Description

Technical Field

[0001] This utility model relates to the field of rolling equipment technology, specifically a rebar rolling equipment. Background Technology

[0002] Rebar is the common name for hot-rolled ribbed steel bars. The grade of ordinary hot-rolled steel bars is composed of HRB and the minimum yield point of the grade. There are two common classification methods for rebar: one is classification by geometric shape, which is based on the cross-sectional shape of the transverse ribs and the different spacing of the ribs; the other is classification by performance (grade). The specifications of rebar should generally include the standard grade (type code), nominal diameter, nominal weight (mass), specified length, and the allowable tolerance values ​​of the above indicators.

[0003] In the production process of rebar, a rebar rolling equipment is required to roll threads onto the surface of the rebar.

[0004] An investigation revealed that a Chinese utility model patent discloses a rebar rolling equipment (publication number: CN219151159U), comprising a base and upper and lower rollers located within the base. Pressure rollers are symmetrically arranged within the base for feeding the rebar. A housing is fixedly connected within the base, and conveying units are symmetrically arranged within the housing. Second rollers are symmetrically rotatably connected within the housing, and cleaning brushes are uniformly fixedly connected to the second rollers. Two second rollers are respectively configured to correspond to two conveying units. First gears are fixedly connected to the corresponding conveying units and the corresponding second rollers. The two first gears are connected by a first gear-type conveyor belt. This utility model, through the coordinated use of the conveyor belt, sliding plate, and cleaning brushes, can improve the straightness of the rebar after rolling, and simultaneously drive the cleaning brushes to remove burrs generated during rolling, without requiring additional power.

[0005] Although the aforementioned patent, through the design of structures such as conveyor belts, can improve the straightness of the reinforcing bars after they have been pressed, and can also drive cleaning brushes to remove the burrs generated during the pressing process, without requiring additional power, the production process of rebar requires heating the raw material. This causes the raw material to produce a layer of iron oxide scale on its surface when it enters each rolling mill during the rolling process. As a result, the surface of the rolling rolls will be covered with the iron oxide scale, which will come into contact with the raw material during the rolling process. This iron oxide scale will affect the quality of the rebar and the processing of the raw material by the rolling mill.

[0006] Therefore, this utility model provides a rebar rolling equipment to solve the above problems. Utility Model Content

[0007] This utility model provides a rebar rolling equipment, which aims to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a rebar rolling equipment, including a rolling shell, a rolling mechanism installed inside the rolling shell, and a discharge mechanism installed on one side wall of the rolling shell;

[0009] The material discharge mechanism includes two fixed plates fixedly connected to the inner wall of the rolling shell. A first scraper plate is fixedly connected to one side of the two fixed plates. Connecting rods are fixedly connected to both sides of the lower surface of the first scraper plate. A second scraper plate is fixedly connected to one end of the two connecting rods.

[0010] The discharge mechanism also includes a conveyor belt rotatably connected inside the rolling housing. Rotating rods are sleeved on both sides inside the conveyor belt. An inclined plate is rotatably connected to the surface of one of the rotating rods through a bearing seat. The inclined plate is fixedly connected to the rolling housing. The conveyor belt corresponds to the first scraper and the second scraper.

[0011] As a preferred technical solution of this application, the discharge mechanism further includes a mounting plate rotatably connected to another rotating rod via a bearing seat. A cleaning plate is fixedly connected to one side of the mounting plate, and the cleaning plate is in contact with the conveyor belt. A discharge trough is provided on one side of the rolling shell, and the mounting plate is fixedly connected to the inner bottom wall of the discharge trough.

[0012] As a preferred technical solution of this application, the discharge mechanism further includes a collection box that is fixedly connected to one side of the rolling shell by bolts. A sealing plate is slidably connected inside the collection box, and a threaded rod is threadedly connected to the surface of the sealing plate. A drive motor is fixedly connected to one end of the threaded rod, and the drive motor is fixedly connected to the rolling shell.

[0013] As a preferred technical solution of this application, the rolling mechanism includes two rolls that are rotatably connected to the inside of the rolling housing via bearing seats. The first scraper and the second scraper are respectively attached to the corresponding rolls, and one of the rolls is connected to the rotating rod via a belt.

[0014] As a preferred technical solution of this application, the rolling mechanism further includes a guide tube fixedly connected to the lower surface of the first scraper plate. One side of the guide tube is fixedly connected to a limit rod in a circular array. A grinding cylinder is rotatably sleeved on the surface of several limit rods. A linkage gear is fixedly connected to the surface of the grinding cylinder.

[0015] As a preferred technical solution of this application, the rolling mechanism further includes a drive gear fixedly connected to the linkage gear and meshing with it. A servo motor is fixedly connected to the surface of the drive gear. The servo motor is fixedly connected to the rolling housing. The two rolls are connected by belt drive. One end of one of the rolls is fixedly connected to a DC motor 15 fixedly connected to the rolling housing.

[0016] The beneficial effects of this utility model are:

[0017] Through the cooperation of the feeding mechanism and the rolling mechanism, the steel raw material is inserted into the inside of the rolling shell. The rolling mechanism rolls the steel raw material. The first scraper and the second scraper cooperate to scrape the surface of the two rolls, thereby avoiding the iron oxide scale layer from affecting the rolls. At the same time, the scraped iron oxide scale layer falls onto the conveyor belt. The rolls drive the conveyor belt to move, so that the conveyor belt discharges the iron oxide scale layer through the discharge chute, avoiding the iron oxide scale layer from causing secondary impact on the rolling mechanism.

[0018] With the setting of mechanisms such as the rolling mechanism, the cleaning plate cleans the surface of the conveyor belt when the conveyor belt rotates, thereby preventing the conveyor belt from bringing the attached iron oxide scale back into the interior of the rolling shell. At the same time, the setting of the drive motor causes the threaded rod to drive the sealing plate to disengage from the collection box, so that the iron oxide scale moves out with the sealing plate, which facilitates the treatment of the iron oxide scale.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a rebar rolling equipment, such as... Figure 1 - Figure 5 As shown, the rebar rolling equipment includes a rolling housing 1, inside which a rolling mechanism is installed. The rolling mechanism includes two rollers 16 that are rotatably connected to the inside of the rolling housing 1 via bearing seats. A first scraper 3 and a second scraper 5 are respectively attached to the corresponding rollers 16. The two rollers 16 are connected by a belt drive. One end of one of the rollers 16 is fixedly connected to a DC motor 15 that is fixedly connected to the rolling housing 1. When the steel raw material is inserted into the inside of the rolling housing 1, the DC motor 15 is started, and the two rollers 16 are rotated synchronously via the belt to process threads on the surface of the steel raw material.

[0028] One of the rolls 16 is connected to the rotating rod 7 via a belt. The rolling mechanism also includes a guide tube 17 fixedly connected to the lower surface of the first scraper plate 3. One side of the guide tube 17 is fixedly connected to a limit rod 18 in a ring array. The surfaces of several limit rods 18 are rotatably sleeved with a grinding cylinder 19. The guide tube 17 guides and straightens the threaded steel, so that the threaded steel is inserted into the inside of the grinding cylinder 19.

[0029] A linkage gear 20 is fixedly connected to the surface of the grinding cylinder 19. The rolling mechanism also includes a drive gear 21 that is fixedly connected to the linkage gear 20 and meshes with it. A servo motor 22 is fixedly connected to the surface of the drive gear 21. The servo motor 22 is fixedly connected to the rolling housing 1. When the servo motor 22 is started, its output end drives the drive gear 21 to rotate, thereby driving the linkage gear 20 to rotate, so that the grinding cylinder 19 rotates on the surface of the threaded steel, grinding the surface of the threaded steel and improving the quality of the threaded steel.

[0030] A discharge mechanism is installed on one side wall of the rolling shell 1. The discharge mechanism includes two fixed plates 2 fixedly connected to an inner wall of the rolling shell 1. A first scraper 3 is fixedly connected to one side of the two fixed plates 2. Connecting rods 4 are fixedly connected to both sides of the lower surface of the first scraper 3. A second scraper 5 is fixedly connected to one end of the two connecting rods 4. The surfaces of the two rolls 16 are cleaned by the first scraper 3 and the second scraper 5, so that the iron oxide scale layer will not affect the rolls 16 when processing threaded steel.

[0031] The discharge mechanism also includes a conveyor belt 6 rotatably connected inside the rolling housing 1. Rotating rods 7 are sleeved on both sides inside the conveyor belt 6. An inclined plate 8 is rotatably connected to the surface of one of the rotating rods 7 through a bearing seat. The inclined plate 8 is fixedly connected to the rolling housing 1. The conveyor belt 6 corresponds to the first scraper 3 and the second scraper 5. The discharge mechanism also includes a mounting plate 13 rotatably connected to another rotating rod 7 through a bearing seat. A cleaning plate 14 is fixedly connected to one side of the mounting plate 13. The cleaning plate 14 is in contact with the conveyor belt 6. A discharge chute is opened on one side of the rolling housing 1. The scraped iron oxide scale layer is conveyed by the conveyor belt 6. The roller 16 drives the conveyor belt 6 to rotate, so that the iron oxide scale layer is discharged through the discharge chute. The cleaning plate 14 cleans the surface of the conveyor belt 6.

[0032] The mounting plate 13 is fixedly connected to the inner bottom wall of the discharge chute. The discharge mechanism also includes a collection box 9 fixedly connected to one side of the rolling shell 1 by bolts. A sealing plate 10 is slidably connected inside the collection box 9. A threaded rod 11 is threadedly connected to the surface of the sealing plate 10. A drive motor 12 is fixedly connected to one end of the threaded rod 11. The drive motor 12 is fixedly connected to the rolling shell 1. After the threaded steel is processed, the drive motor 12 is started, and its output end drives the threaded rod 11 to rotate, so that the sealing plate 10 is separated from the collection box 9, thereby allowing the discharged iron oxide scale layer to move out with the sealing plate 10, which facilitates the subsequent treatment of the iron oxide scale layer.

[0033] Specifically, when this rebar rolling equipment is in use: the steel raw material is inserted into the inside of the rolling shell 1, the DC motor 15 is started, and the two rollers 16 are rotated synchronously through the belt to process threads on the surface of the steel raw material. The threaded steel is guided and straightened through the guide tube 17, so that the threaded steel is inserted into the inside of the grinding cylinder 19. The servo motor 22 is started, and its output end drives the drive gear 21 to rotate, which in turn drives the linkage gear 20 to rotate, so that the grinding cylinder 19 rotates on the surface of the threaded steel to grind the surface of the threaded steel and improve the quality of the threaded steel.

[0034] When processing rebar, the surfaces of the two rolls 16 are cleaned by the first scraper 3 and the second scraper 5, so that the iron oxide scale layer will not affect the rolls 16 when processing rebar. The scraped iron oxide scale layer is transported by the conveyor belt 6. The rolls 16 drive the conveyor belt 6 to rotate, so that the iron oxide scale layer is discharged through the discharge chute. The surface of the conveyor belt 6 is cleaned by the cleaning plate 14 to prevent the conveyor belt 6 from bringing the attached iron oxide scale layer into the interior of the rolling shell 1.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
