Description

Technical Field

[0001] This utility model relates to the field of casting gate cutting technology, specifically a cutting device for casting gates. Background Technology

[0002] After sand casting is completed, the surface of the workpiece will have residual material from the gate, which needs to be removed with the help of special cutting equipment to meet the requirements of subsequent processing and use.

[0003] A casting gate cutting device, as described in application number CN202422828446.5, includes a base plate with a collection box for collecting the casting gates. A mounting plate has first sliding grooves extending vertically through its sides, and a clamping plate for holding the casting is slidably disposed within these grooves. A bracket is fixedly mounted on the upper part of the mounting plate, and a cutting mechanism for cutting the casting gates is mounted on the upper part of the bracket. This invention uses multiple first electric telescopic rods to simultaneously push a push plate, gradually reducing the gaps between multiple castings placed on the mounting plate and ensuring the castings are centered on the positioning plate. Furthermore, when the clamping plate is moved by second electric telescopic rods, the ends of multiple casting gates are in contact with the positioning plate, preventing uneven cutting and facilitating simultaneous cutting of multiple castings, thus improving cutting efficiency.

[0004] Currently, most existing casting gate cutting devices have a fixed overall structure, making it impossible to adjust the height and position of the workpiece and difficult to adapt to various castings with different gate heights. Furthermore, these devices have a single clamping structure, suitable only for small castings with regular shapes and uniform dimensions, and cannot reliably clamp sand castings with different cross-sections.

[0005] To address the above problems, a cutting device for the gate of castings is proposed. Utility Model Content

A collection box 10 is provided below the guide plate 9.

[0027] Please see Figure 3A lifting assembly 4 for driving the slide 3 to rise and slide is provided between the base frame 1 and the slide 3. The lifting assembly 4 includes a fixed seat 41 fixed on the base frame 1. Fixed rods 42 are fixedly installed on both the fixed seat 41 and the slide 3. Through slots 45 are opened on both sides of the fixed seat 41 and the slide 3. A slide rod 44 is slidably assembled in the through slot 45. A hydraulic rod 43 is hinged between the slide rod 44 and the fixed rod 42. The hydraulic rod 43 is electrically connected to the controller 11. A scissor bar 46 is hinged between the fixed rod 42 of the slide 3 and the slide rod 44 on the fixed seat 41. A scissor bar 47 is hinged between the slide rod 44 of the slide 3 and the fixed rod 42 on the fixed seat 41. The scissor bar 46 and the scissor bar 47 intersect each other and are hinged together.

[0028] Please see Figure 1 The drive assembly 7 includes a motor 71 fixedly mounted on the side wall of the slide 3. The motor 71 is electrically connected to the controller 11. A lead screw 72 is fixedly connected to the output end of the motor 71. The slide 6 is threadedly engaged with the lead screw 72, and the lead screw 72 is rotatably engaged with the slide 3.

[0029] Please see Figure 2 The clamping assembly 8 includes a fixed support plate 81 fixed to one side of the sliding seat 6, a vertical plate 83 fixedly installed on the other side of the sliding seat 6, a screw 84 threaded on the internal thread of the vertical plate 83, a handwheel 85 fixedly installed at one end of the screw 84, and a movable support plate 86 rotatably connected to the other end of the screw 84. A limit groove 82 is provided on the sliding seat 6, and a limit block 88 that slides in cooperation with the limit groove 82 is fixed at the bottom of the movable support plate 86.

[0030] Please see Figure 2 and Figure 4 Both the fixed support plate 81 and the movable support plate 86 have several clamping parts 87 on their inner walls. Each clamping part 87 includes a telescopic rod 871 fixed to the inner wall of the fixed support plate 81 or the movable support plate 86. A clamping ball 873 is fixedly installed at the end of the telescopic rod 871. A spring 872 is sleeved on the outer ring of the telescopic rod 871. One end of the spring 872 on the fixed support plate 81 is fixedly connected to the fixed support plate 81, and one end of the spring 872 on the movable support plate 86 is fixedly connected to the movable support plate 86. The other end of the spring 872 is fixedly connected to the clamping ball 873.

[0031] In this embodiment: First, the equipment is powered on and debugged. The controller 11 detects the operating status of the hydraulic rod 43, motor 1 71, and motor 2 14 to ensure that the transmission structure and hinge structure slide smoothly without jamming or interference, and to ensure that the equipment as a whole is in a normal standby working state.

[0032] Subsequently, the workpiece clamping operation is carried out. The casting to be cut into the gate is placed between the fixed support plate 81 and the movable support plate 86 of the sliding seat 6. According to the outer size and cross-sectional specifications of the casting, the handwheel 85 is manually turned. The handwheel 85 drives the screw 84 to rotate. The screw 84 pushes the movable support plate 86 to move. The limiting block 88 at the bottom of the movable support plate 86 slides precisely along the limiting groove 82 of the sliding seat 6, effectively limiting the offset and sway of the movable support plate 86, and stably adjusting the distance between the fixed support plate 81 and the movable support plate 86 to adapt to the placement requirements of round castings with different outer diameters and rectangular castings with different side lengths.

[0033] After the clamping balls 873 of the two clamping parts 87 are in contact with the outer wall of the casting, the handwheel 85 is rotated slightly to complete the clamping operation. The clamping balls 873 are subjected to the reverse squeezing force of the casting, which drives the telescopic rod 871 to retract. At the same time, it compresses the spring 872 sleeved on the outside. The elastic deformation of the spring 872 forms a flexible clamping force, which can not only tightly fit the rough and irregular outer surface of the sand casting, achieving gapless fitting and fixing, and eliminating the problems of casting shaking, displacement and rotation during the cutting process, but also avoid the surface of the casting being bumped or damaged due to excessive rigid clamping pressure, effectively protecting the integrity of the casting body.

[0034] After the workpiece is clamped, the height alignment adjustment is performed. According to the actual height of the casting gate, the hydraulic rod 43 is controlled to extend and retract by the controller 11. The hydraulic rod 43 pushes and pulls the corresponding slide rod 44, so that the slide rod 44 on the fixed seat 41 and the slide seat 3 slide horizontally in the corresponding through groove 45.

[0035] One end of scissor bar 46 and scissor bar 47 are hinged to the fixed rod 42 on the fixed seat 41 and the slide 3, respectively. This connection position only allows for fixed-point rotation. The other end of scissor bar 46 and scissor bar 47 are hinged to the corresponding slide rod 44, allowing them to slide synchronously with the slide rod 44. Relying on the cooperative structure of sliding at both ends and fixed-point rotation at both ends, the cross-hinged scissor bar 46 and scissor bar 47 continuously undergo angular opening and closing deformation, thereby driving the slide 3 to rise and fall vertically along the column 2, synchronously adjusting the overall height of the upper slide seat 6 and the fixed casting, so that the gate of the casting is aligned with the fixedly installed cutting saw blade 17, completing the automated tool setting operation. This effectively solves the problems of traditional equipment being unable to adapt to castings with different gate heights, and easily causing cutting deviation, gate residue, and uneven cut surfaces, thus adapting to the processing needs of castings of various specifications.

[0036] Once alignment is complete, cutting can begin. Then, controller 11 starts motor 2 14, which drives transmission shaft 15 to rotate continuously and at a constant speed, causing the cutting saw blade 17 to operate at high speed and stably. A protective cover 16 covers the entire cutting saw blade 17, effectively preventing metal chips and debris from flying during cutting, protecting the working environment and personnel safety. Next, controller 11 starts motor 1 71, which drives lead screw 72 to rotate continuously. Lead screw 72, through threaded transmission, drives sliding seat 6 to smoothly and horizontally feed along the slide rail 5 at the top of sliding seat 3, allowing the clamped casting to slowly approach the high-speed rotating cutting saw blade 17. Through the horizontal movement of the casting and the fixed cutting of the saw blade, the casting gate is smoothly and flush with the cut surface, resulting in uniform and stable cutting force, effectively improving the flatness of the cut surface and reducing subsequent grinding processes.

[0037] The gate residue, iron filings, and dust generated during the cutting process will automatically slide down the guide plate 9 on the side of the slide block 3 and be collected in the collection box 10 below the guide plate 9. This achieves centralized collection and treatment of waste materials, avoids the accumulation of debris inside the equipment from affecting the structural operation, and keeps the working environment clean.

[0038] After a single cutting operation is completed, the control motor 71 reverses its rotation, driving the sliding seat 6 and the casting to reset. After the cutting saw blade 17 stops completely, the handwheel 85 is rotated in the reverse direction to release the movable support plate 86, releasing the clamping and fixing of the casting. The finished casting can then be removed, and the next workpiece can be cut in a cycle. The overall operation is convenient, stable, and has a wide range of applications, effectively improving the processing efficiency and quality of casting gate cutting.

[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
