6results about How to "Save punching time" patented technology

The invention relates to the field of punching facilities, in particular to a bidirectional full-automatic workpiece punching machine which comprises a machine table and a clamping mechanism installed on the front portion of the upper end of the machine table, a lifting piece is installed on the rear portion of the upper end of the machine table, a pressing piece is installed at the front end of the lifting piece, and a first driving motor is connected to the end of the pressing piece; a first driving motor is connected to the upper end of the machine table, a first drill bit is coaxially and fixedly installed at the output end of the first driving motor, a pushing piece is installed on the front portion of the upper end of the machine table and located on the side of the clamping mechanism, a second driving motor is connected to the upper end of the pushing piece, and a second drill bit is coaxially and fixedly installed at the output end of the second driving motor. According to the bidirectional punching device, bidirectional punching can be conducted on a workpiece at the same time, the punching time is effectively shortened, the punching efficiency is improved, meanwhile, collision between the first drill bit and the second drill bit in the punching process is avoided, and normal downward movement of the lifting base is guaranteed.

The utility model provides a kind of human resource management archives auxiliary threading device, it is related to the technical field of archives management, including base, left stand plate, first sliding slot, first bearing, first lifting plate, screw rod, hand wheel, upper antiskid block, lower antiskid block, arc hole and punch assembly etc.;Traditional manual binding needs page by page alignment, manual punching, for the archives of greater thickness, it is cumbersome and time-consuming to operate.And the device realizes automatic punching through punch assembly, multiple drill bits can work simultaneously, and punching operation of multiple hole positions is completed at one time, which greatly reduces the punching time and significantly improves the overall efficiency of archives binding.Operators do not need to repeat punching, threading and other mechanical actions, effectively reducing hand fatigue caused by long-term operation, reducing the work failure rate and reducing labor intensity.

The utility model relates to the technical field of outer wall formwork installation, in particular to a trepanning-free basement outer wall formwork and finished product steel abutted seam strip assembling structure which comprises a floor and a plurality of fixing steel strips, the fixing steel strips are fixedly installed on the upper surface of the floor, a plurality of baffles are arranged above the floor, and the baffles are fixedly installed on the upper surface of the floor. A steel splicing strip is clamped between every two baffles, a steel cross-shaped block is clamped between every two steel splicing strips, columnar grooves are formed in one side of each steel cross-shaped block and one side of each steel splicing strip, a transverse supporting device is arranged on one side of each columnar groove, and a transverse supporting device is arranged on one side of each transverse supporting device. Side plates are arranged on one sides of the baffles on the left side and the right side; the outer wall formwork has the beneficial effects that in the installation process of the outer wall formwork, holes do not need to be punched in the steel joint strips and the baffles, operation is more convenient, and the punching time is saved.

The invention relates to an incremental launching construction method for a box culvert overcrossing a subway. The incremental launching construction method comprises the following steps that S101, a supporting system is constructed, specifically, the supporting system is constructed in front of the box culvert and above an existing subway; in the pushing direction, a sliding plate is arranged at the bottom end of the initial position of the box culvert, and the box culvert slides on the sliding plate; the soil body in front of the box culvert and above the existing subway is subjected to multiple times of grouting reinforcement; and S103, box culvert pushing construction is conducted, specifically, a counterweight assembly is installed at the top end of the box culvert, and the installation position of the counterweight assembly on the box culvert is adjusted along with pushing of the box culvert. According to the incremental launching construction method, the jacking direction of the box culvert can be limited through the high-pressure jet grouting piles and the supporting piles, and the box culvert is prevented from deviating in the incremental launching process; and deep hole grouting reinforcement is carried out on soil bodies at the bottom ends of the multiple high-pressure jet grouting piles and the multiple supporting piles, and dense grouting reinforcement is carried out on weak stress positions of the soil bodies, so that the high-pressure jet grouting piles, the supporting piles and a grouting reinforcement area form a U-shaped structure reinforcement system.

The utility model discloses a circuit board punching machining structure which comprises a base table, an L-shaped column and a hydraulic cylinder installed on the L-shaped column, an installation base is fixedly arranged at the working end of the hydraulic cylinder, a punching mechanism is arranged at the working end of the hydraulic cylinder, the punching mechanism comprises four sets of punching needle bodies, two sets of transverse moving pieces and two sets of moving pieces, the punching needle body is fixed to the bottom of the moving part, the transverse moving part is located between the moving part and the mounting base, the moving part comprises a concentric-square-shaped plate, two sets of vertical screw rods are arranged in the concentric-square-shaped plate, and the top of the punching needle body is fixedly connected with the bottoms of the vertical screw rods; according to the circuit board punching machine, through the designed punching mechanism, four groups of punching needle bodies can be used for punching the corners of the periphery of a batch of circuit boards at the same time in the using process, so that holes in the circuit boards can be punched at a time, the punching time is saved, the punching efficiency of the circuit boards is improved, and the fatigue degree of operators is reduced.
