Abstract
Description
Technical Field
[0001] This invention relates to the field of air conditioning pipe processing technology, specifically to a processing equipment for ultra-long automotive air conditioning pipes and its usage method. Background Technology
[0002] Most existing air conditioning pipe processing equipment includes a pipe bending device. After the pipe material is heated and softened, the bending device bends the pipe material into a set curvature. Since the air conditioning pipe needs to be installed inside the frame and the internal space of the frame is limited, the air conditioning pipe usually needs to be bent 1 to 2 times to adapt to the internal space of the frame.
[0003] Existing bending equipment processes pipes that require two bends separately. Since the bending device can only bend the pipe once, when bending again, the part of the pipe that needs to be bent a second time is either manually dragged to the bending station or an additional bending device is installed. These methods cannot form the pipe in one go, affecting the processing accuracy.
[0004] Therefore, it is necessary to provide a processing equipment for ultra-long automotive air conditioning pipes and a method for using them to solve the above problems. Summary of the Invention
[0005] Based on the aforementioned problems in the existing technology, the purpose of this invention is to provide a processing equipment for ultra-long automotive air conditioning pipes and a method for using them.
[0006] The technical solution adopted by this invention to solve its technical problem is: a processing equipment for ultra-long automotive air conditioning pipes and its usage method, comprising a machine body, the machine body including a pipe bending mechanism, the pipe bending mechanism including a fixed frame, a lifting cylinder mounted on the base of the fixed frame, a lifting block fixedly mounted on the output end of the lifting cylinder, a bending component provided above the lifting block, one end of the lifting block bent downwards, grooves provided on the outer walls of the bending component adjacent to the lifting block, a pipe bending sleeve fixedly mounted on one end of the bending component, the outer wall of the pipe bending sleeve fitting into the groove of the lifting block, guide grooves and lifting grooves symmetrically provided on the panels on both sides of the fixed frame, the guide grooves being located above the lifting grooves, guide rods fixedly mounted on both sides of the lifting block, the guide rods passing through the lifting grooves, an extension rod being installed through the center of the bending component, both ends of the extension rod passing through the guide grooves, and a rotary motor mounted on one end of the extension rod.
[0007] Furthermore, a guide rail is provided on one side of the bending of the lifting block. One end of the guide rail is fixedly connected to the two side panels of the fixing frame. A groove is provided on the outer wall above the guide rail. A transmission component is installed below the guide rail. The transmission component includes a lead screw and a servo motor. The lead screw is fixedly installed on the outer wall below the guide rail. The lead screw is driven by the servo motor installed in a matching manner. A matching slider is installed on the outer wall of the lead screw.
[0008] Furthermore, a shaping component is attached to the top of the guide rail. The bottom sides of the shaping component are fixedly connected to the slider sides of the lead screw. The surface of the shaping component that is attached to the guide rail is arc-shaped. The arc surface of the shaping component has a groove. A sliding rod is installed through the center of the shaping component. Both ends of the sliding rod are equipped with sliding grooves. The two sets of sliding grooves are fixedly connected to the side panels of the fixing frame.
[0009] Furthermore, an operating platform is installed on the side of the fixed frame away from the guide rail. The operating platform is fixedly connected to the outer walls of the two side panels of the fixed frame. A second lead screw transmission assembly is installed at the bottom of the operating platform. The second lead screw transmission assembly includes a second lead screw and a servo motor. The second lead screw is fixedly installed at the bottom of the operating platform and is driven by the servo motor. A matching slider is installed on the outer wall of the second lead screw. A sliding member is sleeved on the outside of the end of the operating platform near the fixed frame. The bottom of the sliding member is fixedly connected to the slider of the second lead screw.
[0010] Furthermore, two sets of pull rods are fixedly installed above the sliding member. The two sets of pull rods are symmetrically arranged. The rod body of the pull rod is bent at a 90-degree angle. One end of the two sets of pull rods is fixedly connected to the sliding member, and the other end is located on both sides above the bent member. A leather sleeve is provided at the end of the two sets of pull rods away from the sliding member. The two ends of the leather sleeve are fixedly connected to the ends of the two sets of pull rods respectively.
[0011] Furthermore, the softened pipe material, heated by the high temperature, enters the guide rail via a conveyor belt until the pipe end reaches the port of the lifting block and stops. At the port of the guide rail away from the fixed frame, there is a pipe clamp that tightens the end of the pipe. At this time, the pipe material passes through the bending sleeve. The rotary motor connected to the bending extension rod is started. The rotary motor drives the bending component to rotate, and the bending sleeve drives the pipe material to bend. The bending angle matches the arc of the groove of the bending component. After the bending component rotates one revolution, the bending sleeve will disengage from the already bent end of the pipe. Then, the second lead screw transmission mechanism is started, and the servo motor matched with the lead screw is started. Through the slider, the sliding component drives the pull rod to move above the operating table. The pull rod drives the sleeve, and the sleeve pulls the bent part of the pipe material. At this time, the clamp is released, and the bent pipe is placed on the operating table for cleaning debris and oil stains.
[0012] Furthermore, when the tube material needs to be bent in two stages, after the end of the tube material is bent, the lead screw drive assembly is activated, the servo motor of lead screw one is activated, and the slider of lead screw one is activated, which drives the shaping part to move to the position where the tube material needs to be bent in two stages. The sliding rod of the shaping part slides in the sliding groove, which can increase the stability of the shaping part. At this time, the lifting cylinder is activated, which lifts the lifting block. The guide rod of the lifting block moves down in the lifting groove. The lifting block drives the bending part to move. The bending part moves through the extension rod with the guide groove as the guide, which drives the tube material to bend. The bent part fits with the groove on the back of the shaping part. Then the tube material after bending is dragged to the operating table.
[0013] The beneficial effects of the present invention are as follows: The processing equipment and method for ultra-long automotive air conditioning pipes provided by the present invention, by setting up a pipe bending mechanism, allows the pipe material to be bent in two sections inside the machine body and formed in one step, while having an automatic material picking function and automatically connecting to the next process.

[0029] In this embodiment, the following steps are performed before the air conditioning pipe enters the unit body 1 and is bent:
[0030] Step one: Inspect the chamfers at both ends of the pipe using a material inspection machine. The material inspection machine takes pictures of the pipe with a camera, transmits the image data to a terminal, and records the length and chamfer angle.
[0031] Step two: Use a chamfering machine to grind the chamfers of the pipe body. The material inspection machine and the chamfering machine are connected by a conveyor belt. The pipe material is transported from the material inspection machine to the processing station of the chamfering machine. Based on the data recorded by the terminal, the chamfer is automatically ground to make the chamfer meet the production requirements.
[0032] Step 3: After the chamfering is completed, the conveyor belt sends the tube to the upsetting machine to upset one end of the tube, and then sends it to the cleaning machine for cleaning.
[0033] Step 4: The pipe material is fed into a high-temperature furnace for heating and softening, and then fed into machine body 1 for bending.
[0034] Example 1: The softened pipe material at high temperature enters the guide rail 8 via a conveyor belt until the end of the pipe material is delivered to the port of the lifting block 6 and stops. At the port of the guide rail 8 away from the fixed frame 2, there is a pipe clamp (not shown in the figure). The clamp will tighten the end of the pipe. At this time, the pipe material passes through the bending sleeve 17. The rotary motor connected to the extension rod of the bending piece 5 is started. The rotary motor drives the bending piece 5 to rotate. The bending sleeve 17 drives the pipe material to bend. The bending angle fits the arc of the groove of the bending piece 5. After the bending piece 5 rotates one revolution, the bending sleeve 17 will disengage from the bent end of the pipe. Then the second lead screw transmission mechanism is started. The servo motor matched with the second lead screw 14 is started. The slider drives the sliding piece 16. The sliding piece 16 drives the pulling rod 12 to move above the operating table 13. The pulling rod 12 drives the leather sleeve 15. The leather sleeve 15 pulls the bent part of the pipe material. At this time, the clamp is released and the bent pipe is placed on the operating table 13 for cleaning debris and oil stains.
[0035] Example 2: When the tube needs to be bent in two sections, after the end of the tube is bent, the lead screw drive assembly is started, the servo motor of lead screw 9 is started, and the slider of lead screw 9 is started, which drives the shaping part 7 to move to the position where the tube needs to be bent in two sections. The sliding rod of the shaping part 7 slides in the sliding groove 3, which can increase the stability of the shaping part 7. At this time, the lifting cylinder 4 is started, lifting the lifting block 6. The guide rod of the lifting block 6 moves down in the lifting groove 11. The lifting block 6 drives the bending part 5 to move. The bending part 5 moves through the extension rod with the guide groove 10 as the guide, which drives the tube to bend. The bent part fits with the rear groove of the shaping part 7. Then the tube after bending is dragged to the operating table 13.
[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention.
