Description

Technical Field

[0001] This utility model relates to the technical field of stencil bending and welding equipment, specifically a stencil bending and welding machine. Background Technology

[0002] Existing construction steel mesh panels are divided into straight mesh panels and hooked mesh panels, used as reinforcing bars in concrete pouring for buildings. Straight mesh panels are tied together with steel wire, while hooked mesh panels are connected with hooks, resulting in a more stable and reliable connection compared to straight mesh panels. Currently, there is no equipment on the market specifically for producing hooked mesh panels. The traditional production process involves bending the steel bars used as transverse reinforcement, manually tying the bent transverse and longitudinal reinforcement bars, and finally welding them together. This process involves many steps, requires a large production area, and is complex.

[0003] A prior art stencil bending and welding machine with application number 201821613232.4 includes a welding mechanism, a stepping mechanism, and a bending mechanism. The stepping mechanism includes a slide rail support and a conveying device. The welding mechanism includes a welding base, a feeding device, and a welding unit. The feeding device contains a material fixing pipe. The welding unit includes a welding head, a welding table, a storage tank, and a sensor. One end of the conveying device is connected to the welding base. The bending mechanism includes a bending base, a transverse track, a movable base plate, a longitudinal track, and a machine body. The machine body has a hollow groove, and a transverse groove is opened on one side of the machine body. A processing plate is placed in the transverse groove. A first cylinder and a second cylinder are fixed at the upper part of the machine body. One end of the first cylinder is connected to a first push rod and a pressure rod, and one end of the second cylinder is connected to a second push rod and a pressure plate. This utility model has a welding mechanism and a bending mechanism, which can sequentially complete stencil welding and stencil bending processing. The equipment has a small footprint, the processing is fully automatic, saves manpower, and has high production efficiency. However, it is difficult to achieve the purpose of arc bending and welding processing, and the bending and welding processing efficiency is relatively low. Utility Model Content

[0004] The purpose of this invention is to provide a wire mesh bending and welding machine to solve the problems of difficulty in achieving arc bending and welding processing in the prior art, and the low efficiency of bending and welding processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mesh bending and welding machine, comprising a base, a top plate provided on the upper side of the base via a vertical plate and a column, a bending inner cylinder provided in the middle of one side of the vertical plate via a support shaft, a connecting roller rotatably provided on the upper side of the base via a support plate and a connecting shaft, a bending pressure plate provided on one side of the connecting roller, and a hydraulic cylinder connected to one end of the two connecting shafts via a gear and rack assembly, a transverse sliding block provided on the top of the top plate via a lead screw, and a welding head provided at the lower end of the transverse sliding block via an electric push rod, with one end of the welding head electrically connected to a welding machine.

[0006] Furthermore, the support plate, connecting shaft, connecting roller and bending pressure plate are symmetrically arranged in two sets about the center of the base, and the two connecting rollers are arranged in parallel.

[0007] Furthermore, the bending sheet is an arc-shaped sheet, and the bending sheet has an alloy structure.

[0008] Furthermore, one end of the bending sheet is provided with a groove, and a bending roller is rotatably disposed in the groove via a rotating shaft.

[0009] Furthermore, the gear and rack assembly includes a driven gear disposed at one end of the connecting shaft, and a driving rack that meshes with the two driven gears is disposed at one end of the hydraulic cylinder.

[0010] Furthermore, the hydraulic cylinder is fixedly mounted on one side of the vertical plate by a support base, and the active rack is arranged perpendicular to the connecting roller.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention involves placing the material to be bent and welded flat on top of two connecting rollers. Then, a hydraulic cylinder and a gear rack drive the two connecting rollers and the bending pressure plate to rotate in opposite directions for adjustment. This allows the flat mesh to be bent into an arc shape outside the inner cylinder. Then, a lead screw drives a transverse slider, an electric push rod, and a welding head to move laterally to perform welding and stitching on the bending opening, thereby achieving the purpose of arc bending and welding processing. Moreover, the bending and welding processing efficiency is relatively high.

[0013] This invention features a groove at one end of a bending sheet, with a bending roller rotatably mounted within the groove via a rotating shaft. This reduces the friction between the bending sheet and the flat mesh during bending, thus improving the smoothness of bending the sheet.

[0014] In this invention, a hydraulic cylinder is connected to one end of each of the two connecting shafts via a gear and rack assembly. The gear and rack assembly includes a driven gear at one end of the connecting shaft and a driving rack at one end of the hydraulic cylinder that meshes with the two driven gears. This allows the hydraulic cylinder to drive the driving rack to rise and fall, thereby enabling the two driven gears to rotate in opposite directions for adjustment. Moreover, the transmission stability is high, which helps to improve the stability of the connecting roller and the bending sheet during rotation and bending. Attached Figure Description

A hydraulic cylinder 1 is connected to one end of the two connecting shafts 10 via a gear and rack assembly. 4. The hydraulic cylinder 14 and the gear rack set drive the two connecting rollers 11 and the bending pressure plate 12 to rotate in opposite directions for adjustment, so that the flat mesh plate can be bent into an arc shape outside the bending inner cylinder 19. The top of the top plate 3 is provided with a transverse slider 5 through the lead screw 4, and the lower end of the transverse slider 5 is provided with a welding head 7 through the electric push rod 6. One end of the welding head 7 is electrically connected to a welding machine 8.

The hydraulic cylinder 14 is fixedly disposed on one side of the vertical plate 2 by a support base, and the driving rack 15 is disposed perpendicular to the connecting roller 11, so that the driving rack 15 is driven by the hydraulic cylinder 14 to adjust the height, thereby enabling the two driven gears 13 to rotate in opposite directions for adjustment. Moreover, the transmission stability is high, which facilitates the improvement of the stability of the rotation and bending of the connecting roller 11 and the bending sheet 12.

[0025] The working principle and usage process of this utility model are as follows: When in use, the part to be bent and welded is placed on the upper part of the two connecting rollers 11. Then, the two connecting rollers 11 and the bending pressure plate 12 are driven to rotate in opposite directions by the hydraulic cylinder 14 and the gear rack group, so that the flat mesh plate can be bent into an arc shape outside the bending inner cylinder 19. Then, the transverse slider 5, electric push rod 6 and welding head 7 are driven by the lead screw 4 to move laterally to weld the bending opening, thereby achieving the purpose of arc bending and welding processing. Moreover, the bending and welding processing efficiency is high.
