Background
At present, the friction base material on the brake pad is generally weighed and then pressed to form in the field of brake pad processing by manual weighing, the friction base material of the automobile brake pad is formed by pressing fiber, ceramic, metal powder and other powdery raw materials, and manual weighing is carried out according to the using amount of each friction base material.
The automatic material weighing machine for weighing materials is also available on the market, but because the friction base material of the brake pad is simultaneously produced according to different materials customized, the automatic material weighing machine on the market can only simultaneously weigh one material, different materials need multiple devices for weighing, the cost for purchasing the material weighing device is high, and because the material weighing device on the market needs to lift the material powder into a blanking hopper and then weigh the material through blanking, the powder is often required to be lifted by workers, the labor intensity is high, the possibility of tipping is caused when the powder is lifted, and the workshop pollution is caused, so that operators are inevitably injured by crashing.
Moreover, the powder of the friction material of the brake pad is easy to cause performance reduction after being extruded, and the powder is easy to be extruded by a material weighing mechanism of a material weighing machine on the market, so the material weighing machine is not suitable for automatic material weighing of the friction material of the brake pad.
Therefore, the applicant proposes an automatic material weighing machine for the brake pad friction material from 2018, 3 and 06, and the authorized bulletin numbers of the automatic material weighing machine are as follows: CN208217937U, the date of authorized announcement is 12 months and 11 days in 2018, and the following technical scheme is adopted: the small-sized brake pad production device comprises a rack, wherein a storage bin, a weighing mechanism and a conveying device are sequentially arranged at the front end of the rack from top to bottom, a feeding channel is arranged at the rear end of the rack, conveying powder in the storage bin is communicated with the storage bin through the feeding device, the powder in the storage bin is conveyed to the weighing mechanism through the feeding channel and the feeding device, when the small-sized brake pad is produced, a material cup on the conveying mechanism can be directly replaced by a plurality of brake pad molds distributed at equal intervals due to less powder required by the small-sized brake pad, the molds are conveyed into a pressing machine for pressing after the powder is directly conveyed into the molds, but the brake pad molds are sequentially opened according to actual conditions due to more brake pad types in the actual production process, and after the brake pad molds are replaced, the positions of a feeder and a metering hopper of the weighing mechanism are designed again according to the positions of the molds, so that the production cost is undoub, and a set of material weighing mechanism needs to be designed or a matched material weighing machine needs to be purchased again for the brake pad of each model, so that the universality is poor.
