Description

Technical Field

[0001] The present application relates to the technical field of stamping equipment, and in particular to an oiling device for stamping. Background Art

[0002] During the metal stamping process, stamping oil has a significant impact on the deformation force consumption, the surface quality and internal quality of the metal workpiece, and the wear and tear of the tooling. During the stamping process, stamping equipment usually needs to spray stamping oil on the surface of the stamped parts to prevent cracking during the stamping process. Stamping oils mainly include mineral oils, volatile oils, boronized soap dry film, soap compounds, and other substances.

[0003] Stamping oil generally has excellent lubricity and extreme pressure properties, providing excellent protection for stamping dies. Before stamping a metal strip, stamping oil is traditionally sprayed on the upper and lower surfaces. To reduce oil waste, a manual application roller soaked in stamping oil is now used to apply it to the upper and lower surfaces.

[0004] However, during long-term stamping operations, the manual rolling and brushing stamping oil method has disadvantages such as high labor intensity and fatigue of operators and low stamping efficiency. Utility Model Content

[0005] In order to improve the situation where the workload of manual oiling is large and the efficiency of the stamping process is low, the present application provides an oiling device for stamping.

[0006] The present application provides a stamping oiling device, which adopts the following technical solution:

[0007] A stamping oiling device includes a support frame, the support frame being rotatably connected to a horizontally placed upper roller and a lower roller, the upper roller and the lower roller being parallel and stacked vertically, with a gap between the upper roller and the lower roller for a metal strip to pass through;

[0008] The surfaces of the upper roller and the lower roller are both provided with absorbent cotton, and the absorbent cotton covers the surfaces of the upper roller and the lower roller. The support frame is provided with an oil dripping pipe above the upper roller, and an oil dripping hole facing the upper roller is opened at the bottom of the oil dripping pipe. The support frame is provided with an oil tank below the lower roller, and part of the roller body of the lower roller is placed in the oil tank. The oil dripping pipe and the oil tank can both be connected to an external oil supply device.

[0009] By adopting the above technical solution, the stamping oil flows out from the oil dripping hole of the oil dripping tube and drips onto the absorbent cotton on the surface of the upper roller. The absorbent cotton can absorb a large amount of stamping oil due to its water absorbency. In this process, the absorbent cotton on the upper roller is gradually filled with stamping oil, and the roller body of the lower roller is partially placed in the oil tank. Stamping oil can be introduced into the oil tank, so that the absorbent cotton on the surface of the lower roller is immersed in the stamping oil during the rotation process, and the absorbent cotton on the lower roller is also filled with stamping oil. When the metal strip passes through the gap between the upper roller and the lower roller, the absorbent cotton evenly applies stamping oil to the upper and lower surfaces of the metal strip at the same time. This process does not require manual application of stamping oil, which greatly reduces the workload of manual oiling and effectively improves the overall efficiency of the stamping process.

[0010] Optionally, a limit seat is provided on the top of the support frame, and an oil supply hole is opened in the limit seat along its own length direction, and the oil supply hole is used to connect to an external oil supply device.

[0011] By adopting the above technical solution, since the through hole on the oil dripping tube is connected to the oil supply hole in the limit seat, stamping oil can be introduced into the oil dripping tube through the oil supply hole, and the stamping oil then flows out from the oil dripping hole of the oil dripping tube. At the same time, the limit seat also provides reliable support for the oil dripping tube, making the oil dripping tube more firmly fixed.

[0012] Optionally, a threaded section is provided on the outer tube wall of the oil drip tube near the bottom end, and the oil drip tube near the bottom end is threadedly connected to the limit seat through the threaded section.

[0013] By adopting the above technical solution, the oil dripping tube is threadedly connected to the limit seat through the threaded section near the bottom, and is slidingly connected to the limit seat at one end near the top. When it is necessary to adjust the flow rate of the oil dripping tube, external force can be applied to twist the oil dripping tube to move the oil dripping tube toward or away from the upper roller. During the movement of the oil dripping tube, the number of through holes connected to the oil supply holes increases or decreases to achieve adjustment of the amount of oil dripping, and the threaded connection between the bottom of the oil dripping tube and the limit seat can effectively reduce the leakage of stamping oil.

[0014] Optionally, the outer pipe wall of the oil drip pipe near the top end is provided with a threaded segment, the oil drip pipe near the top end is threadedly connected with the limiting seat through the threaded segment, the pipe body near the bottom end of the oil drip pipe is slidingly connected with the limiting seat, the through hole is provided in the pipe wall at the position of the threaded segment, a plurality of through holes are provided and are spaced apart along the length direction of the oil drip pipe, the limiting seat is provided with a sealing element at the sliding connection position with the oil drip pipe, the oil drip pipe penetrates through the sealing element, and the outer wall of the oil drip pipe abuts against the sealing element.

[0018] Optionally, the support frame is provided with a backflow pipe at the bottom, the backflow pipe is in communication with the oil tank, and a driving source is arranged on the backflow pipe.

[0019] By adopting the above technical scheme, the backflow pipe can be in communication with the externally connected oil supply device or directly in communication with the oil supply pipe, and the stamping oil in the oil tank can be backflowed to the oil supply device or the oil supply pipe through the driving source, so that the stamping oil can be recycled.

[0020] Optionally, a liquid level sensor is arranged on the inner wall of the support frame at the oil tank, and the liquid level sensor is used to monitor the liquid level height of the stamping oil in the oil tank in real time.

[0036] The following is combined with Figure 1-5 This application is described in further detail.

[0037] Example 1:

[0038] The present application discloses a stamping oiling device according to embodiment 1. Figure 1 and Figure 2 A stamping lubricating device includes a support frame 1, which is arranged between a stamping machine 2 and a feeding device 3. The support frame 1 can be fixed to the main body of the stamping machine 2 or the feeding device 3, or fixed to a workbench to provide reliable support for the support frame 1. The metal strip 31 passes from one end of the feeding device 3 through the support frame 1 and is then transported to the stamping machine 2 for the stamping operation.

[0039] The support frame 1 is placed vertically, and a support leg 11 is fixed at the bottom of the support frame 1. The number of the support legs 11 can be two, and the support legs 11 can provide support for the fixation of the support frame 1. The support frame 1 includes two vertical frames 12 and a horizontal frame 13. The horizontal frame 13 is located between the two vertical frames 12 and is vertically fixed to the bottom of the two vertical frames 12.

[0040] An upper roller 4 and a lower roller 5 are rotatably connected between the two vertical frames 12. Both rollers are positioned horizontally and parallel to each other. The upper roller 4's ends along its length are rotatably connected to opposing inner walls of the two vertical frames 12. Simultaneously, the lower roller 5's ends along its length are also rotatably connected to opposing inner walls of the two vertical frames 12, with the upper roller 4 positioned directly above the lower roller 5. A gap is left between the upper roller 4 and the lower roller 5, allowing the metal strip 31 to pass through. In other embodiments of the present application, the positions of the upper roller 4 and the lower roller 5 relative to the vertical frames 12 are adjustable, allowing the gap between them to be dynamically adjusted based on the thickness of the metal strip 31.

[0041] Reference Figure 2 and Figure 3A limit seat 6 is mounted on top of the vertical frame 12, perpendicular to the vertical frame 12. Both ends of the limit seat 6 are fixedly connected to the two vertical frames 12. A vertical oil dripping tube 7 is inserted through the limit seat 6. The dripping tube 7 is hollow and has an oil dripping hole 71 at the bottom, facing the upper roller 4. The number of oil dripping tubes 7 can be five, or more or less than five, as long as the number of oil dripping tubes 7 is sufficient to cover the upper roller 4 along its length.

[0042] An oil supply hole 61 is provided inside the limit seat 6 along its length, and the oil dripping pipes 7 are spaced apart along the direction in which the oil supply hole 61 is provided. An oil groove 14 with an upward opening is provided along the length of the cross frame 13, and part of the body of the lower roller 5 is placed in the oil groove 14. An oil delivery pipe 8 is fixed to one side of the limit seat 6. The oil delivery pipe 8 is connected to the oil supply hole 61 and the oil groove 14 respectively. The end of the oil delivery pipe 8 away from the limit seat 6 can be connected to an external oil supply device, which can deliver stamping oil to the oil dripping pipe 7 and the oil groove 14. A first adjustment control 81 is fixed to the pipe wall corresponding to the oil supply hole 61 and the oil groove 14. The first adjustment control 81 can be an electrically controlled valve. The first adjustment control 81 can be electrically connected to an external control unit, and the on-off of the stamping oil entering the oil supply hole 61 or the oil groove 14 can be dynamically controlled by the first adjustment control 81.

[0043] Reference Figure 2 and Figure 3 A return pipe 15 is fixed to the bottom of the cross frame 13. The return pipe 15 is connected to the inside of the oil tank 14. A driving source 16 is fixed to the return pipe 15. The driving source 16 can be an oil pump. The end of the return pipe 15 away from the cross frame 13 can be connected to an external oil supply device, so that the excess stamping oil in the oil tank 14 can be returned to the oil supply device; or the end of the return pipe 15 away from the cross frame 13 is connected to the oil pipe 8, so that the excess stamping oil in the oil tank 14 can be re-transported to achieve the recycling of the stamping oil. A liquid level sensor 17 is fixed to the inner wall of the oil tank 14 of the cross frame 13. The liquid level sensor 17 can be electrically connected to an external control unit. When the stamping oil level in the oil tank 14 reaches the installation height of the liquid level sensor 17, the liquid level sensor 17 can send a signal to the external control unit. At this time, the driving source 16 on the return pipe 15 works to discharge the excess stamping oil in the oil tank 14, reducing the overflow of the stamping oil.

[0044] A dripping pipe 62 is also provided on the side of the stopper 6 corresponding to the discharge of the metal strip 31. This dripping pipe 62 is fixed to the stopper 6 via a fixing base, with its opening facing downward toward the metal strip 31. A second control 10 is fixed to the dripping pipe 62. This second control 10 can be an electrically controlled valve, which controls the water output of the dripping pipe 62. The dripping pipe 62 can be connected to an external container or device containing saponified water, allowing the saponified water to drip onto the metal strip 31. This saponified water forms a highly absorbent and lubricating saponified layer on the surface of the metal strip 31, facilitating the smooth execution of subsequent stamping processes.

[0045] Reference Figure 3 and Figure 4 The outer tube wall of the oil dripping tube 7 near the bottom end is provided with a threaded section 72, and the position of the limit seat 6 corresponding to the threaded section 72 is provided with an internal thread, that is, the limit seat 6 is provided with an internal thread at a position corresponding to the oil dripping tube 7 and below the oil supply hole 61, so that the oil dripping tube 7 is threadedly connected to the limit seat 6 through the threaded section 72. The threaded connection can effectively reduce the leakage of stamping oil from the junction of the oil dripping tube 7 and the limit seat 6. The tube body of the oil dripping tube 7 away from the end of the upper roller 4 is slidably connected to the limit seat 6.

[0046] A plurality of through-holes 73 are formed through the wall of the oil dripping tube 7, corresponding to the threaded section 72. These through-holes 73 are spaced apart along the length of the oil dripping tube 7. Rotating the oil dripping tube 7 allows it to move toward or away from the upper roller 4. This movement in the position of the oil dripping tube 7 changes the number of through-holes 73 that connect to the oil supply holes 61. To adjust the oil dripping volume or dripping frequency of the oil dripping tube 7, external force can be applied to rotate the oil dripping tube 7. This allows the oil dripping volume or dripping frequency to be dynamically adjusted by adjusting the number of through-holes 73 that connect to the oil supply holes 61.

[0047] The surfaces of both the upper roller 4 and the lower roller 5 are covered with absorbent cotton 9, and the absorbent cotton 9 is distributed along the length of the upper roller 4 or the lower roller 5. The absorbent cotton 9 can rotate with the upper roller 4 or the lower roller 5. Due to its water-absorbing properties, the stamping oil drips from the oil dripping tube 7 onto the absorbent cotton 9 of the upper roller 4 and is absorbed by the absorbent cotton 9. The absorbent cotton 9 on the lower roller 5 can absorb the stamping oil from the oil tank 14. The absorbent cotton 9 can store a certain amount of stamping oil. When the metal strip 31 passes through the gap between the upper roller 4 and the lower roller 5, the absorbent cotton 9 can evenly apply the stamping oil to the upper and lower surfaces of the metal strip 31, effectively reducing the workload of manual oiling and greatly improving the overall efficiency of the stamping process.

[0048] The implementation principle of an oiling device for stamping in Example 1 of the present application is as follows: the oil dripping tube 7 is connected to the oil supply hole 61 through the through hole 73, so that the stamping oil entering from the oil delivery pipe 8 can enter the oil dripping tube 7 along the through hole 73 through the oil supply hole 61, and finally flow out from the oil dripping hole 71 at the bottom of the oil dripping tube 7 and drip onto the absorbent cotton 9 of the upper roller 4. At the same time, the absorbent cotton 9 on the lower roller 5 can be soaked in the oil tank 14 as the lower roller 5 rotates, so that when the metal strip 31 passes through the gap between the upper roller 4 and the lower roller 5, the upper and lower surfaces of the metal strip 31 are evenly coated with stamping oil. The oil dripping tube 7 can also be rotated to adjust the number of through holes 73 connected to the oil supply hole 61, thereby adjusting the oil dripping amount and oil dripping frequency of the oil dripping tube 7.

[0049] Example 2:

[0050] The difference between Example 2 and Example 1 is that: Figure 5 The outer tube wall of the oil dripping tube 7 near the top end is provided with a threaded section 72, and the position of the limiting seat 6 corresponding to the threaded section 72 is provided with an internal thread, that is, the limiting seat 6 is provided with an internal thread at a position corresponding to the oil dripping tube 7 and located above the oil supply hole 61, so that the oil dripping tube 7 is threadedly connected to the limiting seat 6 through the threaded section 72. The tube body of the oil dripping tube 7 near the bottom end is slidably connected to the limiting seat 6, and the through hole 73 corresponds to the tube wall provided at the position of the threaded section 72. Similarly, there are multiple through holes 73, which are spaced apart along the length of the oil dripping tube 7. The limiting seat 6 is embedded with a sealing member 63 at the position of the sliding connection with the oil dripping tube 7. The sealing member 63 can be a rubber sealing ring. The oil dripping tube 7 is passed through the sealing member 63. The inner wall of the sealing member 63 is tightly fitted with the outer wall of the oil dripping tube 7. The provision of the sealing member 63 can effectively enhance the sealing performance of the joint between the oil dripping tube 7 and the limiting seat 6.

[0051] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
