Description

Technical Field

[0001] This utility model relates to the field of metal parts manufacturing, and in particular to a heat treatment device for metal parts manufacturing. Background Technology

[0002] Metal parts processing is one of the steps in industrial production. In the process of metal parts processing, heat treatment is required.

The device includes a housing, a heater fixedly mounted at the bottom of the housing, a heating frame slidably mounted inside the housing, a first rotating rod rotatably mounted at the left end of the housing parallel to the length of the heating frame, and a second rotating rod rotatably mounted at the right end of the housing parallel to the first rotating rod. A first fixed column is coaxially fixed at the middle of the first rotating rod, and first lifting rods are evenly distributed on the outer surface of the first fixed column. A second fixed column is coaxially fixed at the middle of the second rotating rod, and second lifting rods are evenly distributed on the outer surface of the second fixed column. This invention utilizes the reciprocating movement of the heating frame to lift and rotate it at both ends, causing the metal parts inside the heating frame to be dispersed and distributed, increasing the heat treatment effect. The inertia is used to reduce the impact of potential accumulation of metal parts inside the heating frame after rotation.

However, different metal parts require significantly different heating temperatures and holding times due to variations in material, shape, and performance requirements. For example, quenching structural steel may require rapid heating to over 800℃, while aging aluminum alloys require slow heating to a lower temperature and prolonged holding. A single heating system cannot simultaneously meet these diverse needs; therefore, improvements were made to address the aforementioned issues. Utility Model Content

[0027] Reference Figure 1 , Figure 3 , Figure 4A worm gear assembly 514 is fixedly connected to the outer extension end of the transmission rod 414. The worm gear assembly 514 also includes a worm gear body 5141, which is fixedly connected to the outer extension end of the transmission rod 414. The worm gear body 5141 meshes with the worm 513, transmitting power and driving the transmission rod 414 to rotate, thereby causing the fixed mesh frame 415 to flip. The inner wall of the worm gear body 5141 is slidably connected with teeth 5145, which mesh with the worm 513. 13 meshing teeth 5145, the number and length of which are adjustable. By changing the number of teeth 5145, the rotation speed of the worm gear body 5141 can be changed, thereby adjusting the flipping speed of the fixed mesh frame 415. The outer wall of the teeth 5145 has insertion holes 5146 for inserting and removing the rod 5143. The length of the teeth 5145 can be adjusted by the cooperation of the rod 5143 and the insertion hole 5146. The rod 5143 is inserted into the outer wall of the worm gear body 5141. The inner extension of the rod 5143... The extension end is inserted into the inner wall of the insertion hole 5146. The insertion rod 5143 is inserted into the insertion hole 5146 of the tooth 5145 to fix the position of the tooth 5145, ensuring the stability of the meshing transmission between the worm gear body 5141 and the worm 513, and facilitating the adjustment of the length of the tooth 5145. A connecting plate 5142 is fixedly connected to the outer wall of the insertion rod 5143. The connecting plate 5142 is detachably connected to the worm gear body 5141 by bolt B5144 and is used to fix the insertion rod 5143 and adjust the length of the tooth 5145. To provide convenience, the connecting plate 5142 is detachably connected to the outer wall of the worm gear body 5141 by bolt B5144.

[0028] Working principle: Four heating boxes 2 are installed on the top of the base 1. By pulling the locking block 613, the fixed mesh frame 415 connected by the wire rope 611 is raised. Then, the cover plate 417 of the fixed mesh frame 415 is opened and metal parts of different specifications are placed inside. The cover plate 417 is fastened by bolt A416. The heating ring 7 at the bottom of the heating box 2 heats the metal parts. The motor 512 drives the worm 513 at the output end to rotate. When the worm 513 rotates, it drives the meshing worm wheel assembly 514 to rotate. When the worm wheel body 5141 rotates, it drives the transmission rod 414 to rotate. When the transmission rod 414 rotates, it drives the fixed mesh frame 415 connected to the outer wall of the transmission rod 414 to rotate, thereby fully and evenly heating the metal parts placed inside the fixed mesh frame 415.

[0029] Meanwhile, the connecting plate 5142 is detachably connected to the worm gear body 5141. Therefore, when the insert rod 5143 on the outer wall of the connecting plate 5142 is disengaged from the insertion hole 5146 on the outer wall of the tooth 5145, the length of the tooth 5145 can be adjusted individually. Then, the length of the tooth 5145 is adjusted by inserting the insert rod 5143 into the insertion hole 5146 in the tooth 5145 (from the original 12 teeth 5145 to 6 teeth 5145). After the number of teeth 5145 is adjusted, the connecting plate 5142 is fixed by bolt B5144. The entire assembly can adjust the rotation speed of each worm gear assembly 514 according to the required rotation speed in the fixed mesh frame 415 in each heating box 2. When the number of teeth 5145 on the worm gear body 5141 decreases, the rotation speed of the mesh frame slows down (the entire assembly can be adjusted according to the material and shape of the metal parts in the fixed mesh frame 415).
