DETAILED DESCRIPTION

[0017] The technical scheme of the utility model will be described clearly and completely in combination with embodiments. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0018] For example, Figure 1 , Figure 2 ​As shown, an automatic wire drawing machine comprises a machine body 1, and a wire drawing station and a feeding station are arranged on both sides of the machine body 1. The wire drawing station can comprise a wire drawing plate 2 capable of moving reciprocatingly along the vertical direction, for example, the wire drawing plate 2 can be moved reciprocatingly through a crank slider mechanism, and of course, other driving modes of the wire drawing plate 2 in the prior art can also be referred to. The feeding station comprises a feeding bin 3 arranged on the machine body 1, and the feeding bin 3 can have an inclined bottom plate and a side plate, and an opening 4 at the bottom end is defined between the bottom plate and the side plate.

[0019] A support plate 8 is arranged below the feeding bin 3 on the machine body 1, and a baffle 7 and a push plate 9 are arranged in sequence from top to bottom between the opening 4 and the support plate 8, and the baffle 7 and the push plate 9 are both adapted to move along the horizontal direction, for example, both of them can be moved through the ejection of a cylinder, an electric cylinder or an oil cylinder, etc. An ejection mechanism. A blocking plate 5 is further arranged between the baffle 7 and the push plate 9, and the blocking plate 5 is provided with a material passing port 6, and more importantly, the material passing port 6 and the opening 4 are arranged in a staggered manner in the horizontal direction. The baffle 7 is further provided with a receiving port 10.

[0020] The shaft workpiece that needs to be drawn wire is contained in the feeding bin 3, and under the action of gravity, the workpiece has a downward movement tendency through the opening 4. Under the stop of the baffle 7 in the blocking position, the workpiece is kept at the opening 4 and cannot fall out.

[0021] In the receiving position of the baffle 7, the receiving port 10 on the blocking plate is opposite to the opening 4, and the workpiece will fall into the receiving port 10 and be stopped by the bottom blocking plate 5. At this time, since the size of the receiving port 10 is controllable, the number of workpieces accepted by the receiving port 10 is also controllable, for example, it can be designed that only a single workpiece is contained in the receiving port 10.

[0022] In the discharging position of the baffle 7, the baffle 7 will move to make the receiving port 10 opposite to the material passing port 6, at this time, the workpiece will be discharged downward, and then the push plate 9 will send the workpiece into the wire drawing plate 2 to complete the wire drawing. At the same time, the baffle 7 will also be in the above-mentioned blocking position, so that the workpiece in the feeding bin 3 will not be unexpectedly dropped out.

[0023] In a specific example, the blocking plate 5 is adapted to change the installation height, which makes the spacing between the blocking plate 5 and the feeding bin 3 adjustable. For example, after the above-mentioned spacing is expected to be changed, the baffle 7 can be replaced, especially the baffle 7 with an expected thickness can be replaced to receive workpieces of different diameters.

[0024] For example, the machine body 1 is provided with a mounting groove 14 extending in the vertical direction, and the blocking plate 5 is fixed in the mounting groove 14 by fasteners (not shown in the figure). In another possible implementation, mounting holes of different heights can also be reserved on the machine body 1 in the vertical direction (not shown in the figure), and then the blocking plate 5 is mounted in the mounting holes of different heights by fasteners. However, it can be understood that the mounting groove 14 can provide a more free and precise installation height adjustment mode for the blocking plate 5.

[0025] In some other embodiments, the bottom of the feeding bin 3 is configured to have a closed surface 11, and the closed surface 11 is located between the opening 4 and the material passing port 6 in the transverse direction, that is, the receiving port 10 passes through the closed surface 11 when it is moved between the opening 4 and the material passing port 6, and a relatively closed space is formed in the receiving port 10 at this time. Further, the closed surface 11 is also adapted to be provided with a material suction port 12, and the material suction port 12 is connected with a negative pressure mechanism 13. The negative pressure mechanism 13 can be a gas pump or other mechanism for realizing dust suction by using negative pressure in the prior art.

[0026] During the movement of the blocking plate 7 from the receiving position to the discharging position, the workpiece in the receiving port 10 is opposite to the material suction port 12, so that the impurities adhered to the workpiece can be sucked out from the material suction port 12, and the impurities are not easy to enter the thread rolling plate 2 to affect the thread rolling quality or damage the thread rolling plate 2.

[0027] In a preferred example, the blocking plate 5 is also provided with a slope surface 15, and the slope surface 15 is located between the opening 4 and the material passing port 6 in the transverse direction and is configured to be inclined to the side of the material passing port 6. It can be understood that, during the movement of the plate from the receiving position to the discharging position, the workpiece will roll along the slope surface 15 under the action of gravity due to the provision of the slope surface 15, which enables the outer circumferential surface of the workpiece to be exposed to the material suction port 12, thereby improving the impurity suction effect.

[0028] The above description is only a preferred embodiment of the present application, and it should be understood that the present application is not limited to the form disclosed herein, and should not be considered as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein by using the above teaching or related technology or knowledge. Any modification and change made by those skilled in the art without departing from the spirit and scope of the present application shall be within the protection scope of the claims of the present application.
