[ detailed description ] embodiments

Example (b):

referring to fig. 1 to 4, the present embodiment is a rack and pinion transmission crimping apparatus 100, which is used to crimp two sheet frames 101 and 102 together, where the two sheet frames have overlapping portions corresponding to the sheet surfaces, and the upper and lower edges of the sheet surface of one sheet frame are both folded with crimping pieces 103 perpendicular to the sheet surface, and the corresponding sheet surface of the other sheet frame is located between the upper and lower sets of crimping pieces 103, and when crimping, the crimping pieces 103 are respectively bent upwards or downwards to buckle the corresponding edge of the other sheet frame, thereby completing the crimping.

The embodiment is a crimping device 100 driven by a gear and a rack, and the crimping device comprises a supporting frame 3, a driving cylinder 1 and a rotating gear 5 fixed on the supporting frame 3, a guide rod 6 vertically fixed on the supporting frame 3, an upper movable block 7 driven by the driving cylinder 1 to slide up and down on the guide rod 6, a lower movable block 8 arranged on the guide rod 6 and capable of sliding up and down, an upper crimping block 9 fixed on the upper movable block 7, and a lower crimping block 10 fixed on the lower movable block 8, wherein a first rack 11 meshed with the rotating gear 5 is fixed on the upper movable block 7, and a second rack 12 meshed with the rotating gear 5 is fixed on the lower movable block 7.

And a limiting block 4 for limiting the end part of the shell frame and the upper limit height is fixed on the guide rod 6. And a limiting block 4 for limiting the end part of the shell frame and the upper limit height is fixed on the guide rod 6. The two side edges of the sheet frames 101 and 102 can be limited by the limiting block 4, the upper limit of the two sheet frames can be pressed, the sheet frames are prevented from being deformed due to stress caused by thinness in the crimping process, and the crimping quality is guaranteed.

The upper compression joint block 9 and the lower compression joint block 10 have the same structure and are provided with compression joint clamping grooves 2. High one side low on both sides upper portion surface of crimping draw-in groove 2 is high surface 13 and low surface 14 respectively, this low surface 14 corresponds the setting with crimping piece 103, when the crimping, crimping draw-in groove 2 advances into two piece frame overlap joint parts, and live in the overlap joint face base or the last side parcel of two piece frames, then the crimping piece continues upwards or downstream, make crimping piece 103 fall on low surface 14, continue upwards or downstream again, upwards or buckle crimping piece 103 downwards and live in another piece frame face and realize the crimping, because overlap joint face base or the higher authority of two piece frames have been wrapped up in advance through crimping draw-in groove 2, make the higher authority or lower side of piece frame can not take place deformation in the crimping in-process, ensured going on smoothly and the crimping quality.

The working principle of the crimping unit is that the whole crimping module is switched between a crimping position and an initial position through the fifth cylinder 1; when the whole crimping module moves to a crimping position, the driving cylinder 1 drives the lower movable block 8 to move upwards, the upper movable block 7 and the lower movable block 8 synchronously move up and down through the meshing transmission of a second rack 12 on the lower movable block 8 and the rotating gear 5 and the meshing transmission of the rotating gear 5 and a first rack 11 on the upper movable block 7, and therefore the upper crimping block 9 and the lower crimping block 10 synchronously and respectively crimp the crimping pieces from the upper side and the lower side of the shell product; the two crimping units respectively complete the crimping connection of the two sheet frames from the two ends of the shell product.

In the embodiment, the rack-and-pinion driven crimping device 100 drives the movable block to move up and down through the cylinder, the rack is arranged on the movable block, the rack and the pinion are used for realizing the synchronous up-and-down movement of the upper movable block and the lower movable block, the crimping blocks are arranged on the upper movable block and the lower movable block respectively for realizing the crimping of the upper edge and the lower edge of the sheet, and the crimping efficiency is high and the crimping effect is good; compared with the traditional press connection, the volume and the occupied space are greatly reduced, and the noise is greatly reduced.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
