Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of roll machinery, in particular to a device for scraping residual oil stains and grinding fluid on the roll surface after the roll surface of an electric discharge texturing machine and a CNC roll grinder is processed. Background Art
[0002] The electric discharge texturing machine is a multi-electrode scanning texturing station. The small-flow electrolyte (20L) can quickly fill and discharge to reduce the pre-texturing preparation time. Graphite additives are added to the insulating oil to improve the conductivity of the electrode, greatly improving the texturing efficiency. The electrode has a simple design and wide material adaptability. Since graphite powder additives are added to the electrolyte, there are residues of electrolyte and graphite powder on the roll surface after texturing. There is a safety fence installed around the equipment, and the safety door uses a safety interlock switch to effectively separate people and machines. During the normal texturing process of the equipment, personnel cannot enter the equipment operation area. Once the safety door is opened, the equipment cannot operate, nor can the roll be rotated. The initial fit between the texturing station and the roll surface is poor during the seal replacement, which is likely to cause electrolyte leakage. To reduce the electrolyte leakage during the roll texturing process and to clean the roll surface when the safety door is not opened, an automatic water scraping device is designed to enable water scraping operations during the roll texturing process and reduce the residues of electrolyte and graphite powder on the roll surface.

[0028] The following further describes the utility model in conjunction with the drawings and embodiments:
[0029] Figures 1 to 10 The automatic roll surface water scraping device includes a first bracket 1, a wiper 2, a wiper bracket 4, a second bracket 5, a ball screw 6, a driving motor 7, a screw base 8, and a moving nut seat 9.
[0030] Such as Figure 1 AndFigure 2 As shown, the lead screw base 8 is installed on the spaced first bracket 1 and second bracket 5. A moving nut seat 9 is provided on the lead screw base 8. Bearing seats 10 are installed at both ends of the lead screw base 8. Both ends of the ball screw 6 are installed in the bearing seats 10. The ball screw 6 passes through the moving nut seat 9. One end of the ball screw 6 is connected to the driving motor 7 through a coupling; the ball screw 6, the moving nut seat 9 and the driving motor 7 are installed between the bearing seats 10 at both ends of the lead screw base 8 to form a transmission device that can automatically move forward and backward. One end of the wiper blade bracket 4 is connected to the moving nut seat 9, and the other end is connected to the wiper blade 2.
[0031] As Figure 3 and Figure 4 shown, the first bracket 1 and the second bracket 5 have the same structure and are made by cutting 3mm thick 202 stainless steel plates, bending both ends, drilling holes at the bottom, and welding. When in use, they are installed on the deburring station bracket of the electric discharge texturing machine. Corresponding to different positions of the deburring station bracket, the first bracket 1 and the second bracket 5 have the same length and width, but their heights are not necessarily equal. In this embodiment, the length of the first bracket 1 and the second bracket is 350mm, the width is 50mm, the height of the first bracket 1 is 105mm, and the height of the second bracket is 87mm.
[0032] As Figure 5 and Figure 6 shown, the wiper blade bracket 4 includes a straight plate and bending parts and round rod parts at both ends of the straight plate; in this embodiment, the straight plate and the bending parts are cut and bent from 3mm thick 202 stainless steel plates; the straight plate is 150mm long and 45mm wide; the bending parts are 57mm long and 45mm wide; the round rod part of the round rod is 125mm long and 22mm in diameter; mounting holes are drilled on the bending parts, and the dimensions of the mounting holes are shown in Figure 6 .
[0033] The bending part of the wiper blade bracket 4 is installed on the moving nut seat 9 through screws, and the round rod part of the wiper blade bracket 4 is fixedly connected to the wiper blade 2.
[0034] As Figure 7 and Figure 8As shown in the figure, the wiper blade 2 includes a scraping part and a handle part; the scraping part is 250 mm long, 25 mm wide, and 10 mm thick, and is made of 202 stainless steel; the handle part is a cylinder, and there is a threaded hole on the cylinder of the handle part, and a wiper blade adjustment and fixing screw 3 is arranged in the threaded hole; the outer diameter of the cylinder of the handle part is 28 mm, and the inner diameter matches the diameter of the round rod part of the wiper blade support 4, which is 22 mm. During installation, the round rod part of the wiper blade support 4 is inserted into the cylinder of the handle part of the wiper blade 2, and the scraping surface angle of the scraping part is adjusted to be inclined 15 degrees from the horizontal plane. Then, the wiper blade adjustment and fixing screw 3 is tightened so that when the scraping surface fits the roller surface, oil, water and other impurities on the roller surface will automatically flow to the oil receiving basin on the support and automatically flow back to the oil return tank. The scraping part of the wiper blade 2 is provided with an ethylene propylene diene monomer (EPDM) foam board with a thickness of 15 mm or a sealed installation foam rubber.
[0035] As Figure 9 and Figure 10 shown, the ball screw 6 installed on the screw base 8 is 1000 mm long, and the materials are stainless steel and aluminum alloy. The screw accuracy is 0.3 mm, the maximum load is 20 kg, and the maximum speed is 0 mm / s - 100 mm / s. The dimensions of the screw base 8 and others are detailed in Figure 10 .
[0036] The ball screw 6, the moving nut seat 9 and the drive motor 7 are installed between the bearing seats 10 at both ends of the screw base 8 to form a transmission device that can automatically move forward and backward. Such a transmission device can be composed of existing complete sets of products of each component, and can be used as a mechanical device to provide linear motion. The movement of the wiper blade 2 is parallel in and parallel out; the drive motor 7 is a stepper motor, and a two-phase stepper motor with a torque of 1.3 Nm and a step angle of 1.8° is used as the power source. Considering that the rolls to be textured have different types and sizes, and it is impossible to judge the appropriate position of the wiper blade during wiping, a jogging method is adopted, and the operator judges the wiping position and issues the control command. The stepper motor controller is set to single speed and jogging mode. The stepper motor is set to 10 microsteps in control, and the stepper motor rotates one circle when 2000 pulses are sent, that is, the stepper motor rotates 0.18° when one pulse is sent.
[0037] The working process of the whole system is as follows: The operator observes the surface of the wiper blade to the roll, and presses the button of the hand control box to make the wiper blade move forward. After receiving the 24V control signal from the hand control box, the controller sends a direction level to the driver through DIR, and sends a pulse control command to the driver through PUL to control the rotation of the stepper motor. When seeing that the wiper blade reaches the appropriate position, release the button to stop the output of the control level. The frequency of the pulses output by the controller is adjusted by the analog quantity given by the speed regulating potentiometer to achieve the purpose of controlling the motor speed.
