Description

Technical Field

[0001] The utility model relates to the field of feeding equipment, in particular to a feeding slide table for bonding materials of a powder metallurgy brake pad friction body component. Background Art

[0002] Trains play a very important role in people's travel, especially long-distance travel. Most people prefer to travel by train, so the brake system is particularly important to ensure the safety of the train. In recent years, my country's high-speed railway has made rapid progress.

[0003] There are many ways to brake a train, such as resistance braking, magnetic rail braking, eddy current braking, friction braking, etc., among which friction braking is indispensable. Friction braking converts kinetic energy into heat energy through friction, and then dissipates it into the atmosphere. Friction braking of trains usually adopts two methods: disc braking and wheel braking. Disc braking uses the mutual friction between the brake disc and the brake pad to consume the train's kinetic energy, while wheel braking uses the mutual friction between the wheel and the brake shoe to consume the train's kinetic energy. At present, most of my country's high-speed trains use disc braking, while ordinary passenger and freight trains, large-scale track maintenance machinery and other trains mostly use wheel braking. Therefore, the performance of brake shoes and brake pads has become an important aspect related to the safety of train operation.

[0004] Most powder metallurgy brake pads are composed of friction body components, steel backs and related butterfly springs or retaining springs. The friction body components are made of friction body and friction body skeleton by pressure sintering. The friction body is made by mixing a number of powder metallurgy materials in a proportion, and then using a mixer to press the materials together using a hydraulic press. If the friction body and the friction body skeleton are directly attached to the friction body components produced by pressure sintering, the bonding strength between the friction body and the friction body skeleton will not meet the requirements of the standard because the friction body material contains non-metallic materials. Therefore, it is usually used to lay a layer of bonding material on the friction body to strengthen the bonding strength between the friction body and the friction body skeleton.

[0005] Since the material ratios of the friction body and the adhesive material are different, a tooling specifically used for storing and laying the adhesive material and the friction body material is required to realize such functions.

[0006] In the prior art, the utility model patent with application number CN201920192559.7 discloses an automatic feeding device for a hydraulic press, including a support plate, a mold cavity is fixedly connected to the rear side of the bottom of the support plate, tooth grooves are provided on both sides of the top of the support plate, a moving frame is provided on the top of the support plate, a first motor is fixedly connected to both sides of the moving frame, a gear is fixedly connected to the rotating shaft of the first motor, a funnel is fixedly connected to the inner cavity of the moving frame, a vertical pipe is connected to the bottom of the funnel, and the bottom of the vertical pipe runs through the bottom of the moving frame. The feeding device can automatically transport materials and reduce the workload.

[0007] However, the above-mentioned feeding device can only convey one type of material to the mold cavity, which cannot meet the production requirements of the powder metallurgy brake pad friction body assembly and needs to be improved. Utility Model Content

[0010] As a further improvement, the cross-sectional shapes of the first blanking hole, the second blanking hole and the third blanking hole are all the same as the cross-sectional shape of the pressing mold cavity.

[0011] As a further improvement, the first blanking hole, the second blanking hole and the third blanking hole are arranged along a straight line, and the straight line where the first blanking hole, the second blanking hole and the third blanking hole are located is parallel to the moving direction of the slide body.

[0012] As a further improvement, a material hopper is fixedly installed on the top of the first cavity, and the bottom of the material hopper is connected to the first blanking hole.

[0013] As a further improvement, a dividing plate is installed in the upper end of the third blanking hole, and a dividing shaft extending downward is fixedly installed on the dividing plate; two insert plates are symmetrically arranged relative to the dividing shaft, and the inner end of the insert plate is provided with an avoidance notch matching the dividing shaft.

[0014] As a further improvement, a shield is fixedly mounted on the third cavity, and a material guide hole is provided on the top of the shield and is located directly above the third blanking hole.

[0015] As a further improvement, a baffle for closing the upper end of the third blanking hole is movably mounted on the third cavity, and the baffle is driven by a fourth power component and moves laterally.
