Description

Technical Field

[0001] The present application relates to the technical field of clutch friction plates, and in particular to a production process for clutch friction plates of engineering vehicles. Background Art

[0002] Construction vehicles are the backbone of a construction project. Common construction vehicles include heavy-duty transport vehicles, large cranes, excavators, bulldozers, and road rollers. The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The clutch output shaft is the input shaft of the gearbox. The clutch is a common component in mechanical transmissions that can separate or engage the transmission system at any time. It is one of the most important components of construction vehicles, and the friction plate is one of the components of the clutch. The clutch friction plate is a composite material with friction as its primary function and structural performance requirements. The product performance of existing clutch friction plates can basically meet normal use, and the wear resistance can meet the requirements, but the overall strength is low and the service life is short. The clutch friction plate is mainly composed of a base plate and raw materials. During the production process, a composite glue is applied to the base plate, and the raw materials are coated on the base plate. The raw materials are fixed to the base plate by bonding and extrusion. During this process, the composite glue will overflow to the outer peripheral side of the base plate due to extrusion and solidify, thus affecting the quality of the finished product.

In this embodiment, the proportions of phenolic resin powder, natural rubber, alumina, zircon, graphite, molybdenum disulfide, talc, mica, ceramic fiber and carbon fiber are 25%, 25%, 1.5%, 1.5%, 1.5%, 1.5%, 1.5%, 1.5%, 20% and 21.5% respectively. Phenolic resin powder and natural rubber together constitute a binder, alumina, zircon, graphite, molybdenum disulfide, talc and mica together constitute a filler, which adjusts or matches the friction performance of the clutch friction plate, so that the wear resistance of the clutch friction plate meets the requirements, and the ceramic fiber and carbon fiber together constitute a reinforcing part, which can improve the overall strength of the clutch friction plate, thereby improving the service life;

[0067] S3: Patch fixing, applying composite glue on the surface of the substrate, and coating the raw materials on the substrate;

[0068] S4: Curing and shaping, the substrate and the raw material are extruded by an extrusion device, and cooled to obtain a finished product. When the substrate and the raw material are extruded by the extrusion device, the composite glue will overflow to the outer peripheral side of the substrate due to the extrusion and solidify;

[0069] In the production process of the above-mentioned engineering vehicle clutch friction plate, a trimming device is required to remove the cured composite glue on the outer peripheral side of the substrate. The trimming device includes:

[0070] Base plate 1;

[0071] A clamping and fixing mechanism 2 is provided on the base plate 1 and is used to clamp and fix the substrate;

[0072] The portal frame 3 is arranged on the bottom plate 1. The portal frame 3 consists of two vertical beams and one horizontal beam. The two vertical beams are arranged vertically on the bottom plate 1, and the horizontal beam is arranged horizontally on the two vertical beams.

[0073] The rotating rod 4 is rotatably mounted on the portal frame 3 in a horizontal direction via a bearing. The rotating rod 4 is rotatably mounted on the crossbeam of the portal frame 3 in a horizontal direction via a bearing and is located between opposite sides of the two vertical beams.

[0074] The first motor 5 is arranged on the portal frame 3 and the output shaft is connected to the rotating rod 4. The first motor 5 is arranged on the crossbeam of the portal frame 3;

[0075] Two electric push rods 6 are symmetrically arranged in the vertical direction, the fixed ends of the two are connected to the rotating rod 4, and the movable ends of the two are provided with a trimming mechanism 7;

[0076] In the initial state, the movable ends of the two electric push rods 6 are in the retracted state, and the trimming mechanism 7 is close to the rotating rod 4. When the composite glue solidified on the outer peripheral side of the substrate is removed, the substrate is placed horizontally on the bottom plate 1, and the substrate is clamped and fixed by the clamping and fixing mechanism 2. The two electric push rods 6 are opened, and the movable ends of the two electric push rods 6 are extended at the same time, driving the trimming mechanism 7 to move downward in the vertical direction until the trimming mechanism 7 is close to the outer peripheral side of the substrate. The first motor 5 is turned on and the first motor 5 works. The output shaft rotates, driving the rotating rod 4, the two electric push rods 6 and the trimming mechanism 7 to rotate synchronously. Mechanism 7 removes the composite glue solidified on the outer peripheral side of the substrate, thereby ensuring the quality of the finished product. Finally, the first motor 5 is turned off, and the movable ends of the two electric push rods 6 are driven to retract at the same time, driving the trimming mechanism 7 to move upward in the vertical direction until the trimming mechanism 7 is away from the outer peripheral side of the substrate, and then the clamping and fixing mechanism 2 is used to release the clamping and fixing of the substrate, and the substrate can be removed from the base plate 1. In summary, the clutch friction plate made by this process has high overall strength, long service life, and wear resistance that meets the requirements. The composite glue solidified on the outer peripheral side of the substrate is removed by the trimming device to ensure the quality of the finished product, so it is more practical.

[0077] like Figure 1 As shown, in some embodiments, in step S2, the fineness of the phenolic resin powder is above 200 mesh, which is beneficial to the uniformity of the dispersion of the mixture and can reduce the amount of phenolic resin powder used.

[0078] like Figure 1 As shown, in some embodiments, in step S4, the cooled finished product is immersed in a passivation solution for water washing, and the washed finished product is taken out of the passivation solution and dried. The passivation solution has surface rust removal, rust prevention and passivation functions, avoiding secondary corrosion caused by strong acid pickling and rust removal, which in turn causes the substrate surface to be porous. At the same time, it also avoids the problem of rust expansion caused by the pickling solution penetrating into the interior of the surface. The passivation solution can be coupled with the phenolic resin powder and has good bonding force, thereby further improving the service life of the clutch friction plate.

[0079] like Figure 1 As shown, in some embodiments, the passivation solution is composed of synthetic aluminum and an adhesion promoter, does not contain harmful substances and also has flame retardant properties.

The fixed blocks 204 are located in the arcuate slots 207 and slidably engage with them. As mentioned above, the number of the arcuate slots 207 is also six.

[0085] The second motor 208 is provided on the fixed housing 201 and the output shaft is connected to the shaft 205. In the initial state, the six arc-shaped plates 203 are all close to the fixed housing 201. Referring to the above, the substrate is placed horizontally on the bottom plate 1 so that the six arc-shaped plates 203 are all located on the inner side of the substrate. The second motor 208 is turned on and the second motor 208 works. The output shaft rotates forward, driving the shaft 205 and the dial 206 to rotate synchronously. The six fixed blocks 204 slide in the six arc grooves 207 respectively, thereby driving the six sliding rods 202 to slide synchronously. The six arc-shaped plates 203 are respectively in the six sliding grooves 207. The six curved plates 203 move synchronously under the drive of the rod 202 until all six curved plates 203 touch the inner side of the substrate to achieve clamping and fixing of the substrate. Conversely, when the substrate needs to be unclamped and fixed, the second motor 208 is turned on, the second motor 208 works, the output shaft is reversed, and the shaft 205 and the dial 206 are driven to rotate synchronously. The six fixed blocks 204 slide in the six curved grooves 207 respectively, thereby driving the six sliding rods 202 to slide synchronously. The six curved plates 203 move synchronously under the drive of the six sliding rods 202 until the six curved plates 203 are away from the inner side of the substrate.

The two cutter heads 706 move synchronously with the two slide bars 705 until the two cutter heads 706 are close to the outer peripheral side of the substrate. Then the first motor 5 is turned on, and its output shaft rotates, driving the rotating rod 4 and the two electric push rods 706 to rotate. The push rod 6, the cross bar 701, the forward and reverse screw rods 702, the third motor 703, the bevel gear assembly 704, the two slide rods 705 and the two cutter heads 706 rotate synchronously, and the composite glue solidified on the outer peripheral side of the substrate is removed by the two rotating cutter heads 706.
