An insert-exchangeable, rotary tool to which throwaway inserts are detachably attached, the insert comprising substantially square-shaped face and bottom surface and an outward curved flank on each side surface, and having a positive-type shape in which an outward curved edge line formed by the face and the flank serves as a cutting edge; each flank having in a substantially center portion a flat surface portion extending to the bottom surface without contacting with the cutting edge; a major cutting edge formed by the outward curved edge line circularly extending from its lowermost point toward a periphery of the tool when the insert is attached to the insert-exchangeable, rotary tool, such that it has a negative radial rake; and the lowermost point being positioned inward a center of the outward curved major cutting edge.

The invention relates to a feeding device of a shearing machine. The feeding device comprises a clamping mechanism for clamping a bar and a feeding mechanism for feeding the bar to a shearing system of the shearing machine. The feeding mechanism comprises a support and a feeding cylinder for driving the clamping mechanism to move back and forth. The feeding cylinder is connected to the support. The feeding device further comprises a guiding bearing bar. The clamping mechanism is erected on the guiding bearing bar in the mode of sliding relative to the guiding bearing bar. The clamping mechanism is improved, stable clamping is ensured, and meanwhile an adjusting device is added, so that bar conveying abrasion is avoided. The feeding device has the advantages of being simple in structure and capable of improving the product quality and prolonging the service life of a machine table.

A break pattern of a silicon wafer includes a line to be cut which is set in the silicon wafer assuming a surface as a (110) face in a surface direction of a first (111) face perpendicular to the (110) face; and through holes which are provided in a plurality of rows on the line to be cut, wherein each of the through holes has a first (111) face, a second (111) face which intersects the first (111) face, and a third (111) face which intersects the second (111) face and the first (111) face, an intersecting point with end edges of the second (111) face and the third (111) face is assumed as a point closest to the adjacent through holes.

The invention provides a broken-ring eight-treasure porridge zip-top can opening device opened according to the lever principle and a using method, and relates to the field of daily necessities. The broken-ring eight-treasure porridge zip-top can opening device opened according to the lever principle comprises an outer cover fixing cylinder, a protruding pressing block is arranged on the side portion of the outer cover fixing cylinder, a mounting bearing is bonded to the top of the outer cover fixing cylinder, an autorotation fixing rod is bonded to the inner wall of the mounting bearing, and a prying handle is arranged in the mounting bearing and located on the side portion of the autorotation fixing rod. According to the broken-ring eight-treasure porridge zip-top can opening device opened according to the lever principle, when a top cover is cut, the prying handle is pressed downwards to be parallel to the can top, a cutting arc piece can be controlled to open the can top, when a zip-top can similar to carbonated beverage is opened, the cutting arc piece is positioned at a drinking opening, the end, away from the cutting arc piece, of the prying handle is lifted, the zip-top can can be easily opened according to the lever principle, simplicity and convenience are achieved, and accidents that the zip-top can slips and is scratched when people hold the zip-top can and prize the zip-top can through sharp objects are avoided.

The invention relates to the technical field of metal processing, and discloses an aluminum material cutting machine that protects the motor from cutting material stably. , the top of the foot column is fixedly connected with a chain group, and two transmission gears are meshed at both ends of the chain group, and a telescopic gear is meshed between the two transmission gears inside the chain group, and the telescopic gear wheel Teeth are slidably connected to the tops of the teeth, and the front of the bottom plate is fixedly connected with a range-adjusting rod group, and the end of the distance-adjusting rod group is fixedly connected with a rocker. The aluminum material cutting machine that protects the motor and cuts materials stably, drives the transmission gear to rotate through the motor, and the transmission gear drives the telescopic gear to rotate through the chain, and then drives the cutting knife to rotate and cut aluminum materials, so that through the transmission of the chain, the cutting knife generated when working The vibration is buffered to the minimum, which reduces the vibration of the motor and prolongs the service life of the motor.

This patent discloses a processing method of broad beans, the steps are as follows: (1) preparation: use a cutting device for broad beans; (2) selection: pick out broad beans with uniform particles; (3) soak beans: soak broad beans in clear water (4) drying: drying the soaked broad beans; (5) adding edible oil: adding edible oil into the frying box; (6) putting into the processing box: putting the dried broad beans into the processing box, and the broad beans are Guided by the side wall of the processing box, it moves to the through hole of the soft layer; (7) Cutting: start the rotating motor to drive the cam to rotate, the cam squeezes the extrusion plate intermittently and drives the extrusion column to move vertically under the action of the pressure spring. Do reciprocating motion in the direction, the cutter not only completes the cutting of the broad beans, but also squeezes the broad beans from the through hole and falls into the frying box; (8) Frying: start the heater, use the heater to heat the food in the frying box Oil fried broad beans. This solution mainly solves the problems of low efficiency and easy cutting of hands in the traditional broad bean cutting process.
