Embodiment 1

[0032] Step 1: Turn on the resistance heater 24 and the temperature control system 3, and set the temperature of the heating steel plate 23 in the carbonization chamber to 500°C.

[0033] Step 2: Start the speed-regulating motor 12 of the metal chain conveyor 1, and control the running speed of the chain feed block 15 to 3 meters per minute.

[0034] Step 3: When the temperature of the heating steel plate 23 in the carbonization chamber 2 reaches the set temperature, place the brake pad 4 on the stock steel plate 21, start the speed regulating motor 12, the sprocket drum 14 rotates, and the sprocket drum 14 drives the chain When the wheel rotates, when the sprocket is driving, the chain feed block 15 between the two chains 16 is moved forward and brought into the carbonization chamber. It is placed on the stock steel plate 21 and is located between the two chain feed blocks 15 and the brake pad 4 follows The chain feed block 15 enters the carbonization chamber, and the brake pad 4 ...

Embodiment 2

[0037] A surface carbonization treatment method for disc brake pad linings, repeating the steps in the above embodiment 1, but the treatment conditions set are different as follows:

[0038] The heating steel plate 23 in the carbonization chamber is set to a temperature of 550°C, and the running speed of the chain feed block 15 is controlled at 3.5 m / min.

Embodiment 3

[0040] A surface carbonization treatment method for disc brake pad linings, repeating the steps in the above embodiment 1, but the treatment conditions set are different as follows:

[0041] The heating steel plate 23 in the carbonization chamber is set to a temperature of 600° C., and the running speed of the chain feed block 15 is controlled at 4 m / min.

Abstract

The invention relates to a surface carbonization treatment device for a brake pad liner. The surface carbonization treatment device comprises a metal chain conveyor, a carbonization chamber and a temperature control system, wherein the metal chain conveyor comprises a rack, a chain wheel roller, a chain and a speed-regulating motor; the carbonization chamber comprises a carbonization chamber support and a carbonization chamber cover, a heating steel plate and heaters are arranged in the carbonization chamber, the heating steel plate is located under a chain feeding block of the upper chain and provided with one or more transverse through holes, the heaters are arranged in the transverse through holes of the heating steel plate, a material preparing steel plate is arranged on the carbonization chamber support, and one side of the material preparing steel plate makes contact with the heating steel plate; the temperature control system comprises a temperature sensor, a PID controller and a thyristor. The surface carbonization treatment device is high in carbonization speed and production efficiency and low in energy consumption, reduces labor intensity, improves production environment and achieves full-automatic temperature control.

Description

Technical field [0001] The invention relates to the technical field of preparation of disc brake pads, in particular to a device and method for carbonization treatment of brake pad linings. Background technique [0002] In order to drive the car safely and improve the braking effect of the brake pads, when the new car starts to run or after the brake pads are replaced, the brake pads should be subjected to a longer period of time and more times of running-in treatment. After running-in, the protruding points of the brake pads are smoothed, so that the brake discs and the brake pads can fit better and achieve better braking performance. The brake pads have a longer running-in period. During the running-in period, the speed of the car is restricted, which affects the normal use of the car. In order to reduce the running-in time, the surface of the automobile disc brake pad lining is carbonized. The current method is: cover a flat steel plate on the coke oven, when the surface te...
