Abstract
Description
Technical Field
[0001] The utility model relates to the field of stamping processing equipment, in particular to a stamping machine for processing book rings and clip rings. Background Art
[0002] Each page of the book is provided with a hole that passes through the paper, and a circular book ring passes through each hole to limit each page of paper, and each page of paper is connected in series to form a book. The same hole positions as the book are provided on the hard cardboard, and the user can use the card ring to connect multiple hard cardboards in series; the above-mentioned book ring and card ring are both composed of two half rings 121 (reference Figure 11 ), one end of the two half rings are rotatably connected to each other, and the other end of the half ring is provided with a buckle, and the two buckles are engaged with each other. When the user wants to remove a single piece of paper or a single piece of hard cardboard separately, the two buckles are unfastened and the two half rings are opened, so that the user can remove the paper in the book ring or the hard cardboard in the card ring; the structure of the book ring is the same as that of the card ring, the difference is that the diameter size of the cross section of the half ring is different. Since the book is thicker, a stronger book ring is required for combination, so it is necessary to use a half ring with a wider cross-sectional diameter. The card ring only needs to connect a small amount of hard cardboard in series. In order to make the card ring lighter and reduce production materials, it is only necessary to use a half ring with a narrow cross-sectional diameter.
[0003] There are four steps in the processing of the half ring of the book ring. The first step is to punch and flatten the end of the material strip, the second step is to punch holes in the flattened part of the material strip, the third step is to bend the material strip into a semicircle, and the fourth step is to punch and cut off the part of the material strip bent into a semicircle and punch out the buckle to complete the processing of a single half ring of the book ring.
[0004] The equipment that completes the above four processing steps has three stamping mechanisms, which respectively realize stamping flattening, stamping punching and stamping cutting. The three stamping mechanisms make the existing processing equipment too large and require a high layout area. Utility Model Content

[0066] The first central axis 32 rotates 180 degrees for the fourth time, and the first central axis 32 drives the second central axis 52 to rotate 90 degrees for the fourth time through the transmission chain 34. The second connecting rod 33 pulls the rocker arm 23 to swing. Since the one-way bearing can only rotate in one direction, the feeding mechanism 2 stops running, so that the end of the material strip 12 is located in the second processing groove; the second central axis 52 pushes the adjusting rod 411 to rotate a certain angle through the first connecting rod 53, so that the adjusting rod 411 rotates to the top of the second contact portion 93, and the second central axis 52 pushes the reciprocating slide 551 to slide and hit the contact block 73 through the third connecting rod 54, so that the cutting knife 72 slides into the knife box 71 to cut the material strip 12 to form a semi-ring 121, and the forming groove cuts out the shape of a buckle on the semi-ring 121. The first central axis 32 drives the stamping mechanism 4 to run for the second time. The stamping mechanism 4 pushes the stamping disk 41 close to the processing mechanism 6, so that the adjusting rod 411 hits the second contact part 93, and the second contact part 93 pushes the punching knife 94 to penetrate the material strip 12. The stamping mechanism 4 pulls the stamping disk 41 to reset, and the second spring 931 pushes the second contact part 93 to reset; the jet mechanism 11 blows the semi-ring 121 in the first processing groove, and blows the semi-ring 121 away from the processing mechanism 6 to complete the processing.
[0067] The utility model provides a punching machine for processing book rings and card rings, wherein a driving mechanism drives a feeding mechanism to operate, and the feeding mechanism pushes a material strip to touch an inclined guide plate. The inclined guide plate can change the extension direction of the material strip and also bend the material strip to form an arc shape. The end of the material strip passes through a cutting component and enters a first processing groove. The driving mechanism drives the punching mechanism to operate, and the punching mechanism pushes an adjusting rod on a punching disk to hit a flattening block, so that the flattening block punches and flattens the material strip in the first processing groove; the feeding mechanism pushes the end of the material strip to pass through the first processing groove and then enter the second processing groove, and the driving mechanism drives the reciprocating mechanism to operate, and the reciprocating mechanism passes through the first processing groove. The connecting rod pushes the adjusting rod to rotate above the punching knife, and the punching mechanism pushes the adjusting rod on the punching disk to hit the punching knife, so that the punching knife penetrates the material strip in the second processing groove. When punching, the reciprocating mechanism drives the reciprocating slide to slide a certain distance to hit the cutting knife, so that the cutting knife can slide a certain distance on the cutting assembly to cut the material strip to form a half ring of the book ring. The forming groove of the cutting knife can cut out the shape of the buckle in the half ring when cutting, completing the four processing steps of the half ring; compared with the multiple stamping mechanisms of the existing equipment, the equipment in this scheme only uses one driving mechanism to drive the feeding mechanism, stamping mechanism and reciprocating mechanism to operate synchronously, thereby reducing the size of the equipment.
[0068] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
