Installation of the foundation of the machine is necessary for the operation of technological equipment, it is important to accurately calculate and prepare the basis for its installation. Each type of equipment has its own purpose, is able to perform specific functions, has characteristics peculiar only to it. The weight and size of the equipment, the loads acting on it, the vibration created during the operation affect the choice of the foundation for the future machine.
The foundation should serve as a reliable base of the machine, ensuring the maximum use of its capabilities in performance and accuracy during a given service life and eliminating the impact of the machine on the operation of neighboring equipment. To do this, it is necessary that the foundation, with convenient placement and strong fixing of the machine, meets the requirements for ensuring the rigidity and vibration resistance of the machine and limiting the level of vibrations transmitted from the machine.
According to the conditions of strength, almost any soil can serve as a reliable natural foundation, since at the size of the foundation, selected from the conditions of placement of the machine, the pressure on the base usually does not exceed 5 N / cm2. The strength of the elements of the foundation construction at the real size and structural forms of the foundations of the equipment is also usually provided with a margin.
The requirements for the foundations according to the criteria of rigidity and vibration resistance of the machines of different types installed on them are different and are determined by the impact of the installation on the performance of the machines.
The effect of the installation on the accuracy of processing and the quality of the treated surface is determined by the level of relative static movements and fluctuations of the tool and part, different under different installation methods. In heavy machines, with insufficient rigidity of the foundation, processing errors are significant due to deformations of the stan-foundation system under the influence of the weight of the moving nodes of the machine. Forced oscillations, the intensity of which depends on the machine installation, determine the appearance of distortions in the shape of the processed parts, in particular the appearance of wavy.
The impact of machine tool installation on performance is manifested in the fact that with a more rigid installation, machining is possible at higher modes and higher cutting stability.
The effect of the installation on the durability of the machines is determined by an increased rate of wear due to a violation of the correct contact in the guides and an increase in oscillations, as well as the “shattering” of threaded connections during intense fluctuations.
Lathe, revolver, grinding and some other machines installed on the floor without reconciliation and fastening, after a short time lose accuracy and require repair.
Features of installation of foundations under machines:
Installation of machines on the foundation has a direct impact on the performance of the equipment.We offer you installation of equipment on the foundations of several types:
- concrete floors of the 1st floor (installation on the general slab of the workshop);
- thickened concrete tapes (installation on a tape foundation);
- specially designed concrete foundations, including piles and vibration-insulated structures.
- other
Foundations on springs
Foundations on springs are the most perfect, but also the most expensive means of vibration insulation.
The advantages of foundations on springs are determined by the features of springs, namely:
- steel springs allow large static elastic movements (up to 350 mm), therefore, with the help of springs, very low frequencies of the vibration-insulated installation can be obtained;
- springs can be precisely calculated and constructed to obtain any given (linear and nonlinear) characteristic;
- They can work at different temperatures, the creep of steel springs is negligible.
Foundations on springs have been used for vibration insulation of machines for a long time, and the issues of their calculation and design are quite well developed and successfully used in our projects.
Machine tools on the foundations can be installed as follows:
- with fastening on anchor bolts, that is, on special wedges, provided that the supporting surface of the cement wall is filled;
- on adjustable support elements without pouring cement;
- without bolt mounting with the filling of the supporting surface of the wall with solution;
- without bolt mounting with the filling of the supporting surface of the wall with solution;
- on elastic supports.
Fixing is also used using bolts installed in wells on ready foundations.
In most cases, blank foundation bolts are used. A certain spread also received tsang bolts
On how strong and reliable the base will be, the duration of uninterrupted operation of the equipment depends. Entrusting the installation of the foundation of the company “Sintez TMK”, you can be sure of strict compliance with the requirements specified in the RRP, and obtaining a reliable base for the installation of any structures.
Depending on the need, various works can be proposed:
- Preparation of a project for the manufacture of the foundation;
- Leveling of the site, dismantling of existing buildings;
- Geodetic research and planning of the place under the foundation;
- Various earthworks;
- Manufacture of the foundation using metal structures, plates of metal or concrete;
- Leveling of the surface, setting horizontally in level;
- Installation of bolts and other foundation fasteners;
- Quality control, finishing the foundation.
It is necessary to prepare the place for any equipment, especially for machines that produce vibration during operation. The construction team can perform the installation of the base according to the project, but if any problems arise, it becomes necessary to make adjustments during the work, which requires special knowledge and skills.
Installation of the base can be quite a difficult task, requiring high accuracy and the use of special equipment. Specialists of our company are highly qualified and have experience of various kinds of work, know the special requirements for foundations for various equipment, so any task will be performed perfectly.
For the customer, the main task is the normal operation of the equipment, and therefore the preparation of the foundation for it should be trusted by professionals. Our arsenal has equipment for lifting loads, preparing and leveling sites, installing the base, but no less important is the experience and special training of specialists capable of performing work of any complexity.
A feature of our offer is an integrated approach to installation work, when the installation of the foundation is part of a complex of other works, and therefore all the actions of workers are coordinated with each other. At the same time, maximum efficiency is achieved at the optimal cost of work.
