Abstract
The improved thread connected stem consists of one stem body as the main part and one connecting piece with female threads welded or embedded to one end of the stem body. The connecting piece and the stem body are first machined separately and then assembled together. The present invention has high production efficiency, low production cost, long service and high product quality.
Description
Technical field
The invention belongs to the drill steel field, particularly a kind of improved prismatic or circle connect drill steel and extension bar drill steel soon.
Background technology
Drill steel cooperates with bore bit, is widely used in cutting into a mountain, field such as rock drilling, mining.Drill steel mainly is made up of the body of rod, and the body of rod generally is divided into the prismatic body of rod and two kinds of forms of the circular body of rod.In the use, drill steel cooperates with hammer drill, and the torsion of hammer drill is delivered to drill steel, and many drill steels link together by helicitic texture, forms to connect drill steel or extension bar drill steel soon, drives the bore bit work of end.Be the needs that guarantee to connect, the head end of drill steel and tail end are processed into required yin, yang helicitic texture respectively.The now used drill steel yin, yang helicitic texture and the body of rod are one, synchronous processing.Add man-hour because the external diameter of this end is greater than the body of rod, the method that needs at first the end to be forged with the heating pier makes it overstriking, makes required negative and positive threaded connector by machine again.In the process that the heating pier is forged, because the effect of hot-working stress, the drill steel quality is affected, and causes the initial failure of product.Working (machining) efficiency is low simultaneously, expense is high.
Summary of the invention
The object of the present invention is to provide a kind of split type improved screw connection drill rod.
The present invention is achieved in that
A kind of improved screw connection drill rod mainly is made up of the body of rod, it is characterized in that: install connector additional in the head end of the body of rod mode by welding or insert, establish negative thread in this connector end.
After the present invention adopted said structure, connector and body of rod split processing cooperatively interacted again, are solidly installed, and form split type connection drill steel.Easy to process, efficient is high, reduced cost of production simultaneously, has overcome the defective that forging stress produces, and is guaranteeing effectively to have improved the application life and the product quality of drill steel under the normal situation about using of drill steel.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention, and Fig. 2 is an another kind of structural representation of the present invention, and Fig. 3 is the third structural representation of the present invention, and Fig. 4 is the 4th a kind of structural representation of the present invention, and Fig. 5 is the 5th a kind of structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are elaborated.
In the accompanying drawing, 1 is that the body of rod, 2 is that pin thread connector, 3 is the female connection part.
Drill steel mainly is made up of the body of rod 1, and the body of rod 1 is divided into 1 two kinds of the prismatic body of rod 1 and the circular bodies of rod, and the prismatic body of rod 1 is based on six prismatics.For the circular body of rod 1, because its tail end external diameter is corresponding with the body of rod 1, the pin thread of its tail end adopts mach mode to make, and directly is processed into pin thread connector 2, and the external diameter of pin thread is corresponding with the body of rod 1, is convenient to being threaded of the body of rod 1.For the prismatic body of rod 1, the female connection part 3 of its head end is because its external diameter is greater than the body of rod 1, processing and fabricating is solidly fixed with the body of rod 1 more separately, and the internal diameter of its negative thread is corresponding with the body of rod 1, and can cooperate, thereby form being threaded of drill steel with the pin thread of the body of rod 1; The pin thread of the body of rod 1 tail end should be corresponding with the body of rod 1, so pin thread connector 2 also adopts independent processing and fabricating, is solidly fixed with the body of rod 1 again.
Shown in Figure 1, be the drill steel that the six prismatic bodies of rod 1 are formed, the tail end of the body of rod 1 adds a pin thread connector 2, and pin thread connector 2 is made separately, the mode and the body of rod 1 by friction welding weld together, and carry out positive spiral shell mosquito processing after 2 welding of pin thread connector again.The head end of the body of rod 1 adds a female connection part 3, and the female connection part is established negative thread in 3 ends, and the negative thread external diameter is corresponding with the body of rod 1; This female connection part 3 is made separately, and the mode and the body of rod 1 by friction welding weld together, and carry out the machine of negative thread again.
Shown in Figure 2, be the drill steel that the another kind of six prismatic bodies of rod 1 are formed, the tail end of the body of rod 1 also connects a pin thread connector 2 by friction welding.Adopt taper fit between the female connection part 3 of the body of rod 1 head end and the body of rod 1, the mode by hot charging or cold charge is installed in together.
Shown in Figure 3, be the drill steel that the third six prismatics body of rod 1 is formed, the tail end of the body of rod 1 connects a pin thread connector 2 by friction welding.Adopt the screw thread spinning to cooperate between the female connection part 3 of the body of rod 1 head end and the body of rod 1.
Shown in Figure 4, be the drill steel that the circular body of rod 1 is formed, the pin thread connector 2 of the body of rod 1 tail end adopts integral type processing with the body of rod 1, utilizes machining mode to be processed into required pin thread, and the pin thread diameter is corresponding with the body of rod 1.Female connection part 3 split productions of the body of rod 1 head end are connected with the body of rod 1 by the mode of tapering insert or the mode of friction welding.
During use, the pin thread connector 2 of previous drill steel cooperates with the female connection part 3 of a back drill steel, and spinning forms the drill steel connector of sufficient length together, is used with hammer drill.Avoided the heating pier to forge the defective that stress produces.
Shown in Figure 5, be the connected mode of another prismatic body of rod 1.Pin thread connector 2 split productions are welded on two ends of the prismatic body of rod 1 respectively by the mode of friction welding, and two ends form pin thread connector 2 respectively, and its pin thread diameter is corresponding with the body of rod 1.By branch sleeve two drill steels are linked together during use, establish the negative thread that cooperates with described pin thread connector 2 in the branch sleeve.
