Problems solved by technology

[0005] The milling cutter will be cooled during the milling process. The traditional cooling method mainly adopts the pouring (external cooling) method. This method uses a large amount of cutting fluid to pour in the technical area to ensure the actual processing needs, but this method obviously leads to processing costs. and the effect is not good in special processing methods such as deep hole processing. The use of a large amount of cutting fluid is likely to cause environmental pollution and is harmful to the health of equipment operators.

Embodiment 1

[0031] Such as figure 1 As shown, a square shoulder milling cutter with a self-cooling and lubricating structure includes a connecting handle 01 and a cutter head body 02; the cutter head body 02 is provided with a plurality of spiral mounting parts 021; each spiral mounting part 021 is from the top Downward and along the helical direction, a plurality of blades 03 are arranged successively (the blades 03 are fixedly installed by screws 023); the cooling lubricant main channel 1 is arranged on the connection knife handle 01 and extends into the cutter head body 02; the cooling lubricant secondary flow There are multiple channels 2, and multiple cooling and lubricating fluid auxiliary flow channels 2 are arranged in each screw mounting part 021, and are adapted to the shape of the screw mounting part 021;

[0032] The top and bottom of each blade 03 are respectively provided with a rake face cooling lubricating liquid flow channel 21 and a flank cooling lubricating liquid flow ...

Embodiment 2

[0036] Such as figure 2 As shown, on the basis of Embodiment 1, the present invention has a further optimized design, that is, the square shoulder milling cutter is also provided with a cooling lubricant temporary storage area 3, and the cooling lubricant temporary storage area 3 includes The substrate 31 between the lubricant main channel 1 and the cooling lubricant secondary channel 2 is provided with a plurality of pores connected from its center to the entire outer surface (the diameter of the pores is less than the diameter of the cooling lubricant secondary channel). The cooling and lubricating fluid flows through the cooling and lubricating fluid main channel 1 to the cooling and lubricating fluid temporary storage area 3, so that the cooling and lubricating fluid can be temporarily stored in this position before the tool is ready to cut, and the cooling and lubricating fluid is cooled after the square shoulder milling cutter starts cutting Under the action of pressure...

Abstract

The invention particularly relates to a square shoulder milling cutter with a self-cooling lubricating structure. The square shoulder milling cutter comprises a connection cutter handle and a cutter bit body, the cutter bit body is provided with multiple spiral mounting parts, each spiral mounting part is sequentially provided with multiple blades in the spiral direction from top to bottom, a cooling lubricating liquid main flow way is arranged on the connection cutter handle and extends into the cutter bit body, multiple cooling lubricating liquid auxiliary flow ways are arranged in each spiral mounting part and are matched with the spiral mounting parts in a matched manner, and a front cutter face cooling lubricating liquid flow way and a rear cutter face cooling lubricating liquid flowway are arranged above and below each blade correspondingly. The cooling lubricating structure of the square shoulder milling cutter can cool cutting areas of the front cutter face and the rear cutterface of each blade, the cooling uniformity is good, and the cooling effect is obvious.

Description

technical field [0001] The invention relates to a machining tool, in particular to a square shoulder milling cutter with a self-cooling and lubricating structure. Background technique [0002] According to the processing type, the cutting process is mainly divided into: turning, drilling, milling, boring and grinding; [0003] Turning refers to the use of the rotary motion of the workpiece and the linear or curved motion of the tool to change the shape and size of the blank; drilling refers to the process of using the tool to process holes on the workpiece; The blade tool moves on the blank to cut the workpiece into the required shape and size; boring is a cutting process that uses a tool to enlarge a hole or other circular contours; grinding refers to the processing method of removing excess material on the workpiece with abrasives , which belongs to the finishing machining of mechanical processing; [0004] The main objects of general milling processing are: plane contou...
