The invention relates to a preparation method for a fine grain anisotropy densified neodymium iron boron permanent magnet. The preparation method comprises the steps: traditional firing neodymium iron boron technology is adopted; a magnetic blank with small grains and loose texture is obtained by means of low-temperature presintering after rapid hardening, hydrogen breaking, air-stream milling and orientation forming; then the blank is hot-pressed and densified; and the anisotropy neodymium iron boron magnet with the small grains and densified is obtained after tempering is performed to the blank. According to the method, the grains in sintering process of magnet can be prevented from being larger effectively, the prepared magnet has a fine grain structure and is high in densification and the grain size of the fine grain anisotropy densified neodymium iron boron permanent magnet is close to air-stream milling powder granularity.

The invention relates to the technical field of packaging, and specifically discloses a packaging device for an electronic device. The packaging device comprises a feeding part, an adsorption part anda placement part, wherein the feeding part comprises a cylinder body, a first cylinder and an adsorption body, a gas cavity with an opening in the bottom is formed in the lower end of the cylinder body, the upper part of the adsorption body is inserted into the gas cavity, the first cylinder is installed in the cylinder body, the first cylinder is capable of driving the adsorption body to stretchout of or retreat back into the gas cavity, a gas hole communicating with the gas cavity is formed in the sidewall of the lower part of the adsorption body; the adsorption part comprises a dust removal pipe, a fan and an air pipe, an air channel is formed between the dust removal pipe and the air pipe, the middle part of the air pipe is sunken inwards, the upper part of the air channel communicates with the fan, and strip-shaped slits are formed in the sidewall of the dust removal pipe; sealing parts are arranged above and below the adsorption part separately, and each sealing part comprisestwo oppositely-arranged second cylinders and two oppositely-arranged hot-pressing blocks; and the placement part comprises a seat body and a workbench, the workbench is slidably connected to the seatbody, and a pressure spring is arranged below the workbench. The electronic device can be subjected to dust removal while being packaged, and the packaged bag body is enabled to be bulged.

The invention belongs to the technical field of marking equipment for packaging materials, and discloses a packaging bag forming and labeling integrated machine, which includes a workbench, on the workbench, an unwinding part, a hot-pressing part and a conveying part are sequentially arranged on the workbench, and the conveying part It includes two overlapping conveyor belts, the conveyor belts are driven by a motor, the worktable is provided with a placement slot, the bottom conveyor belt is located in the placement slot, and the upper surface of the bottom conveyor belt is coplanar with the upper surface of the worktable; The mounting frame on the table is vertically slidably connected with a plurality of heat-pressed blocks arranged side by side, and the adjacent heat-pressed blocks are fixed by connecting rods; The first cam that drives the push rod to move up and down; icons are set on the working surface of the hot pressing block. The invention solves the problem that an additional process needs to be added for label printing in the prior art, resulting in lower production efficiency of packaging bags.

The invention discloses a plane hot-pressing device for jackets. By driving a cylinder, a support horizontal plate drives a hot-pressing plate to move downward in the direction of a third sliding rail, hot-presses the cloth, drives a second motor, and a nut drives a connection The plate moves horizontally, and then drives the hot pressing mechanism to move, which can hot press the cloth in all directions, and will not cause uneven hot pressing because the cloth is too large. When in use, place the jacket fabric to be hot-pressed on the placement plate, fold the outer end of the fabric to the bottom end of the placement plate, turn the handle, and the threaded rod drives the clamping plate upward to clamp the fabric , it is convenient to hot-press it, and with the anti-skid protrusion, the clamping effect is better; at the same time, the present invention is designed with a first motor, which drives the first motor, and the first bevel gear and the second bevel gear rotate to drive the cloth on the placing plate. Rotation, when the cloth needs to be sorted, it is convenient to transfer the cloth to the side of the staff without manual movement, which is convenient for sorting the cloth.

The quenchable steel sheet has an alloy composition including carbon (C) in an amount of 0.15˜0.30 wt %, silicon (Si) in an amount of 0.05˜0.5 wt %, manganese (Mn) in an amount of 1.0˜2.0 wt %, boron (B) in an amount of 0.0005˜0.0040 wt %, sulfur (S) in an amount of 0.003 wt % or less, phosphorus (P) in an amount of 0.012 wt % or less, one or more selected from among calcium (Ca) in an amount of 0.0010˜0.0040 wt % and copper (Cu) in an amount of 0.05˜1.0 wt %, two or more selected from among cobalt (Co), zirconium (Zr) and antimony (Sb), and iron (Fe). Alloy elements are controlled to increasing hot ductility and enabling pressing at 600˜900° C. so that a tensile strength of 1400 MPa or more and an elongation of 8% or more are obtained after pressing.
