DETAILED DESCRIPTION

[0034] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0035] Embodiment 1

[0036] like Figure 1 , Figure 2 and Figure 3As shown, a casting cutting device includes a base 1, a collecting box 5 is fixedly connected to the front end of the base 1, a shielding box 3 is fixedly connected to the upper end of the base 1, a cutting component 6 is fixedly connected to the rear part of the inner surface of the shielding box 3, a fixing structure 4 is arranged in the inner cavity of the base 1, a driving motor 2 for driving the fixing structure 4 and the cutting component 6 is fixedly connected to the left end of the base 1, the cutting component 6 is rotatably connected to the middle part of the inner surface of the shielding box 3, and the upper side of the base 1 is trapezoidal, and material conveyor belts 8 are arranged on the inclined surfaces on the left and right sides.

[0037] It should be specially noted that the above-mentioned material conveyor belt 8 is a conventional material conveying equipment, which is used to drive the material to move in the horizontal direction. In the present invention, only its characteristic of driving the material to move is utilized, and its specific application mode and operation principle are all conventional technical means. In the present invention, its specific structure and principle are not displayed and explained.

[0038] During the operation of this embodiment, the operator first uses the fixed structure 4 to fix the casting to be cut, and uses the driving motor 2 to drive the fixed structure 4 and the cutting component 6 to operate, so that each piece enters the action range of the cutting component 6 under the action of the fixed structure 4 and is cut by the cutting component 6. The cut castings will be sent to the collection box 5 through the material conveyor belt 8, and the waste after cutting will be reset under the action of the fixed structure 4. No manual intervention is required during the cutting process, which reduces the contact between the operator and the cutting equipment and reduces safety hazards. At the same time, the automatic reset effect of the fixed structure 4 can also reduce the operation process and improve the cutting efficiency.

[0039] Embodiment 2

[0040] Based on the first embodiment, the present embodiment uses the cooperation of the clamping assembly 42 and the driving assembly 43 to clamp and fix the casting by using the T-shaped slide plate 421, and then transports it inward along the track formed by the limit plates 41 on both sides, and cuts it by the cutting component 6, without the need for manual operation, reducing the number of people involved in the process, improving cutting efficiency, and reducing safety hazards.

[0041] Specifically, to achieve the function of cutting castings, refer to Figure 4 The cutting component 6 includes a central axis 61 rotatably connected to the inner surface of the shielding box 3 and a supporting wheel 64 symmetrically fixedly connected to the upper end of the base 1. The outer surface of the central axis 61 is symmetrically fixedly connected to a second driving wheel 62. The outer surfaces of the central axis 61 and the second driving wheel 62 on the same side are commonly wound with a rope saw chain 63. The central axis 61 is transmission-connected to the fixed structure 4 through a transmission belt.

[0042] The central shaft 61 rotates under the action of the transmission belt and drives the rope saw chain 63 to move through the driving wheel 2 62 and the supporting wheel 64, so that it can frictionally cut the cutting piece when it contacts with the cutting piece. Its operating principle is a mature technical means in conventional technology and will not be repeated in the present invention.

[0043] Further, in order to drive the casting to move into the shielding box 3, refer to Figure 5 The fixed structure 4 includes a limit plate 1 41 fixedly connected to the upper end of the base 1 symmetrically on the left and right, and a slide groove 2 46 fixedly connected to the inner cavity of the base 1 symmetrically on the left and right. The ends of the two limit plates 1 41 close to each other are linearly distributed and rotatably connected with a plurality of rubber wheels 45. The inner surfaces of the slide grooves 2 46 on both sides are slidably connected with clamping assemblies 42. The inner cavity of the base 1 located below the slide grooves 2 46 is provided with a driving assembly 43 for driving the clamping assembly 42, and the inner surface of the clamping assembly 42 is provided with a reset assembly 44.

[0044] A plurality of rubber wheels 45 are rotatably connected to the inner side of the limit plates 41 located on both sides of the upper end of the base 1. These rubber wheels 45 are elastic. When the casting is placed therein, the rubber wheels 45 will be squeezed to deform. However, since the rubber wheels 45 have good elasticity, when the casting moves, the rotation of the rubber wheels 45 will not be affected.

[0045] During use, the casting is first pushed between the rubber wheels 45 on both sides through the front side of the clamping assembly 42 until the casting is completely placed in the clamping assembly 42. At this time, the operation of the drive motor 2 will drive the clamping assembly 42 to move along the path formed by the limit plate 41 through the action of the drive assembly 43, and will synchronously drive the casting to move.

[0046] Further, for clamping and fixing the casting, see Figure 6 and Figure 7 The clamping assembly 42 includes two T-shaped slides 421 symmetrically distributed front and back and slidably connected to the inner surfaces of the two slide grooves 46 on both sides, the ends of the two T-shaped slides 421 close to each other are fixedly connected with a compression spring 422 through a mounting hole, and the ends of the two T-shaped slides 421 close to each other are symmetrically slidably connected to a limiting rod 423 on both sides through a limiting hole, and a slide groove 425 is provided on the side away from each other at the upper ends of the two T-shaped slides 421, and the bottom walls of the inner surfaces of the two slide grooves 425 are fixedly connected with compression springs 426, and the upper ends of the two compression springs 426 are fixedly connected with a slider 424 slidably connected to the slide groove 425 on the same side, the rear end of the T-shaped slide 421 located at the rear is fixedly connected to the reset assembly 44, and the lower end of the T-shaped slide 421 located at the front is provided with a follower component 427.

[0047] When the casting is placed in the clamping assembly 42, the front slider 424 will be pressed first to retract into the slide groove 1 425. When the rear side of the casting contacts the front end of the T-shaped slide plate 421 at the rear, the T-shaped slide plate 421 at the rear will be driven to slide backward along the slide groove 2 46. At this time, the compression spring 1 422 is extended by force until the casting is completely at the position of the sliders 424 on both sides and is clamped in the middle by the two sliders 424 under the action of the compression spring 1 422. At this time, under the action of the compression spring 1 422, the rubber wheels 45 on both sides and the slider 424, it is gradually fixed on the upper side of the two T-shaped slide plates 421. At the same time, the limiting component 7 located on the upper part of the shielding box 3 will also press the edge gradually on the upper side, so that it is fixed in the front and back, left and right and vertical directions to avoid deviation during cutting.

[0048] It should be noted that when the front T-shaped slide plate 421 is moved backward by the follower component 427, the front slider 424, the casting and the rear slider 424 will push the rear T-shaped slide plate 421 to slide synchronously;

[0049] When resetting is required, the rear T-shaped slide plate 421 will also push the front T-shaped slide plate 421 to move synchronously through the rear slider 424, the casting edge and the front slider 424.

[0050] Further, in order to follow the action of the driving assembly 43 to drive the T-shaped slide plate 421 and the casting inside thereof to move, refer to Figure 8 The follower component 427 includes a fixed block 4271 fixedly connected to the lower end of the T-shaped slide plate 421 located at the front, and the inner surface of the fixed block 4271 is symmetrically slidably connected with a limit plate 4273. The ends of the two limit plates 4273 that are far away from each other are fixedly connected with a sliding column 4272 that penetrates the inner cavity of the fixed block 4271 and extends to the outside. The ends of the two limit plates 4273 that are close to each other are commonly fixedly connected with a compression spring 4274. The rear parts of the outer surfaces of the two sliding columns 4272 are provided with wedge-shaped grooves 4275 that are connected with the front of the outer surface.

[0051] The follower component 427 is used to cooperate with the driving component 43 to drive the clamping component 42 to slide in the second slide groove 46. When the driving component 43 acts on the sliding column 4272, the T-shaped slide plate 421 at the front will be driven to move through the action of the sliding column 4272 and the fixed block 4271, thereby driving the clamping component 42 to move as a whole.

[0052] Further, in order to drive the clamping assembly 42 to move in the shielding box 3, refer to Fig. 9 , Fig.10 and Fig.11The driving assembly 43 includes tensioning wheels 431 symmetrically distributed front and back and rotatably connected to the inner surface of the base 1, the outer surfaces of the two tensioning wheels 431 are commonly wound and connected with a driving belt 432, and the outer surfaces of the driving belt 432 are symmetrically fixedly connected with a driving hook 434, the tensioning wheel 431 at the rear is fixedly connected to the output end of the driving motor 2 through a coupling, and the end of the tensioning wheel 431 at the rear away from the driving motor 2 is transmission-connected to the central shaft 61 through a transmission belt; the position of the driving hook 434 corresponds to the position of the two compression springs 4274 on the upper side, and the position of the driving hook 434 corresponds to the position of the connecting rod 444 on the lower side.

[0053] The driving belt 432 driven by the tensioning wheel 431 will drive the driving hook 434 to move on the groove track during the cyclic movement, and periodically contact the sliding column 4272. When the driving hook 434 contacts the sliding column 4272, it will push the sliding column 4272 to move backward along the sliding groove 46.

[0054] Further, in order to facilitate the disengagement of the driving hook 434 from the compression spring 4274, see Figure 6 and Fig.12 A fixing plate 428 is fixedly connected to the rear of the inner cavity of the base 1, and a ejector pin 4281 corresponding to the position of the wedge-shaped groove 4275 is fixedly connected to the front end of the fixing plate 428 symmetrically.

[0055] When the wedge-shaped groove 4275 on the sliding column 4272 contacts the ejector pin 4281, due to the wedge-shaped wedge-shaped groove 4275, the fixed block 4271 will slide inside under the action of the wedge-shaped groove 4275 and gradually disengage from the driving hook 434 until the sliding column 4272 is completely disengaged from the driving hook 434. The clamping assembly 42 will stay at the predetermined position, and the casting will be completely cut by the cutting component 6.

[0056] Embodiment 3

[0057] On the basis of the second embodiment, the present embodiment utilizes the cooperation of the connecting rod 444 and the driving hook 434 to pull the traction cable 441 around the pulley 1 442 and the pulley 2 443, and pulls the T-shaped slide 421 located at the rear to slide forward, thereby driving the clamping assembly 42 as a whole to slide forward along the second slide groove 46, so as to enable the clamping assembly 42 to carry the casting waste to reset, without manual reset, to avoid the burrs on the waste after cutting to scratch the operators, reduce safety hazards, thereby improving processing safety and avoiding affecting production efficiency.

[0058] Specifically, in order to drive the clamping assembly 42 and the casting waste therein to reset, refer to Figure 6 , Figure 7 and Fig.10The reset assembly 44 includes cables 441 symmetrically distributed on the left and right, and pulleys 1 442 and 443 respectively located at the front and rear of the inner cavity of the base 1 for tensioning the cables 441. One end of the two cables 441 is fixedly connected to the front end of the T-shaped slide 421 located at the rear. The two cables 441 are wound from top to bottom around the pulley 1 442 at the front and then from top to bottom around the pulley 2 443 at the rear, and then are fixedly connected to a connecting rod 444. A limiting groove 445 is symmetrically provided at the lower part of the inner cavity of the base 1, and the outer surface of the connecting rod 444 is slidably connected to the inner surface of the limiting groove 445.

[0059] The pulley 1 442 and the pulley 2 443 make the cable 441 present a Z-shaped track. When the T-shaped slide plate 421 at the rear moves backward, the cable 441 is pulled, and the connecting rod 444 is pulled by the cable 441 to slide backward inside the limiting groove 445.

[0060] When the T-shaped slide 421 moves to the predetermined position and the driving hook 434 disengages from the sliding column 4272, the driving hook 434 continues to operate and rotates to the lower side to overlap with the connecting rod 444 and pulls the connecting rod 444 to move forward along the limiting groove 445. At this time, the T-shaped slide 421 at the rear moves forward under the traction of the cable 441. Before the T-shaped slide 421 at the front reaches the initial position, the connecting rod 444 enters the area where the inclined track at the front of the limiting groove 445 is located and gradually slides downward until the T-shaped slide 421 reaches the initial position. At this time, the connecting rod 444 is completely disengaged from the driving hook 434, and the driving hook 434 continues to operate until it returns to the initial position.

[0061] Furthermore, in order to facilitate the connection rod 444 to be disengaged from the driving hook 434, the limiting groove 445 is L-shaped, the front side of which is a downwardly inclined trajectory and the lowermost part of the trajectory is lower than the lowest point of the driving hook 434 when it is at the lower part.

[0062] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
