Description

一种铜管连续拉伸机A copper tube continuous stretching machine

【技术领域】【Technical field】

本发明涉及一种铜管连续拉伸机，属于铜管加工领域。The invention relates to a copper tube continuous stretching machine, which belongs to the field of copper tube processing.

【背景技术】【Background technique】

铜管的加工工艺一般经过熔铸、轧制、预拉伸和盘拉等工艺，轧制完成后的预拉伸一般都采用液压拉伸机拉伸，因为液压拉伸机拉力大，当经过液压拉伸机拉拔后的铜管直径变小、壁厚变薄，然后再输送至拉力相对较小的盘拉机拉伸。传统的预拉伸工艺一般都只采用一台液压拉伸机拉伸，预拉伸效率低，影响生产效率，而且只经过一次预拉伸的铜管在盘拉机进行拉伸时，也会造成盘拉机的负荷大，拉伸效率低，从而导致生产成本高。The processing technology of copper pipes generally goes through casting, rolling, pre-stretching and coil drawing. The pre-stretching after rolling is generally stretched by hydraulic stretching machine, because the hydraulic stretching machine has a large pulling force. The diameter of the copper pipe drawn by the drawing machine becomes smaller and the wall thickness becomes thinner, and then it is sent to the coil drawing machine with relatively small pulling force for stretching. The traditional pre-stretching process generally uses only one hydraulic stretching machine for stretching, and the pre-stretching efficiency is low, which affects production efficiency. Moreover, when the copper tube that has only been pre-stretched once is stretched on the coil stretching machine, it will also The load of the coil pulling machine is large, and the stretching efficiency is low, resulting in high production cost.

因此，本发明正是基于以上的不足而产生的。Therefore, the present invention just produces based on above deficiency.

与现有技术相比，本发明有如下优点：Compared with prior art, the present invention has following advantage:

1、本发明的引导机构能将第一液压拉伸机构内的铜管引导至第二液压拉伸机构，因此，在实际生产中可以采用两台液压拉伸机构对铜管进行预拉伸，提高生产效率，经过两次预拉伸的铜管直径变得更细，壁厚更薄，能够降低后续盘拉工艺盘拉机的工作负荷，进而提高盘拉效率，从整体上提高了生产效率，降低生产成本。1. The guide mechanism of the present invention can guide the copper pipe in the first hydraulic stretching mechanism to the second hydraulic stretching mechanism, therefore, in actual production, two hydraulic stretching mechanisms can be used to pre-stretch the copper pipe, Improve production efficiency, the diameter of the copper tube pre-stretched twice becomes thinner, and the wall thickness is thinner, which can reduce the workload of the subsequent coil drawing process, thereby improving the efficiency of coil drawing, and improving production efficiency as a whole ,reduce manufacturing cost.

2、本发明的第一液压拉伸机构对铜管进行第一次拉拔，拉拔出的铜管进入到左摆臂和右摆臂之间时，滑动条相对固定座向上滑动，通过滑动条上齿牙与其两侧的左齿轮和右齿轮啮合，进而驱动左齿轮和右齿轮转动，使得左摆臂和右摆臂相合，从而左摆臂上的左开口槽和右摆臂上的右开口槽相合而围成能够夹持铜管的夹持引导孔，由于第一液压拉伸机构一直在对铜管进行拉拔，所以铜管受到向前的推力，铜管与夹持引导孔之间的摩擦力就推动转动架转动，因此，铜管就在引导夹持部件的引导下从第一液压拉伸机构输出端运动至第二液压拉伸机构输入端并进入到第二液压拉伸机构内，当铜管在第二液压拉伸机构内被夹持住时，引导夹持部件则松开铜管，转动架转动复位。整个结构设计巧妙，而第一液压拉伸机构和第二液压拉伸机构只需采用不同规格的芯头模具就可以实现铜管的二次拉拔，从而在预拉伸工序就使铜管更细，壁厚更薄，提高生产效率，也降低后续盘拉工序盘拉机的工作负荷，降低生产成本。2. The first hydraulic stretching mechanism of the present invention pulls the copper pipe for the first time, and when the drawn copper pipe enters between the left swing arm and the right swing arm, the sliding bar slides upward relative to the fixed seat, and the The teeth on the bar mesh with the left gear and the right gear on both sides, and then drive the left gear and the right gear to rotate, so that the left swing arm and the right swing arm match, so that the left open slot on the left swing arm and the right swing arm on the right swing arm The opening grooves are combined to form a clamping guide hole capable of clamping the copper tube. Since the first hydraulic stretching mechanism has been pulling the copper tube, the copper tube is pushed forward, and the distance between the copper tube and the clamping guide hole The friction force between them pushes the turret to rotate, so the copper pipe moves from the output end of the first hydraulic stretching mechanism to the input end of the second hydraulic stretching mechanism and enters the second hydraulic stretching mechanism under the guidance of the guide clamping parts. In the mechanism, when the copper pipe is clamped in the second hydraulic stretching mechanism, the guide clamping part releases the copper pipe, and the turret rotates and resets.

Thinner, thinner wall thickness, improves production efficiency, and also reduces the workload of the subsequent coil drawing process, reducing production costs.

3、本发明结构简单，设计巧妙，适合推广应用。3. The present invention has simple structure and ingenious design, and is suitable for popularization and application.

When the copper pipe 100 coming out of the first hydraulic stretching mechanism 1 touches the inclined guide plate 11 , the copper pipe 100 will be bent, so that the copper pipe 100 can be more easily clamped by the guide clamping member 33 .

工作原理：working principle:

第一液压拉伸机构1对铜管100进行第一次拉拔，拉拔出的铜管100进入到左摆臂336和右摆臂337之间时，驱动件33a(气缸)驱动滑动条332相对固定座331向上滑动，由于滑动条332上的齿牙333与其两侧的左齿轮334和右齿轮335啮合，在滑动条332向上运动时，滑动条332驱动左齿轮334和右齿轮335转动，使得左摆臂336和右摆臂337摆动而相合，从而左摆臂336上的左开口槽338和右摆臂337上的右开口槽339相合而围成能够夹持铜管100的夹持引导孔330，由于第一液压拉伸机构1一直在对铜管100进行拉拔，所以铜管100受到向前的推力，铜管100与夹持引导孔330之间的摩擦力就推动转动架322转动，因此，铜管100就在引导夹持部件33的引导下从第一液压拉伸机构1输出端运动至第二液压拉伸机构2输入端并进入到第二液压拉伸机构2内，当铜管100在第二液压拉伸机构2内被夹持住时，引导夹持部件33则松开铜管100，扭簧34驱动转动架322和引导夹持部件33转动复位。整个结构设计巧妙，而第一液压拉伸机构1和第二液压拉伸机构2只需采用不同规格的芯头模具就可以实现铜管100的二次预拉伸，从而在预拉伸工序就使铜管100更细，壁厚更薄，提高生产效率，也降低后续盘拉工序盘拉机的工作负荷，降低生产成本。The first hydraulic stretching mechanism 1 pulls the copper pipe 100 for the first time, and when the drawn copper pipe 100 enters between the left swing arm 336 and the right swing arm 337, the driver 33a (air cylinder) drives the slide bar 332 Sliding upward relative to the fixed seat 331, because the teeth 333 on the sliding bar 332 mesh with the left gear 334 and the right gear 335 on both sides, when the sliding bar 332 moves upward, the sliding bar 332 drives the left gear 334 and the right gear 335 to rotate, Make the left swing arm 336 and the right swing arm 337 swing and meet, so that the left open slot 338 on the left swing arm 336 and the right open slot 339 on the right swing arm 337 match to form a clamping guide capable of clamping the copper pipe 100 hole 330, because the first hydraulic stretching mechanism 1 has been pulling the copper tube 100, so the copper tube 100 is pushed forward, and the friction between the copper tube 100 and the clamping guide hole 330 pushes the turret 322 Therefore, the copper pipe 100 moves from the output end of the first hydraulic stretching mechanism 1 to the input end of the second hydraulic stretching mechanism 2 and enters the second hydraulic stretching mechanism 2 under the guidance of the guide clamping member 33, When the copper tube 100 is clamped in the second hydraulic stretching mechanism 2 , the guide clamping part 33 releases the copper tube 100 , and the torsion spring 34 drives the turret 322 and the guide clamping part 33 to rotate and reset. The entire structure is ingeniously designed, and the first hydraulic stretching mechanism 1 and the second hydraulic stretching mechanism 2 can realize the secondary pre-stretching of the copper tube 100 only by using core dies of different specifications, so that the pre-stretching process can be The copper pipe 100 is made thinner and the wall thickness is thinner, which improves production efficiency, reduces the workload of the subsequent coil drawing process, and reduces production costs.
