Modern mechanical engineering has a limited, park of the most diverse high-performance equipment: foundries, hammers, presses, machine tools and automated lines.
Each of these types of equipment is the most effective in the manufacture of a certain type of products, each indispensable in its field of technology.
Crooked presses are intended, as a rule, for forgings during mass and large-scale production, should ensure the manufacture of forgings with a lower metal consumption (compared to steam-air stamping hammers) and minimal allowances for subsequent machining.
Unlike steam-air stamping hammers, crank presses allow you to automate the production of forgings, which ensures increased labor productivity and reduced cost of forgings, reduces vibration and noise.
An increase in the technological complexity of crank presses, an increase in the cost of their repair and maintenance pays off in the subsequent operation.
One of the main tasks in the design and manufacture of presses is to increase the reliability and efficiency of all components and parts of the crank press: crankshaft, rod, slider and guide, gears.
There are the following types of crank presses:
Crystal presses for bulk stamping:
Fraud presses for sheet stamping:- horizontal forging machines;
- cold landing machines;
- minting presses;
- Hot stamping and special presses.
- Presses of simple action - are intended for cutting, flexible, shallow hood and have one slider;
- Double-acting presses - such presses have two sliders: external, serving for cutting and pressing the workpiece, and internal - for drawing;
- Triple-action presses have three sliders. They carry out a particularly complex hood.
Dismantling of the crank press
Measures to dismantle the crank press include such types of work:
So this is the scheme of dismantling the crank press.- Carrying out dismantling works on equipment;
- Dismantling work on the foundation of the device;
- Packaging and preservation of individual units and systems of crank press;
- Moving with the help of special rigging devices and loading equipment on the vehicle (low-feed platform, car trailer, railway transporter, etc.);
- Transportation of the crank press to the installation site;
- Carrying out unloading works of the crank press at the delivery point and redeploying it using the rigging press to the assembly point.
- Installation of the crank press.
Fraud press rigging
In terms of the volume of activities performed, rigging and transportation of crank presses is a movement belonging to the category of oversized cargo with a large weight, so all restrictive measures associated with non-standard transportation of goods must be observed here.
As for the rigging of a crank press, its fastening on a mobile cargo platform and the nature of the use of lifting mechanisms when loading on low-frame platforms or trawls depends on its weight and linear dimensions, the state of the roadway along which the crank press will be transported and other factors affecting the safety of equipment during movement.
The carrier undertakes to issue travel documents and special transportation permits.
Installation of the crank press
At the point of installation, the crank press equipment is released from packaging and packaging, and the units and mechanisms prepared for storage are subject to deconservation and thorough wipe.
By means of visual control, the absence of defects, porcelain bushings on the primary output contacts are checked, air dehumidifiers, oil filters, liquid indicators are checked, the integrity of the seals of the manufacturer is checked.
Identified defects are corrected during installation work.
Initiation of the crank press
Start-up crank press is used to test the main characteristics of the product and its components before the start of the operating period.
To perform commissioning works, the Customer allocates his representative authorized for the prompt resolution of organizational and technical issues.
The list of equipment and tools necessary for carrying out the PNR is available from service engineers of Sintez TMK.
After the completion of the commissioning, the machine is checked according to the Certificate of Acceptance for Conformity with Technical Specifications, after which the relevant Act on executed PPR is drawn up.
According to the results of commissioning, the Customer is put into operation equipment corresponding to passport data.
Regulatory instruments
Regulatory documents that must be guided for dismantling, rigging, transportation and installation and commissioning of crank press:
GOST 12.3.009-76 “SSBT”. Loading and unloading work. General safety requirements”
Guide to fastening technological equipment with foundation bolts (CH 471-75)
GOST 24379.0-2012.Basic bolts. General technical specifications.
SNIP 3.05.05-84 Technological equipment and technological pipelines
VSN 362-87 Manufacturing, installation and testing of process pipelines up to 10 MPA
SN 527-80 Instructions for the design of steel pipelines up to 10 MPA
Collection E26 Installation of technological pipelines
We will professionally produce a rigging hot-roll crank press in Moscow and the Moscow region, we also have partners in All Russia and the CIS countries, and will dismantle the hot-roll crank press, install the foundation for a hot-roll crank press, implement the maintenance of hot-roll crank press and its modernization.
