Description

Technical Field

[0001] The utility model relates to the technical field of metal processing, in particular to a heat preservation device for a discharge port of an aluminum alloy pre-forging heating furnace. Background Art

[0002] Aluminum alloy pre-forging heating furnace is a heating furnace or heat treatment furnace required for aluminum alloy heating and forging. During the aluminum alloy forging process, temperature is crucial for aluminum alloy materials. However, traditional pre-forging heating equipment has an obvious problem: when the aluminum alloy is discharged from the discharge port after heating, the moment the furnace door is opened, the surrounding air will be sucked into the furnace with the negative pressure inside the furnace, causing the temperature at the discharge port to drop rapidly. If the furnace door is opened and closed for a long time, it is bound to lead to temperature instability at the discharge port, resulting in a decline in the overall forging quality of the aluminum alloy material, affecting the overall forging quality.

[0003] Therefore, based on the original aluminum forging heating furnace, developing a discharge port insulation device that can effectively maintain the temperature of aluminum alloy is of great significance to improving the forging quality of aluminum alloy. Utility Model Content

[0009] Preferably, heat-insulating cotton is laid on the inner side walls of the side baffles and the horizontal baffle portion respectively.

[0010] Preferably, the rectangular portion and the horizontal baffle portion are both hollow and filled with thermal insulation cotton.

[0011] Preferably, a cover is fixedly mounted on the upper end surface of the rectangular portion.

[0012] The advantages and positive effects of the utility model are:

[0025] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0026] See also Figure 1-4The present invention provides an embodiment of an insulation device for the discharge port of an aluminum alloy heating furnace before forging, comprising a channel steel frame 33 and a heating furnace 34, wherein a furnace door 17 is installed at the discharge port of the heating furnace 34, and the furnace door 17 is opened to take in and discharge materials from the heating furnace 34. At this time, the upper end surface of the channel steel frame 33 is fixedly installed with side baffles 10 on the left and right sides of the discharge port of the heating furnace 34, and horizontal baffle parts 12 are fixedly installed at the upper and lower positions between the rectangular parts 11 of the side baffles 10, and a through opening is formed between the two horizontal baffle parts 12, which corresponds to the discharge port of the heating furnace 34. At the same time, a furnace door outer shield 14 is slidably installed between the two rectangular parts 11. The outer shield plate 14 of the furnace door is tightly attached to the rear end surface of the horizontal baffle portion 12. The outer shield plate 14 of the furnace door can completely cover the through opening, and the top is sealed with a cover 16, so that the discharge port of the heating furnace 34 is completely wrapped, so that the opening and closing of the furnace door 17 are both carried out inside the wrapping. In order to facilitate the opening of the furnace door 17, a slide 21 is fixedly installed on the upper end surface of the channel steel frame 33 at the inner position of each of the side baffles 10, and a fixing plate 22 is fixedly installed on the upper end surface of the two slides 21. A lifting cylinder 23 is fixedly installed on the fixing plate 22. A telescopic part 20 is installed at the output end of the lifting cylinder 23. The lower end surface of the telescopic part 20 is fixedly connected to the furnace door 17 at the discharge port of the heating furnace 34.

[0027] The furnace door 17 is driven by the lifting cylinder 23 to move up and down and open. Since the discharge port of the heating furnace 34 is fully covered by the side baffles 10, the horizontal baffle part 12, the furnace door outer shield 14 and the cover 16, each time the material is taken in or discharged, the furnace door 17 is opened first, and the external furnace door outer shield 14 is temporarily not opened. When the furnace door 17 is opened, the temperature in the furnace diffuses outward, and since the discharge port is fully covered, the temperature cannot be dissipated, and the external cold air cannot enter in a large amount. At this time, the trace cold air entering can be ignored, so that the temperature diffused out of the furnace is all covered, so that the raw materials in the furnace will not be exposed to the cold air for the first time when the furnace door 17 is opened, resulting in a temperature drop, thereby effectively avoiding the quality problem of the raw materials at the discharge port. After a short stay, the furnace door outer shield 14 is opened to take the material at the discharge port.

[0028] It is worth mentioning that in order to further facilitate the removal of materials from the heating furnace 34 and open the furnace door, in this embodiment, sliders 18 are fixedly installed on both sides of the furnace door 17, each of the sliders 18 is slidably installed in the corresponding slide 21, and two protruding plates 15 are fixedly installed on the rear end surface of the furnace door outer shield 14, and a connecting plate 19 is fixedly installed on the upper end surface of the furnace door 17 at a vertical position of the protruding plate 15. When the furnace door 17 slides upward, the connecting plate 19 It can abut against the protruding plate 15, so that when the lifting cylinder 23 is driven to pull the furnace door 17 up and open it, the speed at which the furnace door 17 moves upward is controlled. After the furnace door 17 gradually rises and opens, it continues to move upward, so that the connecting plate 19 abuts against the protruding plate 15, thereby driving the outer shield plate 14 of the furnace door to move upward, thereby opening the outer shield plate 14 of the furnace door to take materials. By controlling the speed at which the furnace door 17 moves upward, the time for the outer shield plate 14 of the furnace door to close after the furnace door 17 is opened can be controlled.

[0029] It should be noted that in order to further improve thermal insulation, in this embodiment, thermal insulation cotton is laid on the inner walls of the side baffle 10 and the horizontal baffle portion 12 respectively, and at the same time, the rectangular portion 11 and the horizontal baffle portion 12 are both hollow and filled with thermal insulation cotton. The top of the horizontal baffle portion 12 is covered by the cover portion 13.

[0030] During specific implementation, when it is necessary to take materials, the lifting cylinder 23 is driven to drive the furnace door 17 to slide upward, so that the discharge port is opened and the temperature in the furnace diffuses outward. Since the discharge port is wrapped in all directions, the temperature cannot be dissipated, so that the raw materials in the furnace will not be exposed to cold air for the first time when the furnace door 17 is opened, resulting in a drop in temperature, thereby effectively avoiding quality problems of the raw materials at the discharge port. When the furnace door 17 continues to move upward, the connecting plate 19 abuts against the convex plate 15, thereby driving the furnace door outer shield 14 to move upward, thereby opening the furnace door outer shield 14 to take materials.

[0031] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive. Therefore, the present invention is not limited to the embodiments described in the specific implementation methods. Any other implementation methods derived by those skilled in the art based on the technical solution of the present invention also fall within the scope of protection of the present invention.
