Description

Technical Field

[0001] This utility model belongs to the field of gold jewelry technology, specifically a gold jewelry fixed-distance cutting device. Background Technology

[0002] In the gold jewelry processing industry, fixed-distance cutting is a key process for the mass production of standardized parts such as chain links, ring blanks, and earring components. Its core requirement is to ensure that the workpieces are of consistent size and the cut is flat and without tilt after cutting, so as to reduce the workload of subsequent polishing and finishing processes and reduce the loss of gold raw materials (gold is a high-value precious metal, and even a 0.1mm size error may lead to waste of raw materials or scrap of products).

[0003] In actual use, after the operator measures and marks the material with calipers, they manually push it to the cutting position and then cut it with a small cutting machine. This method is limited by the precision of manual operation (the positioning error is usually ≥0.1mm), and gold is soft. When pushing it manually, uneven force can easily cause the material to tilt or shift. After cutting, the cut often has problems such as tilted cuts and inconsistent lengths. Afterwards, more than 30% of the time needs to be spent on corrections, and the material loss rate is as high as 5%-8%. At the same time, the existing clamping components are mostly fixed-size hard claws or unidirectional positioning structures, which cannot adapt to materials with different diameters (such as 0.3-5mm gold wire) or cross-sectional shapes (round, square). The material is prone to "eccentricity" phenomenon, which causes the blade to be non-perpendicular to the material axis during cutting.

[0004] Therefore, this utility model provides a gold jewelry fixed-distance cutting device. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the problems mentioned in the background technology, a gold jewelry fixed-distance cutting device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A gold jewelry fixed-distance cutting device of this utility model includes a housing; side plates are fixedly installed on both sides of the top of the housing, a gantry frame is fixedly installed on the top of the housing, a conveyor belt assembly is provided on the top of the inner wall of the housing, a straightening mechanism is provided on both sides of the top of the housing, and a limit component is provided on both sides of the top of the housing near the straightening mechanism; a pressing mechanism is provided on the top of the inner wall of the gantry frame, and a cutting mechanism is provided on the inner wall of the gantry frame; A measuring mechanism is provided on the top of the housing; the correction mechanism includes a cylinder, a push plate, and an inclined plate. Two sets of cylinders are provided, and the two sets of cylinders are fixedly installed on both sides of the top of the housing. The output end of the cylinder is fixedly installed with the push plate, and the two sides of the push plate are fixedly installed with the inclined plate. The cylinder can correct the position of the jewelry by pushing the push plate. At the same time, because the cylinder pushes smoothly, the accuracy of the push plate can be improved. The cooperation between the push plate and the inclined plate can center and align the jewelry, so that the cut can be kept smooth.

[0007] Preferably, the limiting component includes a fixing block and a guide plate. The fixing block is fixedly installed on both sides of the top of the housing near the cylinder. The inner wall of the fixing block near the push plate is slidably installed with the guide plate. The side of the guide plate away from the fixing block is fixedly installed with the push plate. In this solution, the cooperation between the fixing block and the guide plate can provide guidance for the push plate and prevent longitudinal pressure from being applied to the cylinder, causing it to jam.

[0008] Preferably, the pressing mechanism includes an electric push rod, a cross plate, and guide blocks. The electric push rod is fixedly installed on the top of the inner wall of the gantry frame, and the output end of the electric push rod is fixedly installed with the cross plate. The guide blocks are fixedly installed on both sides of the inner wall of the gantry frame, and the two sides of the cross plate are slidably installed with the guide blocks. In this scheme, the cooperation between the electric push rod and the cross plate can achieve the adjustment of the descent depth of the cutting mechanism by the user's precise control, and the guide blocks can provide guidance for the cross plate.

[0009] Preferably, the cutting mechanism includes a dovetail groove, a cutter, and a vibration motor. The dovetail groove is formed at the bottom of the horizontal plate, and the cutter is slidably installed with the horizontal plate through the dovetail groove. There are gaps between the two sides of the cutter and the horizontal plate. In this design, the dovetail groove allows the cutter to slide at the bottom of the horizontal plate without falling off. The combination of the cutter and the vibration motor allows the cutter to move through the vibration generated by the vibration motor, thereby achieving cutting. At the same time, the vibration cutting method can cause less damage to the gold.

[0010] Preferably, the measuring mechanism includes a U-shaped frame, a scale plate, and a moving block. The U-shaped frame is fixedly installed on the top of the fixed block, and the inner side of the U-shaped frame is fixedly installed with the scale plate. The moving block is fixedly installed on the top of the push plate, and the moving block is located on the surface of the scale plate and slidably connected to the scale plate. In this scheme, the combined use of the U-shaped frame, the scale plate, and the moving block allows the user to clearly observe the distance the push plate moves when adjusting its position, thereby enabling the push plate to be quickly pushed to the appropriate angle during cutting.

[0011] Preferably, a roller is provided on the side of the push plate away from the cylinder. In this design, the roller can prevent friction between the jewelry and the push plate by rotating itself when the cylinder positions the jewelry, thereby preventing the gold from being worn away during transportation.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The gold jewelry fixed-distance cutting device of this utility model, through the arrangement of a cylinder, a push plate, an inclined plate, a fixed block and a guide plate, enables the cylinder to push the push plate to correct the position of the jewelry. At the same time, because the cylinder pushes smoothly, the accuracy of the push plate can be improved. The cooperation between the push plate and the inclined plate can center and align the jewelry, so that the cut can be kept smooth. The cooperation between the fixed block and the guide plate can provide guidance for the push plate and prevent longitudinal pressure from being applied to the cylinder and causing it to jam.

[0014] 2. The gold jewelry fixed-distance cutting device of this utility model, through the arrangement of an electric push rod, a horizontal plate, a guide block, a dovetail groove, a cutter, and a vibration motor, allows the electric push rod and the horizontal plate to work together to adjust the descent depth of the cutting mechanism through precise user control. The guide block provides guidance for the horizontal plate, and the dovetail groove allows the cutter to slide at the bottom of the horizontal plate without falling off. The cutter and the vibration motor work together to move the cutter through the vibration generated by the vibration motor, thereby achieving cutting. At the same time, the vibration cutting method can cause less damage to the gold. Attached Figure Description

Measuring mechanism 9; Correction mechanism 5 includes cylinder 51, push plate 52, and inclined plate 53. Two sets of cylinders 51 are provided, and the two sets of cylinders 51 are fixedly installed on both sides of the top of the housing 1. The output end of the cylinder 51 is fixedly installed with the push plate 52, and both sides of the push plate 52 are fixedly installed with the inclined plate 53. Limiting assembly 6 includes fixing block 61 and guide plate 62. The fixing block 61 is fixedly installed on both sides of the top of the housing 1 near the cylinder 51. The inner wall of the fixing block 61 near the push plate 52 is slidably installed with the guide plate 62. 2. The side away from the fixed block 61 is fixedly installed with the push plate 52. The pressing mechanism 7 includes an electric push rod 71, a horizontal plate 72, and a guide block 73. The electric push rod 71 is fixedly installed on the top of the inner wall of the gantry frame 3. The output end of the electric push rod 71 is fixedly installed with the horizontal plate 72. The guide block 73 is fixedly installed on both sides of the inner wall of the gantry frame 3. The two sides of the horizontal plate 72 are slidably installed with the guide block 73. The cutting mechanism 8 includes a dovetail groove 81, a cutter 82, and a vibration motor 83. The dovetail groove 81 is opened at the bottom of the horizontal plate 72. The cutter... The cutter 82 is slidably installed on the horizontal plate 72 through the opening of the dovetail groove 81. There is a gap between the two sides of the cutter 82 and the horizontal plate 72. The measuring mechanism 9 includes a U-shaped frame 91, a scale plate 92 and a moving block 93. The U-shaped frame 91 is fixedly installed on the top of the fixed block 61. The inner side of the U-shaped frame 91 is fixedly installed on the scale plate 92. The moving block 93 is fixedly installed on the top of the push plate 52. The moving block 93 is located on the surface of the scale plate 92 and is slidably connected to the scale plate 92. A roller is provided on the side of the push plate 52 away from the cylinder 51.

[0025] like Figures 1 to 4As shown, cylinder 51 can correct the position of jewelry by pushing push plate 52. Simultaneously, the smooth movement of cylinder 51 improves the accuracy of push plate 52. The cooperation between push plate 52 and inclined plate 53 can center and align the jewelry, ensuring a smooth cut. The cooperation between fixing block 61 and guide plate 62 provides guidance for push plate 52, preventing longitudinal pressure from causing cylinder 51 to jam.

The cooperation between the U-shaped frame 91, the measuring plate 92 and the moving block 93 allows the user to clearly observe the distance the push plate 52 moves when adjusting its position, so that the push plate 52 can be quickly pushed to the appropriate angle during cutting. When the cylinder 51 positions the jewelry, the roller can prevent friction between the jewelry and the push plate 52 by its own rotation, thereby preventing the gold from being worn away during transportation.

[0026] Working principle: During operation, the machine housing 1 is first placed on a flat surface. Then, the user places the gold jewelry on the surface of the conveyor belt assembly 4 and starts the conveyor belt assembly 4 to transport the gold to one side. During the transport process, the user can activate the cylinder 51 to push the push plate 52 towards the center, so that the push plate 52 pushes the jewelry to the center position and keeps the jewelry neat. When the jewelry moves to the bottom of the gantry 3, the user first activates the vibration motor 83 to generate vibration. The vibration is then transmitted to the cutter 82 through the horizontal plate 72. Since there is a gap between the cutter 82 and the horizontal plate 72, the cutter 82 can continuously sway back and forth when subjected to vibration. Then, the electric push rod 71 is activated to push the horizontal plate 72 downward. The horizontal plate 72 will then drive the cutter 82 down until the cutter 82 contacts the jewelry and cuts it. After the cutting is completed, the conveyor belt assembly 4 is restarted to continue transporting until the jewelry moves to the set length, and then it is cut again.
