[0024] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.
[0025] See also Figure 1 The utility model provides a lifting device for a hot forming heating furnace. The lifting device for a hot forming heating furnace comprises a base 1, a lifting knife 2 and a lifting mechanism 3. The base 1 has a plurality of connecting parts 11 arranged in a matrix. A plurality of lifting knives 2 are detachably connected to each connecting part 11, respectively. These lifting knives 2 are arranged in multiple rows and can pass through two rollers of the furnace discharge roller. The lifting mechanism 3 is connected to the base 1 in a transmission manner to drive the lifting knife 2 to perform a lifting movement through the base 1, and lift the workpiece 9 so that the workpiece 9 can be clamped and transported away by a robot arm or other equipment.
[0026] The base 1 of the lifting device for the hot forming heating furnace provided by the utility model can disassemble and install the lifting knife 2 according to the needs of the production products, so as to avoid the collision between the lifting knife 2 and the positioning baffle plate, the manipulator clamp and other movable parts on the furnace roller. A single lifting knife 2 is small in size and light in weight, and can be quickly installed and disassembled, thereby improving the working efficiency and reducing the labor intensity of the workers.
[0027] See also Figure 2 In some embodiments, the connection portion 11 of the base 1 is a socket extending vertically, and the lifting blade 2 is plugged into the socket. The sockets are preferably evenly distributed.
[0028] See also Figure 3 In some embodiments, the upper end of the lifting knife 2 is serrated. This design is adopted so that when carrying the workpiece 9, only the upper end of the sawtooth contacts the workpiece 9, thereby reducing the contact area between the sawtooth and the workpiece 9 and reducing the heat loss of the workpiece 9 caused by contact.
[0029] In a preferred embodiment, the single sawtooth 21 of the lifting knife 2 is trapezoidal, that is, the top of the sawtooth 21 is sharpened and flattened to ensure strength and safety and prevent sharp corners from wearing out quickly.
[0030] In some embodiments, a plug-in portion 22 is formed at the lower end of the lifting blade 2, and the plug-in portion 22 is plugged into the socket, i.e., the connecting portion 11. When a lifting blade 2 has multiple plug-in portions 22, the spacing between these plug-in portions 22 enables all the plug-in portions 22 to be inserted into the socket.
[0031] See also Figures 3 to 5 In a preferred embodiment, the lifting knife 2 further includes a fixing member 23 for fixing the lifting knife 2 when the lifting knife 2 is inserted into the insertion hole. The fixing member 23 includes a shell 231, a bead 232 and a spring 233. The plug-in portion 22 is formed with a mounting hole, the shell 231 is fixedly built into the mounting hole, a through hole is formed at one end of the shell 231, the bead 232 is spherical and built into the shell 231, the diameter of the bead 232 is larger than the diameter of the through hole, so that the bead 232 can only partially pass through the through hole, the spring 233 is built into the shell 231, and the two ends of the spring 233 are respectively connected to the bead 232 and the shell 231.
[0032] When inserting the plug-in part 22 into the jack, push the bead 232 back into the shell 231, so that the plug-in part 22 can pass through the jack smoothly. After passing through the jack, the external force disappears, and the bead 232 is pushed out under the elastic force of the spring 233, so that the bead 232 partially passes through the through hole and blocks the lower end of the jack to achieve fixation. When removing the lifting knife 2, push the bead 232 back into the shell 231, and the lifting knife 2 can be pulled out.
[0033] See also Figure 3 In a preferred embodiment, the lifting knife 2 has a plurality of fixing members 23, some of which are located above the insertion hole, and the other fixing members 23 are located below the insertion hole. The fixing members 23 can fix the lifting knife 2 from both the upper and lower directions, so that each lifting knife 2 is at a uniform height.
[0034] In a preferred embodiment, the lifting knife 2 has a plurality of fixing members 23, the beads 232 of a portion of the fixing members 23 face one side of the lifting knife 2, and the beads 232 of another portion of the fixing members 23 face the other side of the lifting knife 2. The fixing members 23 can fix the lifting knife 2 from both sides, so that the force on the lifting knife 2 is more balanced.
[0035] Please see again Figure 1 and Figure 2 In a preferred embodiment, there can be multiple types of lifting knives 2, which have the same saw teeth 21, plug-in parts 22 and fixing members 23, but only different lengths. By combining lifting knives 2 of different lengths, the production needs of multiple types of workpieces 9 can be met.
[0036] Please see again Figure 1 In some embodiments, the lifting mechanism 3 includes a motor 31, a main eccentric wheel 32, a secondary eccentric wheel 33, a mounting seat 34, a main rod 35 and a column 36. The main eccentric wheel 32 is fixedly connected to the transmission shaft of the motor 31, and the secondary eccentric wheel 33 is rotatably connected to the mounting seat 34. The mounting seat 34 is fixedly installed at a suitable position on the frame, the ground or the wall. One end of the main rod 34 is eccentrically rotatably connected to the main eccentric wheel 32, and the other end is eccentrically rotatably connected to the secondary eccentric wheel 33. The upper end of the column 35 is fixedly connected to the base 1, and the lower end is eccentrically rotatably connected to the secondary eccentric wheel 33. The motor 31 can drive the secondary eccentric wheel 33 to rotate around the mounting seat 34 through the main rod 25, thereby driving the column 36 to make an arc motion. Thereby, the lifting and lowering movement of the base 1 is realized in the vertical direction. Since the lifting knife 2 has a margin in both the left and right directions when lifting the workpiece 9, the movement of the column 36 making an arc motion in the horizontal direction will not cause negative effects.
[0037] In a preferred embodiment, the lifting mechanism 3 further includes a plurality of secondary eccentric wheels 32, a plurality of mounting seats 34, a plurality of columns 35 and a plurality of secondary rods 37. Each secondary eccentric wheel 32 is rotatably mounted on a mounting seat 34, and both ends of the secondary rod 37 are eccentrically rotatably connected to two adjacent secondary eccentric wheels 32. The columns 35 correspond to the secondary eccentric wheels 32 one by one, the upper ends are fixedly connected to the base 1, and the lower ends are eccentrically rotatably connected to the secondary eccentric wheels 32. The plurality of columns 35 support a base 1, which can make the base 1 more stable when lifting.
[0038] Compared with the prior art, the utility model provides a lifting device for a hot forming heating furnace with a plurality of lifting knives detachably mounted on its base, which can be disassembled and installed according to the needs of the production products. A single lifting knife is small in size and light in weight, and can be quickly installed and disassembled, thereby improving work efficiency and reducing the labor intensity of workers.
[0039] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
