Description

TECHNICAL FIELD

[0002] The processing of engine oil pipes generally comprises the following steps: cutting the oil pipe into a required length, bending, welding, surface treatment and performance testing. When the oil pipe is bent, a suitable bending mode is selected according to the material properties of the oil pipe, and the bending mode is realized by cold bending forming, hot bending forming and numerical control pipe bending. However, the most commonly used material is metal alloy, and a pipe bending machine is usually used for bending, which is suitable for batch production. The current pipe bending machine can realize automatic continuous multi-bending once forming under system setting, and can also be bent at three-dimensional multi-angles without manual multi-angle adjustment and repeated clamping positioning as required by the traditional pipe bending machine.

It should be noted that the drawings provided in the following embodiments only schematically illustrate the basic concept of the present application, and the following embodiments and features in the embodiments can be combined with each other without conflict.

[0041] Example 1: as Figures 1-6 , Figure 11As shown in the figure, the processing equipment for engine cooling oil pipe includes two support plates 1, four support columns 2, a feeding hopper 3, a feeding pipe 4 and a rotating seat 5, the feeding pipe 4 is fixedly arranged through the two support plates 1, the feeding opening at the bottom end of the feeding hopper 3 is in through communication with the top of the feeding pipe 4, for sequentially feeding the oil pipes one by one in the form of free falling into the feeding pipe 4, the four support columns 2 are symmetrically fixedly connected at the bottom of the two sides of the feeding hopper 3, for fixing and supporting the whole feeding hopper 3 at the top of the feeding pipe 4, a set of feeding mechanisms are arranged in the feeding pipe 4, for pushing the oil pipes falling into the feeding pipe 4 outward to the bending mechanism for bending, a mounting slot 41 is formed at the bottom of the feeding pipe 4 close to the end of the oil pipe feeding out, the rotating seat 5 is rotatably arranged in the mounting slot 41, a through hole 51 for guiding the oil pipe to pass out is formed in the rotating seat 5, a set of clamping mechanisms are arranged in the rotating seat 5 and are used in cooperation with the feeding mechanisms, so that the oil pipe can be automatically clamped moderately during the feeding process, and one side of one of the support plates 1 is provided with a driving mechanism for driving the rotating seat 5 to rotate, so as to freely adjust the bending angle of the oil pipe.

[0042] The present application can be used in the field of processing equipment for engine cooling oil pipe, and can also be applied to other fields of the present application.

[0043] Embodiment 2: The present embodiment is a further improvement on the previous embodiment: as shown in the figure, Figures 1-4 , Figure 11 As shown in the figure, the feeding mechanism includes a push block 11 slidingly fitted on the inner wall of the bottom of the feeding pipe 4, the side of the push block 11 away from the outlet end of the feeding pipe 4 is fixedly connected with a blocking strip 7, and the top of the blocking strip 7 is flush with the top of the push block 11, and the bottom of the feeding pipe 4 is provided with a driving part for driving the push block 11 to move. Figure 3As shown, first, the oil pipe to be processed is placed in the lower hopper 3, and the oil pipes are stacked in a vertical manner in the lower hopper 3 and fall one by one. It should be noted that the lower hopper 3 can be made in the shape of a bucket or directly in the shape of a rectangle matching the length of the oil pipe. The bucket shape allows for the storage of more oil pipes at one time, but a vibration motor needs to be configured to vibrate the lower hopper 3 to prevent clogging. The rectangular shape cannot store too many oil pipes at one time, but it can complete automatic feeding without a vibration motor. The specific type of lower hopper 3 can be set according to the specific scene and use requirements. When the push block 11 is not located below the lower hopper 3, the lowermost oil pipe falls into the conveying pipe 4 from the bottom outlet, and the upper oil pipes fall in turn, and the second last oil pipe is still attached to the top of the lowermost oil pipe and is still located in the lower hopper 3. It should also be noted that since the oil pipe is circular, in order to prevent the lowermost oil pipe from rolling after falling into the conveying pipe 4 due to the pressure of the upper oil pipe, a limiting structure can be provided inside the conveying pipe 4 to prevent rolling, which can be provided on the inner wall of the conveying pipe 4 or on the push block 11. For those skilled in the art, this structure is a conventional technical means and is not limited in detail. Then the push block 11 and the stop bar 7 are moved by the driving member, and when the push block 11 contacts one end of the lowermost oil pipe, it will push it to move to the outlet end of the conveying pipe 4 and send it out of the conveying pipe 4. Finally, the bending mechanism is bent. During the movement of the push block 11, the top of the stop bar 7 will contact and support the bottom of the second last oil pipe to prevent the oil pipe in the lower hopper 3 from falling into the conveying pipe 4. After the push block 11 pushes and processes the oil pipe, the push block 11 and the stop bar 7 are moved in the opposite direction by the driving member. At this time, the push block 11 moves out of the lower position of the lower hopper 3 and no longer supports the oil pipe in the lower hopper 3. At this time, the lowermost oil pipe in the lower hopper 3 automatically falls into the conveying pipe 4, and the upper oil pipes fall freely in turn. This reciprocating operation achieves the effect of automatic feeding.

[0044] In one aspect of the embodiment, the driving member comprises a first vertical plate 6 and a second vertical plate 38 symmetrically fixedly connected to the outer wall of the bottom of the feeding hopper 3, a same lead screw 8 rotationally connected between the first vertical plate 6 and the second vertical plate 38, a lead screw motor 12 fixedly connected to one side of the first vertical plate 6, and an output shaft of the lead screw motor 12 rotationally penetrating through one side of the first vertical plate 6 and fixedly connected to one end of the lead screw 8, a bottom of the blocking strip 7 fixedly connected with a supporting block 9, the bottom of the supporting block 9 extending to below the bottom of the conveying pipe 4 and integrally formed with a nut block 10, the nut block 10 threadedly sleeved on the lead screw 8, and a strip-shaped hole 42 provided in the bottom of the conveying pipe 4 and slidably penetrated by the supporting block 9. Starting the lead screw motor 12 drives the lead screw 8 to rotate, which drives the nut block 10 to move, and at the same time drives the supporting block 9 to slide horizontally in the strip-shaped hole 42, thereby driving the blocking strip 7 to move, so as to drive the push block 11 to move, realizing the pushing of the oil pipe and the supporting effect of the oil pipe in the feeding hopper 3.

When the lead screw motor 12 is started to drive the push block 11 to push the oil pipe to move outward in the conveying pipe 4, the end of the oil pipe away from the push block 11 sequentially penetrates out of the connecting ring 14 and the through hole 51 and extends outward from one end of the conveying pipe 4. Since the oil pipe moves along the bottom wall of the conveying pipe 4, and the through hole 51 on the rotating seat 5 is eccentrically arranged with the internal space of the conveying pipe 4, as shown in Figure 3As shown, further enable the oil pipe from the normal from the hole 51, and play a guiding effect of push.

Through the rubber pad 22 not only can play the effect of protection to the surface of the oil pipe, avoid extrusion wear in the process of pushing, but also through the extrusion clamping of the rubber pad 22 to the oil pipe, can effectively increase the friction between the clamping, in the case of not need to over clamp also can achieve moderate clamping.

[0047] Embodiment 4: this embodiment as the further improvement of the last embodiment: as shown in Figures 1-11 As shown, the installation slot 41 close to the side wall of the push block 11 above arc equally spaced multiple chute 43, multiple chute 43 are all connected with the slide rod 29, multiple slide rod 29 one end are all outwardly extending and fixedly connected with the fixed block 28, multiple fixed block 28 of the inner side surface fixedly connected with the same push plate 27, and the push plate 27 close to the side of the rotating seat 5 and the connecting ring 14 away from the side of the rotating seat 5 contact, one side of the push plate 27 is provided with a through hole 271 matched with the oil pipe and multiple guide rod 17. The oil pipe in the process of pushing, its one end can first pass through the through hole 271, then pass through the connecting ring 14, finally from the hole 51. And in the process of pushing, can make the push plate 27 move a small distance, and push the connecting ring 14 also move a small distance, make the side of the connecting ring 14 and the side of the rotating seat 5 contact, further realize the moderate clamping of the oil pipe. The side of the push plate 27 extends to the bottom of the material conveying pipe 4 below and is fixedly connected with the connecting rod 32, one end of the connecting rod 32 penetrates through one side of the second vertical plate 38 and is fixedly connected with the movable plate 33, the outer wall of one side of the connecting rod 32 is slidably sleeved with the sliding sleeve 35, one end of the sliding sleeve 35 is fixedly connected with the second vertical plate 38, and a second spring 34 is fixedly connected between one end of the sliding sleeve 35 and one side of the movable plate 33, and the second spring 34 is sleeved on the outer wall of one side of the connecting rod 32. When the movable plate 33 moves, it can move in the sliding sleeve 35 and press the second spring 34, and at the same time it can drive the push plate 27 to move synchronously, realize the pushing of the connecting ring 14.

When the lead screw motor 12 is started to drive the lead screw 8 to rotate, the nut block 10 can be driven to move, which not only can drive the push block 11 to push the oil pipe, but also can drive the L-shaped pressing rod 25 to move at the same time. When one end of the oil pipe is pushed close to the outlet end of the feeding pipe 4, it has already passed through the perforation 51, at this time, the L-shaped pressing rod 25 abuts against the protrusion 31. With the continuous movement of the nut block 10, the oil pipe is continuously pushed out, at this time, the L-shaped pressing rod 25 will rotate and move by abutting against the protrusion 31, drive the fixed ring 30 to rotate, and further drive the rotating rod 26 to rotate. With the continuous movement of the L-shaped pressing rod 25, the protrusion 31 will not rotate after rotating to the maximum angle, but will be pressed on the bottom by the L-shaped pressing rod 25, so that the rotating rod 26 will only rotate by a certain angle. At the same time, the rotating rod 26 will drive the two cams 36 to rotate by a certain angle, and drive the movable plate 33 to move a small distance, so as to realize the movement of the push plate 27 by a small distance through the movement of the connecting rod 32, and further realize the effect of automatic moderate clamping in the process of pushing the oil pipe.

When the L-shaped pressing rod 25 is separated from the protrusion 31, it will drive the rotating rod 26 to rotate and reset under the elastic force of the torsional spring 39, so as to drive the fixed ring 30 and the two cams 36 to rotate and reset, and the connecting ring 14 will also move and reset under the elastic force of the first spring 21, and the push plate 27 will also move and reset under the elastic force of the second spring 34, so as to realize the effect of contacting and clamping the processed oil pipe, which is convenient for taking down. The previously processed oil pipe can also be pushed out by pushing the next oil pipe, so as to realize the effect of automatic unloading.

When one end of the oil pipe is pushed through the perforation 51 and sent out from the outlet end of the delivery pipe 4, the oil pipe is in a state of being moderately clamped. When the oil pipe needs to be bent at an angle, the servo motor 23 can be started to drive the rotating seat 5 to rotate through the engagement movement of the transmission gear 24 and the outer tooth ring 13, thereby driving the oil pipe to rotate and achieving the effect of adjusting the angle. Since the push plate 27 directly pushes against one side of the connecting ring 14, and the rotating seat 5 drives the connecting ring 14 to rotate synchronously when rotating, the normal rotation of the rotating seat 5 is not affected during clamping of the oil pipe. Moreover, the through hole 271 is arranged on the push plate 27, which not only facilitates the passage of the oil pipe, but also enables the plurality of guide rods 17 to rotate and move in the through hole 271 when the rotating seat 5 rotates, without causing obstruction.

[0050] In one aspect of the embodiment, a plurality of balls 37 are circumferentially arranged and embedded in the push plate 27 close to one side of the connecting ring 14 around the through hole 271, and the plurality of balls 37 are in contact with one side of the connecting ring 14. When the connecting ring 14 rotates with the rotating seat 5, it can rotate in contact with one side of the push plate 27. At this time, by arranging the plurality of balls 37, the rotating friction of the connecting ring 14 can be reduced when the push plate 27 pushes and drives the connecting ring 14, so that the connecting ring 14 and the rotating seat 5 can be better adjusted.
