A kind of precision blanking mechanism blanking method

Abstract

The invention discloses a precise discharging mechanism and a discharging method. The precise discharging mechanism comprises a shell, and the shell is internally provided with a spiral material conveying assembly. The spiral conveying assembly is provided with a material conveying shaft. The lower end of the spiral material conveying assembly is provided with a material distributing assembly. Thematerial distributing assembly and the spiral material conveying assembly are concentric. The material distributing assembly comprises material distributing partitions. The material distributing partitions are connected with the material conveying shaft and divide a horizontal face perpendicular to the material conveying shaft into a plurality parts. A discharging channel is formed between everytwo adjacent material distributing partitions. Materials conveyed from the spiral material conveying assembly are divided into the multiple parts by the material distributing assembly and are output along the discharging channels. The lower end of the material distributing assembly is connected with an adjusting assembly. The adjusting assembly is provided with an adjusting insertion plate, and the adjusting insertion plate blocks the multiple discharging channels so that the materials can be output from the discharging channel which is not blocked. According to the precise discharging mechanism and the discharging method, precise discharging of the materials in the brake block production process is achieved, a pattern that traditional discharging is carried out at the same speed all the time is changed, the discharging speed can be adjusted according to needs, the discharging speed can be controlled, and the discharging precision is guaranteed.

Description

technical field [0001] The invention relates to a blanking method of a precision blanking mechanism, in particular to a blanking method of a precision blanking mechanism for the production of brake pads. Background technique [0002] Brake pads refer to the friction material fixed on the brake drum or disc that rotates with the wheel, relying on the friction lining and friction pad to withstand external pressure and generate friction to achieve the purpose of vehicle deceleration. Various powder raw materials such as friction powder, graphite, reduced iron powder, tire powder, and copper powder are used in the production process of brake pads. [0003] At present, in the production process of brake pads, the accuracy of the feeding amount of brake pad materials is high, but in the prior art, the traditional screw feeder is used for feeding, and the materials passing through the screw feeder are directly discharged. Material, because the screw conveyor always runs at a certa...

Problems solved by technology

[0003] At present, in the production process of brake pads, the accuracy of the feeding amount of brake pad materials is high, but in the prior art, the traditional screw feeder is used for feeding, and the materials passing through the screw feeder are directly discharged. Material, because the screw conveyor always runs at a certain speed, the speed of the material cannot be changed, so that the speed control of the material cannot be realized, the accuracy of the material cannot be guaranteed, and the ratio of the material is affected, which in turn affects the brake pads. production quality
