The reference numbers in the figures are as follows: 1. the multifunctional knife comprises an operating handle, 2 parts of a multifunctional knife head, 2-1 parts of a knife tip, 2-2 parts of a linear type knife edge, 2-3 parts of an arc-shaped knife edge.
Detailed Description
The utility model provides a scraper for cleaning dirt on the surface of a plastic welding part, which can effectively clean dirt and an aging layer on various irregular welding surfaces of the plastic welding part, avoid welding defects caused by unclean surface scraping or an aging layer on the surface of a welding part during the welding maintenance of plastic equipment in a cold rolling and pickling process section, and provide reliable quality guarantee for the welding of the plastic equipment.
Referring to fig. 1, 2 and 3, the present invention comprises an operating handle 1 and a multifunctional cutter head 2 connected to each other, wherein the multifunctional cutter head 2 has a plate shape, and a cutter point 2-1, a linear blade 2-2 and an arc blade 2-3 are provided on the multifunctional cutter head 2. Two linear blades 2-2 are provided, which are respectively provided at both sides of the blade tip 2-1, two arc blades 2-3 are provided between the two linear blades 2-2, and two arc blades 2-3 are provided, one is a concave arc blade (shown in fig. 1 and 2) for scraping a convex arc surface, and the other is a convex arc blade (shown in fig. 3) for scraping a concave arc surface. The multifunctional cutter head with the concave arc-shaped cutting edge is called an inner circle sharp-edged cutter head, and the multifunctional cutter head with the convex arc-shaped cutting edge is called an outer circle sharp-edged cutter head.
The size of the inner circle sharp edge tool bit and the size of the outer circle sharp edge tool bit can be determined according to the size of a welding device part as required, the size and the shape of the operating handle 1 can be determined as required, and the operation is convenient, comfortable and efficient. The multifunctional cutter head with the corresponding shape is selected according to the shape of the welding part of the plastic equipment for scraping, the cutting edge of the multifunctional cutter head 2 is sharp for ensuring the scraping quality, and the angle of the cutting edge is not too small so as to avoid the breakage of the cutting edge.
All parts are made manually, the multifunctional tool bit 2 is recommended to be manufactured by purchasing a 440C steel plate with higher hardness and stronger corrosion resistance, the operating handle 1 can be replaced by a common thin iron rod or a waste screwdriver, and the manufacturing cost is lower.
The inner circle sharp blade tool bit is cut into an equilateral triangle with required size by using a 440C plate with the thickness of 3mm, one side of the tool bit is polished into an inner circle radian with the diameter of 200mm by using a grinding wheel with the diameter of 200mm, and then three sides of the tool bit are polished to form blades by using the grinding wheel; the outer circle sharp edge tool bit uses a 440C plate with the thickness of 3mm to cut, the included angle of two straight edges is 60 degrees, the other edge is polished into an outer circle radian with the diameter of 50mm, and then the three edges of the multifunctional tool bit are polished out of the cutting edge by using a grinding wheel. The two scrapers are manufactured by respectively welding the scrapers and the operating handle together through a cold welding technology.
Because the multifunctional cutter head part is smaller, a grinding wheel with high reliability, slower rotating speed and smaller power is selected for grinding when the cutting edge is ground, grinding personnel needs to have rich experience and protect the cutting edge in place, and the annealing phenomenon caused by overheating of the cutter head due to grinding is avoided while safety is paid attention to during grinding.
The cold welding technology is selected when the multifunctional cutter head is welded with the operating handle, so that the annealing phenomenon caused by overheating of the multifunctional cutter head is avoided.
The cold-rolling and acid-washing device has a reasonable structure, can bring great help to the daily maintenance, overhaul and other welding works of cold-rolling and acid-washing process section plastic equipment, realizes effective scraping of the surface of a plastic welding part, avoids causing welding defects, greatly improves the welding quality, and ensures the stability and the service life of the plastic equipment.
When the plastic equipment is welded by hot air melting in the cold rolling and pickling process section, the impurities and the dirty parts on the surface of the welded part are cleaned by the two scrapers so as to prevent the welded part from forming an interlayer due to the impurities and the aged layer. Practice proves that the method solves the problem that 90% of plastic equipment in the cold rolling and pickling process section of our unit has welding defects due to incomplete scraping or the part which cannot be scraped, saves a large amount of overhaul time, reduces the equipment failure rate, reduces the cost consumption of spare parts, and prolongs the service life of the equipment. The utility model has the advantages of low price of required materials, convenient processing, strong practicability and obvious brought effect.
