DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0036] A welding device for gold jewelry processing, see Figure 1-Figure 3 , including a welding box 1, two left and right box doors 2 that can be rotated forward and opened are hinged on the front side of the welding box 1, a melting head 3 is embedded on the top of the welding box 1, and the melting head 3 is a high-temperature gun for melting gold. Two upper and lower linear slide rails 12 are installed on the inner walls of the left and right sides of the welding box 1, and four linear slide rails 12 are slidably connected with linear sliders 13, and a push-pull frame 4 is connected between the four linear sliders 13. A shaking mechanism is provided in the push-pull frame 4, and a melting bin 5 is connected to the shaking mechanism. The shaking mechanism can drive the melting bin 5 to shake 360 ​​degrees. Two push plates 7 are symmetrically slidably provided in the melting bin 5, and a driving mechanism is provided outside the melting bin 5 for driving the two push plates 7 to approach each other to extrude the melted gold. The melting bin 5 is provided with a cooling mechanism for cooling the melted gold.

[0037] First, the box door 2 is rotated forward to open, and then the push-pull frame 4 is pulled forward to drive the melting chamber 5 to move forward from the welding box 1, and then the gold to be welded is placed in the melting chamber 5, and then the push-pull frame 4 is pushed backward into the welding box 1, so as to move the melting chamber 5 back into the welding box 1, and then the box door 2 is closed backward to seal the welding box 1, and the melting head 3 is controlled to work to heat-melt the gold in the melting chamber 5, and the shaking mechanism is controlled to work to drive the melting chamber 5 to shake 360 ​​degrees, so that the gold changes position in the melting chamber 5, ensuring that the gold can be evenly melted by the melting head 3, improving the gold melting effect and efficiency, and effectively solving the problem of local overheating or insufficient melting at the edge during the gold melting process. After the gold is completely melted, the control driving mechanism drives the two push plates 7 to approach each other to extrude the melted gold, and controls the cooling mechanism to work. The cooling mechanism can cool the melted gold evenly from top to bottom, reduce the temperature difference between the upper and lower parts of the gold, make the cooling speed of the upper and lower parts of the gold consistent, improve the cooling and shaping effect and efficiency of the gold, and reduce the risk of defects such as deformation and cracks when the gold is cooled and shaped. Therefore, the device realizes uniform heating of the gold and uniform cooling of the melted gold from top to bottom, which significantly improves the welding quality and efficiency of the gold jewelry. When it is necessary to take out the gold nuggets that have been cooled and shaped in the melting chamber 5, the control driving mechanism drives the two push plates 7 to move away from each other.

[0038] See also Figure 3-Figure 5The shaking mechanism includes a fixed plate 61 installed in the push-pull frame 4, a universal joint 62 is installed at the bottom of the fixed plate 61, a connecting frame 63 is connected to the universal joint 62, and the connecting frame 63 is in an X-shape. Ball joints 64 are installed around the top of the connecting frame 63 and around the bottom of the melting bin 5. The two corresponding ball joints 64 are connected by a connecting rod 65, and the connecting rod 65 is connected to the ball on the ball joint 64. A pulling component for pulling the connecting frame 63 to shake 360 ​​degrees is provided in the push-pull frame 4. The pulling component includes an electric rotating disk 66 installed at the bottom of the inner side of the push-pull frame 4. The electric rotating disk 66 includes a driving motor, a rotating shaft and a disc. The rotating shaft is rotatably connected to the bottom of the inner side of the push-pull frame 4, and the disc is connected to the top of the rotating shaft. The driving motor is installed at the bottom of the push-pull frame 4, and the output shaft of the driving motor is connected to the bottom end of the rotating shaft. The driving motor can drive the rotating shaft to drive the disc to rotate. A sliding groove is opened on the top of the disc, and a sliding block 67 is slidably connected in the sliding groove. A ball joint 68 is installed on the top of the sliding block 67. The ball joint 68 is connected to the connecting frame 63 through a connecting rod 69. The connecting rod 69 is connected to the ball of the ball joint 68. A spring 610 is connected between the sliding block 67 and the disc on the electric rotating disc 66. A pushing member for pushing the sliding block 67 to move away from the central axis of the disc is provided at the bottom inner side of the push-pull frame 4. The pushing member includes two electric slide rails 613 symmetrically installed at the bottom inner side of the push-pull frame 4. A cone disk 612 is connected between the sliders of the two electric slide rails 613. The cone disk 612 is slidably mounted on the rotating shaft of the electric rotating disc 66. A contact rod 611 is connected to the bottom of the sliding block 67, and the contact rod 611 contacts the cone disk 612.

[0039] When the melting bin 5 needs to be shaken, the electric slide rail 613 is first controlled to drive the cone disk 612 to move upward. The cone disk 612 moves upward to push the contact rod 611 and the sliding block 67 to move away from the center axis of the disk. The spring 1 610 is compressed accordingly. The sliding block 67 moves away from the center axis of the disk and pulls the connecting frame 63 to swing to a tilted state through the ball joint 2 68 and the connecting rod 2 69. Then the electric rotating disk 66 is controlled to rotate. The electric rotating disk 66 rotates to drive the sliding block 67 to rotate. The sliding block 67 rotates to pull the connecting frame 63 to shake 360 ​​degrees through the ball joint 2 68 and the connecting rod 2 69. The connecting frame 63 shakes 360 degrees and drives the melting bin 5 to shake 360 ​​degrees through the ball joint 1 64 and the connecting rod 1 65, so that the gold changes its position in the melting bin 5, ensuring that the gold can be evenly melted by the melting head 3, improving the gold melting effect and efficiency, and effectively solving the problem of local overheating or insufficient melting at the edge during the gold melting process. When there is no need to shake the melting bin 5, the electric slide rail 613 is controlled to drive the cone disk 612 to move downward. Under the reset action of the spring 1 610, the sliding block 67 is pushed to move with the contact rod 611 toward the center axis of the disk. The sliding block 67 moves toward the center axis of the disk and pulls the connecting frame 63 back to a horizontal state through the ball joint 2 68 and the connecting rod 2 69, thereby keeping the melting bin 5 in a horizontal state.

[0040] See also Figure 6 The driving mechanism includes two stepper motors 82 respectively installed on the outer walls of the front and rear sides of the melting bin 5. There are slide grooves on the front and rear sides of the top of the melting bin 5. Two left and right pull rods 81 are slidably connected in the slide grooves. The pull rod 81 is L-shaped. The pull rod 81 is connected to the push plate 7 on the same side as it. The output shafts of the two stepper motors 82 are connected to winding wheels 83. The two winding wheels 83 are respectively located in the two slide grooves. A pull rope 84 is wound around the winding wheel 83. The two ends of the pull rope 84 are respectively connected to the left and right pull rods 81. A spring 85 is connected between the pull rod 81 and the melting bin 5.

[0041] The stepper motor 82 is controlled to drive the winding wheel 83 to rotate and reel in the pull rope 84, and the pull rods 81 on the left and right sides are pulled closer to each other through the pull rope 84, so that the spring 2 85 is compressed, thereby driving the two push plates 7 to move closer to each other to extrude the molten gold, thereby reducing the waste caused by the strong fluidity of gold after it is melted into liquid state; the stepper motor 82 is controlled to drive the winding wheel 83 to reverse and release the pull rope 84, and under the reset action of the spring 2 85, the pull rods 81 on the left and right sides can be pushed away from each other with the two push plates 7, so as to facilitate the subsequent removal of the cooled and formed gold.

[0042] See also Figure 7-Figure 10The cooling mechanism includes two L-shaped bin covers 91 slidingly arranged on the top of the melting bin 5, and S-shaped tubes 92 are embeddedly installed on the left and right sides of the bottom of the melting bin 5 and the L-shaped bin cover 91. A driving assembly for driving the two L-shaped bin covers 91 to open and close is provided at the lower part of the melting bin 5, and the driving assembly includes a rodless cylinder 99 and a U-shaped push plate 910. A through groove 98 is opened at the bottom of the melting bin 5, and two rodless cylinders 99 are installed in the through groove 98. The through groove 98 is slidably connected with the left and right U-shaped push plates 910, and the sliders on the two rodless cylinders 99 are respectively connected to the two U-shaped push plates 910, and the two U-shaped push plates 910 are respectively connected to the two L-shaped bin covers 91. A liquid injection pipe 93 is connected between the front sides of the two S-shaped tubes 92 on the melting bin 5. A drain pipe 94 is connected between the rear sides of the two S-shaped tubes 92 on 5, and the injection pipe 93 and the drain pipe 94 are both extended to the outside of the melting bin 5. The front and rear ends of the S-shaped tube 92 on the melting bin 5 are both connected with a docking pipe 95, and the docking pipe 95 is extended to the outside of the melting bin 5. The front and rear ends of the S-shaped tube 92 on the L-shaped bin cover 91 are both connected with a docking pipe 2 96, and the end of the docking pipe 2 96 is connected with a docking joint 97, and the docking joint 97 is extended to the outside of the L-shaped bin cover 91. When the two L-shaped bin covers 91 are close to each other, the docking joint 97 is driven to move and dock with the docking pipe 1 95 on the same side. A sealing ring is connected inside the docking joint 97 to seal the gap between the docking joint 97 and the docking pipe 1 95 to prevent leakage of coolant. The L-shaped bin cover 91 is spaced apart from the front to the back with heat dissipation ports.

[0043] The rodless cylinder 99 is controlled to drive the two U-shaped push plates 910 to approach each other, which can drive the two L-shaped bin covers 91 to approach each other and close. When the two L-shaped bin covers 91 approach each other, the docking joint 97 is driven to move and dock with the docking pipe 1 95 on the same side. The injection pipe 93 is connected to the infusion device through a hose, and the discharge pipe 94 is connected to the hose. The infusion device is controlled to inject the coolant into the S-shaped pipe 92 at the bottom of the melting bin 5 through the injection pipe 93. The coolant in the S-shaped pipe 92 on the melting bin 5 then flows into the S-shaped pipe 92 on the L-shaped bin cover 91 through the docking pipe 1 95 and the docking pipe 2 96. The coolant in the S-shaped pipe 92 on the L-shaped bin cover 91 then flows back to the S-shaped pipe 92 on the melting bin 5. The coolant in the S-shaped pipe 92 at the bottom of the melting bin 5 is discharged outward through the discharge pipe 94, so that the coolant in the S-shaped pipe 92 circulates. By circulating the coolant in the S-shaped tube 92 at the bottom of the melting chamber 5 and in the S-shaped tube 92 on the L-shaped chamber cover 91, the melted gold is cooled evenly from top to bottom, the temperature difference between the upper and lower parts of the gold is reduced, and the cooling speed of the upper and lower parts of the gold is made consistent, thereby improving the cooling and shaping effect and efficiency of the gold and reducing the risk of defects such as deformation and cracks when the gold is cooled and shaped. After the gold is cooled and shaped, the rodless cylinder 99 is controlled to drive the two U-shaped push plates 910 away from each other, thereby driving the two L-shaped chamber covers 91 away from each other and opening. When the two L-shaped chamber covers 91 are away from each other, the docking joint 97 is driven to move and reset and to disengage the docking pipe 1 95 on the same side thereof.

[0044] See also Figure 11-Figure 12A feeding mechanism for feeding borax into the melting bin 5 is provided on the top of the fusion welding box 1, and the feeding mechanism includes a storage box 101 embedded in the top of the fusion welding box 1, and the storage box 101 is located on the right side of the melting head 3. The storage box 101 is designed to be large at the top and small at the bottom. A box cover that can be rotated upward to open is hinged on the top of the storage box 101. An L-shaped material guide channel 109 is slidably sleeved on the lower side of the outside of the storage box 101. The material guide channel 109 is located in the fusion welding box 1, and a discharge port 106 is opened at the lower part of the left side of the storage box 101. The material guide channel 109 is connected to the discharge port 106 after moving up. The inner bottom of the storage box 101 is designed to be low on the left and high on the right, so that the borax in it can be smoothly discharged to the left. A lifting frame is connected to the top of the material guide channel 109 103, four spring threes 105 are connected at intervals between the top of the lifting frame 103 and the top of the inner side of the fusion welding box 1, four guide rails 102 for guiding the lifting frame 103 are installed at intervals on the top of the inner side of the fusion welding box 1, and the four spring threes 105 are respectively located in the four guide rails 102, and a vibration motor 104 is installed at the bottom of the inner side of the lifting frame 103. The left side of the material guiding channel 109 is connected to a hollow circular ring 107 with an open bottom design, and an annular filter screen 108 is connected to the hollow circular ring 107. The annular filter screen 108 and the hollow circular ring 107 are all slidably mounted on the outside of the melting head 3, and the material guiding channel 109, the hollow circular ring 107 and the annular filter screen 108 are all installed in an inclined manner with the left side low and the right side high, so that the borax can be smoothly discharged from the lower left side.

[0045] During the melting operation of gold, it is necessary to add an appropriate amount of borax as a flux to prevent gold from oxidizing and promote uniform melting of gold. First, pour the borax into the storage box 101, and then control the vibration motor 104 to work. The operation of the vibration motor 104 can make the lifting frame 103 drive the L-shaped material guide channel 109 to shake up and down. After the L-shaped material guide channel 109 moves up, it is connected with the discharge port 106. The borax in the storage box 101 is then discharged into the material guide channel 109 through the discharge port 106. After the L-shaped material guide channel 109 moves down, it blocks the discharge port 106. In this way, the borax in the storage box 101 can be intermittently discharged into the material guide channel 109, so that intermittent feeding can be achieved to avoid excessive feeding. The borax in the material guide channel 109 then enters the hollow ring 107, and then is dropped downward into the melting bin 5 through the annular filter screen 108, thereby realizing automatic feeding of the borax. The material guide channel 109 vibrates up and down, driving the hollow ring 107 and the annular filter screen 108 to vibrate up and down, thereby realizing shaking feeding and reducing the risk of blockage.

[0046] See also Fig.12The right side of the bottom of the inner side of the material guiding channel 109 is connected with a protrusion 14 at intervals, and the protrusion 14 is located directly below the material storage box 101. When the material guiding channel 109 moves upward, it drives the protrusion 14 to move upward and hit the bottom of the material storage box 101, so that the bottom of the material storage box 101 vibrates, so that the borax in the material storage box 101 can be quickly discharged into the material guiding channel 109 through the discharge port 106, thereby reducing the risk of blockage of the discharge port 106 and improving the efficiency of borax delivery.

It should be pointed out that, for those skilled in the art, several modifications, improvements and substitutions can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
