Description

Technical Field

[0001] The invention relates to the technical field of automobile accessories, in particular to a stamping die for a tube beam of an automobile rear auxiliary frame. Background Art

[0002] In the automotive manufacturing industry, the rear subframe tube beam is an important part of the automotive chassis structure, and its quality and production efficiency are directly related to the performance and market competitiveness of the entire vehicle. Traditional stamping die design often uses a single die set for stamping operations, that is, after a die set completes stamping, it is necessary to wait for the operator to remove the stamped parts and place new workpieces to be stamped before the next stamping can be performed. This operation method is not only inefficient, but also increases the labor intensity and safety risks of the operators. Summary of the invention

[0003] In view of the problems existing in the above-mentioned background technology, the present invention patent aims to propose an innovative solution, namely, a stamping die for a tube beam of a rear subframe of an automobile.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions: a stamping die for a rear subframe tube beam of an automobile, comprising a bottom plate, a first motor, a second motor, an upper die and a lower die, wherein two fixed plates are symmetrically fixedly connected to the top of the bottom plate, the first motor is fixedly connected to the side wall of one of the fixed plates, a movable rod is arranged between the two fixed plates, the shape of the movable rod is a right-angle Z shape, both ends of the movable rod are fixedly connected to connecting rods, one of the connecting rods is fixedly connected to the driving end of the first motor, and the other connecting rod is rotatably connected to the other fixed plate, the shape of the two connecting rods are both L-shaped, the cross bar portion of the connecting rod is fixedly connected to a group of fan blades, the second motor is fixedly connected to the other fixed plate away from the movable The side wall of the movable rod, the driving end of the second motor is fixedly connected with a bidirectional screw rod, the bidirectional threads of the bidirectional screw rod are threadedly connected with a movable block, a connecting plate is arranged under the movable block, the side walls of the two connecting plates are penetrated with limiting grooves, the two cross bar parts of the movable rod are respectively slidably clamped in the two limiting grooves, the top of the connecting plate is fixedly connected with a fixing rod, the fixing rod penetrates the movable block, the bottom of the connecting plate is fixedly connected with a connecting block, the upper mold is fixedly connected to the bottom of the connecting block, the two lower molds are symmetrically fixedly connected to the top of the bottom plate, the two lower molds are both located between the two fixed plates, one of the upper molds is molded with one of the lower molds, and the other upper mold is located directly above the other lower mold.

[0005] Preferably, a limit rod is fixedly connected between the two fixed plates, the limit rod passes through the two movable blocks, and the limit rod is located directly in front of the bidirectional screw rod.

[0006] Preferably, the two upper molds are located between two groups of fan blades.

[0007] Preferably, one end of the bidirectional lead screw away from the second motor is rotatably connected to one of the fixed plates.

[0008] Preferably, the two connecting rods are centrally symmetrically arranged.

[0009] Working principle: When a stamping die for a rear subframe tube beam of an automobile is used, the die uses a second motor to drive a bidirectional screw rod, and the movement of the bidirectional screw rod drives two movable blocks to move respectively. The two movable blocks are connected to two connecting plates through a fixed rod, so when the movable block moves, the connecting plate will also move with it. This design allows the spacing between the two upper molds to be adjusted, so that two workpieces to be stamped can be placed into the corresponding lower mold at the same time. The first motor drives the driving rod, which in turn drives the movable rod to rotate in a circle. The movable rod is clamped in the limit groove on the connecting plate, so the rotation of the movable rod is converted into a linear movement of the connecting plate. The fixed rod on the connecting plate runs through the movable block to ensure that the connecting plate is limited by the trajectory of the movable block during movement. Since the movable rod is in a right-angle Z shape, when the movable rod rotates, it drives the two connecting plates to move up and down in opposite directions. This means that when one upper mold is molded with the corresponding lower mold, the other upper mold will be separated from its corresponding lower mold, which is convenient for the operator to remove the stamped workpiece. Through the control of the first motor, the two sets of upper and lower molds can be in a mold-closed and non-closed state respectively. This alternating working mode greatly improves the stamping efficiency of the mold. When one set of molds is in the mold closing state for stamping, the other set of molds is in a separated state, which is convenient for removing the stamped workpiece and placing the new workpiece to be stamped. When the first motor drives the upper mold to separate from the lower mold, the fan blades on the connecting rod will rotate. The rotating fan blades can cool the stamped workpiece in the lower mold, which helps to reduce the temperature of the workpiece and improve the removal efficiency. The cooled workpiece is easier to remove from the mold, reducing the operation time and difficulty.

[0010] The present invention provides a stamping die for a tube beam of a rear subframe of an automobile, which has the following beneficial effects: 1. The first motor and the second motor work together to achieve the alternating closing and separation of the two sets of upper and lower dies. This design not only improves the stamping efficiency, but also ensures the possibility of continuous production, so that while one set of dies is stamping, the other set of dies can prepare for the next stamping cycle, thereby significantly improving the throughput of the overall production line.

[0011] 2. The distance between the two upper molds can be easily adjusted by using the second motor to drive the bidirectional screw rod. This flexibility enables the mold to adapt to workpieces of different sizes and shapes, improving the versatility and applicability of the mold.

[0012] 3. When one upper die is combined with the corresponding lower die for stamping, the other upper die will be separated from its corresponding lower die, providing the operator with sufficient space and time to remove the stamped workpiece and place the new workpiece to be stamped. This design reduces waiting time and improves work efficiency.

[0013] 4. When the first motor drives the upper die to separate from the lower die, the fan blades on the connecting rod will rotate to cool the stamped workpiece in the lower die. This helps to reduce the temperature of the workpiece, prevent deformation or damage of the workpiece due to high temperature, and also improves the efficiency of removing the workpiece. The cooled workpiece is easier to separate from the die, reducing the difficulty and time of operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention. Example

[0017] like Figure 1-2As shown, an embodiment of the present invention provides a stamping die for a rear subframe tube beam of an automobile, comprising a bottom plate 1, a first motor 3, a second motor 7, an upper die 14 and a lower die 15. Two fixed plates 2 are symmetrically fixedly connected to the top of the bottom plate 1, the first motor 3 is fixedly connected to the side wall of one of the fixed plates 2, a movable rod 4 is arranged between the two fixed plates 2, the movable rod 4 is in a right-angle Z shape, both ends of the movable rod 4 are fixedly connected to connecting rods 5, one of the connecting rods 5 is fixedly connected to the driving end of the first motor 3, and the other connecting rod 5 is rotatably connected to the other fixed plate 2, the two connecting rods 5 are both in an L-shape, a group of fan blades 6 are fixedly connected to the crossbar portion of the connecting rod 5, the second motor 7 is fixedly connected to the side wall of the other fixed plate 2 away from the movable rod 4, the driving end of the second motor 7 The two ends are fixedly connected with a bidirectional screw rod 8, and the bidirectional threads of the bidirectional screw rod 8 are threadedly connected with a movable block 10. A connecting plate 11 is arranged below the movable block 10. The side walls of the two connecting plates 11 are penetrated with limiting grooves 16. The two cross bar parts of the movable rod 4 are slidably connected to the inside of the two limiting grooves 16 respectively. The top of the connecting plate 11 is fixedly connected with a fixing rod 12, and the fixing rod 12 penetrates the movable block 10. The bottom of the connecting plate 11 is fixedly connected with a connecting block 13. The upper mold 14 is fixedly connected to the bottom of the connecting block 13. The two lower molds 15 are symmetrically fixedly connected to the top of the bottom plate 1. The two lower molds 15 are both located between the two fixed plates 2, one of the upper molds 14 is molded with one of the lower molds 15, and the other upper mold 14 is located directly above the other lower mold 15.

[0018] The limit rod 9 passes through the two movable blocks 10 and is located in front of the bidirectional screw 8. Its main function is to ensure that the two movable blocks 10 can move stably and synchronously without deviation or tilt under the drive of the bidirectional screw 8. Through the constraint of the limit rod 9, the moving trajectory of the movable block 10 is more precise, thereby ensuring that the spacing adjustment between the upper molds 14 is more accurate and reliable.

[0019] The two upper molds 14 are located between the two sets of blades 6. This means that when the first motor 3 drives the movable rod 4 to drive the connecting plate 11 to move up and down, the blades 6 can work at the same time to cool the stamped workpiece in the lower mold 15. This design ensures the synchronization of the cooling process and the stamping process, and improves the cooling efficiency and removal efficiency of the workpiece.

[0020] One end of the bidirectional screw rod 8 away from the second motor 7 is rotatably connected to one of the fixed plates 2. This design ensures that the bidirectional screw rod 8 can stably rotate under the drive of the second motor 7 and drive the two movable blocks 10 to move in opposite directions. Through the stable rotation connection, the bidirectional screw rod 8 can efficiently transmit power and realize the precise movement of the movable block 10 and the connecting plate 11.

[0021] The two connecting rods 5 are arranged symmetrically. This design not only ensures the symmetry of the mold structure, but also enables the two fan blades 6 to be evenly distributed on both sides of the mold, achieving a more uniform cooling effect. The centrally symmetrical layout helps to balance the stress of the mold during operation and improve the stability and service life of the mold. At the same time, the uniform cooling effect also helps to improve the quality and consistency of the workpiece.

[0022] Although 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 the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
