Abstract
The invention discloses a method for fabricating a stretcher cross bar. The method comprises the steps of conducting waxing on a carbon fiber reinforcement tube core mold; producing carbon fiber reinforcement tubes in a rolled mode; producing a layer structure in a rolled mode; winding strips; conducting baking; after the baking is completed, conducting the demolding; cutting away polypropylene film strips on the surfaces of the carbon fiber reinforcement tubes; conducting cutting and grinding till the required dimension is reached; cleaning the surface of the core mold in the first place, and brushing a release agent on the surface of the core mold, wherein the cross bar main bar forming core mold is divided into a left mold half and a right mold half; sleeving the left mold half and the right mold half with the carbon fiber reinforcement tubes which are formed ready in advance; winding cloth in which layers are designed ready in advance onto the core mold; producing a pressurized plastic strip in a rolled mode, and sending the whole assembly into a drying oven for curing molding; removing the core mold; removing the pressurized plastic strip. According to the method for fabricating the stretcher cross bar, the formation process is simple, the formed stretcher cross bar is little in deformation in the using and load-bearing process, no shaking occurs in the process when a sick or injured person is conveyed, the weight is low, the cross bar is convenient to carry, the assembling is simple, and the occupied space when the stretcher cross bar is stored is small.
Description
Technical field:
The present invention relates to a kind of pole process technology, is specifically a kind of manufacture method of stretcher cross bar.
Background technology:
Stretcher cross bar now only has two kinds, and one is single pole through type, and one is external reinforcement rod-type.Single pole through type cross bar: physical property intensity is weak, in use and loading process, force part easily produces slight crack and fracture; Use and in loading process crossbar deformity amount large, easily swing up and down, make the noneffectives that overlies in transport process because stretcher cross bar swings up and down too large and touch wound and deepened the pain of noneffectives; In order to promote cross bar intensity, reduce deflection, single pole through type cross bar only has increase wall thickness.The burden of carrying personnel can be increased like this, reduce handling efficiency, affect noneffectives's golden hour.External reinforcement rod-type cross bar: Heavy Weight, adds the heavy burden of carrying personnel, reduce transporting velocity, affects noneffectives's golden hour; Profile and assembling are too complicated; Take up space large.
Summary of the invention:
Technical problem to be solved by this invention is, a kind of manufacture method of stretcher cross bar is provided, the method make stretcher cross bar use and loading process in deflection little, transport noneffectives process in can not rock, more stable, lightweight, be easy to carry, alleviate the burden of carrying personnel, profile is succinct, assembling is simple, takes up space little when stretcher cross bar is deposited.
Technical solution of the present invention is, provide a kind of manufacture method of stretcher cross bar, it comprises the following steps,
The first step, carbon fiber reinforced pipe core is waxed;
Second step, rolls carbon fiber reinforced pipe: roll on carbon fiber reinforced pipe core by the carbon fibre initial rinse fabric designing laying according to row's stack structure order;
3rd step, Horizontal belt winder tape wrap on rolled carbon fiber reinforced pipe, the lined duct tail end flatiron having twined band scalds polypropylene film band;
4th step, is linked in the baking box of regulation, opens the oven cooking cycle setting parameter;
5th step, has toasted the rear upper ingot stripper demoulding;
6th step, the polypropylene film band on carbon fiber reinforced pipe surface of pruning;
7th step, the size cutting on demand of upper cutting machine, is ground to the size of needs centreless grinding machine on the carbon fiber reinforced pipe of well cutting length;
8th step, cross bar mobile jib molding core divides left and right half module, first by clean for mandrel surface clean, brushes releasing agent;
9th step, is inserted in the carbon fiber reinforced pipe of forming in advance on the half module of left and right, and mechanical caging carbon fiber reinforced pipe cylindrical flushes with main mandrel cylindrical;
Tenth step, is rolled onto on core by the cloth of pre-designed laying;
11 step, rolls and adds compression moulding band, enters curing oven molding;
12 step, pulls out core;
13 step, removes and adds compression moulding band.
As preferably, the waxing temperature in the first step controls at 80-85 DEG C.Wax effective.
Further, to prune with cutter in the 6th step the polypropylene film band on carbon fiber reinforced pipe surface.
The present invention has the following advantages compared to prior art: moulding process of the present invention is simple, and process controllability is good, can duplication of production, be applicable to producing in enormous quantities, reduce production cost, and, the stretcher cross bar of molding use and in loading process deflection little, can not rock in the process of transporting noneffectives, more stable, lightweight, be easy to carry, alleviate the burden of carrying personnel, profile is succinct, assembling is simple, takes up space little when stretcher cross bar is deposited.
Detailed description of the invention:
Below in conjunction with detailed description of the invention, the invention will be further described:
Embodiment
A manufacture method for stretcher cross bar, it comprises the following steps,
The first step, carbon fiber reinforced pipe core is waxed, and waxing temperature controls at 80-85 DEG C;
Second step, rolls carbon fiber reinforced pipe: roll on carbon fiber reinforced pipe core by the carbon fibre initial rinse fabric designing laying according to row's stack structure order;
3rd step, Horizontal belt winder tape wrap on rolled carbon fiber reinforced pipe, the lined duct tail end flatiron having twined band scalds polypropylene film band, and during to prevent from toasting, tail end scatters;
4th step, is linked in the baking box of regulation, opens the oven cooking cycle setting parameter;
5th step, has toasted the rear upper ingot stripper demoulding;
6th step, the polypropylene film band on carbon fiber reinforced pipe surface of pruning with cutter;
7th step, the size cutting on demand of upper cutting machine, is ground to the size of needs centreless grinding machine on the carbon fiber reinforced pipe of well cutting length;
8th step, cross bar mobile jib molding core divides left and right half module, first by clean for mandrel surface clean, brushes releasing agent;
9th step, is inserted in the carbon fiber reinforced pipe of forming in advance on the half module of left and right, and mechanical caging carbon fiber reinforced pipe cylindrical flushes with main mandrel cylindrical;
Tenth step, is rolled onto on core by the cloth of pre-designed laying;
11 step, rolls and adds compression moulding band, enters curing oven molding;
12 step, pulls out core;
13 step, removes and adds compression moulding band.
The built-in bracing or strutting arrangement of the stretcher cross bar made is carbon fiber reinforced pipe, and built-in bracing or strutting arrangement overall dimensions and Lay up design are required to determine by cross bar intensity and toughness, weight and supervisor's internal diameter.For the feature of built-in bracing or strutting arrangement cross bar and the requirement in conjunction with every technical parameter, stretcher cross bar adopts the mode of post forming to carry out operations for forming.
Below only just preferred embodiment of the present invention is described, but can not be interpreted as it is limitations on claims.
