Abstract
The invention discloses an on-line repairing method of an on-axis conical surface, which comprises the following steps: (1) processing a combining cap for standby, and processing a half cone sleeve for standby; (2) uniformly coating red egg powder on the conical surface of the shaft of the scrap cutter, matching the half cone sleeve prepared in the step and covering the half cone sleeve on the conical surface for grinding, and performing surfacing treatment and grinding on the part with the red egg powder on the conical surface after grinding is finished; repeating the steps until the area of the red egg powder on the conical surface is less than 10% of the area of the conical surface after grinding. Compared with the prior art, the invention does not need workers to disassemble and assemble the box body and parts on the shaft, thereby ensuring the assembly precision inside the original box body; timeliness: finding and repairing in time; the time is short: can be finished in 8 hours, for example, the operation of dismantling the box body and conveying the box body for processing only needs more than 4 days.
Description
Technical Field
The invention belongs to the field of machinery, and particularly relates to an on-line repairing method for an on-axis conical surface.
Background
The existing scrap cutter box body is fixedly arranged on the ground of a foundation by using footing screws, the weight of the box body is 30T, and connecting pieces connected with the box body are provided with universal couplings, various oil pipes, sensors and the like, so that the box body is generally not detached for maintenance and is maintained on line. As shown in the first figure, a schematic diagram of the repair of the shaft of the scrap cutter is that the box body 1 of the scrap cutter is installed on a base surface, the head of the scrap cutter shaft 2 is a conical surface, and a cutter head for shearing steel plate edge wires is installed on the conical surface, so that the conical surface is easily worn due to insufficient vibration, stress and maintenance at the position, and the cutter head is changed in shearing time gap, so that normal production cannot be performed.
Disclosure of Invention
The invention aims to solve the technical problem of providing an on-line repairing method of an on-axis conical surface so as to solve the problems of poor effect and the like in the prior art.
In order to solve the technical problems, the technical scheme adopted by the invention is as follows:
an on-line repairing method for an axial conical surface comprises the following steps:
(1) processing a combined cap for standby, and processing a semicircular taper sleeve for standby;
(2) uniformly coating red egg powder on the conical surface of the crushing cutter shaft, matching the semi-conical sleeve prepared in the step (1) and covering the semi-conical sleeve on the conical surface for grinding, and performing surfacing welding treatment and grinding on the part with the red egg powder on the conical surface after grinding is finished; repeating the steps until the area of the red egg powder on the conical surface is less than 10% of the area of the conical surface after grinding.
The size of the inclined plane of the semi-conical sleeve is matched with the conical surface of the chopping knife shaft, and the straight hole of the semi-conical sleeve is matched with the outer circle of the combining cap.
Wherein, the excircle diameter of the nut is 254 mm.
Wherein, the diameter of the minimum diameter excircle of the half cone sleeve is 258 mm.
Wherein the width of the combining cap is 60 mm.
Has the advantages that:
compared with the prior art, the invention has the following advantages: the conical surface of the on-line repaired chopping cutter shaft and the matched cutter head meet the requirements on use and assembly precision, the cutter head is not loosened too much, the gap between the chopping blades is stable, and the shearing precision meets the requirements. The method has the advantages that: the box body and parts on the shaft are not required to be disassembled and assembled by workers, so that the assembly precision of the interior of the original box body is ensured; timeliness: finding and repairing in time; the time is short: can be finished in 8 hours, for example, the operation of dismantling the box body and conveying the box body for processing only needs more than 4 days.

Detailed Description
Example 1
As shown in fig. 1, the position of the conical surface on the chopping knife shaft 2 is a surface to be repaired. As shown in fig. 3, a combined cap is processed, the screw teeth of the combined cap are matched with the chopping knife shaft 2, and the outer circle of the combined cap
Minimum diameter of conic surface
2mm smaller and the cap width is about 60 mm. As shown in fig. 3, a complete taper sleeve is firstly processed, and the sizes of inner holes such as the taper, the diameter and the length of a small head of the taper sleeve are consistent with the taper on the chopping knife shaft; the size of the straight hole is consistent with that of the outer circle of the combining cap; line is sleeved on the taperThe cutting into two halves is just the half taper sleeve for grinding, and the size is guaranteed and the use is convenient by using the half taper sleeve for grinding. After the two auxiliary tools are machined, a certain level of welding and polishing personnel is selected for surfacing and polishing by utilizing the maintenance time of 8 hours. Surfacing and grinding, as shown in figure 2, uniformly coating red egg powder on a surface conical surface, matching a semi-conical sleeve 3 on a combining cap 4 and abutting against a small step 5, grinding the semi-conical sleeve 3 on a conical surface, and taking down the semi-conical sleeve after grinding; and (3) performing surfacing welding on the part with red powder on the conical surface, polishing by using a polishing machine and a polishing machine, coating red egg powder, performing matched grinding and surfacing welding, and repeating the multi-pass surfacing welding grinding until the area of the red egg powder on the conical surface is less than 10%. The size of the conical surface repaired by the method can basically meet the use requirement.
In 2017, in 4 months, the conical surface of the chopping cutter shaft and the matched cutter head which are repaired on line by using the method meet the requirements on the use and assembly precision, the cutter head is not loosened too much, the gap between the chopping blades is stable, and the shearing precision meets the requirements. The method has the advantages that: the box body and parts on the shaft are not required to be disassembled and assembled by workers, so that the assembly precision of the interior of the original box body is ensured; timeliness: finding and repairing in time; the time is short: can be finished in 8 hours, for example, the operation of dismantling the box body and conveying the box body for processing only needs more than 4 days.
