[0002] The double-wing swing shear machine is a metal sheet shearing device, mainly used for cold shearing processing of metal sheets; the double-wing swing shear machine adopts a double-wing shearing mechanism, and the shearing blades are symmetrically distributed. During shearing, the upper and lower blades move relative to each other to achieve the shearing of metal sheets. This structure makes the shearing force evenly distributed and the shearing quality good.

[0003] The double-wing swing shear machine adopts precision guide rails and ball screw pairs to ensure the accuracy during the shearing process. The shearing blades are made of materials with high hardness and high wear resistance, which ensures the sharpness of the shearing edge and the shearing quality. At the same time, it is driven by a high-speed motor, and the shearing speed is relatively fast, greatly improving the production efficiency. With an automatic feeding system, continuous shearing is realized, further improving the production efficiency. Therefore, the double-wing swing shear machine is easy to operate and easy to get started.

[0004] However, most of the existing double-wing swing shear machines on the market are prone to looseness of the columns after long-term use, resulting in shaking of the shear bed base during work, thereby reducing the overall stability of the device, and further affecting the processing quality of subsequent materials, and cannot meet the needs of users.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Referring to Figure 1 and Figure 2 , an embodiment provided by the present utility model: A double - flying - wing type swing shearing machine includes a support seat 6. In the middle of the top of the support seat 6, a first gland 1 is provided. The top of the first gland 1 is rotatably connected to a column 2. A second gland 3 is arranged outside the column 2. A plug 4 is arranged at the top of the column 2. A round nut 5 is threadedly connected to the outside of the column 2. In the middle of the outside of the column 2, a shearing machine base 7 is fixedly connected. On the left and right sides of the top of the support seat 6, first key bars 8 are fixedly connected. The top of the first key bar 8 is fixedly connected to a frame 9. Arc racks 10 are fixedly connected to the far - away sides of the two frames 9. First fixing plates 17 are fixedly connected to the left and right sides of the support seat 6. A second key bar 16 is fixedly connected to one side of the first fixing plate 17. A plurality of movable bearings 25 are arranged inside the second gland 3. The second gland 3 is rotatably connected to the column 2 through the movable bearings 25. A swing arm 15 is fixedly connected to one side of the second key bar 16. A backing plate 13 is fixedly connected to the top of the frame 9. A liner 14 is connected to the top of the backing plate 13. A second adjusting plate 22 is fixedly connected to one side of the swing arm 15. A first adjusting plate 21 is arranged at the bottom of the second adjusting plate 22. A third gland 11 is fixedly connected to the bottom of the first adjusting plate 21. A gear 12 is rotatably connected to the top of the third gland 11. The two gears 12 are respectively meshed with the corresponding arc racks 10;

[0029] Specifically, the device can drive the swing arm 15 to rotate through an external switch. When the swing arm 15 rotates, the gear 12 on it will closely cooperate with the arc rack 10 and rotate along the trajectory of the arc rack 10. This design makes the shearing process more precise and achieves the required cutting shape and size. Whether it is simple straight-line shearing or complex curve shearing, the device can easily handle it, greatly improving production efficiency. In addition, the device also firmly fixes the second gland 3 on the outside of the column 2 through the ingenious cooperation between the movable bearing 25 and the round nut 5. This design not only strengthens the stability of the column 2 but also makes the whole device more durable. The fixed seat 24 can effectively share the bearing force of the transition frame 19 on the shearing machine base 7 on the shearing machine base 7, making the shearing machine base 7 placed more stably. This design not only improves the overall stability of the device but also reduces the risk of the shearing machine base 7 shaking during long-term use.

[0030] Refer to Figure 2 , a plurality of fixed seats 24 are fixedly connected to the top of the support seat 6, and a buffer pad 23 is fixedly connected to one side of the fixed seat 24;

[0031] Specifically, the stability of the placement of the fixed seat 24 is increased through the buffer pad 23.

[0032] Refer to Figure 2 , a transition frame 19 is arranged on the upper side of the column 2, a plurality of bull's-eye bearings 20 are rotatably connected to the top of the transition frame 19 at equal intervals, and a second fixing plate 18 is fixedly connected to the bottom of the transition frame 19;

[0033] Specifically, the swing arm 15 can be placed through the transition frame 19, making the placement of the swing arm 15 more stable.

[0034] Refer to Figure 1 , the shearing machine base 7 is electrically connected to an external switch;

[0035] Specifically, the operation of the shearing machine base 7 can be controlled through an external switch.

[0036] Working principle: When using the device, the swing arm 15 can be driven to rotate through an external switch. At this time, the gear 12 on the swing arm 15 will rotate along the trajectory of the arc rack 10, and shearing work can be carried out to achieve the required cutting shape and size. The second gland 3 can be fixed on the outside of the column 2 through the cooperation between the movable bearing 25 and the round nut 5, which can further strengthen the stability of the column 2. Then, the fixed seat 24 can share the bearing force of the transition frame 19 on the shearing machine base 7 on the shearing machine base 7, so that the shearing machine base 7 can be placed more stably, and the situation of the shearing machine base 7 shaking during long-term use can be avoided. Thus, the overall stability of the device can be improved, and the subsequent processing quality of the material will not be affected, meeting the needs of users.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
