KHF700 Hydraulic Fine Blanking Machine

KHF700 Hydraulic Fine Blanking Machine

General Description:
Hydraulic Fineblanking Press is not a standard stamping press. Fineblanking presses are unique by providing three specific motions: a stinger motion, which brings the stinger plate up and holds the material in place during blanking; a blanking motion, which provides the blanking force to push the part into the die cavity; and a counter pressure motion, which holds the piece against the blank punch during blanking and ejects the piece part from the die cavity after blanking is complete. KHF 700 Hydraulic Fineblanking Press is characterized by wider worktable, higher accuracy, efficiency and reliability.

Features:
1. Overall welded frame structure guarantees the lightness and stability of the fine blanking machine.
2. Hydraulic Fineblanking Press is driven by simple-structured cylinder to ensure the enough power driving and protect the sliding block from bending and deforming.
3. Concisely designed with single pump, single motor and power accumulator of high capacity, our power system features low power consumption, high efficiency, and less malfunction.
4. The blanking speed, the pressure as well as the back pressure can all be adjusted on the control panel due to the adoption of accurate rotation control technology.
5. The advanced and creatively-designed mold installment technology can realize convenient exchange of the molds.
6. Equipped with protection device, the pressure and position of Hydraulic Fineblanking Press can be flexibly adjusted to keep the molds from accidental damage.
7. Not only can feeding and discharging be automatically controlled, but also the parts and wastes can be distinguished automatically.
8. The latest touch-screen numerical control system of Hydraulic Fineblanking Press contributes to simple operation.

Products

Advantages:

1. Low cost:
Our Hydraulic Fineblanking Press can make the sheets into parts with single blanking manufacturing process needed, while maintaining the accuracy. Therefore, the cost can be significantly reduced.
2. High accuracy:
KHF series Hydraulic Fineblanking Press can ensure the dimensional accuracy and smooth cross during the whole process which involves drilling, milling, grinding, etc.
3. Well-designed Structure: 
a. Overall welded structure of our fine blanking machine guarantees lightweight and good rigidity.
b. Long surface connected with guard rail makes the machine maintain vertical even under higher pressure coming from side loading.
c. Adjustable block is mounted at the bottom of the main cylinder to guarantee accurate positioning of the Hydraulic Fineblanking Press.
d. Control system characterized by proportional adjustment and accumulator of high capacity offers faster fine blanking and low energy consumption.
4. Tooling installation room:
The manufacture of large-size and complex stamping products is available due to the installation of composite continuous tooling room.
5. Isolator:
Isolator can not only make the machine look more beautiful but also reduce the noise. The installment of working platform on Hydraulic Fineblanking Press guarantees convenient maintenance and operation safety.
6. Tooling protection:
Timely tooling protection can be provided due to sensitive feedback scanning system, which can identify the parts not removing and then stops the sliding immediately.
7. Feeding system:
a. Both sides of the machine are mounted with feeding system to guarantee feeding efficiency.
b. Hydraulic Fineblanking Press’s height can be adjusted up and down based on the specific production requirements.
c. The feeding system incorporates guiding function to insure multi-station punching.
8. Waster shears:
A strong hydraulic waste shear is installed in the rear of the feeding unit to deal with the waste after stamping. Specifically speaking, on one hand, the holddowns are equipped between the feeding unit and waste shear to ensure not to flip when shearing materials. On the other hand, the guide plate can provide reliable guide when the material pass the waste shears and the cutting can be set on the panel.
9. Control technology:
(1). KHF series Hydraulic Fineblanking Press mainly adopts our self-developed CNC system and imported PLC controller. The feeding mechanism also makes a good use of PROFIBUS communication, with which PLC communicates so that the high precision reaching 0.01 can be realized.
(2) The operation lies in the combined efforts of operator data showed in the screen and the test of physical data (pressure and path). Meanwhile, the control system also can conduct diagnostic and monitoring functions.
