[0002] New energy wind power can improve global energy shortage and environmental pollution problems. Common wind power equipment includes wind power towers, and wind power flanges are usually installed at the connection of the wind power towers. Generally, they are divided into T-shaped flanges and L-shaped flanges. The operating environment of a wind turbine generator set is harsh, and the load is complex. As the main supporting component of the wind turbine generator set, the tower supports the hub assembly, the generator, the base and other key components, and its safety is related to the safety of the whole machine operation. The tower is usually composed of multiple sections, and the flanges are connected between the sections. In order to ensure that the tower has sufficient supporting strength, the flanges connected between the sections must meet the strength requirements.

[0003] Most of the flanges used in wind turbine generator set towers are L-shaped, but in the existing device, workers often need to clamp materials back and forth between machines when producing L-shaped flanges, and then complete the production work of the flanges. This way not only wastes time and effort, but also is prone to dangerous accidents due to the high temperature on the surface of the flange. SUMMARY

At this time, the cylinder one is closed, and the protrusion two no longer moves. Then the motor two is started, and the motor two drives the ball screw to reciprocate, which can drive the silk sleeve to move up and down. Then the connecting column one can drive the protrusion one to move up and down. When the protrusion one moves up, the blank can be bent under the resistance of the upward movement of the protrusion one and the resistance of the fixed protrusion two, thereby completing the bending work of the blank. Then the bent blank can be measured for the bending angle.

[0025] In a preferred embodiment: the temperature of the carbon steel round blank after heating in the A1 step is 900-1100 DEG C, and the temperature of the austenitic stainless steel after heating in the A1 step is 1080-1150 DEG C.

[0026] In a preferred embodiment: the two said motors three are servo motors, and the first conveying roller and the third conveying roller can be driven to rotate forward and backward by the motor three.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] Please see Figures 1-7 The present invention provides a technical solution: a manufacturing process for an L-shaped flange for new energy wind power generation, comprising the following steps:

[0041] A1: Billet preparation: Select round billet carbon steel or austenitic stainless steel as raw material and heat it in a furnace;

[0042] A2: Roughening: Roughen the billet 2 obtained from heating in A1 to remove the oxide scale on the surface of billet 2;

[0043] A3: Processing: Place the blank 2 obtained by removing the oxide scale in A2 on the base 1 for processing to obtain a wind turbine flange workpiece that meets the dimensions.

[0044] The specific processing steps in step three are as follows:

[0045] Step 1: After removing the oxide scale from A2, the billet 2 is conveyed and then pressed flat.

[0046] Step 2: Bend the blank 2 that has been flattened in Step 1;

[0047] Step 3: Measure the bending angle of the blank 2 after bending in Step 2 to obtain the L-shaped flange body.

[0048] Step four: cooling and shaping the L-shaped flange body obtained in step three;

[0049] Step five: conveying the L-shaped flange body shaped in step four;

[0050] The specific steps of the down-pressing and flattening of the blank 2 after the conveying in step one are as follows:

[0051] First, the blank 2 after the removal of the oxide skin is placed on the first conveying roller 37 for conveying. When the blank 2 is conveyed to the position below the down-pressing roller 10, the cylinder two provided at the front end of the support box one 3 is started to move the down-pressing unit to the appropriate position through the recessed plate 5. At this time, the down-pressing roller 10 contacts the blank 2. Then, the motor one 12 is started, and the half gear 13 starts to rotate. The rotation of the half gear 13 drives the movable box 6 to slide left and right on the recessed plate 5 under the action of the two toothed plates one 15. With the left and right sliding of the movable box 6, the connecting plate 8 slides left and right, thereby driving the down-pressing roller 10 to down-press and flatten the blank 2 left and right. Until the blank 2 is down-pressed and flattened to the appropriate thickness, the left motor three 41 is started, and the first conveying roller 37 conveys the down-pressed and flattened blank 2 away for the bending work in step two.

[0052] The specific steps of the bending of the down-pressed and flattened blank in step two are as follows:

[0053] With the starting of the right motor three 41, the third conveying roller 39 conveys the down-pressed and flattened blank 2 to the appropriate position at the lower end of the support box two 4. First, the cylinder one 21 is started to drive the protrusion two 23 to move to the appropriate position under the action of the connecting column two 22. At this time, the cylinder one 21 is closed, and the protrusion two 23 no longer moves. Then, the motor two 16 is started to drive the ball screw 17 to reciprocate, thereby driving the silk cover 18 to move up and down, and further driving the protrusion one 20 to move up and down through the connecting column one 19. When the protrusion one 20 moves upward, the blank 2 is bent under the resistance of the upward movement of the protrusion one 20 and the resistance of the fixed protrusion two 23, thereby completing the bending of the blank 2. Then, the bent blank 2 can be measured for the subsequent bending angle.

[0054] The specific steps of the bending angle measurement of the bent blank 2 in step three are as follows:

[0055] With the bending of the blank 2, the upper end portion of the blank 2 moves against the bump three 26, with the movement of the bump three 26, the conical spring 36 is deflected at this time, facilitating the subsequent reset work of the bump three 26, and then under the action of the extension column 31, the connecting column three 32 and the limiting block 33, the limiting block 33 drives the tooth plate two 34 to move to the right, and then the tooth plate two 34 drives the meshing connecting gear 35 to rotate, so as to drive the rotating shaft two 28 to rotate, the rotation of the rotating shaft two 28 can drive the pointer 29 to rotate in the scale disc 30, and then the worker can observe the bending angle of the blank 2, so as to achieve the automatic measurement effect of the bending angle of the blank 2. When the required angle of the production workpiece is measured, the subsequent cooling and shaping work can be carried out.

[0056] The specific steps of cooling and shaping the obtained L-shaped flange body in the fourth step are as follows:

[0057] Start the fan 46 in the cooling box 44, and then concentrate the cold air generated by the fan 46 on the bent blank 2 through the pipeline 45 to complete the cooling and shaping of the blank 2, so as to obtain the L-shaped flange body.

[0058] The specific steps of conveying the shaped L-shaped flange body in the fifth step are as follows:

[0059] Start the right motor three 41, and with the start of the motor three 41, one of the third conveying rollers 39 starts to rotate, and then under the action of the sprocket two and the chain two 43 on the outer wall of the two third conveying rollers 39, the two third conveying rollers 39 rotate synchronously, and then a driving force is provided for the shaped L-shaped flange body, at this time, the plurality of fourth conveying rollers 40 also rotate with the movement of the L-shaped flange body, increasing the driving force of the L-shaped flange body movement, and then the conveying work of the L-shaped flange body is completed.

[0060] The temperature of the carbon steel round billet after heating in the A1 step is 900-1100 DEG C, and the temperature of the austenitic stainless steel after heating in the A1 step is 1080-1150 DEG C.

[0061] The two motor threes 41 are servo motors, and the first conveying roller 37 and the third conveying roller 39 can be driven to rotate forward and backward by the motor three 41.

[0062] The cooling and shaping mode of the blank 2 also includes setting a water tank for water cooling in the cooling box 44 and setting a cooler for air cooling in cooperation with the fan 46.

[0063] The working principle of the present application is as follows: Figure 1 -attached Figure 7, When the present application is used, the blank 2 to be processed, which has been decarburized and not yet cooled, is placed on the first conveying roller 37 for conveying. When the blank 2 is conveyed to below the rolling roller 10, the second air cylinder is started to move the rolling unit to the appropriate position by the recessed plate 5, at which time the rolling roller 10 contacts the blank 2. Then the first motor 12 is started to drive the movable box 6 to slide on the recessed plate 5, thereby driving the connecting plate 8 to slide, and driving the rolling roller 10 to roll on the blank 2. When the blank 2 is rolled to the appropriate thickness, it is conveyed to the third conveying roller 39 by the first conveying roller 37, and then moved to the supporting box 4 by the third conveying roller 39 for shaping. At this time, the width of the L-shaped flange body at the shaping unit is much larger than the width of the L-shaped flange body below the rolling roller before rolling. The first motor 16 drives the protrusion 20 to move upward, and the first air cylinder 21 drives the protrusion 23 to move to the left, thereby completing the shaping work of the blank 2. After the shaping is completed, the protrusion 26 is moved to the right to drive the pointer 29 to rotate in the dial 30, thereby automatically measuring the bending angle of the blank 2. When the workpiece production requirement is reached, the fan 46 is started to cool and shape, thereby obtaining the L-shaped flange body. Then the L-shaped flange body is conveyed away by the third conveying roller 39, and the whole processing work of the blank 2 is completed. Then the L-shaped flange body produced and conveyed away is welded and assembled, thereby producing the disc-shaped L-shaped flange meeting the requirement.

[0064] Finally, it should be noted that the above description is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can modify the technical solutions described in the foregoing embodiments or make equivalent replacements to some technical features. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application shall be included in the protection scope of the present application.
