Description

Technical Field

[0001] This application relates to the field of stainless steel strip production technology, specifically to a precision stainless steel strip shearing device. Background Technology

[0002] Stainless steel strip is a long, thin sheet material made of stainless steel, which has excellent corrosion resistance, heat resistance and mechanical strength.

[0003] An existing patent (publication number: CN119897514A) discloses a precision stainless steel strip shearing device, including a cutting assembly. A transmission assembly is fixedly connected to the top of the cutting assembly, and a moving assembly is fixedly connected to the top of the transmission assembly. A machine tool assembly is movably sleeved on the inner side of the moving assembly. The cutting assembly includes a cutter housing. A generator is bolted to one side of the cutter housing, and a circuit breaker assembly is fixedly connected to the bottom of the generator. A connecting piece is electrically connected to the bottom of one side of the cutter housing. A temperature-sensitive circuit breaker is electrically connected to the front of the connecting piece, and a fan assembly is electrically connected to the bottom of the temperature-sensitive circuit breaker. One end of the fan assembly is fixedly sleeved on the bottom of the connecting piece. A cutter shaft is rotatably sleeved on the other side of the cutter housing, and a blade is fixedly connected to one end of the cutter shaft. This facilitates the collection of debris generated during the shearing of stainless steel, preventing it from splashing or clogging the cutter connection gap.

[0004] The aforementioned shearing equipment cannot achieve automated fixed-length cutting during use, relies heavily on manual labor, has low operating efficiency, and does not limit the strip material during the shearing process, making it prone to deviation and affecting the inspection quality. There is room for improvement. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a precision stainless steel strip shearing device that can perform automated fixed-length strip shearing operations, saving manpower, improving work efficiency, and limiting the strip during the shearing process to prevent easy strip deviation and improve shearing quality, thus solving the problems mentioned in the background technology.

[0006] To achieve the above objectives, this application provides the following technical solution: a precision stainless steel strip shearing device, comprising a base, a shearing table centrally disposed inside the base, a first support fixedly connected to the upper surface of the shearing table, a hydraulic cylinder fixedly connected to the upper surface of the first support, a cutter fixedly connected to the output end of the hydraulic cylinder, a first conveyor belt and a second conveyor belt disposed inside the base, the first conveyor belt and the second conveyor belt being symmetrically arranged based on the first support, a second support fixedly connected to the upper surface of the base, a lead screw rotatably connected inside the second support, and the lead screw having a thread on its outer circumferential surface. The system is connected to two threaded tubes, each with a limiting plate fixedly connected to its bottom via a connecting plate. The base has two T-slots at its top, each with a T-shaped slider slidably connected inside. A third bracket is fixedly connected to the upper surface of the two T-shaped sliders, and a laser sensor is fixedly connected inside the third bracket. A first shearing roller is rotatably connected inside the shearing table, and equidistantly arranged annular blades are fixedly connected to the outer circumferential surface of the first shearing roller. A second shearing roller is rotatably connected inside the shearing table, with the cutting edge of the annular blade contacting the outer circumferential surface of the second shearing roller.

[0007] The above solution aims to improve the efficiency of strip shearing operations, ensure the quality of cutting operations, and save manpower. By setting up a first conveyor belt, a second conveyor belt, a hydraulic cylinder, a cutter, and a movable laser sensor, the strip can be assisted in conveying and the cutting length of the strip can be detected. This automatically completes the fixed-length shearing operation of the strip, saving manpower and improving work efficiency. When the lead screw rotates, it drives the limiting plate to move under the action of the threaded tube. This can limit the two sides of the strip during the shearing process of strips of different sizes, preventing the strip from easily deviating and improving the shearing quality.

[0008] Furthermore, the first bracket has two guide grooves inside, and the two ends of the cutter are slidably connected to the first bracket through the guide grooves.

[0009] With the above solution, when the hydraulic cylinder drives the cutter to perform the shearing action, the guide groove can prevent the cutter from deviating or shaking during the movement, ensuring that the cutter always presses down vertically along the predetermined trajectory, thereby ensuring the stability and quality of the shearing process, and making the cut of the stainless steel strip neater and more precise.

[0010] Furthermore, the lead screw is a bidirectional threaded rod, and handwheels are fixedly connected to both ends of the lead screw.

[0011] Through the above scheme, the characteristics of the bidirectional threaded rod allow the threaded tube to move in opposite directions simultaneously when the handwheel is rotated, thereby driving the limit plate to adjust the spacing synchronously. This allows operators to quickly and accurately adjust the position of the limit plate according to stainless steel strips of different widths, achieving flexible adjustment of the limit function and improving the versatility and ease of operation of the equipment.

[0012] Furthermore, both ends of the second bracket are fixedly connected to crossbars, and the upper surface of each limiting plate is fixedly connected to two collars through a connecting plate, and the collars are slidably sleeved with the crossbars respectively.

[0013] Through the above scheme, the cooperation of the crossbar and the collar provides additional guidance and support for the movement of the limiting plate, making the limiting plate more stable during movement and avoiding the problem of inaccurate limiting due to unstable movement. At the same time, this structure enhances the stability of the limiting plate, ensuring that the limiting plate can reliably play its limiting role during the conveying of stainless steel strip.

[0014] Furthermore, two scales are fixedly connected to the outer surface of the base, and the cutting position of the cutter corresponds to the zero mark of the scales.

[0015] The above method provides operators with an intuitive length reference, allowing them to quickly and accurately determine the position of the laser sensor and adjust the cutting position of the stainless steel strip.

[0016] Furthermore, a servo motor is provided on one side of the base, and the output end of the servo motor is fixedly connected to one end of the second shearing roller. A sprocket is fixedly connected to one end of both the first and second shearing rollers, and a chain is driven between the two sprockets.

[0017] Through the above scheme, the servo motor has the characteristics of high precision and high response speed, which can accurately control the speed and position of the second shearing roller. The first shearing roller is rotated synchronously through the sprocket and chain drive, so as to realize the stable shearing of stainless steel strip by the ring blade.

[0018] Furthermore, the top of the shearing table is fixedly connected to two positioning plates by bolts. The bottom of the positioning plates and the top of the shearing table are both provided with semi-circular grooves. The first shearing roller is rotatably connected to the positioning plates and the shearing table through the semi-circular grooves.

[0019] The above solution makes the installation and disassembly of the first shearing roller more convenient, facilitating its removal, replacement, and maintenance.

[0020] Furthermore, two limiting rings are fixedly sleeved on the outer circumferential surface of the first shearing roller, and the side of the limiting rings near the shearing table is in contact with the outer surface of the shearing table.

[0021] Through the above scheme, the function of the limiting ring is to axially limit the first shearing roller, prevent it from moving axially during operation, ensure the precise fit between the annular blade and the second shearing roller, and thus improve the stability and accuracy of shearing.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This precision stainless steel strip shearing equipment, equipped with a first conveyor belt, a second conveyor belt, a hydraulic cylinder, a cutter, and a movable laser sensor, assists in the conveying of the strip and detects the cutting length. It automatically completes the fixed-length shearing operation, saving manpower and improving work efficiency. When the lead screw rotates, it drives the limit plate to move under the action of the threaded tube, which can limit the two sides of the strip during the shearing process of strips of different sizes, preventing the strip from easily deviating and improving the shearing quality. By setting a second shearing roller, a detachable first shearing roller, and equidistantly arranged annular blades, it can complete the longitudinal shearing operation of the strip as needed, improving the practicality of the shearing equipment.

[0035] Please see Figure 1 and Figure 4 The first support 3 has two guide grooves 28 inside. The two ends of the cutter 5 are slidably connected to the first support 3 through the guide grooves 28. When the hydraulic cylinder 4 drives the cutter 5 to perform the cutting action, the guide grooves 28 can prevent the cutter 5 from deviating or shaking during the movement, ensuring that the cutter 5 always presses down vertically along the predetermined trajectory, thereby ensuring the stability and cutting quality of the cutting process, and making the cut of the stainless steel strip more neat and precise.

[0036] Please see Figure 1The lead screw 9 is a bidirectional threaded rod, and both ends of the lead screw 9 are fixedly connected to handwheels 12. The bidirectional threaded rod characteristic allows the threaded tube 10 to move in opposite directions simultaneously when the handwheel 12 is rotated, thereby driving the limit plate 11 to adjust the spacing synchronously. This makes it convenient for operators to quickly and accurately adjust the position of the limit plate 11 according to the stainless steel strip of different widths, realize the flexible adjustment of the limit function, and improve the versatility and ease of operation of the equipment.

At the same time, this structure enhances the stability of the limiting plate 11 and ensures that the limiting plate 11 can reliably play its limiting role during the conveying of stainless steel strip.

[0038] Please see Figure 1 and Figure 2 Two scales 19 are fixedly connected to the outer surface of the base 1. The cutting position of the cutter 5 corresponds to the zero mark of the scale 19.

The position of the laser sensor 18 can be quickly and accurately determined according to the scale 19, and then the cutting position of the stainless steel strip can be adjusted.

[0039] Please see Figure 1 , Figure 2 and Figure 3 A servo motor 23 is provided on one side of the base 1. The output end of the servo motor 23 is fixedly connected to one end of the second shearing roller 22.

The first shearing roller 20 is rotated synchronously through the sprocket 24 and the chain, so as to realize the stable shearing of the stainless steel strip by the ring blade 21.

[0040] Please see Figure 4 and Figure 6 The top of the shearing table 2 is fixedly connected to two positioning plates 25 by bolts. The bottom of the positioning plates 25 and the top of the shearing table 2 are provided with semi-circular grooves 26.

[0041] Please see Figure 3Two limiting rings 27 are fixedly sleeved on the outer circumferential surface of the first shearing roller 20. The side of the limiting rings 27 closest to the shearing table 2 contacts the outer surface of the shearing table 2. The function of the limiting rings 27 is to axially limit the first shearing roller 20 to prevent it from axially moving during operation, and to ensure the precise fit between the annular blade 21 and the second shearing roller 22, thereby improving the stability and accuracy of shearing.

[0042] This embodiment of a precision stainless steel strip shearing device, by setting a first conveyor belt 6, a second conveyor belt 7, a hydraulic cylinder 4, a cutter 5, and a movable laser sensor 18, can assist in the conveying of the strip and detect the shearing length of the strip, automatically completing the fixed-length shearing operation of the strip, saving manpower and improving work efficiency. When the lead screw 9 rotates, it drives the limiting plate 11 to move under the action of the threaded tube 10, which can limit the two sides of the strip during the shearing process of strips of different sizes, preventing the strip from easily deviating and improving the shearing quality. By setting a second shearing roller 22, a detachable first shearing roller 20, and equidistantly arranged annular blades 21, it can complete the longitudinal shearing operation of the strip as needed, improving the practicality of the shearing device.

[0043] It should be noted that the outer surface of the base 1 is respectively equipped with motors for driving the first conveyor belt 6 and the second conveyor belt 7.

[0044] The working principle of the above embodiments is as follows:

[0045] The strip can be conveyed by external conveying equipment, and the first conveyor belt 6 and the second conveyor belt 7 can assist in conveying the strip. Based on the width of the stainless steel strip, the screw 9 is rotated by rotating the handwheel 12, causing the threaded tube 10 to synchronously adjust the spacing of the limiting plate 11. The limiting plate 11 limits the two sides of the conveyed strip to prevent it from deviating. During the transverse shearing operation, the first shearing roller 20 is removed. According to the required shearing length, the distance between the laser sensor 18 and the cutter 5 is adjusted with a scale 19 as a reference (adjusting the distance between the laser sensor 18 and the cutter 5 determines the shearing length of the strip). When the laser sensor 18 detects the strip passing through, the external conveying equipment... The first conveyor belt 6 and the second conveyor belt 7 stop operating. The hydraulic cylinder 4 drives the cutter 5 to move down to complete the shearing operation. The second conveyor belt 7 starts and moves the sheared strip forward. After the second conveyor belt 7 runs briefly, the external conveying equipment and the first conveyor belt 6 start operating to carry out the next fixed-length shearing operation of the strip. When it is necessary to perform longitudinal shearing on the strip, the first shearing roller 20 is installed on the shearing table 2 through the positioning plate 25. The servo motor 23 drives the second shearing roller 22 to rotate. Through the sprocket 24 and chain drive, the first shearing roller 20 rotates synchronously. The annular blade 21 on the first shearing roller 20 cooperates with the second shearing roller 22 to complete the longitudinal shearing of the strip during the movement.
