Description

Technical Field

[0001] This utility model relates to the field of sheet metal flattening, specifically a sheet metal flattening device. Background Technology

[0002] Sheet metal flattening devices are mainly used for flattening sheet metal parts before processing to ensure the accuracy of the sheet metal parts during processing. Existing sheet metal flattening devices have a fixed outlet height. When there is a large height difference between the outlet of the sheet metal flattening device and the sheet metal processing equipment, the sheet metal parts will be suspended for a distance during the process of being transported to the processing equipment. At this time, because the sheet metal parts are thin, the suspended section of the sheet metal parts is prone to vibration during the flattening process. Moreover, the longer the suspended length of the sheet metal parts, the more likely it is to vibrate, thus affecting the subsequent processing accuracy of the sheet metal parts. Utility Model Content

[0003] The purpose of this utility model is to provide a sheet metal flattening device to overcome the above-mentioned defects in the prior art.

[0004] According to the present invention, a sheet metal flattening device includes a frame and a flattening mechanism. The frame includes a base plate and two side plates vertically fixed to the base plate. The flattening mechanism is rotatably connected between the two side plates. A fixing plate is fixed between the two side plates. A vertically penetrating lifting screw is threaded into the fixing plate. A rotating handle located on the upper side of the fixing plate is fixed on the outer periphery of the lifting screw. The upper end of the lifting screw abuts against the flattening mechanism and is away from the rotation center of the flattening mechanism. The tilt of the flattening mechanism can be adjusted by rotating the lifting screw.

[0005] Furthermore, the flattening mechanism includes a housing, which is hollow inside and open at both ends and the top. Two pairs of pressure rollers are installed inside the housing, located at the front and rear ends respectively. Each pair of pressure rollers is distributed on the upper and lower sides. Several equidistant conveying rollers are arranged between the pressure rollers on the front and rear sides. A power module is fixed on one side of the housing, and the conveying rollers and pressure rollers on the lower side are poweredly connected to the power module.

[0006] Furthermore, the lower pressure roller and the conveyor roller are rotatably connected to the two side walls of the housing at both ends. The upper pressure roller is provided with a pressure roller frame, and the left and right ends of the pressure roller frame are fixed with downwardly extending flat plates. The left and right ends of the upper pressure roller are respectively rotatably connected to the flat plates at both ends of the pressure roller frame. The flat plates at both ends of the pressure roller frame are slidably connected to the two side walls of the housing. A cover plate is fixed on the upper end face of the housing. The cover plate has round holes corresponding to the two ends of the pressure roller frame. Two pressure plates are provided on the upper end face of the cover plate. Springs that pass through round holes are fixed between the two ends of the pressure plates and the two ends of the pressure roller frame. Two first adjusting screws that pass through the two pressure plates are fixed on the upper end face of the cover plate. Threaded handles that abut against the pressure plates are threaded on the first adjusting screws.

[0007] Furthermore, both sides of the housing are provided with conveyor roller frames that slide vertically. The two ends of the conveyor rollers are rotatably connected to the conveyor roller frames on the left and right sides. A second adjusting screw that passes through the cover plate is rotatably connected to the conveyor roller frame. The second adjusting screw is threadedly connected to the cover plate.

[0008] Furthermore, two feed roller frames are fixed at the rear end of the housing, and a feed support roller is rotatably connected between the two feed roller frames. Two discharge support rollers are fixed at the front end of the housing, and a discharge roller frame is rotatably connected between the two discharge support rollers.

[0009] Furthermore, two connecting plates are fixed to the lower end face of the housing. The two connecting plates abut against the inner sides of the two side plates respectively. A central shaft located below the feed support roller is fixed between the two side plates. The central shaft passes through the two connecting plates and is rotatably connected to them. A left-right through-limiting groove is opened on both connecting plates. The limiting groove is located below the pressure roller. The limiting groove is arc-shaped and its center coincides with the axis of the central shaft. A limiting rod passing through the corresponding limiting groove is fixed to the inner side of the side plate.

[0010] Furthermore, the axis of the lifting screw is aligned with the line connecting the two limit rods.

[0011] Furthermore, a support plate is provided on the upper side of the fixed plate, and two symmetrically arranged frame plates are fixed between the support plate and the fixed plate. The upper half of the lifting screw is a smooth rod, and the lower half is threaded. The rotating handle is fixed to the smooth rod part of the lifting screw, and the smooth rod part of the lifting screw passes through the support plate.

[0012] The beneficial effects of this utility model are as follows: After the sheet metal part is flattened by the flattening device, it is then sent out from the front end of the flattening device. By rotating the handle, the lifting screw is rotated, which in turn causes the lifting screw to rise and fall in the vertical direction. The front end of the flattening device rises and falls with the upper end of the lifting screw. Thus, the height of the sheet metal part's discharge position after flattening can be adjusted according to the height of the sheet metal processing equipment, thereby reducing the height difference between the discharge port of the sheet metal flattening device and the sheet metal processing equipment, shortening the length of the sheet metal part suspended in the air, reducing the vibration of the sheet metal part, and improving the processing accuracy of the sheet metal part.

It should be understood that the following text is merely used to describe one or more specific implementations of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up and down and left and right are not limited to their strict geometric definitions, but include tolerances for reasonable and inconsistent machining or human errors. The specific features of this sheet metal flattening device are described in detail below:

[0021] One embodiment of this utility model:

[0022] Reference Figures 1-4 This utility model provides a sheet metal flattening device, including a frame and a flattening mechanism. The frame includes a base plate 10 and two side plates 11 vertically fixed on the base plate 10. The flattening mechanism is rotatably connected between the two side plates 11. A fixing plate 12 is fixed between the two side plates 11. A vertically penetrating lifting screw 21 is threaded into the fixing plate 12. A rotating handle 22 located on the upper side of the fixing plate 12 is fixed on the outer periphery of the lifting screw 21. The upper end of the lifting screw 21 abuts against the flattening mechanism and is away from the rotation center of the flattening mechanism. The tilt of the flattening mechanism can be adjusted by rotating the lifting screw 21.

[0023] Reference Figure 4The flattening mechanism includes a housing 30, which is hollow inside and open at both ends and the top. Inside the housing 30, there are two pairs of pressure rollers 53 located at the front and rear ends of the housing 30, respectively. Each pair of pressure rollers 53 is distributed on the upper and lower sides. Between the pressure rollers 53 on the front and rear sides, there are several equidistant conveying rollers 52. A power module 34 is fixed on one side of the housing 30. The lower conveying rollers 52 and the lower pressure rollers 53 are poweredly connected to the power module 34. The power module 34 includes a motor, a belt, and pulleys. The lower conveying rollers 52 and the pressure rollers 53 are fixed with pulleys at the ends near the power module 34. The pulleys are connected by a belt. One of the conveying rollers 52 is connected to the output shaft of the motor. The power transmission between the belt and the pulleys enables the lower conveying rollers 52 and the pressure rollers 53 to rotate synchronously.

[0024] Reference Figures 1-4 The lower pressure roller 53 and the conveyor roller 52 are rotatably connected to the two side walls of the housing 30 at both ends. A pressure roller frame 50 is provided on the upper side of the upper pressure roller 53. The left and right ends of the pressure roller frame 50 are fixed with downwardly extending flat plates. The left and right ends of the upper pressure roller 53 are respectively rotatably connected to the flat plates at both ends of the pressure roller frame 50. The flat plates at both ends of the pressure roller frame 50 are slidably connected to the two side walls of the housing 30. A cover plate 40 is fixed on the upper end face of the housing 30. The cover plate 40 has openings corresponding to the two ends of the pressure roller frame 50. The cover plate 40 has a round hole, and two pressure plates 44 are provided on the upper side. Springs 45 are fixed between the two ends of the pressure plates 44 and the two ends of the pressure roller frame 50 through the round hole. Two first adjusting screws 41 are fixed on the upper end face of the cover plate 40, which respectively pass through the two pressure plates 44. The first adjusting screws 41 are threadedly connected to the first adjusting screws 41 and have threaded handles 42 that abut against the pressure plates 44. By rotating the threaded handles 42, the height of the pressure plates 44 can be adjusted, thereby adjusting the distance between the pressure plates 44 and the pressure roller frame 50, thereby adjusting the compression of the springs 45. This allows the pressure of the pressure roller 53 to be adjusted according to the thickness of the sheet metal part. When flattening a thicker sheet metal part, the pressure of the pressure roller 53 is increased, and when flattening a thinner sheet metal part, the pressure of the pressure roller 53 is decreased, so as to avoid excessive pressure of the pressure roller 53 when flattening a thinner sheet metal part, which would cause the sheet metal part to stretch and deform.

[0025] Reference Figure 1 , Figure 4 The left and right side walls of the housing 30 are provided with conveyor roller frames 51 that slide vertically. The two ends of the conveyor roller 52 are rotatably connected to the conveyor roller frames 51 on the left and right sides. A second adjusting screw 43 that passes through the cover plate 40 is rotatably connected to the conveyor roller frame 51. The second adjusting screw 43 is threadedly connected to the cover plate 40. Rotating the second adjusting screw 43 can adjust the spacing of the upper and lower conveyor rollers 52 according to the thickness of the sheet metal parts.

[0026] Reference Figure 1Two feed roller frames 32 are fixed at the rear end of the housing 30, and a feed support roller 33 is rotatably connected between the two feed roller frames 32. Two discharge support rollers 35 are fixed at the front end of the housing 30, and a discharge roller frame 36 is rotatably connected between the two discharge support rollers 35. The arrangement of the feed support rollers 33 and the discharge roller frame 36 can prevent sheet metal parts from touching the edge of the housing 30 when entering the housing 30.

[0027] Reference Figure 1 , Figure 4 Two connecting plates 31 are fixed to the lower end face of the housing 30. The two connecting plates 31 abut against the inner sides of the two side plates 11 respectively. A central shaft 15 located below the feed support roller 33 is fixed between the two side plates 11. The central shaft 15 passes through the two connecting plates 31 and is rotatably connected to them. Each of the two connecting plates 31 is provided with a left-right through limiting groove 37. The limiting groove 37 is located below the pressure roller 53. The limiting groove 37 is arc-shaped and its center coincides with the axis of the central shaft 15. The sliding cooperation between the limiting rod 14 and the limiting groove 37 can limit the extreme position of the angle adjustment of the flattening mechanism. A limiting rod 14 passing through the corresponding limiting groove 37 is fixed to the inner side of the side plate 11. The axis of the lifting screw 21 is aligned with the line connecting the two limiting rods 14.

[0028] Reference Figure 1 , Figure 2 , Figure 4 A support plate 23 is provided on the upper side of the fixed plate 12. Two symmetrically arranged frame plates 20 are fixed between the support plate 23 and the fixed plate 12. The upper half of the lifting screw 21 is a smooth rod and the lower half is threaded. The rotating handle 22 is fixed to the smooth rod part of the lifting screw 21. The smooth rod part of the lifting screw 21 passes through the support plate 23.

[0029] In use, this utility model adjusts the height of the flattening mechanism's discharge end according to the processing position height of the sheet metal processing equipment. By rotating the handle 22, the lifting screw 21 rotates, causing it to rise (or fall) vertically. The end of the housing 30 away from the central axis 15 rises (or falls) with the upper end of the lifting screw 21, causing the housing 30 to rotate around the central axis 15. This adjusts the height of the end of the housing 30 away from the central axis 15, thereby reducing the height difference between the end of the housing 30 away from the central axis 15 and the sheet metal processing equipment.

[0030] Then, the motor in the power module 34 is started, which causes the conveying roller 52 and the pressure roller 53 to rotate simultaneously. At this time, the sheet metal part is fed into the housing 30 from the feeding support roller 33. The sheet metal part is flattened by the pressure rollers 53 on both sides. The sheet metal part is conveyed by the rotation of the conveying rollers 52 on both sides. After being flattened, the sheet metal part is sent out from the end near the discharge support roller 35 to the sheet metal processing equipment. By adjusting the angle of the flattening mechanism, the angle of the sheet metal output from the flattening mechanism changes to adapt to the angle input by the subsequent processing equipment, so as to prevent the sheet metal from bending due to the difference in height and distance between the two.

[0031] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
