Description

Technical Field

[0001] The present application relates to the technical field of metal sheet punching, and in particular to an automatic plate cutting device and an automatic plate cutting method for metal coils. Background Art

[0002] During the production process of stoves, it is necessary to make an outer barrel body. The barrel body generally includes a barrel body and a barrel bottom. The general production process is to cut the original plate into a blank, bend the blank into shape through a rolling machine, and then fix the joints by welding. At this time, the barrel body can be formed. The raw material of the barrel bottom is the cut circle. The barrel bottom is fixed to the edge of one end of the barrel body through a welding process. After sealing the bottom, the barrel body is finally formed for subsequent processing.

[0003] Generally, the raw materials are long wound sheets, which are transported to the punching machine through a feeding rack. First, they are cut into sheets of suitable length. At the same time, the sheets are punched to form the required holes. Generally, the formed sheets need to be taken to the next process for bending, which is more troublesome. Summary of the invention

[0004] In order to facilitate the conveying of punched plates, the present application provides an automatic plate cutting device and an automatic plate cutting method for metal coils.

[0005] In the first aspect, the present application provides an automatic plate cutting device for metal coils, which adopts the following technical solution: an automatic plate cutting device for metal coils, comprising a material storage rack and a punching die arranged on one side of the material storage rack, a feeding mechanism is arranged on the side of the punching die away from the material storage rack, and the feeding mechanism comprises a feeding conveyor belt arranged on one side of the punching die and a limiting frame rod arranged on the upper side of the feeding conveyor belt.

[0006] By adopting the above technical solution, first, when the material is formed, the resistance of one end of the unprocessed material belt can make the plate move slightly and contact the upper side of the feeding conveyor belt. The movement of the feeding conveyor belt can drive the plate to move toward another process, and the limiting frame rod can make the plate keep moving normally on the feeding conveyor belt, thereby facilitating the transportation of the punched plate.

[0007] Preferably, the punching die comprises a bottom die seat and a die-cutting seat slidably connected to the bottom die seat in a vertical direction, a feeding platform is lifted and lowered on the bottom die seat, and a roller is rotatably connected to the feeding platform for contacting the lower side of the material.

[0008] By adopting the above technical solution, when the punching is completed and the feeding table is raised, the roller will contact the lower side of the material, so that the roller can use friction to make the material move toward the side of the feeding conveyor belt, which is convenient for feeding.

[0009] Preferably, a torsion spring is arranged on the rotating shaft of the roller, and a linkage member for driving the roller to rotate and store potential energy is arranged on the die-cutting seat.

[0010] By adopting the above technical solution, when the die-cutting seat is close to the bottom die seat, the linkage will be connected to the rotating shaft, so that the roller will rotate, and the torsion spring will store potential energy to facilitate reset rotation.

[0011] Preferably, the linkage member includes linkage racks arranged on both sides of the die-cutting seat and corresponding to the rotating shafts one by one, and the rotating shaft is provided with a linkage gear for meshing with the linkage racks.

[0012] By adopting the above technical solution, when the die-cutting seat is close to the bottom die seat, the linkage rack will engage with the linkage gear, which will drive the roller to rotate, and the torsion spring will also store potential energy. When the die-cutting is completed, the die-cutting seat moves, which will drive the roller to rotate in the opposite direction, thereby conveying the material. The presence of the torsion spring can ensure that the linkage gear will maintain the same position each time the die-cutting seat is docked, so that docking can be carried out.

[0013] Preferably, the bottom mold base is provided with a first lifting member connected to the feeding platform and used for driving the feeding platform to move.

[0014] By adopting the above technical solution, before die-cutting, the first lifting member lowers the feeding table, and the roller will not contact the material and will not cause interference. When the punching is completed, the roller rotates to enable the material to move.

[0015] Preferably, the linkage rack is divided into a non-contact section and a tooth groove section, the non-contact section is located on the side of the linkage rack away from the die-cutting seat, the tooth groove section is located on the side of the linkage rack close to the die-cutting seat, and the length of the tooth groove section gradually increases along the discharge direction.

[0016] By adopting the above technical solution, the length of the tooth groove sections on different linkage racks is adjusted according to the contact time between the material and the roller. In this way, the rollers will stop rotating one by one during the movement of the material, and the roller closest to the feeding mechanism will keep rotating until the linkage rack disengages.

[0017] Preferably, the bottom mold base has a waste cavity, a vibration plate is obliquely arranged on the bottom mold base and located in the waste cavity, the vibration plate is swingably arranged to return, and a driving structure for driving the vibration plate to move is arranged on the bottom mold base.

[0018] By adopting the above technical solution, the waste after punching will fall into the waste cavity and be stored on the vibration plate. The vibration plate is swung by the driving structure, so that the waste can fall along the inclined direction of the vibration plate, reducing the possibility of accumulation.

[0019] Preferably, the lower side of the vibration plate has a vibration spring connected to the bottom of the waste cavity, and the driving structure includes a striking cam rotatably connected to the bottom mold base and used to strike the vibration plate. After the feeding platform descends, the rotating shaft is linked to the striking cam through a resistance member, thereby driving the striking cam to rotate.

[0020] By adopting the above technical solution, the vibration spring can make the vibration plate swing back and forth, and when the first lifting member causes the feeding platform to descend, the resistance member will cause the rotating shaft to link with the striking cam, and at this time the linkage rack will drive the striking cam to rotate, causing the vibration plate to shake, thereby facilitating the waste to fall out.

[0021] Preferably, the resistance member includes a linkage roller rotatably connected to the bottom mold base, and a resistance wheel arranged at one end of the linkage roller. The end of the roller away from the linkage gear is fixedly connected with a linkage wheel for resisting against the resistance wheel, and the striking cam is coaxially connected to the end of the linkage roller away from the resistance wheel.

[0022] By adopting the above technical solution, after the feeding platform descends, the conflict wheel will conflict with the linkage wheel. At this time, the linkage roller rotates, so that the striking cam continuously hits the vibration plate, causing the waste to move toward the lower side.

[0023] In a second aspect, the present application provides a method for automatically cutting a metal coil, which adopts the following technical solution: A method for automatically cutting a metal coil, comprising the following steps:

[0024] S1: The die-cutting seat approaches, and the first lifting member makes the roller lower than the upper surface of the bottom die seat. The linkage rack will gradually cooperate with the linkage gear, and the roller will idle without touching the material. At the same time, the die-cutting seat performs punching and cutting operations on the material.

[0025] S2: Open the mold. First, the first lifting member makes the feeding table rise, the roller contacts the mold material, and the die-cutting seat leaves the bottom mold seat. During the rotation of the roller, the friction force makes the material move and contact the feeding conveyor belt to discharge the material.

[0026] S3: The first lifting member lowers the feeding table to facilitate the next punching.

[0027] By adopting the above technical solution, during the punching process, the roller will not contact the material first. When the punching is completed, the first lifting member causes the roller to contact the lower side of the material, and the roller can be driven to rotate through the linkage rack, so that the material moves toward the side of the feeding conveyor belt to facilitate unloading.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. After punching, the material can be transported from the feeding conveyor belt after cutting and directly sent to the next process, which is more convenient;

[0030] 2. The setting of the roller can make the material be transported to the side of the feeding conveyor belt through friction after the punching is completed;

[0031] 3. When the feeding table descends, the resistance wheel and the linkage wheel come into contact. When the linkage rack makes the roller rotate and stores potential energy, the striking cam will hit the vibration plate and collect the waste to one end. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0040] The present application is further described in detail below in conjunction with the accompanying drawings.

[0041] The embodiment of the present application discloses an automatic plate cutting device for metal coils, including a material storage rack 100, a punching die 110 arranged on one side of the material storage rack 100, and a feeding mechanism 120 is arranged on the side of the punching die 110 away from the material storage rack 100. The material storage rack 100 transports the material to the punching die 110 in stages, and then the material is delivered to the feeding mechanism 120 after the punching is completed, and can be directly guided to the next process.

[0042] The punching die 110 includes a bottom die seat 111 and a die cutting seat 112 which is slidably connected to the top of the bottom die seat 111 in the vertical direction. The die cutting seat 112 presses the material against the bottom die seat 111 to perform cutting and punching operations. There is a waste cavity 113 in the bottom die seat 111, and the punched waste will fall into the inside. A feeding platform 130 is provided on the bottom die seat 111 in a lifting manner. A roller 131 is rotatably connected to the feeding platform 130 for contacting the lower side of the material and conveying the material.

[0043] The bottom die base 111 has lifting grooves 132 on both sides, and the lifting grooves 132 are opened along the direction of material movement. The feeding platform 130 is slidably arranged in the lifting grooves 132 along the vertical direction. The bottom die base 111 is provided with a first lifting member connected to the feeding platform 130 and used to drive the feeding platform 130 to move. In this embodiment, the first lifting member is a cylinder 133, and the cylinder body of the cylinder 133 is fixedly installed at the bottom of the lifting groove 132, and the piston rod of the cylinder 133 is vertically arranged, and the end of the piston rod is fixedly connected to the lower side of the feeding platform 130. Three rollers 131 are arranged at intervals on both sides of the bottom die base 111, and the rotation axis of each roller 131 is perpendicular to the direction of material movement. In the blanking stage, the cylinder 133 makes the upper surface of the roller 131 lower than the upper surface of the bottom die base 111, and will not interfere with the material. When feeding is required, the feeding platform 130 is raised, and the roller 131 will make the material move toward the feeding mechanism 120.

[0044] In this embodiment, the lifting groove 132 does not penetrate the upper surface of the bottom mold base 111. The bottom mold base 111 is provided with a receiving groove 134 that penetrates the upper surface and communicates with the lifting groove 132. The cylinder 133 will make the roller 131 protrude from the receiving groove 134 to the upper surface of the bottom mold base 111 so as to contact the material. In other embodiments, a baffle can be slidably connected to the inner wall of the receiving groove 134. When the roller 131 does not contact the material, the baffle can close the receiving groove 134, so that the upper surface of the bottom mold base 111 is as flat as possible.

[0045] A torsion spring 135 is provided on the rotating shaft of the roller 131, and a linkage member for driving the roller 131 to rotate and store potential energy is provided on the die cutting seat 112. In this embodiment, the rotating shaft of the roller 131 passes through the lifting groove 132 to the outside, and a clearance groove 136 for the movement of the feeding shaft is provided on the side wall of the bottom die seat 111 along the lifting direction of the feeding table 130.

[0046] In this embodiment, the linkage member includes linkage racks 140 arranged on both sides of the die-cutting seat 112 and corresponding to the rotating shafts one by one, and a linkage gear 150 for meshing with the linkage rack 140 is arranged on one end of the rotating shaft located on the outside. In this embodiment, the linkage rack 140 is divided into a non-contact section 141 and a tooth groove section 142, the non-contact section 141 is located on the side of the linkage rack 140 away from the die-cutting seat 112, and the tooth groove section 142 is located on the side of the linkage rack 140 close to the die-cutting seat 112, and the length of the tooth groove section 142 gradually increases along the discharge direction.

[0047] The feeding mechanism 120 includes a feeding conveyor belt 121 disposed on one side of the punching die 110 and a limiting rod 122 disposed on the upper side of the feeding conveyor belt 121. The limiting rod 122 is fixed above the feeding conveyor belt 121. In this embodiment, the limiting rod 122 is in a well-shaped shape, which can well limit the material moving on the feeding conveyor belt 121.

[0048] When punching various holes on the material, waste will fall into the waste cavity 113. In order to discharge the waste, a vibration plate 160 is obliquely arranged on the bottom mold base 111 and located in the waste cavity 113. The vibration plate 160 can be swingably arranged. In this embodiment, the lower side of the vibration plate 160 and the four top corners have vibration springs 161 connected to the bottom of the waste cavity 113. At the inclined end, a waste discharge port 162 is opened on the bottom mold base 111 for discharging the waste.

[0049] The bottom mold base 111 is provided with a driving structure for driving the vibration plate 160 to move. The driving structure includes a striking cam 170 rotatably connected to the bottom mold base 111. After the feeding platform 130 descends, the rotating shaft is linked with the striking cam 170 through the abutment 180, thereby driving the striking cam 170 to rotate. The abutment 180 includes a linkage roller 181 rotatably connected to the bottom mold base 111 and an abutment wheel 182 arranged at one end of the linkage roller 181. The linkage roller 181 is parallel to the rotation axis of the roller 131. The end of the roller 131 away from the linkage gear 150 is fixedly connected with a linkage wheel 183 for abutting against the abutment wheel 182. The striking cam 170 is coaxially connected to the end of the linkage roller 181 away from the abutment wheel 182. When the roller 131 is not in contact with the material, the linkage rack 140 drives the roller 131 to rotate, and after the linkage wheel 183 and the interference wheel 182 are in conflict, the striking cam 170 is driven to directly strike the vibration plate 160 during the rotation process, so that the vibration plate 160 continuously shakes the waste to the waste outlet 162.

[0050] In order to make the vibration plate 160 swing better, the rotation angles of the striking cams 170 on both sides can be staggered, so that when rotating, the striking of the vibration plate 160 is irregular and the vibration effect is better.

[0051] The principle of the embodiment of the present application is as follows: when the die-cutting seat 112 is close to the bottom die seat 111, the linkage rack 140 will cooperate with each linkage gear 150, and the linkage rack 140 and linkage gear 150 near the feeding rack side will not contact the linkage gear 150 first due to the non-contact section 141, while the linkage rack 140 near the feeding mechanism 120 side will cooperate with the linkage gear 150, so that the roller 131 rotates, and the torsion spring 135 will store potential energy, and the roller 131 does not contact the material at this time. Then after the punching is completed, the cylinder 133 makes the feeding table 130 rise a short distance, so that the roller 131 hits the lower side of the material, and then when the die-cutting seat 112 is away from the bottom die seat 111, the linkage gear 150 will make the roller 131 rotate, and at this time, it will drive the material to move toward the feeding mechanism 120 side.

[0052] At the same time, when the die-cutting seat 112 is close to the bottom die seat 111, the linkage rack 140 will drive the resistance wheel 182 to rotate, so that the striking cam 170 strikes the vibration plate 160, so as to achieve the purpose of shaking out the waste.

[0053] Based on the above-mentioned metal coil automatic plate cutting device, the embodiment of the present application also discloses a metal coil automatic plate cutting method, comprising the following steps:

[0054] S1: The die-cutting seat 112 approaches, and the first lifting member makes the roller 131 lower than the upper surface of the bottom die seat 111, and the linkage rack 140 will gradually cooperate with the linkage gear 150, and the roller 131 will idle without touching the material, and the die-cutting seat 112 will perform a punching operation on the material;

[0055] S2: Open the mold. First, the first lifting member causes the feeding table 130 to rise, the roller 131 contacts the mold material, and the die-cutting seat 112 leaves the bottom mold seat 111. During the rotation of the roller 131, the friction force causes the material to move and contact the feeding conveyor belt 121 to discharge the material.

[0056] S3: The first lifting member lowers the feeding table 130 to facilitate the next punching.

[0057] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
