Description

Technical Field

[0001] The invention relates to the technical field of metal parts processing, in particular to a high-efficiency cooling device for numerically controlled processed metal parts. Background Art

[0002] Metal parts processing refers to the use of various mechanical processing techniques to cut, form, weld and other processes on metal materials to produce metal parts that meet the specifications. These parts are widely used in industries such as automobiles, aviation, and machinery manufacturing. CNC metal parts processing is a method of using computer-controlled machine tools to process metals. In the process of CNC metal parts processing, cooling is very important because a large amount of cutting heat is generated between the tool and the workpiece during cutting. Cutting heat can bring many adverse effects, such as increasing tool wear and reducing the service life of the tool. Excessive temperature can also change the physical properties of the workpiece material, cause thermal deformation, and affect the processing accuracy.

[0003] In the prior art, a common cooling method during CNC machining of metal parts is to use cutting fluid, by installing a nozzle next to the machining tool, and using the nozzle to spray the coolant to the contact area between the tool and the workpiece for cooling. However, different tools have different lengths. When a longer tool is replaced, the outlet end of the nozzle will be facing the blade of the tool. When the coolant is sprayed subsequently, the coolant will be sprayed onto the blade, and then flow down along the blade to the contact area between the tool and the metal part. Some of the coolant will not directly act on the cutting area, which not only causes a waste of coolant and increases production costs, but also affects the cooling effect, thereby affecting the machining effect of metal parts.

[0004] Therefore, we propose a high-efficiency cooling device for CNC machined metal parts to solve the problems raised in the above background technology. Summary of the invention

Start the liquid pump 201, and pump the coolant to the liquid delivery pipe 203, the rotating hose 204, the connecting pipe 205 and the arc pipe 206 in sequence through the liquid pumping pipe 202, and then divert it to the two fixed pipes 207, the adjustment hose 208 and the liquid inlet pipe 209, and then enter the spherical tube 210 after the angle is adjusted, and finally spray the coolant to the contact area between the tool body 1 and the metal parts through the two nozzles 211 for cooling. At the same time, the forward and reverse motors 304 are started, driving the gear 305 and the annular gear 302 to rotate, and driving the arc tube 206 and the adjustment component 4 to rotate together, further driving the two nozzles 211 to rotate around the tool body 1. When the annular gear 302 rotates one hundred and eighty degrees, the output end of the forward and reverse motor 304 will rotate in the opposite direction, driving the annular gear 302 to rotate one hundred and eighty degrees in the opposite direction.
