Description

Technical Field

[0001] This utility model relates to the field of laser cutting technology, and in particular to a laser cutting machine. Background Technology

[0002] Laser cutting machines are commonly used for cutting long tubes, profiles and other workpieces. When the existing equipment cuts to the end of the tube, most of the tube's length is inside the front clamping assembly, and the laser cutting head cannot cut it, resulting in an excessively long tail of the tube and a lot of material waste. Utility Model Content

[0003] The main purpose of this invention is to propose a laser cutting machine that aims to solve the technical problem of excessively long residual material in the prior art, resulting in significant material waste.

[0004] To achieve the above objectives, this utility model proposes a laser cutting machine, including a frame. The frame is equipped with a cutting assembly, a front clamping assembly, a rear clamping assembly, and a first clamping assembly. The front clamping assembly is located in front of the rear clamping assembly, and the first clamping assembly is located in front of the front clamping assembly. The cutting assembly is located behind the first clamping assembly. The frame is also equipped with a rear clamping movement drive device and a front clamping movement drive device. The rear clamping movement drive device is convectively connected to the rear clamping assembly and can drive the rear clamping assembly to move in a front-to-back direction. The front clamping movement drive device is convectively connected to the front clamping assembly and can drive the front clamping assembly to move between the front and rear sides of the cutting assembly.

[0005] The workpiece to be cut is fed from the rear and passes through the rear clamping assembly. The rear clamping assembly clamps the workpiece and, driven by the rear clamping movement drive, pushes it forward from the rear. The workpiece moves to the underside of the cutting assembly for cutting. The workpiece can pass through the front clamping assembly, which supports it. The front clamping movement drive can move the front clamping assembly between the front and rear sides of the cutting assembly. When the front clamping assembly is behind the cutting assembly, the cutting assembly cuts the workpiece extending from the front of the front clamping assembly; when the front clamping assembly moves to the front of the cutting assembly, the cutting assembly cuts the workpiece located behind the front clamping assembly. When the tail of the workpiece is cut, the front of the workpiece can be moved to the first clamping assembly, and the front clamping assembly moves to the front of the cutting assembly. The cutting assembly cuts off the tail end of the workpiece, and then the first clamping assembly clamps the remaining last section of the workpiece. Next, the front clamping assembly moves to the rear of the cutting assembly, leaving the remaining workpiece completely in front of the front clamping assembly. The first clamping assembly can then release the workpiece, allowing it to fall. In this invention, the front clamping assembly can move between the front and rear sides of the cutting assembly, and the first clamping assembly can clamp the last piece of workpiece to cut off the tail end of the workpiece, reduce the tail length, reduce material waste, and make it easier for the last piece of workpiece to fall off.

[0006] Preferably, the laser cutting machine further includes a feeding ramp, which is fixed to the front side of the front clamping assembly, and the first clamping assembly is disposed above the feeding ramp.

[0007] The unloading ramp can move back and forth with the front clamping assembly without affecting its movement. Workpieces cut off from the front of the front clamping assembly, as well as the last section of workpiece released by the first clamping assembly, fall onto the unloading ramp and slide down it, facilitating workpiece unloading.

[0008] Preferably, the frame is provided with a rear discharge chute, which is located behind the front clamping assembly. Workpieces falling from the rear of the front clamping assembly can fall into the rear discharge chute for unloading.

[0010] The first cylinder can drive the front clamping assembly to move back and forth. A first baffle is set on the rear side of the front clamping assembly. The first baffle moves back and forth with the front clamping assembly and is set on the upper side of the first cylinder. In this way, the first baffle can block the workpiece falling from the rear side of the front clamping assembly to prevent it from damaging the first cylinder.

[0011] Preferably, the cutting assembly includes a cutting base, which is fixedly connected to the frame. The cutting base is provided with a left-right cutting drive device and a left-right cutting slide block. The left-right cutting drive device is convexly connected to the left-right cutting slide block and can drive the left-right cutting slide block to slide in the left-right direction. The left-right cutting slide block is provided with a right-left-right cutting drive device and a right-right cutting slide block. The right-left-right cutting drive device is convexly connected to the right-right cutting slide block and can drive the right-right cutting slide block to slide in the up-down direction. The right-right cutting slide block is provided with a laser cutting head.

[0012] The left and right cutting drive device can drive the laser cutting head to move in the left and right direction, and the up and down cutting drive device can drive the laser cutting head to move up and down. With the help of the rear clamping assembly to push the workpiece back and forth, different shapes and sizes of cuts can be made on the workpiece.

[0013] Preferably, the cutting base is a gantry frame spanning the left and right directions, the front clamping assembly can pass through the lower side of the cutting base, the cutting base includes a crossbeam located on the upper side, and the left and right cutting drive device is disposed on the crossbeam.

[0015] The front clamp rotary drive motor is positioned upwards to reduce the amount of waste material falling onto it during cutting. The front clamp rotary drive motor and the laser cutting head are offset to the left and right, so the laser cutting head does not need to be raised above the front clamp rotary drive motor when the front clamp assembly is in motion, thus reducing the lifting height of the laser cutting head.

[0016] Preferably, the upper and lower sliding blocks for cutting are further provided with a cutting rotation drive device, which is connected to the laser cutting head for transmission. The cutting rotation drive device can drive the laser cutting head to rotate and tilt.
