Description
Technical field
The utility model relates to the press technologies field, the stepless self-regulation structure of particularly a kind of stroke of a press amount.
Background technology
Whether the punching machine of home and abroad use at present is variable according to path increment; Be divided into fixed forcing press of stroke and stroke adjustable pressure machine; Through retrieval; Stroke adjustable pressure machine mainly is that single-point crank throw forcing press is many at present, and the crank throw formula stroke adjustable pressing machine of producing at present mainly is to regulate the adjustable purpose of eccentric throw realization ram travel amount through regulating eccentric bushing.But owing to regulate the eccentric bushing structure all is configuration card toothing on eccentric bushing, and artificial the rotation regulated.And that eccentric bushing is contained in connecting rod is inner, and lathe eccentric bushing when work can generate heat with the connecting rod connecting portion, and the working time has been grown and can cause the bad adjusting of swelling of generating heat of eccentric bushing and connecting rod.Secondly, locking with bent axle after eccentric bushing has been regulated is to lean on the latch structure, and the size of latch can not be too little; Otherwise can not satisfy the requirement of strength of transmitting moment of torsion; The latch size can not be too big, because the latch radius size is fixed, the size of each latch increases; Total number of teeth is with corresponding minimizing, and it regulates progression also just seldom like this.So, realize that automation and serialization that the stroke of a press is regulated require to be extremely important.
The utility model content
The utility model provides a kind of stroke of a press amount stepless self-regulation structure to the problem that prior art exists, and makes the ram travel of forcing press realize stepless continuous, regulate automatically.
The purpose of the utility model is achieved in that the stepless self-regulation structure of a kind of stroke of a press amount, comprises eccentric shaft, eccentric bushing and connecting rod; Said eccentric shaft is supported in the fuselage supported hole through support set; Said eccentric bushing is fixedly connected with eccentric shaft through the swelling cover, and said connecting rod and eccentric bushing outer planet are dynamically connected, and said eccentric bushing one end is provided with the eccentric throw adjusting device; The said eccentric bushing other end is provided with encoder; Said eccentric shaft is provided with inductor, and said inductor is used to measure eccentric bushing and the eccentric shaft relative angle changes, and said encoder is used for going out the path increment of slide block and passing through display output according to the angle conversion that inductor records.
In the utility model; Eccentric bushing and eccentric shaft fix by the swelling cover; The relative angle of eccentric bushing and eccentric shaft can be regulated arbitrarily; Ram travel can be regulated arbitrarily between maximum and minimum of a value, compares with latch locking mode of the prior art, and ram travel is improved to stepless any adjusting from there being level to regulate; Encoder and inductor can change according to the relative rotation of eccentric bushing and eccentric shaft to be measured the ram travel amount automatically and on display, shows, and like this, has improved the precision of regulating greatly.Therefore compared with prior art, the beneficial effect of the utility model is: the path increment stepless continuous that can realize forcing press is regulated, and adjustment process is controlled automatically; Need not manual adjustments; Degree of regulation is high, improves automation degree of equipment, has enlarged the scope of application of equipment.
Improvement as the utility model; Said eccentric throw adjusting device comprises adjusting gear, and said adjusting gear one end is provided with spring, and the other end is provided with piston; Said piston is arranged in the piston ring; Said spring is fixed with regulating ring gear through pressing plate, and said eccentric bushing is provided with feather key with regulating the corresponding periphery of ring gear, and said piston and spring are used to control to adjust gear and regulate the ring gear engagement and separate.When needs adjusting slider stroke, the swelling cover unclamps, and eccentric bushing and eccentric shaft can be relatively rotated, and the offset sum of the relative eccentric shaft main rotating shaft of eccentric bushing and eccentric shaft line is the half the path increment of slide block; Piston intake; Promoting adjusting gear overcomes the spring force effect and regulates the ring gear engagement and fix through feather key and eccentric bushing; Eccentric bushing and adjusting gear relative fixed like this, and can in regulating ring gear, rotate, when eccentric shaft rotates; Adjusting gear drives the eccentric bushing counter-rotating, realizes eccentric bushing and relatively rotating of eccentric shaft and carries out the adjusting of ram travel amount.When adjusting finishes, the piston exhaust, spring promotes that adjusting gear separates with the adjusting ring gear and adjusting gear skids off from feather key, make between adjusting gear and the eccentric bushing to relatively rotate, and realizes normal ramming motion.This structure is when regulating; The power that eccentric bushing rotates relative to eccentric shaft is from the rotation of bent axle, and its power is considerably beyond the power of manual adjustments, thereby can not have the problem that is difficult to regulate because of connecting rod and eccentric bushing heating swelling; Make the stroke adjustment of forcing press time saving and energy saving, easy to operate.
As a kind of improvement of the utility model, said swelling is set on the end of eccentric bushing, is provided with cinch bolt in the swelling cover.When adjustment stroke, cinch bolt unclamps, and makes eccentric bushing and eccentric shaft to relatively rotate, and carries out stroke adjustment; When adjusting finishes, the cinch bolt of screwing makes the swelling cover that eccentric bushing and eccentric shaft are locked, and realizes the ramming motion of just using always.
