The large die carrier 2 comprises a top plate and a base, and the top plate is movably connected with the base through a large die carrier guide post 3. The hydraulic cylinder 1 is located above the top plate and connected with the top plate, the four large die set guide pillars 3 are fixedly installed at four corners of the base, and the top plate can move up and down along the large die set guide pillars 3 under the driving of the hydraulic cylinder. The structure can be realized in different ways: if four corners of the top plate are provided with round holes, the large die set guide post 3 is sleeved with a return spring, and the large die set guide post 3 passes through the round holes to enable the top plate to move up and down; the sleeves can also be fixedly installed at four corners of the bottom of the top plate, the reset spring is sleeved on the large die set guide post 3, and the sleeves of the top plate are sleeved on the large die set guide post 3.
The base of the large die carrier is fixedly provided with a lower forming die 5 and a lower die carrier 7, the middle part of the lower forming die 5 is provided with a groove 501, an upper forming die 4 is arranged right above the groove 501, and the top end of the upper forming die 4 is fixedly arranged at the bottom of the top plate of the large die carrier. The two sides of the groove 501 are both platforms, a positioning block 11 is fixedly mounted on the platform on one side, a plane with a certain distance is reserved between the side end face of the positioning block 11 close to the groove 501 and the edge of the groove 501, and the distance from the side end face of the positioning block 11 to the edge of the groove 501 is adjustable. A kidney-shaped hole can be arranged on the positioning block 11, and the distance can be adjusted through the matching of a bolt and the kidney-shaped hole. The platform on the other side of the groove 501 is an objective table and is used for temporarily storing the staple strip sections which are cut off, because the staple strip sections which are cut off are easy to curl up, if the positions on the objective table are inclined, the length of penetrating parts on the two sides of the staple can be different when the staple strip sections are pushed to the groove 501 for forming, and the production quality is affected. Therefore, in this embodiment, the upper surface of the object stage is set as the magnet object stage 502, so that the staple strip section can be firmly adsorbed on the object stage, and because the staple strip section is tightly attached to the object stage, the staple strip section can be kept at the same position and at the correct position when being pushed to the groove 501 for molding, and the problem that the penetration portions of the staples are different in length cannot occur.
The lower knife rest 7 is fixedly arranged beside the lower forming die 5 and located on the feeding side of the staple strip, the top of the lower knife rest 7 is kept horizontal with the object stage, the lower blade 9 is fixedly arranged on the side face, close to the lower forming die 5, of the lower knife rest 7, the lower blade 9 is clamped between the lower forming die 5 and the lower knife rest 7, and the top height of the lower blade 9 is kept consistent with the plane of the object stage. An upper knife rest 6 is arranged above the lower knife rest 7, and an upper blade 10 is fixedly arranged on the side surface of the upper knife rest 6 close to the lower forming die 5. The upper blade 10 and the lower blade 9 are aligned up and down, two blade holder guide pillars 8 are arranged at the bottom of the upper blade holder 6, two guide pillar holes are formed in the top of the lower blade holder 7, a reset spring is arranged in each guide pillar hole, the top end of each blade holder guide pillar 8 is fixedly connected with the bottom surface of the upper blade holder 6, and the bottom end of each blade holder guide pillar 8 is inserted into each guide pillar hole. In order to ensure a high tool setting accuracy of the upper blade 10 and the lower blade 9, the stroke distance of the downward movement of the upper tool carrier 6 should be designed to be as short as possible. The downward movement of the upper tool rest 6 depends on the downward pressing of the top plate of the large die carrier, and a pressing block 13 can be arranged at the bottom of the top plate of the large die carrier, so that the upper tool rest 6 moves downward through the contact of the pressing block 13 and the top of the upper tool rest 6, and the moving stroke of the large die carrier 2 is shortened.
When the cutting and forming device is used for producing the staple, the cutting and forming method comprises the following steps: the cutting and forming device is abutted with the staple feeding device, and the staple strip 12 (in a state of not being cut and formed) conveyed by the feeding device directly enters the cutting and forming device from the outer side of the lower knife rest 7. In the initial state, the top plate of the large die carrier is not pressed down, the upper blade 10 and the lower blade 9 are separated at the moment, and the feeding device starts to work to convey the head end of the staple strip 12 to the magnet carrying platform 502 of the cutting device. If the staple strip 12 is cut and formed for the first time, the leading end of the staple strip 12 is directly conveyed to the magnet carrier 502, and the conveying length of each time is set according to the type of staple produced. If the continuous operation is performed, there is always a staple line section cut at the top of the recess 501. After the staple strip section is conveyed to the magnet carrying platform 502 by the feeding device, the feeding device stops conveying, the hydraulic cylinder 1 starts to press the top plate of the large die carrier downwards, the upper forming die 4 and the upper blade 10 synchronously start to move downwards, the head end of the staple strip 12 is cut off under the combined action of the upper blade 10 and the lower blade 9 to form a new staple strip section, and at the moment, the other staple strip section above the groove 501 of the lower forming die 5 is also synchronously punched and formed by the upper forming die 4 and the lower forming die 5. After finishing the cutting and forming action for one time, under the action of a return spring on a guide post 3 of a large die carrier, an upper forming die 4 and an upper knife rest 6 are moved upwards by a synchronous belt, at the moment, a feeding device starts to continue to convey, the head end of a staple strip 12 is conveyed to a magnet carrying platform 502, the staple strip section which is cut off in the previous round is pushed to the upper part of a groove 501 under the conveying pushing of the staple strip 12, the staple strip section which is formed in the previous round is pushed out of the groove 501 by a conveying mechanism, and the cutting and forming action in the previous round is continuously repeated in this way, and the cutting and forming action is executed in a circulating reciprocating way. Because the magnet carrying platform 502 can well adsorb the staple strips 12, even if the staple is cut into staple strip sections, the staple strip sections can not be displaced due to curling, and the original positions can be still kept after cutting, so that the subsequent forming is facilitated, the cut staple strip sections can be well pushed to the grooves 501 by the staple strips 12, the positions of the staple strip sections before forming are further ensured to be correct through the positioning effect of the positioning blocks 11, and the forming quality is ensured. Cutting and shaping remain synchronous throughout, have further promoted production efficiency.
