Description

Technical Field

[0001] The present invention relates to the technical field of finish machining, and particularly relates to a surface finish machining device for die steel. Background Art

[0002] Die steel is a special type of steel specifically used for manufacturing dies. It mostly has a rectangular structure and has characteristics such as high hardness, high strength, excellent wear resistance, and fatigue strength, and is suitable for manufacturing dies that require relatively high precision and wear resistance. In order to improve the surface hardness and wear resistance of die steel and extend the service life of the die, finish grinding is performed on die steel to remove burrs, oxide layers, sintered layers, and other uneven surface defects on its surface.

[0003] The commonly used finish grinding method for die steel is to first manually fix the die steel on the workbench of the grinding machine through a limiting member, and then the grinding wheel of the grinding machine rotates and feeds to perform finish grinding on the upper end surface of the die steel. After the end surface of the die steel is polished, the die steel is loosened and the end surface is rotated and then fixed again for grinding. In this way, the finish grinding of the six end surfaces of the die steel is achieved. However, the complexity of the entire operation of manually fixing and disassembling the die steel multiple times and rotating the direction to grind different end surfaces is relatively high, reducing the production efficiency. Moreover, each time the die steel is manually fixed, there will be certain differences in the fixed position and fixing force of the die steel, which affects the quality of the finish grinding of the die steel and further affects the accuracy of the manufactured die.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, the execution part 28 includes a guide groove 280, and the opposite surfaces of the two front and rear opposite fixed plates 22 are provided with a guide groove 280, and the guide groove 280 is an inverted U-shaped structure, and the front and rear end surfaces of the vertical section of the L-shaped plate 23 are installed with two rollers 281 that slide with the corresponding guide grooves 280, and the fixed frame 12 is provided with a lifting member 282 for lifting the L-shaped plate 23.

[0037] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the lifting member 282 includes a waist-shaped groove, and the two vertical sections of the fixed frame 12 are both provided with a waist-shaped groove. An axle rod 2820 is slidably installed in the two waist-shaped grooves.

[0039] During specific operation, the external feeding mechanism places the mold steel to be polished on the upper end surface of the vacuum suction cup 41, and then the external air pump is connected to the vacuum suction cup 41 through the external delivery pipe, and the external delivery pipe is provided with an external solenoid valve. After the external solenoid valve is opened, the external air pump causes the vacuum suction cup 41 to adsorb and fix the mold steel through the external delivery pipe, and then the external hydraulic cylinder installed in the vertical section of the fixed frame 12 pushes the shaft rod 2820 to move downward, and the shaft rod 2820 pushes the L-shaped plate 23 to move downward through the push-pull rod 2824 until the left and right extrusion blocks 25 are located in the middle position of the corresponding side end surface of the mold steel. At the same time, the arc-shaped inner wall of the upper part of the waist groove 272 fits with the fixed column 273 to further limit the downward movement of the L-shaped plate 23, thereby further improving the stability of the extrusion block 25. Then, the external No. 1 motor installed on the fixed frame 12 drives the bidirectional screw 20 to rotate, and the bidirectional screw 20 drives the corresponding two L-shaped plates 23 to approach each other through the two No. 2 screw blocks 21 and the corresponding fixed plates 22. The L-shaped plate 23 extrude and fix the mold steel through the extrusion block 25 to further improve the stability of the mold steel in the subsequent grinding process. Then the grinding mechanism 3 grinds the upper end surface of the mold steel.

[0040] like Figure 1 , Figure 2 , Figure 3 and Figure 7 As shown, the grinding mechanism 3 includes a screw rod 30, and the screw rod 30 is rotatably installed on the rear side of the fixed frame 12 through an axis plate, and a No. 1 screw block 31 is threadedly connected to the screw rod 30 and is slidably connected to the fixed frame 12. A support plate 32 is installed on the rear end face of the No. 1 screw block 31, and the support plate 32 is an inverted structure, and a reinforcing rib is arranged between the support plate 32 and the No. 1 screw block 31, and the screw rod 30 rotates and penetrates the reinforcing rib, and a slide plate 33 is slidably installed between the two vertical sections of the support plate 32, and a push-pull assembly for adjusting the upper and lower positions of the slide plate 33 is arranged at the upper end of the support plate 32, and a shaft column 34 is rotatably installed on the slide plate 33, and a grinding roller 35 is hingedly connected to the rear end of the shaft column 34 after penetrating the slide plate 33, and a rotating part 37 for driving the shaft column 34 to rotate and driving the grinding roller 35 to deflect on the shaft column 34 is arranged on the slide plate 33.

[0041] like Figure 1 , Figure 2 and Figure 7As shown, the rotating part 37 includes a stepper motor 370, and the stepper motor 370 is installed on the rear end face of the slide plate 33 through a motor seat. The output shaft of the stepper motor 370 is connected to the shaft column 34 through a bevel gear set. The front end face of the slide plate 33 is rotatably installed with a vertical rotating shaft 371 through the shaft seat. A support rod 372 is fixedly installed on the rotating shaft 371, and the other end of the support rod 372 is hinged with a shaft block 373, and the shaft block 373 is rotatably connected to the front end of the grinding roller 35, and the axis of the rotating shaft 371 is colinear with the hinge axis of the grinding roller 35.

[0042] like Figure 3 and Figure 7 As shown, the push-pull assembly includes an electric telescopic rod 36 , and the electric telescopic rod 36 is installed on the upper end surface of the support plate 32 . The telescopic end of the electric telescopic rod 36 slides through the support plate 32 and is fixedly connected to the slide plate 33 .

[0043] During specific operation, first, the external No. 2 motor installed on the slide plate 33 drives the rotating shaft 371 to rotate, and the rotating shaft 371 drives the grinding roller 35 to rotate from the horizontal state to the longitudinal state through the support rod 372, that is, from the left and right extension state to the front and back extension state, and the external No. 3 motor installed on the fixed frame 12 drives the screw rod 30 to rotate, and the screw rod 30 drives the grinding roller 35 to move to the right away from the mold steel through the No. 1 screw block 31, the support plate 32, and the slide plate 33, and then the electric telescopic rod 36 pushes the slide plate 33 to move downward, and the slide plate 33 drives the grinding roller 35 to move downward to the position corresponding to the required grinding amount of the mold steel, and then the stepper motor 370 drives the shaft column 34 to rotate through the bevel gear set, and the shaft column 34 drives the grinding roller 35 to rotate, and then the external No. 3 motor drives the grinding roller 35 horizontally through the No. 1 screw block 31, the support plate 32, and the slide plate 33. The electric telescopic rod 36 drives the grinding roller 35 to move upward through the slide plate 33 to move away from the rotation range of the mold steel. Then, the vacuum suction cup 41 is released from the adsorption of the mold steel, and the vacuum suction cup 41 is driven away from the mold steel through the electric lifting platform 40. Then, the servo motor 26 drives the disc 24 and the extrusion block 25 to rotate and drives the extruded mold steel to rotate ninety degrees. After the rotation is completed, the electric lifting platform 40 pushes the vacuum suction cup 41 to fit the mold steel, and adsorbs and fixes the mold steel through the vacuum suction cup 41. Then, the electric telescopic rod 36 drives the grinding roller 35 to move downward to the grinding height through the slide plate 33 to grind the side end surface of the mold steel. Subsequently, the mold steel is rotated according to the above operation, and the four surfaces of the mold steel in the length direction are grinded in turn.

[0044] Secondly, after the grinding processing of the four surfaces in the length direction of the mold steel is completed, the electric telescopic rod 36 drives the grinding roller 35 away from the mold steel through the slide plate 33, and then the screw rod 30 drives the grinding roller 35 to move to the left. When the grinding roller 35 moves to the middle of the mold steel, the external No. 2 motor drives the grinding roller 35 to rotate ninety degrees clockwise through the rotating shaft 371 and the support rod 372. At this time, the grinding roller 35 rotates from the longitudinal state to the transverse state, and then the external No. 1 motor drives the two No. 2 screw blocks 21 away from each other through the bidirectional screw 20, so that the extrusion block 25 is away from the mold steel, and the L-shaped plate 23 compresses the corresponding return spring 2822 through the push-pull rod 2824 and the sleeve 2823, and then the external hydraulic cylinder pushes the slider to move upward, and the slider drives the shaft rod 2820 to move upward, and the shaft rod 2820 pulls the L-shaped plate 23 upward through the push-pull rod 2824. The upward movement of the L-shaped plate 23 will make the arc-shaped inner wall of the upper end of the waist groove 272 away from the fixed Column 273, and at the same time, the roller 281 located on the upper part of the L-shaped plate 23 will first move from the vertical section of the guide groove 280 to its arc section, so that under the guidance of the arc section of the guide groove 280 and the resilience of the return spring 2822, the push-pull rod 2824 pushes the L-shaped plate 23, so that the roller 281 located on the upper part moves through the arc section of the guide groove 280 to the vertical section on the other side, and then the two rollers 281 opposite to each other are respectively located in the two vertical sections of the guide groove 280, and the L-shaped plate 23 will rotate ninety degrees, and the support plate 271 will rotate from a vertical state to a horizontal state, and then the external No. 1 motor drives the bidirectional screw 20 to rotate, so that the two No. 2 screw blocks 21 approach each other and drive the extrusion block 25 to be located directly above the mold steel. At this time, the limiting column 2750 and the corresponding limiting hole 2751 are plugged and matched to keep the support plate 271 in a horizontal state, thereby ensuring the stability of the extrusion block 25 after rotation.

[0045] After that, the external hydraulic cylinder pulls the shaft 2820 downward through the slider, and the shaft 2820 pushes the L-shaped plate 23 downward through the push-pull rod 2824. The L-shaped plate 23 squeezes and fixes the mold steel from top to bottom through the extrusion block 25, and then the screw 30 drives the grinding roller 35 to move to the left side of the mold steel, and then the external No. 2 motor drives the grinding roller 35 to rotate 90 degrees counterclockwise to rotate from the horizontal state to the vertical state, and then the electric telescopic rod 36 pushes the slide plate 33 to move downward, and the slide plate 33 The rotating grinding roller 35 is driven to move from top to bottom and grind the left end face of the mold steel. After the left end face of the mold steel (i.e., the side end face in the width direction of the mold steel) is ground, the grinding roller 35 moves up and away from the mold steel. Then, the external No. 2 motor drives the grinding roller 35 to rotate ninety degrees clockwise. Then, the external No. 3 motor drives the screw rod 30 to rotate, so that the grinding roller 35 moves to the right. When the grinding roller 35 moves to the right side of the mold steel, the external No. 2 motor drives the grinding roller 35 to rotate one hundred and eighty degrees counterclockwise. Then the electric telescopic rod 36 pushes the slide plate 33 to move downward, and the slide plate 33 drives the rotating grinding roller 35 to move from top to bottom and grind the right end surface of the mold steel. After the grinding is completed, the grinding roller 35 and the extrusion block 25 are away from the mold steel, and the polished mold steel is taken out. Then the bidirectional screw 20 drives the corresponding L-shaped plates 23 to approach each other through the two No. 2 screw blocks 21, and stretches the corresponding return spring 2822. The external hydraulic cylinder pushes the slider to move upward, and the slider drives the shaft 2820 upward. The shaft 2820 pulls the L-shaped plate 23 upwards through the push-pull rod 2824, so that the roller 281 moves to the arc section position of the guide groove 280, and then the push-pull rod 2824 pulls and guides the L-shaped plate 23 under the action of the rebound force of the reset spring 2822, and the deflection of the center of gravity of the L-shaped plate 23 causes the L-shaped plate 23 to rotate and reset, and then the external feeding mechanism places the mold steel to be polished on the vacuum suction cup again and repeats the above operation to carry out continuous production and polishing of the mold steel.
