Technical Field

The invention relates to the field of reinforcing mesh welding equipment.

Background

The net sheets used by the concrete square culvert are formed by welding mutually vertical steel bars. The longitudinal ribs are arranged along the main shaft direction of the welding machine, and the transverse ribs are perpendicular to the longitudinal ribs. The longitudinal ribs are positioned on the lower electrode, the transverse ribs are positioned on the discharging mechanism, and the transverse ribs are generally positioned above the longitudinal ribs. The existing guiding device for the mesh welding equipment guides the transverse rib into the middle of an upper welding electrode and a lower welding electrode (an upper electrode and a lower electrode), and due to the existence of the mesh, after one transverse rib is welded, in order to weld the next transverse rib through integral movement, a gap is formed between the guiding device and the welding electrode, so that the transverse rib cannot be reliably guided into a correct position, and manual correction is needed.

The purpose of the invention is realized as follows: a mesh welding steel bar leading-in device comprises a discharging mechanism connected to a rack, an upper electrode connected to the rack through a first air cylinder, and a lower electrode fixedly connected to the rack, wherein the upper electrode and the lower electrode are both arranged on the front side of a discharging end of the discharging mechanism, the first air cylinder is vertically arranged, and the upper electrode is arranged right above the lower electrode and moves up and down; a stop block is connected to the upper part of the lower electrode; a gear rack mechanism, a crank rocker mechanism and a guide plate are arranged below the discharging mechanism; the rack-and-pinion mechanism comprises a rack and a pinion which are meshed with each other, the rack is vertically arranged, the upper end of the rack is connected with a vertical second cylinder, the second cylinder is connected with the rack, the pinion is connected with a pinion shaft, and the pinion shaft is supported on the rack; the crank and rocker mechanism comprises two cranks and a rocker, the two cranks are arranged up and down, one ends of the two cranks are hinged with the rocker, the other end of one crank is connected with the gear shaft, the other end of the other crank is connected with the supporting shaft, and the supporting shaft is connected to the rack; the guide plate is arc-shaped, the inner concave surface of the guide plate faces the discharge end of the discharging mechanism and is arranged below the discharge end of the discharging mechanism, the upper end of the guide plate is connected with the cross rod, the cross rod is connected with the rocker, and the lower end of the guide plate is arranged above the lower electrode and on the rear side of the stop block.

During welding, the transverse ribs are positioned on the discharging mechanism, and the longitudinal ribs are positioned on the lower electrode. The transverse ribs roll to the upper portions of the longitudinal ribs along the guide plates one by one from the discharging mechanism, the transverse ribs are located between the stop blocks and the lower ends of the guide plates, the crank rocker mechanism swings under the driving of the gear rack mechanism, the guide plates move upwards and retreat, the upper electrode presses the transverse ribs to perform welding operation, and after welding is completed, the net piece moves backwards to enter the next cycle to weld the next transverse rib.

When the transverse ribs are fixed, the guide plate extends in, and after the transverse ribs are positioned, the guide plate retreats, so that the existence of gaps is avoided, the transverse ribs are reliably guided into the correct positions, manual correction is not needed, and the welding effect is ensured.

In order to ensure that the transverse ribs are guided into the correct positions more stably, the number of the guide plates is at least two, the structure of each guide plate is the same, and the at least two guide plates are connected to the transverse rod at intervals.

In order not to influence the movement of the mesh after welding one transverse rib, the stop block is connected to the left side or the right side of the lower electrode through a bolt.

In order to facilitate the discharging of the transverse ribs, the discharging end of the discharging mechanism is arranged in a downward inclined mode.
