Description

Technical Field

[0001] The invention relates to the technical field of friction plate processing, and in particular to a control method for improving the firmness of a core plate and a lining plate. Background Art

[0002] Friction plates refer to components consisting of core plates and friction linings or friction material layers, which are widely used in mechanical engineering, mechanical parts and clutches. Friction plates, also known as brake pads, are vital safety components in the automotive braking system.

[0003] Friction plates can be divided into many types according to their shapes, mainly including disc plates (flat), drum plates (arc-shaped), brake bands (commonly used in agricultural machinery and engineering machinery, which are soft friction materials), brake shoes (such as train brake shoes and oil rig brake shoes, which are arc-shaped but thicker), clutch plates (generally ring-shaped products) and anisotropic friction plates (mostly used in various engineering machinery, such as friction presses, electric hoists, etc.).

[0004] The friction pad is a key component installed in the brake system. It slows down and stops the vehicle by friction with the brake disc or brake drum. When the brake pedal is pressed, the brake will clamp the brake friction pad, causing friction with the brake disc or brake drum, and use friction to convert the vehicle's kinetic energy into heat energy, thereby achieving vehicle braking. The quality and performance of the friction pad are directly related to the braking effect, which in turn affects driving safety. Summary of the invention

[0005] The present invention mainly solves the deficiencies in the prior art and provides a control method for improving the firmness of the core plate and the lining, which has the advantages of compact structure, convenient operation and good running stability. It solves the problem of firm connection between the core plate and the lining. It avoids the situation where the core plate and the lining fall off and causes brake failure, and improves the reliability and safety of the brake system.

[0006] The above technical problems of the present invention are mainly solved by the following technical solutions: A control method for improving the firmness of a core plate and a lining, the friction plate comprises a core plate, both end surfaces of the core plate are provided with linings firmly connected to the core plate, a plurality of flange rings integrated with the core plate are provided between the lining and the core plate, and a plurality of oil grooves are provided at the upper end of the lining.

[0008] Step 2: Lathe flange ring.

[0009] Step 3: Sandblast the polished surface.

[0011] Step 5: Apply adhesive to both ends of the core board, and then attach the lining to the core board.

[0012] Step 6: The attached lining and core board are completed under pressure and heat preservation conditions.

[0013] Preferably, the lining is copper-based or paper-based; when the lining is copper-based, the oil groove is pressed during the spraying or sintering process of the lining and the core plate; when the lining is paper-based, the oil groove is formed by a grooving machine after the lining is paper-formed and polished.

[0014] Preferably, when the lining is copper-based, the lining is bonded to the core plate and then sent to a pressure furnace. At a pressure of 1.5 to 1.8 tons, the temperature in the furnace reaches 770 to 830 degrees, and the sintering process is completed by heating for 2.5 hours and keeping warm for 6 hours.

[0015] Preferably, when the lining is paper-based, the lining surface is coated with glue, and the lining and the core plate are hot-pressed at a temperature of 180°C, a pressure of 15-20 MPa, and a high-temperature hot-pressing composite time of 5-10 minutes using a vulcanizer.

[0016] Preferably, the oil groove is a spiral groove, a parallel groove, a radial groove, a waffle groove or an arc groove.

[0017] Preferably, a hub disc integrated with the core plate is provided in the core plate, and the hub disc is connected to the drive shaft by a spline-type retaining ring with limited insertion.

[0018] Preferably, when the flange ring is processed, the cross section of the flange ring is a trapezoidal structure, thereby increasing the fitting area between the lining and the core plate.

[0019] As a preferred method, the core board bonding surface is sandblasted to ensure verticality while increasing the concave-convex texture of the bonding surface, thereby eliminating fatigue stress and extending the service life.

[0020] The present invention can achieve the following effects: The present invention provides a control method for improving the firmness of a core plate and a lining.
