Abstract
The invention discloses a tramcar join and a producing method thereof. The producing method comprises the following steps: (1) polyurethane or polystyrene is made into liquid by physical or chemical method for spare use; (2) rubber or a leather belt is made into blank by cutting and the blank is fixed in a mould; (3) the liquid polyurethane or polystyrene is poured into the mould to be fused with the rubber or leather belt blank, so as to obtain fusion; (4) the fusion is put into a vulcanizing plant where the temperature is kept at 100-120 DEG C to be solidified and shaped, thus obtaining the tramcar join. The tramcar join produced by adopting the method of the invention has excellent collision resistance and high tear resistance, can effectively prevent tramcars from colliding and producing consequential sparkle from the collision, so as to prevent blast, and has low production cost and long service life more than three years.
Description
Technical field
The present invention relates to a kind of collision prevention device and preparation method thereof, relate in particular to a kind of mine car striking head and preparation method thereof, belong to the collision prevention device field.
Background technology
Mine car in order to prevent collision, need be met and discussed in the front end or the two ends setting of mine car in running.Existing meeting and discussing normally formed by polyurethane preparation, and anti-collision, tear resistance height can effectively stop mine car and mine car to collide and the spark of generation, prevent blast.
But adopt polyurethane or rubber to be prepared from, shorter by the service life of meeting and discussing that rubber is prepared from, be generally 6-12 month; Be significantly improved the service life of meeting and discussing that is formed by polyurethane preparation, and how about 3 years, but preparation cost is too high, haves much room for improvement.
Summary of the invention
Technical problem to be solved by this invention provides a kind of new mine car striking head, lower, the long service life of the preparation cost of this mine car striking head.
Technical problem to be solved by this invention is achieved through the following technical solutions: a kind of mine car striking head may further comprise the steps and is prepared from:
(1) make it become liquid state with physics or chemical method polyurethane or polystyrene, standby;
(2) (blank can not have given shape and specification rubber or belt to be cut into blank, can determine difformity and specification according to the shape of position of putting into or mould), be fixed among the mould (mould can according to the specification of mine car maybe needs adopt conventional material preparation, those skilled in the art can prepare the mould of all size or shape according to actual conditions);
(3) polyurethane of liquid state or polystyrene are poured in the mould with mould in rubber or belt blank merge mutually, obtain fusions;
(4) fusions is put into vulcanization plant, maintain the temperature between the 100-120 degree, treat fusions curing molding (approximately vulcanizing about 5-7 hour), promptly.
The inventor is by further experiment discovery, if adopt following any technological means among the above-mentioned preparation method, technique effect all can be significantly improved:
(1) in the step (1) rubber or belt cut into blank after, blank is dried; Water evaporates is fallen; If the water evaporates in the blank is not fallen, in the operation of back, can occur because of water vapor produces bubble, cause the polyurethane the inside hole of gasification to occur, influence performance;
(2) in the step (1) with the blank that cuts into and polyurethane or the contacted one side polishing of polystyrene zigzag, help polyurethane to combine with offset plate closely like this;
(3) in the fusions described in the step (3), count by volume, the volume of rubber or belt accounts for 3/4ths of fusions cumulative volume, polyurethane or polystyrene volume account for fusions 1/4th (this part puts into iron-clad to account for 3/4ths rubber of fusions cumulative volume or belt, in the process of using, can effectively do not used.And other 1/4th polyurethane or polystyrene partly are only effective working face, can effectively save cost like this, and not influence the prepared serviceability of meeting and discussing);
(4) in the step (4) fusions is put into vulcanizing chamber, the temperature that keeps vulcanizing chamber is increased to vulcanizing chamber pressure between the 32-50 ton about half an hour between the 100-120 degree; In addition, in this process, can after fusions has certain degree of hardness, mould be removed as merge use (improving the utilization rate of mould) next time, vulcanize with the hardness of fusions merely, finish up to sulfuration.
The used above-mentioned various raw materials of the present invention all can be bought from the chemical industry shop and obtain, and its specification meets industry standard.
Adopt the prepared mine car striking head of the inventive method to have good crash worthiness energy, tear resistance height, can effectively stop mine car and mine car to collide and the spark of generation, prevent blast; Preparation cost is low, and surpass more than 3 years service life more.
The specific embodiment
Further describe the present invention below in conjunction with specific embodiment; what those skilled in the art should understand that is; down can make amendment or replace without departing from the spirit and scope of the present invention, but these modifications and replacing all fall within the scope of protection of the present invention the details of technical solution of the present invention and form.
