Abstract
The invention discloses a machining method of a track clamping plate. The machining method comprises the steps of heating, rolling, blanking and punching. Compared with a conventional machining method, the method adopts a hot rolling mill for rolling billet, thus not only greatly improving the production efficiency of products, but also ensuring that the thickness of obtained parison is consistent and the quality of the produced track clamping plate is reliable so as to better meet the requirements of customers; of course, the parison of the track clamping plate can be also obtained by cold rolling flat steel directly, but the cost and energy consumption of rolling equipment are increased accordingly as the rolling pressure required for cold rolling is higher compared with hot rolling, and simultaneously the mechanical property of the track clamping plate is poorer as the cold rolling does not comprise thermal plastic compression. Thus, the parison obtained by hot rolling the flat steel is not only high in efficiency and low in cost, but also reliable in quality so as to better meet the requirements of production.
Description
Technical field
The invention belongs to the track technical field, specifically is a kind of processing method of rail clamp, more specifically is a kind of processing method that is used for the rail clamp of track connection.
Background technology
Rail clamp is mainly used in track and connects, and compares traditional welding, adopts rail clamp to connect time and labour saving more, and can change at any time, therefore is used widely.
The procedure of processing of conventional rails clamping plate is following: at first be that band steel is heated to 800 ℃～900 ℃; And then under air hammer, forge repeatedly, obtain the parison of rail clamp; Cut according to the length of rail clamp through blanking machine and then; Punching under punch press again after cutting is accomplished obtains the finished product rail clamp.The weak point of above-mentioned technology is: forge the parison that obtains rail clamp repeatedly through air hammer; Not only influenced the production efficiency of rail clamp; And the rail clamp thickness produced of the method that adopts air hammer to forge this hand-guided repeatedly etc. is inequality; The quality of product can't guarantee, can not satisfy client's demand preferably.
Summary of the invention
The object of the present invention is to provide the processing method of a kind of production efficiency height, reliable quality rail clamp, satisfy client's demand better.
Technical scheme of the present invention is following: a kind of processing method of rail clamp, and step is following:
Heating: with blank heating to 700 ℃～800 ℃;
Rolling: heating is rolled blank after accomplishing through hot-rolling mill;
Blanking: blank is cut through blanking machine;
Punching: blank is carried out punching, obtain the finished product rail clamp.
Preferably, said step S1 adopts and pushes away the steel stove and heat.
Preferably, the blank of said step S2 is a band steel.
Preferably, the punch press cold punching of 80T～120T is adopted in the punching of said step S4.
Compare traditional diamond-making technique, the present invention is rolled blank through hot-rolling mill, has not only significantly improved production efficiency of products, and the parison thickness that obtains is consistent, and the rail clamp reliable in quality of producing has satisfied client's demand better; Certainly, parison also can directly obtain through band steel is cold rolling, but because cold rolling to compare the draught pressure that hot rolling needs bigger; The cost and the energy consumption of rolling equipment have correspondingly been increased; Simultaneously cold rolling the mechanical property of rail clamp is relatively poor not through hot plasticity compression, so band steel obtains parison through hot rolling, and not only efficient is high, cost is low; And reliable in quality, more can satisfy the production needs.
Description of drawings
Fig. 1 is a process chart of the present invention;
Fig. 2 is structural change figure of the present invention.
The specific embodiment
For making the object of the invention, technical scheme and advantage clearer, the present invention is further described below in conjunction with accompanying drawing and specific embodiment.
Referring to Fig. 1 and Fig. 2, the procedure of processing of rail clamp is following:
Heating: band steel put into push away the steel stove and be heated to 800 ℃;
Rolling: as after heating is accomplished band steel to be released from push away the steel stove under the roll of hot-rolling mill and be rolled, obtain the parison of rail clamp;
Blanking: parison is cut according to the length of finished product rail clamp through blanking machine;
Punching: after cutting is accomplished the punch press of parison through 100T carried out cold stamping, obtain the connecting hole of rail clamp, punching press obtains the finished product rail clamp after accomplishing.
Certainly; The present invention also can have other various embodiments; Under the situation that does not deviate from spirit of the present invention and essence thereof; Those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
