背景技术Background technique
摩擦片是各种机械设备中最重要的零件之一，它们利用摩擦力进行工作，摩擦片要可靠地工作，必须具有足够高且稳定的摩擦系数，耐磨性、耐热性、机械强度高，不会与对偶件咬死。摩擦片按材料可分为金属，纤维增强树脂基，如石棉、半金属、无石棉、纸基、碳基，或粉末冶金摩擦材料等。粉末冶金摩擦材料由于在各种工作条件都具有高的耐热性、摩擦系数及耐磨性而得到广泛运用。湿式铜基粉末冶金摩擦片的应用范围一直在扩大，它的优点是结合平稳、耐磨性高、使用寿命长，它一般采用压烧工艺，工艺流程为摩擦层的配料→混料→压型→与镀铜钢芯板拼装→加压烧结→油槽加工；形成一种中间为一镀铜钢芯板11，上下两面均加压烧结有摩擦层12的摩擦片，它是在钢芯板1的表面上至少有一层镀铜层13，见附图1所示。所述的加压烧结见附图2所示，它是在一加压罩14内进行，摩擦片15置于上下的传压垫板16之间，加压罩14的上面布置有可紧压于其上的油压缸17。上述压烧工艺虽然使得摩擦层与钢芯板结合强度较高，但仍存在许多缺点，如钢芯板经烧结退火后硬度和强度降低，加压烧结时必须用传压垫板增加能耗，产品易出现压偏，摩擦层里的低融点成份易被挤压出来，俗称出合金瘤，从而降低了摩擦片摩擦性能，影响了产品的外观质量，周期较长，成本较高。The friction plate is one of the most important parts in various mechanical equipment. They use friction to work. To work reliably, the friction plate must have a sufficiently high and stable friction coefficient, high wear resistance, heat resistance, and high mechanical strength. , will not bite to death with the dual piece. The friction plate can be divided into metal, fiber reinforced resin base, such as asbestos, semi-metal, non-asbestos, paper base, carbon base, or powder metallurgy friction material according to the material. Powder metallurgy friction materials are widely used due to their high heat resistance, friction coefficient and wear resistance under various working conditions. The application range of the wet copper-based powder metallurgy friction plate has been expanding. Its advantages are stable combination, high wear resistance and long service life. It generally adopts the pressing and firing process. The process flow is the ingredients of the friction layer→mixing→pressing → Assemble with copper-plated steel core plate → pressurized sintering → oil groove processing; form a friction plate with a copper-plated
发明内容Contents of the invention
本发明的目的在于克服上述存在的不足，而提供一种采用摩擦片的钢芯板不用镀铜，摩擦层无压烧结和一般粉末冶金压坯一样可在网带炉进行，生产周期较短，生产成本低的湿式铜基粉末冶金摩擦片及制造方法。The purpose of the present invention is to overcome the above-mentioned deficiencies, and provide a steel core plate using a friction plate without copper plating. The pressureless sintering of the friction layer can be carried out in a mesh belt furnace like a general powder metallurgy compact, and the production cycle is shorter. A wet-type copper-based powder metallurgy friction plate with low production cost and a manufacturing method thereof.
本发明的目的是通过如下技术方案来完成的，一种湿式铜基粉末冶金摩擦片，它主要由中间的钢芯板和至少一侧上摩擦层组成，所述的钢芯板的至少一面上结合有一层胶膜层，并在胶膜层上再复合有一层摩擦层。The object of the present invention is achieved through the following technical scheme, a wet copper-based powder metallurgy friction plate, which is mainly composed of a steel core plate in the middle and a friction layer on at least one side, and at least one side of the steel core plate is An adhesive film layer is combined, and a friction layer is compounded on the adhesive film layer.
所述的钢芯板的上下两面上各结合有一层胶膜层，并在胶膜层上再各自复合有一层摩擦层；在摩擦层内的孔隙内含有已固化的改性酚醛树脂胶。The upper and lower surfaces of the steel core board are respectively combined with a layer of film layer, and a layer of friction layer is respectively compounded on the film layer; the pores in the friction layer contain cured modified phenolic resin glue.
一种湿式铜基粉末冶金摩擦片的制造方法，该方法至少包括摩擦层配料、混料、压型、烧结、与钢芯板拼装、油槽加工，其特征在于所述的烧结采用在连续烧结炉内无压烧结，烧结后的摩擦层在真空浸胶槽内常温浸胶后并烘干而成，然后与钢芯板进行拼接，在拼接前，先对钢芯板表面涂胶；拼接后在平板硫化机上加压固化后制成。A method for manufacturing a wet-type copper-based powder metallurgy friction plate, the method at least includes friction layer batching, mixing, pressing, sintering, assembling with a steel core plate, and oil tank processing, characterized in that the sintering is carried out in a continuous sintering furnace Internal pressureless sintering, the friction layer after sintering is dipped and dried in a vacuum dipping tank at room temperature, and then spliced with the steel core plate. Before splicing, the surface of the steel core plate is coated with glue; It is made after pressing and curing on a flat vulcanizing machine.
所述的摩擦层在真空浸胶槽内常温浸胶50--70分钟，胶液为YSM-1用丙酮稀释到浓度50％，在80-95℃温度下烘干，再在150-160℃固化50-70分钟。The friction layer is dipped in a vacuum dipping tank at room temperature for 50--70 minutes, the glue is YSM-1 diluted with acetone to a concentration of 50%, dried at 80-95°C, and then dried at 150-160°C Cure for 50-70 minutes.
所述的摩擦层与涂胶厚度在0.05-0.1mm的钢芯板拼装叠合后在平板硫化机上经160-180℃、0.5-1.2Mpa压力下固化8-12分钟。The friction layer and the steel core plate with glue coating thickness of 0.05-0.1 mm are assembled and laminated, and then cured on a flat vulcanizer for 8-12 minutes at 160-180° C. and 0.5-1.2 Mpa pressure.
本发明由于芯板不用镀铜和不用随摩擦层烧结，生产成本可降低30％以上；与现有的压烧工艺相比，胶粘工艺摩擦片摩擦层孔隙度较高，因而摩擦系数也相对较高。最突出的一点是：因钢芯板没有随摩擦层高温烧结，可因特殊用户要求，加工芯板有硬度的摩擦材料(传统工艺无法做到这一点)，尺寸精度可保持原有机加工水平。Since the core plate of the present invention does not need copper plating and sintering with the friction layer, the production cost can be reduced by more than 30%. higher. The most prominent point is: because the steel core plate is not sintered at high temperature with the friction layer, the friction material with hardness on the core plate can be processed due to special user requirements (traditional technology cannot do this), and the dimensional accuracy can maintain the original machine processing level.
本发明与现有技术相比，具有如下几个特点：一是传统粉末冶金摩擦片是采用加压烧结实现摩擦层与钢芯板的冶金结合，这种方法烧结后摩擦层孔隙率低，约为8-12％，在油中动摩擦系数0.05-0.06；而本发明采用的是连续式无压烧结，这种工艺效率高，摩擦层的孔隙率高，约为20-30％，有利于提高在油中的动摩擦系数；本发明所述工艺生产的摩擦片在油中动摩擦系数为0.055-0.07。Compared with the prior art, the present invention has the following characteristics: First, the traditional powder metallurgy friction plate adopts pressure sintering to realize the metallurgical combination of the friction layer and the steel core plate, and the porosity of the friction layer after sintering by this method is low, about It is 8-12%, and the coefficient of dynamic friction in oil is 0.05-0.06; and what the present invention adopts is continuous pressureless sintering, and this process efficiency is high, and the porosity of friction layer is high, is about 20-30%, helps to improve Coefficient of dynamic friction in oil; the coefficient of dynamic friction in oil of the friction plate produced by the process of the present invention is 0.055-0.07.
二是钢芯板不用镀铜，降低成本；传统工艺为保证摩擦层与钢芯板结合强度，芯板必须镀铜。The second is that the steel core board does not need to be copper-plated to reduce costs; in order to ensure the bonding strength of the friction layer and the steel core board in traditional technology, the core board must be copper-plated.
三是传统工艺的烧结是在一个专门的钟罩炉内进行，周期长，一炉产品约为10-15小时。效率低；本发明采用网带炉连续烧结平板硫化机加压加热固化8-10分钟，效率可提高20倍以上。The third is that the sintering of the traditional process is carried out in a special bell furnace, and the cycle is long, and the product of one furnace is about 10-15 hours. The efficiency is low; the present invention adopts the continuous sintering of the mesh belt furnace and the flat vulcanizing machine to pressurize, heat and cure for 8-10 minutes, and the efficiency can be increased by more than 20 times.
四是传统工艺芯板要经过750-820℃烧结，硬度强度显著降低，尺寸精度降低；本发明由于芯板不经过750-820℃烧结，可克服传统工艺上述缺点。Fourth, the core board of the traditional technology needs to be sintered at 750-820°C, so the hardness and strength are significantly reduced, and the dimensional accuracy is reduced; because the core board of the present invention does not undergo sintering at 750-820°C, the above-mentioned shortcomings of the traditional technology can be overcome.
