Transfer Press
We use Link-Drive mechanism in our Transfer Presses. It is suitable for shaping medium and deep shaped workpieces in operations where displacement-tonnage performance of eccentric presses is not sufficient.
We produce link drive presses in two connecting rods and four connecting rod configurations.
In industrial standards, PLC, operator panel, cam case, clutch brake valve, clutch brake, encoder and light barriers are selected from globally accepted brands.
Our presses are PLC controlled. We use safety PLC or safety modules in accordance with 2006/42/EC regulation. Depending on the size of the press, we use 9” or 12” rotary console operator panels.
Prescription-based press speed adjustment and regulation adjustment can be made with the encoder from the operator panel.
We manufacture our presses with fixed or mobile plate and cushioning according to your request.
Our gears are zero-gap herringbone gears.
Body Structure
Mono-block body or tension shaft body can be designed according to the design inputs.
In both body structures, the maximum deflection at the mold connection points is 0.12 mm/m.
The structure should be pre-tensionedwith tensioner shaft-column.
The tension nuts should be self-tensioning. It can be removed by applying pressure without the need for additional equipment.
The body is obtained by welding St52-3 quality plates.
Welding is performed by certified welders using SG3 welding wire.
After welding, the body is placed in the furnace and subjected to stress relieving process.
Body Design
Body design is analyzed with Ansys finite element software. Design improvements are maintained until an infinite fatigue life is achieved in the analysis.
The results obtained are presented to our customer with a report.
Mechanism design
The motion curves obtained by various mechanisms provide different advantages and disadvantages in each process.
In the design of the mechanism, it starts with the selection of the appropriate curve.
The high course required in transfer presses and a soft slope towards the end of the course are often provided by the link-drive mechanism.
A mechanism suitable for the formability of the parts to be formed is designed and then optimized by kinematic analysis and numerical methods.
Kinematics
During the process, the parameters of velocity, position, and acceleration are optimized within the limits allowed by the mechanism to properly direct the flow occurring in the material.
While aiming the most appropriate movement curve for the process, it is ensured that the forces to be applied to the mechanism legs and bearings are kept to a minimum.
Power Train Design
By using the results obtained from the mechanism design and kinematic data, the designs of the powertrain are carried out.
Analysis
In our designs, we use the finite element method to estimate how the powertrain behaves. We use ANSYS software for these analyzes we perform in the computer environment.
ANSYS, one of the modern simulation software, contains the finite element method on its basis. It helps us find the weakest point in our designs and make parameter optimization.
Slide Guiding
The ram is guided on the columns from 8 surfaces.
Each plate is precisely adjusted and secured by means of bolts in the x and y directions.
Optimized lubrication channel and precision machined bronze bearings work on steel plates.
Clutch & Brake
Pneumatic or hydraulic clutch type is used.
Depending on the press speed, mechanism and operating conditions, the clutch type is selected.
The required clutch and brake size are calculated according to the transmitted power, torque, tonnage and speed information.
Clutch- The brake is controlled by a double valve control system with monitoring, three-way safety.
Shut Height Adjustment and Overload Protection
The shut height adjustment is achieved by the movement of the nuts working on the thrust bolts.
In our presses, the shut height adjustment and overload protection systems are combined in a single body.
In case of a situation exceeding the press limits during any possible mould failure and mass production, the hydraulic overload valve is activated and possible damage is prevented.
Moving Bolster
One of the most important components of the transfer press is the mobile tables. The way to minimize mould fastening and setting time is to use double mobile table presses.
We manufacture electric motor, hydro motor or air motor driven mobile tables.
We place the mobile table lifting cylinders into the lower bridge. In the same way, we position the centering and locking assemblies in the lower bridge.
We also manufacture mobile tables with shaft holes in presses equipped with air-cushion.
2 Direction Moving Bolster
After the mobile table is out of the press, in some cases, the first movement direction must also move vertically.
We solve this need with 8-wheeled mobile tables. Press shop floor remains level again. 4 wheels to work for the second movement direction remain hidden inside in the first stage. When it comes to the direction change zone, it is activated and provides movement.
Option: Traveling Clamp
It is an SMED application used for automatic and fast connection of the upper mold to the press ram.
Preston mould retainers provide faster setup.
Each has a capacity of 6-8-10 tons and a 600 mm or 800 mm advance course.
Receives the plate presence/absence information and transmits it to the PLC.
Continuously checks the pressure, completes the missing pressure.
It gives an emergency warning in case of incomplete status.
