Description

Technical Field

[0001] This utility model relates to the field of cold-formed steel production technology, specifically to an online polishing device for cold-formed steel production. Background Technology

[0002] Cold-formed steel profiles, also known as cold-formed steel profiles or cold-formed profiles, are various complex cross-section profiles made from hot-rolled or cold-rolled strip steel under pressure at room temperature. They are also called thin-walled steel profiles and are a type of lightweight building structural steel. Initially, they were produced by a single bending press. Cold-formed steel profiles have a wide range of applications, generally used in the production of structural components and auxiliary parts in construction, railway vehicles, automobiles, and ships.

[0003] For example, the online polishing device for cold-formed steel roll forming machines, as described in announcement number "CN217750929U," uses the simplest process to complete the online polishing of products, saving a significant amount of manpower and resources, greatly improving production efficiency, and reducing labor intensity. However, this device lacks wear compensation capabilities. As the polishing wheels wear down, it cannot automatically compensate for changes in the polishing wheel diameter, requiring frequent manual adjustments to the polishing wheel position, which affects production efficiency. Furthermore, there is a polishing blind zone between the two polishing wheels, necessitating subsequent adjustments to the profile position for repolishing, resulting in low practicality. Utility Model Content

[0004] The purpose of this invention is to solve the problems of lacking wear compensation performance, failing to automatically compensate for changes in the diameter of the polishing wheel as it wears down, requiring frequent manual adjustments to the position of the polishing wheel, which affects production efficiency, and having a polishing blind zone between the two polishing wheels, requiring subsequent adjustments to the position of the profile for repolishing, resulting in low practicality. Therefore, an online polishing device for cold-bending steel profile units is proposed.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design an online polishing device for cold-formed steel units, including a box and an outer shell. The rear side of the outer wall of the box is fixedly connected to the outer shell. The outer shell has a steel rotating structure inside. The upper part of the box has a polishing wheel supplementary structure. A cylinder is fixedly connected to the inner wall of the box and the outer shell.

[0007] This design utilizes the enclosure and shell to support multiple structures, enhancing stability.

[0008] Preferably, the polishing wheel supplementary structure includes an electric telescopic rod, the output end of which is fixedly connected to a horizontal plate, and the lower ends of the horizontal plate are fixedly connected to two second sliding rods on both sides. The outer walls of the two second sliding rods are slidably connected to the frame, and springs are provided at both ends of the second sliding rods. The two ends of the springs are fixedly connected to the horizontal plate and the frame, respectively, and a first motor is fixedly connected to the front end of the frame.

[0009] This feature allows the polishing wheel to remain in contact with the steel workpiece by a spring-driven frame when it wears down. This compensates for changes in the polishing wheel diameter, eliminating the need for frequent manual adjustments to the wheel's position and thus improving production efficiency.

[0010] Preferably, the bottom of the electric telescopic rod is fixedly connected to the housing, and a polishing wheel is fixedly connected to the end of the output shaft of the first motor. The rotating shaft of the polishing wheel is rotatably connected to the frame through a bearing.

[0011] Preferably, the upper end of the horizontal plate is fixedly connected to the two sides of the first sliding rod, and the outer walls of the two first sliding rods are slidably connected to the box body.

[0012] Preferably, the steel rotating structure includes a second motor, a first bevel gear is fixedly connected to the end of the output shaft of the second motor, the two rotating shafts of the first bevel gears are rotatably connected to the housing through bearings, the outer wall of the first bevel gear is meshed with the second bevel gear, and a rubber roller is fixedly connected to the rotating part of the second bevel gear.

[0013] This feature, through a second motor, ultimately drives the steel parts of the cold-formed steel unit to rotate, enabling circumferential polishing, reducing blind spots in polishing, eliminating the need for secondary polishing, and effectively improving practicality.

[0014] Preferably, the outer wall of the second motor is fixedly connected to the housing via a bracket, and the rotating shaft of the rubber roller is rotatably connected to the housing via a bearing.

[0015] The online polishing device for cold-formed steel mills proposed in this utility model has the following advantages: By supplementing the structure with a polishing wheel, the electric telescopic rod is activated, causing the horizontal plate to move downwards. The horizontal plate then drives the first sliding rod to slide downwards within the housing. The horizontal plate, restricted by the first sliding rod, can only move up and down. This, in turn, drives the second sliding rod, the frame, the first motor, and the polishing wheel downwards, causing the polishing wheel to contact the steel workpiece. Simultaneously, the second sliding rod slides downwards within the frame. When the polishing wheel becomes worn, a spring pushes the frame to maintain the polishing wheel in contact with the steel workpiece. This device can compensate for changes in the polishing wheel diameter, eliminating the need for frequent manual adjustments to the polishing wheel position, thereby improving production efficiency.

[0016] Through the rotating steel structure, the second motor starts and drives the first bevel gear to rotate within the housing via bearings. The first bevel gear drives the second bevel gear to rotate, which in turn drives the rubber rollers to rotate in the same direction within the housing via bearings. Finally, the second motor drives the steel parts of the cold-formed steel unit to rotate, enabling circumferential polishing, reducing polishing blind spots, eliminating the need for secondary polishing, and effectively improving practicality.

[0026] See attached document Figure 2 and 5 The polishing wheel supplementary structure 1 includes an electric telescopic rod 101, which is a Thomson Electrak HD model and has a self-locking function. A horizontal plate 102 is fixedly connected to the output end of the electric telescopic rod 101.

[0030] Working principle:

[0031] Online grinding operation of cold-formed steel section unit:

[0032] When polishing of steel parts of cold-bending steel unit is required, the main body of the device is moved to the rear of the external cold-bending steel unit steel part straightening device, and then the external power supply of the second motor 201 is turned on. The second motor 201 starts and drives the first bevel gear 202 to rotate in the outer shell 6 through the bearing. The first bevel gear 202 drives the second bevel gear 203 to rotate. Then, the two second bevel gears 203 respectively drive the rubber rollers 204 to rotate in the same direction in the box 3 through the bearing. Further, the straightened steel parts enter the cylinder 7 and the outer shell 3 and come into contact with the rubber rollers 204. The rubber rollers 204 drive the steel parts to rotate.

[0033] Then, the external power supply of the electric telescopic rod 101 (the electric telescopic rod 101 is a Thomson ElectrakHD model with self-locking function) is connected. The electric telescopic rod 101 starts and drives the horizontal plate 102 to move downward. The horizontal plate 102 drives the first slide rod 4 to slide downward in the housing 3. The horizontal plate 102 is restricted by the first slide rod 4 to only move up and down. Then, the horizontal plate 102 drives the second slide rod 103, the frame 105, the first motor 106, and the polishing wheel 5 to move downward, so that the polishing wheel 5 abuts against the steel part. At the same time, the second slide rod 103 slides downward in the frame 106, compressing the spring 104. Then, the external power supply of the first motor 106 is connected. The first motor 106 starts and drives the polishing wheel 5 to rotate to polish the steel part. Since the steel part is kept rotating, the steel part can be polished circumferentially.

[0034] As the polishing wheel 5 wears down, the spring 104 pushes the frame 105 down, keeping the polishing wheel 5 in contact with the steel part. This movement automatically compensates for the wear of the polishing wheel 5. The polished steel part is then pushed by the subsequent straightening steel part, allowing for polishing of the remaining parts of the steel part. The polished steel part is then sent out through the front opening of the housing 3. In addition, the front and right sides of the housing 3 are connected to cover plates by bolts and threads, allowing for periodic opening of the cover plates to inspect the internal parts of the housing 3 or to clean the dust using an external vacuum cleaner.

[0035] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
