Abstract
The utility model discloses a round broach, and relates to a mechanical cutting tool. The utility model provides the round broach with a cooling groove which is capable of cooling the broach, cutting as well as lubricating in a better way during broaching and cutting progresses. The round broach is sequentially provided with a clamping part, a front guiding part, a cutting part and a rear guiding part from front to back, wherein cooling liquid flow guide slots are formed in the front guiding part and the cutting part; the cooling liquid flow guide slot in the cutting part forms branches; the oil outlet of the cooling liquid flow guide slot is formed in the middle of the cutting part, while the oil inlet is formed between the clamping part and the front guiding part; and the oil inlet of the cooling liquid flow guide slot is connected with an oil inlet pipe.
Description
Technical field
The utility model relates to a kind of machine cut cutter, especially relates to a kind of round broach.
Background technology
Round broach is used very extensive aborning, can once accomplish the processing of thick, smart hole, has very high production efficiency.In actual production, according to the difference of its application, desired broaching tool design and make many specifications normally, and require the design accuracy of round broach high.Round broach is applied to the fine finishining of tubulose section bar more, and the dimensional accuracy of round broach directly influences the machining accuracy of section bar.Usually, in process, need be from the outside working position be carried out the spray of cooling fluid, simultaneously the broaching tool operations for forming is lubricated.
Summary of the invention
It is a kind of in broaching tool and working angles that the purpose of the utility model is to provide, and it is lubricated with cutting to cool off broaching tool better, has the round broach of cooling bath.
The utility model is provided with clamping part, leading to part, cutting tip and back targeting part from front to back successively; In part and cutting tip, be provided with the cooling fluid guiding gutter leading; The cooling fluid guiding gutter that is located at cutting tip forms branch; The oil-out of cooling fluid guiding gutter is located in the middle of the cutting tip; The oil-in of cooling fluid guiding gutter is located at clamping part and leading between part, and the oil-in of said cooling fluid guiding gutter is connected with oil inlet pipe.
The numbers of branches of said cooling fluid guiding gutter confirms that according to the specification length of round broach the quantity of said branch can adopt 5.
The advantage of the utility model is:
1) cooling fluid directly imports in the middle of the round broach, and along with circulating of cooling fluid, the heat that round broach produces the at work liquid that is cooled is taken out of, reaches the quick cooling purpose of round broach.
2) cooling fluid flows out at cutting tip, can be lubricated to cutting tip well.
3) can not cause the round broach expanded by heating along with the heat of processing generation, high with the round broach machining accuracy of the utility model.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In Fig. 1, respectively be labeled as: 1 clamping part, 2 leading to part, 3 cutting tips, 4 afterwards targeting parts, 5 cooling fluid guiding gutters, 6 oil inlet pipes.
The specific embodiment
Below through embodiment and combine accompanying drawing that the utility model is described further.
As shown in Figure 1, the utility model embodiment is provided with clamping part 1, leading to part 2, cutting tip 3 and back targeting part 4 from front to back successively; In part 2 and cutting tip 3, be provided with cooling fluid guiding gutter 5 leading; The cooling fluid guiding gutter 5 that is located at cutting tip 3 forms branch; The oil-out of cooling fluid guiding gutter 5 is located in the middle of the cutting tip 3; The oil-in of cooling fluid guiding gutter is located at clamping part 1 and leading between part 2, and the oil-in of said cooling fluid guiding gutter is connected with oil inlet pipe.
The numbers of branches of said cooling fluid guiding gutter confirms that according to the specification length of round broach in the present embodiment, round broach offers 2 cooling fluid guiding gutters, and the numbers of branches of cooling fluid guiding gutter is 5.
Claims (2)
1. a round broach is characterized in that being provided with successively from front to back clamping part, leading to part, cutting tip and back targeting part; In part and cutting tip, be provided with the cooling fluid guiding gutter leading; The cooling fluid guiding gutter that is located at cutting tip forms branch; The oil-out of cooling fluid guiding gutter is located in the middle of the cutting tip; The oil-in of cooling fluid guiding gutter is located at clamping part and leading between part, and the oil-in of said cooling fluid guiding gutter is connected with oil inlet pipe.
