Description

Technical Field

[0001] This utility model relates to the field of steel plate pretreatment technology, and in particular to a high-precision cold bending forming pretreatment device for steel plates. Background Technology

[0002] High-precision cold bending of steel plates is a processing technology that uses sequentially arranged multi-pass forming rolls to laterally bend metal coils and strips. However, during the forming process, steel plates may rust due to environmental influences. The pressure generated during cold bending can cause defects such as surface depressions due to the rust on the steel plate surface. Therefore, a pre-treatment device is needed to treat the rust on the steel plate surface to improve the quality of cold bending of steel plates.

[0003] In the existing technology, when pre-treating steel plates for rust removal, the steel plates are processed by a pre-treatment device. When processing long steel plates, the sag caused by the weight of the ends causes the steel plates to bend during the process of passing through the device. This bending causes local gaps between the steel plates and the rust removal actuators in the device, resulting in incomplete rust removal and poor surface treatment uniformity. Utility Model Content

[0004] This utility model relates to a high-precision cold bending pretreatment device for steel plates, which solves the problem that when steel plates are processed for rust removal, the steel plates may bend during the process due to the sag caused by their own weight at the ends. This bending results in a local gap between the steel plate and the rust removal actuator inside the device, leading to incomplete rust removal and poor surface treatment uniformity.

[0005] This utility model provides a high-precision cold bending pretreatment device for steel plates, specifically including: a fixed frame, the fixed frame being a rectangular frame structure, and a support bracket installed at the included angle of the bottom edge of the fixed frame; two positioning side plates installed on the inner side of the support bracket; a guide rail installed between the two positioning side plates; a sliding plate slidably installed on the inner side of the guide rail; two guide rods installed on the side of the sliding plate; the guide rods being cylindrical structures, and a movable frame installed through a positioning side plate at the side end of the guide rod; a drive wheel rotatably installed on the inner bottom of the movable frame; a positioning frame installed on the top of the movable frame; the positioning frame being a rectangular frame structure, and a rotating roller rotatably installed on the inner side of the positioning frame.

[0006] Furthermore, the inner side of the fixed frame is equipped with multiple evenly distributed guide rollers, wherein a drive assembly is installed on the side end of the guide rollers; the side end of the fixed frame is provided with a slot, and a cleaning plate is reciprocally slidably installed inside the slot, wherein a wire brush is provided on the cleaning plate; a positioning support plate is installed on the top of the side end of the fixed frame.

[0007] Furthermore, a traction plate is reciprocally slidably installed on the inner side of the positioning support plate; an adjusting threaded rod is rotatably installed on the top of both ends of the traction plate; a cleaning plate two is rotatably installed on the bottom of the adjusting threaded rod, wherein a wire brush is provided at the bottom of the cleaning plate two.

[0008] Furthermore, guide frames are installed on the side ends of both the cleaning plate and the traction plate; a servo motor is installed on the rear side of the support bracket, and a rotating rod is installed on the output end of the servo motor.

[0009] Furthermore, the rotating rod has a cylindrical structure, and two rotating plates are installed on the outer side of the rotating rod; the rotating plates have an elliptical structure, and the rotating plates are rotatably installed on the inner side of the guide frame.

[0010] Furthermore, a collection box is installed on the side end of the support bracket; a drive pump is installed on the side end of the collection box, and a guide pipe is installed on the input end of the drive pump; two collection pipes, one above and one below, are connected to the side of the guide pipe; and a collection cover is installed at the bottom of the side end of the fixed frame.

[0011] Furthermore, the first collection cover is located below the first cleaning plate, and the side of the first collection cover is connected to the lower collection pipe; the second collection cover is installed on the top of the second cleaning plate; the side of the second collection cover is connected to the upper collection pipe.

[0012] This utility model provides a high-precision cold bending pretreatment device for steel plates, which has the following beneficial effects: In use, this utility model lifts a long steel plate by pulling the movable frame outward to move the positioning frame to a suitable position, reducing the sagging problem of the side ends of the long steel plate and greatly improving the levelness of the steel plate when passing through the pretreatment device.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0019] Please refer to Figures 1 to 6 : Example 1: This utility model proposes a high-precision cold bending pretreatment device for steel plates, comprising: a fixed frame 1, which is a rectangular frame structure, and a support bracket 101 is installed at the included angle of the bottom edge of the fixed frame 1; multiple evenly distributed guide rollers 102 are installed on the inner side of the fixed frame 1, wherein a driving component is installed on the side end of the guide rollers 102; a slot is provided on the side end of the fixed frame 1, and a cleaning plate 103 is reciprocally slidably installed inside the slot, wherein a wire brush is provided on the cleaning plate 103; a positioning support plate 104 is installed on the top of the side end of the fixed frame 1; a traction device is reciprocally slidably installed on the inner side of the positioning support plate 104. Plate 105; both ends of the traction plate 105 are rotatably mounted with adjusting threaded rods 106; the bottom of the adjusting threaded rods 106 is rotatably mounted with a second cleaning plate 107, wherein the bottom of the second cleaning plate 107 is provided with a wire brush; guide frames 108 are installed on the side ends of the first cleaning plate 103 and the traction plate 105; a servo motor is installed on the rear side of the support bracket 101, and a rotating rod 109 is installed on the output end of the servo motor; the rotating rod 109 has a cylindrical structure, and two rotating plates 1010 are installed on the outer side of the rotating rod 109; the rotating plates 1010 have an elliptical structure, and the rotating plates 1010 are rotatably mounted on the inner side of the guide frame 108.

[0020] In this embodiment, when performing rust removal pretreatment on the cold-bent steel plate, the position of the second cleaning plate 107 is adjusted according to the thickness of the steel plate. The adjusting threaded rods 106 are rotated sequentially at both ends of the traction plate 105 to adjust the height of the second cleaning plate 107, ensuring a suitable gap between the second cleaning plate 107 and the first cleaning plate 103. The output end of the servo motor on the rear side of the support bracket 101 drives the two rotating plates 1010 on the rotating rod 109 to rotate inside the two guide frames 108. The rotating plates 1010 push the guide frames 108 to reciprocate. The lower guide frame 108... The guide frame 108 drives the first cleaning plate 103 to reciprocate within the slot on the side of the fixed frame 1. The guide frame 108 above drives the traction plate 105 to reciprocate within the positioning support plate 104. The traction plate 105 drives the second cleaning plate 107 to reciprocate via the adjusting threaded rod 106. The guide roller 102 inside the fixed frame 1 drives the steel plate through the space between the second cleaning plate 107 and the first cleaning plate 103. The reciprocating cleaning plates 107 and 103 drive the wire brush to treat the rust on the steel plate. At the same time, the upper and lower sides of the steel plate are cleaned, which greatly improves the efficiency of the rust removal operation.

[0021] In Example 2, based on Example 1, a collection box 2 is installed on the side of the support bracket 101; a drive pump is installed on the side of the collection box 2, and a guide pipe 201 is installed on the input end of the drive pump; two collection pipes 202 are connected to the side of the guide pipe 201; a collection cover 203 is installed at the bottom of the side of the fixed frame 1; the collection cover 203 is also located below the cleaning plate 103, and the side of the collection cover 203 is connected to the collection pipe 202 below; a collection cover 204 is installed on the top of the cleaning plate 107; the side of the collection cover 204 is connected to the upper collection pipe 202. When the cold-bent steel plate is pre-treated for rust removal by connecting the collection pipe 202, the drive pump on the side of the collection box 2 works. The drive pump drives the collection pipe 202 on the guide pipe 201 to absorb airflow. Then the first collection cover 203 collects the rust generated by the first cleaning plate 103, and the second collection cover 204 collects the rust generated by the second cleaning plate 107. Driven by the airflow, the rust enters the interior of the collection box 2 through the collection pipe 202 and the guide pipe 201 for storage, preventing dust from being generated at the rust removal site and ensuring the cleanliness of the operating workshop.

[0022] In Example 3, based on Example 1, two positioning side plates 3 are installed on the inner side of the support bracket 101; a guide rail 301 is installed between the two positioning side plates 3; a sliding plate 302 is slidably installed on the inner side of the guide rail 301; two guide rods 303 are installed on the side of the sliding plate 302; the guide rods 303 are cylindrical, and a movable frame 304 is installed through one of the positioning side plates 3 at the side end of the guide rods 303; a drive wheel 305 is rotatably installed on the inner bottom of the movable frame 304; a positioning frame 306 is installed on the top of the movable frame 304; the positioning frame 306 is a rectangular frame structure, and a rotating roller 307 is rotatably installed on the inner side of the positioning frame 306. When performing rust removal pretreatment on cold-formed steel plates, the position of the movable frame 304 is adjusted according to the length of the steel plate. The movable frame 304 is pulled outward from the other end of the fixed frame 1 to move the guide rod 303. The guide rod 303 passes through a positioning side plate 3 and moves the sliding plate 302 along the guide rail 301, so that the movable frame 304 moves the top positioning frame 306 to a suitable position, so that the top of the positioning frame 306 supports the longer steel plate, reduces the problem of sagging at the side of the steel plate, and further improves the levelness of the steel plate as it passes through the pretreatment device. The rotating roller 307 inside the positioning frame 306 provides friction for the movement of the steel plate.

[0023] The working principle of this embodiment is as follows: Rotating the adjusting threaded rods 106 at both ends of the traction plate 105 moves the second cleaning plate 107, ensuring a suitable gap for steel plate movement between the second cleaning plate 107 and the first cleaning plate 103. The servo motor output drives two rotating plates 1010 on the rotating rod 109 to rotate inside the two guide frames 108. The lower guide frame 108 moves the first cleaning plate 103 back and forth within the slot on the side of the fixed frame 1. The upper guide frame 108 moves the traction plate 105 back and forth via the adjusting threaded rods 106, causing the second cleaning plate 107 to move back and forth. The guide rollers 102 inside the fixed frame 1 move the steel plate between the second cleaning plate 107 and the first cleaning plate 103, causing the steel plate to move back and forth. The cleaning plate 107 and the cleaning plate 103 drive the wire brush to treat the rust on the steel plate. The drive pump on the side of the collection box 2 works, the collection cover 203 collects the rust generated by the cleaning plate 103, and the collection cover 204 collects the rust generated by the cleaning plate 107. The rust is carried by the airflow through the collection pipe 202 and the guide pipe 201 into the collection box 2 for storage. For longer steel plates, the movable frame 304 is pulled outward from the other end of the fixed frame 1 to move the guide rod 303. The guide rod 303 moves the slide plate 302 along the guide rail 301. The movable frame 304 moves the top positioning frame 306 to a suitable position to lift the longer steel plate and improve the level of the steel plate as it passes through the pretreatment device.
