Automatic Mold Locking, Monitoring, and Control System for Fine Blanking Presses
Fine blanking presses are currently widely used in automotive parts manufacturing and the processing of complex parts, and are also suitable for the processing of small and medium-batch stamping parts. For mass production fine blanking presses, the dies need to be regularly replaced and repaired; for small and medium-batch production fine blanking presses, the frequency of die replacement is higher. Under normal conditions, the dies need to be locked by manually disassembling and tightening nuts. The locking force is difficult to control, and it takes about 1 hour to replace a die; the labor intensity of installing the die is high; manual operation often leads to poor die centering, poor contact between the die and the worktable, which directly shortens the life of the die, and in severe cases, the die may even loosen during operation, causing personal injury to the operators, and there are considerable safety hazards.
Therefore, it is necessary to improve the existing die positioning, die locking system, and safety and reliability of fine blanking presses to improve the automation level of fine blanking presses, shorten the die change time, reduce the labor intensity of operators, eliminate equipment and personnel safety hazards, and improve equipment utilization.
During normal operation of the fine blanking press, abnormal die positions are also fed back by sensors or switches, and the protection program is activated, greatly improving the safety of the equipment. A locking cylinder piston is installed in the surface of the lower worktable of the fine blanking press; a guide pin and a spring are installed on the lower end surface of the locking cylinder piston, and a lower locking rod is installed in the upper T-shaped groove. The locking cylinder piston, its guide pin, spring, and lower locking rod are connected to the stepped surface of the stepped hole of the lower worktable by a clamping ring and fasteners.
A support roller is also installed in the surface of the lower worktable of the fine blanking press. Below the support roller is a small plunger cylinder. The small plunger is connected to the pressure plate and end cap by fasteners on the stepped surface of the stepped hole of the lower worktable; the small plunger can move up and down under the action of the lower oil pressure, and the support roller moves up and down with the movement of the small plunger.
Side guide seats are installed on both sides of the upper end surface of the lower worktable of the fine blanking press, and the side guide seats are connected to the upper surface of the lower worktable by fasteners. There are multiple recesses on the inner side of the side guide seat, and rollers are installed in the recesses. Several sensors are also installed in the surface of the lower worktable of the fine blanking press.

What are the characteristics of a hydraulic press?
CNC hydraulic oil pumps generally use internal gear pumps, while traditional hydraulic presses generally use axial piston pumps. At the same flow rate and pressure, the noise of an internal gear pump is 5 dB to 10 dB lower than that of an axial piston pump. The motor of a CNC hydraulic press runs at rated speed during pressing and return, and its noise emission is 5 dB to 10 dB lower than that of a traditional hydraulic press. When the slider rapidly descends and is stationary, the servo motor speed is 0, so the CNC hydraulic press has essentially no noise emission.

Application scope and system selection of small hydraulic presses
Suitable applications for small hydraulic presses include: 1. Punching various silicone and plastic buttons for mobile phones or remote controls, and cutting plastic products; 2. Cutting various protective films for mobile phones, digital cameras, and laptop LCD screens, as well as precision cutting and halving of various pressure-sensitive adhesives and trademarks; 3. Embossing, forming, etc., of various PV, PE, PC and other thin-film switches and panels; 4. Pressing and forming various flexible circuit lines for laptop keyboards, etc. Small hydraulic presses use original Taiwanese or Japanese parts for the hydraulic power system, resulting in fewer malfunctions, high efficiency, low noise, low horsepower requirements, easy maintenance, and convenient adjustment of output, speed, and stroke.

Technology Daily (Reporter Shi Junbin, Correspondent Jiao Yue) Recently, a 19,500-ton free forging hydraulic press and a 300-ton/750-ton-meter full hydraulic forging manipulator, independently developed by China Heavy Industry Corporation, successfully completed their first hot load test run in Jiangyin, Jiangsu Province. This marks the completion of the world's largest tonnage free forging hydraulic press and the world's largest clamping force/clamping torque full hydraulic forging manipulator currently in operation, achieving a globally advanced level of overall equipment installation. The 19,500-ton free forging hydraulic press adopts a three-beam, four-column, three-cylinder, top-drive, press-insert, full pre-stressed frame structure. Both the upper and lower beams use pre-stressed composite beams. The maximum forging capacity can reach 4
