Description

Technical Field

[0001] The utility model belongs to the field of retainer processing, and in particular relates to a sway feeding device for processing a tapered bearing retainer. Background Art

[0002] In the processing of tapered bearing retainers, the material strip is continuously punched while being moved, and the material strip moves in a straight line during punching, so that a plurality of discs are punched out of the material strip. The discs can be formed into tapered bearing retainers through subsequent processing such as bottom cutting and punching. When punching the material strip, the discs are cut off from the material strip, and the material strip is usually a square, while the punched discs are cylindrical. Therefore, a large amount of waste is generated during the stamping process, i.e., the surrounding areas of the punched discs. Since the above-mentioned areas can no longer meet the area required by another disc, they cannot be processed further, thus forming waste. Utility Model Content

[0003] In view of the above-mentioned deficiencies, the utility model provides an eccentric feeding device for processing a tapered bearing retainer, which changes the arrangement of the punching holes in the material strip by synchronously eccentricating the material strip when punching the material strip, thereby improving the utilization rate of the material strip.

[0004] The utility model is realized by the following technical solutions:

[0005] A skew feeding device for processing a tapered bearing retainer, the skew feeding device includes a feeding unit for conveying a material belt and a punching unit for forming punching holes on the material belt; the feeding unit includes a feeding channel for moving the material belt and a skew assembly arranged at the moving path of the material belt, the skew assembly includes a clamping member and a skew member located on one side of the clamping member, the skew member can drive the material belt to move in a direction perpendicular to the moving direction of the material belt, the clamping member includes a first clamping plate for carrying the material belt and a second clamping plate located on the upper side of the first clamping plate; the punching unit includes a punching member located on the upper side of the feeding channel, the material belt is sequentially formed with a plurality of punching holes by the punching member, and the center of each punching hole is located on one side of the center line of the material belt; wherein, when the skew member drives the material belt to move, a moving gap is formed between the first clamping plate and the second clamping plate, and when the punching member moves toward the material belt, the first clamping plate and the second clamping plate clamp the material belt therebetween. By making the material strip deflect simultaneously during the movement, the line connecting the centers of the two punching holes is inclined, and the spacing between the two punching holes along the moving direction of the material strip will be reduced accordingly. The number of punching holes formed by the material strip of the same length will also be greater, thereby improving the utilization rate of the material strip and reducing production costs.

[0006] Furthermore, the stamping unit further includes a frame supporting the stamping part and a stopper fixed to the frame, and the stopper is formed with a through hole located at the lower side of the stamping part. The frame plays a supporting role, and the stopper is located at the lower side of the stamping part, so the stopper can carry the material strip, so as to play a role of supporting the material strip when the stamping part is stamped, and the through hole formed at the stopper corresponds to the stamping part, so the stamping part can extend into the through hole to pass through the material strip, thereby realizing the formation of the stamping hole.

[0007] Furthermore, the stamping unit further includes an air blowing member disposed on one side of the limiting member, and the air blowing member is located at the upper end surface of the stamping hole. When the stamping member is separated from the stamping hole, the disc brought out at this time will correspond to the air blowing member, and gas will be generated at the air blowing member, thereby blowing the stamped disc, so that the disc is separated from the stamping member, which does not affect the stamping of the material strip again by the stamping member, and also facilitates the recovery of the disc.

[0008] Furthermore, the stamping unit further comprises a recovery part arranged opposite to the air-blowing part, the recovery part and the air-blowing part are respectively located on both sides of the limiting part, and the height of the recovery part gradually increases in the direction away from the air-blowing part. Since the air-blowing part moves the disc formed after stamping in the direction away from the air-blowing part when blowing, the recovery part and the air-blowing part are arranged opposite to each other and are respectively located on both sides of the limiting part, so that the disc blown out by the air-blowing part can smoothly enter the recovery part, and the height of the recovery part gradually increases in the direction away from the air-blowing part, which can not only block the disc through the high point at the far end to prevent the disc from passing over the recovery part, but also ensure that the disc can smoothly enter the recovery part at the low point at the near end.

[0009] Furthermore, the limiting member also includes a positioning column arranged in the punching hole, the positioning column is arranged coaxially with the through hole, and the positioning column can reciprocate along the axial direction of the punching hole. Since the punching member can extend into the through hole, thereby passing through the material strip, so as to form a through punching hole at the material strip, and while the punching hole is formed, the disc will also be separated from the material strip accordingly, so by setting the positioning column, the separated disc can fall on the positioning column, thereby preventing the disc from falling into the through hole, and the positioning column can reciprocate along the axial direction of the punching hole, so when the punching member moves in a direction away from the through hole, the positioning column can also move in the same direction, so that the disc can be exposed from the through hole, and under the drive of the punching member, it moves to correspond to the air blowing member, so that it is blown into the recovery member by the air blowing member for recovery.

[0010] Furthermore, the limiting member includes a first limiting plate for carrying the material strip and a second limiting plate located on the upper side of the first limiting plate, the punching hole is formed at the second limiting plate, and the material strip moves between the first limiting plate and the second limiting plate. The first limiting plate and the second limiting plate can also ensure that the material strip is in a flush state when punching the material strip, and the position of the punching hole formed is more accurate, avoiding interference with other punching holes, thereby ensuring the quality of the processed wafer.

[0011] Furthermore, the spacing between two punching holes formed in sequence at the material strip by the punching part along the moving direction of the material strip is smaller than the diameter of the punching hole. Therefore, compared with punching along the moving direction of the material strip, the gap between the punching holes formed is smaller. Under the condition of the same length of the material strip, the number of punching holes formed by punching through the sway feeding device is greater, so that the material strip of the same length can obtain more discs, improve the utilization rate of the material strip, and reduce the production cost.

[0012] Furthermore, the distance between the center of each punching hole and the center line of the material strip is the same. When the material strip is punched, the material strip will swing, so that the center of the punching hole formed is located on one side of the center line of the material strip, and when the swing is performed, in order to improve the utilization rate of the material strip, the punching holes formed will be arranged in sequence along both sides of the center line of the material strip when the swing is performed, and the distance between the center of the punching hole and the center line of the material strip is the same, which not only ensures that the swing amplitude of the material strip can be kept consistent when the material strip is swinging, but also can limit the subsequent punching holes for forming, so that the subsequent punching holes are more accurate when being punched.

[0013] Furthermore, the stamping unit also includes a driving member that drives the stamping member to reciprocate and a limiting column arranged on both sides of the feeding channel, and the driving member is formed with limiting protrusions corresponding to the limiting columns. The driving member can drive the stamping member to move, and when the driving member moves, it can abut against the limiting columns on both sides of the feeding channel through the limiting protrusions, so that the driving member can be limited by the limiting columns. When the limiting protrusion abuts against the limiting column, it means that the stamping member has punched a punching hole at the material strip at this time, and the driving member will move in the opposite direction to move the stamping member out of the punching hole and realize the recovery of the wafer.

[0014] Furthermore, the deflection assembly also includes a plurality of rollers located at the front side of the clamping member, and the material belt moves to the clamping member along the rollers. The rollers are located at the front side of the clamping member, so the material belt will first reach the rollers and then be transported to the clamping member. By arranging a plurality of rollers at the front side of the clamping member, the material belt is smoother before entering the clamping member. At the same time, by arranging a plurality of rollers at the front side of the clamping member, it can also be ensured that the angle of the material belt changes less after the material belt reaches the clamping member from the rollers, so that the material belt enters the clamping member more smoothly.

[0023] like Figure 1 and Figure 2The present invention shows a slewing feeding device for processing a tapered bearing retainer, the slewing feeding device comprises a feeding unit 1 for conveying a material belt 3 and a punching unit 2 for forming punching holes 31 at the material belt 3; the feeding unit 1 comprises a feeding channel for moving the material belt 3 and a slewing assembly arranged at the moving path of the material belt 3, the slewing assembly comprises a clamping member and a slewing member 12 located on one side of the clamping member, the slewing member 12 can drive the material belt 3 to move in a direction perpendicular to the moving direction of the material belt 3, the clamping member comprises a first clamping plate 111 for supporting the material belt 3 and a second clamping plate 112 located on the upper side of the first clamping plate 111; the punching unit 2 comprises a punching member 21 located on the upper side of the feeding channel, the material belt 3 is sequentially formed with a plurality of punching holes 31 by the punching member 21, and the center of each punching hole 31 is located on one side of the center line of the material belt 3; wherein the slewing member 12 drives the material belt 3 In the moving state, a moving gap is formed between the first clamping plate 111 and the second clamping plate 112. When the stamping part 21 moves toward the material strip 3, the first clamping plate 111 and the second clamping plate 112 clamp the material strip 3 located therebetween. In the processing of the tapered bearing retainer, the material strip 3 is continuously stamped while moving, so that a plurality of discs are stamped out at the material strip 3. The discs can form a tapered bearing retainer after subsequent processing such as bottom cutting and punching. When punching the material strip 3, the discs are cut off from the material strip 3. The material strip 3 is usually a cube, and the stamped discs are cylinders. Therefore, a large amount of waste will be generated during the stamping process, namely, the surrounding areas of the stamped discs. Since the above-mentioned areas can no longer meet the area required for another disc, they cannot be processed further, thereby forming waste.

[0024] In the present application, by setting a feeding unit 1 and a stamping unit 2, when the material belt 3 moves in the feeding unit 1, the feeding unit 1 can not only satisfy the movement of the material belt 3 toward the stamping unit 2, but also can make the material belt 3 move in a direction perpendicular to the moving direction of the material belt 3 during the movement of the material belt 3, so that when the material belt 3 is stamped, the area where the stamping part 21 contacts the material belt 3 is not the center of the material belt 3, but is offset compared to the center line of the material belt 3. Accordingly, when the material belt 3 is stamped, the center of the stamping hole 31 formed after stamping will be located on one side of the center line of the material belt 3. When the material belt 3 continues to move, the feeding unit 1 can drive the material belt again. 3 is deflected, so that the stamping part 21 is located on the other side of the center line of the material strip 3, and stamping is performed. During stamping, since the relative position of the stamping part 21 and the material strip 3 is also changed, the positions of the two stamping holes 31 formed after sequential stamping are also staggered. Compared with the two stamping holes 31 being located on the same straight line, by making the material strip 3 deflect at the same time during the movement, the line connecting the centers of the two stamping holes 31 is inclined, and the spacing between the two stamping holes 31 along the moving direction of the material strip 3 is also reduced accordingly. The number of stamping holes 31 formed on the material strip 3 of the same length is also greater, thereby improving the utilization rate of the material strip 3 and reducing the production cost.

[0025] Among them, the feeding unit 1 includes a feeding channel and a deflection assembly arranged at the moving path of the material belt 3. The feeding channel is the area covered by the material belt 3. In order to prevent the material belt 3 from falling when moving, a supporting part, which is a part of the feeding channel, can be arranged at the moving path of the material belt 3. The material belt 3 is processed in an assembly line during processing, so the material belt 3 will be clamped between various components. Therefore, the material belt 3 can also be suspended during transportation without affecting the processing, and the area corresponding to the suspended material belt 3 is also a part of the feeding channel. The deflection assembly is arranged at the moving path of the material belt 3, so the material belt 3 will pass through the deflection assembly when moving, which can not only support the material belt 3, but also drive the passing material belt 3 to deflect, thereby changing the area where the stamping part 21 is stamped on the material belt 3, so that the stamping holes 31 formed on the material belt 3 are staggered; specifically, the deflection assembly includes The clamping member and the deflection member 12 located on one side of the clamping member, the first clamping plate 111 and the second clamping plate 112 in the clamping member can clamp the material strip 3 located therebetween, thereby fixing the material strip 3, and the deflection member 12 can drive the material strip 3 between the first clamping plate 111 and the second clamping plate 112 to deflect, and when the deflection member 12 drives the material strip 3 to move, a moving gap is formed between the first clamping plate 111 and the second clamping plate 112, so that the material strip 3 moves more smoothly, ensuring that the deflection member 12 can move the material strip 3 to the correct position, and will not interfere with other punching holes 31 during stamping. When the stamping member 21 moves toward the material strip 3, that is, the stamping member 21 stamps the material strip 3, the first clamping plate 111 and the second clamping plate 112 will clamp the material strip 3 located therebetween, thereby ensuring the stability of the material strip 3 during stamping, and also preventing the material strip 3 from deflecting during stamping.

[0026] In the present application, the spacing between two punching holes 31 sequentially formed on the material strip 3 by the stamping part 21 along the moving direction of the material strip 3 is smaller than the diameter of the punching hole 31; thus, compared with punching along the moving direction of the material strip 3, the gap between the formed punching holes 31 is smaller. When the length of the material strip 3 is the same, the number of punching holes 31 formed by punching through the eccentric feeding device is greater, so that the material strip 3 of the same length can obtain more discs, thereby improving the utilization rate of the material strip 3 and reducing the production cost.

[0027] Preferably, the distance between the center of each punching hole 31 and the center line of the material strip 3 is the same; when the material strip 3 is punched, the material strip 3 will swing, so that the center of the formed punching holes 31 are all located on one side of the center line of the material strip 3, and when the swing is performed, in order to improve the utilization rate of the material strip 3, the formed punching holes 31 will be arranged in sequence along both sides of the center line of the material strip 3 when the swing is performed, and the distance between the center of the punching hole 31 and the center line of the material strip 3 is the same, which ensures that the swing amplitude of the material strip 3 can remain consistent when the material strip 3 is swinging, and at the same time can limit the subsequent punching holes 31 to be formed, so that the subsequent punching holes 31 are more accurate when being punched.

[0028] As an embodiment of the present application, the deflection assembly also includes a plurality of rollers located on the front side of the clamping member, and the material belt 3 moves to the clamping member along the rollers; the rollers are located on the front side of the clamping member, so the material belt 3 will first reach the rollers and then be transported to the clamping member. By arranging a plurality of rollers on the front side of the clamping member, the material belt 3 is smoother before entering the clamping member. At the same time, by arranging a plurality of rollers on the front side of the clamping member, it can also be ensured that after the material belt 3 reaches the clamping member from the rollers, the angle change of the material belt 3 is small, making the entry into the clamping member smoother.

[0029] As an embodiment of the present application, the stamping unit 2 also includes a frame supporting the stamping part 21 and a limit member fixed to the frame, and the limit member is formed with a through hole 23 located on the lower side of the stamping part 21; the frame plays a supporting role, and the limit member is located on the lower side of the stamping part 21, so the limit member can carry the material strip 3, so that when the stamping part 21 is stamped, it plays a role of supporting the material strip 3, and the through hole 23 formed at the limit member corresponds to the stamping part 21, so the stamping part 21 can extend into the through hole 23 to pass through the material strip 3, thereby realizing the formation of the stamping hole 31.

[0030] In the present application, the stamping unit 2 also includes a driving member that drives the stamping part 21 to move back and forth and limiting columns arranged on both sides of the feeding channel, and the driving member is formed with limiting protrusions corresponding to each limiting column; the driving member can drive the stamping part 21 to move, and when the driving member moves, it can abut against the limiting columns on both sides of the feeding channel through the limiting protrusions, so that the driving member can be limited by the limiting columns. When the limiting protrusion abuts against the limiting column, it means that the stamping part 21 has been punched out at the material strip 3 to form a stamping hole 31, and the driving member will move in the opposite direction to move the stamping part 21 out of the stamping hole 31 and realize the recovery of the wafer.

[0031] As an embodiment of the present application, the stamping unit 2 also includes an air blowing member 24 arranged on one side of the limit member, and the air blowing member 24 is located at the upper end surface of the stamping hole 31; since the purpose of the present application is to obtain stamped discs when stamping the material strip 3, when the stamping member 21 is stamping, the stamping member 21 moves in a direction away from the material strip 3, and the stamped discs will be brought out. By setting the air blowing member 24, and the air blowing member 24 is located at the upper end surface of the stamping hole 31, when the stamping member 21 is separated from the stamping hole 31, the disc brought out at this time will correspond to the air blowing member 24, and gas will be generated at the air blowing member 24, thereby blowing the stamped disc, so that the disc is separated from the stamping member 21, which does not affect the stamping member 21 to stamp the material strip 3 again, and also facilitates the recovery of the disc.

[0032] Preferably, the stamping unit 2 also includes a recovery piece arranged opposite to the air blowing piece 24, the recovery piece and the air blowing piece 24 are respectively located on both sides of the limiting piece, and the height of the recovery piece gradually increases in the direction away from the air blowing piece 24; because the air blowing piece 24 will move the disc away from the air blowing piece 24 when blowing the disc formed after stamping, the recovery piece and the air blowing piece 24 are arranged opposite to each other and are respectively located on both sides of the limiting piece, so that the disc blown out by the air blowing piece 24 can smoothly enter the recovery piece, and the height of the recovery piece gradually increases in the direction away from the air blowing piece 24, which can not only block the disc through the high point at the far end to prevent the disc from crossing the recovery piece, but also the low point at the proximal end can ensure that the disc can smoothly enter the recovery piece.

[0033] In the present application, the limiter also includes a positioning column arranged in the stamping hole 31, the positioning column is coaxially arranged with the stamping hole 31, and the positioning column can move back and forth along the axial direction of the stamping hole 31; since the stamping part 21 can extend into the through hole 23, thereby passing through the material strip 3, so as to form a through stamping hole 31 at the material strip 3, and while the stamping hole 31 is formed, the disc will also be separated from the material strip 3 accordingly, so by setting the positioning column, the separated disc can fall on the positioning column, thereby preventing the disc from falling into the through hole 23, and the positioning column can move back and forth along the axial direction of the stamping hole 31, so when the stamping part 21 moves in a direction away from the through hole 23, the positioning column can also move in the same direction, so that the disc can be exposed from the through hole 23, and moved to correspond to the air blowing part 24 under the drive of the stamping part 21, so that it is blown into the recovery part by the air blowing part 24 for recovery.

[0034] As an implementation mode in the present application, an elastic member is sleeved on the outer side of the positioning column. When the stamping part 21 is stamped, the positioning column and the elastic member will be driven to contract. After the stamping part 21 is moved out, the positioning column will be reset under the drive of the elastic member, thereby realizing the reciprocating movement of the positioning column.

[0035] As an embodiment of the present application, the limiting member includes a first limiting plate 221 supporting the material strip 3 and a second limiting plate 222 located on the upper side of the first limiting plate 221. The punching hole 31 is formed at the second limiting plate 222, and the material strip 3 moves between the first limiting plate 221 and the second limiting plate 222. The first limiting plate 221 and the second limiting plate 222 can also ensure that the material strip 3 is in a flush state when punching the material strip 3, and the position of the formed punching hole 31 is more precise, avoiding interference with other punching holes 31, thereby ensuring the quality of the processed wafer.
