Description

Technical Field

[0001] The utility model belongs to the technical field of processing and manufacturing grounding flat steel for electrical grounding systems, in particular to a horizontal bending and cold bending processing and manufacturing device for galvanized flat steel for grounding. Background Art

[0002] At present, the grounded galvanized flat steel horizontal elbows used on construction sites are processed in the following two ways: 1. On-site hot processing, that is, heating the area where the flat steel needs to be bent. When the flat steel is heated to a state that is easy to deform, manually apply stress to bend the flat steel to the required horizontal bending angle, and it can be used after cooling. Since heating treatment is required during the on-site production process, heating equipment or tools need to be prepared. At the same time, because the anti-corrosion and anti-rust function of the original galvanized layer is easily destroyed after the material is heated, the heated area needs to be re-treated with anti-corrosion and anti-rust; 2. Purchase finished horizontal elbows that match the required specifications and models of grounded galvanized flat steel. At the site of use, the horizontal elbows are welded to the grounded flat steel and then used. Welding equipment needs to be prepared. After welding is completed, the welding area needs to be treated with anti-corrosion and anti-rust. It can be seen that the above two methods not only require the preparation of corresponding equipment or tools in advance, but also require anti-corrosion and anti-rust treatment. The construction process is relatively cumbersome, resulting in time-consuming and labor-intensive.

[0003] Therefore, there is an urgent need to provide a galvanized flat steel cold bending processing device to simplify the construction method and improve construction efficiency. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a horizontal cold bending processing and manufacturing device for galvanized flat steel for grounding, which can perform cold bending processing on galvanized flat steel, simplify the operation steps and improve the construction efficiency.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A horizontal cold bending processing and manufacturing device for galvanized flat steel for grounding, comprising a hydraulic jacking pump and a mounting frame, wherein the mounting frame is rotatably connected to a pair of supporting wheels, and a first clamping groove for clamping the galvanized flat steel is provided along the circumference of one side of the supporting wheel;

[0007] A jacking die for bending galvanized flat steel is fixedly connected to the front end of the jacking rod of the hydraulic jacking pump, and the jacking die is located in the middle position of a pair of supporting wheels.

[0008] Furthermore, the mounting frame includes an upper panel and a lower panel, and both the upper panel and the lower panel are provided with positioning holes that are located opposite to each other;

[0009] Both ends of the support wheel are fixedly connected with positioning pins, which are inserted into the positioning holes.

[0010] Furthermore, the upper panel and the lower panel are both fixedly connected to the outer shell of the hydraulic jacking pump.

[0011] Furthermore, the lower panel and the hydraulic jacking pump are both equipped with wheels.

[0012] Furthermore, the wheels are self-locking wheels.

[0013] Furthermore, the lifting mold is cylindrical, and a second clamping groove for clamping the galvanized flat steel is opened along its circumference on one side, and the second clamping groove and the first clamping groove are in opposite directions.

[0014] Compared with the prior art, the utility model has the following technical effects:

[0015] The two ends of the galvanized flat steel are clamped by the first clamping groove opened on the side of a pair of supporting wheels, and then the hydraulic jacking pump is used to drive the jacking die to extrude the middle part of the galvanized flat steel, so as to bend the middle part of the extruded galvanized flat steel. The bending process is a cold bending process. Since no heating or welding is required, the galvanized protective layer on the surface of the galvanized flat steel will not be damaged. Therefore, there is no need to perform anti-corrosion and anti-rust treatment on the bent area of ​​the galvanized flat steel again, which simplifies the operation steps and improves construction efficiency.

[0016] The middle part of the galvanized flat steel is fixed by the second clamping groove provided on one side of the jacking die, so that the position of the galvanized flat steel is prevented from being shifted during the bending process, thereby improving the qualified rate of the bending forming process.
