DETAILED DESCRIPTION

[0015] The technical solution in the embodiments of the present application is to solve the problems of the above-mentioned background technology. The overall idea is as follows: by providing a shearing component and a welding component, the device of the present invention integrates the shearing and welding functions into one, thereby realizing the shearing and welding of steel strips on the steel coil production line, thereby effectively enhancing the efficiency of shearing and welding processing of steel coils.

[0016] Example: Refer to Figure 1 - Figure 3 As shown, an automatic shearing and welding machine of this embodiment includes a frame 1, a movable frame 2 is arranged in the middle of the inner side of the frame 1, and a cylinder 4 is arranged on the top of the movable frame 2. The cylinder 4 is fixedly installed in the middle of the top of the frame 1, and the cylinder 4 is used to drive the movable frame 2 to perform lifting and sliding movements; A shearing assembly is provided at the inner bottom of the frame 1, and the shearing assembly includes a shearing table 10 for supporting the steel plate 12. There are two sets of shearing tables 10, which are located at the inner bottom of the frame 1 and are fixedly installed on both sides of the frame 1 respectively; the shearing assembly also includes two sets of lower shearing blades 11 and two sets of upper shearing blades 9, and the two sets of lower shearing blades 11 are respectively installed on the side end surfaces of the two sets of shearing tables 10, and the two sets of upper shearing blades 9 are respectively arranged on both sides of the bottom end of the movable frame 2; A welding assembly is arranged in the middle of the inner side of the frame 1, and the welding assembly includes a laser welding gun 7. A driving assembly is arranged in the middle of the inner side of the movable frame 2, and the driving assembly is used to drive the laser welding gun 7 to slide horizontally. The driving assembly includes a slide rail 5 and an electric slider 6.

[0017] The movable frame 2 includes a welding platform 21 and a top plate 22 . The welding platform 21 is located at the bottom of the movable frame 2 . A tool holder 8 is installed in the middle of the bottom end of the welding platform 21 . The upper shear blades 9 are fixedly installed at both ends of the tool holder 8 .

[0018] The top plate 22 is located on the top of the movable frame 2 , and the output end of the oil cylinder 4 passes through the frame 1 and is fixedly connected to the top plate 22 .

[0019] In some examples, limit guide rods 3 are provided at both ends of the inner side of the frame 1, and the limit guide rods 3 are respectively located in the middle of the two ends of the movable frame 2, and are slidably connected to the movable frame 2. The limit guide rods 3 mainly play a limiting role, thereby improving the stability of the movable frame 2 during the lifting and sliding movement, so that the shearing assembly can perform stable shearing processing on the steel plate 12.

[0020] In some examples, the slide rail 5 is fixedly installed in the inner middle part of the movable frame 2, the laser welding gun 7 is fixedly installed on the side end surface of the electric slider 6, and the electric slider 6 is slidably installed on the slide rail 5. The electric slider 6 slides on the slide rail 5, driving the laser welding gun 7 to slide in the horizontal direction.

[0021] In some examples, the laser welding gun 7 is located at the middle of the upper end of the welding table 21 .

[0022] In some examples, the upper shearing blade 9 is configured as an inclined structure and is located at the upper end of the lower shearing blade 11, which can enhance the stability of shearing the steel coil.

[0023] The working principle of the present invention is: When the steel strip needs to be sheared and welded, firstly, the tail of the previous steel strip is pulled to the shearing table 10 on the right side by the existing traction equipment, and the steel strip is clamped and fixed by the existing clamping mechanism. In particular, the edge position of the steel strip needs to be paid attention to, and should not exceed half of the width of the shearing cut; Then the coil head edge of the newly-loaded steel strip is pulled onto the shearing table 10 on the left side and is also clamped and fixed by the clamping mechanism. The edge of the steel plate 12 after the newly-loaded steel strip is unrolled should not exceed half of the width of the shearing opening. After the steel strips to be sheared on both sides are all fixed, the shearing assembly is started at this time. First, the oil cylinder 4 is started, and the movable frame 2 is pushed by the oil cylinder 4. Under the guidance of the two sets of limit guide rods 3, the upper shearing blade 9 will approach the lower shearing blade 11 to achieve the cutting work on the edge of the steel strip. When the upper shearing blade 9 exceeds the lower shearing blade 11, the edges of the steel strips on both sides are completely cut off; At this time, the oil cylinder 4 continues to push the movable frame 2 downward until the table surface of the welding table 21 is flush with the table surfaces of the shearing tables 10 on both sides, thereby forming a welding plane.

[0024] Then, the steel strips on both sides are clamped by the clamping mechanism and simultaneously moved toward the middle, so that the cuts of the steel strips on both sides are closed in the middle, just coinciding with the trajectory of the laser welding gun 7 .

[0025] At this time, the driving unit of the electric slider 6 can be started to drive the electric slider 6 to slide horizontally on the slide rail 5. During the sliding process, the laser welding gun 7 is started synchronously to achieve welding processing of the connection gap between the two sets of steel strips.

[0026] After the steel strips on both sides are welded together, the clamping mechanisms on both sides can be loosened to allow the steel strips to pass freely. Under the traction of the traction equipment, the steel strips are driven to slide out of the welding table 21 until the steel strips reach the end of the tail again and leave the shearing assembly. At this time, the movable frame 2 can be raised to the initial position to prepare for the next shearing and welding operation.

[0027] Through the above structure, the present invention can automatically complete the above actions under the control of the automatic control system, and repeat the above operations to realize the automatic shearing and welding of steel strips on the steel strip production line.

[0028] During the application of the present invention, the traction equipment and the clamping mechanism are both existing mature technologies, so no detailed description is given.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
