Description

Technical Field

[0001] This utility model belongs to the field of filter housing production technology, specifically relating to a filter housing processing punching device. Background Technology

[0002] As a key component in a vehicle engine system, the filter's housing is typically made of metal and requires drilling before assembly to facilitate airflow connection or structural positioning. Current filter housing punching processes mostly employ manual loading and point-to-point punching. While this method accomplishes basic machining tasks, it still suffers from the following problems:

[0003] First, traditional punching devices are mostly static worktables, requiring operators to manually load and unload materials during processing, which is inefficient and can easily cause operator fatigue in repetitive operations, affecting processing stability and safety.

[0004] Secondly, existing punching equipment is not good at handling the discharge of residual material after punching. The punched waste material is easy to accumulate inside the mold or table. If it is not cleaned in time, it will cause the mold groove to be blocked, affecting the accurate placement of subsequent workpieces, or even causing damage to the mold.

[0005] Furthermore, if the excess material during the punching process cannot be effectively removed, it may interfere with the positioning and processing of the next workpiece. In severe cases, it may lead to processing errors or equipment jamming, reducing the continuous operation capability of the entire machine.

[0006] In addition, traditional devices cannot achieve continuous rotation and positioning of the workpiece during the punching process. They often require multiple manual angle adjustments to complete multi-face punching, which is cumbersome and has errors in angle control, affecting the consistency of the punching position of the shell. Utility Model Content

[0007] To address the problems existing in the prior art, the purpose of this utility model is to provide a filter housing processing punching device that can automatically complete multi-sided punching, has front-side loading and rear-side automatic unloading functions, and has the ability to guide residual material after punching. This improves processing efficiency and automation level, and solves the problems of low punching efficiency, residual material accumulation, and inaccurate processing position in the prior art.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a filter housing processing punching device, comprising a punching worktable, a support frame installed on the top of the punching worktable, a rotating cylinder rotatably installed inside the support frame, the rotating cylinder having a regular hexagonal cross-section and being hollow inside, and multiple mold grooves opened on each side of the rotating cylinder;

[0009] The top of the support frame is uniformly equipped with main cylinders, and the output end of the main cylinder is equipped with a stamping die head, which corresponds to the mold groove.

[0010] The support frame has symmetrical mounting plates on one side, and a scrap material guide plate is rotatably installed between the two mounting plates. The scrap material guide plate passes through the rotating cylinder and is in an inclined state. The scrap material guide plate is used to discharge the scrap material under stamping.

[0011] Furthermore, an inclined plate is provided on the lower inner side of the support frame, the inclined plate is located below the rotating cylinder, and the inclined plate has a structure that is higher in the front and lower in the back.

[0012] Furthermore, both ends of the rotating cylinder are provided with extension cylinders, which penetrate the side surface of the support frame. An external toothed ring is installed on the surface of one of the extension cylinders, and the external toothed ring is placed on the outside of the support frame.

[0013] Furthermore, a drive gear is installed on one side of the support frame, and the drive gear meshes with the external gear ring.

[0014] Furthermore, one of the extension tubes has wavy protrusions evenly arranged on the surface of one end away from the mounting plate with its rotation axis as the center, and a protruding plate is arranged on the lower side of one side of the support frame, the protruding plate being placed below the wavy protrusions.

[0015] Furthermore, a sliding rod is vertically slidably mounted on the surface of the convex plate. The sliding rod has a square cross-section and a mounting head is provided at the top of the sliding rod. The mounting head is located on the outer side of one end of the excess material guide plate.

[0016] Furthermore, two fixing bolts are provided on one side of the mounting head, the end of the residual material guide plate is placed between the two fixing bolts, and an extrusion roller is rotatably mounted on one side of the mounting head surface. The rotation axis of the extrusion roller is horizontally set, and the extrusion roller is placed below the extension cylinder and in contact with the surface of the corrugated protrusion.

[0017] Furthermore, a spring is fitted onto the surface of the slide rod, the spring being positioned between the convex plate and the mounting head, and the spring exerting an upward thrust on the mounting head.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention utilizes a rotating drum with a hexagonal cross-section and mold grooves on each side to enable continuous arrangement and punching of end caps for multi-faceted filter housings. The drum rotates in stages via a drive gear and an external gear ring, completing one face displacement with each 60-degree rotation. Multiple facets can be punched continuously with a single loading operation, avoiding the need for repeated manual angle adjustments in existing technologies and significantly improving punching efficiency and positioning accuracy.

[0020] By positioning the main cylinder and the stamping die above the rotating drum, and ensuring that the stamping die aligns with the die groove, the main cylinder can drive the stamping die to press down and complete the punching operation after the rotating drum has rotated to the correct position. This ensures that the stamping action is vertical and stable. The precise fit between the stamping die and the die groove improves the punching accuracy, reduces workpiece displacement and deviation, and solves the problem of punching misalignment caused by inaccurate positioning in existing stamping structures.

[0021] By opening through holes at the bottom of the mold groove and setting inclined plates and finished product guide structures, a streamlined processing method of front-side loading and rear-side automatic unloading is realized. The stamped filter housing is guided by the inclined plates and slides smoothly into the finished product box. The whole process does not require manual intervention, has a high degree of automation, avoids delays in cycle time or accidental injury caused by manual part handling, and solves the problems of low unloading efficiency and poor safety in the existing technology.

[0022] By setting a residual material guide plate that runs through the inside of the rotating drum, the punched residual material is directly guided onto the guide plate through the through hole at the bottom of the die groove. The residual material is then discharged to the outside of the device through the inclined structure of the residual material guide plate, realizing automatic collection and processing of residual material. This avoids the accumulation of residual material in the die groove or rotating drum, thereby effectively preventing die groove blockage and improving the continuity of subsequent punching operations.

[0023] By setting corrugated protrusions on the surface of the rotating drum extension cylinder and setting extrusion rollers, slide bars, installation heads and other vibration mechanisms in contact with them, when the rotating drum rotates, the end of the residual material guide plate will generate periodic vibration under the action of the corrugated protrusions. This effectively avoids the accumulation or jamming of stamping residual material on the guide plate, improves the residual material discharge efficiency, and solves the problems of residual material blockage and poor sliding in the existing technology.

[0024] By setting a spring on the slide bar, a continuous upward thrust is provided to the mounting head, ensuring that the extrusion roller always remains in contact with the wave protrusion. This ensures that the mounting head can slide stably up and down during the rotation of the drum and drive the residual material guide plate to vibrate, effectively improving the stability and reliability of residual material conveying and avoiding vibration interruption caused by roller detachment or movement failure.

[0034] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0035] refer to Figures 1-6 As shown, a filter housing punching device includes a punching worktable 1, with a support frame 12 mounted on the top of the punching worktable 1; a rotating cylinder 4 is rotatably mounted inside the support frame 12 via a bearing assembly; the rotating cylinder 4 has a regular hexagonal cross-section and is hollow inside to accommodate punched-out residual material; each side of the rotating cylinder 4 has multiple mold grooves 41 for accommodating the filter housing end caps to be processed, and the bottom of the mold grooves 41 has through holes for residual material to fall; the rotating cylinder 4 is made of a hollow metal tube, with extension cylinders 42 connected to both ends to enhance axial stability and form a continuous rotation path in the structure.

[0036] The main cylinders 2 are evenly installed on the top of the support frame 12. The main cylinders 2 are connected to the air pump through the air source interface to provide stable stamping power. The output end of the main cylinder 2 is equipped with a stamping die 3. The stamping die 3 is vertically aligned with the die groove 41 and can slide smoothly along the guide rod to complete the stamping action. The stamping die 3 is made of high-strength alloy material and has good wear resistance and impact strength. The main cylinder 2 is controlled by the PLC system to control its stamping rhythm and achieve precise punching of the end cover of the housing.

[0037] The support frame 12 has symmetrical mounting plates 121 on one side, and the two mounting plates 121 are rotatably mounted with a residual material guide plate 5 through the pin shaft. The residual material guide plate 5 passes through the lower structural area of ​​the rotating drum 4 and is arranged in an inclined state in the through hole opened in the support frame 12. The lower end of the residual material guide plate 5 extends to the outside of the device and is connected to the receiving box to discharge and collect the metal residual material under stamping. The surface of the residual material guide plate 5 is smooth and has multiple material discharge grooves to reduce the accumulation of residual material and improve the sliding efficiency.

[0038] refer to Figure 1 As shown, an inclined plate 11 is provided on the lower inner side of the support frame 12. The inclined plate 11 is an integral sheet metal structure and is located directly below the rotating drum 4. The inclined plate 11 has a structure that is higher in the front and lower in the back. The surface is coated with an anti-wear layer to receive the shell end cap that falls after processing and guide it to the finished product collection box. The inclination angle of the inclined plate 11 has been optimized to ensure that the shell slides down smoothly without secondary collision.

[0039] refer to Figure 1 and Figure 5 As shown, both ends of the rotating cylinder 4 are provided with extension cylinders 42, which are integrally formed with the rotating cylinder 4 to enhance the structural rigidity of the rotating cylinder 4; the extension cylinder 42 passes through the side surface of the support frame 12 and is supported by bearings to ensure smooth rotation; an external toothed ring 43 is installed on the outer surface of one of the extension cylinders 42. The external toothed ring 43 is formed by machining hard steel, and its external teeth mesh with the drive gear 8 for stable transmission.

[0040] refer to Figure 1 As shown, a drive gear 8 is installed on one side of the support frame 12. The drive gear 8 is connected to the drive shaft by a motor and rotates. The drive gear 8 meshes with the external gear ring 43. When the drive gear 8 rotates, it drives the rotating drum 4 to rotate in steps at 60-degree intervals, thereby realizing the sequential punching of multiple workstations. This mechanism makes continuous operation of front loading and rear unloading possible, which significantly improves processing efficiency.

[0041] refer to Figure 4 and Figure 5 As shown, one end surface of the extension cylinder 42 facing away from the mounting plate 121 is uniformly provided with wavy protrusions 44 with its rotation axis as the center; the wavy protrusions 44 are multiple arc-shaped protrusions arranged at equal intervals, which periodically contact the device below when the rotating cylinder 4 rotates; a protruding plate 122 is provided on one side of the support frame 12, which is a vertical mounting component fixed on the support frame 12. The protruding plate 122 is placed below the wavy protrusions 44 and is used to support the slide rod 6 and form part of the guide mechanism.

[0042] refer to Figure 4 and Figure 6As shown, a slide rod 6 is vertically slidably mounted on the surface of the convex plate 122. The slide rod 6 is a steel square rod structure with a square cross section to prevent rotational displacement during sliding. A mounting head 61 is provided on the top of the slide rod 6. The mounting head 61 is connected to the slide rod 6 by threads and can be disassembled for maintenance. The mounting head 61 is placed on the outer side of one end of the excess material guide plate 5 and connected to its structure to realize vibration transmission. The slide rod 6 achieves vertical linear sliding within the convex plate 122 through an internal guide sleeve.

[0043] refer to Figure 4 and Figure 6 As shown, two fixing bolts 62 are provided on the upper side of one side of the mounting head 61. The fixing bolts 62 are installed on the top of the mounting head 61 and clamp the end of the residual material guide plate 5 to form a connection. The end of the residual material guide plate 5 is placed between the two fixing bolts 62, and the end vibrates when the mounting head 61 reciprocates to promote the passage of residual material. A pressing roller 63 is rotatably installed on the lower side of one side of the mounting head 61. The rotation axis of the pressing roller 63 is set horizontally, and its surface is covered with a high wear-resistant rubber layer. It is used to contact and rub against the surface of the corrugated protrusion 44 and generate the vertical reciprocating motion of the mounting head 61. The pressing roller 63 is placed below the extension cylinder 42 and keeps in contact with the surface of the corrugated protrusion 44, so that as the rotating cylinder 4 rotates, the mounting head 61 vibrates up and down with the undulation of the corrugated profile.

[0044] refer to Figure 4 As shown, a spring 7 is fitted on the surface of the slide bar 6. The spring 7 is a helical compression spring, and its two ends are connected to the convex plate 122 and the mounting head 61, respectively. The spring 7 provides a continuous upward thrust to the mounting head 61. This structure ensures that the extrusion roller 63 can always fit against the surface of the wave convex block 44 during the rotation of the drum 4, thereby achieving a stable pressing and releasing rhythm. This drives the residual material guide plate 5 to vibrate periodically, effectively preventing residual material accumulation and mold groove blockage.

[0045] The working principle of this utility model is as follows: the drive gear 8 meshes with the external gear ring 43 to control the rotation of the rotating drum 4. After rotating 60 degrees at a time, it pauses so that one side is horizontally placed at the top. The end cap of the housing to be punched is placed inside the mold groove 41 through the front side. When it rotates to the top, the main cylinder 2 controls the punching die head 3 to move down to punch the end cap of the housing. After a single punching is completed, the rotating drum 4 continues to rotate, and the processed housing rotates downward and falls. The punched excess material will fall into the inside of the rotating drum 4 through the hole in the mold groove 41. This structure can feed material on the front side and automatically unload material on the rear side to improve the punching efficiency.

[0046] The finished shell will fall onto the inclined plate 11 to guide it backward into the finished product collection box. The remaining material falls onto the surface of the remaining material guide plate 5. The remaining material is discharged through the inclined remaining material guide plate 5. The remaining material guide plate 5 can vibrate to clear the remaining material. During the rotation of the drum 4, the presence of the spring 7 gives the mounting head 61 an upward thrust, which in turn keeps the extrusion roller 63 in contact with the surface of the wave protrusion 44. Therefore, when the drum 4 rotates, it can drive the mounting head 61 to slide up and down. The cross section of the slide rod 6 is square to ensure the orientation of the extrusion roller 63 and the fixing bolt 62. When the mounting head 61 moves up and down, it can drive the end of the remaining material guide plate 5 to vibrate through the fixing bolt 62, thereby improving the guiding efficiency of the punched material and preventing blockage.

[0047] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
