Description

Technical Field

[0001] The utility model relates to the technical field of metal thin plate processing, in particular to an automatic thin plate cutting device. Background Art

[0002] Metal sheets usually refer to metal sheets with a thickness ranging from 0.2 mm to 4.0 mm. The production methods are mainly divided into hot rolling and cold rolling. They are important raw materials for metal products. In the production process, it is usually necessary to use a laser cutting machine to cut the thin plates first and cut them into plates of suitable specifications.

[0003] The existing laser cutting process of metal sheets has the following disadvantages: when using a laser cutting machine to cut metal sheets, due to the thin thickness of the sheet, the edge of the sheet is prone to warping during the cutting process, and the warped sheet is prone to hit the cutting head, causing a head collision problem, which affects the service life of the laser cutting head. For this reason, we propose an automated thin plate cutting device. Utility Model Content

[0004] The main purpose of the utility model is to provide an automated thin plate cutting device, which can effectively avoid damage to the cutting head caused by edge warping during thin plate cutting by installing a protective mechanism at the cutting end of a laser cutting machine, thereby effectively solving the problems in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] An automated thin plate cutting device comprises a laser cutting machine and a protective mechanism. The cutting end of the laser cutting machine is provided with the protective mechanism, and the protective mechanism comprises a cutting head, a mounting frame, a sleeve, a spring and a limit rod. The cutting end of the laser cutting machine is provided with a cutting head, and the outer periphery of the cutting head is sleeved with a mounting frame, the four corners of the mounting frame are fixedly connected with sleeves, and the inner part of the sleeve is vertically movably connected with the limit rod through a spring.

[0007] Furthermore, it also includes a mounting mechanism, and the bottom of the mounting frame is provided with a mounting mechanism, and the mounting mechanism includes a mounting hole, a clamping ring, a screw groove and a nut. The mounting frame is provided with a mounting hole at the center position inside the mounting frame and is inserted into the outer periphery of the cutting head, and a clamping ring is provided at the bottom of the mounting frame. The outer periphery of the clamping ring is provided with a screw groove and a nut is movably connected through the screw groove. When installing the protective component, the mounting hole inside the mounting frame is inserted into the outer periphery of the cutting head. After insertion, the clamping ring is fitted to the outer periphery of the cutting head, and the nut is tightened along the screw groove structure on the outer periphery of the clamping ring. During the process of screwing the nut in, the clamping ring is squeezed and the spacing between the through grooves is compressed, so that the clamping ring is tightly attached to the outer periphery of the cutting head, thereby fixing the position of the mounting frame and the protective component, and the installation and disassembly are convenient.

[0008] Furthermore, an insertion cavity is opened in the vertical direction inside the sleeve and the limiting rod passes through the insertion cavity, and the spring is installed inside the insertion cavity; the insertion cavity structure can limit the limiting rod so that it can only move in the vertical direction.

[0009] Furthermore, a rotating shaft is installed at the bottom end of the limiting rod and is movably connected to a caster through the rotating shaft; the rotating shaft and the caster cooperate to enable the limiting rod to move smoothly during the movement of the cutting head.

[0010] Furthermore, through grooves are provided between the clamping rings in the vertical direction; the through groove structure allows a spacing between the clamping rings, thereby facilitating the clamping rings to be clamped on the outer periphery of the cutting head when the nut is screwed in.

[0011] Compared with the prior art, the utility model has the following beneficial effects: the cutting end of the laser cutting machine cuts the metal sheet through the cutting head, and before the cutting operation, a mounting bracket is installed on the outer periphery of the cutting head and its position is fixed. After the mounting bracket is installed in place, ensure that the end of the limit rod is lower than the bottom position of the cutting head. When the cutting operation is performed, the cutting head moves down so that the end of the limit rod contacts the thin plate, and then the cutting head continues to move down to the cutting position, and the limit rod moves up without affecting the normal operation of the cutting head. When the cutting edge of the thin plate warps, its warped position will push the corresponding position upward The limit rod is supported by the spring elastic force to maintain downward pressure, which can limit the warping of the thin plate, thereby avoiding the head collision caused by warping and protecting the normal use of the cutting head; when installing the protective component, the mounting hole inside the mounting frame is inserted into the outer periphery of the cutting head. After insertion, the clamping ring fits the outer periphery of the cutting head, and the nut is tightened along the screw groove structure on the outer periphery of the clamping ring. During the process of screwing the nut in, the clamping ring is squeezed and the spacing between the through grooves is compressed, so that the clamping ring is closely attached to the outer periphery of the cutting head, thereby fixing the position of the mounting frame and the protective component, and the installation and disassembly are convenient.
