Description

Technical Field

[0001] This utility model relates to the field of filter production and processing technology, and in particular to a special machine for riveting filter screens in a filter. Background Technology

[0002] An oil strainer, typically referring to a machine oil filter, is installed before the oil pump inlet. Its main function is to prevent larger mechanical impurities from entering the oil pump, ensuring the cleanliness and lubrication of the engine oil. Furthermore, the oil strainer helps reduce friction between moving parts in the engine, minimizing wear and tear, thereby extending the engine's lifespan.

[0003] The existing filter screens of the filter collectors are assembled using a process of first pressing and riveting the screen and then welding it. This process easily leads to welding slag that is difficult to clean, causing quality problems. Therefore, it is necessary to remove the welding slag before pressing and riveting the filter screen. Since many filter collectors use this type of screen, a special machine needs to be manufactured to achieve this for versatility and mass production.

[0004] Based on this, a special machine for riveting filter screens of a filter collector was developed to overcome the above-mentioned technical problems. Utility Model Content

[0023] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0024] Example

[0025] like Figure 1 As shown, the filter screen pressing and riveting machine of this embodiment includes a platform 1, a split lower mold 2, an upper mold 3, a machine frame 4, a loading device 5, and a lateral propulsion device 6. The split lower mold 2 includes a fixed lower mold 21 and a movable lower mold 22 that are horizontally spaced apart. The fixed lower mold 21 is fixed to the upper end of the platform 1. The lateral propulsion device 6 is mounted on the platform 1 and connected to the movable lower mold 22, used to drive the movable lower mold 22 to move horizontally closer to or away from the fixed lower mold 21. The upper ends of mold 21 and movable lower mold 22 are respectively provided with an extension (a in the figure) on the side close to each other. The area for clamping workpiece 10 is defined between the two extensions and the upper part. The special machine frame 4 is mounted on the upper end of the platform 1 and is located outside the split lower mold 2. The loading device 5 is mounted on the upper end of the special machine frame 4. The upper mold 3 is located above the fixed lower mold 21 and movable lower mold 22 and is connected to the loading device 5. The loading device 5 is used to drive the upper mold 3 to move up and down.

[0026] In this embodiment, the filter screen riveting machine pre-loads the workpiece 10 with an oil separator (workpiece 10 includes an upper cover and a pipe bend welded to the middle of the lower end of the cover, with the oil separator inside the cover). During processing, the horizontal propulsion device 6 drives the split lower mold 2 to open, that is, drives the movable lower mold 22 to move away from the fixed lower mold 21 a certain distance. Then, the workpiece 10 is loaded. Specifically, the bend is inserted between and below the extension of the fixed lower mold 21 and the movable lower mold 22, and the cover is placed on the upper end of the extension. Subsequently, the movable lower mold 22 is moved closer to the fixed lower mold 21 by the lateral propulsion device 6 until the workpiece 10 is stably clamped and placed. In this state, the upper mold 3 is located above the gap between the fixed lower mold 21 and the movable lower mold 22. The loading device 5 applies downward loading to the upper mold 3, causing the upper mold 3 to press and rivet the oil distribution screen in the cover to the cover. Afterward, the loading device 5 drives the upper mold to move upward back to its original position, and the lateral propulsion device 6 drives the movable lower mold 22 away from the fixed lower mold 21. The riveted workpiece 10 can then be removed. The overall structural design is simple and reasonable, and can adapt to the production process and workpieces of filter collectors that require welding before riveting the filter screen. It can solve the technical problems of achieving universality and mass production of various filter collectors with welded bent pipes and riveted filter screens.

[0027] In a preferred embodiment, the upper ends of the extensions of the fixed lower mold 21 and the movable lower mold 22 are respectively provided with limiting blocks 7 for restricting both sides of the workpiece 10.

[0028] In the above embodiment, after the fixed lower mold 21 and the movable lower mold 22 separate and the workpiece 10 is inserted, the fixed lower mold 21 and the movable lower mold 22 move closer to each other until the limiting blocks 7 on their upper parts respectively abut against the two sides of the cover of the workpiece 10, thereby stably clamping the workpiece 10. Next, the loading device 5 can drive the upper mold 3 to move for riveting operation. The design of the limiting block 7 can ensure that the cover of the workpiece 10 is well clamped, ensuring that the cover will not shift during the subsequent riveting process and guaranteeing the accuracy of riveting the workpiece 10.

[0029] In this embodiment, the aforementioned limiting block 7 is a long, straight sheet metal part with an L-shaped cross-section, and they are parallel to each other.

[0030] In this embodiment, the special-purpose machine frame 4 is a gate-shaped frame. It is erected above the split lower mold 2, and part of the lateral propulsion device 6 passes through one side of the special-purpose machine frame 4 and is connected to the movable lower mold 22.

[0031] In this embodiment, the loading device 5 is a hydraulic cylinder, which is connected to the hydraulic station 8 via a hydraulic cylinder pipeline. The hydraulic station 8 provides hydraulic pressure for the operation of the loading device 5.

[0032] In this embodiment, the lateral propulsion device 6 is a hydraulic cylinder, which is connected to the hydraulic station 8 via a hydraulic cylinder pipeline. The hydraulic station 8 provides hydraulic pressure to the loading device 5, and the design of the hydraulic cylinder makes the lateral propulsion relatively smooth.

[0033] In this embodiment, as Figure 2 As shown, it also includes an electrical control cabinet 9, which is connected to the electrical units within the hydraulic station 8. The electrical units include a hydraulic pump, solenoid valves, etc., and the hydraulic supply from the hydraulic station 8 to the hydraulic cylinders can be controlled via the electrical control cabinet 9.

[0034] In this embodiment, the electrical control cabinet 9 is mounted at the lower end of the platform 1. The overall structural layout is more compact.

[0035] In a preferred embodiment, the platform 1 is provided with a slide rail, the lower end of the movable lower mold 22 is mounted on the slide rail, and can move along the slide rail to approach or move away from the fixed lower mold 21.

[0036] In the above implementation scheme, the design of the slide rail ensures the accuracy and direction of the movement of the movable lower mold 22.

[0037] In this embodiment, an elastic support seat is provided below the fixed lower mold 21 and the movable lower mold 22 for abutting against the lower end of the workpiece 10. The design of this elastic support seat facilitates demolding of the workpiece 10 after riveting. Specifically, after riveting is completed, the elastic support seat uses elastic force to push the workpiece 10 upward to demold. Before riveting, the elastic support seat is compressed and stores energy because the workpiece 10 is stably clamped.
