Description

Technical Field

[0001] This invention belongs to the field of rebar precision rolling technology, and particularly relates to a rebar precision rolling processing machine and precision rolling process. Background Technology

[0002] Precision rolling technology includes processes such as die making, bar heating, precision rolling, and finishing and straightening. Compared with existing wedge cross rolling roughing technology, it increases material saving rate by more than 10% and improves the overall mechanical properties of parts by more than 5%.

[0003] A rebar finishing milling machine and finishing milling process are disclosed in CN114082781A. The cleaning unit includes a straightening pusher, a rotating shaft, and a steel brush holder. The straightening pusher is mounted on an annular sleeve via a sliding fit. A rotating shaft is mounted on the inner wall of the straightening pusher via bearings and is connected to a rotating plate via a movable mechanism. The steel brush holder is mounted on the inner ring of the annular sleeve, and steel bristles are evenly arranged on its inner wall. The straightening pusher is connected to the steel bristles on the steel brush holder via a sliding mechanism. A servo motor drives a drive gear to rotate, which in turn meshes with a rotating gear to make the annular sleeve rotate synchronously. The steel bristles on the steel brush holder then rotate and rub away the iron oxide scale adhering to the surface of the rebar.

[0004] In the above scheme, because the thread groove of the rebar is concave inward, the surface flatness of the rebar is poor. The steel bristles of the cleaning unit are not easy to effectively clean the surface of the rebar at different positions. In addition, in the above scheme, the steel bristles are kept vertical by correcting the push frame, which makes the head of the steel bristles easy to wear, causing the bristles to become shorter during wear, thus reducing the cleaning effect of the steel bristles on the surface of the rebar. Summary of the Invention

[0005] The purpose of this invention is to provide a rebar finishing milling machine and finishing milling process, which aims to solve the technical problem that the steel brushes of the cleaning unit in the prior art are not easy to effectively clean the surface of the rebar at different locations during cleaning.

[0006] The present invention is implemented as follows: a rebar precision rolling processing machine includes a base, a refining mechanism is provided on the base, and a mounting seat is provided on one side of the refining mechanism;

[0007] The mounting base is rotatably connected to a sleeve, which can rotate continuously under the drive of a motor. The sleeve has multiple mechanism slots arranged circumferentially along its inner wall. A sliding seat is slidably connected to the inner wall of the mechanism slot. An elastic element is connected between one end face of the sliding seat and the mechanism slot. A driving assembly is provided between the other end face of the sliding seat and the sleeve. The driving assembly is used to push the sliding seat to move.

[0008] The sliding seat is slidably sealed to a sliding plate, and a second elastic element is provided between the sliding plate and the sliding seat. Several brush rods are fixedly connected to the sliding plate, and a support assembly is fixedly connected to the sliding plate. The support assembly can provide auxiliary support for all brush rods at the same time, and multiple brush strips are fixedly connected to the support assembly.

[0009] The mechanism groove is provided with a flow guiding mechanism, and the sleeve can be fixedly connected to a water tank. The flow guiding mechanism can continuously guide and cool the connection between the brush rod and the threaded steel.

[0010] A temperature sensor is installed on the slide plate, which can monitor the temperature of all brush rods. The temperature sensor is electrically connected to the support assembly. A pressure sensor is installed at the connection position between the sliding seat and the drive assembly, and the pressure sensor is electrically connected to the drive assembly.

[0011] Further technical solution: The support assembly includes an electric telescopic sleeve and an auxiliary support plate. The fixed end of the electric telescopic sleeve is fixedly connected to the slide plate, and the telescopic end of the electric telescopic sleeve is fixedly connected to the auxiliary support plate. All brush rods slide and are connected through the auxiliary support plate. The temperature sensor is electrically connected to the electric telescopic sleeve, and all brush bars are fixedly connected to the auxiliary support plate.

[0012] Further technical solution: The drive assembly includes an electric telescopic rod, a push plate, and a spring;

[0013] One end of the electric telescopic rod is fixedly connected to the sleeve, and the other end of the electric telescopic rod is fixedly connected to the push plate. Several springs are provided between the push plate and the sliding seat, and the pressure sensor is located at the connection position between the sliding seat and the springs.

[0014] Further technical solution: The flow guiding mechanism includes a first flow guiding component and a second flow guiding component. The sleeve is provided with a sleeve that can communicate with the water tank. The first flow guiding component and the second flow guiding component are both connected between the sleeve and the sliding seat. All brush rods are connected to the sliding seat.

[0015] The driving component can control the first flow guiding component to be turned on, and the supporting component can control the filtration rate of the second flow guiding component.

[0016] Further technical solution: The first flow guiding component includes a flow guiding channel, a guide hole, and a telescopic tube;

[0017] The side wall of the mechanism groove is provided with a flow channel communicating with the sleeve. The guide hole is provided on the push plate. A telescopic tube is connected between the guide hole and the sliding seat. When the push plate moves vertically to a certain position, the flow channel and the guide hole are connected.

[0018] Further technical solution: The second flow guiding component includes a vertical plate, a baffle, a guide tube, and a rubber tube;

[0019] The sliding seat is fixedly connected to a conduit, which is connected to a sleeve via a rubber tube. One end of the vertical plate is fixedly connected to an auxiliary support plate, and the other end of the vertical plate is fixedly connected to a baffle. The baffle is disposed in the sliding seat and abuts against the end of the conduit.

[0020] A further technical solution: The end of the brush rod away from the slide plate is provided with several steel wire bristles.

[0021] A rebar finishing rolling process, applied to any of the rebar finishing rolling machines described above, includes the following steps:

[0022] S1: Steel is heated in a furnace, and after heating, it is processed by a rolling mill in sequence through rough rolling, intermediate rolling and finish rolling to form rebar.

[0023] S2: The conveying mechanism conveys the rebar, and the finishing mechanism rolls the rebar;

[0024] S3: The threaded steel bar passes through the sleeve, and the drive assembly moves the sliding seat to the outside of the mechanism groove. At this time, the brush rod moves synchronously, and the slide plate drives the brush rod to abut against the thread groove of the threaded steel bar. At this time, the brush bar abuts against the outer surface of the threaded steel bar. As the sleeve rotates under the electric drive, the brush bar and the brush rod work together to thoroughly remove the iron oxide scale from the outer surface of the threaded steel bar and the inner surface of the thread groove.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0026] 1. The drive assembly moves the sliding seat to the outside of the mechanism slot. At this time, the brush rod moves synchronously. The slide plate drives the brush rod to abut against the thread groove of the threaded steel, and the brush strip abuts against the outer surface of the threaded steel. As the sleeve rotates under the electric drive, the brush strip and the brush rod work together to thoroughly remove the iron oxide scale from the outer surface of the threaded steel and the inner surface of the thread groove.

[0027] 2. When the brush rod temperature is too high, the temperature sensor controls the electric telescopic sleeve to start. The electric telescopic sleeve drives the auxiliary support plate to move towards the root of the brush rod. The auxiliary support plate reduces the limiting force on the brush rod, avoiding excessive friction and heat between the brush rod and the surface of the threaded steel, which could cause the brush rod to be squeezed or deformed by heat. At this time, the auxiliary support plate drives the vertical plate to push the baffle. The baffle moves up, the outlet of the guide tube increases, and the cooling effect of the water flow on the brush rod and the surface of the threaded steel increases, further preventing the brush rod from being deformed by heat.

[0028] 3. When the brush rod wears too much, the pressure sensor controls the electric telescopic rod to extend. The electric telescopic rod pushes the push plate, and the push plate pushes the sliding seat through the spring. The sliding seat drives the brush rod and brush strip closer to the threaded steel to ensure the cleaning effect of iron oxide scale on the surface of the threaded steel.

[0029] 4. When the push plate moves vertically to a certain position, the flow channel and the guide hole are connected, so that the water flows through the sleeve, the flow channel, the guide hole and the telescopic pipe in sequence. Then the water flows into the sliding seat. The water flows through the brush rod to cool the surface of the threaded steel, so as to avoid the brush rod and brush strip from being too tightly pressed against the threaded steel and generating a lot of frictional heat.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0041] like Figures 1-8 As shown, this invention provides a rebar precision rolling processing machine, including a base 1, on which a refining mechanism 2 is provided. The refining mechanism 2 is the prior art in the background art. The drive motor in the refining mechanism 2 drives the roller to roll the rebar. A mounting seat 3 is provided on one side of the refining mechanism 2.

[0042] The mounting base 3 is rotatably connected to a sleeve 4, which can rotate continuously under the drive of a motor. The sleeve 4 has a plurality of mechanism grooves 5 arranged in a ring along its inner wall. A sliding seat 6 is slidably connected to the inner wall of the mechanism groove 5. An elastic element 10 is connected between one end face of the sliding seat 6 and the mechanism groove 5. A driving assembly 7 is arranged between the other end face of the sliding seat 6 and the sleeve 4. The driving assembly 7 is used to push the sliding seat 6 to move.

[0043] The sliding seat 6 is slidably and sealedly connected to a slide plate 11. A second elastic element 12 is provided between the slide plate 11 and the sliding seat 6. Several brush rods 13 are fixedly connected to the slide plate 11. A support component 8 is fixedly connected to the slide plate 11. The support component 8 can provide auxiliary support for all brush rods 13 at the same time. Multiple brush strips 15 are fixedly connected to the support component 8.

[0044] The mechanism groove 5 is provided with a flow guiding mechanism 9, the sleeve 4 can be fixedly connected to a water tank, and the flow guiding mechanism 9 can continuously guide and cool the connection between the brush rod 13 and the threaded steel.

[0045] A temperature sensor is provided on the slide plate 11, which can monitor the temperature of all brush rods 13. The temperature sensor is electrically connected to the support component 8. A pressure sensor is provided at the connection position between the sliding seat 6 and the drive component 7. The pressure sensor is electrically connected to the drive component 7.

[0046] In this embodiment, the rebar is conveyed by a conveying mechanism (an existing structure in the background art), and the refining mechanism 2 rolls the rebar.

[0047] Afterwards, the threaded steel passes through the sleeve 4, and the drive assembly 7 is activated. The drive assembly 7 drives the sliding seat 6 to move out of the mechanism groove 5. At this time, the brush rod 13 moves synchronously. Since the slide plate 11 can slide freely relative to the sliding seat 6, under the push of the drive assembly 7, the slide plate 11 drives the brush rod 13 to abut in the thread groove of the threaded steel. At this time, the brush bar 15 abuts against the outer surface of the threaded steel.

[0048] As the sleeve 4 rotates under electric drive, the brush strip 15 and brush rod 13 work together to thoroughly remove the iron oxide scale from the outer surface of the threaded steel and the inner surface of the thread groove.

[0049] When the temperature of the brush rod 13 is too high, the temperature sensor controls the support assembly 8 to start. The support assembly 8 reduces the limit on the brush rod 13 to avoid generating large friction and excessive frictional heat between the brush rod 13 and the surface of the threaded steel, which would cause the brush rod 13 to be squeezed or deformed by heat.

[0050] When the brush rod 13 is worn too much, the pressure sensor controls the drive assembly 7 to start. The drive assembly 7 pushes the brush rod 13 and the brush strip 15 closer to the threaded steel to ensure the cleaning effect of iron oxide scale on the surface of the threaded steel.

[0051] The flow guiding mechanism 9 can continuously guide and cool the connection between the brush rod 13 and the threaded steel.

[0052] like Figure 7 As shown, in a preferred embodiment of the present invention, the support assembly 8 includes an electric telescopic sleeve 81 and an auxiliary support plate 82. The fixed end of the electric telescopic sleeve 81 is fixedly connected to the slide plate 11, and the telescopic end of the electric telescopic sleeve 81 is fixedly connected to the auxiliary support plate 82. All brush rods 13 are slidably connected to and penetrate the auxiliary support plate 82. The temperature sensor is electrically connected to the electric telescopic sleeve 81, and all brush strips 15 are fixedly connected to the auxiliary support plate 82.

[0053] In this embodiment, the auxiliary support plate 82 limits all brush rods 13 to ensure that the brush rods 13 can effectively contact the threaded steel and ensure the cleaning effect of the brush rods 13 on the iron oxide scale on the surface of the threaded steel.

[0054] When the temperature of the brush rod 13 is too high, the temperature sensor controls the electric telescopic sleeve 81 to start. The electric telescopic sleeve 81 drives the auxiliary support plate 82 to move towards the root of the brush rod 13. The auxiliary support plate 82 reduces the restriction on the brush rod 13, so as to avoid the brush rod 13 and the surface of the threaded steel generating large friction and excessive frictional heat, which would cause the brush rod 13 to be squeezed and deformed or thermally deformed.

[0055] like Figure 5 and Figure 6As shown, in a preferred embodiment of the present invention, the drive assembly 7 includes an electric telescopic rod 71, a push plate 72, and a spring 73; one end of the electric telescopic rod 71 is fixedly connected to the sleeve 4, and the other end of the electric telescopic rod 71 is fixedly connected to the push plate 72; a plurality of springs 73 are provided between the push plate 72 and the sliding seat 6; and the pressure sensor is located at the connection position between the sliding seat 6 and the springs 73.

[0056] In this embodiment, the electric telescopic rod 71 is activated, which pushes the push plate 72. The push plate 72 pushes the sliding seat 6 through the spring 73. The sliding seat 6 squeezes the first elastic element 10. At the same time, the sliding seat 6 drives the brush rod 13 to squeeze the threaded steel. Under the action of the squeezing force, the brush rod 13 moves into the thread groove on the surface of the threaded steel. At this time, the slide plate 11 slides along the sliding seat 6 and squeezes the second elastic element 12.

[0057] like Figure 5 and Figure 6 As shown, in a preferred embodiment of the present invention, the flow guiding mechanism 9 includes a first flow guiding component 91 and a second flow guiding component 92. The sleeve 4 is provided with a sleeve 93 that can communicate with the water tank. The first flow guiding component 91 and the second flow guiding component 92 are both connected between the sleeve 93 and the sliding seat 6. All brush rods 13 are connected to the sliding seat 6. The driving component 7 can control the first flow guiding component 91 to be turned on, and the support component 8 can control the filtration rate in the second flow guiding component 92 to increase. In this embodiment, when the brush rod 13 is worn too much, the pressure sensor controls the driving component 7 to start, and the first flow guiding component 91 is turned on, which increases the cooling effect on the brush rod 13 and the surface of the threaded steel.

[0058] like Figure 6 As shown, in a preferred embodiment of the present invention, the first flow guiding component 91 includes a flow guiding channel 911, a guide hole 912, and a telescopic tube 913; the side wall of the mechanism groove 5 is provided with a flow guiding channel 911 communicating with the sleeve 93, the guide hole 912 is provided on the push plate 72, and the telescopic tube 913 communicates between the guide hole 912 and the sliding seat 6. When the push plate 72 moves vertically to a certain position, the flow guiding channel 911 and the guide hole 912 are connected.

[0059] In this embodiment, when the push plate 72 moves vertically to a certain position, the flow channel 911 and the guide hole 912 are connected, so that the water flows through the sleeve 93, the flow channel 911, the guide hole 912 and the telescopic pipe 913 in sequence, and then the water flows into the sliding seat 6. The water flows through the brush rod 13 to cool the surface of the threaded steel.

[0060] like Figure 5 and Figure 6As shown, in a preferred embodiment of the present invention, the second flow guiding component 92 includes a vertical plate 921, a baffle 922, a conduit 923, and a rubber tube 924; the sliding seat 6 is fixedly connected to the conduit 923, the conduit 923 is connected to the sleeve 93 through the rubber tube 924, one end of the vertical plate 921 is fixedly connected to the auxiliary support plate 82, and the other end of the vertical plate 921 is fixedly connected to the baffle 922. The baffle 922 is disposed in the sliding seat 6, and the baffle 922 abuts against the port of the conduit 923.

[0061] In this embodiment, when the temperature of the brush rod 13 is too high, the temperature sensor controls the electric telescopic sleeve 81 to start. The electric telescopic sleeve 81 drives the auxiliary support plate 82 to move towards the root of the brush rod 13. The auxiliary support plate 82 drives the vertical plate 921 to push the baffle 922. The baffle 922 moves upward, and the outlet of the conduit 923 increases. At this time, the cooling effect of the water flow on the brush rod 13 and the surface of the threaded steel increases.

[0062] like Figure 8 As shown, in a preferred embodiment of the present invention, the end of the brush rod 13 away from the slide plate 11 is provided with a plurality of wire bristles 14, which enhance the cleaning effect on the side wall of the thread groove.

[0063] A rebar finishing process, applied to a rebar finishing machine described in the above embodiments, includes the following steps:

[0064] S1: Steel is heated in a furnace, and after heating, it is processed by a rolling mill in sequence through rough rolling, intermediate rolling and finish rolling to form rebar.

[0065] S2: The conveying mechanism conveys the rebar, and the finishing mechanism 2 rolls the rebar;

[0066] S3: The threaded steel bar passes through the sleeve 4, and the drive assembly 7 drives the sliding seat 6 to move out of the mechanism groove 5. At this time, the brush rod 13 moves synchronously, and the slide plate 11 drives the brush rod 13 to abut in the thread groove of the threaded steel bar. At this time, the brush strip 15 abuts against the outer surface of the threaded steel bar. As the sleeve 4 rotates under the electric drive, the brush strip 15 and the brush rod 13 cooperate to thoroughly remove the iron oxide scale from the outer surface of the threaded steel bar and the inner surface of the thread groove.

[0067] Working principle:

[0068] Steel is heated in a furnace, and after heating, it is processed by a rolling mill in sequence through rough rolling, intermediate rolling and finish rolling to form rebar.

[0069] The rebar is then conveyed by a conveying mechanism (the existing structure in the background art), and the finishing mechanism 2 rolls the rebar.

[0070] Afterwards, the rebar passes through the sleeve 4, and the drive assembly 7 is activated. The drive assembly 7 drives the sliding seat 6 to move out of the mechanism groove 5, and the brush rod 13 moves synchronously. Since the slide plate 11 can slide freely relative to the sliding seat 6, under the push of the drive assembly 7, the slide plate 11 drives the brush rod 13 to abut in the thread groove of the rebar. At this time, the brush strip 15 abuts against the outer surface of the rebar. As the sleeve 4 rotates under electric drive, the brush strip 15 and the brush rod 13 cooperate to thoroughly remove the iron oxide scale from the outer surface of the rebar and the inner surface of the thread groove.

[0071] When the temperature of the brush rod 13 is too high, the temperature sensor controls the electric telescopic sleeve 81 to start. The electric telescopic sleeve 81 drives the auxiliary support plate 82 to move towards the root of the brush rod 13. The auxiliary support plate 82 reduces the restriction on the brush rod 13, so as to avoid the brush rod 13 and the threaded steel surface generating large friction force and excessive frictional heat, which would cause the brush rod 13 to be squeezed and deformed or thermally deformed.

[0072] At this time, the auxiliary support plate 82 drives the vertical plate 921 to push the baffle 922. The baffle 922 moves upward, the outlet of the guide tube 923 increases, and the cooling effect of the water flow on the brush rod 13 and the surface of the threaded steel increases, further preventing the brush rod 13 from thermal deformation.

[0073] When the brush rod 13 is worn too much, the pressure sensor controls the electric telescopic rod 71 to extend. The electric telescopic rod 71 pushes the push plate 72, and the push plate 72 pushes the sliding seat 6 through the spring 73. The sliding seat 6 drives the brush rod 13 and the brush strip 15 to approach the threaded steel, ensuring the cleaning effect of iron oxide scale on the surface of the threaded steel.

[0074] When the push plate 72 moves vertically to a certain position, the flow channel 911 and the guide hole 912 are connected, so that the water flows through the sleeve 93, the flow channel 911, the guide hole 912 and the telescopic pipe 913 in sequence. Then the water flows into the sliding seat 6. The water flows through the brush rod 13 to cool the surface of the threaded steel, so as to avoid the brush rod 13 and the brush strip 15 from being too tightly pressed against the threaded steel and generating a lot of frictional heat.

[0075] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0076] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

At this time, the brush rod (13) moves synchronously, and the slide plate (11) drives the brush rod (13) to abut against the thread groove of the threaded steel. At this time, the brush strip (15) abuts against the outer surface of the threaded steel. As the sleeve (4) rotates under the electric drive, the brush strip (15) and the brush rod (13) work together to thoroughly remove the iron oxide scale from the outer surface of the threaded steel and the inner surface of the thread groove.
