Problems solved by technology

[0002] The wind power door frame flange is forged on a large hydraulic press, then the ring is rolled by a ring rolling machine, and finally the circular door frame is pressed into an ellipse by a hydraulic press. Ring-shaped mechanical parts with a rectangular geometric size and weight are all made of forgings made by free forging through machining and other processes. Although the dimensions of the mechanical parts are all qualified, there are still deficiencies. The reason is that its service life is reduced due to the fiber discontinuity inside the metal of the elliptical mechanical parts, and the product qualification rate is low, the production efficiency is low, and the production cost is high. At present, when the door frame flange is produced and forged, the blank material is limited. The position is fixed, it is inconvenient to adjust the thickness of the door frame flange, so that the production is single, in view of this, we propose a wind power tower with a multi-stage heating section for the production equipment of the door frame flange

Embodiment 1

[0042] see Figure 1-Figure 6As shown, this embodiment provides a door frame flange production equipment for wind power towers equipped with multi-stage heating sections, at least including:

[0043] The multi-stage heating mechanism 100, the multi-stage heating mechanism 100 includes three heating boxes 110, the opening of the outer wall of the heating box 110 is hinged with a sealed door 111, through the sealed door 111 it is convenient to take and place the blank, the three heating boxes 110 are connected internally, and the heating box The outer wall of 110 is connected with a coal-fired heater 120, and when the billet is placed inside the heating box 110, the coal in the coal-fired heater 120 is burned to generate heat, so that the heat is diffused inside the heating box 110 to ensure structural integrity. 110 is provided with a fixed frame 112 in the inner cavity near the bottom, and two symmetrical control gates 113 are arranged for rotation inside the fixed frame 112. ...

Embodiment 2

[0050] In order to avoid hitting the inner wall of the forging box 200, which is beneficial to improve the service life of the forging box 200, the difference between this embodiment and the embodiment 1 is that please refer to 7, wherein:

[0051] A buffer spring 222 is fixedly connected between the beating plate 221 and the inner wall of the forging box 200. Through the buffer spring 222, when the beating plate 221 moves with the output rod of the hydraulic machine 220, it can be performed when the beating plate 221 is close to the inner wall of the forging box 200. Buffering, to avoid hitting the inner wall of the forging box 200, which is beneficial to improve the service life of the forging box 200, the buffer spring 222 is provided with a fixed rod 2221, the end of the fixed rod 2221 is fixedly connected to the inner wall of the forging box 200, and the inside of the fixed rod 2221 is slidingly provided with The piston rod 2222, the end of the piston rod 2222 slides out o...

Embodiment 3

[0053] For the convenience of taking out the forged piece after forging, the difference between this embodiment and Embodiment 1 is that please refer to Figure 8-Figure 9 shown, where:

[0054] There is a groove 230 at the bottom of the inner cavity of the forging box 200, and a plurality of transmission rollers 231 are arranged in rotation inside the groove 230. The outer wall of the transmission roller 231 is closely attached to the bottom of the support plate 210, so that after the forging is completed, the plurality of transmission rollers 231 When rotating at the same time, the conveying roller 231 rolls along the bottom of the support plate 210, driving the support plate 210 to slide out of the forging box 200, which is convenient for taking out the forging after the forging is finished, and is more practical.

[0055] Specifically, the ends of the transmission rollers 231 rotate and extend into the inner layer of the forging box 200 to be fixedly connected with a drive...

Abstract

The invention relates to the technical field of door frame flange production, and particularly relates to a door frame flange production device provided with a multi-stage heating section and used for a wind power tower. The door frame flange production device at least comprises a multi-stage heating mechanism and a forging box; the multi-stage heating mechanism comprises three heating boxes; sealing doors are hinged to openings of the outer walls of the heating boxes; the interiors of the three heating boxes communicate with one another; the outer walls of the heating boxes communicate with coal-fired heaters; a fixing frame is arranged in an inner cavity, close to the bottom, of each heating box; two symmetrical adjusting and controlling doors are rotationally arranged in each fixing frame; a supporting plate is slidably arranged at the bottom of an inner cavity of the forging box; oil presses are embedded in the inner walls of the two sides of the forging box; the ends of output rods of the oil presses are fixedly connected with striking plates; and the striking plates are located at the top of the supporting plate. According to the door frame flange production device, multi-stage heating forging can be achieved, metal fibers of a forged piece are continuous, the production quality of a door frame flange is improved, and the production thickness of the door frame flange can be rotationally adjusted.
