Technical Field

[0001] The utility model relates to the technical field of riveting and pressing, in particular to a riveting and pressing tool for a tubular part joint. Background Art

[0002] Tubular workpieces are widely used in various fields and can be used as protective covers, connecting structures or circulation channels, etc. In particular, as one of the components of the cable, the tubular workpiece needs to pass through the inside of the cable, and at the same time, such tubular workpieces need to be riveted with flexible joints to connect the tubular workpiece with other parts to form the whole cable. However, in the traditional riveting process, the inner hole of the flexible joint and the tubular workpiece at the riveting point may be out of round due to the large riveting force, resulting in increased movement resistance of the wire rope tube after the finished product is made. In the case of severe out of roundness, the wire rope cannot be inserted into the inner hole, and the processing quality is low. Utility Model Content

[0003] The utility model aims to solve the technical problems existing in the prior art, and particularly innovatively proposes a riveting tool for a tubular joint, which has a simple structure and can effectively prevent the inner hole of the tubular workpiece from deforming, thereby ensuring work quality.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a riveting tool for a tubular joint, including a riveting device, an upper die is arranged on the riveting device, a lower die is arranged directly below the upper die, and a cavity is concavely arranged on the bottom side of the upper die and the upper side of the lower die corresponding to the butt joint position of the tubular workpiece;

[0005] A mandrel for inserting into the tubular workpiece is provided on one side of the riveting device. The mandrel is equipped with a horizontally pushed-out cylinder. The outer diameter of the mandrel matches the inner diameter of the tubular workpiece, and when the cylinder is in an extended state, the end of the mandrel is located on the side of the docking position of the tubular workpiece away from the cylinder; and a starting switch for driving the cylinder and the riveting device is also included.

[0006] In the above scheme: the cylinder is equipped with an adjustment track, the adjustment track is parallel to the extension direction of the cylinder, the bottom of the cylinder is provided with an adjustment support, the adjustment support is slidably connected to the adjustment track, and the adjustment support is provided with a tightening bolt for fixing the adjustment support to the adjustment track. It can be adjusted according to different products, improve the scope of application, save costs, and ensure processing quality.

[0007] In the above scheme: the bottom of the adjustment support is provided with a slide groove matching the adjustment track, the bottoms of the front and rear sides of the adjustment support are extended downward to be flush with the bottom of the adjustment track, and the tightening bolt is arranged at the front side of the adjustment support. The adjustment support arranged as a straddle type can improve the adjustment stability and ensure the stability of the clamping.

[0008] In the above scheme: after the mandrel is inserted into the tubular workpiece, the distance between the end of the mandrel insertion end and the docking position is greater than 10 cm, thereby ensuring the insertion length of the mandrel and thus ensuring the processing quality.

[0009] In summary, the utility model has the following beneficial effects: simple structure and easy assembly. The provided mandrel can be inserted into the tubular workpiece to ensure the shape of the inner hole at the butt joint of the tubular workpiece, effectively prevent the inner hole of the tubular workpiece from being deformed, and ensure the processing quality. The provided upper die and lower die are used to position the tubular workpiece, and the provided riveting device is used to connect the butt joint positions of the tubular workpiece. BRIEF DESCRIPTION OF THE DRAWINGS
