[0040] Reference Figures 1 to 7An energy-saving press cutting machine comprises: a frame 100; a clamping mechanism 200, which is arranged on the frame 100 and is used to clamp a workpiece to be cut; a cutting module 300, which comprises a sliding frame 310 and a cutting knife assembly 320, wherein the sliding frame 310 is provided with a plurality of sliding rods 311, and a slideway 110 corresponding to the sliding rods 311 is arranged on the frame 100, wherein the sliding rods 311 are slidably connected in the slideway 110, and a sealing slip ring 312 is sleeved on the sliding rod 311, and a plurality of exhaust holes 111 are opened on the side wall of the slideway 110, and the plurality of exhaust holes 111 are arranged along the slideway 110. The axially spaced distribution, several exhaust holes 111 are connected to a pump 114, a support plate 112 is slidably arranged in the slide 110, and the support plate 112 is connected to the bottom of the slide 110 through an elastic member 113; the cutting knife assembly 320 is detachably connected to the sliding frame 310, and the cutting knife assembly 320 is arranged above the clamping mechanism 200, and the sliding frame 310 is used to drive the cutting knife assembly 320 to press and cut the workpiece to be cut on the clamping mechanism 200; the limit block 500 is slidably connected to the frame 100 along the vertical direction, and the limit block 500 is used to block the cutting module 300. The slide bar 311 is slidably connected in the slideway 110. Under the action of the pump 114, the pumping fluid drives the slide bar 311 to rise and fall, thereby making the cutting blade assembly 320 rise and fall to complete the pressing and cutting function. In the process of the cutting blade assembly 320 descending, the weight of the cutting blade assembly 320 is used as the main power source, and the gravitational potential energy of the cutting blade assembly 320 is fully utilized to reduce the additional force applied by the pump 114, so that the cutting blade assembly 320 can be pressed downward steadily for the function to be cut, avoiding the large friction with the limit block 500. Large rigid impact, and under the limiting effect of the exhaust hole 111 and the elastic member 113, the gravity of the cutting knife assembly 320 is reduced to be completely borne by the workpiece to be cut, so as to avoid the workpiece to be cut from being subjected to huge impact. After the clamping mechanism is clamped, the workpiece to be cut is cut into blocks of a predetermined size by the lifting movement of the cutting module. The structure is simple and the stroke is fast, which can meet the cutting requirements of the workpiece to be cut. The limit block is adjusted along the vertical sliding, which is convenient for setting the cutting depth and pressing the workpiece according to the needs.It can be understood that the elastic member 113 includes a coil spring or a spring sheet or an elastic block, etc. The diameter of the exhaust hole 111 is much smaller than the diameter of the slideway 110. During the sliding of the slide bar 311, the slide bar 311 is to exhaust the gas in the slideway 110. Since the diameter of the exhaust hole 111 is small, the exhaust volume is also small, and the excess gas or fluid will hinder the sliding of the slide bar 311. As the slide bar 311 continues to slide, the slide bar 311 will cover some exhaust holes 111 along the axial direction, resulting in a decrease in the number of exhaust holes 111, and further using air pressure to hinder the sliding of the slide bar 311, so the exhaust hole 111 is provided along the axial direction. The exhaust holes 111 can gradually increase the resistance during the sliding of the slide bar 311, further reducing the rigid collision force between the slide bar 311 and the limit block. During this process, the sliding of the slide bar 311 has a hysteresis. This hysteresis can be used to prevent the workpiece from being completely cut off when it is pressed and cut. The workpiece can be installed and taken out as a whole, and when it is to be divided into small pieces, it only needs to be broken apart along the incision. At the same time, the pump 114 can also apply additional suction to suck the slide bar 311 to slide as compensation for the pressing and cutting force. Of course, this is a strategy that needs to be adopted when facing different workpieces.

The first cutting knife 321 or the second cutting knife 322 can be slidably set in the corresponding opening 324, and the first cutting knife 321 and the second cutting knife 322 are criss-crossed. It should be noted that both the first cutting knife 321 and the second cutting knife 322 are electrically heated, and the contact point between the first cutting knife 321 and the second cutting knife 322 is insulated, for example, sprayed with an insulating ceramic layer, etc., and the plurality of first cutting knives 321 and the plurality of second cutting knives 322 are arranged in this movable manner to form different grid combinations, thereby realizing different pressing and cutting methods for the workpiece, and having a wide range of adaptability.
