Abstract
Description
Technical Field
[0001] This utility model relates to the field of CNC shearing machine technology, and in particular to an anti-warping device for CNC shearing machines. Background Technology
[0002] A shearing machine is a machine that uses one blade to reciprocate linearly relative to another blade to shear sheet metal. It uses a moving upper blade and a fixed lower blade, with a reasonable blade gap, to apply shearing force to metal sheets of various thicknesses, causing the sheet metal to break and separate to the required dimensions.
[0003] However, some problems still exist in its use. For example, when cutting metal sheets, existing shearing machines often use clamping devices to hold the sheets before cutting. When cutting bent or wrinkled thin metal sheets, warping is likely to occur, which affects the processing accuracy. Therefore, the workpiece needs to be flattened before cutting, but this involves more steps and is not convenient to use. Therefore, an anti-warping device for CNC shearing machines is proposed to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide an anti-warping device for CNC shearing machines, which has the effect of high cutting accuracy.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an anti-warping device for a CNC shearing machine, comprising a shearing machine body, a plate clamping component and an anti-warping assembly provided on the right side of the shearing machine body, the anti-warping assembly comprising a plate feeding frame fixed to the right side of the shearing machine body, two symmetrical clamping plates and a screw component for adjusting the distance between the two clamping plates provided on the upper end surface of the plate feeding frame, and a pressure roller structure provided on the inner side of the clamping plates.
[0006] By adopting the above technical solution, the metal sheet is placed on the feeding frame, and the distance between the two clamping plates is adjusted by the lead screw to make both ends of the metal sheet close to the clamping plates. Then, the metal sheet is pressed down by the pressure roller structure to make it flat and convey it into the main body of the shearing machine. During the cutting process, the sheet is fixed by the plate clamping component to ensure that the sheet is cut accurately and avoid the problem of warping edges.
[0007] A further feature of this invention is that the pressure roller structure includes a side plate fixed to the upper end of the clamping plate, a movable plate is installed at the lower end of the side plate, a plurality of pressure rollers are equidistantly installed at the bottom of the movable plate, and a drive component for controlling the downward movement of the pressure rollers is also provided on the plate feeding frame.
[0008] By adopting the above technical solution, the moving plate and the pressure roller are controlled by the drive component to move downward, so that the pressure roller can stably press the metal plate and avoid the problem of edge warping. At the same time, the metal plate can be conveyed towards the main body of the shearing machine.
[0009] A further feature of this invention is that the driving component includes a threaded sleeve rotatably mounted on the side plate, and a screw threadedly adapted to the threaded sleeve is fixedly mounted on the upper end face of the movable plate.
[0010] By adopting the above technical solution, the threaded sleeve is rotated, causing the screw to be pushed downward by the thread force, which in turn pushes the moving plate and the pressure roller downward as a whole.
[0011] A further feature of this invention is that the top of the plate feeding frame is provided with two symmetrical fixing blocks, a first motor is installed on one of the fixing blocks, a telescopic rotating rod is installed at the output end of the first motor, two symmetrical worm gears are provided on the telescopic rotating rod, and a worm wheel adapted to the worm gear is fixedly installed on the outside of the threaded sleeve.
[0012] By adopting the above technical solution, the telescopic rotating rod and the worm gear are driven to rotate as a whole by the first motor, which can drive the worm wheels on both sides to rotate synchronously, thereby controlling the rotation of the threaded sleeve and pushing the moving plate and the pressure roller down as a whole.
[0013] A further feature of this invention is that the telescopic rotating rod includes a connecting rod that connects two worm gears to opposite sides, a sleeve is slidably installed between the two connecting rods, four sliding blocks are installed at one end of the connecting rod extending to the sleeve, and an opening is provided on the side wall of the sleeve for the slider to slide back and forth.
[0014] By adopting the above technical solution, when the distance between the clamping plates on both sides changes, the connecting rods at both ends slide in the sleeve, and when one connecting rod rotates, the other connecting rod will also rotate under the action of the sliding block, so that the movement of the clamping plate will not affect the lifting and lowering of the moving plate and the pressure roller.
[0015] A further feature of this invention is that the lead screw component includes a second motor installed at the lower end of the plate feeding frame, and a bidirectional lead screw is installed at the output end of the second motor. The bottom of the clamping plate is threadedly connected to the bidirectional lead screw.
[0016] By adopting the above technical solution, the second motor drives the bidirectional lead screw to rotate, thereby adjusting the distance between the two clamping plates, thus satisfying the limit on metal plates of different widths and avoiding the problem of displacement.
[0017] A further feature of this invention is that the plate feeding frame is provided with a slot for sliding the clamping plate, and two guide rods adapted to the sliding of the clamping plate are installed in the slot.
[0018] By adopting the above technical solution, the sliding of the clamp plate is made more stable through the sliding cooperation between the groove and the guide rod.
[0019] A further feature of this invention is that the plate clamping component includes a fixed plate installed on the right side wall of the shearing machine body, an electric push rod is installed on the fixed plate, a U-shaped seat for fixing the plate is installed at the output end of the electric push rod, and two limiting rods that are slidably adapted to the fixed plate are installed on the top of the U-shaped seat.
[0020] By adopting the above technical solution, after the metal sheet is positioned, the U-shaped seat is moved down by the electric push rod, so that the metal sheet is stably pressed and prevented from being misaligned or warped during cutting.
[0021] The beneficial effects of this utility model are:
[0022] 1. This utility model uses a second motor to drive a bidirectional lead screw to rotate, thereby adjusting the distance between the two clamping plates to meet the limiting requirements for metal plates of different widths. Then, the first motor drives the telescopic rotating rod and the worm gear to rotate as a whole, which can drive the worm wheels on both sides to rotate synchronously, thereby controlling the rotation of the threaded sleeve, pushing the moving plate and the pressure roller down as a whole, making them flat and conveying them into the shearing machine body, so that the plate is precisely cut and avoids the problem of warping edges.
[0023] 2. In this utility model, after the metal sheet is positioned, the U-shaped seat is moved down by the electric push rod, so that the metal sheet is stably pressed, which makes the metal sheet more stable during cutting and further improves the cutting accuracy of the metal sheet.
