[0002] Cold heading machine is an important equipment in mechanical manufacturing, mainly used for cold forming of metal materials. Cold heading machine is a stamping machine in mechanical manufacturing. It uses the plasticity of metal to process metal materials at room temperature to form them into the required shape (such as bolts, nuts and other fasteners). When feeding the cold heading machine, the wire ring is generally placed on the feeding rack and fed by a traction machine. However, there are still some problems when using the traditional feeding rack.
[0003] The outer diameter of traditional feed racks is fixed, which causes wire rings of different inner diameters to be placed on the outside of the feed rack. When the inner diameter of the wire ring is larger than the outer diameter of the feed rack, the wire ring is not stable enough during rotation and loading, which may easily lead to safety hazards. Therefore, a feed rack structure for cold heading machines is needed to solve the above problems. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] The embodiment of the utility model provides a feeding rack structure for a cold heading machine, such as Figure 1-Figure 5 As shown, a feed rack structure for a cold heading machine includes a bracket 1 and a protective sleeve 2; the protective sleeve 2 is fixed to the outside of the top of the bracket 1, a screw 7 is provided at the top of the bracket 1, a screw sleeve 4 is installed on the outside of the screw 7, an adjustment structure 3 is provided on the outside of the screw sleeve 4, a motor 5 is installed at the bottom end of the bracket 1, and a fixed leg 6 is fixed to the bottom end of the bracket 1; an auxiliary structure 8 is provided at the notch of the protective sleeve 2.
[0023] In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the adjustment structure 3 includes an adjustment plate 301, a connecting plate 302, a connecting seat 303, a fixed seat 304, a ball 305, a guide groove 306 and a guide block 307. The fixed seat 304 is installed on the outside of the screw sleeve 4. The fixing seat 304 is hinged with the connecting plate 302 inside, and the bottom end of the connecting plate 302 is hinged with the connecting seat 303. One end of the connecting seat 303 is fixed with the adjustment plate 301. The inside of one side surface of the adjustment plate 301 is provided with a ball 305. The guide groove 306 is opened inside the top of the bracket 1. The guide block 307 is installed inside the guide groove 306. The top of the guide block 307 is fixed to the bottom end of the adjustment plate 301. There are several adjustment plates 301, and the several adjustment plates 301 are distributed in a ring shape on the outside of the screw sleeve 4. There are several balls 305, and the several balls 305 are arranged at equal intervals on one side of the adjustment plate 301.
[0024] Specifically, in this embodiment: when the cold heading machine is loaded, the wire ring is sleeved on the top of the bracket 1 outside the screw sleeve 4. After the sleeve is sleeved, the external power supply starts the motor 5. After starting, the motor 5 will drive the screw 7 to rotate. When the screw 7 rotates, since it is threadedly connected to the screw sleeve 4, it will move downward on the outside of the screw 7 when the screw sleeve 4 is limited. When the screw sleeve 4 moves downward, the fixing seat 304, the connecting plate 302 and the connecting seat 303 are hinged, so the adjusting plate 301 can be pushed to one side. Since the guide block 307 moves inside the guide groove 306, the adjusting plate 301 is guided, so that the adjusting plate 301 is more stable when moving. When the outer side of the adjusting plate 301 is fitted against the inner ring of the wire ring, it stops moving, thereby limiting the wire ring, making the wire ring more stable when rotating. Since the position of the adjusting plate 301 can be adjusted, it can limit wire rings with different inner diameters. In a further preferred embodiment of the present invention, Figure 1-Figure 5 As shown: the auxiliary structure 8 includes a movable sleeve 801, a fixed column 802 and a movable groove 803. The fixed column 802 is fixed to the notch of the protective sleeve 2 at the top of the bracket 1. The outer side of the fixed column 802 is provided with a movable sleeve 801. The interior of the movable sleeve 801 is provided with a movable groove 803. The movable sleeve 801 is sleeved on the outer side of the fixed column 802. A movable connection is formed between the movable sleeve 801 and the fixed column 802. An internal thread is provided on the inner side of the screw sleeve 4, and an external thread is provided on the outer side of the screw rod 7. A threaded connection is formed between the screw sleeve 4 and the screw rod 7.
[0025] Specifically, in this embodiment, when the wire ring is loaded by the traction machine, the ball 305 can be used to rotate inside the adjustment plate 301 without affecting the rotation of the wire ring. When the steel wire in the wire ring is moving, the steel wire will drive the movable sleeve 801 to rotate on the outside of the fixed column 802. At this time, the movable sleeve 801 is used to guide the steel wire so that the steel wire will not contact the notch of the protective sleeve 2 when moving and cause damage to the outside of the steel wire, thereby completing the guided loading work.
[0026] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
