A kind of manufacture method of hub by integrally shaping
The manufacture method of the present invention's step and a kind of hub by integrally shaping.
Be the colored hub of saw lumber in the prior art with the metal solid material, its manufacture method all be usually utilize the forging mode with the each several part assembly make one by one finish after, rely on the mode of welding that the each several part assembly is given combination again, make it become a complete colored hub, perhaps directly utilize the mode of turning to give car and make a flower hub.The colored hub that really utilizes above-mentioned method to produce to have practicality, but wherein still exist many defectives, owing to utilize existing mode manufacturing flower hub, the time compole that processing is consumed is long, so cost height just, produce in a large number and not meet economic principle.In addition, utilize existing method processing flower hub, must purchase expensive special mechanical equipment, this originally with regard to not high product, owing to high cost investment, will inevitably reduce this competition capability for economic benefit.
Purpose of the present invention is just in order to solve outside the deficiency of the prior art, and proposed a kind of hub by integrally shaping manufacture method.Its method is to be saw lumber with the metal solid material, and through manufacture processes such as cut-out, extruding and borings, can produce integrated colored hub apace.The method not only is suitable for general a large amount of production, and more can produce a colored hub that inside is closely knit and structural strength is extremely strong.
The objective of the invention is that full pattern realizes:
The hub by integrally shaping manufacture method comprises following making step:
1. the manufacture method of a hub by integrally shaping comprises following making step
A. get the material program: need select round strip solid metal material for use according to specification;
B. cut off program: should justify strip solid metal material and be cut off, and insert in the mould for further processing use by the finished product length requirement;
C. push program: place mould to give up and down clamping location the solid metal material that is cut out, the addendum cone that then utilizes this inside, mould left and right sides more respectively from about advance and held fixingly, carry out extrusion modling;
D. drilling program: the colored hub of outward appearance moulding is got out by the left and right central hole that ejects run through axis hole.
Purpose of the present invention can also be further perfect by following steps:
The hub by integrally shaping manufacture method is inserted one and is rolled program between steps A and step B, utilize the patrix of motionless counterdie and motion circumferentially to roll out arc groove on the solid metal material.
The present invention compared with prior art has following advantage: at first, the method not only is suitable for general a large amount of production, and more can produce a colored hub that inside is closely knit and structural strength is extremely strong; Secondly, owing to need not use expensive plant equipment, so small investment, instant effect.
The present invention has 8 width of cloth accompanying drawings, and wherein Fig. 1 is the best processing route figure, also can make the accompanying drawing of specification digest.
Fig. 1 is a process block diagram of the present invention;
Fig. 2 cuts the generalized section of back solid metal material for the present invention;
Fig. 3 waits for the generalized section that is held the location up and down for solid metal material of the present invention;
The generalized section that Fig. 4 carries out the extrusion modling operation for solid metal material of the present invention;
The planar appearance figure of Fig. 5 colored hub finished product for the present invention manufactures;
The planar elevation view that Fig. 6 carries out the roller-compaction operation for solid metal material of the present invention;
The planar side view that Fig. 7 carries out the extrusion modling operation for solid metal material of the present invention;
The planar appearance figure of Fig. 8 colored another embodiment of hub finished product for the present invention manufactures.
Below in conjunction with accompanying drawing best implementing process of the present invention is described further:
Optimum process method of the present invention has the following steps:
A. get the material program: need select round strip solid metal material (for example aluminium alloy) for use according to specification;
B. cut off program: should justify strip solid metal material and be cut off, and (as shown in Figure 2), insert in the mould for further processing use by the finished product length requirement;
C. push program: place mould 2 to utilize upper and lower mould 21 to give clamping location (as shown in Figure 3) up and down the solid metal material 1 that is cut out, the addendum cone 221 that then utilizes these mould 2 left and right sides moulds 22 inside more respectively from left and right advance held fixing, push (as shown in Figure 4), impel the outward appearance of colored hub to be extruded moulding (as shown in Figure 5) fully; Be worth this one carry be because metal material 1 of the present invention be solid material,, so be different from traditional forging so more Gong crimping section is arranged, become a colored hub that inside is closely knit and structural strength is extremely strong.
D. drilling program: the colored hub 3 of outward appearance moulding by the left and right centre bore that ejects 31 places, is utilized drilling machine to get out and runs through axis hole 32.
It should be noted that if will make as shown in Figure 8 another kind flower hub 4 time, increase by one procedure of processing wherein just must be between last rapid A and step B, more shown in Fig. 6,7.This strip solid metal material 5 is cutting to suitable specification, just send in the mould 6 in advance, the counterdie 61 of this mould 6 maintains static, patrix 62 then can be done shift reciprocately, and patrix 62 bottom surfaces design tool gradient on direction of advance, add the protuberance 621 that upper edge length of material direction forms predetermined number again, when operation, as long as this strip solid metal material 5 is placed on this, counterdie 62,61, the action of this patrix 62 can promote this metal saw lumber 5 and roll action, and utilize on it each protuberance 621 of institute's moulding in this metal saw lumber 5, to make predetermined number arc groove 51, so as long as proceed aforesaid B again, the step of C and D can produce the colored hub 4 that as shown in Figure 8 outward appearance has arc.
