[0045] Example 1

[0046] This embodiment provides a feeding device, such as Figure 1-14 As shown, the unloading device is used for unloading the copper tube after expanding it, and the unloading device includes: a clamping component 1, which can clamp the copper tube to prevent it from retreating; a dividing component 2, which can move to the copper tube of the clamping component 1 and expand the copper tube, and the copper tube is transferred to the dividing component 2 after expanding; a receiving component 3, which can move to the bottom of the dividing component 2 to receive the copper tube dropped from the dividing component 2; a pushing component 4, which is arranged opposite to the receiving component 3, and its output end can extend into the receiving component 3 to push out the copper tube in the receiving component 3.

[0047] The copper tube is cut from the straight tube, and during the production process, the cutting device is connected to the feeding device provided in this embodiment. After the straight tube is cut by the cutting device, it will flow into the feeding device of this embodiment.

[0048] More specifically, the clamping component 1 is mainly used to clamp the copper tube. After clamping the copper tube, on the one hand, the copper tube can be expanded, and on the other hand, the straight tube can be prevented from being returned due to incomplete cutting when the material is returned; the dividing component 2 is mainly used to disperse the expanded copper tube to avoid the phenomenon of copper tube stacking due to the flow of multiple copper tubes together; the receiving component 3 is used to cooperate with the dividing component 2 on the one hand to receive the copper tube transferred by the dividing component 2, and on the other hand to cooperate with the pushing component 4; the pushing component 4 is used to push the copper tube in the receiving component 3 to the bending device for the next processing.

[0049] The clamping assembly 1, the material distribution assembly 2, the material receiving assembly 3 and the material pushing assembly 4 in this embodiment are tightly combined together, and the material discharging device has multiple different states through relative sliding. For example, in the initial state, the clamping assembly 1 is located above the material distribution assembly 2, and the material receiving assembly 3 and the material pushing assembly 4 are arranged relatively and are both located below the material distribution assembly 2; when the copper tube needs to be expanded, the material distribution assembly 2 moves to the copper tube of the clamping assembly 1, and the position of the material distribution assembly 2 changes compared with the initial state; and when the material needs to be connected, the material receiving assembly 3 moves to the bottom of the material distribution assembly 2 to connect the material; that is, in different working processes, the positions of the material distribution assembly 2, the material receiving assembly 3 and the material pushing assembly 4 in this embodiment will change, and this change is achieved through the guide rail.

[0050] When the copper tube is processed by the above structure, the copper tube is first placed at the clamping component 1, and the clamping component 1 clamps the copper tube, and then the material distribution component 2 moves to the copper tube to expand the copper tube. After the expansion is completed, the clamping component 1 releases the copper tube, and the copper tube moves to the material distribution component 2 through the grasping component for material distribution, and then the material receiving component 3 moves to the bottom of the material distribution component 2, and the material distribution component 2 transfers the scattered copper tubes to the material receiving component 3, and finally the material pushing component 4 works to push the copper tube in the material receiving component 3 for the next step of processing. In the whole process, firstly, due to the existence of the clamping component 1, it can prevent the copper tube from retreating by clamping the copper tube, and the copper tube is divided by the material distribution component 2 before the material receiving component 3 works, which can effectively avoid the phenomenon of copper tube stacking during the processing. In this way, this embodiment reduces the equipment shutdown problem caused by the retreat and stacking of copper tubes, improves the stability of the equipment, and reduces the generation of waste.

[0051] In a specific embodiment, Figure 5-7 As shown, the clamping assembly 1 includes a first driving unit 11, a support seat 12, a first clamp 13 and a second clamp 14. The first clamp 13 and the second clamp 14 are arranged up and down and are located in the support seat 12. The first driving unit 11 is arranged on the support seat 12 and is connected to the first clamp 13 through a connecting block 15; the first driving unit 11 drives the first clamp 13 to move up and down through the connecting block 15 to clamp or release the copper tube between the first clamp 13 and the second clamp 14.

[0052] More specifically, the first driving unit 11 is an oil cylinder; the support seat 12 includes a first support seat and a second support seat, the first support seat and the second support seat are arranged opposite to each other with a gap therebetween, in the gap, there are a connecting block 15, a first clamp 13 and a second clamp 14 from top to bottom; in a specific working process, the copper tube is located between the first clamp 13 and the second clamp 14, and the oil cylinder can drive the first clamp 13 to move up and down through the connecting block 15. When the copper tube needs to be expanded, the first clamp 13 is in a lower position to clamp the copper tube to prevent it from returning. When the copper tube needs to be transferred, the first clamp 13 is in an upper position so that the copper tube can be transferred.

[0053] In addition, the clamping assembly 1 further comprises an elastic member 16 and a pressing block 17, and the elastic member 16 and the pressing block 17 are arranged inside the first clamping die 13. The elastic member 16 is a spring.

[0054] More specifically, the first support seat, the second support seat and the second clamping die 14 are fixed, the oil cylinder is installed on the first support seat and the second support seat, the connecting block 15 is connected to the oil cylinder, and the oil cylinder drives the connecting block 15 to drive the first clamping die 13 to clamp the copper tube. The spring and the pressing block 17 are installed inside the first clamping die 13, and the pressing block 17 is pressed downward by the force of the spring compression. When the first clamping die 13 is released, the copper tube pushes up the pressing block 17, and the spring is compressed, so that the pressing block 17 presses the copper tube to prevent the copper tube from retreating.

[0055] The lower surface of the first clamping die 13 and the upper surface of the second clamping die 14 have a concave structure matching the shape of the copper tube. Specifically, if the copper tube is a columnar structure, a first arc that is concave upward is provided on the lower surface of the first clamping die 13, and a second arc that is concave downward is provided on the upper surface of the second clamping die 14. When the first clamping die 13 and the second clamping die 14 are matched, the first arc and the second arc are combined into a columnar structure, which can just accommodate the copper tube, so as to prevent the copper tube from shaking during expansion and affecting the expansion effect.

[0056] In a specific embodiment, Figure 8-11 As shown, the material distribution component 2 includes a second driving unit 21, a flaring unit 22, a discharge unit 23, a first guide rail unit 24 and a discharge driving unit 25. The second driving unit 21 is connected to the flaring unit 22, and is used to drive the flaring unit 22 to move along the first guide rail unit 24 to the copper tube of the clamping component 1. The discharge driving unit 25 is connected to the discharge unit 23, and is used to drive the discharge unit 23 to transfer the copper tube to the specified position of the receiving component 3.

[0057] More specifically, the second driving unit 21 includes an electric cylinder 211, a mounting plate 212 and a first pull block 213. The electric cylinder 211 is connected to the first pull block 213 through the mounting plate 212, the first pull block 213 is connected to the discharge unit 23, and the discharge unit 23 is connected to the expansion unit 22. In this way, when the electric cylinder 211 is working, it can drive the entire discharge unit 23 and the expansion unit 22 to move along the first guide rail unit 24 to the required position through the first pull block 213, such as moving to the copper pipe of the clamping assembly 1.

[0058] In addition, the discharge drive unit 25 includes a discharge cylinder 251 , which is connected to the discharge unit 23 via a joint 252 , and is used to drive the discharge unit 23 to transfer the copper tube to a designated position of the receiving assembly 3 .

[0060] More specifically, in this embodiment, in the initial state, the third clamp 233 and the fourth clamp 234 are in close contact, and at this time there is a gap between the fourth clamp 234 and the fifth clamp 235, and the gap is the above-mentioned second space. The copper tube can be located in the second space, and the electric cylinder 211 drives the entire material distribution component 2 to move, aligns the gap between the fourth clamp 234 and the fifth clamp 235 with the copper tube, and then moves the copper tube at the clamping component 1 to the second space through the grabbing component, and then the electric cylinder 211 continues to drive the entire material distribution component 2 to move, so that the copper tube in the second space is transferred to the receiving component 3. After that, the material discharging driving unit 25 drives the material discharging plate 231 to move, thereby moving the fourth clamping die 234 connected to the material discharging plate 231. When the fourth clamping die 234 and the fifth clamping die 235 are in close contact, there is a gap between the fourth clamping die 234 and the third clamping die 233, which is the first space mentioned above. The copper tube can be located in the first space. The electric cylinder 211 drives the entire material distributing component 2 to move, aligns the gap between the fourth clamping die 234 and the third clamping die 233 with the copper tube, and then moves the copper tube at the pressing component 1 to the first space through the grabbing component. After that, the electric cylinder 211 continues to drive the entire material distributing component 2 to move, so that the copper tube in the first space is transferred to the material receiving component 3. It should be noted that the copper tube in the first space and the copper tube in the second space fall at different positions of the material receiving component 3 to avoid the stacking of the copper tubes.

[0061] In a specific embodiment, a third clamping die 233, a fourth clamping die 234 and a fifth clamping die 235 form a clamping die module, and a plurality of clamping die modules are arranged below the fixing plate 232; the flaring unit 22 includes a mounting seat 221 and a flaring needle 222 arranged on the mounting seat 221, and the mounting seat 221 has a plurality of clamping die modules and is respectively arranged between adjacent clamping die modules. Corresponding to the clamping die modules, a plurality of clamping assemblies 1 are also arranged, so that the working efficiency of the unloading device can be improved.

[0062] In a specific embodiment, Fig.12 and Fig.13As shown, the material receiving assembly 3 includes a third driving unit 31, a material dividing plate 32, a material receiving trough unit 33 and a material receiving trough mounting plate 34, wherein the third driving unit 31 is connected to the material dividing plate 32, a plurality of material receiving trough units 33 are arranged and evenly distributed on the material receiving trough mounting plate 34, and the material dividing plate 32 is transversely inserted into the material receiving trough unit 33; the third driving unit 31 drives the material dividing plate 32 to have a first state of blocking the bottom of the material receiving trough unit 33 and a second state of opening the bottom of the material receiving trough unit 33. More specifically, the third driving unit 31 includes a material receiving cylinder, which is connected to the material dividing plate 32. After the material dividing plate 32 is transversely inserted into the material receiving trough unit 33, the material receiving trough unit 33 is divided into a material receiving trough notch located at the top and a material receiving trough bottom located at the bottom. When the material dividing plate 32 is inserted into the material receiving trough unit 33, the notch of the material receiving trough is not connected to the bottom of the material receiving trough, which is the first state mentioned above, with the material dividing plate 32 between them; and when the material receiving cylinder drives the material dividing plate 32 to move, the material dividing plate leaves the material receiving trough unit 33, and the notch of the material receiving trough is connected to the bottom of the material receiving trough, which is the second state mentioned above. In this way, the copper tubes first pass through the material dividing plate 32 for transition when falling to the bottom of the material receiving trough, so as to avoid a large number of copper tubes from being stacked at the bottom of the material receiving trough.

[0063] The material receiving assembly 3 further includes a second guide rail unit 35 , and the third driving unit 31 , the material dividing plate 32 , the material receiving trough unit 33 and the material receiving trough mounting plate 34 can move together along the second guide rail unit 35 .

In addition, a baffle 334 is also arranged on the side of the receiving trough 331 to prevent the copper tubes from moving out from other positions of the receiving trough 331. That is to say, the copper tubes dropped from the first space enter the corresponding trough bottom through the notch of one receiving trough, and the copper tubes dropped from the second space enter the corresponding trough bottom through the notch of the other receiving trough. When the groove bottom corresponding to the copper tube is replaced, the material discharge driving unit 25 will drive the material discharge plate 231 to move so that the corresponding space is opened.

The fourth drive unit 41 drives the pusher rod 43 through the pusher plate 42, so that the pusher rod 43 enters from the side of the receiving groove 331 away from the conduit 333, so that the copper tube moves along the conduit. Among them, the fourth drive unit 41 includes a double-axis cylinder 411 and a cylinder connecting plate 412, and the double-axis cylinder 411 is installed on the cylinder connecting plate 412.

The fifth drive unit 44 includes a slide cylinder 441 and a slide cylinder mounting plate 442, and the slide cylinder 441 is arranged on the slide cylinder mounting plate 442.

[0068] In the specific use process, the slide cylinder 441 can act on the fourth drive unit 41, the push plate 42, the push rod 43 and the entire material receiving assembly 3. When the material receiving assembly 3 is in place, the double-axis cylinder 411 pushes the push plate 42 and the push rod 43, and the push rod 43 pushes the copper tube in the material receiving groove in the material receiving assembly 3 into place. After the copper tube is pushed into place, the slide cylinder 441 and the double-axis cylinder 411 return to their original positions at the same time.

[0069] The unloading device provided in this embodiment adds a clamping component to solve the problem of copper tube retreat, and clamps the copper tube to prevent it from retreating. When the copper tube is feeding, the clamping block will be lifted up, and the spring will clamp the copper tube in the clamping block to prevent it from retreating. In order to solve the problem of pushing and jamming materials due to overlapping tubes in the receiving trough, a dividing component is added upstream of the receiving component to prevent overlapping tubes from appearing at the pushing position inside the receiving trough. The dividing component adds a dividing plate in the receiving trough, and pushes forward and backward through the cylinder to ensure that only one copper tube falls to the pushing position of the receiving trough. Experiments have shown that after adopting the unloading device provided in this embodiment, the continuous operation time is increased from 1h to 4h. Compared with the traditional structure, the performance is stable and high, and less waste is generated, which ensures the continuous and stable production of the equipment, meets production needs, and enhances its market competitiveness.
