Embodiment 1

[0034] refer to figure 1 and figure 2 , a pressing and forming device for metal powder, including a pressure head 10, an operating platform 20, a turntable 30, a material receiving mold frame 40, a molding die 50, a discharge track 60, and a green body pressing device 70, wherein the turntable 30 is set at the operating The platform 20 is driven to rotate by a variable frequency motor 31 . The turntable 30 is evenly provided with 20 through slots 32 penetrating to the operation platform 20 along the circumference of its upper end surface, and a material receiving mold frame 40 is fixed on the upper end surface of each through groove 32, and the shape of the material receiving mold frame 40 is It is determined according to the shape of the cutter head, which can be square, round, oval, etc. The through groove 32 communicates with the material receiving mold frame 40 , and the shape of the through groove is the same as that of the inner cavity of the material receiving mold f...

Embodiment 2

[0039] This embodiment is basically the same as Embodiment 1, the main differences are: feeding device, material receiving mold frame and turntable. refer to Figure 4 and Figure 5 , the feeding device of the present embodiment is a slope type track 72, one end of the slope type track 72 is connected to the conveyor belt 71, and the other end is connected to the material receiving mold frame 40, the slope type track 72 is fixed and does not contact the material receiving mold frame 40 . The upper end surfaces of the material receiving mold frames 40 are all arranged flush, and the height between the previous material receiving mold frame 40 and its corresponding position turntable 30 is equal to the height between the latter material receiving mold frame 40 and the corresponding position turntable 30 minus one raw material. The thickness of the billet ensures that the height of each feeding is equal. The molding process of this embodiment is also basically the same as that...

Embodiment 3

[0041] This embodiment is also basically the same as Embodiment 1, and the main difference lies in: the feeding device and the conveying device. refer to Figure 6 , the conveyor belt of the present embodiment comprises two rotary conveyor belts 71 moving in opposite directions, a gap is provided between the two rotary conveyor belts 71, the gap is just above the material receiving mold frame 40, and the two rotary conveyor belts 71 There are several convex blocks 711 evenly spaced. The distance between adjacent convex blocks 711 on the same rotary conveyor belt 71 is equal and greater than the length of the green body. The feeding device is an elastic support body located on the operating platform directly below the gap. 72. The molding process of this embodiment is also basically the same as that of Embodiment 1, the main difference being the way of feeding and feeding: the green body in this embodiment is conveyed by one of the rotary conveyor belts 71, and slides to two s...

Abstract

The invention provides a metal powder compression molding device. The metal powder compression molding device comprises a pressure head, an operating platform, a rotary disk, material receiving molding frames, a forming mold, a discharge track and a plurality of billet pressing devices. The rotary disk is arranged on the operating platform. A plurality of through grooves are evenly formed in the periphery of the rotary disk. Each material receiving molding frame is fixed to the upper end face of the corresponding through groove. Each billet pressing device is provided with a conveying device and a charging device. The conveying devices are sequentially arranged at equal intervals. The charging devices are in butt joint with the conveying devices and the material receiving molding frames respectively. The forming mold and the discharge track are arranged in the same circumference of the operating platform under the rotary disk. The pressure head is arranged over the forming mold. According to the metal powder compression molding device, the billet pressing devices are utilized to press powder for manufacturing diamond cutters into billets, compression molding is carried out on the collected billets, and then feeding, pressing, discharging and other processes are carried out synchronously. Through the adoption of a multi-layer cutting head, the production efficiency is high, dust is reduced, losses of the powder are reduced, resources are saved and the working environment is improved.

Description

technical field [0001] The invention relates to the manufacture of a diamond tool, in particular to a metal powder press molding device and process. Background technique [0002] At present, the manufacturing process of multi-layer diamond tools usually includes the following steps: First, manually weigh several kinds of powders required for making diamond tools; Finally, the powder needs to be shaken flat before loading another powder; after all the powder is loaded, it is finally equipped with an indenter and pressed into shape. [0003] However, through long-term practical production, it has been found that this production process mainly has the following shortcomings: 1. The dust in the working place is flying, and the environment is extremely harsh, which seriously affects the health of the staff; 2. Due to the large volume of powdery items, Installed in a graphite mold, it takes up a lot of graphite mold space; 3. The powder is easy to lose during the molding and ...
