Description
Technical field
This utility model relates to a kind of punch press, a kind of punch press utilizing cam to replace slider-crank mechanism.
Background technology
Punching apparatus is mainly used in the punching press of sheet material, punching, blanking, bending flanging, molding, drawing, finishing, fine, shaping, riveting and extrusion etc., it is widely used in every field, such as industries such as wrist-watch, toy, tableware, telecommunication apparatus, motor, electrical equipment, automobile, haberdashery and hardware, radio, traditional slider of punch is driven by bent axle, it is difficult to be changed at work process slide block movement track, slide block movement is short to the lower dead center time of staying, the demoulding time product generation elastic deformation, easily affect the molding of product, cause Workpiece shaping irregular.
Summary of the invention
For the deficiencies in the prior art, this utility model provides the flexible punch press by cam drive of a kind of good forming effect.
nullThe technical solution of the utility model is: the cam drive of a kind of flexible punch press，Including lower roller、Cam、Upper roller、Lower roller seat、Contiguous block、Traveller guide pin bushing、Traveller、Slide block、Upper roller bracing frame、Connect guide pillar、Lower roller block bracket、Motor、Belt pulley、Belt、Camshaft、Flywheel、Clutch，It is provided with motor shaft on described motor，It is provided with belt pulley on described motor shaft，Described belt pulley is connected with the flywheel arranged on the clutch by belt，Described camshaft is arranged on the clutch，Described upper roller is arranged on connection guide pillar by upper roller bracing frame，Described upper roller is connected with the cam being arranged on camshaft，Described lower cam end is connected with lower roller，Described lower roller is arranged on lower roller seat，Described lower roller seat is arranged on connection guide pillar by lower roller block bracket，Described lower roller seat is connected with traveller by contiguous block，Described traveller is arranged in traveller guide pin bushing，It is provided with slide block in described traveller.
Described cam is constant diameter cam.
Described cam structure is curved profile structure, the all strings of a musical instrument through center of described cam contour are equal, described cam contour includes top dead-centre dwell regions, down stroke region, bottom dead centre dwell regions, up stroke region, wherein said top dead-centre dwell regions, bottom dead centre dwell regions are the circular arc with cam center as the center of circle, radius is respectively R1, R3, cam angle degree corresponding to top dead-centre dwell regions, bottom dead centre dwell regions is identical, and the stroke of described slide block is determined by top dead-centre dwell regions, bottom dead centre dwell regions, i.e. S=R1-R3.
Down stroke region is the rise of cam, when cam rotates, drives lower roller to move downward, thus drives slide block movement to bottom dead centre, thus complete press work；Up stroke region is the backhaul of cam, and when cam rotates, in driving, roller moves upward, thus drives slide block movement to top dead-centre.
Motor is rotated by belt drives flywheel, thus drives clutch to rotate together with camshaft, and camshaft band moving cam rotates, and actuated by cams lower roller moves up and down, and lower roller is driven through traveller thus drives slide block to move up and down.
The beneficial effects of the utility model are: this punch press is moved up and down by actuated by cams slide block, so that slide block slows down ram speed when entering stamped area, solve when slide block in punching course moves lower dead center without stopping and the problem of excessive velocities, thus avoid stamping products irregular problem, greatly reduce percent defective, substantially increase production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure, the upper roller of 1-, 2-cam, 4-lower roller, 5-lower roller seat, 6-contiguous block, 7-traveller guide pin bushing, 8-traveller, 9-slide block, 10-upper roller bracing frame, 11-connects guide pillar, 12-lower roller block bracket.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model is described further:
nullAs shown in Figure 1，A kind of cam drive of flexible punch press，Including lower roller 1、Cam 2、Upper roller 4、Lower roller seat 5、Contiguous block 6、Traveller guide pin bushing 7、Traveller 8、Slide block 9、Upper roller bracing frame 10、Connect guide pillar 11、Lower roller block bracket 12、Motor、Belt pulley、Belt、Camshaft、Flywheel、Clutch，It is provided with motor shaft on described motor，It is provided with belt pulley on described motor shaft，Described belt pulley is connected with the flywheel arranged on the clutch by belt，Described camshaft is arranged on the clutch，Described upper roller 1 is arranged on connection guide pillar 11 by upper roller bracing frame 10，Described upper roller 1 is connected with the cam 2 being arranged on camshaft，Described cam 2 lower end is connected with lower roller 4，Described lower roller 4 is arranged on lower roller seat 5，Described lower roller seat 5 is arranged on connection guide pillar 11 by lower roller block bracket 12，Described lower roller seat 5 is connected with traveller 8 by contiguous block 6，Described traveller 8 is arranged in traveller guide pin bushing 7，It is provided with slide block 9 in described traveller 8.
Described cam 2 is constant diameter cam.
The structure of described cam 2 is curved profile structure, the all strings of a musical instrument through center of described cam contour are equal, described cam contour includes top dead-centre dwell regions, down stroke region, bottom dead centre dwell regions, up stroke region, wherein said top dead-centre dwell regions, bottom dead centre dwell regions are the circular arc with cam center as the center of circle, radius is respectively R1, R3, cam angle degree corresponding to top dead-centre dwell regions, bottom dead centre dwell regions is identical, and the stroke of described slide block is determined by top dead-centre dwell regions, bottom dead centre dwell regions, i.e. S=R1-R3.
