Abstract
The invention discloses an up-down semi-cutting technology for decorative strips and a die. The up-down semi-cutting technology comprises the steps that firstly, an upper tearing female die and an upper tearing male die are pulled open, and a workpiece to be machined is connected to an upper tearing male die fixing block in a sleeving mode; secondly, a motor is used to drive a stripping dowel bar to rotate clockwise so as to drive the upper tearing female die to press downward, and the upper surface of the workpiece is semi-cut under the stress action between the upper tearing female die and the upper tearing male die to form the grinding roller angle R; thirdly, the stripping dowel bar is rotated counterclockwise, the upper tearing female die is pulled upward through a stripping block, and the workpiece is taken out and fixed to a lower tearing male die fixing block between a lower tearing male die and a lower tearing female die; and finally, the motor is used to drive the stripping dowel bar to drive the lower tearing male die to press downward, the lower surface of the workpiece is semi-cut under the clamping force action between the lower tearing male die and the lower tearing female die to form the grinding roller angle R, and manufacturing is completed. According to the up-down semi-cutting technology for the decorative strips and the die, the procedures of secondary die machining needed for the angle R and the planeness of products are omitted.
Description
Technical field
The present invention relates to ornamental strip technical field is and in particular to a kind of ornamental strip half cutting process and mould up and down.
Background technology
Ornamental strip is made using pvc material, according to mantle different colours need carry out the process of decorative effect,
Weatherability is strong, will never change colour, and only gently need to be polished with fine sandpaper after scratching can be bright such as new.It is mainly used on automobile
Side Protector panel, increased the aesthetic feeling of vehicle body side, is identical with vehicle body radian, durable is indeformable.Meanwhile, to car
The body paint easily colliding with during door trip provides effective protection.Present processing existing technique one kind to ornamental strip is punching
Pressure material, this mode flatness is difficult to ensure that, also blanking connects knife technical gaps, and burr face needs secondary mould chamfering to realize
Lower edges R angle；Existing another kind technique be monolateral tear material mode, product is directly partly torn material, and this mode can ensure that flat
Face degree, but burr face is also required to secondary mould chamfering and realizes lower edges R angle.
Content of the invention
For problem above, the invention provides a kind of ornamental strip half cutting process and mould up and down, first that product is up smart
Hemisection, makes the top edge of product produce grinding roller R angle；Again by product down smart hemisection, product is allowed to utilize material during down
The chucking power of material makes the lower surface of product also produce grinding roller R, thus reaching the appearance requirement of product, solves product R angle peace
Face degree needs the operation of secondary mould processing, convenient production process operation, and cost is relatively low, can be with effectively solving background technology
Problem.
To achieve these goals, the technical solution used in the present invention is as follows：A kind of ornamental strip half cutting process up and down, including
Following steps：
S1, workpiece are fixed：By on tear die and above tear punch and pull open, workpiece to be processed is connected on and tears punch fixed block
On；
S2, the hemisection of upper essence：After workpiece fixes, take off material dowel steel using motor-driven, de- material dowel steel rotates clockwise, will
Die is torn on drive push, by above tear die and on tear the effect of pressure between punch, the upper surface of workpiece is carried out hemisection,
Form grinding roller R angle；
S3, the demoulding are fixed again：After the completion of the hemisection of upper essence, rotate counterclockwise de- material dowel steel, tear die by pulling on de- material block,
Unclamp workpiece, then workpiece taken out, be once again secured in down tearing punch and under tear and tear on punch fixed block under between die；
S4, the hemisection of lower essence：After secondary fixation, reuse motor-driven and take off material dowel steel, tear punch under drive and push, utilize
Under tear punch and under tear between die chucking power effect, the lower surface of workpiece is carried out hemisection, and forms grinding roller R angle, complete
Make.
As a kind of preferred technical scheme of the present invention, described on tear die, under tear the inner surface of die and be both needed to be polished into R
Angular formula, it has to be noted that will at the uniform velocity push during pushing.
As a kind of preferred technical scheme of the present invention, described on tear punch fixed block and under tear the top of punch fixed block
It is both needed to be polished into obtuse angle form, avoid answering that pressure is excessive leads to workpiece to rupture in extrusion process energetically.
As a kind of preferred technical scheme of the present invention, should first go through whether complete hemisection before the demoulding, grinding roller R
Continue pressurization it is not possible to direct demold when angle is unsatisfactory for requiring.
Present invention also offers a kind of upper and lower hemisection mould of ornamental strip, including Shang Jing hemisection mechanism and Xia Jing hemisection mechanism,
Described Shang Jing hemisection mechanism wears at center and is connected to de- material dowel steel, and described de- material dowel steel runs through Shang Jing hemisection mechanism up to from lower essence
Pass in hemisection mechanism, the outer surface of de- material dowel steel is socketed with de- material block；Described Shang Jing hemisection mechanism include tearing die and
On tear punch, and on tear die and be arranged on the top tearing punch, described Xia Jing hemisection mechanism tear under including punch and under tear recessed
Mould, and under tear punch and be arranged on down the top tearing die.
As a kind of preferred technical scheme of the present invention, described on tear the top of punch and be provided with and tear punch fixed block,
The top tearing punch fixed block on described is connected to the bottom tearing die.
As a kind of preferred technical scheme of the present invention, described under tear the bottom of punch and be provided with down and tear punch fixed block,
And under tear the bottom of punch fixed block and be connected to down and tear on die.
As a kind of preferred technical scheme of the present invention, described on tear punch fixed block with above tear die, under to tear punch solid
Determine block and under tear all to leave certain gap between die and formed and bayonet socket be installed, for being fixed workpiece to be processed.
As a kind of preferred technical scheme of the present invention, described de- material block be closely embedded in respectively tear die with tear recessed
The inner surface of mould, with de- material dowel steel up and down motion will drive tear die with tear die and move up and down, carry out de- expecting
Or hemisection operation.
Beneficial effects of the present invention：
The present invention first by product up smart hemisection, makes the top edge of product produce grinding roller R angle；Again by product down smart hemisection, allow
Product also produces grinding roller R using the lower surface that the chucking power of material makes product during down, thus reaching the outer of product
See and require, solve product R angle and flatness needs the operation of secondary mould processing, convenient production process operation, cost is relatively low.
