How does the coordinate-piercing press work?

Coordinate-piercing press based on CNC-systemsis more productive in comparison with the models constructed on the basis of the elementary automatics. The developed software products facilitate, and most importantly, speed up the production process. Thanks to the high-resolution position sensors, precision of parts up to 0.005 μm is achieved. Rigid mechanics meets the highest requirements of modernity.

The progress of machine-tool construction

Coordinate-piercing press is the lastthe innovation of machine-tool construction in the field of processing parts by pressure. Widely distributed equipment of this type has been obtained thanks to CNC systems, which allows precise movement of several axes simultaneously. They differ in the accuracy of positioning the working part.

Coordinate-piercing press serves forproduction of holes of any shape in the sheet material. The thickness of the latter depends on the power of the machine and its design. The type of workpiece metal is also taken into account. Soft materials can be selected for greater thickness for processing on the same machine.

Appointment

Coordinate-piercing press serves for working offholes. The shape of the products can be any. It is possible to change the angle of the tool. Under such loads, the rigidity requirements of the structure are increased.

Obtain any contours of products consistentprocessing of several blanks. In a single cycle, you can get a whole series of details from one sheet of material. Coordinate-punching presses with CNC are also used to conduct metal bends of small thickness. It is possible to perform the forming of three-dimensional parts.

Press is indispensable for embossing metalsand alloys of any kind. Marking is similar. But nevertheless, the work of the machine for making through holes is common. The table on which the blank is directly housed has a unique design with cavities. They penetrate the tool after pushing the material.

The speed of piercing the metal sheet is quite high. Optimum modes are selected so that the tool does not begin to age prematurely from excessive loads.

Versatility

Most industries usecoordinate-punching presses. Their prices vary, based on the needs of the customer. The cost of the most simple models begins with a bar in 100 thousand rubles. The base under the workpiece is replaceable and is called a matrix, it is selected for technology.

The shape of the matrix depends on the location of the holes,tool. Pansons pierce the metal sheet with a swift movement of the axis. High pressure helps to obtain ideal products with an accuracy of 0.01 μm.

The punch, as well as the matrix, is made of carbide metals. During processing, they try to take into account and control the wear of the working part.

Automation of the process

Tool for coordinate punching pressescan change automatically. For this, the machine is equipped with a special mechanism, which takes the desired punch from the magazine and inserts it into the holder. The cassette itself can be located directly under the working area of ​​the table, which saves space in the room.

Removable finished small partscan be removed through the hatch, located in the working area on the surface of the table. The extruded part falls under its weight through the open space. Further, the matrix restores the original position, and the process repeats indefinitely, until the machine stops the system at the signal from the finished product counter.

Loading and unloading mechanisms are built aroundthe principle of suckers for thin metal sheets or clamping jaws, pulling thick blanks on rollers. The whole process can be done automatically. The operator's task will be only to ensure the control of the dimensions of the finished parts and the filling up of the loading tray with materials for processing.

Control systems

Coordinate principle of the machine allowedachieve performance of up to 1000 parts per hour and higher. No hydraulic press can match it. The presence of a huge table makes it possible to use workpieces of optimal size. For one loading the machine produces more than a dozen overall products. Conversion to a new type of holes and parameters occurs right during the operation of the equipment.

Taking into account all the advantages, even a new hydraulic press is better to be changed to a coordinate machine, even if it is a second-hand machine. Modern models are equipped with CNC-systems manufacturers:

• Siemens and Heidenhain - quality corresponds to the cost, a huge number of options for a specific production.
• Fanuc - classic and more complex versions, easy to manage, reliable, but at the same time the CNC has limited functionality and often there is no possibility of modernization.
• "Balt-systems" - CNC domestic development, the most economical option, limited functionality.

The most frequently installedsystem. Besides them, there are a lot of other unique CNC-systems. Customers choose for themselves the convenience of use and the principle of homogeneity of parts in production. If the workshop already has a couple of machines on the Fanuc system, it is more rational to install similar equipment on other new models.
