When the heat treatment shelf slides to the placement area, the limiting block 11 rotates from the limiting groove 9 to the bottom groove 3 to limit the heat treatment shelf placed on the roller 5, thereby avoiding the instability caused by the sliding of the heat treatment shelf when the moving seat 2 drives the heat treatment shelf to move.

[0032] Further, the lifting assembly 8 comprises a lifting table 81 which is opposite to the processing table 1 in the horizontal direction. Threaded rods 82 are screwed at the four corner positions of the lifting table 81, and motors two 83 are connected to the bottom ends of the threaded rods 82.

[0033] Further, the top of the lifting table 81 is provided with a mounting groove 84, and a plurality of movable cylinders 86 are installed in parallel on the inner wall of the mounting groove 84 along the moving direction of the moving seat 2 through a fixing rod 85.

[0035] A plurality of fixing rods 85 are fixedly connected in parallel on the inner wall of the mounting groove 84, and a movable cylinder 86 is sleeved on the side wall of each fixing rod 85 to facilitate the operator to push the heat treatment shelf on the lifting table 81 to the roller 5.

[0036] Further, the moving assembly 7 comprises a lead screw 71 which is rotatably installed at one end on the side wall of the processing box 6 and connected at the other end to the output shaft end of a motor one 72. The side wall of the lead screw 71 is fixedly connected with the side wall of the moving seat 2 through a nut 73.

[0037] Specifically, the motor one 72 controls the rotation of the lead screw 71 to drive the nut 73 to move the moving seat 2 in the horizontal direction to drive the heat treatment shelf to enter and exit the processing box 6.

[0038] Further, a trapezoidal block 14 is arranged on the side of the lifting table 81 away from the processing table 1. A placement groove 15 is formed on the top of the trapezoidal block 14 along the inclined direction, and an auxiliary cylinder 17 is installed on the inner wall of the placement groove 15 along the inclined direction of the top of the trapezoidal block 14 through a mounting rod 16.

[0039] Specific is, the inner wall of the placing groove 15 is fixed with a plurality of installation rods 16 along the inclined direction of the top of the trapezoidal block 14, and the side wall of each installation rod 16 is sleeved with an auxiliary cylinder 17. The trapezoidal block 14 and the auxiliary cylinder 17 are arranged, so that the operator can place the heat treatment rack on the trapezoidal block 14 on the ground and slide to the lifting platform 81 along the auxiliary cylinder 17, facilitating subsequent carrying.

[0040] Further, the top of the processing box 6 is provided with a mounting frame 18, and a motor-driven lifting rod 19 is oppositely mounted on the mounting frame 18. The telescopic end of the motor-driven lifting rod 19 is connected with a closing door 20, and the closing door 20 penetrates the top of the processing box 6 and extends into the processing box 6.

[0041] Further, the bottom of the closing door 20 is provided with an empty area 12 in the bottom groove 3, and the top of the moving seat 2 is provided with an empty groove 13 on both sides of the empty area 12.

[0042] Specifically, the telescopic end of the motor-driven lifting rod 19 controls the closing door 20 to move in the vertical direction to open or close the passage of the processing box 6.

[0043] The empty area 12 and the empty groove 13 are arranged, so that the passage of the processing box 6 can be completely closed by the closing door 20, so that a large gap is not formed between the closing door 20 and the moving seat 2 during the falling process due to the existence of the roller 5, and the efficiency of heat treatment is reduced.

[0044] In addition, the processing table 1 is also provided with a battery and a control button, and the battery supplies power to the driving device (motor and motor-driven lifting rod 19) of the device, and the control button is used to control the driving device of the device to work.

[0045] The working principle and use process of the utility model: after the utility model is installed, the operator places the heat treatment rack with steel materials on the trapezoidal block 14, and slides the heat treatment rack to the lifting platform 81 by means of the auxiliary cylinder 17, and the motor 2 83 controls the corresponding threaded rod 82 to rotate, so that the lifting platform 81 drives the heat treatment rack to move upwards to the position where the moving seat 2 is flush.

[0046] The operator pushes the heat treatment rack from the lifting platform 81 to the moving seat 2 by means of the movable cylinder 86 and the roller 5, and rotates the limiting block 11 from the limiting groove 9 to the bottom groove 3 to limit the heat treatment rack placed on the roller 5, so that the heat treatment rack does not slide and is unstable when the moving seat 2 drives the heat treatment rack to move.

[0047] The motor 72 controls the rotation of the screw rod 71 to drive the nut 73 to move the moving base 2 in the horizontal direction, so as to drive the heat treatment rack into the processing box 6, and the telescopic end of the electric lifting rod 19 controls the downward movement of the closing door 20 to close the passage of the processing box 6, so as to perform the heat treatment operation.

[0048] During the heat treatment, the operator places another heat treatment rack with steel materials on the moving base 2 at the placement area outside the processing box 6 through the above steps, so that when the heat treatment in the processing box 6 is completed and the heat treatment rack is removed from the processing box 6, the other heat treatment rack is simultaneously sent into the processing box 6 for a new round of heat treatment, thereby improving the carburizing heat treatment efficiency of the steel materials.

[0049] The above only describes the preferred embodiments of the present application and is not intended to limit the present application, and any modification, equivalent replacement and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
