Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of steel plastic pipe manufacturing equipment, in particular to a small specification galvanized steel strip grinding machine. BACKGROUND

[0002] The galvanized steel strip reinforced steel plastic pipe with galvanized steel strip as the intermediate reinforcing layer is an important steel plastic composite pipe, and compared with the water supply galvanized inner coating plastic composite steel pipe with seamless steel pipe as the intermediate reinforcing layer, it has the advantages of saving steel and low cost. In the production of the galvanized steel strip reinforced steel plastic pipe, the galvanized layer on the edge of the galvanized steel strip needs to be removed by grinding before the galvanized steel strip is curled and formed into an intermediate reinforcing steel pipe layer. The size and stability of the grinding force between the grinding wheel and the steel strip have an important influence on the grinding quality. The existing grinding equipment generally adjusts the grinding force by a manual mechanism. Due to the change in the thickness of the steel strip, the grinding force cannot be uniform and consistent, which affects the uniformity of grinding.

[0003] The Chinese patent document with the name of "A steel strip edge grinding machine" and the announcement number of CN 102785154 B announced on July 16, 2014 discloses a metal strip surface grinding equipment, which has the following problems: 1. The motor fixing form of the grinding machine is a lever structure, which grinds the steel strip through the gravity of the motor and the counterweight. For thin and narrow steel strips, the steel strip is easy to bend and deform due to insufficient strength and front and rear tension, which can easily lead to uneven grinding of the front and rear surfaces; 2. The counterweight is inconvenient to adjust, and the front surface can be ground to the position while the rear surface cannot be ground. SUMMARY

DETAILED DESCRIPTION

[0037] The application will be described in detail below with reference to the drawings.

[0038] The structure of the small-sized galvanized steel strip grinding machine provided by the embodiment is shown in Figure 1 and includes a workbench, a grinding adjustment mechanism, a steel strip support adjustment mechanism, a guide adjustment mechanism and a steel strip tensioning mechanism.

[0039] The workbench 1 provides support for the entire grinding machine and support for the installation of other functional mechanisms.

[0040] The grinding adjustment mechanism has two pairs, and each pair of grinding motor adjustment mechanisms is symmetrically distributed on both sides of the steel strip moving track. As shown in Figure 2 the grinding adjustment mechanism includes two-axis moving mechanisms, a grinding motor 2 and a grinding wheel 3, and the two-axis moving mechanisms include an X-axis moving mechanism and a Z-axis moving mechanism. The moving track of the X-axis moving mechanism is perpendicular to the steel strip moving track. The X-axis moving mechanism includes an X-axis sliding table bottom plate 4, an X-axis sliding table 5 and an X-axis hand wheel 6. The Z-axis moving mechanism includes a Z-axis sliding table bottom plate 7, a Z-axis sliding table 8 and a Z-axis hand wheel 9. The Z-axis sliding table bottom plate 7 is fixed to the X-axis sliding table 5, the grinding motor 2 is installed on the Z-axis sliding table 8, and the grinding wheel 3 is sleeved on the output shaft of the grinding motor 2. In each pair of grinding motor adjustment mechanisms, the two X-axis sliding table bottom plates 4 are symmetrically fixed to the workbench, and the two grinding wheels 3 are opposite to each other.

[0041] When it is necessary to grind steel strips of different widths, the distance between each pair of grinding wheels needs to be adjusted. At this time, the X-axis hand wheel 6 can be rotated, the X-axis sliding table 5 moves in the X-axis direction, the Z-axis moving mechanism moves in the X-axis direction driven by the X-axis sliding table 5, and the grinding wheel 3 moves in the X-axis direction driven by the Z-axis moving mechanism, thereby achieving the adjustment of the distance between each pair of grinding wheels 3.

[0042] When it is necessary to adjust the height of the grinding wheel, the Z-axis hand wheel 9 can be rotated at this time, the Z-axis sliding table 8 moves in the Z-axis direction, the grinding motor 2 moves in the Z-axis direction driven by the Z-axis sliding table 8, and the grinding wheel 3 moves in the Z-axis direction driven by the grinding motor 2, thereby achieving the adjustment of the height of the grinding wheel 3.

[0043] The steel strip support adjustment mechanism includes a pair of supports and a pair of steel strip limiting adjustment mechanisms. The pair of supports are symmetrically installed on the front and rear parts of the workbench, and the pair of steel strip limiting adjustment mechanisms are centrally symmetrically distributed. Each pair of grinding motor adjustment mechanisms is symmetrically distributed on both sides of the corresponding steel strip support adjustment mechanism. The support includes four vertical columns 10, and the lower ends of the four vertical columns 10 are connected to the front or rear part of the workbench.

[0044] The steel strip limiting adjustment mechanism includes an up-down limiting adjustment mechanism for limiting the up-down movement of the steel strip and a left-right limiting adjustment mechanism for limiting the left-right movement of the steel strip.

[0045] As shown in Figures 3-6 the up-down limiting mechanism includes a grinding moving plate 11, a grinding fixed plate 12, a tension spring 13 and a guide assembly. As shown inFigures 4-5 As shown, the polishing movable plate 11 and the polishing fixed plate 12 are both in the shape of an I-beam, and the lower ends of the four columns 10 of each support are fixedly connected to the four corners of the corresponding polishing fixed plate 12. The polishing movable plate 11 and the polishing fixed plate 12 are horizontally arranged, the polishing fixed plate 12 and the polishing movable plate 11 are opposite to each other, and the space on both sides of the polishing movable plate 11 and the polishing fixed plate 12 constitutes a polishing working position. The polishing movable plate 11 is symmetrically provided with a first guide sliding groove 18 on both sides, and the length direction of the first guide sliding groove 18 is parallel to the X-axis direction.

[0046] The guide assembly includes four guide columns 14, four guide sleeves 15 and a guide connecting plate 16. One end of the four guide columns 14 is connected to the four corners of the polishing fixed plate 12, and the other end of the four guide columns 14 is connected to the guide connecting plate 16. The four guide columns 14 respectively penetrate the four corners of the polishing movable plate, the four guide sleeves 15 are respectively sleeved on the four guide columns 14, and the four corners of the polishing movable plate 11 are fixedly connected to the four guide sleeves 15.

[0047] The tension spring 13 is provided in pairs, and the two tension springs 13 are symmetrically arranged. One end of the two tension springs 13 is fixed to the polishing fixed plate 12, and the other end of the two tension springs 13 is fixed to the polishing movable plate 11. Since the tension spring 13 always has a tension force to pull the polishing movable plate 11, the polishing wheel 3 and the steel belt are always kept in tension. When the outer diameter of the polishing wheel 3 becomes smaller due to wear, the tension spring 13 pulls the polishing movable plate 11 to always press the steel belt, so that the steel belt is always in full contact with the polishing wheel 3 for polishing.

[0048] In the two upper and lower limiting mechanisms, the guide connecting plate 16, the polishing movable plate 11 and the polishing fixed plate 12 of one of the upper and lower limiting mechanisms are arranged in sequence from top to bottom, and the guide connecting plate 16, the polishing movable plate 11 and the polishing fixed plate 12 of the other of the upper and lower limiting mechanisms are arranged in sequence from bottom to top.

[0049] The left and right limiting adjustment mechanism includes two pairs of first cam guides 17, two pairs of sliding assemblies, a pair of mounting strips 22 and a pair of wear-resistant strips 23.

[0050] The sliding assembly includes a first screw rod 19, a first adjusting nut 20 and a first sliding block 21. The first sliding block 21 is in the shape of T, the first screw rod 19 penetrates the first sliding block 21, the first screw rod 19 is in clearance fit with the first sliding block 21, and the first adjusting nut 20 is threadedly connected to one end of the first screw rod 19. In each pair of sliding assemblies, the two first screw rods 19 movably penetrate the corresponding first guide sliding groove 18, the two first sliding blocks 21 are respectively in sliding connection with the corresponding first guide sliding groove 18, and the two first sliding blocks 21 are fixed to the polishing movable plate 11 through the first adjusting nut 20.

[0051] Both the mounting strips 22 and the wear strips 23 are parallel to the steel belt's trajectory. Each mounting strip 22 is positioned between its corresponding wear strip 23 and the grinding plate 11, and each wear strip 23 is positioned between its corresponding mounting strip 22 and the grinding plate 12. Each mounting strip 22 has two ends connected to the other ends of two first screws 19, which are located along a line parallel to the steel belt's trajectory. The two wear strips 23 are fixedly connected to the mounting strips 22 by screws. The wear strips 23 are wear-resistant and easy to replace, preventing damage to the grinding plate 11 caused by prolonged contact between the grinding wheel 3 and the grinding plate 11. The studs of the two first cam guides 17, which are located along a line parallel to the steel belt's trajectory, are threadedly connected to their corresponding mounting strips 22.

[0052] When it is necessary to grind steel belts 40 of different widths, loosen the two first adjusting nuts 20 distributed on the straight line parallel to the steel belt movement trajectory, and synchronously move the two first sliders 21 distributed on the straight line parallel to the steel belt movement trajectory. The first slider 21 drives the two first cam guides 18 distributed on the straight line parallel to the steel belt movement trajectory to move through the mounting bar 22, thereby realizing the adjustment of the distance between each pair of first cam guides 18, and then adapting to steel belts of different widths.

[0053] There is a pair of guide adjustment mechanisms, which are symmetrically installed on the front and rear sides of the workbench. Figures 7-8 As shown, the guide adjustment mechanism includes a guide bracket and a pair of symmetrically arranged guide wheel adjustment assemblies.

[0054] like Figure 8 As shown, the guide bracket includes a guide support horizontal plate 27 and two guide support vertical plates 28. The lower ends of the two guide support vertical plates 28 are respectively mounted on the front side or the rear side of the workbench 1, and the upper ends of the two guide support vertical plates 28 are respectively connected to the two ends of the guide support horizontal plate 27. A second guide slot 29 is defined at the bottom of the guide support horizontal plate 27. The second guide slot 29 is a through slot, and the length direction of the second guide slot 19 is parallel to the X-axis direction.

[0055] like Figure 9 As shown, the guide wheel adjustment assembly includes a guide wheel assembly, a second screw 24, a second adjustment nut 25, and a second slider 26. The second slider 26 is T-shaped, and the second screw 27 is vertically arranged. The second screw 24 movably passes through the second slider 26, and the second screw 24 and the second slider 26 are clearance-fitted. The second adjustment nut 25 is threadedly connected to the lower end of the second screw 24.

[0056] The guide wheel assembly includes a fixed base 30, multiple pairs of guide wheels 31, and multiple second cam guides 32. The fixed base 30 is U-shaped, with the two horizontal parts of the fixed base 30 parallel to the workbench 1, and the upper end of the second screw 24 is connected to the center of the horizontal bottom of the fixed base 30. Multiple pairs of guide wheels 31 are distributed in sequence at equal intervals along a straight line parallel to the moving track of the steel belt, and each pair of guide wheels 31 is respectively mounted on the side walls of the horizontal top and horizontal bottom of the fixed base 30 parallel to the moving track of the steel belt through bearings. The second cam guides 32 and the guide wheels 31 are arranged alternately at intervals, and the studs of the second cam guides 32 are threadedly connected to the horizontal top of the fixed base 30. In the two guide wheel assemblies, the openings of the two fixed bases 30 are directly opposite each other.

[0057] In each guide adjustment mechanism, the two second sliders 26 are slidably connected to the corresponding second guide slots 29 , and the two second sliders 26 are fixed to the bottom of the guide support horizontal plate 27 through the second adjustment nuts 25 .

[0058] When it is necessary to grind steel belts 40 of different widths, the second adjusting nut 25 can be loosened and the second slider 26 can be moved. The second slider 26 drives the fixed seat to move through the second screw 24, thereby adjusting the distance between each pair of second cam guides 32 and the distance between the two pairs of symmetrically distributed guide wheels 31, thereby adapting to steel belts of different widths, guiding steel belts of different widths, and limiting steel belts of different widths to the left and right, so that the steel belt is always located in the middle.

[0059] There is a pair of steel belt tensioning mechanisms, which are symmetrically installed on the front end and the rear end of the workbench, and a pair of guide adjustment mechanisms are distributed on the inner sides of the pair of steel belt tensioning mechanisms.

[0060] like Figures 10-11 As shown, the steel belt tensioning mechanism includes a dynamic tensioning roller 33, a fixed tensioning roller 34, and a pair of lifting mechanisms. The lifting mechanism comprises a lifting bracket 35, a lifting screw 36, a lifting handwheel 37, an upper fixing block 38, and a lower fixing block 39. The lifting bracket 35 is in an inverted U-shape, with its bottom mounted on the front or rear end of the workbench 1. The upper fixing block 38 and the lower fixing block 39 are both located within the lifting bracket. The lower fixing block 39 is fixed within the lifting bracket 35, and the upper fixing block 38 is slidably connected to the two vertical sections of the lifting bracket 35. The lifting screw 36 flexibly extends through the top of the lifting bracket 35. The lower end of the lifting screw 36 is threadedly connected to the upper fixing block 38, and the lifting handwheel 37 is fixed to the upper end of the lifting screw 36. The fixed tensioning roller 34 is fixed to the two lower fixing blocks 39 via bearings at both ends, while the dynamic tensioning roller 33 is fixed to the upper fixing block 38 via bearings at both ends.

[0061] When the tension of the steel belt needs to be adjusted, the lifting hand wheel 37 is turned, the upper fixed block 38 moves up and down, and the upper fixed block 38 drives the upper tension roller 33 to move up and down, so that the tension of the steel belt is adjusted.
