Description
Technical Field
The utility model relates to a steel band pay-off correlation technique field specifically is steel band pay-off width monitoring and automatic stop device.
Background
In the existing stamping production, the monitoring means for the width of the steel strip is few, the width tolerance of the steel strip is mainly guaranteed by a steel mill or a steel strip cutting manufacturer, although the measurement can be carried out in the actual production of the steel strip, the deviation exists when the coil stock is uncoiled due to the uneven thickness and density of materials in the actual production, the width of a single coil of the steel strip is extremely easy to be uneven, after the coil stock is uncoiled, the alignment is hardly guaranteed at the edge of the coil stock due to burrs generated in the cutting process. Therefore, in the actual stamping production, local measurement and sampling measurement are generally adopted for measuring the width of the steel strip, after one roll of steel strip is unpacked, multi-point measurement can be carried out on the outer side of the coil by using a caliper, and the measurement mode can be used for measuring the local size of the coil; then, a section of steel strip can be cut, and only the width dimension of a single steel strip is measured, so that the measurement accuracy is high.
The existing steel belt feeding mode for stamping production is that a steel belt is directly conveyed to a die feeding hole by a feeding machine, in order to ensure that the center of the steel belt is coincided with the center of the die, a striker plate can be arranged at the die steel belt feeding hole under the general condition, the width of the striker plate has a certain gap with the steel belt, and a coil can smoothly pass through the striker plate to feed under the general condition. Because the precision of the cutting edge of the die is high, the cutting edge of the die is prevented from being damaged by padding and the like in stamping production, and an automatic stopping device is generally used. The induction part of the height induction device is arranged on the lower surface of the discharging plate of the die, and the gap between the discharging plate and the lower die is mainly compared with the thickness of a punching material through the height sensor, so that whether padding and the like occur or not is determined, and the punching equipment is controlled to stop automatically. The induction part of the position induction device is arranged on the upper die of the die, and whether the position deviation of the existing hole slot exceeds the set range is mainly induced, so that whether the conditions such as feeding error occur or not is determined, and the stamping equipment is controlled to stop automatically.
There are the following disadvantages: 1. when the caliper is used for measuring the local size of the coil stock, the actually measured data has large deviation due to uneven edges, and the data can only be used for reference; 2. when the size of a single steel strip is measured in a sampling mode, the sampling measurement mode is different from random sampling, and only the stub bar part of a coil material can be measured, so that the size of the whole coil of steel strip cannot be accurately measured; 3. the steel belt slides in the striker plate during conveying, and when the width exceeds the inner width of the striker plate, the steel belt can be clamped in the striker plate opening, so that feeding is not smooth, feeding is not in place seriously, and stamping dislocation is directly caused; 4. when the width is smaller than the proper width, the steel belt is just deviated to one side of the material baffle plate, so that uneven feeding is easy to occur, and material lifting errors or material defects are easy to occur in subsequent stamping; 5. the principle of an induction device in the die is that the die can be stopped in an induction mode when a stamping error occurs, so that the cutting edge is extremely easy to damage, and the service life of the die is shortened; therefore, the utility model provides a steel band pay-off width monitoring and automatic stop device is used for solving above-mentioned problem.
