The welding equipment welds the tail of the previous steel coil and the head of the next steel coil to improve production efficiency. The tail of the steel coil and the head of the next steel coil are sheared by the transverse shearing equipment. There is a certain distance from the welding area of ​​the welding equipment. In order to meet the welding requirements of the welding equipment, it is necessary to accurately deliver the tail of the previous coil and the head of the next coil to the welding area for the convenience of the welder. In order to meet the above requirements, there must be a pressure plate feeding device in front and behind the welding equipment to meet the welding process requirements of the production line.

[0003] In the prior art, the pressure plate belt feeding device of the welding machine equipment on the unit production line adopts the method that the head or tail of the strip is fixedly clamped by the pressure plate and the lower platform respectively, and the hydraulic cylinder pushes the lower platform and the pressure plate device to move the head or tail of the strip to the welding area. The pressure plate cannot press down and feed the strip to jointly control the feed amount of the head or tail of the strip, and the feeding accuracy is low. This pressure plate belt feeding method requires high position accuracy of the stop position of the head or tail of the strip after transverse shearing, so as to ensure the accurate position of the strip to the welding area, and has high requirements for the position control of the head or tail of the production line strip.

[0030] like Figure 1-2 As shown, a high-precision pressure plate tape feeding device for welding provided by an embodiment of the present invention comprises: a frame 4, a first oil cylinder 9, a movable frame 10, two second oil cylinders 7, a sliding seat 12, an upper roller component 11, a lower roller component 2 and a pressure plate component 3. The first oil cylinder 9 is arranged vertically, and the fixed end is fixedly connected to the frame 4. The movable frame 10 is arranged below the first oil cylinder 9 and is fixedly connected to the telescopic end of the first oil cylinder 9. The two second oil cylinders 7 are symmetrically arranged on both sides of the first oil cylinder 9 with the first oil cylinder 9 as the center, and the fixed end is connected to the movable frame 10. The sliding seat 12 is fixedly connected to the telescopic end of the second oil cylinder 7 and is slidably connected to the movable frame 10. The upper roller component 11 is arranged below the movable frame 10 and is connected to the sliding seat 12. The lower roller component 2 is arranged below the upper roller component 11 and is connected to the frame 4. The pressure plate component 3 is arranged on one side of the upper roller component 11, and the upper end is connected to the movable frame 10. In this embodiment, the first oil cylinder 9, the second oil cylinder 7 and the pressure plate component are respectively connected to the power supply through their respective control buttons.

[0031] Usage and working principle: After the steel coil strip is sheared and aligned, the head or tail of the strip moves to a certain position on both sides of the welding area, and the control button of the first oil cylinder 9 is turned on. The telescopic end of one oil cylinder 9 extends to drive the moving frame 10 and the two second oil cylinders 7 to move downward synchronously, and the sliding seat 12 fixedly connected thereto moves downward, driving the upper roller component 11 to move downward synchronously, and the pressure plate component 3 moves downward with the moving frame 10 until the head or tail of the strip is flattened, and detects whether the distance between the head and the tail of the strip meets the welding process requirements (lap welding requires a certain amount of overlap between the head and the tail of the strip, and butt welding requires a certain distance gap between the head and the tail of the strip). When the stop position of the head and the tail of the strip does not meet the process requirements, the control button of the second oil cylinder 7 is turned on, and the telescopic ends of the two second oil cylinders 7 installed on the moving frame 10 extend to cause the sliding seat 12 fixedly connected thereto to move downward, driving the upper roller component 11 to move downward and to be connected to the lower roller component installed on the frame 4. 2 clamps the plate strip. At the same time, due to the extension of the second oil cylinder 7, the first oil cylinder 9 retracts a certain distance, so that a small gap is generated between the movable frame 10 and the plate strip, and the pressure plate component 3 is lifted and no longer contacts the plate strip. At this time, the lower roller component 2 is started to rotate until the clamped plate strip is fed or retreated to meet the welding process requirements. Then the lower roller component 2 is operated to stop rotating. Subsequently, the telescopic end of the second oil cylinder 7 is shortened, and the upper roller component 11 is separated from the lower roller component 2. The first oil cylinder 9 resumes the maximum extension distance to make the movable frame 10 clamp the plate strip, and the pressure plate component 3 installed on the movable frame 10 is started until the belt head or belt tail is clamped. After the above operations are completed, the plate strip is ready for welding. The sliding seat 12 plays a guiding and limiting role. The sliding seat 12 cooperates with the movable frame 10 along the vertical sliding, so that the sliding seat 12 can only move up and down vertically, so that the upper roller component 11 fixed thereto moves up and down vertically without position displacement.

[0032] The present invention adopts a pressure plate device to press down and then clamp the plate strip, and can adjust the plate strip feed amount with high precision. The first oil cylinder is extended to press the pressure plate device down, and the second oil cylinder is extended to clamp the upper and lower roller parts of the plate strip. At the same time, the double second oil cylinder reacts with the first oil cylinder to shorten its telescopic end, which can produce a small gap between the pressure plate device and the plate surface. The lower roller component rotates to feed or retreat the clamped plate strip, thereby improving the accuracy of the welding position.

[0033] like Figure 3 As shown, a high-precision pressure plate tape feeding device for welding provided by an embodiment of the present invention also includes: a plurality of guide pillars 8 and a pressure plate frame 6. The plurality of guide pillars 8 are arranged parallel to the axial direction of the first oil cylinder 9, and the lower ends are fixedly connected to the movable frame 10. The pressure plate frame 6 is fixedly installed on the frame 4. The pressure plate frame 6 has a plurality of through holes along the axial direction parallel to the frame 4. The guide pillars 8 respectively pass through the through holes and slide with the pressure plate frame 6 along the axial direction.

[0034] In this embodiment, there are two guide columns 8 and two through holes, which are symmetrically arranged on the left and right sides of the first oil cylinder 9. The guide columns 8 play a guiding and limiting role. The guide columns 8 and the pressure plate frame 6 slide together along the axial direction, so that the guide columns 8 can only move vertically up and down, thereby making the movable frame 10 fixed thereto move vertically up and down without causing position deviation.

[0035] like Figure 4 As shown, a high-precision pressure plate feeding device for welding provided by an embodiment of the present invention also includes a welding platform 1, which is fixed to a frame 4, and the upper end surface of the welding platform 1 is flush with the upper surface of the lower roller component 2, and the plate and strip are placed on the welding platform 1 for welding and transmission.

[0036] Optionally, a reduction motor 5 is also included. The reduction motor 5 is installed on the frame 4, and the output end is connected to the roller shaft of the lower roller component 2. The reduction motor 5 is used to drive the lower roller component 2 to rotate, and the reduction motor 5 is connected to a power source.

[0037] Optionally, the pressure plate component 3 is a piano-key type pressure plate, and the airbag of the pressure plate device can compress the plate strip for a second time after being inflated, so that the plate strip can be compressed better when the shape of the plate strip is not good.

[0038] Optionally, the sliding seat 12 has a longitudinal guide groove, and the moving frame 10 has a boss, and the boss cooperates with the longitudinal guide groove, so that the sliding seat 12 and the moving frame 10 can slide and cooperate with each other along the axial direction.

[0039] Usage method and working principle: The head or tail of the steel coil is moved to a position on both sides of the welding area on the welding platform 1 after being sheared horizontally, and the telescopic end of the first oil cylinder 9 is extended to drive the moving frame 10 and the two second oil cylinders 7 to move downward synchronously. At the same time, the guide column 8 moves downward along the through hole of the pressure plate frame 6, and the sliding seat 12 fixedly connected to the second oil cylinder 7 moves downward, driving the upper roller component 11 to move downward synchronously, and the pressure plate component 3 moves downward with the moving frame 10 until the head or tail of the strip is flattened, and detects whether the distance between the head and the tail of the strip meets the welding process requirements (lap welding requires a certain amount of overlap between the head and the tail of the strip, and butt welding requires a certain distance gap between the head and the tail of the strip). When the stop position of the head and the tail of the strip does not meet the process requirements, the telescopic ends of the two second oil cylinders 7 installed on the moving frame 10 are extended to cause the sliding seat 12 fixedly connected thereto to move downward, driving the upper roller component 11 to move downward and clamp the strip with the lower roller component 2 installed on the frame 4, reducing The high-speed motor 5 drives the lower roller component 2 to rotate. At the same time, due to the extension of the second oil cylinder 7, the first oil cylinder 9 retracts a certain distance, so that a small gap is generated between the movable frame 10 and the plate strip, and the pressure plate component 3 is lifted and no longer contacts the plate strip. At this time, the lower roller component 2 is started to rotate until the clamped plate strip is fed or retreated to meet the welding process requirements. Then the operation makes the lower roller component 2 no longer rotate. Subsequently, the telescopic end of the second oil cylinder 7 is shortened, and the upper roller component 11 is separated from the lower roller component 2. The first oil cylinder 9 resumes the maximum extension distance to make the movable frame 10 press the plate strip. The pressure plate component 3 installed on the movable frame 10 is started again until the belt head or tail is pressed. After the above operations are completed, the plate strip is ready for welding. The sliding seat 12 plays a guiding and limiting role. The sliding seat 12 cooperates with the movable frame 10 along the vertical sliding, so that the sliding seat 12 can only move up and down vertically, so that the upper roller component 11 fixed thereto moves up and down vertically without position displacement.

[0040] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
