The invention provides a diamond wire bus and a diamond wire, the diamond wire bus comprises a base body and a coating layer covering at least part of the surface of the base body, the coating layer comprises a first metal layer, and the first metal layer covers at least part of the surface of the base body; the second metal layer covers at least part of the surface, far away from the substrate, of the first metal layer; the third metal layer covers at least part of the surface, far away from the first metal layer, of the second metal layer; wherein the first metal layer comprises first metal, the second metal layer comprises second metal, and the third metal layer comprises third metal and fourth metal; the content of third metal in the third metal layer increases progressively in the direction away from the second metal layer; the fourth metal and the second metal are the same metal. The outer surface of the third metal layer can keep sufficient strength and cannot fall off while achieving a lubricating effect, and the inner surface of the third metal layer is combined with the second metal layer, so that the cutting process of hard and brittle materials can be continuously carried out, and the cutting yield is improved.

The invention relates to the technical field of steel structure welding, in particular to a heavy-load workshop box-shaped steel structure welding structure and method.The heavy-load workshop box-shaped steel structure welding structure comprises a base, four mounting grooves are circumferentially formed in the upper surface of a table body, first threaded rods are horizontally and rotatably mounted in the mounting grooves, and the first threaded rods are sleeved with sliding blocks in a threaded mode; a clamping opening is horizontally formed in the surface of the sliding block. And a second threaded rod is rotatably installed on the surface of the sliding block, the second threaded rod is sleeved with the sliding block in a threaded mode, one ends of the two inserting rods are fixedly connected with the surface of the sliding block, and clamping plates are fixedly installed at the ends, away from the sliding block, of the two inserting rods. Butt joint and fixing of a plurality of steel structure plates with different thicknesses can be rapidly completed, practicability is improved, meanwhile, the tedious steps of fixing the plates and removing the fixed plates do not need to be repeated, different gaps can be changed to correspond to the positions of a welding mechanism, and the box type steel structure welding machining efficiency is improved.

The invention belongs to the technical field of battery foils, and particularly relates to an aluminum foil cutting method and a method for reducing radial chromatic aberration of an aluminum foil roll end face. The method comprises the steps that aluminum foil is conveyed to a cutter groove roller, and a rotating disc cutter cuts the aluminum foil; and lubricating liquid is sprayed to the surface of the disc cutter. The lubricating liquid is sprayed to the surface of the disc cutter when the aluminum foil is cut, lubrication is enhanced, the abrasion degree of the cutting edge is reduced, the abrasion difference between the cutting edge in the later stage and the cutting edge in the early stage is small, and therefore the whole cutting face of the obtained aluminum foil roll is smooth and low in roughness, looks bright after mirror reflection is generated, and no dark area exists.

The application discloses a kind of chemical fiber spinning system roll body cleaning device and spinning system, including, support component, be set in the roll body around scrollable;Cleaning component is connected with support component, and cleaning component is contacted with the lateral wall of roll body;Spray component is connected with support component or cleaning component, for spraying lateral wall and / or cleaning component of roll body.The beneficial effects brought by the application: by increasing spraying device, the humidity of the contact surface of roll body and cleaning component is improved, the temperature of cleaning component and lateral wall of roll body is prevented from rising, the antistatic effect is improved, and the lubricating effect is played, the friction between the surface of cleaning component and roll body is reduced, and then the wear between the two is reduced, so that the surface finish of roll body remains good, and the needs of long-period production operation are satisfied.

The utility model discloses an anti-abrasion eccentric shaft motor structure which comprises a cutter shell part, a pneumatic motor is fixedly installed on the outer wall of one side of the top end of the cutter shell part, an eccentric shaft body is fixedly installed at the output end of the pneumatic motor, the interior of the eccentric shaft body is designed to be of a hollow structure, and an oil injection opening is formed in the front end of the eccentric shaft body. According to the solid eccentric shaft, the interior of an existing solid eccentric shaft is broken through to form the internal oil storage groove, so that lubricating oil can be injected and stored, in the continuous injection process, the oil storage groove is formed in the eccentric shaft body, the oil storage groove is formed in the eccentric shaft body, and the oil storage groove is communicated with the oil storage groove. The oil liquid finally overflows through the oil outlet hole, the overflowed oil liquid has a lubricating effect on the contact surface of the eccentric shaft and the ball bearing, and the contact friction effect between the eccentric shaft and the ball bearing can be effectively reduced through the injected lubricating oil, so that the abrasion degree between structures is reduced and delayed, and a certain using effect of lubrication and abrasion resistance is achieved.
