Description

Technical Field

[0001] The utility model relates to the technical field of shearing machine equipment, and particularly relates to a hydraulic shearing machine. Background Art

[0002] In the metal processing industry, as an important mechanical equipment, the hydraulic shearing machine is widely used in the processing of materials such as metal sheets, bars, and pipes. Its characteristics of high efficiency, energy saving, high cutting precision, and simple operation make the hydraulic shearing machine the preferred equipment for many metal processing enterprises. However, in the existing hydraulic shearing machine technology, there are still some problems to be solved urgently, especially in the aspect of material fixation.

[0003] During the shearing process of traditional hydraulic shearing machines, the stability of materials often depends on the experience and skills of operators. However, due to the influence of various factors on the material during transportation and positioning, such as the accuracy of the conveying mechanism and the proficiency of operators, the material is prone to skew during shearing. This not only affects the shearing precision and product quality but also may lead to equipment damage and safety accidents. Moreover, as shown in the conventional hydraulic pliers diagram Figure 1 When in use, the hydraulic pliers body needs to be fixed by hand or by using a bracket or held by an operator, and then the material is placed in the hydraulic pliers body for shearing. This method has low efficiency during operation and requires double fixation of the hydraulic pliers body and the material to ensure the safety and stability of the operation, reducing the operation efficiency. Content of the Utility Model

[0004] In order to solve the above problems, the embodiment of the utility model provides a hydraulic shearing machine capable of fixing materials during shearing.

[0005] The embodiment of the utility model adopts the following specific technical solutions to achieve the above purpose: A hydraulic shearing machine includes a base, a material receiving bin is arranged on the base, a shearing module is arranged on one side of the material receiving bin, a hydraulic power assembly connected to the shearing module is arranged on one side of the base, the shearing module includes a mounting frame, a connecting shaft is arranged at the bottom of the mounting frame, a tool rest is arranged on the connecting shaft, a hydraulic cylinder for driving the tool rest to rotate is arranged on one side of the mounting frame, and a positioning device for clamping the material is arranged on one side of the tool rest.

[0006] As a further improvement of the above technical solution:

[0007] The positioning device includes a support plate, and a pressing arm for fixing the material is arranged above the support plate.

[0008] One end of the pressing arm is rotatably connected to the connecting shaft, and the other end extends above the support plate. A pressing cylinder is arranged between the upper part of the pressing arm and the mounting frame.

[0009] A pressing plate is arranged at the lower part of the pressing arm. A limiting platform that abuts against the outer edge of the material is arranged at the lower part of the pressing plate. A clamping boss that abuts against the inner edge of the material is arranged on the support plate.

Detailed implementation mode

[0021] The preferred implementation modes of the present utility model will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these implementation modes are only used to explain the technical principle of the present utility model and are not intended to limit the protection scope of the present utility model.

[0022] Embodiment 1

[0023] As Figure 2-3 shown, the hydraulic shearing machine of this embodiment includes a base 1, a material receiving bin 2 is provided on the base 1, a shearing module is installed on one side of the material receiving bin 2, a hydraulic power assembly connected to the shearing module is provided on one side of the base 1, the shearing module includes a mounting frame 3, a connecting shaft 4 is provided at the bottom of the mounting frame 3, a tool rest 5 is installed on the connecting shaft 4, one end of the tool rest 5 is rotatably connected to the connecting shaft 4, a cutting tool is installed at the lower part of the tool rest 5, a hydraulic cylinder 6 for driving the tool rest 5 to rotate is installed on one side of the mounting frame 3, and both ends of the hydraulic cylinder 6 are hinged to the mounting frame 3 and the tool rest 5 respectively, and a positioning device for clamping the material is provided on one side of the tool rest 5.

[0024] The positioning device includes a support plate 7, the support plate 7 is located on the upper surface of the base 1 and its end is flush with the material receiving bin 2, a pressing arm 8 for fixing the material is provided above the support plate 7, during operation, the material is placed on the support plate 7, and during shearing, the material is first pressed by the positioning device and then the shearing operation is carried out, so as to avoid the material from being skewed.

[0025] One end of the pressing arm 8 is rotatably connected to the connecting shaft 4, the other end extends above the support plate 7, and a pressing cylinder 9 is provided between the upper part of the pressing arm 8 and the mounting frame 3. First, the pressing arm 8 is pressed down by the pressing cylinder 9 and then the tool rest 5 is pressed down by the hydraulic cylinder 6 for the shearing operation.

[0026] A pressing plate 10 is provided at the lower part of the pressing arm 8, a limiting platform 11 abutting against the outer edge of the material is provided at the lower part of the pressing plate 10, a clamping boss 12 abutting against the inner edge of the material is provided on the support plate 7, and the design of the limiting platform 11 and the clamping boss 12 can clamp the material on both the inner and outer sides of the material. Compared with the pressing method, it can improve the limitation of the material and avoid the material from sliding during shearing.

[0027] The number of the limiting platforms 11 is multiple and they are distributed in a stepped manner. The design of the multiple limiting platforms 11 can carry out clamping operations for materials of different sizes and is suitable for shearing operations of various materials.

[0028] Example 2

[0029] The same points as in Example 1 are not described in detail. The difference is that the active drive of the clamping arm is cancelled, so that the clamping arm 8 moves with the tool holder 5, reducing one driving source and saving equipment cost investment. Figure 4-5 As shown, a connecting rod 13 is provided on one side of the clamping arm 8, one end of the connecting rod 13 is connected to the clamping arm 8, and the other end is provided with a slider 14 slidably connected to the tool holder 5. A groove 15 used in conjunction with the slider 14 is provided on the side wall of the tool holder 5, and a tightening spring 16 located above the slider 14 is provided in the groove 15. When working, the slider 14 slides on the slide 15. Since the tool holder 5 is rotatably connected to the connecting shaft 4, the operating trajectory of the connecting rod 13 is arc-shaped. Therefore, the width of the slide 15 will be larger than the width of the slider 14 to meet the arc-shaped motion trajectory of the slider 14. When working, in order to avoid the slider in the groove 15 Deflection occurs, which affects the linear pressure of the clamping spring 16. A pressure block is designed at the end of the clamping spring 16. An arc groove is provided on the lower surface of the pressure block. The diameter of the arc groove is slightly larger than the diameter of the slider 14. The slider can be laterally displaced in the arc groove according to the running trajectory, but will not be separated from the arc groove. The clamping spring 16 can shrink after the clamping arm 8 abuts against the material, providing a avoidance for the continued fall of the tool holder 5, thereby completing the shearing operation. When the tool holder 5 rises, the clamping arm will be driven to rise as well. The driving operation of the shearing and clamping devices can be realized by one hydraulic cylinder, which simplifies the equipment structure and saves the equipment manufacturing cost.
