Description

8 connecting rod punch presses
Technical field
The utility model relates to a kind of 8 connecting rod punch presses.
Background technology
At present, find in the technical process of thin plate deep drawn, the speed that mechanical press's slide block of common toggle runs in drawing process, acceleration are comparatively large, the part in drawing and forming are easily torn or wrinkling, the qualification rate of tensioning member is low, and the waste product caused is more.The mould that punch press uses is larger at the temporary impact of upper and lower mould matched moulds, the parts and components of main frame, mould is damaged, thus cause main frame, mold use service life reduction, and the load operating region stroke of crank punch press is shorter, is not suitable with the requirement that deep stretching process load operating region is long.Defect on these punch press main machine structures strongly limit the development of deep stretching process.
Summary of the invention
The utility model is the needs of the technological work such as the industrial sheet such as the automobile that be not suitable for high speed development, light industry punch forming, deep drawn of mechanical press in mechanism solving toggle punch press, a kind of mechanical type 8 connecting rod punch press is provided, make drawing hourly velocity low and evenly, and no-load speed is fast, productivity ratio is high, and stretching depth is large.
For achieving the above object, the utility model is achieved through the following technical solutions:
A kind of 8 connecting rod punch presses, include frame, transmission, slide block, balancer, mobile trolley used, die-cushion, described frame includes footstock, middle abutment body, base, reinforcing bar and alignment pin, footstock, middle abutment body, base is closed framework by described four reinforcing bar pretensions, middle abutment body and footstock, base is located by described alignment pin, described transmission includes motor belt transmission, the gear drive of high speed level, three grades of deceleration transmission of slow speed turbine stage gear drive composition, 8 push and pull system, guide pillars and bushes, described 8 push and pull system include eccentric body, upper connecting rod, angular pole, angular pole axle, lower link, speed control rod and master connecting-rod, eccentric body is driven by slow speed turbine stage transmission, described angular pole is connected by angular pole axle and footstock, master connecting-rod lower end and guide pillar connect, guide pillars and bushes coordinates, guide pin bushing is fixed in footstock bottom surface, described slide block includes worm gear case, and described worm gear case is fixed on slide body, and connects with the guide pillar in transmission, described balancer is fixed in the left and right sides of footstock bottom surface, lower end and slide block affixed, describedly mobile trolley usedly be positioned at submounts, described die-cushion is fixed in base.
Operation principle of the present utility model is: frame is closed framework by footstock, column, base with four pull bar pretensions, meet the pretightning force of needs during punch ram and certain rigidity requirement, column and crossbeam, base are located by alignment pin, ensure the accurately reliable of fuselage ring.Transmission is divided into three grades of decelerations, and the first order is motor belt transmission, and the second level is the gear drive of high speed level, and the third level is slow speed turbine stage gear drive.Slow speed turbine stage gear drive drives eccentric body, upper connecting rod, angular pole, 8 push and pull system motions of lower link, speed control rod, master connecting-rod composition, can drive guide pillar, thus band movable slider do asymmetrical movement by this system, that is: pull down time delay speed low and even, and upwards no-load speed is fast.Slide block is connected with the guide pillar in transmission mechanism by the worm gear case be fixed on slide body, and make slide block under the drive of transmission mechanism, the guide rail along column side pumps, and eccentric body often rotates a circle, and slide block just moves up and down once.The Main Function of balancer is balance slide block parts, patrix and the weight such as connecting rod, guide pillar, the gap of the force part such as push and pull system, worm gear case can be eliminated, avoid in the upper and lower stroke of slide block, the additional impact power caused because of gap commutation, ensure that slide block movement steadily and punch press stable accuracy, prevent brake failure from causing slide block to conduct oneself with dignity the safety in utilization of the contingent accident that glides, guarantee punch press, in addition, the rapid recovery of flywheel energy is also contributed to.Mobile trolley usedly can facilitate user's quickly replacing mould.Die-cushion is when punch press stretches, and plays the effect of flanging and discharging, when punch press carries out blanking, plays the effect of liftout.
The utility model has the advantage of: 8 connecting rod punch press drawing hourly velocity are low and even, and no-load speed is fast, and productivity ratio is high; And stretching depth is large; In the speed allowed, 8 connecting rod punch press drawing depths are maximum reaches 320mm, and general crank punch press only has about 70mm; 8 connecting rod punch presses can realize large ram travel length with less eccentric throw, better meet the needs of drawing process needs and automation loading and unloading; And 8 connecting rod punch presses effectively can reduce the impact to mould in the course of the work, improve the mold use life-span.

Detailed description of the invention
In conjunction with Fig. 1-2, a kind of 8 connecting rod punch presses, include the parts such as frame, transmission, slide block 3, balancer 2, mobile trolley used 5, die-cushion 6.Described frame includes footstock 1, middle abutment body 4, base 7, reinforcing bar 8 and alignment pin 9, and footstock, middle abutment body, base are closed framework by four reinforcing bar pretensions, and middle abutment body and footstock, base are located by alignment pin.Described transmission includes motor belt transmission 10, high speed level gear drive 11, slow speed turbine stage gear drive 12 3 grades of deceleration transmission, 8 push and pull system 13, guide pillar 29, guide pin bushing 28.Described 8 push and pull system include eccentric body 21, upper connecting rod 22, angular pole 23, angular pole axle 24, lower link 25, speed control rod 26, master connecting-rod 27, eccentric body is driven by slow speed turbine stage transmission, angular pole is connected by angular pole axle and footstock, master connecting-rod lower end and guide pillar 29 connect, guide pillars and bushes 28 coordinates, and guide pin bushing is fixed in footstock bottom surface.Described slide block includes worm gear case 14, and described worm gear case is fixed on slide body, and connects with the guide pillar in transmission.Described balancer is fixed in the left and right sides of footstock bottom surface, lower end and slide block affixed.Describedly mobile trolley usedly be positioned at submounts.Described die-cushion is fixed in base.
Can be found out by the rate curve of Fig. 3 slide block, slide block moves downward in operation interval speed lower and be approximately uniform motion, low-speed motion can reduce the distortion of material effectively, meet the requirement of Sheet Metal Stamping Process to speed, effectively can improve the quality of profiled member: meanwhile, owing to decreasing the dynamic load of system, thus improve the mold use life-span, reduce the noise impacting and produce, optimize working environment.In addition, when it can also be seen that slide block idle stroke by the speed curve diagram of slide block, movement velocity is higher, and have anxious characteristic of returning, the circulation timei of the operation of slide block shortens greatly, and the operating efficiency of punch press is greatly improved.
Above embodiment is only case of the present utility model, and any replacement done according to the utility model spirit is all interpreted as not departing from protection domain of the present utility model.
