ABSTRACT
It is a simple mechanism which can bend the TMT bars by putting very less amount of efforts. In industry, there are many tasks in which you have to bend. There are so many mechanisms developed to perform such functions. The main problem in all these mechanisms is they require an external power supply. And they are also bulky and expensive. Here we are manufacturing the simplest, chipset and self-powered bender. It can bend the same amount of load as that of a conventional bender. This bend is not only for industrial use but it can be used anywhere like agricultural, domestic use etc.
INTRODUCTION
Using the mechanical bending process some problems as listed below:-
1. Leverage required for bending heavy sections is large; hence a tremendous amount of human effort is necessary.
2. Labor cost is more.
3. Time-consuming, in terms of setting time ad operation time.
4. Space occupied is more.
5. Quality is not good.
6. Defects in the form of angular deformation and wrinkles are seen.
Conventional mechanical process is replaced by the hydraulic system which offers many benefits
2.2 SOLUTION:
Hydraulic automatic bending. is a perfect solution to the above problem wherein bending force is generated is quite large about (0.5 ton) with a minimal human effort.
The hydraulic automatic bending uses a hydraulic pump mechanism to apply a gradual force up to 5000kg. Loading is done by operating handle of the jack which carries the cutting action, resulting in a safe and damage free operation.
In order to increase the speed of operation, the pneumatic circuit is used to operate the hydraulic pump and the relief valve and return spring set will help the quick return of hydraulic ram, thereby reducing the idle time of the machine.
APPLICATIONS OF HYDRAULIC TMT BAR BENDER
Hydraulic benders are a versatile mechanism and are found in any shop, garage or maintenance department. They provide hands-free operation in both horizontal and vertical positions to perform bending, pressing or work-holding applications. Few applications listed below.
1) Tmt bar bending.
2) Construction sides.
3) Fabrication shops.
ADVANTAGES OF HYDRAULIC TMT BAR BENDER
• Consistent and repeatable operation.
• Controlled bending forces.
• Automatically adjusting work supports.
• Remote bending operation.
DISADVANTAGES OF HYDRAULIC TMT BAR BENDER
1) Not suitable for a very heavy load.
2) angular not so suitable.
