Abstract
The utility model provides a tool used for metal surface treatment, in particular to a welding seam hardening tool. The tool comprises a tool shank (1) and a tool bit along the axial direction, wherein the working face of the tool bit adopts a spherical face. The welding seam is subject to the cold deformation after the pressure application through the spherical face, according to the cold work hardening principle, the hardness of weld metal can be improved, and the weld metal is particularly suitable for the stainless steel welding seam containing alloying elements such as Cr, Ni, Mo and the like. After the welding seam hardening tool is used for processing the welding seam of a repaired wrapper roll, the hardness of the weld metal is improved from HB 210-230 to HRc 52-54, thereby achieving the hardness requirement of the weld metal used on the wrapper roll, and reducing the maintenance cost of a coiling machine greatly.
Description
Technical field
The utility model relates to a kind of cutter that is used for Treatment of Metal Surface, especially a kind of weld seam sclerosis cutter.
Background technology
Welding is fixedly connected, the repair mode of the part of using always, but welds between formed weld seam and the part noumenon, all has certain difference at aspects such as composition, performances, can't satisfy instructions for use in some particular application.
As adopt welding manner that the hot rolling downcoiler is helped winding up roller reparation, according to part noumenon metal and welding requirements, select for use a kind of nickel-based welding wire to join the HJ107 solder flux as resurfacing welding material, the metallographic structure of weld metal is mainly austenite, and contains compound and carbide between little metal.But the hardness of weld metal is very low, only is HB210-230, and this requires HRc52-58 that big gap is arranged with the last machine technology that helps winding up roller.Therefore, can't increase the maintenance cost of coiling machine greatly by built-up welding to helping winding up roller reparation.
The utility model content
In order to overcome existing deficiency, technical problem to be solved in the utility model provides a kind of weld seam sclerosis cutter that can improve weld metal hardness.
The technical scheme that its technical problem that solves the utility model adopts is: weld seam sclerosis cutter, to form by the handle of a knife cutter head vertically, and described cutter head working face is a sphere.
As a kind of preferred version, described cutter head is the spherical ball of rolling and cooperating or be rotatably assorted with the cutter neck.
The beneficial effects of the utility model are: exerting pressure by the sphere butt welded seam causes weld seam generation cold deformation, principle according to flow harden, can improve weld metal hardness and intensity, especially be applicable to the stainless steel weld joint of alloying elements such as containing Cr, Ni, Mo, this helps the winding up roller accessory that significant cold work hardening is arranged.Therefore after the weld seam that reparation is helped winding up roller was handled, the hardness of weld metal was increased to HRc52-54 by HB210-230, thereby can reach the hardness requirement that helps winding up roller to use on the machine, and greatly reduces the maintenance cost of coiling machine.
Description of drawings
Fig. 1 is a front view of the present utility model.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, weld seam sclerosis cutter of the present utility model is made up of handle of a knife 1, cutter head vertically, and described cutter head working face is a sphere.Exerting pressure by the sphere butt welded seam causes weld seam generation cold deformation, improves weld hardness and intensity according to the principle of flow harden, especially is applicable to the stainless steel weld joint of alloying elements such as containing Cr, Ni, Mo, and this metalloid has significant cold work hardening.Therefore after the weld seam that reparation is helped winding up roller was handled, the hardness of weld metal was increased to HRc52-54 by HB210-230, thereby can reach the hardness requirement that helps winding up roller to use on the machine, and greatly reduces the maintenance cost of coiling machine.
Owing to will exert pressure by the sphere butt welded seam, frictional force between sphere and the weld seam is big, the replacing of cutter head for convenience, described handle of a knife 1 comprises cutter neck 2, described cutter head and cutter neck 2 removably connect, and detachable flexible connections such as cooperating, be slidingly matched as rolling or dovetail groove, bolt etc. are detachably fixedly connected.Further, in order to reduce the frictional force between sphere and the weld seam, reduce wearing and tearing, described cutter head is the spherical ball 3 of rolling and cooperating or be rotatably assorted with cutter neck 2.
Concrete, the cutter neck 2 of present embodiment is provided with the cavity that is made of blind hole 21 and the port lid 4 that comprises spacing hole 41, and described ball 3 is arranged in the cavity and with the cavity rolling and cooperates, and described ball 3 is projected to outside the cavity by spacing hole 41.Can certainly adopt the cutter neck of Y font, ball by rotating shaft be arranged on Y font cutter neck opening part and be rotatably assorted with the cutter neck, but this moment rotating shaft relatively poor to the support of ball 3; Perhaps other modes.
During work, axially up and down by face of weld and lowest limit position, blind hole 21 hole, the rock deformation pressure on ball 3 butt welded seam surfaces mainly comes as for the support at the bottom of blind hole 21 holes ball 3, so wearing and tearing are bigger at the bottom of the ball 3, hole, and is difficult to after the wearing and tearing at the bottom of the hole repair.Therefore in order to reduce ball 3 and friction at the bottom of blind hole 21 holes, reduce wearing and tearing, maintain easily, concrete, described blind hole 21 bottoms are provided with the bearing 5 that rolls and cooperate with ball 3.Ball 3 circumferential spacing guaranteed contact position between ball 3 and the bearing 5 and stressed, especially to the left and right spacing can guarantee the stressed along the left-right symmetry axis of bearing 5 week, thereby guarantee the durable of bearing 5, therefore surface, further described bearing 5 outer ring is provided with the groove that adapts with ball 3 shapes.
During work, ball 3 is circumferentially undertaken spacing by blind hole 21 inwalls, spacing hole 41 hole walls or both combinations.But lid 4 stressed easy deformation, in order to guarantee the circumferentially spacing, concrete of ball 3, the ball 3 of present embodiment is circumferentially spacing by blind hole 21 inwalls, and lid 4 mainly plays the effect that prevents that ball 3 from coming off, and during work, lid 4 breaks away from ball 3.But with identical at the bottom of the hole, be difficult to equally after blind hole 21 inner wall abrasion repair, therefore further for convenience of the maintenance of cutter, be provided with the stop collar of tubulose in the described blind hole 21, described stop collar is fixed by blind hole 21 walls and is cooperated with ball 3 rollings.Concrete, described stop collar is a copper sheathing 6, compares little, the good heat dissipation of friction of copper with the stop collar of other materials.
