Description

Technical Field

[0001] This utility model relates to the field of hydraulic machinery manufacturing technology, and in particular to a crimping machine mold base with self-lubricating function. Background Technology

[0002] In the industrial production field, crimping machines are a key piece of equipment widely used for crimping various high and low pressure oil pipes, air pipes, water pipes, cable joints, as well as automotive air conditioning pipes, power steering pipes, oil pipes, gasoline supply pipes, and even building accessories and daily hot water gas pipes. They play an indispensable role in industries such as vehicle manufacturing, construction machinery, hydraulic machinery, and welding and cutting equipment. Their working principle is to apply contraction force through a mold to firmly crimp the matching metal joint onto the connected pipe fittings, achieving a reliable connection and seal.

[0003] Traditional crimping machines rely on manual lubrication or lubricant injection machines for lubrication. Manual lubrication using an oil gun is cumbersome, and workers are prone to forgetting to lubricate, leading to untimely lubrication of parts, decreased equipment performance, and easy scratches between parts. While lubricant injection machines can lubricate at regular intervals, they require complex piping systems, which are not only difficult to install but also often result in over-lubrication, with lubricant overflow polluting the working environment. Furthermore, frequent inspection and maintenance of the piping are required, increasing management costs and workload.

[0004] Therefore, there is an urgent need to provide a self-lubricating crimping machine die base to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a crimping machine mold base with self-lubricating function.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a self-lubricating crimping machine mold base is provided, comprising multiple arc-shaped mold petals, the top of each of the multiple arc-shaped mold petals being provided with an oil injection port and a positioning hole; A self-lubricating liner is installed on the outer wall of each pair of arc-shaped mold segments. Two spring mounting seats and connecting segments are installed between each pair of arc-shaped mold segments. A second oil pipe is installed inside each connecting segment.

[0007] The present invention is further configured such that: multiple arc-shaped die petals are evenly distributed along the circumference of the crimping machine cavity, and a movement gap is reserved between the extrusion surfaces of adjacent arc-shaped die petals.

[0008] The above technical solutions can effectively prevent jamming or stuckness caused by mechanical interference during the contraction and opening of the mold petals, ensuring that each mold petal can complete the crimping action flexibly and smoothly. They can also buffer the impact force generated during the crimping moment through the gap, reducing mold petal wear. At the same time, they provide reasonable installation and working space for components such as self-lubricating liners, ultimately achieving stable operation of the mold base, improving crimping accuracy and equipment service life.

[0009] The present invention is further configured such that: each of the multiple arc-shaped mold segments has multiple lubricating oil channels and multiple self-lubricating graphite columns installed inside; each of the multiple arc-shaped mold segments has two guide keys installed on its inner wall; each of the multiple arc-shaped mold segments has a mold positioning hole near its center inside; and each of the multiple arc-shaped mold segments has multiple spring holes on its outer wall.

[0010] Through the above technical solution, multiple arc-shaped mold segments are precisely combined through mold positioning holes to form a mold cavity, meeting the processing requirements of different workpieces. During operation, lubricating oil is introduced through the lubrication channels, which, together with the self-lubricating graphite pillars, reduces friction between the mold segments themselves and other components, reduces wear, assists in heat dissipation, and ensures smooth operation. The guide keys on the inner wall ensure the accurate relative position of the mold segments and other components, improving the precision and reliability of the mold. The spring holes on the outer wall can be fitted with elastic elements to buffer the impact force on the mold segments during operation, helping the mold to open and close smoothly and reset. The cooperation of all components enables the arc-shaped mold segment 1 to be precisely formed, stably and durablely completing the mold processing task.

[0011] The present invention is further configured such that the self-lubricating liner is embedded in the outer wall of the arc-shaped mold piece via a guide key.

[0012] Through the above technical solution, the guide key provides precise and stable installation positioning for the self-lubricating liner, so that the liner fits tightly with the arc-shaped mold flap. Under the vibration and pressure generated by the high-intensity operation of the crimping machine, the self-lubricating liner is not easy to shift or fall off, effectively ensuring the reliability of the lubrication system.

[0013] The present invention is further configured such that: the self-lubricating liner has a plurality of embedded solid lubricating blocks regularly distributed inside.

[0014] Through the above technical solution, multiple embedded solid lubricating blocks can continuously and stably release lubricating substances to the moving friction surface of the mold base. While avoiding the drawbacks of traditional grease lubrication, such as easy contamination and the need for frequent maintenance, the lubrication area is fully covered through precise layout.

[0015] The present invention is further configured such that: the spring mounting seat is located within the movement gap between the extrusion surfaces of adjacent arc-shaped mold segments, and the shape of the spring mounting seat is adapted to the movement gap.

[0016] By placing the above-mentioned technical solution within the movement gap, a lubricating layer can be directly formed at the contact area when adjacent arc-shaped mold pieces move relative to each other. This effectively reduces the coefficient of friction between the arc-shaped mold pieces, reduces wear between components, avoids high temperatures and material loss caused by excessive friction, extends the service life of the arc-shaped mold pieces, and improves the overall durability of the mold base.

[0017] The beneficial effects of this utility model are as follows: 1. This utility model, by installing a self-lubricating liner, provides continuous and stable lubrication to the friction surface of the mold base under high load conditions, reducing component wear. The quick disassembly and assembly feature facilitates later maintenance and replacement of the liner, reducing equipment maintenance costs, thereby significantly improving the operating efficiency of the crimping machine, extending its overall service life, and providing reliable lubrication guarantee for pipe crimping operations.

[0018] 2. This utility model creates a closed, three-dimensional lubricating oil delivery network by opening lubricating oil channels inside the arc-shaped mold and connecting segments. Compared with traditional external application or drip lubrication methods, the lubricating oil can directly and quickly reach each key friction point under pressure through the lubricating oil channels inside the arc-shaped mold and connecting segments, reducing the loss and evaporation of lubricating oil during transmission and greatly improving the timeliness and effectiveness of lubrication.

[0021] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0022] Please see Figures 1-4A self-lubricating crimping machine die base includes multiple arc-shaped die segments 1, which are evenly distributed circumferentially along the crimping machine cavity. A movement gap is reserved between the extrusion surfaces of adjacent arc-shaped die segments 1, effectively preventing jamming or sticking due to mechanical interference during the contraction and opening of the die segments. This ensures that each die segment can complete the crimping action flexibly and smoothly. The gap also buffers the impact force generated during crimping, reducing die segment wear. Simultaneously, it provides reasonable installation and working space for components such as the self-lubricating liner 4, ultimately achieving stable operation of the die base, improving crimping accuracy and extending equipment lifespan. Each arc-shaped die segment 1 has multiple lubrication oil channels 11 and multiple self-lubricating graphite pillars 12 installed inside. Two guide keys 13 are installed on the inner walls of each arc-shaped die segment 1. Each of the arc-shaped mold segments 1 has a mold positioning hole 14 at its center. The outer walls of the multiple arc-shaped mold segments 1 have multiple spring holes 15. The multiple arc-shaped mold segments 1 are precisely combined through the mold positioning holes 14 to form a mold cavity, which meets the processing requirements of different workpieces. During operation, lubricating oil is introduced into the lubrication channel 11. With the help of the self-lubricating graphite column 12, the friction between the mold segment itself and other components is reduced, wear is reduced, heat dissipation is assisted, and smooth operation is ensured. The inner wall guide key 13 ensures that the relative position of the mold segment and other components is accurate, improving the mold precision and reliability. The outer wall spring hole 15 can be fitted with elastic elements to buffer the impact force on the mold segment during operation, helping the mold to open and close smoothly and reset. The cooperation of all components makes the arc-shaped mold segments 1 accurately formed, stable and durable to complete the mold processing task. The top of the multiple arc-shaped mold segments 1 is respectively provided with an oil injection port 2 and a positioning hole 3.

[0023] like Figure 1 and Figure 2As shown, a self-lubricating liner 4 is installed on the outer wall of each pair of arc-shaped mold petals 1. The self-lubricating liner 4 is embedded in the outer wall of the arc-shaped mold petal 1 via guide keys 13. The guide keys 13 provide precise and stable installation positioning for the self-lubricating liner 4, ensuring a tight fit between the liner and the arc-shaped mold petal 1. Under the vibration and pressure generated by the high-intensity operation of the crimping machine, the self-lubricating liner 4 is not prone to displacement or detachment, effectively ensuring the reliability of the lubrication system. The self-lubricating liner 4 has multiple embedded solid lubricating blocks regularly distributed inside. These embedded solid lubricating blocks can continuously and stably release lubricating substances to the moving friction surface of the mold base. While avoiding the drawbacks of traditional grease lubrication, such as easy contamination and frequent maintenance, the precise layout achieves the desired lubrication area. The system is fully covered, with two spring mounting seats 5 and connecting segments 6 installed between each pair of arc-shaped die segments 1. The spring mounting seats 5 are located in the movement gap between the extrusion surfaces of adjacent arc-shaped die segments 1, and their shape is adapted to the movement gap. By placing them in the movement gap, a lubricating layer can be directly formed at the contact area when adjacent arc-shaped die segments 1 move relative to each other, effectively reducing the coefficient of friction between the arc-shaped die segments 1, reducing wear between components, avoiding high temperature and material loss caused by excessive friction, extending the service life of the arc-shaped die segments 1, and improving the overall durability of the die base. Each connecting segment 6 has a module positioning hole 61 installed inside, and multiple mounting holes 62 are opened on the outer wall of each connecting segment 6.

[0024] In use, this utility model first precisely assembles multiple arc-shaped mold segments 1 into a mold cavity through the mold positioning hole 14 to meet the workpiece processing requirements. The oil injection port 2 can introduce lubricating oil into the lubrication channel 11. With the help of the self-lubricating graphite column 12 inside the arc-shaped mold segment 1, the self-lubricating liner 4 on the outer wall, and the spring mounting seat 5 in the movement gap between adjacent mold segments, the friction between the mold segments themselves and each other and with other components is reduced from multiple directions, reducing wear and assisting in heat dissipation. During the crimping process, the adjacent arc-shaped mold segments 1 flexibly contract and open along the circumference of the crimping machine cavity with the help of the reserved movement gap. The guide key 13 ensures the accurate relative position of the mold segments and the self-lubricating liner 4 and other components. The elastic element in the spring hole 15 buffers the impact force. The connecting segment 6 is assembled and positioned as a whole with the help of the module positioning hole 61, mounting hole 62 and other auxiliary mold bases. All components work together to make the mold segments complete the crimping action smoothly, stably realize the workpiece crimping processing, improve the crimping accuracy and the service life of the equipment.
