Abstract
The utility model relates to a welded multitooth annular drill with inside chip removal, which is one kind of annular drills which are also named as trepanning tools, and aims at resolving the problems of complex structure, poor manufacturability, difficult processing and high cost caused by too low utilization rate of raw materials of the existing integrated annular drill. The welded multitooth annular drill with inside chip removal is composed of a tool bit and a drill rod which are integrated in butt welding mode through friction welding, wherein the tool bit is made of large-diameter material; the drill rod is made of small-diameter material and designed into a standard part accordingly to using equipment; and the tool bit can be cut off when scrapped while the drill rod can be used continuously. The welded multitooth annular drill with inside chip removal is installed on a drilling machine to be used for nesting drilling, and mostly used for drilling large-diameter holes above phi 30mm.
Description
Technical field
The utility model relates to annular drill, specifically is the multiple tooth interior chip removal annular drill of a kind of welded type.
Background technology
Annular drill also claims trepanning tool, and the annular drill that uses at present all is that cutter head and drilling rod are unitary whole formula structure, generally with bearing steel or thick-walled seamless steel pipes manufacturing, also useful bar processing.Its shortcoming is: 1. complex structure, and difficulty of processing is big, and manufacturability is poor; 2. the raw material scrap rate is big, and stock utilization is low, thereby the manufacturing cost height; 3. after cutter head used a period of time, because of wearing and tearing are scrapped, whole annular drill must be scrapped, and waste is big, and is very uneconomical.So it is many that structure lacks filling, need to improve.
Summary of the invention
The utility model provides a kind of welded type multiple tooth interior chip removal annular drill at the shortcoming that now exists with chip removal annular drill in multiple tooth, forms by new structure, improve processing technology, reduce material consumption, enlarge waste and old product utilization, thereby the reduction manufacturing cost is increased economic efficiency.
The technical solution of the utility model is as follows: welded type multiple tooth in the chip removal annular distance be drilled with cutter head and drilling rod two parts, described cutter head is a body of tool bit, drilling rod is the drilling rod body, is two individual part, the two with friction welding to being welded into the integral loop hole drill.
Compare with existing annular drill, the beneficial effects of the utility model are as follows: 1. body of tool bit and drilling rod body are two parts, and processing greatly reduces difficulty of processing respectively, has improved processing performance, save man-hour, have reduced manufacturing cost significantly; 2. two parts blanking respectively, the body of tool bit diameter is big, uses the major diameter material, and drilling rod body diameter is little, use the minor diameter material, and used a major diameter material originally, after making respectively, both reduce the machining amount, saved a large amount of major diameter raw material again, further reduced manufacturing cost; 3. the annular drill scrapped of wearing and tearing, generally be that body of tool bit is scrapped, drilling rod is still intact, and when renewing, the cutter head that will give up is clipped, only need to make new cutter head, with the welding of new cutter head and former drilling rod body new annular drill, saved the raw material and the machining period of a drilling rod, accomplish the waste product utilization, and can repeatedly utilize, economic benefit is particularly remarkable.

The drawing explanation
Among Fig. 1: 1-drilling rod body 2-body of tool bit 3-weld seam
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model, as shown in Figure 1, the chip removal annular drill was made up of body of tool bit 2 and drilling rod body 1 two parts in welded type was multiple tooth, the two uses the friction welding butt welding, form weld seam 3, weld seam 3 is linked to be an integral body with body of tool bit 2 and drilling rod body 1, is the finished product annular drill after machining.The version of body of tool bit 2 and drilling rod body 1 adopts the version of existing cutter head and drilling rod.Add man-hour, No. 45 carbon constructional quality steels of body of tool bit 2 usefulness major diameters are manufactured, No. 45 carbon constructional quality steels of drilling rod body 1 usefulness minor diameter are manufactured, and the also available thick-walled seamless steel pipes of body of tool bit 2 is manufactured, and drilling rod body 1 can substitute with the drilling rod body that the annular drill of scrapping is clipped behind the cutter head.The scrapping of annular drill mostly is the body of tool bit wearing and tearing, and the drilling rod body is typically designed to standard universal spare, useless body of tool bit is clipped, the new cutter head of on former drilling rod body, burn-oning new annular drill.The drilling rod body can be repeatedly used like this, has both economized the machining period of drilling rod body, has avoided the waste of high-quality steel again.
Claims (2)
- A welded type multiple tooth in the chip removal annular drill, comprise cutter head and drilling rod two parts, it is characterized in that described cutter head is body of tool bit (2), drilling rod is drilling rod body (1), the two is two individual part, with friction welding to being welded into the integral loop hole drill.
- 2. annular drill according to claim 1 is characterized in that the available thick-walled seamless steel pipes of body of tool bit (2) manufactures.
