Abstract
Mechanism of the present invention discloses a kind of waste material cutting mechanism of car panel die application.The mechanism is arranged on upper mould body, and deburring insert 4 realizes the purpose of mould waste knife under deburring and avoidance by being slided up and down in the mechanism.Mechanism of the present invention produces the problem of tear when overcoming deburring, reduce the possibility for producing deburring burr and chip, improves the surface quality of product.
Description
Technical field
The waste material cutting mechanism applied the present invention relates to the manufacturing technology field of Automotive Cold Pressing Dies tool, more particularly to during a kind of tool deburring of Automotive Cold Pressing Dies.
Background technology
At present, when especially outer covering piece mould carries out deburring to Automotive Cold Pressing Dies tool, in order to reduce die procedure number reduces cost, generally waste material is pared off operation is as much as possible, but in order to ensure that every sheet waste material can not exceed the size of regulation, traditional method is the size that waste material is controlled by increasing waste knife.Although this method can reach control waste material size purpose, due to upper die repair side cutter block cutting edge waste material cutter position in order under avoiding mould waste knife can not be consistent height（In the presence of the jump of general 5mm）, thus result in waste material local at waste knife and do not machine away, but what tear was fallen, a large amount of burrs and chip can be also produced while tear.
The content of the invention
It is an object of the invention to overcome the shortcomings of above-mentioned technology, and the waste material cutting mechanism applied during a kind of Automotive Cold Pressing Dies tool deburring is provided, the problem of tear is produced when can effectively overcome deburring, the possibility for producing deburring burr and chip is reduced, the surface quality of product is improved.
The present invention to achieve the above object, using following technical scheme：
A kind of waste material cutting mechanism applied during Automotive Cold Pressing Dies tool deburring, it is characterised in that：Including base 1, insert 2, insert 3, deburring insert 4, baffle plate 5, baffle plate 6, nitrogen spring 7, screw 8, screw 9, screw 10, the insert 2,3 is arranged on base 1, the baffle plate 5,6 is fixedly mounted in insert 2,3 with screw 8,9, the deburring insert 4 is arranged between insert 2,3 and baffle plate 5,6, and the nitrogen spring 7 is arranged on base 1 and withstands deburring insert 4.
Brief description of the drawings：Fig. 1 is waste material cutting mechanism shaft side figure.
Fig. 2 is waste material cutting mechanism sectional view.
Fig. 3 is the waste material cutting mechanism shaft side figure with lower mould waste knife and mold closed condition.
Fig. 4 is the waste material cutting structure schematic diagram of traditional mold closed condition with lower mould waste knife.
Specific embodiment：As shown in figure 1, described waste material cutting mechanism can be individually attached on upper mould.Described waste material cutting mechanism component includes base 1, insert 2, insert 3, deburring insert 4, baffle plate 5, baffle plate 6, nitrogen spring 7, screw 8, screw 9, screw 10.Described base 1 is arranged on upper mould body by screw, pin；Described insert 2,3 is arranged on base 1 by screw, pin；Described baffle plate 5,6 is arranged in insert 2,3 by screw；The nitrogen spring 7 is arranged on base 1 by screw；Deburring insert 4 is arranged between insert 2,3 and baffle plate 5,6 and keeps sliding relative movement, and the bottom surface of deburring insert 4 to withstand on nitrogen spring therewith, and the motion of deburring insert 4 is controlled by the pressure of nitrogen spring.Need especially emphasize be：1. size marking " L " and " H " in figure can produce the standards body of sizes specification according to the difference of actual conditions, it is had enough allowance.2. nitrogen spring 7 is used to ensure the deburring power of the initial pressure more than deburring insert 4 of nitrogen spring according to the nitrogen spring that the difference of the deburring power of deburring insert 4 can select different initial pressures.Operation principle of the invention is easily understood, when upper mould body is moved down with lathe, deburring insert 4 keeps the continuity of cutting edge to complete deburring work simultaneously in the presence of the initial pressure of nitrogen spring 7 with insert 2,3, continue to move down after having repaiied side, deburring insert 4 is contacted with lower mould waste knife, nitrogen spring starts compression, deburring insert 4 starts to keep geo-stationary with lower mould waste knife, insert 2,3 continues to move downward, waste material cutting is carried out with the effect of lower mould waste knife by insert 2, it is achieved thereby that the function of deburring and waste material cutting.
Beneficial effects of the present invention：
Mechanism of the present invention waste knife when deburring is solved the problems, such as is produced in tear, the continuity for ensureing that upper die repair side insert ensures trimming edge at waste knife is realized, unlike traditional deburring insert has jump at waste knife.Simple structure of the present invention, easy to manufacture.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; some improvements and modifications can also be made, these improvements and modifications also should be regarded as protection scope of the present invention.
