Description

Technical Field

[0001] The present invention relates to the technical field of plate production, and in particular to an automatic cutting device for plate production. Background Art

[0002] Stainless steel plates have a smooth surface, high plasticity, toughness and mechanical strength, and are resistant to corrosion from acids, alkaline gases, solutions and other media. Stainless steel plates refer to steel plates that are resistant to corrosion from weak media such as atmosphere, steam and water. During the processing of stainless steel plates, shearing machines are used to shear the plates.

[0003] After searching, the Chinese patent document with the announcement number CN115673411B discloses a shearing device for stainless steel plates, which relates to the technical field of shearing equipment. The patent includes a base, which includes a base frame 1, a base frame 2, a rotating roller and a carrier plate. The rotating roller and the carrier plate are installed between the base frames 1 and 2. The base frames 1 and 2 are both installed with pillars. A top plate is fixed to the top of the two pillars. A hydraulic telescopic rod is vertically installed on the top plate. A movable seat is provided between the two pillars. A heat sink and a knife seat are installed on the upper and lower sides of the movable seat respectively. A knife body is installed on the knife seat. The interior of the heat sink is connected to the interior of the movable seat. The telescopic end of the hydraulic telescopic rod is fixed to the movable seat. The patent rotates the steel plate material to be sheared on the installed rotating roller, transports it to the carrier plate through the rotating roller, and pushes the movable seat and the knife body installed on the knife seat to move toward the stainless steel plate to be cut by the installed hydraulic telescopic rod and cuts it.

[0004] Based on the search and existing technology, it was found that the existing plate shearing machines generally have a significant defect, that is, the feeding action and the shearing action cannot be performed at the same time, and the two must be strictly separated in terms of timing; specifically, the equipment first performs the feeding action (driving the plate to move to the predetermined shearing position), and the feeding process must be completely stopped before the shearing mechanism can start to perform the shearing action; after the shearing is completed, the equipment needs to restart the feeding action to transport the next section of the plate, and continuous shearing cannot be achieved, making it difficult to further improve the production efficiency of the entire production line.

[0019] The present invention provides an automated cutting device for plate production through improvements, which has the following improvements and advantages compared with the prior art:

[0020] First, the disc provided in the present invention enables the shearing mechanism to move back and forth in a straight line. The disc is designed based on the Archimedean spiral. When the disc pushes the shearing mechanism, there is a distance that is consistent with the direction and speed of the plate conveying. The shearing mechanism completes the cutting work in the uniform speed section, then resets and reciprocates in sequence, thereby achieving continuous cutting motion, ensuring that the feeding process does not stop, so that feeding and shearing work can be carried out simultaneously, thereby improving production efficiency;

[0021] Secondly, the reciprocating mechanism of the present invention is driven by steel, which makes the driving force larger and prevents slipping. The hydraulic drive in the existing shearing mechanism is replaced by a rigid rod that can move vertically and linearly. During the shearing movement, the rigid rod is pushed downward by the convex plate set above the shearing mechanism. The rigid rod can push the cutter to cut, making the cutting work instantaneous and saying goodbye to the hysteresis of hydraulic drive.

[0022] Third, the existing tracking shearing technology uses a screw module to make the shearing mechanism consistent with the linear feeding speed. However, since the shearing mechanism is heavy, the inertia of the shearing mechanism is large when the shearing mechanism moves. In order to protect the screw module from being damaged, the screw module cannot make the shearing mechanism have a very fast moving speed. However, the shearing mechanism of the present invention uses a disc to push, and the disc has a strong load-bearing capacity, which can enable the shearing mechanism to move back and forth faster, thereby improving the shearing efficiency.

[0038] The present invention is described in detail below, clearly and completely describing the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0039] The present invention provides an improved automatic cutting device for plate production. The technical solution of the present invention is:

[0040] like Figures 1 to 12 As shown, an embodiment of the present invention provides an automated cutting device for plate production, comprising an inner frame 1, a front frame 2 and a rear frame 3 being fixed to the front and rear ends of the inner frame 1 respectively;

[0041] A roller conveyor 8 is fixedly installed in the rear frame 3;

[0042] A shearing mechanism 11 for shearing is provided in the front frame 2;

[0043] A walking structure is provided in the front frame 2 to enable the shearing mechanism 11 to move linearly inside the front frame 2;

[0044] Both sides of the rear frame 3 are provided with a rotation hole located above the roller conveyor 8, and a synchronization rod 10 is installed in the two rotation holes for common rotation. A rotation mechanism for rotating the synchronization rod 10 is provided in the rear frame 3;

[0045] A plurality of discs 9 are fixed to the outside of the synchronization rod 10 and are arranged coaxially therewith. A guide groove 53 is provided on both circular surfaces of the disc 9. The guide groove 53 is composed of two Archimedean spirals with the center of the disc 9 as the starting point ( Figure 12 In the ab segment and the cd segment, the two Archimedean spirals are symmetrically distributed, and the two adjacent ends of the two Archimedean spirals are connected by a circular arc. A plurality of push rods 51 are slidably inserted into the rear side of the front frame 2. One end of the plurality of push rods 51 is connected to the shearing mechanism 11. The plurality of push rods 51 are respectively aligned one-to-one with the plurality of disks 9. The other end of the push rods 51 is fixed with a horizontal plate 52. One end of the horizontal plate 52 is rotatably mounted with a cylinder 54. The cylinder 54 is slidably set in the guide groove 53.

[0046] The Archimedean spiral is described as follows: the radius of each point of the Archimedean spiral increases uniformly over time. The Archimedean spiral is an existing theory that is a way to convert uniform circular motion into uniform linear motion. When the Archimedean spiral pushes the push rod 51, the push rod 51 maintains a uniform speed.

[0047] The following is the derivation formula, which is for reference only:

[0048] Definition of Archimedean spiral. In polar coordinate system, the equation of Archimedean spiral is: r=a+bθ;

[0049] in:

[0050] r is the distance to the origin (polar diameter);

[0051] θ is the angle (polar angle);

[0052] a is the initial radius (the radius when θ=0, i.e. the base circle radius);

[0053] b is a constant that controls the “tightness” of the spiral;

[0054] It can be seen that when the disc 9 rotates at a uniform speed (i.e., θ increases uniformly with time t, θ=ωt, ω is the angular velocity), the radial dimension r of the ab end or cd end of the guide groove 53 also increases uniformly with time t;

[0055] When the disk 9 rotates at a constant angular velocity ω, the rotation angle θ of the disk 9 = ωt;

[0056] The displacement s of the push rod 51 is defined as the distance moved outward from the base circle position; therefore, s=ra;

[0057] Substitute into the spiral equation: s=(a+bθ)-a=bθ;

[0058] Then substitute θ=ωt into: s=bωt;

[0059] Conclusion: The displacement s of the push rod 51 is proportional to the time t (s=(bω)t); the proportional constant bω is the linear velocity v.

[0060] Velocity: v = ds / dt = d(bωt) / dt = bω (constant);

[0061] Acceleration: a=dv / dt=d(bω) / dt=0 (0 in the motion segment);

[0062] Summary: The derivation result v = bω = constant clearly shows that when the disk 9 rotates at a constant speed (ω is constant), the push rod 51 moves linearly at a constant speed bω;

[0063] From the above connection relationship, it can be seen that: the plate to be cut is placed on the roller conveyor 8, and the roller conveyor 8 transports the plate to the shearing mechanism 11 at a uniform speed. At the same time, the rotating mechanism rotates the synchronous rod 10, and the disc 9 on the synchronous rod 10 rotates. The guide groove 53 of the disc 9 pushes the push rod 51 out with the help of the cylinder 54. When the cylinder 54 is in an arc, the push rod 51 is in a speed change state, and the shearing mechanism 11 does not work. When the cylinder 54 enters the Archimedean spiral from the arc, the push rod 51 is in a uniform speed state (it needs to be explained here that the uniform speed of the push rod 51 is first measured, and then the roller conveyor 8 is speed-regulated so that its feeding speed is consistent with the pushing speed of the push rod 51). The shearing mechanism 11 starts to shear. The shearing is completed in this uniform speed section. When the push rod 51 is pulled back, the shearing mechanism 11 is in a stopped working state. This reciprocating process realizes continuous shearing and improves cutting efficiency.

[0064] Specifically, in conjunction with Figure 1 As shown, the rotating mechanism includes a servo motor 7, a first synchronous wheel 5 and a second synchronous wheel 6. The servo motor 7 is fixed to the rear frame 3. The output shaft of the servo motor 7 is coaxially fixed to the first synchronous wheel 5. The second synchronous wheel 6 is coaxially fixed to the synchronous rod 10. The first synchronous wheel 5 and the second synchronous wheel 6 are jointly covered with a synchronous belt 4.

[0065] From the above connection relationship, it can be seen that the servo motor 7 rotates the first synchronous wheel 5 through the output shaft, the first synchronous wheel 5 rotates the second synchronous wheel 6 through the synchronous belt 4, and the second synchronous wheel 6 drives the synchronous rod 10 to rotate.

[0066] Specifically, in conjunction with Figure 1 , Attachment Figure 4 , Attachment Figure 5 and attached Figure 6 As shown, the shearing mechanism 11 includes a first recessed frame 12 and a second recessed frame 13. The recess of the first recessed frame 12 is arranged opposite to the recess of the second recessed frame 13, and the first recessed frame 12 is located at the top of the front frame 2, and the two ends of the first recessed frame 12 are respectively fixed to the two ends in the recess of the second recessed frame 13. Grooved guide rails 15 are fixed to the top of both sides of the inner frame 1. A set of running wheels 16 are rotatably installed at both ends of the first recessed frame 12. The two sets of running wheels 16 are respectively arranged in the grooves of the two grooved guide rails 15. One end of the push rod 51 is fixed to the first recessed frame 12.

[0067] It can be seen from the above connection relationship that the first recessed frame 12 moves along the groove guide rail 15 via the running wheels 16 , so that the first recessed frame 12 and the second recessed frame 13 can move linearly in the front frame 2 .

[0068] Specifically, in conjunction with Figure 5 and attached Figure 6 As shown, the shearing mechanism 11 further includes a plurality of rigid rods 17 slidably plugged into the top of the first recessed frame 12. A reference plate 26 is fixed to the bottom ends of the plurality of rigid rods 17. A cutter 27 is fixed to one side of the reference plate 26. A pressing mechanism 14 is provided at the bottom of the reference plate 26. A first guide structure 23 is provided at the top of the front frame 2 to move the rigid rods 17 on the first recessed frame 12 downward during the forward movement of the first recessed frame 12.

[0069] From the above connection relationship, it can be seen that when the rigid rod 17 moves downward, the rigid rod 17 drives the reference plate 26 to move downward, the cutter 27 and the pressing mechanism 14 on the reference plate 26 move downward with the reference plate 26, and the cutter 27 shears the plate.

[0070] Specifically, in conjunction with Figure 6 As shown, the clamping mechanism 14 includes a plurality of double-section telescopic cylinders 30, one end of each double-section telescopic cylinder 30 is fixed to the bottom of the reference plate 26, and the other end of each double-section telescopic cylinder 30 is commonly fixed with a pressing plate 29, and the outer side of each double-section telescopic cylinder 30 is provided with a spring 28, and the two ends of each spring 28 are respectively fixed to the pressing plate 29 and the reference plate 26;

[0071] From the above connection relationship, it can be seen that when the reference plate 26 moves downward, the pressing plate 29 of the clamping mechanism 14 contacts the plate, the double-section telescopic cylinder 30 is compressed, the spring 28 is compressed, and the spring 28 generates a reaction force to make the pressing plate 29 press the plate.

[0072] Specifically, in conjunction with Figure 1 , Attachment Figure 6 , Attachment Figure 7 , Attachment Figure 8 , Attachment Figure 11 and attached Figure 12As shown, the first guide structure 23 includes a first guide plate 31, a first straight groove 32 arranged horizontally is provided on the outer side of the first guide plate 31, and an angle groove 33 is provided on the outer side of the first guide plate 31, which is located below the first straight groove 32. The angle groove 33 is located in the middle of the first straight groove 32, and both ends of the angle groove 33 are connected to the first straight groove 32. The two ends of the angle groove 33 do not coincide with the two ends of the first straight groove 32. The first straight groove 32 and the angle groove 33 form a first guide groove, and two first circular holes are provided on the outer side of the first guide plate 31. First rotating columns 39 are rotatably installed in the two first circular holes. Two first cylinders 38 respectively coaxially arranged with the two first rotating columns 39 are fixed on the outer side of the first guide plate 31. The first cylinder 38 and the first rotating column 39 coaxially arranged therewith are jointly fixed with a first coil spring 40, and the two first rotating columns 39 are respectively fixed with a first limiting plate 34 and a second limiting plate The first limit plate 35 and the second limit block 37 are fixed to the outer side of the first guide plate 31, and the first limit block 35 and the second limit block 37 are in contact with the first limit plate 34 and the second limit plate 36 respectively. The first limit block 35 prevents the first limit plate 34 from rotating upward, and the second limit block 37 prevents the second limit plate 36 from rotating downward. The first limit plate 34 is located at one end of the first guide plate 31, and the first limit plate 34 has the same inclination as the angle slot 33. The bottom edge of the first limit plate 34 coincides with the top edge of the angle slot 33. The second limit plate 36 is located at the other end of the first guide plate 31, and the second limit plate 36 is parallel to the first straight slot 32. The top edge of the second limit plate 36 coincides with the bottom edge of the first straight slot 32. The top of the rigid rod 17 is fixed with a first support plate 19, and one end of the first support plate 19 is rotatably mounted with a first guide post 20, which is disposed in the first guide slot;

[0073] Through the above connection relationship, it can be known that: when the entire shearing mechanism 11 is located at the rear end of the front frame 2, it is set to the starting state. At this time, the first guide post 20 is located at one end of the first straight slot 32, and the cylinder 54 is located in the guide slot bc section. The disc 9 rotates, and when the cylinder 54 slides in the guide slot bc section, the push rod 51 is in the speed change state, and the first guide post 20 slides in the first straight slot 32 until it contacts the first limit plate 34. At this time, the rigid rod 17 does not move down. When the cylinder 54 enters the ab section, the push rod 51 moves at a uniform speed. Due to the setting of the first limit block 35, the first limit plate 34 cannot rotate upward, so the first guide post 20 enters the angle slot 33 along the first limit plate 34 until the first guide post 20 contacts the second limit plate 36. At this time, the rigid rod 17 moves down first and then up. When the cylinder 54 slides in the guide slot ad section, that is, when it enters point a, the first guide post 2 When the first guide post 20 is in the first straight slot 32, the first limit plate 36 is reset. When the cylinder 54 moves from the middle position of the ad section to the middle position of the bc end, the first guide post 20 moves backward along the first straight slot 32. Due to the setting of the second limit block 37, the second limit plate 36 cannot rotate downward, so the first guide post 20 cannot enter the angle slot 33. The rigid rod 17 is in a pulled-up state. During the movement of the first guide post 20, it pushes the first limit plate 34. Although the first guide post 20 at the top of the rigid rod 17 falls into the angle slot 33 due to its own weight, the entire shearing mechanism 11 is in a backward moving state, and the first guide post 20 is still pulled back to the rear end of the first straight slot 32.

[0074] Specifically, in combination with Figure 1 -Attached Figure 3 And attached Figure 6 -Attached Figure 12As shown, the shearing mechanism 11 also includes a plurality of top rods 18 that are slidably inserted into the bottom of the second recessed frame 13. The top ends of the plurality of top rods 18 are commonly fixed with a bottom support plate 25. The bottom of the front frame 2 is provided with a second guide structure 24 that moves the top rods 18 on the first recessed frame 12 upward during the forward movement of the first recessed frame 12. The second guide structure 24 includes a second guide plate 41. The outer side of the second guide plate 41 is provided with a second horizontal straight groove 42. The outer side of the second guide plate 41 is provided with a flat groove 4 with a track of "︺". 3. The flat groove 43 is located in the middle of the second straight groove 42. The flat groove 43 is inverted and located above the second straight groove 42. Both ends of the angle groove 33 are connected to the second straight groove 42. The two ends of the flat groove 43 do not overlap with the two ends of the second straight groove 42. The second straight groove 42 and the flat groove 43 form a second guide groove. Two second circular holes are opened on the outer side of the second guide plate 41. The second rotating columns 49 are rotatably installed in the two second circular holes. The outer side of the second guide plate 41 is fixed with two second rotating columns 49 respectively. The cylinder 48, the second cylinder 48 and the second rotating column 49 arranged coaxially therewith are jointly fixed with a second coil spring 50, the two second rotating columns 49 are respectively fixed with the third limit plate 45 and the fourth limit plate 46, and the outer side of the second guide plate 41 is fixed with a third limit block 44 and a fourth limit block 47, the third limit block 44 and the fourth limit block 47 are respectively in contact with the third limit plate 45 and the fourth limit plate 46, the third limit block 44 prevents the third limit plate 45 from rotating upward, and the fourth limit block 47 prevents the fourth limit plate 46 cannot rotate downward, the third limiting plate 45 is located at one end of the second guide plate 41, the third limiting plate 45 is parallel to the second straight groove 42, the bottom edge of the third limiting plate 45 coincides with the top edge of the second straight groove 42, the fourth limiting plate 46 is located at the other end of the second guide plate 41, the top edge of the fourth limiting plate 46 coincides with the bottom edge of the inclined portion of the flat groove 43, the top end of the ejector rod 18 is fixed with the second support plate 21, one end of the second support plate 21 is rotatably mounted with the second guide post 22, and the second guide post 22 is disposed in the second guide groove;

[0075] Through the above connection relationship, it can be known that: when the entire shearing mechanism 11 is located at the rear end of the front frame 2, it is set to the starting state. At this time, the second guide post 22 is located at the rear end of the second straight groove 42, and the disc 9 rotates. When the cylinder 54 slides in the guide groove bc section, the push rod 51 is in the speed change state, and the second guide post 22 slides in the second straight groove 42 until it contacts the fourth limit plate 46. At this time, the push rod 18 does not move up. When the cylinder 54 enters the ab section, the push rod 51 moves at a uniform speed. Due to the setting of the fourth limit block 47, the fourth limit plate 46 cannot rotate downward, so the second guide post 22 enters the flat groove 43 along the fourth limit plate 46 until the second guide post 22 contacts the third limit plate 45. At this time, the push rod 18 does not move up. The rod 18 first moves up, then maintains its state unchanged, and finally moves down. When the cylinder 54 slides in the guide groove section ad, that is, when it enters point a, the second guide post 22 pushes the third limit plate 45 downward. At this time, the third limit plate 45 drives the second rotating post 49 fixed thereto to rotate, and the second coil spring 50 is rewound. When the cylinder 54 enters the middle position of the ad section, the second guide post 22 completely enters the second straight groove 42, and the third limit plate 45 is reset. When the cylinder 54 moves from the middle position of the ad section to the middle position of the bc end, the second guide post 22 moves backward along the second straight groove 42. During the movement of the second guide post 22, it will push the fourth limit plate 46 until the second guide post 22 returns to the rear end of the second straight groove 42.

[0076] Working principle:

[0077] In the first step, the sheet material to be cut is placed on the roller conveyor 8, which transports the sheet material to the shearing mechanism 11 at a uniform speed.

[0078] In the second step, while the first step is being performed, the servo motor 7 is started. The servo motor 7 rotates the first synchronous wheel 5 through the output shaft. The first synchronous wheel 5 rotates the second synchronous wheel 6 through the synchronous belt 4. The second synchronous wheel 6 drives the synchronous rod 10 to rotate. The disc 9 on the synchronous rod 10 rotates. The guide groove 53 of the disc 9 uses the cylinder 54 to make the push rod 51 reciprocating linear motion on the first recessed frame 12;

[0079] The specific process of the disc 9 driving the push rod 51 to perform a reciprocating linear motion and the following process of the shearing mechanism 11 are as follows:

[0080] (1) The entire shearing mechanism 11 is set to the starting state when it is located at the rear end of the front frame 2. At this time, the first guide post 20 is located at one end of the first straight slot 32, the second guide post 22 is located at the rear end of the second straight slot 42, and the cylinder 54 is located in the guide slot bc section; the disc 9 rotates, and when the cylinder 54 slides in the guide slot bc section, the push rod 51 is in the speed change state, and the first guide post 20 slides in the first straight slot 32 until it contacts the first limit plate 34. At this time, the rigid rod 17 does not move downward, and the second guide post 22 slides in the second straight slot 42 until it contacts the fourth limit plate 46. At this time, the push rod 18 does not move upward;

[0081] (2) When the cylinder 54 enters the ab section, the push rod 51 moves at a uniform speed. Due to the setting of the first limit block 35, the first limit plate 34 cannot rotate upward, so the first guide column 20 enters the angle groove 33 along the first limit plate 34 until the first guide column 20 contacts the second limit plate 36. At this time, the rigid rod 17 moves down first and then up. Due to the setting of the fourth limit block 47, the fourth limit plate 46 cannot rotate downward, so the second guide column 22 enters the flat groove 43 along the fourth limit plate 46 until the second guide column 22 contacts the third limit plate 45. At this time, the push rod 18 first moves up, then maintains the state unchanged (in this process, the bottom support plate 25 is lifted up by the push rod 18 and contacts the plate), and finally moves down;

[0082] During the downward movement of the above-mentioned middle rigid rod 17, the rigid rod 17 drives the reference plate 26 to move downward. At this time, the top rod 18 lifts the bottom support plate 25 and contacts the plate. When the reference plate 26 moves downward, the pressure plate 29 of the clamping mechanism 14 contacts the plate, the double-section telescopic cylinder 30 is compressed, and the spring 28 is compressed. The spring 28 generates a reaction force to cause the pressure plate 29 to press the plate onto the bottom support plate 25. The reference plate 26 continues to move downward, and the cutter 27 on the reference plate 26 shears the plate.

[0083] (3) When the cylinder 54 slides in the guide groove section ad, that is, when it enters point a, the first guide post 20 pushes the second limit plate 36 upward. At this time, the second limit plate 36 drives the first rotating post 39 fixed thereto to rotate, and the first coil spring 40 rewinds. When the cylinder 54 enters the middle position of the ad section, the first guide post 20 completely enters the first straight slot 32, and the second limit plate 36 resets. When the cylinder 54 moves from the middle position of the ad section to the middle position of the bc end, the first guide post 2 0 moves backward along the first straight slot 32. Due to the setting of the second limit block 37, the second limit plate 36 cannot rotate downward, so the first guide post 20 cannot enter the angle slot 33. The rigid rod 17 is in the pulled-up state. During the movement of the first guide post 20, it pushes the first limit plate 34. Although the rigid rod 17 causes the first guide post 20 on the top to fall into the angle slot 33 due to its own weight, the entire shearing mechanism 11 is in the backward movement state, and the first guide post 20 is still pulled back to the rear end of the first straight slot 32.

[0084] During the above process, the following process also occurs: the second guide post 22 pushes the third limit plate 45 downward. At this time, the third limit plate 45 drives the second rotating post 49 fixed to it to rotate, and the second coil spring 50 is rewound. When the cylinder 54 enters the middle position of the ad section, the second guide post 22 completely enters the second straight groove 42, and the third limit plate 45 is reset. When the cylinder 54 moves from the middle position of the ad section to the middle position of the bc end, the second guide post 22 moves backward along the second straight groove 42. During the movement of the second guide post 22, it will push the fourth limit plate 46 until the second guide post 22 returns to the rear end of the second straight groove 42.
