Abstract
The utility model discloses a roll pass turning tool, which pastes a carbon steel arbor (1) with a hard ally blade (2) by brazing. The manufacturing method is that: the carbon steel arbor (1) goes through machining blade groove, cleaning and is brazed with the hard alloy blade (2). The pass turning tool is of the same width, and saves alloy steel. The roll pass turning tool has relatively high wearability, the hard alloy blade is high in hardness and long in service life, the comprehensive service life is higher than high speed steel roll pass blade by three to five times. The roll pass blade is applicable in turning 70Mn cast steel rollers, nodullar iron rollers, chilled cast iron rolls, semi-steel forging rolls, high-Ni-Cr rolls, surfacing rolls and so on.
Description
Technical field
The utility model relates to a kind of cutter of metal processing usefulness, especially relates to a kind of lathe tool for roll calibre of special roller lathe.
Background technology
At present, lathe tool for roll calibre generally adopts knife bar and high speed steel W 18Cr4V alloy blade welding or knife bar and high-speed steel alloy blade borax and ferromanganese powder high temperature bonding.The pass lathe tool is not wide at width, and as shown in Figure 1, the alloy blade wider width uses the alloy amount more.Chinese patent notification number 1007966, on July 31 1991 day for announcing, name is called the method for production that discloses the compound form tool of a kind of high-speed steel in the preparation method of the compound form tool of a kind of high-speed steel.Be to make the high-speed steel composite plate by rolling or blast complex method, through steps such as plasma cutting, machined, aligning, heat treatments, make high-speed steel composite plate cutter again with high-speed steel and straight carbon steel.The high-speed steel roll pass lathe tool hardness of making of above-mentioned several method is low, wear no resistance, the cutting ability of high-speed steel tool is not as hard alloy cutter, and stock-removing efficiency is lower, the cutting high-hardness roller, as high Minvar roll, ferrosteel roll, then high-speed steel tool is difficult to be competent at.Therefore, be necessary that breaker roll pass lathe tool improves.
Summary of the invention
Technical problem to be solved in the utility model is, easily wearing and tearing and alloy blade wide use steel alloy many problem low at high-speed steel roll pass lathe tool hardness, a kind of hardness height is provided, lathe tool for roll calibre with high-wearing feature, this lathe tool for roll calibre adopts the high carbide chip of hardness, the narrower pass turning insert of carbide chip width is wide at width, the use steel alloy is few, can also save nearly half steel alloy when the assurance wear surface is constant.
The technical solution of the utility model is; A kind of lathe tool for roll calibre, form by carbon steel knife bar and carbide chip, soldering carbide chip on the carbon steel knife bar, the carbon steel knife bar is by carbon steel manufacturing or worn out lathe tool for roll calibre, carbide chip width 15-35mm, the pass lathe tool is wide at width, and carbide chip thickness is 6mm or more than the 6mm, carbon steel knife bar cutter groove and carbide chip cooperation place roughness are more than 5.Opening the 4-8 bar wide on the cutter groove is 2.5mm ditch 3 deeply respectively, with carbide chip contacts side surfaces position step 4 is arranged on knife bar, is a faying face between carbon steel knife bar and carbide chip.
Lathe tool for roll calibre of the present utility model compared with prior art, advantage is that to reduce the alloy blade consumption few, it is good to have high hardness wearability, especially red hardness, long service life.Improve 3~5 times than high-speed steel roll pass lathe tool its comprehensive service life, and this lathe tool for roll calibre is applicable to turning 70Mn cast steel roll, spheroidal graphite roll, chilled cast iron roll, ferrosteel roll, high-ni-cr roll, surfacing roll etc.

Fig. 7 is carbide chip figure.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, shown in Figure 7, select carbon steel knife bar 1, soldering carbide chip 2 on carbon steel knife bar 1, carbide chip 2 thickness are 10mm, the pass lathe tool is wide at width, carbide chip width 25mm, carbon steel knife bar and carbide chip cooperation place roughness 5, carbon steel knife bar 1 are steel plate or worn out lathe tool for roll calibre.Opening the 4-8 bar wide on the cutter groove is 2.5mm ditch 3 deeply respectively, with carbide chip contacts side surfaces position step 4 is arranged on knife bar, is a faying face between carbon steel knife bar and carbide chip.
Manufacturing of the present utility model, the method for repairing this lathe tool for roll calibre are as follows:
1) lathe tool for roll calibre carbon steel knife bar 1 lip-deep oxide is cleaned down, with the bonding position of acetone difference cleaning roller pass lathe tool, carbide chip 2;
2) scolder is put into insert groove, sprinkle borax equably, put carbide chip, weld the place of meeting except that sprinkling one deck borax again at carbide chip end face and side, lathe tool for roll calibre is put into heating furnace, slowly heat up when treating that cutter is heated to brazing temperature earlier during heating, brazing temperature is higher 40 ℃ than scolder fusing point, one side keeps temperature simultaneously to carry out deslagging, during deslagging, with red copper bar carbide chip is moved back and forth 3 times along the groove nest, to get rid of slag in the weld seam by the time occurred copper liquid on the blade of red heat, take out carbide-tipped lathe tool, correction position compresses blade and then sends to tempering;
3) put into 230 ℃ of stove tempering 7 hours after the soldering immediately.
Claims (3)
1, a kind of lathe tool for roll calibre, form by carbon steel knife bar and blade, it is characterized in that: go up soldering carbide chip (2) at carbon steel knife bar (1), carbon steel knife bar (1) is that carbon steel is made or worn out lathe tool for roll calibre, the width of carbide chip (2) is 15-35mm, and the pass lathe tool is wide at width.
2, according to the described lathe tool for roll calibre of claim 1, it is characterized in that: carbon steel knife bar (1) and carbide chip (2) cooperation place roughness are more than 5.
3, lathe tool for roll calibre according to claim 1, the thickness that it is characterized in that said carbide chip (2) is 6mm or more than the 6mm, opening the 4-8 bar wide on the cutter groove deeply respectively is 2.5mm ditch (3), on knife bar, step (4) is arranged with carbide chip contacts side surfaces position, between carbon steel knife bar (1) is gone up carbide chip (2) be one in conjunction with the plane.
