The invention discloses a deep hole trepanning machining forming device for an alloy cast iron profile and an application method of the deep hole trepanning machining forming device. The deep hole trepanning machining forming device comprises a lathe bed, an oil tank, a workpiece, a tool bar, a drilling mechanism and a tool bit mechanism, wherein a controller used for conducting coordinated control on all components of the device is installed at one side of the surface of the lathe bed; the oil tank used for storing cutting fluid is installed at one side of the lathe bed; an oil pump station is installed at one side in the oil tank; two V-shaped tables are installed at the left end of the top of the lathe bed; the workpiece is borne by the tops of the V-shaped tables; the drilling mechanism used for controlling the tool bar to operate is installed at the right side of the top of the lathe bed; and the tool bit mechanism used for conducting drilling operation on the workpiece is installed at the tail end of the tool bar. Vibration cutting and trepanning drilling are combined, the cutting output is effectively reduced, green and energy-saving cutting is achieved, the system is compact in structure, simple in transmission, high in kinematic accuracy, convenient to operate, and stable and reliable in machining process.

Description

technical field [0001] The invention relates to the technical field of deep hole casing processing, in particular to an alloy cast iron profile deep hole casing processing forming device and a method for using the same. Background technique [0002] Deep hole processing is an important branch in the field of mechanical processing. Deep hole processing technology and application research and development process have emerged in the production of gun barrels. Among the 29 manufacturing industries in China, at least half of them have direct demand for deep hole processing technology and equipment. In mechanical manufacturing, hole processing can be divided into shallow hole processing and deep hole processing. Nesting processing is an important form of deep hole processing. The processing tools used are called nesting drills, also known as ring drills. It is to leave a solid "nucleus" round bar in the center of the hole, and the "nucleus" can be left for future reuse or for othe...

Problems solved by technology

[0003] The existing deep hole nesting processing has some shortcomings in the process of processing: 1. Whether the chips of deep hole drilling can be discharged normally and smoothly becomes the key to affecting the efficiency of deep hole drilling, and it is also the bottleneck restricting the development of deep hole drilling One, regular chips cannot be formed in the traditional deep hole nesting process, and long chips will flow into the tool holder from the chip discharge port of the drill bit, and it is easy to block the tool holder after being wound, causing the circuit of high-pressure cutting oil to be interrupted. If the processing cannot be stopped in time, the chips will block the entire cutter bar, and even the phenomenon of knife punching and oil injection will occur, which will affect the processing efficiency and pose a certain safety hazard.

2. The tool part of the traditional deep hole nesting processing is generally made of ordinary carbon steel. The machining time is long, the tool life is short, and the production cost is high, which is not conducive to improving the processing performance of the material.
