Description

Technical Field

[0001] The invention relates to the field of aluminum profile processing for auto parts, and in particular to a surplus material cutting device and method for aluminum alloy die-casting for auto parts. Background Art

[0002] Many standard aluminum profiles or bars used in auto parts are directly die-formed. The aluminum bars are preheated by induction heating equipment. After being preheated to a certain temperature, they are transferred to the extrusion molding port of the mold. Under the support of the supporting arm, the aluminum bars are extruded into the molding port of the mold by hydraulic rods. The aluminum profiles discharged from the mold outlet can be made into standard aluminum profiles for auto parts of different shapes according to the shape of the mold. After the extrusion molding is completed, they are cooled, segmented again, and quenched and hardened.

[0003] When the preheated aluminum rod is supported by the supporting arm and swung to place it at the molding entrance of the mold, in order to ensure that no molding cavity (or gap) will be generated between the subsequently pushed aluminum rod and the aluminum rod that entered the mold previously, the hydraulic rod will not push the aluminum rod completely into the mold, but will leave one end at the feed port of the mold. After the extrusion molding is completed, the remaining part will be cut off to ensure that no gap will be generated between the subsequently pushed aluminum rod and the aluminum rod that was first fed into the mold, thereby ensuring the consistency of the strength of the aluminum profile extrusion molding.

[0004] The remaining part of the aluminum bar is cut off by configuring a die-cutting mechanism above the mold feed port, and the die-cutting knife moves downward in line with the mold feed port to cut off the remaining material. During the cutting process, since the aluminum bar is in a heated state, the overall texture is relatively soft. When it is cut and falls into the residual hopper, the residual material will contact the mold feed port, the side of the mold, and the inner wall of the residual hopper. There is a part of the material that is easy to adhere to three positions (especially in the residual hopper. Because the residual hopper is between the hydraulic mechanism and the mold mechanism, it is difficult to clean the inside of the residual hopper. Usually, the aluminum that falls into the residual hopper is allowed to automatically roll down the row, which causes the inner wall of the residual hopper to be rough and easily adhere to the heated aluminum plate residual material). If the adhered part of the aluminum is not cleaned manually in time, it will accumulate more and more, thereby affecting the normal discharge and recovery of the aluminum in the residual hopper. In addition, the temperature at the location of the residual hopper is relatively high, making it even more difficult to clean manually. Summary of the invention

[0044] A method for removing excess material from an aluminum alloy die-casting device for automotive parts, the method comprising the following steps:

[0045] S1, excess material removal: drive the concave arc frame 3 to move upward as a whole, use the cutter 9 fitted with the feed inlet 2 to remove the excess material of the aluminum rod, and separate the excess material of the aluminum rod from the forming mold 1;

[0046] S2, jet-assisted unloading: When the heated and flexible aluminum rod residue is sliding down along the inclined surface of the cutter 9, the air blowing component is triggered by the transmission assembly, and a high-pressure air flow is ejected through the hook-shaped air groove 12, which cools down the flexible aluminum rod residue and reduces the contact area between the aluminum rod residue and the inclined surface of the cutter 9, so that the aluminum rod residue moves quickly to the stainless steel skin 8;

[0047] S3, conveying and unloading: the stainless steel skin 8 carries the aluminum bar residue and is transported in the direction away from the forming mold 1. When the aluminum bar residue approaches the tail end of the concave arc frame 3, the loosening unit is triggered by the touching component and the knocking component, so that the aluminum bar residue is frequently impacted on the surface of the stainless steel skin 8, so that the aluminum bar residue adhering to the stainless steel skin 8 is loosened in advance, so as to facilitate direct discharge.

[0048] Working principle: Each time the residual material at the feed inlet 2 is cut off, the concave arc frame 3 is driven to move up and down by the lifting structure in the prior art. During the up and down movement, the side wall of the cutter 9 is in close contact with the end of the feed inlet 2, that is, the residual material can be cut off when it moves upward. Since the residual material is in a heated state, the residual material will be deformed and piled up during the cutting process. For this purpose, the drive motor 10 is started, and the drive motor 10 drives the rotating shaft 5, so that the entire conveyor toothed belt 7 and the stainless steel skin 8 can be attached. Figure 1 The arrangement mode in the embodiment is used for clockwise transmission, and when the rotating shaft 5 is in operation, the meshing of the first gear 23 with the second tooth groove 26, and the meshing of the second gear 24 with the first tooth groove 25, can make the rotating wheel 17 rotate between the multiple edge protection buckles 18, and during the rotation process, the two optical axes 16 can be alternately pushed and pulled by the two connecting arms 19, that is, the two piston blocks 15 inside the two sealing cylinders 14 move synchronously in the opposite direction, which can ensure that the rotating wheel 17 can continuously inject pressurized gas into the through groove 11 during the rotation process, and spray it out through the hook-shaped gas groove 12 with a smaller aperture;

[0049] Since the cut-off residue will first accumulate on the inclined surface of the cutter 9, and the high-pressure airflow is ejected through the hook-shaped air groove 12, the residue covering the inclined surface of the cutter 9 can be quickly dropped onto the stainless steel skin layer 8, and the residue is moved away from the forming mold 1 through the conveyor toothed belt 7 covered with the stainless steel skin layer 8, and a collection box can be placed at the end of the concave arc frame 3 away from the forming mold 1 to collect the residue.

[0050] The above-mentioned collection of the aluminum rod residue is to transfer the residue from between the hydraulic rod and the forming mold 1, so as to facilitate the collection and processing of the residue, and also prevent the residue from randomly adhering when falling.

[0051] Example 2: Please refer to Figure 8 and Fig. 9 This embodiment is a further explanation of the first embodiment. The loosening unit includes a column 29 vertically arranged inside the cavity 4. The column 29 is located at one end of the cavity 4 away from the forming mold 1, and the column 29 is fixedly connected to the cavity 4. The outer surface of the column 29 is slidably sleeved with a right-angle tooth plate 28, and a spring 30 is fixedly arranged between the upper part of the right-angle tooth plate 28 and the cavity 4. The inner bottom surface of the cavity 4 is slidably assembled with a limit plate 32, and the limit plate 32 is located on the side of the column 29 close to the forming mold 1. A push rod 31 is hingedly arranged between an end surface of the limit plate 32 close to the column 29 and the outer surface of the right-angle tooth plate 28. A knocking component is arranged inside the limit plate 32, and a touch component is arranged between the right-angle tooth plate 28 and the rotating shaft 5. The touch component can touch the limit plate 32 to move back and forth.

[0052] The striking component includes several groups of beveled edges 37 and straight edges 38 opened inside the limit plate 32, the lower end edge of the beveled edge 37 is butted against the straight edge 38, a round bottom column 34 is placed on the surface of the beveled edge 37, and a limit frame 33 is mounted on the outer surface of the round bottom column 34, the limit frame 33 is fixed to the cavity 4, and the round bottom column 34 is axially slidably inserted into the inside of the limit frame 33, a plurality of touch rods 36 are fixedly provided on the top of the round bottom column 34 through an extension plate 35, and a through hole 39 movably engaged with the touch rod 36 is opened on the top of the cavity 4, when the touch rod 36 impacts upward through the through hole 39, it can hit the conveyor belt 7, and the top of the touch rod 36 will not get stuck with the rack of the conveyor belt 7.

[0053] The triggering component includes a toothless gear 27. The transmission gear roller 6 located at the end of the concave arc frame 3 away from the forming mold 1 is segmented, and the toothless gear 27 is located in the segmented shape of the transmission gear roller 6. The toothless gear 27 is also fixedly mounted on the outside of the rotating shaft 5. The toothless gear 27 is movably engaged with the vertical tooth portion of the right-angle tooth plate 28. There is a gap between the lower end surface of the right-angle tooth plate 28 and the internal bottom surface of the cavity 4. When the transmission gear roller 6 rotates to transfer the excess material by the conveyor toothed belt 7 and the stainless steel cortex 8, the toothless gear 27 can move the right-angle tooth plate 28 upward.

[0054] In this embodiment: when the aluminum bar residue falls to the upper end surface of the stainless steel skin 8, since the aluminum bar residue has not been cooled and shaped, during the transportation process, the residue will gradually adhere to the surface of the stainless steel skin 8 under the action of its own gravity, and the adhesion is tight. In order to ensure that the residue can fall quickly from the tail of the stainless steel skin 8, in this solution, the toothless gear 27 follows the rotation of the rotating shaft 5, and can intermittently move the right-angle tooth plate 28 upward and then release it. Due to the action of the spring 30, the right-angle tooth plate 28 is quickly elastically reset at the moment of release;

[0055] That is, when the right-angle tooth plate 28 moves upward, the limit plate 32 is pushed by the push rod 31, so that the bottom of the round bottom column 34 can slide on the bevel portion 37 toward the straight edge portion 38. When the right-angle tooth plate 28 is quickly reset under the action of the spring 30, the limit plate 32 can be pulled by the push rod 31, so that the limit plate 32 is quickly reset. At this time, the round bottom column 34 and the extension plate 35 are quickly lifted up by the bevel portion 37, and the touch rod 36 is allowed to pass through the through hole 39 to knock the conveyor toothed belt 7. Through frequent reciprocating knocking, the residual material on the surface of the stainless steel cortex 8 will be frequently knocked when it is close to the tail of the concave arc frame 3, so that the residual material attached to the stainless steel cortex 8 is loosened, thereby ensuring the smoothness of the residual material falling.

[0056] Example 3: Please refer to Figure 10-12This embodiment is a further explanation of the first embodiment. An auxiliary unloading unit is further provided at the bottom of the end of the concave arc frame 3 away from the forming mold 1. The auxiliary unloading unit includes a hollow box body 40 located below the concave arc frame 3, and connecting rods 41 are fixedly provided at both ends of the hollow box body 40. The end of the connecting rod 41 away from the hollow box body 40 is elastically rotatably assembled with the concave arc frame 3 through a coil spring / torsion spring. A piston disk 42 is slidably mounted inside the hollow box body 40, and a plurality of dome levers 43 equidistantly distributed in a straight line are fixedly provided at the end of the hollow box body 40 away from the connecting rod 41. The dome lever 43 is connected to the hollow box body 40, and a one-way liquid valve is provided at the joint between the hollow box body 40 and the dome lever 43. An extension sleeve 44 is fixedly connected to one end of the hollow box body 40 away from the dome lever 43, and a counterweight ball 45 is placed inside the extension sleeve 44. The hollow box body 40 and the dome lever 43 are placed at an angle, and the dome lever 43 is tangent to the end of the stainless steel skin 8 away from the forming mold 1. A plurality of liquid outlets 46 are provided on the end surface of the dome lever 43, and the liquid outlets 46 are distributed on the side of the dome lever 43 facing the stainless steel skin 8. Lubricating liquid, such as lubricating oil or water, is injected into the interior of the hollow box body 40, and a one-way liquid valve restricts the liquid inside the hollow box body 40 to flow only into the interior of the dome lever 43. A liquid injection port is provided on the outside of the hollow box body 40, and the liquid injection port is closed by a detachable piston.

[0057] In this embodiment: when the residual material adheres to the surface of the stainless steel skin layer 8 and cannot fall smoothly, the residual material follows the transmission of the stainless steel skin layer 8 and touches the dome lever 43. Through the pushing of the residual material on the dome lever 43 and the gravity of the residual material itself, the dome lever 43 and the hollow box body 40 will elastically swing clockwise. The separation of the dome lever 43 and the stainless steel skin layer 8 during the swinging process can also separate the residual material from the stainless steel skin layer 8, and when swinging downward, it falls into the collection box body by its own gravity. After the dome lever 43 is separated from the residual material, it is elastically reset again with the hollow box body 40 under the action of the coil spring / torsion spring;

[0058] Each time the hollow box body 40 and the dome lever 43 swing downward, the weighted ball 45 can roll inside the extension sleeve 44. The surface of the extension sleeve 44 has many pores. The weighted ball 45 rolls and falls onto the piston disk 42, which can slightly push the piston disk 42, so that the lubricating fluid inside the hollow box body 40 enters the liquid outlet 46 of each dome lever 43, and the lubricating fluid flows out from the liquid outlet 46. After the dome lever 43 is reset, the lubricating fluid can be distributed more evenly on the surface of each dome lever 43 by self-flow. When the dome lever 43 contacts the residual material next time, it can further ensure that the surface of the dome lever 43 will not adhere to the residual material, so that the residual material can fall directly.

[0059] The connection port between the extension sleeve 44 and the hollow box body 40 is funnel-shaped, so that the counterweight ball 45 can automatically roll into the extension sleeve 44 after the hollow box body 40 is automatically reset.
