Description
Technical field
The present invention relates to a kind of mechanical press, belong to Machine Manufacturing Technology.
Background technology
At the metal manufacture field, mechanical press is widely used in the processing and forming of metal parts.The tradition punching machine as power source, is realized the moulding of metal blank with the fixed rotating speed motor by crank, slide block mechanism.This existing forcing press, though can be by changing the characteristics of motion that mechanism design changes slide block, but bad adaptability to different Sheet Metal Forming Technologies, can not adjust pressure curve according to the needs of processing technology, lack processing flexibility, and it is little in batches to be difficult to adapt to the product of being processed into, the production requirement that precision is high.
Summary of the invention
The present invention aims to provide a kind of pressure processing precision height, and response speed is fast, regulates the mechanical press of pressure curve flexibility and reliability, and to be processed into product batch little to adapt to modern manufacturing industry, the demand that precision is high.
The present invention realizes that the technical scheme of its purpose is:
A kind of mechanical press comprises motor, screw mandrel, and cross sliding clock, elbow-bar mechanism and vertical slipper, its innovative point is: described motor is servomotor or stepper motor, described servomotor or stepper motor are electrically connected with the PLC Programmable Logic Controller by driver; Described motor is connected with screw mandrel is coaxial; Screw mandrel is connected with the cross sliding clock screw pair; Described elbow-bar mechanism, comprise fork, last connecting rod, the reciprocal connecting rod of lower link and level, wherein an end and the fuselage of fork are hinged, one end of the other end of fork and last connecting rod and an end of lower link are hinged by same jointed shaft, the reciprocal rod hinge connection of the other end of last connecting rod and level, the reciprocal connecting rod of level is connected with cross sliding clock, the other end and the vertical slipper of lower link are hinged, vertical slipper with and the vertical guide rail of fuselage attaching slide equipped, the reciprocal connecting rod of level with and the horizontal guide rail of fuselage attaching slide equipped.
Can understand by above given technical scheme; the present invention is owing to adopt AC servo motor or stepper motor as power source; and implement control by the PLC Programmable Logic Controller; behind program input PLC controller according to the pressure processing craft design compilation; pass through described servomotor of driver control or stepper motor by the PLC controller; realize shutting down or start; at the uniform velocity or not at the uniform velocity; forward or reverse; wait the automatic control of working motion fast or at a slow speed; and then the automatic flexible modulation of realization pressure curve, accurately satisfy the technological requirement of pressure processing, thereby realized purpose of the present invention.
Further innovative point of the present invention is:
Described screw mandrel is a ball screw.Its purpose obviously is further to improve the accurate and degree of flexibility of work of the present invention.
When vertical slipper was cylinder, described vertical guide rail was to have and the be complementary vertical guide rail of through hole of cylinder vertical slipper cylindrical; When the reciprocal connecting rod of level was the pole shape, described horizontal guide rail was to have and the be complementary horizontal guide rail of through hole of the reciprocal connecting rod cylindrical of pole shape level.This is a kind of version preferred for this invention, and it has advantages such as easily manufactured.Certainly, as vertical slipper, it also must have the guiding mechanism that moves up and down, for example keyway pair or the like.
Described motor is connected by Hooks coupling universal coupling is coaxial with screw mandrel.Because the existence of Hooks coupling universal coupling can be avoided the reciprocal connecting rod of described motor and level to be coaxial docking owing to the trouble that both off-centre caused, and can make work of the present invention more flexible.
The upper pendulum bar of described elbow-bar mechanism and fuselage hinged, goes up the hinged of connecting rod and lower link at fork, last connecting rod and the reciprocal connecting rod of level hinged, lower link and vertical slipper hinged, all hinged by oscillating bearing.Described oscillating bearing can make each pin joint of the present invention more flexible, and this not only can make work of the present invention light and handy more flexibly, saves energy consumption, and can further improve the precision of pressure processing of the present invention.
After technique scheme was implemented, what the present invention had was rational in infrastructure, the automaticity height, and pressure processing precision height, characteristics such as the flexible range of work is wide are conspicuous.
Description of drawings
Fig. 1 is the simple and easy diagrammatic sketch of a kind of specific embodiment of the present invention.The reciprocal connecting rod 5-4 of level shown in the figure is connected with cross sliding clock 4, is to adopt the screw that is threaded with cross sliding clock 4 version of the flat reciprocal connecting rod 5-4 active length of the adjustable water saving in the reciprocal connecting rod 5-4 of the level that the is located at tail end elongated slot.By this adjusting, the height in the time of can regulating the job initiation of vertical slipper 8.
The specific embodiment
Please join and read accompanying drawing 1.
