Description

Technical Field

[0001] The invention relates to the technical field of steam sealing piece processing equipment, and in particular to a steam sealing piece forming device. Background Art

[0002] Steam seals are key components used in rotating machinery such as steam turbines to reduce or prevent steam or gas leakage. Steam seals are usually composed of multiple spaced metal sheets with different shapes but all parallel to the axis of the turbine. When steam flows from the high-pressure steam area to the low-pressure air area, the steam moves along the axis of the turbine because its density is smaller than that of air. The steam seal plays a role in this process, blocking the metal sheet and changing the direction of steam movement, reducing the speed of the steam and ultimately achieving a sealing effect. At the same time, the spacing design of the metal sheet will also produce a certain amount of eddy current, which helps to reduce steam leakage.

[0003] The general production method of steam seals is: first draw the corresponding arc pattern of the steam seal on the steel plate according to the design requirements, then cut it according to the drawing by a cutting method, and then use other bending and planing machines to complete the processing steps. Therefore, it is easy to waste a lot of time when transferring to other processes for processing again, which leads to a decrease in its production efficiency.

The two limit rods are used to limit the two sides of the steam sealing piece workpiece, and then the first drive motor is started intermittently. The output end of the first drive motor drives the drive shaft to rotate, and then the drive gear drives the chain to rotate, so that the steam sealing piece workpiece is pushed through the auxiliary frame to intermittently feed to the bottom of the cutting tool, and then the cutting tool is started, and the surface of the steam sealing piece workpiece is cut by the cutting tool.

[0018] 4. By setting a lock, when the sliding rod pushes the second spur rack to move upward to the maximum distance, the pin is aligned with the fixing hole, and the connecting spring pushes the pin into the fixing hole, thereby fixing the sliding rod, so that the pressure plate can continue to press on the top of the steam sealing piece workpiece during the flipping process of the steam sealing piece workpiece, thereby ensuring the normal operation of the device.

[0036] When the steam sealing piece workpiece 11 is cut by the cutting tool 8 and then continues to move forward under the drive of the chain 3, the first spherical rod 29 will contact the inclined surface of one side of the first trapezoidal block 16, and the sliding rod 36 will be pushed by the first trapezoidal block 16 to drive the second spur rack 38 to move upward, thereby driving the second spur gear 39 to drive the pressing plate 50 to rotate toward the top of the steam sealing piece workpiece 11 through the rotating shaft 27.
