[0027] See also Figures 1 to 5The present invention provides a heat-insulating cover comprising a cover body 100 and at least one door 200. The cover can insulate the forgings 700, reducing heat loss from the forgings 700 and thus saving energy consumption in subsequent heat treatment processes. After a certain number of forgings 700 have accumulated within the cover, they are collectively placed in a heating furnace for heating.

[0029] See also Figures 3 and 4 , there is at least one door body 200, and it can also be set to two, three or more, without limitation. The number of door bodies 200 can be adaptively adjusted according to actual needs. The door body 200 is connected to the cover body 100 in a switchable manner, that is, the door body 200 can be opened and closed. The connection method is not limited and can be rotating opening and closing, up and down opening and closing, pushing and pulling opening and closing, telescopic opening and closing or folding opening and closing, etc.; by setting the door body 200, it is possible to open the door body 200 to take and place the forging 700, which can effectively control the loss of heat in the thermal insulation cover. The door body 200 and the cover body 100 are surrounded by a cavity 230 with an opening at the lower end for accommodating the forged forging 700.

[0030] Further, see Figures 3 and 4 The cover body 100 and / or the door body 200 both include an insulation layer 300. Specifically, the insulation layer 300 can be provided on both the cover body 100 and the door body 200, or the insulation layer 300 can be provided only on the cover body 100, or the insulation layer 300 can be provided only on the door body 200. In either case, the insulation performance of the insulation cover can be achieved. After the high-temperature forging of small and large numbers of rod-shaped forgings 700 is completed, they are placed in the insulation cover for storage before entering the heating furnace. The insulation cover can insulate the forgings 700 and reduce the heat loss of the forgings 700, so as to save energy consumption in subsequent heat treatment processes.

[0031] See also Figures 3 and 4In one example of the heat preservation cover of the present invention, the side wall 120 includes a first side wall 121 and a second side wall 122. The shape of the top wall 110 can be various, such as a rectangle, square, circle, sphere, arc, ellipse or other irregular shapes, which are not limited to this.

The shapes of the first side wall 121 and the second side wall 122 can be various, such as a rectangle, square, circle, arc, sphere, ellipse or other irregular shapes, which are not limited to this. The first side wall 121 and the second side wall 122 are arranged opposite to each other and are connected to the two sides of the top wall 110 and extend downward to form a frame. In this embodiment, the first side wall 121 and the second side wall 122 are both rectangular. The door body 200 is provided with two, specifically, the two ends of the frame are respectively connected to a first door body 210 that can be opened and closed and a second door body 220 that can be opened and closed. The first door body 210 and the second door body 220 are respectively connected to each other. The body 220 is arranged relative to each other, and the door body 200 is connected to the cover body 100 in a switchable manner, that is, the door body 200 can be opened and closed, and the connection method is not limited, and can be rotating opening and closing, up and down opening and closing, pushing and pulling opening and closing, telescopic opening and closing or folding opening and closing, etc. The first door body 210 and the second door body 220 are surrounded by the first side wall 121, the second side wall 122 and the top wall 110 to form the cavity 230. One of the first door body 210 and the second door body 220 is used to place the forging 700, and the other is used to take out the forging 700. This setting is more flexible and less restricted by the site.

[0032] See also Figures 1 to 5 In one example of the heat preservation cover of the present invention, a steel frame structure 240 compatible with the cover body 100 is provided on the outside of the cover body 100. The form of the steel frame structure 240 is not limited, and it can be a portal steel frame, a frame steel frame, a grid steel frame or a box-type steel frame, etc., as long as it can support and protect the cover body 100 to achieve the effect of improving the strength of the cover body 100.

[0033] See also Figure 5In one example of the heat preservation cover of the present invention, a lifting device 400 is further included, and the lifting device 400 includes a first lifting mechanism 410 and a second lifting mechanism 420. The first lifting mechanism 410 and the second lifting mechanism 420 can be in various forms, such as hydraulic lifting, electric lifting, thread lifting, air pressure lifting, rope lifting, chain lifting or telescopic structure lifting, etc., without limitation to this. Furthermore, the first lifting mechanism 410 is arranged on the outside of the first side wall 121, and the first lifting mechanism 410 is simultaneously connected to the first door body 210 and the second door body 220 in a transmission manner, so as to be able to drive the lifting and lowering of one side of the first door body 210 and the second door body 220. The second lifting mechanism 420 is arranged on the outside of the second side wall 122, and the second lifting mechanism 420 is simultaneously connected to the first door body 210 and the second door body 220 in a transmission manner, so as to be able to drive the lifting and lowering of one side of the first door body 210 and the second door body 220. It should be noted that the first lifting mechanism 410 and the second lifting mechanism 420 adopt the same form, which can realize the synchronous lifting and lowering of the first door body 210 and the second door body 220.

[0034] See also Figures 1 to 4 In one example of the heat preservation cover of the present invention, the heat preservation cover further includes a lifting device 400, which includes a third lifting mechanism 430 and a fourth lifting mechanism 440. The third lifting mechanism 430 and the fourth lifting mechanism 440 can be in various forms, such as hydraulic lifting, electric lifting, threaded lifting, air pressure lifting, rope lifting, chain lifting, or telescopic structure lifting, etc., which are not limited to this. Furthermore, the third lifting mechanism 430 is arranged on both sides of the first door body 210 and is transmission-connected to the first door body 210. The fourth lifting mechanism 440 is arranged on both sides of the second door body 220 and is transmission-connected to the second door body 220. It should be noted that the third lifting mechanism 430 and the fourth lifting mechanism 440 can adopt the same form or different forms. In this embodiment, the third lifting mechanism 430 and the fourth lifting mechanism 440 are both controlled by cylinders for lifting and lowering. The specific form can be set with reference to the existing cylinder lifting method. Different from the above-mentioned form in which the first lifting mechanism 410 and the second lifting mechanism 420 control the simultaneous rising and falling of the first door body 210 and the second door body 220, in this embodiment, the third lifting mechanism 430 is used to control the first door body 210, and the fourth lifting mechanism 440 is used to control the rising and falling of the second door body 220. The separate control of the first door body 210 and the second door body 220 can open the corresponding door body 200 as needed to reduce unnecessary heat loss.

[0035] See also Figures 3 and 4In one example of the heat preservation cover of the present invention, the heat preservation cover also includes at least one inclined track 500, which is arranged perpendicular to the door body 200, and the thinner end of the inclined track 500 faces the cavity 230. The shape of the inclined track 500 is not limited, as long as the end facing the cavity 230 is thinner and the end away from the cavity 230 is higher, so as to enable the forging 700 to enter the cavity 230 along the inclined track 500 under the action of its own weight. This setting achieves the effect of guiding the auxiliary forging 700 to enter the cavity 230, thereby improving production efficiency. In addition, after the forging 700 located at the lower end of the inclined track 500 is removed, the forging 700 located at a high place will automatically roll down and be neatly arranged under the action of its own weight, which can improve the problem of the forging 700 being difficult to place due to its own high temperature.

[0036] See also Figures 3 and 4 In an example of the heat preservation cover of the present invention, the inclined track 500 includes an inclined plate 510 and a limiting plate 520. The shape of the limiting plate 520 is not limited and can be a flat plate or a curved plate. The limiting plate 520 is arranged on the path of the forging 700 entering the cavity 230 along the inclined track 500 to limit the forging 700 from entering the cavity 230 and continuing to move forward. It can protect the heat preservation cover from being impacted and is also beneficial to improving the neatness of the stacking of the forgings 700. The limiting plate 520 is directly or indirectly connected to the thinner end of the inclined plate 510. The limiting plate 520 is located in the cavity 230. For example, the limiting plate 520 can be directly connected to the thinner end of the inclined track 500, or it can be indirectly connected to the thinner end of the inclined track 500 through a straight section to achieve a buffering effect on the forging 700.

[0037] See also Figures 3 and 4 In order to make the inclined track 500 have a better guiding effect, in an example of the heat preservation cover of the present invention, the inclined plate 510 is at least partially located in the cavity 230. In order to facilitate the inclined plate 510 to pass through the door body 200, the door body 200 through which the inclined plate 510 passes is provided with a groove 211 allowing the inclined plate 510 to pass through. Specifically, it can be set that the inclined plate 510 passes through one of the first door body 210 or the second door body 220. In this embodiment, the first door body 210 is used to place the forging 700, and the second door body 220 is used to take out the forging 700, so the inclined plate 510 passes through the first door body 210.

[0038] See also Figures 1 to 5In an example of the heat preservation cover of the present invention, the heat preservation cover further includes a moving device 600, and the moving device 600 includes a driving mechanism 610, a walking mechanism 620 and a guide rail 630. The driving mechanism 610 provides a power source for the moving device 600. The driving mechanism 610 can be in various forms, such as a motor, a hydraulic pump, an air compressor, etc. The driving mechanism 610 is fixed to the cover body 100 and is in transmission connection with the walking mechanism 620. The walking mechanism 620 is a mechanism in the moving device 600 that transmits power and performs actions. There are many forms of 20, such as spiral transmission, worm gear transmission, hydraulic cylinder transmission, pneumatic cylinder transmission, etc., which are not limited to this. In order to reduce the friction when the thermal insulation cover moves with the mobile device 600, the walking mechanism 620 is slidingly connected to the guide rail 630. By setting the mobile device 600, when a large number of forgings 700 need to be taken out together, the thermal insulation cover will open the first door body 210 and the second door body 220 at the same time, and move with the mobile device 600, leaving the initial position, exposing all forgings 700 outside the thermal insulation cover, thereby achieving the effect of convenient transfer.

[0039] See also Figures 1 to 5 Furthermore, considering that the heat preservation cover may interfere with pipes and wires when it moves, drag chains 640 are respectively provided on both sides of the cover body 100. The pipes and wires are placed in the drag chains 640 and move with the drag chains 640 when the heat preservation cover moves. The drag chains 640 can protect the pipes and wires.

[0040] See also Figures 3 and 4 Considering that the insulation layer 300 used for the insulation cover requires higher heat resistance, preferably, in an example of the insulation cover of the present invention, the insulation layer 300 includes at least one of rock wool, mineral wool, glass wool, and aluminum silicate wool. This setting can reduce the damage to the steel frame caused by the high temperature generated by the workpiece, and can also reduce heat loss, thereby achieving better insulation effect.

[0041] The utility model has a heat-insulating cover, in which the cover body and the door body are surrounded to form a cavity that can accommodate workpieces, and the door body can be opened and closed, making it convenient to put the workpieces in and out. The cover body and / or the door body include a heat-insulating layer to achieve the heat-insulating performance of the heat-insulating cover. After the high-temperature forging of small and large rod-shaped forgings is completed, they are placed in the heat-insulating cover for storage before entering the heating furnace. The heat-insulating cover can keep the forgings warm, reduce the heat loss of the forgings, and save energy consumption in the subsequent heat treatment process. After the forgings in the heat-insulating cover accumulate to a certain number, they are uniformly placed in the heating furnace for heating, which reduces the frequency of frequent opening of the heating furnace, alleviates the problem of heat loss in the heating furnace, reduces energy waste, and at the same time improves the problem of the performance of the workpiece in the furnace being affected by the unstable temperature in the furnace. Therefore, the utility model effectively overcomes some practical problems in the prior art and has high utilization value and use significance. The above embodiments are only illustrative of the principles and effects of the utility model and are not intended to limit the utility model. Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by persons skilled in the art without departing from the spirit and technical concept disclosed in this utility model shall be covered by the claims of this utility model.
