[0038] The embodiment of the present application provides a compressor connecting pipe bending processing device, which solves the problem that the traditional copper pipe can only be processed on copper pipes of one specification during bending processing, otherwise it is difficult to control the bending angle. When bending is required, one of the guide wheels 102 is controlled to move upward, and the compressor connecting pipe is squeezed and bent until the compressor connecting pipe is bent to a suitable angle. When bending is required for compressor connecting pipes of different specifications, it is only necessary to control multiple guide wheels 102 to move at the same time, and the vertical distance between the positioning wheel 101 and the multiple guide wheels 102 is adjusted, so that it is convenient to transmit and bend compressor connecting pipes of other specifications.

[0039] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0040] The embodiment of the invention discloses a compressor connecting pipe bending processing device.

[0046] The driving assembly is arranged inside the press brake body 1, and is used to drive the positioning wheel 101 and the plurality of guide wheels 102 to rotate, thereby driving the compressor connecting pipe to move.

[0047] During use, the end of the compressor connecting pipe is placed between the positioning wheel 101 and the plurality of guide wheels 102, so that the outer side of the compressor connecting pipe fits with the annular groove 103 on the outer sides of the positioning wheel 101 and the plurality of guide wheels 102.

[0048] When pressure bending is required, the extended shaft of one of the cylinders 202 is controlled to move, thereby pushing the first movable seat 201 and the guide wheel 102 to move upward, and the compressor connecting pipe is squeezed and bent until the compressor connecting pipe is bent to a suitable angle, and then the positioning wheel 101 and multiple guide wheels 102 are used to automatically discharge the compressor connecting pipe. When pressure bending is required for compressor connecting pipes of different specifications, it is only necessary to control the extended shafts of multiple cylinders 202 to move at the same time, so that multiple first movable seats 201 and multiple guide wheels 102 move at the same time, and the vertical distance between the positioning wheel 101 and the multiple guide wheels 102 is adjusted, which facilitates the transmission and pressure bending of compressor connecting pipes of other specifications.

[0049] Furthermore, the guide wheel 102 is provided with a first positioning groove 203 which passes through from front to back, and a plurality of first positioning blocks are fixedly connected to the outer side of the transmission shaft 2.
