New energy automobile motor shell profile punching die

Abstract

This utility model discloses a punching die for a new energy vehicle motor housing profile, relating to the field of automotive motor housing profile processing technology. It includes a support frame with two first sliding rods fixedly connected to its inner side. A moving block is slidably connected to the inner side of each first sliding rod. The utility model uses a hydraulic cylinder to drive the lifting block downwards, causing the sliding frame on both sides or at the bottom to move downwards synchronously. Since the sliding frame and the extrusion block are rigidly or guide-connected, the downward movement of the sliding frame will synchronously push the two extrusion blocks downwards. During the insertion of the extrusion block into a preset insertion interface, a force is applied to the sliding block within the interface, causing it to overcome its original holding force and displace. This process is influenced by structural design, such as guide surfaces or linkage devices. Because the two extrusion blocks are symmetrically structured and synchronously controlled, the two sliding blocks can move simultaneously and converge towards the center, thereby clamping and positioning the intermediate profile, ensuring the consistency of the sliding block movement and the overall accuracy and reliability of the system.

Description

Technical Field

[0001] This utility model relates to the field of automotive electric motor housing profile processing technology, and in particular to a punching die for a new energy vehicle electric motor housing profile. Background Technology

[0002] During the manufacturing process of automotive electric motor housings, punching holes is required at the mounting points. Since the motor housing needs to connect to other components such as end caps, bearing housings, and brackets, these punching holes allow for the installation of fasteners such as bolts and rivets, ensuring precise fixation of all components and preventing loosening or displacement during operation.

[0003] For example, CN210996038U discloses a punching die for the housing profile of a new energy vehicle motor, including a die body. The bottom of the die body is provided with a mating hole die bottom. Fixing screws are provided at the four corners of the mating hole die bottom. The mating hole die bottom is fixedly connected to the die body by the fixing screws. A push baffle is provided on the inner side of the die body. A first threaded post is provided at both ends of the push baffle. A nut is fitted on the first threaded post. The motor housing is provided in the middle part of the die body.

[0004] However, existing technologies have problems with the positioning of profiles not being secure enough. Especially during the punching process, the profiles are prone to shifting due to the impact force, resulting in inaccurate punching positions and affecting product quality. In addition, when adjusting the punching position, existing technologies may have poor linkage between the positioning structure and the punching components, making the adjustment process cumbersome and affecting the positioning effect after adjustment. At the same time, the movement of components may also be unstable. Utility Model Content

[0005] The purpose of this utility model is to solve the problem in the prior art that the profile is prone to displacement due to impact force, resulting in inaccurate punching position, and proposes a punching mold for the housing profile of a new energy vehicle motor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a punching mold for the housing profile of a new energy vehicle motor, including a support frame, two first sliding rods fixedly connected to the inner side of the support frame, a movable block slidably connected to the inner side of the first sliding rods, a movable frame fixedly connected to the bottom of the movable block, a punching mechanism installed at the bottom of the movable frame, and a positioning mechanism installed below the punching mechanism;

[0007] The punching mechanism includes a lifting block, with slide rails fixedly connected to both sides of the lifting block. A sliding frame is slidably connected to the surface of the slide rails. An extrusion block is fixedly connected to one end of the sliding frame, and sliding plates are fixedly connected to both sides of the top of the extrusion block.

[0008] The positioning mechanism includes a base, with sliding blocks fixedly connected to both sides of the top of the base. Two movable rods are symmetrically fixedly connected to the side walls of the sliding blocks. One end of the movable rod passes through the base, and a second spring is sleeved on the outer surface of one end of the movable rod. A second sliding rod is slidably connected to the inner side of one end of the sliding plate.

[0009] Preferably, a hydraulic cylinder is installed on the top of the lifting block, and the top of the hydraulic cylinder is fixedly connected to the center of the bottom of the moving frame.

[0010] Preferably, a cylinder is installed on the side wall of the support frame, and the output end of the cylinder is fixedly connected to the side wall of the moving block.

[0011] Preferably, the inner cavity of the lifting block is slidably connected to an installation block, a punching machine is installed at the bottom of the installation block, and two first springs are symmetrically installed at the top of the installation block.

[0012] Preferably, two telescopic rods are symmetrically fixedly connected to one side of the sliding block, and a positioning block is fixedly connected to one end of each telescopic rod.

[0013] Preferably, a third spring is sleeved on the outer surface of the telescopic rod, and an insertion interface is provided on the surface of the sliding block.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] 1. In this utility model, the lifting block is driven to move downward by a hydraulic cylinder, which drives the sliding frame on both sides or the lower part of the block to move downward synchronously. Since the sliding frame and the extrusion block are rigidly or guidedly connected, the downward movement of the sliding frame will push the two extrusion blocks downward synchronously. During the process of the extrusion block being inserted into the preset insertion interface, a force will be applied to the sliding block in the insertion interface, causing it to overcome the original holding force and move. This process is affected by the structural design, such as the guide surface or linkage device. Since the two extrusion blocks are symmetrical and synchronously controlled, the two sliding blocks can move simultaneously and move towards the center, thereby clamping and positioning the intermediate profile, ensuring the consistency of the sliding block movement and the overall accuracy and reliability of the system.

[0016] 2. In this utility model, a cylinder is used as the driving element to push the moving block and its connected moving frame forward synchronously. The moving block slides along the first slide rod, ensuring the stability of linear operation and avoiding deviation and shaking. The moving frame drives the lifting block and hydraulic cylinder to move synchronously. Through the cooperation of the slide rail and the sliding frame, the lifting mechanism can achieve stable operation during horizontal displacement, ensuring punching accuracy and efficiency. The extrusion block slides up and down in conjunction with the sliding plate. The sliding plate remains vertically stable under the guidance of the second slide rod, preventing jamming. During the positioning stage, the third spring pushes the positioning block to contact the profile. As the sliding block approaches, the spring is compressed, increasing the clamping force and enhancing positioning stability. At the moment of punching completion, the lifting block continues to press down, and the mounting block and the lifting block slide relative to each other, maintaining a short-term clamping state, improving punching quality, and reducing the impact of material rebound on accuracy.

[0022] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0024] Example 1: As Figures 1-4 As shown, this utility model provides a punching mold for the housing profile of a new energy vehicle motor, including a support frame 1. Two first sliding rods 11 are fixedly connected to the inner side of the support frame 1. A moving block 12 is slidably connected to the inner side of the first sliding rods 11. A moving frame 13 is fixedly connected to the bottom of the moving block 12. A punching mechanism 2 is installed at the bottom of the moving frame 13. A positioning mechanism 3 is installed below the punching mechanism 2.

[0025] The punching mechanism 2 includes a lifting block 26, with slide rails 25 fixedly connected to both sides of the lifting block 26, a sliding frame 24 slidably connected to the surface of the slide rails 25, an extrusion block 23 fixedly connected to one end of the sliding frame 24, and sliding plates 22 fixedly connected to both sides of the top of the extrusion block 23.

[0026] The positioning mechanism 3 includes a base 31, with sliding blocks 32 fixedly connected to both sides of the top of the base 31. Two movable rods 34 are symmetrically fixedly connected to the side walls of the sliding blocks 32. One end of the movable rod 34 passes through the base 31, and a second spring 33 is sleeved on the outer surface of one end of the movable rod 34. A second sliding rod 21 is slidably connected to the inner side of one end of the sliding plate 22.

[0027] The specific setup and function of this embodiment will be described in detail below. Driven by the hydraulic cylinder 261, the lifting block 26 can be pushed vertically downwards. During this pushing process, a transmission connection is established between the lifting block 26 and its lower structure, simultaneously driving the two sliding frames 24 located on its sides or lower part to move downwards synchronously. Since the sliding frames 24 and the pressing blocks 23 are connected by a rigid or guiding connection such as a slide rail or connecting pin, the synchronous downward movement of the sliding frames 24 will further drive the two pressing blocks 23 to move downwards synchronously.

[0028] As the two pressing blocks 23 descend, their bottom ends will precisely align and insert into the preset insertion interface 321. During insertion, the pressing blocks 23 will apply a downward or lateral force to the sliding block 32 within the insertion interface 321, depending on the structural design, such as whether it has an inclined guide surface or a linkage component. Under the action of this force, the sliding block 32 will overcome the holding force of its initial position and be forced to displace under the constraint of the guide rail or groove.

[0029] Because the two pressing blocks 23 are symmetrical in structure and synchronously controlled by the lifting block 26, they will act on the two sliding blocks 32 located in their corresponding insertion interfaces 321, thereby achieving synchronous movement of the two sliding blocks 32. This synchronous movement not only ensures the consistency of the movement of the sliding blocks 32, but also makes the two sliding blocks 32 move towards each other during the movement, thereby achieving clamping and precise positioning of the profile to be punched located between them.

[0030] Example 2: Figures 2-4As shown, a hydraulic cylinder 261 is installed on the top of the lifting block 26, and the top of the hydraulic cylinder 261 is fixedly connected to the center of the bottom of the movable frame 13. A cylinder 14 is installed on the side wall of the support frame 1, and the output end of the cylinder 14 is fixedly connected to the side wall of the movable block 12. A mounting block 28 is slidably connected to the inner cavity of the lifting block 26. A punching machine is installed at the bottom of the mounting block 28, and two first springs 27 are symmetrically installed on the top of the mounting block 28. Two telescopic rods 35 are symmetrically fixedly connected to one side of the sliding block 32, and a positioning block 36 is fixedly connected to one end of the telescopic rod 35. A third spring 37 is sleeved on the outer surface of the telescopic rod 35, and an insertion interface 321 is opened on the surface of the sliding block 32.

[0031] The overall effect of this embodiment is that the cylinder 14, as the driving element of the device, can provide linear driving force to synchronously push the moving block 12 and its fixedly connected moving frame 13. During the driving process, the moving block 12 slides smoothly along the surface of the first slide bar 11. Since the first slide bar 11 effectively guides and restricts the moving block 12, the linearity and stability of its operation are ensured during the movement, effectively avoiding deviation or shaking.

[0032] The movable frame 13 is connected to the lifting block 26 and the hydraulic cylinder 261. As the movable frame 13 moves as a whole, the lifting block 26 and the hydraulic cylinder 261 also move accordingly. During this process, the lifting block 26 forms a relative sliding engagement with the slide rail 25 and the sliding frame 24 fixed to the device structure. This ensures that even if the overall structure shifts horizontally when the punching position needs to be changed, the stability of the lifting mechanism and the synchronous lifting of the extrusion block 23 can still be guaranteed, thus not affecting the punching accuracy and efficiency.

[0033] During the lifting and lowering process, the extrusion block 23 drives the sliding plate 22 to move up and down through structural linkage. The sliding plate 22 slides vertically along the surface of the second slide rod 21 set on both sides of it. The second slide rod 21 serves as a guide mechanism, effectively constraining the movement trajectory of the sliding plate 22, ensuring its stable posture during the lifting and lowering process, and avoiding component jamming or failure due to lateral displacement.

[0034] In the initial positioning stage, the third spring 37, installed within the structure, pushes the positioning block 36 outward with its own elasticity, allowing it to make initial contact with the profile to be processed. As the two sliding blocks 32 approach each other within the guide mechanism, the compression of the third spring 37 further increases, correspondingly enhancing the clamping force acting on the profile. This significantly strengthens the stability and fixing strength of the profile positioning, providing favorable initial conditions for subsequent punching.

[0035] During the actual punching operation, the lifting block 26 does not immediately stop moving when the punching device completes the punching action. Instead, it continues to drive the pressing block 23 to apply downward pressure. At this time, relative sliding occurs between the mounting block 28 and the lifting block 26. This structural design ensures that the punching device can maintain a certain downward pressure for a short period of time after punching, effectively extending the punching holding time, ensuring punching quality, and reducing the impact of material springback on forming accuracy.

[0036] The device is used and operates as follows: Hydraulic cylinder 261 drives the lifting block 26 to move downward. During this process, the lifting block 26 drives the two sliding frames 24 to move downward synchronously, which in turn drives the pressing block 23 to move downward together. At this time, the bottom end of the pressing block 23 will insert into the insertion interface 321, exerting a force on the sliding block 32, thereby driving the sliding block 32 to move.

[0037] Therefore, when the two extrusion blocks 23 move with the lifting block 26, they will control the two sliding blocks 32 to move synchronously, so that the two blocks move closer to each other, thereby further extruding and positioning the profile to be punched, and preventing deviation during punching.

[0038] The cylinder 14 drives the movable block 12 to move together with the movable frame 13, and the movable block 12 slides on the surface of the first slide bar 11 to maintain stable movement. In addition, when the movable frame 13 drives the lifting block 26 and the hydraulic cylinder 261 to move, it will slide relative to the sliding frame 24 through the slide rail 25. In this way, when adjusting the punching position, the extrusion block 23 can still be driven to rise and fall synchronously.

[0039] At the same time, the pressing block 23 will drive the sliding plate 22 to rise and fall together, and the sliding plate 22 will maintain a stable up and down movement on the surface of the second slide bar 21.

[0040] During initial positioning, the elastic force of the third spring 37 will push the positioning block 36 to contact the profile; as the two sliding blocks 32 gradually approach each other, the applied squeezing force will further increase, thereby ensuring the firmness and stability of the positioning.

[0041] During the punching process, after the punching equipment completes the punching, the lifting block 26 can continue to drive the pressing block 23 to move downward. At this time, the mounting block 28 will slide relative to the lifting block 26 to ensure that the punching equipment has enough punching time.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
