Construction steel bar punching and shearing machine

Abstract

The invention discloses a construction steel bar punching and shearing machine, and belongs to the field of construction material machining mechanical equipment. According to the construction steel bar punching and shearing machine, a reinforcing steel bar feeding mechanism and a reinforcing steel bar shearing mechanism are sequentially arranged on a reinforcing steel bar machining support in the horizontal direction, the output end of a translation push-pull air cylinder is fixedly connected to one side of a reciprocating translation guide plate, a reinforcing steel bar feeding support is vertically and fixedly arranged on one side of the reciprocating translation guide plate, a reinforcing steel bar feeding pressing wheel is vertically arranged above a reinforcing steel bar bearing guide wheel, the lower side of an upper shearing pressing plate is closely adjacent to the upper side of a lower shearing bearing plate, a reciprocating moving plate is slidably arranged on a lifting reciprocating guide rod in the vertical direction, the middle of the reciprocating rotating connecting plate is hinged to a translation adjusting guide plate, and the upper end of the reciprocating rotating connecting plate is connected to a translation push plate rod through a pull rod connecting lead screw. According to the construction steel bar punching and shearing machine, the structural design is reasonable, construction steel bars can be continuously punched and cut into sections efficiently and stably, the cutting length of the construction steel bars can be conveniently and accurately adjusted according to actual use requirements, and the machining and using requirements are met.

Description

technical field [0001] The invention belongs to the field of building material processing machinery and equipment, and in particular relates to a punching and shearing machine for building steel bars. Background technique [0002] Building steel bar refers to the steel used for reinforced concrete and prestressed reinforced concrete. The cross section of building steel bar is generally circular, and there are also square cross sections with rounded corners, including smooth round steel bar, ribbed steel bar and twisted steel bar. It is used for reinforced concrete Steel bar refers to the straight or coiled steel used for reinforced concrete reinforcement. Its shape is divided into two types: smooth round steel bar and deformed steel bar. In terms of function, building reinforcement can be divided into compression reinforcement, tension reinforcement, erection reinforcement, distribution reinforcement and angle reinforcement. During the processing of building steel bars, the...

Problems solved by technology

When making corner bars and stirrups, the longitudinal reinforcement on the four corners of the rectangular column is the corner reinforcement, and the transverse reinforcement that hoops the longitudinal reinforcement of the column is the stirrup. Column reinforcement skeleton cage, the length of the stirrup is relatively short, in the actual processing process, mainly use the longer length of the steel bar to punch and cut into multiple shorter length of the stirrup according to the needs, the existing steel punching and shearing machine structure Complicated and cumbersome to operate, in the process of punching and shearing building steel bars, it is difficult to efficiently and smoothly process building steel bars in a continuous punching and shearing process, and it is difficult to ensure that the length of building steel bars processed by continuous punching and shearing is accurate and uniform. In the process of processing, not only the automatic and accurate measurement of the punching and shearing length of building steel bars cannot be realized, but also it is difficult to conveniently and accurately adjust the punching and shearing length of building steel bars according to the actual use of building steel bars. During the punching and shearing process of steel bars, the scale is used to calibrate and measure the length of building steel bars manually. The operation of measuring the length of building steel bars is troublesome and the error rate of length measurement is large. It is difficult to ensure that the continuous punching and shearing length of building steel bars is accurate, controllable and uniform, which affects the efficiency and The quality cannot meet the needs of construction processing
