Description

Technical Field

[0001] The utility model relates to the technical field of pipe end forming machines, in particular to a blanking component of a pipe end forming machine. Background Art

[0002] The pipe end forming machine is a highly efficient pipe processing equipment. During the processing of chamfering, flanging, shrinking and expanding pipe fittings, the cut batches of pipe fittings need to be placed into the pipe segment forming machine one by one in an orderly manner. The existing pipe end forming machine uses the weight of the pipe fittings and starts the clamping assembly to arrange the pipe fittings along the inclined surface for orderly feeding.

[0003] For example, the Chinese patent application number CN201811471511.6 discloses a pipe end forming machine, comprising a machine body, a processing head driven by a driving device slidably mounted on the machine body, a support frame provided on one side of the execution end of the processing head, and a pipe guide mechanism inclined toward the processing head provided on the support frame; compared with the traditional method, it does not require manual intervention, greatly improves operational safety, and greatly reduces the labor intensity of the staff; at the same time, effectively improves work efficiency. However, in order to ensure that the length of the pipe fittings is consistent and the pipe ends are neat, the cutting knife needs to be oiled. The oil applied will adhere to the surface of the pipe fittings. When the material is cut out of the inclined surface on the support frame, the oil between the pipe fittings reduces the friction between each other, and the material often deflects or gets stuck due to the working vibration of the pipe end forming machine. Moreover, when there is too much oil attached to the surface, it will also affect the clamping effect of the pipe fittings during the pipe end forming process. Utility Model Content

[0034] The first aspect of the present invention provides a blanking assembly for a tube end forming machine, such as Figure 1-6 As shown, it includes a blanking box 1 arranged on the body of the tube end forming machine, a blanking guide groove 2 is provided at the upper end of the blanking box 1, the blanking guide groove 2 is hinged to the blanking box 1, and an air nozzle 3 is opened in the middle of the blanking guide groove 2. The blanking assembly also includes:

[0035] There is at least one rotating frame 4, which is rotatably mounted in the material discharge box 1 and is placed on the side of the material discharge guide groove 2;

[0036] A plurality of toggle heads 5 are provided, and the plurality of toggle heads 5 are intermittently mounted on the side ends of the rotating frame 4;

[0037] A leveling roller 6 is slidably arranged in the unloading guide groove 2 through a tension spring, and a shifting ball 7 that cooperates with the shifting head 5 is installed at both ends of the leveling roller 6;

[0038] A driving mechanism for driving the rotating frame 4 to rotate.

[0039] In this embodiment, the driving mechanism includes:

[0040] A driving motor 8 is installed at the lower part of the blanking box 1, and a driving wheel 9 is installed at the output end of the driving motor 8;

[0041] The rotating drum 10 is a hollow structure. The rotating frame 4 is mounted on the rotating drum 10. A driven wheel 11 is mounted on the outer side of the rotating drum 10. The driven wheel 11 is connected to the driving wheel 9 via a synchronous belt 12.

[0042] An air pump 13 is installed on a side end of the discharge box 1 through a mounting bracket, and an air jet 17 of the air pump 13 is connected to the rotating drum 10 .

[0043] In this embodiment, a cam 14 is further mounted on the rotating drum 10 , and the outer edge of the cam 14 abuts against the lower end surface of the discharge guide groove 2 .

[0044] In this embodiment, a mounting groove 15 is provided in the middle of the rotating drum 10, and the cam 14 is fixedly installed in the mounting groove 15. A ventilation opening 16 connected to the inner cavity of the rotating drum 10 is provided in the mounting groove 15, and an air jet 17 is provided on the cam 14, and the jet path of the air jet 17 covers the air jet 3.

[0045] In this embodiment, when in use, the pipes are sequentially placed into the upper end of the material discharge guide groove 2. Under the action of their own weight, the pipes are automatically arranged on the material discharge guide groove 2. The pipe at the lower end abuts against the leveling roller 6. The driving motor 8 is started so that its output end drives the driving wheel 9 to rotate. The synchronous belt 12 and the driven wheel 11 drive the rotating drum 10 and the rotating frame 4 to rotate synchronously. The rotation of the rotating frame 4 drives the multiple toggling heads 5 thereon to follow.

[0046] During the following movement of the plurality of toggle heads 5, the toggle balls 7 that match their rotation paths are pushed to move toward the lower end of the feed guide groove 2. Combined with the elastic tension of the tension springs on both sides of the feed guide groove 2, the leveling rollers 6 drive the pipes in the feed guide groove 2 to slide back and forth. In the state of the pipes rolling and sliding, they are arranged flatly to avoid deflection or jamming.

[0047] At the same time, the rotation of the drum 10 also drives the cam 14 to rotate synchronously, thereby pushing the upper unloading guide groove 2 to perform a small angle reciprocating rotation, and providing high-pressure airflow into the drum 10 through the air pump 13;

[0048] When the small-diameter outer edge of the cam 14 rotates to face the air nozzle 3, air is ejected from the vent opening 16 and the air nozzle 17 on the cam 14, and directly sprayed onto the surface of the pipe on the lower guide groove 2 through the air nozzle 3. At this time, for the pipe in the rolling and sliding state, its surface will be completely exposed to the air flow range, so as to blow off the oil attached to the surface of the pipe in time, avoiding the influence of too much oil on the clamping effect of the pipe during the pipe end forming process.

[0049] In this embodiment, if Figure 1 As shown, the inner side of the blanking box 1 is in the shape of an oblique end face and cooperates with the lower end of the blanking guide groove 2. The pipe fittings after blanking automatically enter the pipe end forming machine below for forming processing.

[0050] In this embodiment, if Figure 1 、 Figure 3As shown, there are two rotating frames 4, which are respectively arranged on both sides of the blanking guide groove 2. The moving heads 5 on the two rotating frames 4 are staggered in the horizontal direction, so that under the premise of stable oil-clearing airflow, the reciprocating action frequency of the leveling roller 6 is higher, further improving the orderly arrangement effect of the pipe fittings in the blanking guide groove 2.

[0051] In this embodiment, if Figure 1 、 Figure 2 As shown, a baffle plate 18 that can be raised and lowered is provided in the unloading guide groove 2. The installation height of the baffle plate 18 in the unloading guide groove 2 is not lower than the leveling roller 6. The appropriate lifting and lowering adjustment of the baffle plate 18, combined with the high-frequency leveling action, can adapt to pipes of different diameters.
