Specific embodiment
The utility model is further illustrated below by the mode of embodiment, but be not therefore limited in the utility model
Among the embodiment described range.
As shown in Figs. 1-2, mold includes：Upper mold 10 and lower die 30, the shape of the bottom surface of upper mold 10 is arc-shaped, lower die 30
The shape of top surface and the bottom surface of upper mold 10 match, the radius of curvature at the middle part 11 of the bottom surface of upper mold 10, which is more than, is located at middle part 11
The radius of curvature of two sides part 12 of both sides, lower die 30 are provided with several heating tubes 20, and heating tube 20 runs through lower die 30.On
The bottom surface of mould 10 for arc-shaped and lower die 30 top surface shape it is matching be to meet processing tungsten alloy radian plate 60
Needs, the radius of curvature at the middle part 11 of upper mold 10 is identical with the radius of curvature of tungsten alloy radian plate 60 to complete, two
The radius of curvature of side part 12 is slightly less than the radius of curvature at middle part 11.When carrying out punch process to tungsten alloy radian plate 60, due to
Its rigidity is stronger, can generate certain rebound, and the radius of curvature of two sides part 12 is less than the design of the radius of curvature at middle part 11
It can solve the problems, such as that tungsten alloy radian plate 60 is sprung back in processing.Lower die 30 is designed with heating tube 20, and heating tube 20 runs through
Lower die 30 is in order to which lower die 30 is enable to heat tungsten alloy radian plate 60, in existing processing technology, to tungsten alloy arc
The processing temperature of degree plate 60 will reach 800-900 degrees Celsius, and reaching this temperature can only realize in heating furnace, and use the dress
Putting only needs lower die 30 being worked into 300-400 degrees Celsius, then coordinates the design of the radian of middle part 11 and two sides part 12, with regard to energy
It realizes the processing effect that original high temperature can be only achieved, also, can not need to operate in heating furnace using the device, significantly
Processing cost is saved, improves processing efficiency.
Distance of the heating tube 20 apart from the top surface of lower die 30 is 20mm-40mm.Heating tube 20 to lower die 30 top surface away from
From be by experiment repeatedly obtain as a result, keeping with a distance from this on the one hand to make lower die 30 heated rapidly, on the other hand
Avoid the structural stability that lower die 30 is influenced through lower die 30 due to heating tube 20.
Heating tube 20 is uniformly arranged in lower die 30.Also, the quantity of heating tube 20 is 8-15.The quantity of heating tube 20
It is also by obtained by experiment repeatedly, certainly, the quantity of heating tube 20 is more, the speed that lower die 30 heats will be faster, still,
Excessive heating tube 20 can improve the manufacture cost of mold, and the heating speed of the heating tube 20 of this quantity does not interfere with
Normal to use, heating tube 20 is uniformly arranged also for lower die 30 is enable to be evenly heated, the temperature phase of entire lower die 30
Together, so as to obtaining better processing effect.
Middle part 11 is equal with the arc length of side part 12.Also, the radius of curvature at middle part 11 be 170mm, two sides part 12
Radius of curvature be 148.5mm.The arc length of middle part 11 and two sides part 12 is equal and the curvature of middle part 11 and side part 12
The The concrete specification of radius is summarized by repetition test, can preferably solve returning after tungsten alloy radian plate 60 is processed
Bullet problem.
Mold further includes hydraulic press, and a part for hydraulic press is only illustrated in figure.Hydraulic press includes hydraulic stem 40 and pedestal
Platform 50, hydraulic stem 40 move on the direction close to and far from base platform 50, and upper mold 10 is connected to hydraulic stem 40, lower die
30 are fixed on base platform 50.In process, upper mold 10 and lower die 30 will be under the cooperations of hydraulic press to tungsten alloy radian plate
60 are operated, and hydraulic stem 40 connects upper mold 10 and moved, and lower die 30 is fixed on base platform 50.
