Description

Technical Field

[0001] This utility model relates to the technical field of petroleum equipment remanufacturing, and in particular to a hot rolling device for remanufacturing waste sucker rods. Background Technology

[0002] A hot rolling mill is a device that heats and mechanically rolls metal billets to form them into the required shapes and sizes. It mainly consists of a heating furnace, a rolling mill, a cooling device, a traction system, and a shearing machine. The metal billet is first heated to a plastic state in the heating furnace, and then rolled multiple times through multiple rolls to gradually reduce its thickness and improve its surface quality. Finally, it is cooled to a suitable hardness by the cooling device. The entire process requires a highly efficient automated control system to ensure product quality and production efficiency, while also having comprehensive safety protection measures.

[0003] A search revealed an existing patent (publication number: CN222643760U) that discloses a hot-rolled steel bar production device, including a slitting mechanism and a grinding mechanism. The slitting mechanism includes a worktable, a conveying assembly, a slitting assembly, and a positioning assembly. A telescopic rod assembly is provided at the lower part of the worktable for supporting the rear end of the hot-rolled steel bar. This device can support both ends of the hot-rolled steel bar, simplify the slitting process, and grind burrs at the cut edges of the steel bar.

[0004] However, in the above scheme, the hot rolling process results in poor adaptability of the equipment when handling columns of different specifications because it is hot rolled on a single size column. This limits its application in diverse production needs. In order to improve the applicability of the equipment, it is possible to introduce an adjustable roll or die system so that the equipment can be flexibly adjusted according to the different sizes of the column.

[0015] In a preferred embodiment of the hot rolling device for remanufacturing waste sucker rods according to this utility model, the cleaning component includes a servo motor, which is fixedly connected to the surface of a fixed plate on one side. The output end of the servo motor is fixed to a bidirectional lead screw through the fixed plate via a coupling. The surface of the bidirectional lead screw is symmetrically provided with bases. A sprayer body is provided on one side of the base. A limit rod passes through one side of the two bases along their length direction.

Detailed Implementation

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0030] Example 1

[0031] Reference Figures 1-3 This is the first embodiment of the present invention, which provides a hot rolling device for remanufacturing waste sucker rods. The hot rolling device for remanufacturing waste sucker rods includes two fixed plates 1 arranged opposite to each other. A housing 2 is fixed to the outer side of one fixed plate 1. The symmetrically arranged fixed plates 1 provide a stable support structure. The housing 2 integrates a drive component and has a compact layout. A worm body 4 is provided at the transverse center position of the inner wall of the housing 2. The worm body 4 is controlled to rotate by a drive motor 3. Worm wheel bodies 5 are provided on the upper and lower sides of the worm body 4 and mesh with it for transmission. A connecting rod 6 is fixed to the side of the worm wheel body 5 near the fixed plate 1.

[0032] Two fixed plates 1 are symmetrically provided with adjustable roll assemblies 7 on their inner sides. Two connecting rods 6 are fixedly connected to the fixed plates 1 and the corresponding adjustable roll assemblies 7 at one end. The meshing transmission of the worm gear 4 and the worm wheel 5 realizes efficient power transmission and links the adjustable roll assemblies 7 through the connecting rods 6 to ensure synchronous adjustment.

[0033] A cleaning component 8 is provided on the upper part of the inner side of the two fixed plates 1, and a scraper component 9 is provided at the symmetrical position of the cleaning component 8 along the vertical axis of symmetry of the fixed plates 1;

[0034] Two fixed plates 1 are provided with conveying mechanisms 10 on their inner sides and at their ends away from the adjustable roll assembly 7.

[0035] The adjustable roll assembly 7 includes two opposing columns 701. The columns 701 are rotatably connected to the inner side of the fixed plate 1. A pin block 702 is slidably connected to the inner side of the surface of the column 701. The quick assembly and disassembly of the roll body 705 is achieved through the slidably connected pin block and square block 703, which facilitates maintenance or replacement. A square block 703 is fixed to one end of the pin block 702 near the column 701, and a connecting screw 704 is fixedly connected to the column 701 at the other end of the pin block 702 away from the square block 703. The roll body 705 is located on the opposing inner side of the two columns 701. A columnar block 706 is fixed to both ends of the roll body 705. Vertically arranged connecting springs 708 are symmetrically arranged on the inner wall of the column 701. A limit block 709 is fixed to one end of the connecting spring 708. During the process of the limit block 709 limiting the columnar block 706, the connecting spring 708 is in a stretched state. A sliding rod 711 is fixed to one side of the limit block 709 through a connecting rod.

[0036] The two columns 701 have grooves 707 on their inner sides. The sides of the pin block 702 and the cylindrical block 706 fit against the inner side of the groove 707. The pin block 702 and the cylindrical block 706 are slidably connected to the inner side of the groove 707. The groove design allows the roll body 705 to be adjusted and replaced laterally to adapt to the processing needs of sucker rods of different diameters.

[0037] Two limiting blocks 709 have square holes 710 on one end surface near the pin block 702. The square block 703 and the limiting block 709 form a locking structure through the square hole 710. The cooperation between the square block 703 and the square hole 710 makes the limiting block 709 more stable in limiting the cylindrical block 706.

[0038] An arc-shaped groove 712 is provided on one side of the two columns 701 that are separated from each other. The surface of the slide rod 711 is in contact with the inner side of the arc-shaped groove 712. The slide rod 711 is slidably connected to the inner side of the arc-shaped groove 712. The slide rod slides along the arc-shaped groove to facilitate the adjustment of the position of the limiting block 709.

[0039] Example 2

[0040] Reference Figures 1-5This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: the cleaning component 8 includes a servo motor 801, which is fixedly connected to the surface of a fixing plate 1 on one side. The output end of the servo motor 801 is fixed to a bidirectional lead screw 802 through the fixing plate 1 via a coupling. The surface of the bidirectional lead screw 802 is symmetrically provided with a base 803. A sprayer body 804 is provided on one side of the base 803. A limit rod 805 passes through one side of the two bases 803 along its length direction. The two ends of the limit rod 805 are fixedly connected to the opposite inner sides of the two fixing plates 1. The bidirectional lead screw 802 drives the sprayer 804 to move, thereby achieving comprehensive cleaning of the residue on the surface of the roll. The sprayer 804 is always facing the roll body 705.

[0041] The two bases 803 move in opposite directions along the length of the bidirectional lead screw 802. The limiting rod 805 limits the bases 803 and ensures that the sprayer's movement trajectory is stable, avoiding deviation.

[0042] The scraper assembly 9 includes a fixing rod 901, which is fixed to the inner sides of two fixing plates 1. A scraper body 902 is fixed to the surface of the fixing rod 901. The scraper body 902 has multiple equally spaced circular holes 903 on its surface. The obliquely arranged scraper 902 is in contact with the surface of the roll, effectively removing attached impurities. The multiple circular holes 903 effectively increase the surface area of ​​the scraper 902, which is beneficial to improving the heat dissipation efficiency of the scraper 902.

[0043] The scraper body 902 is obliquely positioned close to the roll body 705, with an inclination angle of 45° to 60°. One end of the scraper body 902 close to the roll body 705 is in contact with the surface of the roll body 705. The 45° to 60° angle design of the scraper body 902 optimizes the contact angle between the scraper body 902 and the roll body 705, reduces scraping resistance, and extends the service life of the scraper body 902.

[0044] The remaining structure is the same as that in Example 1.

[0045] Based on embodiments 1-2, the working principle of this utility model is as follows: the heated sucker rod is conveyed by the conveying mechanism 10. When the sucker rod is conveyed to the inner side of the fixed plate 1, the drive motor 3 drives the worm body 4 to drive the two worm wheel bodies 5 to rotate in opposite directions, and the adjustable roller assembly 7 is driven by the connecting rod 6 to perform hot rolling on the sucker rod.

[0046] Before hot rolling, the user can replace and adjust the adjustable roll assembly 7 according to different sucker rod sizes. By removing the connecting screw 704, the pin block 702 can be pulled out laterally from the inside of the column 701. After the square block 703 on the pin block 702 disengages from the locking block 709, the connecting spring 708 pulls the locking block 709 to reset. Then, the roll body 705 is removed by sliding the column block 706 along the inside of the slide groove 707. Then, the roll body 705 of the corresponding size is replaced. The locking block 709 is slid vertically by sliding the slide rod 711 on the inside of the arc groove 712. Then, the pin block 702 is inserted so that the square block 703 engages with the square hole 710 again. The pin block 702 and the column 701 are connected by the connecting screw 704.

[0047] During the hot rolling process, the servo motor 801 drives the bidirectional lead screw 802 to rotate, which in turn drives the two bases 803 to reciprocate relative to or repulsively. The limit rod 805 limits the bases 803 to prevent them from rotating with the bidirectional lead screw 802. The sprayer body 804 cleans and cools the roll body 705, and water is supplied to the sprayer body 804 through an external water pipe.

[0048] Meanwhile, the scraper body 902 installed on the fixing rod 901 can scrape the surface of the roll body 705 to prevent residue from accumulating on the surface of the roll body 705.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
