Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing and manufacturing equipment, and in particular relates to a glass fiber bushing frame full-automatic shaping equipment and shaping method. Background Art

[0002] The glass fiber leak plate frame (hereinafter referred to as the leak plate frame) is a special-shaped metal frame cast by high-temperature resistant alloy. It is the base for inlaying platinum leak plates and fixing cooler frames. The manufacturing accuracy of the leak plate frame directly affects the installation position of the platinum leak plates and cooler frames. When the flatness of the leak plate frame is not high, the fixed cooler will cause a large position deviation between the cooling fin and the surface of the platinum leak plate, uneven leak plate surface temperature, uneven cooling of the wire roots, poor operation stability, and deterioration of fiber diameter uniformity, affecting the strength of glass fiber and other performance indicators. Therefore, the processing accuracy of the leak plate frame has a great influence on the stability of the wire drawing operation and the quality of the glass fiber.

[0003] In actual production, the leak plate frame and the platinum leak plate are installed and used at the same time. They need to be hoisted and fixed on the top of the high-temperature (1400℃) wire drawing channel for a long time. Affected by the high-temperature radiant heat and the deadweight of the platinum leak plate and the cooler, high-temperature stress creep will occur, causing large deformation, which will have a certain impact on the recycling and wire drawing process of the leak plate frame. Therefore, the leak plate frame must be reshaped before it can be used again.

[0004] In the prior art, the shaping operation of the leak plate frame still adopts the manual repair method. The leak plate frame of the production line is replaced frequently and in large quantities. Relying on manual shaping, due to the difficulty in controlling the strength, the shaping deviation is large, which seriously affects the quality of use. In addition, during the manual operation, the long-term fixed posture and long-term bowing of the head can easily lead to cervical pain, low work efficiency, and high labor intensity.

[0059] The following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application: Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0060] It should be noted that the following detailed descriptions are exemplary and are intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0061] Example 1: A fully automatic shaping device for a fiberglass bushing frame

[0062] like Figure 1 , Figure 2 As shown, it includes: a main frame workbench 1, and an electrical control box 2, a pneumatic control box 3, a control panel 4, a lifting mechanism 5, a pushing mechanism 6, a positioning mechanism 7, a downward pressure shaping mechanism 8, and a side pressure shaping mechanism 9 arranged on the main frame workbench 1.

[0063] like Figure 1 to Figure 7 As shown, the upper part of the main frame workbench 1 is equipped with a first protective cover 1-1, a second protective cover 1-4, and a first connecting base 1-3 and a second connecting base 1-5 for fixing the foundation of the mechanical parts; the bottom of the first protective cover 1-1 is provided with an inlet and outlet 1-2;

[0064] The electrical control box 2 is arranged on the left side of the lower part of the main frame workbench 1, and the electrical control components and the actuator motor driver are installed in the electrical control box;

[0065] The pneumatic control box 3 is arranged on the right side of the lower part of the main frame workbench 1, and pneumatic control components are installed inside it;

[0066] The control panel 4 includes operation control buttons and a servo controller, and is installed on the first protective cover 1-1 on one side of the electrical control box 2; the second protective cover 1-4 is used to set the downward pressure shaping mechanism 8;

[0067] like Figure 7 As shown, the lifting mechanism 5 includes two metal rib plates 5-1, and the two metal rib plates 5-1 are symmetrically distributed in the equipment shaping area along the longitudinal axis of the equipment. The telescopic rods of the thin cylinder 5-2 are respectively connected below the two ends of each metal rib plate 5-1. The thin cylinder 5-2 is installed under the main frame workbench. The four thin cylinders 5-2 move synchronously, and the metal rib plate 5-1 is driven by the telescopic rod of the thin cylinder 5-2 to perform lifting and lowering movements perpendicular to the main frame workbench. By adopting the above technical solution, the lifting mechanism serves to provide a smooth reference plane for the leak plate frame when entering and exiting the equipment. As a typical embodiment, after the metal rib plate 5-1 is lifted, its upper surface is flush with the lower surface of the feed inlet and outlet 1-2, and after the metal rib plate 5-1 is lowered, it is embedded in the positioning mechanism 7; specifically, its upper surface is flush with the upper surface of the lower frame of the positioning mechanism frame 7-1.

[0068] like Figure 3As shown, the pushing mechanism 6 includes a double-acting cylinder 6-1, two pushing mechanism slider guide rails 6-2, two 90-degree lifting and rotating cylinders 6-3, an L-shaped positioning block 6-4, a piston rod connecting plate 6-5, and a stroke limiter 6-6. The tops of the 90-degree lifting and rotating cylinders 6-3 are respectively connected to rotating arms 6-7. The double-acting cylinder 6-1 is arranged along the longitudinal axis of the equipment. The tail end of the double-acting cylinder 6-1 is fixedly mounted on the second connecting base 1-5 on the surface of the main frame workbench 1. The piston rod connecting plate 6-5 is installed on the end of the front piston rod of the double-acting cylinder 6-1. Slide blocks are installed on both sides of the piston rod connecting plate 6-5. The slider guide rails 6-2 of the pushing mechanism matched with the slider are installed on the base surface of the main frame workbench 1 and parallel to the longitudinal axis of the equipment. Two 90-degree lifting and rotating cylinders 6-3 (rotating in opposite directions) are symmetrically installed above the front piston rod connecting plate 6-5 of the double-acting cylinder 6-1. An L-shaped positioning block 6-4 is fixed on the front plane of the piston rod connecting plate 6-5. A travel limiter 6-6 is arranged at the front end of the L-shaped positioning block 6-4. As a typical embodiment, Fig.10 As shown, when the leak plate frame is pushed forward, the front end of the leak plate frame is located between the rotating arm 6-7 and the L-shaped positioning block 6-4 at the top of the 90-degree lifting and rotating cylinder 6-3, and the two 90-degree lifting and rotating cylinders 6-3 rotate and rise in opposite directions at the same time, and the rotating arm 6-7 turns from horizontal to vertical, and the front end of the rotating arm 6-7 supports the inner wall of the wide side of the front end of the leak plate frame. Under the action of the extension movement of the piston rod of the double-acting cylinder 6-1, the two 90-degree lifting and rotating cylinders 6-3 play a pushing role. When the plate frame is pushed out, the L-shaped positioning block 6-4 presses against the outer wall of the wide side of the front end of the plate frame. Under the action of the piston rod retraction of the double-acting cylinder 6-1, the L-shaped positioning block 6-4 plays a pushing role. At the same time, the two 90-degree lifting angle cylinders 6-3 rotate and descend towards each other. At this time, the position of the rotating arm 6-7 changes from longitudinal to transverse, lying between the two metal ribs 5-1 of the jacking mechanism, and the upper plane of the rotating arm 6-7 is lower than the upper plane of the metal ribs 5-1, providing conditions for the plate frame to smoothly enter and exit with the two metal ribs 5-1 of the jacking mechanism as a slide. By adopting the above technical solution, the pushing mechanism is used to send or push the plate frame from the equipment inlet and outlet 1-2.

[0069] like Figure 4As shown, the positioning mechanism 7 has two groups, front and rear, which are arranged along the longitudinal axis of the equipment. Each group of positioning devices includes a positioning mechanism frame 7-1, a connecting rod positioning block 7-2, a three-axis cylinder 7-3, a positioning mechanism servo motor 7-4, a bidirectional ball screw 7-5, a positioning mechanism slider guide 7-6, a connecting rod 7-7, a bidirectional ball screw 7-5, a positioning mechanism slider guide 7-6, and a servo motor 7-4 to form an electric slide module. The positioning mechanism frame 7-1 is a flat frame structure designed according to the maximum passing width dimension of the leak plate frame, and a travel limiter is installed at the end of the positioning device 7-1 frame; the internal height of the positioning mechanism frame 7-1 is not less than the height of the equipment inlet and outlet 1-2, and the top rod of the positioning mechanism frame is not higher than the upper edge of the equipment inlet and outlet 1-2, and the height of the bottom rod of the positioning mechanism frame is not higher than the lower edge of the equipment inlet and outlet 1-2; a slider of a bidirectional ball screw 7-5 is installed at the bottom of the positioning mechanism frame 7-1, and a positioning mechanism slider guide 7-6 matched with the bidirectional ball screw 7-5 is installed on the base surface of the main frame workbench 1, and the front end of the bidirectional ball screw 7-5 is connected to the positioning mechanism servo motor 7-4, and the positioning mechanism servo motor 7-4 is installed on the base surface of the workbench 1 through the motor base. As a typical embodiment, Fig.11 , Fig.12 As shown, the connecting rod positioning block 7-2 and the connecting member 7-7 are connected by hinges to form a connecting rod transmission member, which is connected to the telescopic rod of the three-axis cylinder 7-3 by a connecting plate hinge to form a planar three-link mechanism. The connecting rod positioning block 7-2 is used as a fixed rod, one end of which is fixedly hinged to the positioning mechanism frame 7-1 through a hinge, and the other end is hinged to the connecting rod 7-7. The connecting rod 7-7 is hinged to the telescopic rod connecting plate of the three-axis cylinder 7-3. When the telescopic rod of the three-axis cylinder 7-3 is extended, the connecting rod 7-7 is pushed to move downward, and the connecting rod 7-7 pushes the connecting rod positioning block 7-2 to make a downward arc movement with the fixed hinge point as the axis, so that the connecting rod positioning block 7-2 is supported outward on both sides, realizing the downward pressing positioning function of the connecting rod positioning block 7-2 on the leak plate frame. When the telescopic rod of the three-axis cylinder 7-3 is retracted, it drives the connecting rod 7-7 to move upward, and the connecting rod 7-7 drives the connecting rod positioning block 7-2 to move upward in an arc with the fixed hinge point as the center of the circle, lifts the connecting rod positioning block 7-2, releases the leak plate frame, and retracts it to the upper space of the positioning mechanism frame 7-1. By adopting the above technical solution, after the operator sets the program according to the length of the leak plate on the control panel, the positioning mechanism servo motor 7-4 executes the program instructions to drive the two groups of connecting rod positioning blocks 7-2 together with the positioning mechanism frame 7-1 to move toward each other along the longitudinal axis direction, reaching the edges of both ends of the leak plate frame, and the connecting rod positioning block 7-2 is pushed by the three-axis cylinder 7-3 to support the inner wall of the leak plate frame 10 to both sides, mechanically pressurizes and fixes the leak plate frame 10, and improves the positioning accuracy of the leak plate frame 10 in the center of the equipment shaping area.

[0070] like Figure 4As shown, the metal rib plate 5-1 of the lifting mechanism 5 spans across the two sides of the two positioning mechanism frames 7-1 along the longitudinal axis direction. The bushing frame 10 is placed on the metal rib plate 5-1.

[0071] The lower frame of the positioning mechanism frame 7-1 is provided with a groove for accommodating the metal rib plate 5-1.

[0072] The range of the positioning mechanism 7 is the equipment shaping area.

[0073] like Figure 5 , Fig.15 As shown, the downward pressure shaping mechanism 8 includes a downward pressure servo electric cylinder 8-1, a guide sleeve 8-2, a guide column 8-3, a downward pressure shaping mold 8-4, a frame fixed base 8-5, and a self-resetting linear displacement sensor 8-6. The downward pressure shaping mechanism is arranged just above the shaping area of ​​the equipment and is fixedly connected to the second protective cover 1-4. The servo electric cylinder 8-1 is installed on the frame fixed base 8-5. The telescopic rod of the servo electric cylinder 8-1 passes through the circular hole of the frame fixed base and is connected and fixed to the downward pressure shaping mold 8-4. The lower surface of the downward pressure shaping mold 8-4 is set to an arc surface. Self-resetting linear displacement sensors 8-6 are installed on both sides and the middle position of the downward pressure shaping mold 8-4. Guide sleeves 8-2 are installed below the four corners of the frame fixed base 8-5, and the guide columns 8-3 matched therewith are installed on the downward pressure shaping mold 8-4. By adopting the above technical scheme, when the downward pressure shaping mechanism 8 performs shaping of the upper surface of the leak plate frame, the downward pressure servo electric cylinder 8-1 pushes the downward pressure shaping mold 8-4 to move vertically downward, and the guide sleeve 8-2 and the guide column 8-3 ensure the movement stability of the downward pressure shaping mold 8-4. The self-resetting linear displacement sensor 8-6 installed on the downward pressure mold 8-4 first contacts the upper surface of the leak plate frame and measures the distance data. The self-resetting linear displacement sensor 8-6 outputs an analog command signal to the controller. The controller judges the downward pressure shaping distance through the logical values ​​set by the program, and outputs a command to the downward pressure servo electric cylinder 8-1. The servo electric cylinder uses the large thrust and high-precision motion control characteristics to push the downward pressure shaping mold to apply mechanical pressure to the upper surface of the leak plate frame to produce reverse deformation and achieve the purpose of high-precision shaping.

[0074] like Figure 6 , Fig.14As shown, there are two groups of side pressure shaping mechanisms 9, which are arranged on the transverse axis and symmetrically installed on both sides of the shaping area along the longitudinal axis. Each group of side pressure shaping mechanisms includes: side pressure servo electric cylinder 9-1, side pressure slider guide rail 9-2, side pressure shaping mold 9-3, and self-resetting linear displacement sensor 9-4. The side pressure servo electric cylinder 9-1 is fixed by the first connecting base 1-3 of the component arranged on the main frame workbench. The push rod of the side pressure servo electric cylinder 9-1 is connected and installed with the rear end of the side pressure shaping mold 9-3. The front end surface of the side pressure shaping mold 9-3 is arranged to be an arc surface. Self-resetting linear displacement sensors 9-4 are installed on both sides and the middle position of the upper surface of the side pressure shaping mold 9-3. The side pressure slider is installed below the side pressure shaping mold 9-3, and the side pressure slider guide rail 9-2 matched therewith is arranged and installed on the base surface 1 of the frame workbench. By adopting the above technical scheme, when the two groups of side pressure shaping mechanisms 9 perform surface shaping on both sides of the long side of the leak plate frame, the side pressure servo electric cylinder 9-1 pushes the side pressure shaping mold 9-3 to move in the direction of the long side of the leak plate frame, and the self-resetting linear displacement sensor 9-4 installed on the side pressure shaping mold 9-3 first contacts the side surface of the long side of the leak plate frame and measures the distance data. The self-resetting linear displacement sensor 9-4 outputs an analog command signal to the controller, and the controller judges the side pressure shaping distance through the logical values ​​set by the program, and outputs a command to the side pressure servo electric cylinder 9-11. By utilizing the large thrust and high-precision motion control characteristics of the servo electric cylinder, the side pressure shaping mold is pushed to apply mechanical pressure to the side surface of the long side of the leak plate frame to generate reverse deformation and achieve the purpose of high-precision shaping.

[0075] like Fig.14 , 15 As shown, the arc surface setting principle of the shaping die of the side pressure shaping mechanism 9 and the downward pressure shaping mechanism 8 is as follows: Fig.13 Comparing the leak plate frame before and after deformation, the Z-shaped cross-sectional structure of the long side of the leak plate frame makes the deformation direction regular, that is, the longitudinal bending of the overall structure is always convex to both sides and bulge upward, and the shaping surfaces of the shaping molds 8-4 and 9-3 are set with convex arc surfaces according to the bending amplitude of the upper and side surfaces of the long sides of the leak plate frame.

[0076] The control system adopts a four-axis servo controller; further, it also includes a four-axis servo controller, a thin cylinder 5-2 of the jacking mechanism 5, a limiter of the pushing mechanism 6, a 90-degree lifting angle cylinder 6-3, a double-acting cylinder 6-1, a limiter of the positioning device 7, a three-axis cylinder 7-3, a positioning mechanism servo motor 7-4, a downward pressure servo electric cylinder 8-1, a self-resetting linear displacement sensor of the downward pressure shaping mold, a lateral servo electric cylinder 9-1, and a self-resetting linear displacement sensor of the lateral pressure shaping mold 9-3.

[0077] Embodiment 2, a method for shaping a glass fiber bushing frame

[0078] like Fig.16 The present invention shown in the figure has the following implementation principles: the power supply of the electrical control box 2 is turned on, the equipment is powered on, the servo control system executes the program of starting up and returning to the mechanical origin, and the operator writes program instructions or selects a program through the control panel 4;

[0079] Press the start button on the control panel 4, the program starts, and the positioning mechanism 7 executes the program instructions;

[0080] The pneumatic control box 3 controls the lifting mechanism 5 to move and rise, and the program enters the standby state;

[0081] The operator pushes the bushing frame to be shaped from the inlet and outlet 1-2, and triggers the L-shaped positioning block 6-4 on the pushing mechanism 6, and the front end travel limiter 6-6 triggers the signal, and the program executes the next action instruction;

[0082] The guide rods of the two 90-degree lifting and lowering cylinders 6-3 rotate relative to each other and rise, and the rotating arm 6-7 fixes the leak plate frame. At the same time, the guide rod of the double-acting cylinder 6-1 is pushed out to further push the leak plate frame into the equipment shaping area. During the pushing process, when the L-shaped positioning block 6-4 touches the mechanical limiter installed at the end of the positioning device 7-1 frame of the rear group of the positioning mechanism, the pushing stop signal is triggered, and the program executes the next action instruction;

[0083] The metal rib plate 5-1 of the lifting mechanism moves downward and falls into the groove provided in the lower frame of the positioning mechanism frame 7-1;

[0084] At this time, the wide side of the plate frame falls on the plane inside the positioning mechanism frame, the program action instruction is delayed for 2 seconds, and the program executes the next action instruction: the three-axis cylinder 7-3 pushes the main push rod of the connecting rod positioning block 7-2 to descend, and the positioning block 7-2 is supported outward along the inner wall of the plate frame to complete the mechanical pressurization and fixation of the plate frame. After the program delays for 2 seconds, the program executes the next action instruction;

[0085] The downward pressure shaping mechanism 8 is actuated, and the telescopic rod of the downward pressure servo electric cylinder 8-1 pushes the downward pressure shaping die 8-4 to move downward. When the self-resetting linear displacement sensor installed on the downward pressure shaping die contacts the upper surface of the leak plate frame, it is determined through distance detection whether shaping is required. If shaping is required, the program executes the next action instruction: the downward pressure shaping die 8-4 continues to move downward vertically and presses down to apply pressure to the upper surface of the leak plate to produce reverse deformation. If shaping is not required, the program executes the next action instruction;

[0086] The left and right side pressure shaping mechanisms 9 are in motion, and the telescopic rod of the lateral servo electric cylinder 9-1 pushes the side pressure mold 9-3 to move sideways. When the self-resetting linear displacement sensors installed on the left and right side pressure molds contact the side surface of the leak plate frame, the distance detection is used to determine whether the two sides of the leak plate frame need to be shaped. If shaping is required, the program executes the next action instruction: the side pressure shaping mold 9-3 continues to push forward and applies pressure to the side surface of the leak plate to produce reverse deformation. If shaping is not required, the program executes the next action instruction.

[0087] Each shaping mechanism executes the program action and returns to the program zero point. The leak plate frame is released from pressure, and each deformation surface rebounds and deforms to form a plane. The program executes the next action instruction: the positioning mechanism 7 is actuated, the three-axis cylinder 7-3 drives the connecting rod positioning block 7-2 to rise, the positioning block is retracted, and the program executes the next action instruction;

[0088] The lifting mechanism 5 executes the program action to lift and hold up the leak plate frame, and the program executes the next action instruction: the pushing mechanism 6 pushes the leak plate frame out of the shaping area, the operator takes out the leak plate frame, and the program stands by. At this point, the shaping of the leak plate frame is completed.

[0089] Embodiment 3, a method for shaping a glass fiber bushing frame

[0090] The principle of straightness determination and detection is as follows: Based on the data analysis of the deformation of various models and sizes of the leak plate frame, the following conclusions are drawn: 1. The deformation of the same model of leak plate frame is relatively consistent; 2. The longer the leak plate frame is used, the greater the plastic deformation caused by the high temperature radiation heat and external force (leak plate deadweight); 3. Fig.13 As shown, the Z-shaped cross-sectional structure of the long side of the leaky plate frame makes the deformation direction regular, and the long side always bulges outwards and upwards on both sides;

[0091] According to the above conclusions, the shaping of the leak plate frame is mainly aimed at repairing the straightness of the long side to meet the dimensional tolerance requirements. In order to improve the precise operation of the equipment shaping and the straightness detection, the technical solution of the present invention is respectively installed at both ends and the center of the lower die and the two sets of side dies with self-resetting linear displacement sensors using the three-point straight line measurement method: that is, the controller program sets the relative distance values ​​measured by the three sensors to meet the requirements, the control signal forms a path, and the program determines it as a straight line. In implementation, the displacement sensors installed at three positions on the same die move with the die, the sensor guide rod contacts the surface of the leak plate frame, measures the distance data, and outputs the signal to the control program through the analog instruction. The control program detects the straightness through the set logical value, and then determines whether shaping is required.
