Description
Technical field
The overlap that the present invention relates to a kind of rubber is to cutting tool.
Background technology
Overlap is to overflow into gap locations such as mould spue line or stripper pin in the moulding process and stay the residue material limit on the Injection moulded part.
Also there is overlap in the rubber edge in the production process of rubber, and also because the contact-making surface driving fit precision between punch and the die is low, and the material amount is too much, clout leaks at the weak seal place and forms overlap.Rubber overlap processing method is varied in the prior art, mainly comprises following three kinds: free-hand facture, freezing processing method, cylinder grinding method.Requirement to hardware when these three kinds of methods are used has nothing in common with each other, and it is also inequality to handle resulting effect, and processing cost has notable difference.
(1) free-hand facture: the workman is free-hand to be separated rubber along tearing mouthful (the thinner thickness place between overlap and the rubber) certainly open with inside and outside overlap, and will fail to handle clean remaining overlap by simple cutting implement such as flat-nose pliers etc. and wipe out.This method is simple and practical, does not need the main equipment input, but this method processing quality is undesirable; Secondly, the technical merit to the workman has certain requirement.If flat-nose pliers such as improper use, can break rubber or cut off the part of rubber body, and then cause substandard products.Utilize the method,, need to accomplish,, good mould just must be arranged so will guarantee reasonably to tear degree of lip-rounding shape open certainly through injection moulding because form from tearing mouth open to having relatively high expectations of mould.Receive the mould burn-in effects in case tear a mouthful shaping certainly open, the mouth of tearing open certainly of injection moulding gained makes the overlap processing unclean when overlap separates easily, tears a mouthful residual overlap open.
(2) freezing processing method: effective ways are arranged as batch process rubber burrs a kind of; The freezing processing method is widely used; It utilizes liquid nitrogen that rubber is cooled to subzero tens degree rapidly, reaches the purpose of low temperature brittleness, makes rubber and inside and outside overlap be in a kind of embrittlement state; Utilize compressed air that a kind of tiny plastic cement material for making clothes blown out at a high speed again, make it to act on the rubber and inside and outside overlap of low temperature brittleness.From tearing a mouthful thinner thickness open, therefore after receiving plastic cement material for making clothes high-speed impact, break easily, and then play the purpose of removing overlap.This method is applicable to the overlap work of treatment of rubber in enormous quantities, and production efficiency is higher.But, utilize this side need drop into hardware setting preferably, as refrigerator and with supporting recycling device that can reclaim liquid nitrogen in a large number of refrigerator or special supply station, so processing cost is higher.The purpose of low temperature brittleness is to make from tearing the state that mouthful rubber that goes out is in embrittlement open; But whole rubber all is in the low temperature brittleness state during practical operation; The plastic cement material for making clothes that blows out so at a high speed also can strike on the body at bump when tearing mouth open; And then it is damaged to cause body to produce, and influences the quality of final products.The whole low temperature brittleness of rubber can cause harmful effect to properties of product, especially the situation of multiple low-temperature embrittlement deflashing.Utilize this method also must guarantee to be in the specific requirement from the thickness of tearing mouth open, if thickness is excessive, then very easily cause the residual phenomenon of overlap, treatment effect is not good.
(3) cylinder grinding method: rubber is put into cylinder with the steel ball that some differ in size.In the process that drum turning rolls, the inside and outside overlap of dawdling when relying on steel ball to contact with rubber is to reach the purpose of handling overlap.This method equipment needed thereby drops into low, economical and practical, but the effect of handling is undesirable, and is also higher to the requirement of tearing open certainly mouthful, tears mouthful thickness certainly open when undesirable, and the overlap treatment effect is just poor.The rigidity of invar pearl is far above the rigidity of rubber, and the outward appearance to rubber produces damage greatly behind the steel ball bump rubber in rolling process, influences the presentation quality of rubber.
In sum, handle overlap through prior art and very easily cause the phenomenon that overlap is residual, damage body, the overlap treatment effect is not good.
Summary of the invention
The overlap of rubber that the technical problem that the present invention will solve provides that a kind of processing cost is low, non-trimming is residual, do not damage body is to cutting tool.
Ask to solve the problems of the technologies described above that the present invention adopts following technical scheme: the overlap of this rubber comprises upper substrate and infrabasal plate at least to cutting tool, and said upper substrate is provided with the last cutter head that is used to excise overlap; The said cutter head of going up is provided with the parallel blade of twice, and said infrabasal plate is provided with following cutter head and the support board that is used to excise overlap, and said cutter head down is provided with the parallel blade of twice; Said support board is provided with and holds the through hole of cutter head down; Said down cutter head be positioned at through hole and down the blade on the cutter head maintain an equal level with the support board surface, said go up cutter head be positioned at cutter head down directly over, the blade of said upward cutter head and the blade of following cutter head are in opposite directions and right; Also be provided with the flake plate on the said upper substrate; Said flake plate is provided with the T shape through hole that is used to hold cutter head, and said upward cutter head is T-shaped, and said blade is arranged on diameter minimum this end and this end and passes T shape through hole; The surface of said blade and flake plate maintains an equal level, and said going up between cutter head and the upper substrate is provided with support spring.
The pendulum position of last cutter head and following cutter head is consistent with the overlap present position on the rubber, through utilizing the most effectively contraposition cutting method, can directly overlap be separated with body, has avoided the residual situation with the damage body of overlap.The contraposition cutting method is only effectively cut to overlap, and operating efficiency is high like this; And can be used for automatic lot production, for the automatic updating of rubber production line provides condition.
Can play the purpose of separating overlap through the flake plate.The overlap that can make disengaging after the overlap in excision like this is away from body, and then is convenient to the rubber of taking.This flake plate also plays the function of pre-compacted, because the blade of flake plate surface and last cutter head maintains an equal level, just can be pressed on from tearing a mouthful place open so compress the rubber rear knife edge at the flake plate, can prevent that like this rubber from producing displacement.
As of the present invention preferred, said support board is movably connected on the infrabasal plate through elasticity reset device.When rubber was pressed down by last cutter head, rubber moved downward with support board, till tearing the blade of mouthful bottom with following cutter head certainly open and contacting.Like this rubber tear certainly mouthful up and down that two places are all compressed by blade open, thereby come correct polarizing slot position through support board, prevent that cutter head from pressing down back rubber deformation and the phenomenon that causes incision site to squint.
As of the present invention preferred; Said upper substrate such as is provided with at high bolt; One end of high bolt such as said is fixedly connected with last cutter head, and the other end and upper substrate flexibly connect, and said support spring is enclosed within etc. on the high bolt; One end of high bolt such as said and upper substrate flexibly connect, the other end and the flexible connection of last cutter head.This structure forms the guiding mechanism of cutter head, and is in the same vertical plane in the time of guaranteeing to go up cutter head work, has important function to keeping the incision site uniformity.
The present invention adopts technique scheme: through implementing the contraposition cutting method, the overlap of this rubber can be handled overlap fast and effectively to cutting tool, and have simple to operate, processing cost is low, excision back noresidue, undamaged advantage.Utilize this overlap to cutting tool gained rubber good looking appearance, do not need secondary operations, this is significant to reducing the enterprise-quality management cost.
