Description

Technical Field

[0001] This utility model relates to mesh covering hook welding equipment, specifically referring to the primary bending device of a mesh covering hook welding machine. Background Technology

[0002] The main structure of the composite steel mesh insulated exterior wall panel consists of main reinforcing meshes on both sides of a graphite polystyrene board, with secondary reinforcing meshes spaced apart on the outside of the main reinforcing meshes to form a frame. The two ends of the steel wires pass through the graphite polystyrene board and are welded to the main reinforcing meshes and secondary reinforcing meshes respectively. The steel wire mesh is attached to the surface of the secondary reinforcing meshes. The only difference between the composite steel mesh insulated interior wall panel and the composite steel mesh insulated exterior wall panel is that the latter does not contain graphite polystyrene board. Because of the impact of concrete during use, the steel wires are prone to detaching from the main and secondary reinforcing meshes. Therefore, bending the exposed ends of the steel wires on the secondary reinforcing mesh surface is an essential structural feature of existing products. This structure maintains product stability even after the steel wires detach from the main and secondary reinforcing meshes. Currently, there is no dedicated equipment to perform this bending operation, which is mainly done manually using simple non-standard tools. The problems with this operation are: firstly, low standardization and efficiency of manual operation; secondly, the use of tools can easily damage the mesh frame; thirdly, high labor costs; and fourthly, incomplete bending can cause the wires to become entangled during product stacking and transportation, leading to inconvenience. If automated equipment is used to produce composite steel mesh insulation wall panels, bending the exposed ends of the welded steel wires is an essential process and key technology for completing the above operations.

[0003] The applicant has retrieved the following existing patent documents:

[0004] Patent document CN213564459U discloses a vertical steel wire mesh insulation board forming machine. The welding of the inserted wires to the main reinforcing mesh is achieved through a wire insertion device and a welding device. However, the welding device uses existing technology, and the exposed ends of the welded steel wires cannot be bent by the equipment. Therefore, once the steel wires detach from the mesh, they will fall off. The applicant has not found any documents identical or similar to this utility model in domestic patent databases. Summary of the Invention

[0005] The purpose of this utility model is to provide a bending device for a wire mesh hook welding machine, which can effectively bend the exposed ends of the welding wires on the main reinforcing mesh with different thicknesses, thereby greatly improving the standardization and speed of the bending operation.

[0006] The overall technical concept of this utility model is:

[0007] The primary bending device of the wire mesh hook welding machine includes a main frame and a movable frame set on the main frame to form a conveying channel. The movable frame and the main frame are reciprocated and the spacing is adjustable along the direction perpendicular to the conveying channel by a drive mechanism. Supports are symmetrically set on the movable frame and the main frame on both sides of the conveying channel behind the welding station. The shaft is driven by a cylinder set on the support to move reciprocally along the longitudinal direction. Fixed plates are set at intervals along the longitudinal direction on the support adjacent to the conveying channel. Movable blocks are fixed at intervals along the longitudinal direction on one side of the shaft adjacent to the conveying channel. The movable blocks are provided with a working surface for bending the exposed ends of the steel wires welded to the main and secondary reinforcing mesh through relative movement with the fixed plates.

[0008] The applicant should clarify that the adjustable distance between the movable frame and the main frame not only allows the conveying channel to accommodate main reinforcing meshes of different widths, but also meets the technical requirements for precise positioning during subsequent welding wire and bending operations, enabling continuous production with accurate positioning of the welding and bending of the steel wire, main reinforcing mesh, and secondary reinforcing mesh. The bending operation is achieved by a cylinder driving a fixed block on the shaft and a movable plate on the support to gradually push each other in a staggered motion. The structural design of the working surface is intended to improve the stress on the steel wire and provide a bending support, preventing excessive shear force on the steel wire that could cause damage or displacement of the bent part from the set position.

[0009] Other specific technical solutions of this utility model include:

[0010] To facilitate the reciprocating cooperation between the movable frame and the main frame and to enable flexible movement when adjusting the spacing, the preferred technical means is that the bottom of the movable frame is assembled with the main frame via guide rails and guide wheels in a direction perpendicular to the conveying channel.

[0011] The bending operation of the exposed end of the steel wire is achieved through the vertical offset movement between the movable block and the fixed plate. However, if both working surfaces are planar, the shear force on the steel wire during offset will be too great, making it difficult to determine the bending point or causing the wire to break. This is detrimental to ensuring effective bending quality. If the bending point deviates, it will damage the main and secondary reinforcing meshes or render the operation meaningless. A preferred technical solution is to use a sloping working surface. This allows the force on the steel wire to gradually increase during the vertical offset between the movable block and the fixed plate, gradually increasing the bending angle until the wire is bent at the designated position, thus improving bending accuracy and quality.

[0012] To facilitate the installation of the shaft and cylinder while ensuring structural stability during operation, the preferred technical solution is that the bracket includes columns on both sides of the shaft, a base plate fixed to the bottom of the columns for connection with the main frame or movable frame, and the cylinder is fixed to the top of the columns via a connecting bracket, with its power output end connected to the upper end of the shaft.

[0013] Furthermore, in order to effectively ensure the accuracy of the longitudinal movement of the shaft and thus improve the operational precision of the bending operation, the preferred technical means is to have the bottom of the shaft and the bushing set on the bracket slide together.

[0014] The technological advancements achieved by this utility model are as follows:

[0015] 1. This utility model adopts a structure design of cylinder, shaft and bracket. The structure design realizes the bending operation of the exposed end of steel wire by the vertical misalignment of the fixed block and the movable plate. The positioning and bending operation of the exposed end of steel wire is accurate and easy to achieve standardized and fast operation.

[0016] 2. This utility model adopts a structural design with a sloping working surface. When the moving block and the fixed plate are misaligned, the force on the steel wire gradually increases, and the bending angle gradually increases until it is bent into place at the set position, ensuring bending accuracy and quality.

[0017] 3. The structural design of the bracket, bushing, and shaft effectively ensures the straightness of the longitudinal movement of the shaft, thus providing a reliable structural guarantee for accurate positioning during bending operations.

[0018] 4. The adjustable spacing between the movable frame and the main frame is designed to facilitate the conveying of main rib meshes of different thicknesses. Furthermore, since welding wire and bending devices can be installed on the movable frame and the main frame, this structural design ensures precise adjustment of the workstation during welding wire and bending operations.

[0019] 5. This utility model adopts a structural design of guide wheels and guide rails, which improves the flexibility of component matching, facilitates the reduction of load and work intensity when adjusting the spacing. Attached Figure Description
