Description

[0071] A driven gear 702 meshes with the driving rack 701;

[0072] The second gear 703 meshes with the first rack 605 .

[0073] Further, such as Figure 6 As shown, there are two conveying cages 201, both of which are rotatably arranged on the bracket 1;

[0074] The feeding assembly 2 also includes:

[0075] There are two synchronous pulleys 203, which are respectively installed on the two conveying cages 201;

[0076] A synchronous belt 204 is provided on the synchronous pulley 203 and is used to connect the two synchronous pulleys 203;

[0077] A first bevel gear 205 and a second bevel gear 206 meshing therewith, wherein the first bevel gear 205 is installed at the output end of the driving motor 202 , and the second bevel gear 206 is connected to one of the conveying cages 201 .

[0078] Specifically, the synchronous pulley 203 mentioned above is a toothed pulley, and the synchronous belt 204 is a toothed synchronous belt, which effectively avoids slipping.

[0079] Further, such as Figure 5 As shown, a discharge trough is provided on the top of the bracket 1, and two first connecting frames 8 and a second connecting frame 9 are installed on the bracket 1, wherein a through slot is provided on one of the first connecting frames 8, and the setting of the through slot allows the movement of the driving rack 701 to be unimpeded;

[0080] The shrinking module 401 is slidably disposed on the first connecting frame 8;

[0081] The blocking block 610 and the connecting block 611 are both slidably disposed on the second connecting frame 9 .

[0082] The discharge trough is tilted as a whole, and its lowest point is above the conveying cage 201 , so that the thin-walled tube falls on the conveying cage 201 .

[0083] Further, such as Figure 8 As shown, there are two fixed clamping blocks 302, one of which is connected to the first connecting frame 8, and the other is connected to the second connecting frame 9;

[0084] The fixed clamp block 302 is provided with a first half groove, in which a rubber pad is installed;

[0085] The shape of the connecting block 303 is concave;

[0086] The number of the movable clamping blocks 301 is also two, which are distributed at both ends of the connecting block 303;

[0087] The movable clamping block 301 is provided with a second half groove and four square grooves, wherein a rubber pad is installed in the second half groove, and the same side of every two square grooves is tangent to one side of the second half groove. A positioning block 305 is slidably arranged in the square groove, and a spring 306 is installed at the bottom of the positioning block 305, and the bottom of the spring 306 is connected to the square groove.

[0088] Specifically, the fixed clamp block 302 and the movable clamp block 301 are both provided with two, corresponding to the above-mentioned middle shrinking pipe opening work and cleaning work. When viewed from the main direction, the two fixed clamp blocks 302 and the movable clamp block 301 are distributed on the left and right, wherein the one on the left end corresponds to the cleaning work, and the one on the right end corresponds to the shrinking pipe opening work;

[0089] The positioning block 305 is used to assist in positioning the thin-walled tube and to assist in limiting the thin-walled tube during the lifting process. When the positioning block 305 contacts the fixed clamping block 302 , the positioning block 305 is forced to move into the square groove and squeeze the spring 306 .

[0090] Note: After cleaning, the workpiece moves synchronously with the clamp block 301 and returns to the conveying cage 201, which continues to convey the workpiece. A collection frame is placed at the end of the conveying cage 201 to collect the processed thin-walled tubes.

[0100] The blocking block 610 is mounted with a first adjustment plate 620, on which two groups of teeth are intermittently arranged, namely, first teeth and second teeth, wherein the first teeth mesh with the first gear 608, and the second teeth mesh with the third gear 617;

[0101] The connecting block 611 is mounted with a second adjusting plate 621 , and the second adjusting plate 621 is fixed with a third tooth, which is meshed with the third gear 617 .

[0102] Specifically, when the piston 604 moves upward, the air in the connecting chamber 603 is squeezed from the connecting pipe into the pressure storage chamber 601 by the thrust of the piston 604. During this process, the airbag 602 filled with inert gas is compressed and deformed and is in a pressure storage state. When the pressure storage is completed (the piston 604 moves to above the pipe mouth of the connecting pipe), the airbag 602 is no longer under force and is instantly reset to release the air accumulated in the pressure storage chamber 601, and the iron filings are cleaned up by the impact force of the compressed air released instantly.

[0103] Further, such as Figure 14 to Figure 15 As shown, the transmission assembly 7 also includes:

[0104] A stand 704, the driven gear 702, the first gear 608 and the second gear 703 are all rotatably disposed on the stand 704;

[0105] A first transmission block 705 is rotatably disposed on the stand 704, wherein one end of the first rotation block is connected to the driven gear 702;

[0106] A second transmission block 706 is rotatably disposed on the stand 704, and one end of the second transmission block 706 is connected to the second gear 703;

[0107] The ratchet mechanism 707 is provided between the first transmission block 705 and the second transmission block 706 and is used to transmit a unidirectional rotational force;

[0108] The ratchet mechanism 707 comprises:

[0109] The inner ratchet 707a has one end rotatably disposed in the annular groove on the first transmission block 705 and the other end connected to the second transmission block 706;

[0110] A ratchet pawl 707b is disposed at the ratchet teeth of the inner ratchet wheel 707a, and a cross bar is rotatably disposed on the ratchet pawl 707b, and the cross bar is mounted on the first transmission block 705;

[0111] The reset spring plate is arranged at one end of the pawl 707b, and the reset spring plate is installed on the first transmission block 705. The setting of the reset spring plate provides abutment force for the pawl 707b.

[0112] A method of an automatic processing device for thin-walled tubes is as follows:

[0113] The cut thin-walled pipe workpieces are sequentially placed through the discharge trough, and the workpieces fall from the discharge trough onto the conveying cage 201. The first bevel gear 205 is driven by the driving motor 202 to rotate, and then the second bevel gear 206 is driven to rotate one of the conveying cages 201. With the cooperation of the synchronous belt 204 and the synchronous pulley 203, the other conveying cage 201 is synchronously rotated to convey the workpieces.

[0114] When the workpiece is transported to the bottom of the shrinking tube assembly 4 (at this time, the workpiece that has been shrunk and punched stops under the cleaning assembly 6), the driving motor 202 stops, and the first electric push rod 304 starts, driving the connecting block 303 to move, so that the movable clamping block 301 is driven. During the rising process, the movable clamping block 301 first receives the workpiece and limits the workpiece through the positioning block 305 until the movable clamping block 301 contacts with the fixed clamping block 302, thereby clamping and fixing the workpiece;

[0115] Then the second electric push rod 402 is started to drive the shrinking module 401 to move, and shrink the pipe opening of the workpiece. After the shrinking is completed, the second electric push rod 402 drives the shrinking module 401 to reset;

[0116] After the necking module 401 is reset, the third electric push rod 503 is started, driving the moving frame 501 to move, driving the punching head 502 to move, and after the punching head 502 moves to a certain position, the workpiece is punched. After the punching is completed, the moving frame 501 is reset by the third electric push rod 503;

[0117] The synchronous belt 204 for resetting the shrinking module 401 drives the rack 701 to move, and the driving rack 701 drives the driven gear 702 to rotate, driving the first transmission block 705, and the first transmission block 705 drives the ratchet 707b to move. In this rotation direction, the ratchet 707b can drive the inner ratchet 707a to rotate (Note: when the shrinking module 401 approaches, that is, when the workpiece is shrunken, the driving rack 701 is also driven, so that the driven gear 702 is driven, but in this rotation direction, the inner ratchet 707a is not rotated), the inner ratchet 707a drives the second transmission block 706 to move, drives the second gear 703 to rotate, and the movement of the second gear 703 drives the first rack 605 to move, the synchronous belt 204 drives the connecting plate 618 and the connecting rod 606 to move, squeezes the reset spring 609, and drives the piston 604 to move in the connecting groove to store air pressure;

[0118] The movement of the first rack 605 is synchronously driven by the belt 204 to drive the second rack 607, and the second rack 607 drives the first gear 608 to rotate, and the first gear 608 drives the first adjustment plate 620 to move, and the first adjustment plate 620 drives the blocking block 610 to move, so that the blocking block 610 is sleeved on one end of the workpiece, and the first adjustment plate 620 also drives the third gear 617 to rotate synchronously with the belt 204, and the third gear 617 drives the second adjustment plate 621 to move, and the second adjustment plate 621 drives the connecting block 611 to move, so that the connecting block 611 is sleeved on the other end of the workpiece;

[0119] When the piston 604 moves to the top of the connecting pipe, the compressed air is released, and the iron filings in the pipe are blown out by the high-speed airflow of the compressed air.

[0120] When the driving rack 701 stops moving, the driving rack 701 and the driven gear 702 are disengaged (i.e., the teeth of the two are no longer meshing), and the reset spring 609 is no longer under force. Under the action of the reset spring 609, the first rack 605 is driven to reset, driving the piston 604 to move, and air is sucked into the connecting chamber 603 to prepare for the next cleaning;

[0121] As the first rack 605 moves, the second rack 607 is driven to move until the second rack 607 is meshed with the first gear 608, which drives the first gear 608 to reverse, driving the blocking block 610 and the connecting block 611 to separate from the workpiece, thereby completing the cleaning work.

[0122] The above is only a preferred embodiment of the present application and does not impose any form of limitation on the present application. Simple modifications, equivalent changes or modifications made without departing from the technical solution of the present application shall fall within the scope of protection of the present application.
