Abstract

The utility model relates to a punching device of a cylindrical piece for processing two relative openings, which belongs to the technical field of a stamping die. The punching device comprises an upper convex die fixed on an upper fixed plate and a lower convex die fixed on a lower fixed plate, and the upper convex die is opposite to the lower convex die. A stripper is movably connected to the lower part of the upper fixed plate through screws, and a layer of polyurethane rubber is arranged between the stripper and the upper fixed plate. A hanging pillar is arranged between the upper convex die and the lower convex die, the hanging pillar is movably connected to a sliding pillar through a sliding sleeve, and a spring is arranged below the sliding sleeve. The upper part and the lower part of the hanging pillar are respectively provided with a concave die, and the two concave dies respectively correspond to the upper convex die and the lower convex die. The shape of the hanging pillar is matched with the processed cylindrical piece, thus the utility model can process two relative openings on the cylindrical piece simultaneously, the utility model has the characteristics of batch production with high precision, high pressing efficiency and high precision and the utility model is not needed to be repaired and ground.

Description

A kind of hole punched device of cylindrical member
(1) technical field
The utility model relates to the decompressor of two relative openings of a kind of cylindrical member processing, belongs to the technical field of diel.
(2) background technology
Usually can run into the situation in two relative holes of processing on cylindrical member aborning; generally bore process is adopted in this type of hole usually, also will increase the reconditioning operation after the boring, this processing method exists machining accuracy low; the shortcoming that production efficiency is low is not suitable for high accuracy and produces in batches.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of processing unit (plant) at two relative holes of processing on cylindrical member that is applicable to that high accuracy is produced in batches is provided, this device adopts a cover punch die, a punching press to finish, after finishing, punching press do not need reconditioning, simple in structure, cost is low, the productivity ratio height.
The utility model is realized by following measure:
The utility model discloses a kind of hole punched device of cylindrical member, comprise the last punch that is fixed on the upper mounted plate, be fixed on the lower punch of bottom plate, last punch is relative with lower punch, its special character is: the upper mounted plate below is connected with stripper by screw, and one deck polyurethane rubber is arranged between stripper and the upper mounted plate; One hanging pillar is arranged between last punch and the lower punch, and hanging pillar is movably connected on the traveller by sliding sleeve, and there is a spring below of sliding sleeve; The upper and lower part of hanging pillar has a die respectively, and two dies are corresponding with last punch and lower punch respectively, and the profile of hanging pillar matches with the processing cylindrical member.
The utility model is for fixing cylindrical member, and a location screw is installed in the outside of described hanging pillar.
The utility model is in order to make the hanging pillar fixed-site, and the top and bottom of described traveller are separately installed with stop.
The utility model is in order to make punch corresponding with the die position, and there is a guide pad in the described outside, lower end of going up punch.
This hole punched device mainly is made up of polyurethane rubber, stripper, dog screw, die, punch, stop, sliding sleeve, hanging pillar etc., wherein, stripper is connected by screw with cope match-plate pattern, polyurethane rubber is housed between the two, die is installed on the hanging pillar, hanging pillar and sliding sleeve interference fit are installed on the traveller, and hanging pillar can be realized sliding along traveller by the spring that is installed under it.Two stops are installed in respectively on traveller top and the fixed head, and dog screw is installed in the traveller left end, is used for locating.This hole punched device realizes punching out to two pairs of holes being working part with the hanging pillar that two dies are installed and two piercing punches, controls the stroke of hole punched device with two stops, and this hole punched device is installed on the forcing press, just can go out two pairs of holes simultaneously.
Therefore, the utility model energy is two relative holes of processing on cylindrical member simultaneously, and have high accuracy batch process, punching out efficient height, the high characteristics that do not need reconditioning that reach of precision.
