Description

Technical Field

[0001] The utility model relates to the technical field of sawing machines, in particular to a novel full-servo high-speed sawing machine. Background Art

[0002] The main parts of a sawing machine are the base, bed, column, saw beam and transmission mechanism, guide device, workpiece clamping, tensioning device, feeder, hydraulic transmission system, electrical control system, lubrication and cooling system. A sawing machine is a simple machine tool, and users will not require their sawing machines to have the functions of a machining center. Computer-controlled sawing machines not only improve the efficiency and quality of sawing for users, but more importantly, the network function of the computer will make sawing more closely connected with the rest of the CIMS and more convenient to manage.

[0003] After searching, the patent with application number 202222652606.6 discloses a new type of intelligent full-servo high-speed sawing machine, including an H-shaped double column arranged on the base for movably connecting the saw frame assembly; the front side of the H-shaped double column is slidably connected with the saw frame assembly; a servo motor for controlling the up and down movement of the saw frame assembly is arranged in the middle of the H-shaped double column; the servo motor adjusts the lifting and lowering of the saw frame assembly through the lifting screw rod; counterweight cylinders for reducing the linear load of the servo motor and adjusting the center of gravity of the saw frame assembly so that it is located at the lifting screw rod to reduce the shaking of the sawing machine are arranged at both ends of the lower part of the saw frame assembly, and precision pressure control valves and flow control valves are arranged on the counterweight cylinders for counterweighting the left and right ends of the saw frame assembly and reducing the load of the lifting screw rod. The H-shaped double column effectively reduces the deformation of the crossbeam caused by the action and reaction force of the saw blade tensioning cylinder, so that when the sawing machine runs at high speed, the sawing is stable and the sawing accuracy is high.

[0004] The above scheme has poor clamping effect on the material when cutting the material, which causes the material to shake or even tilt during cutting, which can easily damage the saw blade and pose a safety hazard. Therefore, we need to propose a new full-servo high-speed sawing machine. Utility Model Content

The driving mechanism can be a cylinder or a motor with a screw rod and other structures, as long as it can drive the feed substrate 2 to move back and forth, this method is a commonly used means in the right technology, and will not be explained in detail here;

[0022] At the upper ends of the side walls of two groups of second fixing seats 7, a first clamping mechanism 8 is connected. A second clamping mechanism 9 is installed on the feeding substrate 2. The first clamping mechanism 8 and the second clamping mechanism 9 are arranged at the same height, which is convenient for keeping the square tube to be processed horizontal. Both the first clamping mechanism 8 and the second clamping mechanism 9 include a box body 13 and a clamping component 11 reciprocally movably installed on the box body 13. The clamping component 11 is used for clamping the square tube. On two groups of first fixing seats 3, a U-shaped fixing frame 4 is installed. A cutting component 10 is installed on the fixing frame 4. The cutting component 10 is aligned with the clamping component 11 in the first clamping mechanism 8, that is, the circular saw blade in the cutting component 10 is located at the upper end on one side of the clamping component 11 in the first clamping mechanism 8, and the cutting component 10 does not interfere with the clamping component 11. At one end of the base 1 close to the second fixing seat 7, a blanking ramp 12 is installed, which is convenient for the automatically discharging of the cut square tube. Optionally, a conveying device can be installed on one side of the base 1 close to the blanking ramp 12, and the discharged square tube directly slides onto the conveying device to realize the automatic material collection.

[0023] Two groups of first fixing seats 3 and second fixing seats 7 are arranged in alignment with respect to the feeding substrate 2, and one end of the feeding substrate 2 is located at the lower end of the first clamping mechanism 8, which can make the feeding substrate 2 more stable during the moving process.

[0024] The clamping component 11 includes two groups of clamping blocks 113 reciprocally movably installed on the box body 13 and a motor 111 installed inside the box body 13 for driving the clamping blocks 113 to move. The motor is set as a forward and reverse motor, and the moving directions of the two groups of clamping blocks 113 are moving towards each other.

[0025] One end of the output shaft of the motor 111 is connected with a bidirectional lead screw 112 through a coupling. A connecting block 115 is connected to the lead screw seat of the bidirectional lead screw 112, and the clamping block 113 is fixed on the connecting block 115.

[0026] The clamping block 113 is set as a square clamping block. The two groups of clamping blocks 113 move towards each other, and rubber sheets 114 are installed on the opposite sides of the two groups of clamping blocks 113. The motor 111 drives the bidirectional lead screw 112 to rotate. The bidirectional lead screw 112 drives the two groups of connecting blocks 115 to move. The connecting blocks 115 drive the two groups of clamping blocks 113 to move towards each other until the rubber sheets 114 on the clamping blocks 113 clamp on the side surface of the square tube.

[0027] Two groups of electric push rods 5 are installed on the fixing frame 4. One end of the piston rod of the electric push rod 5 is connected with a connecting plate 6. The end of the connecting plate 6 is attached to the inner wall of the fixing frame 4, and the cutting component 10 is installed on the connecting plate 6.

[0028] The cutting assembly 10 includes a circular saw disk and a motor for driving the circular saw disk to rotate. The motor is fixed on the connecting plate 6. A protective cover is provided on the circular saw disk. The electric push rod 5 drives the connecting plate 6 to move downward, and the connecting plate 6 drives the cutting assembly 10 to move downward, so that the circular saw disk cuts the square pipe.

[0029] When in use, the square tube material to be cut is placed between the two groups of clamping blocks 113 in the clamping assembly 11, and then the motor 111 in the clamping assembly 11 on the second clamping mechanism 9 is started, the motor 111 drives the bidirectional screw rod 112 to rotate, the bidirectional screw rod 112 drives the two groups of connecting blocks 115 to move, and the connecting blocks 115 drive the two groups of clamping blocks 113 to move toward each other until the rubber sheet 114 on the clamping block 113 is clamped on the side of the square tube to achieve the positioning of the middle section of the square tube, and drive the feeding base plate 2 to move forward, so that a cutting length is reserved for the front end of the square tube, and then the motor 111 in the clamping assembly 11 on the first clamping mechanism 8 is started to achieve the positioning of the front end of the square tube, the cutting assembly 10 is operated, and the electric push rod 5 is turned on, the electric push rod 5 drives the connecting plate 6 to move downward, and the connecting plate 6 drives the cutting assembly 10 to move downward, so that the circular saw disk cuts the square tube;

[0030] After one section of cutting is completed, the clamping component 11 on the second clamping mechanism 9 is released, and the feeding substrate 2 drives the second clamping mechanism 9 to move backward, and the middle section of the square tube is clamped and positioned again by the motor 111 in the clamping component 11 on the second clamping mechanism 9, and the clamping component 11 on the first clamping mechanism 8 is released. Then the feeding substrate 2 drives the square tube to move forward to the length required for cutting, and the clamping component 11 on the first clamping mechanism 8 clamps and positions the front end of the square tube again, and the second section of the square tube can be cut. By repeating this process, continuous processing of the square tube can be achieved.
