Abstract
The utility model discloses a drill hole die for a flange bolt hole, belonging to the flange drilling technique, and mainly solving the problems that in the prior art, the drilling position is inaccurate and the drilling efficiency is low. The drill hole die for the flange bolt hole comprises a drill die body provided with a through hole passing through the upper surface and the lower surface thereof. A drill sleeve is arranged in the through hole. A locating boss matched with an inner hole of the flange is arranged on the center of the lower surface of the drill die. The drill die has a hollow disk structure with the thickness ranging from 10 mm to 40 mm. The locating boss is a multi-step trapezoidal boss and is 4 mm to 10 mm high. A drill sleeve is made of medium carbon steel. The drill hole die can accurately locate the drill hole, ensure the quality of the drill hole, greatly improve the drilling efficiency and realize mass production for the flange drill hole.
Description
Technical field
The utility model relates to a kind of boring mould, specifically, relate to a kind of on flange the boring mould of auger shell keyhole.
Background technology
Pipeline, pipeline adpting flange use very general in every profession and trade, the conventional method of auger shell keyhole is the line bore process on flange, promptly be on flange, to need to bore the line earlier of empty position,, bore empty instrument in use then and bore empty in scribing position with spotting.There are a lot of defectives in the empty technology of this traditional brill: not only efficient is extremely low, and bore position can not guarantee that accurately quality also is difficult to assurance, and can not satisfy the needs of batch process, and workman's technical merit is also had relative higher requirement with qualification.Along with oil industry rapid development in recent years, high strength, high leakproofness, bear high pressure steel flanges use more and more widely, traditional line is bored empty technology and can not be met the need of market, and the flange production industry is badly in need of a kind of empty technology of brill that can satisfy the present stage Technology Need.
The utility model content
The utility model relates to a kind of flange bolt hole drill punch die, solves problems of the prior art, guaranteeing the accurate heart of boring and boring under the prerequisite of empty quality, improves drilling efficiency, realizes that flange bores empty batch process.
To achieve these goals, the technical solution adopted in the utility model is as follows:
Flange bolt hole drill punch die comprises model drilling body, and described model drilling body is provided with the through hole that runs through its upper and lower surface, is provided with drill bushing in through hole, is provided with the positioning boss that matches with the flange endoporus at the model drilling body lower surface.
Described model drilling body is the inner disk that is provided with hollow cavity.
The thickness of described model drilling body is 10～40mm.
Described positioning boss is arranged at the lower surface center of model drilling body.
Described positioning boss is multistage stairstepping boss.
The height of described positioning boss is 4-10mm.
Described drill bushing is that medium carbon steel is made.
Principle of the present utility model is: utilize the positioning boss on the model drilling body to be connected with flange, model drilling body and flange are fixed in one, with the position alignment that needs on through hole on the model drilling body and the flange to hole, boring bar tool passes through hole and finish boring on flange then.Boring bar tool pass by after because the position-limiting action of the inner drill bushing of through hole, boring bar tool can only move forward and backward in boring procedure and can not double swerve, therefore can realize accurate location fully, drilling quality is effectively guaranteed.
The utility model not only can be realized the accurate location of holing, and improves drilling quality, can also realize the industrial mass boring of flange, and drilling efficiency is improved greatly, is a kind of flange drilling mould with very high practical value.
Description of drawings
Fig. 1 is a schematic cross-section of the present utility model.
The specific embodiment
As shown in Figure 1, flange bolt hole drill punch die comprises model drilling body 1, and described model drilling body 1 is provided with the through hole 2 that runs through its upper and lower surface, is provided with drill bushing 3 in through hole 2, is provided with the positioning boss 4 that matches with the flange endoporus at model drilling body 1 lower surface center.
Described model drilling body 1 is the inner disk that is provided with hollow cavity.
The thickness of described model drilling body 1 is 10～40mm.
Described positioning boss 4 is multistage stairstepping boss.
The height of described positioning boss 4 is 4-10mm.
Described drill bushing 3 is made for medium carbon steel.
Flange drilling process: earlier positioning boss 4 is connected with the flange endoporus, again with the position alignment that needs on through hole on the model drilling body 12 and the flange to hole, make model drilling body 1 be fitted in flange one end, with pull bar and pressing plate flange is firmly fixed on the platen, boring bar tool passes the through hole processing of can holing.When using radial drill, can easily drill bit be positioned in the drill bushing, thereby improve productivity ratio widely.
The utility model can be on equipment such as radial drilling machine, boring machine, milling machine just usefulness, have the scope of application widely.
