[0038] In this embodiment, if Figure 2 As shown, there are two groups of processing devices 200, and two saw blades 210 are arranged opposite to each other. By arranging two groups of processing devices 200, the front and rear sides of the workpiece can be cut simultaneously.

[0039] Of course, according to actual conditions, in some other embodiments, only one set of processing devices 200 may be provided to facilitate cutting of castings distributed on one side or distributed in a polygonal manner.

[0040] In this embodiment, if Figure 2 As shown, the first driving mechanism 220 includes a first base 221, a first motor 222 and a transmission shaft 223; the first motor 222 and the transmission shaft 223 are both connected to the first base 221, the first motor 222 and the transmission shaft 223 are connected through a belt transmission, the saw blade 210 is connected to the transmission shaft 223, the saw blade 210 is arranged at one end of the transmission shaft 223, and is spaced apart from the saw blades 210 of another group of processing devices 200 and distributed on both sides of the casting, and is located below the automatic clamping device 300. The first motor 222 can provide a stable cutting speed to the saw blade 210 through the belt transmission.

[0041] Of course, according to actual conditions, in some other embodiments, a servo motor may be directly connected to the saw blade 210 via an output shaft, and the rotation speed of the saw blade 210 may be adjusted according to the workpiece to be cut.

[0042] In this embodiment, in order to adapt to the cutting of different castings and expand the scope of application of the machine, Figure 2 As shown, the processing device 200 also includes a distance adjustment mechanism 230, which includes a first cylinder 231 connected to the frame 100, a first base 221 connected to the frame 100 in a manner that allows it to slide back and forth, and the first base 221 is connected to a piston rod of the first cylinder 231. The first base 221 is slidably connected to a guide rail, which is fixed to the frame 100, and a cylinder body of the first cylinder 231 is fixed to the frame 100, and the first base 221 is pushed by the piston rod to slide back and forth on the guide rail.

[0043] Of course, according to actual conditions, in some other embodiments, a screw motor or a rodless cylinder can be used instead of the first cylinder 231, and the function of adjusting the distance between the two saw blades 210 by the screw motor or the rodless cylinder can be realized.

[0044] In this embodiment, in order to realize the automatic clamping and disassembly functions of the casting, as shown in FIG. Figure 3 and Figure 4As shown, the automatic clamping device 300 includes a movable clamp 310, and the movable clamp 310 includes a fixed block 311, a movable block 312 and a second cylinder 313; the fixed block 311 is slidably mounted on the frame 100 and connected to the feeding drive device 400, the movable block 312 is hinged to the fixed block 311, and the cylinder body and piston rod of the second cylinder 313 are hinged to the fixed block 311 and the movable block 312 respectively; the lower ends of the fixed block 311 and the movable block 312 are provided with a groove 314 whose shape matches the casting pouring cup. The groove 314 can realize the rapid positioning of the casting pouring cup, and the second cylinder 313 pushes the movable block 312 through the piston rod. When the movable block 312 is closed, it is in a clamping state. When the movable block 312 is released, the pouring cup falls off from the groove 314.

[0045] Of course, according to actual conditions, in some other embodiments, a clamp whose opening and closing is controlled by a servo motor can also be used to realize automatic clamping and unloading of castings; a motor, an eccentric wheel, a connecting rod and a movable block 312 can also be used to form a crank slider, and the eccentric wheel drives the connecting rod to realize the opening and closing of the movable block 312.

[0046] In this embodiment, if Figure 3 and Figure 4 As shown, a plurality of anti-collision strips 315 are arranged at intervals at the lower end of the movable block 312. The anti-collision strips 315 arranged at intervals can prevent the workpieces from colliding with each other due to uneven force when being cut by the saw blade 210.

[0047] Of course, according to actual conditions, in some other embodiments, an anti-collision plate may be provided at the lower end of the movable block 312 to avoid collision between the two workpieces.

[0048] In this embodiment, in order to provide support at the bottom of the casting during the cutting process to prevent the casting from accidentally falling, Figure 7 As shown, the supporting mechanism 500 is also included, and the supporting mechanism 500 includes a moving seat 510 and a supporting seat 530; the moving seat 510 is slidably mounted on the frame 100 and connected to the feeding drive device 400, and the supporting seat 530 is slidably mounted on the moving seat 510 up and down, and the moving seat 510 is provided with a height adjustment structure 520 for adjusting the height of the supporting seat 530. The height adjustment mechanism 520 includes a screw rod 521, a connecting rod 522, a driven bevel gear 523, a driving bevel gear 524 and a hand wheel 525, the screw rod 521 is rotatably connected to the moving seat 510 through a bearing, a nut (the nut is not shown in the figure) is provided on the supporting seat 530, the nut is threadedly connected to the screw rod 521, the driven bevel gear 523 is keyed to the screw rod 521, the connecting rod 522 is rotatably connected to the moving seat 510, and is keyed to the driving bevel gear 524 and the hand wheel 525, and the driving bevel gear 524 is meshed with the driven bevel gear 523.

[0049] Of course, according to actual conditions, in some other embodiments, a hydraulic cylinder can be used to push the support seat 530 to control the height of the support seat 530. The support seat 530 is connected to the piston rod of the hydraulic cylinder, and the hydraulic cylinder pushes the piston rod so that the support seat 530 can move up and down. After the hydraulic cylinder stops moving, the support seat 530 can maintain a constant height due to the pressure-maintaining effect of the hydraulic cylinder, so that the support seat 530 can support the casting.

[0050] In this embodiment, if Figure 5 and Figure 6 As shown, the feeding drive device 400 includes a transmission chain rail 410 and a second driving mechanism 420 for driving the transmission chain rail 410 to reciprocate left and right, and the transmission chain rail 410 is connected to the automatic clamping device 300. The transmission chain rail 410 includes a first chain rail 411 and a second chain rail 412. The frame 100 is provided with a first guide rod 413 and a second guide rod 414. The automatic clamping device 300 is sleeved on the first guide rod 413. The first chain rail 411 is engaged with the automatic clamping device 300 through a chain buckle, driving the automatic clamping device 300 to slide left and right on the first guide rod 413; the moving seat 510 is sleeved on the second guide rod 414, and the second chain rail 412 is engaged with the moving seat 510 through a chain buckle, driving the moving seat 510 to slide left and right on the second guide rod 414. The second driving mechanism 420 includes a second motor 421 and a synchronization shaft 422 arranged on the frame 100. The upper and lower ends of the synchronization shaft 422 are rotationally connected to the first chain rail 411 and the second chain rail 412 through gears respectively. The second motor 421 and the synchronization shaft 422 are rotationally connected through a gear chain (the chain is not shown in the drawings).

[0051] Of course, according to actual conditions, in some other embodiments, a motor can be used to directly drive the first chain rail 411 and the second chain rail 412 to rotate through an output shaft. The motor is arranged above the first chain rail 411, and cooperates with the first chain rail 411 and the second chain rail 412 through a gear arranged on the output shaft. The output shaft rotates to drive the first chain rail 411 and the second chain rail 412 to move simultaneously.

[0052] Of course, according to actual conditions, in some other embodiments, a cylinder and a linear slide rail can be used to directly drive the automatic clamping device 300 and the movable seat 510 to slide synchronously. The automatic clamping device 300 and the movable seat 510 are slidingly connected with the linear slide rail. The cylinder drives the linear slide rails of the automatic clamping device 300 and the movable seat 510 at the same time to realize the synchronous movement of the automatic clamping device 300 and the movable seat 510.

[0053] In this embodiment, in order to facilitate the collection of waste materials removed by the movable fixture 310, as shown in FIG. Figure 8 As shown, it also includes a material dropping device 600 , which is arranged on the frame 100 and located on one side of the feeding drive device 400 .

[0054] Of course, according to actual conditions, in some other embodiments, a carton can be set on one side of the feeding drive device 400. After the automatic clamping device 300 drives the casting to complete cutting, it is located on one side of the feeding drive device 400, and the movable block 312 is released to allow the waste to fall directly into the box.

[0055] In this embodiment, in order to prevent the casting waste from being too heavy and falling into the material dropping device 600, the material dropping device 600 is damaged. Figure 8 As shown, the material dropping device 600 includes a material dropping trough 610, a buffer trough 620 and a third cylinder 630 arranged on the frame 100; the material dropping trough 610 is tilted and arranged below the buffer trough 620, the cylinder bodies of the buffer trough 620 and the third cylinder 630 are both hinged to the frame 100, and the piston rod of the third cylinder 630 is hinged to the buffer trough 620. When the movable block 312 is released, the waste falls into the buffer trough 620, and the front end of the buffer trough 620 slowly approaches the material dropping trough 610 under the buffering action of the third cylinder 630, and then the waste slides into the material dropping trough 610 under the action of gravity, completing the recycling of the waste.

[0056] Of course, according to actual conditions, in some other embodiments, a heat-resistant cotton pad can be attached to the drop chute 610, directly below the falling direction of the waste, so as to reduce the impact force of the waste falling into the drop chute 610.

[0057] The following describes in detail the working process of the efficient casting cutting machine according to this embodiment. It is worth noting that the following description is only an exemplary description and not a specific limitation of the invention.

[0058] First, the staff adjusts the height of the support seat 530 through the hand wheel 525 according to the height of the casting, so that the support seat 530 can just support the casting, and starts the first motor 222 on the processing device 200. The first motor 222 drives the saw blade 210 to rotate. At this time, the movable block 312 on the movable clamp 310 is in a loose state. The staff embeds the gate of the casting into the groove 314 of the fixed block 311, and then the piston rod of the second cylinder 313 pushes the movable block 312, so that the fixed block 311 and the movable block 312 are pressed tightly to fix the casting. The second motor 421 on the feeding drive device 400 drives the first chain rail 411 and the second chain rail 412 of the feeding drive device 400 to move simultaneously through the synchronous shaft 422. Driven by the first chain rail 411 and the second chain rail 412, the movable clamp 310 and the support mechanism 500 approach the saw blade 210 for cutting. When the movable fixture 310 and the supporting mechanism 500 move to the end of the feeding drive device 400, the piston rod of the second cylinder 313 on the movable fixture 310 retreats to release the movable block 312. After the casting waste falls into the buffer trough 620, the buffer trough 620 approaches the drop trough 610 under the buffering action of the third cylinder 630, and the casting waste slides into the drop trough 610 under the action of gravity. After the casting waste is unloaded, the second motor 421 on the feeding drive device 400 drives the movable fixture 310 and the supporting mechanism 500 to reset, and then the staff performs the next round of feeding operation.

[0059] According to the high-efficiency casting cutting machine of the embodiment of the present invention, by such a configuration, at least some of the following effects can be achieved: the pouring cup of the casting is clamped by the automatic clamping device 300, and the automatic clamping device 300 is driven by the feeding drive device 400 to approach the saw blade 210 to cut the casting. When the casting is cut, the automatic feeding device 400 drives the casting waste to the end of the machine, the automatic clamping device 300 releases the casting waste so that the waste falls into the dropping device 600, and then the automatic clamping device 300 is reset under the drive of the feeding drive device 400 to prepare for the next round of work. The staff does not need to manually clamp and disassemble the casting and other waste materials, which improves efficiency.

[0060] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
