Description

Technical Field

[0001] The utility model relates to the technical field of steel barrel cutting equipment, in particular to a steel barrel cutting device. Background Art

[0002] In order to save resources, the old steel barrels used in the chemical industry are generally reused after being refurbished many times. However, for some old steel barrels that cannot meet the use standards after being refurbished many times, they need to be disassembled to make steel plates for recycling. When disassembling a steel barrel, it is necessary to cut off the bottom and lid at both ends of the steel barrel, and then cut open the side wall of the steel barrel to send it into a flattening device for flattening. In the existing processing operations, the bottom, lid and side wall of the steel barrel are often cut manually by operating semi-automatic equipment in sequence, which requires frequent handling of the steel barrel, resulting in high labor intensity of the operators and low cutting efficiency. Content of the Utility Model

[0003] Aiming at the above problems, the purpose of the utility model is to provide a steel barrel cutting device, which can automatically cut the bottom, lid and side wall of the steel barrel, improve the cutting efficiency and reduce the labor intensity of the operators.

[0004] The purpose of the utility model is realized by the following technical solutions:

[0005] A steel barrel cutting device is provided, which includes a frame. A sliding mechanism for moving the steel barrel is arranged on the frame, a clamping mechanism for clamping and positioning the steel barrel is arranged above the sliding mechanism, and an end cover cutting mechanism for cutting the end cover of the steel barrel and a transverse cutting mechanism for cutting the side wall of the steel barrel are arranged above the clamping mechanism. The clamping mechanism includes two chuck plates that are oppositely and rotatably arranged on both sides of the sliding mechanism, a first driving unit for driving the two chuck plates to move away from or close to each other, and a second driving unit for driving the chuck plates to lift. The end cover cutting mechanism includes a cutting disc and a third driving unit for driving the cutting disc to rotate. The cutting disc can be connected to the chuck plate and drive the chuck plate to rotate synchronously. The two cutting discs respectively correspond to the cutting positions of the lids and bottoms at both ends of the steel barrel.

[0006] The steel barrel cutting device designed in this scheme can realize the automatic cutting of the barrel cover and barrel bottom at both ends of the steel barrel, as well as the side wall of the steel barrel. The steel barrel is placed on the sliding mechanism, and the sliding mechanism is controlled to slide through the control system to transfer the steel barrel to between the two clamping discs of the clamping mechanism; the first driving unit drives the two clamping discs to approach to clamp the steel barrel; then, the second driving unit drives the clamping disc to rise, so that the clamping disc is connected with the cutting disc by transmission and remains stable; the cross-cutting mechanism automatically starts to work and cuts the side wall of the steel barrel; after the cross-cutting mechanism completes the cutting, the third driving unit drives the cutting disc to rotate, and drives the clamping disc to rotate, so that the steel barrel rotates, and the cutting disc cuts off the barrel cover and barrel bottom along the cutting point between the barrel cover and the barrel bottom; after the cutting is completed, the clamping mechanism releases the cut steel barrel to the sliding mechanism, and the sliding mechanism transfers the cut steel barrel out. The entire cutting process is closely connected, realizing the automatic transmission and cutting of the steel barrel, and the cutting of the barrel bottom, barrel cover and side wall of the steel barrel can be completed without manual intervention, which improves the cutting efficiency and reduces the labor intensity of the operators.

[0007] Furthermore, the clamping mechanism also includes a supporting slide rail and a slide plate slidably connected to the supporting slide rail, the chuck is rotatably mounted on the slide plate, the first drive unit is drivingly connected to the supporting slide rail, the second drive unit is arranged on the supporting slide rail, and the output end of the second drive unit is connected to the slide plate.

[0008] The chuck is installed on the slide through a bearing seat, the slide is slidably connected to the supporting rail, a supporting platform is provided at the bottom of the supporting rail, the second drive unit is installed on the supporting platform, and the output end of the second drive unit is connected to the slide, the second drive unit can drive the slide to slide up and down along the rail, and the steel drum can remain stable during the lifting process through the design of the rail structure; the side of the supporting rail facing away from the slide is connected to the output end of the first drive unit, the first drive unit can drive the supporting rail together with the slide, the chuck and the second drive unit to move, and after the chuck clamps the steel drum, the second drive unit can perform the lifting action.

[0009] Furthermore, the chuck includes a positioning disk and a first toothed disk fixedly connected to the positioning disk, and a rotation axis of the positioning disk coincides with a rotation axis of the first toothed disk.

[0010] The barrel bottom and barrel cover at both ends of the steel barrel have a groove structure. The thickness of the positioning plate is the same as the depth of the groove. During the clamping process, the positioning plate goes deep into the groove, the end face of the positioning plate abuts against the bottom of the groove, and the side wall of the positioning plate is in contact with the inner side of the groove, thereby clamping the steel barrel; the positioning plate is fitted and fixed to the first toothed plate, and the rotation axes of the two coincide, and the rotation of the first toothed plate synchronously drives the positioning plate and the clamped steel barrel to rotate.

[0011] Further, the diameter of the first toothed disc is greater than the diameter of the positioning disc.

[0012] The diameter of the first toothed disc is larger than that of the positioning disc. When the positioning disc clamps the steel drum, the bottom and the end face of the lid of the steel drum are further pressed into contact with the surface of the first toothed disc, further ensuring the stability of clamping the steel drum.

[0013] Furthermore, the cutting disc includes a cutter disc and a second toothed disc fixedly connected to the cutter disc, and the rotation axes of the cutter disc and the second toothed disc coincide.

[0014] The cutter disc faces the cutting positions of the bottom and the lid of the steel drum. After the second driving unit drives the chuck to rise, the cutter disc and the positioning disc form a shearing structure; the cutter disc is fixedly attached to the second toothed disc and their rotation axes coincide, and the cutter disc rotates with the second toothed disc to cut off the bottom and the lid along the cutting positions of the steel drum.

[0015] Furthermore, the diameter of the second toothed disc is smaller than that of the cutter disc, and the first toothed disc and the second toothed disc can be meshed and connected.

[0016] Since the diameter of the second toothed disc is smaller than that of the cutter disc, after the second driving unit drives the chuck to rise, the first toothed disc and the second toothed disc are meshed and connected, and the cutter disc and the positioning disc approach to form a shearing structure.

[0017] Furthermore, the output end of the third driving unit is drivingly connected to the second toothed disc. When the first toothed disc and the second toothed disc are meshed and connected, the third driving unit drives the second toothed disc to rotate and drives the first toothed disc to rotate.

[0018] After the second driving unit drives the chuck to rise, the first toothed disc and the second toothed disc are meshed and connected. The third driving unit drives the second toothed disc to rotate, and the second toothed disc drives the first toothed disc to rotate, so that the steel drum rotates together with the chuck; the shearing structure formed by the cutter disc and the positioning disc cuts off the bottom and the lid along the cutting positions of the steel drum during the rotation of the steel drum.

[0019] Furthermore, the cross-cutting mechanism includes a cutter, a fourth driving unit, a mounting plate, and a fifth driving unit. The fourth driving unit is arranged on the mounting plate, the cutter is connected to the output end of the fourth driving unit, the fourth driving unit can drive the cutter to perform a reciprocating linear motion, the mounting plate is connected to the output end of the fifth driving unit, and the fifth driving unit can drive the mounting plate to move up and down.

[0020] Before cutting the bottom and lid of the steel drum, first use the transverse cutting mechanism to cut the side wall of the steel drum. Before the steel drum enters the clamping mechanism, the cutter is at the top of the frame to avoid affecting the transfer of the steel drum by the sliding mechanism; when the steel drum is clamped and lifted, the fifth drive unit drives the mounting plate to move downwards to bring the cutter closer to the steel drum. When the cutter moves down to the appropriate position, the fourth drive unit drives the cutter to move along the side wall of the steel drum to cut open the side wall of the steel drum; after the cutting is completed, the fifth drive unit drives the mounting plate to move upwards to make the cutter return to its original position.

[0021] Further, the sliding mechanism includes a sliding plate, a sixth drive unit located below the sliding plate and drivingly connected to the sliding plate, and two groups of bearing brackets provided on the sliding plate. The sixth drive unit can drive the sliding plate to perform reciprocating linear motion so that the two groups of bearing brackets are alternately located below the clamping mechanism.

[0022] There are two groups of alternately used bearing brackets on the sliding plate for placing two steel drums for cutting. When one steel drum is cut, the sixth drive unit drives the sliding plate to move so that the cut steel drum is moved out of the clamping mechanism, and the steel drum on the other bearing bracket is sent into the clamping mechanism. This way of linked parallel feeding and discharging is conducive to improving the processing efficiency.

[0023] Further, the bearing bracket includes four rollers arranged in an array on the sliding plate.

[0024] The bearing bracket consists of four rollers. The roller structure is convenient for manual loading and unloading of the steel drum and for adjusting the position of the steel drum; at the same time, this structure is simple to install and disassemble, facilitating maintenance and replacement.

[0025] Compared with the prior art, the beneficial effects of the present utility model are:

[0026] The steel drum cutting device designed in this solution can realize the automatic cutting of the lid and bottom of both ends of the steel drum and the side wall of the steel drum. Place the steel drum on the sliding mechanism, and through the control system, control the sliding of the sliding mechanism to transfer the steel drum between the two chucks of the clamping mechanism; the first drive unit drives the two chucks to approach to clamp the steel drum; then, the second drive unit drives the chuck to rise so that the chuck is drivingly connected to the cutting disc and remains stable; the transverse cutting mechanism automatically starts working to cut the side wall of the steel drum; after the transverse cutting mechanism finishes cutting, the third drive unit drives the cutting disc to rotate and drives the chuck to rotate so that the steel drum rotates, and the cutting disc cuts off the lid and bottom along the cutting position of the lid and bottom; after the cutting is completed, the clamping mechanism releases the cut steel drum onto the sliding mechanism, and the sliding mechanism transfers the cut steel drum out. The whole cutting process is closely connected, realizing the automatic transmission and cutting of the steel drum, and can complete the cutting of the bottom, lid and side wall of the steel drum without manual intervention, improving the cutting efficiency and reducing the labor intensity of the operators.

The clamping mechanism 2 includes two clamping disks 21 that are relatively and rotatably arranged on both sides of the sliding mechanism 1, a first driving unit 20 for driving the two clamping disks 21 to move away from or close to each other, and a second driving unit 22 for driving the clamping disks 21 to move up and down. In this embodiment, the first driving unit 20 and the second driving unit 22 adopt existing driving technologies, such as the driving method of a cylinder or an oil cylinder; the cylinder or the oil cylinder is arranged on the side of the frame 5 and is drivingly connected to one of the clamping disks 21, and the other clamping disk 21 is relatively fixed on the frame. The end cover cutting mechanism 3 includes a cutting disk 31 located above the clamping disk and a third driving unit for driving the cutting disk 31 to rotate. The cutting disk 31 can be connected to the clamping disk 21 and synchronously drive the clamping disk 21 to rotate. The two cutting disks 31 respectively correspond to the cutting positions of the barrel covers and the barrel bottoms at both ends of the steel barrel. In this embodiment, the third driving unit adopts existing driving technologies, such as using a rotary motor. The rotary motor is installed and fixed on the side of the frame, and its rotating shaft is connected to the cutting disk 31 to drive the cutting disk 31 to rotate. The rotary motor is covered with a protective cover for safety protection.

[0034] The steel barrel cutting device designed in this solution can realize the automatic cutting of the barrel covers and the barrel bottoms at both ends of the steel barrel, as well as the side wall of the steel barrel. Place the steel barrel on the sliding mechanism 1, and through the control system, control the sliding of the sliding mechanism 1 to transfer the steel barrel between the two clamping disks 21 of the clamping mechanism 2; the first driving unit 20 drives the two clamping disks 21 to approach each other to clamp the steel barrel; then, the second driving unit 22 drives the clamping disks 21 to rise, so that the clamping disks 21 are drivingly connected to the cutting disk 31 and remain stable; the transverse cutting mechanism 4 automatically starts working to cut the side wall of the steel barrel; after the transverse cutting mechanism 4 finishes cutting, the third driving unit drives the cutting disk 31 to rotate and drives the clamping disks 21 to rotate, so that the steel barrel rotates, and the cutting disk 31 cuts off the barrel covers and the barrel bottoms along the cutting positions of the barrel covers and the barrel bottoms; after cutting is completed, the clamping mechanism 2 releases the cut steel barrel onto the sliding mechanism 1, and the sliding mechanism 1 transfers the cut steel barrel out. The entire cutting process is closely connected, realizing the automatic transmission and cutting of the steel barrel. The barrel bottom, barrel cover, and side wall of the steel barrel can be cut without manual intervention, improving the cutting efficiency and reducing the labor intensity of the operators.

[0035] Such as Figure 1 and Figure 2As shown, the clamping mechanism 2 further includes a support slide rail 23 and a slide plate 24 slidably connected to the support slide rail 23. The chuck 21 is provided with a rotating shaft and is installed on the slide plate 24 through a bearing seat. The output end of the first driving unit 20 is drivingly connected to the support slide rail 23. A support platform is provided at the bottom of the support slide rail 23. The second driving unit 22 is installed on the support platform, and its output end is connected to the slide plate 24. The second driving unit 22 can drive the slide plate 24 to slide up and down along the slide rail. Through the design of the slide rail structure, the steel drum can be kept stable during the lifting process; one side of the support slide rail 23 facing away from the slide plate 24 is connected to the output end of the first driving unit 20. The first driving unit 20 can drive the support slide rail 23 together with the slide plate 24, the chuck 21, and the second driving unit 22 to move. After the chuck 21 clamps the steel drum, the second driving unit 22 can perform the jacking action.

[0036] As Figure 1 and Figure 2 shown, the chuck 21 includes a positioning disk 211 and a first gear disk 212 fixedly connected to the positioning disk 211. The rotation axes of the positioning disk 211 and the first gear disk 212 coincide. The diameter of the first gear disk 212 is larger than that of the positioning disk 211. The bottom of the barrel and the barrel cover at both ends of the steel drum have a groove structure. The thickness of the positioning disk 211 is the same as the depth of the groove. During the clamping process, the positioning disk 211 extends into the groove. The end face of the positioning disk 211 abuts against the bottom of the groove, and the side wall of the positioning disk 211 is attached to the inner side face of the groove, thereby clamping the steel drum; the positioning disk 211 is fixedly attached to the first gear disk 212, and their rotation axes coincide. The first gear disk 212 rotates to drive the positioning disk 211 and the clamped steel drum to rotate. When the positioning disk 211 clamps the steel drum, the end faces of the bottom of the barrel and the barrel cover of the steel drum are further pressed against the surface of the first gear disk 212, further ensuring the stability of the clamping of the steel drum.

[0037] As Figure 1 and Figure 3 shown, the cutting disk 31 includes a cutter disk 311 and a second gear disk 312 fixedly connected to the cutter disk 311. The rotation axes of the cutter disk 311 and the second gear disk 312 coincide. The diameter of the second gear disk 312 is smaller than that of the cutter disk 311. The cutter disk 311 faces the cutting positions of the bottom of the barrel and the barrel cover of the steel drum. After the second driving unit 22 drives the chuck 21 to rise, the first gear disk 212 is meshed and connected with the second gear disk 312, and the cutter disk 311 and the positioning disk 211 approach to form a shearing structure. The cutter disk 311 is fixedly attached to the second gear disk 312, and their rotation axes coincide. The output end of the third driving unit is drivingly connected to the second gear disk 312. The third driving unit drives the second gear disk 312 to rotate and drives the first gear disk 212 to rotate, so that the steel drum rotates together with the chuck 21; the shearing structure formed by the cutter disk 311 and the positioning disk 211 shears off the bottom of the barrel and the barrel cover along the cutting position of the steel drum during the rotation of the steel drum.

[0038] As shown Figure 4 in the figure, the transverse cutting mechanism 4 includes a cutter 41, a fourth driving unit 42, a mounting plate 43, and a fifth driving unit 44. The fourth driving unit 42 is arranged on the mounting plate 43, and the cutter 41 is connected to the output end of the fourth driving unit 42. The fourth driving unit 42 can drive the cutter 41 to perform reciprocating linear motion. The fifth driving unit 44 is installed at the top of the frame 5, and the mounting plate 43 is connected to the output end of the fifth driving unit 44. The fifth driving unit 44 can drive the mounting plate 43 to move up and down. In this embodiment, the fourth driving unit 42 and the fifth driving unit 44 can adopt existing driving technologies, such as the way of cylinder driving or oil cylinder driving; the cutter 41 adopts a laser cutter. Before shearing the bottom and the lid of the steel drum, the transverse cutting mechanism 4 is first used to cut the side wall of the steel drum. Before the steel drum enters the clamping mechanism 2, the cutter 41 is at the top of the frame to avoid affecting the transfer of the steel drum by the sliding mechanism 1; when the steel drum is clamped and lifted, the fifth driving unit 44 drives the mounting plate to move downwards so that the cutter 41 approaches the steel drum. When the cutter 41 moves down to the position, the fourth driving unit 42 drives the cutter 41 to move along the side wall of the steel drum to cut open the side wall of the steel drum; after the cutting is completed, the fifth driving unit 44 drives the mounting plate 43 to move upwards so that the cutter 41 returns to the original position.

In this embodiment, the sixth driving unit adopts existing driving technologies, such as adopting a cylinder. The cylinder is installed at the bottom of the frame 5 and below the sliding plate 11, and the output end of the cylinder is connected to the sliding plate 11 to drive the sliding plate 11 to perform reciprocating linear motion, so that the two groups of bearing brackets 12 are alternately located below the clamping mechanism 2. There are two groups of alternately used bearing brackets 12 on the sliding plate 11 for placing two steel drums for cutting. When one of the steel drums is cut, the sixth driving unit drives the sliding plate 11 to move so that the cut steel drum is moved out of the clamping mechanism 2, and the steel drum on the other bearing bracket 12 is synchronously fed into the clamping mechanism 2. This way of linkage parallel feeding and discharging is beneficial to improving the processing efficiency. The bearing bracket 12 is composed of four rollers 121. The roller structure is convenient for manual picking and placing of the steel drum and for adjusting the position of the steel drum; at the same time, this structure is simple to install and disassemble, and is convenient for maintenance and replacement.
