AI Technical Summary
In existing heating furnace discharge equipment, after the billet is placed directly on the ground, the bottom cannot be easily gripped by the lifting device, which affects the lifting efficiency, and the high temperature of the billet may damage the base material.
A concrete base is used to support the billet. The top surface of the concrete base is smaller than the bottom surface of the billet, so that the bottom of the billet is exposed. The concrete base is raised and lowered by a lifting module. Combined with the design of slide rails and extension edges, stability and smoothness are ensured.
This design allows the billet to be suspended at the bottom, making it easier for the lifting equipment to grip it, preventing the concrete base from being damaged by high temperatures, improving the reliability of lifting and the flexibility of the equipment, and reducing energy consumption and material costs.

Description
Technical Field
[0001] This utility model relates to the field of heating furnace technology, and specifically to a material discharge mechanism for a heating furnace. Background Technology
[0002] A heating furnace is a device used to heat metal blanks. Discharge machinery is required to remove the blanks from the heating furnace. See also... Figure 1 The current discharge machinery includes a base 1, which is made of metal. The base 1 is equipped with a movable seat 2 and a longitudinal drive module 3. The longitudinal drive module 3 is used to drive the movable seat 2 to move longitudinally. The movable seat 2 is equipped with a rotary table 4 and a rotating module 5. The rotating module 5 is used to drive the rotary table 4 to rotate in the horizontal plane. The rotary table 4 is clamped with a module 6.
[0003] The process of removing the billet 7 from the heating furnace 8 is as follows: (1) The longitudinal drive module 3 drives the moving seat 2 to approach the heating furnace along the longitudinal direction, so that the clamping module 6 can extend into the heating furnace 8; (2) The clamping module 6 clamps the billet 7 from the heating furnace 8; (3) The longitudinal drive module 3 drives the moving seat 2 to leave the heating furnace 8 along the longitudinal direction, so that the clamping module 6 drives the billet 7 out of the heating furnace 8; (4) The rotation module 5 drives the rotary table 4 to rotate, so that the billet 7 clamped by the clamping module 6 rotates to one side of the base 1, and the clamping module 6 releases the billet 7 on the ground.
[0004] The reason for placing the billet 7 on the ground is that the heated billet 7 is in a high-temperature state (usually around 1200℃, at which temperature the metallographic structure inside the billet 7 is in an active state, which is convenient for subsequent forging). If the billet 7 is placed on the metal base 1, it will affect the material properties of the base 1.
[0005] After the billet 7 is placed on the ground, it needs to be picked up using the lifting device 9 and transported to the subsequent process. Since the billet 7 is placed directly on the ground, there is no gap between the bottom of the billet 7 and the ground. Therefore, the tips 911 of the two lifting arms 91 in the lifting device 9 cannot easily reach the bottom of the billet 7, making it inconvenient to pick up the billet 7.
[0006] Therefore, how to expose the bottom of the billet to facilitate clamping by the lifting device is a technical problem that needs to be solved. Utility Model Content
[0007] To address the aforementioned shortcomings of the existing technology, this utility model proposes a discharge mechanism for a heating furnace. This utility model allows the bottom of the billet to be exposed, facilitating clamping by the lifting device.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0009] A discharge mechanism for a heating furnace includes a base, a movable seat and a longitudinal drive module on the base. The longitudinal drive module drives the movable seat to move longitudinally. The movable seat is equipped with a rotary table and a rotating module. The rotating module drives the rotary table to rotate in a horizontal plane. A clamping module is mounted on the rotary table and clamps a billet. The base is provided with a mounting hole, and a concrete seat and a lifting module for driving the concrete seat to rise and fall are provided in the mounting hole. The top surface area of the concrete seat is smaller than the bottom surface area of the billet.
[0010] Furthermore, the bottom surface of the concrete seat is provided with a receiving groove, and the lifting module is located in the receiving groove.
[0011] Furthermore, the base has a first wiring groove at its bottom, and the concrete base has a second wiring groove at its bottom, with the first wiring groove, the second wiring groove, and the receiving groove connected in sequence.
[0012] Furthermore, a slide rail is provided on the wall of the mounting hole, and a slide block is provided on the outer wall of the concrete seat, with the slide block slidingly engaging with the slide rail in the vertical direction.
[0013] Furthermore, the top periphery of the concrete seat is provided with an extension edge, which covers the gap between the concrete seat and the mounting hole.
[0014] The beneficial effects of this utility model are:
[0015] 1. In this utility model, a concrete base is used to receive and hold the billet taken out of the heating furnace by the clamping module. Because the top surface area of the concrete base is smaller than the bottom surface area of the billet, after the billet is placed on the concrete base, the bottom periphery of the billet can be exposed from the periphery of the concrete base, so that the bottom periphery of the billet is in a suspended state. When using a lifting tool to clamp the billet, the tip of the lifting arm in the lifting tool can contact the bottom periphery of the billet, which makes it convenient for the lifting tool to clamp the billet.
[0016] 2. By using a concrete base to support the billet, the concrete base will not be damaged by the temperature of the high-temperature billet, which helps to improve the reliability of use.
[0017] 3. By setting the concrete seat in the mounting hole of the base and setting the lifting module in the mounting hole to drive the concrete seat to rise and fall, the concrete seat can be hidden in the mounting hole when not in use. When the longitudinal drive module drives the moving seat to approach the heating furnace, the moving seat will not be obstructed by the concrete seat. There is no need to increase the height of the moving seat to avoid the concrete seat, which improves the flexibility of use.
[0018] 4. By placing the lifting module inside the receiving groove of the concrete base, on the one hand, the weight of the concrete base can be reduced, thereby reducing the load on the lifting module and helping to reduce the energy consumption of the lifting module; on the other hand, the overall height of the concrete base and the lifting module can be reduced, thereby reducing the thickness of the base and helping to save on the material cost of the base; furthermore, placing the lifting module inside the receiving groove can also protect the lifting module.
[0019] 5. By installing slide rails on the wall of the mounting hole and slide blocks on the outer wall of the concrete seat, the stability and smoothness of the concrete seat during lifting can be improved.
[0020] 6. The extension can cover the gap between the concrete seat and the mounting hole, preventing oxide scale and debris from falling in and causing the concrete seat to jam due to oxide scale and debris falling into the gap, which helps to make the concrete seat more stable and smooth during lifting.

Therefore, they should not be construed as limitations on this utility model.
[0045] Example 1:
[0046] See Figure 2 and Figure 3A discharge mechanism for a heating furnace includes a base 1, a movable seat 2 and a longitudinal drive module 3 on the base 1, the longitudinal drive module 3 being used to drive the movable seat 2 to move longitudinally, a rotary table 4 and a rotating module 5 on the movable seat 2, the rotating module 5 being used to drive the rotary table 4 to rotate in a horizontal plane, and a clamping module 6 on the rotary table 4 being used to clamp a blank 7.
[0047] See Figure 2 and Figure 3 The base 1 is also provided with mounting holes 11, within which a concrete seat 20 and a lifting module 30 for driving the concrete seat 20 to rise and fall are disposed. By using the concrete seat 20, the performance of the concrete seat 20 will not be damaged by the temperature of the high-temperature billet 7. The lifting module 30 can be a hydraulic cylinder, or it can be a pneumatic cylinder or an electric push rod. The top surface area of the concrete seat 20 is smaller than the bottom surface area of the billet 7.
[0048] The working principle of this embodiment 1 is as follows:
[0049] (1) The longitudinal drive module 3 drives the moving seat 2 to approach the heating furnace 8 along the longitudinal direction, so that the clamping module 6 can extend into the heating furnace 8; (2) The clamping module 6 clamps the billet 7 from the heating furnace 8; (3) The longitudinal drive module 3 drives the moving seat 2 to leave the heating furnace 8 along the longitudinal direction, so that the clamping module 6 drives the billet 7 out of the heating furnace 8; (4) The lifting module 30 drives the concrete seat 20 to rise, so that the concrete seat 20 is lifted out of the mounting hole 11; (5) The clamping module 6 places the billet 7 on the concrete seat 20. Because the top surface area of the concrete seat 20 is smaller than the bottom surface area of the billet 7, after the billet 7 is placed on the concrete seat 20, the bottom periphery of the billet 7 can be exposed from the periphery of the concrete seat 20, so that the bottom periphery of the billet 7 is suspended. When the lifting device 9 is used to clamp the billet 7, the tip 911 of the boom 91 in the lifting device 9 can contact the bottom periphery of the billet 7, which makes it convenient for the lifting device 9 to clamp the billet 7.
[0050] Based on the above working principle, it can be seen that Embodiment 1 has the following effects:
[0051] First, in this embodiment, a concrete base 20 is used to receive and hold the billet 7 taken out of the heating furnace 8 by the clamping module 6. Because the top surface area of the concrete base 20 is smaller than the bottom surface area of the billet 7, after the billet 7 is placed on the concrete base 20, the bottom periphery of the billet 7 can be exposed from the periphery of the concrete base 20, so that the bottom periphery of the billet 7 is in a suspended state. When the lifting device 9 is used to clamp the billet 7, the tip 911 of the lifting arm 91 in the lifting device 9 can contact the bottom periphery of the billet 7, which makes it convenient for the lifting device 9 to clamp the billet 7.
[0052] Therefore, the discharge mechanism of this embodiment is suitable for situations where the bottom of the boom 91 of the lifting device 9 is provided with a tip 911. The tip 911 can support the bottom of the billet 7, thereby improving the reliability of the lifting device 9 in lifting the billet 7.
[0053] Secondly, by using the concrete seat 20 to support the billet 7, the concrete seat 20 will not be damaged by the temperature of the high-temperature billet 7, which helps to improve the reliability of use.
[0054] Third, in this embodiment, by setting the concrete seat 20 in the mounting hole 11 of the base 1 and setting the lifting module 30 in the mounting hole 11 to drive the concrete seat 20 to rise and fall, the concrete seat 20 can be hidden in the mounting hole 11 when it is not in use. When the longitudinal drive module 3 drives the moving seat 2 to approach the heating furnace 8, the moving seat 2 will not be obstructed by the concrete seat 20. There is no need to increase the height of the moving seat 2 in order to avoid the concrete seat 20, which improves the flexibility of use.
[0055] For further improvements, see Figure 5 , Figure 7 and Figure 9 The bottom surface of the concrete base 20 is provided with a receiving groove 201, and the lifting module 30 is located in the receiving groove 201. The bottom of the base 1 is provided with a first wiring groove 12, and the bottom of the concrete base 20 is provided with a second wiring groove 202. The first wiring groove 12, the second wiring groove 202, and the receiving groove 201 are connected in sequence. When the lifting module 30 uses a hydraulic cylinder, the oil pipe connected to the hydraulic cylinder can extend to the outside of the base 1 through the second wiring groove 202 and the first wiring groove 12 in sequence.
[0056] By placing the lifting module 30 within the receiving groove 201 of the concrete base 20, the weight of the concrete base 20 can be reduced, thereby reducing the load on the lifting module 30 and thus lowering its energy consumption. Furthermore, the overall height of the concrete base 20 and the lifting module 30 can be reduced, thereby decreasing the thickness of the base 1 and saving on material costs. Finally, placing the lifting module 30 within the receiving groove 201 also provides protection for the lifting module 30.
[0057] To ensure greater stability and smoothness during the lifting and lowering of the concrete seat 20, see [link / reference]. Figure 5 and Figure 7 A slide rail 111 is fixedly installed on the wall of the mounting hole 11, and a slide block 203 is fixedly installed on the outer wall of the concrete seat 20. The slide block 203 slides in a vertical direction with the slide rail 111.
[0058] To prevent scale and debris from falling into the gap between the concrete base 20 and the mounting hole 11, see... Figure 9The top periphery of the concrete seat 20 is provided with an extension edge 204, which is an integral structure with the concrete seat 20. The extension edge 204 can cover the gap between the concrete seat 20 and the mounting hole 11, preventing oxide scale debris from falling in and preventing the concrete seat 20 from getting stuck due to oxide scale debris falling into the gap. This helps to make the concrete seat 20 more stable and smooth when it is raised and lowered.
[0059] Example 2
[0060] This embodiment 2 illustrates the specific structures of the longitudinal drive module 3, the rotary module 5, and the clamping module 6 in embodiment 1:
[0061] See Figures 2 to 4 The longitudinal drive module 3 includes a guide rail 31, a rack 32, a longitudinal drive gear 33, and a longitudinal drive motor 34. The guide rail 31 and the rack 32 are both fixedly mounted on the base 1. The movable seat 2 is slidably connected to the guide rail 31 along the longitudinal direction. The longitudinal drive motor 34 is a servo motor and is fixedly mounted on the movable seat 2. The longitudinal drive gear 33 is fixedly mounted on the output shaft of the longitudinal drive motor 34, and the longitudinal drive gear 33 meshes with the longitudinal drive rack 32.
[0062] The working principle of the longitudinal drive module 3 driving the moving seat 2 to move longitudinally is as follows: When the longitudinal drive motor 34 drives the longitudinal drive gear 33 to rotate forward, the longitudinal drive gear 33 drives the moving seat 2 to move forward longitudinally and approach the heating furnace 8, so that the moving seat 2 can drive the clamping module 6 to extend into the heating furnace 8 to clamp the billet 7. When the longitudinal drive motor 34 drives the longitudinal drive gear 33 to rotate in reverse, the longitudinal drive gear 33 drives the moving seat 2 to move backward longitudinally away from the heating furnace 8, so that the moving seat 2 can drive the clamping module 6 to exit the heating furnace 8, so that the billet 7 can be taken out of the heating furnace 8.
[0063] See Figure 9 The rotating module 5 includes a gear ring 51, a rotating gear 52, and a rotating motor 53. The rotating gear ring 51 is fixedly mounted on the top surface of the movable base 2. See also... Figure 10 The rotary table 4 has a central shaft 41 at its bottom, and the rotary table 4 and the central shaft 41 are an integral structure. The central shaft 41 rotates with the inner ring of the gear ring 51. The bottom of the central shaft 41 passes through the movable seat 2, and a limit ring 411 is fixedly installed at the bottom of the central shaft 41. The limit ring 411 is located on the bottom surface of the movable seat 2 and can prevent the central shaft 41 from being pulled upward away from the gear ring 51, thereby improving the reliability of the rotational engagement between the central shaft 41 and the gear ring 51. The rotary motor 53 is a servo motor, which is fixedly installed on the rotary table 4. A rotary gear 52 is fixedly installed on the output shaft of the rotary motor 53, and the rotary gear 52 meshes with the gear ring 51.
[0064] The working principle of the rotary module 5 driving the rotary table 4 to rotate in the horizontal plane is as follows: When the rotary motor 53 drives the rotary gear 52 to rotate clockwise, the rotary gear 52 drives the rotary table 4 to rotate clockwise around the gear ring 51 in the horizontal plane; when the rotary motor 53 drives the rotary gear 52 to rotate counterclockwise, the rotary gear 52 drives the rotary table 4 to rotate counterclockwise around the gear ring 51 in the horizontal plane. By allowing the rotary table 4 to rotate in the horizontal plane, the angle of the clamping module 6 on the rotary table 4 in the horizontal plane can be adjusted, so as to expand the clamping range that the clamping module 6 can clamp, which is beneficial to improving the flexibility of use.
[0065] See Figure 8 The clamping module 6 includes a bracket 61, a clamping telescopic rod 62, a drive rod 63, a sliding sleeve 64, and a clamping arm 65. The clamping telescopic rod 62 is fixedly mounted on the bracket 61. The clamping telescopic rod 62 can be a hydraulic cylinder. Two drive rods 63 are rotatably connected to the output end of the clamping telescopic rod 62. Sliding sleeves 64 are rotatably connected to the ends of the two drive rods 63 away from the clamping telescopic rod 62. The sliding sleeves 64 are slidably connected to the crossbar 611 on the bracket 61. The clamping arms 65 are fixedly mounted on both sliding sleeves 64.
[0066] The operating principle of the clamping module 6 in clamping the blank 7 is as follows: When the output end of the clamping telescopic rod 62 extends, it pushes the two drive rods 63 closer to the crossbar 611, increasing the angle between the two drive rods 63, the distance between the two sliding sleeves 64, and the distance between the two clamping arms 65. When the output end of the clamping telescopic rod 62 retracts, it pushes the two drive rods 63 away from the crossbar 611, decreasing the angle between the two drive rods 63, the distance between the two sliding sleeves 64, and the distance between the two clamping arms 65.
[0067] In addition, see 2 and Figure 3 The rotary table 4 is also equipped with an adjustment module 10, which is used to adjust the tilt angle of the clamping module 6. The adjustment module 10 includes an adjusting telescopic rod 101 and a support base 102. The adjusting telescopic rod 101 can also be a hydraulic cylinder. The output end of the adjusting telescopic rod 101 is set upwards, and the lower end of the adjusting telescopic rod 101 is rotatably mounted on the rotary table 4. The output end of the adjusting telescopic rod 101 is rotatably connected to the upper end of the support base 102, and the lower end of the support base 102 is rotatably connected to the rotary table 4. The bracket 61 in the clamping module 6 is fixedly mounted on the upper end of the support base 102.
[0068] The working principle of adjusting the tilt angle of the clamping module 6 by adjusting module 10 is as follows: When the output end of the adjusting telescopic rod 101 extends, it pushes the support base 102 to swing downwards. The support base 102 then causes the clamping module 6 to swing downwards, reducing the clamping height of the clamping module 6, making it easier to clamp the blank 7 with a lower clamping height. When the output end of the adjusting telescopic rod 101 retracts, it pulls the support base 102 upwards, causing the support base 102 to swing the clamping module 6 upwards, increasing the clamping height of the clamping module 6, making it easier to clamp the blank 7 with a higher clamping height. This improves the flexibility of use.
[0069] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
