Abstract
The utility model discloses a forming die used in a machining method of a high-strength transverse-8-shaped work-piece. The forming die comprises an upper die plate, an upper die fixed on the upper die plate, a lower die plate, and a lower die fixed on the lower die plate. The upper die is provided with an upper die cavity, the lower die is provided with a lower die cavity, and the upper die cavity and the lower die cavity form a transverse-8-shaped inner cavity in a matching mode. A guide plate and a pair of locating rods moving relative to the guide plate are respectively arranged on the portions, matched with the cavity portions on two sides of the middle position of the lower die cavity, on the lower die. The locating rods are clamped between the guide plate and the inner wall of a metal pipe. The forming die solves the problems that machining accuracy and strength of an existing die are difficult to guarantee and the manufactured transverse-8-shaped work-piece is not long in service life, and can meet customer needs well.
Description
Technical field
The utility model belongs to the metal stamping manufacture field, especially relates to a kind of shaping mould for high strength " ∞ " font spare (as connecing in the chain) processing method.
Background technology
The utility model processing method prepared " ∞ " font spare is an important union piece on the chain, is mainly used on the high-power machinery chain chain, and its precision and intensity are determining quality and the life-span of whole chain.Existing processing method is divided into welded type and cast type, and the processing step of welded type is flat web blanking → pre-fold → bending → secondary bending → correction → solder up.This processes process is long, and operation is tired many, often also do not reach requirement in delivery, and welding performance is poor, and workpiece is not easy to reach specification requirement, and the life-span of chain can not get guaranteeing.If the employing cast type, not only processing cost is higher, and efficient is low, is prone to the defective that pore, pockmark etc. have a strong impact on intensity behind the casting thin-wall.In order to overcome the problems referred to above, the inventor has invented and a kind of radially transversal metal tube has been heat-treated, and on forcing press stamping forming method, obtain a kind of high strength " ∞ " font spare.
The utility model content
The purpose of this utility model provides a kind of shaping mould for high strength " ∞ " font spare processing method, has solved existing mold machining accuracy intensity and has been difficult to guarantee, " ∞ " the font spare not long problem in service life that makes.
The technical scheme that its technical problem that solves the utility model adopts is: the shaping mould that is used for high strength " ∞ " font spare processing method, comprise cope match-plate pattern, be fixed on the patrix on the cope match-plate pattern, lower bolster and the counterdie that is fixed on the lower bolster, patrix is provided with upper cavity, counterdie is provided with lower mode cavity, and upper cavity and lower mode cavity cooperate the internal cavity that forms " ∞ " font; The both sides cavity in adaptive lower mode cavity centre position is respectively arranged with a pair of backstay of guide plate and relative guide plate activity on counterdie, and this backstay is stuck between guide plate and the inner wall of metal tube.
Preferably, the guide plate outside also is provided with support column, is provided with the stage clip of control support column stroke between support column and lower bolster, and backstay is placed on the support column; Further, lower mode cavity is the groove of one and half " ∞ " font, is provided with convex tendon in the middle of the groove, and guide plate is positioned at the two ends of convex tendon.
For aperture and the pitch that guarantees chain link, improve the precision of processing, the diameter of backstay is suitable with the aperture of " ∞ " font spare.
Discharging for convenience fixedly has one group of first dnockout rod that is used for moving back part on the cope match-plate pattern; Lower bolster is provided with one group of second dnockout rod that is used for moving back part, and one group of rubber clamping plate that make the resilience of second dnockout rod; Described first dnockout rod and second dnockout rod are suitable with backstay.
In order to guarantee that process is milder, guide plate is and the integrated guide plate of counterdie.
The beneficial effects of the utility model: in metal tube, penetrate backstay, when patrix is descending, backstay rolls downwards along the guide plate edge, finally fall into the internal cavity of " ∞ " font, this mould has solved existing mold precision intensity and has been guaranteed, " ∞ " the font spare not long problem in service life that makes; Further, be provided with the support column of settling backstay in the guide plate outside, guarantee that punching course is more stable, make things convenient for the employee to operate; The diameter of backstay is suitable with the aperture of " ∞ " font spare, has guaranteed aperture and the pitch of chain link, improves the precision of processing; At cope match-plate pattern and lower bolster one group of dnockout rod is set, prevents that effectively " ∞ " font spare is stuck on patrix or the counterdie, has made things convenient for discharging.
Below with reference to drawings and Examples, the utility model is carried out comparatively detailed explanation.
