Embodiment Construction

[0013] Such as figure 1 As shown, the roller 1 and acupuncture 2 are made of special high-quality carbon structural steel materials, and the acupuncture 2 is positioned and welded to the roller 1 by the stud welding method, so that the bottom surface of the acupuncture 2 is fixed to the surface of the roller 1 connection; see figure 2 , using argon arc welding to spot weld and strengthen the connection edge 3 between the acupuncture 2 and the roller 1 .

[0014] Stud welding parameters: 92V, capacitance 132000μF, welding spring pressure 32N, welding time 0.03 seconds, welding penetration 0.6mm.

[0015] Argon arc welding process parameters: argon gas pressure 0.05 ~ 0.07MPa, welding current 45 ~ 55A.

Abstract

The invention discloses a manufacturing method of licker-in used for a fiber board felting machine. Acupuncture is positioned and welded on a roller by using a stud welding method to lead the bottom surface of the acupuncture to be fixedly connected with the surface of the roller, and then argon arc welding is adopted to close and strengthen the connecting edge of the acupuncture and the roller through spot welding. By adopting the manufacturing method, the diameter of an acupuncture welding position is increased, the welding strength is strengthened, conical surface transition is adopted between the acupuncture welding position and an acupuncture working position, and transition positions all adopt round corner transition so as not to produce stress concentration. The strength of the connecting surface between the bottom surface of the acupuncture and the surface of the roller reaches 156MPa, thus improving the bonding strength between the acupuncture and the roller by 4-8 times; furthermore, the processing operation is simple, the cost is low, the speed is high, the welding quality is stable and firm, and simultaneously the processed licker-in has good safety, and the breaking and falling of the acupuncture do not occur.

Description

technical field [0001] The invention relates to a method for manufacturing a licker-in roller for a fiberboard paving machine, which belongs to the technical field of wood production machinery. Background technique [0002] There are two known processing methods for existing licker-in rollers used in wood-based panel paving. One is to directly weld ordinary needles on the surface of the roller, and weld the needles on the surface of the roller through side spot welding. There is no welding surface between the bottom surface of the roller and the surface of the roller, so the connection strength is not high. The disadvantage of this method is that the ordinary welding is not strong enough, and it is easy to fall off after being stressed. The other is to process dovetail grooves on the surface of the roller, and then fix the acupuncture into the dovetail grooves with additional devices. The disadvantage of this processing method is that the processing technology is complicated...
