Description

Technical Field

[0001] This invention relates to the field of forging die technology, and in particular to a hydraulically controlled rapid switching device for large forging dies and its method of use. Background Technology

[0002] A hydraulic forming machine is a device that uses hydraulic pressure to press an upper and lower mold to obtain a mold of a certain shape. It is typically used to process metal, plastic, rubber, and other products. Before hydraulic forming large forgings, different hydraulic forming machines with different molds are often selected based on the product shape or type, or different mold shapes may be replaced. In existing technology, hydraulic forming machines can be equipped with molds of different shapes.

[0003] The traditional method of changing molds involves manually loosening nuts to remove the fixed mold, pushing the old mold away from the forging table, placing the new mold on the moving platform and pushing it under the hydraulic rod, then installing it by loosening nuts. However, molds for large forgings are heavy, and manually moving them in and out is time-consuming and labor-intensive. It also requires repeated adjustments to the mounting holes to align them with the original mounting holes of the hydraulic components. This cumbersome process hinders rapid mold installation and removal, reducing forging production efficiency. Summary of the Invention

[0052] The moving groove, located at the bottom of the lifting seat, is used to guide the sliding trajectory of the moving block.

[0053] This invention also discloses a method for using a hydraulically controlled rapid switching device for large forging dies, comprising the following steps:

[0054] S1: Disassemble the original mold body, remove the bolts between the upper template and the mounting plate and the bolts between the lower template and the base, control the forging hydraulic cylinder to retract the hydraulic rod, so that the mounting plate is separated from the mold body;

[0055] S2: Rotate the support base around the rotating rod, from the initial position parallel to the side of the base to the position perpendicular to the base; activate the support hydraulic cylinder, the hydraulic rod extends and pushes the support plate to the ground, forming a stable support for the far end of the support base;

[0056] S3: The support plate moves down, causing the telescopic plate to rotate. The swing plate rotates around the pin connected to the support base. The swing plate pushes the moving block to slide in the moving groove, causing the lifting seat to move up along the support base. The lifting seat lifts the mold body through the ball bearings, causing the mold body to detach from the base surface and be in a suspended state.

[0057] S4: Start the drive motor, which drives the first lead screw to rotate in the forward direction. Through the meshing of the active bevel gear and the driven bevel gear, the transmission rod is driven to rotate.

[0058] First pushing component: The rotation of the first lead screw causes the first sleeve to move the push plate back, and the push plate no longer abuts against the side of the mold body;

[0059] Second pushing component: The transmission rod rotates, driving the second lead screw to rotate, the second sleeve moves back, the push seat engages with the pull ring through the movable block, the push seat pulls the mold body away from the base, the removed mold body slides smoothly along the ball bearings on the surface of the support seat to the external work station, and the workers use the lifting tool to remove the old mold body and place the new mold body;

[0060] S5: The drive motor rotates in the opposite direction, the first lead screw rotates in the opposite direction, and the linkage transmission rod rotates in the opposite direction.

[0061] The first sleeve of the first pushing component drives the pushing plate to move towards the base. The pushing seat of the second pushing component pushes the mold body to the upper side of the base through the L-shaped seat until the mold body abuts against the limiting plate. At this time, the pushing plates on both sides of the base have not yet completed clamping the mold body.

[0062] As the drive motor continues to run, the push plates on both sides of the base continue to move and gradually approach the side of the mold body to achieve centering and clamping of the mold body. Since the mold body is placed on the ball bearings, it is subjected to force when it comes into contact with the push plate and the placement position is easily adjusted so that the mold body is placed in the middle of the base, ensuring that the screw holes of the mold body are aligned with the screw holes of the base and the mounting plate. During this period, the elastic telescopic rod is compressed, and the movable block is subjected to force to retract into the movable groove and reset after entering the pull ring.

[0063] S6: The support hydraulic cylinder retracts the hydraulic rod, causing the lifting seat to move down. The bottom of the mold body fits against the top of the base, allowing the forging hydraulic cylinder to move out of the hydraulic rod. The upper template and mounting plate, and the lower template and base are then re-fixed with bolts. Finally, the support seat is folded back to its initial position, completing the mold switching.

[0064] Compared with the prior art, the present invention provides a hydraulically controlled rapid switching device for large forging dies and its usage method, which has the following beneficial effects:

[0065] 1. The hydraulically controlled large forging die quick switching device and its usage method, through the coordinated operation of screw drive, bevel gear linkage and elastic buffer mechanism, hydraulic drive, multi-directional pushing mechanism and lifting component, realizes the precise pushing of the die body and automatic alignment of screw holes, reduces manual intervention, solves the problems of manual dependence, positioning difficulty and low efficiency in traditional die changing, significantly shortens the die switching time and improves the continuous operation capability of large forging production line;

[0066] 2. The hydraulically controlled large forging die quick switching device and its usage method, when the drive motor is working, its output shaft drives the first lead screw to rotate, the first sleeve moves along the first lead screw axis, and the first sleeve drives the push plate to move closer to or away from the die body, thereby realizing the clamping or releasing action of the die body;

[0067] 3. The hydraulically controlled large forging die quick switching device and its usage method: When the first lead screw rotates, the linkage transmission rod rotates. When the first pushing component clamps the die body, the pushing seat of the second pushing component pushes the die body to the upper side of the base through the L-shaped seat until the die body abuts against the limiting plate. At this time, the pushing plates on both sides of the base have not yet completed clamping the die body. As the drive motor continues to run, the pushing plates on both sides of the base continue to move and gradually approach the side of the die body to achieve centering and clamping of the die body. Since the die body is placed on the ball bearings, it is subjected to force when it abuts against the pushing plate and can be easily adjusted to place the die body in the middle of the base. This ensures that the screw holes of the die body are aligned with the screw holes of the base and the mounting plate, reducing manual intervention and solving the problems of manual dependence, positioning difficulties and low efficiency in traditional die changing. It significantly shortens the die switching time and improves the continuous operation capability of the large forging production line.

[0068] 4. The hydraulically controlled large forging die quick switching device and its usage method: When the push seat is moved by the second sleeve, the movable seat abuts against the die body. The movable block on the movable seat and the pull ring retract under force and enter the movable groove. After entering the pull ring, it returns to its original position because it is no longer under pressure. When the push seat moves away from the die body, the push seat engages with the pull ring through the movable block. The push seat pulls the die body away from the base. The removed die body slides along the support seat to the external station, assisting the die to be quickly removed.

[0069] 5. The hydraulically controlled large forging die quick switching device and its usage method, when the support plate moves down, it drives the telescopic plate to rotate, and the linkage swing plate rotates around the pin shaft connected to the support base. The swing plate pushes the moving block to slide in the moving groove, so that the lifting seat moves up along the support base. The lifting seat lifts the die body through the ball bearings, so that the die body is separated from the base surface and is in a suspended state, which facilitates the smooth sliding of the pushing mechanism when pushing or pulling the die body, realizing the quick movement of the die in / out. It solves the problem of the large weight of the large die and the difficulty of manual adjustment of the position in the existing technology, ensures the die installation speed, and enables the die to be switched quickly.

[0083] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0084] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0085] like Figures 1 to 3As shown, this embodiment proposes a hydraulically controlled rapid switching device for large forging dies, belonging to the field of forging die technology. It includes a base 1, a top plate 2, a hydraulic mechanism 3, a die body 4, and a pushing mechanism 5. The top plate 2 and base 1 are arranged vertically at intervals via support columns 201, forming a rigid frame. The hydraulic mechanism 3 is mounted on the top plate 2 and drives the die body 4 to close forging. The die body 4 is configured as a detachable split structure, located between the base 1 and the hydraulic mechanism 3. The pushing mechanism 5 is symmetrically distributed on both sides of the base 1, including a first pushing component for pushing the left / right side of the die body 4, a second pushing component for pushing the front side of the die body 4, and a lifting component for lifting the die body 4. The pushing direction of the first pushing component of the pushing mechanism 5 is perpendicular to the pushing direction of the second pushing component. This application solves the problems of manual dependence, positioning difficulties, and low efficiency in traditional die changing through the coordinated operation of hydraulic drive, the multi-directional pushing mechanism 5, and the lifting component, significantly shortening die switching time and improving the continuous operation capability of large forging production lines.

[0086] like Figure 1 , Figure 3 and Figure 4 As shown, in a preferred embodiment, based on the above method, the hydraulic mechanism 3 further includes a forging hydraulic cylinder 301 fixed on the top plate 2. The forging hydraulic cylinder 301 is installed by a flange and is vertically fixed to the center of the top plate 2 by high-strength bolts. The mounting plate 302 and the end of the hydraulic rod are connected by a threaded anti-loosening structure. The mounting plate 302 and the base 1 are both provided with first screw holes for installing the mold body 4. Two forging hydraulic cylinders 301 can be used and controlled synchronously by parallel oil circuits to avoid mold misalignment when a single hydraulic cylinder drives the mold closing, or a guide rod can be set to guide the mounting plate 302.

[0087] like Figure 5 As shown, in a preferred embodiment, based on the above method, the mold body 4 further includes an upper template 401, a lower template 404, an upper mold base 402 and a lower mold base 403. The upper template 401 and the lower template 404 are both connected by bolts to the first screw hole 16 and the second screw hole 17. The upper mold base 402 is fixedly connected to the upper template 401, and the lower mold base 403 is fixedly connected to the lower template 404. After the upper mold base 402 and the lower mold base 403 are closed and connected, a forging mold cavity is formed.

[0088] like Figure 1 , Figure 3 , Figure 6 and Figure 8As shown, in a preferred embodiment, based on the above method, the first pushing component further includes a drive motor 6 fixedly mounted on the base 1. When the drive motor 6 is working, its output shaft drives the first lead screw 601 to rotate, and the first sleeve 602 moves axially along the first lead screw 601. The first sleeve 602 drives the push plate 603 to move closer to or away from the mold body 4, thereby realizing the clamping or releasing action of the mold body 4.

[0089] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, in a preferred embodiment, based on the above method, the second pushing component further includes a transmission rod 8 pivotally connected to the inner cavity of the base 1 via a bearing. When the first lead screw 601 rotates, the driving bevel gear 121 on its outer side meshes with the driven bevel gear 12 on the transmission rod 8. Since the second sleeve 10 is threadedly connected to the transmission rod 8, the second sleeve 10 is displaced axially along the transmission rod 8, causing the second sleeve 10 to drive the pushing seat 11 away from or towards the mold body 4. When the second sleeve 10 drives the pushing seat 11 towards the mold body 4, the pushing seat 11 pushes the mold body 4 until the mold body 4 abuts against the limiting plate 13 on the base 1, thus limiting the movement distance of the mold body 4.

[0090] like Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, in a preferred embodiment, based on the above method, the push seat 11 further includes a fixed seat 111 rigidly connected to the second sleeve 10. When the second sleeve 10 drives the push seat 11 to approach the mold body 4 and pushes the mold body 4, the fixed seat 111 transmits force to the movable seat 113 through the elastic telescopic rod 112, so that the movable seat 113 abuts against the mold body 4 and pushes it. When the end of the mold body 4 away from the movable seat 113 abuts against the limiting plate 13, as the second sleeve 10 drives the fixed seat 111 to continue to move, when the movable seat 113 can no longer move, the elastic telescopic rod 112 is compressed.

[0091] The specific process is as follows:

[0092] The first sleeve 602 of the first pushing component drives the push plate 603 to move towards the base 1. The push seat 11 of the second pushing component pushes the mold body 4 to the upper side of the base 1 through the movable seat 113 until the mold body 4 abuts against the limiting plate 13. At this time, the push plates 603 on both sides of the base 1 have not yet completed clamping the mold body 4.

[0093] As the drive motor 6 continues to run, the push plates 603 on both sides of the base 1 continue to move and gradually approach the side of the mold body 4, achieving centering and clamping of the mold body 4, placing the mold body 4 in the middle of the base 1, ensuring that the screw holes of the mold body 4 are aligned with the screw holes of the base 1 and the mounting plate 302. During this period, the elastic telescopic rod 112 is compressed, achieving precise pushing of the mold body 4 and automatic alignment of the screw holes, reducing manual intervention, solving the problems of manual dependence, positioning difficulties and low efficiency in traditional mold changes, significantly shortening mold changeover time, and improving the continuous operation capability of large forging production lines. It should be noted that wear-resistant surfaces or ball bearings can be set on the contact surface between the movable seat 113 and the mold body 4, so that the mold body 4 can slide smoothly relative to the movable seat 113 when pushed by the push plate 603, reducing its wear and extending its service life.

[0094] like Figure 8 , Figure 9 and Figure 12 As shown, in a preferred embodiment, based on the above method, the transmission rod 8 further includes a rotating rod 801 pivotally connected to the inner cavity of the base 1 via a bearing. The rotating rod 801 is connected to the second lead screw 802 via a universal joint. The universal joint is existing technology and will not be described in detail here. The universal joint is made of alloy steel to ensure its service life. When the rotating rod 801 rotates, it can drive the second lead screw 802 to rotate through the universal joint, thereby causing the second pushing component to move. The support base 9 is rotatably connected to the base 1 via a rotating rod 7. When changing large molds, the support base 9 moves to a position perpendicular to the base 1, which facilitates the replacement and transfer of large molds. When the large mold is used to process, store, or transfer forgings, the support base 9 rotates and moves to a position parallel to the base 1 to avoid occupying too much area and hindering the use of the staff.

[0095] like Figure 8 , Figure 9 and Figure 11 As shown, in a preferred embodiment, based on the above method, the movable seat 113 further includes an L-shaped seat 1131 fixedly connected to the elastic telescopic rod 112. The inner side of the L-shaped seat 1131 is provided with a movable groove 1132. A movable block 1133 is connected to the movable groove 1132 through an elastic element 1134. When the second sleeve 10 drives the push seat 11 to move, the movable seat 113 abuts against the mold body 4. The movable block 1133 on the movable seat 113 abuts against the pull ring 14 and retracts into the movable groove 1132. After entering the pull ring 14, it returns to its original position because it is no longer under pressure. When the push seat 11 moves away from the mold body 4, the push seat 11 engages with the pull ring 14 through the movable block 1133. The push seat 11 pulls the mold body 4 away from the base 1. The removed mold body 4 slides along the support seat 9 to the external work position. The workers use a hoist to remove the old mold body 4 and place the new mold body 4.

[0096] like Figure 6 , Figure 7 , Figure 9 and Figure 10 As shown, in a preferred embodiment, based on the above method, the lifting assembly further includes a support 15 fixedly mounted on the support base 9, on which a support hydraulic cylinder 151 is mounted. When the support hydraulic cylinder 151 is activated, the hydraulic rod extends and pushes the support plate 152 to abut against the ground, forming a stable support for the far end of the support base 9, thus fixing the position of the support base 9. When the support plate 152 moves down, it drives the telescopic plate 153 to rotate, and the swing plate 154 rotates around the pin connected to the support base 9. The swing plate 154 pushes the moving block 155 to slide in the moving groove 1562, so that the lifting seat 156 moves up along the support base 9. The lifting seat 156 lifts the mold body 4 through the ball bearings 1561, so that the mold body 4 is detached from the surface of the base 1 and is in a suspended state, which facilitates the smooth sliding of the pushing mechanism 5 when pushing or pulling the mold body 4, realizing the rapid movement of the mold in / out, solving the problem of the large weight of the large mold and the difficulty of manual adjustment of the position in the prior art, ensuring the mold installation speed, and enabling the mold to be switched quickly.

[0097] This invention also discloses a method for using a hydraulically controlled rapid switching device for large forging dies, comprising the following steps:

[0098] S1: Disassemble the original mold body 4, remove the bolts between the upper template 401 and the mounting plate 302 and the bolts between the lower template 404 and the base 1, control the forging hydraulic cylinder 301 to retract the hydraulic rod, so that the mounting plate 302 is separated from the mold body 4;

[0099] S2: Rotate the support base 9 around the rotating rod 7, and rotate the support base 9 from the initial position parallel to the side of the base 1 to the position perpendicular to the base 1; start the support hydraulic cylinder 151, the hydraulic rod extends and pushes the support plate 152 to abut against the ground, forming a stable support for the far end of the support base 9;

[0100] S3: The support plate 152 moves down, causing the telescopic plate 153 to rotate. The swing plate 154 rotates around the pin connected to the support base 9. The swing plate 154 pushes the moving block 155 to slide in the moving groove 1562, causing the lifting seat 156 to move up along the support base 9. The lifting seat 156 lifts the mold body 4 through the ball bearing 1561, so that the mold body 4 is separated from the surface of the base 1 and is in a suspended state.

[0101] S4: Start the drive motor 6, which drives the first lead screw 601 to rotate in the forward direction. Through the meshing of the active bevel gear 121 and the driven bevel gear 12, the transmission rod 8 is driven to rotate.

[0102] First pushing component: The rotation of the first lead screw 601 causes the first sleeve 602 to drive the push plate 603 to move back, and the push plate 603 no longer abuts against the side of the mold body 4;

[0103] Second pushing component: The rotation of the transmission rod 8 drives the second lead screw 802 to rotate, the second sleeve 10 moves back, the push seat 11 is engaged with the pull ring 14 through the movable block 1133, the push seat 11 pulls the mold body 4 away from the base 1, the removed mold body 4 slides smoothly along the ball bearings 1561 on the surface of the support seat 9 to the external work station, and the workers use the lifting tool to remove the old mold body 4 and place the new mold body 4;

[0104] S5: Drive motor 6 rotates in the opposite direction, first lead screw 601 rotates in the opposite direction, and linkage transmission rod 8 rotates in the opposite direction.

[0105] The first sleeve 602 of the first pushing component drives the push plate 603 to move towards the base 1. The push seat 11 of the second pushing component pushes the mold body 4 to the upper side of the base 1 through the L-shaped seat 1131 until the mold body 4 abuts against the limiting plate 13. At this time, the push plates 603 on both sides of the base 1 have not yet completed clamping the mold body 4.

[0106] As the drive motor 6 continues to run, the push plates 603 on both sides of the base 1 continue to move and gradually approach the side of the mold body 4, thereby centering and clamping the mold body 4. Since the mold body 4 is placed on the ball bearing 1561, it is subjected to force when it comes into contact with the push plate 603 and its position is easily adjusted, so that the mold body 4 is placed in the middle of the base 1, ensuring that the screw holes of the mold body 4 are aligned with the screw holes of the base 1 and the mounting plate 302. During this period, the elastic telescopic rod 112 is compressed, and the movable block 1133 is forcefully contracted into the movable groove 1132 and resets after entering the pull ring 14.

[0107] S6: The hydraulic cylinder 151 retracts its hydraulic rod, causing the lifting seat 156 to move down. The bottom of the mold body 4 fits against the top of the base 1, allowing the forging hydraulic cylinder 301 to move out of the hydraulic rod.
