[0002] During the steel production process, the steel needs to be forged to improve its quality. When forging steel, in order to make the forging of steel more convenient, people usually use a workpiece positioning device to assist the forging of steel. However, there are many positioning methods currently used for steel forging, including manually holding clamps to adjust the position of the steel, and using cylinders to control the hydraulic jaws for extension and retraction. The above clamping and positioning methods are relatively traditional and have certain defects. First, the manual method increases the labor intensity and is not conducive to mechanized production; secondly, although the cylinder-controlled hydraulic jaws for extension and retraction positioning can achieve automatic control, it is difficult to achieve the flipping forging of steel.

[0013] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0014] The utility model proposes a workpiece positioning device for steel forging, comprising a box body 1, a cylinder 2 and a hydraulic clamp 3. The cylinder 2 is installed in a through-type manner on the side wall of the box body 1. The cylinder 2 can drive the hydraulic clamp 3 to extend and retract. The hydraulic clamp 3 can clamp and fix the workpiece, and then the workpiece is driven to move and position on the forging table of the forging machine through the operation of the cylinder 2. A sleeve 4 is rotatably connected on the side wall of the box body 1 corresponding to the cylinder 2. A driving component is arranged on the sleeve 4. The driving component can control the sleeve 4 to rotate, and a spline shaft 5 is connected to the inner cavity key of the sleeve 4. The movable end of the cylinder 2 is rotatably connected to the spline shaft 5 through a connecting sleeve 6. The other end of the spline shaft 5 is fixedly connected to the hydraulic clamp 3. The purpose of this connection is that while the cylinder 2 can drive the spline shaft 5 to move laterally, the sleeve 4 can also drive the spline shaft 5 to rotate, thereby driving the hydraulic clamp 3 and the workpiece flipping angle. The spline shaft 5 and the hydraulic clamp 3 are reinforced by arranging a fixing plate 15. Since the volume of the hydraulic clamp 3 is large, this design can increase its connection stability.

[0015] Specifically, the driving component includes a motor 7, which is installed at the bottom of the outer wall of the box body 1. The output end of the motor 7 is connected to a reducer 8, which is installed on the outer wall of the box body 1. When the motor 7 is working, the rotation speed can be reduced at the reducer 8. The output end of the reducer 8 is movable and runs through the outer wall of the box body 1, and a driving wheel 9 is fixedly connected to the output end of the reducer 8. The reducer 8 can provide power to the driving wheel 9. A driven wheel 10 is meshed on one side of the driving wheel 9, and the driven wheel 10 is sleeved on the outer wall of the sleeve 4. The rotating driving wheel 9 can drive the sleeve 4 to rotate by meshing with the driven wheel 10, thereby providing power for the rotation of the sleeve 4.

[0016] Specifically, a mounting base 11 is provided under the box body 1, and the mounting base 11 and the box body 1 are connected by a hydraulic cylinder 12. The mounting base 11 can be fixed to the ground by bolts, and the design of the hydraulic cylinder 12 can make the height of the workpiece match that of the forging table.

[0017] Specifically, a bracket 14 is fixedly provided on the outer wall of the box body 1 at the bottom of the cylinder 2 , and the bracket 14 can support the cylinder 2 .

[0018] Specifically, a PLC controller 13 is installed on the outer wall of the box body 1, and the PLC controller 13 is electrically connected to the cylinder 2, the hydraulic clamp 3, the motor 7 and the hydraulic cylinder 12 respectively. The PLC controller 13 can realize synchronous control of the cylinder 2, the hydraulic clamp 3, the motor 7 and the hydraulic cylinder 12.

[0019] Specifically, the hydraulic clamp 3 can be started to clamp the workpiece, and then the hydraulic cylinder 12 can be driven according to the thickness of the workpiece, so that the height of the workpiece matches the forging table of the forging machine, and then the cylinder 2 is started. Under the operation of the cylinder 2, the hydraulic clamp 3 can be driven to move to the forging table through the spline shaft 5, and then the workpiece is driven to move to the forging table for positioning and forging. When the workpiece needs to be flipped for forging, the motor 7 can be started. Under the operation of the motor 7, the speed can be reduced at the reducer 8, and power can be provided to the driving wheel 9. At the same time, the driving wheel 9 can drive the sleeve 4 to rotate by meshing with the driven wheel 10. Since the sleeve 4 and the spline shaft 5 are splined, the spline shaft 5, the hydraulic clamp 3 and the workpiece can be flipped, and the flipping angle can be controlled at will. In summary, the positioning device replaces the manual clamp positioning, and is upgraded and transformed on the basis of the cylinder 2 controlling the extension and retraction of the hydraulic clamp 3, so that the positioning device has diversity.

The models are compatible with this solution and can operate normally. All the electrical parts in this case are connected to the power supply adapted to them through wires, and according to the actual situation, a suitable PLC controller is selected to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection is completed in the working order of each electrical component. The detailed connection means are well-known technologies in this field and will not be explained in the electrical control.

[0021] Working principle: When it is necessary to forge steel, the hydraulic clamp 3 can be started to clamp the workpiece, and then the hydraulic cylinder 12 can be driven according to the thickness of the workpiece, so that the height of the workpiece matches the forging table of the forging machine, and then the cylinder 2 is started. Under the operation of the cylinder 2, the hydraulic clamp 3 can be driven to move to the forging table through the spline shaft 5, and then the workpiece is driven to move to the forging table for positioning forging. When it is necessary to flip the workpiece for forging, the motor 7 can be started. Under the operation of the motor 7, the speed can be reduced at the reducer 8, and power can be provided to the driving wheel 9. At the same time, the driving wheel 9 can drive the sleeve 4 to rotate through the engagement with the driven wheel 10. Since the sleeve 4 and the spline shaft 5 are splined, the spline shaft 5, the hydraulic clamp 3 and the workpiece can be flipped, and the flipping angle can be controlled at will. In summary, the positioning device replaces the manual clamp positioning, and is upgraded and transformed on the basis of the cylinder 2 controlling the extension and retraction of the hydraulic clamp 3, so that the positioning device has diversity.
