Description

Technical Field

[0001] The utility model belongs to the technical field of spinning machines, and in particular relates to a flanging mechanism for a horizontal spinning machine. Background Art

[0002] At present, when manufacturing the large-diameter head parts of pressure vessels, a spinning 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 position of the upper beam. A forming wheel and its loading and unloading device driven by a motor forming wheel mechanism 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 side A diameter scale is installed flat on the front side surface of the beam between the plate 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 plate frame; corresponding to the automatic profiling mechanism, an automatic profiling scale is installed flat on the upper part of the left plate 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 plate 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 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 Under the forming wheel, make the starting point of rotation - arc connection point close to the forming wheel, turn on the power, start the forming wheel of the main shaft in the forming wheel mechanism, and the head blank rotates driven by friction. Turn on the hydraulic system to close the cylinder, and by adjusting the extension rods of the front and rear synchronous cylinders, make the pressure wheel also close to the starting point of the head blank. 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 by 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 machine spins and flanging the head blank, a single flanging assembly is used to perform flanging on the head blank. For a large head with a thin wall, it is easy to swing and oscillate under the influence of the forming wheel and the pressure wheel. Therefore, the head needs to be slowly spun and flanged during processing to avoid damage to the head. However, this leads to low processing efficiency and requires a long time to complete the flanging. In view of this, the present utility model is specially proposed. Utility Model Content

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 flanging mechanism for a horizontal spinning machine includes a flanging assembly 1 and a pressing assembly, wherein the flanging assembly 1 is symmetrically arranged on both sides of the pressing assembly, and further includes: a dual-axis motor 3, fixedly connected to the pressing assembly; a transmission screw 301, symmetrically fixedly connected to the output ends on both sides of the dual-axis motor 3; a moving block 101, fixedly connected to the bottom of the flanging assembly 1, and two moving blocks 101 are respectively threadedly connected to adjacent transmission screws 301; and two sets of moving rollers 102, symmetrically installed at the lower ends of both sides of the flanging assembly 1.

[0022] The clamping assembly includes an L-shaped base 2, a first hydraulic telescopic rod 207, a moving platform 201, a second hydraulic telescopic rod 203, a rotating disk 204, a positioning rod 205 and a locking nut 206. The L-shaped base 2 is installed on the ground by ground bolts. The first hydraulic telescopic rod 207 is fixedly connected to the side wall of the L-shaped base 2.

The second hydraulic telescopic rod 203 is fixedly connected to the moving platform 201. The rotating disk 204 is rotatably connected to the telescopic end of the second hydraulic telescopic rod 203. The positioning rod 205 is fixedly connected to the center of the upper end of the rotating disk 204. The locking nut 206 is threadedly connected to the positioning rod 205. A through opening is opened inside the L-shaped base 2, and the dual-axis motor 3 is fixedly installed in the through opening.

[0023] When the head blank plate has completed the preliminary forming processing and needs to be flanging the head blank plate, the staff can place the head blank plate on the rotating disk 204 and position it through the positioning rod 205, and then the locking nut 206 can be screwed onto the positioning rod 205 until the locking nut 206 is tightly against the head, thereby completing the positioning operation of the head blank plate, and then the first hydraulic telescopic rod 207 can be started, and the first hydraulic telescopic rod 207 will move the head blank plate to the position between the two flanging assemblies 1 through a certain moving platform 201, and then the second hydraulic telescopic rod 203 is started, and the head blank plate can be adjusted to a suitable height, and then the dual-axis motor 3 can be started, and the dual-axis motor 3 will drive the transmission screw 301 to rotate synchronously, and the two transmission The screw rod 301 will pass through the two moving blocks 101, and with the cooperation of the moving roller 102, the two flanging assemblies 1 will be moved closer to the position of the head blank plate. After adjusting the position of the flanging assembly 1, the flanging assembly 1 can be started to perform spinning and flanging operations on the head blank plate. By symmetrically arranging two sets of flanging assemblies 1 on both sides of the clamping assembly, when spinning and flanging the head blank plate, the head blank plate can be spun and flanging on both sides at the same time, which can not only improve the efficiency of the flanging processing of the head blank plate, but also limit the head blank plate from both sides, so that the head blank plate can be rotated more smoothly, avoiding the head blank plate from swaying and oscillating with a large amplitude during spinning and flanging, affecting the processing quality of the head blank plate, and effectively ensuring the stability of the head blank plate during rotation.

[0024] Embodiment 2:
