Description

Technical Field

[0001] This utility model relates to the field of lubrication of bending cores, and in particular to a lubrication device for bending cores. Background Technology

[0002] The bending core, as a mold component, fills the cavity of the profile. During the bending process, it moves synchronously with the profile through hydraulic or mechanical force, evenly distributing stress and preventing wrinkling of the inner wall or cross-sectional distortion. This is achieved through the fully hydraulic control system of the bending machine, enabling synchronous stretching and bending. It maintains the integrity of the material surface (such as sprayed or electroplated layers), eliminates internal residual stress, and improves dimensional stability. However, when bending aluminum profiles, the bending core lacks a lubrication system, frequently causing it to jam, resulting in the scrapping of the aluminum profile and high repair costs. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a lubrication device for bending cores, which can solve the following technical problems: bending aluminum profiles, bending cores without lubrication devices, bending cores often jamming, resulting in scrapped aluminum profiles, and high cost of core repair.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a lubrication device for a bending core, including an oil tank. The bottom edge of the oil tank is provided with an inclined surface, and a telescopic oil outlet pipe is inserted through the inclined surface. When not lubricating, the telescopic oil outlet pipe can be retracted. A three-connector pipe is inserted through the top surface of the oil tank. The three-connector pipe has a T-shaped structure. Two joints of the three-connector pipe are on the outside of the oil tank. Duckbill valves are provided on the two joints located in the vertical position. The two duckbill valves are arranged in the same direction. The joint in the horizontal position is connected to an air cylinder. Air can be injected into the interior of the oil tank through the air cylinder, thereby guiding the lubricating oil inside from the telescopic oil outlet pipe to the bending core.

[0005] As a preferred embodiment of this utility model, the top surface of the oil tank is provided with a support base, and the top surface of the support base is symmetrically provided with buckles.

[0006] As a preferred embodiment of this utility model, the front side of the oil tank is provided with a groove, and a glass window is embedded inside.

[0007] As a preferred embodiment of this utility model, the top surface of the oil tank is provided with an oil filling port, and an oil filling cap is provided on the oil filling port.

[0008] As a preferred technical solution of this utility model, two mounting holes are symmetrically opened on the side of the inclined surface, and a sealing rubber is provided inside the mounting hole, and the telescopic oil outlet pipe passes through the inside of the sealing rubber.

[0009] As a preferred technical solution of this utility model, L-shaped locking blocks are provided on both sides of the inclined surface. The L-shaped locking blocks are fixed on the outside of the mounting hole. Two limiting plates are fixed on the outside of the telescopic oil outlet pipe. The two limiting plates are respectively inside and outside the oil tank. A through groove is opened on the outside of each limiting plate.

[0010] Compared with the prior art, the beneficial effects that this utility model can achieve are: 1. The retractable oil outlet pipe can be used to lubricate the bent core. At the same time, the design of two duckbill valves increases the pressure in the oil tank when air is injected by the air cylinder, thereby exporting the internal lubricating oil from the retractable oil outlet pipe. This structure is simple, convenient and quick to operate, and can lubricate the bent core. 2. A telescopic oil outlet pipe is designed and installed inside the sealing rubber. The telescopic oil outlet pipe can slide inside the sealing rubber. When the telescopic oil outlet pipe is extended, pulling the telescopic oil outlet pipe will make the limiting plate inside the oil tank contact the mounting hole. At this time, the through groove passes through the L-shaped locking block. Rotating the telescopic oil outlet pipe will make the limiting plate press the sealing rubber, further sealing and preventing leakage. Attached Figure Description

[0012] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation are all within the protection scope of this utility model without creative effort.

[0013] Example: Please refer to Figures 1-7 As shown, this utility model provides a lubrication device for bending cores, such as... Figure 7 As shown, the bending core includes a core rod 16, on which a rotating core 15 is movably connected, and multiple rotating cores 15 are arranged so that the multiple rotating cores 15 can rotate.

[0014] like Figures 1-6 As shown, the front side of the oil tank 1 has a groove with a glass window 2 embedded inside. The oil level in the oil tank 1 can be observed through the glass window 2. The top surface of the oil tank 1 is provided with an oil filling port, and an oil filling cap 17 is provided on the oil filling port. A sealing element is provided between the oil filling cap 17 and the oil filling port. When the oil level is low, lubricating oil can be added through the oil filling port.

[0015] like Figures 1-6 As shown, a three-connector pipe 3 is installed in the middle of the top surface of the oil tank 1. The three-connector pipe 3 has a T-shaped structure, with two vertically arranged interfaces and one horizontally positioned interface. One vertical structure of the three-connector pipe 3 is inserted into the interior of the oil tank 1. Duckbill valves 4 are connected to the two vertical interfaces. The duckbill valves 4 are arranged in the same direction, with the duckbill facing downwards. An air cylinder 5 is connected to the horizontally positioned interface. The air cylinder 5 can be, but is not limited to, a syringe structure, which can inject air into the interior of the oil tank 1. The surface of the air cylinder 5 can be marked with graduations to inject a fixed amount of air and discharge a fixed amount of lubricating oil from the oil tank 1. A support base 7 is fixed to the top surface of the oil tank 1. Two clips 6 are fixed to the top surface of the support base 7 to fix the air cylinder 5. When the air cylinder 5 is used, the upper duckbill valve 4 closes and the lower duckbill valve 4 opens, thus injecting air into the oil tank 1. When the air cylinder 5 is filled with air, a negative pressure is generated inside the air cylinder 5. At this time, the lower duckbill valve 4 closes and the upper duckbill valve 4 opens, so that air can enter the interior of the air cylinder 5 without drawing out the air inside the oil tank 1, thus causing the oil in the telescopic oil pipe 11 to flow back.

[0016] like Figures 1-6As shown, a slope 8 is provided at the bottom edge of the oil tank 1. Two mounting holes 12 are symmetrically opened on the side of the slope 8. A sealing rubber 10 is provided inside the mounting hole 12. The telescopic oil outlet pipe 11 passes through the sealing rubber 10 and the sealing rubber 10 can play a sealing role to prevent leakage. L-shaped blocks 9 are provided on both sides of the slope 8. The L-shaped blocks 9 are fixed on the outside of the mounting hole 12. Two limiting plates 13 are fixed on the outside of the telescopic oil outlet pipe 11. The two limiting plates 13 are located inside and outside the oil tank 1, respectively. A through groove 14 is opened on the outside of the limiting plate 13. An inclined surface is provided on the contact surface between the limiting plate 13 and the L-shaped block 9. When the telescopic oil outlet pipe 11 is rotated, the limiting plate 13 will press the sealing rubber 10, thereby fixing the position of the telescopic oil outlet pipe 11 and further playing a sealing role. During lubrication, pull out the telescopic oil outlet pipe 11 so that the through groove 14 outside the inner limiting plate 13 passes through the L-shaped locking block 9, and the limiting plate 13 contacts the sealing rubber 10. Rotate the oil outlet pipe 11 so that the L-shaped locking block 9 presses the limiting plate 13 onto the sealing rubber 10, thereby fixing the oil outlet pipe 11 in the working state. After the oil is injected, rotate the oil outlet pipe 11 in the opposite direction so that the inner limiting plate 13 is no longer restricted. Push the oil outlet pipe 11 inward, and some oil will flow out from the outlet of the oil outlet pipe 11. It can be collected in a container or dripped onto the edge of the bending core. When the outer limiting plate 13 passes through the through groove 14, the limiting plate 13 contacts the outer side of the sealing rubber 10. Rotate the oil outlet pipe 11 so that the L-shaped locking block 9 presses the limiting plate 13, thereby fixing the position of the oil outlet pipe 11.
