Description

Technical Field

[0001] The invention relates to the technical field of cemented carbide processing, in particular to a cemented carbide workpiece production stacking mechanism. Background Art

[0002] Cemented carbide is an alloy material made from hard compounds of refractory metals and bonding metals through powder metallurgy. It has high hardness, strength, wear resistance and corrosion resistance. It is known as the "teeth of industry" and is used to manufacture cutting tools, knives, cobalt tools and wear-resistant parts. It is widely used in military industry, aerospace, mechanical processing, metallurgy, oil drilling, mining tools, electronic communications, construction and other fields.

[0003] The Chinese invention patent with the announcement number CN114701866B discloses a stacking mechanism for the production of cemented carbide workpieces, including: a stacking rack and a feeding mechanism, the stacking rack is used to place blank plates, the feeding mechanism is used to feed the blank plates to the stacking rack, the stacking rack has multiple storage cavities, the stacking rack is movably arranged at the outlet end of the feeding mechanism; the outlet end of the feeding mechanism is connected to a positioning adjustment mechanism, the positioning adjustment mechanism is used to synchronously drive the stacking rack to slide and adjust to switch the storage cavity and the feeding mechanism to align and receive materials. The invention realizes passive synchronous driving of each storage cavity on the stacking rack to align and receive materials with the feeding mechanism in turn, that is, it can maintain passive synchronous adjustment with the conveying speed of the feeding mechanism, and does not require staff to monitor the conveying speed of the feeding mechanism for control and adjustment, so as to realize fully automatic stacking of blank plates and significantly improve the stability of the stacking operation.

[0004] However, the above patent still has the following shortcomings in actual use: 1. The patent arranges the blank plates at equal intervals on the conveyor belt for transportation. The equal interval arrangement of the blank plates cannot be achieved automatically and requires the assistance of workers. The accuracy of manual arrangement of the blank plates is also poor; 2. When the blank plates move to the tail end of the conveyor belt, the head end of the blank plates will gradually enter the storage cavity. Once the blank plates are separated from the conveying surface of the conveyor belt, they lose the conveying and moving force. Since there is a certain gap between the tail end of the conveyor belt and the partition, the blank plates cannot be completely entered into the storage cavity, that is, a part of the blank plates is in a suspended state, and the blank plates are very easy to fall from the partition. The elastic driving part of the patent cannot drive the blank plates to move into the storage cavity, and even jamming may occur. The blank plates are very easy to be damaged, affecting the processing quality. Summary of the invention

Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figure 1-8 , the above technical solutions of the present invention are described in detail through the following embodiments:

[0033] A stacking mechanism for producing cemented carbide workpieces includes a stacking rack 1, a conveyor belt 2 for conveying blank plates 10, a guide rail rack 3, a rack locking member 4 for locking the stacking rack 1, and a positioning adjustment mechanism 5 for driving the stacking rack 1 to lift and lower. Two symmetrically arranged conveying roller shafts 21 are installed on the conveyor belt 2. The guide rail rack 3 is arranged adjacent to the conveyor belt 2. The stacking rack 1 and the rack locking member 4 are both arranged on the guide rail rack 3. The positioning adjustment mechanism 5 is arranged on the conveyor belt 2. The stacking rack 1 is successively provided with a plurality of equally spaced bearing plates 11 from bottom to top. An angle adjustment mechanism 6 for adjusting the placement angles of all the bearing plates 11 is provided on the stacking rack 1. An auxiliary roller shaft 22 is rotatably arranged in the middle of the conveyor belt 2. One end of the auxiliary roller shaft 22 is provided with a first sprocket 221. One end of one of the conveying roller shafts 21 is provided with a second sprocket. The first sprocket 221 and the second sprocket are connected by a chain drive. Two symmetrically arranged baffles 23 are provided at the top of the conveyor belt 2. A limiting conveying interval 24 is formed between the two baffles 23. The head end of the baffle 23 is provided with a centrally guiding plate 25 arranged obliquely. A material blocking mechanism 7 for spacing the blank plates 10 in the limiting conveying interval 24 is provided in the middle of the conveyor belt 2. The material blocking mechanism 7 is in transmission connection with the auxiliary roller shaft 22. A pushing mechanism 8 for assisting in pushing the blank plates 10 between the two centrally guiding plates 25 is provided on one side of the conveyor belt 2. A guiding mechanism 9 for guiding the blank plates 10 onto the bearing plates 11 is provided at the tail end of the conveyor belt 2.

[0034] The present invention can automatically guide the blank plates 10 on the conveyor belt 2 into the limiting conveying interval 24 through the two centrally guiding plates 25, and can space the blank plates 10 in the limiting conveying interval 24 through the material blocking mechanism 7, thereby realizing the automatic equal-spacing arrangement of the blank plates 10 on the conveyor belt 2. The placement angles of all the bearing plates 11 can be adjusted through the angle adjustment mechanism 6, and the blank plates 10 can be guided onto the bearing plates 11 through the guiding mechanism 9. After adjusting the bearing plates 11 to an inclined state, the blank plates 10 can move by their own gravity, so that the blank plates 10 can completely enter the storage cavity, improving the processing quality.

[0035] It should be noted that the rack locking member 4 and the alignment adjustment mechanism 5 of the present invention are both prior arts and will not be elaborated herein.

[0036] When the present invention is working, first, the placement angle of the bearing plate 11 is adjusted by the angle adjustment mechanism 6. The angle adjustment mechanism 6 includes an adjustment rod 61 and a plurality of worm wheels 62. A plurality of worm gears 611 are installed on the adjustment rod 61. First rotating shafts 111 are provided on both sides of the bearing plate 11. A detachable rotating handle 63 is provided at the top of the adjustment rod 61. Two first rotating seats 12 arranged symmetrically up and down are provided on the side wall of the stacking rack 1. The bearing plate 11 is rotatably arranged on the stacking rack 1 through the first rotating shaft 111. The adjustment rod 61 is rotatably arranged on the two first rotating seats 12. All the worm wheels 62 are respectively fixed on all the first rotating shafts 111 on the same side of all the bearing plates 11. All the worm wheels 62 are respectively engaged with all the worm gears 611.

[0037] The rotation of the adjustment rod 61 can be driven by the rotating handle 63. The adjustment rod 61 drives all the worm gears 611 to rotate synchronously. The worm gears 611 drive the worm wheels 62 to rotate. The worm wheels 62 drive the first rotating shafts 111 to rotate synchronously. The first rotating shafts 111 can drive the bearing plate 11 to become inclined. The blank plate member 10 can still continue to slide and move by its own gravity on the inclined bearing plate 11.

[0038] Of course, the rotating handle 63 can also be replaced by a motor for driving.

[0039] After that, the blank plate member 10 is placed on the conveyor belt 2. The conveyor belt 2 is started. Then the two conveyor rollers 21 also rotate synchronously. One of the conveyor rollers 21 drives the auxiliary roller 22 to rotate synchronously through a second sprocket, a chain and a first sprocket 221. The blank plate member 10 is conveyed and moves towards the centering guide plate 25. The centering guide plate 25 guides the blank plate member 10 into the limit conveying section 24. The pushing mechanism 8 can prevent the blank plate member 10 from getting stuck at the inlet of the limit conveying section 24.

[0040] A push window 251 is provided at the bottom of one of the centered guide plates 25. The push mechanism 8 includes a push plate 81 and a second rotating seat 82 matching the push window 251. A cross bar 83 is provided on the back of the push plate 81. An L-shaped plate 84 is provided on the top of the cross bar 83. A second interference rod 85 is provided at the end of the L-shaped plate 84. A second rotating shaft 86 is rotatably provided on the second rotating seat 82. A mounting ring 87 and a third sprocket 89 are provided on the second rotating shaft 86. A toggle rod 88 is provided on the mounting ring 87. The toggle rod 88 is provided with a first arc surface 881 matching the second interference rod 85. Two symmetrically arranged mounting seats 27 are provided on the top of the conveyor belt 2. A guide rod 271 is provided between the two mounting seats 27. A second spring 272 is sleeved on the guide rod 271. A guide hole matching the guide rod 271 is also provided on the L-shaped plate 84. A fourth sprocket 222 is provided at the other end of the auxiliary roller shaft 22. The fourth sprocket 222 is connected to the third sprocket 89 through a chain transmission.

[0041] After the auxiliary roller 22 rotates, it can drive the fourth sprocket 222 to rotate synchronously. The fourth sprocket 222 drives the third sprocket 89 to rotate through the chain. The third sprocket 89 drives the second rotating shaft 86 to rotate. The second rotating shaft 86 drives the mounting ring 87 to rotate. The mounting ring 87 drives the toggle rod 88 to rotate synchronously around the axis of the second rotating shaft 86. The first arc surface 881 on the toggle rod 88 can gradually abut against the second resistance rod 85. Then the toggle rod 88 drives the second resistance rod 85 to move. The second resistance rod 85 drives the L-shaped plate 84 to move backward on the guide rod 271. In order to prevent the L-shaped plate 84 from deflecting, the cross section of the guide rod 271 is set to a polygon. Then the cross bar 83 and the push plate 81 also move backward synchronously with the L-shaped plate 84 The push plate 81 moves from the state of extending out from the push window 251 to the state of being completely retracted into the push window 251, and the second spring 272 is also compressed synchronously, and then the second abutting rod 85 is disengaged from the toggle rod 88, and the elastic force of the second spring 272 drives the L-shaped plate 84 to move forward, and the push plate 81 also moves forward synchronously, and the push plate 81 extends out from the push window 251, and the cycle continues like this. The push plate 81 can assist in pushing the blank plate 10 that abuts on the centering guide plate 25, and the pushed blank plate 10 can abut against other blank plates 10 for synchronous movement, thereby changing the position of the blank plate 10 between the two centering guide plates 25, thereby avoiding the blank plate 10 from being stuck at the entrance of the limit conveying interval 24.

[0042] After the blank sheet 10 enters the limited conveying interval 24, the blank sheet 10 may also be in a stacked state. The stacked blank sheet 10 can also enter the limited conveying interval 24 simultaneously. Therefore, a height limiting plate 231 is provided between the two baffles 23. A passing groove for a blank sheet 10 to pass through is formed between the bottom of the height limiting plate 231 and the conveying surface of the conveyor belt 2. The blank sheet 10 stacked on the upper part can be blocked by the height limiting plate 231. After passing through the passing groove, the blank sheet 10 can be sorted at equal intervals by the material blocking mechanism 7.

[0043] The material blocking mechanism 7 includes a top plate 71 and two transmission members 72 for driving the top plate 71 to rise and fall. Two symmetrically arranged blocking rods 73 are provided at the middle end of the bottom of the top plate 71 and are used to block the blank plate 10 in the limited conveying interval 24. Lifting rods 74 are provided at the bottom of both ends of the top plate 71. A limiting plate 75 is provided at the bottom of the lifting rod 74. A first spring 76 is sleeved on the lower half of the lifting rod 74. Suspensions 26 are provided on both sides of the conveyor belt 2. A sliding seat 261 that slidably cooperates with the lifting rod 74 is provided on the suspension 26. Two guide seats 232 that guide and cooperate with the blocking rod 73 are provided on the back of the height limiting plate 231. The two transmission members 72 are respectively arranged on both sides of the auxiliary roller shaft 22, and the two transmission members 72 are respectively connected to the two lifting rods 74 for transmission.

[0044] The transmission member 72 includes a transmission disk 721, and an arc-shaped disk 722 integrally connected to the transmission disk 721 is provided on the outer wall thereof, a guide slope 7221 is provided on one side of the arc-shaped disk 722, and an arc-shaped slide groove 7222 is provided on the other side of the arc-shaped disk 722, an arc-shaped strip 7223 is slidably provided in the arc-shaped slide groove 7222, a locking piece capable of locking the arc-shaped strip 7223 is provided on the outer wall of the arc-shaped disk 722, and a first interference rod 741 is provided on the lifting rod 74, and the first interference rod 741 interferes with the transmission disk 721.

[0045] The first stop bar 741 is pressed against the top of the support frame 722, and the first stop bar 741 is pressed against the bottom of the support frame 722, so that the support frame 722 can be easily moved upward by the spring 76. The elastic force of a spring 76 drives the first contact rod 741 to contact the outer wall of the transmission disk 721, and the lifting rod 74 also moves downward synchronously, and then the two baffles 73 can block the next blank plate 10. The curvature of the arc disk 722 determines the residence time of the lifting rod 74 after rising. The curvature of the arc disk 722 can be changed by adjusting the arc strip 7223, so that adaptive adjustment can be made according to blank plates 10 of different sizes. The locking piece is a locking screw 723. The arc strip 7223 is provided with a plurality of screw holes 7224 distributed at equal angles and cooperating with the locking screw 723. The outer wall of the arc disk 722 is provided with a socket 7225 for inserting the locking screw 723. The adjusted arc strip 7223 can be locked by the locking screw 723. The blank plate 10 can also be automatically moved in equal spacing by orderly lifting and lowering of the two baffles 73.

[0046] After the blank plate 10 is conveyed to the tail end of the conveyor belt 2 by the conveyor belt 2, the blank plate 10 is guided to the supporting plate 11 by the guiding mechanism 9. The guiding mechanism 9 includes two lower hanging plates 91 and an auxiliary strap 92. A third rotating shaft 921 is provided on both sides of the auxiliary strap 92. The two lower hanging plates 91 are respectively fixed to the bottom of the tail ends of the two baffles 23. The auxiliary strap 92 is rotatably set on the two lower hanging plates 91 through the third rotating shaft 921. The guiding mechanism 9 also includes two shaking components 93 that can shake the auxiliary strap 92 as the stacking rack 1 moves downward. The two shaking components 93 are respectively set on the two lower hanging plates 91, and the shaking components 93 are transmission connected to the third rotating shaft 921.

[0047] The jitter component 93 includes two fixed seats 931, an arc-shaped rod 932, a jitter disk 933, and several L-shaped abutting rods 934. A third spring 935 is sleeved on the arc-shaped rod 932. The jitter disk 933 is provided with symmetrically arranged linkage plates 936 and force-receiving rods 937. The linkage plates 936 are provided with sliding holes that are slidably matched with the arc-shaped rod 932. One end of the force-receiving rod 937 is provided with a second arc-shaped surface 9371, and one end of the L-shaped abutting rod 934 is provided with a third arc-shaped surface 9341 that cooperates with the second arc-shaped surface 9371. The two fixed seats 931 are arranged on the outer wall of the lower suspension plate 91. The arc-shaped rod 932 is arranged between the two fixed seats 931. The jitter disk 933 is arranged on the third rotating shaft 921. All the L-shaped abutting rods 934 are arranged at equal intervals along the height direction of the stacking rack 1.

[0048] The blank plate 10 gradually becomes inclined at the tail end of the conveyor belt 2, and then the blank plate 10 abuts against the auxiliary supporting plate 92. The auxiliary supporting plate 92 is in an inclined state. Then, the blank plate 10 slides on the auxiliary supporting plate 92 by its own gravity and the driving force of the conveyor belt 2. Then, the blank plate 10 can enter the storage cavity. Subsequently, the head end of the blank plate 10 gradually drops onto the bearing plate 11. The bearing plate 11 is also in an inclined state. The blank plate 10 can also slide on the bearing plate 11 by its own weight. Then, the blank plate 10 can completely enter the storage cavity. In order to prevent the blank plate 10 from staying on the auxiliary supporting plate 92, when the stacking rack 1 moves downward through the alignment adjustment mechanism 5, the third arc-shaped surface 9341 of the L-shaped abutting rod 934 abuts against the second arc-shaped surface 9371 of the force-receiving rod 937. Then, the force-receiving rod 937 rotates due to the abutting force. The force-receiving rod 937 drives the jitter disk 933 and the third rotating shaft 921 to rotate synchronously around the axis of the third rotating shaft 921. The jitter disk 933 drives the linkage plate 936 to rotate synchronously. The linkage plate 936 compresses the third spring 935, causing the third spring 935 to be compressed. The third rotating shaft 921 drives the inclination angle of the auxiliary supporting plate 92 to increase. After the L-shaped abutting rod 934 disengages from the force-receiving rod 937, the third spring 935 drives the linkage plate 936 to reset by its elastic force. The jitter disk 933, the third rotating shaft 921, and the auxiliary supporting plate 92 reset, so that the auxiliary supporting plate 92 makes a jitter. The blank plate 10 staying on the auxiliary supporting plate 92 can fall into the storage cavity through this jitter, ensuring that the blank plate 10 can completely enter the storage cavity.
