Description

Technical Field

[0001] The present invention relates to the technical field of metal cutting, and in particular to a metal workpiece raw material cutting device with a precise positioning function. Background Art

[0002] Metal processing is a core process in the manufacturing industry. The efficiency and quality of metal processing will greatly affect the development of the manufacturing industry. For subsequent processing operations, metal raw materials usually need to be processed. Common processing methods include: flame cutting, water cutting, wire cutting and traditional saw blade cutting, etc. Saw blade cutting is a common way to rough process plates. It is a cold cutting method. It usually uses a ring-shaped endless band saw blade as the saw tool. It is a saw machine that wraps around two saw wheels and makes a unidirectional continuous linear motion to saw metal plates.

[0003] Mechanical cutting is the most common cutting method in this field. It has obvious effects in cutting aluminum, cast iron, steel, etc., and is more suitable for pipes and bars. However, with the continuous improvement of industrial requirements, general cutting equipment can no longer meet the cutting accuracy required now. In addition, this method is more harmful to the saw blade, which often leads to a shorter service life of the saw blade. At the same time, it can also cause the band saw blade to break, which will also affect the personal safety of surrounding operators. Summary of the Invention

[0004] The purpose of the present invention is to provide a metal material cutting device with a precise positioning function to solve the problems raised in the prior art.

[0006] The cutting device includes a cutting bed, a lifting platform is provided on the cutting bed, the lifting platform is slidably connected to the cutting bed, a cutting mechanism is provided on the lifting platform, a band saw blade is provided on the cutting mechanism, a lifting motor is provided in the cutting bed, a sliding gear is provided on the output end of the lifting motor, a sliding wedge is provided on the cutting bed, teeth are provided at the bottom end of the sliding wedge, the sliding gear meshes with the teeth on the sliding wedge, the sliding wedge is slidably connected to the lifting platform, a positioning support frame is provided on the cutting bed, a mounting groove is provided on the positioning support frame, a spiral extrusion plate is provided in the mounting groove, the spiral extrusion plate is slidably connected to the mounting groove, a positioning module is provided in the mounting groove, the positioning module is electrically connected to the lifting motor through a wire, and when cutting, the metal raw material needs to be Installed in the installation slot, the internal positioning module will position the end of the metal raw material and find the best cutting point. Then the spiral extrusion plate in the installation slot will tighten the metal raw material. Then the lifting motor drives the sliding wedge to move. Under the action of the wedge surface, the sliding wedge will drive the lifting platform to move up and down on the cutting bed, so that the raw material can be cut at different depths. The band saw blade is a cutting band saw blade with a certain angle. The cutting mechanism drives the band saw blade to cut the metal raw material. At the same time, the band saw blade will generate heat and vibration, which will be collected and fed back in time to adjust the progress of the lifting motor. At the same time, it also indirectly adjusts the gear of the cutting mechanism to adapt to the cutting of metal raw materials of various materials and models.

[0007] A motor mounting seat is provided on the lifting platform, a limit column is provided on the lifting platform, the limit column is slidably connected to the cutting bed, a pressurized water gun is provided on the lifting platform, a water supply tank is provided in the cutting bed, the water supply tank is connected to the pressurized water gun through a conduit, and a pressure pump is provided in the water supply tank. During cutting, it is very important to cool down the band saw blade. If the cooling is not guaranteed, the life of the band saw blade will be sharply reduced, and problems such as breakage or deformation may occur at any time. Water is supplied to the pressurized water gun through the pressure pump, and the pressurized water gun will flush and cool the band saw blade, which can not only cool down the band saw blade in time, but also remove debris adhering to the band saw blade in time.

[0008] The cutting mechanism includes a cutting motor, a transmission wheel is provided on the output end of the cutting motor, a transmission sub-wheel is rotatably connected to the lifting platform, the cutting motor is arranged on the motor mounting seat, a pulley is provided between the transmission sub-wheel and the transmission wheel, and the band saw blade is arranged on the transmission wheel and the transmission sub-wheel. The cutting motor drives the transmission wheel to rotate, and the transmission wheel drives the transmission sub-wheel to rotate through the pulley. The transmission wheel cooperates with the transmission sub-wheel to drive the band saw blade to operate. While the pulley reduces the transmission loss, it also reduces the friction damage of the transmission sub-wheel to the band saw blade.

[0009] A feedback component is provided on the lifting platform, which includes a feedback splint. The band saw blade passes through the feedback splint. Feedback cavities are respectively provided on the sides of the feedback splints close to each other. Multiple elastic switches are provided in each feedback cavity. A feedback diaphragm is provided on each feedback cavity. The feedback diaphragm is in sliding contact with the elastic switch. The feedback diaphragm is located on both sides of the band saw blade. The elastic switch is electrically connected to the lifting platform, and the elastic switch is electrically connected to the lifting motor. When cutting, metal raw materials of different models and materials will have different resistances, so the resistance received by the band saw blade will also be different. When encountering materials with greater rigidity, the vibration generated by the band saw blade will increase, and the amplitude of the vibration will also increase, and will be transmitted to the feedback diaphragm. The feedback diaphragm will transmit the vibration to the elastic switch. When the elastic switch is subjected to sufficient force, it will transmit a trigger signal, thereby adjusting the operating speed of the lifting motor, so that the lifting speed of the lifting motor is reduced, reducing the risk of the band saw blade breaking, and also ensuring that the end face of the metal raw material is neat.

[0010] The feedback component also includes a temperature measuring frame, a windshield is provided on the temperature measuring frame, a through slot is provided on the windshield, the band saw blade passes through the through slot, a debris removal rubber sleeve is provided on the through slot, a temperature sensing resistor is provided on the temperature sensing resistor, a detection strip is provided on the temperature sensing resistor, a contact wheel is provided on the detection strip, the contact wheel is rotatably connected to the detection strip, the temperature sensing resistor is electrically connected to the cutting motor and the pressure pump through a wire, during the cutting process, the continuous cutting of the band saw blade will cause the band saw blade to heat up, and the temperature measuring frame will detect the windshield, the contact wheel It will come into direct contact with the band saw blade and transfer the heat to the detection strip, which then transfers the heat to the temperature-sensitive resistor. The temperature-sensitive resistor senses the temperature and its resistance value changes, thereby adjusting the gear of the cutting motor. When encountering harder metal materials, the cutting motor rotates faster, and vice versa, the cutting motor rotates slower and controls the water outlet speed of the pressure pump. The higher the temperature, the faster the water outlet speed of the pressure pump, and vice versa, the slower the water outlet speed of the pressure pump, thereby saving energy consumption and extending the service life of the band saw blade.

[0011] A stabilization frame is provided on the lifting platform, and a relaxation frame is provided on the stabilization frame. The relaxation frame is rotatably connected to an extrusion wheel and an extrusion sub-wheel, and the band saw blade passes between the extrusion wheel and the extrusion sub-wheel. A stabilization hydraulic rod is provided on the lifting platform, and the stabilization hydraulic rod is electrically connected to the elastic switch through a wire. During the cutting process, after the elastic switch is triggered, the stabilization hydraulic rod will drive the relaxation frame to move, and the extrusion wheel and the extrusion sub-wheel on the relaxation frame are driven by the relaxation frame, so that the band saw blade can be tightened, reducing the vibration generated by the band saw blade, which will reduce the cutting accuracy. At the same time, the band saw blade can also be adjusted for emergency treatment to avoid breakage.

[0012] A threaded rod is provided on the spiral extrusion plate, which engages with the threaded hole on the mounting groove. A fastening rod is slidably connected to the threaded rod. A fastening plate is provided on the side of the mounting groove away from the spiral extrusion plate. An auxiliary spring is provided on the fastening plate. The two ends of the auxiliary spring respectively press against the fastening plate and the mounting groove. When installing the metal raw material, the threaded rod is driven to rotate by the fastening rod, so that the spiral extrusion plate can be close to the workpiece. Under the action of the auxiliary spring, the fastening plate is always close to the metal raw material, thereby ensuring the degree of engagement between the threaded rod and the mounting groove, which can avoid the problem of loose threads when the metal raw material is installed.

[0013] The positioning module includes a positioning frame, which is arranged in a mounting slot, the mounting slot is rotationally connected to the cutting bed, a positioning wheel is provided on the mounting slot, a positioning motor is provided in the cutting bed, a positioning rod is provided at the output end of the positioning motor, and the thread on the positioning rod is engaged with the teeth on the positioning wheel. In order to adapt to cutting operations at different angles, the positioning motor will drive the positioning rod to rotate, and the thread on the positioning rod drives the positioning wheel to rotate, which indirectly causes the mounting slot to deflect, thereby realizing multi-angle positioning operations.

[0014] The positioning mold also includes multiple contact strips and contact frames, each contact strip is respectively provided with a contact switch, adjacent contact strips are slidingly connected, the contact strips are slidingly connected to the contact frame, a positioning plate is provided in the contact frame, the positioning plate is slidingly connected to the contact frame, and a reset spring is provided between the positioning plates and the contact frame, and each contact strip is respectively pressed against the positioning plate on the side away from the contact switch, and the contact switch is electrically connected to the cutting motor through a wire. When positioning is performed, the uneven metal raw material port will press against the contact strip and trigger the corresponding contact switch, and the shape of the end face can be indirectly obtained. When the adjacent contact switches are triggered and the signal forms a complete closed area, the spiral extrusion plate can be tightened at this time. After the cutting is completed, the positioning plate will be restored to its initial state under the action of the reset spring, and wait for the next positioning operation.

[0017] 2. The present invention adopts a structural component with automatic detection and feedback of the band saw blade, which can detect the vibration and temperature of the band saw blade.

[0018] 3. The present invention adopts an automatic pressurized water spraying structural component. By feedback on the temperature of the band saw blade, the water spraying power can be adjusted, so that the spraying speed of the pressurized water gun can be adjusted in time to ensure the normal operation of the band saw blade, reduce the adhesion of debris, and cool down in time to avoid deformation of the band saw blade and improve the product yield.
