Background

The section is the square package structure after the band steel pile up neatly, has finished tying through the automatic bundling machine of square package, and the kink head direction is 45 degrees in the oblique upper direction, and the bundling machine does not have the function of subsequent processing kink head. Because finished products need to be in a stacking structure after being put in storage, the kinking head of each bundle of flat steel can cause surface damage such as scratch or crush damage to the bottom surface of the previous layer of flat steel bundle, and the surface quality of the products is directly influenced.

At present, the bending or clinching is carried out manually by using tools, about 1600 structural heads to be processed in each class are adopted, a packing wire adopts HPB300 wire coils with the diameter of 7mm, the twisting head is required to be bent, at least 25 kgf.m of torque is obtained through field measurement, the labor intensity of workers is very high, the bending angle of the twisting head is different from person to person, the strength is low, and the bending angle is insufficient, so that the effect cannot be achieved. Although various tools with different lengths are manufactured, the tools are too long and inconvenient to use, the efficiency is low, safety risks are brought, the tools are short, the operation is convenient, the efficiency is high, and some staff cannot pull the tools.

Disclosure of Invention

The invention aims to provide a flat steel bundle heading machine which is simple in structure, convenient to use, capable of reducing the labor intensity of workers and improving the production efficiency, and the heading effect of the flat steel bundle heading machine is superior to that of a manual heading machine.

The invention relates to a flat steel bundling press head machine, which comprises a press wheel, a press wheel bracket, a cantilever bracket, a cylinder and a hydraulic cylinder, wherein the hydraulic cylinder is arranged on a bundling machine; the movable end at the pinch roller support is installed to the pinch roller, and the pinch roller comprises roller, distance cover, jump ring, bearing, running roller, and the roller links to each other with the pinch roller support, and the running roller passes through distance cover, jump ring and bearing and installs on the roller.

The working principle of the flat steel bundle heading machine is that a hydraulic cylinder drives a cantilever bracket to rotate around a rear rotating shaft, a cylinder controls a pinch roller bracket to rotate around a front rotating shaft, and a pinch roller moving along with the pinch roller bracket bends a flat steel bundle twisting head which is not processed in a subsequent process of the binding machine. The specific working process is that the flat steel bundles are transported in the roller way, the positions of the bundle twisting heads are aligned with the working area of the heading machine through the inching of the operation roller way, namely the working range of the roller surface of the pinch roller is within 500mm, at the moment, the following actions are sequentially completed through the operation equipment, the initial working state of the heading machine is shown in figure 1, the piston rod of the hydraulic cylinder is in an extending state, and the piston rod of the cylinder is in a retracting state. Step 1 (see figure 4), a piston rod of an air cylinder extends out to push a pinch roller bracket to drive a pinch roller to rotate around a front rotating shaft, and the next step is carried out after the pinch roller bracket is completed; step 2 (see fig. 5), a piston rod of the hydraulic cylinder is retracted, the cantilever bracket is pulled to rotate around the rear rotating shaft, at this time, a pinch roller bracket, a pinch roller, an air cylinder and the like which are arranged on the cantilever bracket swing downwards along with the cantilever bracket, the flat steel bundle and the kinking head are just in the range of the radius of gyration action of the pinch roller, the dead weight of the flat steel bundle is about 2.5 tons and is in a static state, the kinking head cannot block the motion of the pinch roller and is bent, the pinch roller moves along the outer surface of the flat steel bundle under the continuous thrust of the air cylinder and bends the kinking head, the air cylinder plays a role of compressing a spring in the process, and the principle of compressibility of air is mainly utilized, and the next step is carried out after the completion; step 3 (see fig. 6), the air cylinder controls the piston rod to retract through the reversing valve, the pressing wheel is driven to be separated from the outer surface of the flat steel bundle, preparation work is carried out for the next action, the bent kinked head is mainly prevented from being tied up in the next action process, and the next step is carried out after the operation is finished; and 4 (see fig. 7), the hydraulic cylinder controls the piston rod to extend out through the reversing valve, the cantilever frame is driven to swing upwards around the rear rotating shaft, and the heading machine returns to the initial position at the moment, so that a heading cycle is completed.

The flat steel bundle pressing head machine is directly installed on the existing bundling machine, adopts mechanical automation to press and bend the flat steel bundle twisting head, can reduce the labor intensity of workers and improve the production efficiency, can avoid scratching or pressing the bottom surface of the flat steel bundle, and has the advantages of convenient use, high safety performance and the like.

Detailed Description

A flat steel bundle pressure head machine comprises a pressure wheel 4, a pressure wheel support 5, a cantilever bracket 6, a cylinder 7 and a hydraulic cylinder 8, wherein the hydraulic cylinder 8 is installed on a bundling machine, and the flat steel bundle pressure head machine is characterized in that one end of the cantilever bracket 6 is arranged on the bundling machine through a rear rotating shaft 9, the movable end of a piston rod of the hydraulic cylinder 8 is fixed between two end heads of the cantilever bracket 6, the other end of the cantilever bracket 6 is connected with the pressure wheel support 5 through a front rotating shaft 3, and two ends of the cylinder 7 are respectively fixed on the cantilever bracket 6 and the pressure wheel support 5; the pinch roller 4 is installed at the loose end of pinch roller support 5, and pinch roller 4 comprises roller 41, distance cover 42, jump ring 43, bearing 44, running roller 45, and roller 41 links to each other with pinch roller support 5, and running roller 45 passes through distance cover 42, jump ring 43 and bearing 44 and installs on roller 41.

And the cantilever frame 6 is provided with a limit switch 10 which is used for transmitting the position information of the cantilever frame 6 to an electrical control room, so that the automatic control operation of the heading machine is facilitated.

The roll shaft 41 is a smooth rod without a shaft shoulder, so that the roll shaft is convenient to disassemble and assemble; distance sleeves 42 are arranged at two ends respectively, and play a role in axial positioning; the clamp springs 43 are arranged at two ends of the roller 45 respectively and are arranged in grooves of inner rings at two ends of the roller to play a role in fixing the outer ring of the bearing 44; the bearings 44 are deep groove ball series bearings, and are characterized in that the bearings can bear axial force and radial force at the same time, and because the main stress or the main radial force of the compression roller device is adopted, two sets of bearings 44 are respectively arranged at two ends in the roller 45, and the four sets of bearings are used together, so that the integral bearing capacity of the compression roller is enhanced. The length of the whole working surface of the pinch roller 4 is 500mm, the length is too short, the twist head 2 is difficult to align, the operation difficulty is increased, and the length is too long, so that the occupied space of the equipment is large, and the equipment is not easy to install.
