Description

Technical Field

[0001] This utility model relates to the field of stretching die technology, specifically to a stainless steel stretching die with lubrication. Background Technology

[0002] This utility model relates to the field of stainless steel stretch forming die technology, specifically a lubricated stainless steel stretch forming die. In the stretch forming process of stainless steel sheets, the lubrication effect of the die directly affects the forming quality of the workpiece and the service life of the die. Currently, traditional stainless steel stretch forming dies typically use manual application of lubricating oil for lubrication. This method has significant drawbacks: firstly, manual application makes it difficult to ensure the uniformity of the lubricating oil, easily leading to insufficient or excessive lubrication in certain areas of the die, resulting in scratches on the workpiece surface and deviations in forming accuracy; secondly, manual operation is inefficient, requiring frequent shutdowns for oil replenishment, severely impacting production rhythm and failing to meet the needs of large-scale continuous industrial production.

[0003] While some automated lubrication structures exist in existing technologies, most suffer from complex structures and high maintenance costs. For example, some molds use fixed oil nozzles or drip devices for lubrication. Although this achieves a certain degree of automation, the nozzles are prone to clogging, and the fixed lubrication position cannot adapt to positional deviations caused by mold deformation or vibration during operation, resulting in low lubrication reliability. Furthermore, traditional lubrication structures often lack efficient storage and continuous supply designs for lubricating oil, requiring frequent replacement of the oil storage device and increasing the labor intensity of workers.

[0004] To address the aforementioned issues, there is an urgent need to design a lubricated stainless steel stretch forming die to solve problems such as low lubrication efficiency, poor reliability, and frequent manual intervention in existing technologies, thereby improving the quality and production efficiency of stainless steel stretch forming. Summary of the Invention

[0005] The purpose of this invention is to provide a lubricated stainless steel stretch forming die to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A lubricated stainless steel stretch forming die includes an equipment mounting frame. The equipment mounting frame has an upper pressure plate and a bearing plate arranged from top to bottom inside. The outer wall of the bearing plate is provided with a positioning ring. The upper surface of the positioning ring is provided with a lubricating oil application component for lubricating the upper pressure plate and the bearing plate.

[0008] The lubricating oil application assembly includes a support rod, with an upper application plate and a lower application plate movably sleeved on the outer wall of the support rod. The upper surface of the upper application plate is movably connected to the bottom surface of the upper pressure template, and the upper surface of the pressure template is movably connected to the bottom surface of the lower application plate. An installation gear is fixedly connected to the bottom end of the support rod, and an auxiliary gear meshes with the outer wall of the installation gear.

[0009] The lubricating oil application assembly also includes an oil supply assembly for supplying lubricating oil to the upper and lower application plates.

[0010] A further improvement of this utility model is that both the mounting gear and the auxiliary gear are rotatably connected to the upper surface of the positioning ring.

[0011] A further improvement of this utility model is that an adjustable handle is fixedly connected to the top of the mounting gear.

[0012] A further improvement of this utility model is that: a spring is sleeved on the outer wall of the support rod near the bottom end, the top end of the spring abuts against the bottom surface of the lower coating plate, and a sliding groove is provided on the outer wall of the support rod.

[0013] A further improvement of this utility model is that a receiving sleeve fitted onto the outer wall of the support rod is provided between the upper coating plate and the lower coating plate.

[0014] A further improvement of the present invention is that the oil supply assembly includes an oil delivery pipe, the upper coating plate includes an oil box, and the oil box is fixedly connected to one end of the oil delivery pipe.

[0015] A further improvement of the present invention is that an oil pump is fixedly connected to the tail end of the oil pipeline, and an oil pump is fixedly connected to the oil inlet end of the oil pump.

[0016] A further improvement of this utility model is that: an installation plate is fixedly connected to the upper surface of the oil box, a sponge strip is fixedly connected to the top of the installation plate, an arc-shaped permanent magnet block is fixedly connected to the side of the installation plate, a collar is fixedly connected to one end of the installation plate, and a slider is fixedly connected to the inner wall of the collar.

[0017] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:

[0018] This invention provides a lubricated stainless steel stretch forming die. By incorporating an auxiliary gear that meshes with the mounting gear, rotating the auxiliary gear drives a support rod to rotate via gear transmission. This causes the upper and lower coating plates, movably sleeved on the support rod, to apply lubricant to the bottom surface of the upper pressure plate and the upper surface of the bearing plate, respectively. This structure eliminates the need for manual application, achieving automated and uniform application of lubricant. It avoids uneven lubrication caused by manual operation, significantly improving the lubrication effect on the die surface during stainless steel stretch forming, thereby enhancing the workpiece forming quality.

[0019] This invention provides a lubricated stainless steel stretch forming die. A spring sleeved near the bottom outer wall of the support rod abuts against the lower coating plate, providing the lower coating plate with elastic movement space. This allows it to adapt to changes in the position of the pressure-bearing template, ensuring a tight fit with the template surface throughout the die's operation and preventing lubrication failure due to mold vibration or positional deviation. Simultaneously, the receiving sleeve between the upper and lower coating plates, through the cooperation of a slider and a support rod groove, provides stable guiding support for the coating plates, reducing wobbling during rotation and further ensuring the reliability and consistency of lubricant application.

[0020] This invention provides a lubricated stainless steel stretch forming die. The oil supply assembly draws lubricating oil through an oil pump and a suction pipe, then delivers it to the oil box on the upper coating plate via an oil delivery pipe. A sponge strip on the mounting plate absorbs the lubricating oil and evenly applies it to the die surface during rotation. This design achieves continuous lubrication and efficient application, avoiding the intermittent defects of traditional manual oil replenishment and reducing downtime for maintenance. Furthermore, the symmetrically distributed and independently movable upper and lower coating plates allow for simultaneous lubrication of both the upper and lower die plates, further improving the efficiency of die lubrication and meeting the needs of continuous industrial production.

[0038] The working principle of this lubricated stainless steel stretch forming die will be explained in detail below.

[0039] like Figure 1-4 As shown, this utility model relates to a lubricated stainless steel stretch forming die, the working principle of which is as follows:

[0040] I. Overall Structure and Connections

[0041] The equipment mounting frame 1 has an upper pressure template 2 and a pressure-bearing template 3 arranged from top to bottom inside. The outer wall of the pressure-bearing template 3 is provided with a positioning ring, and a lubricating oil application component 4 is installed on the upper surface of the positioning ring. This component includes a support rod 10, whose outer wall is movably sleeved with an upper application plate 5 and a lower application plate 6. The upper surface of the upper application plate 5 is movably connected to the bottom surface of the upper pressure template 2, and the bottom surface of the lower application plate 6 is movably connected to the upper surface of the pressure-bearing template 3. A mounting gear 11 is fixedly connected to the bottom end of the support rod 10. The mounting gear 11 meshes with an auxiliary gear 12, and both are rotatably connected to the upper surface of the positioning ring. In addition, a spring 15 is sleeved on the outer wall of the support rod 10 near the bottom end, and its top end abuts against the bottom surface of the lower application plate 6. A receiving sleeve 7 is provided between the upper application plate 5 and the lower application plate 6, which is sleeved on the outer wall of the support rod 10. The oil supply component includes an oil supply pipe 8, an oil pump 9, etc., for supplying lubricating oil to the upper and lower application plates.

[0042] II. Principle of Lubricant Application

[0043] When the mold needs lubrication, the auxiliary gear 12 is rotated. Since the mounting gear 11 meshes with the auxiliary gear 12, the mounting gear 11 rotates accordingly, thereby driving the support rod 10 to rotate. The upper coating plate 5 and the lower coating plate 6 are movably sleeved on the support rod 10. Through the cooperation of the slider and the groove, they can only move up and down on the support rod 10. When the support rod 10 rotates, both plates rotate with it. The upper coating plate 5 is movably connected to the bottom surface of the upper pressure template 2, and the lower coating plate 6 is movably connected to the upper surface of the pressure template 3. Therefore, during rotation, the upper coating plate 5 and the lower coating plate 6 will respectively coat the bottom surface of the upper pressure template 2 and the upper surface of the pressure template 3, achieving uniform application of lubricating oil. The spring 15 provides the lower coating plate 6 with a certain elastic range of motion on the support rod 10, allowing it to better adapt to changes in the position of the pressure template 3 and ensuring the coating effect. The receiving sleeve 7 provides support and guidance for the upper and lower coating plates, ensuring their stable movement on the support rod 10.

[0044] III. Working Principle of the Oil Supply Component

[0045] When the oil supply assembly is working, the oil pump 9 starts, drawing lubricating oil from the external oil storage device through the oil extraction pipe 14, and delivering it to the oil box 16 of the upper coating plate 5 via the oil delivery pipe 8 hose. A sponge strip 18 is fixedly connected to the top of the mounting plate 17 on the upper surface of the oil box 16. The sponge strip 18 absorbs the lubricating oil in the oil box 16. When the upper coating plate 5, which is movably connected to the bottom surface of the upper pressure plate 2, rotates with the support rod 10, the sponge strip 18 evenly applies lubricating oil to the bottom surface of the upper pressure plate 2. Similarly, although the oil box structure of the lower coating plate 6 is not explicitly mentioned, it can be inferred that the oil supply assembly also provides lubricating oil to the lower coating plate 6, allowing it to lubricate the upper surface of the pressure plate 3 during rotation. The arc-shaped permanent magnet block 19 and the collar 20, among other structures, may play an auxiliary role in installation or positioning, ensuring stable connection and normal operation of each component.

[0046] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
