Detailed Description

The invention is illustrated below by means of specific examples, without however limiting the invention.

Example 1

As shown in fig. 1, 2,5 and 6, in this embodiment, a double-end automatic discharging and shrinking device is provided, which includes a feeding unit 1, a clamping unit 2 and a shrinking mechanism 3, a feeding cavity for placing a pipe fitting 4 is arranged in the feeding unit 1, a discharge hole for discharging a single pipe fitting 4 is arranged in the feeding cavity, and in the feeding of the pipe fitting 4, the pipe fitting 4 is neatly stacked in the feeding groove. In order to achieve an orderly discharge, the discharge opening can be specially designed at the bottom of the feed trough. In this way the tube 4 located at the very bottom can be pushed out directly through the discharge opening. It is important that only one tube 4 is discharged per operation, ensuring the accuracy of the discharge. When the bottommost pipe fitting 4 is pushed away from the discharge hole, the pipe fitting 4 stacked above naturally slides downwards due to the action of gravity, fills the gap and realigns with the discharge hole, and the process can be continuously carried out, so that the pipe fitting 4 is sequentially and orderly discharged from the feed groove. The design effectively ensures continuous supply and accurate discharge of the pipe fitting 4, and improves the working efficiency.

The clamping unit 2 is located at the outlet of the discharge hole, the clamping unit 2 can push the pipe fitting 4 discharged from the discharge hole away from the position of the discharge hole, after the pipe fitting 4 at the bottommost part is pushed away from the discharge hole, the pipe fitting 4 stacked above can naturally slide downwards due to the action of gravity to fill the gap and realign with the discharge hole, the clamping unit 2 comprises a clamping position, a pushing device capable of pushing the single pipe fitting 4 discharged from the discharge hole to the clamping position is arranged on the clamping unit 2, and in a pipe fitting 4 feeding system, the pushing device can adopt a movable push plate to realize accurate control. The initial position of this push plate is set on one side of the outlet, ensuring that it can easily access the bottom tube 4. When the discharging is needed, the push plate can move forward, and the pipe fitting 4 positioned at the bottom of the discharging hole is accurately pushed to a preset clamping position. Once the tubular 4 is gripped or removed, the push plate will quickly return to its original position awaiting the next operation. In the process of returning the push plate to the initial position, the pipe fitting 4 stacked above naturally slides down due to the action of gravity, fills the gap left by the removed pipe fitting 4, and is aligned to the discharge port again. This process is continuous, ensuring a continuous feed of the tube 4. By this design, the system is able to ensure that only one tube 4 is pushed into the gripping position at a time while maintaining a stable stack of upper tubes 4, thereby enabling an orderly, efficient tube 4 supply process.

The pipe shrinking mechanism 3 comprises two pipe shrinking heads 301 arranged at two sides of the clamping position, the two pipe shrinking heads 301 can move towards the inner sides of the pipe shrinking position, and when the pipe shrinking heads 301 at the two sides move towards each other, a specific space is formed, wherein the pipe fitting 4 is accurately placed between the two pipe shrinking heads 301. Each of the reducer heads 301 is provided with reducer holes 304 which are precisely positioned on the end of the pipe 4. Subsequently, the reducer head 301 begins to exert an appropriate pressure on the tube 4, at which point the reducer aperture 304 will tightly wrap around and compress the corresponding portion of the tube 4. This pressure results in the two ends of the tube 4 simultaneously being subjected to an inward uniform compressive force, which in turn results in simultaneous inward shrinkage deformation of the two ends of the tube 4. By doing so, both ends of the tube member 4 can successfully complete the tube-shrinking work.

Wherein, the internally mounted of draw head 301 has the wheel 302 of polishing that can rotate, is equipped with the position of polishing on the wheel 302 of polishing, and when the position of polishing contacted with the tip of pipe fitting 4, the position of polishing can polish simultaneously along the inner edge and the outer edge of pipe fitting 4 tip, when draw head 301 carries out the draw operation, and the wheel 302 of polishing that its inside was equipped with can polish the processing to the tip of pipe fitting 4 in step. By the aid of the design, the pipe fitting 4 does not need to be conveyed to the next working procedure for independent polishing after the pipe shrinkage is completed, so that the working procedure is simplified, and an additional end polishing working procedure is omitted. This not only improves overall work efficiency, but also reduces material handling and waiting time during production.

Example two

As shown in fig. 1 to 6, on the basis of the first embodiment, the present embodiment provides a polishing function inside the pipe shrinking mechanism 3, specifically as follows:

The inside of the pipe shrinking head 301 is provided with a pipe shrinking hole 304 with one end open, the grinding wheel 302 is rotatably arranged in the pipe shrinking hole 304, one side of the grinding wheel 302, which is close to the orifice of the pipe shrinking hole 304, is provided with an annular groove 303 with a V-shaped section, two conical surfaces on the annular groove 303 are respectively contacted with the inner edge and the outer edge of the end part of the pipe fitting 4, the annular groove 303 is formed by two conical surfaces, and the two conical surfaces form a V-shaped structure at the contact point. Specifically, the inner conical surface contacts the inner edge of the end of the tube 4, while the outer conical surface contacts the outer edge of the end of the tube 4. When grinding wheel 302 begins to rotate, the two conical surfaces are in rotary contact with the inner edge and the outer edge respectively, so that synchronous grinding is realized. If deep grinding is required, the two conical surfaces can form chamfers on the inner edge and the outer edge of the pipe fitting 4, so that the end of the pipe fitting 4 is processed more finely and completely.

The inside anchor ring of shrink tube hole 304 is the conical surface, and the conical surface diameter that is close to shrink tube hole 304 inboard is less than the conical surface that is close to the outside, and the hole bottom department of shrink tube hole 304 is equipped with the groove of stepping down 305, and grinding wheel 302 rotates to install in the groove of stepping down 305, and the design in groove of stepping down 305 ensures that can form a round hole in shrink tube hole 304 inside, and the tip of this round hole is processed into the plane by the accuracy. This plane maintains a certain clearance with the end of the grinding wheel 302 and is designed such that the grinding wheel 302 can make unobstructed contact with the outer edge of the end of the pipe 4 when rotated. By the arrangement, the situation that the outer edge of the pipe fitting 4 is tightly attached to the side wall of the shrinkage pipe hole 304 is effectively avoided, and smooth polishing of the outer edge of the pipe fitting 4 is ensured.

The feeding unit 1 comprises a feeding box 101, a feeding cavity is formed in the feeding box 101, the bottom of the feeding cavity is a conical surface, a discharge hole is formed in the lower end of the conical surface, and under the action of gravity, a pipe fitting 4 stacked in the feeding cavity can move downwards along the conical surface and finally is discharged from the discharge hole.

The side wall of the discharge hole is provided with a movable conveyor belt 102, one section of the outer surface of the conveyor belt 102 is provided with a friction belt 103, and a rotary roller is driven by a motor to rotate in the feed box 101, and the conveyor belt 102 is sleeved on the rotary roller. When the conveyor belt 102 runs to a side near the discharge port, it assumes an upward conveying state. Notably, the main body portion of the conveyor belt 102 is not in direct contact with the tube 4. However, when the friction belt 103 on the conveyor belt 102 rotates to a position close to the pipe member 4, it comes into contact with the pipe member 4 and drives them upward. The friction belt 103 does not contact the lowermost tube 4, thereby ensuring that a certain gap is maintained between the lowermost tube 4 and the tube 4 thereabove. Such a design facilitates a smoother transfer of the lowermost tube 4.
