Description

Technical Field

[0001] The invention belongs to the technical field of casting processing, in particular to a casting numerical control sawing device. Background Art

[0002] A casting is an object with a certain shape, size and performance obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then polishing and other subsequent processing methods. After the casting is formed, in order to obtain the appropriate size, the casting needs to be cut.

[0003] A Chinese patent with announcement number CN115091258B discloses a casting cutting machine that is convenient for collecting dust chips. The invention uses an exhaust fan to exhaust air in a collection box and discharge the gas from an exhaust pipe, thereby generating negative pressure in the collection box. The collection box can then be connected to a collection hood in the casing using an exhaust hose, so that the collection hood can be used to absorb the dust chips generated by the cutting. After the dust chips enter the collection box, they are filtered by the filter mesh cylinder and fall into a storage box in the collection box. When the cutting operation is completed, the sealed door of the collection box can be opened to take out the storage box, thereby recycling the dust chips collected in the storage box.

When the fixed plate 5 moves down, the fixed plate 5 located at the top will move down to the inner side of the rotating seat 2. At this time, the casting that has been cut above will be separated from the fixed plate 5, and the casting will slide out along the arc groove at the top to realize automatic unloading. Through the above scheme, the casting can be automatically fixed and the casting can be automatically released after the casting is cut. There is no need to reciprocate and adjust the clamp, which increases the convenience of using the device. The fixing and releasing of the casting are carried out simultaneously, saving working time. The casting that has been cut can be automatically detached from the device after being released, realizing automatic unloading, and effectively improving the working efficiency of the device.

[0025] like Figure 1 to Figure 2As shown, a vertical plate 9 is provided on one side of the rotating seat 2, and two mounting plates 10 are fixedly installed on the outer wall of the vertical plate 9, and arc-shaped positioning plates 11 are fixedly installed on the side of the two mounting plates 10 away from the vertical plate 9, and the two arc-shaped positioning plates 11 are both slidably connected with the rotating seat 2; the arc-shaped positioning plates 11 are connected to the vertical plate 9 by the mounting plates 10, so as to fix the position of the arc-shaped positioning plates 11, and the arc-shaped positioning plates 11 are located on the outer side of the rotating seat 2 to limit the rotating seat 2, and when the rotating seat 2 rotates, the arc-shaped positioning plates 11 can increase the stability of the rotating seat 2 during rotation.

[0026] like Figure 1 to Figure 2 and Figures 7 and 8 As shown, the cutting assembly includes a driving motor 12, which is fixedly mounted on the inner wall of the arc-shaped positioning plate 11 located above, and a cutting knife 13 is fixedly mounted on the output shaft of the driving motor 12, and the cutting knife 13 is located on the side of the rotating seat 2 away from the vertical plate 9, and a connecting shaft 14 is symmetrically fixedly mounted on the outer wall of the arc-shaped positioning plate 11 above, and a protective cover 15 is fixedly mounted between the two connecting shafts 14, and the protective cover 15 is sleeved on the outer side of the cutting knife 13; the cutting assembly is fixed on the arc-shaped positioning plate 11 located above, and when cutting, the driving motor 12 The cutting knife 13 will be driven to rotate, and the rotating seat 2 will drive the casting to rotate.

When the end face of the casting coincides with the end face of the cutting knife 13, the cutting work is completed. The protective cover 15 is sleeved on the outside of the cutting knife 13. The protective cover 15 prevents the operator from being mechanically injured in an accident. At the same time, it can also prevent the high-speed cutting material or friction sparks generated during the cutting process from causing safety hazards to the operator.

[0027] like Figure 1 As shown, a blanking plate 16 is fixedly installed on the side of the lower arc-shaped positioning plate 11 away from the vertical plate 9, and the blanking plate 16 is located below the cutting knife 13; when the cutting work is completed, the cut waste will fall on the inner side of the blanking plate 16, and then the waste will slide down the blanking plate 16 under the action of its own gravity, thereby achieving the effect of automatically collecting the waste.

[0028] like Figure 1 to Figure 2 and Figure 5As shown, a torsion spring shaft 17 is fixedly installed on the inner wall of the arc-shaped positioning plate 11 below, and buffer rods 18 are fixedly installed at both ends of the torsion spring shaft 17; in the initial state, the buffer rod 18 will be vertically upward under the action of the torsion spring shaft 17, and at this time, the two sides of the arc-shaped groove below will be blocked by the buffer rod 18, and when the casting enters the arc-shaped groove, the casting will conflict with the buffer rod 18, and the buffer rod 18 will rotate under the extrusion of the casting. The buffer rod 18 will give the casting a certain resistance under the action of the torsion spring shaft 17, so that the speed at which the casting slides down will be slowed down, thereby preventing the casting from sliding down too fast and colliding with the rotating seat 2 and being damaged, thereby protecting the casting.

[0029] like Figures 5 and 6 As shown, a slider 19 is slidably installed on the inner wall of the buffer rod 18, an elastic member A20 is fixedly installed between the outer wall of the slider 19 and the inner wall of the buffer rod 18, a force plate 21 is fixedly installed on the outer wall of the slider 19 and located on the outside of the buffer rod 18, and an elastic baffle 22 is fixedly installed on the outer wall of the force plate 21; in the initial state, the elastic member A20 is in a contracted state, and in the process of the casting squeezing the buffer rod 18 to rotate the buffer rod 18, the casting will also contact and squeeze the elastic baffle 22, and the elastic baffle 22 will cause the force plate 21 to drive the slider 19 to move after being squeezed, and the elastic member A20 will be stretched when the slider 19 moves, and the casting can be blocked by the reverse elastic force of the elastic member A20, thereby reducing the speed at which the casting slides down, further protecting the casting, and preventing the casting from colliding with the equipment and being damaged.

[0030] like Figure 2 and Figure 8 As shown, a screw 23 is threadedly installed on the inner wall of the vertical plate 9, and a calibration plate 24 is rotatably installed on one end of the screw 23, and a swivel 25 is fixedly installed on the other end of the screw 23. A limiting groove 26 is provided on the top of the mounting plate 10 below, and a limiting block 27 is fixedly installed on the bottom of the calibration plate 24, and the outer wall of the limiting block 27 is slidably connected to the inner wall of the limiting groove 26; the position of the casting is calibrated by the calibration plate 24, and the swivel 25 is rotated, and the swivel 25 drives the screw 23 to rotate, and the screw 23 drives the calibration plate 24 to move by cooperating with the thread of the vertical plate 9. The calibration plate 24 is moved to a suitable position according to cutting needs. After the casting is placed, the casting is pushed so that one end of the casting fits with the calibration plate 24, so that the position of the casting can be calibrated, which makes it easy to quickly calibrate the casting and facilitate cutting.

[0031] like Figure 1 to Figure 2 and Figures 9 and 10As shown, a base 28 is fixedly installed at the bottom of the vertical plate 9, a slide 29 is fixedly installed at the top of the base 28, a push plate 30 is slidably installed on the inner wall of the slide 29, and a plurality of elastic members B31 are fixedly installed between the outer wall of the push plate 30 and the inner wall of the slide 29, a rotating shaft 32 is rotatably installed on the inner wall of the base 28, an extrusion plate 33 is rotatably installed on the outer wall of the rotating shaft 32, an extrusion roller 34 is rotatably installed on the side of the extrusion plate 33 away from the rotating shaft 32, the extrusion roller 34 overlaps the push plate 30, and a pedal 35 is fixedly installed on the outer wall of the extrusion plate 33; when calibrating the position of the casting, the worker When the operator steps on the pedal 35, the pedal 35 will cause the squeezing plate 33 to rotate downward around the rotating shaft 32 after being pressed. When the squeezing plate 33 rotates, it will drive the squeezing roller 34 to move with it. When the squeezing roller 34 moves, it will squeeze the push plate 30 to move the push plate 30 toward the casting. When the push plate 30 moves, it will push the casting so that one end of the casting fits with the calibration plate 24. The operation is simpler and more convenient by stepping on it, which is convenient for casting calibration and makes the device more convenient to use. After releasing the pedal 35, the push plate 30 and the squeezing plate 33 will be reset under the action of the elastic member B31.

[0032] like Figure 2 and Figure 8 As shown, a stabilizing frame 36 is fixedly installed on the outer wall of the vertical plate 9, and a collar 37 is rotatably installed on the output shaft of the drive box 1, and the outer wall of the collar 37 is fixedly connected to one end of the stabilizing frame 36; through the cooperation of the stabilizing frame 36 and the collar 37, the output shaft of the drive box 1 is limited, the pressure on the drive box 1 is reduced, and the drive box 1 is more stable when working.

[0033] Working principle: When cutting, the circular casting is transported to the equipment, and the circular casting will slide to the inner side of the rotating seat 2 through the arc groove at the bottom. At this time, the circular casting is at the lowest point of the arc groove, and then the fixed shaft 3 is moved downward under the action of the driving component. When the fixed shaft 3 moves downward, it will drive the fixed plate 5 to move downward through the connecting frame 4. When the fixed plate 5 moves downward, the fixed plate 5 located below will cooperate with the rotating seat 2 to clamp the circular casting, thereby completing the fixation of the casting. When the casting is fixed, the driving box 1 will drive the rotating seat 2 to rotate, thereby driving the casting to rotate. When the casting rotates to the top, the cutting component will cut the casting. When the fixed shaft 3 rotates to a vertical state, the cutting work is completed. At this time, the arc groove originally located at the top will rotate to the bottom, and then the new The casting to be cut slides to the inner side of the rotating seat 2 through the arc groove at the bottom, and then the fixed plate 5 is moved down under the action of the driving component to fix the newly placed casting below. When the fixed plate 5 moves down, the fixed plate 5 located above will move down to the inner side of the rotating seat 2. At this time, the casting above that has been cut will be separated from the fixed plate 5, and the casting will slide out along the arc groove at the top to realize automatic unloading. Through the above scheme, the casting can be automatically fixed and automatically released after the casting is cut. There is no need to reciprocate to adjust the clamp, which increases the convenience of using the device. The fixing and releasing of the casting are carried out simultaneously, saving working time. The casting that has been cut can automatically detach from the device after being released, realizing automatic unloading, and effectively improving the working efficiency of the device.

[0034] The cutting assembly is fixed on the arc-shaped positioning plate 11 located above. When cutting, the driving motor 12 will drive the cutting knife 13 to rotate, and the rotating seat 2 will drive the casting to rotate. The casting will move upward when rotating and get close to the cutting knife 13. When the casting contacts the cutting knife 13, the cutting knife 13 starts to cut the casting. When the end face of the casting coincides with the end face of the cutting knife 13, the cutting work is completed. The protective cover 15 is sleeved on the outside of the cutting knife 13 to prevent the operator from being mechanically injured in an accident. At the same time, it can also prevent the high-speed cutting material or friction sparks generated during the cutting process from causing safety hazards to the operator. When the cutting work is completed, the cut waste will fall on the inner side of the blanking plate 16, and then the waste will slide along the blanking plate 16 under the action of its own gravity, thereby achieving the effect of automatically collecting the waste.

[0035] In the initial state, the buffer rod 18 will be vertically upward under the action of the torsion spring shaft 17. At this time, the two sides of the arc groove below will be blocked by the buffer rod 18. When the casting enters the arc groove, the casting will conflict with the buffer rod 18. The buffer rod 18 rotates under the extrusion of the casting. The buffer rod 18 will give the casting a certain resistance under the action of the torsion spring shaft 17, slowing down the speed of the casting sliding down, thereby preventing the casting from sliding down too fast and colliding with the rotating seat 2 and being damaged, thereby protecting the casting. In the initial state, the elastic part A20 is in a contracted state. In the process of the casting squeezing the buffer rod 18 to rotate the buffer rod 18, the casting will also contact and squeeze the elastic baffle 22. After the elastic baffle 22 is squeezed, the force plate 21 will drive the slider 19 to move. When the slider 19 moves, the elastic part A20 will be stretched. Through the action of the reverse elastic force of the elastic part A20, the casting can be blocked, thereby reducing the speed of the casting sliding down, further protecting the casting, and preventing the casting from colliding with the equipment and being damaged.

[0036] The position of the casting is calibrated by the calibration plate 24, and the swivel 25 is rotated, and the swivel 25 drives the screw 23 to rotate. The screw 23 drives the calibration plate 24 to move by cooperating with the thread of the vertical plate 9. The calibration plate 24 is moved to a suitable position according to the cutting needs. After the casting is placed, the casting is pushed so that one end of the casting is in contact with the calibration plate 24, and the position of the casting can be calibrated, which is convenient for quickly calibrating the casting and facilitating the cutting work. When calibrating the position of the casting, the staff steps on the pedal 35 with their feet. After the pedal 35 is pressed, the extrusion plate 33 will rotate downward around the rotating shaft 32. When the extrusion plate 33 rotates, it will drive the extrusion roller 34 to move with it. When the extrusion roller 34 moves, it will squeeze the push plate 30 so that the push plate 30 moves toward the direction of the casting. When the push plate 30 moves, it will push the casting so that one end of the casting is in contact with the calibration plate 24. The operation is simpler and more convenient by stepping on the foot, which is convenient for casting calibration and makes the device more convenient to use.
