Detailed Description
As shown in fig. 1-2, the steel plate length measuring device of the structure of the present invention comprises a control unit and a measuring unit; the control unit comprises a cylinder 3, the upper side of the cylinder is in threaded connection with a bottom plate 1 welded on the shearing machine through a cylinder lug 2, and the lower side of the cylinder is hinged with the measuring unit; the measuring unit comprises a swing rod 6, the rear side of the swing rod is hinged to the shearing machine through a swing rod lug seat 4, the middle part of the swing rod is hinged to the air cylinder, the front side of the swing rod is provided with a length measuring roller 11 matched with the steel plate, and a length measuring roller shaft 12 of the length measuring roller is connected to the front end of the swing rod through a bearing seat 10; the swing rod is also provided with an encoder 7, the encoder is connected with the swing rod through an encoder shaft 9 in a shaft coupling mode, belt pulleys 13 which are matched with each other are arranged at the end part of the encoder shaft and the end part of the length measuring roll shaft, and the two belt pulleys are connected in a matching mode through a toothed belt 14; and a photoelectric switch 5 for detecting the steel plate is also arranged below the shearing machine.
Preferably, the encoder 7 is connected to the rocker 6 via a transition flange 8.
Specifically, the steel plate length measuring device is arranged in the lower area of the front panel of the shearing machine 15, the transverse installation position of the shearing machine can be adjusted according to the interference condition of other parts of the shearing machine, and the distance between the length measuring roller and the steel plate after the length measuring roller is pressed to the steel plate is 300-500 mm from the edge of the steel plate. The main function is to measure the head cutting, tail cutting and daughter board sizing of the mother board cut by the head cutter. The welding bottom plate 1 and the swing rod lug seat 4 are fixed below the front panel of the shearing machine in a welding mode, and the vertical installation position and distance between the welding bottom plate 1 and the swing rod lug seat 4 are guaranteed. The cylinder lug seat 2 is fixed on the welding bottom plate 1 through a bolt, and the cylinder 3 and the cylinder lug seat 2 are hinged together through a copper sleeve and a pin shaft, so that the cylinder can stably swing without torsion in the operation process. The swing rod 6 and the swing rod lug seat 4 are hinged together through a copper sleeve and a pin shaft, and when the steel plate contacts the length measuring roller 11, the length measuring roller 11 rotates under the driving of friction force between the steel plate and the length measuring roller. The length measuring roller 11 is connected with the length measuring roller shaft 12 through a key, the length measuring roller shaft is connected with a corresponding belt pulley through a key, the length measuring roller shaft 12 is positioned through two bearing blocks 10 and bearings, and the bearing blocks 10 are fixed on a swing rod 6 with positioning grooves through bolts. The encoder shaft is positioned on the swing rod 6 with an internal concave hole through two sets of bearings, the encoder 7 is fixed with the transition flange 8 through bolts, the corresponding belt pulley is fixed with the encoder shaft through a key, and the two belt pulleys transmit the rotating speed through a toothed belt 14 with the same modulus. Therefore, the length measuring roller rotates to drive the encoder to rotate, and the walking length of the steel plate when contacting the length measuring roller can be calculated according to the rotating ring speed of the encoder and the diameter of the length measuring roller. When the steel plate is detected by the photoelectric switch 5, the roller way stops working, the cylinder drives the length measuring roller to press down, and the roller way continues working; when the photoelectric switch detects that no steel plate is arranged below, the cylinder drives the length measuring roller to lift.
The camber of a steel plate produced by rolling is in the range of 50-300mm, so the installation position of the length measuring roller ensures that the distance between the length measuring roller and the edge of the steel plate is 300-500 mm after the length measuring roller rolls to the steel plate, and the production and use requirements can be met. When the steel plate is conveyed to the front of the crop shear, the conveying roller way stops rotating, the crop shear is prepared before shearing, then the roller way runs at a low speed, when the photoelectric switch 5 detects the head of the steel plate, the air cylinder 3 is pressed down, the roller way is manually rotated at a low speed by an operator, and the length measuring roller simultaneously calculates the walking length of the steel plate. At the moment, the operator shears the head of the steel plate, and the length measuring roller encoder is cleared. And (3) continuously conveying the steel plate by an operator, measuring the length of the length measuring roller again, stopping the roller way when the length of the length measuring roller reaches the length required by the first sub-plate, starting shearing again, and resetting the length measuring roller after shearing. And when the last daughter board passes through the tail part of the steel plate detected by the photoelectric switch, the length measuring roller is lifted, the roller way stops running, and an operator shears the tail part of the steel plate. Thus, the head cutting, the tail cutting and the sectional length measuring of one mother board are completed.
