Referring to fig. 1-8, for blanking of some thin-wall pipe bodies, the cutting part is extruded by the cutting piece, the cutting opening is smaller, at the moment, the pipe orifice needs to be chamfered and shaped by using a chamfering machine, burrs are removed due to machining of the pipe orifice, and in order to facilitate assembly of pipe body parts, the chamfering and shaping process is generally carried out by a worker holding the pipe body parts to align the chamfering machine for chamfering, so that the pipe body parts are prevented from rotating due to friction force of the chamfering machine, the pipe body parts need to be held by the worker with great force, and hands of the worker are seriously damaged in long time;
in order to overcome the defects, the invention designs a shaping fixture for thin-wall pipe parts.
Initially, the clamping member 242 on the clamping assembly 24 is in a vertical state, the opening direction of the placing pipe 2421 is upward, the driven plate 2423 and the driving plate 2424 inside the placing pipe 2421 are in a state of being separated from the inner wall of the placing pipe 2421 (the included angle formed by the driven plate 2423 and the driving plate 2424 is the largest at the moment), the distance between the reciprocating plate 2427 and the placing pipe 2421 is the largest, meanwhile, the driven plate 2423 and the driving plate 2424 are connected through the rotating pins, the protruding part of the driving plate 2424 is sleeved with a rubber sleeve, and the rubber sleeve can be attached to the inner wall of the pipe fitting to be shaped. Because the placing pipe 2421 is in a vertical state, and the protruding part of the driving plate 2424 is initially set to be far away from the inner wall of the placing pipe 2421, the pipe fitting to be shaped can be directly inserted into the placing pipe 2421, and the pipe fitting to be shaped is influenced by self gravity and freely falls to the bottom of the inner wall of the placing pipe 2421, and at the moment, the driven plate 2423 and the driving plate 2424 are both positioned in the space surrounded by the pipe fitting to be shaped.
The existing automatic blanking machine generally adopts a PLC controller to set the blanking length of the pipe body, the lengths of the pipe fittings to be shaped after blanking are consistent, and for blanking of some thin-wall pipe bodies, the invention adopts a clamping piece 242 to replace the traditional manual holding mode: after two groups of pipe fittings to be shaped are placed, the pull rod 241 is manually held to rotate clockwise, the clamping piece 242 performs circular motion (rotates by 1/4) around the fixed seat 23 by means of the shaft rod 245, meanwhile, the arc plate 243 is attached to the inner wall of the arc pipe 221 to slide, so that the clamping piece 242 is ensured to move stably until the placing pipe 2421 falls onto the upper surface of the support 222, at this time, the placing pipe 2421 and the pipe fittings to be shaped are in a horizontal state (the arc plate 243 is completely slid into the arc pipe 221 and combined into a whole to prevent the clamping piece 242 from shifting), the center line of the pipe fittings to be shaped is overlapped with the center line of the power head 13, and the chamfering and shaping precision is greatly improved. Meanwhile, the invention not only realizes the horizontal correction of the pipe fitting to be shaped (the pipe fitting is attached to the bottom of the inner wall of the placing pipe 2421) by means of the angle adjusting process of the clamping piece 242, but also realizes the fixed clamping (including the loosening of the subsequent resetting) of the pipe fitting to be shaped.
Specifically, when the clamping member 242 rotates clockwise, the bevel gear 244 is driven to rotate around the outer surface of the toothed plate 254, the bevel gear 244 rotates around the inside of the shaft rod 245, the rotation of the bevel gear 244 drives the screw rod 2428 to rotate around the inside of the placing pipe 2421 (the side, away from the shaft rod 245, of the bevel gear 244 is in sliding connection with the inside of the screw rod 2428 through the square rod), the rotation of the screw rod 2428 pushes the reciprocating plate 2427 to slide along the inside of the placing pipe 2421 (meanwhile, the screw rod 2428 slides along the outer surface of the square rod), the reciprocating plate 2427 pushes the polish rod 2426 to slide along the inside of the frame 2422, the driving plate 2424 is driven to rotate outwards around the driven plate 2423 by virtue of the pushing block 2425, the rubber sleeve at the protruding part of the driving plate 2424 starts to abut against the inner wall of the pipe fitting, and the expansion forces generated by the two groups of driving plates 2424 are uniform and consistent, so that the pipe fitting is centered and expanded, and the thin-wall pipe body is protected. Finally, the pull rod 241 is pushed forward continuously to drive the loading plate 22, the fixing seat 23, the clamping assembly 24, the adjusting piece 25 and the pipe fitting to be shaped to move forward synchronously (the powerful spring 212 is compressed further to generate elastic deformation) until the cutting opening of the pipe fitting to be shaped contacts the power head 13 rotating at a high speed, and the clamping assembly 24 is matched for clamping and fixing, so that the pipe fitting to be shaped with different lengths in a certain range is subjected to quick chamfering shaping (two groups of pipe fittings to be shaped are performed synchronously).
In summary, the present invention utilizes the initial vertical state of the placing pipe 2421 to facilitate the quick placement of the pipe to be shaped, and simultaneously, by means of the angle adjustment of the placing pipe 2421, the horizontal correction and the fixed clamping of the pipe to be shaped are synchronously realized, the operation mode is simple, only the light rotation is needed, and when the placing pipe 2421 is reset by rotating anticlockwise, the clamping piece 242 automatically releases the clamping of the pipe to be shaped, so that the pipe to be shaped can be quickly taken out.
On the other hand, in order to improve the application range of the clamping assembly 24, the range of the outward expansion angles of the driven plate 2423 and the driving plate 2424 should be adjusted, and the rubber sleeves of the protruding parts are matched to meet the clamping requirements of the pipe fitting with different diameters in a certain range, and secondly, the invention emphasizes that the pipe fitting is allowed to slowly loosen and rotate under the action of friction force in the chamfering process (the two ends of the pipe fitting are abutted by the placing pipe 2421 and the power head 13) according to the requirements of the chamfering process.
Specifically, since each rotation path of the bevel gear 244 is only 1/4 of the toothed plate 254, the number of teeth on the toothed plate 254 is equally divided into three groups, and the numbers of teeth corresponding to the teeth in different areas are different, when the bevel gear 244 engages with different numbers of teeth, even if the bevel gear 244 rotates the same path, the rotation angle of the bevel gear 244 is different, and the "advancing distance" of the pushing reciprocating plate 2427 is different, so that the driving plate 2424 is driven to expand outwardly by different distances, and meanwhile, the rubber sleeve of the protruding part is matched, so that the clamping of pipe fittings with different diameters in a certain range is satisfied. The adjustment mode is as follows: the nut 2521 is rotated by the screwdriver to move to the side of the base 251, at this time, the nut 2521 is separated from the clamping rod 2541, the toothed plate 254 can move to the side of the base 251 along the outer surface of the limiting rod 253 until the clamping rod 2541 is completely separated from the clamping groove 2531, then the region corresponding to the bevel gear 244 can be adjusted by rotating the toothed plate 254, and finally the nut 2521 is locked.
The above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; these modifications or substitutions do not depart from the essence of the corresponding technical solutions from the protection scope of the technical solutions of the embodiments of the present invention.
