Description

Technical Field

[0001] The present application relates to the field of cutting machines, and in particular to an automatic feed mechanism for cutting machines. Background Art

[0002] In the prior art, when manufacturers need to cut a large coil into several sections, they often use cutting machines to perform the cutting process.

[0003] Among them, common cutting processing machines mainly include a frame, on which is installed a mounting mechanism for mounting a coil, and on which is installed a driving mechanism for driving the coil to rotate. When the coil is mounted on the mounting mechanism, the driving mechanism drives the coil to rotate; the frame is also equipped with a tool base, which is located on one side of the coil. The tool base can be adjusted on the frame, and a tool bracket is slidably mounted on the tool base. The tool is rotatably mounted on the tool frame, and a handwheel mechanism for driving the tool bracket toward or away from the coil is installed on the tool base.

[0004] During the process of cutting the coil, the user first adjusts the position of the tool holder according to the required length of the coil, and then drives the tool holder toward the coil through the handwheel mechanism. At the same time, the coil rotates at high speed, so that the tool completes the action of cutting the coil; when the coil is cut, the user drives the tool holder toward the coil away from the coil through the handwheel mechanism to separate the tool and the coil.

[0005] However, manually controlling the cutting tool to advance and retract to complete the cutting of the coil is time-consuming and labor-intensive, and it is difficult to accurately control the depth of the cutting. There is room for improvement. Utility Model Content
