Description

Technical Field

[0001] The present invention relates to the technical field of forging, and particularly relates to an aluminum alloy forging device and a using method thereof. Background Art

[0002] Forging refers to an object produced by forging metal at a red-hot state through equipment such as a forging hammer or a press. Forging processing can ensure the continuity of the metal fiber structure, make the fiber structure of the forging consistent with the forging shape, the metal streamline is complete, the structure is dense, and the mechanical properties are good.

[0003] During the forging process of a forging, it needs to be maintained at a certain forging temperature. The forging equipment of the prior art is formed as an open type. Due to heat exchange and other reasons, after the forging is forged for a period of time, the temperature drops below the forging temperature. At this time, the forging conditions cannot be met or the work done on the forging under the action of the same forging force is reduced. To restore the temperature of the forging to the forging temperature range, it is usually necessary to reheat and raise the temperature of the forging. This forging method has low processing efficiency, and due to the large temperature change during the forging process, after the forging is repeatedly heated, it is not conducive to the grain refinement of the forging, affecting the later anodic oxidation coating effect.

[0053] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

The terms such as "upper", "lower", "left" and "right" are only used to represent relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship also changes accordingly.

[0055] First, below in combination with the attached Figure 1-10Specifically, the aluminum alloy forging equipment according to the embodiments of the present invention includes a forging machine body 100, the forging machine body 100 includes a forging hammer 110, four columns 120, and a forging hammer driving assembly 130 disposed on the columns 120. The forging hammer 110 reciprocates up and down between the columns 120, and a forging platform 140 for placing forgings is disposed at the bottom of the forging hammer 110; the heat preservation assembly 200 includes a heat preservation movable door 220, and the heat preservation movable door 220 is disposed at the position of the opening 150 between any two columns 120. The heat preservation movable door 220 can be lifted up and down to open or close the opening 150; guiding portions 210 are respectively disposed on both sides of the heat preservation movable door 220, and a covering plate that wraps the columns 120 is disposed outside the columns 120. The covering plate is vertically disposed, and the guiding portions 210 are disposed on the covering plate. That is to say, as Figure 1 , Figure 2 shown, during the forging process, by lifting the heat preservation movable door 220 up and down along the guiding portions 210, the heat preservation movable door 220 can close the opening 150 on the forging machine body 100, thereby playing a role in heat preservation for the forgings during the forging process, helping to maintain the temperature of the forgings within a better forging temperature range, and improving the processing efficiency and forging quality.

[0056] During forging, if existing forging equipment (such as a hydraulic forging machine with the model YQ34 - 315T produced by Tianjin Tianyi Hydraulic Machinery Technology Co., Ltd.) and forging processes are used, after the forgings are forged for a period of time, the heat of the forgings is lost, and the temperature is lower than the reasonable forging temperature. It is necessary to reheat the forgings to the reasonable forging temperature in a furnace and then forge again. Usually, the single heating time is relatively long, 1h - 2h, and the entire forging process needs to be heated four to five times, and the overall forging time is about 8h, so the forging efficiency is relatively low. At the same time, non - continuous forging is likely to cause the formation of coarse - grained structures or even coarse - grained bands inside the forgings. Before anodizing, the forgings will remove a large amount of oxide films on the surface by pickling or mechanical processing. If there are coarse grains inside the forgings, they will be revealed. When anodizing and coating, non - uniform regions will be generated, which is not conducive to improving the overall corrosion resistance and breakdown resistance of the coating. Figure 9 The metallographic diagram of the aluminum alloy forgings after non - continuous forging is shown. It can be seen from the figure that there are coarse grains in the aluminum alloy forgings after non - continuous forging.

[0057] Compared with the present invention, the forging of the present invention is formed by continuous forging under temperature compensation, which can improve the uniformity of the grains of the forgings and avoid the formation of coarse - grained structures or coarse - grained bands inside the forgings after forging. Forgings with uniform grains can not only improve the comprehensive mechanical properties of the forgings, but also ensure that the anodizing speeds at different grain positions tend to be the same, ensuring the uniformity of the anodized film. Furthermore, the uniform growth of the anodized film, especially the oxalic acid anodized film, is beneficial to ensuring the consistency of the film thickness and is beneficial to improving the overall corrosion resistance and breakdown resistance of the film. Figure 10The metallographic diagram of the aluminum alloy forging after continuous forging is shown. It can be seen from the figure that after continuous forging of the aluminum alloy forging, a forging with refined and uniform grains can be obtained.

[0058] Further, the guiding part 210 is formed as a guide rail 211 arranged along the height direction of the column 120. A guiding groove 212 is arranged on the side of the guide rail 211 facing the heat preservation movable door 220. The side edge of the heat preservation movable door 220 is movably arranged in the guiding groove 212. That is to say, as Figure 2 shown, the heat preservation movable door 220 can move up and down along the height direction parallel to the column 120 on the guide rail 211. Thus, when it is necessary to heat-preserve the forging during forging, the heat preservation movable door 220 can be lowered to the opening 150 of the forging machine body 100, and then a relatively enclosed space is formed inside the forging machine body 100 to avoid the heat of the forging from overflowing. The guiding groove 212 plays a guiding role, and through the sliding fit between the guide rail 211 and the guiding groove 212 or by arranging rollers on the outer edge of the heat preservation movable door 220 for rolling fit, the heat preservation movable door 220 can be prevented from jamming during the up and down movement, further improving the processing efficiency.

[0059] Further, the heat preservation assembly 200 further includes a winding part 230 and a steel wire rope 240. The winding part 230 is arranged on the forging machine body 100; one end of the steel wire rope 240 is connected to the heat preservation movable door 220, and the other end is connected to the winding part 230. The steel wire rope 240 can be wound in or released by the winding part 230 to open or close the opening 150 with the heat preservation movable door 220. That is to say, by controlling the winding in or release of the steel wire rope 240 by the winding part 230 to drive the heat preservation movable door 220 to move up and down, and then the opening 150 is opened or closed. As Figure 2 shown, when the winding part 230 winds the steel wire rope 240, the steel wire rope 240 drives the heat preservation movable door 220 to move upward, and the heat preservation movable door 220 coincides with the outer side of the forging hammer 110, and the opening 150 is in an open state; when the winding part 230 releases the steel wire rope 240, the steel wire rope 240 drives the heat preservation movable door 220 to move downward, and the heat preservation movable door 220 moves towards the position of the opening 150 until the opening 150 is closed. Driving the heat preservation movable door 220 to move up and down by the winding part 230 and the steel wire rope 240 has the advantage of convenient operation.

[0060] The heat preservation assembly 200 further includes a control part 250. The control part 250 is arranged on the cladding plate. The control part 250 includes a switch, and the switch is used to control the start and stop of the winder 232; there are four heat preservation assemblies 200, which are respectively arranged around the forging machine body 100, and the control part 250 of each heat preservation assembly 200 is connected to the corresponding winder 232. That is to say, as Figure 1As shown in the figure, by setting a switch to control the start and stop of the rewinder 232, the wire rope 240 is further controlled to be wound into the rewinder 232 or released from the rewinder 232, so that the heat preservation movable door 220 rises or falls along the height direction of the column 120, and then the opening 150 on the forging machine body 100 is opened or closed. Moreover, on the premise that there are four open openings 150 around the forging machine body 100, four heat preservation assemblies 200 can be correspondingly arranged around the forging machine body 100, and the control parts 250 of each heat preservation assembly 200 respectively control the heat preservation movable doors 220 on each surface to independently control the lifting of the heat preservation movable doors 220, further avoiding the temperature spillage of the forgings and improving the processing efficiency. This is also considering that in the actual forging process, it is usually necessary to keep at least one side of the opening 150 in an open state to facilitate the operator to align the position, angle and control the forging frequency of the forgings through the opening 150. By respectively setting independent control parts 250 to control the movement of the heat preservation movable doors 220, the operation convenience and production efficiency can be further improved.

[0061] Furthermore, the winding part 230 includes a wire passing wheel 231 and a rewinder 232. The wire passing wheel 231 is arranged above the heat preservation movable door 220; the rewinder 232 is arranged on the covering plate below the wire passing wheel 231. The other end of the wire rope 240 extends upward to one side of the wire passing wheel 231, and then winds around to the other side of the wire passing wheel 231 and extends downward to the rewinder 232. That is to say, one end of the wire rope 240 is connected to the heat preservation movable door 220, and the other end of the wire rope 240 is connected to the rewinder 232 through the wire passing wheel 231. By setting the wire passing wheel 231, the wire rope 240 can be prevented from slipping off, and the reliability of the up and down lifting of the heat preservation movable door 220 can be improved.

[0062] Furthermore, the heat preservation movable door 220 is formed as a component made of fireproof and flame-retardant materials. That is to say, the heat preservation movable door 220 with fireproof and flame-retardant properties is set to improve the reliability of the forging equipment. The fireproof and flame-retardant materials can be, for example, high-strength steel, aluminum, etc.

[0063] As some embodiments of the present invention, one cushion plate 141 is respectively arranged on both sides of the forging platform 140, and a temperature compensation component 300 is arranged on the cushion plate 141. That is to say, as Figure 3 shown, one cushion plate 141 is respectively arranged on both sides (corresponding to the front side and the rear side of Figure 3 ) of the forging platform 140 of the forging machine body 100, and the temperature compensation component 300 is arranged on the cushion plate 141, so that the temperature compensation components 300 on the front and rear sides are aligned with the forgings to simultaneously perform temperature compensation on the forgings, which can further prevent the temperature of the forgings from dropping below the required forging temperature during the forging process, and further improve the processing efficiency and forging quality.

[0064] Further, the temperature compensation component 300 includes a spray gun 310 and a spray gun bracket 320. The jet orifice of the spray gun 310 is configured to face the forging. The bottom of the spray gun bracket 320 is connected to the backing plate 141. A gripper 321 that cooperates with the spray gun 310 is formed at the top of the spray gun bracket 320. There are multiple spray guns 310. The end portions of each spray gun 310 are respectively disposed on the corresponding spray gun bracket 320, and the spray gun 310 is installed on the spray gun bracket 320 so that the jet orifice of the spray gun 310 is aligned with the forging. During the forging process, the spray gun 310 can be started at regular intervals to apply a high-temperature heat source to the forging with the spray gun 310. The interval time depends on the ambient temperature and the forging temperature. The interval time can be, for example, 10 minutes or 15 minutes. By making the jet orifice of the spray gun 310 face the forging to apply a high-temperature heat source, the heat absorption efficiency of the forging is improved, thereby further improving the processing efficiency.

[0065] As another embodiment of the present invention, the aluminum alloy forging equipment of the embodiment of the present invention may further include two first channels 160 and two second channels 170. The two first channels 160 are respectively disposed on the front side and the rear side of the forging platform 140. The first channel 160 has an opening 161 facing upward; the two second channels 170 are respectively disposed on the left and right sides of the forging platform 140. A blower 500 is provided in the second channel 170. The blower 500 is used to blow air flow from the second channel 170 to the opening 161 of the first channel 160. That is to say, as Figure 5 shown, a first channel 160 is provided on each of the front side and the rear side of the forging platform 140 of the forging machine body 100, and second channels 170 that can communicate with the first channel 160 are further respectively provided on the left and right sides of the forging machine body 100. The gas from outside the forging machine body can enter the second channel 170 through the blower 500, and under the action of the blower 500 in the second channel 170, the air flow enters the second channel 170 from the outside, enters the first channel 160 from the second channel 170, and is discharged above the forging platform 140 through the opening 161 on the first channel 160 (defining this air flow as the first air flow A). It should be noted that Figure 7 the dots in indicate that the flow direction of the first air flow A in the first channel 160 is perpendicular to the paper surface and outward, that is, flowing toward the inner cavity of the forging machine body 100. This structure enables the hot air flow emitted by the forging to gather above the front side of the forging machine body 100. The front side of the forging machine body 100 is an open front for the worker operation area 001. Such a design drives the forging hot air B (defined as the forging hot air B) that was originally discharged from the open front of the forging machine body 100 to the upper area between the worker operation area 001 and the open front of the forging machine body 100 through the first air flow A, avoiding the forging hot air B directly entering the worker operation area 001 and causing harm to the worker, and further improving the convenience and safety of the operation.

[0066] For the two first flow channels 160 respectively arranged on the front side and the rear side of the forging platform 140, generally during operation, only one first flow channel 160 is opened, and the other first flow channel 160 can be blocked by a cover plate or a blocking block. The previous paragraph describes the first flow channel 160 on the front side of the forging platform 140 that is opened, and the first flow channel 160 on the rear side of the forging platform 140 is in a closed state, and accordingly, the heat-insulating movable door 220 on the rear side of the forging platform 140 is also in a closed state. If according to actual operation needs, the first flow channel 160 on the front side can be closed, and the heat-insulating movable door 220 on the front side can also be closed, and the first flow channel 160 on the rear side can be opened, and the heat-insulating movable door 220 on the rear side can also be opened to realize the switching of the operation window. At this time, the worker's operation area is switched to the rear opening of the forging body.

[0067] As some embodiments of the present invention, the aluminum alloy forging equipment may further include a heat source recovery component 600, which includes an air suction hood 610, a third flow channel 620 and a negative pressure fan 630. The air suction hood 610 is arranged on the heat-insulating movable door 220, and the air suction port of the air suction hood 610 is arranged toward the opening 161. One end of the third flow channel 620 is connected to the air outlet of the air suction hood 610, and the other end of the third flow channel 620 is arranged toward the spray gun 310. The negative pressure fan 630 is arranged at the air outlet of the air suction hood 610, and the negative pressure fan 630 is used to guide the gas into the other end of the third flow channel 620. In other words, Figure 4-8 As shown, after the first airflow A is discharged from the opening 161, it flows upward, corresponding to Figure 6 , Figure 6 The dots in the figure indicate that the first airflow A flows in the first flow channel 160 in a direction perpendicular to the paper and outward. During the flow, the forging hot air B overflowing from the opening 150 and the oxygen-carrying air C in the worker operation area 001 are mixed (defined as mixed hot air D) and continue to move upward until they meet the suction hood 610; a part of the mixed hot air D (defined as the recovered part D1 of the mixed hot air) is absorbed by the suction hood 610, and the other part (defined as the released part D2 of the mixed hot air) is discharged into the space above the suction hood 610 to mix with the air and cool.

[0068] like Figure 4-8As shown in the figure, on the one hand, the mixed hot gas is sucked into the third flow channel 620 by the recovery part D1, and the gas in the third flow channel 620 is guided to flow towards the other end of the third flow channel 620 to provide oxygen for the spray gun 310, thereby supporting the combustion of the combustible gas in the spray gun 310. On the other hand, the mixed hot gas recovery part D1 has a temperature higher than the normal temperature (due to the presence of forging hot gas in the mixed hot gas), which plays a role in preheating the combustible gas. That is to say, the heat overflowing from the open port 150 is re-adsorbed by the heat source recovery component 600, and a part of it returns to the inside of the forging machine body 100, realizing a certain proportion of internal heat circulation. At the same time, the oxygen required for the spray gun combustion (a part of the external air is carried by the air from the outlet to the suction hood 610, and this part of the air contains oxygen) is brought back to the inside of the forging machine body 100, achieving a double beneficial effect.

[0069] At the same time, the first air flow A plays a leading role in the flow direction of the mixed hot air flow D, blocking the diffusion of the forging hot gas B to the worker operation area 001, and ensuring the temperature safety of the worker operation area 001. A triple beneficial effect is achieved.

[0070] According to the method for using an aluminum alloy forging device according to the second aspect embodiment of the present invention, this method is based on the above-mentioned method for using an aluminum alloy forging device. It includes the following steps:

[0071] Step 1, heat the forging and place it on the forging platform 140, open the front open port 150 (in front of the front open port is the worker operation area 001, where workers operate the forklift to flip and observe the forging), close the other three open ports 150, and drive the forging hammer 110 to continuously forge the forging. That is to say, during the forging process, by respectively driving the heat preservation movable doors 220 on the left and right sides and the rear side of the forging machine body 100 to descend to their respective corresponding open ports 150, the open ports 150 on the left and right sides and the rear side of the forging machine body 100 are closed, thereby playing a heat preservation role for the forging during the forging process, helping to maintain the temperature of the forging within a better forging temperature range, and improving the processing efficiency and forging quality.

[0072] During the forging process in Step 1, adjust the angle of the forging through the front open port 150, and control the forging rhythm and number of times. This is to consider keeping the front open port 150 in an open state to facilitate the operation of the operator.

[0073] During the forging process in Step 1, heat the forging through the spray gun 310 to keep the temperature of the forging at 450°C - 500°C all the time. That is to say, by aligning the jet port of the spray gun 310 with the forging to apply a high-temperature heat source, the heat absorption efficiency of the forging can be improved, thereby further improving the processing efficiency.

[0074] During the forging process in Step 1, the blower 500 is always turned on, and the air flow blows out from the first flow channel 160, taking the hot air overflowing from the front open end 150 to above the front open end 150. That is to say, under the action of the blower 500, air enters the first flow channel 160 from the second flow channel 170 and is discharged above the forging platform 140 through the opening 161 on the first flow channel 160. This structure enables the hot air flow emitted by the forging to gather on the front and rear sides of the forging machine body 100, while the left and right sides of the forging machine body 100 can still be maintained at a relatively low temperature, thus facilitating the operator to work on the left and right sides of the forging machine body 100 and further improving the convenience and safety of operation.

[0075] During the forging process in Step 1, the suction port of the suction hood 610 adsorbs the gas blown out from the opening, and returns the gas to the position of the spray gun 310. That is to say, the heat overflowing from the opening 161 of the first flow channel 160 is re-adsorbed by the heat source recovery assembly 600, and a part of it returns to the inside of the forging machine body 100, realizing a certain proportion of internal circulation of the heat. At the same time, the oxygen required for the combustion of the spray gun 310 (the air from the outlet to the suction hood 610 also carries a part of the external air, and this part of the air contains oxygen) is brought back to the inside of the forging machine body 100, achieving a double beneficial effect.

[0076] The above is the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art of this technology, without departing from the principle described in the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
