Special sealing piece punching machine capable of selecting punching number

Abstract

The invention discloses a special sealing piece punching machine capable of selecting the punching number. The special sealing piece punching machine comprises a bottom plate. Punching devices, first supporting rods and a limiting device are fixedly connected to the upper surface of the bottom plate. The first supporting rods are located between the punching devices and the limiting device. Each punching device comprises a first electric telescopic rod. The top end of each first electric telescopic rod is fixedly connected with a first connecting block. The front face of each first connecting block is movably connected with the front face of a lever through a first pin shaft. The front face of each lever is movably connected with the front face of a second connecting block through a second pin shaft. According to the special sealing piece punching machine capable of selecting the punching number, by means of the arrangement of the punching devices, the first electric telescopic rods are shortened, drill bits are elevated through the action of the levers, and therefore the usage number of the drill bits can be adjusted according to the number of holes needed by a sealing piece, accordingly, the punching number of the sealing piece can be controlled, and the functions of the sealing piece punching machine are diverse.

Description

technical field [0001] The invention relates to the technical field of sealing parts processing, in particular to a special punching machine for sealing parts which can select the number of holes to be punched. Background technique [0002] Seals are materials or parts that prevent fluid or solid particles from leaking from adjacent joint surfaces and prevent external impurities such as dust and moisture from invading the internal parts of the machine. During the manufacturing process of the seal, a certain part needs to be punched, so that when the seal is connected with other devices, bolts can be used to connect the seal. A punching machine is required for punching the seal. The seals currently on the market The hole punching machine has a fixed number of holes for the sealing parts, but the number of holes required for some sealing parts is different, so that some sealing parts cannot use this kind of punching machine, so that the function of the hole punching machine is...
