Description

Technical Field

[0001] The invention relates to the field of needle tube production, and in particular to a high-strength needle tube production process. Background Art

[0002] In the production process of needle tubes, the initial step is to remove the needle tubes from the coiled material. Subsequently, the diameter of the needle tubes will be gradually reduced through specific processing techniques. In order to improve the hardness and toughness of the needle tubes, they will then undergo a heat treatment process of tempering and quenching. The processing process is to first stretch the needle tube to reduce its diameter, and then enhance its physical properties through heat treatment. When the needle tube is removed from the coil, it needs to be fixed with a clamp and moved to the cutting area for cutting.

The needle tube is pulled to the cutting device by the clamping mechanism for cutting. The device can only pull out and cut one needle tube coil.

DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and functions of the present invention clearer and easier to understand, the present invention is further described below in conjunction with the accompanying drawings and specific embodiments:

[0023] like Figures 1 to 4As shown, the present invention discloses a high-strength needle tube production process, which is implemented based on a high-strength needle tube production system, and the high-strength needle tube production system includes: a quenching device, a metal tube thinning device and a multi-needle tube disc simultaneously working pulling and cutting device, the metal tube thinning device is placed next to the quenching device, and the multi-needle tube disc simultaneously working pulling and cutting device is placed next to the metal tube thinning device; the multi-needle tube disc simultaneously working pulling and cutting device includes: an upper pulling and cutting device 1, a lower pulling and cutting device 2 and a rotating drive device 3; the upper pulling and cutting device 1 and the lower pulling and cutting device 2 both include: a frame 11, a storage rotating frame 12, a clamping mechanism 13, a circulating driving mechanism 14 and a cutting mechanism 15, the frame 11 is equipped with a circulating driving mechanism 14, the output end of the circulating driving mechanism 14 is connected to at least three clamping mechanisms 13, and a storage The rotating frame 12 is used to store needle tube disks. The position of the circulating driving mechanism 14 near the rotating storage frame is the clamping station 61. One position of the circulating driving mechanism 14 is the cutting station 62. Another position of the circulating driving mechanism 14 is the discharging station 63. The cutting station 62 is located between the clamping station 61 and the discharging station 63. There is a distance between the clamping station 61 and the cutting station 62, there is a distance between the cutting station 62 and the discharging station 63, and there is a distance between the discharging station 63 and the clamping station 61. A cutting mechanism 15 is installed on the frame 11, and the cutting mechanism 15 is located at the cutting station 62; the circulating driving mechanism 14 of the upper pulling and cutting device 1 is mounted above the circulating driving mechanism 14 of the lower pulling and cutting device 2 through the frame 11; the circulating driving mechanism 14 of the upper pulling and cutting device 1 and the circulating driving mechanism 14 of the lower pulling and cutting device 2 are both driven by the rotating drive device 3. The high-strength needle tube production process includes the following steps: S1, preparing an initial needle tube disc, installing the initial needle tube disc on a quenching device, and the quenching device quenches the initial needle tube disc to obtain a quenched needle tube disc; S2, installing the quenched needle tube disc on a metal tube thinning device, and the metal tube thinning device thins the quenched needle tube disc to obtain a thinned needle tube disc; S3, using a multi-needle tube disc simultaneous working pulling and cutting device to simultaneously cut and segment two thinned needle tube discs to obtain needle tube segments.

[0024] The cutting mechanism 15 includes: a cutting table 151, a cutting seat 152, a stopper 153, a cutting knife 154, a cutting plate 155 and a sliding assembly 156. The cutting table 151 is located at the cutting station 62. The cutting table 151 is fixed to the frame 11. One end of the cutting table 151 protrudes upward with a stopper 1511. The end of the cutting seat 152 close to the stopper 1511 protrudes upward with a push plate. A certain distance is formed between the stopper 1511 and the push plate, and the stopper 1511 and the push plate are connected by a first A spring 157 is connected, and a first sliding component 156 is also provided on the cutting table 151. The cutting seat 152 is slidably connected to the first sliding component 156. A telescopic driving device 158 is provided on the cutting seat 152, and the output end of the telescopic driving device 158 is connected to the cutting plate 155; a cutting knife 154 is provided on the cutting plate 155, and a sliding groove 1531 is provided on the side of the push plate close to the telescopic mechanism, and a block 153 is provided in the sliding groove 1531, and the block 153 is connected to the cutting plate 155. When the clamping mechanism 13 moves to the cutting station 62, the cutting plate 155 at the output end of the telescopic drive device 158 drives the stopper 153 to extend toward the chain end. Since the extension length of the stopper 153 is greater than the extension length of the cutting knife 154, the stopper 153 has already contacted the clamping mechanism 13 when the cutting knife 154 has not yet contacted the needle tube. At this time, as the clamping mechanism 13 moves, the clamping mechanism 13 drives the cutting knife 154 and the telescopic mechanism to move together through the stopper 153, and the spring is deformed; then, the telescopic cylinder continues to extend, so that the cutting knife 154 contacts the needle tube to achieve cutting. During this process, the stopper 153 is always in contact with the clamping mechanism 13, and the clamping mechanism 13 is clamped. The mechanism 13 and the cutting knife 154 will not move in the same direction as the chain transmission direction, ensuring that the cutting knife 154 cuts the needle tube segment next to the clamping mechanism 13, ensuring that the cutting work proceeds smoothly; finally, the telescopic cylinder is retracted, so that the cutting knife 154 and the block 153 both move toward the cutting table 151, and the block 153 is disengaged from the clamping mechanism 13. This clamping mechanism 13 continues to move, and when the spring force drops, the cutting table 151, the block 153 and the cutting knife 154 are pulled back to the initial position, waiting for the next clamping mechanism 13 to arrive. At the same time, the previous clamping mechanism 13 opens to release the needle tube, and the needle tube will fall into the needle tube receiving part to achieve material discharge. In the whole process, the needle tube disc is continuously pulled out of the needle tube segment, continuously cut into needle tube segments, and discharged into the needle tube receiving part.

[0025] Support mechanisms 4 are installed on both sides of the output end of the circulating driving mechanism 14, and the support mechanisms 4 are located between the clamping station and the discharge station 63; the clamping mechanism 13 includes: a mounting seat 131, a lifting seat 133, a clamping assembly 134 and a lifting mechanism 135. The bottom of the mounting seat 131 is connected to the output end of the circulating driving mechanism 14, and the lifting seat 133 is installed above the mounting seat 131. The lifting seat 133 can be lifted and lowered relative to the mounting seat 131. The support mechanism 4 is used to lift the lifting seat 133. The bottom of the lifting seat 133 protrudes upward to form a first clamping block 1332. A clamping assembly 134 located next to the first clamping block 1332 is installed on the lifting seat 133. The clamping assembly 134 is used to cooperate with the first clamping block 1332 to clamp the needle tube segment. The circulating driving mechanism 14 is a chain sprocket drive mechanism, the mounting seat 131 of the clamping mechanism is installed on a chain link, and the needle tube end clamping device adopts the method of installing the clamping mechanism 13 on the chain, and driving the first transmission gear through the driving device to make the chain cyclically move between the first transmission gear and the second transmission gear, so as to move the clamping mechanism 13 from the clamping station to the discharge station 63, so that the clamping mechanism 13 can cyclically move, and then realize the cyclic movement of the clamping structure between the clamping station and the discharge station 63, and the two sides of the chain are respectively The first support block 41 and the second support block 42 are installed higher than the chain. When the clamping mechanism 13 is rotated to the clamping position, the lifting seat 133, the first clamping block 1332 and the clamping assembly 134 will be lifted up by the first support block 41 and the second support block 42. Because the needle tube section has crossed the clamping position 61 before clamping, the first clamping block 1332 and the lifting seat 133 are in a lower position when it needs to be rotated to the side of the clamping position 61. In this way, when the clamping mechanism 13 is rotated, the first clamping block 1332 in the lower position is lifted up by the first support block 41 and the second support block 42. 2 can pass over the pulled needle tube section, so that the needle tube section is aligned with the clamping area before reaching the first support block 41 and the second support block 42. Subsequently, as the chain pulls the clamping mechanism 13 to move, when the clamping mechanism 13 reaches the first slope and the second slope, the first slope and the second slope slowly raise the lifting seat 133 in the clamping mechanism 13, so that the needle tube section is placed between the first clamping block 1332 and the clamping assembly 134, thereby preventing the clamping mechanism 13 driven by the chain from being pulled. The pulled-out needle tube segment is blocked from moving, that is, the first clamping block 1332 is prevented from colliding with the pulled-out needle tube segment when the clamping mechanism 13 moves, and it is ensured that the clamping area can be aligned with the pulled-out needle tube segment when the clamping mechanism 13 rotates to the clamping station 61, so that the first clamping block 1332 surrounds one side of the pulled-out needle tube segment after being lifted by the first support block 41 and the second support block 42, and then the action of clamping the needle tube is subsequently realized. The whole process is convenient and quick and does not require manual removal of the needle tube, which greatly reduces labor costs.

[0026] A lifting mechanism 135 is installed beside the first clamping block 1332, and the lifting mechanism 135 is used to push out the needle tube section between the first clamping block 1332 and the clamping assembly 134; a lifting platform 51 is installed on the frame 11, and a lifting plate 52 is provided on the lifting platform 51. The lifting plate 52 is located at the material discharge station 63, and the lifting plate 52 is used to lift the lifting mechanism 135. When the lifting plate 52 reaches the material discharge station 63, the lifting mechanism 135 is lifted up by the top surface of the lifting plate 52, and the needle tube section of the first clamping block 1332 and the clamping assembly 134 is pushed out, so that the material discharge is smooth.

[0027] The clamping assembly 134 includes: a second clamping block 1342 and a clamping electromagnet. A permanent magnet is installed at the end of the second clamping block 1342, and a clamping electromagnet is installed next to the permanent magnet. When the clamping electromagnet is energized, it repels the permanent magnet and the second clamping block 1342. The second clamping block 1342 cooperates with the first clamping block 1332 to clamp the needle tube section.

[0028] The support mechanism 4 includes: a first support block 41 and a second support block 42, both of which are installed on the top of the frame 11, and a transmission groove is formed between the first support block 41 and the second support block 42, and the output end of the circulating driving mechanism 14 is located in the transmission groove. The ends of the first support block 41 and the second support block 42 are provided with a slope surface, and the slope surface guides the lifting seat 133 to the top surface of the first support block 41 and the second support block 42. The process of the clamping mechanism 13 being transported from the clamping station 61 to the front end of the cutting station 62 and the discharge station 63 in sequence is always supported by the first support block 41 and the second support block 42. When it is between the discharge station 63 and the discharge station 63, the lifting seat 133 and the first clamping block 1332 are in a lower position to prevent the first clamping block 1332 from colliding with the needle tube section that has been pulled out.

[0029] The lifting mechanism 135 includes: a lifting column 1351 and a second spring 1352. The bottom end of the lifting column 1351 is provided with a lifting head 1353. The top end of the lifting column 1351 extends into the lifting hole 1331 provided in the lifting seat 133. The second spring 1352 is sleeved on the lifting column 1351. The two ends of the second spring 1352 are respectively connected to the lifting head 1353 and the lifting seat 133. The lifting column 1351 is in a lower position under the elastic force of the second spring 1352. When it reaches the discharge station 63, the second clamping block 1342 is away from the first clamping block 1332. At the same time, the lifting column 1351 jumps onto the lifting plate 52, and the needle tube disc is ejected from between the first clamping block 1332 and the second clamping block 1342 to ensure smooth discharge.

[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
