Description

Technical Field

[0001] The utility model belongs to the technical field of straightening and bending, and in particular relates to a straightening and bending device for an anti-falling guide rail. Background Art

[0002] Among the methods for straightening workpieces, the reverse bending straightening method is one of the most commonly used methods. Its straightening principle is based on the theory of elastic-plastic deformation, and the workpiece is straightened in a cold state. The working principle is to support the workpiece with the original bend between two movable support points of the workbench and use the pressure head to align the most curved part to perform reverse bending. This method causes the workpiece to produce plastic deformation, thereby achieving the purpose of straightening.

[0003] After searching, a document with publication number (CN203936169U) discloses a device for controlling the bending amount of a workpiece of a straightening machine, including an upper pressure block, a lower pressure block, a feed block, a spring and a baffle. The upper pressure block is pressed on the lower pressure block and slides with the upper surface of the lower pressure block. The feed block is located on one side of the lower pressure block and slides with the lower pressure block. The baffle is located on the other side of the lower pressure block. One end of the spring is pressed on the baffle, and the other end of the spring is pressed on the lower pressure block.

[0004] The above device is realized through the straightening machine workpiece bending amount control device. The pressure measuring component is mainly used to detect whether the bending amount of the shaft rod workpiece reaches a given value when the pressure head is pressed down. For the hydraulically driven pressure head, it can also be judged whether the bending amount reaches a given value by detecting the change in pressure.

[0005] In actual use, the above device punches the workpiece through the cooperation between the pressure block and the spring and other components. However, in the actual punching operation, the workpiece cannot be limited, resulting in the workpiece easily slipping out of the device during punching.

[0006] In view of this, the present utility model is proposed. Utility Model Content
