Description

Technical Field

[0001] The utility model relates to the technical field of cold heading machines, and particularly relates to a cold heading machine for fastener forming. Background Art

[0002] A cold heading machine is a special equipment used for stamping in mechanical manufacturing. It can process raw materials into required shapes at normal temperature through the principle of metal plastic forming, such as bolts, nuts, screws, rivets, etc.

[0003] A cold heading machine uses a punch and a die to plastically deform or separate a blank, thereby realizing forming processing. For example, the Chinese utility model patent with the publication number CN219817920U: A device for preventing material ejection of a cold heading machine. This application includes a cold heading machine. An inlet component is arranged on the front side of the cold heading machine. The inlet component includes two upper inlet wheels and a lower inlet wheel. A blank is conveyed between the upper inlet wheel and the lower inlet wheel. A non-return component is arranged between the inlet component and the cold heading machine. The non-return component includes an L-shaped plate fixedly arranged on the side wall of the cold heading machine. A lower pressing seat is fixedly arranged at the upper end of the horizontal plate of the L-shaped plate. A guiding component is arranged between the lower pressing seat and the inlet component. The guiding component includes a guiding tube fixedly arranged on the side wall of the cold heading machine. The inlet of the guiding tube is on one side of the inlet component, and the outlet of the guiding tube is on one side of the lower pressing seat. The guiding tube is fixedly arranged on the cold heading machine through a fixing component. That is, by setting the guiding tube, it plays a guiding and supporting role when the blank enters the cold heading machine, so that the blank can enter from the inlet of the guiding tube after entering from the inlet component. However, when a wire coil feeding rack feeds wire into the cold heading machine, factors such as tension control and speed adjustment during the feeding process may also cause the wire to have a slight deviation or rotation during transportation, and the wire on the wire coil will have an up-and-down reciprocating movement because it is wound on the wire coil feeder, thereby changing its input angle. When the angle of the wire input into the cold heading machine becomes larger, the wire may not be able to smoothly enter the mold or the guiding device, resulting in material jamming or blockage. Content of the Utility Model

[0004] The purpose of the utility model is to provide a cold heading machine for fastener forming, which can effectively solve the problems in the background art that when the wire is input into the cold heading machine through the wire guiding component, due to reasons such as wire feeding tension and wire output height, the angle of the wire input into the cold heading machine continuously changes, resulting in continuous friction between the wire and the guiding component, causing equipment wear and material jamming.

A control box 3 is fixedly installed on the front side of the cold heading machine body 1. A feeding seat 4 is arranged on one side of the cold heading machine body 1. A first fixed flange 5 is fixedly installed on one side of the feeding seat 4, and the feeding seat 4 is fixedly installed on the wire input mechanism of the cold heading machine body 1 through the first fixed flange 5. A guiding mechanism 6 is arranged on the feeding seat 4. The guiding mechanism 6 includes a top seat 7. An upper mounting block 8 and a lower mounting block 9 are fixedly installed on the top seat 7. A cantilever 10 is fixedly installed between the upper mounting block 8 and the lower mounting block 9. A plurality of suspension seats 11 are movably installed at the bottom of the cantilever 10. A guiding seat 12 is movably installed at the bottom of the suspension seat 11.

[0033] A second fixed flange 13 is fixedly installed at the bottom of the top seat 7, and the top seat 7 is of a C-shaped structure. The second fixed flange 13 is inserted and installed outside the feeding seat 4 and fixedly installed on one side of the first fixed flange 5. Based on this, through the setting of the top seat 7 and the second fixed flange 13, and in cooperation with the upper mounting block 8 and the lower mounting block 9, installation conditions can be provided for the cantilever 10. Slots 15 are respectively formed on the opposite sides of the upper mounting block 8 and the lower mounting block 9. Side blocks 14 are respectively fixedly installed on both sides of the upper mounting block 8 and the lower mounting block 9. The upper mounting block 8 and the lower mounting block 9 are respectively inserted and installed on the horizontal part of the top seat 7 through the slots 15 on the opposite sides, and the adjacent two side blocks 14 are fixedly connected by bolts. Two reinforcing ribs 16 are fixedly installed at the top of the cantilever 10. A chute 17 is formed at the bottom of the cantilever 10. Guide rails 18 are fixedly installed on both sides inside the chute 17. A slider 21 is movably installed inside the chute 17. One side of the cantilever 10 is fixedly installed between the two side blocks 14 on the same side of the upper mounting block 8 and the lower mounting block 9. Based on this, through the setting of the cantilever 10, installation adjustment can be provided for a plurality of suspension seats 11 and guide seats 12. The setting of the chute 17 can provide installation and displacement conditions for the slider 21. A threaded hole 22 is formed inside the slider 21, and the slider 21 is slidably installed inside the chute 17. Based on this, through the setting of the slidable and adjustable slider 21, the installation positions of the suspension seat 11 and the guide seat 12 can be quickly adjusted.

[0034] Embodiment 2:

[0035] Referring to Figures 4 - 5 , this is the second embodiment of the present utility model. The difference between this embodiment and the first embodiment is that: a suspension rod 19 is fixedly installed at the top of the suspension seat 11, a rotating groove 20 is formed at the bottom of the suspension seat 11, the suspension rod 19 is threadedly connected in the threaded hole 22, a ball seat 23 is fixedly installed at the top of the guide seat 12, a through hole 24 is formed inside the guide seat 12, and the ball seat 23 is rotatably installed inside the rotating groove 20. Based on this, by means of the setting of the suspension seat 11 and the guide seat 12 with a rotatable angle, the steel wire conveyed by the steel wire coiling and feeding frame 2 to the feeding seat 4 can be guided, preventing the angle of the steel wire during conveying from being too large and causing bending friction with the feeding seat 4.

[0036] It should be noted that the present utility model is a cold heading machine for fastener forming. When the steel wire is conveyed from the steel wire coil feeding rack 2 towards the feeding seat 4, one end of the steel wire can sequentially pass through the perforations 24 in the three guiding seats 12, and finally one end of the steel wire enters into the feeding seat 4. When the height or the tension of the steel wire output by the steel wire coil feeding rack 2 changes, the force of the steel wire drives the guiding seat 12 to rotate in the rotating groove 20 at the bottom of the suspension seat 11 with the ball seat 23 at the top as the axis, so as to adjust the angle of the corresponding rotating groove 20. Furthermore, by means of the adaptive change adjustment of the angles of the multiple guiding seats 12, the angle of the steel wire input into the feeding seat 4 is gradually corrected, thereby preventing the input angle of the steel wire from being too large, reducing the wear rate of the steel wire and the feeding seat 4, and at the same time, improving the smoothness of the steel wire input.

[0037] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
