[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0029] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , Figure 1 It is a schematic diagram of the overall structure of a semi-automatic cutting machine.

[0030] Semi-automatic cutting machines are mechanical equipment used for plate processing and are widely used in furniture manufacturing, wood product processing and other industries. Semi-automatic cutting machines are usually equipped with a tool driven by a spindle motor, and are usually operated by buttons or handles. The operator manually operates these control components and issues instructions to control the operation of the equipment, such as starting and stopping the cutting device, adjusting the cutting speed, etc. The operator first places the plate on the workbench and uses the positioning device to preliminarily position and fix the plate. Then, the cutting parameters, such as cutting path, tool speed, feed speed, etc., are manually set through the control system. After the settings are completed, the cutting device is started, and the transmission system drives the cutting device to cut the plate according to the preset path.

[0031] A semi-automatic cutting machine is provided, comprising a frame 100, wherein a material pushing unit 200 and a material cutting unit 300 are respectively disposed at the rear end and the front end of the frame 100.

[0032] The material pushing unit 200 includes a material pushing assembly slidably arranged along the length direction of the frame 100 and a machine plate 110 arranged on the frame; the material cutting unit 300 includes a slotting platform 310 arranged at the front end of the frame 100 and docked therewith, a gantry 320 connected to the slotting platform 310, and a material discharging unit 400 connected to the front end of the gantry 320. The gantry 320 is provided with double-sided guide rails at the lower and upper parts of the frame 100, and a punching and slotting unit arranged thereon is provided on the double-sided guide rails near the slotting platform 310, and a cutting unit for cutting products is provided on the other side.

[0033] In the cutting machine, the gantry is a key component, which provides support for the cutting tool, suction cup and other components of the cutting machine, so that they can work in the correct position and ensure the accuracy and quality of plate processing. At the same time, the gantry can move left and right along the base through the guide device, driving the components installed on it to move together, so as to realize the processing of different positions of the plate. Through the movement of the gantry and the coordination of the components installed on it, plates of different sizes and shapes can be processed, which increases the processing flexibility and application scope of the cutting machine, for example, it can realize the cutting of large-format plates and the contour processing of complex-shaped plates.

[0034] As a further improvement of the above technical solution, in some further specific examples, a plurality of material blocking assemblies for fixing the product are provided on the machine tool plate 110; the material blocking assemblies include material blocking plates arranged on both sides of the product and a front positioning cylinder close to the grooving platform, and the telescopic end of the front positioning cylinder is provided with a positioning rod passing through the machine tool plate.

[0035] The positioning cylinder controls the air intake and exhaust through the instructions of the control system, thereby realizing the extension and retraction of the piston rod. When the control system introduces compressed air into the air inlet of the positioning cylinder, the compressed air pushes the piston to move in the cylinder, and the piston drives the external positioning component to move through the piston rod, accurately positioning the plate at the preset position. When the plate needs to be released, the control system controls the exhaust port to open, the compressed air in the cylinder is discharged, the piston rod retracts under the action of the return spring or other external force, and the positioning component releases the plate.

[0036] As a further improvement of the above technical solution, in some further specific examples, a plurality of guide grooves are opened on the machine tool plate 110 along its length direction; the pushing assembly includes a guide plate slidably connected to both sides of the frame and a first cylinder between the guide plates, a base is hinged at the lower end of the first cylinder, an upper clamp is connected to the telescopic end of the first cylinder in the base, and the upper clamp is hinged in the base.

[0037] In this embodiment, the first cylinder adopts a TN cylinder, which is a common dual-axis cylinder and adopts an embedded body installation and fixing form. Compared with other types of cylinders, it can effectively save installation space and make the structure of the device more compact. The first cylinder can also adopt other types of cylinders, such as SC cylinders, and the number of first cylinders can be set according to actual needs.

[0038] As a further improvement of the above technical solution, in some further specific examples, a groove opening is provided on the groove platform 310 , and the guide groove is extended to the groove platform 310 .

[0039] As a further improvement of the above technical solution, in some further specific examples, the punching and grooving unit includes a punching unit 311 slidably arranged on the upper double-sided guide rail member and grooving units 312 and 313 respectively arranged on the upper and lower double-sided guide rail members; the punching unit and the grooving unit have the same structure and both include an X-axis slide slidably arranged on the double-sided guide rail member and a Z-axis cylinder connected to the X-axis slide, a Z-axis slide is provided at the telescopic end of the Z-axis cylinder, a spindle motor 1 is connected to the Z-axis slide, and a tool changing seat is also connected to one side of the gantry close to the punching unit.

[0040] The punching and grooving unit and the spindle motor are driven by an AC servo motor. The working principle of the AC servo motor is based on the law of electromagnetic induction. When three-phase AC is applied to the stator winding, a rotating magnetic field is generated inside the motor. Under the action of this rotating magnetic field, the rotor will generate an induced electromotive force and an induced current. The induced current interacts with the rotating magnetic field to generate an electromagnetic torque, causing the rotor to rotate with the rotating magnetic field. By accurately controlling the magnitude, frequency and phase of the current in the stator winding through the servo driver, the characteristics of the rotating magnetic field can be changed, thereby achieving precise control of the motor speed, position and torque.

[0041] As a further improvement of the above technical solution, in some further specific examples, the cutting unit includes two groups of dual-axis movable units 314 and 315 which are respectively slidably connected to the double-sided guide rails, and the dual-axis movable unit includes X-axis and Z-axis motion modules connected in sequence, the X-axis motion module is slidably connected to the double-sided guide rails, the Z-axis motion module is connected to a spindle motor 2, and a cutting spindle is connected between the two groups of spindle motors 2.

[0042] The second spindle motor is driven by an AC servo motor, which has high precision, fast response speed, wide speed regulation range and smoother operation.

[0043] As a further improvement of the above technical solution, in some further specific examples, racks are provided on both sides of the double-sided guide rail members, and the punching unit, grooving unit and dual-axis movable unit are all connected to a reduction motor, and the rotating end of the reduction motor is meshed with a gear with the rack.

[0044] The working principle of the reduction motor is based on the principle of gear transmission. The high-speed, low-torque power output by the motor body is transmitted to the reduction gearbox through the input shaft. In the gearbox, the driving gear and the driven gear mesh with each other. Since the number of teeth of the driving gear is small and the number of teeth of the driven gear is large, according to the inverse relationship between the speed ratio and the number of teeth ratio of the gear transmission, the speed of the driven gear will decrease and the torque will increase. After multi-stage gear transmission, the final output shaft drives the load to run at a lower speed and a larger torque, thereby meeting the working requirements of the cutting machine.

[0045] As a further improvement of the above technical solution, in some further specific examples, the Z-axis motion module includes a linear guide rail installed on the outer wall of the X-axis motion module and a Z-axis moving plate slidably connected to the linear guide rail. The X-axis motion module is also rotatably connected to a screw rod, the Z-axis moving plate is threadedly connected to the screw rod, and the spindle motor is connected to the outer wall of the Z-axis moving plate.

[0046] The working principle of the screw is to convert rotary motion into linear motion or linear motion into rotary motion. Take the ball screw as an example. When the motor drives the screw to rotate, the spiral groove on the screw will push the ball to roll in the spiral groove of the nut. Since the nut is fixedly connected to the workbench and other components, and the screw can rotate freely, the nut will move linearly along the axis of the screw, thereby driving the workbench and other components to achieve precise linear positioning and movement. Conversely, when the external force pushes the nut to move linearly along the axis of the screw, the nut will drive the screw to rotate, converting the linear motion into rotary motion.

[0047] As a further improvement of the above technical solution, in some further specific examples, the discharging unit 400 includes two sets of material guide tables connected to the gantry 320, and the cutting spindle is arranged between the two sets of material guide tables to cut the product along the X-axis. The two sets of material guide plates have the same structure and both include an upper pressure roller group 410 and a lower pressure roller group 420. A Z-axis drive module is provided between the upper pressure roller group 410 and the material guide table.

[0048] During the plate processing, the pressure roller group maintains the pressing force on the plate on the one hand, and on the other hand, the pressure roller will rotate with the feeding movement of the plate or the movement of the tool. The rotation reduces the friction between the pressure roller and the plate to avoid affecting the feeding speed of the plate or causing scratches on the surface of the plate due to excessive friction, so that the plate can pass smoothly through the tool for cutting, grooving and other processing operations.

[0049] As a further improvement of the above technical solution, in some further specific examples, a pressure roller groove is concavely provided on the material guide table, and the lower pressure roller group 420 is rotatably arranged on the lower end surface of the material guide table and the top is embedded in the pressure roller groove; the Z-axis drive module includes a Z-axis rack arranged on the material guide table along the Z-axis direction and a Z-axis motor drive member meshing with the Z-axis rack, the Z-axis motor drive member is connected to the fixed end of the upper pressure roller group 410, and a notch is provided on the material guide table along the Z-axis direction to cooperate with the upper pressure roller group.

[0050] The rack in this embodiment can also be replaced with a screw rod or other structure and component with similar functions.
