In forging shop, die forging hammer (including press and other forging equipment) die and hammer are connected by the wedge. In the production process will inevitably encounter a replacement or fastening wedge, the traditional method is to use a heavy lift vehicle hit the head, to knock on the head to obtain a certain speed, both knock on the head by a number of workers to support the promotion, alignment of wedge impact.

Driven drive there are many problems. This method of using driving is unfavorable to the service life of the vehicle; Since the impact head is very heavy, during the fastening process of the wedge iron, it often causes great horizontal vibration of the device itself and greatly affects the life and accuracy of the device; Head in the rocking process is not easy to align wedge tail center, prone to accidents; poor working conditions. Anyang DXT series wedge iron machine just solve this problem.
 
Key driver machine install wedge on forging hammer
 
Key driver machine working principle
The key driver machine is an air driven pile driver. The wedge driver machine is a piston type cylinder with air bag, which moves back and forth by compressed air. When the rear cavity of the key driver machine enters the air and the front cavity is vented, the piston drives the hammer rod and the hammer forward, and the wedge is struck by the guide sleeve. At present, when the cavity enters the air and the rear cavity of the key driver machine is vented, the hammer returns to the piston. The inlet and outlet of the front and rear cavity are realized by reversing the main valve. The right side of the cylinder of the wedge iron machine is equipped with a buffer device to absorb the kinetic energy when the air is empty, and the left end of the cylinder is provided with a throttling buffer device. The following is the pneumatic schematic diagram of the key driver machine:

1. Use the impact head to fix the wedge. When the wedge is tight enough, it can be considered as a whole with the machine. If it is hit again, it will cause the larger transverse vibration of the equipment. This situation can be greatly improved by adopting the key driver machine.
2.Forging workshop to replace the mold, compared with the general method, the use of DXT series key driver machine, will greatly reduce operating time.
3. Due to the traditional method of replacing the wedge iron, the safety factor is not high, and the key driver machine can fix the blow direction so as to ensure the safety of the worker, and at most two people can complete the whole process.
4. Although the main role of wedge iron machine is to hit the wedge iron, in fact, it is an optional directional hammer, therefore, the variant products can be used in any direction against other occasions, such as large-scale forging steel stamping; In another example, the key driver machine equipped with the corresponding auxiliary device can be hit in any direction.
 
At present, Anyang DXT series key driver machine includes the following models, the main technical parameters as shown in the following table:
