Description
Technical Field
The invention relates to the field of non-traditional mechanical polishing processing, which is used for clamping a linear pipe to be processed and forming a flow channel with good sealing performance so as to ensure that an abrasive medium does not leak in the flowing process of the linear pipe to be processed.
Background
Abrasive flow machining is a non-traditional mechanical polishing method that extrudes a polymer-based or water-based medium mixed with abrasive particles through the surface to be machined to achieve a finishing process. In the abrasive particle flow processing process, the effect of the abrasive particles on the surface to be processed can be divided into stages of scratching, plowing, cutting and the like. Under the action of hydraulic pressure or air pressure, the polymer-based or water-based abrasive medium flows back and forth in a flow passage formed by the workpiece to be processed and the clamp, and the fluid characteristic of the abrasive medium ensures that the abrasive medium is self-adaptive to the surface to be processed, so that the surface to be processed of the workpiece is polished.
Sealing is a measure to prevent leakage of fluid or solid particles from between the bonding surfaces of the sealing structure and to prevent intrusion of foreign substances such as dust and moisture into the interior of the apparatus. Leakage is a not negligible quality problem of mechanical equipment, affects normal operation, working efficiency, service life and the like of the equipment, and can cause energy waste and environmental pollution. The sealing performance is an important index for evaluating the performance and quality of equipment. According to statistics, 60% of unplanned parking accidents of chemical enterprises are related to sealing failures. In the polishing of the abrasive particle flow of the linear tube, the clamp plays a role in sealing the flow channel and fixing the linear tube to be processed. When the viscoelastic characteristic effect of the abrasive medium is weak, the phenomena of abrasive material 'running', 'overflowing', 'dripping' and 'leaking' are caused by weakening of the sealing effect of the clamp, and then the normal polishing of the linear pipe fitting is influenced, and the stability of the polishing process is influenced. For water-based abrasive media, a highly sealed fixture is critical to achieving a relatively stable polishing process.
Although the existing linear pipe clamp sealing technology has a certain effect, for polymer-based abrasive media and water-based abrasive media with low viscoelastic effect, the existing clamp sealing design still has certain limitations in the aspects of high sealing performance, leakage prevention, no deformation in the polishing process of the linear pipe and the like, and has a plurality of problems.
In addition, the existing linear pipe clamp sealing technology is poor in applicability, and different special clamps are required to be adopted for different types of linear pipes. When the linear pipe parts have different lengths and different length-diameter ratios, the number of the required special clamps is large, so that the resource waste and the economic efficiency are poor.
