Abstract
The utility model relates to a wrist-arm hardware fitting base forging mould for parts of an electrified railway contact network. The mould comprises an upper mould and a lower mould; the cavities of the upper and lower moulds are combined to form the cavity of a hardware fitting base; the cavity comprises a base and ear parts symmetrically arranged at the two sides; the taper of the middle part of the inner side surface of the ear part of the cavity is 1-2 degrees; and the inner wall of the cavity is provided with an exhaust channel communicated with the outside. When the hardware fitting base is forged, the lower mould is mounted on the worktable of a friction press, the upper mould is mounted on a slider, and the upper and lower moulds are combined through the slider so as to extrude the forging material to form the hardware fitting base. As the exhaust channel is formed on the inner wall of the cavity, punching is easier, the tonnage of the friction press is greatly reduced, the friction press is not easily discarded, and the manufacturing cost is remarkably lowered. Moreover, due to the adoption of the exhaust channel, when the taper of the middle part of the inner side surface of the ear part of the cavity is 1-2 degrees, the mould can be easily drawn out, and the contact area between the two ear parts of the hardware fitting base and a connecting piece is increased when in assembly, thus the stress effect is good.
Description
Technical field
The utility model relates to a kind of forging mold, particularly a kind of electrification railway contact net parts bracket formula gold utensil forging base mould.
Background technology
Electrification railway contact net parts bracket formula gold utensil base is used for the connection of high speed electrification railway contact nets such as Beijing-Shanghai express railway, and its ear by base and bilateral symmetry setting thereof constitutes.The mode of producing this kind gold utensil base at present has two kinds: a kind of is the method that adopts casting, and it exists shortcoming to be: interior tissue is loose, and defectives such as shrinkage cavity, crackle are arranged, and can't meet the quality requirement, and has bigger potential safety hazard, and scraps more.
Can also adopt the method for forging, reason owing to mould structure, all enterprises are when adopting forging mold to forge this gold utensil base at present, the tonnage of the friction press that needs is quite big, even and adopt the large-tonnage friction press to forge, the gold utensil base that forges still is prone to towards the phenomenon of shape deficiency, cause scrapping of product, power consumption is high, and yield rate is low, and manufacturing cost is very high.
In addition, present gold utensil base mould is subjected to structural limitations, and the gold utensil chassis ears medial surface tapering that forges must be more than 3 °, otherwise can't withdrawing pattern, when it uses in the assembling of postorder product, cause another connector and gold utensil chassis ears contact area between two ears little, stressed effect is poor.
The utility model content
The technical problems to be solved in the utility model provides a kind of electrification railway contact net parts bracket formula gold utensil forging base mould, the stressed good and low cost of manufacture of the gold utensil base that forges.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of electrification railway contact net parts bracket formula gold utensil forging base mould, comprise upper die and lower die, the cavity combinations of described upper and lower mould forms the die cavity of this gold utensil base, described die cavity is made of the ear of base and bilateral symmetry setting thereof, and its innovative point is: the tapering at described die cavity ear medial surface middle part is 1-2 °; Be provided with the exhaust passage that is in communication with the outside at described die cavity inwall.
Further, described exhaust passage is located at the bottom of die cavity, and an end is communicated with die cavity, and the other end is in communication with the outside by the counterdie sidewall.
Advantage of the present utility model is: when carrying out the forging of gold utensil base, counterdie is installed on the workbench of friction press, patrix is installed on the slide block, will place in the counterdie through heating, the forging material clapped after flat, realizes by slide block that upper and lower mould matched moulds will be forged and expects to be squeezed into the gold utensil base.Since be provided with the exhaust passage at the die cavity inwall, easier in shape, greatly reducing the friction press tonnage, and be difficult for scrapping, manufacturing cost declines to a great extent.And because the setting of exhaust passage, when making the tapering at die cavity ear medial surface middle part be 1-2 °, withdrawing pattern smoothly, when increasing assembling gold utensil base ears partly with the contact area of connector, stressed effect is good.
And the exhaust passage is located at the bottom of die cavity, when die wear repairs a die, and can be not influenced because of the position of exhaust passage.
Description of drawings
Fig. 1 is the utility model electrification railway contact net parts bracket formula gold utensil forging base die cut view.
Fig. 2 is the counterdie vertical view of the utility model electrification railway contact net parts bracket formula gold utensil forging base mould.
The specific embodiment
As shown in Figure 1, 2, comprise patrix 1 and counterdie 2, the cavity combinations of this patrix 1 and counterdie 2 forms the die cavity 3 of gold utensil base, and described die cavity 3 is made of the 3b of ear of base 3a and bilateral symmetry setting thereof, and the tapering at this 3b of die cavity ear medial surface middle part is 1-2 °.
Inwall at die cavity 3 is provided with the exhaust passage 4 that is in communication with the outside, and this exhaust passage 4 is located at the bottom of die cavity 3, and an end is communicated with die cavity 3, and the other end extends to sidepiece to counterdie 2 lower surfaces vertically downward again, and the sidewall by counterdie 2 is in communication with the outside.When forging, owing in die cavity 3, be provided with exhaust passage 4, make that the air in the die cavity 3 are discharged, easier in shape, and at draft withdrawing pattern smoothly hour still.
Claims (2)
1. electrification railway contact net parts bracket formula gold utensil forging base mould, comprise upper die and lower die, the cavity combinations of described upper and lower mould forms the die cavity of this gold utensil base, described die cavity is made of the ear of base and bilateral symmetry setting thereof, it is characterized in that: the tapering at described die cavity ear medial surface middle part is 1-2 °; Be provided with the exhaust passage that is in communication with the outside at described die cavity inwall.
2. electrification railway contact net parts bracket formula gold utensil forging base mould according to claim 1, it is characterized in that: described exhaust passage is located at the bottom of die cavity, and an end is communicated with die cavity, and the other end is in communication with the outside by the counterdie sidewall.
