Description

Technical Field

[0001] This utility model belongs to the technical field of vertical metal band saws, and relates to a vertical metal band saw, particularly a vertical metal band saw. Background Technology

[0002] Band saws are machine tools used for sawing various metal materials. They are classified by structure into horizontal and vertical types; and by function into semi-automatic, fully automatic, and CNC types. Vertical band saws are common industrial equipment used for metal cutting, and are frequently used in industries such as: punching die making, shoe mold making, gravity die casting of copper and aluminum, automotive industry, hardware manufacturing and various internal equipment production lines, aerospace industry, metal lettering for signs, steel materials, machinery manufacturing, home appliances, vibratory feeders, and tire manufacturing.

[0003] The working principle of existing flame cutting machine tools is to use the heat energy generated by the combustion of oxygen and fuel gas (such as acetylene, propane, etc.) to preheat the workpiece to the ignition point of the metal before spraying out a high-speed cutting oxygen stream, which causes the preheated metal to burn and release heat, thus preheating the metal to be cut and achieving cutting. However, for domestic vertical band saws that automatically cut long iron plates into smaller iron plates using flame cutting, it is easy to cause poor cutting surface and large deformation. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in existing technologies by proposing a vertical metal band saw. The technical problem this utility model aims to solve is: how to achieve a flat metal cutting surface, minimal deformation, and simple and convenient operation.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A vertical metal band saw includes a base, a feeding and lifting cylinder fixed on the base, a feeding frame fixed to the telescopic end of the feeding and lifting cylinder, an infeed worktable fixed on the feeding frame, a magnetic scale mounted on the infeed worktable, an outlet frame fixed on the base, a motor fixed on the outlet frame, an outlet platform fixed on the outlet frame, multiple outlet wheels rotatably connected to the outlet platform, the outlet wheels fixedly connected to the output shaft end of the motor, an auxiliary worktable fixed on the outlet platform, a straight saw frame body fixed on the base, a power distribution control box and an electrical box fixed on the straight saw frame body, a movable guide arm fixed on the straight saw frame body, a saw band mounted on the guide arm, a cooling device mounted on the base, and an independent hydraulic pump station fixed on the base.

[0007] The working principle of this utility model is as follows: The main drive of this machine tool adopts variable frequency stepless speed regulation, worm gear reducer transmission, and bearings using well-known domestic bearings. The sawing speed is 0-80m / min. The independent hydraulic pump station is an independent hydraulic device, mainly used to convert mechanical energy into the pressure energy of hydraulic oil, and to control the action of hydraulic machinery through the hydraulic system. It mainly consists of a hydraulic pump, a drive motor, an oil tank, a directional valve, a throttle valve, and a relief valve. The hydraulic pump station drives the oil pump to rotate through the motor. The oil pump draws oil from the oil tank and pumps out hydraulic oil, realizing the energy conversion. The hydraulic oil is transmitted to the cylinder or oil motor of the hydraulic machinery after the hydraulic valves make fine adjustments to the direction, pressure, and flow rate through an integrated block or valve combination, thereby controlling the direction, force, and speed of the hydraulic motor and driving various hydraulic presses. The machine completes the work, with hydraulic components from well-known domestic brands. The oil tank capacity is approximately 80L or more, and the main pump of the hydraulic station is a variable pump. The main function of the movable guide arm is to guide the saw blade along the correct path for cutting, ensuring the straightness and accuracy of the cut. If the saw blade held by the guide wheel seat of the movable guide arm is not perpendicular to the saw table, or if the distance between the movable guide arms is not set properly, the sawing accuracy will decrease. The material to be cut is placed on the feeding table, guided by the movable clamp, and the feeding frame is lifted by the feeding lifting cylinder to feed the material. The feeding length is input through the intelligent touch screen and positioned by the magnetic ruler. After the saw blade is cut, the motor is started to drive the output wheel to rotate, and the material is delivered by the output table. The cycle continues, achieving the characteristics of a flat cut surface, small deformation, and simple and convenient operation.

[0008] Two fixed micro-motion clamps are fixed on the front side of the feeding worktable, and an electric telescopic rod is fixed on the rear side of the feeding worktable. Two movable clamps are fixed on the telescopic end of the electric telescopic rod, and multiple guide wheels are rotatably connected to the feeding worktable.

[0009] Using the above structure, by installing movable clamps and guide wheels, the movable clamps are hydraulically controlled to clamp and fix the sawing component. Then, the electric telescopic rod is activated to drive the movable clamps to move the sawing component, so that the other end of the sawing component moves to the position of the fixed micro-clamp. The fixed micro-clamp then clamps and fixes the other end of the sawing component, thereby adjusting the position of the sawing component, guiding and fixing the sawing component, and ensuring sawing accuracy.

[0010] The feeding rack adopts a square steel tube welded structure, the base is an integral welded structure, and the feeding lifting cylinder adopts a four-column double hydraulic cylinder for lifting the material, with a lifting load of 50 tons.

[0011] By adopting the above structure, with the feeding frame made of square steel pipe welded structure and the base being an integral welded structure, the machine tool has sufficient rigidity and the feeding is more stable.

[0012] A reducer is fixed inside the main body of the straight saw frame. A pulley is fixed to the output shaft end of the reducer. A pulley is rotatably connected to the lower end of the main body of the straight saw frame. The pulley is connected to the pulley through the saw belt. A hydraulic tensioning device is provided between the pulley and the pulley.

[0013] Using the above structure, a hydraulic tensioning device (a current technology) is employed. The closed-loop control system of the hydraulic tensioning device mainly consists of a tensioning cylinder, an electromagnetic directional valve, a proportional relief valve, a force sensor, and a controller. The hydraulic pump draws in hydraulic oil through the suction pipe and delivers pressurized oil to the hydraulic cylinder through the pressure pipe. The piston or plunger inside the hydraulic cylinder moves under the pressure of the oil, causing the pulley to rotate or move, thus achieving the tensioning function. A control valve, located between the hydraulic pump and the hydraulic cylinder, regulates the flow and pressure of the hydraulic oil. The tension is adjustable from 4-6 MPa, ensuring that the saw band maintains appropriate tension during sawing, avoiding problems such as insufficient or excessive tension leading to sawing quality issues, premature cracking, or breakage of the saw band.

[0014] An electrical box is placed on the rear side of the base. The electrical box is a cabinet type. Electrical components, frequency converters, and transformers are installed inside the electrical box. The frequency converters, transformers, and electrical components are arranged in different cavities inside the electrical box. An operation panel is fixed on the upper part of the electrical box. The operation panel is equipped with electrical control buttons and an intelligent touch screen.

[0015] With the above structure and the installation of the electrical box, the entire electrical system is configured as follows: the frequency converter is selected from well-known domestic products, which achieves the stability and reliability of electrical components, extends service life, and greatly reduces the electrical failure rate.

[0016] The cooling device includes a water tank fixed on the base, with an overflow hole on the water tank. Cooling boxes are fixed inside the feeding lifting cylinder, motor, electrical box, and straight saw frame. The cooling boxes are connected to the water tank through a circulating water pipe, and a water pump is installed on the circulating water pipe. A coolant return device connected to the circulating water pipe is installed inside the cooling box.

[0017] By adopting the above structure and installing a cooling device, the water in the storage tank is dispersed into the cooling box by the operation of the water pump. This achieves the absorption and cooling of the heat generated during the operation of the feeding lifting cylinder, motor, electrical box, and straight saw frame. When the water has absorbed enough heat, the coolant return device automatically returns it to the storage tank pump station for automatic circulation. The water tank is equipped with an overflow hole to ensure that the motor will not be damaged due to accidental overfilling of water. It also ensures the stability and continuity of the reaction system, ensuring that the overall machine design is reasonable and there is no overflow phenomenon.

[0018] Compared with existing technologies, this vertical metal band saw has the following advantages:

[0019] 1. The main drive of this machine tool adopts variable frequency stepless speed regulation and worm gear reducer transmission. The bearings are well-known domestic bearings. The sawing speed is 0-80m / min. The independent hydraulic pump station is an independent hydraulic device, mainly used to convert mechanical energy into the pressure energy of hydraulic oil, and to control the action of hydraulic machinery through the hydraulic system. It mainly consists of a hydraulic pump, a drive motor, an oil tank, a directional valve, a throttle valve, and a relief valve. The hydraulic pump station drives the oil pump to rotate through the motor. The oil pump draws oil from the oil tank and pumps out hydraulic oil, realizing the energy conversion. The hydraulic oil is transmitted to the cylinder or hydraulic motor of the hydraulic machinery after the hydraulic valves make fine adjustments to the direction, pressure and flow through the integrated block or valve combination. This controls the direction, force and speed of the hydraulic motor, and drives various hydraulic machinery to complete the work. The hydraulic components are from well-known domestic brands, and the oil tank capacity is approximately 80L or more. The main pump of the hydraulic station is a variable pump. The main function of the movable guide arm is to guide the saw blade along the correct path for cutting, ensuring the straightness and accuracy of the cut. If the saw blade held by the guide wheel seat of the movable guide arm is not perpendicular to the saw table, or if the distance between the movable guide arms is not set properly, the sawing accuracy will decrease. The material to be cut is placed on the feeding table, guided by the movable clamp, and the feeding frame is lifted by the feeding lifting cylinder to feed the material. The feeding length is input through the intelligent touch screen and positioned by the magnetic ruler. After the saw blade is cut, the motor is started to drive the output wheel to rotate and the material is sent out by the output table. The cycle continues, achieving the characteristics of a flat cut surface, small deformation, and simple and convenient operation.

[0020] 2. By installing the electrical box, the entire electrical system is configured as follows: the frequency converter is selected from well-known domestic products, which achieves the stability and reliability of electrical components, extends service life, and greatly reduces the electrical failure rate.

[0021] 3. By installing a cooling device, the water in the storage tank is dispersed into the cooling box through the operation of the water pump, which realizes the absorption and cooling of the heat generated during the operation of the feeding lifting cylinder (2), motor (9), electrical box and straight saw frame. When the water absorbs enough heat, the cooling liquid return device can automatically return to the storage tank pump station for automatic circulation. The water tank is equipped with an overflow hole to ensure that the motor will not be damaged due to misoperation and adding too much water. At the same time, it also ensures the stability and continuity of the reaction system, and ensures that the overall machine design is reasonable and there is no overflow phenomenon.

The independent hydraulic pump station is an independent hydraulic device mainly used to convert mechanical energy into the pressure energy of hydraulic oil and control the action of hydraulic machinery through the hydraulic system. It mainly consists of a hydraulic pump, a drive motor, an oil tank, directional valves, throttle valves, and relief valves. The hydraulic pump station drives the oil pump to rotate via motor 9. The oil pump draws oil from the oil tank and pumps it out, realizing the energy conversion. The hydraulic oil, through an integrated block or valve combination, is precisely regulated in terms of direction, pressure, and flow by the hydraulic valves before being transmitted to the cylinders or hydraulic motors of the hydraulic machinery. This controls the direction, force, and speed of the hydraulic motor, driving various hydraulic machines to complete their work. The hydraulic components use well-known domestic manufacturers. The brand has an oil tank capacity of approximately 80L or more. The main pump of the hydraulic station is a variable pump. The main function of the movable guide arm 15 is to guide the saw blade 16 along the correct path for cutting, ensuring the straightness and accuracy of the cut. If the saw blade 16 held by the guide wheel seat of the movable guide arm 15 is not perpendicular to the saw table, or if the distance between the movable guide arms 15 is not set properly, the sawing accuracy will decrease. The sawing component material is placed on the feeding worktable 4, guided by the movable clamp 7, and the feeding lifting cylinder 2 lifts the feeding frame 3 to feed the sawing component material.

Two movable clamps 7 are fixed on the telescopic end of the electric telescopic rod, and multiple guide wheels 5 are rotatably connected on the feeding worktable 4.

[0031] Using the above structure, by installing the movable clamp 7 and the guide wheel 5, the movable clamp 7 is hydraulically controlled to clamp and fix the sawing component. Then, the electric telescopic rod is activated to drive the movable clamp 7 to move the sawing component, so that the other end of the sawing component moves to the position of the fixed micro-clamp 6. The fixed micro-clamp 6 then clamps and fixes the other end of the sawing component, thereby realizing the adjustment of the position of the sawing component, guiding and fixing the sawing component, and ensuring sawing accuracy.

[0032] The feeding rack 3 adopts a square steel pipe welded structure, the base 1 is an integral welded structure, and the feeding lifting cylinder 2 adopts a four-column double hydraulic cylinder to lift the material, with a lifting load of 50 tons.

[0034] A reducer is fixed inside the main body 13 of the straight saw frame. A pulley is fixed to the output shaft end of the reducer. A pulley is rotatably connected to the lower end of the main body 13 of the straight saw frame. The pulley is connected to the pulley through the saw belt 16.

The hydraulic pump draws in hydraulic oil through the suction pipe and delivers pressurized oil to the hydraulic cylinder through the pressure pipe. The piston or plunger inside the hydraulic cylinder moves under the pressure of the oil, causing the pulley to rotate or move, thus achieving the tensioning function. A control valve is located between the hydraulic pump and the hydraulic cylinder to regulate the flow and pressure of the hydraulic oil. The tension force is adjustable from 4 to 6 MPa, ensuring that the saw band 16 has appropriate tension during sawing, avoiding problems such as sawing quality issues, premature cracking, or breakage of the saw band 16 due to insufficient or excessive tension.

[0036] An electrical box 17 is placed on the rear side of the base 1. The electrical box 17 is a cabinet type. Electrical components, frequency converters and transformers are installed inside the electrical box 17. The frequency converters, transformers and electrical components are installed in different cavities inside the electrical box. An operation panel is fixed on the upper part of the electrical box 17.
