Detailed Description
The invention will be further described with reference to the drawings and examples.
As shown in fig. 1 to 4, the synchronous wire feeding structure for in-mold riveting of the invention comprises a unidirectional transmission mechanism 2 and a wire feeding mechanism 3 which is arranged on a static die holder 12 of a riveting die 1 and is used for conveying riveting wires into the riveting die 1; the wire feeding mechanism 3 comprises a driving roller 31 and a driven roller 32 which are arranged on the static die holder 12, the driven roller 32 is arranged on one side of the driving roller 31 and is parallel to the driving roller 31, and a wire feeding groove 33 is arranged between the driving roller 31 and the driven roller 32. The driving roller 31 and the driven roller 32 may be mounted on the stationary die holder 12 by bearings, in particular. One end of the unidirectional transmission mechanism 2 is connected with the movable die holder 11 of the riveting die 1, and the other end is in transmission connection with the driving roller 31, so that the driving roller 31 is only driven to rotate in the feeding direction when the movable die holder 11 moves towards the direction close to the static die holder 12; or, the driving roller 31 is driven to rotate in the feeding direction only when the movable die holder 11 moves away from the stationary die holder 12.
Referring to fig. 1, in the embodiment of the present invention, the static die holder 12 is a lower die holder of the riveting die 1, and the movable die holder 11 is an upper die holder of the riveting die 1. The feeding direction of the feeding mechanism 3 may be various directions, such as along the moving direction of the movable die holder 11 or along the moving direction perpendicular to the movable die holder 11, and is generally determined according to the process of punching and riveting the product. In fig. 1, the feeding direction of the wire feeding mechanism 3 is upward feeding along the moving direction of the movable die holder 11.
In the present invention, the choice of driving roller 31 only when the movable die holder 11 moves toward the stationary die holder 12 or driving roller 31 only when the movable die holder 11 moves away from the stationary die holder 12 is also determined according to the process of riveting the product. In fig. 1, for convenience of riveting, it is preferable to drive the drive roller 31 only when the movable die holder 11 moves in a direction away from the stationary die holder 12 (upward movement).
In the present invention, the wire for producing rivets is passed through the wire feed groove 33 at the time of production. Referring to fig. 1, the driving roller 31 is driven only when the movable die holder 11 moves in a direction away from the stationary die holder 12 (upward movement) as an example. According to the in-mold riveting synchronous wire feeding structure, the unidirectional transmission mechanism 2 is arranged between the wire feeding mechanism 3 and the movable die holder 11 of the riveting die 1, when the movable die holder 11 moves in the direction away from the static die holder 12, namely upwards, the movable die holder 11 can drive the driving roller 31 to rotate clockwise through the unidirectional transmission mechanism 2, so that wires are vertically and upwards fed into the riveting die 1, and when the movable die holder 11 moves in the direction close to the static die holder 12, namely downwards, the unidirectional transmission mechanism 2 is in unidirectional transmission, the driving roller 31 cannot be transmitted in the process, namely the driving roller 31 cannot rotate in the process, and the feeding is stopped, so that the wires are conveniently cut off (riveting) when the movable die holder 11 moves downwards. According to the invention, the driving roller of the wire feeding mechanism 3 is connected with the movable die holder 11 of the riveting die 1 through the unidirectional transmission mechanism 2, so that the driving roller and the movable die holder 11 form a linkage body, the synchronism between the driving roller and the movable die holder can be accurately ensured, and the smooth production can be ensured.
As shown in fig. 4, in the embodiment of the present invention, the unidirectional transmission mechanism 2 includes a swing arm 22, a unidirectional transmission device 23, and a connection member 21 for driving the swing arm 22 to rotate; one end of the swing arm 22 is in transmission connection with the driving roller 31 through the unidirectional transmission device 23, one end of the connecting piece 21 is connected with the movable die holder 11, and the other end of the connecting piece is hinged with the other end of the swing arm 22 through the hinge shaft 24, so as to form a transmission mechanism for enabling the swing arm 22 to rotate. One end of the connecting piece 21 can be hinged with the movable die holder 11, and when the hinge shaft 24 can move along the swing arm in the swing process of the swing arm, the connecting piece 21 can also be fixedly connected with the movable die holder 11. The one-way transmission 23 may be a ratchet mechanism, one-way bearing, one-way clutch, or the like. In the embodiment of the invention, the unidirectional transmission device 23 is a unidirectional bearing, one end of the swing arm 22 is fixedly connected with an outer ring of the unidirectional bearing, and an inner ring of the unidirectional bearing is sleeved and fixed on the driving roller 31. With continued reference to fig. 1, taking a one-way bearing as an example of clockwise one-way transmission, when the movable die holder 11 moves upwards, the movable die holder 11 drives the swing arm 22 to rotate around the swing arm 22 through the connecting piece 21, and the swing arm 22 drives the driving roller 31 through the one-way bearing, so that the driving roller rotates clockwise; when the movable die holder 11 moves downwards, the swing arm is reset under the action of the connecting piece 21 or the action of dead weight, but the unidirectional bearing is in clockwise unidirectional transmission, at the moment, the driving roller does not rotate, and feeding is stopped. When the movable die holder 11 moves upwards again, the movable die holder 11 drives the swing arm 22 to rotate through the connecting piece 21, so that the driving roller rotates clockwise to feed materials. In fig. 1, the connecting piece 21 may be a connecting rod, and if the swing arm can reset by means of its own weight, the connecting piece 21 may also be a rope.
In some embodiments, the unidirectional transmission mechanism may also adopt a structure of a gear, a rack and a unidirectional transmission device, wherein the gear is in transmission connection with the driving roller 31 through the unidirectional transmission device 23, and the rack is mounted on the movable die holder 11 and meshed with the gear. Namely, when the movable die holder 11 moves, the rack is driven to move, so that the gear is driven, and then the gear drives the driving roller to rotate unidirectionally through the unidirectional transmission device.
In actual production, there is a case where the feeding length of the wire rod is adjusted. When the feeding length of the wire rod needs to be adjusted, the wire rod feeding device can be realized by adjusting the swing amplitude of the swing arm. The swing amplitude of the swing arm can be adjusted by changing the stroke of the movable die holder 11 and replacing the connecting piece 21 with the matched length. In practice, however, this is relatively inconvenient. For this purpose, in the present invention, the swing arm 22 is provided with a bar hole 221 along the length direction of the swing arm 22, the hinge shaft 24 is disposed in the bar hole 221 and is in sliding fit with the hinge shaft in a rotating manner, so that the hinge shaft 24 can rotate in the bar hole 221 and slide along the bar hole 221, and one end of the connecting piece 21 is fixedly connected with the movable die holder 11. Thus, it is possible to change only the length of the connection member 21, such as: the amplitude of the swing arm 22 can be changed by changing the connecting pieces 21 with different lengths. One end of the connecting piece 21 is fixedly connected with the movable die holder 11, and particularly can be connected by bolts, clamped connection and the like
When the connecting piece 21 is a connecting rod, in order to change the length of the connecting piece 21 conveniently, the connecting piece 21 is of a length-adjustable structure, and can be of various existing telescopic rod structures. As shown in fig. 5, in the embodiment of the present invention, the connecting member 21 includes a first screw 211 and a second screw 213, the threads of the first screw 211 and the second screw 213 are opposite, and the first screw 211 and the second screw 213 are screwed and connected by a nut 212 with left and right threads. Thus, the length of the connector 21 can be adjusted by rotating the nut 212, and the connector does not need to be replaced.
In the embodiment of the present invention, two ends of the driven roller 32 are respectively provided with a sliding block 34 slidably connected with the static mold holder 12 along the connection line direction of the driving roller 31 and the driven roller 32, two ends of the driven roller 32 are respectively rotatably connected with the sliding blocks 34 at corresponding ends through bearings, and one side of the sliding block 34 away from the driving roller 31 is provided with a third screw 35 for adjusting the distance between the sliding block 34 and the driving roller 31. In this way, the third screw 35 can slide the slider 34 in a direction approaching the driving roller 31, so that the distance between the driven roller 32 and the driving roller 31 is adjusted, and the size of the wire feeding groove 33 is adjusted, so that the driving roller 31 and the driven roller 32 can clamp the wire better, and the wire is convenient to convey.
As shown in fig. 3 and 4, the driven roller 32 of the present invention may not be provided with a driving mechanism. For better feeding, in the embodiment of the invention, a facing transmission mechanism 4 for driving the driven roller 32 to rotate opposite to the driving roller 31 is arranged between the driving roller 31 and the driven roller 32. The driven roller 32 rotates in opposition to the drive roller 31, i.e., when the drive roller 31 rotates counterclockwise, the driven roller 32 rotates clockwise, whereas the driven roller 32 rotates counterclockwise. Specifically, the facing transmission mechanism 4 includes a first sub gear 41 and a second gear 42, the first sub gear 41 is fixedly mounted on the driving roller 31, and the second gear 42 is fixedly mounted on the driven roller 32 and meshes with the first sub gear 41. Thus, when the driving roller 31 rotates clockwise, the driven roller 32 is driven to rotate anticlockwise through the first gear 41 and the second gear 42, and conversely, the driven roller 32 is driven to rotate clockwise. In some embodiments, the counter drive 4 is also a chain or belt drive.
