Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments, and it is apparent that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, based on the examples given, which a person of ordinary skill in the art would obtain without making any inventive effort, are within the scope of the utility model.
In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", etc. are based on the orientation or positional relationship shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element in question must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated.
1-2, the utility model discloses a sofa metal connecting piece stamping device, which comprises an uncoiling device 10 and a stamping die, wherein the stamping die comprises an upper stamping die 30 and a lower stamping die 40; the feeding device 20 comprises a first feeding roller 21, a second feeding roller 22, a gear 23 and a rack 25 which are arranged in parallel, wherein the steel belt passes through a gap between the first feeding roller 21 and the second feeding roller 22 and contacts with the roller surfaces of the first feeding roller 21 and the second feeding roller 22; the gear 23 is arranged at one end of the first feeding roller 21, and the gear 23 is connected with the first feeding roller 21 through a one-way bearing 24; the rack 25 is fixedly arranged on the upper stamping die 30, and when the upper stamping die 30 moves downwards, the rack 25 can be meshed with the gear 23; in order to avoid interference during engagement of the rack 25 with the gear 23, it is preferable that the lower end of the rack 25 is provided with a relief slope 251 toward the side where the gear 23 is located. The gear 23 drives the first feed roller 21 to move in the feed direction if and only if the upper punch die 30 is moved upward. Specifically, in this embodiment, the inner ring of the one-way bearing is installed on one end of the first feeding roller 21, the gear is sleeved on the outer ring of the one-way bearing, and certainly, the inner ring of the one-way bearing and the first feeding roller 21 can be driven (for example, tight fit or flat key fit), the outer ring of the one-way bearing and the gear can be driven (for example, tight fit or flat key fit) so that when the upper stamping die 30 drives the rack to move downwards, the rack is meshed with the gear and drives the gear to rotate, but the outer ring cannot drive the inner ring to rotate due to the characteristics of the one-way bearing, so that the first feeding roller 21 and the second feeding roller 22 do not rotate at this time, and the steel belt 50 is kept still; when the upper stamping die 30 moves upwards, the rack and the gear are still meshed, but the direction of rotation of the gear is opposite to the direction of rotation of the gear when the upper stamping die 30 moves downwards when the rack moves upwards, at this time, the outer ring of the one-way bearing can be driven to rotate anticlockwise (the rotation direction indicated by the arrow in fig. 1) towards the inner ring, so that after the steel strip is unwound by the unwinding device 10, the steel strip moves to the direction of the stamping die by a set length through the driving of the first feeding roller 21 and the second feeding roller 22. The set length is determined by the stamping die, after the set length is determined, the required number of turns of the gear is calculated according to the required feeding length and the diameters of the first feeding roller and the second feeding roller, and then parameters such as the meshing length of the rack and the gear, the number of teeth and the like are adjusted to change the number of turns of the gear, so that the feeding length requirement is met.
It should be noted that, the uncoiling device and the stamping die in this embodiment are not different from the prior art, and the stamping machine drives the upper and lower dies to move and the stamping action is also not different from the prior art, which is not described herein.
In addition, in order to provide a greater driving force to the steel strip and avoid the problem of slipping relative to the first feed roller 21 and the second feed roller 22, in this embodiment, it is preferable that the first feed roller 21 and the second feed roller 22 are provided with a first gear 261 and a second gear 262, respectively, at ends thereof remote from the gear 23, and the first gear 261 and the second gear 262 remain engaged; thus, the gear drives the first feed roller 21 to rotate, and simultaneously, the first transmission gear 261 and the second transmission gear 262 are meshed to drive the second feed roller 22 to rotate.
Therefore, the arrangement of the rack, the gear and the one-way bearing realizes that the first feeding roller and the second feeding roller are driven to rotate in the upward moving process of the upper stamping die, so that the feeding of the steel belt is realized; simple structure, the cost input and the maintenance cost of equipment are low to it drives the cooperation punching press feeding to follow the stamping action of last stamping die, and synchronism matching degree is better.
The above embodiments are only preferred embodiments of the present utility model, and are not intended to limit the scope of the present utility model in this way, therefore: all equivalent changes in structure, shape and principle of the utility model should be covered in the scope of protection of the utility model.
