Abstract
Description
Technical Field
[0001] The utility model belongs to the field of retaining frames, and in particular relates to a wind power anti-fatigue retaining frame and processing equipment thereof. Background Art
[0002] The function of the cage is to separate and fix the rollers, prevent contact between the rollers, provide lubrication space, and guide the rollers to roll, so as to minimize friction and heat generation. For wind power anti-fatigue cages, their application scenarios are usually outdoor, so the strength requirements for wind power anti-fatigue cages are also higher. When processing the cage, stamping is usually used to form the cage body into a cage, and then carry out subsequent processes. Among them, stamping refers to a pressure processing method that uses a mold installed on a press to apply pressure to the material to separate or plastically deform it, thereby obtaining the required parts.
[0003] When processing the retainer body, since it is formed into a bowl-shaped structure, there is a risk of overlapping materials and cracks after stamping, and the above-mentioned risk area is also more likely to break during subsequent use, thereby shortening the service life of the retainer. Utility Model Content
[0004] In view of the above-mentioned deficiencies, the utility model provides a wind power anti-fatigue retainer and processing equipment thereof, which can prevent the retainer body from overlapping, cracking, etc. after stamping, which affect the strength of the retainer body.
[0005] The utility model is realized by the following technical solutions:
[0006] A wind power anti-fatigue retainer, the retainer is processed from a retainer body for forming, the retainer body is stamped to form a bowl-shaped structure; the retainer body has a stamping surface and an extension surface located on the inner side, and an arc surface connecting the stamping surface and the extension surface, the retainer body abuts against a stamping component through the stamping surface to form a bowl-shaped structure through the stamping component, and the retainer body also includes a processing area extending from the center of the arc surface to both sides, the processing area is an arc structure, and the processing area is recessed at the arc surface. The processing area is formed by cutting off part of the structure at the arc surface, and the area where there will be a risk of overlapping and cracking after the retainer body is formed is cut off, so as to avoid the above-mentioned area from remaining in the retainer body, so that the overall strength of the retainer after forming is high, so that it has high bending strength and fatigue strength, and is more able to withstand impact, thereby ensuring the stability of the retainer when used outdoors.
[0007] Furthermore, a transition surface is formed at the connection between the processing area and the arc surface, so that the connection between the processing area and the arc surface is smoother, avoiding sudden steps or stress concentration steps, and after the area with the risk of overlapping materials and cracks is removed, it is also possible to avoid the area that reduces the strength of the main structure of the cage.
[0008] Furthermore, the depth of the processing area gradually decreases from the middle to the sides. The middle of the processing area is deeper, so the portion of the middle area of the retainer body that is cut off is relatively more, thereby ensuring that the area with the risk of overlapping materials and cracks is completely cut off, while the depth of the two sides of the processing area is shallower, which is convenient for the transition between the arc surfaces of the processing area, thereby facilitating the formation of a transition surface at the connection between the processing area and the arc surface.
[0009] Furthermore, the processing area is arranged symmetrically about the center point of the arc surface, so that the processing area can be located in the middle area of the arc surface, which can not only realize the removal of the area with the risk of overlapping materials and cracks, thereby avoiding excessive removal of the area, but also the removal area is concentrated in the middle position, while the two sides of the cage body are not removed, so when the cage body is assembled, the overall structural strength of the cage after assembly can also be ensured.
[0010] Furthermore, the length of the processing area is 4 to 8 mm. If the length of the processing area is too long, too much area will be cut off from the main body of the cage, which will not only cause waste but also reduce the structural strength of the main body of the cage. If the length of the processing area is too short, the area with the risk of overlapping materials and cracks will not be completely cut off, which will still cause risks.
[0011] Furthermore, the depth of the processing area is 0.1 to 0.5 mm. If the depth of the processing area is too deep, too much area will be cut off from the main body of the cage, which will also reduce the structural strength of the main body of the cage. If the depth of the processing area is too shallow, it will also lead to incomplete removal of areas with the risk of overlapping and cracking.
[0012] The present application also provides a wind power anti-fatigue retainer processing equipment for processing the above retainer, the processing equipment includes a stamping assembly for processing the retainer body and a milling assembly for processing the processing area; the stamping assembly includes a stamping frame body supporting the retainer body and a stamping die arranged at the stamping frame body, the stamping die moves toward the retainer body to form a bowl-shaped structure for the retainer body; the milling assembly includes a milling frame body supporting the retainer body and a milling cutter assembly arranged at the milling frame body, the milling cutter assembly contacts the arc surface to form a processing area. The stamping assembly can process the retainer body so that it is formed into a bowl-shaped structure, and the milling assembly can process the retainer body through the milling cutter assembly, so as to process a processing area at the retainer body to cut off the area where there is a risk of overlapping materials and cracks.
[0013] Furthermore, the stamping frame includes a first fixing plate for fixing the stamping die and a second fixing plate located on the upper side of the first fixing plate, and an elastic block is connected between the first fixing plate and the second fixing plate. The external force on the first fixing plate will be buffered by the elastic block, thereby avoiding sudden changes in the external force on the second fixing plate and the stamping die, so that the stamping of the retainer body is smoother, and the area with the risk of overlapping materials and cracks can also be reduced.
[0014] Furthermore, the stamping die includes a stamping section at the end and a connecting section connecting the stamping section and the stamping frame body, and the length of the stamping section is less than the length of the retainer body. The stamping die forms the retainer body into a bowl-shaped structure through the stamping section, and the length of the stamping section is relatively long, so that the retainer body can be covered, thereby reducing the number of stamping times for the retainer body, and also reducing the area where the risk of overlapping materials and cracks occurs.
[0015] Furthermore, the milling cutter assembly includes a milling cutter member in contact with the arc surface and a driving member arranged on the milling frame, and the milling cutter member can move in the horizontal and vertical directions from the milling frame, which can ensure that the arc surface is completely cut off to form a complete processing area, and the milling cutter member can move in the vertical direction, which can also ensure that different areas of the processing area are processed to different depths.

[0027] like Figures 1 to 5 A wind power anti-fatigue retainer shown is formed by processing a retainer body for forming, and the retainer body is stamped into a bowl-shaped structure; the retainer body has a stamping surface 11 and an extension surface 12 located on the inner side, and an arc surface 13 connecting the arc surface 13 and the extension surface 12, the retainer body abuts against the stamping component through the arc surface 13 to form a bowl-shaped structure through the stamping component, and the retainer body 1 also includes a processing area 14 extending from the center of the arc surface 13 to both sides, the processing area 14 is an arc structure, and the processing area 14 is recessed at the arc surface 13; for wind power anti-fatigue retainers, their application scenarios are usually outdoor, so the overall structure of the retainer is relatively large, and the strength requirements for wind power anti-fatigue retainers are also higher, and when processing the retainer, stamping is usually used to form the retainer body into a retainer, and subsequent processes, such as punching and other processes, are performed, so that a window hole is formed in the retainer body 1.
[0028] Among them, when the material is stamped, the material will be subjected to pressure, thereby bending and deforming, so that the retainer body 1 forms a bowl-shaped structure, and there will be a risk of overlapping and cracking at the retainer body 1 after stamping, and the risk of fracture in the area where overlapping and cracking occur is also high. Therefore, for the present application, the stamping surface 11 at the retainer is the area for stamping, and the processing area 14 is the area for further processing of the arc surface 13, and the processing area 14 is a recessed setting at the arc surface 13, so the processing area 14 is formed by cutting off part of the structure from the arc surface 13, and for the retainer body 1, the processing area 14 is formed by cutting off part of the structure at the arc surface 13, so that the area where there will be a risk of overlapping and cracking after the retainer body 1 is formed is cut off, so as to avoid the above-mentioned area remaining in the retainer body 1, so that the overall strength of the retainer body 1 after forming is high, so that it has high bending strength and fatigue strength, and can better withstand impact, thereby ensuring the stability of the retainer when used outdoors.
[0029] In the present application, the retainer body is used for processing and forming into a retainer, wherein the retainer body is a cylindrical pancake structure, that is, Figure 4 The structure shown in the figure is then formed by stamping the stamping assembly Figure 1 The bowl-shaped structure shown in the figure is further processed by punching, cutting the bottom and other subsequent processes on the basis of the bowl-shaped structure to form Figure 2 and Figure 3 The structure shown in the figure, wherein in the present application, when the processing area is processed, it is preferred that the retainer body is in Figure 1 Alternatively, the retainer body may be in the state shown in FIG. Figure 2 or Figure 3 The processing area can be processed in the state shown. Therefore, the stamping surface 11 is the area in contact with the stamping component, and the extension surface 12 is the part that rises after stamping. The connecting part between the extension surface 12 and the stamping surface 11 is the arc surface 13, and the arc surface 13 is the area where the risk of overlapping and cracking is prone to occur.
[0030] As an embodiment of the present application, a transition surface is formed at the connection between the processing area 14 and the arc surface 13; since the processing area 14 is formed by cutting out part of the structure at the arc surface 13, the transition surface is formed at the processing area 14 and the arc surface 13, so that the connection between the processing area 14 and the arc surface 13 is smoother, avoiding the occurrence of sudden steps or stress concentration steps. After the areas with the risk of overlapping materials and cracks are cut off, the re-appearance of areas that reduce the structural strength of the retaining frame body 1 can also be avoided.
[0031] As a preferred embodiment of the present application, the depth of the processing area 14 gradually decreases from the middle to both sides; for the retaining frame body 1, after stamping, the area prone to the risk of overlapping and cracking is the middle area of the retaining frame body 1. Therefore, when cutting the processing area 14, the middle part of the processing area 14 is deeper, so the part cut off from the middle area of the retaining frame body 1 is also relatively large, thereby ensuring that the area with the risk of overlapping and cracking is completely cut off, and the depth on both sides of the processing area 14 is shallow, thereby facilitating the transition between the processing area 14 and the arc surface 13, thereby facilitating the formation of a transition surface at the connection between the processing area 14 and the arc surface 13.
[0032] As an implementation mode in the present application, the processing area 14 is arranged symmetrically about the center point of the arc surface 13; thereby, the processing area 14 can be located in the middle area of the arc surface 13, so that the area with the risk of overlapping materials and cracks can be cut off, thereby avoiding excessive cutting area, and the cutting area is concentrated in the middle position, while the two side parts of the retaining frame body 1 are not cut off. Therefore, when the retaining frame body 1 is assembled, the overall structural strength of the retaining frame after assembly can also be ensured.
[0033] In the present application, the length of the processing area 14 is 4 to 8 mm, and the depth of the processing area 14 is 0.1 to 0.5 mm; if the length of the processing area 14 is too long, it will cause too much cutting area of the retaining frame body 1, which will not only cause waste, but also reduce the structural strength of the retaining frame body 1. If the length of the processing area 14 is too short, it will lead to incomplete cutting of the area with the risk of overlapping materials and cracks, and there will still be risks. Among them, since the processing area 14 is symmetrically arranged about the center point of the arc surface 13, the processing area 14 is the center of the arc surface 13 and extends equally to both sides; if the depth of the processing area 14 is too deep, it will also cause too much cutting area of the retaining frame body 1, and will also reduce the structural strength of the retaining frame body 1. If the depth of the processing area 14 is too shallow, it will also lead to incomplete cutting of the area with the risk of overlapping materials and cracks.

[0035] As an embodiment of the present application, the stamping frame includes a first fixed plate 21 for fixing the stamping die and a second fixed plate 22 located on the upper side of the first fixed plate 21, and an elastic block 23 is connected between the first fixed plate 21 and the second fixed plate 22; when the holder body 1 is stamped by the stamping die, the stamping frame will drive the stamping die to move, and by setting the first fixed plate 21 and the second fixed plate 22, the stamping die is supported by the first fixed plate 21, and the second fixed plate 22 is connected to a driving part, such as a cylinder, and an elastic block 23 is arranged between the first fixed plate 21 and the second fixed plate 22. When the second fixed plate 22 drives the stamping die to stamp the holder body 1, the force applied by the driving part to the first fixed plate 21 will be buffered by the elastic block 23, thereby avoiding sudden changes in external forces on the second fixed plate 22 and the stamping die, thereby making the stamping of the holder body 1 smoother, and also reducing the area where the risk of overlapping materials and cracks occurs.
[0036] As a preferred embodiment of the present application, the stamping die includes a stamping section 24 located at the end and a connecting section 25 connecting the stamping section 24 and the stamping frame body. The length of the stamping section 24 is less than the length of the retaining frame body 1; the stamping die uses the stamping section 24 to form the retaining frame body 1 into a bowl-shaped structure, and the length of the stamping section 24 is relatively long, so that the retaining frame body 1 can be covered, thereby reducing the number of stamping times for the retaining frame body 1, and also reducing the area where the risk of overlapping materials and cracks occurs.
[0037] As an embodiment of the present application, the milling cutter assembly 32 includes a milling cutter part in contact with the arc surface 13 and a driving part arranged on the milling frame 31, and the milling cutter part can be moved in the horizontal and vertical directions from the milling frame 31; since the processing area 14 is located at the arc surface 13 and the retaining frame body 1 is a bowl-shaped structure, the milling cutter part can be moved in the horizontal and vertical directions, which can ensure that the arc surface 13 is completely removed to form a complete processing area 14. At the same time, the milling cutter part can move in the vertical direction, and can also ensure that different areas of the processing area 14 are processed to different depths.
