Abstract
The invention discloses a kind of ω type spring swing type top mold frame, comprise cope match-plate pattern and the upper die body in the middle part of cope match-plate pattern; Upper die body is provided with patrix limited block, the lower end of 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 pressing plate of taper roll bearing covers, and pressing plate holds out against by holding out against screw; The lower end of patrix pawl is provided with patrix roller; The two ends of cope match-plate pattern are provided with adjustment bolt.Good effect of the present invention is: change swing type into by fixed for ω type spring two sequence top mold frame of the prior art, such spring is in forming process, and mould can not extrude the middle part of spring, thus solves the problem of drawing-down in the middle part of spring, reach product design requirement, allow spring stable performance.
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 shaping two sequence top mold frame directly has influence on the drawing-down of the shaping 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.Two sequence top mold frame of use are in the past fixed, in forming process, mould then can not swing outside two, thus make mould extrude 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 the phenomenon occurring 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 in the middle part of cope match-plate pattern; Upper die body is provided with patrix limited block, the lower end of 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 pressing plate of taper roll bearing covers, and pressing plate holds out against by holding out against screw; The lower end of patrix pawl is provided with patrix roller; The two ends of cope match-plate pattern are provided with adjustment bolt.
Compared with prior art, good effect of the present invention is: change swing type into by fixed for ω type spring two sequence top mold frame of the prior art, such spring is in forming process, mould can not extrude the middle part of spring, thus the problem of drawing-down in the middle part of solution spring, 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 (i.e. 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.
Detailed description of the invention
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, adjustment 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:
In the middle part of cope match-plate pattern 13, be provided with upper die body 3, upper die body 3 is fastenedly connected on cope match-plate pattern 13 by soket head cap screw 4; Limited block 8 is fastenedly connected by soket head cap screw 9 by upper die body 3; The lower end of upper die body 3 is provided with adjusting bolt 1, and 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 pressing plate 19 of taper roll bearing 18 covers, 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; Upper die body 3 is connected with end cap 10 by soket head cap screw 11.Be connected with patrix roller 14 in the lower end of patrix pawl 6 by patrix roller shaft 22, patrix roller 14 is locked by locking nut 20 and 21.Be provided with at the two ends (with swing arm 17 corresponding position) of cope match-plate pattern 13 and adjust bolt 15.
When forcing press arrives top dead-centre time, product 16 is placed on position as shown in Figure 1, then top mold frame is down moved, and continue when down moving when patrix roller 14 contact product 16, patrix roller 14 againsts product 16 and down moves, as shown in Figure 3.Continue down in motion process in top mold frame, 14, patrix roller againsts product 16 and down to move and with opening outward (vector motion), a dynamic amplitude is by the clearance control between adjusting bolt 1 and patrix pawl 6.Top mold frame continues down motion, when adjusting bolt 15 and contacting swing arm 17, due to lever principle, the other end (i.e. simmering and bending wheel) of swing arm 17 upwarps, thus carries out simmering and bending to the profile of product 16, until forcing press arrives bottom dead centre, as shown in Figure 4.Then top mold frame up moves, and product 16 is together mentioned by patrix roller 14, and an impulse stroke completes.
Change the gap between patrix pawl 6 and adjusting bolt 1 by adjusting bolt 1, thus control patrix pawl 6 amplitude of fluctuation in the horizontal direction.Down moving in top mold frame drives the patrix roller 14 on patrix pawl 6 to against while product 16 down moves, patrix pawl 6 is with swinging (vector motion laterally, instead of simple down motion), the drawing-down of product medium position can not be made because patrix pawl 6 only down moves.The amplitude that patrix pawl 6 swings laterally, can not can not be shaping because amplitude of fluctuation is excessive then by the clearance control between adjusting bolt 1 and patrix pawl 6.The mechanical processing difficulty of patrix pawl 6 and requirement also corresponding reduction.
