and step S4, starting the driving parts simultaneously, so that the cutting line 6 moves on the surface of the workpiece 1, and the clamping assembly moves up and down simultaneously, thereby finishing the processing of the guide groove on the surface of the workpiece 1.
Optionally, before the surface guide groove processing is performed on the workpiece 1, a corresponding cutting line 6 is further selected according to the surface guide groove shape of the workpiece 1 to be processed, the shape of the cutting line 6 is consistent with the shape of the groove to be processed on the surface of the workpiece, the groove shape of the cutting line is as shown in fig. 9 and can be a trapezoid, a V-shape or a U-shape, the wire body 61 can be made of metal wire or nylon wire, the abrasive grains 62 bonded on the surface of the cutting line 6 can be abrasive grains with higher hardness such as diamond, silicon carbide, aluminum oxide and the like, the grain size of the abrasive grains 62 is 1-10 μm, and the bonding mode of the abrasive grains 62 and the wire body 61 can be organic bonding, vapor deposition, electroplating and the like.

Optionally, step S3 specifically includes: the wedge-shaped blocks at the two ends of the tensioning wheel 5 are adjusted, so that the center height of the tensioning wheel 5 is changed, and the surface pressure of the cutting line is adjusted.
Optionally, step S4 specifically includes: simultaneously starting each driving piece, paying off the cutting line 6 from the paying-off shaft 313, and forming guide grooves with the same shapes as the cutting line 6 on the surface to move directionally under the driving of the driving guide roller 313 so as to finish the processing of the surface of the workpiece 1; the cutting wire 6 finally enters the wire take-up pulley 423, the cutting wire 6 on the pay-off shaft 413 is reduced along with the increase of the processing time, the cutting wire 6 on the take-up pulley 423 is increased, when the cutting wire 6 on the pay-off shaft 413 is used up soon, all the driving members move in reverse directions, the functions of the pay-off assembly 41 and the wire take-up assembly 42 are replaced at the moment, in order to ensure that the tension of each cutting wire 6 is uniform, the rotation of each rotating movement member should be synchronous, and the movement speed of the cutting wire 6 is between 1 and 15 m/s.
Optionally, a large amount of heat is generated by friction between the cutting line 6 and the surface of the workpiece 1 during the machining process, and in order to avoid damaging the rubber workpiece due to overheating, a cold cutting fluid (fig. 10) can be used in the machining area to reduce the temperature of the machining surface and simultaneously flush the machining surface, wherein the flow rate of the cooling fluid is 30-100mL/min, and the machining area is ensured to be completely soaked by the cooling fluid.
Optionally, the cooling liquid can be oil-based cooling liquid or water-based cooling liquid, and if water-based cold cutting liquid is used, a certain proportion (2-5 mass percent) of antioxidant can be added to prevent the water-based cooling liquid from being oxidized and deteriorated and corroding workpieces and equipment.
Optionally, when the cooling liquid is used, a corresponding cooling liquid circulating system is further required for recycling the cold cutting liquid, a driving piece of the circulating system can be a peristaltic pump, the peristaltic pump has the advantages of adjustable flow, convenience in replacement and the like, and the peristaltic pump can also be driven by other mechanisms as long as the circulation of the cooling liquid can be realized.
Optionally, the cooling liquid circulation system includes a filter for filtering chips generated during processing and abrasive particles 62 falling from the cutting line 6, so as to prevent such impurities from entering the processing area along with the cooling liquid, and generating scratches in the guide groove, which affects the surface quality of the guide groove, the filter may be a common filter element with a filtering diameter of 1 μm, or other filters may be used, as long as the filtering of the cooling liquid can be realized.
By adopting the method and the device, the simultaneous processing of the multiple surface guide grooves on the guide roller with the multiple surface guide grooves can be realized, the processing efficiency of the guide grooves on the surface of the workpiece 1 is improved, and meanwhile, the consistency of the guide grooves can be well ensured.
