Multi-feeding compound powder forming mechanism for powder forming machine

Abstract

The invention relates to a multi-feeding compound powder forming mechanism for a powder forming machine. The multi-feeding compound powder forming mechanism is improved on the basis of a traditional multi-feeding compound powder forming machine which comprises a first feeding mechanism, a cavity block, a core rod and a first punching head. The multi-feeding compound powder forming machine further comprises a second feeding mechanism which comprises a second powder boot, a second powder barrel and a second driving mechanism for driving the second powder boot to reciprocate on a power conveying plate, wherein a punching head set which is matched with the second feeding mechanism is sleeved on the core rod; the punching head set is composed of a second punching head and an auxiliary punching head, both of which can move up and down; and the auxiliary punching head is located between the first punching head and the second punching head along the radial direction. With such a structure, the multi-feeding compound powder forming mechanism can be used for primarily forming a finished product of powder containing various components in one mould cavity and acquiring a product with a hardness difference after being sintered, thereby solving the problem that alloy powder is difficult to be processed in subsequent production, saving plenty of production cost for an enterprises, and being worthy of application in powder forming industry.

Description

technical field [0001] The invention relates to a powder forming machine, in particular to a multi-feed composite powder forming mechanism for forming a part with multiple different powders in the powder forming machine. Background technique [0002] The powder forming machine is a kind of equipment that presses powders such as cemented carbide and precision ceramics into products at one time. Due to the high production efficiency and high precision of the pressed products, the powder forming machine has gradually replaced some traditional processing equipment. However, the products formed by the existing powder forming machine are all pressed by the same powder. Correspondingly, there is only one set of feeding mechanism on the powder forming machine. There is the material shoe of feeding hole, just discloses such a kind of feeding mechanism as CN201079955Y " full-automatic feeding numerical control manipulator " as Chinese patent authorization announcement number. When w...

Problems solved by technology

That is to say, when a part of a product needs to have higher strength, the existing powder forming machine can only process products with the same hardness in each part, which not only brings troubles to subsequent processing, but also the powder required for high hardness products The requirements are higher, and the powder price is very expensive, which brings a great economic burden to manufacturers and users.
