Description

Technical Field

[0001] This utility model relates to the field of ductile iron casting production, specifically a heat treatment device for ductile iron castings. Background Technology

[0002] Ductile iron is a high-strength cast iron material with comprehensive properties close to those of steel. Based on its excellent properties, it has been successfully used to cast parts subject to complex stresses and requiring high strength, toughness, and wear resistance. Ductile castings are used in almost all major industrial sectors that demand high strength, plasticity, toughness, wear resistance, resistance to severe thermal and mechanical shocks, resistance to high or low temperatures, corrosion resistance, and dimensional stability.

[0003] Current heat treatment equipment for ductile iron castings, as described in patent CN220364556U, includes a base, a heating furnace fixed to one side of the upper surface of the base, a flame valve installed at the lower end of the inner cavity of the heating furnace, a bracket fixed in the middle of the inner cavity of the heating furnace, a clean air chamber fixed to the upper surface of the heating furnace, and an air pump installed on the upper surface of the clean air chamber; two guide rails fixed to the upper surface of the base, sliding sleeves sleeved on the surface of the guide rails, a movable seat fixed between the upper surfaces of the two sliding sleeves, a cylinder fixed to the upper surface of the movable seat, a lifting seat fixed to the telescopic end above the cylinder, a material transfer frame fixed to one side of the lifting seat, and a lead screw rotatably mounted on the upper surface of the base.

[0004] Regarding the aforementioned technologies, the inventors believe that supporting castings with a set of transfer racks results in a situation where a batch of castings needs to be heat-treated and removed from the heating furnace before the next batch of castings to be heat-treated can be placed on the transfer racks, thus leading to relatively low heat treatment efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a heat treatment device for ductile iron castings to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A heat treatment apparatus for ductile iron castings, comprising:

[0008] The moving mechanism includes a heating furnace. A fixed plate is fixedly connected to the bottom of the heating furnace. Adjusting screws are symmetrically rotatably connected inside the fixed plate. One end of each of the two sets of adjusting screws is rotatably connected to a bracket. A moving seat is threadedly connected to the outer side of each of the two sets of adjusting screws. A worm gear is fixedly connected to the end of each of the two sets of adjusting screws away from the bracket. A worm is meshed with the bottom of each of the two sets of worm gears. A first stepper motor is fixedly connected to one side of the heating furnace. The output end of the first stepper motor is fixedly connected to the worm.

[0009] The rotating mechanism includes a rotating shaft rotatably connected to the interior of the movable seat. A second stepper motor is fixedly connected to the bottom of the movable seat. The output end of the second stepper motor is fixedly connected to the rotating shaft. A rotating seat adapted to the heating furnace is fixedly connected to the top of the rotating shaft. Material holding frames corresponding to the interior of the heating furnace are fixedly connected to both sides of the rotating seat.

[0010] As a further embodiment of this utility model: a support ring is fixedly connected to the top of the movable seat, and balls corresponding to the support ring are symmetrically and movably connected to the bottom of the rotating seat.

[0011] As a further embodiment of this utility model: the bottom of the movable seat is symmetrically and fixedly connected with a first support column, the bottom of the support ring is symmetrically and fixedly connected with a second support column, the second support column is disposed between the adjusting screws, and the bottom of both sets of the first support columns and both sets of the second support columns are fixedly connected with casters.

[0012] As a further embodiment of this utility model: the top of each of the two sets of material holding frames is symmetrically and fixedly connected with a diagonal tie rod, and the end of each set of diagonal tie rods away from the material holding frame is fixedly connected to the rotating seat.

[0013] As a further embodiment of this utility model: a guide seat is rotatably connected at the fixed middle position of the rotating seat, and a guide rod slides symmetrically through the inside of the guide seat. The two ends of the guide rod are respectively fixedly connected to a side plate and the fixing frame, and the side plate is fixedly connected to the top of the heating furnace.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] With the above-described structure, this invention, through the cooperation of the second stepper motor, rotating shaft, rotating seat, and material holding frame, enables the rotating shaft and rotating seat to rotate when the second stepper motor starts working. When the rotating seat rotates, it drives the two sets of material holding frames to rotate as well, allowing the two sets of material holding frames to rotate alternately to the side facing the heating furnace. This allows the workers to remove the heat-treated castings from the other set of material holding frames while the castings in one set of material holding frames are being moved into the heating furnace for heat treatment, and then place the castings to be heat-treated later into the other set of material holding frames. This effectively reduces waiting time and improves the efficiency of heat treatment of castings. Attached Figure Description

[0022] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0023] Please see Figure 1-4A heat treatment apparatus for ductile iron castings includes a moving mechanism 1, which includes a heating furnace 101. The heating furnace 101 is configured to heat the castings during startup. A fixed plate 104 is fixedly connected to the bottom of the heating furnace 101. Adjusting screws 102 are symmetrically rotatably connected inside the fixed plate 104. One end of each of the two sets of adjusting screws 102 is rotatably connected to a bracket 103. The fixed plate 104 and the bracket 103 provide support for the adjusting screws 102. A movable seat 105 is threadedly connected to the outer side of the two sets of adjusting screws 102. Rotation of the adjusting screws 102 can drive the movable seat 105 to move, thereby adjusting the position of the movable seat 105.

[0024] Both sets of adjusting screws 102 have worm gears 107 fixedly connected to their ends away from the bracket 103. The bottoms of the two sets of worm gears 107 are meshed with worms 108. Rotation of the worm 108 drives the two sets of worm gears 107 to rotate synchronously, thereby causing the two sets of adjusting screws 102 to rotate synchronously as well. A first stepper motor 109 is fixedly connected to one side of the heating furnace 101. The output end of the first stepper motor 109 is fixedly connected to the worm 108, allowing the first stepper motor 109 to rotate during startup.

[0025] The rotating mechanism 2 includes a rotating shaft 202 rotatably connected to the interior of the movable base 105. A second stepper motor 201 is fixedly connected to the bottom of the movable base 105, and the output end of the second stepper motor 201 is fixedly connected to the rotating shaft 202. The second stepper motor 201 is configured to drive the rotating shaft 202 to rotate during startup. A rotating seat 203 adapted to the heating furnace 101 is fixedly connected to the top of the rotating shaft 202. The rotating seat 203 can rotate synchronously with the rotating shaft 202. A guide seat 211 is rotatably connected to the intermediate position of the rotating seat 203. A guide rod 210 slides symmetrically through the interior of the guide seat 211, and the movement of the rotating seat 203 is further guided by the guide rod 210 and the guide seat 211.

[0026] The guide rod 210 has a side plate 209 and a fixing frame 208 fixedly connected to its two ends, respectively. The side plate 209 is fixedly connected to the top of the heating furnace 101, and the side plate 209 and fixing frame 208 provide support for the guide rod 210. The top of the movable seat 105 is fixedly connected to a support ring 204, and the bottom of the rotating seat 203 is symmetrically and movably connected to ball bearings 205 corresponding to the support ring 204. The support ring 204 and ball bearings 205 provide auxiliary support for the rotating seat 203, and the ball bearings 205 can roll on the top of the support ring 204 when the rotating seat 203 rotates. The bottom of the movable seat 105 is symmetrically fixedly connected to a first support column 106, which provides auxiliary support for the movable seat 105.

[0027] A second support column 212 is symmetrically fixedly connected to the bottom of the support ring 204. The second support column 212 is positioned between the adjusting screws 102. A caster wheel 213 is fixedly connected to the bottom of both sets of first support columns 106 and both sets of second support columns 212. The second support columns 212 and caster wheels 213 further support the support ring 204, thereby improving its stability. A material holding frame 206, corresponding to the interior of the heating furnace 101, is fixedly connected to both sides of the rotating seat 203. The material holding frame 206 is used to hold the castings to be heat-treated. A diagonal tie rod 207 is symmetrically fixedly connected to the top of both sets of material holding frames 206. The end of each diagonal tie rod 207 away from the material holding frame 206 is fixedly connected to the rotating seat 203. The diagonal tie rod 207 further connects and fixes the rotating seat 203 to the material holding frame 206, thereby improving the connection stability between the rotating seat 203 and the material holding frame 206.

[0028] In this embodiment, the heating furnace 101 is existing technology and will not be described in detail here.

[0029] In use, the casting to be heat-treated is placed inside the material holding frame 206 on one side. Then, the second stepper motor 201 is started, so that when the second stepper motor 201 starts working, it can drive the rotating shaft 202 and the rotating seat 203 to rotate. When the rotating seat 203 rotates, it can drive the two sets of material holding frames 206 to rotate accordingly, until the material holding frame 206 containing the casting to be heat-treated is adjusted to the side corresponding to the heating furnace 101. Then, the first stepper motor 109 is started, so that when the first stepper motor 109 starts working, it can be driven by the worm gear 10 8 drives two sets of worm gears 107 and two sets of adjusting screws 102 to rotate synchronously. When the adjusting screws 102 rotate, they can drive the moving seat 105 and the rotating seat 203 to one side of the heating furnace 101. At the same time, the material holding frame 206 also moves to one side of the heating furnace 101 until the rotating seat 203 moves to abut against the heating furnace 101. Simultaneously, the material holding frame 206 containing the casting to be processed and the casting to be processed move into the interior of the heating furnace 101. Then, the heating furnace 101 can be started to heat the castings contained in the material holding frame 206 on one side. During the processing, the worker can place the next batch of castings to be processed into the other side of the material holding frame 206. After the castings inside the material holding frame 206 on one side have undergone heat treatment, the first stepper motor 109 can be started. The first stepper motor 109 drives the two sets of adjusting screws 102 to rotate synchronously in opposite directions through the transmission of the worm gear 108 and the worm wheel 107. This causes the moving seat 105, the rotating seat 203, and the material holding frame 206 to move away from the heating furnace 101 until the material holding frame 206 is moved out of the heating furnace 101. Then, the second stepper motor 201 is started, which drives the rotating seat 203 to rotate half a turn, so that the other side of the material holding frame 206 rotates with the rotating seat 203 to the side facing the heating furnace 101. Then, the first stepper motor 109 is started again to move the other side of the material holding frame 206 into the interior of the heating furnace 101 to heat treat the castings inside the other side of the material holding frame 206. At this time, the worker can remove the heat-treated castings inside the material holding frame 206 and put in the subsequent castings to be heat-treated, so as to facilitate the subsequent heat treatment of the castings.

They are not intended to limit the present utility model in any way.
