Description

Technical Field

[0001] This utility model relates to the field of punch press equipment technology, and in particular to an oil recovery structure applied to the punch press slide mechanism. Background Technology

[0002] In the operation of a traditional punch press slide mechanism, oil lubrication is crucial for ensuring the normal operation of moving parts, reducing friction and wear, and extending component lifespan. However, in traditional structures, a sealing ring is typically installed between the moving shaft and the center sleeve to prevent oil leakage at the slide mechanism location. But in actual use, due to the high-speed movement of the moving parts and the complex working environment, oil easily leaks from the sealing ring, contaminating the surface of mechanical parts, affecting the normal operation and maintenance of the equipment, and also wasting oil and increasing operating costs. Therefore, it is necessary to improve the existing structure. Summary of the Invention

[0003] The technical problem solved by this utility model is to address the deficiencies in the prior art by providing an oil recovery structure for a punch press slide mechanism, thereby solving the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: an oil recovery structure applied to a punch press slide mechanism, comprising: a machine tool, the machine tool being used to install and support mechanical components; the machine tool having one or more mounting holes; a flywheel crankshaft mechanism, the flywheel crankshaft mechanism being disposed on the upper part of the machine tool and used to output power; a motion component, the motion component being disposed within the mounting holes and connected to the flywheel crankshaft mechanism; the motion component comprising a central sleeve embedded in the mounting holes, a copper sleeve embedded in the central sleeve, and a moving part embedded in the copper sleeve. The device includes a moving shaft and an oil seal cap fitted onto the central sleeve; the inner wall of the copper sleeve has grooves for supplying oil, and a first sealing ring is fitted onto the lower edge of the copper sleeve, the first sealing ring fitting against the inner wall of the central sleeve and the outer wall of the moving shaft; the oil seal cap locks the first sealing ring onto the copper sleeve; wherein, a second sealing ring is provided at the lower end of the oil seal sleeve and the moving shaft, there is a gap between the oil seal sleeve and the moving shaft, and the oil seal sleeve has one or more first oil outlets, the first oil outlets being connected to an oil tank via pipes; and a slider connected to the lower end of the moving shaft.

[0005] Furthermore, the machine tool is provided with two mounting holes, which are spaced apart, and the motion components are respectively mounted in the mounting holes.

[0006] Furthermore, the motion shaft includes an adjusting steel pipe, an adjusting screw disposed inside the adjusting steel pipe, and an adjusting pad disposed at the lower end of the adjusting screw; the upper part of the adjusting steel pipe is threadedly connected to the upper part of the adjusting screw, and the adjusting pad is connected to the adjusting steel pipe and the slider by bolts.

[0007] Furthermore, the adjusting pad has an upwardly protruding rim on its circumferential edge, and the adjusting pad has one or more second oil outlets, which are connected to the oil tank via pipes.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows: Double oil seal structure: A first sealing ring is set on the lower edge of the copper sleeve, and it fits against the inner wall of the central sleeve and the outer wall of the moving shaft. At the same time, the first sealing ring is locked on the copper sleeve by the oil seal cover, which enhances the sealing effect. In addition, a second sealing ring is set on the oil seal sleeve and the lower end of the moving shaft, which further doubles the sealing performance, effectively prevents oil leakage, keeps the mechanical parts clean, and is conducive to the normal operation and maintenance of the equipment.

[0009] Oil recovery and reuse: The oil seal sleeve has one or more first oil outlets connected to the oil tank via pipes. When oil leaks to the second sealing ring, the oil is discharged from the first oil outlet of the sealing sleeve and recovered to the oil tank via pipes. The adjusting shim plate also has one or more second oil outlets, similarly connected to the oil tank via pipes. When the second sealing ring leaks, the leaking oil flows to the adjusting shim plate, is discharged through the second oil outlet on the adjusting shim plate, and is recovered to the oil tank via pipes. This design ensures that even if a small amount of oil leaks, it can be promptly returned to the oil tank through the outlets, achieving oil recovery and reuse, reducing oil waste, and lowering operating costs.

[0022] In view of the technical problems described in the background art, such as Figure 1-9As shown, an oil recovery structure for a punch press slide 13 mechanism is provided, comprising: a machine tool 1 for mounting and supporting mechanical components; the machine tool 1 having one or more mounting holes 2; a flywheel crankshaft mechanism 3 disposed on the upper part of the machine tool 1 for outputting power; and a motion assembly 4 disposed within the mounting holes 2 and connected to the flywheel crankshaft mechanism 3; the motion assembly 4 including a central sleeve 5 embedded in the mounting holes 2, a copper sleeve 6 embedded in the central sleeve 5, a motion shaft 7 embedded in the copper sleeve 6, and a sleeve on the central sleeve 5. The oil seal cap 8 is provided on the upper part of the copper sleeve 6; the inner wall of the copper sleeve 6 is provided with a groove 9 for supplying oil; the lower edge of the copper sleeve 6 is fitted with a first sealing ring 10, which fits against the inner wall of the central sleeve 5 and the outer wall of the motion shaft 7; the oil seal cap 8 locks the first sealing ring 10 on the copper sleeve 6; wherein, the lower end of the oil seal sleeve and the motion shaft 7 is provided with a second sealing ring 11, there is a gap between the oil seal sleeve and the motion shaft 7, and the oil seal sleeve is provided with one or more first oil outlets 12, which are connected to the oil tank through pipes; slider 13 is connected to the lower end of the motion shaft 7.

[0023] This utility model provides an oil recovery structure for a punch press slide block 13 mechanism, which mainly consists of a machine tool 1, a flywheel crankshaft mechanism 3, a motion component 4 and a slide block 13.

[0024] In the above technical solution, the machine tool 1 serves as a basic component for installing and supporting other mechanical components, and has one or more mounting holes 2. The structure of the mounting holes 2 is designed to be adapted to the motion component 4.

[0025] The flywheel crankshaft mechanism 3 is mounted on the upper part of the machine tool 1 and is the power output source for the entire punch press slide 13 mechanism. Through the rotation of the flywheel and the transmission of the crank, power is transmitted to the motion component 4, driving the slide 13 to reciprocate up and down, thereby realizing the punching function of the punch press. This is existing technology and not an improvement of this technical solution, so it will not be described in detail here.

[0026] The motion assembly 4 is installed in the mounting hole 2 and connected to the flywheel crankshaft mechanism 3, while the slider 13 is connected to the lower end of the motion shaft 7. The structure of the motion assembly 4 includes a central sleeve 5, a copper sleeve 6, a motion shaft 7, and an oil seal cover 8. The central sleeve 5 is a hollow structure, embedded in the mounting hole 2 of the machine tool 1, and fixed to the mounting hole 2 by bolts. It serves as the basic support structure of the motion assembly 4, providing installation positions and guidance for other components. The copper sleeve 6 is embedded in the central sleeve 5, and its inner wall has grooves 9 for supplying oil. These grooves 9 can store and transport oil, ensuring that the motion shaft 7 is adequately lubricated during movement, reducing friction and wear. The motion shaft 7, embedded in the copper sleeve 6, is the direct driving component for the movement of the slider 13. The motion shaft 7 is connected to the slider 13, and under the drive of the flywheel crankshaft mechanism 3, the motion shaft 7 drives the slider 13 to move. The oil seal cover 8 is fitted on the central sleeve 5, and its function is to lock the first sealing ring 10 onto the copper sleeve 6. The locking of the oil seal cover 8 enhances the sealing effect of the first sealing ring 10, preventing oil leakage from the gap between the copper sleeve 6, the central sleeve 5, and the moving shaft 7. The first sealing ring 10 is fitted onto the lower edge of the copper sleeve 6, fitting snugly against the inner wall of the central sleeve 5 and the outer wall of the moving shaft 7. The first sealing ring 10 provides a preliminary seal, preventing oil leakage from the edge of the copper sleeve 6. A second sealing ring 11 is provided at the lower end of the oil seal sleeve and the moving shaft 7, with a gap between them. The oil seal sleeve has one or more first oil outlets 12, which are connected to the oil tank via pipes. When oil leaks to the position of the second sealing ring 11, the oil will be discharged from the first oil outlet 12 of the oil seal sleeve and returned to the oil tank via pipes.

[0027] The slider 13 is connected to the lower end of the motion shaft 7. Driven by the flywheel crank mechanism and the motion component 4, it moves up and down reciprocatingly to realize the stamping process of the workpiece.

[0028] In the above technical solution, a first sealing ring 10 is provided on the lower edge of the copper sleeve 6, and it fits against the inner wall of the central sleeve 5 and the outer wall of the motion shaft 7. At the same time, the first sealing ring 10 is locked on the copper sleeve 6 by the oil seal cover 8, which enhances the sealing effect. In addition, a second sealing ring 11 is provided at the lower end of the oil seal sleeve and the motion shaft 7, which further doubles the sealing performance, effectively prevents oil leakage, keeps the mechanical parts clean, and is conducive to the normal operation and maintenance of the equipment.

[0029] Meanwhile, the oil seal sleeve has one or more first oil outlets 12, which are connected to the oil tank via pipes. When oil leaks to the position of the second sealing ring 11, the oil is discharged from the first oil outlet 12 of the sealing sleeve and recycled back to the oil tank through pipes. This design ensures that even if a small amount of oil leaks, it can be promptly returned to the oil tank through the outlet, achieving oil recycling, reducing oil waste, and lowering operating costs. like Figure 2As shown, the machine tool 1 is provided with two mounting holes 2, which are spaced apart, and the motion component 4 is provided in each mounting hole 2.

[0030] Preferably, this spacing helps to rationally distribute the moving components 4, ensuring the stability and balance of the overall structure. Each mounting hole 2 is provided with a moving component 4 to provide support and guidance for the movement of the slider 13.

[0031] refer to Figure 5 and 7 As shown, the motion shaft 7 includes an adjusting steel pipe 14, an adjusting screw 15 disposed inside the adjusting steel pipe 14, and an adjusting pad 16 disposed at the lower end of the adjusting screw 15; the upper part of the adjusting steel pipe 14 is threadedly connected to the upper part of the adjusting screw 15, and the adjusting pad 16 is connected to the adjusting steel pipe 14 and the slider 13 by bolts.

[0032] The motion shaft 7 includes an adjusting steel pipe 14, an adjusting screw 15, and an adjusting shim 16. The upper part of the adjusting steel pipe 14 is connected to the upper part of the adjusting screw 15 by a thread. This connection method facilitates the adjustment of the length of the motion shaft 7 to meet different working requirements. The adjusting shim 16 is connected to the adjusting steel pipe 14 and the slider 13 by bolts, ensuring the stability and reliability of the connection.

[0033] like Figure 9 As shown, the circumferential edge of the adjusting pad 16 is provided with an upwardly protruding rim 17, and the adjusting pad 16 is provided with one or more second oil outlets 18, which are connected to the oil tank through pipes.

[0034] If the second sealing ring 11 leaks, the leaked oil will flow to the adjusting shim 16. The surrounding edge 17 of the adjusting shim 16 can prevent oil from overflowing. The adjusting shim 16 has one or more second oil outlets 18, and the second oil outlets 18 are connected to the oil tank through pipes. The oil is discharged through the second oil outlets 18 on the adjusting shim 16 and recycled back to the oil tank through pipes, realizing the secondary recycling of the oil.

[0035] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
