Provided is a method for directly carrying out innocent treatment on electrolytic manganese residues in filter pressing plate frames. The electrolytic manganese residues treated through the method are filter cakes obtained after filter pressing in the filter pressing plate frames of a plate-and-frame filter press, and sodium dihydrogen phosphate, calcium oxide, magnesium oxide and polyacrylamide are included in a treating agent. The method comprises the steps that 1, the electrolytic manganese residue filter cakes in all the filter pressing plate frames are washed through solutions obtained by mixing the sodium dihydrogen phosphate and water; 2, after the magnesium oxide, the calcium oxide and the polyacrylamide are dissolved in filter liquor collected in the step 1, the electrolytic manganese residue filter cakes are washed again; 3, filter liquor generated in the step 2 is collected, the plate-and-frame filter press is loosened to unload the filter cakes, and the electrolytic manganese residues generated after the innocent treatment are obtained. According to the method, soluble manganese in the electrolytic manganese residues is fixed, meanwhile, soluble ammonia nitrogen in the electrolytic manganese residues is fixed, and compared with the prior art, the advantages in the prior art are kept, the defects in the prior art are overcome, and the total cost of innocent treatment on the electrolytic manganese residues is lowered.

The method includes steps of pattern making, materialpreparation, zippering, middle seam making, zipper turning and stitching. By the upper garment top fly manufacturing method, staggering of two front pieces due to zipper mounting staggering can be avoided. The whole process is simple, convenient and high in accuracy, the process difficulty is sharply lowered, and demands of upper garments in different styles can be met.

The invention discloses a linear feeding and discharging mechanism of a full-automatic bar chamfering machine. The linear feeding and discharging mechanism of the full-automatic bar chamfering machine comprises a work head mechanism, a feeding mechanism and a receiving mechanism. The work head mechanism comprises a clamping head used for clamping bars and a spindle used for driving the clamping head to rotate. A hollow inner cavity is formed in the spindle, and the bars at the front end of the spindle can be conveyed out toward the rear end of the spindle along the hollow inner cavity. The feeding mechanism comprises a linear feeding precision linear module which can make linear reciprocating movement, and the linear feeding precision linear module is arranged at the position where linear reciprocating movement can be made in the axis direction of the spindle of the work head mechanism to enable the bars of the work head mechanism to be pushed in the hollow inner cavity of the spindle along a straight line. The receiving mechanism is arranged to enable the bars discharged by the hollow inner cavity of the work head mechanism to be conveyed to a receiving position in a linear mode. According to the linear feeding and discharging mechanism, the feeding mode is changed into a front positioning mode from a rear positioning mode, the feeding mode of front feeding and front discharging is changed into a work head inside linear discharging mode, so that the entire structure of the mechanism is compact, and the production efficiency and the product percent of pass are improved while the requirement for precision can be met.

The invention discloses a convenient-to-operate common conveying device for vehicle doors and trunk lids, which is sued for solving the problems that the conveying device is inconvenient to manually operate and that one conveying device corresponds to only one kind of work pieces. The technical scheme is that: the common conveying device comprises an underframe and support frames fixed on the underframe; conveyor belts and material blocking plates are arranged on the support frames; after the conveying device is improved, lifting cylinders are arranged on the underframe; lifting cylinder rodsare fixedly connected with the support frames; the conveyor belts comprise fixed conveyor belts and lifting conveyor belts; conveyor belt lifting cylinders are arranged at the support frames; and conveyor belt lifting cylinder rods are fixedly connected with the lifting conveyor belts. The common conveying device can reduce operation heights for workers to take and put the work pieces, greatly reduce the labor intensity of the workers, realize the applicability of one conveying device to the conveyance of the two kinds of work pieces, namely, the vehicle doors and the trunk lids, simultaneously save the occupation of a production site and reduce the tool cost, is favorable for improving the production efficiency and overcomes the shortcomings of waste of working hours and low production efficiency caused by the frequent replacement of the conveying devices.

The invention relates to a PLC-based automatic timing system and a timing method thereof, which are used for automatic calculation of the workload of workers in a metal product factory per shift. The system includes the motor and AC contactor at one end of the finished product line, the PLC controller and the upper computer. The switching signal of the AC contactor is collected through the PLC controller, the running time of the motor is calculated, and the data is transmitted to the upper computer through the industrial Ethernet network. The upper computer Calculate the output of each wire drawing machine and nail making machine according to the running time of the motor, and directly generate a report for the settlement of the worker's workload. At the same time, the upper computer sends a clear command to the PLC master station. After the PLC master station clears all the data on duty , the system starts a new round of timing. This automatic timing system avoids the waste of working hours caused by workers weighing the finished product and calculating the workload before leaving get off work every day. It not only saves the purchase and maintenance costs of weighing equipment, but also speeds up the production rhythm and improves production efficiency.
