Description

Technical Field

[0001] This application relates to the field of shearing equipment, and more particularly to a precious metal electro-hydraulic shearing machine. Background Technology

[0002] With social development and progress, people's living standards and quality of life are getting higher and higher, and the demand for precious metal jewelry is also increasing. As people's aesthetic views continue to improve, it brings a great challenge to the craftsmanship of precious metal processing. The processing of various precious metals is inseparable from the metal cutting process. At present, the precious metal industry often uses tools such as electric saws, cutting machines or pliers to cut precious metals. When using electric saws and cutting machines to cut precious metals, the loss of the cut precious metal material is relatively large. Since precious metals are often expensive, this results in a large economic loss during the cutting process. Summary of the Invention

[0003] In order to reduce the material loss of precious metals when shearing them, this application provides an electric hydraulic shearing machine for precious metals.

[0004] The precious metal electro-hydraulic shearing machine provided in this application adopts the following technical solution: An electric hydraulic shearing machine for precious metals includes a shearing housing, a shearing assembly, and a drive assembly. The shearing assembly includes a shearing frame, two cutters, and a hydraulic drive module. The shearing frame slides vertically and engages with the shearing housing. One cutter is fixedly mounted on the shearing frame, and the other cutter is fixedly mounted on the shearing housing, with the blades of the two cutters facing each other. The hydraulic drive module is disposed inside the shearing housing and is used to drive the shearing frame to move vertically. The drive assembly is disposed in the shearing housing and is used to drive the hydraulic drive module.

[0005] By adopting the above technical solution, when the shearing machine needs to shear precious metals, the precious metal is placed on the surface of the shearing housing, with the position of the precious metal to be sheared aligned with the blades of the two cutters. Then, the drive assembly is activated, which in turn drives the hydraulic drive module. The hydraulic drive module moves the shearing frame vertically towards the shearing housing, thereby causing the shearing frame to move one cutter vertically towards the other cutter until the two cutters complete the shearing of the precious metal. The two cutters, through the shearing drive module, provide the shearing driving force to complete the shearing of the precious metal. The shearing process utilizes a hydraulic drive module that provides stable and powerful driving force, enabling the two cutting blades to steadily and sharply induce shear deformation in the precious metal, thus smoothly cutting it. This reduces material loss during precious metal shearing and improves upon the current practice in the precious metal industry of using tools such as electric saws, cutting machines, or pliers for shearing. Electric saws and cutting machines, in particular, result in significant material loss during shearing, which is often associated with expensive precious metals and leads to substantial economic losses.

[0006] Optionally, the shearing frame is a hollow rectangular frame.

[0007] Optionally, one side of the shearing frame along the vertical direction is a shearing part, which is located outside the shearing housing and is fixedly connected to the cutting blade. The other side of the shearing frame along the vertical direction is a driving part, which is located inside the shearing housing and is connected to the hydraulic drive module. The two sides of the shearing frame along the horizontal direction are sliding parts, and both sliding parts are in sliding cooperation with the shearing housing.

[0008] Optionally, the hydraulic drive module includes a hydraulic cylinder, a hydraulic rod, a return spring, and a hydraulic supply fluid. The hydraulic cylinder is fixedly disposed inside the shear housing. The hydraulic rod slides within the hydraulic cylinder, dividing the interior of the hydraulic cylinder into two independent hydraulic chambers: one is a pressure supply chamber, and the other is a return chamber. The hydraulic rod is fixedly connected to the shear frame. The return spring is located in the return chamber and is used to drive the hydraulic rod to return to its original position. The hydraulic supply fluid is fixedly connected to the hydraulic cylinder, and its outlet communicates with the pressure supply chamber. When the fluid in the hydraulic supply fluid flows into the pressure supply chamber, it pushes the hydraulic rod to slide, thus driving the hydraulic drive module.

[0009] Optionally, the drive assembly includes a drive motor, which is fixedly disposed inside the shear housing and used to drive the hydraulic drive module.

[0010] Optionally, the drive assembly further includes a clutch, which is fixedly disposed inside the shear housing. The input shaft of the clutch is a motor connecting shaft, which is coaxially fixed with the output shaft of the drive motor. The output shaft of the clutch is a hydraulic connecting shaft, which is connected to the hydraulic drive module.

[0011] Optionally, the drive assembly further includes a power adapter and a motor driver. The power adapter is fixedly disposed inside the shear housing and is used to adapt to different power supplies. The motor driver is fixedly disposed inside the shear housing and is used to drive the drive motor.

[0012] Optionally, the shearing housing is fixedly provided with a shearing platform, which is located between the two cutters. The shearing platform has a through-cutting opening, and one of the cutters passes through the shearing opening.

[0013] Optionally, the top of the shear housing is provided with a placement slot for placing materials.

[0014] Optionally, the shear housing is provided with at least two control buttons, at least one of the control buttons is used to control the two cutters to move toward each other, and at least one of the control buttons is used to control the two cutters to move away from each other.

[0015] In summary, this application includes at least one of the following beneficial technical effects: When the shearing machine needs to shear precious metals, the precious metal is placed on the surface of the shearing housing, with the area to be sheared aligned with the blades of the two cutters. The drive assembly then activates the hydraulic drive module, which moves the shearing frame vertically towards the shearing housing. This, in turn, moves one cutter vertically towards the other cutter until both cutters have completed shearing the precious metal. The hydraulic drive module provides stable and powerful shearing force, ensuring the cutters can consistently and sharply induce shear deformation in the precious metal, resulting in a smooth cut. This reduces material loss during precious metal shearing and improves upon the current practice in the precious metals industry, which often uses tools like chainsaws, cutting machines, or pliers. Using chainsaws and cutting machines results in significant material loss, which is a major economic problem given the high cost of precious metals. Attached Figure Description

[0018] The following is in conjunction with the appendix Figures 1a-1c , Figures 2-9 This application will be described in further detail.

[0019] This application discloses an electro-hydraulic shearing machine for precious metals. Refer to Figure 1 and... Figure 2 An electric hydraulic shearing machine for precious metals includes a shearing housing 1, a shearing assembly 2, and a driving assembly 3. The shearing assembly 2 is disposed in the shearing housing 1 and is used to shear precious metals, and the driving assembly 3 is disposed inside the shearing housing 1 and is used to drive the shearing assembly 2 to work.

[0020] Refer to Figure 1. Figure 2 as well as Figure 3The shear housing 1 is rectangular. In this embodiment, the height of the shear housing 1 is set to the vertical direction, and the width of the shear housing 1 is set to the horizontal direction. The shear housing 1 is internally fixed with a clutch fixing plate 11, a hydraulic fixing plate 12, and a fixing frame 13. The top of the shear housing 1 is fixedly fixed with a shearing platform 14, which is located on top of the fixing frame 13. The shearing platform 14 has a through shearing opening 141. The top of the shear housing 1 has a placement groove 15 for placing materials. The bottom of the shear housing 1 is fixedly fixed with multiple foot pads 16, each foot pad 16 being located at a corner of the bottom of the shear housing 1.

[0021] Refer to Figure 1 and Figure 2 The shearing assembly 2 includes a shearing frame 21, two cutters 22, and a hydraulic drive module 23. The shearing frame 21 slides vertically and is fitted to the shearing housing 1. One cutter 22 is located outside the shearing housing 1 and is called the upper cutter 22. The upper cutter 22 is fixedly connected to the shearing frame 21. The other cutter 22 is located inside the shearing housing 1 and is called the lower cutter 22. The lower cutter 22 is fixedly connected to the fixing frame 13, and the cutting edge of the lower cutter 22 passes through the shearing opening 141. The cutting edges of the two cutters 22 are arranged facing each other. The hydraulic drive module 23 is located inside the shearing housing 1 and is used to drive the shearing frame 21 to move vertically. The drive assembly 3 is located in the shearing housing 1 and is used to drive the hydraulic drive module 23.

[0022] Reference Figure 4 In this embodiment, the shearing frame 21 is a hollow rectangular frame. One side of the shearing frame 21 extending in the horizontal direction is the shearing part 211, which is located outside the shearing housing 1 and is fixedly connected to the upper cutter 22. The other side of the shearing frame 21 extending in the horizontal direction is the driving part 212, which is located inside the shearing housing 1 and is connected to the hydraulic drive module 23. The two sides of the shearing frame 21 extending in the vertical direction are the sliding parts 213, which are both slidingly engaged with the shearing housing 1.

[0023] Reference Figures 5 to 7In this embodiment, the hydraulic drive module 23 includes a hydraulic cylinder 231, a hydraulic rod 232, a return spring 233, and a hydraulic supply fluid 234. The hydraulic cylinder 231 is fixedly connected to the interior of the shear housing 1. The hydraulic rod 232 slides within the hydraulic cylinder 231, dividing the interior of the hydraulic cylinder 231 into two independent hydraulic chambers: one is the supply chamber 2311, and the other is the return chamber 2312. The hydraulic rod 232 is fixedly connected to the middle position of the drive unit 212, thereby making the sliding of the shear frame 21 in the vertical direction more stable. The return spring 233 is located in the return chamber 2312 and is used to drive the hydraulic rod 232 to return to its original position. Body 234 is fixedly connected to hydraulic cylinder body 231 and hydraulic fixing plate 12, and the outlet 2341 of hydraulic liquid supply 234 is connected to pressure supply chamber 2311. When the liquid in hydraulic liquid supply 234 flows to pressure supply chamber 2311, the hydraulic rod 232 located on the side of pressure supply chamber 2311 is subjected to greater pressure than the hydraulic rod 232 located on the side of reset chamber 2312. As a result, the hydraulic rod 232 slides towards the side of compression reset chamber 2312, that is, the hydraulic rod 232 slides vertically towards the bottom of shear housing 1. As a result, the hydraulic rod 232 drives the shearing part 211 to move vertically towards the direction of shear housing 1, thereby completing the driving of shear frame 21.

[0024] Reference Figure 8 In this embodiment, the drive assembly 3 includes a drive motor 31 and a clutch 32. The drive motor 31 is disposed inside the shear housing 1 and fixedly connected to one side of the clutch fixing plate 11. The clutch 32 is disposed inside the shear housing 1 and fixedly connected to the other side of the clutch fixing plate 11. The input shaft of the clutch 32 is a motor connecting shaft 321, which is coaxially fixed with the output shaft of the drive motor 31. The output shaft of the clutch 32 is a hydraulic connecting shaft 322, which is connected to the hydraulic supply fluid 234 so that when the hydraulic connecting shaft 322 rotates, the fluid inside the hydraulic supply body flows to the supply chamber 2311.

[0025] Reference Figure 8 In this embodiment, the drive assembly 3 further includes a power adapter 33 and a motor driver 34. The power adapter 33 is fixedly disposed inside the shear housing 1 and is used to adapt to different power supplies. The motor driver 34 is fixedly disposed inside the shear housing 1 and is used to drive the drive motor 31.

[0026] Reference Figure 9 In this embodiment of the application, the shear housing 1 is provided with two control buttons 17. One control button 17 is used to control the two cutters 22 to move toward each other, and the other control button 17 is used to control the two cutters 22 to move away from each other.

[0027] The implementation principle of a precious metal electric hydraulic shearing machine according to an embodiment of this application is as follows: When the shearing machine 100 needs to shear precious metal, the precious metal is placed on the surface of the shearing housing 1, and the position of the precious metal to be sheared is directly opposite the cutting edges of the two cutting blades 22. Then, the drive assembly 3 drives the hydraulic drive module 23 to work. The hydraulic drive module 23 drives the shearing frame 21 to move vertically towards the shearing housing 1, thereby causing the shearing frame 21 to drive the cutting blade 22 to move vertically towards the other cutting blade 22, until the two cutting blades 22 complete the shearing of the precious metal. The two cutting blades 22 are hydraulically controlled. The drive module 23 provides the shearing driving force to complete the shearing of precious metals. The hydraulic drive module 23 provides a stable and powerful driving force, which enables the two cutting blades 22 to stably and sharply cause shearing deformation of the precious metals, thereby cutting the precious metals smoothly. This reduces the material loss of precious metals during shearing and improves the current situation in the precious metals industry where tools such as electric saws, cutting machines, or pliers are commonly used for shearing precious metals. When using electric saws and cutting machines to shear precious metals, the material loss of the sheared precious metals is relatively large, which leads to significant economic losses during shearing, especially since precious metals are often expensive.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
