Abstract
The utility model discloses a precision hydraulic combined punching and shearing machine, which is used for punching, shearing and the like for plates and comprises a base, a frame, a die set, a worktable and a supporting platform. The frame is fixed onto the base, the die set is arranged on the frame and the supporting platform, a punch is arranged on the die set, the worktable fixed onto the base is capable of moving relative to the base, a hydraulic clamp for fixing the plates to be processed is arranged at one end of the worktable, a plurality of evenly distributed reset ball devices are arranged on the worktable and the supporting platform, and a pressing plate is fixed onto the die set through a hydraulic pressing device. By the aid of the technical principle of 'high precision and low elastic deformation', the hydraulic pressing device and the reset ball devices are arranged on the punching and shearing machine, elastic deformation caused by instantly generated punching force is reduced, punching precision is improved, and positioning precision of the plates is also improved.
Description
Technical field
The utility model relates to a kind of punching and shearing machine that sheet material is carried out processing such as punching, punching, relates in particular to a kind of hydraulicdriven punching and shearing machine.
Background technology
Along with the appearance of State Council's ten big industry development planning and implementing of a series of measures of expanding domestic demand, China is fast-developing in industries such as shipbuilding, electric power, bridge, automobile, high ferro, lifting transportation, metal structure and each machining factories.The processing capacity of sheet material and section bar also sharply increases in these industries, thereby the punching and shearing machine demand also increasing with certain proportion, yet the type that in industry-by-industry, uses at present almost is the traditional type punching and shearing machine.Tradition punching and shearing machine advantage: can on various shaped steel and sheet material, carry out the punching of multiple function.Also be the first-selected lathe of various shaped steel blanking in enormous quantities, also can carry out bending plate.Tradition punching and shearing machine shortcoming: need manual work to rule during punching, cause processing technology poor, efficient is low.During shearing, because be armstrong's patent formula material pressing device, every shearing once all needs manual adjustment, so efficient is also very low.Domestic for this reason many producers are developing hydraulic combined punching & shearing machine, adopt computer program control to solve artificial line problem, propose to adopt hydraulic drive to replace machine driving, the noise when reducing punching simultaneously.But the hydraulic combined punching & shearing machine that is occurred on the market when punching, because the stamping press that produces in moment is bigger, particularly particularly big to the punching of ultra-thick plate material the time, can produce strain to the sheet material of punching like this, has influenced the punching precision.
The utility model content
The purpose of the utility model provides a kind of precise hydraulic punching (shearing) machine; Adopt the know-why of " high-accuracy, low elasticity distortion "; The hydraulic pressure material pressing device is set on punching and shearing machine and resets roller unit; The strain that the stamping press that reduction produced because of moment brings improves the punching precision, improves the positioning accuracy of sheet material simultaneously.
The utility model is achieved in that a kind of precise hydraulic punching (shearing) machine; Comprise base, frame, die shoe, workbench and retainer platform, described frame and retainer platform are fixed on the said base, and described frame is provided with die shoe; Said die shoe is provided with drift; Described stationary table and can move with respect to base on described base, and it is characterized in that: the end at said workbench is provided with the fixedly hydraulic clamp of machining sheet; Said workbench and retainer platform are provided with several equally distributed roller unit that resets, and on described die shoe, are fixed with holding pad through the hydraulic pressure material pressing device.
The described roller unit that resets comprises the ball base and the ball that resets, at described ball base with reset and be provided with several balls between the ball.
The utility model compared with prior art has following advantage:
1. when carrying out the sheet material stamping-out, along with piston rod movement, the holding pad on the hydraulic pressure material pressing device compresses sheet material prior to punch die, and the hydraulic clamp that is positioned at the numerical control table, NC table vertical plane simultaneously is from the other direction fixed plate.When carrying out stamping-out, sheet material receives the influence of stamping press and produces stretcher strain, and the ball self that resets on the roller unit that resets on the retainer platform this moment can be adjusted sheet material at any time according to the variation of stamping press and stretch the deformation force that produces when alleviating stamping-out.Thereby make sheet material reach the effect of precision positioning, low elasticity distortion.
2. retainer platform and workbench are provided with the roller unit that resets, and can make things convenient for moving of sheet material like this, reduce the tractive force that sheet material moves, and reach energy saving purposes.
