Description

Technical Field

[0001] This utility model belongs to the field of stamping die processing technology, specifically relating to a large-angle rapid bending die. Background Technology

[0002] Currently, stamping is generally carried out at room temperature using the pressure of a press. The reciprocating motion of the stamping die causes the upper and lower dies of the stamping die to punch and shape the product to be processed, so as to achieve the required size and shape of the part.

[0003] Bending dies are a sub-type of stamping dies, specifically used to bend and deform workpieces. Through the cooperation of the punch (upper die) and die (lower die) of the die, flat material is bent into parts with specific angles (such as 90°, U-shape, V-shape, etc.) or curved shapes. However, traditional bending dies cannot achieve large-angle bending in one step, requiring two bending to press into a large angle. Moreover, the workpiece is very difficult to remove after bending, which means that the operator needs to manually use tools such as hammers to knock out the formed workpiece. This is labor-intensive and has low work efficiency. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-6 As shown, this utility model provides a technical solution: a large-angle rapid bending die, including an upper die assembly and a lower die assembly. The upper die assembly feeds to the lower die assembly to achieve bending. An automatic demolding and unloading mechanism is provided between the upper die assembly and the lower die assembly. The automatic demolding and unloading mechanism includes a demolding template 1, a push plate 2, and a push cylinder 3. The demolding template 1 is horizontally arranged between the upper die assembly and the lower die assembly. The output end of the push cylinder 3 is connected to the push plate 2. The push plate 2 moves along the length direction of the lower die assembly.

[0017] like Figure 2 As shown, the upper mold assembly includes an upper mold frame 4, a bending cylinder 5, and a bending upper mold 6. The upper mold frame 4 is fixed above the stripping template 1. The bending cylinder 5 is located on the top of the upper mold frame 4, and the output end of the bending cylinder 5 is connected to the bending upper mold 6. The bending upper mold 6 is located between the upper mold frame 4 and the stripping template 1.

[0018] The demolding template 1 is provided with a demolding hole. The bending upper die 6 passes vertically through the demolding hole. The bending cylinder 5 drives the bending upper die 6 to enter and exit the demolding hole to remove the formed workpiece from the bending upper die 6, thereby realizing the automatic demolding of the formed workpiece.

[0019] like Figure 3 As shown, the lower die assembly includes a base 7, a lower bending die 8, a support plate 9, and a support frame 10. The support plate 9 and the support frame 10 are symmetrically fixed at both ends of the top of the base 7. The ends of the support plate 9 and the support frame 10 away from the base 7 are connected to the demolding template 1. The lower bending die 8 is located at the middle of the top of the base 7, and a bending die groove is provided on the top of the lower bending die 8. The upper bending die 6 passes through the demolding hole and is inserted into the bending die groove on the top of the lower bending die 8.

[0020] The demolding hole is positioned corresponding to the bending die groove, so that the formed workpiece removed from the upper bending die 6 can fall into the bending die groove.

[0021] like Figure 1 As shown, the pusher cylinder 3 is fixed on the support plate 9, the pusher plate 2 is located on one side of the bending lower die 8, and the shape of the pusher plate 2 matches the bending die groove. The pusher cylinder 3 can drive the pusher plate 2 to move along the bending die groove, thereby pushing the detached forming workpiece to the guide plate 14, and thus realizing the automatic unloading of the forming workpiece.

[0022] like Figure 3 and 4 As shown, guide rods 11 are provided on both sides of the support plate 9 and the support frame 10 near the demolding template 1, and sliding sleeves 12 are fitted on the guide rods 11. The top of the push plate 2 is connected to the two sliding sleeves 12 respectively through the V-shaped frame 13. The guide rods 11 provide guidance and limit for the movement of the push plate 2, ensuring the stability of the movement of the push plate 2.

[0023] like Figure 1 , 5 As shown in Figure 6, a guide plate 14 is provided at the end of the lower bending die 8 away from the push plate 2. A T-shaped slider is provided at the end of the guide plate 14 near the lower bending die 8, and a T-shaped groove matching the T-shaped slider is opened at one end of the lower bending die 8. The highest point of the guide plate 14 and the lowest point of the bending die groove are on the same straight line, so that the formed workpiece is directly discharged from the guide plate 14 after being pushed out of the bending die groove.

[0024] The working principle and usage process of this utility model are as follows: During use, the bending cylinder 5 drives the upper bending die 6 to move downwards and insert it into the bending die groove of the lower bending die 8 through the demolding hole, thereby bending the workpiece. After bending, the bending cylinder 5 retracts, driving the upper bending die 6 to move upwards. The upward movement of the upper bending die 6 causes the formed workpiece to leave the bending die groove together. The upward movement of the upper bending die 6 and its cooperation with the demolding hole separate the formed workpiece from the upper bending die 6. The separated formed workpiece falls into the bending die groove. Then, the pusher cylinder 3 drives the pusher plate 2 to enter and move along the bending die groove, thereby pushing the formed workpiece out of the bending die groove. After leaving the bending die groove, the formed workpiece reaches the guide plate 14 and is discharged by the guide plate 14. This realizes automatic demolding and automatic unloading of the formed workpiece, improving processing efficiency.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
