Description

Technical Field

[0001] The utility model relates to the technical field of carburizing furnace hangers, and more particularly to a carburizing furnace hanger with a hook. Background Art

[0002] Carburizing furnace is a new type of energy-saving cycle operation heat treatment electric furnace. There are two forms of heat source selection for carburizing furnace. One is fuel combustion heating, including oil and gas, and the other is electric heating. Carburizing furnace has two types: intermittent and continuous. The pit carburizing furnace is cylindrical and requires a sling to drive the workpiece into the carburizing furnace for heat treatment.

[0003] The patent document with publication number CN206033860U in the prior art provides a new type of carburizing furnace sling, which lifts the hook ring by a crane, moves the sling to the top of the carburizing frame, rotates the sling so that the hook opening of the sling faces the ear of the carburizing frame, and lowers the upper plane of the hook below the ear, then rotates the hook by a certain angle and moves upward so that the hook hooks the ear of the carburizing frame to lift the carburizing frame, lifts the hook ring by a crane, moves downward, and lowers the upper plane of the hook below the ear to separate the hook from the ear of the carburizing frame, and then rotates the hook by a certain angle to remove the carburizing frame, which facilitates actual operation and greatly improves production efficiency.

[0004] Although the device has many beneficial effects, the following problems still exist: during the use of the device, the separate hook is not convenient for adapting to plate-shaped workpieces, the scope of application is insufficient, and the use effect is poor; secondly, during the use of the device, the workpiece is not stable enough inside the carburizing furnace, and it is easy to shake during heat treatment, resulting in uneven heating, which needs to be improved. In view of this, we propose a carburizing furnace hanger with a hook. Utility Model Content

[0028] See also Figure 1-5 ,The utility model provides a technical solution:

[0029] A carburizing furnace hanger with a hook comprises a carburizing furnace tank 1, with mounting seats 2 welded on both sides of the top of the circumferential inner wall of the carburizing furnace tank 1, a hanger frame 3 is clamped on the bottom of the inner cavity of the mounting seat 2, and an adjusting component 4 is rotatably connected inside the hanger frame 3, and the adjusting component 4 comprises a rotating shaft 401 rotatably connected to the side wall of the hanger frame 3, a gear 402 is fixed at one end of the circumferential outer wall of the rotating shaft 401, crown gears 403 are meshed on both sides of the circumferential outer wall of the gear 402, screws 404 are fixed on the circumferential inner walls of the two crown gears 403, the circumferential inner walls of the two screws 404 are rotatably connected to a fixed shaft 405 located on the side wall of the inner cavity of the hanger frame 3, the circumferential outer walls of the two screws 404 are threadedly connected to sliders 406, steel wire ropes 407 are fixed at the bottom of the two sliders 406, and a hook 408 is fixed at the other end of the steel wire rope 407, and a clamping component 5 is fixed on the inner wall of the mounting seat 2. The present invention works by hooking the workpiece by hooking 408. When the workpiece is plate-shaped, the rotating shaft 401 drives the gear 402 to rotate, thereby causing the crown gear 403 to drive the screw 404 to rotate, and then the two sliders 406 move outward to drive the two hooks 408 to move to the required positions, so as to adapt to the size of the plate-shaped workpiece. The two ends of the plate-shaped workpiece are hooked with hooks 408 respectively, and the mobile hanger frame 3 enters the interior of the carburizing furnace tank 1 for heat treatment, thereby improving the use effect.

[0030] Specifically, the clamping assembly 5 includes two receiving slots 501 defined on either side of the inner wall of the mounting base 2. Multiple springs 502 are fixed to the sidewalls of the receiving slots 501, and a clamping block 503 is fixed to the other end of the spring 502. A clamping slot 504 is defined on both ends of the sidewalls of the hanger frame 3. When the hanger frame 3 enters the interior of the mounting base 2, the bottom edge of the hanger frame 3 presses the clamping block 503 into the receiving slots 501. The rebound force of the springs 502 then drives the clamping block 503 into the clamping slot 504, thereby ensuring a more stable installation of the hanger frame 3 and facilitating more uniform heating.

[0031] Furthermore, limit blocks 409 are welded to both sidewalls of the slider 406, and limit slots 301 are provided on both sidewalls of the inner cavity of the hanger frame 3. The size of the limit blocks 409 matches the size of the limit slots 301. The limit blocks 409 matching the size of the limit slots 301 facilitate smoother movement of the slider 406.

[0032] It is worth noting that a handle 410 is welded to the other end of the rotating shaft 401, and the two crown gears 403 are arranged in opposite directions. The handle 410 is convenient for the operator to use. The two crown gears 403 are arranged in opposite directions, so that when the gear 402 rotates, the two crown gears 403 rotate in different directions, thereby causing the two sliders 406 to move inward or outward at the same time.

[0033] It is noteworthy that the cross section of the block 503 is trapezoidal, and the size and position of the block 503 match the size and position of the slot 504. The trapezoidal block 503 with the same size and position as the slot 504 makes it easier to move when squeezed by the hanger frame 3.

[0034] In addition, the distance between the two mounting bases 2 matches the length of the hanger frame 3, and the size of the inner cavity of the mounting base 2 matches the size of the hanger frame 3. The mounting base 2 that matches the size of the hanger frame 3 prevents the hanger frame 3 from shaking when heated in the carburizing furnace.

[0035] Furthermore, a lifting lug 6 is welded to the top of the sling frame 3, and the cross section of the lifting lug 6 is a semicircular ring. By means of the semicircular lifting lug 6, it is convenient for a crane to hook the sling frame 3 and carry out lifting transfer.

[0036] Working principle: When this device is needed to be used as a carburizing furnace hanger with a hook, the hook 408 is hooked to the workpiece to work. When the workpiece is plate-shaped, the handle 410 is turned to drive the rotating shaft 401 to rotate, thereby causing the gear 402 to drive the crown gear 403 to rotate, and then the screw 404 drives the two sliders 406 to move at the same time. The two hooks 408 are moved to a position suitable for the width of the plate-shaped workpiece, and the two ends of the plate-shaped workpiece are hooked with hooks 408 respectively, and the hanger frame 3 is moved into the carburizing furnace tank 1. When entering the inner cavity of the mounting seat 2 through the hanger frame 3, the bottom edge of the hanger frame 3 squeezes the block 503 into the accommodating groove 501, and the rebound force of the spring 502 drives the block 503 to move into the groove 504.
