During the production process of mold steel, the edges and corners of the mold steel need to be repaired. In order to improve the efficiency of repairing the edges and corners, multi-angle trimming and grinding devices are used.

When grinding the upper and lower edge corners of the mold steel, it is necessary to change the angle of the grinding mechanism, which means that it is impossible to simultaneously grind the upper and lower edge corners of the mold steel, resulting in relatively low grinding efficiency.

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Please combine Figures 1 to 3 The multi-angle trimming and grinding device suitable for mold steel production of this embodiment includes: a base 1 and a fixed platform 2 installed on the base 1, a translation mechanism is provided on the base 1, a propulsion mechanism is provided on the translation mechanism, a frame 10 is provided on the propulsion mechanism, a first driving roller 12 is rotatably installed in the frame 10, a third motor 11 for driving the first driving roller 12 is provided on one side of the frame 10, the output shaft of the third motor 11 is fixedly connected to the shaft rod at one end of the first driving roller 12, and two support frames 15 that can move up and down are provided in the frame 10. , the second driving rollers 17 are rotatably installed on the two support frames 15, and the first driving roller 12 and the two second driving rollers 17 are sleeved with grinding belts 18. The first driving roller 12 and the two second driving rollers 17 are provided with teeth and grooves, and the inner side of the grinding belt 18 is also provided with teeth and grooves, so that the first driving roller 12, the second driving roller 17 and the grinding belt 18 form a synchronous wheel and synchronous belt structure, so as to ensure that the first driving roller 12 will not slip when driving the grinding belt 18 to rotate, so that when the mold steel hits the grinding belt 18, it will not cause the grinding belt 18 to be unable to rotate.

[0023] A tightening screw rod 3 is threadedly mounted on the fixing platform 2 , and a rotating disk is fixedly mounted on the top end of the tightening screw rod 3 .

[0024] Through the above technical scheme, the fixing table 2 has a tightening and limiting effect through the tightening screw 3, so that it can be used to limit mold steels of different thicknesses. A tightening plate is also provided at the bottom end of the tightening screw 3 to increase its contact area with the mold steel, thereby improving the tightening effect.

[0025] The translation mechanism includes a first base frame 4 fixedly mounted on the base 1 and a first screw rod 6 rotatably mounted on the first base frame 4. A first motor 5 for driving the first screw rod 6 is fixedly mounted on one side of the first base frame 4. The output shaft of the first motor 5 is fixedly connected to one end of the first screw rod 6. A first driving block is threadedly sleeved on the first screw rod 6. Two first sliding rods penetrating the first driving block are fixedly mounted on the first base frame 4.

[0026] Through the above technical solution, the translation mechanism can mobilize the grinding mechanism to translate, so that the grinding mechanism can automatically complete the trimming work of the mold steel.

[0027] The propulsion mechanism includes a second base frame 7 fixedly mounted on the first driving block, a second screw rod 9 is rotatably mounted on the second base frame 7, a second driving block is threadedly sleeved on the second screw rod 9, a second motor 8 for driving the second screw rod 9 is fixedly mounted on one side of the second base frame 7, an output shaft of the second motor 8 is fixedly connected to one end of the second screw rod 9, two second sliding rods penetrating the second driving block are fixedly mounted on the second base frame 7, and the bottom of the frame 10 is fixedly connected to the second driving block.

[0028] Through the above technical solution, the propulsion mechanism can drive the grinding mechanism forward or backward, so that the grinding belt 18 can contact the mold steel as needed, and thereby tighten the concave deformation.

[0029] The top inner wall and the bottom inner wall of the frame 10 are fixedly mounted with a positioning rod 13 that passes through the support frame 15. A cover 14 is provided at one end of the positioning rod 13. A spring 16 is sleeved on the positioning rod 13. The two ends of the spring 16 respectively abut against the support frame 15 and the cover 14.

[0030] Through the above technical solution, the frame 10 can be moved and reset, so that when the grinding belt 18 is pressed against the concave deformation, the two second driving rollers 17 can adaptably adjust their positions, and the concave of the grinding belt 18 enables it to better adapt to the mold steel, thereby realizing multi-angle grinding of the mold steel without the need for adjustment.

[0031] Two limit sliding openings 19 are arranged on the side plates at both sides of the frame 10 , and shaft sleeves 20 are rotatably sleeved on the shafts at both ends of the two second driving rollers 17 , and the four shaft sleeves 20 are respectively located in the four limit sliding openings 19 .

[0032] Through the above technical solution, the limiting sliding opening 19 cooperates with the shaft sleeve 20 to improve the stability of the frame 10 without affecting the rotation and movement of the second driving roller 17.

[0033] The side plates on both sides of the frame 10 are provided with notches.

[0034] Through the above technical solution, when the mold steel squeezes the grinding belt 18 to a concave deformation, the notch prevents the frame 10 from restricting the mold steel, ensuring that the mold steel can smoothly allow the grinding belt 18 to undergo an adaptive concave deformation.

[0035] The implementation principle of a multi-angle trimming and grinding device suitable for die steel production in the embodiment of the present application is:

[0036] Step 1: When the mold steel plate is trimmed and polished, the mold steel plate is placed on the fixed table 2 and then tightened by the tightening screw 3. Subsequently, the second motor 8 is started, and the frame 10 is driven forward by the second screw 9 until the polishing belt 18 contacts the mold steel plate and is squeezed by the mold steel plate to be concavely deformed;

[0037] Step 2: During this process, the two second driving rollers 17 will squeeze the spring 16 through the support frame 15, so that the two second driving rollers 17 are close to each other, so as to adapt to the concave deformation of the grinding belt 18. At this time, the grinding belt 18 close to the edge of the mold steel plate can not only grind the side of the mold steel plate, but also grind the upper edge corner line and the lower edge corner line of the side;

[0038] The third step: start the third motor 11 and the first motor 5 to start the translation mechanism and the grinding mechanism. The third motor 11 drives the grinding belt 18 to rotate through the first driving roller 12, and the first motor 5 drives the entire grinding mechanism to translate through the first screw 6, so as to complete the automatic grinding of the mold steel plate, and can grind the upper and lower edges and corners of the mold steel and the side surfaces simultaneously, thereby improving the trimming efficiency of the mold steel.

[0039] The above-mentioned implementation modes are only preferred implementation modes of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by technicians in this field on the basis of the present invention shall fall within the scope of protection required by the present invention.
