[0003] The utility model of the existing authorized application number CN214726429U discloses a bending position shaping die for a bag cover piece. By adopting the above technical solution, the cover piece is shaped by the bending position of the U-shaped part, so that the shaping effect of the cover piece is good, effectively preventing the cover piece from deforming. The cover piece is positioned by the first limiting part and the second limiting part, so that the positioning between layers is accurate, avoiding rework or even scrapping caused by inaccurate manual positioning. However, the above technical solution can only limit the position of the cover piece through the U-shaped part, the first limiting part and the second limiting part, but it is not convenient to take out the shaped cover piece during bending position shaping, and only one bag cover piece can be bent and shaped at a time, resulting in the problem of reduced efficiency of bending position shaping of the bag cover piece.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] In order to better understand the purpose, structure and function of the present utility model, the following further describes in detail a bending and shaping die for a bag cover piece of the present utility model with reference to the accompanying drawings.

[0024] Please refer to Figures 1-5 , the present utility model: a bending and shaping die for a bag cover piece, including a bottom plate 1. Four fixed columns 2, four bases 16 and a protective housing 5 are respectively fixedly connected to the upper surface of the bottom plate 1. The tops of two groups of fixed columns 2 are commonly fixedly connected to a top plate 3. Two hydraulic cylinders 7 are fixedly connected to the bottom surface of the top plate 3. Two fixed rings 4 are respectively fixedly connected to the outer surfaces of each group of fixed columns 2. The bottom ends of each group of fixed rings 4 are fixedly connected to the upper surface of the bottom plate 1. Through the fixed rings 4, the fixed columns 2 and the bottom plate 1 can be fixed, with a strong reinforcement effect and enhanced stability of the device.

[0025] The telescopic ends of two hydraulic cylinders 7 are fixedly connected together with a lower pressing plate 11. Four pressing blocks 12 are fixedly connected to the bottom surface of the lower pressing plate 11. Eight springs 18, four limiting vertical plates 17 and four limiting side plates 19 are fixedly connected to the upper surface of each group of bases 16. A protective seat 8 is fixedly connected to the outer surface of each hydraulic cylinder 7. The upper surface of each protective seat 8 is fixedly connected to the bottom surface of the top plate 3. Through the protective seat 8, the hydraulic cylinder 7 can be protected, playing a strong protective role and effectively preventing the problem of being interfered by the outside world during its working process.

[0026] Above each group of bases 16, there are two mold bodies 13 arranged. Two grooves 14 are formed on the upper surface of each group of mold bodies 13. The bottom surface of each group of mold bodies 13 is in contact with the top end of the spring 18. A reinforcing plate 9 is fixedly connected to the outer surface of the telescopic end of each hydraulic cylinder 7. The bottom surface of each reinforcing plate 9 is fixedly connected to the upper surface of the lower pressing plate 11. Through the reinforcing plate 9, the hydraulic cylinder 7 and the lower pressing plate 11 can be reinforced, effectively avoiding the problem of deviation and instability during their use.

[0027] One side surface of each group of limiting vertical plates 17 close to each other is in contact with the outer surface of the mold body 13. Four support feet 6 are fixedly connected to the bottom surface of the bottom plate 1. Four fixing bolts 10 are threadedly connected to the inner wall of each reinforcing plate 9. The outer surface of each group of fixing bolts 10 is threadedly connected to the inner wall of the lower pressing plate 11. Through the fixing bolts 10, the reinforcing plate 9 and the lower pressing plate 11 can be fixed to prevent their positions from shifting during the working process.

[0028] Eight fastening bolts 15 are threadedly connected to the inner wall of each group of bases 16. The outer surface of each group of fastening bolts 15 is threadedly connected to the inner wall of the bottom plate 1. Two limiting rings 20 are fixedly connected to the outer surface of each group of springs 18. The bottom end of each group of limiting rings 20 is fixedly connected to the upper surface of the base 16. Through the limiting rings 20, the position of the spring 18 can be restricted to prevent its position from shifting and becoming unstable during use.

[0029] The working principle of the present utility model is as follows: First, place the bag cover piece to be bent and shaped on the mold body 13. Then, by extending the telescopic end of the hydraulic cylinder 7, drive the lower pressing plate 11 to move downward, and further drive the pressing block 12 to move downward, so as to be able to press down the bag cover piece workpiece on the mold body 13. And under the pre-tightening force of the spring 18, the mold body 13 will not move downward. Through the limiting vertical plate 17, the flange edge of the bag cover piece workpiece will not wrinkle or deform. When the acting force of the pressing block 12 exceeds the pre-tightening force of the spring 18, the bag cover piece workpiece will move downward together with the mold body 13. When the mold body 13 moves downward to the upper surface of the limiting side plate 19, the mold body 13 stops moving. Then, by making the pressing block 12 continue to move downward a little distance until the bag cover piece workpiece contacts the surface of the groove 14, the purpose of bending and shaping the bag cover piece workpiece is achieved. Then, by contracting the telescopic end of the hydraulic cylinder 7, drive the lower pressing plate 11 and the pressing block 12 to move upward. Further, the mold body 13 and the bag cover piece workpiece move upward under the driving force of the spring 18. And during the upward or downward movement of the bag cover piece workpiece, the flange edge will slide on the limiting vertical plate 17, which helps the bag cover piece workpiece to separate from the mold body 13, achieving the purpose of easily taking out the workpiece, and can effectively avoid the problem that it is not easy to take out the shaped cover piece during bending and shaping, resulting in a reduction in the bending and shaping efficiency of the bag cover piece.
