Problems solved by technology

[0002] Due to the difference in powder fluidity, powder metallurgy products often have disadvantages such as uneven blanking, difficult filling and unstable product quality during pressing, especially for laser welding diamond tools. The cross-linking of layers will seriously affect the welding performance and strength of the cutter head
At present, most powder metallurgy companies use manual pressing or automatic pressing after powder granulation to solve the above problems, but manual pressing and powder granulation are costly and inefficient

Embodiment Construction

[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The specific embodiments described here are only used to explain the present invention, not to limit the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not constitute a conflict with each other.

[0025] Such as figure 1 The shown powder metallurgy compression molding powder filling device includes a feeding box 5, a control system (not shown in the figure) and at least one feeding pipeline. The feeding pipelines in this embodiment are two, and the two feeding pipelines The feeding pipelines are arranged side by side. Each feeding pipeline comprises a primary hopper 1 and a secondary hopper 3 that is communicated w...

Abstract

The invention discloses a powder metallurgy compression molding powder filling device and a control method thereof. The device comprises a material feeding box and at least one path of material conveying pipeline. Each material conveying pipeline comprises a first-stage hopper and a second-stage hopper which is communicated with the first-stage hopper via a material discharging pipe. The second-stage hopper is communicated with the material inlet of the material feeding box via a conveying pipe. The second-stage hopper is internally provided with a height detection sensor. The material feeding box is connected with a pneumatic vibrator. The height detection sensor and the material feeding box are connected with a control system. The height detection sensor can detect height of powder in real time and feed back to the control system so that material tainting and reduction of precision caused by oversized speed of material discharging and excessive accumulate of powder can be avoided; the material feeding box has vibration in two mutually perpendicular directions of the material feeding plane so that filling performance of powder and uniformity of material discharging can be guaranteed; and a great solving scheme is provided to automatic compression of powder which is poor in fluidity and difficult to fill so that the device is widely suitable for the powder metallurgy compression molding technology.

Description

technical field [0001] The invention belongs to a powder metallurgy compression molding process, in particular to a powder metallurgy compression molding powder filling device and a control method. Background technique [0002] Due to the difference in powder fluidity, powder metallurgy products often have disadvantages such as uneven blanking, difficult filling and unstable product quality during pressing, especially for laser welding diamond tools. The cross-linking of layers will seriously affect the welding performance and strength of the cutter head. At present, most powder metallurgy companies use manual pressing or automatic pressing after powder granulation to solve the above problems, but manual pressing and powder granulation are costly and inefficient. Therefore, it is of great significance to speed up the research, development and promotion of powder filling equipment and processes that can be used without granulation and are easy to automate.
