Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment and relates to an air outlet pipe end forming machine. Background Art

[0002] When processing the end of the arc-shaped air outlet pipe, four steps are required: loading, clamping, processing and discharging. At present, when a shorter arc-shaped air outlet pipe needs to be processed, after the clamp in the prior art clamps the air outlet pipe, less of the clamping groove is exposed at the end of the air outlet pipe, which makes it impossible to process the pipe end, and the air outlet pipe will slip in the groove during processing.

[0003] In order to overcome the shortcomings of the prior art, people have proposed various solutions through continuous exploration. For example, a Chinese patent discloses a pipe bending clamp [application number: 201320035971.0], which includes two mirror-symmetrical pipe bending clamps, each of which includes a clamping body, characterized in that each of the pipe bending clamps also includes: a compressible assembly body, the clamping body includes a step surface at the top and a side wall adjacent to the step surface, the assembly body is fixed on the step surface, and the side wall of the assembly body is flush with the side wall of the clamping body on the corresponding side; a clamping groove integrally formed in the side wall of the assembly body and the clamping body on the corresponding side and used to embed the pipe bending. The pipe bending clamp provided by the utility model leaves room for the pipe bending to expand during its assembly, and effectively prevents the pipe bending from slipping in the clamp by means of the anti-slip body embedded in the clamping body, which well protects the pipe bending and avoids damage during the assembly process, but it also has the above-mentioned disadvantages.

[0062] The working principle of the present invention is as follows: the clamping groove 8 formed by the combination of the upper clamping die 6 and the lower clamping die 7 can clamp the air outlet pipe. When processing one end of the air outlet pipe, the adjustable processing limit mechanism 10 corresponding to the other end of the air outlet pipe can push the unprocessed end of the air outlet pipe to move toward the processing end, so that the processing end can protrude from the clamping groove to facilitate processing at the processing end, and the adjustable processing limit mechanism 10 can abut against the unprocessed end to prevent processing errors caused by sliding of the air outlet pipe when processing the air outlet pipe; when the driver fixing seat 11 is connected to the machine base 1, the mold opening driver 12 can drive the lower clamping die 7 to move to open or close the mold, and when the driver fixing seat 11 is fixed on the machine base 1 through a plurality of support columns, the mold opening driver 12 can drive the upper clamping die 6 to move from When opening or closing the mold, the linear drive 16 drives the upper mold 18 and the auxiliary clamp 19 to move upward, and an air outlet pipe can be added to the clamping groove after the mold is opened. After closing the mold, when processing one end of the air outlet pipe, the linear drive 16 corresponding to the unprocessed end of the air outlet pipe can drive the upper mold 18 and the auxiliary clamp 19 to move downward. When the auxiliary clamp 19 moves downward, the inclined adjustment surface 22 on the air outlet pipe adjustment plate 21 can push the unprocessed end of the air outlet pipe to move toward the processed end, so that the processed end can protrude from the clamping groove to facilitate the processing of the processing end, and the air outlet pipe adjustment plate 21 can abut against the unprocessed end to prevent processing errors caused by the sliding of the air outlet pipe when processing the air outlet pipe; rotating the fine-tuning screw 24 can drive the air outlet pipe adjustment plate 21 to move closer to or away from the clamp The clamping groove can make the air outlet pipe adjustment plate 21 adapt to air outlet pipes of different sizes; when processing a shorter air outlet pipe, the length of the clamping groove is shorter due to processing requirements. When loading, when the air outlet pipe is placed in the clamping groove on the lower clamping die, the contact area between the air outlet pipe and the clamping groove is small, and it is easy to fall off during feeding. The tray driver 27 in the lifting tray assembly 26 corresponding to the openings on both sides of the clamping groove can drive the air outlet pipe tray 29 to rise to be flush with the bottom of the clamping groove, thereby preventing the air outlet pipe from falling off during feeding; at least one of the air outlet pipe trays 29 in the two lifting tray assemblies 26 is provided with an arc groove 30 on the top to limit the air outlet pipe; the vibration plate 34 can vibrate the air outlet pipe from the discharge port to the straight vibration channel 35, and then pass through the straight vibration channel 3 5, the vibration will vibrate the outlet pipe to the outlet of the straight vibration channel 35, and the channel baffles 36 are arranged on both sides of the straight vibration channel 35, and the cross section of the channel baffles 36 on at least one side is L-shaped, which can prevent the outlet pipe from falling from the side or upper side of the straight vibration channel 35; the slider rail structure can limit the movement of the slider lifting plate 41, the feeding driver 43 can drive the rotary guide plate 44 and the two-claw driver 46 on the rotary guide plate 44 to move to the outlet of the straight vibration channel 35, and the lifting driver 40 can drive the slider lifting plate 41 to descend, so as to cooperate with the two-claw driver 46 to clamp the outlet pipe on the straight vibration channel 35 through two clamping claws, and then the outlet pipe is transported to the feeding mechanism through the cooperation of the feeding driver 43, the lifting driver 40 and the two-claw driver 46;When the feeding driver 43 drives the rotary guide plate 44 to move to the point where the limit screw 50 abuts against one side of the long strip limit groove 49, the limit screw 50 can limit the limit bar to stop its movement, and the feeding driver 43 can continue to drive the rotary guide plate 44 to move so that the rotary guide plate 44 can rotate around the connection between the clamping rocker arm 47 and the limit bar 48, thereby adjusting the angle of the air outlet pipe to make it compatible with the clamping groove; the two-claw driver 46 can put the clamped air outlet pipe into the storage groove on the storage plate 65, and multiple air outlet pipes can be placed in the storage groove, and the air outlet pipe can enter the feed groove 64 from the storage groove, and the material receiving reset plate 60 can block the air outlet pipe The feeding screw 52 is connected to an external motor, which can drive the feeding screw 52 to rotate, thereby driving the feeding slider 54 to slide along the feeding screw 52 toward the clamping groove. The movement of the feeding slider 54 can simultaneously move the material receiving reset plate 60 and the feeding push plate 63 toward the clamping groove through the feeding rod guide seat 57 and the slider connecting plate 62. When the material receiving reset plate 60 moves to the abutting step 61 on the lower side and abuts against the feeding cylinder seat 51 near the clamping groove 8, the material receiving reset plate 60 stops moving forward and the feeding push plate 63 continues to move forward. When the material receiving reset plate 60 is completely separated from the feeding groove 64, the feeding groove 6 The outlet pipe in 4 just falls into the clamping groove and the top of the outlet pipe tray 29 is flush with the bottom of the clamping groove at this time; the discharge lifting driver 67 can drive the discharge slide seat 71 and the horizontal discharge driver 72 connected to the discharge slide seat 71 to move until the discharge two-claw driver 75 is flush with the outlet pipe, the limiting round rod 69 can limit the discharge slide seat 71, and the horizontal discharge driver 72 can drive the discharge slide plate 73 and the discharge two-claw driver 75 connected to the discharge slide plate 73 to move toward the clamping groove, so as to cooperate with the discharge two-claw driver 75 to clamp the processed outlet pipe through two clamping claws, and then drive the discharge lifting driver 67 to The air outlet pipe moves up and down to separate from the clamping groove, and finally the air outlet pipe is sent to the discharge slide 76 through the cooperation of the discharge lifting driver 67, the horizontal discharge driver 72 and the discharge two-claw driver 75, and finally the air outlet pipe falls into the storage hopper through the discharge slide 76 and the discharge groove 77; the servo slide 80 includes a linear driver and a slide rail slide, the linear driver can drive the slide and the boring and milling head assembly 81 on the slide to move along the slide rail toward the clamping groove, the boring and milling head assembly 81 includes a driver, the driver can drive the shrinking die or the plane tool holder 83 to move to process and shape the pipe mouth of the air outlet pipe, and the plane tool holder 83 can be installed with a tool. ;
