Description

Technical Field

[0001] The utility model relates to the technical field of bending processing equipment, in particular to a bending machine capable of automatically adjusting bending balance. Background Art

[0002] In the process of carton packaging processing, it is usually necessary to use a blade of a specified shape to cut the paper into a specified shape and then fold it into a carton. The blade in the processing process often needs to be bent to form the specified shape. The emergence of bending machines can efficiently bend steel blades.

[0003] Existing bending machines for such blades are usually provided with a bending inner mold and a bending outer mold sleeved outside the bending inner mold. Both the bending inner mold and the bending outer mold are provided with bending channels. The blade passes through the bending channels of the bending inner mold and the bending outer mold. The bending outer mold can rotate relative to the bending inner mold, and the bending inner mold is locked on the bending mounting seat.

[0004] Since the upper and lower ends of the blade are the cutting edge at one end and the handle at the other end, it is easy for uneven force to occur in the bending process, resulting in imbalance or warping at both ends. In order to avoid this problem, the existing method is to set an air avoidance gap on the bending channel of the bending inner mold. By adjusting the amount of the handle end of the blade in the air avoidance gap, the blade can be balanced, reducing the imbalance of force at both ends and the occurrence of warping, which affects the subsequent shearing process.

[0005] The existing tool handle is no longer adjusted to avoid the size of the gap. Instead, the method is to loosen the bending inner mold, adjust the rise or fall of the bending inner mold, and then lock the bending inner mold on the bending mounting seat. The whole process is relatively auxiliary, and the manual adjustment efficiency is low, which affects the entire processing process and is not conducive to improving the competitiveness of the enterprise.

[0025] like Figure 1-3 As shown, the utility model is a bending machine that automatically adjusts the bending balance, including a bending machine body 1, on which a lifting assembly, a feeding mechanism 2 and a bending assembly are provided.

[0026] By setting the lifting component, the bending mounting seat 4 can be efficiently driven to move linearly, and the relative position of the material to be processed and the bending component can be automatically adjusted according to demand, thereby avoiding the situation where the blade bends and warps.

[0027] The bending motor 3 is fixedly arranged on the bending machine body 1 , and the upper and lower ends of the bending outer die 6 are respectively a rotating connection end 61 and a rotating drive end 62 . The rotating connection end 61 at the upper end of the bending outer die 6 is rotatably connected to the bending mounting seat 4 .

[0028] Through the arrangement of the bending motor 3 , the moving end of the bending motor 3 can cooperate with the rotating driving end 62 to drive the bending outer die 6 to rotate relative to the bending mounting seat 4 to perform the bending action.

[0029] The lifting assembly includes a lifting screw 7 and a lifting drive assembly. A driving threaded seat 41 that cooperates with the lifting screw 7 is provided on the bending mounting seat 4. A screw mounting limit seat 101 that cooperates with the lower end of the lifting screw 7 is provided on the bending machine body 1. The moving end of the lifting drive assembly is connected to the upper end of the lifting screw 7.

[0030] By means of transmission via the lifting screw 7 , the movement of the bending mounting seat 4 can be made more stable, and the lifting screw 7 can be driven to rotate.

[0031] The lifting drive assembly includes a pulley assembly 8 and a lifting drive motor 9. One end of the pulley assembly 8 is sleeved on the lifting screw rod 7, and the other end of the pulley assembly 8 is sleeved on the moving end of the lifting drive motor 9.

[0032] The bending machine body 1 is provided with a lifting slide rail 102 that cooperates with the bending mounting seat 4 , and the bending mounting seat 4 is provided with a lifting slider that cooperates with the lifting slide rail 102 . The bending mounting seat 4 is slidably connected to the lifting slide rail 102 .

[0034] The bending machine body 1 is provided with a lifting limit groove 103, which is arranged on the side of the lifting slide rail 102. The bending mounting seat 4 is provided with a limiting protrusion that cooperates with the lifting limit groove 103, and the limiting protrusion is arranged in the lifting limit groove 103.

[0035] By providing the lifting limit groove 103 , the movement range of the bending machine body 1 can be further limited, effectively preventing the bending mounting seat 4 from falling off the lifting slide rail 102 .

[0036] The bending inner mold 5 includes an installation and positioning part and a processing part. A bending channel 51 is provided in the processing part, and a bending air avoidance gap 511 is provided on the bending channel 51. A limiting plane 52 is provided on the installation and positioning part. The limiting plane 52 can prevent the bending inner mold 5 from rotating relative to the bending mounting seat 4.

[0037] By setting the lifting assembly, the bending mounting seat 4 is controlled to rise and fall, thereby adjusting the amount of the tool handle end in the bending avoidance gap 511 to avoid imbalance or warping of the two ends of the bend.

[0038] The bending mounting seat 4 is also provided with an inner mold fixing seat 10 and an inner mold locking block.

[0042] By setting the avoidance step 64 , the bending angle range can be effectively expanded, and position restriction between the bending blade and the bending outer mold 6 caused by a small bending angle can be avoided.

[0043] The bending main machine is also provided with a bending limit block 11 , and the side of the bending limit block 11 facing the bending outer die 6 is provided with a contouring surface.

[0044] By setting the bending limit block 11, the movement deviation of the bending outer mold 6 can be effectively prevented.

[0045] The working process of the bending machine for automatically adjusting the bending balance provided in this embodiment is as follows: Compared with the existing processing method, the embodiment of the utility model provides the advantages of higher adjustment efficiency and high adjustment accuracy.

[0046] First, the feeding mechanism 2 transports the blade to the bending assembly, and the blade to be processed passes through the bending channel 51 and the bending notch 63, so that the blade to be processed penetrates the bending inner mold 5 and the bending outer mold 6.

[0047] Before processing, the number of the bending gaps 511 of the handle end of the blade to be processed is adjusted according to different processing requirements of the blade to be processed.

[0048] The lifting drive assembly drives the lifting screw 7 to rotate, and the lifting screw 7 drives the bending mounting seat 4 to lift and lower, so that the bending inner mold 5 and the bending outer mold 6 are lifted and lowered together, so that the bending inner mold 5 and the bending outer mold 6 move relative to the blade to be processed, and the processing blade moves in the bending channel 51.

[0049] This enables efficient and high-precision regulation.

[0050] After the adjustment is completed, the bending motor 3 drives the bending outer mold 6 to rotate to realize the bending process of the blade to be processed.

[0051] From the above, it can be seen that the beneficial effect of the utility model is: the use of its mechanism can effectively solve the problem of low adjustment efficiency and low adjustment accuracy of the bending machine in the prior art through manual adjustment. By using this product structure, the lifting component can efficiently control the linear movement of the bending mounting seat 4, so that the blade to be processed on the feeding mechanism 2 and the bending inner mold 5 move relative to each other, realizing the effect of automatic adjustment, improving the adjustment efficiency and adjustment accuracy, and helping to improve the competitiveness of the enterprise.
