sleeve; the lower part of the punch body is positioned at the external part of the lower end face of the reinforcing sleeve; the reinforcing sleeve is composed of two symmetrical straight surfaces and two symmetrical cambered surfaces in outline structure. According to the flat punch provided by the utility model, the reinforcing sleeve is mounted at the external part of the flat punch, and during the punching process, the reinforcing sleeve can protect and reinforce the flat punch, so that the rigidity of the flat long high punch is improved, and the service life of the punch is prolonged effectively; in addition, the upper part and the lower part of the punch are the same in structure and consistent in size, so that a linear cutting processing mode can be used, and the processing cost of the punch is reduced; the flat punch is simple in structure and scientific and reasonable in design, the punch is convenient to process, the processing cost is reduced, and the service life of the punch is prolonged.
Description
Technical field
The utility model belongs to cold punching die technical field, relates to drift, especially a kind of flat drift with reinforcing sleeve.
Background technology
In cold punching die, drift is crucial consumable accessory, especially special-shaped flat drift (prolate and height), and the non-constant of its rigidity, fragile.
In prior art, the structure of flat drift as shown in Figure 1 and Figure 2, formed by punch body 2 and installing handle 1, described punch body and installing handle one are made, this installing handle is made up of two symmetrical facing directly with two symmetrical arcwall faces, and object is to be convenient to be installed together with punch fixing plate (place not shown in the figures).
Because the flat drift of this abnormity must use Digit Control Machine Tool processing, thereby greatly improve the cost of drift.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of flat drift with reinforcing sleeve is provided, and the drift in this structure uses line cutting to process, thereby has greatly reduced the processing cost of drift.
Scheme of the present utility model is achieved in that
With a flat drift for reinforcing sleeve, comprise drift and reinforcing sleeve, the top of described drift is inlaid in the slotted hole that reinforcing sleeve is shaped with, and the bottom of this drift is positioned at the outside, lower surface of reinforcing sleeve.
And the contour structures of described reinforcing sleeve is made up of two symmetrical facing directly with two symmetrical arcwall faces.
And the top of described drift is identical with the structure of lower portion of ram and in the same size.
Advantage of the present utility model and good effect are:
Flat drift in the utility model is by its outside, reinforcing sleeve being installed, and in the process of punching press, reinforcing sleeve plays to flat drift the effect that protection is reinforced, and has not only improved prolate and the rigidity of high drift, the use that has effectively extended drift; In addition, the upper and lower part structure of drift is identical and in the same size, thereby can use the processing mode of line cutting, reduces the processing cost of drift.The utility model is simple in structure, design science is reasonable, and drift is easy to process, has reduced processing cost, and has extended the service life of drift.
Brief description of the drawings
Fig. 1 is the front view of prior art drift;
Fig. 2 is the bottom view of Fig. 1;
Fig. 3 is the structural front view of drift of the present utility model and reinforcing sleeve;
Fig. 4 is the upward view of Fig. 3.
Detailed description of the invention
Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.
With a flat drift for reinforcing sleeve, as shown in Figure 3, Figure 4, comprise drift 4 and reinforcing sleeve 3, the top of described drift is inlaid in the slotted hole that reinforcing sleeve is shaped with, and the bottom of this drift is positioned at the outside, lower surface of reinforcing sleeve.
In the present embodiment, the contour structures of described reinforcing sleeve is made up of two symmetrical facing directly with two symmetrical arcwall faces, thereby is convenient to be connected with punch fixing plate (not shown).
The top (being installing handle) of described drift is identical and in the same size with the structure of lower portion of ram (being punch body), therefore can use the processing mode that adopts line cutting, effectively reduces the processing cost of drift.
Flat drift in the utility model is by its outside, reinforcing sleeve being installed, and in the process of punching press, reinforcing sleeve plays to flat drift the effect that protection is reinforced, and has not only improved prolate and the rigidity of high drift, the use that has effectively extended drift; In addition, the upper and lower part structure of drift is identical and in the same size, thereby can use the processing mode of line cutting, reduces the processing cost of drift.The utility model is simple in structure, design science is reasonable, and drift is easy to process, has reduced processing cost, and has extended the service life of drift.
It is emphasized that; embodiment described in the utility model is illustrative; instead of determinate; therefore the utility model comprises and is not limited to the embodiment described in detailed description of the invention; every other embodiments that drawn according to the technical solution of the utility model by those skilled in the art, belong to the scope that the utility model is protected equally.
Claims (3)
