a material receiving plate 521 is arranged on the material seat 520 and used for bearing the metal pipe fitting sliding out of the second push plate 513; the second pressure sensor 522 is arranged on the material receiving plate 521 and used for detecting a pressure value borne by the material receiving plate 521; the material seat 520 is further provided with a fifth hydraulic cylinder 523, which is used for driving the material receiving plate 521 to move in the vertical direction, so as to convey the metal pipe fittings on the material receiving plate 521 upwards to the middle positions of the first chuck 310 and the second chuck 320, or convey the metal pipe fittings dropped from the first chuck 310 and the second chuck 320 downwards; and a sixth hydraulic cylinder 524 for pushing out the metal pipe processed on the receiving plate 521 and transferring the metal pipe to a discharge box, wherein the fourth hydraulic cylinder 514, the fifth hydraulic cylinder 523, and the sixth hydraulic cylinder 524 are controlled by the controller 370.

In the technical scheme, for feeding, most of the existing feeding devices are realized by adopting inclined sliding grooves, metal pipe fittings are sequentially placed into the sliding grooves and sequentially flow to the clamping assemblies 300 under the action of gravity, and the method has some problems, such as large size of the whole equipment due to long sliding grooves, occupation of a large amount of space, and inconvenience caused by manual alignment of the metal pipe fittings between the first clamping head 310 and the second clamping head 320; therefore, the automatic feeding and discharging device improves feeding, converts the traditional conveying along the horizontal direction into the conveying along the vertical direction, not only can realize automatic feeding and discharging, but also can reduce the volume of the whole device and reduce the occupied space.

The material box 510 is a box body for bearing metal pipe fittings, workers only need to place the metal pipe fittings in the material box 510 at one time, wherein the metal pipe fittings are placed horizontally, the stacking height of the metal pipe fittings is between the first push plate 511 and the guide plate 512, when loading is performed, because the first push plate 511, the second push plate 513 and the guide plate 512 are all provided with inclined guide inclined planes, after the metal pipe fittings are placed in the material box 510, the metal pipe fittings are embedded in the guide inclined planes of the first push plate 511, when the fourth hydraulic cylinder 514 is started, the metal pipe fittings on the first push plate 511 move upwards along the side walls of the guide plate 512, when the first push plate 511 is gradually higher than the guide plate 512, the metal pipe fittings on the first push plate 511 flow towards the guide plate 512 and are limited by the second push plate 513, after the fourth hydraulic cylinder 514 drives the first push plate 511 and the second push plate 513 to reset, the metal pipe fittings on the guide plate 512 flow towards the second push plate 513 and are limited by the inner wall 514 of the material box 510, and after the fourth hydraulic cylinder drives the first push plate 511 and the second push plate 513 to move upwards, the metal pipe fittings on the second push plate 512 and the guide plate 521 are connected to the material seat of the metal pipe fittings 521; after the second pressure sensor 522 detects a pressure value, which indicates that the metal pipe falls onto the receiving plate 521, the controller 370 controls the fifth hydraulic cylinder 523 to operate, so that the receiving plate 521 and the metal pipe thereon move upwards and move between the first chuck 310 and the second chuck 320, thereby realizing the loading.

In the feeding process, when the first pushing plate 511 moves down to the lowest point, in order to enable the metal pipe fitting at the bottom layer in the material box 510 to smoothly flow to the guiding inclined plane of the first pushing plate 511, for this reason, a limiting plate is arranged at the bottom of the material box 510, the limiting plate is horizontally arranged, when the first pushing plate 511 moves down to the lowest point, the uppermost end of the guiding inclined plane of the first pushing plate 511 is flush with the limiting plate, the upper end surface of the limiting plate is arranged in an inclined shape, and the inclined direction of the limiting plate is consistent with the inclined direction of the guiding inclined plane of the first pushing plate 511.

After working for a period of time, it is found that two metal pipes are easily stacked on the first push plate 511, so that two metal pipes flow to the second push plate 513 through the guide plate 512 and finally flow to the material receiving plate 521 at one time, which is a problem because the two metal pipes are stacked up and down and then stably move during the upward movement of the first push plate 511, for this reason, a plurality of protrusions 5121 are uniformly distributed on the sidewall of the guide plate 512, and during the upward movement of the first push plate 511, the metal pipes can move on the protrusions 5121, and because the metal pipe below the first push plate 511 is blocked, the metal pipe below the first push plate 511 cannot be separated from the first push plate 511, and the metal pipe above the metal pipe which is not blocked can be separated from the first push plate 511 under the action of the protrusions 5121, which is very practical.

To connecing flitch 521, can be the concave arc surface with its up end setting to carry on spacingly to metal pipe spare, still be provided with the baffle 525 that is located the both sides of connecing flitch 521 on the material seat 520, when in order to avoid metal pipe spare to slide down to connecing flitch 521 on, because of the speed is too fast, lead to metal pipe spare to break away from and connect flitch 521, consequently metal pipe spare sets up baffle 525 and comes to carry on spacingly to metal pipe spare.

Certainly, after the metal pipe fitting is machined, unloading is needed, and a sixth hydraulic cylinder 524 is further provided for the invention, after the metal pipe fitting is machined, and after the sliding seat 120 has moved to the original position, that is, after the sliding seat is reset, the controller 370 controls the second hydraulic cylinder 330 and the third hydraulic cylinder 340 to work, so that the first chuck 310 and the second chuck 320 loosen the metal pipe fitting, the loosened metal pipe fitting directly falls on the material receiving plate 521, after the pressure sensor on the material receiving plate 521 detects the pressure value again, the fifth hydraulic cylinder 523 drives the material receiving plate 521 to reset, after the reset point is reached, the push plate on the piston rod of the sixth hydraulic cylinder 524 pushes out the metal pipe fitting on the material receiving plate 521, the pushed metal pipe fitting directly flows to the rear discharge chute, and then the sixth hydraulic cylinder 524 resets, which is very convenient, so that automatic unloading is achieved.

As shown in fig. 4 and 6, in the present embodiment, it is optimized that the sliding seat 120 is provided with a first displacement sensor 121 for detecting a distance between the first displacement sensor and the upper end surface of the material receiving plate 521 and sending information to the controller 370; the second displacement sensor 122 is used for detecting the distance between the second displacement sensor and the top of the metal pipe fitting on the material receiving plate 521, and sending information to the controller 370; the controller 370 controls the upward movement of the fifth hydraulic cylinder 523 according to the information sent by the first displacement sensor 121 and the second displacement sensor 122, so that the metal pipe on the material receiving plate 521 is aligned with the opening on the inner cylinder 222.

In the technical scheme, during processing, for metal pipes with different outer diameters, corresponding programs need to be adjusted, that is, the elongation of the fifth hydraulic cylinder 523 needs to be adjusted, so that the metal pipes can be aligned, however, under the conditions of a large number of batches and a small number of batches, the program needs to be adjusted at any time, which is very troublesome.
