Description

Technical Field

[0001] The utility model belongs to the technical field of bending machines, and in particular relates to an adjustable limiting structure of a bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates.

[0019] In order to make the purpose, technical solution and advantages of the present invention more clear, the following is a detailed description of the present invention in conjunction with the specific implementation methods and with reference to the attached drawings. Figure 1-4 , the utility model is further described in detail. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0020] The utility model provides an adjustable limit structure of a bending machine, comprising a hard rail bracket 10, a limit plate 11 is installed on one side of the hard rail bracket 10, and the limit plate 11 is installed on the upper mold 2. An adjustment plate 9 is installed on the other side of the hard rail bracket 10, and an adjustment block 13 is movably installed on the inner side of the adjustment plate 9 through an adjustment component, and the adjustment component includes an adjustment plate seat 7 installed on both sides of the adjustment plate 9, and an adjustment hole is provided on the adjustment plate seat 7, and the adjustment hole is elliptical, and a locking bolt 6 connected to the adjustment block is provided on the adjustment hole, and a plurality of tightening bolts 8 are vertically provided on the adjustment plate 9, and the inner part of the tightening bolt 8 passes through the adjustment plate 9 and abuts against the outer side of the adjustment block 13. When the slider 14 becomes loose after long-term use, the locking bolt 6 is loosened, the adjusting block 13 is slid inward, the locking bolt 6 is tightened, and then the plurality of tightening bolts 8 are rotated so that the inside of the tightening bolt 8 abuts against the adjusting block 13, which plays a supporting role during sliding, prevents the adjusting block from deforming, and improves resistance and prolongs service life.

[0021] A wear-resistant plate 12 is disposed inside the adjustment block 13 , and a wear-resistant plate 12 is disposed inside the limit plate 11 . The wear-resistant plate 12 is made of copper to improve wear resistance. A slider is disposed between the two wear-resistant plates 12 , and the slider 14 is mounted on the frame 1 .

[0022] The slider 14 is hollow and provided with a lubricating oil cavity. The upper end of the slider 14 is provided with an oil inlet 15 connected to the lubricating oil cavity. The two sides of the slider 14 are provided with oil outlets at the contact points with the wear-resistant plate 12. The lubricating oil cavity is filled with lubricating oil. As the limiting structure moves vertically on the slider 14, the lubricating oil in the lubricating oil cavity is discharged from the oil outlet, which plays a role in lubrication, reduces the friction between the wear-resistant plate 12 and the slider, and prolongs the service life.

[0023] The lower part of the throat of the frame 1 is fixedly connected to the support plate 16, and a gap is left between the support plate 16 and the frame. The upper end of the support plate 16 is installed with a limit grating ruler 4, and the grating reading head 3 of the limit grating ruler 4 is arranged on the upper mold. As the upper mold of the bending machine moves downward, a large pressure is generated on the frame 1, so the upper end of the throat of the frame 1 will deform downward, which makes it difficult to grasp the pressure of the stamping. However, the utility model uses an additional support plate 16, which does not deform with the deformation of the frame 1, and can always read accurately, thereby ensuring that the process of pressing is accurately grasped and the bending angle can be effectively controlled.

[0024] The utility model provides a movable adjusting block. After long-term use, the position of the adjusting block is moved to always maintain the limiting effect on the sliding block to prevent derailment. A lubricating oil cavity is provided to play a lubricating role during sliding. The utility model has a simple structure, is easy to use and has a prolonged service life.
