Abstract
The utility model discloses an inner scraping cutter for aluminum welded pipe welding joint burs. A scraping cutter body is fixed at one end of a cutter rod through a screw, the portion, on the cutter rod, of the cutter edge of the scraping cutter body is provided with a chip removal opening, and the chip removal opening is communicated to the end opening of the cutter rod through a chip removal channel; a plurality of groups of supporting steel balls are arranged in the hollow cutter rod, each group of supporting steel balls comprise three supporting steel balls, the three supporting steel balls in each group are arranged staggered left and right and all extruded by screws to be arranged in small holes in the wall of the cutter rod, and the cutter rod is supported in a cavity of an aluminum welded pipe by the steel balls; a pin shaft used for connection is arranged at the other end of the cutter rod, and the cutter rod is connected to a cutter rest brand archway through the pin shaft. The cutter rod is supported in the cavity of the aluminum welded pipe through the multiple groups of the supporting steel balls, and therefore the situation that the aluminum welded pipe is rubbed and even damaged by deformation of the cutter rod is prevented. In use, the aluminum welded pipe is instantly cooled after being formed in a welded mode, the scraping cutter body starts to scrap the burs on the inner side of an aluminum welded pipe welding joint when the aluminum welded pipe is pushed forward, and scraped chips enter the chip removal channel through the chip removal opening and then are discharged out through the end opening of the cutter rod.
Description
Technical field
The utility model relates to a kind of aluminium welded tube process equipment, specifically relates to a kind of interior type scraping knife of aluminium welded tube welding seam burr.
Background technology
The seamless aluminium tubing processing technology is loaded down with trivial details, and production cost is very high, has restricted its marketing, and the production cost of seamed aluminum pipe is far below seamless aluminium tubing, and along with the improvement of processing technology, seamed aluminum pipe performance improves constantly, and can substitute most of seamless aluminium tubing.Usually with interior type scraping knife, carrying out the burr of scraping aluminium welded tube welding seam inner surface in the processing technology of seamed aluminum pipe is overlap, make it smooth, need to after high-frequency welding is cooling, carry out immediately shaving effect just best, in the production equipment of existing seamed aluminum pipe, interior type scraping knife is few, structural design is also unreasonable, causes the inner surface flatness of ratio-frequency welding aluminium welded tube welding seam poor, even affects the result of use of seamed aluminum pipe when serious.
Summary of the invention
The utility model is mainly to solve the existing technical problem of above-mentioned prior art, and a kind of interior type scraping knife of aluminium welded tube welding seam burr is provided.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of interior type scraping knife of aluminium welded tube welding seam burr, comprise knife bar, one end of described knife bar is fixed with type scraping knife through screw, be provided with some groups in the knife bar of hollow and support steel ball, every three support steel balls are one group, via steel ball, knife bar is supported in the cavity of aluminium welded tube, the other end of knife bar is provided with the bearing pin for connecting.
As preferably, about three support steel balls of described every group, shift to install, by the screw extruding, be arranged on the aperture on knife bar bar wall.
As preferably, the knife-edge part of described type scraping knife is provided with chip removal mouth on knife bar, and chip removal mouth is communicated to the port of knife bar through channel of chip removal.
The utility model practicality is organized the support steel ball more and knife bar is supported in the cavity of aluminium welded tube, prevent that knife bar is out of shape friction and even damages the aluminium welded tube, cooling immediately after the moulding of aluminium tube-welding during use, along with the aluminium welded tube is pushed forward, type scraping knife is offered the burr of scraping aluminium welded tube welding seam inboard, the chip of scraping enters channel of chip removal through chip removal mouth and then emits through the port of knife bar, has the characteristics such as simple in structure, reasonable in design.
The accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model;
Fig. 2 is a kind of use status architecture schematic diagram of the present utility model;
Fig. 3 is the A-A sectional structure schematic diagram of Fig. 2.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: referring to Fig. 1～3, in the utility model, an end of knife bar 1 is fixed with type scraping knife 2 through screw 3, and the knife-edge part of type scraping knife 2 is provided with chip removal mouth 4 on knife bar 1, and chip removal mouth 4 is communicated to the port of knife bar 1 through channel of chip removal 7; Be provided with some groups in the knife bar 1 of hollow and support steel ball 5, every three support steel balls 5 are one group, three support steel ball 5 left and right of every group shift to install, and by screw 11 extruding, are arranged on the aperture 12 on knife bar bar wall, via steel ball, knife bar 1 are supported in the cavity of aluminium welded tube 8; The other end of knife bar 1 is provided with the bearing pin 6 for connecting, and through bearing pin 6, knife bar is connected on the knife rest memorial archway.The utility model practicality is organized support steel ball 5 more and knife bar 1 is supported in the cavity of aluminium welded tube 8, prevent that knife bar 1 is out of shape friction and even damages aluminium welded tube 8, cooling immediately after the moulding of aluminium tube-welding during use, along with aluminium welded tube 8 is pushed forward, type scraping knife 2 is offered the burr 9 of scraping aluminium welded tube welding seam 10 inboards, the chip of scraping enters channel of chip removal through chip removal mouth and then emits through the port of knife bar, has the characteristics such as simple in structure, reasonable in design.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, and many distortion can also be arranged.Any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all should think and belong to protection domain of the present utility model.
