Description

Technical Field

[0001] This utility model relates to the field of copper strip coil production, specifically a copper strip coil quenching furnace feeding system. Background Technology

[0002] Quenching furnace technology has been widely used in the strengthening processes of materials such as steel and aluminum alloys. However, the feeding devices of existing quenching furnaces are designed according to the characteristics of the workpieces to be quenched. For example, patent CN209010565U discloses a continuous feeding device for a mesh belt quenching furnace. This device is designed for the large weight of iron castings. The device has a transmission mechanism and a buffer mechanism arranged sequentially between the front plate and the rear plate along the transmission direction of the iron castings. The buffer mechanism plays a role in buffering the iron castings. The front support plate and the rear support plate in the device play a role in supporting the annular mesh belt to prevent the iron castings placed on the annular mesh belt from falling or damaging the annular mesh belt due to excessive weight. For example, patent CN211645361U discloses a feeding and unloading system for an aluminum plate quenching furnace, which includes a feeding assembly, a transverse platform, a circulating roller conveyor, a hoisting assembly, a transfer roller conveyor, and an unloading assembly. The transverse platform is used to transport the material frame on the first circulating roller conveyor to the feeding end of the quenching furnace. The second circulating roller conveyor is set at the discharging end of the quenching furnace and is equipped with a spray assembly. The transfer roller conveyor is used to transfer the material frame on the second circulating roller conveyor to the first circulating roller conveyor. The unloading assembly is used to remove the aluminum plate from the material frame at the corresponding station on the second circulating roller conveyor or the transfer roller conveyor. This system is designed for the large area of ​​aluminum plates and can realize the cyclic operation of the system.

[0003] Copper strip coils are typically loaded in a large, disc-shaped form and require adjustment of their orientation after being output from the previous process before being fed into the quenching furnace. After quenching, the copper strip coils need to be quickly transferred to a quenching water tank for solution quenching. However, in existing technologies, the above process is usually completed in multiple different steps, resulting in low furnace loading and transfer efficiency. Furthermore, traditional quenching furnace systems require a certain distance between the furnace body and the quenching water tank, and the transfer of copper strip coils takes time. This leads to a prolonged exposure time of the quenched copper strip coils to air (approximately 30-60 seconds), resulting in a significant temperature drop (up to 50-80°C) and affecting the quenching quality. Utility Model Content

[0004] The purpose of this utility model is to provide a copper strip coil quenching furnace feeding system, which can realize the posture conversion of copper strip coils and the function of rapid entry and exit from the quenching furnace, thereby improving production efficiency.

The picking fork is mounted on the lifting mechanism and is driven to lift by the lifting mechanism.

[0008] The lateral movement mechanism includes a lateral frame, and a lateral motor and a lateral drive wheel driven by the lateral motor are provided on one side of the lateral frame. A lateral driven wheel is provided on the other side of the lateral frame. A lateral guide rail is provided on the ground, and the lateral drive wheel and the lateral driven wheel move along the lateral guide rail on the corresponding side.

[0009] The longitudinal moving mechanism includes a longitudinal frame mounted on the transverse frame, and a longitudinal motor and a longitudinal drive wheel driven by the longitudinal motor are provided at one end of the longitudinal frame. A longitudinal driven wheel is provided at the other end of the longitudinal frame. A longitudinal guide rail is provided on the transverse frame, and the longitudinal drive wheel and the longitudinal driven wheel move along the longitudinal guide rail on the corresponding side.

[0010] The longitudinal motor is a dual-output shaft motor, with the power shafts at both ends connected to the longitudinal transmission shafts on the corresponding sides, and the end of the longitudinal transmission shaft away from the longitudinal motor is connected to the longitudinal drive wheel on the corresponding side.

[0011] The lifting mechanism includes a lifting mounting frame mounted on the longitudinal frame. The upper end of the lifting mounting frame is provided with a lifting motor and a lifting transmission assembly. The upper end of one side of the lifting mounting frame is provided with a first lifting sprocket, and the lower end is provided with a second lifting sprocket.

The rear end of the picking fork is provided with a lifting seat that is slidably connected to the lifting mounting frame, and the lifting seat is fixedly connected to the lifting chain.

[0012] The lifting transmission assembly includes a lifting drive sprocket, a lifting driven sprocket, a lifting transmission shaft, and a lifting transmission chain. The lifting driven sprocket and each of the first lifting sprockets are mounted on the lifting transmission shaft, the lifting drive sprocket is mounted on the power shaft of the lifting motor, and the lifting drive sprocket is connected to the lifting driven sprocket via the lifting transmission chain.

[0013] The flipping device includes a flipping frame and a base. One end of the base is provided with a flipping drive motor, a flipping transmission assembly and a flipping sprocket, and the other end is provided with a support roller. The flipping sprocket is driven to rotate by the flipping drive motor, and the flipping drive motor transmits torque through the flipping transmission assembly.

[0016] The advantages and positive effects of this utility model are as follows:

[0017] 1. This utility model can realize the posture transformation of copper strip coils and the function of rapid entry and exit from the quenching furnace. The copper strip coils are flipped from vertical to horizontal by the flipping frame in the flipping device. The loading car uses a picking fork with three degrees of freedom of movement in the horizontal, vertical and lifting directions to insert into the material tray on the lower side of the copper strip coil to realize the function of picking up material into the furnace and transferring material after quenching. This improves production efficiency and facilitates the connection and cooperation with other processes.

[0018] 2. This utility model places the quenching water tank below the inlet side of the quenching furnace. The copper strip coil that has been quenched can be quickly taken from the quenching furnace by the material handling fork of the loading trolley and immersed in the quenching water tank to complete the solution quenching treatment. This can ensure the quenching quality and avoid the problem in the prior art where the copper strip coil is exposed to the air for a long time due to the long transfer time (extended by about 30 to 60 seconds), which leads to a significant drop in the temperature of the copper strip coil (the temperature drop can reach 50 to 80°C) and affects the quenching quality.

[0019] 3. All devices in this utility model are automatically controlled to complete the corresponding actions, which improves the automation level of copper strip winding in and out of the quenching furnace.

[0020] 4. This utility model takes into account that copper strip coils (especially ultra-thin copper foil) are easily damaged by mechanical collisions. Therefore, it utilizes the contact and cooperation between the picking fork and the material tray to realize the transfer of copper strip coils, thereby further ensuring product quality.

[0042] The working principle of this utility model is as follows:

[0043] The present invention includes the following steps in operation:

[0044] Step 1: As Figure 6 As shown, the copper strip coil 5, together with the lower tray 6, is first vertically hoisted onto the tilting frame 711 of the tilting device 7 by a crane.

[0045] Step Two: As Figure 5 As shown, the copper strip coil 5, together with the lower tray 6, is driven to a horizontal state by the flipping device 7.

[0046] Step 3: The lateral moving mechanism 31 in the loading trolley 3 is activated to drive the picking fork 34 to move to the set position aligned with the flipping frame 711. Then, the picking fork 34 is driven by the lifting mechanism 33 in the loading trolley 3 to adjust its height and align with the tray 6. Then, the picking fork 34 is driven by the longitudinal moving mechanism 32 in the loading trolley 3 to move forward and insert into the tray 6. After insertion, the lifting mechanism 33 drives the picking fork 34, together with the tray 6 and the copper strip coil 5, to rise to the set height so that the tray 6 is disengaged from the flipping frame 711. Then, the longitudinal moving mechanism 32 drives the picking fork 34, together with the tray 6 and the copper strip coil 5, to move backward to the set position. Then, the lateral moving mechanism 31 is activated to drive the picking fork 34, together with the tray 6 and the copper strip coil 5, to move to the set position aligned with the inlet of the quenching furnace 1.

[0047] Step 4: The furnace door 2 of the quenching furnace 1 rises and opens, the longitudinal moving mechanism 32 in the loading car 3 starts and drives the picking fork 34 to send the material tray 6 and copper strip roll 5 into the quenching furnace 1, and then the picking fork 34 exits the quenching furnace 1, and the furnace door 2 of the quenching furnace 1 falls and closes.

[0048] Step 5: Start quenching furnace 1 to perform quenching operation;

[0049] Step Six: After quenching is completed, the furnace door 2 of the quenching furnace 1 is raised and opened. The longitudinal moving mechanism 32 in the loading cart 3 starts to drive the picking fork 34 to move forward into the quenching furnace 1 and insert the material tray 6. Then, the lifting mechanism 33 in the loading cart 3 starts to drive the picking fork 34 to rise together with the material tray 6 and the copper strip coil 5. Then, the longitudinal moving mechanism 32 drives the picking fork 34 to move backward together with the material tray 6 and the copper strip coil 5 away from the quenching furnace 1. The picking fork 34 moves to the set position above the quenching water tank 4 and then stops.

[0050] Step 7: The lifting mechanism 33 in the loading car 3 starts and drives the picking fork 34 to descend together with the material tray 6 and the copper strip coil 5 into the quenching water tank 4 for solution quenching treatment. After the treatment is completed, the loading car 3 drives the picking fork 34 to rise and send the material tray 6 and the copper strip coil 5 to the next process.

[0051] This invention is mainly used for quenching copper strip coils. Considering that the layers of copper strip coils are usually relatively thin (especially ultra-thin copper foil), this invention avoids the problem in the prior art where the copper strip coil is exposed to air for a longer time (approximately 30-60 seconds longer) due to excessively long transfer time, which leads to a significant drop in the temperature of the copper strip coil (temperature drop of up to 50-80℃) and affects the quenching quality. This invention can also be used for quenching other metal workpieces with similar problems, depending on the actual situation.
