Description
Technical Field
The invention relates to the technical field of wrenches, in particular to a preparation method of a carbon fiber-based explosion-proof double-ended solid wrench.
Background

The explosion-proof double-end solid wrench is a product in an explosion-proof tool, is a most frequently used manual tool in the explosion-proof tool, and the most common method for preparing the explosion-proof double-end solid wrench at present comprises the steps of gravity casting, machining, quenching treatment, surface spraying treatment and the like, and has the defects of multiple preparation procedures and long preparation period.
Disclosure of Invention
In order to facilitate understanding of the technical aspects and technical effects of the present invention, the present invention will be described in detail with reference to the following specific embodiments. Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. In case of conflict, the present specification, definitions, will control.
The invention provides a preparation method of a carbon fiber-based explosion-proof double-ended solid wrench, which comprises the following steps:
(1) Extruding, granulating and drying poly (arylene ether ketone), polytetrafluoroethylene, and solid materials containing carbon fibers, solid metal compounds and metal powder to obtain carbon fiber explosion-proof tool granules;
(2) Preheating the die, putting the double-end solid wrench metal insert into the die, heating the injection molding machine to fully melt the carbon fiber explosion-proof tool granules obtained in the step (1), and injecting, maintaining pressure, cooling and cutting off a water gap.
In the invention, the combination of the carbon fiber explosion-proof tool granules and the double-end solid wrench metal insert has the advantages of light weight and stronger strength compared with a single double-end solid wrench made of metal, and compared with the existing double-end solid wrench made of metal, the production period can be reduced by about 3/4, and meanwhile, the special carbon fiber explosion-proof tool granules enable the finally prepared carbon fiber-based explosion-proof double-end solid wrench to have excellent explosion resistance.
As a preferred embodiment of the present invention, the poly (arylene ether ketone) is at least one selected from the group consisting of polyether ether ketone, polyether ketone and polyether ether ketone, and preferably polyether ether ketone.
The polyether-ether-ketone is an organic thermoplastic polymer with excellent mechanical strength and impact toughness, and the polyether-ether-ketone is used in the invention to ensure that the finally prepared carbon fiber-based explosion-proof double-ended solid wrench has excellent impact toughness, and the source of the polyether-ether-ketone is not particularly limited, and can be obtained by the market, for example, the brand of the polyether-ether-ketone is Jilin grinding high-plasticity 330G.
As a preferred embodiment of the present invention, the mass of the polytetrafluoroethylene is 1 to 10wt%, preferably 2 to 8wt%, and more preferably 1 to 3wt% of the mass of the poly (arylene ether ketone).
In the present invention, in order to increase the corrosion resistance of the final carbon fiber-based explosion-proof double-ended solid wrench, a specific amount of polytetrafluoroethylene is added into the system, and the applicant has unexpectedly found that the addition of polytetrafluoroethylene can increase the comprehensive properties of the product while allowing the surface of the product to have a smooth appearance, probably because of a certain vinyl structural unit of polytetrafluoroethylene, which acts on the solid material, so that the dispersibility of the solid material in the system is increased, while also having a certain lubricating effect, so that the surface of the product is smooth.
As a preferable technical scheme of the invention, the polytetrafluoroethylene is PTFE Shandong China Shenzhou DF-203.
In order to increase the explosion resistance of the carbon fiber-based explosion-proof double-ended solid wrench, a solid material containing carbon fibers, a solid metal compound and metal powder is added into the system, and the mass of the solid material is 30-60wt%, preferably 35-45wt%, of the mass of the poly (arylene ether ketone) as a preferable technical scheme of the invention.
As a preferable technical scheme of the invention, the carbon fibers are chopped carbon fibers, preferably the length of the chopped carbon fibers is 2-5mm, and the fiber diameter is 6-20um.
In the invention, the chopped carbon fibers can be obtained by the market, for example, 6mm chopped carbon fibers with the model number of 1 mm-5 mm and the specification of Yaobang friction material factory are chopped.
In the present invention, the solid metal compound means a compound containing a metal element, and as a preferable embodiment of the present invention, the solid metal compound is at least one selected from the group consisting of magnesium diboride, magnesium oxide, aluminum oxide and hafnium boride, preferably magnesium diboride.
As a preferable technical scheme of the invention, the average grain diameter of the magnesium diboride is 600-1000 meshes.
As a preferred embodiment of the present invention, the metal powder is at least one selected from copper, nickel, indium, lead, bismuth, silver and palladium, preferably nickel.
As a preferred embodiment of the present invention, the nickel has an average particle diameter of 60 to 300 mesh, preferably 100 to 200 mesh.
While polytetrafluoroethylene-containing articles have very low friction coefficient and insufficient wear resistance in mating movement, the carbon fiber-based anti-explosion double-ended wrench of the present invention has particular wear resistance in long-term use, and the inventors hypothesize that the magnesium diboride is an ionic compound due to the synergistic interaction of the solid metal compound and the metal powder, and the magnesium and boron layers are alternately arranged to form an intercalation compound, so that when the articles are subjected to external friction force, the relative slippage possibly generated by the structure reduces the friction force, and also the magnesium diboride and nickel are chemically bonded in the injection process, so that the magnesium diboride is tightly combined with other components in the polyarylene ether ketone, and the articles show more excellent wear resistance; meanwhile, the metal powder has excellent heat conductivity, so that the softening rate of the carbon fiber explosion-proof tool granules can be improved, and the double-end solid wrench metal insert can be pressed into the carbon fiber material rapidly.
As a preferable technical scheme of the invention, the mass ratio of the carbon fiber, the solid metal compound and the metal powder is 1: (0.08-0.1): (0.08-0.1), preferably 1:1:1.
As a preferable technical scheme of the invention, carbon fiber, solid metal compound and metal powder are mixed and then ball-milled to obtain solid material; preferred conditions for the foregoing mixing include: the rotating speed is 60-80r/min, and the mixing is carried out for 20-30min; preferred conditions for the foregoing ball milling include: the ball milling rotating speed is 150-200r/min, the ball milling time is 2-4h, the ball milling ball is a stainless steel ball, and the ball diameter is 4-6mm.
In the invention, the inventor finds through a great deal of research and development experiments that the explosion resistance and impact toughness of the carbon fiber-based explosion-proof double-ended solid wrench can be improved by the ball milling implementation mode, and probably because the interface interlocking effect among carbon fibers, solid metal compounds and metal powder is enhanced by the ball milling mode, the binding force among all components is improved, and finally the impact toughness of a product is improved.
In the invention, it can be understood that the double-end solid wrench metal insert refers to a semi-finished product of a metal raw material which is cast and machined, and is not subjected to conventional heat treatment and/or spray coating treatment in the field.
As a preferable technical scheme of the invention, the double-ended solid wrench metal insert is a double-ended solid wrench copper alloy insert.
As a preferable embodiment of the present invention, in the step (1), conditions for extrusion granulation include: the temperature is 250-270 ℃, 280-300 ℃, 320-340 ℃, 340-370 ℃, 350-380 ℃ and the temperature of the machine head and the die is 350-380 ℃; setting the rotating speed: 80-100rpm, and the material retention period is 2-4min.
As a preferred technical scheme of the present invention, in the step (1), the drying conditions are as follows: drying in a circulating hot air dryer at 80-90deg.C for 1-2 hr.
