In order to facilitate the staff to take the worm gear on the storage plate 203a, when the worm gear is heated, the staff turns the handle 104b, and the handle 104b drives the transmission gear plate 104a to rotate, so that the sealing door 106e rises (when the sealing door 106e is at the bottom, the sealing door 106e drives the first plug rod 303a to move, and then the first plug rod 303a squeezes the follower rod 303b to descend, and at the same time drives the second cross plate 205e to descend, at this time the second cross plate 205e drives the first spring 205d to contract, and the second cross plate 205e drives the block 205f to disengage from the inside of the slot 205a, and restricts the storage plate 203a through the first plug rod 303a and the through-hole 301). The door 106e drives the short rod 106f until it contacts the fixed block 106c. During the rising process of the sealed door 106e, the sealed door 106e drives the first plug rod 303a to be pulled out from the inside of the through-hole 301, so that the first plug rod 303a does not squeeze the follower rod 303b. At this time, the follower rod 303b will move upward under the action of the reverse force of the first spring 205d, and at the same time will drive the second cross plate 205e to rise. As the follower rod 303b rises, the slot 304e will be driven to rise synchronously. When the slot 304e is relative to the second plug rod 304a, the second spring 304d will restore the movement, which can also drive the ring 304b to move. The ring 304b can drive the second plug rod 304a to be inserted into the inside of the slot 304e, and limit the position of the follower rod 303b. At this time, the first spring 205d still cannot be restored.

[0081] Since the storage plate 203a loses the restriction of the block 205f and the first plug rod 303a, the third spring 305e recovers and drives the fixed plate 204b to move together, the fixed plate 204b drives the cross block 204a to move, the cross block 204a drives the storage plate 203a to move, the storage plate 203a drives the worm to extend from the inside of the shell 101, the fixed plate 204b drives the long rod 305d to move, the long rod 305d drives the piston 305f to squeeze the air inside the air pipe 305g, and through the setting of the conical rubber tube 305c, the air in the air pipe 305g is released. When the internal gas flows, the mouth of the conical rubber tube 305c will shrink, reducing the outflow speed of the air pipe 305g, thereby slowing down the recovery speed of the third spring 305e, so that the third spring 305e slowly pushes the fixed plate 204b, the fixed plate 204b drives the cross block 204a, the cross block 204a drives the storage plate 203a, and the storage plate 203a drives the worm to slowly extend out from the inside of the shell 101, so that the staff can take it easily and avoid entering the inside of the shell 101 to take the worm and avoid scalding.

[0082] When the worm is heated for the second time next time, the staff places the worm on the storage plate 203a and pulls the pull ring 304c. The pull ring 304c drives the second plug rod 304a, and the second plug rod 304a drives the circular ring 304b to move. The circular ring 304b drives the second spring 304d to contract, so that the second plug rod 304a is disengaged from the inside of the slot 304e. At this time, the first spring 205d recovers and drives the second cross plate 205e to rise, and the second cross plate 205e drives the block 205f to return to the initial position. When the cross block 204a contacts the shell 101, the block 205f can be reinserted into the inside of the slot 205a.

[0083] Example 4

[0084] Reference Figure 2 This embodiment is different from the above embodiments in that: a heat treatment process for worm manufacturing, the worm is placed flat in a heating furnace, and a step heating method is adopted for the worm. After the worm is heated, a hook is used to vertically lift the worm, and the worm is placed in a cooling pool for cooling. The worm is placed on a lathe for processing and forming, and the processed worm is placed in the heating furnace for secondary heating.

[0085] Furthermore, the worm is kept horizontal relative to the furnace bottom plate, and the bending deformation of the worm is controlled within the subsequent processing allowance range to prevent excessive bending deformation;

[0086] Furthermore, due to being in a high temperature state for a long time, it is very easy to bend and deform during the heating, transfer and cooling process. In order to control the bending deformation of the worm within the subsequent processing allowance range and prevent the worm from being excessively bent and deformed, vertical lifting is adopted during the transfer process. A certain processing allowance is left during the rough turning process of the previous machine tool.

[0087] Furthermore, in order to reduce the temperature difference between the inside and outside, a step heating method is adopted during heating with an additional section of temperature maintained at 630°C in the middle, so as to avoid thermal stress caused by temperature difference when the worm core is in an elastic state, forming cracks in the worm core or expanding the original fiber cracks.

[0088] Furthermore, water-air cooling is adopted, and the worm is cooled by using water and air, two cooling media with the largest difference in cooling capacity, no pollution to the environment and the lowest use cost.

[0089] Hardenability analysis:

[0090] Due to the complex structure and great disparity in thickness of the worm itself, great thermal stress and structural stress will be generated during the heating and cooling process. This stress will cause cracks in the weak parts of the worm structure. Therefore, for the weak parts of the worm, the size is increased before quenching and then processed to the required size after quenching. For the irregularly shaped parts, the ribs are left before quenching and removed after quenching. During the turning process, all sharp-angle structures at the step transitions are designed as rounded transitions.

[0091] Process parameter analysis:

[0092] A reasonable heat treatment process is adopted, including correctly controlling the heating speed, reasonably selecting the quenching heating temperature, and correctly selecting the cooling method and cooling medium. In order to adjust the hardness of the worm, improve the machinability, refine the internal grains and eliminate the network carbides, and prepare the organization for quenching, the worm is first normalized. From the working conditions of the worm, the worm must not only have high strength and hardness, but also have sufficient plasticity and toughness. In order to meet the above working requirements of the worm, it is determined that the worm must be tempered after quenching. It is also the last process of the worm heat treatment. Tempering plays a decisive role in the final performance required by the worm. The main purpose of tempering:

[0093] a. Reduce brittleness and eliminate or reduce internal stress. After quenching, the worm will have great internal stress and brittleness. If it is not tempered in time, the worm will deform or even crack, and it is easy to break during operation.

[0094] b. After quenching, the worm has high hardness and great brittleness. In order to meet the different performance requirements of the worm, tempering is used to adjust the hardness, reduce the brittleness, and make it have a certain toughness and plasticity.

[0095] c. After quenching, the martensite and residual austenite in the steel are unstable structures, which will slowly decompose at room temperature, causing changes in size and shape. Therefore, tempering treatment must be carried out to prevent these changes from occurring during the use of the worm.
