Abstract
Description
Technical Field
[0001] This utility model relates to the field of cutting device technology, and in particular to an automatic cutting machine for producing gold plates. Background Technology
[0002] In the production of solid gold sheets, the cutting process is a crucial step affecting both finished product quality and production efficiency. Existing cutting equipment often employs single-blade, layer-by-layer cutting methods, requiring repeated positioning and feeding operations. This is particularly problematic when dealing with large-sized blanks, where the lengthy layer-by-layer cutting process limits overall processing efficiency. Furthermore, for solid gold sheets, where dimensional accuracy requirements are not particularly stringent, allowing the cutting mechanism to move would significantly increase structural complexity and operating costs, ultimately hindering profitability.
[0003] Meanwhile, the material of the gold plate has a low density and a relatively soft texture. If the fixing effect is not comprehensive during high-speed cutting, the blank is prone to vertical shaking or slight displacement when subjected to force, which can cause problems such as burrs on the cut and dimensional deviations, directly affecting product quality. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides an automatic cutting machine for producing genuine gold plates, which solves some of the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: an automatic cutting machine for producing gold plates, including a processing table and a saw frame. T-slots are provided on the upper and lower inner walls of the saw frame. Saw blades, evenly distributed, are slidably installed within the T-slots. Adjusting screws are threaded to both ends of the saw blades, extending through the T-slots to the outside. Each adjusting screw has a clamping plate, which clamps against the saw frame. A gantry frame is fixedly installed on the upper end of the processing table. An electric push rod is fixedly installed at the middle of the upper end of the gantry frame. A connecting frame is fixedly installed on the upper end of the saw frame. The lower telescopic end of the electric push rod is fixedly connected between the gantry frame and the connecting frame. Guide rods are fixedly installed at both the front and rear ends of the saw frame. Sliding sleeves are slidably fitted onto the outer sides of each guide rod, and these sliding sleeves are fixedly connected to the gantry frame.
[0006] Furthermore, side frames are fixedly installed on the upper end of the processing table near the front and rear sides of the left end of the gantry. Each side frame has multiple sets of evenly distributed lifting grooves. Square bearings are slidably installed inside each lifting groove. Rollers are fixedly installed between the inside of each square bearing. Adjusting screws are rotatably connected to the middle of the upper end of each square bearing. The adjusting screws are threaded through and connected to the upper end of the side frame. The upper end of the blank is limited and fixed by the rollers, and the design of the rollers does not affect its feeding operation.
[0007] Furthermore, two sets of clamping plates are slidably sleeved on the outer side of each roller, and fasteners are threaded through and connected to each clamping plate. The lower ends of the fasteners are pressed against the rollers, further limiting and fixing the upper ends to reduce cutting burrs and other issues that may be caused by vibration. All of them adopt an adjustable design to be suitable for blanks of different sizes.
[0008] Furthermore, a feeding screw is rotatably installed at the lower end of the processing table, in the middle of the left side of the saw frame. The left end of the feeding screw is fixedly connected to a drive motor via a coupling. The drive motor is fixedly installed at the lower end of the processing table. A moving part is threaded onto the outer side of the feeding screw. A push plate is slidably connected in the middle of the inner side of the moving part. A spring is provided between the lower end of the push plate and the inner bottom of the moving part to drive the blank plate to perform automatic feeding operation. At the same time, it avoids the push plate blocking the operator when placing the blank plate on the processing table. The spring design allows the push plate to rise and fall adaptively.
[0009] Furthermore, a sliding groove is provided in the middle of the processing table on the left side of the gantry frame, and the moving part passes through and is slidably connected inside the sliding groove. The upper end of the moving part is flush with the upper surface of the processing table, ensuring the rationality of the structural design.
[0010] Furthermore, the side frame has three adjusting screws threaded through and connected near the left and right sides. The upper end of the processing table has two sets of side plates placed inside the side frame. The side plates are rotatably connected to the adjusting screws on the same side, providing omnidirectional clamping and limiting function and improving its stability.
[0011] The advantages of this utility model are as follows:
[0012] 1. This device, by sliding and adjusting the saw blade spacing and cooperating with multiple sets of synchronous cutting structures, can flexibly adjust the saw blade layout according to the thickness of the gold plate, and realize multi-layer cutting in a single feed. This design reduces the number of repetitive positioning and reciprocating movements required by traditional layer cutting, which helps to shorten the overall processing time of a single blank and greatly improves cutting efficiency. At the same time, it reduces the running time of the electric push rod, ensuring the feasibility and integrity of this technical solution.
[0013] 2. This device adopts a composite structure of roller pressing, side plate end limiting and clamping fixation, which forms multi-dimensional constraints on the blank from the vertical and horizontal directions. This method can effectively disperse the vibration energy of the blank during the cutting process and suppress local shaking or displacement caused by the light material, thereby reducing the probability of quality defects such as burrs and dimensional deviations, and providing reliable mechanical support to ensure cutting accuracy and product consistency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figures 1-4An automatic cutting machine for producing solid gold plates includes a processing table 1 and a saw frame 2. T-slots 3 are provided on both the upper and lower inner walls of the saw frame 2. Evenly distributed saw blades 4 are slidably installed within the T-slots 3. Adjusting screws 5 are threaded to both ends of the saw blades 4, extending through the T-slots 3 to the outer side. Each adjusting screw 5 is equipped with a clamping plate 6, which clamps against the saw frame 2. A gantry frame 7 is fixedly installed on the upper end of the processing table 1. An electric push rod 8 is fixedly installed in the middle, and a connecting frame 9 is fixedly installed at the upper end of the saw frame 2. The lower telescopic end of the electric push rod 8 passes through the gantry frame 7 and is fixedly connected to the connecting frame 9. Guide rods 10 are fixedly installed at both the front and rear ends of the saw frame 2. Sliding sleeves 11 are slidably connected to the outer side of each guide rod 10. The sliding sleeves 11 are fixedly connected to the gantry frame 7. This device drives the saw frame 2, which is used for cutting operations, to move up and down rapidly through the electric push rod 8, thereby achieving rapid up and down movement. The purpose of the saw blade 4 in cutting the blank is to reduce space occupation and lower maintenance costs compared to traditional crank-connecting rod or eccentric wheel transmission mechanisms. It is also better suited for high-dust and humid environments, eliminates oil contamination, and meets rapid response requirements. In cutting scenarios requiring frequent starts and stops and with relatively low blank hardness, this solution can ideally improve cutting efficiency. Furthermore, by turning the adjusting screw 5, the clamping plate 6 can be separated from the saw frame 2, allowing the saw blade 4 to slide and adjust the spacing. After adjustment, turning the screw in the opposite direction tightens the clamping plate 6 against the saw frame 2, thus meeting the customized requirements for different gold sheet thicknesses. It is flexible and practical, and can directly cut a whole blank into the required size, significantly improving cutting efficiency compared to traditional layer-by-layer cutting. It also reduces the running time of the electric push rod 8, ensuring the feasibility and integrity of this technical solution.
[0022] Please see Figures 1-5The upper end of the processing table 1 is fixedly equipped with side frames 12 near the front and rear sides of the left end of the gantry frame 7. Each side frame 12 has multiple evenly distributed lifting grooves 13. Square bearings 14 are slidably installed inside each lifting groove 13. Rollers 15 are fixedly installed between the inside of each square bearing 14. Adjusting screws 16 are rotatably connected to the middle of the upper end of each square bearing 14. Adjusting screws 16 pass through and are threadedly connected to the upper end of the side frame 12. Two sets of clamps 17 are slidably sleeved on the outer side of each roller 15. Fasteners 18 pass through and are threadedly connected to each clamp 17. The fasteners 18... The lower ends are all tightly abutted against the roller 15. A feeding screw 19 is rotatably installed at the lower end of the processing table 1 at the middle of the left side of the saw frame 2. The left end of the feeding screw 19 is fixedly connected to the drive motor 20 through a coupling. The drive motor 20 is fixedly installed at the lower end of the processing table 1. A moving part 21 is threaded onto the outer side of the feeding screw 19. A push plate 22 is slidably connected at the middle of the inner part of the moving part 21. A spring is provided between the lower end of the push plate 22 and the inner bottom of the moving part 21. A slide groove 23 is provided at the middle of the processing table 1 at the left side of the gantry 7. The moving part 21 passes through and is slidably connected inside the slide groove 23. The upper end of the moving part 21 is flush with the upper surface of the processing table 1. Adjusting screws 24 are threaded through and connected to the side frame 12 near both the left and right sides. Two sets of side plates 25 are placed inside the side frame 12 at the upper end of the processing table 1. The side plates 25 are rotatably connected to the adjusting screws 24 on the same side. The formed gold blank is placed on the processing table 1. Rotating the adjusting screw 16 causes the square bearing 14 to slide within the lifting groove 13, causing the roller 15 to abut against the upper end of the blank. The sliding clamp 17 is used to make it fit against both ends of the blank. Tightening the fasteners 18 ensures tight contact between the rollers 15 and the blank. The pair of clamping plates 17 are fixed, and then the adjusting screw 24 is rotated to move the side plate 25, so that the side plate 25 abuts against both ends of the blank, thereby completing the limiting and fixing of the blank. When the drive motor 20 is turned on to drive the feeding screw 19 to rotate, the feeding screw 19 rotates to drive the push plate 22 to move the blank, which can ensure that it moves in a straight line and avoids skewing in subsequent cutting operations. At the same time, the roller 15 and clamping plates 17 can further improve its stability and prevent the light gold plate material from shaking up and down when subjected to force during cutting, thereby improving the cutting quality and the smoothness of the cut.
[0023] Working principle: In use, the formed gold sheet blank is placed on the processing table 1. By rotating the adjusting screw 16, the square bearing 14 slides within the lifting groove 13, causing the roller 15 to abut against the upper end of the blank. The sliding clamp 17 is then used to fit against both ends of the blank. The fasteners 18 are tightened to secure the clamp 17 to the roller 15. Then, the adjusting screw 24 is rotated to move the side plate 25, causing it to abut against both ends of the blank, thus limiting the blank's position. The device is fixed in place. When the drive motor 20 is turned on, it drives the feeding screw 19 to rotate. The rotation of the feeding screw 19 causes the push plate 22 to move the blank, ensuring linear motion and preventing skewing during subsequent cutting operations. Simultaneously, the roller 15 and chuck 17 further enhance stability, preventing the light weight of the gold sheet from causing it to vibrate up and down during cutting. Furthermore, the device uses an electric push rod 8 to drive the saw frame 2, which performs the cutting operation, to move rapidly up and down. The purpose of cutting the blank plate by the rapidly moving saw blade 4 is achieved. Compared with the traditional transmission mechanism using crank connecting rod or eccentric wheel, this device has a simple structure and is easy to install, which can effectively reduce space occupation and reduce use and maintenance costs. At the same time, it is better suited for high dust and humid environments, eliminates oil pollution, and meets the requirements of rapid response. In cutting scenarios that require frequent start and stop and where the blank plate has low hardness, this solution can ideally improve the cutting efficiency. In addition, by turning the adjusting screw 5, the clamping plate 6 can be separated from the saw frame 2, so that the saw blade 4 can be slid to adjust the spacing. After completion, turning it in the opposite direction will clamp the clamping plate 6 against the saw frame 2, thus meeting the customized requirements of different gold plate thicknesses. It is flexible and practical to use, and can directly cut a whole blank plate into the required size. Compared with the traditional layer-by-layer cutting, it further improves the cutting efficiency and reduces the running time of the electric push rod 8, ensuring the feasibility and integrity of this technical solution.
