Description

Technical Field

[0001] This utility model relates to the technical field of check valve manufacturing, and in particular to a punching device for a circular check valve. Background Technology

[0002] Circular check valves are a common type of valve used in industrial pipelines. Their valve bodies are usually circular, and during the valve manufacturing process, the valve flanges need to be punched.

[0003] Existing circular check valve punching devices, such as the valve punching device disclosed in utility model patent application number 202420219891.9, mainly include a processing machine body, a support frame fixedly connected inside the processing machine body, a drive motor installed at the bottom of the support frame, and a rotating shaft fixedly connected to the output end of the drive motor. A rotating disk is rotatably connected inside the processing machine body, and the rotating disk is positioned at the top of the corresponding support frame. In use, by rotating the adjusting screw, the adjusting screw engages with the threaded part of the second support plate, pushing the extrusion block downward to fix the valve and flange placed on the top of the rotating disk.

[0004] However, multiple through holes need to be punched on the flange. Existing punching equipment requires adjustment of the flange each time, which is very troublesome and makes continuous punching difficult. Moreover, punching easily produces burrs, which require manual secondary grinding, which is also very troublesome. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a round check valve punching device that can not only continuously punch the check valve, eliminating the trouble of manually adjusting the position of the check valve and improving work efficiency, but also grind the through hole after punching to remove the burrs generated by punching.

[0006] This utility model discloses a punching device for a circular check valve, including a worktable; it also includes a fixing mechanism, a rotating mechanism, an adjusting mechanism, a punching mechanism, a grinding mechanism, and a collecting mechanism. The fixing mechanism is installed on the worktable and fixes the valve body; the rotating mechanism is installed on the worktable and facilitates multiple punching operations; the adjusting mechanism is installed on the rotating mechanism and adjusts the punching position; the punching mechanism is installed on the adjusting mechanism and punches the flange; the grinding mechanism is installed on the adjusting mechanism and grinds the through hole; and the collecting mechanism is installed on the worktable and collects the waste. The operator places the circular check valve on the fixing mechanism, which fixes the flange. The operator adjusts the positions of the punching and grinding mechanisms using the adjusting mechanism to facilitate punching position adjustment. Then, the punching mechanism is started to punch the flange. The rotating mechanism then rotates the punching mechanism to facilitate further punching operations. After punching, the grinding mechanism grinds the through hole. The waste generated during punching and grinding falls into the collecting mechanism for collection.
