Description

Technical Field

[0001] The present invention relates to the technical field of steel plate bevel cutting, and particularly to a semi-automatic circular steel plate blanking, bevel cutting and rapid centering device. Background Art

[0002] Steel plate bevel cutting refers to cutting a certain width of bevel at the edge position of the steel plate so that welders can operate inside the bevel. Its function is to improve the strength and quality of the welded joint, and at the same time facilitate later processing and maintenance. When beveling a steel plate, it is necessary to pay attention to selecting a suitable cutting tool to ensure the accuracy of the bevel. At the same time, attention should be paid to safety, wearing appropriate protective equipment, and following relevant operating procedures.

[0003] A Chinese invention patent with the publication number CN205519932U discloses a semi-automatic cutter for cutting circular plates, including: a cutter body, a traveling wheel is provided at the bottom of the cutter body, a supporting iron rod is installed at the bottom end of the cutter body, a limiting iron block is provided on the upper side of the supporting iron rod, a steel plate is arranged in the inner cavity of the supporting iron rod, a top cone is fixed to the lower side of the steel plate through a connecting member, and the top cone extends to the outside of the supporting iron rod. This semi-automatic cutter for cutting circular plates has a simple structure. By adding a top cone and a supporting iron rod, when a circular plate is placed into the device, the device can automatically cut the circular plate according to the support of the supporting iron rod and the drive of the top cone, filling the gap in circular plate cutters.

[0004] In addition, since manual blanking and beveling quality completely depend on the personal skills of the workers, the quality is difficult to control. Especially for circular and annular workpieces, it is difficult to cut circles manually, and the cutting surface quality is poor, seriously affecting the subsequent weld quality. The processing accuracy of the bevel is insufficient. For example, if the bevel angle deviation is too large or the surface roughness is too high, it will weaken the strength and load-bearing capacity of the welded joint, resulting in multiple reworks or even scrapping. At the same time, the inner diameters of different steel plates are different, and it is impossible to quickly position and effectively cut them. Therefore, the semi-automatic cutter for cutting circular plates disclosed in Chinese invention patent CN205519932U cannot adjust the cutting angle for steel plates of different sizes, nor can it clamp and position and automatically blank different sizes of steel plates.

[0046] It should be noted that the roller 40511 is made of rubber. The roller 40511 contacts the metal plate 102 to reduce the friction inside the metal plate 102, avoid hard contact with the metal plate 102, and reduce the stress inside the metal plate 102.

[0047] The following is the working process and principle of the above embodiment:

[0048] The initial state is as follows: spring 1 4035 is in an uncompressed state, spring 2 4056 is in an uncompressed state, torsion spring 1 4059 is not in a relaxed state, torsion spring 2 40512 is in a relaxed state, and the contact plate 4054 contacts the contact block 4058.

[0049] The working steps are as follows:

[0050] First, the operator controls the telescopic rod 2034 to start extending downward, causing the telescopic rod 2034 to drive the first spring 4035 to move downward synchronously, causing the first spring 4035 to drive the centering rod 4036 to move towards the central part of the metal plate 102, causing the centering rod 4036 to contact the platform for placing the metal plate 102 downward, causing the telescopic rod 2034 to drive the adjustment slider 4034 to move downward inside the second chute 4033, causing the telescopic rod 2034 to squeeze the first spring 4035 to contract downward, causing the adjustment slider 4034 to drive the top of the support rod 4037 to move downward synchronously, causing the support rod 4037 to drive the fixed block 4038 to move synchronously, causing the fixed block 4038 to drive the horizontally equal-length rod 4051 to move outward from the support plate 4031 inside the first chute 4032, causing the horizontally equal-length rod 4051 to drive the slide rod 4055 and the second spring 4056 to move synchronously, causing the second spring 4056 to drive the second slider 4053 to move towards the side close to the inner wall of the metal plate 102, causing the second slider 4053 to drive the roller 40511 to contact the inner wall of the metal plate 102, causing the roller 40511 to rotate under the contact action of the inner wall of the metal plate 102, causing the roller 40511 to drive the torsion spring two 40512 to rotate through the connecting plate 40510, causing the elastic force of the torsion spring two 40512 after rotation to always contact the inner wall of the metal plate 102. By driving the roller 40511 to contact the inner wall of the metal plate 102 through the adjustment slider 4034 and the horizontally equal-length rod 4051, the metal plate 102 with different inner diameters is fixed by contact, improving the stability of the metal plate 102 during the cutting process, and also realizing the centering of the metal plate 102 with different inner diameters, improving the efficiency of the centering of the metal plate 102. Subsequently, the roller 40511 drives the second slider 4053 to move under the contact action of the metal plate 102, causing the second slider 4053 to move inside the horizontally equal-length rod 4051 towards the side away from the contact block 4058, causing the second slider 4053 to drive the contact plate 4054 to move synchronously, causing the contact plate 4054 to no longer contact the contact block 4058, causing the torsion spring one 4059 to drive the top of the clamping block 4057 to rotate towards the side close to the metal plate 102, causing the clamping block 4057 to contact the upper surface of the metal plate 102 until the horizontally equal-length rod 4051 drives the clamping block 4057 to move to the outside of the metal plate 102, causing the clamping block 4057 to contact the outer wall of the metal plate 102 under the elastic action of the torsion spring one 4059, thereby causing the clamping block 4057 to clamp the outer wall of the metal plate 102. Subsequently, the first swing arm 201 rotates through the second swing arm 2031, and then the second swing arm 2031 drives the metal plate 102 to be discharged to the position where it needs to be discharged through the telescopic rod 2034. By the roller 40511 contacting the inside of the metal plate 102 and the clamping block 4057 clamping the outer wall of the metal plate 102, the stability of the metal plate 102 during the discharging process is improved.It also realizes the clamping and fixing of metal plates 102 with different diameters, improving the flexibility of the device.

[0051] When the clamping block 4057 abuts against the upper surface of the metal plate 102, at this time, the operator manually rotates the first adjusting rod 3031, so that the first adjusting rod 3031 drives the cutting nozzle 3032 to rotate synchronously. Through the reference scale plate 3034, the cutting nozzle 3032 is rotated to the position where it needs to rotate. Subsequently, the operator controls the cutting nozzle 3032 to start working through an external control device. Then, the operator controls the speed-regulating motor 2032 to rotate through an external control device, so that the speed-regulating motor 2032 drives the driving plate 2033 to rotate synchronously, so that the driving plate 2033 drives the telescopic rod 2034 to rotate synchronously, so that the telescopic rod 2034 drives the air pipe 3033 and the hinge block 2035 to rotate synchronously, so that the hinge block 2035 drives the horizontal adjusting rod 2036 to rotate synchronously, so that the horizontal adjusting rod 2036 drives the vertical adjusting rod 301 to rotate synchronously, so that the vertical adjusting rod 301 drives the scale plate 3034, the cutting nozzle 3032 and the first adjusting rod 3031 to rotate synchronously, so that the cutting nozzle 3032 cuts the metal plate 102. The inclination angle of the cutting nozzle 3032 can be adjusted through the first adjusting rod 3031 and the scale plate 3034, meeting the requirements for the cutting nozzle 3032 to cut metal plates 102 of various sizes and also meeting the effect of cutting different-angle grooves.
