Abstract
The utility model discloses an automatic centering device for rods. The automatic centering device comprises rollers, material ejection rods, a withdrawing block and a balance wheel; the balance wheel is fixed on a balance wheel seat through a bearing; a tension spring is arranged between the balance wheel and the balance wheel seat; the balance wheel is connected with connecting rods through bearings in a bilateral symmetry manner; slide blocks are connected to the outer ends of the connecting rods through bearings; steel balls are arranged between the slide blocks and slide seats; connecting plates are arranged on the slide blocks; the material ejection rods are fixed at one ends of the connecting plates; a withdrawing roller is arranged at the middle of each of the connecting plates; the upper end of the withdrawing block is fixed on an upper die plate, and the outer side of the lower end is wider than the upper end; and the outer side of the withdrawing block is contacted with the withdrawing roller. The automatic centering device has the advantages that by adopting the device, the accuracy in positioning of rods is improved greatly, and the symmetry degree of products is increased; bearings are arranged at all the rotation parts, so that the clearances of all the rotational connection parts are decreased; and the steel balls are mounted between the slide blocks and the slide seats, so that the flexibility of the slide blocks is improved, and swinging of the slide blocks and the slide seats is reduced.
Description
Technical field
The utility model relates to a kind of spring and produces the raw material detent mechanism.
Background technology
Traditional spring is produced raw material (bar) location and is adopted manual work to lean on the ejector beam location to be placed on the roller bar usually, and the workman judges the bar relative position according to operating experience with feel.It is high to adopt this mode that workman's sense of responsibility is required, and main is that bar is different in size, the unstable product quality of being produced, symmetry is not easy to reach requirement, moulding often appears and after the left-right symmetric degree overproof, have a strong impact on product quality.
The utility model content
The utility model has overcome shortcoming of the prior art, and a kind of bar automatic centring device is provided.
The technical scheme of the utility model is a kind of bar automatic centring device; Comprise roller, ejector beam, give up the throne piece and escapement; Said escapement passes through bearing fixing on the escapement seat; Between escapement and lower bolster, be provided with extension spring, the escapement left and right symmetrically connects connecting rod with bearing, and the connecting rod outer end connects slide block with bearing; Between slide block and slide steel ball is housed; Slide block is provided with connecting plate, and the other end of connecting plate is fixed with ejector beam, is provided with the roller of giving up the throne at the connecting plate middle part; The upper end of the said piece of giving up the throne is fixed on the cope match-plate pattern, and the lower outside width is greater than the upper end width, and the outside of the piece of giving up the throne contacts with the roller of giving up the throne.
Said roller has groove, and groove diameter is greater than the bar diameter.
Compared with prior art, the utility model has the advantages that: adopt this automatic centring device, greatly improved the accuracy of bar location, improved the symmetry of product.Through bearing all being housed, so the gap at the place that reduces respectively to be rotationally connected in each rotation place; And, improved the flexibility of slide block owing between slide block and the slide steel ball is housed, reduced the swing of slide block and slide.
Description of drawings
The utility model will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is the front view when adopting the utility model blowing state;
Fig. 2 is the vertical view when adopting the utility model blowing state;
Fig. 3 is the front view when adopting the utility model work.
The specific embodiment
A kind of bar automatic centring device like Fig. 1, shown in Figure 2, comprising: roller 1, the piece 2 of giving up the throne, escapement 3, extension spring 4, connecting rod 5, slide block 6, ejector beam 7 and the roller 8 etc. of giving up the throne.
Escapement 3 on the escapement seat, is provided with extension spring 4 through bearing fixing between escapement 3 and lower bolster, escapement 3 left and right symmetricallies connect connecting rod 5 with bearing, and connecting rod 5 outer ends connect slide block 6 with bearing.Respectively being rotationally connected the place with the bearing connection, making respectively to connect ensuring smooth transmission, mainly is the gap that reduces between connector, when reducing escapement 3 transmissions as much as possible, drives the range error of slide block side-to-side movement.Four row's steel balls are housed between slide block 6 and slide, main effect be also can flexibility and reliability in the place that oxide skin is arranged use.Slide block 6 is provided with connecting plate, and the other end of connecting plate is conveniently finely tuned with the ejector beam 7 that has been threaded.Be provided with the roller 8 of giving up the throne at the connecting plate middle part; Said upper end of giving up the throne piece 2 is fixed by bolts on the cope match-plate pattern, can about the fine setting, the lower outside width is greater than the upper end width, stand out promptly is the ultimate range that slide block 6 moves.The give up the throne outside of piece 2 contacts with the roller 8 of giving up the throne; The piece 2 of giving up the throne during work moves both vertically with patrix, and when patrix made progress, piece 2 lower outside of the giving up the throne roller 8 that promotes to give up the throne moved laterally; Ejector beam 7 resets; When patrix was downward, the roller 8 of giving up the throne moved in the effect of extension spring 4 to the inside, and ejector beam 7 is to intermediary movements.Roller 1 is processed into and has the groove bigger slightly than bar, and the impression when reducing moulding also has positioning action simultaneously.
Like Fig. 2, shown in Figure 3, the operation principle of the utility model is: at first adjust roller, make left and right sides roller consistent with the distance of middle roller, i.e. a=b; Adjust left and right sides ejector beam again, make that the left side of the right side of left ejector beam, right ejector beam is consistent to the distance of middle roller, i.e. c=d.
When press is in upper dead center position; Manual work is placed on bar 9 on the roller, and patrix moves downward, and drives the piece 2 of giving up the throne and moves downward simultaneously; Escapement 3 is under the effect of extension spring 4; Clockwise rotate, do equidistance motion to the centre simultaneously thereby connecting rod 5 pulling left and right sides slide blocks 6 drive left and right sides ejector beam 7, the ejector beam promotion bar of contact bar one end face moves to the other end earlier; When the ejector beam of the other end also contacted the other end (being the two ends that the ejector beam at two ends all withstands bar) of bar, escapement 3 stopped operating.After moulding was accomplished, patrix moved up, and drove the piece of giving up the throne and moved upward simultaneously, gave up the throne piece in the process of moving upward, and promoted to give up the throne roller 8, drove slide block 6 and moved laterally, and press is in top dead-centre, and left and right sides ejector beam 7 resets, and an operation cycle finishes.
