Problems solved by technology

There are mainly two types of steel bar cutting equipment currently used in China: one is a cutting machine, the working principle is that the motor drives the V-belt, and the V-belt drives the second gear to drive the crankshaft to rotate after deceleration, and the crankshaft pushes the connecting rod to make the slider and the moving blade in the same position. Reciprocating linear motion is made in the slideway of the machine base, so that the movable blade and the fixed blade are staggered to cut the steel bar. Since the steel bar is squeezed and broken by the blade, most of the section of the cut steel bar is squeezed and deformed, and the section is mostly horseshoe-shaped. Before threading, it is necessary to grind with an angle grinder or cut with a grinding wheel cutting machine to ensure that the end face is perpendicular to the axis; the other is a grinding wheel cutting machine. Rebar blanking is currently the equipment that can best meet the quality requirements of steel bar straight thread sleeves on the steel bar end face, but the efficiency is low, and the grinding wheel is easy to wear and needs to be replaced frequently. When the noise is large and accompanied by sparks to pollute the environment, it is easy to cause fire accidents, and the social and economic benefits are poor
Since threaded steel bars need to be hoisted in a centralized manner, the straight thread processing of steel bars must be carried out within the coverage of hoisting machinery such as tower cranes. To prevent objects from hitting, it is necessary to set up a protective shed. Due to the particularity of the threaded steel bar, during the hoisting process , the steel bars are easy to collide with the protective shed, causing damage to the workshop or even personal injury. The construction of the protective shed has become a difficult point in construction technology
[0004] Since the processing technology of the straight thread threading operation of the steel bar requires that the end of the steel bar be cut flat before the threading can be carried out, due to the need for centralized lifting of the threaded steel bar, the above work must be carried out within the coverage of lifting equipment such as tower cranes. Due to the particularity of the wire operation, during the hoisting process of the threaded steel bars, the steel bars are easy to collide with the workshop, causing damage to the workshop and even personal injury
The construction of protective sheds has become a difficult point in construction technology. Due to unreasonable safety protection for threading operators, accidents caused by objects hitting occasionally occur. In addition, since the cutting and threading of steel bars need to be completed independently by threading machines and steel cutting equipment, the processing sites are scattered and the work is difficult. Due to the division of labor, there is often the phenomenon of threading waiting for the head to be cut or the threading has not been done in time after the head has been cut for a long time. Therefore, the traditional threading processing technology has potential safety hazards and low production efficiency.

Abstract

The invention discloses a batch machining device and technology for reinforcing-steel-bar straight threads. The machining device comprises a left reinforcing-steel-bar straight thread machining device body, a right reinforcing-steel-bar straight thread machining device body, a left protective shed, a right protective shed and an automatic conveying platform for conveying to-be-machined reinforcing steel bars. The left reinforcing-steel-bar straight thread machining device body and the right reinforcing-steel-bar straight thread machining device body are used for machining the two ends of the to-be-machined reinforcing steel bars respectively. The automatic conveying platform is located between the two reinforcing-steel-bar straight thread machining device bodies. Each reinforcing-steel-bar straight thread machining device body comprises a reinforcing-steel-bar cutting device for cutting the to-be-machined reinforcing steel bars and a straight-thread threading machine for carrying out threading on the to-be-machined reinforcing steel bars. The automatic conveying platform comprises a reinforcing-steel-bar containing frame, a first transverse conveying frame, a threading machining frame and a reinforcing-steel-bar longitudinal movement mechanism. The machining technology includes the steps of 1, reinforcing-steel-bar lifting; 2, reinforcing-steel-bar cutting; 3, reinforcing-steel-bar secondary forward moving; 4, reinforcing-steel-bar threading; 5, reinforcing-steel-bar third-time forward moving.

Description

Technical field [0001] The invention belongs to the technical field of steel straight thread processing, and in particular relates to a batch processing equipment and batch processing technology for steel straight thread. Background technique [0002] Straight threaded connection of steel bars refers to the processing of straight threads at the ends of the steel bars, and the use of connecting sleeves with internal threads to connect the steel bars to achieve a mechanical connection technology of steel bars that transmits the tension and pressure of the steel bars. Rebar straight thread connection technology is a kind of steel bar and other strength connection technology. Because of its fast construction speed, low construction pollution, stable and reliable quality, can be processed in advance, saving construction period, moderate price, and good economy, the Ministry of Construction will use this technology. As ten new technologies are vigorously promoted, their scope of applic...
