Problems solved by technology

[0002] The traditional tungsten carbide drawing die has only one station, and each drawing can only complete the drawing of one product, which leads to low production efficiency, high labor intensity of employees, and high production cost
And in the drawing process, due to the overall processing and forming of the mold, it is easy to cause wear under the huge friction force of the drawing forming, which makes the service life of the mold shorter, and the cost of cemented carbide materials is high, which is not conducive to the market.

Embodiment Construction

[0013] The present invention will be described in further detail in conjunction with the accompanying drawings and specific embodiments.

[0014] Such as figure 1 As shown, the cemented carbide mold of the present invention includes an upper mold 7, a lower mold 5 and several mold cores. Wherein the upper mold 7 and the lower mold 5 are both made of chrome steel material, and the upper mold 7 and the lower mold 5 can be stretched relatively. The mold core is composed of an upper molding cavity 1 positioned at the upper mold 7 , a necking cavity 3 positioned at the lower mold 5 , and a lower molding cavity 4 . The core of the lower mold includes a necking cavity and a lower molding cavity, wherein the necking cavity 3 is trapezoidal, the upper side is consistent with the caliber of the upper molding cavity 1, and the lower side is consistent with the caliber of the lower molding cavity 4. The necking cavity can be used to make the The stretched workpiece is gradually stretche...

Abstract

The invention discloses a hard alloy die, which comprises an upper die, a lower die and a plurality of die cores, wherein the upper die and the lower die can be oppositely stretched; each die core is composed of an upper molding cavity in the upper die, a necking-down cavity in the lower die and a lower molding cavity; guide posts are arranged on the positions of the upper die, on two sides of each mold core; and guide grooves are formed in the corresponding upper die. By the plurality of die cores, the drawing efficiency can be improved; through cooperation of the guide posts and the guide grooves, the upper die and the lower die can be stretched along a straight line; the stretching accuracy is improved; in addition, a layer of hard alloy layer is arranged in the die made of a chrome steel material, so that the cost of the die is reduced; and the service life of the die is relatively long.

Description

technical field [0001] The invention discloses a cemented carbide mold, which belongs to the technical field of hardware processing. Background technique [0002] The traditional tungsten carbide drawing die has only one station, and each drawing can only complete the drawing of one product, which leads to low production efficiency, high labor intensity for employees, and high production costs. And in the drawing process, due to the overall processing and forming of the mold, it is easy to cause wear under the huge friction force of the drawing forming, which makes the service life of the mold shorter, and the cost of cemented carbide materials is high, which is not conducive to the market. Promote apps. Therefore, there is an urgent need for a cemented carbide mold with an improved structure. Contents of the invention [0003] The object of the present invention is to provide a multi-station cemented carbide mold with low use cost and high production efficiency. [000...
