Hardware processing is to process raw materials into various parts with lathes, milling machines, machine tools, and polishing machines according to customers' drawings or samples. Machine tools are common machines for hardware processing, also known as working machine tools or machine tools, habitually referred to as machine tools, generally divided into metal cutting machine tools, forging machine tools and woodworking machine tools. In modern machinery manufacturing, in addition to cutting, there are methods of processing mechanical parts such as casting, forging, welding, stamping and extrusion. In the use and production of the existing CNC machine tool punching device, the operator's hand does not leave the working area during punching, which is easy to cause Danger occurs when punching.

The technician provides a CNC machine tool for metal processing, which has the advantage of automatic power off when the hand does not leave the work area during stamping, which solves the problem that the operator's hand does not stop when stamping. Leaving the work area causes dangerous problems when punching. In order to achieve the above purpose, the numerical control machine tool adopts the following technical scheme: a numerical control machine tool for hardware processing, including a body, the upper surface of the body is provided with a gap, the top of the body is provided with a hydraulic rod, and one side of the hydraulic rod is provided A safe is fixedly connected, a sleeve and two sleeves are arranged in the safe, the one contact is electrically connected with the power line, and one end of the first sleeve is fixedly connected with a contact; the two sleeves are fixedly connected with the power socket The power socket is electrically connected with the two contacts; the bottom of the safe is provided with a mouth-shaped safety frame; the outer surface of the mouth-shaped safety frame is fixedly connected with a support rod, and the top of the support rod passes through the bottom surface of the safe and extends to the inside of the safe, a The outer surfaces of the casing and the second casing are fixedly connected with a limit ring, one side of the limit ring is fixedly connected with a strong spring, and the end of the strong spring away from the limit ring is fixedly connected with the inner side wall of the safe, so that by setting the strong spring and the limit Bit ring, so that the first and second contacts can always fit together during normal operation, ensuring CNC machine power supply stability

The inner bottom wall of the safe is fixedly connected with a sliding tube, and the sliding tube is arranged on the outer surface of the support rod. By arranging the sliding tube, the working stability of the support rod is improved, and the movement deviation of the support rod during the working process is avoided. The upper surface of the body is fixedly connected with a punching plate, and the upper surface of the punching plate is provided with a non-slip pattern, which can prevent the hydraulic rod from directly contacting the upper surface of the body during the punching process. Improve the use effect of stamping plates. The bottom surface of the body is fixedly connected with a decompression column, and the decompression column is located at the central support point of the body. It can withstand the main bearing pressure of the hydraulic rod on the body, and by setting the decompression column, the situation of insufficient bearing capacity of the body is avoided, and the overall stability of the CNC machine tool is improved. The outer surface of the hydraulic rod is provided with a chute, the upper surface of the mouth safety frame is fixedly connected with a balance rod, and the top of the balance rod is slidably connected with the chute. It will not move horizontally in the middle, which avoids the collision with the fuselage when the mouth safety frame is lowered, and improves the working effect of the mouth safety frame.

Compared with the prior art, the above CNC machine tool punches the workpiece through the operation of the hydraulic rod; when the worker's hand does not leave the top of the body in time, the The force pushes the mouth safety frame upward, the mouth safety frame pushes the support rod upward, the support rod pushes the insulating slider, the upward movement of the insulating slider separates the first contact and the second contact, thereby stopping the power supply operation to the hydraulic rod; In the CNC machine tool for hardware processing, by setting a strong spring and a limit ring, the first contact and the second contact can always be attached together during normal work, ensuring that < strong>The stability of the power supply of the CNC machine tool, the setting of the sliding tube avoids the movement deviation of the support rod during the working process, thereby improving the working stability of the support rod.
