Abstract
Description
Technical Field
[0001] This utility model relates to the field of gold processing technology, specifically a cutting device for gold processing. Background Technology
[0002] In the field of gold processing, the cutting of small gold blocks or columnar workpieces is a common and critical process. These small gold workpieces are widely used in many industries such as jewelry making, precision electronic component manufacturing, and art and craft creation. Their cutting quality and efficiency directly affect the quality of the final product and production efficiency.
[0003] Currently, existing small gold cutting devices on the market typically use a clamping block to hold one end of the gold workpiece in place when cutting small gold pieces. The operator then manually presses a drive rod to move the cutting blade and cut the workpiece. While this traditional method may meet basic needs for single cutting tasks, its drawbacks become apparent when multiple cuts are required on the same workpiece. During continuous cutting, after each cut, to continue cutting, the operator must first release the clamping block, adjust the workpiece's position so that the part to be cut is accurately positioned under the cutting blade, and then re-clamp the workpiece. This series of cumbersome steps not only consumes a significant amount of time and effort but also increases the operator's workload. Therefore, we propose a gold processing cutting device. Utility Model Content
[0004] The purpose of this invention is to provide a cutting device for gold processing, which solves the problems in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a gold processing cutting device, comprising a cutting frame, a pressure knife, and a bottom knife. A fixed base is fixedly installed at the bottom end of the cutting frame. A drive rod is hinged to one side of the cutting frame near the top. One end of the pressure knife is hinged to one side of the cutting frame. A connecting plate is hinged to one side of the drive rod. The other end of the connecting plate is hinged to the other end of the pressure knife. The bottom knife is fixedly embedded in the other side of the cutting frame. A connecting plate is fixedly installed on one side of the cutting frame. A fixed frame is installed at the top of the connecting plate. A connecting frame is provided inside the fixed frame. A pressure roller is rotatably connected inside the connecting frame. A screw is rotatably connected to the top of the connecting frame through a bearing seat. The screw is threadedly connected to a threaded hole opened at the top of the fixed frame. A knob is fixedly installed at the top of the screw.
[0006] Preferably, the inner wall of the connecting frame is rotatably connected to a rotating shaft via a bearing seat, the pressure roller is fixedly sleeved on the outer wall of the rotating shaft, the front of the fixed frame has a movable groove, the inner wall of the movable groove is slidably connected to a movable block, the other end of the rotating shaft movably passes through one side of the connecting frame and the movable block, and the rotating shaft is rotatably connected to the connecting frame and the movable block via a bearing, and a second knob is fixedly installed on the other end of the rotating shaft.

[0007] Preferably, a limiting slide plate is fixedly installed on the outer wall of the movable block, and a limiting groove is formed on the inner wall of the movable groove. The limiting slide plate and the limiting groove are slidably connected.

[0022] like Figure 1-4As shown, this utility model provides a technical solution: a gold processing cutting device, including a cutting frame 1, a pressure knife 5 and a bottom knife 6. A fixed base 2 is fixedly installed at the bottom end of the cutting frame 1. A drive rod 3 is hinged to one side of the cutting frame 1 near the top. One end of the pressure knife 5 is hinged to one side of the cutting frame 1. A connecting plate 4 is hinged to one side of the drive rod 3. The other end of the connecting plate 4 is hinged to the other end of the pressure knife 5. The bottom knife 6 is fixedly embedded in the other side of the cutting frame 1. A connecting plate 4 is fixedly installed on one side of the cutting frame 1. A fixed frame 7 is installed at the top of the connecting plate 4. A connecting frame 9 is provided inside the fixed frame 7. A pressure roller 12 is rotatably connected inside the connecting frame 9. A screw 10 is rotatably connected to the top of the connecting frame 9 through a bearing seat. The screw 10 is threadedly connected to a threaded hole opened at the top of the fixed frame 7. A knob 11 is fixedly installed at the top of the screw 10.
[0023] Furthermore, the inner wall of the connecting frame 9 is rotatably connected to the rotating shaft 14 via a bearing seat, the pressure roller 12 is fixedly sleeved on the outer wall of the rotating shaft 14, the front of the fixed frame 7 is provided with a moving groove 18, the inner wall of the moving groove 18 is slidably connected to the moving block 17, the other end of the rotating shaft 14 movably passes through one side of the connecting frame 9 and the moving block 17, and the rotating shaft 14 is rotatably connected to the connecting frame 9 and the moving block 17 via a bearing, and the other end of the rotating shaft 14 is fixedly installed with a knob 15;
[0024] The knob 15 allows personnel to easily rotate the shaft 14, thus facilitating operation.
[0025] Furthermore, a limiting slide plate 19 is fixedly installed on the outer wall of the movable block 17, and a limiting slide groove 20 is opened on the inner wall of the movable groove 18, with the limiting slide plate 19 and the limiting slide groove 20 slidably connected.
[0026] By setting the limiting slide plate 19 and the limiting slide groove 20, the moving block 17 can be limited, so that the moving block 17 can be fixed and slide in the moving groove 18.
[0027] Furthermore, the fixing frame 7 is detachably connected to the fixing plate 16 by bolts.
[0028] Furthermore, the outer wall of the pressure roller 12 is provided with three grooves 13, and the width of the three grooves 13 increases sequentially from left to right;
[0029] By incorporating multiple grooves 13 of varying sizes, the pressure roller 12 can press gold columnar workpieces of different specifications, reducing limitations in its application.
[0030] Furthermore, a support pad 8 is fixedly installed at the bottom of the inner wall of the fixed frame 7, and the support pad 8 is made of Teflon.

[0032] Specifically, in the above technical solution, when using the gold processing cutting device, small gold block or columnar workpieces are directly passed through the fixed frame 7, and the area to be cut is extended between the pressure knife 5 and the bottom knife 6. Then, the knob 11 is turned, causing the screw 10 to rotate. The screw 10 causes the connecting frame 9 to move downwards. The connecting frame 9 drives the pressure roller 12 downwards via the rotating shaft 14, ultimately pressing the pressure roller 12 against the gold workpiece. Then, one hand holds the knob 2 15, and the other hand directly presses the drive rod 3. The drive rod 3 drives the pressure knife 5 downwards via the connecting plate 4, ultimately causing the pressure knife 5 and the bottom knife 6 to press against the gold workpiece. After the workpiece is cut, when it is necessary to continue cutting the gold workpiece, simply turn knob 15. Knob 15 will drive the pressure roller 12 to rotate via shaft 14. The pressure roller 12 will then drive the gold workpiece to continue moving towards the pressure knife 5, thus allowing for continuous cutting of the gold workpiece. Through the above structure, the pressure roller 12 can be pressed and fixed during the cutting process of the gold workpiece. At the same time, when it is necessary to continue cutting the gold workpiece, the pressure roller 12 can be quickly rotated to drive the gold workpiece towards the pressure knife 5, allowing the gold workpiece to extend continuously. This allows for rapid completion of multiple cuts, improving cutting efficiency.
