The invention discloses a reinforcing steel bar cutting device with clamping functional stability. The reinforcing steel bar cutting device comprises a base, wherein a box body is fixedly arranged on the top of the base; a controller is fixedly arranged on the front surface of the base; damping sizing blocks are symmetrically arranged at the bottom of the base; supporting legs are fixedly arranged at the bottom of the damping sizing blocks; fixed rods are fixedly arranged among the damping sizing blocks; a through groove is formed in the top of the box body; and a U-shaped plate is fixedly arranged at the bottom of the inner wall of the box body. According to the reinforcing steel bar cutting device with the clamping functional stability, through the arrangement of a fixing device, a first automatic telescopic rod and a second automatic telescopic rod, a reinforcing steel bar placed on the box body can be well fixed by the L-shaped plate, so that the stability of the reinforcing steel bar in the cutting process is improved, the movement of the reinforcing steel bar in the cutting process of the reinforcing steel bar is avoided, the cutting precision of the reinforcing steel bar is improved, the damage of a cutting knife is further avoided, and the cutting safety is improved.

The invention discloses a cutting device for crystal, which comprises a machine body. A cutting cavity with an inclined lower end wall is arranged in the body. A front and back symmetrical clamping device is arranged in the cutting cavity, and the clamping devices face each other. The movement is used to clamp the crystal raw material. A discharge groove is connected between the lower side of the cutting chamber and the outside world. The invention has a simple structure and is easy to operate. The rotation of the cutter can drive the movement of the crystal raw material, so that the raw material can be cut easily. During the movement and the rotation of the cutter, a quantitative amount of coolant is added to the cutting part to reduce the cutting temperature. This device is fully automated during the cutting process, and the cutting safety is high.

The invention discloses a protection film breaking mechanism for an aluminum material film pasting machine. The protection film breaking mechanism comprises a cutter holder and a cutter. The aluminum material film pasting machine comprises a left horizontally-moving plate and a right horizontally-moving plate, wherein the left horizontally-moving plate and the right horizontally-moving plate can horizontally get close to or be away from each other. The cutter holder comprises a left slide base and a right slide base, wherein the left slide base and the right slide base can slide relative to the left horizontally-moving plate and the right horizontally-moving plate correspondingly. A slide block is arranged on the left slide base. A guide column extending towards the left slide base is arranged on the right slide base. The slide block is sleeved with the guide column in a connected manner. A cutter installation platform is arranged on the right slide base. A movement assembly is arranged on the cutter installation platform and is used for driving the cutter installation platform and aluminum materials to synchronously move. The cutter installed on the cutter installation platform and the aluminum materials can synchronously move. In the cutting process, the cutter is kept aligned with the gap between the front aluminum material and the aluminum material behind all the time. The cutting efficiency is improved, and the cutting safety is also improved.

The invention relates to the technical field of cutting devices of cherry tomatoes, in particular to a variable-cavity cherry tomato slicing device. The slicing device comprises a bottom disk, a disk cover and a cutter, wherein the bottom disk is used for accommodating the cherry tomatoes, and is provided with a concave part; the disk cover is used for pressing the cherry tomatoes, and is provided with a concave part; the cutter is used for cutting the cherry tomatoes; a lower connecting part extends from one side of the bottom disk; an upper connecting part which corresponds to the lower connecting part extends from one side, which corresponds to the lower connecting part, of the disk cover; the lower connecting part is hinged to the upper connecting part; a spring is further arranged between the lower connecting part and the upper connecting part; an accommodating space for accommodating the cherry tomatoes is formed between the bottom disk and the disk cover; a gap between one side, which is far away from the lower connecting part, of the bottom disk and one side, which is far away from the upper connecting part, of the disk cover is greater than the thickness of the cutter. The variable-cavity cherry tomato slicing device has the advantages of high cutting safety, high efficiency, good pressing effect, and easiness and convenience in operation.

The present invention provides a laser cutting tool and a laser cutting production line for soft-pack battery tabs. The laser cutting production line includes the laser cutting tool, and the laser cutting tool includes: a first fixing seat, a second fixing seat, an upper pressing assembly and a lower pressing assembly ;The lower pressing assembly includes a first driving mechanism, a movable seat, an overturning driving mechanism and a movable pressing block, and the movable pressing block is provided with chip blanking holes and air holes; Cut path holes. After the pouch battery arrives at the station, the first driving mechanism drives the movable pressing block to move up to touch the tab, and the second driving mechanism drives the upper pressing structure to move down. After the tab is clamped together, the tab can be cut. The chip drop hole falls, and the tab waste is absorbed by the air hole. After the battery is moved out of the station, the movable pressing block is turned to the vertical position, and the suction hole blows air to make the tab waste fall. The laser cutting tool of the present invention can adapt to the diverse requirements of tab cutting and has high safety.

The invention relates to the field of waste and old fiber grade polypropylene recycling devices, in particular to a fiber grade polypropylene pipe cutting method, the used polypropylene pipe cutting and lifting device includes universal wheels, gantry, limit structure, height adjustment Structure and angle adjustment structure; when the height adjustment structure interferes with the angle adjustment structure, it is convenient to drive the limit structure to reset, which makes the limit structure reset more convenient. At the same time, the limit structure releases the pressure on the height adjustment structure through air pressure, effectively preventing height adjustment The structure impacts the angle adjustment structure. When the height adjustment structure is used, the angle adjustment structure drives the waste winding pipe on the limit structure to rotate, which facilitates the ring cutting of the pipe, reduces the occupied space, and improves the cutting of large pipes. Efficiency and its quality make cutting more secure.

The present invention relates to a device 7 for cutting track-like material 1 as well as a method for producing transverse cuts 6 in a track-like material 1 in a continuous operating process. To increase the service life of the device 7 and to improve the cut reliability, it is proposed that the counter-tool 10 to the cutting tool 8 form, in the active position (cutting position), a blunt counter-surface 12 for the cutting tool 8, which counter-surface is in direct contact with the track-like material 1 and is not cuttable.
