Description

Technical Field

[0001] The utility model belongs to the field of square hole processing of a forged steel valve body, and specifically relates to a square hole processing device of a forged steel valve body. Background Art

[0002] In the prior art of processing the square hole of a valve body, a certain amount of dust remains on the surface of the valve body during processing, which affects the accuracy of the square hole processing. At the same time, when processing the square hole of the valve body, there is a lack of fixation of the valve body, and since the surface of the valve body is relatively smooth, it causes deviation during fixation.

[0003] A Chinese patent with publication number CN211564182U discloses a square hole processing device for a forged steel valve body, including a positioning ring coaxial with the guide hole at the top of a guide seat, the positioning ring can facilitate the positioning of the valve body on the workbench, so that the position of the square hole processed by the valve body corresponds to the position of the square knife; the slide bar in the pre-positioning mechanism can be pressed against the valve body with the help of a positioning plate under the action of a compression spring, and the direction of the valve body can be positioned to ensure that the square knife can process a qualified square hole on the valve body; the pressure of the compression spring on the slide bar can be adjusted by rotating the plug, and the square knife can be driven upward by a hydraulic cylinder to process a square hole on the valve body at one time, thereby improving processing efficiency and accelerating production. Moreover, since the square hole is formed by a square knife at one time, the inner wall of the square hole will be smoother than that processed by the traditional method.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0012] Optionally, support rods are provided at the four corners of the bottom of the base, and gaskets are provided at the bottom of the support rods.

[0013] After adopting the above technical solution, the utility model has the following beneficial effects compared with the prior art. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described below at the same time:

[0014] 1. Through the setting of the cleaning component and the positioning component, when processing the square hole of the forged steel valve body, the valve body is placed on the top of the fixed block, so that the two sides of the valve body are located between the U-shaped frames, and the threaded bolt is turned to make the threaded bolt drive the positioning plate to move until the serrated plate fits the surface of the valve body. The serrated setting of the serrated plate can increase a certain friction force to avoid displacement of the valve body between the positioning plates, thereby improving the stability of the fixed valve body. After the valve body is fixed, the push handle can be moved horizontally, so that the push handle drives the slider to move horizontally inside the slide groove, and then drives the flexible long brush to clean the surface of the valve body, remove the dust on the surface, ensure the subsequent square hole processing, improve the accuracy of square hole processing, and avoid dust entering the inside of the valve body when the square hole is punched.
