Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a self-lubricating precision stamping die. Background Art

[0002] A stamping die is a tool used to perform a stamping process on metal sheets, sheets, or strips. Typically consisting of an upper die and a lower die, a stamping die applies high pressure to the workpiece, forcing it into the desired shape between the dies. This process is commonly used to produce a variety of metal products, including automotive parts, electronic device housings, and household appliances.

[0003] When stamping products with a stamping die, if the product's precision requirements are relatively high, guide pins are added between the upper and lower dies. The guide pins can play the role of positioning the upper and lower dies. In the process of helping the upper and lower dies to position, the guide pins need to be kept lubricated. The lubrication of the guide pins requires constant application of lubricating oil to maintain lubrication. Therefore, the operation is cumbersome and the production efficiency is low.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution, which includes a lower mold, guide columns are provided on the four corners of the top of the lower mold, and an oil groove is provided at the bottom of each guide column. Several of the oil grooves are connected to each other, and an upper mold is provided between several of the guide columns. Sliding holes are provided on the four corners of the upper mold, and the guide columns are arranged in the sliding holes, and an oiling component is provided on each sliding hole.

[0006] As a preferred embodiment of the present invention, the oiling assembly includes a fixed cover arranged on the sliding hole, a fixed column is provided on the top surface of the fixed cover, the fixed column is inserted in the guide column, and the bottom outer side of the guide column is wrapped with oil-absorbing cotton.

[0007] As a preferred embodiment of the present invention, a plurality of mounting holes are provided on the side wall of the guide column, and a ball is provided in each mounting hole.

[0008] As a preferred embodiment of the present invention, an observation port communicating with the oil tank is provided on a corner of the lower mold, and transparent glass is provided in the observation port.

[0009] As a preferred embodiment of the present invention, an oil filling hole communicating with the oil filling tank is further provided on one side of the lower mold, and a sealing plug is detachably provided in the oil filling hole.

[0010] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0011] The utility model provides an oiling component in conjunction with a ball bearing, so that the upper die and the lower die can be self-lubricated, making the stamping process smoother, reducing energy loss, and helping to extend the service life of the die.

[0012] The utility model provides an observation port on the lower mold, which makes it convenient for operators to observe the storage amount of lubricating oil, thereby avoiding the occurrence of excessive oil filling or oil shortage. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0022] like Figure 1-Figure 4As shown, the utility model proposes a self-lubricating precision stamping die, which includes a lower die 2, guide columns 20 are provided on the four corners of the top of the lower die 2, and an oil groove 22 is provided at the bottom of each guide column 20, and several oil grooves 22 are communicated with each other. An upper die 1 is provided between several guide columns 20, and sliding holes 10 are provided on the four corners of the upper die 1. The guide columns 20 are arranged in the sliding holes 10, and an oiling component 3 is provided on each sliding hole 10.

[0023] like Figure 3 As shown, a plurality of mounting holes 21 are formed on the side wall of the guide post 20 , and a ball 23 is disposed in each mounting hole 21 .

[0024] like Figure 5 As shown, an observation port 24 communicating with the oil filling tank 22 is provided on one corner of the lower mold 2, and a transparent glass 25 is provided in the observation port 24; an oil filling hole 26 communicating with the oil filling tank 22 is also provided on one side of the lower mold 2, and a removable sealing plug 27 is provided in the oil filling hole 26.

[0025] like Figure 7 As shown, the oiling assembly 3 includes a fixed cover 30 arranged on the sliding hole 10, a fixed column 31 is provided on the top surface of the fixed cover 30, and the fixed column 31 is inserted into the guide column 20. The bottom outer side of the guide column 20 is wrapped with oil-absorbing cotton 32.

[0026] Before use, first remove the sealing plug 27 and inject lubricating oil into the oil tank 22 from the oil filling hole 26. Then observe the oil level through the observation port 24. When the oil is full, stop filling and finally replace the sealing plug 27.

[0027] During use, when the punching machine drives the upper mold 1 to press down, the fixed column 31 will be inserted into the oil tank 22, and then the oil-absorbing cotton 32 will absorb the lubricating oil. After the punching is completed, the punching machine drives the upper mold 1 to rise, and the fixed column 31 rises with it. While rising, the oil-absorbing cotton 32 contacts several balls 23 and applies lubricating oil to the surface of the balls 23. When the balls 23 roll, they contact the sliding holes 10, thereby realizing the self-lubricating function.

[0028] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention.
