Description

Technical Field

[0001] This utility model belongs to the field of electromagnetic valve housing processing technology, specifically a punching tool for processing electromagnetic valve housing. Background Technology

[0002] The air suspension damping solenoid valve is a core control component of an automotive air suspension system. It precisely controls the airflow into and out of the air springs to adjust vehicle height and suspension stiffness. The solenoid valve's housing is typically cylindrical, with one end serving as the air inlet. This end requires high-precision punching to create the supply interface for connecting the air source and the working interface for connecting the air springs. The quality and precision of the punching directly affect the solenoid valve's airtightness, connection reliability, and overall performance.

[0003] Currently, the mainstream process for punching the ends of the aforementioned cylindrical solenoid valve housing is to punch from the outside to the inside using a die. After punching, this method results in a ring of stamping burrs on the inner wall of the housing due to material tearing and deformation, making cleaning extremely difficult. To address this issue, the industry has also attempted to use an inside-out punching method, which places the burrs on the outside of the housing for easier removal. However, existing inside-out punching technology still requires a separate subsequent process to remove the outer burrs after punching, which not only prolongs the overall processing flow, increases production cycle and labor costs, but also significantly impacts the processing efficiency of the solenoid valve housing. Utility Model Content

[0004] This utility model provides a punching fixture for processing solenoid valve housings, which can solve the problems of existing technology where, after punching solenoid valve housings from the inside out, burr cleaning is required separately, the processing steps are cumbersome, and the efficiency is low.

[0005] To achieve the above objectives, according to an embodiment of the first aspect of this utility model, a punching fixture for processing the housing of a solenoid valve is provided, including a hollow processing table. Multiple support members extending into the inner cavity are embedded in the top of the processing table. A lifting assembly is installed above the support members on the top of the processing table. A stamping mechanism is installed on the lifting assembly, and the stamping mechanism is used to punch the housing body placed inside the support members. A liftable drive member is provided inside the processing table. A grinding member is installed on the drive member, located directly below the support members. The drive member is used to drive multiple grinding members to rotate synchronously. After the bottom end of the housing body is punched, the drive member drives the grinding members to rise and rotate, thereby removing the burrs generated after punching the bottom end of the housing body.

[0006] As a further technical solution of this utility model, the carrier includes a cylindrical body and an annular opening. The cylindrical body has an opening at the top, and the annular opening is located at the center of the bottom end of the cylindrical body. The diameter of the annular opening is smaller than the outer diameter of the outer shell body.

[0007] As a further technical solution of this utility model, the lifting assembly includes an I-shaped plate, guide rods, a mold handle, and a first spring. The I-shaped plate is located above the processing table. The four guide rods slide through the four corners of the I-shaped plate. The first spring is sleeved on the guide rods and installed between the I-shaped plate and the processing table. The mold handle is installed at the center of the top of the I-shaped plate.

[0008] As a further technical solution of this utility model, the stamping mechanism includes a stamping rod, a stamping head, a positioning member, and a second spring. The stamping head is installed at the bottom end of the stamping rod and is located directly above the bearing member. The top end of the stamping rod is connected to the bottom of the I-shaped plate. The positioning member is slidably sleeved with the stamping rod and is connected to the bottom of the I-shaped plate through the second spring.

[0009] As a further technical solution of this utility model, the grinding component includes a polishing wheel and a rotating rod, the rotating rod being coaxially mounted on the bottom of the polishing wheel, and the polishing wheel being located directly below the bearing component.

[0010] As a further technical solution of this utility model, the driving component includes a strip-shaped shell, sprockets, chains, pins, and a motor. The processing table has symmetrical through slots on both sides. The end of the strip-shaped shell passes through the through slot. The motor is installed on the top of the strip-shaped shell near one end, and the output shaft of the motor extends into the inner cavity of the strip-shaped shell. The pin is coaxially connected to the rotating rod and is rotatably installed inside the strip-shaped shell. Multiple sprockets are respectively sleeved with the pin and the output shaft of the motor, and the multiple sprockets are connected to each other by chains.

[0011] As a further technical solution of this utility model, the positioning component includes a lifting plate and a rotating pressure ring. The lifting plate is slidably sleeved with the stamping rod, the bottom end of the second spring is connected to the top of the lifting plate, and the rotating pressure ring is rotatably sleeved with the lifting plate.

[0012] As a further technical solution of this utility model, cylinders are symmetrically installed on the outer side walls of both sides of the processing table, and the piston rod of the cylinder is connected to the lower end surface of the strip shell.

[0013] As a further technical solution of this utility model, a pull-out box with a handle is slidably provided on the side wall near the bottom of the processing table.

[0014] As a further technical solution of this utility model, a guide seat is installed on the top of the strip-shaped shell inside the processing table. The guide seat is inclined on both sides along its length direction, and the guide seat is provided with a notch for rotating the rotating rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, by setting up multiple grinding parts that are driven by a driving component and can be raised, lowered and rotated synchronously, it is convenient to drive the grinding parts to rise and rotate immediately after the stamping mechanism completes the punching from the inside to the outside, so as to remove the burrs generated on the outer wall of the shell body due to the punching at the same time. This realizes the integration and automation of the punching and deburring process, greatly shortens the processing flow, and effectively solves the problem of low processing efficiency caused by the need for a separate subsequent deburring process in the prior art.

[0016] 2. In this utility model, by integrating the punching fixture and deburring function into the processing table, the outer burrs generated by punching from the inside out can be processed immediately under the same clamping and positioning. This not only avoids the dilemma of burrs being difficult to clean when they are located inside in the traditional method, but also eliminates the positioning errors and time waste caused by the turnover of workpieces between multiple processes. Thus, while improving efficiency, it ensures the stability and consistency of processing quality. Attached Figure Description

Detailed Implementation

[0019] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0020] like Figures 1-5 As shown, a punching fixture for processing the housing of a solenoid valve includes a hollow processing table 100. Multiple support members 200 extending into the inner cavity are embedded in the top of the processing table 100. A lifting assembly 300 is mounted on the top of the support members 200, and a stamping mechanism 400 is installed on the lifting assembly 300. The stamping mechanism 400 is used to punch the housing body 500 placed inside the support members 200. A liftable drive member 600 is provided inside the processing table 100. A grinding member 700 located directly below the support members 200 is installed on the drive member 600, and the drive member 600 is used to drive the multiple grinding members 700 to rotate synchronously. After the bottom end of the housing body 500 is punched, the drive member 600 drives the grinding members 700 to rise and rotate, thereby removing the burrs generated after punching the bottom end of the housing body 500.

[0021] It should be noted that during use, the outer shell body 500 to be processed is first placed on the carrier 200. The lifting component 300 drives the stamping mechanism 400 to move downward, performing a punching operation from the inside to the outside on the bottom end of the outer shell body 500. After punching is completed, the lifting component 300 moves up to a set height, and then controls the drive component 600 to rise. The drive component 600 drives multiple grinding components 700 on it to rotate synchronously, so that the rotating grinding components 700 accurately contact and grind the burrs generated on the outside after punching the bottom end of the outer shell body 500, thereby realizing continuous automated operation of punching and deburring.

[0022] like Figures 2-3 As shown, the carrier 200 includes a cylindrical body 201 and an annular opening 202. The cylindrical body 201 has an opening at the top, and the annular opening 202 is located at the center of the bottom end of the cylindrical body 201. The diameter of the annular opening 202 is smaller than the outer diameter of the outer shell body 500.

[0023] It should be noted that in this embodiment, the annular opening 202 allows the stamping head 402 of the stamping mechanism 400 to pass through, and the waste material formed after the outer shell body 500 is punched can fall through the annular opening 202; the inner diameter of the bearing member 200 is equal to the outer diameter of the outer shell body 500, which facilitates the limiting and prevents the outer shell body 500 from shaking during the punching process.

[0024] like Figures 1-2 As shown, the lifting assembly 300 includes an I-shaped plate 301, guide rods 302, a mold handle 303, and a first spring 304. The I-shaped plate 301 is located above the processing table 100. The four guide rods 302 slide through the four corners of the I-shaped plate 301 respectively. The first spring 304 is sleeved on the guide rods 302 and is installed between the I-shaped plate 301 and the processing table 100. The mold handle 303 is installed at the top center of the I-shaped plate 301.

[0025] It should be noted that the die handle 303 facilitates connection with an external stamping machine, thereby realizing the lifting and lowering control of the I-shaped plate 301. The guide rod 302 facilitates the lifting and lowering of the I-shaped plate 301, and the first spring 304 facilitates the buffering and resetting functions.

[0026] like Figure 1 and Figure 3 As shown, the stamping mechanism 400 includes a stamping rod 401, a stamping head 402, a positioning member 403, and a second spring 404. The stamping head 402 is installed at the bottom end of the stamping rod 401 and is located directly above the bearing member 200. The top end of the stamping rod 401 is connected to the bottom of the I-shaped plate 301. The positioning member 403 is slidably sleeved with the stamping rod 401 and is connected to the bottom of the I-shaped plate 301 through the second spring 404.

[0027] It should be noted that when the stamping begins, the I-shaped plate 301 drives the stamping head 402 and the positioning member 403 to descend synchronously via the stamping rod 401. The stamping head 402 can smoothly enter the inner cavity of the outer shell body 500 to be punched, while the positioning member 403 will cover the top of the outer shell body 500. As a result, the positioning member 403 will no longer be able to move downward during the subsequent descent process, thereby causing relative sliding between the stamping rod 401 and the positioning member 403 and compressing the second spring 404. The reaction force of the second spring 404 facilitates the positioning member 403 to press and position the outer shell body 500, while the stamping head 402 can perform the punching operation from the inside to the outside on the bottom of the outer shell body 500.

[0028] like Figure 2 and Figure 4As shown, the polishing component 700 includes a polishing wheel 701 and a rotating rod 702. The rotating rod 702 is coaxially mounted on the bottom of the polishing wheel 701, and the polishing wheel 701 is located directly below the support component 200.

[0029] It should be noted that in this embodiment, the diameter of the polishing wheel 701 is slightly smaller than the diameter of the annular opening 202, but the projection of the polishing wheel 701 can cover the punching head 402. That is to say, after the grinding part 700 rises, the polishing wheel 701 can enter the annular opening 202 and fit against the bottom end of the outer shell body 500. Furthermore, the polishing wheel 701 can cover the hole formed by punching at the bottom end of the outer shell body 500, thereby facilitating the complete removal of burrs generated by punching when the polishing wheel 701 rotates.

[0030] like Figure 1 and Figure 5 As shown, the drive unit 600 includes a strip-shaped shell 601, sprockets 602, chain 603, pin 604, and motor 605. The processing table 100 has symmetrical through slots on both sides. The end of the strip-shaped shell 601 passes through the through slot. The motor 605 is installed on the top of the strip-shaped shell 601 near one end, and the output shaft of the motor 605 extends into the inner cavity of the strip-shaped shell 601. The pin 604 is coaxially connected to the rotating rod 702, and the pin 604 is rotatably installed inside the strip-shaped shell 601. Multiple sprockets 602 are respectively sleeved with the pin 604 and the output shaft of the motor 605, and the multiple sprockets 602 are connected to each other by the chain 603.

[0031] It should be noted that when the motor 605 is working, it drives multiple pins 604 to rotate synchronously through the sprocket 602 and chain 603, thereby causing the rotating rod 702 to drive the polishing wheel 701 to rotate, thus achieving burr removal.

[0032] like Figures 2-3 As shown, the positioning component 403 includes a lifting plate 4031 and a rotating pressure ring 4032. The lifting plate 4031 is slidably sleeved with the stamping rod 401. The bottom end of the second spring 404 is connected to the top of the lifting plate 4031. The rotating pressure ring 4032 is rotatably sleeved with the lifting plate 4031.

[0033] It should be noted that in this embodiment, the rotating pressure ring 4032 is used to press the top edge of the outer shell body 500, and its bottom is provided with an anti-slip pad to increase friction. The rotating pressure ring 4032 and the lifting plate 4031 are rotatably connected by a bearing. Since the bottom of the outer shell body 500 will vibrate when it is polished, the outer shell body 500 will inevitably rotate slightly axially, which facilitates the rotation of the rotating pressure ring 4032 relative to the lifting plate 4031, making the second spring 404 less prone to twisting.

[0034] like Figure 1 and Figure 4As shown, cylinders 101 are symmetrically installed on the outer side walls of both sides of the processing table 100, and the piston rod of the cylinder 101 is connected to the lower end surface of the strip shell 601.

[0035] It should be noted that the cylinder 101 is used to conveniently control the lifting and lowering of the strip shell 601.

[0036] like Figures 1-2 As shown, a pull-out box 102 with a handle is slidably disposed on the side wall near the bottom of the processing table 100.

[0037] It should be noted that the pull-out box 102 facilitates the automatic collection of waste generated during the stamping and deburring processes.

[0038] like Figure 2 and Figure 4 As shown, a guide seat 800 is installed on the top of the strip shell 601 located in the processing table 100. The guide seat 800 is inclined on both sides along its length direction, and the guide seat 800 is provided with a notch for rotating rod 702 to rotate.

[0039] It should be noted that in this embodiment, if the waste generated from punching falls directly onto the polishing wheel 701, the centrifugal force generated during the deburring process will automatically throw the waste off because the polishing wheel 701 is started to rotate first during the deburring process. The small waste generated during the deburring process will inevitably fall onto the top of the strip shell 601. The inclined guide seats 800 on both sides can conveniently guide the material, making it difficult for the waste to accumulate on the top of the strip shell 601.

[0040] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
