A full-automatic in-line hydraulic bevel shearing machine for bevel shearing of hot steel billet on conticasting production line is composed of base, machine frame arranged obliquely on the base and consisting of left and right frames and upper and lower beams, guide tracks on left and right frames, shearing unit consisting of upper and lower V-shaped shearing knives and their holders, press unit consisting of cylinder and its supporter, pressing head and guide rod, and walking unit on said base.

The invention discloses an eyelet embroiderer. The eyelet embroiderer comprises a cutter bar. The bottom of the cutter bar is provided with a cutter head. The top end of the cutter head is provided with a cutting edge part. The cutter bar above the cutter head is provided with upper and lower driving mechanisms. The cutter bar above the upper and lower driving mechanisms is provided with a rotation driving mechanism. The cross section of the cutting edge part is rhombic. An angle of the cutting edge part in a width direction is in a range of 20-90 degrees and an angle of the cutting edge part in a thickness direction is in a range of 5-20 degrees. The eyelet embroiderer is provided with the rotation driving mechanism except the upper and lower driving mechanisms and thus the cutter bar drives the cutter head to punch upward and downward and to carry out rotation cutting. The angle of the cutting edge part in the thickness direction is in a range of 5-20 degrees so that cutting-off efficiency is improved and the angle of the cutting edge part in the width direction is in a range of 20-90 degrees so that eyelet width is adjusted easily and cutting-off efficiency is improved. The eyelet embroiderer improves a cutting-off rate, guarantees cut surface cleanliness and obviously improves punching efficiency and punching quality.

The invention belongs to the technical field of fruit and vegetable picking, and discloses a near-ground fruit and vegetable picking machine. The near-ground fruit and vegetable picking machine comprises a picking execution module, a picking drive module and a picking control module; the picking execution module comprises an upper guiding cam cover and a lower guiding cam base, the upper guiding cam cover is internally provided with an upper cam groove, and the lower guiding cam base is internally provided with a lower cam groove; the upper guiding cam cover and the lower guiding cam base cooperate to form a hollow containing cavity, the hollow containing cavity is internally provided with a cutter head, an upper rotary cutting blade and a lower rotary cutting blade, and the cutter head can be driven by the picking drive module to drive the upper rotary cutting blade and the lower rotary cutting blade to conduct circular movement separately; the picking control module controls the picking drive module to move to make the cutter head conduct circular movement; the upper rotary cutting blade and the lower rotary cutting blade can move in the upper cam groove and the lower cam grooverespectively; the upper and lower rotary cutting blades rotate along with the cutter head to complete the operation of cutting the picking parts and are also controlled by a cam curve to swing to complete the cutter combination cutting and cutter removing operation of the upper and lower rotary cutting blades.

The invention discloses a spinning type manually-operated hydraulic steel bar cutting-off device capable of working in two directions. The device comprises a knife seat and a control cabinet. Stationary knives are mounted on the knife seat. A movable knife is mounted beside each stationary knife. The control cabinet is arranged beside the knife seat. Hydraulic rods are arranged at the front end of the control cabinet. Oil drain valves are arranged above the control cabinet. A hand wheel is arranged beside the oil drain valves. A reversing rod is arranged on the side face of the control cabinet. A linkage rod is arranged beside the reversing rod. The spinning type manually-operated hydraulic steel bar cutting-off device has the beneficial effects that the two-directional cutting-off knives can be used separately or together; the application scope is wide; and in addition, steel bar cutting-off speed can be increased.

The invention relates to cutting-off equipment, in particular to wire hardness cutting-off equipment for instrument production. According to the technical aims, the wire hardness cutting-off equipmentfor instrument production is high in cutting-off speed and uniform in cutting-off. The wire hardness cutting-off equipment for instrument production comprises a tank, supporting legs, supporting boards, arc-shaped boards, a first transverse board, a first vertical board, a first bearing pedestal, a first rotary shaft, a first roller, a first belt wheel and the like. The supporting legs are installed at four corners of the bottom of the tank; a feeding inlet is formed in the middle of the top of the tank; a discharging outlet is formed in the middle of the bottom of the tank; the two supporting boards are installed on the top of the exterior of the tank; and the feeding inlet is located between the two supporting boards. A first motor is used as a driver to drive the first roller to rotate, so that wire harnesses are driven to move downwards; and a cam drives a cutter to cut off the wire harnesses, a movable plate and a fourth spring are also arranged, so that the cut-off wire harnesses are not stacked, and the effects that the wire harnesses are cut off fast and uniformly are achieved accordingly.
