Description

Technical Field

[0001] This utility model relates to the field of wire drawing machine technology, and in particular, to a special wire dropper for an inverted wire drawing machine. Background Technology

[0002] The inverted wire drawing machine is designed for continuous, non-twisting operation with heavy coils. It has both drawing and take-up functions and is suitable for drawing high, medium, and low carbon steel wire, special-shaped steel wire, stainless steel wire, and thick non-ferrous metal wire. It is especially suitable for the standard parts industry and shelving manufacturing industry. The inverted wire drawing machine belongs to the rebar wire drawing machine and is used for drawing metal wire. The equipment adopts a vertical downward working method of the drum outlet, and the finished product falls directly into the wire dropper.

[0003] Currently, Chinese patent CN221388203U discloses an inverted wire drawing and unloading frame, including a chassis. Several columns are circumferentially arranged on the top surface of the chassis, and a conical frame is coaxially mounted on the top of each column. When drawing soft, thin iron wire, the conical frame increases the guiding height, making it easier for the wire to be drawn into the unloading frame under its guidance. However, when producing other types of iron wire, the conical frame needs to be removed, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a special wire dropper for an inverted wire drawing machine.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] A wire dropper for an inverted wire drawing machine includes a chassis. Several columns are arranged circumferentially on the top surface of the chassis. The columns cooperate to form a storage space. A conical frame is arranged in the storage space. The conical frame is adapted to be able to be put into the storage space or pushed out of the storage space.

[0007] Preferably, a sliding groove is provided on the side wall of the column, and a corresponding locking block is provided on the outer periphery of the conical frame, the locking block being engaged in the sliding groove.

[0008] Preferably, the bottom of the storage space is provided with a push-out mechanism, and the push-out end of the push-out mechanism is connected to the conical frame.

[0009] Preferably, a spring is connected between the tapered frame and the column, the spring being used to push the tapered frame out of the storage space, and the column is also provided with a limiting mechanism for keeping the tapered frame inside the storage space.

[0010] Preferably, the ejection mechanism includes a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder.

[0011] Preferably, the limiting mechanism includes a limiting plate, the two ends of which are detachably fixed to two columns, and the top of the conical frame abuts against the bottom surface of the limiting plate.

[0012] Preferably, a threaded post is provided in the storage space, and the tapered frame is threadedly connected to the threaded post.

[0013] Preferably, the spring is a damping spring.

[0014] The beneficial effects of this utility model are: by setting up a storage space, the tapered frame can be retracted or ejected. When ejected, the guide height of the wire dropper is increased, which can be used to guide and receive soft and thin iron wires; when retracted, the tapered frame is located within the storage space, which makes it less likely to cause other types of iron wires to be retracted normally.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figures 1 to 4As shown, a wire guide frame for an inverted wire drawing machine includes a base 1. Several columns 2 are arranged circumferentially on the top surface of the base 1, thus forming a storage space 3 between the columns 2. Unlike existing technologies, the conical frame 4 is adapted and installed within the conical frame 4. As disclosed in Chinese Patent No. CN221388203U, the conical frame 4 is not housed between the columns 2; instead, it is supported on a disc and cannot be housed. In this invention, the conical frame 4 is directly fitted into the storage space 3, allowing it to be pushed out of the storage space 3 to guide the wire, or it can be repositioned into the storage space 3 to prevent interference with the wire.

[0022] like Figure 3 As shown, in some embodiments, the bottom of the storage space 3 may be provided with an ejection mechanism 7, such as a cylinder, hydraulic cylinder, or electric cylinder, and the ejection end of the ejection mechanism 7 is connected to the conical frame 4. In this way, the ejection mechanism 7 can be used to automatically eject and retract the conical frame 4.

[0023] For example, a sliding groove 5 can be provided on the side wall of the column 2, and a corresponding locking block 6 is provided on the outer periphery of the conical frame 4. By locking the locking block 6 into the sliding groove 5, the vertical movement of the conical frame 4 can be guided, thereby making the ejection and retraction of the conical frame 4 more stable.

[0024] like Figure 2 As shown, in other embodiments, a spring 8 can be connected between the conical frame 4 and the column 2. For example, the spring 8 can be specifically connected between the locking block 6 and the groove wall of the sliding groove 5. The elastic force of the spring 8 on the locking block 6 will push the conical frame 4 out of the storage space 3. In addition, a limiting mechanism 9 is provided on the column 2, which can keep the conical frame 4 within the storage space 3. Therefore, this utility model can have the following usage process:

[0025] When drawing soft and thin iron wire, the limiting mechanism 9 is released from the restriction on the conical frame 4. Then, the conical frame 4 is pushed out under the action of the spring 8, thereby increasing the guiding height of the wire dropper.

[0026] When processing other types of wire, the tapered frame 4 can be pressed back into the storage space 3, and the limiting mechanism 9 can be operated to restrict the tapered frame 4 back into the storage space 3. At this time, the guiding height of the wire dropper is reduced, and it is less likely to cause interference to the wire.

[0027] In a preferred embodiment, the limiting mechanism 9 may include a limiting plate 10, with both ends of the limiting plate 10 detachably fixed to two opposing columns 2. For example, threaded holes may be provided on the top surface of the corresponding columns 2, and the ends of the limiting plate 10 are fixed to the columns 2 by fasteners such as bolts. After the tapered frame 4 is inserted into the storage space 3, the limiting plate 10 can be fastened to the columns 2. At this time, the top of the tapered frame 4 will abut against the bottom surface of the limiting plate 10, thereby confining the tapered frame 4 within the storage space 3.

[0028] like Figure 1 As shown, in some other embodiments, a threaded post 11 may be provided in the storage space 3, and the conical frame 4 is threadedly connected to the threaded post 11, thereby enabling the storage space 3 to be retracted and ejected by screwing the conical frame 4.

[0029] In the above three embodiments, the method of ejecting the conical frame 4 by means of ejection mechanism 7 has the disadvantages of high cost and complex electrical control, while the method of twisting the conical frame 4 is relatively inconvenient to operate. The method of using spring 8 and limit mechanism 9 can automatically eject the conical frame 4 by means of spring 8, which is not only more convenient to operate, but also allows the conical frame 4 to bounce to a certain extent after the wire comes into contact with the conical frame 4 during the actual wire pulling operation, thereby reducing the impact between the wire and the conical frame 4.

[0030] In cases where possible, spring 8 can be preferably a damping spring 8, for example, a spring 8 equipped with a damper (not shown), or a spring 8 that has damping properties of its own. This allows the cone frame 4 to be ejected slowly, reducing the risk of accidental injury to personnel.

[0031] The above description is merely a preferred embodiment of this utility model. It should be understood that this utility model is not limited to the forms disclosed herein and should not be construed as excluding other embodiments. It can be used in various other combinations, modifications, and environments, and can be altered within the scope of the concept described herein through the above teachings or related technologies or knowledge. Modifications and variations made by those skilled in the art that do not depart from the spirit and scope of this utility model should be protected within the scope of the appended claims.
