Description

Technical Field

[0001] This invention relates to the field of insulator blanking technology, specifically to an insulator blanking forming apparatus and forming method. Background Technology

[0002] In the process of making ceramic insulators, the clay needs to be shaped first. After the clay is shaped, it needs to be air-dried before it is fired. In order to ensure that the ceramic insulator has a perfect shape after firing, the clay is usually shaped during the clay shaping process.

[0003] Chinese patent CN207021053U discloses a ceramic insulator turning device, including a frame, a table, and a rotating shaft. The frame is equipped with a rotary motor, and the top surface of the rotating shaft is equipped with a clamping plate. A side blade mounting bracket is located on the left side of the clamping plate, and a side blade mounting plate is mounted on the side blade mounting bracket. The side blade mounting plate is equipped with a side blade slide rail, and the side blade slide rail is equipped with a side blade slide seat. A side blade body is located on the right side of the side blade slide seat. This patent uses the side blade body to externally shape the rotating clay blank, and uses a lifting and horizontally movable upper rotating blade to shape the top and inner wall of the clay blank. Both the side blade body and the upper rotating blade are automatically controlled, resulting in precise shaping of the clay blank and a perfect shape after firing.

[0004] The aforementioned patented spinning equipment only has one type of internal spinning tool in actual use, which makes it impossible to adjust the tool as needed during spinning, resulting in poor adaptability of the entire equipment. Furthermore, it cannot simultaneously spin the insulator blank from both inside and outside, affecting spinning efficiency. Therefore, it does not meet the existing requirements. In response, we propose an insulator spinning forming device and its forming method. Summary of the Invention

[0005] The purpose of this invention is to provide an insulator blank forming device and its forming method. By allowing selection of cutting tools to process the inner wall of the insulator blank as needed, the adaptability of the entire processing device is improved, enabling the processing of various insulators. The left and right clamping rings clamp and fix the bottom end of the insulator blank, ensuring the stability of the insulator blank during processing and preventing dislocation. Adjusting the curvature of the inner arc-shaped blade effectively adjusts the inner wall curvature as needed, increasing processing accuracy. It also effectively improves the adjustment of the distance between the outer concave blade and the inner arc-shaped blade, and the outer concave blade and the inner arc-shaped blade work together to simultaneously rotate the insulator inside and out, improving rotation efficiency. Simultaneous extension and retraction can drive the mounting base to rotate, improving driving convenience and flexibility. Different blades in the inner rotating assembly can be selected for processing as needed, improving adjustment convenience and allowing for arbitrary adjustments as required, increasing the adaptability of the entire device, improving processing accuracy, and solving the problems mentioned in the background art.

[0010] Preferably, the vertical blade is fixed inside the mounting plate, the mounting plate is connected to the docking plate through a bearing, and a motor connected to the mounting plate is mounted on the docking plate. The rear of the docking plate is connected to the mounting base.

[0011] Preferably, a cone-shaped body is provided below the mounting base, and a slanted blade is installed on the outer end face of the cone-shaped body.

[0012] Preferably, the external rotation device includes an external bracket, an external concave blade, a connecting rod, and an adjusting bracket. The external concave blade is installed at the inner end of the external bracket, and the rear of the external bracket is connected to the adjusting bracket via a shaft-connected motor. An arc-shaped blade plate is connected to the upper end of the external concave blade, and the arc-shaped blade plate and the blade at the upper end of the inner arc-shaped blade are staggered.

[0013] Preferably, the adjustment assembly includes an upper connecting screw, a limiting rod, an upper connecting plate, and a fixing plate. The upper connecting plate is fixed on the adjustment bracket. The upper end of the adjustment bracket is sleeved on the upper connecting screw and the limiting rod through the upper connecting plate. One end of the upper connecting screw and the limiting rod is mounted on the fixing plate. One end of the fixing plate is fixed on the outer end of the mounting base. One end of the upper connecting screw is connected to a motor on the fixing plate.

[0014] Preferably, the drive assembly includes a rotary motor, an air injection seat, a rotary sleeve, a telescopic rod, an air receiving groove, a telescopic groove, and a built-in rod. The rotary motor is fixed on a mounting bracket, and an air injection seat is installed below the mounting bracket. The output end of the rotary motor is located inside the air injection seat. A rotary sleeve is connected below the air injection seat, and a telescopic rod is inserted into the rotary sleeve. The bottom end of the telescopic rod is connected to the mounting bracket. An air receiving groove is formed at the center of the mounting bracket, and three transverse telescopic grooves are formed inside the mounting bracket. The telescopic grooves communicate with the air receiving grooves through pipes, and a built-in rod is inserted into each telescopic groove.

[0015] The built-in rod is provided with three rods, which are respectively connected to the rear end of the three docking plates, and a solenoid valve is provided on the pipe that communicates with the air inlet groove.

[0016] The gas injection seat has two flanges installed inside, which are connected by a rod. The lower flange is connected to a rotating sleeve. The upper end of the rotating sleeve is connected to the gas injection seat through a bearing. An external air pipe that communicates with the inside of the gas injection seat is installed on the inner shaft plate of the bearing. One end of the external air pipe communicates with the air inlet groove inside the mounting seat.

[0017] Both the external air pipe and the rotating sleeve are equipped with solenoid valves. One end of the air pipe is connected to the air inlet groove through a telescopic air pipe, and a solenoid valve is installed on the telescopic air pipe.

[0018] The telescopic rod is equipped with side connecting strips on both sides, and the bottom opening of the rotating sleeve is provided with a limiting groove corresponding to the side connecting strip.

[0019] This invention provides another technical solution: a forming method for an insulator blank forming device, comprising the following steps:

[0020] Step 1: Place the insulator blank on the placement ring plate. The motor drives the drive screw to rotate, thereby driving the left and right moving support plates to move towards each other on the connecting plate, thereby driving the left and right clamping rings to clamp and fix the bottom end of the insulator blank.

[0021] Step 2: One end of the air injection seat is connected to the air pump. The air pump injects air into the air injection seat and delivers the gas into the rotating sleeve. Under the action of air pressure, the telescopic rod moves in the rotating sleeve, thereby driving the mounting seat to move down. The conical body and the oblique blade rotate the insulator blank.

[0022] Step 3: When the mounting base rotates, it drives the inner arc-shaped blade and the outer rotating device to rotate and form the insulator blank inside and outside. The adjustment component adjusts the distance between the inner arc-shaped blade and the outer concave blade.

[0023] Preferably, in step three, the vent pipe is connected to the gas via a telescopic vent pipe, thereby driving the drive rod to extend or retract the inner arc-shaped blade, thus adjusting the curvature of the inner arc-shaped blade.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The present invention has three mounting plates, each equipped with an internally connected arc-shaped blade, a vertical blade, and a concave blade. The vertical blade is fixed inside the mounting plate. The mounting plate is connected to the docking plate via bearings, and a motor connected to the mounting plate is mounted on the docking plate. The rear of the docking plate is connected to an adjustment assembly. A cone is provided below the mounting base, and an oblique blade is mounted on the outer end face of the cone. The drive assembly drives the mounting base to move down and rotate. The cone and the oblique blade rotate the insulator blank. By providing three types of cutting tools—internally connected arc-shaped blade, vertical blade, and concave blade—the appropriate tool can be selected to process the inner wall of the insulator blank as needed, improving the adaptability of the entire processing device and enabling the processing of various insulators.

[0026] One end of the drive screw of the present invention is connected to a motor. The bottom ends of the left and right moving support plates are sleeved on the drive screw. The drive screw is provided with opposite threads. When the insulator blank is placed on the placement ring plate, the motor drives the drive screw to rotate, thereby driving the left and right moving support plates to move towards each other on the connecting plate. This causes the left and right clamping rings to clamp and fix the bottom end of the insulator blank, ensuring the stability of the insulator blank during processing and preventing the insulator blank from dislodging.

[0027] One end of the drive rod of the present invention is connected to the inner arc-shaped blade, and one end of the air pipe is connected to the air inlet groove through the telescopic air pipe. The telescopic air pipe is equipped with a solenoid valve. The air pipe is connected to the gas through the telescopic air pipe, thereby driving the drive rod to extend and retract the inner arc-shaped blade, thereby adjusting the curvature of the inner arc-shaped blade. This effectively adjusts the curvature of the inner wall blank as needed, increasing its processing accuracy.

[0028] In this invention, one end of the upper connecting screw and the limiting rod are mounted on a fixed plate, and one end of the fixed plate is fixed to the outer end of the mounting base. One end of the upper connecting screw is connected to a motor on the fixed plate. The motor drives the upper connecting screw to rotate, thereby driving the adjusting bracket, the external bracket, and the outer concave blade to move on the upper connecting screw and the limiting rod. This effectively increases the distance between the adjusting outer concave blade and the inner arc-shaped blade. The outer concave blade and the inner arc-shaped blade work together to simultaneously rotate the insulator inside and out, improving the rotation efficiency. When the outer concave blade moves, the arc-shaped blade and the upper blade of the inner arc-shaped blade intersect. The intersecting blades at the upper end rotate the upper surface of the insulator, ensuring the processing quality of the insulator.

[0029] The present invention includes a telescopic rod inserted into the rotating sleeve. The bottom end of the telescopic rod is connected to the mounting base. Two flanges are installed inside the air injection seat, and the two flanges are connected by a rod body. The lower flange is connected to the rotating sleeve. Side connecting strips are installed on both sides of the telescopic rod. A limiting groove corresponding to the side connecting strip is opened at the bottom opening of the rotating sleeve. One end of the air injection seat is connected to an air pump. The air pump injects air into the air injection seat and delivers the gas into the rotating sleeve. Under the action of air pressure, the telescopic rod moves within the rotating sleeve, thereby causing the mounting base to move downward. The rotating motor drives the rotating sleeve to rotate, which is limited by the limiting groove and the side connecting strip, thereby driving the telescopic rod to rotate. While extending and retracting, the mounting base can also be rotated, improving the driving convenience and flexibility.

[0030] The upper end of the rotating sleeve of the present invention is connected to the air injection seat via a bearing. An external air pipe communicating with the air injection seat is installed on the inner shaft plate of the bearing. One end of the external air pipe is connected to the air inlet groove in the mounting seat. Solenoid valves are installed on both the external air pipe and the rotating sleeve. Gas is introduced into the external air pipe to inject gas into the telescopic groove. By opening and closing the solenoid valve on the pipe, the three built-in rods are driven to telescopically extend and push out, thereby allowing different blades in the inner rotating assembly to be selected for processing as needed. This improves the convenience of adjustment and allows for arbitrary adjustment as needed, increasing the adaptability of the entire device and improving the processing accuracy.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] To address the issue that existing equipment only uses one type of internal turning tool, which prevents tool adjustment during turning and results in poor overall equipment adaptability, please refer to [link / reference needed]. Figures 1-4 This embodiment provides the following technical solution:

[0043] An insulator blank forming apparatus and its forming method include a fixed support 1, a worktable 11 mounted above the fixed support 1, a clamping assembly 2 mounted on the worktable 11, an insulator blank placed on the clamping assembly 2, and a forming assembly 3 mounted on the fixed support 1. The forming assembly 3 includes an inner rotating assembly 31, a mounting base 32, an adjusting assembly 33, a mounting bracket 34, an outer rotating device 35, and a driving assembly 36. One end of the inner rotating assembly 31 is connected to the mounting base 32, one end of the driving assembly 36 is disposed inside the mounting base 32, and the upper part of the driving assembly 36 is fixed to the mounting bracket 34, which is fixed to the worktable 11. The outer rotating device 35 is connected to the mounting base 32 through the adjusting assembly 33. The inner rotating assembly 31 includes a mounting support plate 311, an inner arc-shaped blade 312, a butt joint plate 313, a driving rod 314, a vent pipe 315, a vertical blade 316, and an inner concave blade 317. The mounting support plate 311 is provided with... There are three mounting plates 311, each containing an inner arc-shaped blade 312, a vertical blade 316, and a concave blade 317. The vertical blade 316 is fixed inside the mounting plate 311. The mounting plate 311 is connected to the docking plate 313 via a bearing. A motor connected to the mounting plate 311 is mounted on the docking plate 313. The rear of the docking plate 313 is connected to the mounting base 32. A conical body 321 is located below the mounting base 32. An oblique blade 322 is mounted on the outer end face of the conical body 321. The drive assembly 36 drives the mounting base 32 to move down and rotate. The conical body 321 and the oblique blade 322 rotate the insulator blank. By setting three types of cutting tools—the inner arc-shaped blade 312, the vertical blade 316, and the concave blade 317—the appropriate tool can be selected to process the inner wall of the insulator blank as needed, improving the adaptability of the entire processing device and enabling the processing of various insulators.

[0044] Please see Figure 5The clamping assembly 2 includes a placement ring plate 21, a connecting plate 22, a left clamping ring 23, a right clamping ring 24, a drive screw 25, a left moving support plate 26, and a right moving support plate 27. The two sides of the placement ring plate 21 are connected to the fixed bracket 1 via the connecting plate 22. The left moving support plate 26 is sleeved on the connecting plate 22 on one side of the placement ring plate 21, and the right moving support plate 27 is sleeved on the connecting plate 22 on the other side of the placement ring plate 21. One end of the left moving support plate 26 is connected to the left clamping ring 23, and one end of the right moving support plate 27 is connected to the right clamping ring 24. The drive screw 25 is fixed to the bracket 1 via a collar. Below the placement ring plate 21, one end of the drive screw 25 is connected to the motor. The bottom ends of the left moving support plate 26 and the right moving support plate 27 are sleeved on the drive screw 25. The drive screw 25 is provided with opposite threads. When the insulator blank is placed on the placement ring plate 21, the motor drives the drive screw 25 to rotate, thereby driving the left moving support plate 26 and the right moving support plate 27 to move towards each other on the connecting plate 22, thereby driving the left clamping ring 23 and the right clamping ring 24 to clamp and fix the bottom end of the insulator blank, ensuring the stability of the insulator blank during processing and preventing the insulator blank from dislodging.

[0045] Please see Figure 6 The mounting plate 311 has an inner groove for mounting the inner arc-shaped blade 312. A vent pipe 315 is installed behind the mounting plate 311. A drive rod 314 is installed in the vent pipe 315 via a piston. One end of the drive rod 314 is connected to the inner arc-shaped blade 312. One end of the vent pipe 315 is connected to the air inlet groove 365 via a telescopic air pipe. A solenoid valve is installed on the telescopic air pipe. Gas is introduced into the vent pipe 315 through the telescopic air pipe, thereby driving the drive rod 314 to extend and retract the inner arc-shaped blade 312, thereby adjusting the curvature of the inner arc-shaped blade 312. This effectively adjusts the curvature of the inner wall blank as needed, increasing its machining accuracy.

[0046] To address the issue of existing equipment being unable to simultaneously rotate insulator blanks from both inside and outside, thus affecting rotating efficiency, please refer to... Figure 7 This embodiment provides the following technical solution:

[0047] The external rotation device 35 includes an external bracket 351, an external concave blade 352, a connecting rod 353, and an adjusting bracket 354. The external concave blade 352 is installed on the inner end of the external bracket 351. The rear of the external bracket 351 is connected to the adjusting bracket 354 via a shaft-connected motor. An arc-shaped blade plate 3521 is connected to the upper end of the external concave blade 352. The arc-shaped blade plate 3521 and the blade at the upper end of the inner arc-shaped blade 312 are alternately arranged. The adjusting assembly 33 includes an upper connecting screw 331, a limiting rod 332, an upper connecting plate 333, and a fixing plate 334. The upper connecting plate 333 is fixed on the adjusting bracket 354. The upper end of the adjusting bracket 354 is sleeved on the upper connecting screw 331 and the limiting rod 332 through the upper connecting plate 333. One end of the upper connecting screw 331 and the limiting rod 332 is installed on the fixing plate 354. On the fixed plate 334, one end of the fixed plate 334 is fixed to the outer end of the mounting base 32. One end of the upper connecting screw 331 is connected to the motor on the fixed plate 334. The motor drives the upper connecting screw 331 to rotate, thereby driving the adjusting bracket 354, the external bracket 351, and the external concave blade 352 to move on the upper connecting screw 331 and the limiting rod 332. This effectively increases the distance between the external concave blade 352 and the internal arc blade 312. The external concave blade 352 and the internal arc blade 312 work together to simultaneously rotate the insulator inside and out, improving the rotation efficiency. When the external concave blade 352 moves, the arc blade 3521 and the blade at the upper end of the internal arc blade 312 intersect. The intersecting blades at the upper end rotate the upper surface of the insulator, ensuring the processing quality of the insulator.

[0048] Please see Figure 8 The drive assembly 36 includes a rotary motor 361, an air injection seat 362, a rotating sleeve 363, a telescopic rod 364, an air inlet groove 365, a telescopic groove 366, and an internal rod 367. The rotary motor 361 is fixed on the mounting bracket 34. The air injection seat 362 is installed below the mounting bracket 34. The output end of the rotary motor 361 is located inside the air injection seat 362. The rotating sleeve 363 is connected to the bottom of the air injection seat 362. The telescopic rod 364 is inserted into the rotating sleeve 363. The bottom end of the telescopic rod 364 is connected to the mounting bracket 32. Two flanges are installed inside the air injection seat 362, and the two flanges are connected by a rod. The lower flange is connected to the rotating sleeve 367. The tube 363 is connected, and side connecting strips are installed on both sides of the telescopic rod 364. The bottom opening of the rotating sleeve 363 is provided with a limiting groove corresponding to the side connecting strip. One end of the air injection seat 362 is connected to the air pump. The air pump injects air into the air injection seat 362 and delivers the gas into the rotating sleeve 363. Under the action of air pressure, the telescopic rod 364 moves within the rotating sleeve 363, thereby causing the mounting seat 32 to move down. The rotating motor 361 drives the rotating sleeve 363 to rotate. The limiting groove and the side connecting strip limit the rotation, thereby driving the telescopic rod 364 to rotate. While telescopically extending and retracting, the mounting seat 32 can also be rotated, improving the convenience and flexibility of driving.

[0049] Please see Figure 9 An air inlet groove 365 is provided at the center of the mounting base 32. Three transverse telescopic grooves 366 are provided inside the mounting base 32. The telescopic grooves 366 are interconnected with the air inlet grooves 365 via connecting pipes. Three internal rods 367 are inserted into the telescopic grooves 366, each connecting to the rear end of a mating plate 313. A solenoid valve is installed on the connecting pipe that communicates with the air inlet grooves 365. The upper end of the rotating sleeve 363 is connected to the air injection seat 362 via a bearing. A connecting plate is mounted on the inner shaft plate of the bearing. 2. An external air pipe is interconnected with the inner air groove 365 of the mounting base 32. Solenoid valves are installed on both the external air pipe and the rotating sleeve 363. Gas is introduced into the external air pipe to inject air into the telescopic groove 366. By opening and closing the solenoid valve on the pipe, the three built-in rods 367 are driven to telescopically extend and push out, so that different blades in the inner rotating assembly 31 can be selected for processing as needed, improving the convenience of adjustment and allowing for arbitrary adjustment as needed, increasing the adaptability of the entire device and improving the processing accuracy.

[0050] This invention provides another technical solution: a forming method for an insulator blank forming device, comprising the following steps:

[0051] Step 1: Place the insulator blank on the placement ring plate 21. The motor drives the drive screw 25 to rotate, thereby driving the left moving support plate 26 and the right moving support plate 27 to move towards each other on the connecting plate 22, thereby driving the left clamping ring 23 and the right clamping ring 24 to clamp and fix the bottom end of the insulator blank.

[0052] Step 2: One end of the air injection seat 362 is connected to the air pump. The air pump injects air into the air injection seat 362 and delivers the gas into the rotating sleeve 363. Under the action of air pressure, the telescopic rod 364 moves within the rotating sleeve 363, thereby causing the mounting seat 32 to move down. The conical body 321 and the oblique blade 322 rotate the insulator blank.

[0053] Step 3: When the mounting base 32 rotates, it drives the inner arc-shaped blade 312 and the outer rotating device 35 to rotate and form the insulator blank inside and outside. The adjusting component 33 adjusts the distance between the inner arc-shaped blade 312 and the outer concave blade 352.

[0054] Working principle: During the insulator spinning process, according to... Figure 1 , Figure 2 and Figure 3 The system is equipped with three types of cutting tools: an inwardly curved blade 312, a vertical blade 316, and a concave blade 317. The appropriate tool can be selected to machine the inner wall of the insulator blank as needed. Figure 4 The insulator blank is rotated within the body of the conical body 321 and the oblique blade 322, according to... Figure 5The insulator blank is placed on the placement ring plate 21. The motor drives the drive screw 25 to rotate, thereby driving the left moving support plate 26 and the right moving support plate 27 to move towards each other on the connecting plate 22. This causes the left clamping ring 23 and the right clamping ring 24 to clamp and fix the bottom end of the insulator blank. Figure 6 The vent pipe 315 connects to the gas supply via a telescopic vent pipe, thereby driving the drive rod 314 to extend or retract the inner arc-shaped blade 312, thus adjusting the curvature of the inner arc-shaped blade 312. This effectively adjusts the curvature of the inner wall of the billet as needed. Figure 7 The motor drives the upper lead screw 331 to rotate, thereby causing the adjusting bracket 354, the outer bracket 351, and the outer concave blade 352 to move on the upper lead screw 331 and the limit rod 332, effectively increasing the distance between the adjusting outer concave blade 352 and the inner arc-shaped blade 312. Furthermore, the outer concave blade 352 and the inner arc-shaped blade 312 work together to simultaneously rotate the insulator inside and out. Figure 8 An air pump injects air into the air injection seat 362, delivering the gas to the rotating sleeve 363. Under the pressure of the air, the telescopic rod 364 moves within the rotating sleeve 363, thereby causing the mounting base 32 to move downwards. The rotating motor 361 drives the rotating sleeve 363 to rotate, which is limited by the limiting slot and the side connecting strip, thus causing the telescopic rod 364 to rotate. Simultaneously with the extension and retraction, the mounting base 32 rotates. Figure 9 Gas is introduced into the external air pipe to inject air into the telescopic groove 366. By opening and closing the solenoid valve on the pipe, the three built-in rods 367 are driven to extend and retract, thereby allowing different blades in the inner rotating assembly 31 to be selected for processing as needed.
