Embodiment 1

[0025] Example 1: Operate according to the above steps, use the adhesive material with a volume ratio of adhesive and curing agent of 1:1, mix the adhesive and curing agent evenly, and bond the new friction sheet 1 with the old friction sheet 2 The gap 4 between them is 3mm, the setting pressure of the accumulator of the bonding machine is 8MPa, and the pressure duration is 6 hours. The service life of the brand-new tamping hammer friction plate is about 1 to 1.5 years, and the service life of the friction plate bonded in this embodiment is about 0.5 years.

Embodiment 2

[0026] Example 2: Operate according to the above steps, use the adhesive material with a volume ratio of adhesive and curing agent of 1:1, mix the adhesive and curing agent evenly, and bond the new friction sheet 1 with the old friction sheet 2 The gap 4 between them is 3mm, the setting pressure of the accumulator of the bonding machine is 10.5MPa, and the pressure duration is 4 hours. The service life of the friction plate after bonding in this embodiment is about 0.8 years.

Embodiment 3

[0027] Example 3: Operate according to the above steps, use the adhesive material with a volume ratio of adhesive and curing agent of 1:1, mix the adhesive and curing agent evenly, and bond the new friction sheet 1 with the old friction sheet 2 The gap 4 between them is 3mm, the setting pressure of the accumulator of the bonding machine is 10.7MPa, and the pressure duration is 4 hours. The service life of the friction plate after bonding in this embodiment is about 0.8 years.

Abstract

The invention relates to the field of equipment maintaining, in particular to a tamping coke oven tamping hammer fiction piece local bonding method. The method comprises the steps that a. a pneumatic shovel blade is used for carrying out clearing on a broken position of a tamping hammer old friction piece, and a bonding face is formed; b. the length of the bonding face is measured, the size of a new friction piece is determined hereby, and the fact that a gap exits between the new friction piece and the old friction piece after bonding is guaranteed; c. the new friction piece is cut and ground to meet the size requirement in the step b; d. a tamping hammer processed by the step a is placed on a bonding machine, a bonding face is upward, and bonding materials are evenly arranged on the bonding face in a coating mode; e. the polished new friction piece is placed on the bonding face in a paving mode and is pressed until the new friction piece is flat, and accurate alignment is guaranteed; and f. the bonding machine is started, the new friction piece and the tamping hammer are pressurized to specific pressure, the specific pressure is maintained for a certain period, the bonding machine is shut down, pressure is removed, and the tamping hammer is taken off. The method is good in bonding effect and high in bonding intensity, and the service life of the friction piece can be prolonged.

Description

technical field [0001] The invention relates to the field of equipment maintenance, in particular to a local bonding method for a tamping hammer friction plate of a tamping coke oven. Background technique [0002] Tamping coke oven tamping hammer is an important tool that uses mechanical transmission to throw the tamping hammer upwards, and then falls freely by the hammer's own weight to impact and tamp coal into briquettes. The tamping hammer weighs 379kg, has a total length of 8300mm, a width of 220mm, and a height of 110mm. Among them, each tamping hammer has two friction plates, which are respectively bonded on both sides of the body of the tamping hammer. The total length of the friction plates on each side is 6850 mm, the width is 170 mm, and the thickness is 10 mm. [0003] In the past, after the friction plate of the tamping hammer was damaged, it was heated to 240°C by the bonding machine, and the two old friction plates were removed, polished and cleaned, and then...
