[0039] like Figures 1-6 As shown, it illustrates a water-cooled, strengthened bolt heat treatment furnace according to an embodiment of the present disclosure, comprising:
[0040] Platform 1 and outer shell 2, with outer shell 2 mounted on platform 1;
[0041] Several heating tubes 3 and feeding / discharging components 5 are provided. The heating tubes 3 are installed between the platform 1 and the outer shell 2. The feeding / discharging components 5 are set on the platform 1.
[0042] Switch assembly 7 is disposed outside the housing 2;
[0043] The receiving box 4 and the water-cooled discharge assembly 6 are provided. The receiving box 4 is located on the side surface of the platform 1, and the water-cooled discharge assembly 6 is located in the receiving box 4.
[0044] The feeding / discharging assembly 5 includes a transmission groove 5-1, which is formed on the surface of the platform 1. A pair of slide rails 5-2 are provided in the transmission groove 5-1. A drive screw 5-3 is installed in the transmission groove 5-1. A pair of movable seats 5-4 are connected to the drive screw 5-3 and the slide rails 5-2. A material rack 5-5 is rotatably connected to one of the movable seats 5-4 via a pin. Several material racks 5-5 are provided and are fixedly connected to each other. A baffle 5-6 is rotatably connected to one side of the material rack 5-5 via a pin. Mesh holes 5-7 are opened on the side surfaces of both the baffle 5-6 and the material rack 5-5. A telescopic cylinder 5-8 is installed on the other movable seat 5-4. A bracket 5-9 is connected to the output end of the telescopic cylinder 5-8. A pair of sleeves 5-10 are provided at the bottom of one of the material racks 5-5. Both ends of the bracket 5-9 are movably embedded in the sleeves 5-10.
[0045] In some examples, during the heat treatment process of bolts, a feeding / discharging assembly 5 is designed to ensure precise feeding and smooth discharge of bolts into the heat treatment furnace. This assembly includes a transmission groove 5-1 formed on the surface of a platform 1. A pair of slide rails 5-2 are installed within the transmission groove 5-1 to support the smooth sliding of the moving seats 5-4. A drive screw 5-3 is installed within the transmission groove 5-1 and its rotation is controlled by a motor. The pair of moving seats 5-4 are connected to the drive screw 5-3 and the slide rails 5-2 respectively. When the drive screw 5-3 rotates, the moving seats 5-4 can move precisely in a straight line along the slide rails 5-2 within the transmission groove 5-1. A material rack 5-5 is rotatably connected to one of the moving seats 5-4 via a pin, and multiple material racks 5-5 are fixedly connected to each other to form a bolt storage system. The container and the material rack 5-5 are also connected to a baffle 5-6 by a pin on one side. The side where the baffle 5-6 is located is the discharge point. Both the material rack 5-5 and the baffle 5-6 have mesh holes 5-7 on their surfaces. These mesh holes 5-7 help with heat transfer. The telescopic cylinder 5-8 installed on another moving seat 5-4 has its output end connected to the bracket 5-9. A pair of sleeves 5-10 are set at the bottom of one of the material racks 5-5. The two ends of the bracket 5-9 can be movably embedded in the sleeves 5-10 to form a transmission structure. When the bracket 5-9 is raised, it will push the material rack 5-5 upward, causing the material rack 5-5 to tilt. At the same time, the bracket 5-9 will slide in the sleeves 5-10. With the change of angle of the material rack 5-5, the bolt will knock open the baffle 5-6 through the tilt angle and roll down.
[0046] like Figures 1-6 As shown, this embodiment proposes a water-cooled discharge assembly 6 including an outer pipe 6-1, which is disposed on the outer surface of the receiving box 4. A spiral auger 6-2 is rotatably connected between the receiving box 4 and the outer pipe 6-1. A separation hole 6-3 is opened at the bottom of the outer pipe 6-1. A bottom cover 6-4 is provided at the bottom of the outer pipe 6-1. A drain pipe 6-5 is provided at the lower end of the bottom cover 6-4. A water pump 6-6 is provided on the outer surface of the receiving box 4. The output end of the water pump 6-6 is connected to the inside of the receiving box 4. A second cylinder 6-7 is provided on the outside of the receiving box 4. A sealing cover 6-8 is provided at the output end of the second cylinder 6-7.
[0047] In some examples, in the subsequent processing after bolt heat treatment, a water-cooled discharge assembly 6 is designed to effectively reduce the bolt temperature. This assembly includes an outer pipe 6-1 located on the outer surface of a receiving box 4, connected to the receiving box 4. A spiral auger 6-2, rotatably connected to the outer pipe 6-1 inside the receiving box 4, can be pushed outwards after the bolt has cooled. A separation hole 6-3 at the bottom of the outer pipe 6-1 separates the cooling water from the bolt. During the cooling process, water flows with the movement of the bolt to the bottom of the outer pipe 6-1 and flows downwards through the separation hole 6-3. The bottom cover 6-4 is used to collect water flowing out of the separation hole 6-3. The drain pipe 6-5 at the lower end of the bottom cover 6-4 discharges the collected water for subsequent treatment or recycling. The water pump 6-6 on the outer surface of the receiving box 4 has its output end connected to the inside of the receiving box 4. The function of the water pump 6-6 is to draw external cooling water into the receiving box 4 to cool the heat-treated bolts that have just entered the receiving box 4. The second cylinder 6-7 on the outside of the receiving box 4 has a sealing cover 6-8 at its output end. When the receiving box 4 discharges material, the sealing cover 6-8 opens and the bolts are discharged outside.
[0048] like Figures 1-6 As shown, this embodiment proposes a switch assembly 7 including a pair of guide rods 7-1, both of which are fixed to the side surface of the housing 2. Door panels 7-2 are slidably mounted on both guide rods 7-1, and the door panels 7-2 are fixedly connected to each other. A third cylinder 7-3 is provided on one side of the housing 2, and the output end of the third cylinder 7-3 is connected to the door panel 7-2.
[0049] In some examples, a switch assembly 7 is designed to achieve a sealing effect during the heat treatment process. This assembly includes a pair of guide rods 7-1 fixed on one side of the housing 2 and a third cylinder 7-3 on the other side. Door panels 7-2 are slidably connected to both guide rods 7-1. The door panels 7-2 can move vertically up and down on the guide rods 7-1. The two door panels 7-2 are fixedly connected to each other and connected to the output end of the third cylinder 7-3. The lifting and lowering of the door panels 7-2 can be controlled by the third cylinder 7-3.
[0050] For example, such as Figure 4 As shown, the inner surface of the receiving box 4 is an inclined structural surface.
[0051] In some examples, the inclined structural surface facilitates the rolling of bolts into the auger 6-2.
[0052] For example, such as Figure 4 As shown, a sealing plate 8 is provided on the side surface of one of the movable seats 5-4, and the sealing plate 8 is located on the same surface as the platform 1.
[0053] In some examples, a sealing plate 8 is provided to seal the transmission groove 5-1 to prevent heat leakage from affecting the heat treatment effect.
[0054] For example, such as Figure 4 As shown, the door panel 7-2 is sealed and bonded to the outer shell 2 and the surface of the platform 1.
[0055] In some examples, the sealed fit allows the door panel 7-2 to seal the outer shell 2 to the maximum extent, reducing heat loss and improving the heat treatment effect.
[0056] For example, such as Figure 4 As shown, the telescopic cylinder 5-8 can control the material rack 5-5 to rotate upward by 45°.
[0057] In some examples, by rotating upwards by 45°, the material rack 5-5 can be in a fully tilted state, so that no bolts remain in the material rack 5-5, allowing for full material discharge.
[0058] In actual use: Place the bolt in the material rack 5-5, start the motor of the drive screw 5-3, so that the moving seat 5-4 moves the material rack 5-5 to a suitable position in the heat treatment furnace. Close the third cylinder 7-3 of the switch assembly 7, so that the door plate 7-2 is lowered to seal the heat treatment furnace. Start the heating tube 3 to heat treat the bolt. After the heat treatment is completed, open the third cylinder 7-3 to raise the door plate 7-2. Start the drive screw 5-3 again to move the material rack 5-5 out. Start the telescopic cylinder 5-8, and the bracket 5-9 pushes the material rack 5-5 to rotate upward by 45°. The bolt falls into the receiving box 4. Start the water pump 6-6 to water cool the bolt in the receiving box 4. Start the spiral auger 6-2 to discharge the cooled bolt through the discharge pipe 6-1, and the water is discharged through the separation hole 6-3.
