Technical Field

[0001] The present invention relates to the field of mechanical processing, in particular to a metal plate processing device. Background Art

[0002] During the production process of metal sheets, some industries have certain requirements for the thickness and width of the metal sheets used. In order to meet the supply requirements of such metal sheet products, the produced metal sheets need to be cut to size. Currently, there are many shearing machines to choose from for the processing of metal sheets, but the existing shearing machines still have many problems. For example, during the processing of metal sheets, due to human errors, materials of different widths of the metal sheets to be processed are fed into the shearing machine, resulting in feeding errors. Summary of the Invention

[0003] The purpose of the present invention is to remedy the defects of the prior art and provide a shearing machine with a width detection function to avoid the problem of feeding errors caused by human error when materials with different widths from the metal plates to be processed are fed into the shearing machine.

[0004] Specifically, the technical solution of the present invention is:

When the difference does not exceed the tolerance range required by the predetermined order, the shearing device starts and executes the metal sheet shearing program; otherwise, the shearing device does not start, and controls an alarm device to sound an alarm to remind the operator to replace the metal sheet.

[0006] Furthermore, the displacement sensor includes a variable resistor slide, a sensor slide and a data processor. The sensor slide is connected to the material stop seat one by one. When the material stop seat slides on the slide, it will drive the sensor slide to slide on the variable resistor slide, causing the resistance on the variable resistor slide to change. The data processor can obtain the distance moved by the material stop seat based on the change in resistance to calculate the width of the metal plate.

[0007] Furthermore, a supporting roller is provided in the support frame, and the supporting roller is used to support and transport the metal plate.

[0008] Furthermore, a screw is provided in the support frame, and the screw is driven by a motor externally connected to the support frame. Driven by the motor, the screw can drive the material blocking seat to move axially along the slide rail.

[0009] Furthermore, the straightening mechanism includes a straightening bracket, in which a bottom straightening roller layer and a top straightening roller layer are provided. The bottom straightening roller layer is fixed on the straightening bracket, and the top straightening roller layer is connected to the straightening bracket through a lower pressure screw and is connected to a lower pressure motor. The lower pressure screw is driven by the lower pressure motor to control the lifting and lowering of the top straightening roller layer. The straightening mechanism can extrude the metal plate material to be processed through the top straightening roller layer and the bottom straightening roller layer inside it to change its straightness, thereby achieving the purpose of straightening.

[0010] Furthermore, the transfer mechanism is a guide roller, and the guide roller can rotate to drive the metal plate to move.

[0011] Furthermore, an alarm device is provided in the control device, and the alarm device is an alarm for promptly reminding the operator when the shearing machine fails, so as to avoid losses caused by various accidents.

[0012] Furthermore, the shearing device is provided with a discharge port, and the discharge port is provided with a material receiving mechanism, and the metal plates that have completed shearing will be collected in the material receiving mechanism.

[0013] The beneficial effects of the present invention are as follows: the present invention provides a width detection device at the discharge end of the metal plate conveying device, after the metal plate enters the width detection device, the sensor trigger device in the width detection device is triggered by the control device, the displacement sensor starts to detect the width of the metal plate, and compares the detected width data with the width required by the predetermined order. When the difference does not exceed the tolerance range required by the predetermined order, the shearing device starts and executes the metal plate shearing program. Otherwise, the shearing device does not start, and controls the alarm device to sound an alarm to remind the operator to replace the metal plate. After the operator has handled the error, normal processing is resumed to avoid feeding errors causing property losses to the company. BRIEF DESCRIPTION OF THE DRAWINGS

A material stop roller 13 is provided in the material stopper seat 12, and the material stop roller 13 is used to clamp the metal plate.

[0019] In this embodiment, after the metal plate enters the discharge end 5 of the metal plate conveying device 1, the sensor triggering device 10 will be triggered, and the control device 3 will control the width detection device 7 to start; the motor 19 in the width detection device 7 drives the screw rod 18 to move and drive the material blocking seat 12 to slide in the axial direction of the slide rail 11 until the material blocking roller 13 in the material blocking seat 12 clamps the metal plate. Since the material blocking seat 12 is connected to the sensor slide 15, when the material blocking seat 12 slides in the axial direction of the slide rail 11, it will also drive the sensor slide 15 to slide on the variable resistor slide 14. The resistance of the variable resistor slide 14 will change with the sliding of the sensor slide 15, and the data processor 16 obtains the The distance moved by the material stop seat, since the sensor slide 15 is connected one-to-one with the two material stop seats mounted on the slide rail, the data processor 16 will obtain the data of the two sets of displacement sensors, and the width data of the metal plate can be obtained by the sum of the two sets of displacement data. The width data of the metal plate will be transmitted to the control device 3 and compared with the width required by the predetermined order. When the difference does not exceed the tolerance range required by the predetermined order, the shearing device 2 starts and executes the metal plate shearing program; the metal plate conveying device 1 can normally feed the material to the shearing device 2 and process it; otherwise, the shearing device 2 will not start, and the alarm device in the control device 3 will trigger the alarm to remind the operator to deal with it in time to avoid feeding errors and causing property losses to the company.

[0020] Preferably, after the metal plate enters the feed end 4 of the metal plate conveying device 1, it will also pass through a straightening mechanism, in which a straightening bracket 20 is provided, and a bottom straightening roller layer 21 fixed on the straightening bracket 20 is provided in the straightening mechanism, and the top of the straightening bracket 20 is connected to a top straightening roller layer 22 through a lower pressing screw 23, and the lower pressing screw 23 is driven by a lower pressing motor 24 to drive the top straightening roller layer 22 to move up and down; when the metal plate enters the straightening mechanism, the lower pressing motor 24 drives the lower pressing screw 23 to press the top straightening roller layer 22 downward, and the metal plate is squeezed by the top straightening roller layer 22 and the bottom straightening roller layer 21 while moving forward, and its straightness will change, and the surface will become smoother, which is convenient for subsequent shearing processing. After the metal plate is straightened, the guide roller 25 in the transfer mechanism 6 rotates and drives the metal plate to move forward at a constant speed, enters the shearing device 2 to complete the shearing process, and the processed metal plate is collected from the discharge port 26 into the receiving mechanism 27.
