Description

Technical Field

[0001] The utility model relates to the technical field of a spinning machine, in particular to a spinning tube for a spinning machine of a high-speed hot-rolled wire production line. Background Art

[0002] In the production process of high-speed hot-rolled wire, the laying machine is one of the key equipment. The laying machine is used to form high-temperature molten metal materials into wires of a certain shape and size. In this process, the metal material needs to pass through the laying pipe to form a wire of a certain shape, and then the wire is input into the laying disk, and finally the laying disk outputs the wire. In particular, the bending section of the laying pipe needs to withstand high temperature and friction.

[0003] After searching the patent with patent announcement number CN201910606830.1, a patent named a self-repairing spinning pipe is disclosed, which adopts the method of inner tube lining the outer tube, and the inner tube is only constrained to move relative to the outer tube by friction contact with the outer tube. When the spinning tube rotates around its axis, the inner tube can move progressively in the outer tube in response to the heating and cooling cycle. The progressive movement is used to periodically change the inner tube surface in friction contact with the hot-rolled product and thus update the inner tube surface in friction contact with the hot-rolled product, avoiding persistent friction contact with any area of ​​the inner wall of the inner tube. Although the patent technology can reduce the wear of the spinning tube to a certain extent, under long-term use, the impact of the wire on the bending section of the spinning tube and the vibration of the spinning tube itself will aggravate the wear of the spinning tube, making the spinning tube unusable. In addition, when replacing the spinning tube in the patent, multiple parts need to be removed and replaced with a new spinning tube. The operation process is very cumbersome and even affects the operation of the entire machine after reinstallation. Utility Model Content

[0004] In view of this, the utility model aims to provide a spinning tube for a spinning machine of a high-speed hot-rolled wire production line, which can facilitate the replacement of the spinning tube, reduce the vibration of the spinning tube itself, and extend the service life of the spinning tube.

[0005] In order to achieve the above object, the technical solution of the utility model is implemented as follows:

[0006] A laying pipe for a laying machine of a high-speed hot-rolled wire production line, comprising an arc-shaped pipe, connecting pipes connected to both ends of the arc-shaped pipe, and a connecting piece provided between the arc-shaped pipe and the connecting pipe;

[0007] The connecting piece includes at least two reinforcing ribs, a connecting bolt pair connecting two adjacent reinforcing ribs, one end of the reinforcing rib overlaps the arc tube, and the other end overlaps the connecting tube, and the reinforcing rib is arranged along the circumference of the connecting tube.

[0008] Furthermore, both ends of the arc-shaped tube are provided with threads, and the connecting tube is threadedly connected to the corresponding end of the arc-shaped tube.

[0009] Furthermore, a connecting sub-tube is threadedly sleeved on the end of the connecting tube away from the arc-shaped tube, and the connecting sub-tube is used for the wire to pass through.

[0010] Furthermore, the number of the connecting bolt pairs between two adjacent reinforcing ribs is at least two, and the directions of the threaded ends of the two adjacent connecting bolt pairs are opposite.

[0011] Furthermore, a plug-in block is provided on one side of the reinforcing rib in contact with the arc tube and on one side of the reinforcing rib in contact with the connecting tube, and a plug-in groove for plugging and cooperating with the corresponding plug-in block is provided at the end of the arc tube and the end of the connecting tube.

[0012] Furthermore, the number of the plug-in grooves on the arc-shaped tube and the number of the plug-in grooves on the connecting tube are the same as the number of the reinforcing ribs.

[0013] Furthermore, it also includes a machine body, on which are provided reinforcing rods having the same number as the connecting members, and the reinforcing rods are fixedly connected to the reinforcing ribs of one of the corresponding connecting members.

[0014] Furthermore, the reinforcing rods are fixedly connected by a plurality of reinforcing transverse ribs, and the reinforcing transverse ribs are fixedly connected by a plurality of reinforcing longitudinal ribs.

[0015] Compared with the prior art, the utility model has the following advantages:

[0016] The utility model discloses a spinning tube for a spinning machine of a high-speed hot-rolled wire production line, which divides the spinning tube into an arc tube and two sections of connecting tubes by means of an arc tube and a connecting tube. After the arc tube is subjected to multiple impacts and wears, the arc tube and the connecting tube can be separated by removing the connecting piece, so as to facilitate replacement of the arc tube. After replacing the arc tube, the arc tube and the connecting tube can be stably fastened together by the reinforcing ribs and the connecting bolt pair of the connecting piece, thereby reducing the self-vibration of the arc tube and the connecting tube and extending the service life of the arc tube and the connecting tube.

[0017] Secondly, threads are provided at both ends of the arc tube, and the threaded tube is threadably connected to the arc tube, which can enhance the connection strength between the connecting tube and the arc tube. Furthermore, the threaded ends of the two adjacent bolts between the two adjacent reinforcing ribs of the connector are in opposite directions. When the arc tube and the connecting tube vibrate, the connecting bolt pair can only vibrate in one direction, and of the two connecting bolt pairs in opposite directions, only one connecting bolt pair has a tendency to loosen during vibration, while the other connecting bolt pair has a tendency to tighten. Therefore, the two adjacent reinforcing ribs are not easy to loosen, thereby improving the connection strength between the connecting tube and the arc tube.

[0018] Furthermore, a plug-in block is provided on the reinforcing rib, and a plug-in groove which is plugged into and matched with the plug-in block is opened on the arc tube and the connecting tube, so that when the arc tube and the connecting tube are connected through the reinforcing rib, the plug-in block on the reinforcing rib is inserted into the plug-in groove. When the reinforcing rib vibrates, the separation of the connecting tube and the arc tube can be better limited, thereby further improving the connection effect of the reinforcing rib on the arc tube and the connecting tube.

[0019] Finally, reinforcing rods are used to fix the reinforcing ribs to the machine body, which can disperse the vibration of the reinforcing ribs to the machine body through the reinforcing rods, thereby reducing the vibration amplitude of the reinforcing ribs. The reinforcing rods are then fixed together by multiple reinforcing transverse ribs and reinforcing longitudinal ribs, which can maximize the stabilizing effect of the reinforcing rods.

[0031] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0032] This embodiment relates to a spinning tube for a spinning machine of a high-speed hot-rolled wire production line, an exemplary structure of which is as follows: Figure 1-5 shown.

[0033] Overall, if Figure 1-2 As shown, the spinning tube used for the spinning machine of the high-speed hot-rolled wire production line includes an arc-shaped tube 1, connecting tubes 2 connected to both ends of the arc-shaped tube 1, and a connecting member arranged between the arc-shaped tube 1 and the connecting tube 2, the connecting member includes at least two reinforcing ribs 3, a connecting bolt pair 4 connecting two adjacent reinforcing ribs 3, one end of the reinforcing rib 3 overlaps the arc-shaped tube 1, and the other end overlaps the connecting tube 2, and the reinforcing rib 3 is arranged along the circumference of the connecting tube 2.

[0034] Among them, the arc tube 1 and the connecting tube 2 are both fixedly connected with a mounting plate, and a through hole is provided on the mounting plate, through which the connecting bolt pair 4 passes, and the connecting bolt pair 4 is used to fix and connect two adjacent reinforcing ribs 3 through the mounting plate. The number of reinforcing ribs 3 is preferably multiple, and the multiple reinforcing ribs 3 are arranged along the circumference of the connecting tube 2. After the multiple reinforcing ribs 3 are wrapped between the connecting tube 2 and the arc tube 1, the adjacent reinforcing ribs 3 are fixedly connected by the connecting bolt pair 4, so that the connecting tube 2 and the arc tube 1 are stably connected together.

[0035] In addition, if Figure 3As shown, threads are provided at both ends of the arc tube 1, the connecting tube 2 is threadedly connected to the corresponding end of the arc tube 1, and a connecting sub-tube 5 is threadedly sleeved at the end of the connecting tube 2 away from the arc tube 1. In this way, the connection strength between the connecting tube 2 and the arc tube 1 can be improved, ensuring that the wire can pass through the connecting tube 2 and the arc tube 1 smoothly in sequence, and the connecting sub-tube 5 is threadedly sleeved on the connecting tube 2, and the connecting sub-tube 5 is used to input and output the wire, and it can be ensured that without affecting other components, only the connecting tube 2 is rotated, and the connecting tube 2 can move toward the connecting sub-tube 5, so that the connecting tube 2 and the arc tube 1 are disconnected from the threaded connection, so that the arc tube 1 can be removed and replaced.

[0036] In this embodiment, there are at least two connecting bolt pairs 4 between two adjacent reinforcing ribs 3, and the directions of the threaded ends of the two adjacent connecting bolt pairs 4 are opposite. When the arc tube 1 vibrates and the reinforcing ribs 3 vibrate, the connecting bolt pairs 4 can only vibrate in one direction, and only one of the two connecting bolt pairs 4 in opposite directions has a tendency to loosen during vibration, while the other connecting bolt pair 4 has a tendency to tighten, so the adjacent reinforcing ribs 3 are not easy to loosen, thereby improving the connection strength between the connecting tube 2 and the arc tube 1.

[0037] In this embodiment, if Figure 4 As shown, the side where the reinforcing rib 3 contacts the arc tube 1 and the side where the reinforcing rib 3 contacts the connecting tube 2 are both fixedly connected with a plug-in block 6, and the ends of the arc tube 1 and the connecting tube 2 are both provided with a plug-in slot 7 that is plugged and matched with the corresponding plug-in block 6. The cross-section of the plug-in block 6 is preferably arc-shaped, and the arc surface of the plug-in block 6 faces the plug-in slot 7. When the reinforcing rib 3 is buckled on the connecting tube 2 and the arc tube 1, the plug-in block 6 on the reinforcing rib 3 is inserted into the corresponding plug-in slot 7, which can limit the vibration between the arc tube 1 and the connecting tube 2, so that the connecting tube 2 and the arc tube 1 are not easily separated.

[0038] Preferably, the number of the inserting grooves 7 on the arc tube 1 and the number of the inserting grooves 7 on the connecting tube 2 are the same as the number of the reinforcing ribs 3 .

[0039] In this embodiment, if Figure 5 As shown, the machine body 8 is also included, and the machine body 8 is provided with reinforcing rods 9 of the same number as the connecting parts, and the reinforcing rods 9 are fixedly connected to one of the reinforcing ribs 3 in the corresponding connecting parts. Among them, the machine body 8 is the whole of the spinning machine, and the spinning tube is a component of the spinning machine. The whole spinning machine has a heavy weight, so the reinforcing ribs 3 and the machine body 8 are connected by the reinforcing rods 9, and the vibration of the reinforcing ribs 3 can be dispersed to the machine body 8, so that after the arc tube 1 is impacted by the wire and vibrates, the vibration of the arc tube 1 itself can be reduced.

[0040] In addition, the reinforcing rods 9 are fixedly connected by a plurality of reinforcing transverse ribs 10 , and the reinforcing transverse ribs 10 are fixedly connected by a plurality of reinforcing longitudinal ribs 11 , so that the connection strength of the reinforcing rods 9 can be improved.

[0041] The working process of the laying pipe used in the laying machine of the high-speed hot-rolled wire production line of this embodiment is as follows:

[0042] First, when disassembling the arc tube 1, twist the connecting bolt pair 4 to loosen all the reinforcing ribs 3, and disengage the plug-in block 6 on the reinforcing rib 3 from the plug-in groove 7, thereby releasing the fixation of the reinforcing rib 3 to the connecting tube 2 and the arc tube 1, and then twist the connecting tube 2. Since the thread direction between the connecting tube 2 and the connecting sub-tube 5 is opposite to the thread direction between the connecting tube 2 and the arc tube 1, when the connecting tube 2 is rotated, the connecting tube 2 can be moved toward the connecting sub-tube 5, and finally the connecting tube 2 can be disengaged from the threaded connection with the arc tube 1, so that the arc tube 1 can be removed.

[0043] When replacing the arc tube 1, place the arc tube 1 between the two connecting tubes 2, and screw the connecting tubes 2 to move the two connecting tubes 2 toward the arc tube 1 and tighten them with the arc tube 1 threads, then buckle the reinforcing rib 3 between the connecting tube 2 and the arc tube 1, align the plug-in block 6 on the reinforcing rib 3 with the plug-in groove 7, and insert it into the plug-in groove 7, finally use the connecting bolt pair 4 to fix the reinforcing rib 3 together.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
