Shown in Fig. 3,4, be a kind of schematic top plan view and schematic side view of conveyer in the past.This conveyer 1 is board 19 front sides neighbour and be hung with a solid seat 11 of axle and a clamping fixture seat 12, and at this clamping fixture seat that is wholely set 12, axle solid seat 11 left and right sides ora terminalis and board 19 corresponding positions, borrowing connecting rod rocking arm 13 to articulate respectively links, has similar quadric chain with formation, when power source with the operator when 18 pass this clamping fixture seat 12 back and forth, can drive the solid seat 11 of axle in the lump by this connecting rod 13, clamping fixture seat 12, on the left and right directions shown in Fig. 3 drawing, swing back and forth, wherein, because of other mechanisms of conveyer pass through multi pack to be located at this

board

19,12 of solid seat 11 of axle and clamping fixture seats, and, processing procedure be equiped with many groups because of but needing the impact forging device, only lift one group herein and be used as explanation, it comprises: actuating mechanism 14, push up go back to mechanism 15, leverage 16 and clip claw mechanism 17, wherein, actuating mechanism 14 has a cam 141 that is arranged on the board 19, cam 141 can be subjected to drive power source and rotate, be provided with startup rocking arm 142 in its side, it has and is subjected to end 143 and strikes and support to hold 144, be subjected to 143 to be subjected to cam 141 contacts all the time, hold 144 to swing up and down with it and make to strike to support to end; This top time mechanism 15 is installed in strikes under end 144, is pneumatic cylinder structure, and its bottom has charged compressed air, makes the piston rod 151 corresponding pushing tows that make progress; This leverage 16 has the driving rocker 161 that is hubbed on this solid seat 11, and driving rocker 161 has intermediary's end 162 and driving end 163, and intermediary's end 162 is to overlap on this to strike between end 144 and piston rod 151 tops; This clip claw mechanism 17 is packed in clamping fixture seat 12 front sides, it has the main shaft 171 of upright shafts pivot on clamping fixture seat 12, main shaft 171 tops are the driving ends 163 that pivotly join driving rocker 161, its bottom is transmission one folder axle 172 then, this folder axle front end is equiped with the jig arm 173 of a pair of staggered pivot joint, and each jig arm below is linked with jaw 174.When pinching start, start power source and make cam 141 rotations, when the not protruding top of cam 141 starts being subjected to when holding 143 of rocking arm 142, piston rod 151 pushing tow that can make progress relatively, and with this intermediary's end 162 and strike to support to hold and push away on 144, make this driving end 163 to lower swing, descend with the main shaft 171 that drives in this clamping fixture seat 12, and, make this to jig arm 173 pivots pendulum, and make this closed relatively this embryo spare of clamping of jaw 174 via this folder axle 172 of transmission.And when cam 141 rotates to the protruding startup rocking arm 142 in top, then pass through the interlock of a succession of mechanism after, can make main shaft 171 rise making jaw 174 revolve breakdown and put.And in the motion flow of anchor clamps lifting clamping, also must cooperate the mobile step of important transmission, and just on 18, back and forth pass this clamping fixture seat 12 with a power source the operator in addition, jaw 174 can be transmitted in the inter-agency dealing of each impact forging by clamping embryo spare.

Though above-mentioned conveyer in the past can be finished the work that clamping transmits embryo spare, has following disappearance under actual operation:

(1) set structural rigidity deficiency, the restriction of clamping fixture seat passes speed:

By finding out among Fig. 3, the span of this clamping fixture seat 12 is long, and it is by connecting rod rocking arm 13 unsettled this board 19 front sides that are hung on that are positioned at two ends, therefore the not enough easily deflection deformation of its rigidity, what especially the driving end 163 of rocking arm 161 was carried out is the strength that acts on down vertically upward, the clamping fixture seat 12 of crossing long span bears this indirectly vertically to active force, to between reciprocal operation, produce shake because of rigidity is not enough, this shake directly influences the clip claw mechanism 17 of installing on the clamping fixture seat 12, cause the embryo spare of its clamping also to rock easily, especially when an end of the long cun screw of clamping, rocking of whole screw will be more serious, further cause pinching the public affairs of impact forging, in the time of between master mold, embryo spare can't accurately be aimed at the forging center line, and produces substandard products.Because the above-mentioned factor of rigidity deficiency that causes can cause substandard products, so the speed of reciprocating action can not be too fast, limited speed of production relatively, influence the integral production ability.

(2) push up back that mechanism's extending space is less, limit production speed:

The pneumatic cylinder that mechanism 15 is gone back on this top is to be installed in intermediary's end 162 and to strike under the piston rod 151 of end 144, as shown in Figure 1, because of the forging in each stage must limit to some extent with the distance between the male and female module, to shorten the distance that anchor clamps pinch back and forth, therefore each pushes up go back to

mechanism

15,15 ', 15 " it also is limited waiting space apart; therefore the accommodation space of reserving is less; so its pneumatic cylinder specification that can install (or spring specification) is also limited relatively; at this intermediary's end 162 of contact and strike to holding 144 o'clock; less towards pushing away butted power; that the strength of clamping embryo spare is also less, thereby has limited speed of production, influence production capacity.

(3) anchor clamps travelling backwards The limited time, influence quality:

Each of clip claw mechanism 17 is driven folder axle 172 by this of its correspondence separately to jig arm 173, and this can fold up embryo spare along with the swing of jig arm 173 to the jaw 174 that jig arm 173 bottoms are connected, this clip claw mechanism must pinch embryo spare to each flow process in regular turn again, to be connected the operation of each flow process, so it must be in the solid embryo spare of last die clamp in certain moment, then be displaced to next mould and when punch die, loosen embryo spare, since the work flow that " pinches-loosen " back into row, and after this is pinching embryo spare to jaw 174 the master mold place of predetermined impact forging, must head on punching press and when coming at the male model drift, open jaw 174 and decontrol embryo spare, so that the corresponding impact forging embryo spare of drift, if and this embryo spare shape has head as shown in Figure 2, this jaw 174 just must in time open before head collides and be next, make the diameter can be smoothly by finishing punching press greater than the head of wire rod, avoid jaw 174 by collsion damage, and this open jaw 174 more transmits another embryo spare for the displacement that can continue is back to last mould district with clamping, therefore must wait until that this male model withdraws from earlier before embryo spare in a segment distance and the die cavity is not pushed out as yet, promptly take advantage of when vacateing the space between male model and master mold, these jaws 174 just can back be displaced to last master mold place, just push up go back to mechanism and eject the outer embryo spare of master mold, carry out next transmission flow process to continue to connect double-layered quilt.

Therefore, above-mentioned conveyer must be after waiting for that a segment distance is withdrawed from this male model impact forging, and the ability travelling backwards is to carry out the operation that a time clamping transmits, and the time that therefore can be used to travelling backwards will be very limited, it must be with the speed travelling backwards that is exceedingly fast, and causes influencing the operation quality of its material folding.
