Abstract
The utility model relates to a stroke-adjusting device of a punching machine, comprising a crankshaft, a connecting rod, a connecting rod cover and a needle roller bearing, also comprising a crank throw part, wherein, the crank throw part is integrally connected with a fixed lantern ring and an eccentric lantern ring, is arranged at the crankshaft, rotates with the crankshaft and is matched with the connecting rod and the connecting rod cover with the needle roller bearing; the relative position of the fixed lantern ring and the eccentric sleeve can be changed; the stroke-adjusting device is added on the original punching machine, thus changing the defects that the original punching machine can not change and adjust the stroke and the utilization rate is low, adding the offset of the crankshaft, further expanding the stroke of the punching machine, namely using range of the punching machine, and improving the grade and the utilization rate of the equipment; users can adjust and change the stroke at any time, thus meeting the requirements of continuously replacing moulds and producing different products; the users do not need to further buy equipment to meet the production requirements, thus greatly reducing the load of the users; in addition, the utility model has more convenient use and faster adjustment.
Description
Technical field
The utility model relates to the vitals in a kind of machining equipment, particularly can be used to adjust the punch press adjusting device for travel that the punch press stroke uses in punch press.
Background technology
The existing machinery process equipment, especially forcing press, punch press all are to adopt the offset of bent axle or crank shaft to decide its punching stroke, and its punching stroke all is fixing uncontrollable, therefore the user is when selecting stamping machine, must be according to the size of converted products, the mould that adopts decides the model of buying stamping machine.As in some, small enterprise is few because of its production, product processed quantity various in style, just need to buy the selective use of pressing equipment of many different models, so not only utilization rate of equipment and installations is not high, also increase the burden of factory building storing area and enterprise, also brought inconvenience for simultaneously user's use, maintenance.
Patent No. CN03243083.3 " C type punch press stroke driving control device " is though utilize the groove road that overlaps the protruding rail plug framing inside that is equipped with, for valve barrel traction justifying resultant motion, orientable non-migration is realized the purpose of precision rotating, the collar rotates the height that glides from being a bed hedgehopping with the axle center, so that rotating shaft is hit bottom dead centre in advance and is pressed down formation pressurization power, mould has the certain effect of severing, make the stable precision raising that cuts quality, but it mainly plays stroke location, balanced action, does not also have the stroke adjustment function.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of punch press adjusting device for travel is provided, can adjust the punching stroke of punch press as required at any time, on same punch press, can adjust different strokes, satisfy the requirement of user with different Mould Machining different products, the scope of application and the service efficiency of punch press had both been improved, alleviate the loaded down with trivial details of user's burden and production management again, promoted the class of equipment, practical.
The technical scheme in the invention for solving the above technical problem is: the punch press adjusting device for travel, comprise bent axle, connecting rod, connecting rod cap, needle bearing, also comprise by retaining collar, the eccentric collar and connect into an integral installation and rotate together at bent crank portion of shaft and bent axle, and cooperate with described connecting rod, the connecting rod cap that has needle bearing, the relative position of the described retaining collar and the eccentric collar can change.
Compared with prior art, advantage of the present utility model is: increased this trip adjusting device on original punch press, having changed in the past, punch press can not change, adjust the low drawback of stroke utilization rate, therefore adjusting device for travel has increased the offset of bent axle again, thereby enlarged the punch press stroke is the scope of application of punch press, promoted usage ratio of equipment, the user can regulate as required at any time, the change stroke, satisfying needs constantly the more requirement of mold exchange production different product, make the user needn't purchase more equipment and satisfy the demand of producing, alleviated user's burden greatly, and used more convenient, regulate faster.
Description of drawings
Fig. 1, user mode reference diagram of the present utility model (being installed on the frame of punch).
Fig. 2, structural representation of the present utility model (stereogram).
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Retaining collar 2 is an annular, and the keyway that cooperates with key 1 is arranged on the inwall, and the uniform outer double wedge 14 that extends in is arranged on the rear end face.
The eccentric collar 4 is the eccentric shape of ladder, and its inwall has thick wall part and thin-walled portion, and the uniform outer outer double wedge 15 that extends in is arranged on the eccentric hoop of front end face.
The eccentric collar 4 is enclosed within the crank throw part on the bent axle 5, retaining collar 2 links into an integrated entity by key 1 and bent axle 5, and the double wedge on the retaining collar 2 14 inserts respectively in outer double wedge 15 grooves on the eccentric collar 4 front end faces, mutual chimeric linking into an integrated entity, be fixed on the bent axle 5 by the screw above the retaining collar 2, the outside, junction at the retaining collar 2 and the eccentric collar 4 also fastens the locking collar 3, no longer rotate by the locking collar 3 eccentric collars of locking and retaining collar along bent axle, connecting rod 8 and connecting rod cap 13 usefulness screws link into an integrated entity, cooperate with the eccentric collar, connecting rod 8, on connecting rod cap 13 inwalls needle bearing 7 is installed, front/rear end also is screwed bearing gland 6.
Bent axle 5 is installed on the frame 10 of punch press by the bearing at two ends, and motor is connected (figure does not draw) by belt pulley with flywheel 12, and clutch 11 is installed on the end of bent axle 5, and the saw tooth 9 of connecting rod 8 lower ends is connected with slide block.
During use, motor rotates and drives flywheel 12 rotations, the flywheel overlap joint is gone up clutch, flywheel 12 drives bent axle 5 by clutch 11 and rotates, the rotation that crankshaft crank part is cooperated in conjunction with the offset of the eccentric collar, be transformed into connecting rod 8 drive saw teeth 9 and slide block and do upper and lower linear reciprocating motion, finish the normal operation of punch press.
Be used to produce different products if will change different moulds, just need to regulate the stroke of punch press, at this moment as long as the loosening locking collar 3, again the chimeric retaining collar 2 and the eccentric collar 4 are drawn back and rotate an angle, after reaching required offset, again the retaining collar and the eccentric collar are entrenched togather with the outer double wedge 15 on it, double wedge 14, connect in aggregates, and just can begin by new stroke work with the locking of the locking collar 3, can adjust different offsets as required at any time, satisfy user's different processing requests.
