China's die forging industry has developed rapidly in recent years and has taken its place in the world market. However, it is still in the stage of “is a big country not a strong countryâ€. The fiery economy in the past few years has concealed the vision of China's die forging industry. The focus of investment is on the excessive expansion of the scale of ordinary products, and the proportion of investment in the field of precision forging is very high. small. The suppression of overheating development has given us enough time to think. I believe that in the next few years, there will be no better time for a big profit that can only be achieved through the expansion of volume. I want China's die forging industry to completely enter the world's advanced production areas. The road to precision forging is a rare opportunity for every smart enterprise and a plan for the future.
Precision forging, that is, precision die forging, mainly includes two aspects. One is to refine the blank, that is, to replace the rough cutting process by the precision forging process, such as the closed precision hot forging car gearbox, the remaining amount is 0.6~1mm, tolerance ± 0.4. The second is precision forging parts, that is, precision net forming forging technology, which directly obtains finished parts by precision die forging, such as cold precision forged car planetary and semi-axle gears, star sleeves, etc., which can reduce or eliminate the post-forging machining process. Precision die forging has the advantages of significant energy saving, environmental protection, high quality and high efficiency. Because of this, all countries in the world are vigorously developing precision die forging, which includes cold, warm, hot and composite precision die forging. The future development trend is hot or warm forging and cold finishing combined forging technology, thus obtaining a larger weight. Forgings with complex shapes and high dimensional accuracy.
The equipment guarantees the forging quality and production efficiency as the preconditions, that is, it satisfies the forging forming process requirements, and the production efficiency is suitable for batch requirements.
The specific requirements for precision equipment for forgings are as follows:
1. Equipment rigidity and slider guiding accuracy are high to ensure high precision for forgings.
2. The pressure work stroke is long. Precision die forging is mostly extruded and has a long working stroke.
3. The size of the mold space is large, and multi-station forging is realized.
4. The forging out mechanism has a long delay.
5. High production efficiency.
While grasping the equipment, we will develop our own process team to provide users with a package of services, including process consulting, mold design and manufacturing, auxiliary machine supply and robot configuration, etc., which can provide turnkey services for users. Improve the level of automation, to achieve a press is a production line, a person is a production line level.
On the host side, we have mainly improved and improved the following points:
1. Increasing the use of tonnage of hot forging presses to improve and perfect the important parts of the machine tool on the basis of the original design, so that it can meet the user's safe full-load use, and can allow the continuous use of the nominal tonnage 1.25 times, expanding The range of forging forces, such as 1600 tons of hot forging presses, can be used up to 2,000 tons.
2. Increasing the nominal pressure stroke The general pressure stroke of the hot forging press is only 3~5mm. We increase the nominal pressure stroke to 10mm, which expands the scope of use of the machine tool, which can increase the hot extrusion stroke and can be used. Formed by warm forging.
3. Add “removing the boring vehicle deviceâ€
It can meet the problem of improper operation of the machine and can be easily released without damaging the machine tool and the mold.
4. Improve the lower top material system, increase the ejection force, and adjust the ejection stroke and time.
5. The work surface is hardened. The work surface of the press is sunken after long-term use, which causes great trouble for the user. We harden the work surface to achieve a surface hardness of more than HRC30, effectively solving the problem of recessed work surface.

Ni-Cd Battery Emergency Exit Sign
These emergency exit signs usually equipped with recharged a 3.6V Ni-cd battery inside the hosing. It has up to 500 times backup powered. The battery is protected by a low voltage cut-off circuit. Also, the emergency escape signs specialized to use the fire-resistant housing at the engineering level. Upon failure of the normal utility power, an internal transfer switch provides emergency time for at least 90 minutes. The charger initiates powered back the battery in 24 hours. The exit sign is suitable for wall or ceiling mounting. Plus, there is an indicator light and a test button on the unit so that you can periodically check that it is functioning properly.
