Description

Technical Field

[0001] The present invention relates to the technical field of mechanical equipment, and particularly relates to an inlet and outlet device for a flat vacuum furnace. Background Art

[0002] A vacuum furnace is a device that uses a vacuum system within a specific space of the furnace cavity to evacuate some substances within the furnace cavity, so that the pressure within the furnace cavity is less than one standard atmospheric pressure, and the space within the furnace cavity thus achieves a vacuum state. It is connected to a high vacuum pump system by a pipeline in a furnace chamber sealed by a metal housing or quartz glass cover. The vacuum degree of the furnace chamber can reach 133×(10-2~10-4) Pa. The heating system inside the furnace can be directly heated by an electric resistance furnace wire or by high-frequency induction heating, and the maximum temperature can reach about 3000°C. It is mainly used for ceramic firing, vacuum smelting, degassing of electro-vacuum parts, annealing, brazing of metal parts, and ceramic-metal sealing, etc. When using a flat vacuum furnace, auxiliary tools are required to perform the steps of loading and unloading the material shelf to avoid contact between personnel and the material shelf. An oil cooler is a device that accelerates the heat dissipation of lubricating oil to keep it at a lower temperature. On high-performance and high-power strengthened engines, due to high thermal loads, an oil cooler must be installed. A vacuum furnace is required for the forming and casting process during the preparation of the oil cooling device.

[0003] Currently, there is only one inlet and outlet mechanism for the flat vacuum furnace inlet and outlet device, resulting in low work efficiency. In the vacuum brazing furnace for the oil cooler product, the brazing step is carried out. First, the product taken out of the furnace is pulled out and placed in the cooling area, and then this device is used to send the un-welded product into the furnace. Because there is a certain distance from the furnace outlet to the product unloading area, it will result in a long time and slow efficiency.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an inlet and outlet device for a flat vacuum furnace is provided in order to achieve a more practical purpose. Summary of the Invention

[0006] Further, the directional slideway is slidably connected to the directional slider. The bottom position of the directional slider is fixedly connected to the middle position of the top of the sealing plate, and the sealing plate is located at the rear end of the vacuum furnace body.

[0007] Further, a motor A is arranged at the front end position of the conveyor belt A, and a motor B is arranged at the front end position of the conveyor belt B.

[0008] Further, a control motor is fixedly connected to the front end position of the control frame. The left rotating shaft of the control motor is fixedly connected to the right side position of the special-shaped part A. The special-shaped part A is designed in a U shape and is rotatably connected to the inner right front end position of the control frame. The left side position of the special-shaped part A is fixedly connected to the limit frame.

[0009] Further, a limit bolt is rotatably connected to the middle position on the left side of the limit frame. The limit bolt is inserted into the right side position of the special-shaped part B. The special-shaped part B is designed in a U shape and is designed in the opposite direction to the special-shaped part A. The left side position of the special-shaped part B is rotatably connected to the inner left front end position of the control frame.

[0010] Further, the middle position of the special-shaped part A is rotatably connected to the front end position of the transmission rod A. The transmission rod A is located at the inner right side position of the control frame. The rear end position of the transmission rod A is rotatably connected to the front end position of the reciprocating arm A.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] Place the shelf A above the conveyor belt A, and then place the shelf B above the conveyor belt B. Next, start the control motor. The rotating shaft of the control motor will drive the special-shaped part A to rotate 180 degrees. At this time, the middle convex position of the special-shaped part A is located at the rear position.

At this time, through the cooperation of the transmission rod B and the carriage B, the reciprocating arm B slides forward in the carriage B, and the reciprocating arm B will be located on the right side of the conveyor belt A. Next, start the motor A to make the conveyor belt A in the transportation state. The conveyor belt A moves the shelf A at the upper end to the right position until the shelf A is conveyed to the upper end of the reversing frame B. Next, start the control motor to make its rotating shaft rotate 180 degrees again, so that the middle convex position of the special-shaped part B will be located at the rear position. Through the cooperation of the transmission rod B and the carriage B, the reciprocating arm B slides backward in the carriage B until the reciprocating arm B enters the left side position inside the furnace tank of the vacuum furnace body. The shelf A will enter the left side of the furnace tank of the vacuum furnace body for the brazing step.

[0015] After the brazing step of the materials inside the shelf A, start the motor B. The conveyor belt B will drive the shelf B to move to the left position until the shelf B moves above the reversing frame A. Next, start the control motor again to make its rotating shaft rotate 180 degrees. At this time, the middle convex position of the special-shaped part B will be located at the front position, and the middle convex position of the special-shaped part A is located at the rear position. Through this step, the shelf A and the shelf B will alternately enter the inside of the furnace tank of the vacuum furnace body. Because the entry and exit time is short, the furnace temperature drops less, and the newly welded products can quickly heat up when entering the furnace, shortening the brazing time of the products and improving the work efficiency.

[0016] When the shelf A is in the out-of-furnace state and the reciprocating arm B is flush with the conveyor belt A, next start the cylinder B. The cylinder B will push the shelf A at the upper end of the reciprocating arm B to the upper end position of the conveyor belt A. The conveyor belt A will drive the shelf A to move to the left position to unload and replace the shelf A in time. After the materials of the shelf B are brazed, repeat the previous steps. Through the above steps, the replacement time of the shelf A and the shelf B can be reasonably utilized to avoid wasting time. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] During use: First, assemble the overall combination of this device relatively. Next, place the shelf A5 above the conveyor belt A2, and then place the shelf B6 above the conveyor belt B3. Next, start the control motor 401. The rotating shaft of the control motor 401 will drive the special-shaped part A404 to rotate 180 degrees.
