Abstract
A kind of new technology of producing swords for fencing the present invention relates to the metal forming field.
The present invention adopts variable orifice pattern tool, makes the metal stock that has heated once be squeezed into swords for fencing.Perhaps adopt somely, become swords for fencing through the direct pressure rolling of multi-pass through a machine porous or multimachine porous to having the roll of different passes.The present invention has reformed ancient handicraft workshop formula and has fallen behind technology, improves the production efficiency of swords for fencing greatly, has improved and stablized outward appearance and inherent quality that swords for fencing is produced, and for having created condition.
Description
A kind of new technology of producing swords for fencing the present invention relates to the metal forming field.
The backward technology of blacksmithing is all adopted in present domestic sports tournament with the production of sword, production, the labour intensity of this handicraft workshop formula are big, production efficiency is low, and product appearance and inherent quality are subjected to the human factor restriction very big, the also therefore normal sword accident of breaking that takes place makes the sportsman cause unnecessary injures and deaths in the match.
The domestic production sports tournament is going out to visit America, is finding in the states such as method, meaning that with Shanghai sports goods one factory of sword various countries also follow ancient workshop explained hereafter swords for fencing.In recent years, because the cheap labour market of China, thereby to the multiplication in all day of China's giver-out-order, it is unremitting that factory should be connect the production of swords for fencing, and for this reason, manufacturer is seeking way in many ways also, and desire changes the backward situation of present production technology.
The objective of the invention is to design a kind of new technology of producing swords for fencing without the handicraft workshop formula, to improve the mechanization that swords for fencing is produced, automaticity, raise labour productivity, improve and the outward appearance and the inherent quality of stable swords for fencing, and create conditions for the foreign exchange earning of this product.
The present invention designs two kinds of schemes and realizes above-mentioned purpose, and the first adopts extrusion forming process.Promptly on the basis of existing extrusion process, change the changeless situation of mould pass in extrusion process, make metal stock in extrusion process, graduate into the mould of swords for fencing shape by pass, and with extrusion molding of swords for fencing.
It two is to adopt direct pressing and rolling process, even also metal stock is in the operation of rolling, by some identical rolls of the hole shape shape of relative position with swords for fencing to being opened on the surface, and the variation of the pass of being opened on each breaker roll surface make blank final after rolling shape and be desired swords for fencing product just.
Now in conjunction with the accompanying drawings the present invention is illustrated.
Fig. 1 is the variable mould extrusion process of a hole shape schematic diagram.
Fig. 2 is direct pressing and rolling process schematic diagram.
Fig. 3 is the schematic diagram of change of shape in the direct operation of rolling of metal stock.
1 is the metal extrusion billet among the figure, the 2nd, and metal base enters the cavity of extruding; The 3rd, the extruding rod, 4 is the variable mould of hole shape of one pair of roller type, 5 for extruding waits in a flash, the identical mould pass of the shape of relative position with swords for fencing.
Fig. 1 is the first scheme schematic diagram of the present invention, and wherein, a pair of rotating extruding running roller is designed to one pair and has pass continually varying mould 4 along one week of wheel rim.In extrusion process, running roller rotates a circle, its girth just in time is designed to and the swords for fencing equal in length, and in the process that running roller rotates a circle, the variation of wheel rim epithyrid is identical with the shape at the relative position of swords for fencing just again, therefore, when producing, as long as the metal stock 1 that will heat is filled in extrusion chamber 2, insert extruding rod 3 then, along with relatively rotating of variable mould 4, metal stock 1 will constantly change shape according to mould 4 continually varying passes, finally after a week is revolved in mould 4 commentaries on classics, be about to blank 1 and squeeze out a swords for fencing.
In this programme; also mould 4 can be designed so that a pair of running roller rotates a circle; squeeze out two swords for fencing or three swords for fencing; the girth that also is about to running roller is designed to the length with respect to two or three swords for fencing; and halve or trisection pass zone along being split into mould one week of 4 wheel rims; in each pass zone; pass must be varied to the shape of swords for fencing gradually; like this; when metal stock 1 in extrusion process; mould 4 relatively rotates a week, promptly squeezes out two or three swords for fencing products.
Fig. 2 is an alternative plan schematic diagram of the present invention, in this programme, adopt some to having the roll of different passes on the surface, the visual sword body length of the logarithm of roll, shape, and the deformability of metal stock and deciding, pass on each breaker roll is different, and it is identical with the shape at the relative position of sword body that its change of shape will be designed to, and also is, the metal stock of heating is in the operation of rolling, rolling by some breaker rolls, its shape changing as shown in Figure 3 promptly is varied to the swords for fencing product gradually, adopt this scheme, aborning, can pass through a machine porous or multimachine porous, directly the metal stock pressure rolling of heating be become swords for fencing through multi-pass.
The present invention also can be used for the production of similar products, namely adopts extruding or pressing and rolling process directly to produce the goods that have the different section shape and size in whole length requirement.
Claims (3)
1, a kind of technology of producing swords for fencing, it is characterized in that, already heated metal stock 1 is become than the roll mould 4 of sword with the relative position of sword shape gradually by a pair of hole shape, once be squeezed into product, the extrusion process middle roll rotates a circle, its girth is identical with swords for fencing length just, and the relative position with sword shape of the hole shape of being opened on the roll mould 4 variation change of shape is identical.
2, a kind of technology of producing swords for fencing is characterized in that, makes already heated metal stock, becomes sword shape by the direct pressure rolling of some rolls to different passes, and it is identical that the variation of different passes is designed to the shape of relative position with the sword body.
3, production swords for fencing technology as claimed in claim 2 is characterized in that, during Rolling Production, can adopt a machine porous, or the multimachine porous becomes product through the direct pressure rolling of multi-pass.
