The cutting method of special hose
Technical field
The present invention relates to a kind of cutting method of special hose, particularly relate to a kind of special hose method that cut simultaneously at two ends after locating.
Background technology
There are defectives such as sebific duct end head length degree instability, material loss is big, working condition is poor, work efficiency is low in automobile with the method for the special-shaped rubber hose employing rotary blade of monolithic (electronic) termination secondary cut at present.Prior art mainly shows as:
1, the cutting mode that adopts at present is the method that adopts the rotary blade of monolithic (electronic) termination secondary cut, when rotating cutting at a high speed, blade easily produces a large amount of frictional heats, the a large amount of heats that produced not only easily cause loss to cutting blade, and the rubber material is also had certain destructiveness.For reducing the heat that friction is produced, for this reason, must be to the cutting blade surface sprinkling.This has not only increased energy consumption, and production site is dropped down has everywhere expired water, and production environment is impacted, and simultaneously producers cause harmful effect because of being in wet environment for a long time to healthy.
2, the cutting mode that adopts at present must be made open ended mould by the spatial form of special hose woolen cloth and be divided into two, and will have the mould merging of sebific duct two ends shape to be cast on the electric sucker.Before each the production, must proofread and correct and sebific duct is carried out trial cut cut, meet the requirement of check mould, can produce until institute's cutting products to die location.Because of verification has produced a large amount of expenditures of time.Simultaneously, by the slip that is cast in the mould on the electric sucker being cut the sebific duct woolen cloth easily in the loyal phenomenon that walks of sliding process, sebific duct end head length degree can not get effective assurance.
3, the cutting mode that adopts at present, each cutting can only be cut an end of sebific duct woolen cloth, and cut needs behind the end overturn to sebific duct can cut the other end, and finishing woollen cutting of a sebific duct need secondary cut.
Summary of the invention
The cutting method that the purpose of this invention is to provide a kind of special hose just provides a kind of special hose method that cut simultaneously at two ends after locating.The invention solves special hose termination length problem of unstable, remedied the big deficiency of prior art material loss.
The cutting method of a kind of special hose of the present invention cuts into the special hose product with cutter simultaneously with two ends, back, the woollen location of special hose, and the positioning accuracy of the cutter at two ends has just been determined cutting accuracy.
As optimized technical scheme:
The cutting method of aforesaid a kind of special hose, wherein, described special hose woolen cloth comprises n special hose product and cutting surplus, described cutting surplus comprises feed cutting surplus and the woollen two ends of special hose allowance, the special hose woolen cloth can use n+1 that cutter is cut simultaneously and obtain n special hose product through one-time positioning.
The cutting method of aforesaid a kind of special hose, wherein, described location is to make open ended mould by the spatial form of special hose woolen cloth, and utilizes pressure that the special hose woolen cloth is fixed in the mould, and described pressure can be to have adopted modes such as pressing plate, briquetting.
The cutting method of aforesaid a kind of special hose, wherein, described mould is when being used for the woollen location of special hose of two above special hose products compositions, and mould leaves tool slot between the special hose product.
The cutting method of aforesaid a kind of special hose, wherein, described cutter is blade or cutterhead.Selecting cutting with blade or use cutterhead according to the material situation of special hose, for soft material, generally use blade extruding cutting, also can be Dragsaw type cutting, and blade can the band saw tooth; For the material of hard special hose, then adopt cutterhead rotation cutting.
The cutting method of a kind of special hose of the present invention, the problem that cutting exists according to traditional approach, designed a kind of with the first method that afterwards adopts air pressure (hydraulic pressure) kind of drive multi-cutter one-step perpendicular cuts of locating of special hose, can realize single or many special hose terminations are once cut, improve the dimensional accuracy and the dimensional stability of sebific duct end head length degree.Owing to can realize the once cutting simultaneously of many sebific ducts, can reduce material loss more than 30%, improve work efficiency more than 80%.The cutting method of a kind of special hose of the present invention is applicable to the cutting of the special hose of various spatial forms.
The invention has the beneficial effects as follows:
The cutting method of a kind of special hose of the present invention is that single or many special hose terminations are once cut, and improves the dimensional accuracy and the dimensional stability of sebific duct end head length degree; Owing to can realize the once cutting simultaneously of many sebific ducts, can reduce material loss more than 30%, improve work efficiency more than 80%.
The specific embodiment
Below in conjunction with the specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
The cutting method of a kind of special hose of the present invention cuts into the special hose product with cutter simultaneously with two ends, back, the woollen location of special hose, and the positioning accuracy of the cutter at two ends has just been determined cutting accuracy.
Wherein, described special hose woolen cloth comprises n special hose product and cutting surplus, described cutting surplus comprises feed cutting surplus and the woollen two ends of special hose allowance, and the special hose woolen cloth can use n+1 that cutter is cut simultaneously and obtain n special hose product through one-time positioning.
Described location is to make open ended mould by the spatial form of special hose woolen cloth, and utilizes pressure that the special hose woolen cloth is fixed in the mould, and described pressure can be to have adopted modes such as pressing plate, briquetting; Described mould is when being used for the woollen location of special hose of two above special hose products compositions, and mould leaves tool slot between the special hose product.Described cutter is blade or cutterhead.
The cutting method of a kind of special hose of the present invention, the problem that cutting exists according to traditional approach, designed a kind of with the first method that afterwards adopts air pressure (hydraulic pressure) kind of drive multi-cutter one-step perpendicular cuts of locating of special hose, can realize single or many special hose terminations are once cut, improve the dimensional accuracy and the dimensional stability of sebific duct end head length degree.Owing to can realize the once cutting simultaneously of many sebific ducts, can reduce material loss more than 30%, improve work efficiency more than 80%.The cutting method of a kind of special hose of the present invention is applicable to the cutting of the special hose of various spatial forms.
