Description

Technical Field

[0001] This invention relates to the field of high-performance threaded steel fine rolling processing, specifically to a high-performance threaded steel fine rolling processing apparatus and its processing technology. Background Technology

[0002] In the production of rebar, rolling is the core process. During rolling, the steel billet is fed into the rolling mill and undergoes multiple rolling and drawing processes to finally become rebar with a diameter of 6-50mm. The rolling process requires controlling parameters such as rolling temperature, rolling speed, and rolling force to ensure the dimensional accuracy and mechanical properties of the rebar. However, in existing rolling processes, heated billets are typically rolled using rolling equipment, followed by embossing operations using an embossing mechanism to ultimately form the rebar. This manufacturing process requires two separate steps: rolling and embossing. Because these two steps cannot be performed simultaneously, the overall process efficiency in rebar production may be low, thus failing to meet current requirements. Therefore, we propose a high-performance rebar precision rolling processing device and its processing technology. Summary of the Invention

[0003] The purpose of this invention is to provide a high-performance rebar fine rolling processing device and its processing technology to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a high-performance rebar fine rolling processing device, comprising a first heat-insulating conveyor belt, a heating boiler provided on one side of the first heat-insulating conveyor belt, a rolling mechanism provided on one side of the first heat-insulating conveyor belt, a base plate fixedly connected to the lower end of the rolling mechanism, an embossing mechanism provided on one side of the rolling mechanism, a second heat-insulating conveyor belt provided on one side of the embossing mechanism, and a cooling pool provided on one side of the second heat-insulating conveyor belt.

[0005] Preferably, the rolling mechanism includes two hydraulic push rods fixed to the upper sides of the base plate, and the upper ends of the two hydraulic push rods are connected to horizontal support plates. Three fixing plates are vertically arranged and fixed between the two horizontal support plates. The three fixing plates are movable on the upper side of the bottom end. A vertical support plate is fixedly connected between each pair of adjacent fixing plates. Side pressure plates are fixedly connected to both sides of the fixing plates. A feed port is fixedly connected to the upper end of the fixing plates. A rolling cylinder is fixedly connected to one side of the feed port. The diameter of the three rolling cylinders decreases sequentially from top to bottom.

[0006] Preferably, the three side pressure plates are arranged in a staggered manner from top to bottom, with the stagger between two adjacent side pressure plates being five centimeters.

[0007] Preferably, the side pressure plate is disc-shaped, and both the upper and lower ends of the side pressure plate are provided with inclined surfaces.

[0008] Preferably, the embossing mechanism includes a slow-speed motor, a rotating shaft on one side of the slow-speed motor is connected to a rotating column via a coupling, four rotating columns are arranged on the rotating column, a spring is connected between each pair of adjacent rotating columns, a rotating disk is fixedly connected around the rotating column, through holes are provided on both the upper and lower sides of the rotating disk, an embossing block is provided on one side of the rotating disk, and a bearing bracket is supported at one end of the rotating column.

[0009] Preferably, push rods are connected to the through holes on the three rotating disks near the bearing bracket, and the three push rods slide relative to each other.

[0010] Preferably, each of the rotating sleeves is provided with an inner annular groove, and the spring is fixedly connected to the inner annular groove.

[0011] Preferably, a cross groove is provided through the middle of the rotating sleeve, the cross section of the rotating column is cross-shaped, and the rotating column is inserted laterally into the cross groove.

[0012] Preferably, the cross-section of one end of each of the three push rods is a triangular face, and the upper and lower ends of the side pressure plate are movably fitted with the triangular inclined face of one end of the push rod.

[0013] A processing technology for a high-performance threaded steel fine rolling processing device, the processing technology includes the following steps:

[0014] Step A: The heating furnace heats the cylindrical steel billet that needs to be heated until it softens. Then, the cylindrical steel billet is transported and moved by the first heat-insulated conveyor belt, so that the first heat-insulated conveyor belt moves the heated cylindrical steel billet into the feed inlet.

[0015] Step B: Next, the output end of the hydraulic push rod can drive the horizontal support plates on both sides of the fixed plate to move vertically, which makes one of the three vertically arranged fixed plates aligned with the transport plane of the first heat-insulating conveyor belt, thereby moving the cylindrical steel billet on the first heat-insulating conveyor belt into the feed inlet.

[0016] Step C: Since side pressure plates are fixedly connected to both sides of the fixed plate, when the entire fixed plate moves, the side pressure plates also move. The side pressure plates move to the side of the push rod and press it against the side of the bearing bracket, thereby causing each rotating disk to move and thus adjusting the distance between each rotating disk.

[0017] Step D: Then turn on the slow speed motor switch, so that the rotating shaft of the slow speed motor drives the rotating column on one side to rotate, and the rotating column drives the rotating disks welded on the four rotating sleeves to rotate.

[0018] Step E: After the cylindrical steel billet moves into the feed inlet, the rolling cylinder at the front end of the fixed plate squeezes the cylindrical steel billet, so that the cylindrical steel billet can be squeezed into the size of the rolling cylinder aperture. At the same time, when the cylindrical steel billet is squeezed and rolled out from the rolling cylinder, the rotation of the rotating disk drives the embossing block to squeeze both sides of the cylindrical steel billet, thereby forming embossing on the surface of the cylindrical steel billet and pressing it into rebar. Finally, the rebar is transported to the cooling pool for cooling by the second heat-insulated conveyor belt.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. In this invention, the output end of the hydraulic push rod can drive the horizontal support plates on both sides of the fixed plate to move vertically. This aligns one of the three vertically arranged fixed plates with the transport plane of the first heat-insulating conveyor belt, thereby moving the cylindrical steel billet on the first heat-insulating conveyor belt into the feed inlet. After the cylindrical steel billet moves into the feed inlet, the rolling cylinder at the front end of the fixed plate extrudes the cylindrical steel billet, extruding it to the size of the rolling cylinder aperture. At the same time, the rotation of the rotating disk drives the embossing block to extrude the two sides of the cylindrical steel billet, thereby forming embossing on the surface of the cylindrical steel billet and pressing it into rebar. This arrangement allows the cylindrical steel billet to be embossed on its surface during the extrusion molding process, thus saving the rebar rolling process, saving production time, and improving production efficiency.

[0021] 2. In this invention, one end of each of the three push rods is fixedly connected to a through hole on the rotating disk. The push rods are fixedly connected to the rotating disk, thus pushing the rotating disk fixedly connected to one side. The tension of the spring is pulled by the push rod, which in turn increases the distance between the four rotating disks. This adjusts the distance between each rotating disk. With this arrangement, the first heat-insulating conveyor belt moves the cylindrical steel billet into the rotating sleeve of the rotating column. While the rotating sleeve of the rotating column extrudes the heated cylindrical steel billet, the displacement of the side pressure plate adjusts the distance between each rotating disk. The distance between the side pressure plate and the push rod is different for each diameter of the rolling cylinder, resulting in different displacements of each side pressure plate on the three rotating disks. As a result, the final rebar has different embossing distances on its surface due to its different diameter. Attached Figure Description

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0032] [0 Please see] Figures 1 to 8 An embodiment of the present invention provides a high-performance rebar fine rolling processing device, comprising a first heat-insulating conveyor belt 1, a heating boiler on one side of the first heat-insulating conveyor belt 1, a rolling mechanism 2 on one side of the first heat-insulating conveyor belt 1, a base plate fixedly connected to the lower end of the rolling mechanism 2, an embossing mechanism 3 on one side of the rolling mechanism 2, a second heat-insulating conveyor belt 4 on one side of the embossing mechanism 3, and a cooling pool 5 on one side of the second heat-insulating conveyor belt 4.

[0033] The rolling mechanism 2 includes two hydraulic push rods 205 fixed to the upper sides of the base plate respectively. The upper ends of the two hydraulic push rods 205 are connected to horizontal support plates 204. Three fixed plates 203 are arranged vertically between the two horizontal support plates 204. A vertical support plate 207 is fixedly connected between each pair of adjacent fixed plates 203. Side pressure plates 206 are fixedly connected to both sides of the fixed plates 203. A feed inlet 201 is fixedly connected to the upper end of the fixed plates 203. A rolling cylinder 202 is fixedly connected to one side of the feed inlet 201.

[0034] The embossing mechanism 3 includes a slow-speed motor 303. A rotating shaft on one side of the slow-speed motor 303 is connected to a rotating column 307 via a coupling. Four rotating sleeves 302 are arranged on the rotating column 307. A spring 305 is connected between each pair of adjacent inner ring grooves 306. A rotating disk 301 is fixedly connected around the rotating sleeve 302. Through holes 308 are provided horizontally on both the upper and lower sides of the rotating disk 301. An embossing block 310 is provided on one side of the rotating disk 301. A bearing bracket 309 is supported at one end of the rotating column 307. The rotating shaft on one side of the slow-speed motor 303 can drive the rotating column 307 to rotate, thereby driving the rotating sleeves 302 to rotate.

[0035] Push rods 304 are connected to the through holes 308 on the three rotating disks 301 near the bearing bracket 309. The three push rods 304 slide against each other. An inner ring groove 306 is fixed on each rotating sleeve 302. A spring 305 is connected in the inner ring groove 306. A cross groove 311 is provided through the middle of the rotating sleeve 302. The cross section of the rotating column 307 is cross-shaped. The rotating column 307 is inserted laterally into the cross groove 311. The cross-shaped cross section of the rotating column 307 and the cross groove 311 improve the insertion connection between the rotating sleeve 302 and the rotating column 307, so that the rotating column 307 drives the entire rotating sleeve 302 to rotate during the rotation.

[0036] The cut surface of one end of the push rod 304 is a triangular face. The diameter of the three rolling cylinders 202 decreases from top to bottom. The three side pressure plates 206 are staggered from top to bottom. The two adjacent side pressure plates 206 are staggered by five centimeters. The side pressure plates 206 are disc-shaped. Both the upper and lower ends of the side pressure plates 206 are provided with inclined surfaces. When the hydraulic push rod 205 moves up and down, the upper and lower ends of the side pressure plates 206 and the triangular inclined surface of one end of the push rod 304 move in conjunction, so that the vertical movement of the side pressure plates 206 pushes the push rod 304 laterally. Since each pair of adjacent rotating sleeves 302 are connected by springs 305.

[0037] One end of each of the three push rods 304 is fixedly connected to the through hole 308 on the rotating disk 301. The push rods 304 are fixedly connected to the rotating disk 301, so that the push rods 304 push the rotating disk 301 fixedly connected on one side. The tension of the spring 305 is pulled by the push rods 304, which causes the distance between the four rotating disks 301 to increase continuously. This adjusts the distance between each rotating disk 301. With this setting, the first heat-insulating conveyor belt 1 moves the cylindrical steel billet into the rotating sleeve 302. While the rotating sleeve 302 extrudes the heated cylindrical steel billet, the displacement of the side pressure plate 206 adjusts the distance between each rotating disk 301. The distance between the side pressure plate 206 and the push rod 304 is different for each diameter of the rolling cylinder 202. This results in different displacements of each side pressure plate 206 on the three rotating disks 301. Finally, the distance of the surface embossing of the rebar is different due to the different diameters.

[0038] The output end of the hydraulic push rod 205 can drive the horizontal support plates 204 on both sides of the fixed plate 203 to move vertically. This aligns one of the three vertically arranged fixed plates 203 with the transport plane of the first heat-insulating conveyor belt 1, thereby moving the cylindrical steel billet on the first heat-insulating conveyor belt 1 into the feed inlet 201. After the cylindrical steel billet moves into the feed inlet 201, the rolling cylinder 202 at the front end of the fixed plate 203 extrudes the cylindrical steel billet, so that the cylindrical steel billet can be extruded to the size of the diameter of the rolling cylinder 202. At the same time, the rotation of the rotating disk 301 drives the embossing block 310 to extrude the two sides of the cylindrical steel billet, thereby forming embossing on the surface of the cylindrical steel billet and pressing it into threaded steel. This setting allows the cylindrical steel billet to be embossed on its surface during the extrusion forming process, thereby saving the threaded steel rolling process, saving production time, and improving production efficiency.

[0039] A processing technology for a high-performance threaded steel fine rolling processing device includes the following steps:

[0040] Step A: The heating furnace heats the cylindrical steel billet that needs to be heated until it is soft. Then, the cylindrical steel billet is transported and moved by the first heat-insulating conveyor belt 1, so that the first heat-insulating conveyor belt 1 moves the heated cylindrical steel billet into the feed inlet 201.

[0041] Step B: Next, the output end of the hydraulic push rod 205 can drive the horizontal support plates 204 on both sides of the fixed plate 203 to move vertically, which makes one of the three vertically arranged fixed plates 203 aligned with the transport plane of the first heat-insulating conveyor belt 1, thereby moving the cylindrical steel billet on the first heat-insulating conveyor belt 1 into the feed inlet 201.

[0042] Step C: Since side pressure plates 206 are fixedly connected to both sides of the fixed plate 203, when the entire fixed plate 203 moves, the side pressure plates 206 also move. The side pressure plates 206 move to the side of the push rod 304 and press it against the side of the bearing bracket 309, thereby causing each rotating disk 301 to move, thereby adjusting the distance between each rotating disk 301.

[0043] Step D: Then turn on the slow motor 303 switch, so that the rotating shaft of the slow motor 303 drives the rotating column 307 on one side to rotate, and the rotating column 307 drives the rotating disks 301 welded on the four rotating sleeves 302 to rotate.

[0044] Step E: After the cylindrical steel billet moves into the feed inlet 201, the rolling cylinder 202 at the front end of the fixed plate 203 extrudes the cylindrical steel billet, so that the cylindrical steel billet can be extruded into the size of the rolling cylinder 202 aperture. At the same time, when the cylindrical steel billet is extruded and rolled out from the rolling cylinder 202, the rotation of the rotating disk 301 drives the embossing block 310 to extrude the two sides of the cylindrical steel billet, thereby forming embossing on the surface of the cylindrical steel billet and pressing it into rebar. Finally, the rebar is transported to the cooling pool 5 for cooling by the second heat-insulating conveyor belt 4.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
