In the metalworking, automotive, part making and molding industries, the industrial press is one of the most vital production equipment. The capacity and performance of these devices directly affect the quality and productivity of the production line. However, due to continuous use, each device needs periodic review and repair. Repairing industrial presses not only prevents major breakdowns and stopping the production line, but also increases the useful life of the device.
In this article, from a technical point of view, we examine the principles of repair, maintenance, and life extension of presses, and at the same time, we introduce the specialized services of Baradaran Rezaei impact presses, which have been operating in the field of overhaul and reconstruction of all types of presses for many years.
The importance and necessity of repairing industrial presses
The press is the main part of the metal forming process. A failure in this device means a complete stop of the production process. The importance of repairing industrial presses can be summarized in a few main points:
- Preventing damage caused by stopping the production line
- Reducing costs due to emergency repairs
- Ensuring operator and personnel safety
- Decreasing depreciation in other mechanical parts
- Improving the quality of production parts
Baradaran Rezaei Impact Press offers a systematic approach in maintaining and renovating devices using expert engineers and precise equipment to minimize production stoppages.
Types of industrial presses and their repair needs
Before starting any repair process, it is important to know the type and structure of the device. Industrial presses fall into three general groups:
Impact presses
This type of press works with the help of flywheel or crank impact energy. Baradaran Rezaei impact press is one of the few centers that performs a complete overhaul of this type of press, including replacing the crankshaft, adjusting connections and precise turning of the parts.
Common failures include the failure of bushings, wear of the main shaft, and misalignment of the shock movement.
Hydraulic presses
The pressure factor in these presses is hydraulic fluid. As a result, problems such as oil leakage, pressure drop and pump failure are common in them. Their repair requires knowledge of hydraulic circuits, pumps and pressure valves.
Pneumatic presses
Pressure is supplied through compressed air. Adjustment of the pneumatic system, control valves and leakage in the lines are among the most important maintenance items.
Basic steps in repairing industrial presses
Repairing presses requires strict and scientific procedures. Baradaran Rezaei Impact Press performs the repair operation using the following step-by-step method:
1. Initial review and detailed troubleshooting
All mechanical, electrical and pneumatic parts are checked by precise tools. This stage includes measurement of slacks, alignment of parts, impact performance and checking of lubrication system.
2. Opening parts and technical washing
After identifying the location of the failure, the main components such as the crankshaft, connections, bushings and the main axis are separated. Parts are washed with special industrial solutions to remove all deposits.
3. Repair and replacement of damaged parts
If possible, the parts are rebuilt by turning and otherwise replaced with standard samples. Rezai Brothers impact press uses standard European and Japanese parts that are highly accurate and durable.
4. Assembly and alignment
At this stage, the parts are assembled with high precision. The level of slide movement and impact pressure are checked with the help of a digital gauge so that the performance of the device is according to the manufacturer's standard.
5. Final testing and delivery
The device is tested under real load and vibration, excess noise and shock performance are checked. Only after the final approval of the quality control engineers, the device will be delivered to the customer.
Industrial press failure warning signs
Understanding the early signs of failure will make repairs at the right time. Below are some of the signs of the need for repair:
- Abnormal increase in noise and vibration
- Decreased impact or press power
- Oil or grease leakage from main parts
- Misalignment of press plates
- Stuck moving parts
If such signs are observed, the experts of Baradaran Rezaei Impact Press are ready to visit and provide a quick technical report.
Preventive maintenance to increase the life of the press
Maintaining the health of the press is not done only by repair, but continuous maintenance plays a fundamental role. The main steps of maintenance are:
- Daily check of oil and grease level
- Checking the status of screws and connections
- Replacing hydraulic filters at specified intervals
- Periodical cleaning of movement paths
- Recording all service operations in the technical office
Baradaran Rezaee Impact Press designs preventive maintenance programs for customers to avoid sudden stoppages.
Equipment used in repairing industrial presses
A professional repair requires precise and standard equipment. In this set of tools such as:
- CNC turning machine
- Hydraulic pressure and flow tester
- High precision digital micrometer
- Laser leveling device for adjusting the press table
- Impact test jack
The presence of this equipment in the workshop Baradaran Rezaei made the repairs to be carried out with higher accuracy than the manufacturer's standard.
Complete reconstruction (overhaul) of industrial presses
When the device has been used for more than 10 years or has several failures, the best option is to perform an overhaul. In this process, the device is fully unlocked, rebuilt and reset.
Baradaran Rezaei impact press in the overhaul section includes the following steps:
- Complete replacement of the main axis
- Crankshaft balance
- Welding and polishing of the table floor
- Resetting the lubrication and electrical system
- Anti-corrosion industrial painting
After the overhaul, the device will have almost the same performance as a new model.
Safety standards in the repair process
Safety principles are very important in the process of repairing industrial presses. Engineers must cut off the power and pressure of the system before any action. The use of safety lock, emergency stop sensor and impact limiter is mandatory.
Baradaran Rezaei Brothers Impact Press performs all repairs based on the ISO 12100 standard and the safety regulations of the Iranian Standards Organization.
Increasing the useful life of the press
By implementing several important principles, the life of the device can be doubled:
- Periodic adjustment of gaps and leaks
- Using suitable and high quality oils
- Installation of oil cooling system
- Preventing overloading beyond the rated capacity
- Performing monthly inspection by an expert
Baradaran Rezaei series of impact presses provides its customers with detailed maintenance instructions and periodic visits so that the machine remains in ideal condition.
