Description
Technical Field
[0001] This utility model belongs to the technical field of aluminum rod hot shearing devices, and in particular relates to a hot shearing device for aluminum rods. Background Technology
[0002] With the rapid development of industries such as aerospace, automobile manufacturing, and building materials, the market demand for aluminum rods, as a lightweight, high-strength, and easy-to-process metal material, continues to rise. In the aluminum rod processing and production process, the hot shearing device is the key equipment for achieving fixed-length cutting of aluminum rods. Its shearing accuracy and efficiency directly determine the quality and production progress of subsequent aluminum product processing. Therefore, a high-performance aluminum rod hot shearing device is needed to accurately cut aluminum rods at high temperatures.
[0003] However, existing hot shearing devices are not convenient for fixing aluminum bars during use, causing the aluminum bars to shift and shake during hot shearing operations. This not only reduces the flatness of the sheared section of the aluminum bars, but also affects the quality and efficiency of subsequent processing steps. Utility Model Content
[0004] The purpose of this utility model is to provide a hot shearing device for aluminum bars. By setting a fixing part, it solves the problem that existing hot shearing devices are not convenient for fixing aluminum bars during use, which causes the aluminum bars to shift and shake during hot shearing operations. This not only reduces the flatness of the sheared section of the aluminum bars, but also affects the quality and efficiency of subsequent processing steps.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a hot shearing device for aluminum bars, comprising two support legs and a support plate fixedly connected between the two support legs, and further comprising: a fixing part installed on the top of the two support legs; a cutting part installed between the two support legs; the fixing part includes a driving assembly installed on the top of the two support legs; and a fixing component installed on the driving assembly; the driving assembly includes an I-shaped support plate fixedly connected to the top of the two support legs, an electric telescopic rod fixedly connected to the top of the I-shaped support plate, a connecting block fixedly connected to the output shaft of the electric telescopic rod, and two connecting rods hinged on the connecting block; the two connecting rods are located on the front and rear sides of the connecting block respectively, and are mirror images of each other, ensuring that the fixing rods can move closer or further away synchronously, thereby achieving uniform clamping of the aluminum bar.
[0006] Furthermore, the cutting section includes a cutting assembly mounted between two support legs; a power assembly mounted on the cutting assembly; and the cutting assembly located on the right side of the pallet.
[0007] Furthermore, the fixing component includes two limiting slide grooves formed on the top of the I-shaped support plate, each containing a slider, and each slider has a fixed rod fixedly connected to its bottom. Connectors are provided on the two fixed rods. The two limiting slide grooves are located on the front and rear sides of the electric telescopic rod, respectively, and the two sliders are located on opposite sides of the two limiting slide grooves. The connection includes hinge blocks fixedly connected to the tops of the two sliders, and each hinge block is hinged to one of the two connecting rods. The two hinge blocks are mirror images of each other and are the direct components for realizing the "power-clamping action" conversion.
[0008] Furthermore, the cutting assembly includes a support frame fixedly connected between two support legs. Two support plates are disposed within the support frame. A cutting blade is fixedly connected to the side of each support plate that is close to it, and two guide rods are fixedly connected to the side of each cutting blade that is far from it. Several guide rods extend beyond the support frame on their far-away sides and are slidably connected to the support frame. The support frame is located on the right side of the support plate, and the guide rods restrict the movement direction of the support plates, ensuring that the two cutting blades are always parallel and aligned.
[0009] Furthermore, the power assembly includes a hydraulic cylinder fixedly connected to the support frame. The output shaft of the hydraulic cylinder is fixedly connected to the support plate located below. Two trapezoidal grooves are formed on the front inner wall of the support frame. Two racks are arranged inside the support frame. The front sides of the two racks extend into the two trapezoidal grooves respectively. The two racks are slidably connected to the two trapezoidal grooves respectively. The sides of the two racks that are far apart from each other are fixedly connected to the two support plates respectively. A transmission component is arranged between the two racks. The two trapezoidal grooves are mirror images of each other. The transmission component includes a rotating rod rotatably connected to the front inner wall of the support frame. A gear is fixedly connected to the outer wall of the rotating rod. The gear is hinged to the two racks. The gear is located between the two racks and is the key transmission structure for realizing "single power - double blade synchronous shearing".
[0010] This utility model has the following beneficial effects: 1. By setting a fixing part and driving it through an electric telescopic rod, the slider moves along the limiting groove through the linkage of the connecting block, connecting rod and hinge block, so that the fixing rods move closer to each other and cooperate with the support plate to fix the aluminum rod. The fixing can be released by reversing the rotation, which avoids positional displacement and shaking during hot shearing, effectively ensures the flatness of the shearing section, improves the quality of subsequent processing and ensures operation safety. 2. By setting up a cutting section, the hydraulic cylinder is activated to push the lower support plate to move. This support plate drives the corresponding rack to slide in the trapezoidal groove. The sliding rack drives the gear to rotate via the rotating rod. The gear then drives another rack to move, thereby driving the upper support plate to move downward. This causes the two support plates to bring their corresponding guide rods closer together. The parallel design of the guide rods ensures that the two support plates drive the cutting blade to move smoothly to complete the aluminum rod cutting. Reverse rotation will move the two cutting blades away from each other, reducing the labor intensity and operation difficulty of the operator, improving the overall efficiency of the hot shearing operation, and reducing material waste caused by cutting deviation.
[0011] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] A specific application of this embodiment is as follows: In use, the device is placed at the discharge port of the heating furnace via the support leg 111, with the cutting part 3 corresponding to the discharge port. When the aluminum rod comes out of the discharge port of the heating furnace, it enters the support leg 111 through the cutting part 3 and sits on the support plate 112. Then, the electric telescopic rod 212 is activated. At this time, the electric telescopic rod 212 pushes the two connecting rods 214 to move through the connecting block 213. The two connecting rods 214 drive the two sliders 222 to slide and move closer to each other in the two limiting grooves 221 through the corresponding hinge blocks 224. At this time, the two sliders 222 drive the two fixing rods 223 to move closer to each other, fixing the aluminum rod through cooperation with the support plate 112. Through the reverse operation process, the fixing of the aluminum rod is released, and the aluminum rod is released. After the rod is fixed, the hydraulic cylinder 321 is activated. At this time, the hydraulic cylinder 321 pushes the corresponding support plate 312 to move. The lower support plate 312 drives the corresponding rack 323 to move in the corresponding trapezoidal groove 322. The moving rack 323 drives the gear 325 to rotate through the rotating rod 324. The gear 325 drives another rack 323 to move, thereby driving the upper support plate 312 to move downward. At this time, the two support plates 312 simultaneously drive the two corresponding guide rods 314 to move closer to each other. Under the action of the parallel design of several guide rods 314, it is ensured that the two support plates 312 drive the two cutting blades 313 to move smoothly and cut the aluminum rod. Through the reverse operation process, the two cutting blades 313 are driven to move away from each other.
