[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0017] PFA tube cutting device, such as Figures 1 to 4 As shown, it includes a workbench 1, a controller 19 is provided on one side of the workbench 1, a clamping mechanism for clamping the round tube to be cut is installed on the workbench 1, the clamping mechanism is slidably connected to the slide rail 10 on the workbench 1, one side of the clamping mechanism is threadedly connected to the screw rod 6, one end of the screw rod 6 is connected to the driving mechanism 7, and the other side of the clamping mechanism is slidably connected to the guide rod 9. A cutter disc 13 is also installed on the workbench 1, and a tool 16 is installed on one end of the cutter disc 13 arranged toward the clamping mechanism. The cutter disc 13 is connected to the motor 15 through a transmission mechanism 14, thereby driving the cutter disc 13 to drive the tool 16 to rotate.
[0018] In this embodiment, the transmission mechanism is a conventional structure, which is mainly used to transmit the rotation of the motor shaft to the rotation of the cutter disc, and can adopt a gear structure, a belt structure, etc.
[0019] The controlled end of the motor 15 is connected to the output end of the controller 19, and the controller controls the motor to drive the cutter head to rotate to complete the cutting of the round pipe.
[0020] The clamping mechanism includes a bracket 5 that is slidably assembled with the slide rail 10, and a lower clamping seat 2 and an upper clamping seat 3 are installed on the bracket 5. A circular hole structure for installing a clamp 4 is formed between the upper clamping seat 3 and the lower clamping seat 2, and the clamp 4 is used to clamp the round tube to be cut.
[0021] The upper clamping seat 3 and the lower clamping seat 2 are locked and connected by locking bolts on both sides.
[0022] A limiting bolt is provided on the slide rail 10 , and the slide rail 10 and the workbench 1 are locked by the limiting bolt. At the same time, the limiting bolt can also limit the movement of the clamping mechanism.
[0023] The driving mechanism includes a driving box, one end of the screw rod 6 is extended into the driving box, and a second bevel gear 12 is provided at one end of the screw rod 6 extending into the driving box. The second bevel gear 12 is meshed with the first bevel gear 11 in the driving box for transmission. The first bevel gear is connected to the roller turntable 8 provided on the top of the driving box through a connecting shaft. By rotating the roller turntable 8, the screw rod is driven to rotate under the transmission action of the first bevel gear and the second bevel gear, and then the rotational motion of the screw rod is converted into linear motion of the bracket. The bracket carries the round tube to be cut close to the tool to complete the cutting.
[0024] A waste material discharge port 17 is provided on the workbench 1 below the cutter 16 , an inclined discharge chute is provided below the waste material discharge port 17 , and a waste material box 18 is provided below the discharge chute on one side of the workbench 1 for receiving the cut waste.
[0025] A guide rail 20 is further provided on the workbench 1 located in front of the cutter disc 13 . A ruler is provided on one side of the guide rail 20 . A ruler limiting plate 21 is slidably provided on the guide rail 20 for setting the length of the round tube to be cut.
[0026] The scale limiting plate 21 is further provided with a scale fixing handle 22 for fixing the scale limiting plate 21 .
[0027] The operating process of the present invention is as follows: First, select a tool with a suitable inclination angle according to the required cutting angle and install it on the cutter disc, place the round tube to be cut into the clamp 4, then place the clamp on the lower clamping seat 2, and then cover the upper clamping seat 3 on the lower clamping seat 2 to clamp the clamp 4, and clamp the upper clamping seat 3 and the lower clamping seat 2 with the locking bolt.
[0028] Afterwards, slide the ruler limit plate to the specified position of the ruler and lock it, so that the end of the round tube abuts the limit plate to determine the cutting length.
[0029] After installing the cutter and the round pipe to be cut, start the motor to make the cutter disc drive the cutter to rotate.
[0030] Next, the roller turntable 8 is rotated, and the screw is driven to rotate under the transmission action of the first bevel gear and the second bevel gear, and the rotational motion of the screw is converted into the linear motion of the bracket. The bracket moves the round tube to be cut close to the tool, and the angle cutting is completed by coordinating the rotation of the cutter disc and the forward feed of the pipeline using the shear force of the blade.
[0031] The inclination angle of the tool is prepared in advance. If other angles need to be cut on the pipe, the tool of the corresponding angle needs to be remade and replaced, and then the cutting is completed according to the above operations.
[0032] When the bracket moves to the limit bolt and contacts the limit bolt, the motor is controlled to stop moving, and then the roller turntable is rotated in the opposite direction to smoothly push the cut PFA tube out of the blade cutting area.
[0033] Finally, loosen the locking bolt, remove the upper clamping seat, and remove the clamp on the PFA tube. Gently pull the tube out of the clamp. The entire tube cutting operation is now completed.
[0034] The present invention provides a PFA tube cutting device with a simple structure and easy operation. A transmission mechanism is provided to connect the cutter disc and the motor, so that the tool can bevel the PFA tube. At the same time, a clamping mechanism is driven by a screw rod to clamp the pipeline and move it toward the tool, so that the pipeline is close to the tool and the cutting is completed during the rotation of the tool. In addition, guide rails and scale limit plates are provided on the workbench to cooperate in positioning the length of the pipeline to achieve the purpose of precise cutting.
