Variable multi-hole perforating device and perforating method thereof

Abstract

The invention discloses a variable multi-hole perforating device and a perforating method thereof. The variable multi-hole perforating device comprises drills, a drilling plate and drill bushings. Thedrilling plate penetrates the drills to be fixed outside the drills, and the drill bushings are arranged outside the drills. Each drill comprises a first drill, a second drill and a drill middle portion, wherein the first drill and the second drill are arranged at two ends of the middle of the drill, the first drill is a straight drill, the second drill is a segmental drill and comprises a secondscrew groove and a third screw groove, and the diameter of the second screw groove of the second drill is larger than that of the third screw groove. The variable multi-hole perforating device and the perforating method thereof have advantages that by improvement of the perforating device, more drill holes can be used at the same time, and accordingly production efficiency of drill rigs is improved, time consumption is reduced, and drill rig production cost is reduced while drill performances are improved; in addition, simplicity and convenience in operation are achieved, and abrasion of drill rig components is reduced.

Description

technical field [0001] The invention relates to the technical field of drilling, in particular to a variable multi-drilling drilling device and a drilling method thereof. Background technique [0002] With the development of social production and manufacturing industry, punching device and punching technology are also required to be improved. With the development of the manufacturing industry, how to improve production efficiency has become the subject of many people's research. As one of the common industrial technologies in manufacturing --- punching technology, how to optimize the punching technology to reduce production costs and improve work efficiency deserves the attention of many people. [0003] There are many types of drilling drills, which can be divided into: twist drills, flat drills from the appearance, deep hole drills, reaming drills, etc. from the function, and can be divided into: high-speed steel drills, hard Alloy drill bits, tungsten steel drill bits, ...

AI Technical Summary

Problems solved by technology

Different drill bits can drill holes with different apertures and different laces. However, there are many types, and there are more options for replacing drill bits. The time for replacing drill bits in drilling is also longer, which is not conducive to people's production and life.

[0004] The common drilling devices on the market are basically a drill hole. The traditional drilling device and drilling technology are simple, and one drilling machine can only use one drill bit, which makes the production efficiency not high. When the drilling pattern is different, the drilling machine with one drill bit needs to spend more time to drill the hole, and it will also waste a lot of time when finding the axis of the hole in the pattern. In addition, when the traditional drilling machine drills holes with different diameters, it often It is very inconvenient to replace the drill bit and then find the central axis of the previous drilling, and frequent replacement of the needle will also cause wear to the drill and reduce the service life of the drill
