Abstract
A technology for finishing and reinforcing part includes designing and making a set of finishing mould composed of sizing die, finishing pin and finishing sleeve, loading the geometric body to be squeezed in the part into sizing die, squeezing it to pass it through the die, and squeezing again with another mould having different size. Its advantages are high effect on increasing size precision and reinforcing surface, and high productivity.
Description
(1) technical field
The present invention relates to the part finishing and strengthen technological method for processing, belong to the extrusion technique field in the machine-building.
(2) background technology
In machine industry, the mechanical presses technology can make that piece surface is strengthened, roughness is good, usually be applied to single geometrical body, the finish-milling method is generally adopted in processing to a plurality of geometrical bodies of a part, promptly mill out a geometrical body earlier with profile milling cutter, and then mill out other geometrical body successively, this processing method is simple, the production efficiency height, but machining accuracy is low.Exist the low problem of machining accuracy to adopt finish-milling-correct grinding method again in order to overcome the finish-milling method, when finish-milling, reserve certain surplus, finish grind successively then and be machined to design size, this processing method has improved machining accuracy, but needs frequent trimming wheel to guarantee to match with the geometry of profile milling cutter, makes at the bottom of the production efficiency, be not suitable for production in enormous quantities, particularly when the blind groove of processing open type, squeeze broken emery wheel easily, cause danger.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of machining accuracy height, steady quality is reliable, production efficiency is high part finishing reinforcing process method are provided.
The solution that the present invention adopts is:
Part finishing reinforcing process method may further comprise the steps:
(1). manufacture and design a cover finishing mold, finishing mold is made up of die finish, finishing pin and finishing cover, the finishing pin is contained in the die finish, the finishing cover is used for fixedly finishing pin, a finishing mold can be installed many finishing pins simultaneously, to guarantee a plurality of geometrical bodies extrusion process simultaneously to same workpiece, the shape chamber of die finish is a plurality of die finish of one group of different size according to the workpiece size tolerance design, and the finishing pin also is designed to a plurality of shanks of one group of different size tolerance;
(2). will leave geometrical body to be extruded in the workpiece of the certain allowance finishing pin position in the die finish of packing into;
(3). the part geometry body is pressed through finishing mold by extrusion equipment;
(4). part is extruded finishing mold by extrusion equipment;
(5). use the die finish and the finishing pin extruding finishing part geometry body of different size instead, to guarantee the secondary quality of fit that obtains broad in the tolerance range scope of broad of assembling.
Used extrusion equipment can be designed to special equipment, form by base, hydraulic pressure moving platform, bent plate, support, tip mechanism and holder, bent plate and hydraulic pressure moving platform are installed on the base, holder is installed on the hydraulic pressure moving platform, two tip mechanisms that are pressed into and extrude part are housed on it, support is installed on the bent plate, is provided with two stations that are used for support part.
The present invention adopts finishing mold that a plurality of geometrical bodies of workpiece are shaped by being pressed into, extruding secondary extrusion, is strengthened in the surface, and roughness is good, revised the morpheme error of geometrical body before the extruding, improved the dimensional accuracy and the accuracy of form and position between geometrical body, the production efficiency height, safe and reliable.
(4) description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view;
Fig. 3 is the structural representation of finishing mold of the present invention.
Wherein: 1, bent plate, 2, finishing mold, 3, part, 4, support, 5, tip mechanism, 6, holder, 7, hydraulic pressure moving platform, 8, base, 9, be pressed into station, 10, extrude station, 11, die finish, 12, the finishing pin, 13, the finishing cover
(5) specific embodiment
Accompanying drawing has provided structural representation of the present invention, presses the structural design of Fig. 1 and Fig. 2 and makes a special-purpose finishing hydraulic press.Hydraulic press is made up of base 8, hydraulic pressure moving platform 7, tip mechanism 5, support 4, holder 6 and bent plate 1, bent plate 1 and hydraulic pressure moving platform 7 are installed on the base 8, holder 6 is installed on the hydraulic pressure moving platform 7, two tip mechanisms 5 that are pressed into and extrude part are housed on it, support 4 is installed on the bent plate 1, is provided with two stations that are used for support part.Press the structural design of Fig. 3 and make a cover finishing mold 2, be made up of die finish 11, finishing pin 12 and finishing cover 13, finishing cover 13 is used for fixing finishing pin 12.The shape chamber of die finish is a plurality of die finish of one group of different size according to the workpiece size tolerance design, and the finishing pin also is designed to a plurality of shanks of one group of different size tolerance.During operation, with pack into the position of finishing pins 12 in the die finish 11 of part 3 geometrical bodies to be extruded that leave certain allowance behind the finish-milling, be put into hydraulic press and be pressed into station 9, start hydraulic press, hydraulic pressure moving platform 7 is pressed into die finish 11 by tip mechanism 5 with part 3, makes each geometrical body of finishing pin 12 extrusion sections 3; After being pressed into place, hydraulic pressure moving platform 7 is return and is resetted, and takes off die finish 11 and part 3, is put into to extrude station 10, starts hydraulic press, and workpiece is extruded die finish, and hydraulic pressure moving platform is return and resetted, and takes off workpiece, finishes the one action circulation.Use the die finish and the finishing pin extruding finishing part geometry body of different size instead, to guarantee the secondary quality of fit that obtains broad in the tolerance range scope of broad of assembling.
