DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described below in a clear and complete manner. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0021] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific embodiments of the present application will be described in detail below in combination with the drawings. In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0022] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0023] Example 1 The sparks and metal debris generated during the cutting operation of the casting have the risk of splashing, and the traditional isolation cover design needs to be frequently disassembled, which affects the operation efficiency. For example, although the fixed cutting chamber can isolate the splashing, it causes difficulty in daily maintenance and workpiece placement, increasing the labor intensity of the operator.

[0024] Therefore, as Figures 1-2As shown in the application, a casting cutting device is provided, which comprises a cutting bin 1, a cutting mechanism arranged on the outer wall of one side surface of the cutting bin 1, and the cutting mechanism extends to the upper side of the cutting bin 1. A cavity of the cutting bin 1 is provided with two baffles 103 which are opposite and perpendicular to the bottom of the cavity of the cutting bin 1, and a working bin is formed between the two baffles 103. The two baffles 103 are physically isolated on both sides of the working bin. The upper end of the front and rear side plates of the cutting bin 1 is continuously provided with a slide 101 from left to right. A slide hole 102 with the same length as the slide 101 is arranged on the inner side wall of the slide 101. The upper end of each of the two baffles 103 is provided with a door plate 4 which can be opened and closed and is connected between the front and rear side plates. Each of the two door plates 4 is provided with a sliding block 5 corresponding to the slide 101 on each side. The two front and rear sliding blocks 5 are connected by a clamping mechanism. The opening and closing of the door plate 4 is driven by the lifting of the cutting mechanism. In the static state, the door plate 4 is opened to facilitate maintenance and operation. In the working state, the door plate 4 is closed to effectively prevent sparks and debris from splashing. At the same time, the opening and closing of the door plate 4 and the movement of the clamping mechanism form a coordinated action. When the door plate 4 is opened and closed, the sliding block 5 moves in the slide 101. When the sliding block 5 moves along the slide, the sliding block 5 drives the clamping mechanism to adjust the position in the working bin, so as to clamp the pipe-shaped casting.

[0025] As the technical scheme of the embodiment, further, Figure 5 As shown in the application, the cutting mechanism comprises a support column 2, which is bent at the upper end and extends to the center of the working bin. The upper side of the extension end of the support column 2 is provided with a gas cylinder 3 arranged in an inverted downward manner. The extension rod 301 of the gas cylinder 3 extends downward through the support column 2 and is arranged corresponding to the upper end of the center of the working bin. Two downward fixed rods 201 are fixedly arranged at the lower side of the extension end of the support column 2. The two fixed rods 201 are arranged on the front and rear sides of the extension rod 301. When the gas cylinder 3 is started, the extension rod 301 drives the cutting tool 305 to move in the vertical direction defined by the fixed rod 201. The two fixed rods 201 are arranged on the front and rear sides of the extension rod 301 to form a symmetrical guide constraint, which ensures the verticality of the tool movement track during cutting. The bending and extension design of the support column 2 makes the installation position of the gas cylinder 3 coincide with the center axis of the working bin, avoiding the deviation of the cutting path.

[0026] As the technical scheme of the embodiment, further, Figure 5As shown, the lower end of the telescopic rod 301 is also connected with a support seat 302, the middle part of the support seat 302 protrudes with a fixed plate 303 on both sides, two fixed rods 201 are arranged in the middle part of the two fixed plates 303, the telescopic rod 301 controls the support seat 302 to move up and down on the two fixed rods 201, the middle part of the left and right sides of the support seat 302 also protrudes with a shaft seat one 304, one end of the shaft seat one 304 is connected with a shaft plate 405 which is hinged with the door plate 4, when the cylinder 3 drives the telescopic rod 301 to press down, the support seat 302 slides downward along the fixed rod 201, driving the cutting tool 305 to contact the casting for cutting. In this process, the shaft seat one 304 on both sides of the support seat 302 pulls the door plate 4 to rotate around the flat hinge shaft 401 through the shaft plate 405, so that the two door plates 4 close to the middle to form a closed working chamber. When the telescopic rod 301 retracts after cutting, the support seat 302 rises to drive the shaft plate 405 to move reversely, and the door plate 4 is opened to facilitate taking and placing the workpiece. The mechanical linkage of the support seat 302 and the door plate 4 automatically closes the working chamber during cutting, without manual intervention of the isolation device. The existing technology adopts an independent driving system for the opening and closing mechanism of the door plate 4, and the present scheme drives the door plate 4 by using the lifting movement of the cutting mechanism itself, reducing the additional power source.

[0027] As the technical scheme of the present embodiment, further, Figure 5 As shown, the lower end of the support seat 302 is provided with a clamping groove, a cutting tool 305 is rotatably installed in the clamping groove, the upper end of the clamping groove extends with a shutter on both sides, the rear end of the support seat 302 is provided with a driving motor 306, a transmission belt 307 is sleeved between the driving motor 306 and one end of the shaft of the cutting tool 305, the cutting tool 305 is rotatably installed in the bearing in the clamping groove, and the driving motor 306 drives the cutting tool 305 to rotate at high speed through the transmission belt 307 after starting. When the cylinder 3 drives the support seat 302 to move downward, the rotating cutting tool 305 contacts the casting to complete the cutting work. The shutter forms a physical barrier during the rotation of the tool, blocking the flying of metal scraps to the operating area. The rotation axis of the cutting tool 305 is coaxial with the installation position of the clamping groove, ensuring the stability of the tool running track during cutting.

[0028] As the technical scheme of the present embodiment, further, Figure 1As shown in the drawings, one of the door plates 4 is provided with a notch 404 in the middle of the end opposite to the other door plate 4, and the notch 404 is provided with a shaft seat two 403 connected with the cutting mechanism. The bottom of the door plate 4 is transversely provided with a flat opening shaft 401 which is guided on both sides and is shaft-connected in the slide one 101 on both sides of the cutting bin 1. The flat opening shaft 401 is provided with a gear 402 on the section in the slide one 101 on both sides, and the gear 402 is meshed and connected with the sliding block 5 in the slide. The door plate 4 is transversely opened and closed through the shaft connection of the flat opening shaft 401 and the slide one 101, and the cooperation of the notch 404 and the shaft seat two 403 makes the door plate 4 keep linkage with the cutting mechanism during the opening and closing process. During the cutting operation, the door plate 4 is closed to form a closed space to block the sparks and debris splashing; during the maintenance or placement of the castings, the door plate 4 is transversely opened without disassembling the isolation structure.

[0029] As the technical scheme of the embodiment, further, Figure 6 As shown in the drawings, the sliding block 5 is of a rectangular structure, and the upper end of the sliding block 5 is protrudingly provided with a tooth block 501 adapted to the gear 402. The bottom of the sliding block 5 is provided with a pulley 502. The sliding block 5 is driven by the gear 402 to move in the slide one 101 through the tooth block 501. The sliding block 5 rolls along the slide one 101 through the pulley 502 at the bottom. The gear 402 is meshed with the tooth block 501 at the upper end of the sliding block 5 when the gear 402 rotates, thereby pushing the sliding block 5 to move horizontally in the slide. When the cutting mechanism descends, the gear 402 drives the sliding block 5 to move towards the center of the working bin, so that the two door plates 4 are closed to form a closed space. After the cutting is completed, the gear 402 is reversely rotated to reset the sliding block 5, and the door plate 4 is opened to facilitate the taking and placing of the castings. The pulley 502 continuously supports the sliding block 5 during the process, thereby ensuring the stable movement and controllable resistance.

The slide two 104 is transversely provided on the opposite side of the baffle 103, and the T-shaped hole of the slide two 104 is provided with a clamping piece 701 at the bottom of the limiting rod 7. The clamping piece 701 drives the limiting rod 7 to move transversely when sliding along the T-shaped hole, and the arc-shaped clamping plate 702 at the end of the limiting rod 7 adjusts the clamping distance. The mounting hole 105 penetrates the middle of the baffle 103, the pull rod 6 passes through the mounting hole 105 and is connected with the sliding block 5. The pull rod 6 is driven by the sliding block 5 to move in the slide one 101, thereby driving the limiting rod 7 to act. When it is needed to clamp castings of different sizes, the limiting rod 7 moves transversely through the guidance of the T-shaped hole, so that the arc-shaped clamping plate 702 is attached to the surface of the castings to realize stable fixation.

When the sliding block 5 moves in the sliding way one 101, the connecting rod 503 drives the pull rod 6 to move laterally, and the positioning plate 601 pushes the limiting rod 7 to slide along the sliding way two 104. The cooperation of the clamping piece 701 and the T-shaped hole structure makes the limiting rod 7 keep a straight motion track, and the displacement of the positioning plate 601 is converted into the swinging action of the limiting rod 7 by the pull strip 8, so that the arc-shaped clamping plate 702 is attached to the surface of the casting. During the cutting process, the arc-shaped clamping plate 702 of the limiting rod 7 and the positioning plate 601 form bidirectional clamping, and the clamping stability is maintained through the restraining action of the sliding way two 104 and the clamping piece 701.
