[0002] Simply put, a cleaning machine is a machine that cleans the surface of a workpiece. A roller-type steel shot cleaning machine can clean sections, steel plates, and reasonably sized structural components in a single pass. This machine can remove weldability and improve fatigue resistance, ultimately enhancing both surface and internal quality.

[0003] In the prior art, sheet metal parts are products processed by sheet metal technology. However, due to the thin thickness of the sheet metal parts, the surface of the sheet metal parts will be deformed by force after processing. When the projectiles of the cleaning machine impact the surface of the sheet metal parts, the force will be unloaded by the deformed surface, affecting the impact of the projectiles, thereby affecting the surface cleaning effect of the sheet metal parts.

[0011] Furthermore, the minor diameter of the guide surface is larger than the diameter of the main pressure roller, so that a plane for limiting the sheet metal part remains on the inner side wall of the limiting portion.

[0012] Furthermore, a motor is fixedly connected to the outer side wall of the support frame, and an output shaft of the motor is fixedly connected to the auxiliary pressure roller.

DETAILED DESCRIPTION

[0025] The present invention will be described in further detail below with reference to the accompanying drawings.

[0026] Example:

[0027] Reference Figure 1 - Figure 6 The utility model discloses a sheet metal flattening device for a cleaning machine, comprising a cleaning machine body 1, a roller conveyor 2 for transporting sheet metal parts is provided on one side of the cleaning machine body 1, a support frame 3 is provided at the input end of the roller conveyor 2, a hydraulic press 4 is fixedly connected to the top of the support frame 3, an output shaft of the hydraulic press 4 passes through the support frame 3 and is fixedly connected to a slide 5, a main pressing roller 7 is connected to the bottom of the slide 5 through an elastic member 6, and an auxiliary pressing roller 8 is rotatably connected to the bottom of the main pressing roller 7 in the support frame 3;

[0028] The outer side wall of the main pressure roller 7 is protruded at both ends of the auxiliary pressure roller 8 to form a limiting portion 9, and the outer edge of the inner side wall of the limiting portion 9 is provided with a guide surface 10 for guiding the sheet metal part.

[0029] In this embodiment, after processing, the surface of the sheet metal will be deformed by external force, resulting in the projectiles thrown by the cleaning machine being unloaded by the surface inclination angle of the sheet metal when impacting the sheet metal, affecting the cleaning effect of the projectiles on the sheet metal.

[0030] Therefore, observe Figure 1 It can be found that a roller conveyor 2 for conveying sheet metal parts is provided on one side of the cleaning machine body 1, and a support frame 3 is installed at the input end of the roller conveyor 2. Figure 2 It can be found that a hydraulic press 4 is installed on the top of the support frame 3, and then a slide 5 connected to the output shaft of the hydraulic press 4 is provided in the support frame 3. The slide 5 slides up and down to bring the main pressure roller 7 at the bottom of the slide 5 close to the auxiliary pressure roller 8, so that the main pressure roller 7 and the auxiliary pressure roller 8 squeeze the sheet metal parts to flatten them, so that the surface of the sheet metal parts remains flat when they enter the cleaning machine body 1, so that the cleaning machine body 1 can better clean the sheet metal parts, which can effectively improve the quality of the sheet metal parts.

[0031] Since the main pressing roller 7 and the auxiliary pressing roller 8 apply pressure to the sheet metal to flatten it, when the sheet metal is located at the edge of the main pressing roller 7 and the auxiliary pressing roller 8, the edge of the sheet metal will extend out of the squeezing area of ​​the main pressing roller 7 and the auxiliary pressing roller 8, causing indentations on the surface of the sheet metal, which will affect the quality of the sheet metal and cause it to be scrapped. Figure 6 It can be found that the outer wall of the main pressure roller 7 is protruded at both ends of the auxiliary pressure roller 8 to form a limiting portion 9, and at the same time, a guide surface 10 is processed at the outer edge of the inner wall of the limiting portion 9, so that when the inclined sheet metal enters the extrusion area of ​​the main pressure roller 7, it will first contact the guide surface 10, and then enter the extrusion area of ​​the main pressure roller 7 under the traction of the guide surface 10, which can effectively avoid indentations on the edges of the sheet metal and ensure the flattening effect of the sheet metal.

[0032] In a further preferred embodiment of the present invention, Figure 4 As shown, the main pressure roller 7 and the auxiliary pressure roller 8 are both arranged in plurality at intervals, and the plurality of main pressure rollers 7 and the auxiliary pressure rollers 8 are staggered;

[0033] The main pressure rollers 7 located at the left and right edges of the support frame 3 are arranged directly above the corresponding auxiliary pressure rollers 8;

[0034] The top of the roller conveyor 2 is provided with an avoidance groove 11 for avoiding the auxiliary pressure roller 8 , and the outer edge top surface of the auxiliary pressure roller 8 and the outer edge top surface of the conveying roller of the roller conveyor 2 are in the same horizontal plane.

[0035] In this embodiment, since the support frame 3 is installed at the input end of the roller conveyor 2, and an auxiliary pressure roller 8 for supporting the sheet metal is provided in the support frame 3, and in order to avoid the sheet metal from being blocked during the transportation of the roller conveyor 2, an avoidance groove 11 for avoiding the auxiliary pressure roller 8 is opened on the roller conveyor 2, so that the top surface of the outer wall of the auxiliary pressure roller 8 and the top surface of the outer wall of the conveying roller of the roller conveyor 2 are maintained at the same horizontal plane, which can make the transportation of the sheet metal more stable.

[0036] observe Figure 4The deformation of the sheet metal plate is caused by uneven surface force. Therefore, it can be found that there are multiple main pressure rollers 7 and auxiliary pressure rollers 8, and the multiple main pressure rollers 7 and auxiliary pressure rollers 8 are staggered. When the sheet metal enters the extrusion area of ​​the main pressure roller 7 and the auxiliary pressure roller 8, it will be subjected to pressure at different points by the multiple staggered main pressure rollers 7 and auxiliary pressure rollers 8, so that the sheet metal plate is subjected to multiple alternating bending in opposite directions, so that its internal stress exceeds the yield strength of the material, so that the steel plate is flattened, which can effectively ensure the flattening effect of the sheet metal.

[0037] However, since the sheet metal is deformed by the main pressure roller 7 or the auxiliary pressure roller 8, its extension forward direction is the same as the outer edge tangent direction of the main pressure roller 7 or the auxiliary pressure roller 8, the sheet metal will be tilted when it comes out of the support frame 3, and lose support when it is completely out of the support frame 3, and finally hit the roller 2. Therefore, in order to avoid damage to the sheet metal when it falls, and also to avoid damage to the roller 2, the main pressure rollers 7 located at the left and right edges of the support frame 3 are arranged directly above the corresponding auxiliary pressure rollers 8. The main pressure rollers 7 and the auxiliary pressure rollers 8 can be used to squeeze the sheet metal to make it finally squeezed out horizontally, reducing damage to the sheet metal and the roller 2, and further ensuring the smooth movement of the sheet metal.

[0038] In a further preferred embodiment of the present invention, Figure 6 As shown, the minor diameter of the guide surface 10 is larger than the diameter of the main pressure roller 7, so that the inner side wall of the limiting portion 9 retains a plane for limiting the sheet metal part.

[0039] In this embodiment, by providing a guide surface 10 on the limiting portion 9, the inclined sheet metal part can be pulled by the guide surface 10 when moving and move to the extrusion area of ​​the main pressure roller 7 and the auxiliary pressure roller 8, so that the flattening effect of the sheet metal part is better. When the guide surface 10 is set too large, resulting in the inner side wall of the limiting portion 9 having no side wall for providing support for the sheet metal part, the edge of the sheet metal part will be squeezed by the guide surface 10 at the same time when it is extruded, causing the edge surface of the sheet metal part to deform.

[0040] Therefore, observe Figure 6 It can be found that by making the minor diameter of the guide surface 10 larger than the diameter of the main pressure roller 7, a plane for limiting the sheet metal part can be retained on the inner wall of the limiting portion 9, thereby preventing the edge of the sheet metal part from being squeezed and deformed by the guide surface 10 when under pressure, further ensuring the flattening effect of the sheet metal part.

[0041] In a further preferred embodiment of the present invention, Figure 3 As shown, the outer side wall of the support frame 3 is fixedly connected to a motor 12 , and the output shaft of the motor 12 is fixedly connected to the auxiliary pressure roller 8 .

[0042] In this embodiment, when the main pressure roller 7 and the auxiliary pressure roller 8 squeeze the sheet metal part, the friction force of the pressed surface of the sheet metal part is much greater than the friction force when it contacts the roller 2, which will cause the sheet metal part to be unable to be transported normally, affecting the flattening efficiency of the sheet metal part.

[0043] Therefore, observe Figure 3 It can be found that a motor 12 is fixedly connected to the outer wall of the support frame 3. The motor 12 is used to drive the auxiliary pressure roller 8 to rotate actively, and the auxiliary pressure roller 8 is used to push the sheet metal forward, which can effectively ensure the flattening efficiency of the sheet metal.

[0044] In a further preferred embodiment of the present invention, Figure 2 、 Figure 4 and Figure 5 As shown, the elastic member 6 includes a slider 61 and a compression spring 62. The bottom of the slide 5 is concave to form a mounting groove 13 for mounting the main pressure roller 7. The inner side wall of the mounting groove 13 is provided with a slide groove 14. The slide groove 14 is slidably connected with a slider 61 that is rotatably connected to the main pressure roller 7. A compression spring 62 is arranged between the top of the slider 61 and the slide groove 14.

[0045] In this embodiment, a mounting groove 13 is provided at the bottom of the slide 5 to mount the main pressing roller 7. In order to allow the sheet metal to be extruded horizontally after being flattened, the main pressing rollers 7 at the left and right edges of the support frame 3 are arranged directly above the corresponding auxiliary pressing rollers 8. As a result, when the main pressing rollers 7 at these edges extrude the sheet metal, they will be supported by the auxiliary pressing rollers 8, affecting the downward pressure of the main pressing rollers 7, thereby affecting the extrusion of the sheet metal by the remaining main pressing rollers 7, resulting in a poor flattening effect of the sheet metal. Therefore, Figure 2 and Figure 5 It can be found that a slide groove 14 is opened on the inner wall of the installation groove 13, and a slider 61 is slidably set in the slide groove 14, and a compression spring 62 is provided between the top of the slider 61 and the slide groove 14. The deformation of the high-pressure compression spring 62 can be used to automatically adjust the position of the main pressure roller 7 to ensure that sufficient pressure is applied to the sheet metal.

[0046] The embodiments of this specific implementation method are all preferred embodiments of the present utility model, and are not intended to limit the scope of protection of the present utility model. Therefore, any equivalent changes made based on the structure, shape, and principle of the present utility model should be included in the scope of protection of the present utility model.
