Description

Technical Field

[0001] The utility model relates to the technical field of spiral metal streamline structure valve production, in particular to a forming device for spiral metal streamline structure valve production. Background Technique

[0002] After more than a hundred years of development, the engine has become an extremely widespread power machine. As a key basic part for sealing the intake and exhaust ports during the operation of the engine, the valve is used to block the air flow passage and control the gas exchange of the engine. Therefore, it has been widely studied. With the progress of technology, due to the valve being under working conditions such as high temperature, high pressure, impact load, and corrosion, and at the same time meeting factors such as high reliability, long life, and good economy of the valve, the valve is made of metal materials, and the valve materials have also changed from the initial ordinary alloy steel to the current heat-resistant steel, superalloy, titanium alloy and other materials.

[0003] More specifically, during the forming process of the valve blank, spiral metal streamlines will be formed on the surface of the valve product. The direction of these metal streamlines is consistent with the valve shape to improve the tensile strength and yield strength of the valve. For the forming of the spiral metal streamlines on the valve surface, usually a cutting tool is used to continuously adjust its position and then engrave the spiral metal streamlines one by one. However, such an operation requires continuous adjustment of the cutting tool, resulting in an overly complex operation of the cutting tool and thus reducing the forming efficiency. For this reason, we have proposed a forming device for spiral metal streamline structure valve production. Content of the Utility Model

The top end of the valve abuts against a rotatable threaded rod. A linkage collar is threadedly sleeved on the outer side of the threaded rod. A connecting rod is fixedly connected to the outer side of the linkage collar. The outer end of the connecting rod is fixedly connected to a vertically moving movable ring plate. An extension rod is fixedly connected to the bottom of the movable ring plate. A square rod engraving tool that can contact the outer side of the valve is movably connected inside the extension rod.

[0006] Optionally, the limiting seat is movably sleeved on the base, and the bottom end of the valve is in a semi-encapsulated state inside the limiting seat.

[0007] Optionally, a fixed column is fixedly connected to the top of the base, the top end of the fixed column is fixedly connected to a top plate, and a center of the bottom of the top plate is fixedly connected to an electric push rod, and a bottom end of the electric push rod is fixedly connected to a connection base.

[0008] Optionally, a plurality of positioning sliding rods are fixedly connected to the bottom of the connection base, and the positioning sliding rods are jointly movably connected to the moving ring plate, and a top end of the threaded rod is fixedly connected to a driving wheel.

[0009] Optionally, the driving wheel is movably sleeved inside the connection base, and a first motor is fixedly connected inside the connection base, and an output shaft of the first motor is connected to the driving wheel.

[0011] The present utility model has the following beneficial effects:

[0012] 1.
