Description

Technical Field

[0001] This application relates to the field of silver ingot cutting technology, and more particularly to a clamping device for cutting silver ingots. Background Technology

[0002] During the casting process of silver ingots, a silver head, or casting head, often remains at the end of the ingot after casting and needs to be removed through a cutting process. However, during the cutting process, due to the large shearing force, the silver ingot is prone to tilting, flipping, or shifting, resulting in poor cutting effect, uneven cut, and may even cause equipment damage or safety hazards.

[0003] Traditional clamping devices mostly adopt rigid fixed structures, such as clamping bars, buckle clamping devices, and electric vertical telescopic clamping devices. Clamping bars and buckle clamping devices have problems such as long clamping time, need for manual fixing, inconvenient adjustment, and poor adaptability. Electric vertical telescopic clamping devices may damage silver ingots or fail to extend to the required position, requiring irregular adjustments, which seriously affects silver ingot production.

[0004] Therefore, there is an urgent need for a silver ingot cutting and clamping device that is compact, flexible in adjustment, has stable clamping force, and can adapt to complex working conditions, so as to improve cutting accuracy and production efficiency, while reducing operation difficulty and maintenance costs.

[0029] During the silver ingot production process, a silver tip, known as the casting head, often remains at the end of the ingot after casting and needs to be removed through cutting. However, during the cutting process, due to the large shearing force, the silver ingot is prone to tilting, flipping, or shifting, resulting in poor cutting quality, uneven cuts, and even potential equipment damage or safety hazards. Traditional clamping devices mostly use rigid fixed structures, such as clamping bars, snap-fit ​​clamping devices, and electric vertical telescopic clamping devices. Clamping bars and snap-fit ​​clamping devices have problems such as long clamping time, need for manual fixing, inconvenient adjustment, and poor adaptability. Electric vertical telescopic clamping devices may damage the silver ingot or fail to extend to the correct position, requiring periodic adjustments, which seriously affects silver ingot production.

[0030] To address the aforementioned issues, this application provides a clamping device for cutting silver ingots. It utilizes a telescopic cylinder to control the force rod and fulcrum rod to rotate the lever, which, in conjunction with a screw and pressure block, clamps the silver ingot to be cut. The lever structure, composed of the telescopic cylinder, force rod, fulcrum rod, and lever, enables precise control of the pressing point and pressure, allowing for stable pressing of the silver ingot. Furthermore, the pressure block can be flexibly raised and lowered, reducing operational difficulty and maintenance costs.

[0031] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0032] Figure 1 This is a schematic diagram of the structure of a clamping device for cutting silver ingots, as shown in an embodiment of this application.

[0033] See Figure 1 A clamping device for cutting silver ingots, comprising:

[0034] Telescopic cylinder 1, pull rod 2, pad 3, lever 4, screw 5, pressure block 6, template 7, alignment block 8, fixing frame 9, base plate 10, support plate 11, force-bearing rod 12, fulcrum rod 13 and nut 14;

[0035] The support plate 11 is installed on one side of the template 7, and the base plate 10 is set under the support plate 11 to raise the height of the support plate 11 on one side of the template 7. The cylinder body of the telescopic cylinder 1 is installed at an angle on the upper rear side of the support plate 11 to facilitate the telescopic cylinder 1 to exert force.

[0036] A telescopic cylinder 1 has a pull rod 2 mounted on its telescopic rod. The pull rod 2 is made of steel. A fixing frame 9 is mounted on a support plate 11 below the top of the pull rod 2. The fixing frame 9 consists of two symmetrical steel plates. One end of a lever 4 is mounted between the fixing frames 9 via a pivot. The upper end of a force-bearing rod 12 is rotatably mounted on the front end of the pull rod 2 via a pivot, and the other end of the force-bearing rod 12 is movably mounted in the middle of the lever 4. The upper end of a fulcrum rod 13 is movably mounted coaxially with the force-bearing rod 12, and the other end of the fulcrum rod 13 is rotatably mounted on the outer side of the middle of the fixing frame 9. The mounting point of lever 4 between the fixed frames 9 is set after the mounting point of fulcrum rod 13 on the fixed frame 9, and the mounting point of fulcrum rod 13 on the fixed frame 9 is set after the mounting point of force rod 12 on lever 4. According to the lever principle, the greater the distance between the mounting point of lever 4 between the fixed frames 9, the mounting point of force rod 12 on lever 4, and the mounting point of fulcrum rod 13 on the fixed frame 9, the smaller the required extension length of telescopic cylinder 1, and the telescopic cylinder 1 can use less force to pull lever 4 up and down.

[0037] Nut 14 is installed at the front end of lever 4, screw 5 is installed on nut 14, and pressure block 6 is installed at the lower end of screw 5. The height of pressure block 6 can be adjusted by rotating screw 5 so that when lever 4 is horizontal, pressure block 6 can press down on the silver ingot to be cut.

[0038] Alignment block 8 is installed at the front end of template 7. A sliding rod is provided inside template 7, and alignment block 8 is connected to template 7 through the sliding rod, allowing alignment block 8 to move back and forth at the front end of template 7. A cylinder is provided behind alignment block 8, which pushes alignment block 8 to move. After the silver ingot to be cut is conveyed onto template 7, alignment block 8 is pushed to the edge of template 7 to adjust the optimal cutting position of the silver ingot to be cut onto template 7.

[0039] In this application, after the photoelectric switch detects that the silver ingot to be cut has been delivered to the template 7, it controls the cylinder to push the alignment block 8 to move, adjusting the silver ingot to be cut to the optimal cutting position on the template 7. Then, it controls the piston rod of the telescopic cylinder 1 to extend forward, the angle between the force rod 12 and the fulcrum rod 13 decreases, the front end of the lever 4 descends, driving the pressure block 6 to press down the silver ingot to be cut, and at the same time locking the telescopic cylinder 1 to ensure that the upward force of the silver ingot during cutting will not push the lever 4 to move. After cutting is completed, it controls the telescopic cylinder 1 to retract, driving the upper ends of the force rod 12 and the fulcrum rod 13 to move backward, pulling the front end of the lever 4 to rise, so that the pressure block 6 leaves the silver ingot, waiting for the next silver ingot pressing.

[0040] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
