Description

Technical Field

[0001] The utility model belongs to the technical field of flanging machines, and in particular relates to a large-scale head spinning and flanging machine. Background Art

[0002] At present, when manufacturing the large-diameter head parts of pressure vessels, a spinning flanging machine is usually used. It consists of a column also known as a front support beam, a main transmission system, an upper and lower beams, an upper clamp, a lower clamp, a diameter scale, a side plate frame, a forming wheel mechanism, an automatic profiling scale, an automatic profiling mechanism, a pressure wheel, a forming wheel loading and unloading device, a support plate mechanism, an upper and lower material trolley and a head bevel cutting device. One side is a column also known as a front support beam, and the other side is a frame composed of a side plate frame connected with the upper and lower beams. The side plate frame is composed of left and right side plates made as a whole. An upper clamp driven by a hydraulic cylinder is installed in the middle of the upper beam. A forming wheel and its loading and unloading device of a forming wheel mechanism driven by a motor are installed in the upper part of the side plate frame, corresponding to the forming wheel mechanism of the forming wheel, and between the clamping mechanism and the A diameter ruler is installed flat on the front side surface of the beam between the side panel frames, corresponding to the position of the forming wheel; an automatic profiling mechanism consisting of a three-cylinder four-link parallelogram flexible radius and a pressure wheel driven by it is installed in the lower part of the side panel frame; corresponding to the automatic profiling mechanism, an automatic profiling ruler is installed flat on the upper part of the left side panel surface, corresponding to the outer position of the flange of the processed head; a support plate mechanism is symmetrically installed on the left and right end surfaces of the bottom of the side panel mechanism, consistent with the upper clamp of the upper beam; a lower clamp driven by a hydraulic cylinder is installed on the lower beam, and a loading and unloading trolley for loading and unloading the processed heads is configured; a main transmission system driven by a motor is installed on the column, and its main transmission system can make the upper and lower clamps move linearly through chain transmission and a lead screw, respectively, to adapt to the processing of heads of different diameters.

[0003] When the head blank is to be subjected to spinning and flanging, first, according to the required head diameter, the steel plate is cut out to form the unfolded head blank corresponding to the head diameter, and the head blank is pressed into a disc shape by a drum press, that is, the central part of the head is pressed into the required radius, and then the head blank is flanging by a spinning and flanging machine, that is, the edge of the head is spun into the required curvature. At this time, the forming wheel corresponding to the curvature radius of the processed head flanging is installed on the main shaft of the motor-driven forming wheel mechanism, and the automatic profiling center is adjusted to the scale line corresponding to the curvature radius of the forming wheel according to the automatic profiling ruler, and then the head blank is moved To the bottom of the forming wheel, make the starting point of rotation - arc contact point close to the forming wheel, turn on the power, start the forming wheel of the main shaft in the forming wheel mechanism, the head blank rotates driven by the friction, turn on the hydraulic system to close the cylinder, and make the pressure wheel close to the starting point of the head blank by adjusting the extension rods of the front and rear synchronous cylinders. At this time, close the cylinder that drives the pressure wheel with the extended cylinder rod. The pressure wheel beam rises in parallel under the action of the front and rear synchronous cylinders, and the pressure wheel will rise along the forming wheel under the control of the fixed length of the cylinder rod extended from the closed cylinder; in this way, after multiple passes of automatic contour spinning, the flanging forming process of the head can be gradually completed.

[0004] Then, when the existing head spinning and flanging machine performs spinning and flanging on a large head with a thin wall thickness, although the bottom of the head has been fixed, the rotating head is still easily affected by the forming wheel and the pressure wheel to swing and oscillate, especially for a large head with a thin wall thickness. Therefore, the head needs to be slowly spun and flanging when processing it, and the processing efficiency needs to be further improved. In view of this, the present utility model is specially proposed. Utility Model Content

[0019] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] Reference Figure 1-Figure 3 A large-scale head spinning and flanging machine includes a spinning assembly 1, on the upper and lower ends of one side of the spinning assembly 1, an upper shell 2 and a lower shell 3 are fixedly installed respectively, and also includes: a limit assembly for locking the head, installed on the lower shell 3; a driving part for driving the limit assembly to move, installed on the lower shell 3; a first hydraulic telescopic rod 201, fixedly connected to the upper shell 2 through a support plate; a first rotating disk 202, rotatably connected to the telescopic end of the first hydraulic telescopic rod 201; a push rod 203, equidistantly installed on the first rotating disk 202 at a circumference; a push head 204, fixedly connected to the lower end of the push rod 203.

[0022] The limiting assembly includes a moving block 303, a second hydraulic telescopic rod 305, a second rotating disk 306, a threaded rod 307 and a locking nut 308. The moving block 303 is slidably connected in the lower shell 3, the second hydraulic telescopic rod 305 is fixedly connected to the moving block 303, the second rotating disk 306 is rotatably connected to the telescopic end of the second hydraulic telescopic rod 305, the threaded rod 307 is fixedly connected to the middle position of the second rotating disk 306, and the locking nut 308 is threadedly connected to the threaded rod 307.

[0023] The driving part includes a motor 301 and a screw rod 302. The motor 301 is fixedly connected to one end of the lower shell 3 away from the spinning assembly 1. The screw rod 302 is rotatably connected in the lower shell 3. One end of the screw rod 302 away from the spinning assembly 1 is fixedly connected to the output end of the motor 301. The moving block 303 is threadedly connected to the screw rod 302.

[0024] When the head blank plate has completed the preliminary forming process and needs to be flanging the head blank plate, the staff can place the head blank plate on the second rotating disk 306 and make the threaded rod 307 pass through the through hole in the center of the head. Then the locking nut 308 can be screwed on the threaded rod 307 to firmly lock the head on the second rotating disk 306. After the head is fixed, the motor 301 can be started to drive the screw rod 302 to rotate. The screw rod 302 can move the head to the side close to the spinning assembly 1 through the moving block 303. When the head moves to the designated position, the first hydraulic telescopic rod 201 is just above the head. Then the first hydraulic telescopic rod 201 can be started. 01, the first hydraulic telescopic rod 201 can drive the first rotating disk 202 to move downward, and the first rotating disk 202 will drive the top head 204 to move downward through the top rod 203 until the top head 204 is tightly against the inner wall of the head, and then the spinning assembly 1 can be controlled to perform spinning and flanging operations on the head until the spinning and flanging processing of the head is completed. Through the coordinated use of the first hydraulic telescopic rod 201, the first rotating disk 202, the top rod 203 and the top head 204, the spinning assembly 1 performs spinning and flanging processing on the head, and the head can be limited, so that the head can rotate more smoothly, avoiding the head from shaking too much during spinning and flanging, affecting the processing quality of the head, and effectively ensuring the stability of the head during rotation.

[0025] Embodiment 2:

[0026] Reference Figure 1-Figure 3 , a large-scale head spinning and flanging machine, is basically the same as Example 1, and further: the upper ends of both sides of the moving block 303 are symmetrically fixedly connected with L-shaped limit plates 304, and the L-shaped limit plates 304 slide on the lower shell 3. Through the setting of the L-shaped limit plates 304, the moving block 303 can be supported to avoid the weight of the head and the limit assembly being all pressed on the screw rod 302, causing a large load on the screw rod 302.

[0027] The push rod 203 is a T-rod, which is slidably connected to the first rotating disk 202. A tension spring 205 is sleeved on the push rod 203. The two ends of the tension spring 205 are respectively fixedly connected to the first rotating disk 202 and the upper end of the push rod 203. Through the setting of the tension spring 205, when the top head 204 is tightly against the head cover, it can play a certain buffering role on the top head 204, so that the head cover can have a certain range of fluctuation, avoid tight limiting of the head cover, and cause deformation of the head cover during spinning and flanging, thereby effectively ensuring the quality of processing of the head cover.

[0028] A circle of rubber ring 309 is fixedly connected to the second rotating disk 306, and the top head 204 is a rubber ball. When the end cap is fixedly installed on the second rotating disk 306 through the threaded rod 307 and the locking nut 308, and the top head 204 presses against the end cap to complete the limit fixation of the end cap, the rubber ring 309 and the rubber ball can protect the end cap to prevent the top head 204 and the second rotating disk 306 from causing pressure damage to the end cap when the top head 204 applies a large pressure to the end cap, thereby reducing the quality of the end cap.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
