Description

Technical Field

[0001] This utility model relates to the technical field of valve body casting, and in particular to a special device for removing risers in valve body casting. Background Technology

[0002] In the valve manufacturing industry, valve bodies are mostly produced using sand casting or precision casting methods. After casting, the risers and sprues connected to the valve body need to be removed.

[0003] Existing riser removal devices, such as the riser removal device disclosed in utility model patent application number 202323372256.9, mainly include a casting machine for casting wheel hubs, a cooling device for cooling wheel hubs, a cutting device for cutting the risers of wheel hubs, and a trimming device for trimming the wheel hubs after the risers are cut. In use, after the wheel hub is cast, it can be transferred multiple times through the same mechanical gripper to complete the cooling, riser removal, and trimming processes of the wheel hub.

[0004] However, most existing riser removal devices require manual confirmation and adjustment of the valve body position. During the cutting process, the valve body itself is easily damaged, affecting the product's appearance and quality. Moreover, the cut risers are scattered on the worktable, making subsequent cleaning very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a special device for cutting valve body casting risers, which not only facilitates the fixing and positioning of the valve body, ensures the cutting accuracy of the riser, and avoids affecting the product appearance and quality, but also separates and collects the cut risers, ensuring the cleanliness of the workbench.

[0006] This utility model discloses a special device for cutting risers in valve body casting, including a worktable; it also includes a moving mechanism, a fixing mechanism, a cutting mechanism, and a separating mechanism. The moving mechanism is installed on the worktable and drives the valve body to adjust its position. The fixing mechanism is installed on the moving mechanism and fixes the valve body. The cutting mechanism is installed on the worktable and cuts the riser. The separating mechanism is installed on the worktable and separates the valve body and riser for discharge. The operator places the valve body on the moving mechanism, the fixing mechanism fixes the valve body, the cutting mechanism detects the position of the valve body to ensure the cutting accuracy of the riser, and after the cutting is completed, the moving mechanism pushes the valve body forward, and the valve body and riser fall into the separating mechanism for discharge.

[0007] Preferably, the workbench includes a table body, a controller, a support grid, two sets of first electric cylinders, and two sets of guide wheels. The bottom of the table body is connected to the ground, and a groove is opened on the table body. The controller is installed on the table body, the support grid is installed in the groove of the table body, both sets of first electric cylinders are installed on the support grid, and the two sets of guide wheels are respectively installed on the two sets of first electric cylinders. The operator controls the entire cutting process through the controller. The waste generated during the cutting process falls into the separation mechanism through the support grid. The two sets of guide wheels facilitate the movement of the valve body back and forth by the moving mechanism. After the cutting is completed, the two sets of first electric cylinders drive the two sets of guide wheels to descend, which facilitates the sliding and falling of the valve body on the moving mechanism.

[0008] Preferably, the moving mechanism includes two sets of guide columns, two sets of sliders, a support plate, and a second electric cylinder. Both sets of guide columns are installed in grooves within the platform. The two sets of sliders are slidably installed on the two sets of guide columns, and the support plate is rotatably installed on the two sets of sliders. The bottom of the support plate has two sets of positioning grooves, which respectively engage with two sets of guide wheels. The second electric cylinder is installed on the platform and rotatably connected to the support plate. The controller activates the second electric cylinder via an electrical signal. The second electric cylinder drives the support plate to move back and forth, facilitating adjustment of the valve body's position. The two sets of guide columns and two sets of sliders ensure the smooth movement of the valve body. The two sets of guide wheels, in conjunction with the positioning grooves, support the support plate. After cutting is completed, the second electric cylinder pushes the support plate forward.

[0009] Preferably, the fixing mechanism includes a positioning plate, two sets of drive motors, two sets of extension rods, and two sets of fixing blocks. The bottom end of the positioning plate is connected to the top end of the support plate. Both sets of drive motors are mounted on the positioning plate. The two sets of extension rods are respectively mounted on the two sets of drive motors, and the two sets of fixing blocks are respectively mounted on the two sets of extension rods. The operator places the valve body on the guide column, with one end abutting against the positioning plate and the end with the riser hanging outside the support plate. The controller starts the two sets of drive motors, which drive the two sets of extension rods to rotate synchronously, so that the two sets of fixing blocks clamp the valve body and fix the valve body.

[0010] Preferably, the cutting mechanism includes a support frame, a detector, a hydraulic cylinder, a mounting frame, and a cutting machine. The support frame is mounted on the platform, the detector is mounted on the support frame, the hydraulic cylinder is mounted on the support frame, the top end of the mounting frame is connected to the bottom end of the hydraulic cylinder, and the cutting machine is mounted on the mounting frame. The detector detects the position of the riser, and the detection result is transmitted to the controller, which facilitates the controller to adjust the position of the moving mechanism and the valve body to ensure cutting accuracy. Then, the hydraulic cylinder is started, and the hydraulic cylinder pushes the mounting frame and the cutting machine down, and the cutting machine cuts the riser.

[0011] Preferably, the separation mechanism includes a separation plate, a collection box, a hinge, a cleaning cover, and a handle. The separation plate is installed at an angle in the groove of the platform, the collection box is installed on the platform, the hinge is installed on the collection box, the cleaning cover is installed on the hinge, and the handle is installed on the cleaning cover. Waste chips and risers generated during the cutting process fall into the collection box through the support grid and the separation plate. After the fixing mechanism is released, the valve body slides along the support plate and falls onto the separation plate, and rolls out along the separation plate.

[0012] Preferably, the upper surface of the separation plate is covered with a rubber pad; by laying the rubber pad, not only can the impact force during the valve body's fall be reduced, but the rolling speed of the valve body can also be reduced, ensuring the safe discharge of the valve body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: the operator places the valve body on the moving mechanism, the fixing mechanism fixes the valve body, the cutting mechanism detects the position of the valve body to ensure the cutting accuracy of the riser, after the cutting is completed, the moving mechanism pushes the valve body forward, and the valve body and riser fall into the separation mechanism and are discharged separately.

The top end of the mounting frame 44 is connected to the bottom end of the hydraulic cylinder 43. The cutting machine 45 is mounted on the mounting frame 44.During operation, the operator first places the valve body on the guide post 21, with one end against the positioning plate 31 and the end with the riser suspended outside the support plate 23. The controller 12 then activates two sets of drive motors 32, which in turn drive two sets of extension rods 33 to rotate synchronously, causing two sets of fixing blocks 34 to clamp and secure the valve body. The detector 42 detects the position of the riser, and the detection result is sent to the controller 12. The controller 12 then activates the second electric cylinder 24 via an electrical signal, causing the support plate 23 to move back and forth.
