Description

Technical Field

[0001] This utility model relates to the field of material guiding technology, specifically a material guiding adjustment mechanism for a bending machine. Background Technology

[0002] The material guiding mechanism is used to support and guide the bending material, making it easier for the material to enter the bending die. Some devices have also appeared in the prior art, such as the announcement number: CN222359072U, which describes: "A pipe bending machine that facilitates feeding, wherein when the rotating plate rotates, it will abut against the linkage rod through the arc groove, forcing the linkage rod to slide along the arc groove, but the connecting rod passes through the straight groove and is slidably connected";

[0003] Although the above device can ensure that the material is fixed by two sets of feeding boxes, and then keep the axis of the fed tube perpendicular to the bending rod to prevent the axis of the tube from shifting and causing the bending angle to shift, for square or round tubes, the contact surface between the material box and the tube is curved. The curved surface makes it easy to slip when clamping the square tube, reducing the stability during clamping. Utility Model Content

[0004] The purpose of this utility model is to provide a material guide adjustment mechanism for a bending machine to solve the problems mentioned above in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A material feeding and guiding adjustment mechanism for a bending machine includes a first mounting base installed on the upper surface of the bending machine body, a first extrusion frame fixedly connected to the front surface of the first mounting base, and a first extrusion bracket slidably connected inside the first extrusion frame.

[0007] The upper surface of the bending machine body is provided with a material support mechanism, which includes a material support frame and a limiting rail. The material support frame is fixedly connected to the upper surface of the bending machine body, and the limiting rail is fixedly connected to the inner surface of the material support frame. A rotating roller is rotatably connected inside the limiting rail. The upper surface of the bending machine body is provided with a clamping mechanism, which includes a base and a second mounting base. The base is fixedly connected to the upper surface of the bending machine body, and a first hydraulic cylinder is fixedly connected to the upper surface of the base. The second mounting base is fixedly connected to the upper surface of the bending machine body, and a guide rail is slidably embedded in the rear surface of the second mounting base. The output end of the first hydraulic cylinder is fixedly connected to the guide rail.

[0008] Furthermore, the front surface of the guide rail is fixedly connected to an insertion post, the insertion post penetrates the second mounting base, and the insertion post and the second mounting base are slidably connected.

[0009] Furthermore, a second extrusion seat is slidably connected to the outer surface of the guide rail, and a third hydraulic cylinder is fixedly connected to the side surface of the guide rail, with the output end of the third hydraulic cylinder fixedly connected to the second extrusion seat.

[0010] Furthermore, the inner surface of the second extrusion seat is fixedly connected to a second limiting rod, the outer surface of the second limiting rod is nested and slidably connected to a second extrusion frame, the interior of the second extrusion seat is rotatably connected to a second stud, and the second stud and the second extrusion frame are threadedly connected.

[0011] Furthermore, a first limiting rod is fixedly connected to the inner surface of the first mounting base, and the first extrusion frame and the first limiting rod are slidably connected.

[0012] Furthermore, the inner surface of the first extrusion frame is rotatably connected to a first stud, and the first extrusion frame and the first stud are threadedly connected.

[0013] Furthermore, the front surface of the first extrusion frame is provided with a V-shaped groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The second limiting rod limits the sliding of the second extrusion frame. Rotating the second stud can push the second extrusion frame outward under the push of the thread. The second extrusion frame matches the first extrusion frame. In addition, under the push of the first hydraulic cylinder, the second extrusion seat can also directly cooperate with the first mounting seat to extrude materials. It is suitable for conveying materials with a flat contact surface.

[0016] 2. The first limiting rod guides the movement of the first extrusion frame. By rotating the first stud, the first extrusion frame moves outward under the push of the thread, so that the V-shaped groove contacts the material. The V-shaped groove cooperates with the second extrusion frame to clamp the round material, thereby improving the applicability of the device. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not 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 effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the present invention, a bending machine material guide adjustment mechanism includes a first mounting seat 3 installed on the upper surface of the bending machine body 1, a first extrusion frame 301 fixedly connected to the front surface of the first mounting seat 3, and a first extrusion frame 303 slidably connected inside the first extrusion frame 301.

[0024] A material support mechanism 2 is provided on the upper surface of the bending machine body 1. The material support mechanism 2 includes a material support frame 201 and a limiting rail 202. The material support frame 201 is fixedly connected to the upper surface of the bending machine body 1, and the limiting rail 202 is fixedly connected to the inner surface of the material support frame 201. A rotating roller 203 is rotatably connected inside the limiting rail 202. A clamping mechanism 4 is provided on the upper surface of the bending machine body 1. The clamping mechanism 4 includes a base 401 and a second mounting base 403. The base 401 is fixedly connected to the upper surface of the bending machine body 1, and a first hydraulic cylinder 402 is fixedly connected to the upper surface of the base 401. The second mounting base 403 is fixedly connected to the upper surface of the bending machine body 1, and a guide rail 404 is slidably connected to the rear surface of the second mounting base 403. The output end of the first hydraulic cylinder 402 is fixedly connected to the guide rail 404.

[0025] Specifically, during use, the material to be bent is placed on the upper surface of the material support mechanism 2. The rotating roller 203 can rotate, reducing the friction between the material and the bending machine body 1 during material conveying. The rotating roller 203 is connected to the material support mechanism 2 through the limiting rail 202. Therefore, by sliding the rotating roller 203 along the opening direction of the limiting rail 202, the worn rotating roller 203 can be replaced. The first extrusion frame 303 can extend from inside the first extrusion frame 301 to clamp the material. The output end of the first hydraulic cylinder 402 pushes the guide rail 404 to move, so that the guide rail 404 and the second mounting seat 403 are separated, which facilitates the driving of the second extrusion seat 5, so that the second extrusion seat 5 cooperates with the first extrusion frame 301 or the first extrusion frame 303 to clamp the material.

[0026] Example 1

[0027] like Figure 1-4 As shown, an insertion post 405 is fixedly connected to the front surface of the guide rail 404. The insertion post 405 passes through the second mounting base 403 and is slidably connected to the second mounting base 403. A second extrusion seat 5 is slidably connected to the outer surface of the guide rail 404. A third hydraulic cylinder 501 is fixedly connected to the side surface of the guide rail 404. The output end of the third hydraulic cylinder 501 is fixedly connected to the second extrusion seat 5.

[0028] In this embodiment, the insertion post 405 guides the movement between the second mounting base 403 and the guide rail 404, and activates the third hydraulic cylinder 501. The output end of the third hydraulic cylinder 501 pushes the second extrusion seat 5 to slide along the guide rail 404. When the material is bent, it can drive the material to move towards the mold, providing displacement compensation.

[0029] like Figure 1-4 As shown, a second limiting rod 502 is fixedly connected to the inner surface of the second extrusion seat 5, and a second extrusion frame 503 is nested and slidably connected to the outer surface of the second limiting rod 502. A second stud 504 is rotatably connected inside the second extrusion seat 5, and the second stud 504 and the second extrusion frame 503 are threadedly connected.

[0030] In this embodiment, the second limiting rod 502 limits the sliding of the second extrusion frame 503. Rotating the second stud 504 can cause the second extrusion frame 503 to move outward under the push of the thread. The second extrusion frame 503 matches the first extrusion frame 303. In addition, under the push of the first hydraulic cylinder 402, the second extrusion seat 5 can also directly extrude the material, which is suitable for conveying materials with a flat contact surface.

[0031] Example 2

[0032] Based on Embodiment 1, in order to overcome the problem that it is inconvenient to clamp and guide the circular pipe in Embodiment 1.

[0033] like Figure 1-4 As shown, a first limiting rod 302 is fixedly connected to the inner surface of the first mounting base 3, the first extrusion frame 303 is slidably connected to the first limiting rod 302, the inner surface of the first extrusion frame 301 is rotatably connected to the first stud 304, the first extrusion frame 303 and the first stud 304 are threadedly connected, and a V-shaped groove 305 is opened on the front surface of the first extrusion frame 303.

[0034] In this embodiment, the first limiting rod 302 guides the movement of the first extrusion frame 303. By rotating the first stud 304 and being pushed by the thread, the first extrusion frame 303 moves outward so that the V-shaped groove 305 contacts the material. The V-shaped groove 305 cooperates with the second extrusion frame 503 to clamp the circular material, thereby improving the applicability of the device.
