[0023] The following details the specific implementation manners of the present utility model in conjunction with the accompanying drawings. It should be understood that the specific implementation manners described herein are only for explaining and understanding the present utility model, and are not used to limit the present utility model.

[0024] Please refer to Figures 1-4 , Figure 1 which is a schematic perspective view of the bending device provided by the embodiment of the present utility model; Figure 2 which is a schematic perspective view of a part of the bending device provided by an embodiment of the present utility model;

[0025] Figure 3 is Figure 1 the enlarged view at position A in Figure 4 is Figure 2An enlarged view of part B in [the figure]. The bending device 1 of the present utility model includes a support frame 11, a bending assembly 12, and a support assembly 13. The bending assembly 12 includes a bending roller 121, two sets of adjusting rails 122, and two sets of adjusting wheels 123. Adjusting grooves 111 adapted to the size of the adjusting wheels 123 are provided on both sides of the support frame 11. The two sets of adjusting rails 122 are respectively fixed in the adjusting grooves 111 on both sides of the support frame 11. The two sets of adjusting wheels 123 respectively move along the adjusting grooves 111 on the two sets of adjusting rails 122. Both ends of the bending roller 121 are connected to the adjusting wheels 123 to move synchronously with the two sets of adjusting wheels 123. The support assembly 13 includes a support roller 131 and a tensioning roller 132. Both ends of the support roller 131 are rotatably connected to both sides of the support frame 11. Both ends of the tensioning roller 132 are rotatably connected to both sides of the support frame 11. The tensioning roller 132 is located between the support roller 131 and the bending roller 121, and the height of the tensioning roller 132 is higher than that of the support roller 131 and the bending roller 121.

[0026] When performing a bending operation on a resin-coated abrasive tool, first place one end of the abrasive tool on the support roller 131, and make the abrasive tool bypass the upper side of the tensioning roller 132 and then wrap around the lower side of the bending roller 121, so that the bending roller 121 bends the abrasive tool to improve the flexibility of the abrasive tool under the action of the bending roller 121. During the bending process, by rotating the adjusting wheel 123, the adjusting wheel 123 moves along the adjusting groove 111 in the adjusting rail 122, thereby realizing precise adjustment of the position of the bending roller 121. After the position of the bending roller 121 is adjusted, the distance and angle between the bending roller 121 and the tensioning roller 132 change, and thus the bending force and bending angle of the bending roller 121 on the abrasive tool change, so that the operator can adjust the position of the bending roller 121 according to the flexibility requirements of the abrasive tool, so that the abrasive tool after the bending operation can meet the required flexibility requirements.

[0027] By controlling the rotation angle of the adjusting wheel 123 to make the position of the bending roller 121 change correspondingly, it is convenient for the operator to record the position of the adjusting wheel 123 and the flexibility of the bent abrasive tool, so as to obtain the comparison relationship between the flexibility of the abrasive tools bent at each position. When abrasive tools with different flexibilities are needed subsequently, the position of the adjusting wheel 123 can be adjusted according to the recorded information, thereby improving the bending efficiency of the abrasive tool and reducing the bending error rate of the abrasive tool at the same time.

[0028] In an embodiment of the present utility model, rotating shafts 1211 are provided at both ends of the kneading roller 121. Splines are provided on the rotating shafts 1211. A jack for inserting the rotating shafts 1211 is formed on the adjusting wheel 123, and a keyway adapted to the splines is provided on the jack. When the rotating shafts 1211 are inserted into the jacks, the splines are inserted into the keyways.

[0029] The adjusting wheel 123 and the rotating shafts 1211 are connected by splines and keyways. Thus, when the adjusting wheel 123 is rotated, the adjusting wheel 123 can drive the rotating shafts 1211 to rotate synchronously. At the same time, when the adjusting wheel 123 rotates, it moves on the adjusting rail 122 and drives the kneading roller 121 to move synchronously with the adjusting wheel 123, so as to adjust the position of the kneading roller 121, thereby changing the kneading force and kneading angle of the kneading roller 121 on the grinding tool, and realizing the flexibility adjustment of the grinding tool.

[0030] In an embodiment of the present utility model, the kneading roller 121 includes a kneading section and a connecting section. The kneading section is rotatably connected to the rotating shafts 1211, and the connecting section is inserted and connected to the rotating shafts 1211.

[0031] By inserting and connecting the connecting section to the rotating shafts 1211, when the adjusting wheel 123 is rotated to drive the kneading roller 121 to displace, the connecting section can rotate synchronously with the rotating shafts 1211 during the movement. By rotatably connecting the kneading section to the rotating shafts 1211, when the adjusting wheel 123 is rotated to drive the kneading roller 121 to displace, the kneading section will not be affected by the rotation of the rotating shafts 1211 during the movement, that is, the kneading section will not rotate synchronously with the rotating shafts 1211, so that the kneading section can still knead the grinding tool during the movement, improving the kneading efficiency of the kneading device 1.

[0032] In an embodiment of the present utility model, the adjusting wheel 123 is a gear, the adjusting rail 122 is a rack, and the adjusting wheel 123 remains engaged with the rack when moving on the rack.

[0033] In an embodiment of the present utility model, the kneading assembly 12 further includes an adjusting handle 124. A jack for inserting the adjusting handle 124 is provided on the end face of the adjusting wheel 123. The jack is provided at an eccentric position of the adjusting wheel 123. The handle is detachably connected to the adjusting wheel 123 through the jack, so that an operator can insert the adjusting handle 124 into the jack and hold the handle to rotate the adjusting wheel 123, and then move the adjusting wheel 123 on the adjusting rail 122 to realize the position adjustment of the kneading roller 121.

[0034] In an embodiment of the present utility model, a first scale 112 is provided at a position of the support frame 11 corresponding to the adjustment groove 111, and an annular second scale 1231 is provided on the end face of the adjustment wheel 123, so that an operator can rotate the adjustment wheel 123 according to the first scale 112 and the second scale 1231 to achieve precise adjustment of the position of the kneading roller 121, and thus the flexibility of the kneaded mold can better meet the requirements.

[0035] In an embodiment of the present utility model, the kneading assembly 12 further includes a locking disc 125, which is threadedly connected to the rotating shaft 1211. Rotating the locking disc 125 can make the locking disc 125 fit on the surface of the support frame 11, so that when the locking disc 125 fits on the surface of the support frame 11, the position of the kneading roller 121 can be fixed, so as to prevent the adjustment wheel 123 from rotating on its own on the adjustment rail 122, resulting in a change in the position of the kneading roller 121, and further affecting the kneading effect of the mold.

[0036] In an embodiment of the present utility model, the locking disc 125 is a transparent locking disc 125, so that an operator can view the second scale 1231 on the support frame 11 through the transparent locking disc 125, which is convenient for the operator to precisely adjust the position of the kneading roller 121. Moreover, an anti-slip layer is provided on the surface of the locking disc 125 close to the support frame 11, so that when the locking disc 125 is rotated and fits on the surface of the support frame 11, it can fit on the surface of the support frame 11 under the action of the anti-slip layer, improving the friction between the locking disc 125 and the support frame 11 to prevent the adjustment wheel 123 from accidentally rotating and affecting the position accuracy of the kneading roller 121 and the flexibility effect of the mold.

[0037] In an embodiment of the present utility model, tension shafts 1321 are provided at both ends of the tension roller 132. The support assembly 13 further includes a tension connecting member 133, a tension elastic member 134, and an adjustment screw 135. The tension connecting member 133 is sleeved on the tension shaft 1321. A sliding groove for the tension connecting member 133 to slide is provided on the support frame 11. A support platform 113 is provided in the sliding groove. One end of the adjustment screw 135 is rotatably connected to the tension connecting member 133, and the other end passes through the support platform 113 and is threadedly connected to a nut. The tension elastic member 134 is disposed between the tension connecting member 133 and the support platform 113 and is sleeved outside the adjustment screw 135.

[0038] By sleeving a tension connecting member 133 on the tension shaft 1321, rotatably connecting the adjusting screw 135 with the tension connecting member 133, passing the adjusting screw 135 through the support table 113 and then threadedly connecting it with a nut, the distance between the tension connecting member 133 and the support table 113 can be adjusted by rotating the nut, so as to make the tension roller 132 support the abrasive tool with different degrees of tension. By sleeving the tension elastic member 134 on the adjusting screw 135, the tension roller 132 can compress the tension elastic member 134 under the action of an external force, avoiding damage to the abrasive tool caused by excessive tension force on the abrasive tool. After adjusting the distance between the tension connecting member 133 and the support table 113, the tension elastic member 134 can also be compressed to different degrees, so as to realize the adjustment of the tension pre-tightening force of the tension roller 132, so that the tension roller 132 tensions the abrasive tool under the action of the pre-tightening force, avoiding the phenomenon of the abrasive tool being too tight or too loose during the conveying process.

[0039] In the embodiment of the present invention, the support assembly 13 further includes a winding roller 136 and a winding driving member. The winding driving member is fixed on the support frame 11 and connected to the winding roller 136 to drive the winding roller 136 to rotate, and wind up the abrasive tool receipt after passing through the bending roller 121 on the winding roller 136, which is convenient for the operator to sort and place the wound abrasive tool, and reduces the occupied space of the abrasive tool at the operation site.
