Description
Technical field
The present invention relates to a kind of punching cutter structures, are exclusively used in processing rushing for soft smooth type surface parts more particularly, to a kind of
Cutter.
Background technique
Currently, for automobile interior decoration acoustics part, PET felt is high with its acoustic absorptivity, heat-insulated and heat-resisting quantity is excellent and
Nontoxic characteristic is widely used.The part smooth for some type faces, the technique used is directly is punched into stamping knife come such as
Fig. 1 so, simultaneously because PET felt itself is soft, during processing, when the edge of a knife is punched downwards, PET felt is compressed,
Part edge will appear the circular arc being recessed inwardly after being punched in this way, adverse effect be caused for the appearance of part, such as Fig. 2 institute
Show.
Summary of the invention
It is an object of the present invention to overcome the above-mentioned drawbacks of the prior art and provide one kind be exclusively used in processing it is soft
The punching knife system of the smooth type surface parts of matter.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of punching knife system for being exclusively used in processing soft smooth type surface parts including tool apron and is mounted on rushing on tool apron
Cutting knife unit, the punching cutter unit are made of the punching cutter head of two spaced and parallel settings, the punching cutter head direction
In vertical planar, the corresponding other side is in be inclined outwardly and the arc of rounding off for the side of soft smooth type surface parts to be processed
Planar.
Preferably, the edge of a knife of described two punching cutter heads flushes in the horizontal plane.
Preferably, the spacing of described two punching cutter heads is 1-3mm.Spacing is excessive, cannot be formed between two knives mutually
Abutment action, part edge will appear the circular arc being recessed inwardly after punching, cause adverse effect for the appearance of part；Between
Away from too small, stamping knife machining accuracy increases, difficult to install, increased costs between double-pole.
Preferably, the tool apron includes the fixation tool post being located above, and setting is on fixed tool post and can
The two movable tool-holder bodies moved along its surface are fixedly installed with the punching on described two movable tool-holder bodies respectively
Cutter head, and two gaps for being punched cutter head are adjusted by the gap of two movable tool-holder bodies of adjusting.
It is furthermore preferred that the fixation tool post is equipped with sliding slot in the horizontal direction, the movable tool-holder body is set
It sets in the sliding slot, is additionally provided with the regulating part for driving the movable tool-holder body to move along the chute on fixed tool post.
Even more preferably, the regulating part includes the adjusting substrate for being vertically disposed on sliding slot both ends, and
It is thread through the adjusting substrate and the along the chute adjusting screw rod in direction, one end rotation of the adjusting screw rod resists described removable
Tool post, the other end is as adjustable side.
Further it is furthermore preferred that being additionally provided with the pilot hole in direction along the chute on the adjusting substrate, led across described
Direction along the chute is additionally provided with to hole and connects the guide rod of the movable tool-holder body.
Further it is furthermore preferred that the adjusting screw rod be respectively equipped on two side positions for adjusting substrate it is matched
Fastening nut.The quantity of fastening nut can be according to requiring to be adjusted.
Compared with prior art, the invention has the following advantages that
(1) the punching cutter head of punching cutter unit of the invention by two spaced and parallel settings of setting, i.e., a newly-increased punching
Cutter head, in this way, being increased newly when punching cutter unit of the invention is used to be punched the soft smooth type surface parts such as PET felt etc
Punching cutter head can resist the part that PET felt is heaved so that originally removed region obtained effective compensation, so that originally
The recess circular arc sector that part edge occurs is smooth, meets the appearance requirement of part.When hilted broadsword punching, perpendicular to stamping knife table top
Soft material during compression, can cause soft material that need to be punched among face bulging into a prominent circular arc state, but
It is the stamping knife edge of a knife always perpendicular to punching table top, during stamping knife is punched downlink, always perpendicular to the edge of a knife of punching table top
Circular arc outstanding can be punched out, i.e., will be compressed material outstanding and cut off, and be recessed so as to cause soft material intermediate region,
Size and appearance requirement are not met；When double-pole is punched together, perpendicular to the soft material for being punched table top in pressurized process, draw
The bulging of face centre need to be punched at a prominent circular arc state, but when the second punching cutter head downlink by playing soft material, can be squeezed prominent
The soft material of circular arc out, soft material protrusion are sprung back after being pressurized towards the first punching cutter head direction, and soft material is made to need to rush
Section remains perpendicular to punching table top, so that it is guaranteed that soft material smooth, the no recess that need to be punched face intermediate region after punching,
Size and appearance requirement are met the requirements.
(2) by the way that tool apron is divided into fixed tool post and movable tool-holder body, and two are adjusted by movable tool-holder body
The spacing of a punching cutter head, makes it possible to the punching for adapting to the soft smooth part of different pliabilitys.
(3) step-less adjustment may be implemented in the adjusting that spacing is carried out by adjusting screw rod, and by setting adjusting screw rod
Flight pitch can very easily adjust degree of regulation.
(4) adjusting screw rod cooperates it that can easily realize movable tool-holder in the fastening nut for adjusting the setting of substrate two sides
Positioning between body, to improve the regulating effect of spacing between punching cutter head.
