Description
Technical field
The utility model relates to alloy cutter technical field, specifically a kind of weld seam scraper.
Background technology
In Plate Welding, steel band welding, in steel-pipe welding technical field, need to use scraper butt welded seam to process, its requirements is, by once or several scraping, is patted commissure whole.
Mostly current scraper is single-blade, namely a cutter only has one or two blade, as shown in Figure 7, more can only renew after blade destroys completely, cause a kind of waste of raw material.
Utility model content
The purpose of this utility model is to provide a kind of weld seam scraper, first has four blades, can use four times, reduces the consumption of scraper, is secondly divided into row to blade part and improves, and improves efficiency and the quality of weld seam process, is convenient to install and use at this.
The technical scheme in the invention for solving the technical problem is: a kind of weld seam scraper, comprises scraper body, it is characterized in that, described scraper body has:
The first surface that be set parallel to each other and profile is identical and second, the square that described first surface profile is made up of four sections of curved lines, described first surface and the second face be centrosymmetric on the projection surface arrange and diagonally miss one another, and first surface and second towards lean out outward and near described curved line face on be provided with groove;
And through scraper body center of gravity and perpendicular to the fixing hole on two sides.
Further, described fixing hole is for diminish gradually and symmetrically arranged conical bore towards centre from two.
Further, described fixing hole is square opening.
Further, in described scraper body first surface and the second face diagonally miss one another formed prism angle of inclination be 60 degree.
Further, the section configuration of described groove is the check mark shape of deepening gradually inside lateral.
Further, the radius of described curved line is 100mm.
The beneficial effects of the utility model are:
This cutter is provided with the blade of four arcs, and coordinates the profile design of cutter body, can divide four uses, and be independent of each other, and each use blade, is equivalent to four scrapers, reduces the consumption of scraper.
Arranging of groove has curling function to scraping welding wire, avoids causing secondary damage to the surface of steel band.

Detailed description of the invention
As shown in Figures 1 to 6, a kind of weld seam scraper, comprises scraper body, the effigurate cutter of tool that scraper body adopts high hardness alloy steel to be formed through forging and stamping, heat treatment and grinding.
Described scraper body has:
The first surface 1 that be set parallel to each other and profile is identical and the second face 2, the square that first surface 1 profile is made up of four sections of curved lines, the square that second face 2 profile is made up of four sections of curved lines, the profile in two faces is identical, but in arranged direction, described first surface 1 and the second face 2 are centrosymmetric on the projection surface and arrange and diagonally miss one another, that is, as shown in Figure 1, along the diagonal of first surface or second, the prism 3 of side is obliquely installed, general angle of inclination is in the scope of 45 degree to 80 degree, best angle of inclination is 60 degree, form operator face 4, rear knife face 5 and blade 6, wherein first surface and second conduct operator face use, the face tilted is rear knife face 5, because blade 6 is arcuate lien segments, the radius of curved line is generally at about 100mm, after the namely arcwall face of knife face 5 correspondence, rear knife face can carry out grinding.When carrying out the process of weld seam, mainly blade carries out scraping.For reaching best effect, after reconditioning during knife face 5, the tru(e)ing face dodged 51 can be formed, as shown in Figure 5.
And first surface and second towards lean out outward and near blade (curved line) face on be provided with groove 7; Also can be called chip-breaker, chip can reverse in a groove, and plays the effect of chip breaking, prevents metal fillings from destroying the weld seam hung or surface.
The section configuration of groove 7 is what deepen gradually inside lateral, and shape is similar to check mark shape, and groove and blade have certain distance, such as 1 millimeter, reserve the consumption of sharpening.
A fixing hole 8 for fixed doctor, this fixing hole passes scraper body center of gravity and perpendicular to two sides, can be fixed it easily like this.The shape of above-mentioned fixing hole can, for diminish gradually and symmetrically arranged conical bore towards centre from two, as Fig. 1, can be also square opening, as Fig. 6.
Using method is:
As shown in Figure 8, first this scraper is arranged on handle of a knife, handle of a knife 9 is for scraping a part for bits equipment, it is execution unit, during installation, a blade (being labeled as the first blade) of this scraper is towards weld seam part 10, and that is the steel plate of blade and pending weld seam is tangent, then carry out scraping bits operation, what generally can complete weld seam by three feedings strikes off process.
When the first edge wear to a certain extent after, change the direction of scraper, use new blade (being expressed as the second blade) to carry out scraping bits.
Circulate successively, when all four blades are all the corrections with carrying out blade after completing, until blade is scrapped completely.
This four swords scraper can circulate, use in batches, greatly reduces the consumption of scraper.
Except the technical characteristic described in description, be the known technology of those skilled in the art.
