Description

Technical Field

[0001] The invention relates to the technical field of metal sheet planing processing, in particular to a metal sheet bidirectional planing machine. Background Art

[0002] Metal sheets refer to thin metal sheets. Common metal sheets include aluminum sheets, stainless steel sheets, iron sheets, etc. They are widely used in many industrial fields. In the processing of metal sheets, V-grooving is a common process. For example, when two metal sheets need to be welded, V-grooving can make the welding process smoother. In some processing processes, V-grooves can also be used as precise positioning reference lines to facilitate further cutting, stamping or forming operations. In general, V-grooving metal sheets is used to improve processing efficiency and welding quality, facilitate subsequent forming, welding, bending and cutting operations, and reduce material waste and costs.

[0003] To make a V-shaped groove, a sheet metal notching machine is needed. For example, a sheet metal bidirectional notching machine and its use method are disclosed in China's authorized publication number CN117680751B. The traditional sheet metal notching machine mainly includes a machine base and a movable cutter head. The movable cutter head is used to make a V-shaped groove on the surface of the sheet metal placed on the machine base. However, the traditional sheet metal notching machine has many inconveniences in use: 1. When the traditional sheet metal slotting machine slots the sheet metal, during the process of the knife holder moving to slot the sheet, since the vertical position of the planer is fixed, the slot depth of the thinner sheet metal will be shallower than that of the thicker sheet metal. The inconsistent slot depth will cause the surface of the sheet metal to be uneven, affecting the appearance quality of the final product. In addition, for metal parts that need to be spliced ​​or bonded, the uneven slot will cause uneven gaps at the joints; 2. It is critical to position the metal sheet during the grooving process. Existing metal sheet grooving machines often add special limit components to limit the metal sheet in order to prevent the metal sheet from shifting during the grooving process, resulting in grooving failure and waste of raw materials. The original limit components usually only have the function of limiting the metal sheet, and are not convenient for limiting metal sheets of different sizes, which shows the disadvantage of single function.

[0021] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention will be further described below in conjunction with the embodiments.

[0023] Example: Refer to Figures 1 to 7A bidirectional grooving machine for metal sheets comprises a metal sheet body and a conveying mechanism 1 for conveying the metal sheet body. Specifically, the conveying mechanism 1 comprises two mounting uprights 11 symmetrically arranged at intervals, the lower ends of the two mounting uprights 11 are fixedly connected with a plurality of supporting legs 12, a plurality of rotating shafts 13 are rotatably arranged between the two mounting uprights 11, the shaft body of each rotating shaft 13 is fixedly sleeved with a conveying roller 14, a conveying motor 15 is fixedly installed on one of the mounting uprights 11, the output end of the conveying motor 15 is coaxially fixedly connected with one of the rotating shafts 13, the ends of the plurality of rotating shafts 13 away from the conveying motor 15 all pass through the mounting uprights 11 and are fixedly sleeved with sprockets 16, the outer sides of the plurality of sprockets 16 are rotatably sleeved with chains 17, and through the cooperation of the plurality of sprockets 16 and the chain 17, a conveying motor 15 can be used to drive the plurality of conveying rollers 14 to convey the metal sheet body.

[0024] The upper end of the conveying mechanism 1 is also provided with a longitudinal parameter positioning mechanism 2. Specifically, the longitudinal parameter positioning mechanism 2 includes a mounting support plate 21 fixedly connected to the upper end of the conveying mechanism 1. The mounting support plate 21 is slidingly connected to a first lifting plate 22 at one end close to the conveying mechanism 1. The first lifting plate 22 is symmetrically slidingly connected to two first vertical rods 23, and the two first vertical rods 23 are both arranged through the first lifting plate 22. The lower ends of the two first vertical rods 23 are commonly fixedly connected to a mounting frame 24. The lower end of the mounting frame 24 is rotatably provided with an adaptive adjustment roller 25. The second lifting plate 27 is slidably connected to the end of the mounting support plate 21 close to the conveying mechanism 1, and a plurality of special-shaped grooves 211 are provided at the end of the mounting support plate 21 close to the conveying mechanism 1. The ends of the first lifting plate 22 and the second lifting plate 27 are fixedly connected with special-shaped blocks 271 slidably connected to the special-shaped grooves 211. The width of the special-shaped grooves 211 close to the conveying mechanism 1 is smaller than the width of the end away from the conveying mechanism 1. The special-shaped grooves 211 limit the special-shaped blocks 271 to achieve the limitation of the first lifting plate 22 and the second lifting plate 27 on the mounting support plate 21.

[0025] A plurality of cross bars 26 are fixedly connected between the first lifting plate 22 and the second lifting plate 27. Two second vertical bars 28 are symmetrically fixedly connected to the lower end of the second lifting plate 27. A mounting block 29 is fixedly connected to the lower ends of the two second vertical bars 28. The thickness of the metal sheet is adaptively adjusted by the adaptive adjustment roller 25. The first lifting plate 22 rises to different heights according to the thickness of the metal sheet, and the second lifting plate 27 and the mounting block 29 are driven to rise to a certain height by the two cross bars 26.

[0026] The bidirectional grooving mechanism 4, specifically, the bidirectional grooving mechanism 4 includes two first equipment blocks 45 symmetrically slidably arranged at the lower end of the mounting block 29, a guide groove 41 is opened at the lower end of the mounting block 29, a bidirectional threaded rod 42 is rotatably connected in the guide groove 41, a rotating motor 43 for driving the bidirectional threaded rod 42 to rotate is fixedly installed on one side of the mounting block 29, the rod body of the bidirectional threaded rod 42 is symmetrically threadedly connected to two threaded sleeve blocks 44, and the first equipment block 45 is fixedly arranged at the lower end of the threaded sleeve block 44, and the upper surface grooving tool 49 can move with the movement of the threaded sleeve block 44, to ensure that the upper surface grooving tool 49 can groove the metal sheet.

[0027] The guide groove 41 is square in shape, and the threaded sleeve 44 is slidably connected to the guide groove 41 . The square guide groove 41 can limit the threaded sleeve 44 , ensuring that the rotation of the bidirectional threaded rod 42 can drive the two threaded sleeves 44 to move away from or relative to each other.

[0028] The opposite ends of the two first equipment blocks 45 are fixedly connected with connecting rods 47, and the opposite ends of the two connecting rods 47 are fixedly connected with second equipment blocks 48. The first equipment block 45 is connected to the second equipment block 48 through the connecting rods 47. When the side grooving tool 46 is adjusted, the upper surface grooving tool 49 moves accordingly.

[0029] The second equipment block 48 is connected to the lower end of the mounting block 29 in a limiting sliding manner. A plurality of limiting grooves 482 are provided at the lower end of the mounting block 29, and the plurality of limiting grooves 482 are all configured to be wide at the top and narrow at the bottom. A plurality of limiting blocks 481 are fixedly connected to the upper end of the second equipment block 48 in a limiting sliding manner with the limiting grooves 482. The plurality of limiting grooves 482 limit the vertical positions of the plurality of limiting blocks 481, which ensures the stability of the horizontal movement of the second equipment block 48 on the one hand, and can ensure the smoothness of the grooves on the upper surface of the metal sheet by the upper surface groover 49 on the other hand.

[0030] The lower ends of the two first equipment blocks 45 are fixedly embedded with side groove planing tools 46, and the opposite ends of the two second equipment blocks 48 are fixedly installed with upper surface groove planing tools 49. DC high-speed motors are fixedly embedded on the first equipment block 45 and the second equipment block 48. The side groove planing tools 46 and the upper surface groove planing tools 49 are of conical design, and the side groove planing tools 46 and the upper surface groove planing tools 49 are connected to the DC high-speed motor. When grooving, the DC high-speed motor drives the side groove planing tools 46 and the upper surface groove planing tools 49 to rotate.

[0031] The distance between the two first equipment blocks 45 is adjusted according to the width of the metal sheet. During the adjustment, the rotating motor 43 drives the bidirectional threaded rod 42 to rotate, causing the distance between the two threaded sleeve blocks 44 to change, so that the two side grooving tools 46 on the two first equipment blocks 45 can adjust their spacing according to the width of the metal sheet, so that they can be suitable for side grooving of metal sheets of different widths.

[0032] The lateral parameter positioning mechanism 5 includes two support rods 51 symmetrically fixedly connected at one end of the two first equipment blocks 45 close to the adaptive adjustment roller 25, and the other end of the support rod 51 is fixedly connected to a fixed plate 52, and the opposite ends of the two fixed plates 52 are fixedly connected to multiple lateral return springs 53, and the other ends of the multiple lateral return springs 53 are commonly fixedly connected to a limit plate 54. When the spacing between the two upper surface planing cutters 49 is adjusted by the lateral parameter positioning mechanism 5, the two first equipment blocks 45 slide relative to each other, and the two support rods 51 drive the two fixed plates 52 to move relative to each other, so that the two limit plates 54 can be aligned. The metal sheets of different widths are limited. When the auxiliary wheels 59 on the two limiting plates 54 abut against the metal sheets of different widths, the distance between the two side grooving tools 46 is the same as the width of the metal sheets. The two side grooving tools 46 continue to move relative to each other. The length of the scale rod 57 (with a scale on the surface) extending out of the fixed plate 52 through the through hole 56 is the depth of the side grooving. While the side grooving depth can be controlled, the two limiting plates 54 limit the horizontal direction of the metal sheets, and the rolling contact with the metal sheets by multiple auxiliary wheels 59 replaces the sliding contact with the limiting plates 54, thereby reducing the friction of the metal sheets during the transportation process.

[0033] A plurality of guide rods 55 are fixedly connected to opposite ends of the two limit plates 54 , and the plurality of transverse return springs 53 are located outside the guide rods 55 , so as to avoid the plurality of transverse return springs 53 from easily generating elastic deformation.

[0034] A plurality of mounting grooves 58 are spaced apart at opposite ends of the two limit plates 54, and an auxiliary wheel 59 is rotatably installed in each mounting groove 58. The plurality of auxiliary wheels 59 are in rolling contact with the metal sheet instead of the sliding contact between the limit plates 54 and the metal sheet, thereby reducing the friction of the metal sheet during the conveying process and ensuring smooth conveying of the metal sheet.

[0035] Two scale rods 57 are symmetrically fixedly connected to the rear ends of the two limit plates 54, and a through hole 56 slidably connected to the scale rod 57 is opened on the fixed plate 52, and a scale is set on the scale rod 57. When the auxiliary wheels 59 on the two limit plates 54 abut against metal sheets of different widths, the distance between the two side groovers 46 is the same as the width of the metal sheet, and the two side groovers 46 continue to move relative to each other. The length of the scale rod 57 (with a scale on the surface) extending from the fixed plate 52 through the through hole 56 is the depth of the side groove.

[0036] The invention also includes a fixing mechanism 3 for positioning the height of the bidirectional grooving mechanism 4. The fixing mechanism 3 includes two fixing rods 31 fixedly connected to the mounting support plate 21. The other ends of the two fixing rods 31 are fixedly connected to the mounting box 32. The upper ends of the two first vertical rods 23 pass through the bottom wall of the mounting box 32 and are fixedly connected to a moving plate 33. The moving plate 33 is slidably connected to the inner wall of the mounting box 32. A plurality of longitudinal return springs 34 are fixedly connected between the moving plate 33 and the top wall of the mounting box 32. A magnetorheological fluid 35 is arranged in the mounting box 32. The magnetorheological fluid 35 is a A smart material, which belongs to a kind of magnetic responsive fluid, has the characteristic that its rheological properties (such as viscosity and fluidity) change reversibly under the action of an external magnetic field. The working principle of the magnetorheological fluid 35 is to use magnetic particles (usually ferromagnetic particles) dispersed in the liquid. These particles can quickly change the viscosity and elasticity of the fluid under the action of an external magnetic field, thereby achieving control of the fluidity of the fluid. The magnetorheological fluid 35 is always located below the moving plate 33, and a magnetic field generator is fixedly embedded at the lower end of the moving plate 33. The magnetic field generator is used to adjust the rheological properties of the magnetorheological fluid.

[0037] A zero-speed switch 36 is fixedly installed on the upper end of the movable plate 33. The signal of the zero-speed switch 36 is connected to the controller, and the controller is electrically connected to the magnetic field generator. The thickness of the metal sheet is adaptively adjusted through the adaptive adjustment roller 25 in the longitudinal parameter positioning mechanism 2, and the position of the upper surface grooving tool 49 is automatically adjusted according to its thickness to ensure that the depth of the grooving of metal sheets of different thicknesses is consistent. The distance between the lower end surface of the adaptive adjustment roller 25 and the lower end surface of the upper surface grooving tool 49 is the depth of the upper surface grooving. After the tool position adjustment is completed, the rising speed of the movable plate 33 is reduced to 0, and the zero-speed switch 36 controls the magnetic field generator in the installation box 32 to apply a magnetic field, fix the vertical position of the two-way grooving mechanism 4, and also fix the position of the adaptive adjustment roller 25. The adaptive adjustment roller 25 can limit the metal sheet in the vertical direction during transportation to ensure the accuracy of grooving of metal sheets of different thicknesses.

[0038] The specific working principle of the present invention is as follows: First of all, it should be noted that when no magnetic field is applied to the magnetorheological fluid 35 , the thickness of the metal sheet is greater than the minimum distance between the conveying roller 14 and the adaptive adjustment roller 25 , and less than the distance between the horizontal center axes of the conveying roller 14 and the adaptive adjustment roller 25 .

[0039] When in use, the metal sheet is first placed on the upper end of the conveying roller 14 and conveyed in the direction of the two-way grooving mechanism 4. During the conveying process, the thickness of the metal sheet is adaptively adjusted by the adaptive adjustment roller 25, the first lifting plate 22 rises to a certain height, and the second lifting plate 27 and the mounting block 29 are driven to rise to a certain height by the two cross bars 26, and the two upper surface grooving cutters 49 rise accordingly (the lower end surface of the upper surface grooving cutter 49 is lower than the lower end surface of the adaptive adjustment roller 25, and the length of the upper surface grooving cutter 49 below the adaptive adjustment roller 25 is the depth of the groove on the upper surface of the metal sheet). Since the upper surface grooving cutter 49 can remain relatively still with the adaptive adjustment roller 25, V-shaped grooves of the same depth can be opened on metal sheets of different thicknesses; When the adaptive adjustment roller 25 is completely on the upper surface of the metal sheet, the adaptive adjustment roller 25 no longer rises, and the rising speed of the moving plate 33 drops to zero. The zero-speed switch 36 controls the magnetic field generator in the installation box 32 to apply a magnetic field, and the viscosity of the magnetorheological fluid 35 increases rapidly, fixing the vertical position of the bidirectional grooving mechanism 4 and the position of the adaptive adjustment roller 25. The adaptive adjustment roller 25 can limit the metal sheet in the transportation process in the vertical direction, ensuring that the grooving depth of the metal sheets with different thicknesses is consistent; The distance between the two first equipment blocks 45 is adjusted according to the width of the metal sheet. During the adjustment, the rotating motor 43 drives the bidirectional threaded rod 42 to rotate, driving the distance between the two threaded sleeve blocks 44 to decrease. Since the auxiliary wheels 59 on the two limiting plates 54 abut against metal sheets of different widths, the distance between the two side grooving cutters 46 is the same as the width of the metal sheet, so that the present invention can be applied to the side grooving of metal sheets of different widths. While adjusting the spacing between the two upper surface grooving tools 49 through the lateral parameter positioning mechanism 5, the two first equipment blocks 45 slide relative to each other, and the two fixed plates 52 are driven to move relative to each other through the two support rods 51, so that the two limit plates 54 can limit the metal sheets of different widths. When the auxiliary wheels 59 on the two limit plates 54 abut against the metal sheets of different widths, the distance between the two side grooving tools 46 is the same as the width of the metal sheets. The two side grooving tools 46 continue to move relative to each other. The length of the scale rod 57 (with a scale on the surface) extending out of the fixed plate 52 through the through hole 56 is the depth of the side grooving. The side grooving depth can be controlled. At the same time, the two limit plates 54 limit the horizontal direction of the metal sheets. By adding a plurality of auxiliary wheels 59 to roll in contact with the metal sheets instead of sliding in contact with the limit plates 54, the friction of the metal sheets during transportation is reduced.
