Description

Technical Field

[0001] The invention relates to the technical field of forming dies, in particular to a forming die of a high-speed forging machine. Background Art

[0002] The existing high-speed forging equipment's forming die can only be used on one side. One side is processed according to the product's forming shape and size, while the other side's end face is processed with a 3mm deep pit. The pit surface also needs to be processed 12 times. The 10mm deep spring hole is used to install a spring to allow the supported KO sleeve to rebound after being ejected.

[0003] Due to this structure, the other side of the forming die cannot be used as a forming surface, which not only limits the utilization rate of a single forming die, but also makes the mold processing more complicated, the processing time is long, the cost is high, and when the product is demoulded, the efficiency of ejection by the KO sleeve is low and the effect is poor. Summary of the Invention

[0004] The present invention aims to solve the technical problems existing in the prior art and provides a forming die for a high-speed forging machine to solve the problem that the existing forming die can only be used on one side and one side cannot be used as a forming surface, which not only limits the utilization rate of the single forming die, but also makes the mold processing more complicated, the processing time is long, the cost is high, and in addition, when the product is demoulded, the efficiency is low and the effect is poor when it is ejected by the KO sleeve.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a forming die of a high-speed forging machine, comprising a front die, a rear die and a KO sleeve, the rear die comprising two symmetrically arranged forming cavities, and the side wall of the KO sleeve is provided with a cooling mechanism for cooling the product, and the side wall of the KO sleeve is provided with a knocking mechanism for knocking and vibrating the rear die and the front die.

[0006] The beneficial effects of the present invention are:

[0007] 1. After the forming of the high-speed forging machine is completed, the product is ejected outward from the KO sleeve into the robot arm and transferred to the next station. Since the outer diameter of the large end of the KO sleeve is larger than the size of the forming cavity of the rear die, it can be blocked by the end face of the rear die during ejection. Therefore, even if the rear die is formed on both sides, it will not affect the ejection of the product. Under the premise of not affecting the forming and ejection of the product, it can solve the problem that the rear die can only be used on one side and reduce the processing cost of the mold.

[0008] 2. The forming die of the high-speed forging machine is provided with a knocking mechanism, etc. When the KO sleeve ejects the product out, the KO sleeve moves upward and drives the second movable plate and the triangular block to move upward synchronously through the connecting plate, so that the limiting surface is against the side wall of the fixed block, thereby pushing the ring and the rotating shaft to rotate, and the rotation of the rotating shaft drives the rotation of the disc. When the protrusion is against the side wall of the first movable plate, the first movable plate and the knocking rod are pushed to move. At the same time, the first spring is compressed. When the protrusion passes over the side wall of the first movable plate, the first movable plate and the knocking rod can move and reset under the action of the first spring, so that the first movable plate and the knocking rod can move and reset under the action of the first spring, so that the knocking rod can knock and vibrate the side walls of the rear die and the front die back and forth, thereby making the product demoulding efficiency higher and the effect better.

[0009] On the basis of the above technical solution, the present invention can also be improved as follows.

[0010] Furthermore, the cooling mechanism includes a plurality of water inlet holes arranged in an array at the bottom of the KO sleeve, and a plurality of water outlet holes arranged in an array are opened on the side wall of the KO sleeve.

[0011] The beneficial effect of adopting the above further solution is that after the molding is completed, cooling water is introduced through the water inlet hole and discharged through the water outlet hole, thereby improving the cooling efficiency and effect of the product.

[0012] Furthermore, the knocking mechanism includes a mounting plate, and the upper side wall of the mounting plate is provided with two symmetrically arranged mounting grooves. The upper side wall of the mounting plate is connected to a first movable plate through a reset mechanism, and the side wall of the first movable plate is fixedly connected to two symmetrically arranged knocking rods. The movement of the first movable plate is driven by a pushing mechanism.

[0013] The beneficial effect of adopting the above-mentioned further scheme is that when the KO sleeve pushes the product out, the first movable plate and the knocking rod are pushed back and forth by the pushing mechanism, so that the knocking rod knocks and vibrates the side walls of the rear die and the front die back and forth, thereby making the product demolding efficiency higher and the effect better.

[0014] Furthermore, the reset mechanism includes a support plate fixedly connected to the side wall of the mounting plate, and the side wall of the support plate is fixedly connected to two symmetrically arranged T-shaped guide rods, the T-shaped guide rods are inserted into the side wall of the first movable plate, and the side wall of the T-shaped guide rod is sleeved with a first spring.

[0015] The beneficial effect of adopting the above further solution is that it guides and resets the movement of the first movable plate.

[0016] Furthermore, the pushing mechanism includes a fixing plate fixedly connected to the side wall of the mounting plate, and the side wall of the fixing plate is rotatably connected to the disc via a rotating shaft.

[0017] Furthermore, a plurality of protrusions arranged in an array are fixedly connected to the side wall of the disc, and the rotation of the rotating shaft is driven by a driving mechanism.

[0018] The beneficial effect of adopting the above further solution is that the rotating shaft is driven to rotate by the driving mechanism, and the rotation of the rotating shaft drives the rotation of the disc. When the protrusion abuts against the side wall of the first movable plate, the first movable plate and the knocking rod are pushed to move.

[0019] Furthermore, the driving mechanism includes a circular ring fixedly sleeved on the side wall of the rotating shaft, and the side wall of the circular ring is fixedly connected to a plurality of fixed blocks arranged in a U array, the side wall of the KO sleeve is fixedly connected to a connecting plate, and the upper side wall of the connecting plate is fixedly connected to a second movable plate, and the side wall of the second movable plate is connected to a plurality of triangular blocks arranged in an array through a telescopic mechanism, and the triangular blocks include an inclined surface and a limiting surface.

[0020] The beneficial effect of adopting the above further solution is that the KO sleeve moves upward and drives the second movable plate and the triangular block to move upward synchronously through the connecting plate, so that the limit surface abuts against the side wall of the fixed block, thereby driving the ring and the rotating shaft to rotate.

[0021] Furthermore, the telescopic mechanism includes a sliding groove provided on the side wall of the second movable plate, and a sliding plate is slidably connected in the sliding groove via a second spring, and the triangular block is fixedly connected to the side wall of the sliding plate.

[0033] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0034] The existing high-speed forging equipment's forming die can only be used on one side. One side is processed according to the product's forming shape and size, while the other side's end face is processed with a 3mm deep pit. The pit surface also needs to be processed 12 times. The 10mm deep spring hole is used to install a spring to allow the supported KO sleeve to rebound after being ejected.

[0035] After an in-depth investigation and study of the use process of the forming die, the inventors found that: due to this structure, the other side of the forming die cannot be used as a forming surface, which not only limits the utilization rate of a single forming die, but also makes the mold processing more complicated, the processing time is long, the cost is high, and when the product is demolded, the efficiency of ejection by the KO sleeve is low and the effect is poor.

[0036] The above-mentioned problem has not been publicly reported in the art. The inventor discovered the above-mentioned problem and designed the present technical solution.

[0037] The present invention provides the following preferred embodiments

[0038] like Figures 1-8As shown, a forming die of a high-speed forging machine includes a front die 9, a rear die 7 and a KO sleeve 8. The rear die 7 includes two symmetrically arranged forming cavities 701, and the side wall of the KO sleeve 8 is provided with a cooling mechanism for cooling the product 1. The side wall of the KO sleeve 8 is provided with a knocking mechanism for knocking and vibrating the rear die 7 and the front die 9. Since the outer diameter of the large end of the KO sleeve 8 is larger than the forming cavity size of the rear die 7, it can be blocked by the end face of the rear die 7 during ejection, so that even if the rear die 7 is double-sided formed, it will not affect the ejection of the product 1.

[0039] In this embodiment, Figure 2 and Figure 3 As shown, the cooling mechanism includes a plurality of water inlet holes 801 arranged in an array at the bottom of the KO sleeve 8, and a plurality of water outlet holes 802 arranged in an array are opened on the side wall of the KO sleeve 8. After the molding is completed, cooling water is introduced through the water inlet holes 801 and discharged through the water outlet holes 802 for water cooling of the molding mold.

[0040] In this embodiment, Figures 5-8 As shown, the knocking mechanism includes a mounting plate 201, and the upper side wall of the mounting plate 201 is provided with two symmetrically arranged mounting grooves 202, the upper side wall of the mounting plate 201 is connected to a first movable plate 203 through a reset mechanism, and the side wall of the first movable plate 203 is fixedly connected to two symmetrically arranged knocking rods 204, the movement of the first movable plate 203 is driven by a pushing mechanism, when the KO sleeve 8 pushes the product 1 out, the first movable plate 203 and the knocking rod 204 are pushed back and forth by the pushing mechanism, so that the knocking rod 204 knocks and vibrates the side walls of the rear die 7 and the front die 9 back and forth, thereby making the demolding efficiency of the product 1 higher and the effect better.

[0041] In this embodiment, Figure 6 As shown, the reset mechanism includes a support plate 301 fixedly connected to the upper side wall of the mounting plate 201, and the side wall of the support plate 301 is fixedly connected to two symmetrically arranged T-shaped guide rods 302, the T-shaped guide rods 302 are inserted into the side wall of the first movable plate 203, and the side wall of the T-shaped guide rod 302 is sleeved with a first spring 303, which guides and resets the movement of the first movable plate 203.

[0042] In this embodiment, Figure 6 and Figure 7As shown, the pushing mechanism includes a fixed plate 401 fixedly connected to the side wall of the mounting plate 201, and the side wall of the fixed plate 401 is rotatably connected to a disc 403 through a rotating shaft 402, and the side wall of the disc 403 is fixedly connected to a plurality of protrusions 404 arranged in an array, and the rotation of the rotating shaft 402 is driven by a driving mechanism, and the rotating shaft 402 is driven to rotate by the driving mechanism, and the rotation of the rotating shaft 402 drives the rotation of the disc 403. When the protrusion 404 abuts against the side wall of the first movable plate 203, the first movable plate 203 and the knocking rod 204 are pushed to move, and the driving mechanism includes a ring 501 fixedly sleeved on the side wall of the rotating shaft 402, and the side wall of the ring 501 is fixedly connected to a plurality of fixed blocks 502 arranged in an array, and the side wall of the KO sleeve 8 is fixedly connected to a connecting plate 503, and the connecting plate 503 is connected to the side wall of the KO sleeve 8. The upper side wall of the connecting plate 503 is fixedly connected to the second movable plate 504, and the side wall of the second movable plate 504 is connected to a plurality of triangular blocks 505 arranged in an array through a telescopic mechanism, and the triangular block 505 includes an inclined surface 506 and a limiting surface 507. The KO sleeve 8 moves upward and drives the second movable plate 504 and the triangular block 505 to move upward synchronously through the connecting plate 503, so that the limiting surface 507 is against the side wall of the fixed block 502, thereby pushing the ring 501 and the rotating shaft 402 to rotate. When the KO sleeve 8 moves downward, it drives the second movable plate 504 and the triangular block 505 to move downward synchronously. At this time, the inclined surface 506 is against the side wall of the fixed block 502, thereby pushing the triangular block 505 to retract into the sliding groove 601. At this time, the ring 501 and the rotating shaft 402 do not rotate, and no knocking operation is performed.

[0043] In this embodiment, Figure 8 As shown, the telescopic mechanism includes a sliding groove 601 opened on the side wall of the second movable plate 504, and a sliding plate 603 is slidably connected to the sliding groove 601 through a second spring 602. The triangular block 505 is fixedly connected to the side wall of the sliding plate 603, which guides and resets the movement of the sliding plate 603.

[0044] The specific working process of the present invention is as follows:

[0045] First, after the molding is completed, the product 1 is ejected outward by the KO sleeve 8 into the robot 10 and transferred to the next station. Since the outer diameter of the large end of the KO sleeve 8 is larger than the size of the molding cavity 701 of the rear die 7, it can be blocked by the end surface of the rear die 7 during ejection. Even if the rear die 7 is double-sided molding, it will not affect the ejection of the product 1. Under the premise of not affecting the molding and ejection of the product 1, it can solve the problem that the rear die 7 can only be used on one side and reduce the processing cost of the mold.

[0046] When the KO sleeve 8 pushes the product 1 out, the KO sleeve 8 moves upward and drives the second movable plate 504 and the triangular block 505 to move upward synchronously through the connecting plate 503, so that the limiting surface 507 abuts against the side wall of the fixed block 502, thereby driving the ring 501 and the rotating shaft 402 to rotate. The rotation of the rotating shaft 402 drives the rotation of the disc 403. When the protrusion 404 abuts against the side wall of the first movable plate 203, it drives the first movable plate 203 and the knocking rod 204 to move. At the same time, the first spring 303 is compressed. When the protrusion 404 passes over the side wall of the first movable plate 203, the first movable plate 203 and the knocking rod 204 can move and reset under the action of the first spring 303, so that the first movable plate 203 and the knocking rod 204 can move and reset under the action of the first spring 303, so that the knocking rod 204 can reciprocately knock and vibrate the side walls of the rear die 7 and the front die 9, thereby making the demolding efficiency of the product 1 higher and the effect better.

[0047] To sum up: the beneficial effect of the present invention is specifically reflected in that the double-sided forming rear die 7 can be used as a forming surface, which can solve the problem that the rear die 7 can only be used on one side without affecting the forming and ejection of the product 1, and also reduce the processing cost of the mold. Moreover, when the product 1 is ejected, the side walls of the rear die 7 and the front die 9 are automatically reciprocated and vibrated, thereby making the demolding efficiency of the product 1 higher and the effect better.
