Abstract
Description
Technical Field
[0001] This application relates to the field of metal processing, and in particular to a stainless steel flying shear machine. Background Technology
[0002] Flying shears are a type of shearing machine primarily used for transverse shearing of moving rolled workpieces. They are widely used in the metal processing industry, especially in steel production, for shearing medium and small steel billets, thin slabs, small sections (bars), and hot-rolled and cold-rolled strip steel (including coated strips). However, the structure of commonly used flying shears is relatively complex, resulting in poor dynamic characteristics of their shearing mechanisms, which may affect the shearing effect and the overall performance of the equipment. For example, some crank-connecting rod type flying shears used in small steel mills may have limitations in the speed and thickness of metal workpieces they shear due to their complex structure. Utility Model Content
[0003] In order to improve the problem that the complex structure of conventional flying shears leads to poor power characteristics and limits the speed and thickness of cutting metal workpieces, this application provides a stainless steel flying shear.
[0004] The stainless steel flying shear machine provided in this application adopts the following technical solution:
[0005] A stainless steel flying shear machine includes a main base, a cutting mechanism for cutting metal workpieces is provided at the top center of the main base, a fixed frame for stable connection is provided around the outer surface of the main base on the cutting mechanism, a side support plate is provided on one side of the main base, a servo motor is provided at the top of the side support plate, a rotating rod is fixedly connected to the output end of the servo motor, a fixed ring for rotatable connection with the fixed frame is provided on both sides of the rotating rod, and an extrusion block for abutting and interacting with the cutting mechanism is fixedly provided in the middle of the rotating rod surface;
[0006] The main base is fixedly provided with a mold component for positioning and supporting the metal workpiece on one side of the fixed frame. The top of the mold component is provided with a punching cone for punching holes in the metal workpiece.
[0007] By adopting the above technical solution, the rotating rod rotates and drives the extrusion block to contact the cutting mechanism, thereby generating extrusion that causes the cutting component and the positioning component in the cutting mechanism to be horizontally interlaced, thus creating a cutting effect on the metal workpiece. At the same time, the fixed frame is fixedly arranged around the outer surface of the cutting mechanism. Only the rotating rod needs to rotate throughout the process. The structure is simple and easy to operate, thus avoiding power loss. Furthermore, the cutting action steps generated by the interlacing of the cutting component and the positioning component are simple, and the speed of completing the action cycle is fast, avoiding limitations on the speed and thickness of shearing the metal workpiece.
[0008] Preferably, the cutting mechanism includes a fixed base plate fixed in the middle of the upper end face of the main body base, a torsion spring fixed on the upper end face of the fixed base plate, a cutting element fixedly connected to the end of the torsion spring away from the fixed base plate, a friction element fixed on the top of the cutting element, the friction element movably abutting against the extrusion block, and a cutting opening for cutting metal workpieces through the side surface of the cutting element.
[0009] By adopting the above technical solution, the heated metal workpiece is transported to the cutting end and fits into the cutting end at an angle to form an auxiliary fixing effect. Then the cutting component is pressed down by pressure. At this time, the metal workpiece inside the cutting end and the outer part are pressed down to form a break. Then the torsion spring rebounds the cutting component and the metal workpiece back to their original position, which facilitates the subsequent transport of metal workpieces and the output of the cut metal workpiece.
[0010] Preferably, a positioning element is fixed on one side surface of the cutting element, and a positioning opening is formed through the side surface of the positioning element at the position of the cutting opening.
[0011] By adopting the above technical solution, the positioning component and the cutting component are aligned, thereby aligning the positioning port and the cutting port. After the cutting port cuts the metal workpiece, the thrust generated by the continuously conveyed subsequent metal workpieces will transport the cut metal workpiece into the positioning port, which facilitates the drilling operation of the metal workpiece and prevents the metal workpiece from shifting during movement.
[0012] Preferably, stabilizing plates are fixed on both sides of the outer surface of the cutting component, and a support column is fixed on one side of the front end of the two stabilizing plates.
[0013] By adopting the above technical solution, two stabilizing plates are fixed at both ends of the cutting component, which improves the longitudinal support force of the cutting component as a whole. When the cutting component is subjected to pressure and moves downward, it prevents the cutting component itself from deforming under pressure. At the same time, the support column provides auxiliary fixation for the cutting component and plays an auxiliary guiding role for the metal workpiece to be inserted into the cutting opening.
[0014] Preferably, the fixing frame includes side frames fixed on the top of the main body base and located on both sides of the cut-off piece. The surfaces of the two side frames are provided with rotating holes, and the two rotating holes are respectively rotatably connected to two fixing rings.
[0015] By adopting the above technical solution, the two side frames are located on both sides of the cutting part to form a clamping state to improve stability. At the same time, the rotating hole is rotatably connected to the fixed ring, thereby providing a fixed fulcrum for the rotation of the rotating rod.
[0016] Preferably, a front frame is fixed at the top of the main body base and at the front end of the cutting member, and friction rods are fixed at both ends of the front frame on the side near the cutting member. A rear frame is fixed at the top of the main body base and at the rear end of the cutting member, and a discharge groove is opened on the surface of the rear frame at the cutting opening.
[0017] By adopting the above technical solution, the friction rod is inserted into the top of the cutting part, thereby abutting against the fixed blocks on both sides of the extrusion block. When the rotating rod drives the extrusion block to rotate, the friction block rubs against the fixed block, thereby improving stability and reducing the shaking caused by the rotation of the extrusion block. The opening of the discharge chute facilitates the discharge of metal workpieces from the cutting opening.
[0018] Preferably, a fixed top plate is fixedly provided on the top of the front frame, the rear frame and the two side frames, and a movable groove is opened on the fixed top plate at the position of the extrusion block. A cover plate is screwed on the top of the fixed top plate at the movable groove.
[0019] By adopting the above technical solution, the opening of the movable groove provides space for the rotation of the extrusion block, preventing collision and misalignment. At the same time, a cover plate is installed at the position of the movable groove to form a top seal, preventing external debris from entering the movable groove and contacting the extrusion block, thereby causing damage.
[0020] Preferably, an electric actuator is fixedly mounted at the bottom of the fixed top plate at the position of the drilling cone, and the telescopic end of the electric actuator is fixedly connected to the top of the drilling cone.
[0021] By adopting the above technical solution, the telescopic end of the electric actuator pushes the punching cone downward, thereby punching holes in the metal workpiece at the top of the mold part and providing power for the movement of the punching cone.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. The rotating rod rotates within the rotating hole, causing the extrusion block to come into contact with the friction element and press downwards. The pressure on the friction element is transmitted to the cutting element, causing the cutting element and the positioning element to be staggered. During this staggering process, the metal workpiece in the cutting and positioning holes is staggered and extruded, thus creating a cutting effect. Then, as the rotating rod drives the extrusion block to rotate out, the pressure on the friction element is released, causing the torsion spring to rebound and the cutting element to return to its original position. The entire process only requires the rotation of the rotating rod, resulting in a simple structure and a smooth operation. This effectively prevents power loss during cutting and avoids limiting the speed and thickness of the metal workpiece being cut. Attached Figure Description

[0034] This application discloses a stainless steel flying shear machine.
[0035] The device's "up, down, left, right" perspectives are... Figure 2 The orientation of the attached diagram is the reference.
[0036] Reference Figure 1 , Figure 2 , Figure 3 A stainless steel flying shear machine includes a main base 1 with multiple anti-friction feet fixed at the bottom of the main base 1. The cutting mechanism 5 includes a fixed base plate 51 fixed at the middle of the upper surface of the main base 1. Torsion springs 52 are fixed on both sides of the upper surface of the fixed base plate 51. A cutting element 53 is fixed at the other end of the two torsion springs 52 relative to the fixed base plate 51. A cutting opening 54 is opened through the side surface of the cutting element 53. The overall shape of the cutting opening 54 changes according to the shape of the metal workpiece to be cut. At the same time, a positioning element 56 is fixed to one side surface of the cutting element 53 located at the cutting opening 54. A positioning opening 59 with the same shape as the center of the cutting opening 54 is opened on the side surface of the positioning element 53.
[0037] It should be noted that stabilizing plates 58 are fixedly provided on both sides of the outer surface of the cutting part 53 adjacent to the cutting opening 54, and supporting columns 57 are fixedly provided on both sides of the cutting part 53 at the front end of the stabilizing plates 58. A groove is opened inward in the middle of the upper end face of the cutting part 53, and a friction element 55 is inserted into the groove. The friction element 55 is made of silicone rubber, has a certain hardness, is easy to be locked in the groove, and can undergo a small deformation under pressure to achieve the function of sharing the pressure.
[0038] Reference Figure 2 , Figure 3 , Figure 5 The fixed frame 4 includes side frames 41 fixed on opposite sides of the surfaces of the two stabilizing plates 58. The tops of the two side frames 41 protrude from the cutting member 53, and a rotating hole 42 is provided through the surface of the protruding part of the side frame 41. At the same time, the bottoms of the two side frames 41 are fixed to the upper end face of the main body base 1. A front frame 45 is fixed on the front end surface of the cutting member 53. A through groove is provided on the surface of the front frame 45, and the width of the through groove is greater than the width of the cutting opening 54, so as to facilitate the insertion of metal workpieces.
[0039] Two friction rods 46 are fixedly mounted on the side of the front frame 45 facing the cutting part 53. The bottom surface of the friction rods 46 abuts against both sides of the upper end face of the cutting part 53. The bottom of the front frame 45 is fixedly connected to the upper end face of the main body base 1. The side of the positioning part 56 away from the cutting part 53 is fixedly connected to the rear frame 43. The surface of the rear frame 43 is provided with a discharge groove 44 at the position of the positioning port 59. The width of the discharge groove 44 is greater than that of the positioning port 59 to facilitate the discharge of the metal workpiece. The bottom of the rear frame 43 is fixedly connected to the upper end face of the main body base 1, thus forming a fixed frame 4 that is completely surrounded and covered on the outer surface of the cutting mechanism 5.
[0040] It should be noted that the top of the two side frames 41, the rear frame 43, and the front frame 45 are all fixed with screws to a fixed top plate 6. The surface of the fixed top plate 6 is provided with a movable groove 14 at the position of the cutting part 53, and the width of the movable groove 14 is 3-4 cm larger than the width of the friction part 55. A cover plate 7 is placed on the top of the movable groove 14. The cover plate 7 is connected to the fixed top plate 6 by screws and can be detached. At the same time, a transmission device is provided at the position of the through groove of the front frame 45. The transmission device is connected to the heating device, thereby transporting the heated metal workpiece to the cutting part 53. The heated metal workpiece is slightly softened, which facilitates subsequent cutting and drilling operations.
[0041] Reference Figure 2 , Figure 4A side support plate 2 is fixedly provided on the upper surface of the main base 1 on one side of the side frame 41. A flat surface is provided on the side support plate 2 away from the main base 1, and a servo motor 3 is fixed to the flat surface with screws. The output shaft of the servo motor 3 is directly above the part of the cutting piece 53, and a rotating rod 8 is fixedly connected to the end of the output shaft of the servo motor 3 through a coupling. The rotating rod 8 is inserted through two rotating holes 42, and a fixing ring 9 is fixedly provided on the surface of the rotating rod 8 at the position of the two rotating holes 42. The two fixing rings 9 are respectively fixed longitudinally in the two rotating holes 42 and can rotate laterally. At the same time, a pressing block 10 is fixedly provided on the surface of the rotating rod 8 at the position of the friction piece 55. The pressing block 10 is elliptical in shape, and when the pressing block 10 is completely vertical, it applies downward pressure to the friction piece 55, causing the cutting piece 53 to move downward.
[0042] It should be noted that an electric push rod 11 is fixedly installed on the lower end face of the fixed top plate 6 on one side of the rear frame 43. The telescopic end of the electric push rod 11 extends vertically downward, and a punching cone 12 is fixedly connected to the end of the telescopic end. The bottom of the punching cone 12 is conical. A mold part 13 is fixedly installed on the upper end face of the main body base 1 at the position of the punching cone 12. The mold part 13 is aligned with the center of the punching cone 12.
[0043] The implementation principle of a stainless steel flying shear machine according to an embodiment of this application is as follows: When using this device, the heated metal workpiece is transported from the through groove at the bottom of the front frame 45 to the cutting port 54 by an external transmission mechanism. As the metal workpiece is continuously input, when the front end of the metal workpiece is inserted into the positioning port 59, the servo motor 3 runs. The output shaft of the servo motor 3 drives the rotating rod 8 to rotate. As the rotating rod 8 rotates, the protruding end of the extrusion block 10 is gradually pressed into the friction member 55, thereby applying pressure to the friction member 55. The friction member 55 is pressed downward by the pressure, thereby causing the cutting member 53 to move downward as a whole and compressing the torsion spring 52. The rapid downward pressing of the cutting member 53 forms an interlock with the positioning member 56. As the cutting member 53 and the positioning member 56 interlock, the cutting port 54 and the positioning port 59 respectively form a clamping and fixing effect on the metal workpiece, generating an interaction force to cut the metal workpiece.
[0044] After the metal workpiece is cut, the rotating rod 8 continues to rotate, causing the protruding end of the extrusion block 10 to rotate out of the surface of the friction member 55, thereby canceling the pressure applied to the cutting member 53. Subsequently, the torsion spring 52 loses pressure and rebounds, driving the cutting member 53 back to its original position, so that the cutting opening 54 and the positioning opening 59 are aligned. As subsequent metal workpieces are continuously input, the cut metal workpieces in the positioning opening 59 are pushed out to the discharge groove 44. As the cut metal workpieces are pushed out, they fall onto the surface of the mold member 13. The electric push rod 11 is operated by the operator to perform one extension and retraction cycle, thereby driving the punching cone 12 to impact the surface of the metal workpiece. At this time, the metal workpiece is still in a high-temperature softened state, thus completing the punching work of the metal workpiece. After the punching is completed, the metal workpiece is pushed out by the subsequent cut metal workpieces and falls into the external storage device for collection.
[0045] The above are merely optional embodiments of this disclosure and are not intended to limit this disclosure. Various modifications and variations can be made to this disclosure by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the scope of protection of this disclosure.
