Description
Technical field
The present invention relates to a kind of stamping machine.
Background technology
Stamping machine principle is by Motor Drive flywheel, and by clutch, travelling gear drives toggle that slide block is moved up and down, and drives drawing die to steel plate forming.So-called two moving is exactly to refer to that forcing press has two slide blocks; be divided into inner slide and outer slide, the punch of inner slide driven mold or die, the blank holder on outer slide driven mold; in the time stretching, first blank holder moves and pushes down steel plate edge, and inner slide moves and stretches again.
Punching press depended on pressure machine and mould apply external force to sheet material, band, tubing and section bar etc., make it to produce plastic deformation or separation, thereby obtain the forming and machining method of the workpiece (stamping parts) of required form and size.
Punch process is by means of the power of conventional or special pressing equipment, makes plate in mould, directly be subject to deformation force and be out of shape, thereby obtains definite shape, the production technology of the product parts of size and performance.Plate, mould and equipment are the three elements of punch process.
Be divided into drop stamping and cold stamping by punch process temperature.It is high that the former is applicable to resistance of deformation, the Sheet Metal Processing that plasticity is poor; Latter at room temperature carries out, and is the process for stamping that thin plate is conventional.It is one of main method of Metal Forming (or pressure processing), is also under the jurisdiction of forming materials engineering.
Stamping machine is a kind of by Motor Drive flywheel, and by clutch, travelling gear drives toggle that slide block is moved up and down, and drives drawing die to treat the plant equipment of punching parts moulding.
At present, the workpiece in the time that stamping parts is carried out to punching press after punching press is often stuck on grinding tool, needs manually by its perk, sometimes because a large amount of human and material resources that too tightly need to expend of card go to solve.Waste time and energy, and easily cause security incident.
In Chinese Patent Application No.: disclose a kind of stamping machine in 201310249322, comprise the first stamping machine (1), the second stamping machine (2), also comprise steel band feed arrangement (11), the first drawing mechanism (12), workpiece feeding device (21), the second drawing mechanism (22) and conveyer (3); Described steel band feed arrangement and the first drawing mechanism level are arranged on the first stamping machine, and can move with synchronous coordination on the first stamping machine; It is upper that described workpiece feeding device (21) and the second drawing mechanism (22) level are arranged on the second stamping machine (2), and can move with the second stamping machine (2) synchronous coordination; Described conveyer (3) is arranged between the workpiece feeding device (21) on the first drawing mechanism (11) and the second stamping machine (2) on the first stamping machine (1).Its advantage is: this stamping machine project organization is ingenious, being about to two stamping machines is connected mutually by automatic feeding device, realize the object of continuous processing work, not only reduce labour intensity, and improved significantly the production efficiency of product processing, effectively reduce labour's production cost.This technical scheme is easily stuck in the problem on mould after not solving workpiece punching press, haves much room for improvement.
In Chinese Patent Application No.: disclose a kind of stamping machine in 201310126862, comprise body (1), transmission device and decompressor, described decompressor comprises pressing part and sliding part (2), described sliding part (2) can be placed on body (1) up or down, described pressing part is fixed on the bottom of sliding part (2), the top of described sliding part (2) is together with transmission device interlock, under being positioned at described pressing part, pad mould is set, described body is also provided with lifting body and conveying device in (1).When stamping machine operation, whole operating process does not need manual cooperation, but automatically workpiece is delivered in pressing part, and punch process part progressively can be carried backward, until the product that is processed into finished product is delivered to discharging portion, can be by the disposable workpiece finished product that is processed into, this has not only improved production efficiency, and the more important thing is that operation is safer, more convenient, and reduce widely the labour intensity of converted products, thereby effectively saved production cost and labor cost.But, in the time carrying out actual punching press, easily there is the problem that workpiece and mould are stuck, this technical scheme can not solve.
Summary of the invention
