Description

Technical Field

[0001] This utility model relates to the field of feeding for steel pipe processing, specifically a feeding device for cold-drawn seamless steel pipes. Background Technology

[0002] Cold-drawn precision seamless steel tubes are precision cold-drawn seamless tubes with high dimensional accuracy and good surface finish used in mechanical structures and hydraulic equipment. During cold drawing, the steel tube undergoes plastic deformation under the action of force through a mold of a certain shape and size. The drawing methods in production can be roughly divided into three types: diameter reduction drawing, outer wall reduction drawing, and inner wall reduction drawing. During cold drawing, the steel tube undergoes corresponding deformation under the action of tensile force, normal pressure, and friction. It mostly goes through three stages: diameter reduction, wall reduction, and sizing. Moreover, corresponding stresses are generated inside the deformation zone, of which the axial direction is tensile stress, and the radial and circumferential directions are compressive stress. During the drawing process, the metal is in a state of unidirectional tensile and bidirectional compressive stress. This is the basic mechanical characteristic of the cold-drawn tube deformation process. At present, when we perform cold drawing, we mostly use a crane to lift the tube blank and send it to the cold drawing machine for processing. However, using a crane for feeding has the following inconveniences: the crane response is slow, it is difficult to achieve rapid feeding, and the track occupies a lot of space. How to achieve convenient and efficient feeding is a technical problem that we urgently need to solve.

[0003] To address the aforementioned issues, we propose a feeding device for cold-drawn seamless steel pipes, which improves upon the shortcomings of existing technologies. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a feeding device for cold-drawn seamless steel pipes. In order to solve the above-mentioned technical problem, this utility model provides the following technical solution:

[0005] This utility model discloses a feeding device for cold-drawn seamless steel pipes, including a feeding hanger. A crossbeam is welded and fixed to the side of the top front of the feeding hanger. A feeding mechanism is provided on the crossbeam. The feeding mechanism includes a rotating column, a hanging plate, a sliding frame, a lifting motor, a feeding cylinder, a lifting rope, and a lifting beam. A vertical rotating column is welded to the end of the upper surface of the crossbeam. A rotatable hanging plate is provided on the rotating column. A sliding frame that can slide laterally along the hanging plate is provided. A lifting motor is fixed on the sliding frame. A winding wheel is also fixed on the output shaft of the lifting motor. A feeding cylinder is also fixed on the hanging plate. A lifting rope is wound on the winding wheel, and the bottom of the lifting rope is connected to the lifting beam.

[0006] Preferably, a bearing is embedded and fixed at the end of the hanging plate, and the bearing is sleeved on the rotating column.

[0007] Preferably, a throttle handle for rotating the suspended platform is fixed to the end of the suspended platform away from the lifting motor.

[0008] Preferably, a limiting ring is fitted and fixed on the rotating column, and the bearing is located above the limiting ring.

[0009] Preferably, hooks are fixed at both ends of the bottom of the lifting beam.

[0010] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0011] By installing a hanging plate on the feeding hanger for rotating the tube blank, and a sliding frame and feeding cylinder that can slide laterally on the hanging plate, and a lifting motor on the sliding frame, with a winding wheel on the lifting motor, the tube blank to be fed is lifted using the combination of the lifting motor, winding wheel, lifting rope and lifting beam. The flexibility of the lifting rope and the swing of the hanging plate can be used to rotate the tube blank to adjust its orientation. The feeding cylinder is used to push and pull the tube blank to adjust its position, thereby accurately delivering the tube blank to the cold drawing machine for processing. This feeding device for cold-drawn seamless steel pipes uses a small transverse structure to replace the traditional overhead crane for feeding. The feeding hanger spans one side of the material frame, occupying a small area, easy to move, flexible and convenient, and with a fast response speed, enabling rapid feeding, thus solving the defects of existing technology and improving practicality.

[0016] Example

[0017] like Figure 1As shown, a feeding device for cold-drawn seamless steel pipe includes a feeding hanger 1. A crossbeam 2 is welded and fixed to the side of the top front of the feeding hanger 1. A feeding mechanism is provided on the crossbeam 2. The feeding mechanism includes a rotating column 3, a hanging plate 4, a sliding frame 5, a lifting motor 6, a feeding cylinder 8, a lifting rope 9, and a lifting beam 10. An upright rotating column 3 is welded to the end of the upper surface of the crossbeam 2. A rotatable hanging plate 4 is provided on the rotating column 3. A sliding frame 5 that can slide laterally along the hanging plate 4 is provided on the hanging plate 4. A lifting motor 6 is fixed on the moving frame 5, and a winding wheel 7 is also fixed on the output shaft of the lifting motor 6. A feeding cylinder 8 is also fixed on the hanging plate 4. A hanging rope 9 is wound on the winding wheel 7, and a hanging beam 10 is connected to the bottom of the hanging rope 9. This forms an integral feeding device structure for cold-drawn seamless steel pipes. The feeding hanger 1 spans one side of the material frame, which occupies a small area, is easy to move, flexible and convenient, and has a fast response speed, enabling rapid feeding. This solves the defects of existing technology and improves practicality.

[0018] In this embodiment, a bearing 12 is embedded and fixed at the end of the hanging plate 4, and the bearing 12 is sleeved on the rotating column 3, which facilitates the fixing of the hanging plate 4 and also allows it to rotate.

[0019] In this embodiment, a handle 11 for rotating the hanging plate 4 is also fixed on the end of the hanging plate 4 away from the lifting motor 6, which is used to rotate the steel pipe.

[0020] In this embodiment, a limiting ring 13 is sleeved and fixed on the rotating column 3, and the bearing 12 is located above the limiting ring 13 to support the bearing 12 and prevent it from sliding down.

[0021] In this embodiment, hooks 14 are fixed at both ends of the bottom of the lifting beam 10 for hanging the binding rope to lift the steel pipe.

[0022] The principle and advantages of this utility model are as follows: The feeding hanger 1 of the device is placed on one side of the material frame to send the steel pipe in the material frame to the machine for cold drawing. Then, the lifting motor 6 and the feeding cylinder 8 are connected to the power supply to power the device. When feeding, the binding rope is hung on the two hooks 14 to hang the steel pipe and feed it. The worker holds the handle at the end of the throttle 11 with both hands and rotates the hanging plate 4 so that the hanging plate 4 is aligned with the steel pipe on the material frame. Then, the lifting motor 6 is turned on to release the rope, so that the lifting beam 10 is lowered above the steel pipe. Then, the feeding cylinder 8 is turned on to extend and retract, further adjusting the position of the binding rope. Then, the binding rope is hung on both ends of the steel pipe, the lifting motor 6 is turned on to lift the steel pipe, and the hanging plate 4 is swung to coordinate with the extension and retraction of the feeding cylinder 8 to quickly and accurately send the steel pipe to the feeding position of the cold drawing machine. The feeding hanger 1 is straddling one side of the material frame, which occupies a small area, is easy to move, flexible and convenient, and has a fast response speed, which can realize rapid feeding, thereby solving the defects of the existing technology and improving practicality.
