Embodiment 1

[0033] Example 1, such as figure 1 As shown, a multifunctional drill-scraping drill bit includes a drill body 1, a hexagon socket head screw 2, a forming scraper 3, and a liner 4.

[0034] The specific connection is as follows: the liner 4 is installed on the drill body 1, the forming scraper 3 is installed in the square hole on the drill body 1, and is tightened and fixed by the hexagon socket head cap screw 2.

[0035] The operation steps are as follows:

[0036] 1. Determine the hole and groove size of the header (pipe) to be processed, and select the corresponding forming scraper 3. Then install the liner 4 in the drill body 1 (the outer diameter of the liner 4 is designed to be tapered, and attention should be paid to the installation direction during installation. The bottom diameter of the liner 4 is larger than the upper diameter). Afterwards, the forming scraper 3 is installed, and is tightened and fixed by the hexagon socket head cap screw 2. That is: after comple...

Embodiment 2

[0038] Example 2, such as Figure 5 As shown, another multifunctional drill bit includes a drill body 1, a hexagon socket head cap screw 2, a plug 5, and a sleeve reamer 6.

[0039] The specific connection is as follows: the sleeve reamer 6 is installed on the drill body 1, and the plug 5 is installed in the square hole on the drill body 1, so that the synchronous rotation of the sleeve reamer 6 and the drill body 1 is restricted, and the plug 5 passes through the hexagon socket head screw. 2 Tighten and fix.

[0040] The operation steps are as follows:

[0041] 1. The initial installation operation is the same as the implementation of the first operation, the difference is that the sleeve reamer 6 is used instead of the liner 4, and the plug 5 is used instead of the forming scraper 3.

Embodiment 3

[0043] Example 3, such as Figure 8 As shown, a multifunctional drill bit includes a drill body 1, a hexagon socket head screw 2, a forming scraper 3, and a sleeve reamer 6;

[0044] The specific connection is as follows: the sleeve reamer 6 is installed on the drill body 1, so that the sleeve reamer 6 and the drill body 1 are limited to rotate synchronously; the forming scraper 3 is installed in the square hole on the drill body 1, and the forming scraper 3 is tightened and fixed by the hexagon socket head cap screw 2, and the forming scraper 3 is provided with an installation limit step.

[0045] The operation steps are as follows:

[0046] The initial installation operation is the same as the implementation of the first operation, the difference is: the sleeve reamer 6 is used instead of the liner 4 .

Abstract

The invention discloses a multifunctional scraping drill bit. The multifunctional scraping drill bit comprises a drill bit main body, an inner hexagonal screw, a forming scraper and a liner tube, wherein the liner tube is mounted on the drill bit main body and can rotate in the drill bit main body around the drill bit main body; the forming scraper is mounted in a square hole in the drill bit main body and is screwed and fixed by the inner hexagonal screw. Another multifunctional drill bit is characterized by comprising a drill bit main body, an inner hexagonal screw, a plug block and a sleeve reamer, wherein the sleeve reamer is mounted on the drill bit main body, so that the synchronous rotation of the sleeve reamer and the drill bit main body is limited; the plug block is mounted in a square hole in the drill bit main body and is screwed and fixed by the inner hexagonal screw. The multifunctional scraping drill bit has the advantages of low manufacturing cost, high production efficiency, convenience in operation and the like, a scraper row can be completely replaced with the multifunctional scraping drill bit in terms of a using function, and the manufacturing cost of products is reduced.

Description

technical field [0001] The invention relates to a multifunctional drill-scraping drill bit. Background technique [0002] At present, the production workshop usually uses a drill bit and a scraper row to process the holes and grooves of the boiler header (pipe) with the scraper. This kind of processing method, in the actual use process, the header (pipe) tube hole and groove processing efficiency is low, which is not conducive to large-scale use in the workshop. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a multifunctional drill-scraping drill bit, which is used to replace the traditional twist drill and scraper row (with scraper), and to process the groove of the boiler header (pipe) pipe hole. [0004] In order to achieve the above object, the technical solution of the present invention is to provide a multifunctional drill-scraping drill bit, which is characterized in that it includes a drill body, a hexa...
