Description

Technical Field

[0001] The utility model relates to the technical field of processing steam turbine bolts, in particular to a processing device for steam turbine bolts. Background Art

[0002] Steam turbine bolts are usually used to connect various parts of steam turbines, such as blades, impellers, etc. These bolts need to be strictly designed, manufactured and installed to ensure the smooth operation and safety performance of the steam turbine. During the manufacturing process, steam turbine bolts may need to undergo processes such as heat treatment and surface treatment to improve their hardness, strength and corrosion resistance.

[0003] A bolt processing die disclosed in publication number CN211360321U, during the one-punch and four-punch processing of this scheme, the fine punching upper die, fine punching lower die, and needle punch rod are all universal, which saves die cost and improves work efficiency.

[0004] However, this bolt processing die has the following disadvantages:

[0005] When die-casting bolts, the bolts need to be heated to red before die-casting to improve their ability to deform. After die-casting is completed, the heat still exists, which will cause defects and deformation of the bolts.

[0006] When die-casting bolts, a large amount of iron filings will be generated at the die-casting position, and the presence of iron filings will affect the forming of the next bolt die-casting.

[0007] In view of this, the present utility model is proposed. Utility Model Content

[0008] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a processing device for turbine bolts, thereby solving the problems raised in the above-mentioned background technology.

[0009] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is:

[0010] A processing device for turbine bolts comprises a base plate, a mold cylinder matched with the bolt column is fixedly connected to the middle of the top of the base plate, a support plate is fixedly connected to the side of the base plate, a slide groove is provided on the surface of the support plate, a cleaning component for cleaning debris generated by bolt processing is slidably connected inside the slide groove, a hydraulic rod for die-casting is arranged on one side of the top of the support plate, and a cooling component for accelerating the cooling of the bolt is arranged at the bottom end of the hydraulic rod.

[0011] Optionally, the cleaning component includes a slider slidably connected to the inside of a slide groove, a positioning plate is provided on one side of the slider, a flexible brush is provided at the bottom of the positioning plate, the height of the slide groove is slightly lower than the height of the mold block, and the bottom of the flexible brush is in contact with the top of the mold block.

[0012] Optionally, the cooling component includes a die-cast block arranged at the bottom end of the hydraulic rod, a cavity is opened on one side of the bottom of the die-cast block, a semiconductor refrigeration plate is arranged on the bottom surface of the inner wall of the cavity, the cooling end of the semiconductor refrigeration plate is in contact with the inner bottom of the cavity, the surface of the semiconductor refrigeration plate is electrically connected to the temperature controller, and the surface of the temperature controller is electrically connected to the battery.

[0013] Optionally, a mold block is provided at the top of the mold cylinder, and an inner octagonal groove for die-casting of bolts is opened on the top of the mold block. The design of the inner octagonal groove can die-cast the top of the bolt into an octagonal shape.

[0014] Optionally, a support frame is fixedly connected to the side of the mold block, and the bottom of the support frame is fixedly connected to one side of the top of the base plate. The design of the support frame improves the stability of the mold block and improves its bearing capacity during die-casting.

[0015] Optionally, a heat dissipation hole is opened on the side of the die-cast block, and the heat dissipation hole is interconnected with the interior of the cavity. The design of the heat dissipation hole can dissipate the heat generated by the heating end of the semiconductor refrigeration plate because the heat dissipation hole is interconnected with the interior of the cavity, thereby improving the cooling effect of the semiconductor refrigeration plate.

[0016] 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:

[0017] 1. The processing device for turbine bolts, through the setting of the cooling component, turns on the temperature controller in advance during the bolt processing die-casting, so that the battery and the semiconductor refrigeration sheet are energized, and the temperature controller is used to adjust the refrigeration temperature of the semiconductor refrigeration sheet to a suitable temperature. Since the refrigeration end of the semiconductor refrigeration sheet is attached to the inner bottom surface of the cavity, and then with the continuous cooling of the semiconductor refrigeration sheet, the bottom surface of the die-casting block can generate a low temperature. At this time, the red-hot bolts are placed inside the inner octagonal groove, and the hydraulic rod is started, so that the hydraulic rod drives the die-casting block to move downward until it is die-cast to the surface of the mold block, and the bolts in the inner octagonal groove are die-cast. During the die-casting process, the red-hot bolts can be quickly cooled down due to the influence of the low temperature, thereby avoiding defects and deformation, so as to ensure the quality and performance of the bolts.

[0018] 2. The processing device for turbine bolts is provided with a cleaning component. When the die-casting is completed, the hydraulic rod drives the die-casting block to rise. At this time, the staff can reciprocate the slider, so that the slider drives the positioning plate and the flexible plate brush to start cleaning the surface of the mold block and remove the iron filings on the surface of the mold block, thereby ensuring the smooth progress of the next die-casting, thereby improving the success rate during the die-casting period.
