The invention provides a U-folding and feeding mechanism for a rectangular enameled wire and belongs to the field of bending equipment. A turning driving mechanism is in transmission connection with a turning part by a transmission mechanism; a wire intake channel in the horizontal direction is arranged on the turning part, and a U-folding operation space is formed on the wire intake channel; a U-folding cylinder is connected with a U-folding head, a U-folding forming die is located below the U-folding head, and a U-folding channel adapting to the U-folding head is arranged on the U-folding forming die; a wire feeding cylinder is in transmission connection with a wire feeding tongue; a guiding chute vertically penetrating the U-folding head is arranged, the lower section of the wire feeding tongue is located in the guiding chute, and the upper section of the wire feeding tongue is exposed out of the guiding chute; the U-folding cylinder is mounted on a base and drives the wire feeding cylinder to move up and down; the U-folding forming die is mounted on the base; the wire intake channel is located above the U-folding forming die; the U-folding operation space is located right above the U-folding channel. The U-folding and feeding mechanism for the rectangular enameled wire improves the coherence of all procedures, saves time spent in the whole working process from input of the enameled wire to collection of the enameled wire, and facilitates follow-up operation.

A shoelace buckle automatic threading machine and application thereof are disclosed. The shoelace buckle automatic threading machine comprises a machine base, and a buckle head feeding device and a leather strip rotating wheel are arranged on the machine base and used for feeding metal buckle heads and leather strips respectively; an intermittent linear reciprocating mechanism is arranged on the machine base in the horizontal direction, and a head buckling mechanical arm is arranged on a sliding base of the intermittent linear reciprocating mechanism. A supporting base is arranged on the machine base and located behind the intermittent linear reciprocating mechanism, a first air cylinder and a horizontally-arranged first sliding way are arranged on the supporting base, and the first air cylinder is connected with a traction base arranged on the first sliding way. A traction feeding mechanism and a cutting and tapping mechanism which are arranged up and down are arranged on the tractionseat; an automatic two-axis displacement table is arranged on the supporting base in the longitudinal direction, and a strap mechanical arm is arranged on an X-axis platform of the automatic two-axisdisplacement table. A buckle head clamping mechanism is arranged on the supporting base in the transverse direction. The upper end of the supporting base is provided with a buckle penetrating mechanical arm in the longitudinal direction. The machine is high in production efficiency, capable of effectively reducing the labor intensity of workers, good in product consistency and beneficial to subsequent operation.

The invention discloses a buckle penetrating machine with an automatic feeding function. The buckle penetrating machine comprises a machine seat provided with a buckle feeding device, a cloth strip runner and an intermittent linear reciprocation mechanism. A manipulator is arranged on a sliding seat of the intermittent linear reciprocation mechanism. A traction seat is arranged on the sliding seatand is located above the manipulator. An oblique cloth strip penetrating hole is formed in the lower end of the traction seat. The traction seat is provided with a swing strip pulling mechanism. Thetraction seat is inserted in the sliding seat through a vertically arranged guide column and a reset spring. The traction seat is in linkage with the driving end of the intermittent linear reciprocation mechanism. An electric heating blade capable of reciprocating in the transverse direction is installed in a notch in the lower portion of the traction seat and is used for cutting off a cloth strippenetrating into a buckle and for bonding two cut-off ends. Through the buckle penetrating machine, a whole set of procedures such as automatic feeding, fetching, penetrating, cutting-off and bondingof the buckle and the cloth strip can be achieved, production efficiency is high, labor intensity of workers can be lowered effectively, product consistency is good, and subsequent operation is facilitated.

The collecting agent for floatation of copper sulfide ore is prepared by using thionocarbamate, diethylthionitrogen ester, 730A, dialkyl phosphorodithioate and propenyl butyl sulfonate according to the ratio of 0.6-0:0-0.06:0.2-0.1:0.1: 0.1-0.2, and its preparation method includes the following steps: respectively filtering thionocarbamate and 730A; under the condition of normal temp. and normal pressure slowly adding diethylthionitrogen ester while stirring, uniformly stirring them, then adding it and propenyl butyl sulfonate into dialkyl phosphorodithioate, stirring for 1 hr. then standing still for 2 hr. and removing precipitate so as to obtain the invented collecting agent with good selectivity and strong collecting power, and it can effectively separate copper-sulfur, copper-in and copper-arsenic, etc.

The invention relates to a well cementing pipe string and a well cementing method. The cementing string includes a bumper seat and at least one positioning mechanism arranged at a predetermined position upstream of the bumper seat, and when the cementing plug reaches the predetermined position, the positioning mechanism responds to the cementing The arrival of the rubber plug sends out a positioning signal. The downhole position where the cement slurry arrives can be determined more accurately through the cementing string.
