Description

Technical Field

[0001] The utility model relates to a thin oil lubrication structure for a slide guide rail of a press machine. Background Art

[0002] A press (including punch presses and hydraulic presses) is a versatile, compact machine. Its versatility and high production efficiency make it suitable for a wide range of applications, including cutting, punching, blanking, bending, riveting, and forming. It applies strong pressure to metal blanks, causing them to plastically deform and fracture, ultimately creating parts.

[0003] The existing thin oil lubrication closed double-point press slide guide lubrication is to install an oil receiving tank below the guide rail, the oil passes through the filter and return oil box on the slider, and then the return oil box is connected to the oil leakage box below it with a pipe to return the oil to the lubrication station. In this structure, the guide rail length is not full stroke. When the slider moves up and down, there will be splashes of lubricating oil at the bottom of the guide rail. At the same time, the installation distance between the return oil box and the leakage oil box is difficult to control and the overall appearance is not beautiful. Utility Model Content

[0004] The purpose of the utility model is to solve the above deficiencies in the prior art and to provide a thin oil lubrication structure for a slide rail of a press.

[0005] A thin oil lubrication structure for the slide guide rail of a press comprises a machine body, a slide, and a guide rail. The guide rail is fixedly mounted on the machine body, the slide slides in sliding engagement with the guide rail, an oil receiving box is provided below the guide rail, the oil receiving box is a lidless structure, an oil baffle is provided between the oil receiving box and the guide rail, the upper end of the oil baffle is fixedly connected to the lower end of the slide, the opening of the oil receiving box faces the oil baffle, a portion of the oil baffle is always located in the oil receiving box, and the oil receiving box is connected to a lubrication station via an oil pipe.

[0006] Preferably, the fuselage is provided with four columns, each column is provided with a guide rail, the slider is a rectangular structure, and its four vertical corners are provided with right-angled notches passing through the upper end face and the lower end face, and the right-angled notches are slidably matched with the surface of the guide rail.

[0007] Preferably, the oil baffle is a bent structure, one end of which is provided with a connecting plate, and the oil baffle is fixedly connected to the lower end surface of the slider by bolts passing through the connecting plate.

[0008] Preferably, a detachable wear-resistant block is provided on the contact surface where the right-angle notch is connected to the guide rail surface.

[0009] Beneficial effects: Compared with the existing technology, the utility model adopts a full-stroke long guide rail with high guiding accuracy and good wear resistance; the structure is simple, convenient and easy to install; an extended full-coverage oil baffle is adopted under the slider guide rail. When the slider moves up and down, the oil baffle is always in the oil return box without being exposed, which can prevent oil leakage and lubricating oil splashing.

[0013] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0014] like Figure 1-2 As shown, the fuselage 1, the slider 2, the guide rail 3, the wear-resistant block 4, the oil baffle 5, and the oil receiving box 6;

[0015] A thin oil lubrication structure for the slide guide of a press includes a body 1, a slide 2, and a guide rail 3. The guide rail 3 is fixedly mounted on the body 1, and the slide 2 and the guide rail 3 are slidably matched. An oil receiving box 6 is provided below the guide rail 3. The oil receiving box 6 is a lidless structure. An oil baffle 5 is provided between the oil receiving box 6 and the guide rail 3. The upper end of the oil baffle 5 is fixedly connected to the lower end of the slide 2. The opening of the oil receiving box 6 faces the oil baffle 5. A part of the oil baffle 5 is always located in the oil receiving box 6. The oil receiving box 6 is connected to the lubrication station through an oil pipe.

[0016] In this embodiment, the fuselage 1 is provided with four columns, each of which is provided with a guide rail 3. The slider 2 is a rectangular structure, and its four vertical corners are provided with right-angled notches that pass through the upper end face and the lower end face. The right-angled notches are in sliding cooperation with the surface of the guide rail 3.

[0017] In this embodiment, the oil baffle plate 5 is a bent structure, one end of which is provided with a connecting plate. The oil baffle plate 5 is fixedly connected to the lower end surface of the slider 2 by bolts passing through the connecting plate.

[0018] In this embodiment, a detachable wear-resistant block 4 is provided on the contact surface between the right-angle notch and the surface of the guide rail 3 .

[0019] Instructions for use: The slider 2 is within the length range of the guide rail 3 at both the highest and lowest points. When the slider 2 moves up and down, the oil baffle 5 also moves up and down. The oil baffle 5 completely covers the side where the copper guide plate is installed. The lubricating oil flows into the oil return box through the oil baffle 5 and finally returns to the lubrication station through the pipe.

[0020] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
