Description

Technical Field

[0001] This utility model relates to the technical field of filter end cap processing equipment, specifically an automatic stamping equipment for filter end caps. Background Technology

[0002] In modern industrial manufacturing, filters (such as oil filters, fuel filters, and air filters) are key components of various power equipment and vehicles. Their end caps, as sealing and support structures, directly affect the filter's sealing performance, strength, and service life.

[0003] Traditional filter end cap production relies primarily on manual labor combined with single-station stamping equipment. This method has several drawbacks: firstly, operational safety needs improvement, as operators frequently come into contact with the high-speed stamping equipment, posing a potential risk of mechanical injury; secondly, production efficiency and cost-effectiveness are limited, as manual operation is inefficient and labor costs are high, impacting both overall production efficiency and cost. Therefore, this invention aims to address these issues by providing an automated filter end cap stamping device that reduces the risks of manual operation, improves production efficiency, and enhances product quality. Utility Model Content

[0004] The purpose of this invention is to provide an automatic stamping device for filter end caps to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic stamping device for filter end caps, comprising a support frame,

[0006] The bottom end of the support frame is fixedly connected to a support leg. Servo motors are fixedly connected to the front and rear of the left side of the support frame, respectively. A ball screw is fixedly connected to the output end of the servo motor. The right end of the ball screw is rotatably connected to the inner right wall of the support frame through a limiting ring.

[0007] Furthermore, a ball nut seat is threadedly connected to the middle of the ball screw, and a support plate is fixedly connected to the top of the ball nut seat.

[0008] Furthermore, a limiting horizontal plate is provided at the bottom end of the support plate, the limiting horizontal plate is horizontally slidably connected to the support plate, and the left and right ends of the limiting horizontal plate are fixedly connected to the inner wall of the support frame.

[0009] Furthermore, a material discharge groove is provided between the limiting horizontal plate and the support plate.

[0010] Furthermore, a pad mold is fixedly connected to the top of the support plate by a rivet screw, and four positioning rods are fixedly connected to the top of the pad mold.

[0011] Furthermore, a bracket is fixedly connected to the top middle of the support frame, and protective plates are fixedly connected to the left, right, and rear middle of the bracket.

[0012] Furthermore, a top plate is fixedly connected to the top of the bracket, and a hydraulic cylinder is fixedly connected to the top of the top plate.

[0013] Furthermore, a cylinder barrel is fixedly connected to the output end of the hydraulic cylinder, and the cylinder barrel penetrates the top plate.

[0014] Furthermore, a piston rod is provided in the middle of the cylinder, and a mounting plate is fixedly connected to the lower end of the piston rod. A pressure mold is fixedly connected to the lower end of the mounting plate by a press-fit screw.

[0015] Furthermore, an observation window is rotatably connected to the front side of the bracket via a hinge, and a handle is fixedly connected to the outside of the observation window.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] By incorporating a servo motor, ball screw, ball nut seat, and limit plate, the equipment utilizes a transmission system consisting of a servo motor, ball screw, and ball nut seat. Combined with the guide constraint of the limit plate on the support plate, this achieves precise workpiece positioning and smooth conveying. Compared to traditional manual or pneumatic conveying, this system avoids errors caused by manual workpiece placement, ensures the precision of the fit between the workpiece and the die and pad, improves the dimensional consistency and forming quality of the stamped parts, and allows for adjustable conveying speed via the servo motor, enhancing production efficiency. Furthermore, by setting up a support plate and mounting plate, both the die and pad are fixed to the support plate and mounting plate using rivet screws. On the plate, mold replacement does not require disassembling complex structures, shortening mold change time and allowing for quick switching between different models of filter end cap molds. This adapts to the needs of multi-variety, small-batch production, reducing mold maintenance costs (no need to replace the entire set if a single mold is damaged), and improving equipment utilization. By setting up protective plates and observation windows, the protective plates, made of cold-rolled steel plates, can effectively prevent scrap from splashing or workpieces from popping out during the stamping process and causing injury to operators. The front observation window is made of tempered glass with a handle design, allowing operators to observe the stamping status in real time (such as whether the workpiece is accurately positioned and whether the die is in place), avoiding blind operation.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution for an automatic filter end cap stamping device: An automatic filter end cap stamping device includes a support frame 1, with support legs fixedly connected to the bottom end of the support frame 1. Servo motors 2 are fixedly connected to the front and rear of the left side of the support frame 1, respectively. By setting up the servo motor 2, ball screw 3, ball nut seat 4, and limiting plate 6, the device uses a transmission system of the servo motor 2, ball screw 3, and ball nut seat 4, combined with the guiding constraint of the limiting plate 6 on the support plate 5, to achieve precise positioning and stable conveying of the workpiece. Compared with traditional manual or cylinder conveying, this system: avoids errors caused by manual workpiece placement, ensures the fitting accuracy of the workpiece with the die 17 and the pad die 8, improves the dimensional consistency and forming quality of the stamped parts, and the conveying speed can be adjusted by the servo motor 2 to improve production efficiency. A ball screw is fixedly connected to the output end of the servo motor 2. The right end of the ball screw 3 is rotatably connected to the inner wall of the right side of the support frame 1 via a limiting ring. The ball screw 3 is threaded with a ball nut seat 4 in the middle. The top of the ball nut seat 4 is fixedly connected to a support plate 5. By setting the support plate 5 and the mounting plate 16, the pad mold 8 and the pressing mold 17 are fixed to the support plate 5 and the mounting plate 16 by pressing screws. The mold replacement does not require disassembling the complex structure, shortens the mold replacement time, and allows for quick switching of different models of filter end cap molds. This adapts to the needs of multi-variety small-batch production, reduces mold maintenance costs (no need to replace the whole set if a single mold is damaged), and improves the utilization rate of the equipment. The bottom end of the support plate 5 is provided with a limiting horizontal plate 6. The limiting horizontal plate 6 and the support plate 5 are horizontally slidably connected. The left and right ends of the limiting horizontal plate 6 are fixedly connected to the inner wall of the support frame 1. The limiting horizontal plate 6 and the support plate 5 are both provided with a material drop groove 7 in the middle.

[0028] The top of the support plate 5 is fixedly connected to the die 8 by rivet screws. Four positioning rods 9 are fixedly connected to the top of the die 8. A bracket 10 is fixedly connected to the top of the middle of the support frame 1. Protective plates 11 are fixedly connected to the left, right, rear, and middle of the bracket 10. By setting up the protective plates 11 and observation windows 18, the protective plates 11, made of cold-rolled steel, form a semi-enclosed or fully enclosed protective cover structure with the sides of the bracket 10, the bottom of the top plate 12, and the corresponding edges of the worktable 1. This effectively prevents scrap from splashing or workpieces from ejecting during the stamping process and causing injury to the operator. The front observation window 18 is made of tempered glass and has a handle, allowing the operator to observe the stamping status in real time (e.g., whether the workpiece is positive or negative). To ensure accurate positioning and proper placement of the mold 17, and to avoid blind operation, the protective plate 11 and the observation window 18 can be combined to form an openable sealed structure, ensuring operational safety and preventing waste from spilling out. The top plate 12 is fixedly connected to the top of the bracket 10, and the top of the top plate 12 is fixedly connected to the top of the hydraulic cylinder 13. The output end of the hydraulic cylinder 13 is fixedly connected to the cylinder barrel 14, which penetrates the top plate 12. A piston rod 15 is set in the middle of the cylinder barrel 14, and the lower end of the piston rod 15 is fixedly connected to the mounting plate 16. The lower end of the mounting plate 16 is fixedly connected to the mold 17 by a rivet screw. The front side of the bracket 10 is rotatably connected to the observation window 18 by a hinge, and a handle is fixedly connected to the outside of the observation window 18.

[0029] The servo motor 2 is electrically connected to an external power supply and a central control console 24. The central control console 24 contains a microprocessor and control program, which can precisely control the start, stop, speed and rotation angle of the servo motor 2 according to the set workpiece size, stamping parameters, etc., to achieve precise positioning and smooth conveying of the workpiece. Combined with the feedback of the position sensor, the central control console 24 can realize closed-loop control of the workpiece conveying process. The hydraulic cylinder 13 is connected to the hydraulic pump station set above the top plate 12 of the support 10 through hydraulic pipeline. The hydraulic pump station includes components such as a hydraulic pump, oil tank and directional control valve. The hydraulic pump station is electrically controlled by the central control console 24 and can precisely control the extension, speed and thrust of the hydraulic cylinder 13. A pressure sensor is set below the die 17 or at the end of the piston rod of the hydraulic cylinder 13 to provide real-time feedback of the stamping pressure to the central control console 24, realizing closed-loop control of the stamping process and ensuring the dimensional consistency and forming quality of the stamped parts.

[0030] In use, the filter end cap to be stamped is placed on the die 8. The positioning rod 9 fixes the workpiece position to prevent displacement during stamping. The servo motor 2 starts, driving the ball screw 3 to rotate clockwise, which moves the ball nut seat 4 to the right. This pushes the support plate 5 to slide horizontally along the limiting plate 6, conveying the workpiece to the underside of the stamping station bracket 10. The hydraulic cylinder 13 starts, pushing the mounting plate 16 and the die 17 downward through the piston rod 15. The die and the die work together to stamp the workpiece, performing processes such as stretching and bending. After stamping, the hydraulic cylinder 13 drives the piston rod 15 to rise, and the die 17 returns to its initial position. Then, the servo motor 2 reverses, driving the ball screw 3 to rotate counterclockwise. The ball nut seat 4 moves the support plate 5 to the left, returning to the loading station. At this point, the stamped finished product can be removed from the die 8. The above steps are repeated to achieve continuous automatic stamping.
