Description

Technical Field

[0001] This utility model relates to the field of processing machinery technology, specifically to an electric rolling machine. Background Technology

[0002] A rolling machine is a key piece of equipment that rolls metal sheets into circular, arc-shaped, or conical workpieces. It is widely used in industries such as boiler, chemical, wind power, and pipe manufacturing for forming and processing rollers, flanges, and rings. Depending on the number of rollers, common rolling machines can be divided into two-axis, three-axis, and four-axis types.

[0003] A search revealed Chinese patent CN209736385U, which discloses an adjustable electric rolling machine, including a fixed frame, an adjusting disc, and rolling rollers. This invention uses a drive motor to move an electric telescopic rod. When the electric telescopic rod extends, it pushes the sliding block outward, moving the fixed seat away from the center of the adjusting disc, increasing the distance between adjacent rolling rollers, thus enabling the processing of large-diameter rollers. When the electric telescopic rod shortens, the sliding block moves inward, moving the fixed seat closer to the center of the adjusting disc, decreasing the distance between adjacent rolling rollers, thus enabling the processing of small-diameter rollers.

[0004] After the workpiece is rolled into a circle, the finished product tightly covers the outside of the upper rolling roller, making it inconvenient to unload. In the existing technology, after the operator completes the processing, it is often necessary to disassemble part or the entire top structure of the electric rolling machine in order to remove the rolled workpiece from the roller. This unloading method is cumbersome, time-consuming and labor-intensive, which not only increases the labor intensity of workers, but also seriously affects the efficiency of continuous production. Based on this, an electric rolling machine is proposed to solve the above problems. Utility Model Content

[0005] Based on the above description, this utility model provides an electric rolling machine to solve the problem that after the workpiece is rolled into a circle, the finished product is tightly wrapped around the outside of the upper rolling roller, making it inconvenient to unload the finished product. In the prior art, after the operator completes the processing, it is often necessary to disassemble part or the entire top structure of the electric rolling machine in order to remove the rolled workpiece from the roller. This unloading method is cumbersome, time-consuming and labor-intensive, which not only increases the labor intensity of workers, but also seriously affects the efficiency of continuous production.

[0006] The technical solution of this utility model to solve the above technical problems is as follows: An electric rolling machine includes a processing platform, a support plate frame, a bearing plate and a second rolling roller. The support plate frame is fixed on the left end of the upper surface of the processing platform, the bearing plate is fixed on the right end of the upper surface of the processing platform, and a first rolling roller is provided at the bottom between the support plate frame and the bearing plate on opposite sides. The support plate frame includes a bottom plate and a top plate, which are rotatably mounted together. The lower surface of the top plate is provided with a disassembly mechanism to facilitate unloading of the workpiece. The top right side of the bearing plate is provided with an ejection mechanism for ejecting the workpiece. The disassembly mechanism includes a U-shaped groove on the lower surface of the top plate, a movable component for limiting the vertical displacement of the second roller, and a rotating component for adjusting the angle of the top plate. One end of the movable component is located in the U-shaped groove and moves linearly up and down within the U-shaped groove.

[0007] Through the above technical solution, by cooperating with the U-shaped groove and the moving parts, the angle of the top plate can be adjusted after the workpiece is rolled into a circle, so that the top plate can be rotated from a vertical state to a horizontal or downward tilted state. This allows the operator to quickly unload the rolled workpiece from the second roller, greatly improving the unloading efficiency.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] Furthermore, the movable component includes a first screw threadedly connected to the top plate, and a pressing block is rotatably connected to the lower surface of the first screw via a bearing; A fixing groove for placing the second roller is provided in the middle of the upper surface of the base plate.

[0010] Through the above technical solution, the setting of the No. 1 screw can adjust the vertical height of the pressing block, ensuring that the workpiece is subjected to uniform force and stable forming during the rolling process.

[0011] Furthermore, the cross-sectional shape of the pressing block is arc-shaped, and the inner diameter of the pressing block is larger than the inner diameter of the fixing groove.

[0012] The above technical solution can limit the second roller by pressing the block, thus preventing it from displacing in the vertical direction.

[0013] Furthermore, the rotating component includes a bidirectional screw that is rotatably connected to the bottom of the inner cavity of the base plate via a bearing. Both ends of the outer surface of the bidirectional screw are threaded with movable plates, and positioning blocks are fixed on the top of the opposite side of the two movable plates.

[0014] Through the above technical solution, the bidirectional screw can enable the two movable plates to move relative to or away from each other on their outer surfaces.

[0015] Furthermore, the two movable plates are symmetrically distributed on the left and right sides of the vertical central axis of the bidirectional screw, and the front and rear sides of the top plate are provided with positioning grooves that are adapted to the size of the positioning block.

[0016] The above technical solution allows the positioning block to move by moving the movable plate, thereby moving the positioning block into the positioning groove and limiting the angle of the top plate.

[0017] Furthermore, a limit block is fixed on the lower surface of the movable plate, and limit grooves adapted to the size of the limit block are provided on both the front and rear sides of the left end of the upper surface of the processing platform.

[0018] Through the above technical solution, the movable plate can drive the limiting block to move within the limiting groove during the movement process, thereby limiting the movement of the movable plate and making it only able to move in a straight line.

[0019] Furthermore, the other end of the second roller is rotatably connected to the support plate via a bearing, and a rotating shaft is rotatably connected to the right side of the support plate via a bearing. The other end of the rotating shaft passes through the support plate and is fixed to the second roller. The upper surface of the processing platform is equipped with a motor at the right end. The output shaft of the motor passes through the bearing plate and is fixed to the No. 1 roller. The output shaft of the motor is connected to the rotating shaft by a belt drive.

[0020] With the above technical solution, the motor can directly drive the first roller to rotate. At the same time, through belt transmission, the power is transmitted to the rotating shaft, thereby driving the second roller to rotate with the first roller, which can perform a rolling operation on the workpiece that enters between the two rollers.

[0021] Furthermore, the ejection mechanism includes a push-pull plate, three moving rods fixed to the left side of the push-pull plate, a fixed plate fixed to the left side of the three moving rods, and a pusher plate fixed to the lower surface of the fixed plate. The right side of the bearing plate is provided with three through holes for the moving rods to move horizontally. The lower surface of the pusher plate is provided with an arc-shaped groove that matches the outer diameter of the second roller.

[0022] With the above technical solution, after the workpiece is rolled into a circle, the ejection mechanism can conveniently and precisely adjust the horizontal position of the pusher plate. By driving the pusher plate to move smoothly to the left along the outer surface of the second roll, the rolled workpiece is pushed out of the second roll a certain distance, which facilitates the picking and placing of the workpiece and significantly improves production efficiency and operational safety.

[0023] Furthermore, the three movable rods are arranged in a triangle on the left side of the push-pull plate.

[0024] The above technical solution utilizes the stability principle of triangles to provide a stable, anti-torsion, and uniformly stressed linear motion guide for the push-pull plate.

[0025] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: 1. Through the cooperation between the U-shaped groove and the moving parts, the angle of the top plate can be adjusted after the workpiece is rolled into a circle, so that the top plate can be rotated from a vertical state to a horizontal or downward tilted state. This allows the operator to quickly unload the rolled workpiece from the No. 2 roller, greatly improving the unloading efficiency. 2. After the workpiece is rolled into a circle, the ejection mechanism can easily and precisely adjust the horizontal position of the pusher plate. By driving the pusher plate to move smoothly to the left along the outer surface of the second roll, the rolled workpiece is pushed out of the second roll a certain distance, which facilitates the handling of the workpiece and significantly improves production efficiency and operational safety.

[0028] To facilitate understanding of this application, a more complete description will be provided below with reference to the accompanying drawings, which illustrate embodiments of the present application. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this application will be thorough and complete.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0030] Example: Reference Figure 1 An electric rolling machine includes a processing platform 1, a support plate frame 2, a bearing plate 3, and a second rolling roller 7. The support plate frame 2 is fixed to the left end of the upper surface of the processing platform 1, and the bearing plate 3 is fixed to the right end of the upper surface of the processing platform 1. A first rolling roller 6 is provided at the bottom between the opposite sides of the support plate frame 2 and the bearing plate 3. The support plate frame 2 includes a bottom plate 21 and a top plate 22, which are rotatably mounted. The lower surface of the top plate 22 is provided with a disassembly mechanism 4 for unloading the processed workpiece. The top right side of the bearing plate 3 is provided with an ejection mechanism 5 for ejecting the processed workpiece.

[0031] refer to Figure 2 The disassembly mechanism 4 includes a U-shaped groove 41 formed on the lower surface of the top plate 22, a movable part for limiting the vertical displacement of the second roller 7, and a rotating part for adjusting the angle of the top plate 22. One end of the movable part is located in the U-shaped groove 41 and moves linearly up and down in the U-shaped groove 41.

[0032] In this embodiment, the movable part includes a first screw 42 that is threadedly connected to the top plate 22, and a pressing block 43 is rotatably connected to the lower surface of the first screw 42 via a bearing; a fixing groove for placing the second roller 7 is provided in the middle of the upper surface of the bottom plate 21.

[0033] The pressing block 43 has an arc-shaped cross-section and its inner diameter is larger than that of the fixing groove. The pressing block 43 can be used to limit the vertical displacement of the left end of the second roller 7.

[0034] In this embodiment, the rotating component includes a bidirectional screw 44 rotatably connected to the bottom of the inner cavity of the base plate 21 via a bearing. Both the left and right ends of the outer surface of the bidirectional screw 44 are threaded with movable plates 45, and positioning blocks 46 are fixed on the top of the opposite side of the two movable plates 45.

[0035] Two movable plates 45 are symmetrically distributed on the left and right sides of the vertical central axis of the bidirectional screw 44. The top plate 22 has positioning grooves 47 on both the front and rear sides that are adapted to the size of the positioning block 46. The top plate 22 and the bottom plate 21 can be fixed by the positioning block 46 entering the positioning groove 47.

[0036] In addition, a limit block is fixed on the lower surface of the movable plate 45, and limit grooves that are adapted to the size of the limit block are provided on both the front and rear sides of the left end of the upper surface of the processing platform 1. The limit block and the limit groove can limit the movement of the movable plate 45 when it moves, so that it can only move in a straight line.

[0037] It should be noted that a motor is fixed to the left end of the upper surface of the machining platform 1. The output shaft of the motor is fixed to the bidirectional screw 44, and the rotation of the bidirectional screw 44 can be driven by the rotation of the motor output shaft. After the workpiece is rolled into a circle, the pressing block 43 can be moved upward by rotating the first screw 42. Then, the motor is started, and the output shaft of the motor rotates, driving the bidirectional screw 44 to rotate. The rotation of the bidirectional screw 44 causes the two movable plates 45 threaded on its surface to move in opposite directions. At this time, the movement of the movable plates 45 drives the limiting block to move in the limiting groove, which allows the movable plates 45 to move linearly. The opposite movement of the two movable plates 45 drives the two positioning blocks 46 to move in opposite directions, thereby allowing the positioning blocks 46 to disengage from the positioning groove 47, releasing the limiting of the top plate 22. Then, the top plate 22 can be moved away from the vertical central axis of the processing platform 1.

[0038] refer to Figure 4 The other end of the second roller 7 is rotatably connected to the support plate 3 via a bearing. The right side of the support plate 3 is rotatably connected to a rotating shaft 81 via a bearing. The other end of the rotating shaft 81 passes through the support plate 3 and is fixed to the second roller 7.

[0039] Among them, a motor 82 is fixed at the right end of the upper surface of the processing platform 1. The output shaft of the motor 82 passes through the bearing plate 3 and is fixed to the first roller 6. The output shaft of the motor 82 is connected to the rotating shaft 81 by belt drive.

[0040] The motor 82 can be started, and the output shaft of the motor 82 rotates, driving the first roller 6 to rotate. Through the transmission of the outer belt of the motor 82, the power is transmitted to the rotating shaft 81. The rotation of the rotating shaft 81 causes the second roller 7 to rotate, thus allowing the second roller 7 and the first roller 6 to rotate. The workpiece can be placed between the two rollers for rolling.

[0041] refer to Figure 3 The ejection mechanism 5 includes a push-pull plate 51, three moving rods 52 fixed to the left side of the push-pull plate 51, a fixed plate 53 fixed to the left side of the three moving rods 52, and a push plate 54 fixed to the lower surface of the fixed plate 53. The right side of the bearing plate 3 is provided with three through holes 55 for the moving rods 52 to move horizontally. The lower surface of the push plate 54 is provided with an arc-shaped groove that matches the outer diameter of the second roller 7.

[0042] Among them, the three moving rods 52 are arranged in a triangle on the left side of the push-pull plate 51, and the size of the push plate 54 can be selected according to actual needs.

[0043] In use, the push-pull plate 51 can be pushed, and the movement of the push-pull plate 51 causes the three moving rods 52 and the fixed plate 53 to move. At this time, the three moving rods 52 move in the three through holes 55 respectively, and the movement of the fixed plate 53 causes the push plate 54 to slide on the outside of the second roller 7. Then the push plate 54 can push the rolled and formed workpiece to the left a certain distance, making it easier for the workers to pull out the rolled and formed workpiece.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
