Then, nitrogen is circulated into the vacuum furnace 1 through the air inlet 18 and the air outlet 19 to achieve rapid cooling, effectively improving the annealing efficiency of the electroplated brass wire used in the production of diamond wire.

[0025] It includes a first material rack 3, a second material rack 4 and a first track 5. The first material rack 3 is arranged at the feeding end of the vacuum furnace 1. The first material rack 3 is fixedly arranged on the ground. A first track 5 is arranged between the first material rack 3 and the furnace door 2. A second material rack 4 is slidably arranged on the first track 5. The extending direction of the first track 5 is perpendicular to the axial direction of the vacuum furnace 1. The sliding of the second material rack 4 on the first track 5 can avoid interference with the opening and closing of the furnace door 2 of the vacuum furnace 1. A motor or other devices in the prior art that can drive its movement (not shown in the figure) are arranged on the second material rack 4. A second track 6 is arranged on the first material rack 3.

The inner track of the vacuum furnace 1 is matched with the third track 7, and the third track 7 is matched with the second track 6. The extending directions of the first track 5 and the third track 7 are perpendicular. When the second material rack 4 moves between the first material rack 3 and the vacuum furnace 1 and faces the vacuum furnace 1, both ends of the third track 7 are respectively connected to the second track 6 and the inner track of the vacuum furnace 1.

[0026] A support frame 8 is slidably arranged on the second track 6 for storing materials to be sent into the vacuum furnace 1 for heating, that is, the support frame 8 is used to place the electroplated brass wire wound on the spool. A trolley 9 is also slidably arranged on the second track 6. The trolley 9 moves on the second track 6 and the third track 7 to drive the support frame 8 to move, so as to realize the loading and unloading of the vacuum furnace 1. A clamping mechanism is arranged on one side of the trolley 9 for connecting or disconnecting the support frame 8 and the trolley 9. When the clamping mechanism connects the support frame 8 and the trolley 9, the support frame 8 is driven to move by the movement of the trolley 9, so as to push the support frame 8 and the materials thereon into or out of the vacuum furnace 1. When the clamping mechanism disconnects the support frame 8 and the trolley 9, the trolley 9 moves independently. A power mechanism is arranged on the trolley 9 for driving the trolley 9 to move along the second track 6 and the third track 7. The power mechanism is a motor plus a reducer or other devices in the prior art that can drive a trolley on a track to move.

[0027] Push-pull rods 10 are fixedly arranged at both ends of the support frame 8. The connection or disconnection between the support frame 8 and the trolley 9 is realized by the cooperation of the push-pull rods 10 and the clamping mechanism. The clamping mechanism includes two vertical plates 11 fixedly arranged on one side of the trolley 9. An adjusting rod 12 is rotatably connected between the two vertical plates 11. A driving device is arranged on one of the vertical plates 11 for driving the adjusting rod 12 to rotate. A plurality of claw jaws 13 are fixedly sleeved on the adjusting rod 12. The plurality of claw jaws 13 correspond to one of the push-pull rods 10. The rotation of the adjusting rod 12 drives the claw jaws 13 to rotate, so as to realize the claw jaws 13 hooking or disconnecting from the push-pull rod 10, and further realize the connection or disconnection between the trolley 9 and the support frame 8.

[0028] The driving device includes a first motor 14 fixedly arranged on one of the vertical plates 11.

An arc-shaped side plate is fixedly arranged at one end of the bottom plate away from the mounting block. The arc-shaped inner side of the side plate faces the mounting block. The corresponding push-pull rod 10 passes through the space between the side plate and the mounting block. When the claw jaw 13 rotates to the position where the corresponding push-pull rod 10 passes through the space between the side plate and the mounting block, when the trolley 9 moves on the track, the push-pull rod is driven to move through the side plate and the mounting block, that is, the support frame 8 is driven to move.

[0030] When loading the vacuum furnace 1, first place the electroplated brass wire to be annealed on the support frame 8. The first motor 14 drives the claw 13 to rotate until the corresponding push-pull rod 10 passes through the inside of the claw 13, realizing the connection between the material cart 9 and the support frame 8. Subsequently, open the furnace door 2, and drive the second material rack 4 to move until it is located between the first material rack 3 and the vacuum furnace 1. At this time, both ends of the third track 7 are respectively connected to the second track 6 and the inner track of the vacuum furnace 1. Subsequently, the power device drives the material cart 9 to move towards the vacuum furnace 1. The support frame 8 moves accordingly, and successively passes through the second track 6 and the third track 7 and then moves into the inner track of the vacuum furnace 1. Subsequently, the first motor 14 drives the claw 13 to rotate in the reverse direction, releasing the corresponding push-pull rod 10, and then the material cart 9 disconnects from the support frame 8. Subsequently, the power device drives the material cart 9 to retreat and reset. At this time, drive the second material rack 4 to move away from between the first material rack 3 and the vacuum furnace 1, that is, stagger it from the axial extension direction of the vacuum furnace 1, and close the furnace door 2, then the electroplated brass wire can be annealed.

[0031] When unloading, first open the furnace door 2, and then similarly drive the second material rack 4 to move so that both ends of the third track 7 are respectively connected to the second track 6 and the inner track of the vacuum furnace 1. Subsequently, the power device drives the material cart 9 to move towards the support frame 8 inside the vacuum furnace 1. When the claw 13 is located below the corresponding pull rod 10, the first motor 14 drives the claw 13 to rotate so that the push-pull rod 10 is placed inside the claw 13, and the material cart 9 retreats and resets, pulling the support frame 8 out of the vacuum furnace 1 until the support frame 8 is located on the second track 6. At this time, the annealing treatment of the next batch of electroplated brass wire can be carried out, or move the second material rack 4 away and close the furnace door 2 to complete the unloading of the vacuum furnace 1.
