[0006] As a further improved technical solution, the utility model provides a lubricating mechanism for an aluminum template punching device, wherein the inlet end of the oil inlet branch pipe has a threaded section, and the lubricating mechanism for the aluminum template punching device also has an oil seepage screw connected to the inlet end of the oil inlet branch pipe, and the oil seepage screw has an oil seepage hole.

[0007] As a further improved technical solution, the utility model provides a lubricating mechanism for an aluminum template punching device, wherein the tops of the oil inlet branch pipe and the oil inlet groove have a cover plate detachably connected to the punching fixed die.

[0008] In the absence of conflict, the aforementioned improved technical solutions can be implemented individually or in combination.

[0009] The utility model provides a technical solution in which an oil film is formed between the annular oil groove and the punch needle. When the punch needle passes through the oil film, the lubricating oil is brought into the punch needle guide sleeve, so that there is a good lubrication effect between the punch needle and the punch needle guide sleeve, thereby improving the lubrication of the punch needle. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the present application. The illustrative embodiments of the present invention and their descriptions are used to explain the present invention, but do not constitute an improper limitation on the present invention. In the accompanying drawings:

[0014] Figure 4 yes Figure 1 Enlarged view of point C in the figure. DETAILED DESCRIPTION

[0015] The specific implementation of the utility model is further described in detail below with reference to the accompanying drawings.

[0016] like Figures 1 to 4The lubricating mechanism of the aluminum template punching device shown comprises an oil pump 1, a control valve 2 connected to the outlet of the oil pump 1 through a pipeline; the aluminum template punching device has a punching fixed die 3, a punching needle guide sleeve 4 arranged on the punching fixed die 3, the punching needle guide sleeve 4 has an annular oil groove 5, the punching fixed die 3 has an oil inlet branch pipe 6 and an oil return branch pipe 7 connected to the annular oil groove 5, an oil inlet groove 8 connected to the outlet of the control valve 2 and connected to the oil inlet branch pipe 6 through a pipeline, and an oil return groove 9 connected to the oil return branch pipe 7. The inlet end of the oil inlet branch pipe 6 has a threaded section, and the lubricating mechanism of the aluminum template punching device also has an oil seepage screw 10 connected to the inlet end of the oil inlet branch pipe 6, and the oil seepage screw 10 has an oil seepage hole. The top of the oil inlet branch pipe 6 and the oil inlet groove 8 has a cover plate 11 detachably connected to the punching fixed die 3. The provision of the oil seepage screw 10 is conducive to controlling the oil inlet amount of the oil inlet branch pipe 6 and reducing the probability of oil circuit blockage.

[0017] During operation, the lubricating oil delivered by the oil pump 1 enters the oil inlet groove 8 after passing through the control valve 2, and overflows from the oil inlet groove 8 to each oil inlet branch pipe 6. The lubricating oil descends along the oil inlet branch pipe 6 and enters the annular oil groove 5. There is a gap between the annular oil groove 5 and the punch needle. Because the lubricating oil has a certain viscosity, an oil film is formed between the annular oil groove 5 and the punch needle. When the punch needle passes through the oil film, the lubricating oil is brought into the punch needle guide sleeve 4, so that there is a good lubrication effect between the punch needle and the punch needle guide sleeve 4. The oil film in the annular oil groove 5 slowly flows into the oil return branch pipe 7, enters the oil return groove 9 through the oil return branch pipe 7, and is injected into the oil return tank from the oil return groove 9.

[0018] The utility model provides a technical solution in which an oil film is formed between the annular oil groove 5 and the punch needle. When the punch needle passes through the oil film, the lubricating oil is brought into the punch needle guide sleeve 4, so that there is a good lubrication effect between the punch needle and the punch needle guide sleeve 4, thereby improving the lubrication of the punch needle.

[0019] The above description is only the preferred embodiment of the utility model, and does not limit the utility model in any way. For those skilled in the art, the utility model can be modified and changed in various ways. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
