Description
Technical field
The utility model relates to a kind of punch structure of powder metallurgy die.
Background technology
Powder metallurgy die for using many undershoots structure, especially, when a certain drift is non-circular structure, can produce asymmetric lateral pressure during product shaping.When if the radial envelope of drift is less than 180 °, excessive lateral pressure can make to produce very large frictional force between drift, even when the demoulding, drift is broken.In the process of the products such as actual production flange, drift is very high owing to breaking the ratio of scrapping, and has increased maintenance, the replacement cost of equipment.
Utility model content
Large in order to overcome between the drift of prior art frictional force, during the demoulding, easily break drift, the deficiency that the ratio of scrapping is higher, the utility model provides a kind of anti-wear lubricated punch structure of powder metallurgy die.
The utility model solves the technical scheme that its technical problem adopts:
A kind of anti-wear lubricated punch structure of powder metallurgy die, comprise the first stamping, and cooperation is inserted into the second stamping in the first stamping, the side of described the second stamping is provided with holddown groove, in holddown groove, be installed with sheet lubricating bearings, the lateral surface of described lubricating bearings protrudes from the side of the second stamping, and connects with the medial surface of the first stamping, is provided with the recess that holds lubricating fluid on the lateral surface of described lubricating bearings.
On the lateral surface of described lubricating bearings, be provided with a plurality of recesses.
Described recess linear isometry is arranged in rows, and on the lateral surface of lubricating bearings, oblique parallel is provided with multirow recess.
Described holddown groove is rectangular slot, and described lubricating bearings is cube rectangular with holddown groove adaptation, and the thickness of described lubricating bearings is greater than the degree of depth of holddown groove.
Described recess is circular recess.
Further, described recess is diameter 2mm, the circular recess of dark 0.2mm.
The face that described lubricating bearings is placed in holddown groove is smooth flat.
The beneficial effects of the utility model are: 1, between the drift of powder metallurgy die, increase lubricating bearings, on lubricating bearings, added the lubricating fluids such as butter, can reduce the friction between drift, thus the frictional force between drift while reducing mold releasability.2, by increasing lubricating bearings, can prevent that the situation of cold welding from appearring in two drifts when being shaped, reduce the knockout press between mould, protected drift.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structure top view of the present utility model;
Fig. 2 is the top view of the first stamping in the utility model;
Fig. 3 is the structural representation of the lubricating bearings in the utility model.
The specific embodiment
Referring to figs. 1 through Fig. 3, the anti-wear lubricated punch structure of a kind of powder metallurgy die of the present utility model, comprise the first stamping 1, and cooperation is inserted into the second stamping 2 in the first stamping 1, the side of described the second stamping 2 is provided with holddown groove 21, in holddown groove 21, be installed with sheet lubricating bearings 3, the lateral surface of described lubricating bearings 3 protrudes from the side of the second stamping 2, and connect with the medial surface of the first stamping 1, on the lateral surface of described lubricating bearings 3, be provided with the recess 31 that holds the lubricating fluids such as butter.The lateral surface of lubricating bearings 3 is working face, is slidably matched with the medial surface of the first stamping 1.
On the lateral surface of described lubricating bearings 3, be provided with a plurality of recesses 31.
Described recess 31 linear isometries are arranged in rows, and on the lateral surface of lubricating bearings 3, oblique parallel is provided with multirow recess 31.The distribution of lubricating fluid is comparatively balanced like this, during drift relative sliding, lubricating fluid can the lateral surface that be distributed in lubricating bearings 3 of relative equilibrium on, can, because of the relative sliding between drift, not cause the quick loss of lubricating fluid simultaneously.
In this specific embodiment, for the ease of the installation of lubricating bearings 3, fixing, described holddown groove 21 is rectangular slot, and described lubricating bearings 3 is cube rectangular with holddown groove 21 adaptations, and the thickness of described lubricating bearings 3 is greater than the degree of depth of holddown groove 21.
Described recess 31 is circular recess.Further, area is uniform 25 the diameter 2mm that have an appointment on the lubricating bearings 3 of 400 square millimeters, the circular recess of dark 0.2mm.Arrange like this, both can guarantee that recess 31 held a certain amount of lubricating fluid, can guarantee not affect again the structural strength of lubricating bearings 3.
The face that described lubricating bearings 3 is placed in holddown groove 21 is smooth flat.Like this, the smooth flat of lubricating bearings 3 is placed in holddown groove 21, is close to the bottom surface of holddown groove 21, installs, fixes more firm.
As other embodiments, recess 31 can be arranged to radial arranging or the circular groove of helical arrangement.Described recess 31 can also be arranged to shallow slot, and single shallow slot is arranged on the lateral surface of lubricating bearings 3 with helical form, or a plurality of shallow slot is with radial setting.As long as can reach, hold lubricating fluid, reduce the object of frictional force.
The material of lubricating bearings 3 is mainly brass, and its surface is the material that coefficient of friction is low, on lubricating bearings 3, has added the lubricating fluids such as butter, can reduce the friction between drift, thus the frictional force between drift while reducing mold releasability.By increasing lubricating bearings 3, can prevent that the situation of cold welding from appearring in two drifts when being shaped, reduce the knockout press between mould, protected drift.
In present stage, produce in the powder metallurgical technique of the products such as flange, the product that exists the radial envelope of drift to be less than 180 ° has accounted for more than 50%, the utility model has improved the frictional behaviour of drift, reduced the frictional force between mould, improve the service life of mould, can save mould manufacture, maintenance cost more than 30%.
Certainly, the utility model, except above-mentioned embodiment, can also have other structural distortion, and these equivalent technical solutions also should be within its protection domain.
