Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, specifically to a hardware stamping die guide mechanism with a buffer structure. Background Technology

[0002] Stamping dies are special process equipment used in cold stamping to process materials (metal or non-metal) into parts (or semi-finished products). They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses dies mounted on a press to apply pressure to materials at room temperature, causing them to separate or plastically deform, thereby obtaining the desired parts.

[0003] Chinese patent application CN201720247105.6 discloses a guiding mechanism for a metal stamping die, including an upper die, a fixed sleeve, a guide post, and a lower limit block. The upper die has a sealing plug at its upper end, which is connected to an oil inlet channel. The fixed sleeve is connected to the upper die via a sleeve fixing seat. The guide post is located inside the upper die. A compression spring is located at the lower end of the lower limit block, and a fixing rod is installed inside the compression spring. The fixing rod is connected to a fixed base plate via a guide post fixing seat, and a fixing pin is located inside the guide post fixing seat. This device effectively prevents the guiding mechanism from becoming stuck or jammed after mass production, thus ensuring the quality of die manufacturing and preventing damage to the die due to excessive pressure, thereby extending the die's service life. It also prevents material loss and waste, and the overall structure is stable and durable.

[0004] However, the following drawbacks still exist:

[0005] When there is too little lubricating oil, the lubrication effect is limited; when there is too much lubricating oil, the lubricating oil cannot be recycled, indicating room for improvement. Utility Model Content

[0009] The above-mentioned metal stamping die guide mechanism with buffer structure includes: an oil baffle plate fixedly connected to the outer position of the top of the lower base plate, and an oil storage cavity provided on the lower base plate.

[0027] Example

[0028] This embodiment provides a guide mechanism for a metal stamping die with a buffer structure, such as... Figures 1-4 As shown, it includes: a lower base plate 100 and an upper top plate 120. The upper top plate 120 is located directly above the lower base plate 100. A metal stamping die guide lubrication mechanism 200 is provided between the lower base plate 100 and the upper top plate 120. The metal stamping die guide lubrication mechanism 200 includes a piston rod 210 fixedly connected to the top of the lower base plate 100. A telescopic rod 211 is slidably connected to the top of the piston rod 210. The telescopic rod 211 is fixedly connected to the bottom of the upper top plate 120. An oil inlet pipe 221 and an oil outlet pipe 222 are fixedly connected to the surface of the piston rod 210.

[0029] The above-mentioned technical solution provides a guide mechanism for a metal stamping die with a buffer structure, which includes a guide lubrication mechanism 200. When the upper top plate 120 drives the punch 121 to move up and down, the piston rod 210 draws lubricating oil through the oil inlet pipe 221, sends the lubricating oil to the connecting plate 220 through the oil outlet pipe 222, and finally sprays it out from the oil outlet hole 223 to lubricate the telescopic rod 211 and the piston rod 210. The lubricating oil is recovered through the oil baffle plate 225 to achieve sufficient lubrication and avoid waste.

[0030] To collect lubricating oil, an oil baffle 225 is fixedly connected to the outer part of the top of the lower base plate 100, and an oil storage chamber 226 is provided on the lower base plate 100. The lubricating oil is placed in the oil storage chamber 226.

[0031] To ensure that the oil inlet pipe 221 can draw lubricating oil from the oil storage chamber 226, the height of the oil inlet pipe 221 is lower than the height of the oil baffle 225, and one end of the oil inlet pipe 221 is fixedly connected to a filter plate 224. The filter plate 224 filters the lubricating oil in the oil storage chamber 226, removing impurities.

[0032] To ensure even flow of lubricating oil, one end of the oil outlet pipe 222 is fixedly connected to a connecting plate 220, which is fixedly connected to the top of the telescopic rod 211. An oil outlet hole 223 is provided at the bottom of the connecting plate 220. The oil outlet pipe 222 delivers lubricating oil into the connecting plate 220, and finally sprays it out from the oil outlet hole 223, thus fully lubricating the piston rod 210, the telescopic rod 211, and the buffer spring 212.

[0033] In order to ensure that the lubricating oil is sprayed evenly, the oil outlet 223 is arranged in a ring at the bottom of the connecting plate 220, and the oil outlet 223 is oriented towards the buffer spring 212 and the telescopic rod 211.

[0034] For stamping hardware parts, a die 110 is fixedly connected to the top of the lower base plate 100, and a punch 121 corresponding to the die 110 is fixedly connected to the bottom of the upper top plate 120. The upper top plate 120 is fixedly connected to the telescopic end of a hydraulic cylinder, and the punch 121 is moved toward the die 110 by the hydraulic cylinder to stamp the hardware parts.

[0035] In order to replace the punch 121 and stamp different hardware, the upper plate 120 is provided with a through hole corresponding to the telescopic rod 211, and a locking nut is threadedly connected to the upper part of the surface of the telescopic rod 211.

[0036] In summary, the metal stamping die guide mechanism with buffer structure provided in this embodiment has the following advantages: a metal stamping die guide lubrication mechanism 200 is provided. When the upper top plate 120 drives the punch 121 to move up and down, the piston rod 210 draws lubricating oil through the oil inlet pipe 221, sends the lubricating oil to the connecting plate 220 through the oil outlet pipe 222, and finally sprays it out from the oil outlet hole 223 to lubricate the telescopic rod 211 and the piston rod 210. The lubricating oil is recovered through the oil baffle plate 225, so as to achieve sufficient lubrication and avoid waste.

[0037] In use, the upper ejector plate 120 drives the punch 121 to move toward the die 110 to stamp the hardware. When the upper ejector plate 120 moves downward, it presses the connecting plate 220, causing the telescopic rod 211 to move toward the piston rod 210, squeezing out the lubricant in the piston rod 210. The lubricating oil is sent into the connecting plate 220 through the oil outlet pipe 222 and finally sprayed out from the oil outlet hole 223 to lubricate the telescopic rod 211, the piston rod 210 and the buffer spring 212. The lubricating oil flows into the oil storage chamber 226 for recycling. After stamping is completed, the punch 121 moves upward. At this time, the telescopic rod 211 drives the piston in the piston rod 210 to move upward, drawing the lubricating oil in the oil storage chamber 226 into the piston rod 210, and the cycle repeats.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
