The existing cutter for pipeline tapping is extremely easy to wear, needs to be frequently replaced, is not easy to remove chips, influences the cutting process, and is high in use cost, low in efficiency and high in safety risk.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a novel pipeline tapping cutter to solve the problem that current cutter needs often to be changed, use cost is high, inefficiency.
The utility model discloses a realize like this: a pipeline tapping cutter structurally comprises a cutter body and a blade, wherein the cutter body comprises a cutter tail, a cutter rod and a cutter head which are integrated, the cutter head comprises a first mounting head and a second mounting head which are symmetrical, a first mounting surface is arranged on the inner side surface of the first mounting head, a second mounting surface is arranged on the inner side surface of the second mounting head, the first mounting surface and the second mounting surface are parallel to each other and parallel to the axis direction of the cutter body, and the blade is detachably mounted on the first mounting surface and the second mounting surface.
The middle parts of the first mounting head and the second mounting head protrude out of two sides.
The blade edge of the blade protrudes out of the first mounting head and the second mounting head.
The cutter body is provided with two symmetrical chip grooves, the two chip grooves are respectively close to the first mounting surface and the second mounting surface, and the length directions of the chip grooves are the axial direction of the cutter body.
The cutter body is formed by one-step processing.
The first mounting surface and the second mounting surface are respectively provided with a bolt hole, and the blade is mounted on the cutter head through bolts.
The utility model discloses a pipeline trompil instrument blade adopts removable formula tool bit, and when blade wearing and tearing are serious directly change the blade can. The cutter tail, the cutter rod and the cutter head of the cutter are integrated, the rigidity and the strength of the cutter body are high, the cutter body is formed by one-step machining, the coaxiality and the straightness of the cutter are good, the abrasion of a hole forming tool can be reduced, and the cutter can be used for high-speed cutting and low-speed intermittent cutting. Two blades arranged on the cutter are symmetrically and uniformly stressed, so that the stability of machining holes is improved, and the straightness of pipeline hole opening is ensured. The scrap iron generated by cutting during machining is fine scraps, and can be discharged through the scrap discharge groove, so that the cutting resistance during cutting is reduced, the machining of the hole in the pipeline is completed at one time, and the machining time is shortened.

Fig. 1 is a schematic structural diagram of the present invention.
Fig. 2 is a schematic structural view of the knife body of the present invention.
Fig. 3 is a view of the cutter body of the utility model viewed from the cutter head to the cutter bar.
In the figure: 1. a cutter body; 2. a blade; 11. a cutter tail; 12. a cutter bar; 13. a cutter head; 14. a chip groove; 131. a first mounting head; 132. a second mounting head; 133. a first mounting surface; 134. a second mounting surface.
Detailed Description
As shown in fig. 1, fig. 2 and fig. 3, the utility model discloses a cutter body and blade, the cutter body includes integrative sword tail, cutter arbor and tool bit. The cutter head comprises a first mounting head and a second mounting head which are symmetrical, a first mounting surface is arranged on the inner side surface of the first mounting head, a second mounting surface is arranged on the inner side surface of the second mounting head, the first mounting surface and the second mounting surface are parallel to each other and parallel to the axis direction of the cutter body, and the blade is detachably mounted on the first mounting surface and the second mounting surface.
The middle parts of the first mounting head and the second mounting head protrude out of two sides, and the first mounting head and the second mounting head are respectively composed of three inclined planes which form a tip positioned in the middle. The first mounting surface and the second mounting surface at the inner sides of the first mounting head and the second mounting head are respectively provided with a blade, the cutting edge of the blade protrudes out of the first mounting head and the second mounting head, and the tip of the blade can be firstly contacted with the pipe wall to be processed to start hole forming processing when in use.
Two symmetrical chip removal grooves are formed in the cutter body, the two chip removal grooves are respectively close to the first installation surface and the second installation surface, and the length direction of each chip removal groove is the axial direction of the cutter body. The chip groove is arranged close to the blade, when the blade cuts pipeline materials to form iron chips, the iron chips enter the chip groove and are discharged through the chip groove, and therefore the influence of the iron chips generated during drilling processing on the processing is avoided.
The cutter body is one-time forming, and the cutter body has better intensity and toughness after the thermal treatment, can bear the stress of the change of the trompil in-process because the interrupted cutting produces, has improved the life of cutter body.
The first mounting surface and the second mounting surface are respectively provided with a bolt hole, and the blade is mounted on the cutter head through the bolt. The insert is replaceable and, when the insert cannot be used further due to cutting wear, the insert is removed directly from the mounting head, replaced with a new insert and screwed down by means of the bolt.
The utility model discloses a pipeline trompil instrument blade adopts removable formula tool bit, and when blade wearing and tearing are serious directly change the blade can. The cutter tail, the cutter rod and the cutter head of the cutter are integrated, the rigidity and the strength of the cutter body are high, the cutter body is formed by one-step machining, the coaxiality and the straightness of the cutter are good, the abrasion of a hole forming tool can be reduced, and the cutter can be used for high-speed cutting and low-speed intermittent cutting. Two blades arranged on the cutter are symmetrically and uniformly stressed, so that the stability of machining holes is improved, and the straightness of pipeline hole opening is ensured. The scrap iron generated by cutting during machining is fine scraps, and can be discharged through the scrap discharge groove, so that the cutting resistance during cutting is reduced, the machining of the hole in the pipeline is completed at one time, and the machining time is shortened.
