Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel production and processing equipment, in particular to a fine grinder which is suitable for grinding the surface of a relatively thin stainless steel plate by using grinding fluid to grind a grinding disc. Background Art

[0002] Thin stainless steel plates, such as those with a thickness of 0.4mm, 0.6mm or 0.8mm, often bend and deform due to improper handling during processing and transportation. Therefore, before or after the mirror effect polishing treatment, the thin stainless steel plates need to be flattened by stretching or extrusion. This makes the process complicated, but in fact, the flattening of stainless steel plates does not require too high stretching or extrusion pressure. Utility Model Content

[0003] In the prior art, the fine grinding and straightening of thin stainless steel plates are carried out in two devices, so it is necessary to transfer between the two devices. If the thin stainless steel plate is removed by a vacuum suction cup, the vacuum suction cup partially absorbs and lifts the thin stainless steel plate, but the unabsorbed part droops under the action of its own weight, which is easy to aggravate the deformation of the stainless steel plate. If manual unloading is used, there is a problem of inefficiency.

[0004] The fine grinding machine provided in the embodiment of the present application eliminates the necessary transfer between two devices, as well as the resulting waste of man-hours and the possibility of increased deformation due to transfer.

DETAILED DESCRIPTION

[0025] To enable those skilled in the art to better understand the technical solutions in this application, the following will clearly and completely describe the technical solutions in the embodiments of this application in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in this application without creative efforts shall fall within the scope of protection of this application.

[0026] Embodiment: Refer to Figure 1-4 A fine grinding machine shown in the figure, which includes a workbench 1, a grinding device 2, a gantry device 3, a straightening device 4, a cleaning device 5 and a control system. The control system is any feasible structure of the prior art and is configured to electrically control the workbench 1, the grinding device 2, the gantry device 3 and the straightening device 4 so that they perform actions according to the designed process.

[0027] The workbench 1 has an axis 11 and includes a base 12, a support table 13 screwed to the base 12, side limit baffles 14 provided on both sides of the support table 13, and an end limit baffle 15 provided at the end of the support table 13. The base 12 is any feasible structure in the prior art and is configured to support and elevate the support table 13.

[0028] The support table 13 has a certain width, and this width is formed by a slope with a higher side at the starting end and a lower side at the ending end. Preferably, the starting end side of the support table 13 is 3 - 10 cm higher than the ending end side, so that in the natural state, the thin stainless steel plate placed on the support table 13 can slide down the slope at an appropriate speed.

[0029] On both sides of the support table 13, there are support table side extension platforms 16. The support table side extension platforms 16 are lateral extension parts of the support table 13. They are screwed to the base 12 and have a lateral gap with the side of the support table 13. At the end of the support table 13, there is a support table end extension platform 17. The support table end extension platform 17 is a rear extension part of the support table 13. It is screwed to the base 12 and has an end gap with the side of the support table 13. Below the lateral gap and the end gap, there is a grinding fluid recovery groove 18 in a "冂" shape. The grinding fluid recovery groove 18 is screwed or welded and installed around the three - sided surface of the base 12.

[0030] A plurality of side limit baffles 14 are arranged on both sides of the support platform 13. The side limit baffles 14 include a limit cylinder 141 screwed and mounted on the side extension platform 16 of the support platform, and a limit push plate 142 screwed or pin-keyed and mounted on the telescopic end of the limit cylinder 141. The limit push plate 142 has a limit surface perpendicular to the slope of the support platform 13, and the bottom surface of the limit push plate 142 abuts against the surface of the support platform 13. The end of the side limit baffle 14 arranged near the end of the support platform 13 extends vertically inward to form an end limit baffle 15. The extension and retraction of the limit cylinder 141 can control the limit width formed by the limit push plate 142 to adapt to the limit fixation of thin stainless steel plates of different widths. The extension and retraction of the limit cylinder 141 can also make the end limit baffle 15 extend to block the thin stainless steel plate, or retract to allow the thin stainless steel plate to slide and fall.

[0031] Since the slope of the support platform 13 allows the thin stainless steel plate to naturally fall on the limiting surface of the end limiting baffle 15, it is only necessary to limit the three sides of the thin stainless steel plate to prevent the thin stainless steel plate from moving during the grinding process. Of course, the starting end of the side limiting baffle 14 arranged near the starting end of the support platform 13 extends vertically inward to form the limit of the other end.

[0032] The grinding device 2 is installed through the gantry device 3 so that it can move along the axis 11 and in a direction perpendicular to the axis 11. The gantry device 3 is any feasible structure in the prior art, for example, including a track, a feed head matched with the track, a pair of vertical beams, and a gantry beam assembled through the vertical beams. The gantry beam can be fixed on the vertical beam, or it can be raised and lowered along the vertical beam under the drive of the cylinder. The gantry beam has a beam track and a transverse head that can move the beam slider along the beam track. Both the feed head and the transverse head can be a screw servo mechanism or a sprocket feed mechanism. In short, the gantry device 3 can move the grinding device 2 to any position within the width range limited by the limit push plate 142 and the end limit baffle 15 on the support table 13.

[0033] The grinding device 2 includes a liquid supply system 21 and a grinding mechanism 22. The grinding mechanism 22 includes a grinding cylinder 221 screwed or welded on a crossbeam slider, a grinding head 223 mounted on the telescopic end of the grinding cylinder 221 through a pivot structure 222, and a grinding disc 224 mounted on the output end of the grinding head 223. The pivot structure 222 includes a pivot seat welded and fixedly connected to the telescopic end of the grinding cylinder 221, a pivot block mounted on the pivot seat through a pivot shaft, and the pivot block is welded and fixedly connected to the grinding head 223. By setting the pivot structure 222, the grinding head 223 and the grinding disc 224 are allowed to swing in a plane perpendicular to the support table 13, so that the grinding mechanism 22 can always perform grinding along the table surface of the support table 13.

[0034] The liquid supply system 21 includes a grinding liquid agent source (not shown in the figure), a spray head 211, a hose 212 connecting the grinding liquid agent source and the spray head 211, a pump (not shown in the figure) suitable for supplying the grinding liquid in the grinding liquid agent source to the spray head 211, and a bracket 213 suitable for fixing the spray head 211 on one side of the grinding disc 224. The grinding liquid agent source, the spray head 211, the hose 212, and the pump are any feasible structures in the prior art. The bracket 213 is fixed to the housing of the grinding machine head 223 by screwing or welding.

[0035] Preferably, the grinding liquid recovery tank 18 is connected to the grinding liquid agent source through a pump and a pipeline to recycle excess grinding liquid.

[0036] The straightening device 4 is connected to the workbench 1 at the rear, and includes a straightening device base 41, a lower support roller group 42 flush with the end of the support table 13 or the support table end extension table 17, and an upper pressure roller group 43 suitable for providing straightening pressure toward the lower support roller group 42.

[0037] The straightening device base 41 is any feasible structure in the prior art, and is configured to support and install the lower support roller set 42. The straightening device base 41 provided in this embodiment includes a base, a pair of side mounting plates arranged on both sides of the base, and a middle mounting plate arranged in the middle of the base; the lower support roller set 42 includes two lower support rollers, which are respectively installed through a pair of side mounting plates and the middle mounting plate.

[0038] The upper pressure roller group 43 is opposite to the lower support roller group 42 in the upper and lower parts, and includes a transversely arranged frame beam 431, a clamping cylinder 432 bolted and fixedly mounted on the cross beam of the frame beam 431, and a clamping roller 433 mounted on the telescopic end of the clamping cylinder 432 through a bearing. The upper pressure roller group 43 includes a plurality of clamping rollers 433 connected to each other through a coupling, and the clamping cylinder 432 includes a plurality of corresponding ones, and the telescopic end of each of the clamping cylinders 432 is connected to the coupling.

[0039] The cleaning device 5 is arranged between the workbench 1 and the straightening device 4. The cleaning device 5 comprises a sponge roller installed through the base 12 and a motor driving the sponge roller to rotate. The sponge roller cooperates with the table surface of the extension table 17 at the end of the support table, and can absorb and wipe off the residual grinding liquid on the surface of the thin stainless steel plate, so as to prevent the grinding particles in the grinding liquid from leaving scratches on the surface of the thin stainless steel plate that are not required by the design during the straightening process of the straightening device 4.

[0040] The working principle of a fine grinder provided in the embodiment of the present application is as follows:

[0041] In the initial state, the gantry device 3 is located at the starting end, the side limit baffles 14 retreat to both sides of the support platform 13, and the end limit baffles 15 are not completely retreated with the end side limit baffles 14 and can prevent the thin stainless steel plate from falling.

[0042] First, the thin stainless steel plate enters the support platform 13 by means of the roller conveyor 6 or manual feeding, and slides down along the slope of the support platform 13 until it is limited by the end limit baffle 15. At this time, the control system controls the limit cylinder 141 to push out the limit push plate 142 to clamp the thin stainless steel plate;

[0043] Then, the control system controls the grinding device 2 and the gantry device 3 to perform wet fine grinding on the surface of the thin stainless steel plate;

[0044] Then, the control system controls the gantry device 3 to retreat to the starting end, and at the same time controls the limit cylinder 141 to retract the limit push plate 142 until the end limit baffle 15 releases the blocking of the thin stainless steel plate, and the thin stainless steel plate slides down to the cleaning device 5 under the action of gravity. The cleaning device 5 is a powered sponge roller, so it can drive the thin stainless steel plate to continue to feed to the straightening device 4 while completing the surface cleaning;

[0045] Then, the thin stainless steel plate passes through the straightening device 4, and the bending correction of the thin stainless steel plate is completed under the cooperation of the lower support roller group 42 and the upper pressure roller group 43;

[0046] Finally, the refiner of this embodiment is left and the next step is entered.
