[0021] Example 2: The left sawing machine 1 clamps the material 7 to be processed on the inner side, and a chip collection port 3 is provided below the material 7 to be processed. The copper chip collection device is used to simultaneously suck the sawdust generated during the sawing process to a centralized location for storage, so as to facilitate its pressing into copper blocks. The RT15HP cyclone and filter cartridge chip suction machine is composed of a fan, a chip suction port, a cyclone cartridge, a filter cartridge, a chip collection funnel, a discharge valve, and a backwash device. A sizing device 17 is provided behind the automatic material storage rack 8. The sizing device 17 is fixedly mounted above the mobile base 14. The sizing device 17 is used to measure and transmit the length of the finished ingot. The rubber-coated roller installed under the roller can fit tightly with the bar through two sets of springs. The decoder and encoder are used for sizing, and the clamps are commanded to clamp the material synchronously. The sizing range of the sizing mechanism is: 500-1400mm, and the material sizing accuracy is ±2mm.

[0022] Example 3 Automatic mode (for bars with diameters of 200 / 235 / 330 and lengths of 500mm-1400mm) The equipment automatically adjusts its height based on the incoming material diameter using a lifting and adjustable clamping device and a lifting and adjustable discharge roller table. The bar is also sized using a floating sizing device (decoder and encoder). When the bar reaches the finished bar size, the lifting and adjustable clamp clamps the bar, and the sawing unit slowly retracts according to the traction speed using a hydraulic retraction device. Simultaneously, the sawing unit cuts the bar using the sawing machine's feed mechanism, while a follow-up laser coding device applies a code to the end surface. When the sawing machine is about to saw the bar, the follow-up discharge clamping device presses the bar at the discharge end, and at the same time the lifting and adjustable discharge roller starts feeding (saw belt safety protection function); when the finished bar reaches the lifting and blocking position, the lifting and adjustable discharge roller stops rotating, and the sawing machine continues to move with the bar. When it is close to the docking position of the lifting and docking roller, the lifting and adjustable clamping device releases the bar, and the discharge roller drops from the lifting and blocking position to transport the finished bar to the docking unit of the lifting and docking roller. At the same time, the sawing machine returns to the original position through the hydraulic retraction device, waiting for the signal from the floating sizing device to perform a cyclic action.

[0023] Example 4 Semi-automatic mode (for 5000mm long bars) When producing long ingots, the sawing machine automatically adjusts the height of the adjustable clamping device and the adjustable discharge rollers based on incoming material information. The automatic intelligent storage system's lifting docking rollers lower to their lowest position (φ330). A manual clamping button is pressed based on the length, and the sawing process begins. After sawing, the ingot is automatically discharged to a safe distance via the adjustable discharge rollers. The resulting long ingot is manually removed (long ingots can occur in two situations: rejects and transfer to the old plant). After a certain period of sawing (adjustable based on actual production conditions), the long ingot is locked with a flashing and beeping signal. If the operator fails to remove the ingot in a timely manner after sawing, and continued pulling would cause a collision with the rear equipment, the sawing system issues a stop command to the hauling machine. When producing φ330 long copper ingots, the ingot can be lifted onto the transition rollers after sawing, lifting the ingot's head to prevent collisions between the ingot and the equipment.

[0024] Working principle: When the horizontal continuous casting high-speed follow-up sawing device is in use, the material to be processed is placed into the left saw machine 1, and then the material is pressed by the rear pressing structure. At this time, the material is sawed and processed. At the same time, the processed material is transferred through the feed and discharge rollers 9 on the automatic storage rack 8. When sawing the material, the copper chip collection device is used to suck the saw chips generated during the sawing process into a centralized location for storage, so as to facilitate pressing it into copper blocks. It adopts RT15HP cyclone and filter cartridge chip suction machine, which consists of a fan, a chip suction port, a cyclone, a filter cartridge, a chip collection funnel and a discharge valve, and a backwashing device. When sawing the material, the angle of the saw blade needs to be adjusted according to the needs. Since the smaller the steering angle of the saw blade, the longer the service life, compared with the current situation where the saw blade adjustment angle is generally 90° on the market, the present application can complete the rotation of the saw blade by adjusting the saw blade by only 45°, thereby improving the service life of the device, thereby solving the problem that conventional saw blades on the market often need to rotate 90° when working, and the rotation amplitude is too large, affecting the service life of the equipment. The front clamping structure features an unpowered roller conveyor above the front section, with a high-strength spring at the bottom to ensure the roller is not subjected to significant pressure when the upper pressure cylinder is tightened. The lower pressure plate is connected to the roller via a turbine T-type lead screw elevator. The stroke is 100mm, and the lead screw is a Tr90, guided by four 70mm diameter guide posts. A set of diagonal braces at the rear ensures sufficient rigidity. The sizing device 17 measures and transmits the length of the finished ingot. A rubber-coated roller mounted below the roller conveyor is secured to the bar by two sets of springs. Sizing is performed using a decoder and encoder, commanding the clamps to clamp the material synchronously. The sizing mechanism has a sizing range of 500-1400mm, with a material sizing accuracy of ±2mm. This device can be used in automatic mode and semi-automatic mode. The working methods of the two modes are as follows: In automatic mode (for three types of bar materials with diameters of 200 / 235 / 330 and lengths of 500mm-1400mm), the equipment automatically adjusts the height according to the incoming material diameter through the lifting and adjustable clamping device, the lifting and adjustable discharge roller automatically adjusts the height, and the bar material is sized by the floating sizing device (decoding, encoder). When the bar material reaches the finished bar material size, the lifting and adjustable clamp clamps the bar material, and the sawing unit slowly retreats according to the traction speed through the hydraulic retraction device. At the same time, the sawing unit cuts the bar material through the sawing machine feed mechanism, and the follow-up laser coding device codes on the end face. When the sawing machine is about to cut the bar material, the follow-up discharge device The material pressing device presses the bar at the discharge end, and at the same time the lifting and adjustable discharge roller starts feeding (saw belt safety protection function); when the finished bar reaches the lifting and blocking position, the lifting and adjustable discharge roller stops rotating, and the sawing machine continues to move with the bar. When it approaches the docking position of the lifting and docking roller, the lifting and adjustable clamping device releases the bar, and the lifting and blocking position drops the discharge roller to transport the finished bar to the docking unit of the lifting and docking roller. At the same time, the sawing machine returns to the origin position through the hydraulic retraction device, waiting for the signal from the floating sizing device to perform a cyclic action.

[0025] In semi-automatic mode (for 5000mm long bars), the sawing machine automatically adjusts the height of the adjustable clamping device and the adjustable discharge roller according to the incoming material information. The automatic intelligent storage system's lifting and docking rollers are lowered to the low position (φ330). The operator manually presses the clamping button according to the length, and the sawing process is started. After sawing, the bar is automatically discharged to a safe distance via the adjustable discharge roller. The final long ingot is lifted off manually (long bars will appear in two situations: unqualified products and transfer to the old factory). The long ingot will flash and beep when sawing for a certain period of time (adjustable according to the actual situation of the production process). A certain period of time after the sawing is completed, if the operator fails to lift the sawn ingot away in time, and the ingot continues to be pulled away and collides with the rear equipment, the sawing system will issue a stop production command to the traction machine. When producing ∅330 long copper ingots, after the sawing is completed, when the ingot runs to the transition lifting roller, the transition lifting roller will be lifted to lift the head of the ingot to avoid collision between the ingot and the equipment.
