Description

Technical Field

[0001] The invention relates to the technical field of cutting device technology, and in particular to a high-precision fast cutting device for flat welding flange processing. Background Art

[0002] Flat welding flange refers to a flange that is connected to a container or pipeline by a fillet weld. It is an arbitrary flange. During design, it is checked as an integral or loose flange according to the degree of integrity of the connection between the flange ring and the straight section. Flat welding flanges are widely used in the connection of medium and low pressure containers and pipelines. The production process of large-diameter flat welding flanges is generally to cut the steel plate into strips first, then cut the steel strip of the corresponding length, and finally bend it into a ring shape, then weld the two ends of the steel strip, and finally grind it into shape.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0020] Embodiment, according to Figure 1-Figure 12 ,like Figure 1 In the embodiment of the present invention, the high-precision fast cutting device for flat welding flange processing includes a frame 1, a roller conveyor 2 fixedly installed at one end of the frame 1, a cam punch 5 and a punching seat 8 arranged directly below the cam punch 5, the frame 1 is provided with an adjustment handle 101 for adjusting the spacing of the roller conveyor 2, an electric push rod 102 is fixedly installed on one side of the frame 1, a tooth plate 103 is slidably installed on one side of the frame 1, and the tooth plate 103 is fixedly installed on the telescopic end of the electric push rod 102, and also includes: A fixed length component 3 installed at one end of the frame 1 away from the roller conveyor 2 for adjusting the shear length of the flange steel belt; A trigger assembly 4 is installed on one side of the frame 1 to cooperate with the fixed length assembly 3 to cut the flange steel strip. When the steel strip is conveyed to a certain length, the fixed length assembly 3 drives the trigger assembly 4, and then the cam punch 5 punches downward to drive the punch seat 8 to shear the cut steel strip; A cutting assembly 6 installed on the frame 1 for cutting the raw material plate into strips, wherein the steel plate can be cut into a plurality of steel strips by the cutting assembly 6 during the steel plate conveying process; A plurality of connection components 7 mounted on the cutting component 6 for cutting and shearing linkage adjustment; A plurality of shearing components 9 are arranged in the punching seat 8 for cooperating with the cam punching machine 5 to shear the flange steel strip. In the process of adjusting the cutting component 6, the shearing component 9 is driven by the connecting component 7 to adjust in linkage, so as to ensure the cutting and shearing of steel strips of different widths.

[0021] like Figure 2In the embodiment, the fixed length component 3 includes a guide plate 301, a push rod 302 and a driving rod 303. The guide plate 301 is fixedly mounted on the frame 1, the push rod 302 is slidably mounted on the guide plate 301, a slider is rotatably mounted on the driving rod 303 and the driving rod 303 is rotatably mounted on the guide plate 301 through the slider, a positioning bolt for positioning the driving rod 303 is threadedly mounted on the driving rod 303, a pulley 304 is rotatably mounted on one end of the push rod 302, a first spring 305 is fixedly mounted between the push rod 302 and the guide plate 301, a plurality of longitudinal first sliding grooves 306 are provided on the push rod 302, and a first convex column 307 slidably matched with the first sliding groove 306 is provided on the driving rod 303, wherein the steel plate is transported to a certain length by the roller conveyor 2, and the steel plate pushes the driving The rod 303 rotates, and the driving rod 303 rotates. Through the sliding cooperation of the first protrusion 307 and the vertically arranged first slide groove 306, the push rod 302 is driven to slide in the opposite direction of the steel plate conveying direction. At the same time, the trigger assembly 4 is driven by the pulley 304 to cooperate with the cam punch 5 to shear the steel strip. After the action is completed, the elastic effect of the first spring 305 is used to drive the push rod 302 and the driving rod 303 to return to their original positions to achieve the purpose of fixed-length shearing. If it is necessary to adjust the shearing length of the steel strip, it is only necessary to use the sliding effect of the slider on the driving rod 303 and the guide plate 301 to adjust the position of the driving rod 303, and then make the protrusion stuck in the corresponding first slide groove 306, so that the distance between the driving rod 303 and the punching seat 8 changes, and the purpose of adjusting the shearing length of the steel strip is achieved.

[0022] like Figure 3 In the embodiment, the trigger assembly 4 includes a column 401 and a sleeve 402 movably mounted on the column 401, a second spring 403 is fixedly installed between the sleeve 402 and the column 401, a support plate is formed in a horizontal manner on the top of the sleeve 402, and a placement tube 404 is provided on the top of one end of the support plate, and a plurality of gaskets 405 are stacked and placed in the placement tube 404, such as Figure 1 In the embodiment, the length of the support plate integrally formed on the top of the sleeve 402 is equal to the length of the line connecting the center of the sleeve 402 and the center of the punching head of the cam punch 5. When the steel belt drives the push rod 302 to slide in the opposite direction of the steel plate conveying direction, the pulley 304 pushes the support plate to rotate a certain angle until the placement cylinder 404 is located directly below the cam punch 5. The cam punch 5 presses downward through the gasket 405 to press the sleeve 402 downward to drive the punching seat 8 to punch and shear the steel belt. After the action is completed, the placement cylinder 404 is driven to return to its original position through the elastic action of the second spring 403. By increasing or decreasing the number of gaskets 405 stacked in the placement cylinder 404, the fixed-length component 3 is cooperated to achieve the purpose of punching and shearing steel plates of different thicknesses.

[0023] like Figure 4In the embodiment, the cutting assembly 6 includes an adjusting roller 601, a first slide 602 and a gear roller 603. The adjusting roller 601 and the gear roller 603 are both rotatably mounted on the frame 1. One end of the shaft of the adjusting roller 601 is fixedly mounted with a first gear 604 meshing with the gear plate 103. Two slide bars are arranged in the frame 1. The first slide 602 is provided with a plurality of saw blades 605, which are all slidably mounted on the slide bars. The gear roller 603 is provided with a plurality of second slide grooves 607. One end of the first slide 602 is provided with a second protrusion 608 slidably matched with the second slide groove 607. A connecting rod 606 is fixedly welded on the first slide 602. The steel plate is conveyed by a roller conveyor. During the conveying process, the gear roller 603 is driven to rotate by an external driving motor, and the saw blade 605 is driven to rotate by the meshing action of the gear roller 603 and the gear sleeve 609, so that the complete steel plate can be cut into multiple steel strips. If it is necessary to adjust the width of the cut steel strip, the electric push rod 102 is controlled to extend and retract, and the adjusting roller 601 is driven to rotate by the meshing action of the gear plate 103 and the first gear 604. The adjusting roller 601 rotates and drives the first slide seat 602 to move away from or closer to each other through the sliding cooperation action of the second slide groove 607 and the second protrusion 608, and drives the saw blade 605 to move away from or closer to each other, so as to achieve the purpose of adjusting the spacing between the saw blades 605, and finally achieve the purpose of adjusting the cutting width of the steel strip.

[0024] like Figure 5 In the figure, a plurality of second slide grooves 607 are equally divided into mirror images on the adjusting roller 601, and the plurality of second slide grooves 607 are all arranged in an arc shape and the curvature increases successively. Among them, since the slide grooves are in an arc shape, the rotation of the adjusting roller 601 will drive the first slide 602 to slide through the sliding cooperation with the convex column, and since the curvature increases successively, the distance between adjacent slides will increase or decrease, thereby achieving the purpose of adjusting the distance between the saw blades 605.

[0025] like Figure 6 In the figure, a tooth sleeve 609 is fixedly installed at the center of the saw blade 605, and the saw blade 605 is meshedly connected to the tooth roller 603 through the tooth sleeve 609. One end of the connecting rod 606 is rotatably sleeved on the tooth sleeve 609. During the rotation of the tooth roller 603, the saw blade 605 is driven to rotate on the connecting rod 606 through the meshing action of the tooth roller 603 and the tooth sleeve 609, and the saw blade 605 is driven to slide axially on the tooth roller 603 by the connecting rod 606 without interfering with the rotation of the saw blade 605.

[0026] like Figure 7-9In the figure, the connecting component 7 includes a second slide 701 and a first spring telescopic rod 702. The first spring telescopic rod 702 is provided with two and is movably inserted at both ends of the second slide 701 respectively. The other end of the first spring telescopic rod 702 is fixedly installed on the first slide 602, and a second spring telescopic rod 703 is fixedly installed on the top of the second slide 701. The sliding action of the first slide 602 drives the shearing component 9 to move through the limiting action of the first spring 305 telescopic rod and the second slide 701, and the elastic action of the first spring 305 telescopic rod makes the shearing component 9 always located at the midpoint of the line connecting the two saw blades 605. During the stamping and shearing process of the stamping seat 8, the telescopic action of the second spring 403 telescopic rod will not cause the shearing component 9 to interfere with the stamping seat 8 like a rigid connection.

[0027] like Figure 10-12 In the embodiment, the shearing assembly 9 includes a mounting frame 901 and a V-shaped punching cutter head 902. The two sides of the punching cutter head 902 have different lengths and are arranged at an angle that deviates from the radial line of the saw blade 605. The second spring telescopic rod 703 penetrates the punching seat 8 and is fixedly connected to the mounting frame 901. The punching cutter head 902 is fixedly installed on the mounting frame 901. Two connecting rods 903 are rotatably installed at the bottom of the punching cutter head 902. The two connecting rods 903 are rotatably connected to each other and are in a scissor shape. One end of the connecting rod 903 is integrally formed with The tooth head 904, the mounting frame 901 is provided with an arc groove for limiting the connecting rod 903, the mounting frame 901 is slidably mounted with a first tooth ring 905 and a second tooth ring 906, the mounting frame 901 is rotatably mounted with a second gear 907, the second gear 907 is arranged between the first tooth ring 905 and the second tooth ring 906 and is meshed with the first tooth ring 905 and the second tooth ring 906 at the same time, the inner wall of the stamping seat 8 is provided with a tooth surface and the second tooth ring 906 is meshed with the tooth surface of the stamping seat 8, as shown in FIG. Fig.10 and Fig.11In the figure, the bottom and inner circumference of the first tooth ring 905 are provided with teeth, and the top, inner circumference and outer circumference of the second tooth ring 906 are provided with teeth. In the process of stamping the steel strip by the stamping seat 8, the "V"-shaped stamping tool head 902 will shear a "V"-shaped head and a notch at both ends of the steel strip. In the later bending and welding process of the steel strip, the "V"-shaped butt joint area is larger than the flat butt joint area, which effectively improves the welding strength, thereby improving the overall strength of the flange after forming. At the same time, the length of both sides of the stamping tool head 902 is set according to the deviation angle of the saw blade 605 diameter line, which can make up for the deformation error after the steel strip is bent, and is convenient for the first bending of the steel strip. Tail docking, when adjusting the width of the cut steel strip, the cutting component 6 drives the mounting frame 901 to move through the connecting component 7, and the movement of the mounting frame 901 drives the second gear ring 906 to slide in a circle through the meshing action of the second gear ring 906 and the inner wall tooth surface of the punching seat 8. At the same time, the second gear ring 906 drives the first gear ring 905 to slide in a circle in the opposite direction through the second gear 907, and then the meshing action of the tooth head 904 with the first gear ring 905 and the second gear ring 906 drives the opening and closing angles of both sides of the shearing head to change (under the limiting action of the arc groove on the mounting frame 901), so as to adapt to the cutting of steel strips of different widths.

[0028] The specific working principle is that the steel plate raw materials required for the production of flat welding flanges are transported through the roller conveyor 2, and the adjustment handle 101 can be adjusted for different thicknesses of steel plates (the adjustment handle 101 changes the spacing between the upper and lower rollers of the roller conveyor 2, which belongs to the known technology). During the conveying of the plate through the roller conveyor 2, the toothed roller 603 is driven to rotate by an external driving motor, and the saw blade 605 is driven to rotate through the meshing action of the toothed roller 603 and the toothed sleeve 609 to cut the complete steel plate into multiple steel strips. The steel strips are transported to a certain length through the roller conveyor 2, and the steel plate pushes the driving rod 303 to rotate, and the driving rod 303 rotates the belt The movable push rod 302 slides in the opposite direction of the steel plate conveying direction, and the steel belt pushes the support plate to rotate a certain angle through the pulley 304 until the placement cylinder 404 is located directly below the cam punch 5. The cam punch 5 punches downward through the gasket 405 to press the sleeve 402 downward. By increasing or decreasing the number of gaskets 405 stacked in the placement cylinder 404, the fixed-length component 3 is used to achieve the purpose of intermittent punching and shearing of steel plates of different thicknesses. After the shearing action is completed, the elastic action of the first spring 305 is used to drive the push rod 302 and the driving rod 303 to return to their positions, and the elastic action of the second spring 403 is used to drive the placement cylinder 404 to return to its position; If it is necessary to adjust the flange thickness, diameter and ring width (i.e., adjust the steel plate thickness, steel strip length and steel strip width) to meet different production needs, if it is necessary to adjust the steel strip shearing length, it is only necessary to use the sliding action of the slider on the driving rod 303 and the guide plate 301 to adjust the position of the driving rod 303, and then make the boss stuck in the corresponding first slide groove 306, so that the distance between the driving rod 303 and the stamping seat 8 changes, and the purpose of adjusting the steel strip shearing length is achieved. If it is necessary to adjust the width of the cut steel strip, the electric push rod 102 is controlled to retract and the adjusting roller 601 is driven to rotate through the meshing action of the toothed plate 103 and the first gear 604. The adjusting roller 601 rotates and drives the first slide seat 602 to move away from or approach each other through the sliding cooperation action of the second slide groove 607 and the second boss 608, and drives the saw blade 605 to move away from or approach each other (because the slide groove is arc-shaped, the adjusting roller 601 is adjusted to move away from or approach each other). The rotation of 601 will drive the first slide 602 to slide through the sliding cooperation with the convex column, and since the curvature increases successively, the distance between adjacent slides will increase or decrease), thereby achieving the purpose of adjusting the distance between the saw blades 605, and finally achieving the purpose of adjusting the cutting width of the steel strip. If the width of the cut steel strip needs to be adjusted, the cutting component 6 drives the mounting frame 901 to move through the connecting component 7, and the movement of the mounting frame 901 drives the second gear ring 906 to slide in a circular manner through the meshing action of the second gear ring 906 and the inner wall tooth surface of the punching seat 8. At the same time, the second gear ring 906 drives the first gear ring 905 to slide in a circular manner in the opposite direction through the second gear 907, and then utilizes the meshing action of the tooth head 904 with the first gear ring 905 and the second gear ring 906 to drive the opening and closing angles of both sides of the shearing head to change (under the limiting action of the arc groove on the mounting frame 901), thereby adapting to the cutting of steel strips of different widths.
