Description

Technical Field

[0001] The invention relates to the technical field of cemented carbide tool grinding and forming, in particular to a cemented carbide tool forming and grinding device. Background Art

[0002] Carbide cutting tools are high-performance cutting tools. Due to their high hardness, high wear resistance and good heat resistance, they are widely used in metal processing, wood processing, stone processing and other fields. Among them, triangular alloy blades are common carbide cutting tools, which are generally used for milling of metal workpieces, such as plane milling, slot milling and contour milling of metal workpieces. In the prior art, triangular alloy blades are usually provided with through grooves for positioning and installation. When grinding one of the sharp corners on the end of the triangular alloy blade, it is generally first positioned and installed on the swing device through the positioning through groove on the triangular alloy blade, and then the triangular alloy blade is clamped and fixed by the clamping plate by manually tightening the bolts, and finally the grinding wheel is fit with the end sharp corner of the triangular alloy blade for grinding, and the end sharp corner of the triangular alloy blade is fit with the grinding wheel through the swing device while constantly swinging back and forth at a fixed angle until the end sharp corner of the triangular alloy blade is polished smooth and flat.

[0003] However, the traditional method of grinding the sharp corners of the end of the hard triangular alloy blade has the following problems: 1. In the prior art, a single grinding wheel usually only grinds the end of a single triangular alloy blade. This processing method results in low overall grinding efficiency and grinding wheel utilization efficiency, and there is a large waste of space resources in the processing operation, which in turn leads to a high overall processing cost of the triangular alloy blade; 2.

A swivel seat 415 is fixedly provided on the rear side of the sliding frame 412 between the upper baffle plate 413 and the lower baffle plate 414. Rotating shafts 416 are symmetrically fixedly provided at the left and right ends of the swivel seat 415. A swivel plate 417 is rotatably provided on the rear side of the swivel seat 415 through a support 1 rotatably connected to the rotating shaft 416. The swivel plate 417 is located between the upper baffle plate 413 and the lower baffle plate 414. An L-shaped support plate 418 is fixedly provided at the rear end of the swivel plate 417. The horizontal section of the L-shaped support plate 418 is slidably matched with the positioning column 1 327 and the positioning column 2 328.

[0039] When the sliding frame 412 moves upward from the lowest point along the guide rod 411, the rotating seat 415 drives the rotating plate 417 and the L-shaped support plate 418 to move upward synchronously through the rotating shaft 416. When the horizontal section of the L-shaped support plate 418 is separated from the positioning column 1 327 and the positioning column 2 328, and the vertical section of the L-shaped support plate 418 is not perpendicular to the rear surface of the limit seat 326, under the action of gravity, the rotating plate 417 drives the L-shaped support plate 418 to rotate downward around the rotating shaft 416 until the sliding frame 412 moves to the highest point. At this time, the rotating plate 417 just drives the L-shaped support plate 418 to rotate downward to the maximum angle, and at this time, the rotating plate 417 just stably fits with the upper surface of the lower baffle 414.

[0040] See also Figure 5 and Figure 6 The positioning assembly 42 includes a clamping seat 421, an elastic clamping groove 422 and a clamping column 423; the upper side of the support platform 325 is symmetrically fixed with a clamping seat 421 on the left and right sides of the rotating seat 415, and the upper ends of the clamping seats 421 are each provided with an elastic clamping groove 422, and the ends of the left and right symmetrical rotating shafts 416 away from the rotating seat 415 are fixedly provided with clamping columns 423 that are clamped with the corresponding elastic clamping grooves 422.

[0041] When the sliding frame 412 moves downward from the highest point along the guide rod 411, the rotating seat 415 drives the rotating plate 417 and the L-shaped supporting plate 418 to move downward synchronously through the rotating shaft 416, and the vertical section of the L-shaped supporting plate 418 first contacts the rear surface of the limiting seat 326 and gradually begins to fit. When the vertical section of the L-shaped supporting plate 418 is completely fitted with the rear surface of the limiting seat 326 and is in a vertical state, the horizontal section of the L-shaped supporting plate 418 begins to slide on the positioning column 1 327 and the positioning column 2 328 until the sliding frame 412 moves to the lowest point. At this time, the horizontal section of the L-shaped supporting plate 418 is stably fitted with the upper surface of the limiting seat 326, and the rotating shaft 416 synchronously drives the corresponding clamping column 423 to move downward to the lowest point. At this time, the clamping column 423 is just elastically clamped and positioned with the elastic clamping groove 422 on the corresponding clamping seat 421.

[0042] See also Figure 4 and Figure 8 The docking assembly 43 includes a docking column 431, a sliding column 432, an unlocking ring 433, a docking joint 434 and a receiving groove 435; a docking column 431 with a truncated cone at the upper end is fixedly provided on the upper side of the upper baffle 413, a sliding column 432 is fixedly provided on the upper end of the docking column 431, an unlocking ring 433 is slidably provided on the surface of the sliding column 432, the outer edge of the unlocking ring 433 is a symmetrical inclined surface, a docking joint 434 with an arc surface at the upper end is fixedly provided on the upper end of the sliding column 432, and a receiving groove 435 for receiving the unlocking ring 433 is provided at the connection between the docking joint 434 and the sliding column 432.

[0043] See also Figure 5 , Figure 7 and Figure 8 The clamping assembly 44 includes a clamping plate 441, a sleeve 442, a spring seat 443 and a telescopic clamp 444; a clamping plate 441 is slidably arranged on the guide rod 411 above the sliding frame 412, and a sleeve 442 that slidably cooperates with the docking head 434 and the docking column 431 is fixedly arranged on the lower side of the clamping plate 441 through a rod, and a spring seat 443 is fixedly arranged on the front side of the sleeve 442, and a telescopic clamp 444 with a sloped rear end is elastically slidably arranged in the spring seat 443.

[0044] When the inclined surface at the rear end of the telescopic clamp 444 fits with the inclined surface on the upper side of the outer edge of the unlocking ring 433, the clamping plate 441 drives the sleeve 442 to move upward along the guide rod 411, and the rear end of the telescopic clamp 444 disengages from the unlocking ring 433 and moves upward along the sliding column 432 until the rear end of the telescopic clamp 444 contacts and fits with the lower surface of the docking joint 434. As the clamping plate 441 continues to move upward to the uppermost end of the guide rod 411, the telescopic clamp 444 drives the docking joint 434 and the sliding column 432 to move upward synchronously, and the sliding column 432 drives the upper baffle 413 and the sliding frame 412 to move from the lowest point to the highest point along the guide rod 411 through the docking column 431.

[0045] When the retractable card member 444 drives the docking head 434 and the sliding frame 412 to move to the highest point, the clamping plate 441 drives the retractable card member 444 to move downward along the guide rod 411, and the docking head 434 moves downward synchronously therewith. When the docking head 434 and the sliding frame 412 move downward to the lowest point, the clamping plate 441 can continue to drive the retractable card member 444 to move downward along the sliding post 432 until the inclined surface at the rear end of the retractable card member 444 is again fitted with the inclined surface on the upper side of the outer edge of the unlocking ring 433. As the clamping plate 441 continues to move downward, and at the same time, under the action of the inclined surface on the upper side of the outer edge of the unlocking ring 433, the retractable card member 444 first contracts into the spring seat 443 until the rear end of the retractable card member 444 is separated from the unlocking ring 433, and under the action of the spring seat 443, the rear end of the retractable card member 444 extends out again and fits with the inclined surface on the upper end of the docking post 431.

[0046] When the rear end of telescopic card member 444 is in contact with the inclined surface on the upper end of docking column 431, the clamping plate 441 drives the telescopic card member 444 to move upward along the guide rod 411, and the rear end of telescopic card member 444 presses the inclined surface on the lower side of the outer edge of unlocking ring 433, thereby driving the unlocking ring 433 to move upward synchronously along the sliding column 432 until the upper half of the unlocking ring 433 is completely received in the receiving groove 435 and cannot move further upward. At this time, the rear end of telescopic card member 444 is first retracted into the spring seat 443 under the action of the inclined surface on the lower side of the outer edge of the unlocking ring 433. , until the rear end of the telescopic card 444 disengages from the unlocking ring 433 and contacts the arc surface on the docking joint 434, at which time the unlocking ring 433 slides downward again to the lower end of the sliding column 432 under the action of gravity, and as the clamping plate 441 continues to move up to the highest point, the rear end of the telescopic card 444 is unlocked and completely disengaged from the docking joint 434, wherein the docking joint 434 and the sliding frame 412 are stably positioned by the engagement of the clamping column 423 and the clamping seat 421, thereby ensuring that the telescopic card 444 can be stably unlocked and disengaged from the docking joint 434.

[0047] When the inclined surface at the rear end of the telescopic card 444 is to be driven to fit the inclined surface on the upper side of the outer edge of the unlocking ring 433 again, the clamping plate 441 drives the telescopic card 444 to move downward along the guide rod 411 again, and the inclined surface at the rear end of the telescopic card 444 then cooperates with the arc surface on the docking joint 434, so that the telescopic card 444 first contracts into the spring seat 443 until the rear end of the telescopic card 444 is completely separated from the docking joint 434. At this time, under the action of the spring seat 443, the telescopic card 444 extends backward again, and as the clamping plate 441 continues to move downward, the inclined surface at the rear end of the telescopic card 444 can fit the inclined surface on the upper side of the outer edge of the unlocking ring 433 again.

[0052] When the clamping plate 441 is to be moved upward along the guide rod 411, the pneumatic cylinder 532 drives the pressing plate 533 to move upward. Under the upward elastic force of the spring rod 521, the sliding plate 522 moves upward along the spring rod 521 to reset, and the swing rod 524 synchronously drives the corresponding clamping plate 441 to move upward along the guide rod 411.

[0053] When multiple triangular alloy blades are to be sharpened simultaneously (such as Fig. 9 As shown in the figure), first align the positioning grooves on each triangular alloy blade (such as Fig.10The first and second positioning columns 327 and 328 on the corresponding limit seats 326 are aligned and inserted for positioning, and then all the clamping plates 441 are driven by the pneumatic cylinder 532 to move downward along the corresponding guide rods 411 until the corresponding triangular alloy blades are clamped and fixed, so that each triangular alloy blade is evenly installed and positioned on the front side of the grinding wheel 25. At this time, the inclined surfaces at the rear ends of each telescopic clamp 444 are in contact with the inclined surfaces on the upper sides of the outer edges of the corresponding unlocking rings 433. Then, the L-shaped moving frame 23 is driven by the electric slider 22 to move forward along the guide rail 21, and the motor 24 and the grinding wheel 25 move forward synchronously therewith until the ends of each triangular alloy blade are in contact with the corresponding positions on the front surface of the grinding wheel 25. At this time, the grinding wheel 25 is driven by the motor 24 to rotate, so that the ends of all the triangular alloy blades are synchronously moved. During grinding, all the limit seats 326 are driven by the electric push rod 312 to swing back and forth synchronously at a fixed angle around the corresponding connecting shaft 321, so that the ends of the corresponding triangular alloy blades on all the limit seats 326 are in contact with the grinding surface of the grinding wheel 25 and swing back and forth at a fixed angle continuously until the ends of all the triangular alloy blades are polished smooth and flat, wherein the arc groove 523 on the sliding plate 522 enables the swing rod 524 to swing back and forth synchronously with the corresponding clamping plate 441. This grinding method can synchronously swing and grind the ends of all installed and positioned triangular alloy blades, thereby greatly improving the overall grinding efficiency of the triangular alloy blades and the utilization efficiency of the grinding wheel 25, and to a certain extent avoiding the waste of space resources, thereby reducing the overall processing cost of the triangular alloy blades.

[0054] When all the triangular alloy blades are polished, the grinding wheel 25 is first driven backward by the electric slider 22, and then a container capable of holding all the triangular alloy blades is placed under the triangular alloy blades. A cushion for buffering can be arranged in the container, and then the clamping plate 441 is moved upward along the guide rod 411 to the highest point, and the telescopic clamp 444 drives the docking head 434 and the sliding frame 412 to move upward to the highest point, and the rotating plate 417 drives the L-shaped support plate 418 to rotate downward to the maximum angle. At this time, all the triangular alloy blades slide down synchronously along the horizontal section of the corresponding L-shaped support plate 418 under the action of gravity. The material falls into the receiving container. Since the triangular alloy blades are evenly distributed on the front side of the grinding wheel 25, the triangular alloy blades are staggered to drop the material. This avoids the triangular alloy blades colliding with each other and falling out of the receiving container during the falling process. This operation method can quickly and stably clamp and fix all the triangular alloy blades positioned on the limit seat 326 synchronously. At the same time, after grinding is completed, all the triangular alloy blades can be quickly and synchronously released and automatically and stably discharged, thereby greatly simplifying the operation of clamping and taking out the triangular alloy blades, reducing the manual operation burden, and improving the overall operation efficiency.

[0055] When the triangular alloy blade is to be positioned and placed on the limit seat 326 again, the docking head 434 and the sliding frame 412 are first moved downward synchronously with the clamping plate 441 and the telescopic clamping piece 444 until the clamping column 423 is clamped and positioned with the corresponding clamping seat 421, and then the clamping plate 441 continues to drive the telescopic clamping piece 444 to move downward until the inclined surface at the rear end of the telescopic clamping piece 444 is in contact with the inclined surface at the upper end of the docking column 431, and then the telescopic clamping piece 444 is moved upward and pressed together with the unlocking ring 433, so that the telescopic clamping piece 444 and the docking head 434 are unlocked and disengaged and continue to move to the highest point, at this time, the triangular alloy blade to be polished can be positioned and placed on the corresponding limit seat 326, and finally all the clamping plates 441 are driven downward by the pneumatic cylinder 532 until the corresponding triangular alloy blade is clamped and fixed, and at this time, the inclined surface at the rear end of the telescopic clamping piece 444 is also in contact with the inclined surface on the upper side of the outer edge of the unlocking ring 433 again.
