Description
Technical Field
The utility model relates to the field of stamping equipment, in particular to a punch structure.
Background
In the production of automobile parts and body structures, it is often necessary to form holes in the panels, and stamping is a method of forming the holes by high-speed blanking to form the desired product from the sheet metal. In the stamping process, the punch head needs to punch the plate at a high speed from top to bottom, then ascend, eject the scraps from the die and prepare for the next punching. Therefore, the punch needs to slide up and down in the die to realize continuous execution of the punching process. However, friction is generated due to relative sliding between the punch and the die, abrasion exists on the punch after long-time use, burrs are generated in punching, and the punch needs to be replaced periodically.
Disclosure of Invention
The utility model aims to provide a punch structure so as to solve the problems that the service life and the punching quality of a punch are influenced due to abrasion caused by sliding of the punch in a die.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a punch structure, includes cylindric punch body, punch body top is the link, and punch body bottom is the punching press end of step form, and annular oil filler groove has been seted up along circumference to punch body upper portion, and spiral form's oil distribution groove has been seted up along circumference on the punch body of oil filler groove below, oil distribution groove top and oil filler groove intercommunication, and the oil filler cavity has been seted up to the link, and the intercommunication has the oil filler hole between oil filler cavity and the oil filler groove.
Preferably, as an improvement, a threaded connection hole is formed in the middle of the top surface of the connection end, and the oiling cavity is located at the bottom end of the threaded connection hole.
Preferably, as an improvement, the oil holes are uniformly distributed in four along the circumferential direction of the punch body. The four oil filling holes can distribute lubricating oil more uniformly.
Preferably, as an improvement, an annular oil storage tank is formed in the lower portion of the punch body along the circumferential direction, and the bottom end of the oil distribution tank is communicated with the oil storage tank.
Preferably, as an improvement, a mounting bolt is radially connected to the punch body below the oil storage tank.
The principle and the advantages of the scheme are as follows: during practical application, lubricating oil is poured into an oil injection cavity of a punch body in the working process, the punch body is mounted on punching equipment through a threaded connection hole, the lubricating oil enters an oil distribution groove from the oil injection cavity through an oil injection hole, flows along the oil distribution groove and is stored in the oil distribution groove and the oil storage groove, lubricating oil can be continuously lubricated for the surface of the punch and the inner cavity of a die in the working process of the punch, a uniform oil film is formed on the surface of a working part of the punch body, friction between the punch and the die is reduced, abrasion of the punch is reduced, probability of burrs occurring in punching is reduced, and the service life of the punch can be prolonged by 5-10 times.

Detailed Description
The following is a further detailed description of the embodiments:
reference numerals in the drawings of the specification include: the device comprises a threaded connection hole 1, a punch body 2, an oil distribution groove 3, a punching end 4, an oil injection groove 5, an oil injection hole 6, an oil storage groove 7, a mounting bolt 8 and an oil injection cavity 9.
The embodiment is basically as shown in fig. 1 and 2: the utility model provides a drift structure, includes cylindric drift body 2, and drift body 2 top is the link, and threaded connection hole 1 has been seted up at the top surface middle part of link, combines the shown in fig. 3, has seted up notes oil pocket 9 in the drift body 2 of threaded connection hole 1 bottom. Annular oil injection groove 5 has been seted up along circumference on drift body 2 upper portion, and spiral form oil distribution groove 3 has been seted up along circumference on the drift body 2 of oil injection groove 5 below, and oil distribution groove 3 is along anticlockwise spiral downwardly distributed, and oil distribution groove 3 top and oil injection groove 5 intercommunication have oil filler point 6 with the intercommunication between oil filler point 5 and the oil injection cavity 9, and oil filler point 6 has four along drift body 2 circumference evenly distributed. An annular oil storage tank 7 is formed in the lower portion of the punch body 2 along the circumferential direction, and the bottom end of the oil distribution tank 3 is communicated with the oil storage tank 7. The oil injection groove 5, the oil distribution groove 3 and the oil storage groove 7 are all arc grooves, so that the flow of lubricating oil is facilitated. A mounting bolt 8 is radially connected to the punch body 2 below the oil storage tank 7. The bottom end of the punch body 2 is a stepped punching end 4 with a reduced diameter, and an arc transition surface is arranged between the punching end 4 and the middle part of the punch body 2.
The specific implementation process is as follows: lubricating oil is poured into an oiling cavity 9 of the punch body 2 in the working process, the punch body 2 is arranged on punching equipment through a threaded connection hole 1, the lubricating oil enters an oil distribution groove 3 from the oiling cavity 9 through an oil injection hole 6, flows along the oil distribution groove 3 and is stored in the oil distribution groove 3 and an oil storage groove 7, lubricating oil can continuously lubricate the surface of the punch and the inner cavity of a die in the working process of the punch, a uniform oil film is formed on the surface of the working position of the punch body 2, friction between the punch and the die is reduced, abrasion of the punch is reduced, probability of burrs occurring in punching is reduced, and the service life of the punch can be prolonged by 5-10 times.
