Abstract
The invention discloses an omega type elastic strip oscillating upper die frame which comprises an upper die plate and an upper die body arranged in the middle of the upper die plate. An upper die limiting block is arranged on the upper die body, and the lower end of the upper die body is provided with an adjusting bolt. The upper die body is connected with an upper die jaw through an upper die shaft and a tapered roller bearing, and the upper die shaft is tightly jacked through a jacking screw. The end face of the tapered roller bearing is covered by a pressing plate, and the pressing plate is tightly jacked through a jacking screw. An upper die idler wheel is arranged at the lower end of the upper die jaw, and adjusting bolts are arranged at the two ends of the upper die plate. The omega type elastic strip oscillating upper die frame has the advantages that a fixed omega type elastic strip oscillating upper die frame in the prior art is changed into the oscillating omega type elastic strip upper die frame, and therefore in the process of forming an elastic strip, a die will not extrude the middle of the elastic strip, and the problem that the middle of the elastic strip is pulled to be thin is solved. The product design requirement is met, and therefore the performance of the elastic strip can be stable.
Description
Technical field
The present invention relates to a kind of ω type spring swing type top mold frame.
Background technology
In process of production, the structure of moulding two order top mold frame directly has influence on the drawing-down of the moulding medium position of spring to ω type spring, and product drawing-down directly has influence on the quality of product, makes the fatigue behaviour of product not reach technical requirement.The two order top mold frame that used are in the past fixed, in forming process, mould can not swing outside two, thereby make mould extruding spring, cause the material footpath drawing-down of spring medium position, do not reach product design requirement, in use, due to stressed, drawing-down position, middle part is also easy to occur the phenomenon of fracture.
Summary of the invention
In order to overcome the above-mentioned shortcoming of prior art, the invention provides a kind of ω type spring swing type top mold frame.
The technical solution adopted for the present invention to solve the technical problems is: a kind of ω type spring swing type top mold frame, comprises cope match-plate pattern and the upper die body at cope match-plate pattern middle part; On upper die body, be provided with patrix limited block, lower end at upper die body is provided with adjusting bolt, on upper die body by mold shaft and taper roll bearing be connected with patrix pawl, upper mold shaft holds out against by holding out against screw, the end face of taper roll bearing covers with pressing plate, and pressing plate holds out against by holding out against screw; Be provided with patrix roller in the lower end of patrix pawl; Be provided with adjustment bolt at the two ends of cope match-plate pattern.
Compared with prior art, good effect of the present invention is: by the fixed swing type that changes into of ω type spring two order top mold frame of the prior art, spring is in forming process like this, mould can not push the middle part of spring, thereby the problem of solution spring middle part drawing-down, reach product design requirement, allow spring stable performance.
Accompanying drawing explanation
Examples of the present invention will be described by way of reference to the accompanying drawings, wherein:
Fig. 1 is the front view (being fundamental diagram one) of this top mold frame;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the fundamental diagram two of this top mold frame;
Fig. 4 is the fundamental diagram three of this top mold frame;
Fig. 5 is the fundamental diagram four of this top mold frame.
The specific embodiment
A kind of ω type spring swing type top mold frame, as depicted in figs. 1 and 2, comprise: adjusting bolt 1, locking nut 2, upper die body 3, soket head cap screw 4, hold out against screw 5, patrix pawl 6, upper mold shaft 7, patrix limited block 8, soket head cap screw 9, end cap 10, soket head cap screw 11, hold out against screw 12, cope match-plate pattern 13, patrix roller 14, adjust bolt 15, product 16, swing arm 17, taper roll bearing 18, pressing plate 19, locking nut 20, locking nut 21, patrix roller shaft 22 etc., wherein:
Be provided with upper die body 3 at cope match-plate pattern 13 middle parts, upper die body 3 is fastenedly connected on cope match-plate pattern 13 by soket head cap screw 4; On upper die body 3, by soket head cap screw 9, limited block 8 is fastenedly connected; Be provided with adjusting bolt 1 in the lower end of upper die body 3, adjusting bolt 1 is fastened on upper die body 3 by locking nut 2, and adjusting bolt 1 can regulate the amplitude of fluctuation of patrix pawl 6; Patrix pawl 6 is connected on upper die body 3 by upper mold shaft 7 and taper roll bearing 18, upper mold shaft 7 holds out against by holding out against screw 5, the end face of taper roll bearing 18 covers with pressing plate 19, pressing plate 19 holds out against by holding out against screw 12, and the play of adjustable patrix pawl 6, patrix pawl 6 is between adjusting bolt 1 and patrix limited block 8; On upper die body 3, be connected with end cap 10 by soket head cap screw 11.Lower end at patrix pawl 6 is connected with patrix roller 14 by patrix roller shaft 22, and patrix roller 14 is by locking nut 20 and 21 lockings.Be provided with at the two ends of cope match-plate pattern 13 (with swing arm 17 corresponding positions) and adjust bolt 15.
When forcing press arrives when top dead-centre, product 16 is placed on to position as shown in Figure 1, then top mold frame is down moved, when patrix roller 14 contact products 16, and while continuing down to move, patrix roller 14 is pasting product 16 and down moving, as shown in Figure 3.In top mold frame continues down motion process, 14, patrix roller is pasting product 16 and is down moving and follow outward and open (vector motion), and a moving amplitude is by the clearance control between adjusting bolt 1 and patrix pawl 6.Top mold frame continues down motion, when adjusting bolt 15 while contacting swing arm 17, due to lever principle, the other end of swing arm 17 (being simmering and bending wheels) upwarps, thereby the profile of product 16 is carried out to simmering and bending, until forcing press arrives bottom dead centre, as shown in Figure 4.Then top mold frame up moves, and patrix roller 14 is together mentioned product 16, and an impulse stroke completes.
Change the gap between patrix pawl 6 and adjusting bolt 1 by adjusting bolt 1, thereby control patrix pawl 6 amplitude of fluctuation in the horizontal direction.When top mold frame is down moved and is driven patrix roller 14 on patrix pawl 6 pasting product 16 down to move, patrix pawl 6 is followed and is swung laterally (vector motion, rather than simple down motion), can not make the drawing-down of product medium position because 6 of patrix pawls down move.The amplitude that patrix pawl 6 swings is laterally by the clearance control between adjusting bolt 1 and patrix pawl 6, can not moulding because amplitude of fluctuation is excessive.The mechanical processing difficulty of patrix pawl 6 and also corresponding reduction of requirement.
