The bottom of the collection box has a support leg, and the support leg abuts against the ground.

[0007] The outer surface of the collection box is connected to a dark-colored baffle by bolts, and the dark-colored baffle is set in an arc-shaped structure.

[0008] By adopting the above technical solution, the automatic conveying and rotary heating of alloy bars are achieved through the coordinated design of the feeding mechanism, transmission mechanism and annealing mechanism; the heating coil combined with the blower directionally removes the oxide scale, the collection box concentrates the debris through the wedge-shaped slag guide surface, the dark baffle isolates splashes and allows observation, and the support legs enhance the collection stability.

[0009] Furthermore, the collection mechanism is used to collect oxide debris, and the blower ensures that the oxide debris falls off quickly.

[0011] Furthermore, the dark baffle facilitates workers' observation of the annealing process of the alloy rod. The dark baffle is a high-temperature ceramic ink glass cover plate, and a control panel is provided on one side of the heating coil base.

[0012] By adopting the above technical solution, the black baffle is made of high-temperature ceramic ink glass, which allows light to pass through and observe the annealing process while blocking the spread of debris; the control panel integrates an operation interface to simplify the process.

[0013] Furthermore, the feeding mechanism includes a base, a track is provided on the top of the base, a linear motor is provided inside the base, a transmission seat is provided inside the track, and the transmission seat is detachably connected to the moving end of the linear motor.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] In this embodiment:

[0032] An annealing heat treatment apparatus for alloy bars, such as Figure 1-4 As shown, it includes a feeding mechanism 1, a transmission mechanism 2, and an annealing mechanism 3. The annealing mechanism 3 includes a heating coil seat 301. A heating coil 303 is provided below the outer surface of the heating coil seat 301. A blower 305 is provided above the heating coil 303 via a mounting rod 304.

[0033] A collection mechanism 4 is provided directly below the blower 305. The collection mechanism 4 includes a collection box 401. The top of the collection box 401 is provided with a box groove, and the inner wall of the box groove is provided with a wedge-shaped guide surface 402. The bottom of the collection box 401 is provided with a support leg 403, and the support leg 403 abuts against the ground.

[0034] The outer surface of the collection box 401 is detachably connected to a dark baffle 404 by bolts. The dark baffle 404 has an arc-shaped structure. The feeding mechanism 1 achieves precise positioning and conveying of the bar 5 through the track 102 of the base 101 and the transmission seat 103. The heating coil 303 of the annealing mechanism 3 induction heats the bar 5 below the heating coil seat 301. At the same time, the blower 305 fixed by the mounting rod 304 accelerates the removal of oxide scale through directional airflow. The debris slides into the collection box 401 through the slag guide surface 402 for temporary storage. The dark baffle 404 is detachably connected by bolts. Its arc-shaped structure fits the outer contour of the bar 5, blocking debris splashing while providing a viewing window. The support leg 403 contacts the ground to ensure the stability of the collection box 401 and avoid vibration and displacement.

[0035] See Figure 3 , Figure 4 The collecting mechanism 4 is used to collect oxide debris, and the blower 305 ensures that the oxide debris falls quickly. The blower 305 is set directly in front of the heating coil 303, and the airflow covers the heated area on the surface of the bar 5, accelerating the peeling of the oxide scale. The debris falls to the slag guiding surface 402 of the collecting box 401, and its wedge-shaped structure guides the debris to gather at the bottom of the box to avoid accumulation and blockage. The collecting box 401 and the support leg 403 cooperate to form a semi-enclosed space to prevent debris from overflowing and polluting the working environment.

[0036] See Figure 1 , Figure 2The dark baffle 404 facilitates workers' observation of the annealing of the alloy rods. The dark baffle is a high-temperature ceramic ink glass cover. A control panel 302 is set on one side of the heating coil base 301. The arc-shaped structure of the dark baffle 404 is connected to the outer wall of the collection box 401 by bolts. The high-temperature ceramic ink glass is resistant to annealing temperature, and its dark color and light transmission characteristics facilitate observation of the heating color of the rods 5. The control panel 302 is located on the side of the heating coil base 301 and integrates heating parameter adjustment and feeding speed control functions to improve the ease of operation.

[0037] See Figure 1 , Figure 4 The feeding mechanism 1 includes a base 101, a track 102 on the top of the base 101, a linear motor inside the base 101, and a transmission seat 103 inside the track 102. The transmission seat 103 is detachably connected to the moving end of the linear motor. The track 102 of the base 101 cooperates with the linear motor, and the transmission seat 103 is fixed to the moving end of the motor through a detachable connector. After the bar 5 is initially positioned by the support frame 105, the transmission seat 103 pushes it horizontally along the track 102 to the annealing station to avoid positioning deviation caused by manual handling.

[0038] See Figure 3 , Figure 4 A pneumatic clamp 104 is provided on the transmission seat 103, and the pneumatic clamp 104 is used to clamp the alloy bar 5. The pneumatic clamp 104 on the transmission seat 103 drives the jaws to close by air pressure, and the clamping force is evenly distributed to prevent indentation on the end face of the bar 5. After clamping, it moves along the track 102 with the transmission seat 103. After annealing, it automatically releases, reducing manual intervention.

[0039] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The back of the base 101 is provided with a transmission mechanism 2, which includes a lifting linear motor 201. The moving end of the lifting linear motor 201 is detachably connected to the mounting base 202 via a mounting bracket. The lifting linear motor 201 drives the mounting base 202 to move vertically. The mounting bracket and the moving end are detachably connected to ensure that the contact pressure between the transmission wheel 203 and the surface of the bar 5 is adjustable to adapt to the clamping and rotation requirements of bars of different specifications.

[0040] See Figure 1 The mounting base 202 is equipped with two motors, and the output ends of the two motors are respectively equipped with two transmission wheels 203. The two transmission wheels 203 are used to clamp the alloy rod and cause the alloy rod 5 to rotate. The two motors inside the mounting base 202 drive the two transmission wheels 203 respectively. The rod 5 is clamped and rotated synchronously through the V-shaped centering structure, eliminating slippage or uneven speed caused by single-point drive and improving the consistency of annealed layer thickness.

[0041] See Figure 1 , Figure 4 A tube support frame 105 is provided on the top of the base 101 near the annealing mechanism 3. Two driven rollers on the top of the tube support frame 105 are used to support and ensure the stability and rotation of the alloy bar 5. The tube support frame 105 is located on the side of the base 101 near the annealing mechanism 3. The two driven rollers on its top rotate freely. When the bar 5 is conveyed, it is supported by the rollers, which reduces the sliding friction with the tube support frame 105 and avoids surface scratches.

[0042] The implementation principle of this embodiment is as follows: First, the operator starts the equipment through the control panel 302 and places the alloy bar 5 to be processed on the support frame 105 of the feeding mechanism 1. The two driven wheels at the top of the support frame 105 adaptively fit the outer wall of the bar to form a stable support. Then, the pneumatic clamp 104 of the feeding mechanism 1 moves along the track 102 to the end of the bar under the drive of the linear motor. After clamping and fixing, the bar is horizontally transported to the heating station center of the annealing mechanism 3 through the transmission seat 103.

[0043] When the bar 5 reaches the annealing position, the lifting linear motor 201 of the transmission mechanism 2 drives the mounting base 202 to descend, so that the two transmission wheels 203 contact the surface of the bar. The motor drives the transmission wheels 203 to drive the bar to rotate at a constant speed. The heating coil 303 of the annealing mechanism 3 starts synchronously and heats the rotating bar 5 evenly through the principle of electromagnetic induction. Under the action of high temperature, the surface oxide layer expands and peels off.

[0044] The blower 305 is fixed directly above the heating coil 303 by the mounting rod 304, and its air outlet is aimed at the surface of the rod 5. The directional airflow accelerates the removal of oxide scale and debris. The debris falls naturally under the action of gravity and is guided into the box by the wedge-shaped slag guide surface 402 on the top of the collection box 401 for centralized temporary storage to avoid scattering and pollution. The dark baffle 404 on the outside of the collection box 401 is detachably connected by bolts. Its arc structure surrounds the outer perimeter of the rod 5, blocking debris from splashing while allowing the operator to observe the color change of the annealing area through the high-temperature ceramic ink glass.

[0045] After annealing, the transmission mechanism 2 lifts the transmission wheel 203 to detach from the bar 5, and the feeding mechanism 1 moves the processed bar out of the work station, completing a single operation cycle. All mechanisms work together through the control panel 302 to achieve synchronous control of oxide scale removal, debris collection and annealing processes.
