[0004] The object of the present invention is to provide a cutting device for producing wires and cables to solve the problems raised in the above-mentioned background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a cutting device for manufacturing wires and cables, comprising a workbench and a support block, and also comprising a cutting assembly, a limiting device, a grinding device and a support device; the cutting assembly comprises a turntable, a tooth one, a cutter, a motor, a transmission gear, a cylinder and a guide plate, the turntable is rotatably connected to the right side of the support block, the tooth one is fixedly connected to the inner wall of the turntable, the cutter is slidably connected to the inner wall of the turntable through an elastic member, the motor is fixedly connected to the inner wall of the support block, the transmission gear is fixedly connected to the output end of the motor, the cylinder is fixedly connected to the inner wall of the workbench, and the guide plate is fixedly connected to the output end of the cylinder; the limiting device is arranged on the top of the workbench, and the grinding device is arranged on the surface of the limiting device. The supporting device is arranged on the inner wall of the workbench; the surface of the transmission gear is meshed with the surface of tooth one, the surface of the guide plate is slidably connected with the inner wall of the workbench, and the surface of the cutter is in contact with the inner wall of the guide plate. The cable is passed through the turntable for cutting. At this time, the motor starts and rotates, and the motor drives the transmission gear to rotate. The transmission gear drives tooth one to rotate. Tooth one drives the turntable to rotate on the support block, and the turntable drives the cutter to perform circular cutting of the cable. At the same time, the cylinder starts and drives the guide plate to move. The guide plate pushes multiple cutters toward the center through the inclined surface of the inner wall. At this time, multiple cutters rotate and gather together until the cable is cut. Through circular cutting, the cable cutting surface can be well prevented from deformation, thereby facilitating the subsequent connection between the two cables.

[0006] According to the above technical solution, the limit device includes a limit block, an elastic telescopic rod, a pressure plate, a rubber strip and an inclined plate, the limit block is fixedly connected to the top of the workbench, the elastic telescopic rod is slidably connected to the inner wall of the limit block, the pressure plate is fixedly connected to the bottom end of the elastic telescopic rod, the rubber strip is fixedly connected to the bottom of the pressure plate, the inclined block is fixedly connected to the top end of the elastic telescopic rod, and the inclined plate is fixedly connected to both sides of the guide plate; a spring is sleeved on the surface of the elastic telescopic rod, and the two ends of the spring are respectively in contact with the bottom of the inclined block and the top of the limit block. The surface of the inclined plate is in contact with the surface of the inclined block. When the cylinder drives the guide plate to move, the guide plate will also drive the inclined plate to move. The inclined plate will apply a horizontal thrust to the inclined block, but on the inclined surface where the inclined block and the inclined plate contact, the horizontal thrust will be converted into a downward push. Therefore, the inclined block will move downward and drive the elastic telescopic rod to move downward. The elastic telescopic rod will drive the pressure plate to move downward. The pressure plate will drive the rubber strip to move downward and press and fix the cable to be cut to prevent the cable from being displaced during the cutting process, which will cause position offset during the cutting process, thereby affecting the cutting quality.

[0007] According to the above technical scheme, the grinding device includes a fixed plate and a grinding block, the fixed plate is fixedly connected to the bottom of the inclined plate, and the grinding block is fixedly connected to the surface of the fixed plate; the grinding device also includes an elastic plate and a knocking block, the elastic plate is fixedly connected to the top of the pressure plate, and the knocking block is fixedly connected to the top of the elastic plate; the surface of the grinding block is in contact with the surface of the cutter, the knocking block is located on the left side of the fixed plate, the fixed plate is located on the left side of the turntable, an absorption device is arranged inside the fixed plate, the absorption device includes an elastic sealing sheet, a transmission plate, a baffle, an air column and an air outlet frame, the elastic sealing sheet is fixedly connected to the inner wall of the left side of the fixed plate, the transmission plate is fixedly connected to the right side of the elastic sealing sheet, the baffle is fixedly connected to the side of the transmission plate away from the elastic sealing sheet, and the air column is connected to the fixed plate On the left side, the air outlet frame is fixedly connected to the inner wall of the right side of the fixed plate. When each cutting is completed, the guide plate will drive the inclined plate to move when it is reset, and the inclined plate will drive the fixed plate to move, and the fixed plate will drive the grinding block to move, and the grinding block will move and contact the surface of the cutter. At this time, the motor is still in the starting state, and the turntable will still rotate and drive the cutter to rotate, so that the surface of the cutter can be polished to prevent the surface of the cutter from becoming dull due to long-term use and affecting the cutting effect. At the same time, when used next time, the guide plate will drive the inclined plate to move, and the inclined plate will drive the fixed plate to move, so that the fixed plate will collide with the knocking block on the elastic plate. At this time, the fixed plate will be knocked and vibrate, and the vibration will be transmitted to the grinding block, thereby causing the grinding block to vibrate, prompting debris on the surface of the grinding block to fall off, to prevent debris from remaining between the grinding block and the cutter during subsequent grinding, affecting the grinding effect.

[0008] According to the above technical scheme, the supporting device includes a supporting plate, tooth 2, a pinion and a tooth groove, the supporting plate is slidably connected to the inner wall of the workbench, the tooth 2 is fixedly connected to the lower surface of the supporting plate, the pinion is rotatably connected to the inner wall of the workbench, and the tooth groove is arranged on the surface of the output end of the cylinder; the supporting device also includes an airbag, an air pipe, an air outlet and an elastic brush plate, the airbag is installed on the inner wall of the workbench, the air pipe is connected to the left side of the airbag, the air outlet is arranged on the inner wall of the guide plate, and the elastic brush plate is fixedly connected to the inner wall of the guide plate; the bottom of the elastic brush plate is in contact with the surface of the supporting plate, the surface of the air pipe is slidably connected to the inner wall of the right side of the guide plate, the left side of the airbag is in contact with the right side of the guide plate, the surface of the pinion is meshed with the surface of tooth 2, and the surface of the pinion is meshed with the tooth groove The inner walls of the guide plate are meshed with each other, and the air bag is connected to the air outlet hole. When the cable passes through the turntable, the cable will move on the support plate, and the support plate can support the cable to facilitate its passing through the turntable. When the cylinder starts and drives the guide plate to move, the tooth groove opened on the surface of the cylinder output end will drive the small gear to rotate, and the small gear will drive the tooth 2 to move, and the tooth 2 will drive the support plate to move right, preventing the support plate from blocking the movement and cutting of the cutter. When the guide plate moves to the right and resets, the right side of the guide plate will contact and communicate with the air pipe. At this time, the guide plate will also squeeze the air bag, and the air bag will blow the gas into the guide plate through the air pipe and blow it out through the air outlet hole in the guide plate. The blown gas can blow away the cutting debris to prevent the debris from affecting the next cutting operation, and the elastic brush plate will scrape off the debris on the surface of the support plate when the support plate moves, to prevent the debris from affecting the placement of the cable.

[0012] The present invention enables the grinding block to grind the surface of the cutter through the coordinated operation of the fixed plate, the grinding block, the elastic plate and the knocking block, thereby preventing the surface of the cutter from becoming blunt due to long-term use and thus affecting the cutting effect. At the same time, when used next time, the fixed plate will collide with the knocking block on the elastic plate. At this time, the fixed plate will be struck and vibrate, and the vibration will be transmitted to the grinding block, thereby causing the grinding block to vibrate, causing debris on the surface of the grinding block to fall off, thereby preventing the debris from remaining between the grinding block and the cutter during subsequent grinding and affecting the grinding effect.

[0013] The present invention, through the coordinated operation among the support plate, tooth 2, pinion, tooth groove, air bag, air pipe, air outlet and elastic brush plate, the support plate can support the cable to facilitate its passing through the turntable; when the cylinder is started, the support plate will move right to prevent the support plate from blocking the movement and cutting of the cutter; when the guide plate moves right to reset, the right side of the guide plate will contact and connect with the air pipe, and the guide plate will also squeeze the air bag at this time, and the air bag will blow the gas into the guide plate through the air pipe and blow it out through the air outlet in the guide plate, and the blown gas can blow away the cut debris to prevent the debris from affecting the next cutting operation, and the elastic brush plate will scrape the debris on the surface of the support plate when the support plate moves to prevent the debris from affecting the placement of the cable.
