Description

Technical Field

[0001] The invention relates to the technical field of automobile component manufacturing, in particular to a finished product ejecting mechanism for forging automobile components. Background Art

[0002] The manufacturing of automotive parts usually adopts the forging process. After the raw materials are heated, they are placed in the rough die, fine die and blanking die in sequence, and are forged and impacted rapidly to form the blank.

[0003] First, the raw material is heated to a red-hot state and then placed in a rough die. Through forging and impact, the blank is deformed into a rough material with the contour of the component. The rough material is then returned to the furnace for heating and placed in a fine die. It is forged and impacted again to form a fine material identical to the finished component. In order to ensure sufficient deformation during forging and impact, the raw material is usually reserved for residual material, so there will be overflow flash after forming. The fine material is then placed on the blanking die, and the flash is removed by blanking to form the finished product.

[0004] However, in the prior art, the temperature of the finished product is still high after punching, and a lifting device such as a robotic arm is required to pick up the material and then place it on a conveyor belt to be transported to a cooling position. Therefore, the reasons that limit the efficiency of the finished product forming are: 1. Unloading after punching; 2. Cooling time;

[0005] During the entire finished product discharge process, due to the high temperature of the workpiece, the high temperature of the blanking die will make it difficult to continue using the die, and the flash will fall on the die, affecting subsequent blanking, and the station conversion efficiency is poor, thus reducing the forming efficiency.

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1 to 11 , the present invention provides a technical solution:

[0035] A finished product ejection mechanism for forging automobile parts comprises a blanking frame 1, the blanking frame 1 is provided with a die plate 4 for placing a forged workpiece, the upper end of the blanking frame 1 is lifted and mounted with a blanking knife 8 facing the die plate 4, the die plate 4 is lifted and rotatably mounted on the blanking frame 1, the lower end of the blanking frame 1 is provided with a supporting column 5 located at the lower end of the die plate 4, the blanking frame 1 is provided with a first lifting rod 3, the upper end of the first lifting rod 3 is provided with a lifting block 7, one side of the lifting block 7 is provided with a motor 6, the output shaft of the motor 6 passes through the lifting block 7 and is fixedly connected to one side of the die plate 4; the upper end of the blanking frame 1 is provided with a second lifting rod 9, the blanking knife 8 is fixed to the telescopic end of the second lifting rod 9, a stepped die groove 17 is penetrated through the die plate 4, a flash groove is provided on the outer side of the upper end port of the die groove 17, and the lower end of the blanking knife 8 faces the flash groove.

[0036] Before punching, the die plate 4 is supported by the support column 5, the workpiece is placed in the die groove 17, and the flash on the workpiece is supported on the flash groove. The purpose of cutting off the flash is achieved by descending the punching knife 8.

[0037] A conveyor belt 2 is provided on one side of the punching frame 1, and a plurality of telescopically mounted ejection components are provided on the conveyor belt 2. The ejection components include a telescopic rod 12 and a clamping frame 10. One end of the clamping frame 10 is rotatably mounted on the telescopic rod 12. A plug plate 16 and a support group 15 are provided parallel to the side of the clamping frame 10 close to the punching frame 1.

[0038] By plugging in the telescopic rod 12 , the plug plate 16 and the backing plate group 15 are respectively plugged and slid against the lower and upper end surfaces of the mold plate 4 .

[0039] The insert plate 16 is fixed on the side wall of the clamping frame 10, and the supporting flange group 15 is composed of multiple groups of hollow tubes distributed at intervals. A pair of exhaust nozzles 28 that are distributed at intervals and protrude upward are provided on the side of the hollow tube close to the mold plate 4, and the other side of the supporting flange group 15 is connected to the manifold 29. A crossbeam 35 that is slidably installed inside the clamping frame 10 is provided on one side of the manifold 29. The crossbeam 35 is lifted and lowered by a third lifting rod 14 provided inside the clamping frame 10. A fan 34 connected to the manifold 29 is provided on the outside of the clamping frame 10.

[0040] The flipping is achieved by the motor 6, and the third lifting rod 14 drives the backing rail group 15 to descend, and then the workpiece falls on the backing rail group 15 under the action of gravity and is separated from the mold plate 4. With the reset of the telescopic rod 12, the purpose of lifting the workpiece is achieved. During the flipping and lifting process, the fan 34 continuously takes in air to achieve the purpose of continuously cooling the backing rail group 15 and achieving rapid cooling of the workpiece. After flipping, due to gravity, large pieces of burrs fall directly. After the backing rail group 15 descends, the exhaust nozzle 28 impacts the mold groove 17 to clean the adhered impurities and achieve the purpose of rapid air cooling of the mold plate 4.

[0041] Working principle: First, the first lifting rod 3 drives the mold plate 4 to descend to the upper end of the support column 5, and the support column 5 is used to increase the supporting strength of the mold plate 4 so that it can withstand the downward pressure and cutting impact of the punching knife 8. The second lifting rod 9 is used to drive the punching knife 8 to descend to achieve the purpose of cutting the side edge of the workpiece. (For example, Figure 5 shown);

[0042] After punching, the punching knife 8 rises and resets, and the mold plate 4 rises and separates from the support column 5 under the drive of the first lifting rod 3, so as to facilitate subsequent flipping, and rises until the lower end surface of the mold plate 4 is flush with the upper end surface of the insert plate 16 (such as Figure 6 shown);

[0043] By extending the telescopic rod 12, the inserting plate 16 and the backing plate group 15 are respectively inserted and slid against the lower and upper end surfaces of the mold plate 4 (as shown in FIG. Figure 7 shown);

[0044] The motor 6 drives the mold plate 4 to flip, driving the clamping frame 10 to flip synchronously. At this time, the insert plate 16 is on the top and the supporting olive group 15 is on the bottom. Figure 8 shown);

[0045] Then the third lifting rod 14 drives the backing plate group 15 to descend, so that the workpiece descends with the backing plate group 15 under the action of gravity and separates from the mold plate 4. Figure 10 As shown), during this process, due to gravity, large pieces of flash fall directly. After the support group 15 drops, the exhaust nozzle 28 impacts the mold groove 17, thereby cleaning the flash of the adhering impurity particles and achieving the purpose of rapid air cooling of the mold plate 4.

[0046] Finally, the telescopic rod 12 is reset and retracted, driving the insert plate 16 and the lining olive group 15 to separate from the blanking frame 1, and moving with the conveyor belt 2 to form a continuous finished product discharge process (such as Figure 11 shown).

[0047] Example 2: On the basis of Example 1, in order to ensure that the clamping frame 10 rotates with the mold plate 4 and needs to maintain the angle after rotation to avoid deflection, a plurality of groups of fixed plates 13 distributed linearly at intervals are provided on the conveyor belt 2, and one end of the telescopic rod 12 is fixed on the fixed plate 13, and a coupling block 11 is provided between the telescopic rod 12 and the clamping frame 10. A rotating shaft 31 rotatably plugged with the coupling block 11 is provided on one side of the clamping frame 10, and the other side of the coupling block 11 is fixed to the end of the telescopic rod 12. Adsorption plates 33 offset up and down along the central axis are respectively provided on both sides of the arc outer wall of the rotating shaft 31, and a magnetic block 32 is provided on the side wall of the coupling block 11. Under the reciprocating rotation of the rotating shaft 31, the adsorption plates 33 distributed on both sides are adsorbed by the magnetic block 32 in turn.

[0048] By providing adsorption plates 33 distributed on both sides and magnetic blocks 32 distributed on one side, after the clamping frame 10 is flipped 180 degrees, one set of adsorption plates 33 will inevitably be adsorbed with the magnetic block 32 to achieve the purpose of angle limitation, and the rotation drive of the motor 6 can easily overcome the magnetic adsorption to achieve rotation.

[0049] In order to ensure that the clamping frame 10 and the mold plate 4 rotate coaxially, the height difference between the insert plate 16 and the center axis of the rotating shaft 31 is equal to the height difference between the lower end surface of the mold plate 4 and the center axis of the output shaft of the motor 6. In this way, the rotating shaft 31 is directly opposite the output shaft of the motor 6, forming coaxial rotation and avoiding dislocation caused by eccentric rotation.

[0050] Example 3: Based on Example 2, the workpiece is easily stuck in the die groove 17 due to the impact of punching, and is difficult to fall under the action of gravity.

[0051] A push rod 21 facing the mold groove 17 is provided on the insert plate 16, and the push rod 21 is elastically installed on the insert plate 16. A push ball is provided at one end of the push rod 21 close to the mold groove 17, and a counterweight 20 is provided at the other end of the push rod 21. The push rod 21 is connected to the crossbeam 35 through a pull rope 23; an outer frame 18 is provided on the insert plate 16, and an expanded through groove 19 connecting to the inner cavity of the outer frame 18 is provided on the insert plate 16. The push ball at the end of the push rod 21 passes through the expanded through groove 19, and the counterweight 20 at the other end of the push rod 21 is located in the inner cavity of the outer frame 18. The middle section of the push rod 21 is sleeved with a first spring 22, one end of the first spring 22 rests on the counterweight 20, and the other end of the first spring 22 rests on the inner wall of the outer frame 18.

[0052] By arranging the cooperation between the counterweight 20 and the first spring 22, Figure 5 、 6 , 7, In the process shown, due to gravity and the squeezing of the counterweight 20, the first spring 22 is compressed, and the top ball at the end of the push rod 21 is located inside the expanded through groove 19, so that the insert plate 16 can be smoothly fitted into the lower end surface of the mold plate 4. After flipping, due to gravity and the restoring elastic force of the first spring 22, the push rod 21 extends downward along the inside of the mold groove 17 and impacts the workpiece, so that the workpiece is smoothly demolded in the mold groove 17.

[0053] Due to the gravity insertion of the push rod 21, the push rod 21 is inserted into the mold groove 17, so that the insert plate 16 cannot be separated laterally. In order to separate the insert plate 16 from the mold plate 4, an extension block 30 is provided at the upper end of the outer frame 18, and a through inner groove 25 is provided on the extension block 30 to connect to the inner cavity of the outer frame 18. One end of the pull rope 23 extends into the outer frame 18 along the through inner groove 25 and is tied to the counterweight block 20. The other end of the pull rope 23 passes through the clamping frame 10 and is fixed on the beam 35. Guide wheels 24 are provided on the clamping frame 10 and the extension block 30. The middle section of the pull rope 23 extends smoothly along the guide wheel 24.

[0054] By setting a pull rope 23, the push rod 21 and the crossbeam 35 are linked. When the support frame group 15 is lowered, the pull rope 23 is pulled to drive the push rod 21 to rise and separate from the mold groove 17, thereby facilitating the lateral separation of the insert plate 16.

[0055] A pull rod 27 is inserted into one side of the extension block 30, and one end of the pull rod 27 extends into the inner groove 25. The pull rod 27 is provided with a through hole for accommodating the pull rope 23 to extend therethrough. The other end of the pull rod 27 is located on the outside of the extension block 30, and a second spring 26 is sleeved on the pull rod 27. The two ends of the second spring 26 respectively rest on the outer wall of the extension block 30 and the end plate of the pull rod 27.

[0056] After flipping, the drawstring 23 will be pulled during the descent of the supporting rail group 15. However, before flipping, the supporting rail group 15 needs to be lowered to a height that matches the upper end surface of the mold plate 4 under the action of the third lifting rod 14. At this time, the pull rod 21 will not pull the drawstring 23 due to the gravity of the lowering. Therefore, during this process, the drawstring 23 will become loose and the drawstring 23 cannot be kept stable. Therefore, an elastic transversely arranged drawstring 27 is provided. Under the action of the second spring 26, the drawstring 23 is pulled and folded transversely to keep the drawstring 23 taut. After flipping, the drawstring 23 is straightened due to the lowering of the top rod 21 due to gravity. At this time, the second spring 26 is compressed, and the drawstring 27 slides into the inner groove 25. Figure 9 shown.

[0057] An air hole 36 is provided at the end of the crossbeam 35 . The air hole 36 is connected to the output end of the fan 34 through a foldable hose. The other end of the air hole 36 is connected to the manifold 29 .

[0058] The pipeline is connected by setting a foldable hose, and the height adjustment of the crossbeam 35 is adapted to maintain the continuous air intake of the fan 34 to the supporting column group 15.

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
