Description

制动钢背表面高粗糙度的处理方法Methods for treating high surface roughness of brake steel backing 技术领域Technical Field

 本发明涉及制动钢背表面处理技术领域，具体涉及一种制动钢背表面高粗糙度的处理方法。This invention relates to the field of brake steel back surface treatment technology, and specifically to a method for treating high roughness on the back surface of brake steel.

背景技术Background Technology

 随着制动安全性的要求不断提升，刹车片的剪切力已经成为衡量刹车片性能的关键性因素之一。要取得更高的剪切力，就需要摩擦材料与制动钢背的粘结力更高，这就需要制动钢背与摩擦材料粘接面上要有更高的粗糙度，通过试验数据的分析，这个粗糙度的要求为Ra≥2.0，或Rz≥30。With increasingly stringent requirements for braking safety, the shear force of brake pads has become one of the key factors in evaluating brake pad performance. To achieve higher shear force, the adhesion between the friction material and the brake backing needs to be stronger, which in turn requires a higher surface roughness on the bonding surface between the brake backing and the friction material. Analysis of experimental data indicates that this roughness requirement is Ra≥2.0 or Rz≥30.

 传统制动钢背提升粗糙度的方式主要采用抛丸和喷砂工艺，这种工艺可以满足制动钢背表面粗糙度的要求，但是工艺的弊端也非常多：Traditional methods for improving the surface roughness of brake steel backing mainly employ shot blasting and sandblasting processes. While these processes can meet the surface roughness requirements of brake steel backing, they also have many drawbacks:

1、抛丸和喷砂工艺是会导致产品外形尺寸和平面度也发生改变且变化过程随意性大、不可控，导致产品的质量稳定性差；1. Shot blasting and sandblasting processes can alter the product's dimensions and flatness, and the changes are highly arbitrary and uncontrollable, resulting in poor product quality stability.

2、需要通过提升冲压的管控力度，缩小冲压公差带来保障最后成品的合格，这样在冲压过程的质量成本就要比过去高出1.5～2倍；2. It is necessary to improve the control of stamping and reduce stamping tolerances to ensure the quality of the final product. This will increase the quality cost of the stamping process by 1.5 to 2 times compared to the past.

3、无论是抛丸还是喷砂工艺其作业环境是十分恶劣的，会产生很大粉尘和噪音。3. Both shot blasting and sandblasting processes operate in extremely harsh environments, generating significant dust and noise.

发明内容Summary of the Invention

 本发明主要解决现有技术中存在的不足，提供了一种制动钢背表面高粗糙度的处理方法，其具有操作便捷、运行稳定性好和效率高的优点。解决了制动钢背提高表面粗糙度引起粉尘和噪音大的问题。通过制动钢背与摩擦材料粘接面进行处理避免粗糙度工艺，获得更稳定的质量和高粗糙度配合面的效果。This invention addresses the shortcomings of existing technologies by providing a method for treating the high surface roughness of brake steel backing surfaces. This method offers advantages such as convenient operation, good operational stability, and high efficiency.

 本发明能够达到如下效果：The present invention can achieve the following effects:

本发明提供了一种制动钢背表面高粗糙度的处理方法，与现有技术相比较，具有操作便捷、运行稳定性好和效率高的优点。解决了制动钢背提高表面粗糙度引起粉尘和噪音大的问题。通过制动钢背与摩擦材料粘接面进行处理避免粗糙度工艺，获得更稳定的质量和高粗糙度配合面的效果。保留产品冲压的外形尺寸精度，平面度精度及一致性，关键尺寸的稳定性均能达到CPK1.67以上的水平。This invention provides a method for treating the high surface roughness of brake steel backing surfaces. Compared with existing technologies, it has the advantages of convenient operation, good operational stability, and high efficiency. It solves the problem of excessive dust and noise caused by increasing the surface roughness of brake steel backing surfaces. By treating the bonding surface between the brake steel backing and the friction material, a roughness process is avoided, resulting in more stable quality and the effect of a high-roughness mating surface. The dimensional accuracy, flatness accuracy, and consistency of the stamped product are preserved, and the stability of key dimensions can reach a level of CPK1.67 or higher.

 实现生产效率提升与平衡生产。新工艺在效率上可以达到每小时1800～2400件，在传统工艺上有10%～30%的提升，满足生产工厂的批量化生产要求；另外采用传送带传送流转和加工省去中间库存或线边库实现平衡生产。由于HRT工艺融于去毛刺工艺中，从整体后处理工艺步序上是减少了生产工艺步序的；另外采用传送带流转和加工减少了工序间堆积时间和线边库的建立，既能减少产品的流转和积压时间，又减少生产人员的投入，因此与传统后处理工艺的生产成本上是有很大优势的。This new process achieves improved production efficiency and balanced production. It can reach an efficiency of 1800-2400 pieces per hour, a 10%-30% improvement over traditional processes, meeting the batch production requirements of manufacturing plants. Furthermore, the use of conveyor belts for transfer and processing eliminates intermediate or line-side inventory, achieving balanced production. Because the HRT process is integrated into the deburring process, the overall post-processing steps are reduced. Additionally, the use of conveyor belts for transfer and processing reduces inter-process accumulation time and the establishment of line-side inventory, thus reducing product turnover and backlog time, as well as reducing the input of production personnel. Therefore, it has a significant advantage in production costs compared to traditional post-processing processes.
