[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.
[0020] Refer to Figures 1-3, A wire feeding mechanism for spring production, including an aggregation hopper 2. At the center position of the top of the aggregation hopper 2, a load-carrying disk 6 is rotatably connected. At the top of the load-carrying disk 6, guide posts 5 are circularly arrayed. At the bottom edge position of the aggregation hopper 2, a dirt discharge pipe 7 is fixedly arranged, and the dirt discharge pipe 7 is used for the aggregation and recovery of the oxide layer fragments inside the aggregation hopper 2.
[0021] At the bottom of the side of the aggregation hopper 2, a horizontal U-shaped frame 4 is vertically fixedly arranged. At the end of the top of the horizontal U-shaped frame 4, a guide wheel 3 is rotatably connected. On the side of the horizontal U-shaped frame 4 and the guide wheel 3, a scaling component for scaling wire with different diameters is arranged. Between the inner cavity of the aggregation hopper 2 and the load-carrying disk 6, an aggregation arc block 1 is slidably arranged. At the middle position of the top of the aggregation arc block 1, a protrusion is fixedly arranged, and the protrusion facilitates the worker to take the aggregation arc block 1 and move it along the bottom of the inner cavity of the aggregation hopper 2, moving the oxide layer fragments scattered everywhere at the bottom of the inner cavity of the aggregation hopper 2 to near the dirt discharge pipe 7.
[0022] The scaling component includes a scaling cylinder 8, a common disk 10, and a positioning column 11. The center position on the side of the common disk 10 is fixedly connected to one end of the positioning column 11. The positioning column 11 is rotatably connected to the side of the horizontal U-shaped frame 4. On the side of the common disk 10, scaling cylinders 8 are circularly arrayed. Scaling holes 9 are opened on the side of the scaling cylinder 8. The diameters of the scaling holes 9 of multiple groups of scaling cylinders 8 gradually decrease in diameter in the counterclockwise direction, and the diameter of the scaling holes 9 is set to select the diameter of the common spring raw material steel wire rod.
[0023] On the outer wall of one end of the side of the positioning column 11 on the horizontal U-shaped frame 4, positioning grooves 12 are circularly arrayed. A limit block 15 is movably inserted into any one of the positioning grooves 12. The top of the limit block 15 is fixedly connected to one end of a lifting handle 13. The lifting handle 13 is movably inserted into a fixed block 14, and the fixed block 14 is fixedly connected to the top of the side of the horizontal U-shaped frame 4. When the limit block 15 is inserted into any one of the positioning grooves 12, any one of the scaling cylinders 8 on the common disk 10 is limited on the side of the guide wheel 3.
[0024] The specific implementation steps and principles of the present utility model are as follows:
[0025] According to the actual diameter of the steel coil wire, the limit block 15 is disengaged from any one of the positioning grooves 12, and the scaling cylinder 8 with a scaling hole 9 of an appropriate diameter is rotated to one side of the guide wheel 3, and then the limit block 15 is lowered. The limit block 15 is inserted into the positioning groove 12 to limit the rotation of the common disk 10. The worker places the steel wire coil between multiple groups of guide posts 5, and one end of the steel wire coil passes through the scaling cylinder 8 and the guide wheel 3 in sequence and is finally introduced into the forming machine. The scaling cylinder 8 scrapes the oxide layer fragments remaining on the outer wall of the steel wire coil into the aggregation hopper 2.
[0026] When it is necessary to clean the oxide layer fragments, a recovery bag is sleeved at the end of the dirt discharge pipe 7. The worker continuously pushes the aggregation arc block 1 along the inner cavity of the aggregation hopper 2. The aggregation arc block 1 pushes the oxide layer fragments into the dirt discharge pipe 7, and the oxide layer fragments are finally discharged from the dirt discharge pipe 7.
[0027] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and inventive concept of the present utility model, making equivalent replacements or changes should be covered within the protection scope of the present utility model.
