Description

Processing equipment for hollow welded wire mesh

Technical field

The invention belongs to the field of steel welded mesh processing, and particularly relates to the processing of hollow welded meshes.

Background technique

Welded steel mesh is a mesh in which longitudinal steel bars and transverse steel bars are arranged at a certain interval and are at right angles to each other, and all intersections are welded together by resistance spot welding. It is mainly used in reinforced concrete structures. The hollow welded mesh is to adapt to the impact of bosses, caissons, especially doors and windows in prefabricated residential concrete slabs, etc. during the paving process. Holes are made in the entire mesh to meet structural needs. The traditional processing method of welded wire mesh is manually cut after the entire welded wire mesh is produced. The cut material cannot be used and is only treated as waste. The amount of waste is large, which is not only economical but also low in production efficiency. Previously invented a method of producing hollow welded wire mesh on traditional welded wire mesh processing equipment, and adjusted the production process, changing the warp thread once to multiple distributed threading, and the weft thread cutting is reused while meeting the production requirements. In order to reduce production costs. However, the warp and weft threading methods of this method are manual distributed threading, which can only solve the problem of poor economy, but cannot meet the problem of continuous equipment production and low production efficiency.

Summary of the invention

The invention provides a hollow-type welded mesh processing equipment, which realizes the automatic continuous production of the hollow-type welded mesh processing while the steel bar materials are fully utilized, so as to meet the requirements of production efficiency.

In order to realize automatic continuous production, the processing equipment of the hollow welded wire mesh of the present invention adopts steel wire rods for feeding both the longitudinal and transverse steel bars, and the transverse steel bars are automatically fed from both sides of the welded mesh host, and are conveyed after straightening. To the welding part in the welding host and cut to length, the warp feed is completed by the warp conveying device at the front end of the welding host: the warp from the wire rod is straightened by the straightening mechanism and then enters the warp conveying device. The driving wheel is composed of the driving wheel and the driven wheel. The driving wheel is an integral structure and is connected to the power device. The driven wheel is individually controlled and can move radially relative to the driving wheel. The surface of the driving wheel and the driven wheel is coated to increase the resistance to the warp friction. Grind the coating. When the equipment is started, when there is no need to open a hole, only the weft straightening and cutting device at one end is turned on to produce the weft. The passive wheels in the warp conveying device are all pressed down, and the active and passive wheels use friction to support each warp to run in a normal step. Row welding. When the hole needs to be opened, first, the driven wheel controlled by the warp at the opening of the hole is lifted, so that the warp stops stepping, and at the same time, the cutter in the cutting device is dropped and positioned and cut at the corresponding position, and the rest of the warp is continuously stepped ; When stepping to the welding position, the weft straightening and cutting devices at both ends of the main machine work simultaneously, and the corresponding size of the weft is conveyed from the left and right directions according to the position of the hole; at this time, the longitude and weft outside the hole are welded, and the electrode in the hole stops Work, as the stepping progresses, holes that meet the requirements can be produced. After the hole production is completed, the passive wheel is pressed down, and the cutter is lifted to start the stopped warp. The mesh production continues to repeat the above steps and work continuously, cycling in turn. The mesh moves forward. When the production of a mesh is completed, it is cut at the shearing position to complete the production of a welded mesh.

It can be seen from the above that the use of this processing equipment to produce hollow welded wire mesh can realize continuous operation of the whole process of welded wire mesh production through automatic control. Compared with the previous manual step-by-step operation, the production efficiency is greatly improved, and the whole process can realize mechanical operation. The machining accuracy is also more precise.

The warp conveying device 7 can individually control the stepping of each warp, and each warp is equipped with a warp cutting device 10.

It can be seen from Figure 3 that the warp conveying device 7 is composed of a driving wheel 11 and a driven wheel 12. The driving wheel 11 is an integral structure connected to the power device to be driven to rotate, and the driven wheel 12 can be controlled individually and independently of the driving wheel 11. Make a radial movement. The driven wheel 12 in the conveying device 7 and the cutter 10a in the cutting device are integrated with each other, and the driven wheel 12 is detached when the cutter 10a is working through the connecting rod; the driven wheel 12 is compressed when the cutter 10a is detached. The surfaces of the driving wheel 11 and the driven wheel 12 are coated with a wear-resistant coating that increases friction with the warp.

The shape and position of the holes on the mesh will be changed in actual production, but as long as the basic principles of the present invention are involved, they fall within the protection scope of the present invention.
