Description

Technical Field

[0001] The present invention relates to the technical field of flat punching and drilling, and particularly to a numerically controlled hydraulic flat high-speed punching and drilling compound machine. Background Art

[0002] In modern industrial production, machining technologies are constantly developing and progressing. With the increasing requirements of the manufacturing industry for the machining accuracy, efficiency, and versatility of parts, traditional single-function processing equipment has been difficult to meet complex production needs. For sheet metal processing, punching and drilling are common processing operations. In the past, punching presses and drilling machines were usually separate equipment, performing punching and drilling operations respectively.

[0003] The patent application with the application number CN201520478222.4 discloses a numerically controlled hydraulic flat high-speed punching and drilling compound machine, including: a bed body, a workbench arranged on the bed body, a hydraulic punching unit vertically installed on the bed body and located above the workbench, a spindle box vertically slidably installed on the bed body through a guide rail and located above the workbench, a power device for driving the spindle box to move up and down, a spindle vertically rotatably installed in the spindle box, a tool holder installed below the spindle, and a tool bar installed below the tool holder. The spindle is in transmission connection with a driving motor. Place the sheet material to be processed with holes on the workbench. For thin sheets, punching processing can be carried out through the hydraulic punching unit. For thick sheets, the driving motor drives the spindle to drive the tool holder to rotate, so that the tool bar rotates to realize drilling. During drilling, the power device drives the spindle box to move down, so that the drilling depth can be controlled, thus realizing convenient selection of punching processing or drilling processing for the sheet material according to different thicknesses, and improving the processing efficiency.

[0004] When existing equipment is in use, most of them simply combine a drilling machine and a punching machine together, which results in two sets of calculation methods for the processing positions of the sheet material by the equipment, one for detecting the drilling position and the other for detecting the punching position. This makes the calculation of the equipment too complex, prone to errors and failures, and is not conducive to the processing of the sheet material by the equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide a numerically controlled hydraulic flat high-speed punching and drilling compound machine to solve the problems raised in the above background art.

[0006] To solve the above technical problems, the present invention provides the following technical solution: A numerically controlled hydraulic flat high-speed punching and drilling compound machine, including a first base, a workbench is fixedly connected to the top of the first base, and a first horizontal moving device is fixedly connected to the outer wall of the first base.

[0019] 4. By providing a movable component, when the device needs to switch the processing structure, the movable component moves outward.
