Description

Technical Field

[0001] The invention relates to the technical field of insulator forming and processing, in particular to a power porcelain insulator forming and processing device and a method thereof. Background Art

[0002] As an important component in the power industry, the molding and processing equipment of power porcelain insulators plays a vital role in the production process of insulators. Traditionally, the production of power porcelain insulators includes multiple links such as raw material preparation, clay making, molding, glazing, firing and assembly. In the molding stage, it mainly relies on mold pressing, spinning or wire knife forming to shape the carefully proportioned and processed porcelain clay into the basic shape of the insulator; with the continuous development of the power industry, the performance requirements for power porcelain insulators are also constantly improving, which requires molding and processing equipment to not only have high precision and high efficiency, but also be able to adapt to the production needs of insulators of different formulas and shapes. Therefore, the technical level of power porcelain insulator molding and processing equipment is also constantly improving to meet the needs of industry development.

[0003] In the prior art, there is a disc-shaped porcelain insulator blank repairing device with a function of collecting and processing residual materials into rod blanks, such as the publication number CN207509460U, which includes a frame and a working platform arranged on the frame, on which a rotatable main shaft and an intermittently rotating auxiliary shaft are relatively arranged, and a pressing plate capable of rotating and tightly pressing the blank is arranged on the top of the main shaft. While the blank repairing machine is working, the blank cuttings are recovered, thereby reducing the interference of the cuttings on the device and improving the working environment during the blank repairing; while the residual materials are collected, the residual materials can be extruded into rod-shaped blanks of different diameters and lengths, which can be directly used as the processing blanks of the insulators.

[0004] During the spinning process of the pressed blank structure, if a hole needs to be reserved in the center of the blank, a hollow pressed blank tool is often connected under the pressing plate. The tool presses down after the blank is rotated. At this time, excess blank will flow out from the side wall groove of the tool, and the excess blank needs to be manually removed, which increases the labor intensity and operation time. If the excess blank is not taken out in time, the forming effect of the insulator will be affected.

[0005] Therefore, the present invention proposes a method to solve the problem that the pressing tool used in the existing rotary forming equipment presses down after the blank is rotated, and the excess blank will flow out from the side wall groove of the tool, and these excess blanks need to be manually removed and easily affect the forming effect of the insulator.

The conveying assembly includes a rotating inner tube 34, a driving member and a spiral blade 36. The spiral blade 36 is movably installed on the inner side of the rotating inner tube 34. A rotating blank anti-falling assembly is provided directly below the spiral blade 36. The outer surface of the hollow outer cylinder 31 is fixedly connected to the end of the swing arm plate 16 away from the lifting seat 15. The inner surface of the hollow outer cylinder 31 is fixedly connected to the end of the swing arm plate 16 away from the lifting seat 15. The side surface is fixedly connected to the hollow inner tube 33, and the rotating inner tube 34 is rotatably installed on the inner side of the hollow inner tube 33. The rotating inner tube 34 is a hollow tube-shaped structure. A threaded convex strip 341 is fixedly installed on the inner wall of the rotating inner tube 34, and a discharge port 340 is opened on the upper inner wall of the rotating inner tube 34; a lifting assembly is provided at the upper end of the vertical plate 14, and the lifting assembly includes a lifting motor 141 fixedly installed on the upper end of the vertical plate 14, and a screw 142 is fixedly connected to the output shaft of the lifting motor 141.

[0043] In this embodiment, if Figure 4As shown, the entire longitudinal height of the central cone cutter 32 can be adjusted through the control of the lifting assembly to adapt to the repairing operation of the insulator blank without affecting the loading and unloading of the blank. Specifically, the lifting motor 141 is controlled to start, and the output shaft drives the screw 142 to rotate. Under the dual limiting effects of the thread adaptation and the vertical plate 14, the thread block 143 drives the lifting seat 15 to move in the vertical direction along the vertical plate 14. At this time, the swing arm plate 16 moves synchronously and drives the height adjustment of the central cone cutter 32; and through the side plate The setting of 151 provides structural support for the electric telescopic rod 152. When the electric telescopic rod 152 is driven, the piston rod at its output end drives the swing arm plate 16 to swing at different angles, so as to adjust the horizontal position of the central cone tool 32, ensure that the central cone tool 32 will not block the loading and unloading of the blank, and ensure that after the waste material in the inner cavity of the rotating inner tube 34 is full, the blank center trimming mechanism 3 is swung as a whole to the side of the rotating blank seat 11, so that the waste material is discharged through the discharge port 340; and the power porcelain insulator forming process The equipment combines the blank forming machine 1 with the waste blank conveyor 2 to trim the rotating blank and output the excess blank. When the center cone cutter 32 contacts the blank on the blank rotating seat 11, the center cone cutter 32 continues to press down, and at this time, the blank rotating seat 11 drives the blank to rotate. Under the action of rotation, the center of the blank is formed with a center hole by the center cone cutter 32, and the excess blank passes through the reserved groove of the center cone cutter 32 and enters the inner cavity of the center cone cutter 32 for storage. At this time, the waste squeezed into the center cone cutter 32 will be discharged from the bottom. The setting of the upward outflow and billet anti-falling assembly can ensure that the waste material flowing upward will not fall again, prevent the center collapse of the power porcelain insulator, and avoid secondary blockage of the outlet of the center cone tool 32; and through the setting of the quick-change assembly, the center cone tool 32 can be quickly replaced according to different insulator forming structures, which is highly practical and saves production costs; it should be noted that the billet rotating seat 11 and the billet trimming knife group 12 are both independently controlled to rotate by the driving structure, and the billet is trimmed by the rotating billet trimming knife group 12.

[0044] Embodiment 2, refer to the attached Figure 1-16On the basis of the first embodiment, in order to realize the storage and automatic output of the gushing material of the center cone cutter 32: the driving member includes a motor 35, the motor 35 is fixedly mounted on the upper surface of the swing arm plate 16, the output shaft of the motor 35 is fixedly connected with a connecting shaft 351, the outer surface of the connecting shaft 351 is fixedly mounted with an active bevel gear 1 352 and an active bevel gear 2 354, the active bevel gear 1 352 and the connecting shaft 351 are both centered on the connecting shaft 351 and are in opposite directions; the lower outer surface of the active bevel gear 1 352 is meshed and rotated with A driven bevel gear 1 353, the lower surface of which is fixedly connected to the upper surface of the rotating inner tube 34, and the central inner surface of the rotating inner tube 34 is movably connected to the upper outer surface of the spiral blade 36; a driven bevel gear 2 355 is meshed and rotated on the lower outer surface of the driving bevel gear 2 354, the central inner surface of which is fixedly connected to the upper outer surface of the spiral blade 36, and the upper outer surface of the spiral blade 36 is movably connected to a support plate 3551, and one end of the support plate 3551 is fixedly connected to the upper surface of the hollow outer tube 31;

[0045] In this embodiment, if Figure 4-Figure 8 As shown, when the waste material flowing upward from the bottom enters the bottom of the rotating inner tube 34, it is necessary to automatically remove the waste material. The specific operation is to control the motor 35 to drive so that its output shaft rotates and drives the connecting shaft 351 to rotate. At this time, the active bevel gear 1 352 and the active bevel gear 2 354 rotate synchronously, the active bevel gear 1 352 and the driven bevel gear 1 353 are adapted to mesh, and the active bevel gear 2 354 and the driven bevel gear 2 355 are adapted to mesh. Due to the relative position of the active bevel gear 1 352 and the active bevel gear 2 354, the active bevel gear 1 352 and the driven bevel gear 2 354 are adapted to mesh. Distribution, the driven bevel gear 353 drives the rotating inner tube 34 and the spiral blade 36 to rotate in different directions, and the threaded convex strips 341 arranged on the inner side of the rotating inner tube 34 rotate continuously, and the waste at the bottom of the rotating inner tube 34 is continuously transmitted.

[0047] In this embodiment, if Figure 5-Figure 7 As shown, an annular baffle 37 fixedly connected to the side wall of the hollow inner cylinder 33 is arranged directly below the rotating inner tube 34. Here, the connecting ring 370 and the annular baffle 37 are integrally formed. The annular design of the connecting ring 370 can avoid the cutting of the gushing waste caused by the sharp part, and as shown in FIG. Fig. 9 As shown, when the waste flows out from bottom to top, it will push the bottom of the petal-shaped gathering arc plate 371. At this time, the multiple sets of petal-shaped gathering arc plates 371 are changed from a gathered state to an open state. When the waste falls into the inner cavity of the rotating inner tube 34, the threaded convex strips 341 immediately output it upward. At the same time, the petal-shaped gathering arc plates 371 will be gathered again to close the center groove of the connecting ring 370 to prevent the waste from falling and causing the collapse of the central reserved hole of the formed blank. It should be noted that the lower end of the petal-shaped gathering arc plate 371 is connected to the connecting block 3711 and is compatible with the card slot 3700, so that a single set of petal-shaped gathering arc plates 371 can be quickly assembled, and the setting of the spring 3713 facilitates the petal-shaped gathering arc plate 371 to make the gathering and opening actions more efficient.

[0048] Embodiment 4, refer to the attached Figure 1-16On the basis of the third embodiment, in order to realize the support and protection of the overall structure of the annular baffle 37, the present embodiment adds a protective member: a protective member is arranged at the lower end of the annular baffle 37, and the protective member includes a supporting rib 372 and an inclined baffle 3721, the supporting rib 372 is fixedly mounted on the lower inner wall of the hollow inner cylinder 33, the outer surface of the supporting rib 372 is fixedly connected to the inclined baffle 3721, and the upper end of the inclined baffle 3721 is fixedly connected to the lower surface of the annular baffle 37; an annular cavity is arranged between the inner surface of the hollow outer cylinder 31 and the outer surface of the hollow inner cylinder 33, the upper end of the annular cavity is connected through with a water injection pipe 310 extending to the top of the hollow outer cylinder 31, the lower end of the hollow inner cylinder 33 is arranged as a tapered structure extending downward, and water spray holes 330 are evenly opened on the inner wall of the tapered structure, and the water spray holes 330 are communicated with the annular cavity;

The inclined baffle 3721 here is located on the outside of the water spray hole 330, which can block the water source sprayed out of the water spray hole 330 to prevent the water source from spraying directly to the center position of the central conical tool 32 to increase the humidification of the extruded excess blank. Instead, through the blocking reflection of the inclined baffle 3721, it is ensured that the sprayed water rebounds and flows along the lower inner wall of the hollow inner cylinder 33 to the contact surface between the rotating blank and the central conical tool 32. In this way, the blank can be rotated while water is injected, which can avoid cracking of the rotating blank and reduce the resistance between the central conical tool 32 and the blank, thereby reducing the wear of the central conical tool 32 and the damage of the blank, achieving lubrication of the blank and the central conical tool 32, and reducing friction. In this way, the quality and efficiency of the forming of power porcelain insulators are further improved, and there is no need for manual water replenishment. The degree of automation is high, which reduces the labor burden of the staff.

[0051] In this embodiment, if Figure 5 and Figure 9-11 As shown, when the center cone tool 32 needs to be replaced to adapt to different formed blanks, the operator rotates the force-bearing handle 381 after finishing spinning the blank or before starting spinning the blank, so that the pressure strip 382 moves to both sides until the pressure strip 382 is parallel to the fixed block 38. At this time, the swing pressure plate 384 is disengaged from the extrusion restriction of the pressure strip 382, ​​and the embedding block 3841 rotates outward. At the same time, the embedding block 3841 moves outward synchronously and disengages from the embedding groove 3210.

[0053] Step 1: Stabilize the complete power porcelain insulator forming blank on the upper end of the rotating blank seat 11, keep the blank column upright, then connect the external power supply and start the whole equipment;

[0054] Step 2: respectively control the blank rotating seat 11 and the blank trimming knife group 12 to rotate, and during the blank trimming process of the blank trimming knife group 12, the center cone cutter 32 is gradually pressed down to press a blank hole in the center of the blank;

[0055] Step 3: The excess blanks are stored in the inner cavity of the center cone cutter 32 through the reserved groove of the center cone cutter 32. At this time, the waste materials squeezed into the center cone cutter 32 will flow out from the bottom to the top. The setting of the blank anti-falling assembly prevents the waste materials flowing upward from falling, thereby preventing the center of the power porcelain insulator from collapsing.

[0056] Step 4: The rotating inner tube 34 and the spiral blade 36 are driven by the driving member to rotate in different directions, and the waste at the bottom of the rotating inner tube 34 is continuously transferred upward. The cavity of the rotating inner tube 34 can carry a certain volume of waste;

[0057] Step 5. After a group of blanks are turned and trimmed, the operator lifts the center trimming mechanism 3 of the blank and deflects it to one side of the turning seat 11. At this time, the rotating inner tube 34 and the spiral blade 36 continue to work to discharge the waste and drop it on the waste blank conveyor 2 for transportation, and the formed power porcelain insulators are taken out and replaced with new blank columns, and the above operations are repeated.

[0058] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
