The utility model discloses simple structure, respond well, economical and durable, high-efficient reliable, the using widely of suitable drilling deep hole.
Description
Technical Field
The utility model belongs to the technical field of the drilling device, a drill bit for processing deep hole is related to particularly.
Background
Drilling is a very common machining mode in the production process, and a drill bit is an important tool for drilling. High-temperature alloy materials are common in the drilling process, but the high-temperature alloy materials have a series of characteristics of high hardness, poor cutting performance and the like, which bring difficulty to the drilling process, especially in the drilling process of deep-hole parts (the deep-hole parts are shown in fig. 3). In the prior art, a deep hole is machined by adopting a common twist drill, the chip removal capability is poor, cooling liquid is difficult to enter the head of a cutting drill bit, high temperature is easy to generate, the drill bit is broken, and products are scrapped.
Disclosure of Invention
The utility model aims to overcome above-mentioned shortcoming and provide a simple structure, respond well, economical and durable, high-efficient reliable drill bit for processing deep hole.
The utility model discloses the purpose and solve its main technical problem and adopt following technical scheme to realize:
the utility model discloses a drill bit for processing deep hole, including drillstock, cutter body, drill point, be connected with the cutter body on the drillstock, the cutter body head is provided with the drill point, wherein: each edge of the drill point is provided with a plurality of grooves, and the direction of each groove is parallel to the tangential direction of the edge.
The drill bit for processing deep holes is characterized in that: the groove is a circular arc groove body.
The drill bit for processing deep holes is characterized in that: the grooves are uniformly distributed at the edge of each edge.
The drill bit for processing deep holes is characterized in that: the number of the grooves is three.
Compared with the prior art, the utility model obvious advantage and beneficial effect have. According to the technical scheme, in the drill bit for processing the deep hole, the cutting edge of each edge of the drill tip is uniformly provided with the plurality of grooves, the direction of each groove is parallel to the tangential direction of the cutting edge, the number of the grooves can be determined according to the size of the drill bit, and the grooves can conveniently remove chips, so that the cutting speed is higher, and the processing is easier and more efficient; the coolant enters the drill bit, and the drill bit is more durable, so that the tool cost is reduced. The drill bit is formed by modifying a common twist drill bit, and is economical and feasible. In a word, the utility model discloses simple structure, respond well, economical and durable, high-efficient reliable, be fit for the using widely of drilling deep hole.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a left side view of the present invention;
fig. 3 is a schematic structural diagram of a deep-hole part.
The labels in the figure are:
1. a groove; 2. drilling a tip; 3. a cutter body; 4. a drill shank; 5. a part; 6. a porous body.
Detailed Description
The embodiments, structures, features and effects of the drill for deep hole drilling according to the present invention will be described in detail below with reference to the accompanying drawings and preferred embodiments.
Referring to fig. 1 to 2, the utility model discloses a drill bit for processing deep hole, including drillstock 4, cutter body 3, drill point 2, be connected with cutter body 3 on the drillstock 4, the 3 heads of cutter body are provided with drill point 2, wherein: each edge of the drill point 2 is provided with a plurality of grooves 1, and the direction of each groove 1 is parallel to the tangential direction of the edge. The groove 1 is a circular arc groove body. The grooves 1 are uniformly arranged at the edge of each edge. The number of the grooves 1 is three.
When the spiral drill is used, three grooves 1 are machined in the cutting edge of each face of the head of the drill by a common spiral drill in a linear cutting method, the direction of each groove 1 is parallel to the tangential direction of the cutting edge, and then burrs used are removed on a grinding machine. When the hole body 6 of the part 5 is processed, the cooling liquid is sprayed out by aiming at the groove 1 of the drill bit, the cutter is withdrawn after every 5mm of cutter feeding, and the cutter is fed again after complete cooling. The utility model discloses simple structure, respond well, economical and durable, high-efficient reliable, the using widely of suitable drilling deep hole.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any form, and any simple modification, equivalent change and modification made by the technical spirit of the present invention to the above embodiments do not depart from the technical solution of the present invention.
