DETAILED DESCRIPTION

[0025] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0026] like Figure 1-Figure 7As shown, a stamping die for iron handicrafts with an interval material distribution mechanism includes a press machine 1, an upper die 2 and a lower die 3, wherein the upper die 2 and the lower die 3 are butt-jointed up and down, the upper die 2 is fixed to the movable end of the press machine 1 to be away from or close to the lower die 3, a punch 21 is fixed on the upper die 2, a knife seat 31 is fixed on the lower die 3, a knife edge 32 which cooperates with the punch 21 and is used to form a product is opened on the knife seat 31, a blanking cavity 33 which is connected to the knife edge 32 is provided on the lower die 3, a material distribution mechanism 4 is provided in the lower die 3, and the material distribution mechanism 4 includes a slide plate 4 1. The disc 42 and the first stepper motor 43 are arranged in the blanking cavity 33 with the slide plate 41 tilted. The slide plate 41 is provided with a through hole 411, and a ring-shaped platform 412 is provided in the through hole 411. A material dividing member 44 is slidably penetrated on the platform 412. The upper end of the material dividing member 44 is provided with a stopper 441 and the lower end is provided with a bottom support 442. The lower end surface of the bottom support 442 is provided with a limiting groove 4421. A rolling body 443 is rotatably provided in the limiting groove 4421. The outer cover of the material dividing member 44 is provided with a spring 45. The two ends of the spring 45 are respectively fixedly connected with the platform 412 and the bottom support 442. The disc 42 is fixedly connected to the output shaft of the first stepper motor 43. The upper end surface of the disc 42 is evenly provided with a plurality of adjustment grooves 421 in the circumferential direction. The upper end surface of the disc 42 is provided with an annular ring groove 422 connected with the adjustment groove 421. The depth of the adjustment groove 421 is greater than the ring groove 422. The rolling body 443 rolls with the adjustment groove 421 and the ring groove 422. A material receiving rack 5 is provided on one side of the lower mold 3. The material receiving rack 5 includes an inclined table 51 and a support plate 52 for supporting the table 51. A plurality of material trays 6 are slidably provided on the table 51. The material trays 6 are provided with a plurality of material trays 6. A number of partitions 61 are evenly separated into a number of material troughs 62 that are connected to the blanking cavity 33. A material-dispensing mechanism 7 is provided on the material receiving frame 5. The material-dispensing mechanism 7 includes a disc-shaped material-dispensing plate 71 and a second stepper motor 72 fixed on the support plate 52. A rack 63 is provided on the lower end surface of the material tray 6. A notch 511 that is connected to the rack 63 is opened on the table top 51. The material-dispensing plate 71 is eccentrically fixed to the output shaft of the second stepper motor 72. A dial plate 73 is fixed to the outside of the material-dispensing plate 71. A number of tooth heads 731 that can be engaged with the rack 63 are evenly provided on the upper end of the dial plate 73.

[0027] like Figure 1 As shown, the upper die 2 is provided with a guide sleeve 22, and the lower die 3 is provided with a guide post 34 that is slidably plugged with the guide sleeve 22. The sliding plug-in cooperation between the guide sleeve 22 and the guide post 34 can effectively improve the stability of the upper die 2 and the lower die 3 during die stamping, and improve the quality of the stamped product.

[0028] like Figure 7 As shown, the lower end of the dial plate 73 is provided with a slot 732, and one side of the support plate 52 has a protruding limit column 521 that slides with the slot 732. The slot 732 is located at the lower end of the dial plate 73, and the upper end tooth head 731 is ensured to be in contact with the limit column 521 through the sliding limit cooperation.

[0029] like Figure 5 As shown, the joint of the adjusting groove 421 and the annular groove 422 is connected by an inclined surface 423. When the rolling body 443 rolls between the adjusting groove 421 and the annular groove 422, the inclined surface 423 makes the transition between the two more stable.

[0030] The lower mold 3 is provided with a sleeve 35 which is sleeved outside the bottom support 442 and slidably cooperates with the bottom support 442. The bottom support 442 is restricted to slide in the sleeve 35, so that the upper and lower ends of the material dividing member 44 move more stably.

[0031] like Figure 4 As shown, the bottom support 442 is provided with an oil injection hole 4422 connected to the limiting groove 4421. The oil injection hole 4422 facilitates lubrication of the rolling body 443 in the limiting groove 4421, without the need to dismantle the entire material distribution mechanism 4, so that the subsequent maintenance cost is low.

[0032] The rolling body 443 is one of a ball, a roller or a bearing. The rolling body 443 is a ball, a roller or a bearing, which is not only convenient to obtain materials but also low in cost.

[0033] The stopper 441 is made of elastic material, which can provide a buffer for the stamping product.

[0034] The practical working principle of the utility model is as follows: the stamping part falls into the blanking cavity 33 through the knife edge 32, and the first stepper motor 43 drives the disc 42 to rotate, so that the rolling body 443 intermittently rotates along the adjusting groove 421 and the annular groove 422. Since the depth of the adjusting groove 421 is greater than the annular groove 422, when the rolling body 443 is located in the adjusting groove 421, the stopper 441 retracts into the through hole 411, and the stamping part can smoothly pass through the blanking cavity 33 and enter the trough 62. When the rolling body 443 is located in the annular groove 422, the stopper 441 extends out of the through hole 411, and the stopper 441 blocks the stamping part. The speed and the dwell time of the first stepper motor 43 are set by the speed of the stamping die of the press machine 1, so as to achieve the purpose of the stamping parts passing through the blanking cavity 33 one by one or several times intermittently and entering the trough 62;

[0035] When a material trough 62 is full of stamping parts, the second stepper motor 72 drives the material disc 71 to rotate. Since the material disc 71 is eccentrically fixed to the output shaft of the second stepper motor 72, the rotation of the material disc 71 drives the dial plate 73 to slide the material disc 6. At this time, the tooth head 732 drives the rack 63 forward several grids, so that the next material trough 62 is aligned with the blanking cavity 33, until the entire material disc 6 is full of stamping parts. The worker then takes the material disc 6 away for the next step of processing, effectively storing and processing the stamping parts, and effectively improving the efficiency of subsequent processing of the stamping parts.

[0036] The specific embodiments described herein are merely examples of the spirit of the present invention. A person skilled in the art of the present invention may make various modifications or additions to the specific embodiments described or replace them in a similar manner, but this will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
