A hard alloy hydraulic product mold tooling

Abstract

The invention discloses a hard alloy hydraulic product mold tooling, comprising two vertical plates arranged opposite to left and right, a pressing table is fixedly connected between the two vertical plates, and the opposite sides of the two vertical plates are A lifting slot is opened, a fixing block is fixedly connected in the two lifting slots, a lifting plate is slidably connected in the two lifting slots and above the fixing block, and a threaded rod and a threaded rod are respectively penetrated through the two lifting plates. Slide the vertical rod, the upper and lower ends of the threaded rod are respectively rotatably connected with the corresponding fixing block and the inner top wall of the lifting groove, and the upper and lower ends of the sliding vertical rod are respectively fixedly connected with the corresponding fixing block and the inner top wall of the lifting groove, wherein A driving motor for driving the threaded rod to rotate is fixedly installed on the upper end of the vertical plate. The advantages are: the present invention can automatically carry out the continuous pressing of the cemented carbide, improve the working efficiency, and at the same time, the metal powder will not be scattered during the pressing, and the working environment is safe and tidy.

Description

technical field [0001] The invention relates to the technical field of cemented carbide hydraulic products, in particular to a mold tool for cemented carbide hydraulic products. Background technique [0002] Cemented carbide is an alloy material made of hard compound of refractory metal and bonding metal through powder metallurgy process. This process can process precision parts with high hardness, such as gears, cutting tools, etc. . In the processing of cemented carbide, it is necessary to use a hydraulic press to cooperate with a mold to press the alloy powder and then sinter it. The pressing effect of the alloy powder directly affects the quality of the alloy material. [0003] In the existing powder metallurgy process, the used mold tooling will accumulate metal powder around the mold slot in advance, and then use the push plate to automatically push the metal powder into the mold slot and smooth the slot. The metal powder is pressed by a hydraulic press. Although thi...

[0003] In the existing powder metallurgy process, when the mold tooling is used for pressing, the metal powder will be accumulated around the notch of the mold in advance, and then the metal powder will be automatically pushed into the groove of the mold by the push plate and the notch will be smoothed The metal powder is then pressed with a hydraulic press. Although this method ensures that the metal powder can be quantitatively loaded into the mold groove, the metal powder accumulated around it may be taken away by the flow of air, resulting in waste of raw materials and being easily inhaled by people.
