Abstract
Description
Technical Field
[0001] This utility model relates to the field of sheet metal straightening technology, specifically a sheet metal straightening machine with lubrication function. Background Technology
[0002] When the sheet material enters the roller straightening machine, it is subjected to pressure from the staggered working rollers. Under this pressure, the sheet material undergoes elasto-plastic deformation. Due to the original curved state of the sheet material, the fiber lengths are different in different parts. As the sheet material passes through the working rollers, the outer fibers are stretched, while the inner fibers are compressed. As the sheet material moves between the rollers, the fibers continuously undergo stretching and compression processes, and the originally uneven fibers gradually tend to be of uniform length, thereby gradually increasing the radius of curvature of the sheet material and transforming it into a flat state.
[0003] Existing patent CN207494214U describes a rolling mill lubrication control system, belonging to the field of rolling technology. The rolling mill lubrication control system includes: at least three liquid supply devices, each containing an emulsion of a first concentration, a second concentration, and a third concentration; at least three conveying devices, with their first ends connected to the three liquid supply devices and their second ends connected to the rolling mill nozzles; at least three first pumps disposed within the at least three conveying devices; a control device connected to the at least three first pumps and the nozzles; and an input device connected to the control device. This utility model's rolling mill lubrication control system can select different concentrations of liquid according to the steel grade to meet the lubrication needs of rolling different materials, achieving efficient rolling between different materials. However, during the process of the pressure rollers extruding the sheet metal, impurities from the sheet surface adhere to the rollers. When the rollers rotate and come into contact with the sheet metal again, it affects the sheet metal's forming. Therefore, a new device for cleaning the pressure rollers with lubricating fluid is needed. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a sheet metal straightening machine with lubrication function, which solves the problem mentioned in the background technology of impurities adhering to the pressure rollers affecting the sheet metal forming.
[0005] Technical solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a plate straightening machine with lubrication function, comprising a pair of straightening pressure rollers, with support frames on both sides of the pressure rollers, and multiple sets of spray pipes at the feed end of the pressure rollers. The spray pipes are divided into two groups, one group of which is distributed along the pressure rollers with the spray holes pointing towards the axis of the pressure rollers, and the other group of which is located on the upper and lower sides of the plate with the spray holes pointing towards the feed direction of the plate. The spray pipes are interconnected and connected at the inlet end with a pump running through them.
[0007] Furthermore, the spray pipe is provided with a fixing frame at both ends for support, and the fixing frame is fixedly connected to the support frame respectively. The outer surface of the spray pipe away from the spray hole is wrapped with a semi-ring, and adjacent semi-rings are fixedly connected by a connecting frame.
[0008] Furthermore, the spray pipe is fixedly connected to the fixing frame.
[0009] Furthermore, the fixing frame is fixedly installed with jet pipes on the upper and lower sides of the plate. The nozzles of the jet pipes are inclined to both sides of the vertical center line of the jet pipes. The two jet pipes are connected to each other and connected at the inlet end with an air source.
[0010] Furthermore, the spray pipe is slidably connected to the fixed frame, and the end face of the spray pipe is provided with a limit hole. A limit shaft that is slidably connected in the limit hole is fixedly installed on the surface of the fixed frame. A telescopic air column is fixedly installed on the surface of the fixed frame. The free end of the telescopic air column is fixedly connected to the spray pipe. An exhaust hole is opened at the fixed end of the telescopic air column. The fixed end of the telescopic air column is connected to and connected to an air source. The telescopic air columns on both sides are controlled to extend and retract alternately by a control valve.
[0011] Furthermore, the telescopic range of the telescopic air column is greater than the distance between adjacent spray holes of the spray pipe, and the telescopic range of the telescopic air column is less than twice the distance between adjacent spray holes of the spray pipe.
[0012] The beneficial effects of this utility model are as follows:
[0013] 1. This lubrication-function plate straightening machine uses two spray pipes to spray lubricant onto the plate surface for lubrication, and another spray pipe sprays the pressure rollers to blow off impurities from the roller surface. At the same time, an air jet pipe blows air from the top of the plate to both sides, which can blow excess lubricant and fallen impurities into the collection tank, ultimately achieving cleaning of the pressure rollers and lubrication of the plate.
[0014] 2. This lubricating plate straightening machine sprays lubricating liquid through the spray pipe, while the telescopic air columns on both sides extend alternately under the control of the air intake and exhaust holes controlled by the control valve. This allows the spray pipe to move laterally back and forth, avoiding continuous impact of the spray pipe on the same position of the pressure roller. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] Example 1, see reference Figures 1-5 A sheet metal straightening machine with lubrication function includes a pair of straightening machine pressure rollers 1. Support frames 2 are provided on both sides of the pressure rollers 1. A collection pool is provided below the pressure rollers 1 to collect excess lubricant. Multiple sets of spray pipes 4 are provided at the feed end of the pressure rollers 1. The spray pipes 4 are divided into two groups. One group of spray pipes 4 is distributed along the pressure rollers 1, and the spray holes of the spray pipes 4 point to the axis of the pressure rollers 1. The other group of spray pipes 4 is located on the upper and lower sides of the sheet metal, and the spray holes of the spray pipes 4 point to the feed direction of the sheet metal. The spray pipes 4 are interconnected and connected at the inlet end and a pump 5 passes through them.
[0023] Specifically, the spray pipe 4 has fixed brackets 6 at both ends for support, and the spray pipe 4 is fixedly connected to the fixed brackets 6. This arrangement ensures that the spray pipe 4 can be height-adjusted along with the pressure roller 1. At the same time, the connecting guide tubes between the spray pipes 4 have a margin to facilitate movement along with the spray pipe 4. The fixed brackets 6 are fixedly connected to the support frame 2 respectively. The outer surface of the spray pipe 4 is wrapped with a semi-ring 7 on the side away from the spray hole. Adjacent semi-rings 7 are fixedly connected by a connecting bracket 8. This arrangement allows the spray pipe 4 to spray lubricating fluid onto the pressure roller 1 and the pressed sheet material at the same time, thereby ensuring that the sheet material receives sufficient lubrication during extrusion and cleaning the pressure roller 1.
[0024] Based on the previous embodiment, the fixing frame 6 is fixedly installed with air jet pipes 9 on the upper and lower sides of the plate. The nozzles of the air jet pipes 9 are inclined to both sides of the vertical center line of the air jet pipes 9. The two air jet pipes 9 are connected to each other and connected at the inlet end and have an air source 10 through them. With this arrangement, excess lubricant on the surface of the plate can be blown away, and impurities that fall off the pressure roller 1 can be blown away to both sides to prevent impurities from adhering to the plate.
[0025] Based on the previous embodiment, the spray pipe 4 and the fixed frame 6 are slidably connected. The end face of the spray pipe 4 is provided with a limit hole 11. The surface of the fixed frame 6 is fixedly installed with a limit shaft 12 that is slidably connected in the limit hole 11. The surface of the fixed frame 6 is fixedly installed with a telescopic air column 13. The free end of the telescopic air column 13 is fixedly connected to the spray pipe 4. The fixed end of the telescopic air column 13 is provided with an exhaust hole 14. The fixed end of the telescopic air column 13 is connected to and communicates with the air source 10. The telescopic air columns 13 on both sides are controlled to extend and retract alternately by the control valve 15. With this setting, the spray pipe 4 can move back and forth under the drive of the telescopic air column 13, thereby avoiding the direct spraying of lubricating liquid to one position, which would cause the pressure roller 1 to be impacted and grooved.
[0026] Specifically, the telescopic air column 13 has a telescopic range greater than the distance between adjacent spray holes of the spray pipe 4, and the telescopic range of the air column 13 is less than twice the distance between adjacent spray holes of the spray pipe 4. This setting can limit the movement range of the spray pipe 4.
[0027] During use, the sheet material passes through two pressure rollers 1 under the action of the traction mechanism. During the passage, two spray pipes 4 spray lubricant onto the surface of the sheet material for lubrication, while the other spray pipe 4 sprays the pressure rollers 1 to blow off impurities on the surface of the pressure rollers 1. At the same time, an air jet pipe 9 blows air from the top of the sheet material to both sides, thereby blowing excess lubricant and fallen impurities into the collection tank, ultimately achieving the cleaning of the pressure rollers 1 and the lubrication of the sheet material.
[0028] While the spray pipe 4 sprays out lubricating fluid, the telescopic air columns 13 on both sides extend alternately under the control of the air intake and exhaust holes 14 controlled by the control valve 15, so that the spray pipe 4 can move laterally back and forth, avoiding the spray pipe 4 from continuously impacting the same position of the pressure roller 1.
[0029] It should be noted that in this document, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.
[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
