[0023] The utility model provides a furnace car interchangeable annealing furnace: it comprises a working heating furnace body 101 and a material feeding and discharging mechanism, wherein the material feeding and discharging mechanism comprises a slide rail 105, a first furnace car 106, a second furnace car 107, two support frames 108, two support plates 109, two clamping plates 110, two electric telescopic rods 111, two rotating shafts 115, two motors 116, two clamping parts 117, two cylinders 112, two furnace doors 113 and two insulation frames 118.

[0024] According to a specific implementation scheme, a first inlet and outlet port 102 and a second inlet and outlet port 103 are provided on the heating furnace body 101, and four supporting legs 104 are provided at the bottom of the heating furnace body 101. The heating furnace body 101 is used for heating, and the first furnace car 106 enters the heating furnace body 101 through the first inlet and outlet port 102, and the second furnace car 107 enters the heating furnace body 101 through the second inlet and outlet port 103. The supporting legs 104 are used to support the heating furnace body 101.

[0025] The slide rail 105 is arranged below the first material inlet and outlet 102 and the second material inlet and outlet 103, the first furnace car 106 and the second furnace car 107 are respectively slidably arranged on the slide rail 105, and the first furnace car 106 is located at one end of the first material inlet and outlet 102, and the second furnace car 107 is located at one end of the second material inlet and outlet 103, the two support frames 108 are respectively arranged at both ends of the slide rail 105, the two support plates 109 are respectively arranged above the support frames 108, the two motors 116 are respectively arranged above the two support plates 109, the two rotating shafts 115 are respectively connected between the two motors 116 and the two electric telescopic rods 111, the two clamping plates 110 are respectively fixedly connected to the output ends of the two electric telescopic rods 111, and the two clamping members 117 are respectively connected to the first furnace car 106 and the second furnace car 107 The two clamps 110 are respectively matched with the two clamps 117, and the clamps 117 have a slot. The workpiece is placed in the first furnace car 106, and the electric telescopic rod 111 close to the first furnace car 106 operates to push the clamp 110 connected thereto to move toward the first furnace car 106. At this time, the clamp 110 is in a vertical state. When the clamp 110 contacts the first furnace car 106, the first furnace car 106 is pushed into the heating furnace body 101. When the first furnace car 106 completely enters the heating furnace body 101, the electric telescopic rod 111 contracts to drive the clamp 110 to reset. At this time, the workpiece in the first furnace car 106 is sintered. At the same time, the operator performs preparation work to put the workpiece into the second furnace car 107. When sintering is completed, the electric telescopic rod 111 operates again, pushing the clamping plate 110 to move toward the first furnace car 106 again. When the clamping plate 110 contacts the first furnace car 106, the motor 116 rotates, driving the rotating shaft 115, the electric telescopic rod 111 and the clamping plate 110 to rotate, so that the clamping plate 110 is in a horizontal state. At this time, the clamping plate 110 is stuck in the slot in the clamping member 117, and the electric telescopic rod 111 contracts to drag the first furnace car 106 out of the heating furnace body 101. At the same time, the operator pushes the second furnace car 107 into the heating furnace body 101, sintering the workpiece in the second furnace car 107, repeating the operation, realizing the seamless connection and interchange of the two furnace cars, and ensuring the continuity and efficiency of the production process.

[0026] Among them, the two cylinders 112 are respectively fixedly connected to the heating furnace body 101 and are located on the outer wall of the heating furnace body 101, the two furnace doors 113 are respectively fixedly connected to the output ends of the two cylinders 112 and are located below the cylinders 112, and the two sealing strips 114 are respectively fixedly connected to the two furnace doors 113 and are located on the inner walls of the furnace doors 113. The operation of the cylinder 112 drives the furnace door 113 and the sealing strip 114 to move vertically downward until the furnace door 113 and the sealing strip 114 close the first inlet and outlet 102 or the second inlet and outlet 103 to prevent heat from dissipating.

[0027] Among them, the two insulation frames 118 are respectively mounted on the inner walls of the first furnace car 106 and the second furnace car 107, and the insulation frames 118 are used to insulate the workpieces in the first furnace car 106 or the second furnace car 107 to prevent the first furnace car 106 or the second furnace car 107 from detaching from the heating furnace body 101 and cooling too quickly, thereby deforming the workpieces.

[0028] When using the furnace car interchange annealing furnace of the utility model, the workpiece is placed in the first furnace car 106, and the electric telescopic rod 111 is operated to push the clamping plate 110 to move in the direction of the first furnace car 106. When the clamping plate 110 contacts the first furnace car 106, the first furnace car 106 is pushed into the heating furnace body 101. When the first furnace car 106 completely enters the heating furnace body 101, the electric telescopic rod 111 contracts to drive the clamping plate 110 to reset, and the cylinder 112 is operated to drive the furnace door 113 and the sealing strip 114 to move vertically downward until the furnace door 113 and the sealing strip 114 completely close the first inlet and outlet 102. At this time, the workpiece in the first furnace car 106 is sintered, and the operator performs preparation work and places the workpiece into the second furnace car 107. When sintering is completed, the electric telescopic rod 111 operates here, pushing the clamping plate 110 to move toward the first furnace car 106 again. When the clamping plate 110 contacts the first furnace car 106, the motor 116 rotates, driving the rotating shaft 115, the electric telescopic rod 111 and the clamping plate 110 to rotate, so that the clamping plate 110 is stuck in the clamping groove of the clamping member 117, and the electric telescopic rod 111 contracts to drag the first furnace car 106 out of the heating furnace body 101. At the same time, the operator pushes the second furnace car 107 into the heating furnace body 101, and interchanges and sinters the workpieces in the second furnace car 107, repeating the operation, realizing seamless connection and interchange of the two furnace cars, and ensuring the continuity and efficiency of the production process.
