Abstract
Description
Technical Field
[0001] This utility model relates to the field of rolling equipment technology, and in particular to a front-hole type rolling equipment for round steel finished products. Background Technology
[0002] Rolling equipment typically includes components such as rolling mills, rollers, dies, or roller conveyors. It is a processing method that uses rolling mills to process metal billets through a series of rollers to achieve the required dimensions, shape, and surface quality. It can roll round holes, square holes, elliptical holes, rectangular holes, hexagonal holes, and convex holes. These different types of hole shapes can be selected according to actual needs to achieve different functions such as connection, positioning, ventilation, aesthetics, or weight reduction.
[0003] During the rolling process of round steel, multiple round holes are punched at the same cross section for installation with other structural components. The cylindrical steel is transported by rollers, which makes it inconvenient to adjust the position of the cylindrical steel when rolling at the same cross section. To address this issue, we propose a pre-hole type rolling device for finished round steel to solve the existing problems. Utility Model Content
[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a pre-rolling device for round steel products.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a round steel finished product front-hole type rolling device, including a frame, a ring seat, a rolling hydraulic rod one, a mounting ring, and a rolling hydraulic rod two. The ring seat is sleeved on the outer side of the frame, and a mounting ring is provided on the inner wall of the ring seat. A rotating ring is rotatably installed inside the ring seat on the outer wall of the mounting ring. A gear ring is sleeved on the outer wall of the rotating ring. A motor one is provided at the upper end of the ring seat, and a gear that meshes with the gear ring is provided at the output end of the motor one. A mounting seat is provided on the inner wall of the mounting ring, and a rolling hydraulic rod two is provided at the lower end of the mounting seat. A rolling head two is provided below the rolling hydraulic rod two. Two sets of equidistantly distributed conveying rollers are rotatably installed inside the frame. A lifting hydraulic rod is provided on one side of the frame, and a stroke seat is provided at the upper end of the lifting hydraulic rod. A rolling hydraulic rod one is provided at the upper end of the stroke seat, and a rolling head one is provided on one side of the rolling hydraulic rod one.
[0006] When using the round steel pre-rolling device of this solution, the heat-treated round steel is conveyed by conveyor rollers and transported inside the frame. Because the side profile of the conveyor rollers is inverted V-shaped, the round steel is guided to the center position during the conveying process, keeping the round steel conveyed straight. After the round steel is conveyed to the designated position, the first fixed hydraulic rod operates, driving the first clamping plate to move relative to each other, clamping the front and rear ends of the round steel. The second fixed hydraulic rod operates, driving the second clamping plate to move longitudinally, pressing the round steel longitudinally. The upper end of the round steel is pressed and fixed. The second rolling hydraulic rod drives the second rolling head to move longitudinally. The instantaneous impact force causes the rolling head two to roll the outer wall of the round steel. When multi-point roll forming at different positions on the same cross section is required, the motor one drives the gear to rotate. Because the gear meshes with the gear ring and the mounting ring is mounted inside the ring seat through the rotating ring, the mounting ring is supported by rotation. The gear ring is pushed by the gear, which drives the mounting ring to rotate. The mounting ring drives the fixed seat to rotate through the mounting seat. The rotation of the fixed seat drives the rolling hydraulic rod two and the rolling head two to adjust the angle. While keeping the round steel stable, the rolling head two positions on the same side cross section of the round steel are rolled.
[0007] The rolling hydraulic rod drives the rolling head to roll the side of the round steel to form the required die. At the same time, the specifications of the round steel change, and the height of the center of the round steel at the top of the conveying roller changes. The lifting hydraulic rod drives the stroke seat to move longitudinally, thereby adjusting the height of the rolling hydraulic rod. The rolling head can effectively correspond to the rolling processing at the center of the side of round steel with different radii.
[0008] During the rolling process, the collection trough collects the oxidized slag from the outer wall of the round steel. During the round steel rolling process, the motor operates to drive the rotating rollers to rotate. The gripping teeth on the outer wall of the rotating rollers form a gripping force on the outer wall of the round steel, pushing the round steel to move laterally, thereby enabling the round steel to adjust its position during the rolling process.
[0009] Preferably, a second connecting plate is provided at the lower end of the second rolling hydraulic rod and the upper end of the second rolling head, and the second connecting plate is installed with bolts. A first connecting plate is provided at the opposite end of the first rolling head and the first rolling hydraulic rod, and the first connecting plates are installed with bolts. The second connecting plate and the first connecting plate are fixed together with bolts, and can be disassembled to replace the first and second rolling heads with different shapes.
[0010] Preferably, the frame is equipped with a collection frame that fits onto the outside of the ring seat, and an opening and closing door is rotatably installed at the front end of the collection frame. Because the heat-treated round steel is soft and slippery, when it is impacted by the rolling head, the oxidized slag on its outer wall is collected by the collection frame. The opening and closing of the collection frame is controlled by the opening and closing door, thereby cleaning the slag.
[0011] Preferably, the conveying roller has an inverted V-shaped side cross-section. When conveying round steel bars, the inverted V-shaped conveying roller guides the steel bars towards the center of the conveying roller.
[0012] Preferably, a bracket is provided at the upper end of the frame, and a fixed hydraulic rod is provided at both the front and rear ends of the bracket. A clamping plate is provided at the telescopic end of each fixed hydraulic rod. The bracket supports the hydraulic rods and clamps them to secure the outer wall of the round steel bars.
[0013] Preferably, a second fixed hydraulic rod is provided inside the upper end of the bracket, and a second clamping plate is provided at the lower end of the second fixed hydraulic rod, with the second clamping plate corresponding to the center of the conveyor roller. When the second fixed hydraulic rod operates, its telescopic end moves longitudinally, driving the second clamping plate to press and fix the upper end of the round steel.
[0014] Preferably, the frame contains a mounting bracket, one end of which is equipped with a second motor. Symmetrically distributed bearings are embedded in both ends of the mounting bracket, and a rotating roller, rotatably mounted to the bearings, is located at the output end of the second motor. The rotating roller receives rotatable support within the mounting bracket via the bearings, and the second motor drives the rotating roller to rotate.
[0015] Preferably, the outer wall of the roller is provided with gripping teeth arranged in a circular array. When the roller rotates inside the mounting frame and contacts the round steel, the gripping teeth increase the contact friction with the outer wall of the round steel.
[0016] Preferably, the lower end of the travel seat is provided with symmetrically distributed guide rods, and one side of the upper end of the frame is provided with a guide sleeve that is slidably sleeved on the outside of the guide rods. When the travel frame moves longitudinally, the guide rods slide inside the guide sleeve to provide sliding guidance for the longitudinal movement of the travel frame.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. In the process of use, the rolling head two rolls the outer wall of the round steel. The outer side of the conveying system is fitted with a ring seat. The rolling head two is driven by the rolling hydraulic rod two. The rolling hydraulic rod two is rotatably installed inside the ring seat through the mounting seat. The position of the rolling hydraulic rod two is adjusted with the ring seat as the center, thereby adjusting the different angles of the rolling head two on the same cross section of the round steel. When the rolling groove is reached, it provides assistance for the rolling of the round steel, which improves the convenience of rolling the round steel at different positions on the same cross section.
