[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] Example 1
[0019] like Figure 1-3 As shown, the utility model provides a technical solution: a multi-station nut cold heading machine, including a nut cold heading machine body 1, a conveying assembly 2 is fixed on one side of the nut cold heading machine body 1, and the nut cold heading machine body 1 and the conveying assembly 2 are both provided with a pumping port, the conveying assembly 2 includes a rotating plate and a movable correction wheel, when the nut cold heading machine body 1 extracts the steel wire, the bent steel wire is corrected to make it straight through the conveying assembly 2, which is convenient for the subsequent processing of the steel wire by the nut cold heading machine body 1, a connecting plate 5 is fixed on one side of the nut cold heading machine body 1, and the connecting plate 5 A motor 6 is fixed on the surface, and a fixed disc 7 is fixed on the output shaft of the motor 6, and a through hole is opened on the fixed disc 7. The motor 6 controls the rotation of the fixed disc 7, and the rotation of the fixed disc 7 will eventually drive the rotation of the movable placing plate 12. The movable placing plate 12 carries the wire coil to rotate, which provides convenience for the nut cold heading machine body 1 to extract the wire. A sleeve 8 is fixed on the lower surface of the fixed disc 7 at the through hole. The setting of the sleeve 8 leaves enough space for the subsequent contraction of the spring 13, and a fixing rod 9 is fixed on the sleeve 8. The fixing rod 9 It plays the role of positioning the wire coil placed on the movable placement plate 12, and also ensures the stability of the movable placement plate 12 and the spring 13 when they are moving. One end of the fixing rod 9 is threadedly connected with an assembly part 10. The setting of the assembly part 10 facilitates the disassembly of the limit plate 11 on the fixing rod 9 to prevent the limit plate 11 from hindering the placement of the wire coil. The limit plate 11 is fixed on one side of the assembly part 10. The height of the limit plate 11 is consistent with the pumping port. At the same time, the limit plate 11 blocks the upward movement of the wire coil to prevent it from excessive movement. A movable placing plate 12 is slidably connected to the surface of the fixed rod 9. The movable placing plate 12 is used to place the steel wire coil, and a spring 13 is sleeved on the fixed rod 9. One end of the spring 13 is fixedly connected to the sleeve 8, and the other end is fixedly connected to the movable placing plate 12 through the hole. When the steel wire coil is extracted and its height is reduced to leave a gap between it and the limit plate 11, with the help of the spring 13, the movable placing plate 12 is moved upward to fill the gap between the steel wire coil and the limit plate 11, thereby reducing the bending of the steel wire during the pumping process and reducing the resistance to pumping.
[0020] Example 2
[0021] like Figure 1-3As shown, a positioning member 3 is fixed on one side of the conveying component 2. The positioning member 3 plays a role in positioning the steel wire at one end of the conveying component 2 to improve the stability of the steel wire when being pumped. A rolling ball 4 is rotatably connected to the perforation of the positioning member 3, and the number of rolling balls 4 is set to be several. With the help of the rolling balls 4, the resistance of the steel wire passing through the positioning member 3 is reduced, which is beneficial to the pumping of the steel wire. A plug column 14 is connected through the side plate on the fixed disc 7, and the plug column 14 is engaged with the movable placement plate 12. The plug column 14 plays a role in positioning the movable placement plate 12 to avoid the movable placement plate 12 from moving randomly under the influence of the spring 13 when placing the steel wire coil, thereby affecting the normal placement of the steel wire coil. A movable limiting plate 15 is fixedly connected to the outer surface of the plug column 14, and the number of movable limiting plates 15 is set to two. The movable limiting plate 15 plays a role in limiting the movement of the plug column 14 to avoid it from detaching from the side plate of the fixed disc 7 to prevent it from being lost.
[0022] Working principle:
[0023] like Figure 1-3 As shown, when the utility model is in use, the user first sleeves the steel wire coil on the fixing rod 9 and places it on the movable placement plate 12, then rotates and fixes the assembly 10 on one end of the fixing rod 9, and then pulls out the plug 14 to disconnect it from the movable placement plate 12. At this time, the movable placement plate 12 is affected by the contracted spring 13 in the sleeve 8, and carries the steel wire coil to move upward along the fixing rod 9 until the steel wire coil contacts the limit plate 11 and stops moving.
[0024] Then, hold one end of the steel wire and let it pass through the positioning piece 3, and then pass through the extraction port of the nut cold heading machine body 1 and the conveying assembly 2, and send one end of the steel wire to the inside of the nut cold heading machine body 1, and then control the nut cold heading machine body 1 to extract the steel wire. At the same time, it is also necessary to start the motor 6. The motor 6 will drive the fixed disc 7 and the movable placing plate 12 to rotate slowly, so that the steel wire coil also starts to rotate, which is convenient for the extraction of the steel wire. When the height of the steel wire coil is extracted and the gap is left between it and the limit plate 11, with the help of the spring 13, the movable placing plate 12 is moved upward to fill the gap between the steel wire coil and the limit plate 11, thereby reducing the bending of the steel wire during the extraction process and reducing the resistance to extraction.
