Description

Technical Field

[0001] This utility model relates to the field of machining equipment, and more specifically, to a guided flying shear guide mechanism and a flying shear device. Background Technology

[0002] Flying shear guide channels are primarily used to constrain the movement trajectory of the material being sheared (such as strip and wire), ensuring that the material maintains the correct position and orientation when entering the flying shear shear zone, reducing material swaying and vibration. The guide channel acts like a "track," providing a stable movement path for the rolled piece, while the flying shear performs the shearing action dynamically. The key to their synergy lies in the fact that the positioning accuracy of the guide channel determines the accuracy of the shearing position, and the speed matching of the flying shear and the dynamic constraint of the guide channel together guarantee the shearing quality. However, in conventional flying shear guide channel designs, during material movement, due to the fixed guidance of the guide channel, the inner wall of the guide channel will collide and rub against the material, and the movement trajectory of the steel cannot be controlled, ultimately leading to dimensional deviations and shearing failures in the finished product.

[0003] Due to the actual conditions on the production site, if the guide chute guides the material in only one direction, it will increase downtime for debugging, reduce production efficiency, and prevent the material from entering the shearing zone in a suitable posture, thus compromising shearing accuracy. Steel piling accidents frequently occur at the guide chute opening, causing the integrally welded guide chute to twist and deform, the weld to crack, and ultimately, failure. Utility Model Content

[0004] The purpose of this utility model includes, for example, providing a guided flying shear guiding mechanism and flying shear device, which can guide materials in multiple directions to meet the needs of various actual working conditions. It can also prevent the guide channel from twisting and deforming and the weld from cracking due to steel temperature changes, flying shear malfunctions, etc., which could ultimately lead to steel pile-up accidents.

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0036] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0039] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.

[0040] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0041] In existing technologies, when materials are guided to the flying shear station via guide grooves, the guide grooves generally have only one guiding direction, which can only guide materials along the same direction. They cannot guide materials to different stations according to different processing methods, resulting in a single processing method and limited use. In addition, the width of the guide grooves is uniform, and the materials are prone to shaking when moving, which causes them to collide and come into contact with the groove walls, leading to increased abnormal noise and easy damage to the guide grooves and materials.

[0042] In view of this, the designers have provided a guided flying shear guide mechanism that can adjust the opening and orientation of the channel as needed, thereby adapting to the usage requirements of different scenarios, making it flexible and widely applicable.

[0043] Please refer to Figures 1-8 This embodiment provides a guided flying shear guide mechanism, including:

[0044] The directional guide unit 100 and the adjustable-opening guide unit 200 are provided; the directional guide unit 100 is provided with a guide channel 150; the adjustable-opening guide unit 200 includes a drive mechanism 210 and two guide plates 220. The drive mechanism 210 is installed on the directional guide unit 100, and the two guide plates 220 are rotatably installed on the directional guide unit 100. A guide channel connecting the guide channel 150 is formed between the two guide plates 220.

[0045] The drive mechanism 210 is simultaneously connected to the two guide plates 220 for transmission. The drive mechanism 210 is used to drive the two guide plates 220 to rotate in order to adjust the opening of the guide channel.

[0046] As described above, the guided flying shear mechanism provided in this embodiment works as follows:

[0047] During equipment operation, the opening and orientation of the guide channel can be adjusted in advance as needed. When the material moves from the guide channel 150 of the directional guiding unit 100 to the guide channel, the opening of the guide channel is adapted to the size of the material. Under the guidance of the guide channel, the material is less likely to collide with the side wall, reducing collision damage. At the same time, the material can also move in the set direction to the next workstation under the guidance of the guide channel, which is beneficial for subsequent processing. Because the orientation of the guide channel can be adjusted in advance, the direction of material movement can be adjusted according to different materials or different subsequent processing steps, so that the material can be guided to different workstations, making it flexible and widely applicable.

[0048] The following embodiments illustrate the details of the guided flying shear mechanism of this application.

[0049] Please refer to Figures 1-8 In this embodiment, optionally, the guided flying shear guiding mechanism includes a directional guiding unit 100 and an adjustable-aperture guiding unit 200. The directional guiding unit 100 is connected to the adjustable-aperture guiding unit 200, and the material can move from the directional guiding unit 100 to the adjustable-aperture guiding unit 200, and then be guided to the set station through the adjustable-aperture guiding unit 200.

[0050] It should be understood that the material guided by the flying shear guide mechanism can be strip or wire, etc.

[0051] In this embodiment, optionally, the directional guiding unit 100 includes two supports 110, two directional baffles 120, a guide cylinder 130, and a heat insulation plate 140. The guide cylinder 130 can be a cuboid cylinder, and includes a bottom plate 131, a top plate 132, and two side plates 133. The two supports 110 are fixed to the bottom of the bottom plate 131 and are spaced apart in a predetermined direction to support the bottom plate 131. The two side plates 133 are fixed to the bottom plate 131 and are spaced apart in the width direction of the bottom plate 131. The top plate 132 is mounted above the two side plates 133 and is detachably connected to them. Thus, the bottom plate 131, top plate 132, and two side plates 133 cooperate to form the cavity of the guide cylinder 130, which is also the guide channel 150, and the guide channel 150 is approximately a cuboid hole. During operation, material can enter the guide channel 150 between the two directional baffles 120 and move from the rear side of the side plate 133 to the front side of the side plate 133. The two directional baffles 120 are respectively fixed to the rear side of the two side plates 133, and the two directional baffles 120 are arranged in a trumpet shape. That is, the distance between the two directional baffles 120 gradually increases from the side where the directional baffle 120 is connected to the side plate 133 to the other side, thereby facilitating the introduction of material. The heat insulation plate 140 is installed on the front side of the top plate 132, and the heat insulation plate 140 and the portion of the bottom plate 131 extending out of the side plate 133 are arranged at intervals.

[0052] Optionally, each side plate 133 is provided with two snap-fit ​​protrusions 134, and the top plate 132 is provided with snap-fit ​​posts 135 and handles 136. The snap-fit ​​posts 135 can engage with the snap-fit ​​protrusions 134 to prevent the top plate 132 from moving upward away from the side plate 133. The top plate 132 can also move horizontally, thereby disengaging the snap-fit ​​posts 135 from the snap-fit ​​protrusions 134, making it easy to remove the top plate 132. Removing the top plate 132 facilitates maintenance of the guide channel 150 and allows for clearing of the guide channel 150 in case of material blockage.

[0053] Optionally, the front side of the base plate 131 extends beyond the front side of the side plate 133. Two rotating through holes 137 are provided on the portion of the base plate 131 extending beyond the front side of the side plate 133. The two rotating through holes 137 are spaced apart along the width direction of the guide channel 150. The preset direction can be understood as the length direction of the guide channel 150, and the width direction is perpendicular to the preset direction. Each rotating through hole 137 can be a circular hole, into which a bearing can be installed.

[0054] Optionally, the heat insulation plate 140 is provided with a first snap-fit ​​part 141, which can be configured as a spline hole.

[0055] In this embodiment, optionally, the adjustable guide unit 200 includes a drive mechanism 210, two guide plates 220, two guide rollers 230, two first rotating shafts 240, and two second rotating shafts 250. The drive mechanism 210 is mounted on the heat insulation plate 140. The two guide plates 220 are rotatably mounted in two rotating through holes 137 on the base plate 131 via the two first rotating shafts 240. One end of each of the two second rotating shafts 250 is inserted into a positioning hole 221 on one of the two guide plates 220. The two guide rollers 230 are respectively sleeved on the outside of the two second rotating shafts 250 and rotatably connected to the two guide plates 220. The first rotating shafts 240 and the second rotating shafts 250 are arranged in parallel and spaced apart. The axis of the first rotating shaft 240 or the second rotating shaft 250 is parallel to a preset axis, the extension direction of which can be understood as the height direction of the guide channel 150. The two guide plates 220 are arranged at intervals along the width direction of the guide channel 150. A guide channel communicating with the guide channel 150 is formed between the two guide plates 220. The heat insulation plate 140 and the bottom plate 131 respectively close the top and bottom of the guide channel. When the two guide plates 220 rotate, the distance between them can be adjusted, thereby adjusting the opening of the guide channel. Furthermore, when the rotation angles of the two guide plates 220 are not consistent, the guiding direction of the guide channel can be adjusted.

[0056] Optionally, the drive mechanism 210 is connected to the two guide plates 220, and can drive the two guide plates 220 to rotate relative to the base plate 131 around their respective first pivot axes 240. For example, the drive mechanism 210 can drive the two guide plates 220 to rotate together simultaneously, or the drive mechanism 210 can independently control the rotation of the two guide plates 220, which can be designed as needed. In this embodiment, in order to improve operating efficiency, the drive mechanism 210 drives the two guide plates 220 to rotate together simultaneously.

[0057] For example, the drive mechanism 210 includes an actuation component and a linkage component. The actuation component is mounted on the heat insulation plate 140, and the linkage component is connected to both the actuation component and the two guide plates 220. The actuation component is used to drive the two guide plates 220 to move simultaneously through the linkage component in order to adjust the opening and orientation of the guide channel.

[0058] Optionally, each guide plate 220 is provided with a positioning hole 221.

[0059] Optionally, the actuating components include a positioning seat 211, a force transmission rod 212, and two locking members 213. The bottom of the positioning seat 211 has a second engaging portion 214, which can be configured as an external spline and can be detachably engaged with a first engaging portion 141. The positioning seat 211 has a sliding hole inside, through which the force transmission rod 212 slidably passes. At least a portion of the force transmission rod 212 can be machined with external threads. Both locking members 213 can be nuts, and both can be screwed onto the outside of the force transmission rod 212, located on opposite sides of the positioning seat 211. The locking members 213 can simultaneously engage with both the force transmission rod 212 and the positioning seat 211, thereby restricting the sliding of the force transmission rod 212 relative to the positioning seat 211. Alternatively, the locking element 213 can disengage the restraints on the force transmission rod 212 and the positioning seat 211, thereby allowing the force transmission rod 212 to slide relative to the positioning seat 211. In specific operation, if it is necessary to adjust the position of the force transmission rod 212, rotate the two locking elements 213 to separate them from the positioning seat 211. At this time, the force transmission rod 212 can be slid. After sliding, rotate the two locking elements 213 again to clamp the positioning seat 211. The operation is convenient.

[0060] It should be understood that machining external threads on some sections of the force transmission rod 212 reduces machining difficulty, material consumption, and costs.

[0061] Optionally, the linkage assembly includes a connecting seat 215, two swing arms 216, and a fixing pin 217. The connecting seat 215 is fixedly connected to the force transmission rod 212 via the fixing pin 217. One end of each of the two swing arms 216 is rotatably connected to the connecting seat 215. The other end of each of the two swing arms 216 is provided with a mounting hole 218, and each of the two swing arms 216 is rotatably connected to two second rotating shafts 250 through the corresponding mounting holes 218. With this design, when the force transmission rod 212 slides in a preset direction, the force transmission rod 212 can drive the connecting seat 215 to slide, which in turn drives the two swing arms 216 to rotate, thereby driving the two guide plates 220 to rotate. Correspondingly, the two guide rollers 230 located on the guide plates 220 also move together with the guide plates 220.

[0062] It should be understood that when the force transmission rod 212 is located in the middle position of the two guide plates 220, that is, the angle between the two guide plates 220 and the force transmission rod 212 is the same, and the force transmission rod 212 is located on the angle bisector of the angle formed by the two guide plates 220, the force transmission rod 212 slides. During the adjustment of the opening between the two guide plates 220, the angle between the two guide plates 220 and the force transmission rod 212 always remains the same, and the guide channel can always guide the material along the preset direction. When it is necessary to adjust the guide direction, loosen the fixing pin 217, push the connecting seat 215 forward, and separate the force transmission rod 212 from the connecting seat 215. Then, unscrew the locking piece 213 on the side of the force transmission rod 212 away from the connecting seat 215, and then the force transmission rod 212 can be dragged to remove it from the positioning seat 211. Lift the positioning seat 211 upwards to separate the first locking part 141 and the second locking part 214. Then rotate the positioning seat 211 and insert it back into the first locking part 141. Finally, fix the force transmission rod 212, the positioning seat 211, and the connecting seat 215 together. At this time, by adjusting the angle of the positioning seat 211, the extension direction of the force transmission rod 212 can be adjusted, so that the angles between the two guide plates 220 and the force transmission rod 212 are unequal, thereby adjusting the guiding direction of the guide channel, which has a wide range of applications.

[0063] The guided flying shear mechanism provided in this embodiment can adjust the opening and direction of the guide channel as needed, making it flexible and versatile, meeting the needs of various scenarios, and offering low operating costs for efficient material handling. During normal operation, material enters the guide channel 150 between the two directional baffles 120, then enters the guide channel with a pre-set opening and angle, and is guided to the designated workstation. Because two guide rollers 230 are located at the front end of the guide channel, the guide rollers 230 rotate when the material contacts them, reducing friction and collision, and ensuring smoother guidance.

[0064] This embodiment also provides a flying shear device, including the above-mentioned guided flying shear guide mechanism, which has at least the advantages of wide applicability.

[0065] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
