Description

Technical Field

[0001] This utility model relates to the field of automated equipment technology, and in particular to an oil pipe joint bending device. Background Technology

[0002] The fisheye connectors currently used on motorcycles, ATVs, off-road vehicles, electric vehicles, bicycles and other similar vehicles are all a type of oil pipe connector. At the same time, the existing oil pipe connectors vary depending on the vehicle design and layout requirements, and are mainly divided into straight connectors and bent connectors.

[0003] Straight connectors are suitable for situations where the intake pipe direction or angle does not need to be changed, allowing the carburetor to be directly aligned with the intake pipe. Bent connectors, on the other hand, are suitable for situations where the intake pipe direction or angle needs to be changed, that is, the position of the intake pipe can be adjusted by bending or angling to adapt to different motorcycle designs or layouts (for example, in some motorcycle designs, the intake pipe may need to enter the carburetor from different angles, and bent connectors can provide greater flexibility and adaptability).

[0004] Existing curved oil pipe fittings commonly have angles of 28° or 45° lateral deviation, or 28° or 45° positive. The current forming process for curved oil pipe fittings generally involves: 1. forming the fitting blank and core separately; 2. riveting the formed fitting blank and core together; 3. bending the riveted fitting at the required angle at both ends of the fisheye and core (i.e., to ensure the convenience of separate forming in the early stage and subsequent riveting process, the straight fitting is usually produced first, and then the angle is bent).

[0005] Existing methods for bending tubing fittings typically involve manual labor. This involves placing the fitting on a specialized fixture, which clamps one end of the fitting. An operator then stands to one side of the fixture and uses a sleeve-like tool to bend the fitting at a predetermined angle. However, manual bending is inefficient and unsuitable for mass production. Furthermore, controlling the bending angle manually is difficult, resulting in a high defect rate for manually formed bent tubing fittings. Summary of the Invention

[0006] In view of the above shortcomings, this utility model provides a bending device that can greatly improve the bending efficiency of oil pipe joints while ensuring the quality of finished products.

[0007] To achieve the above objectives, this utility model employs an oil pipe joint bending device, comprising an operating table, a control center, a feeding mechanism, a feeding track connected to the outlet of the feeding mechanism, a workpiece clamping area distributed on the outlet end of the feeding track, and a workpiece bending mechanism distributed on one side of the workpiece clamping area. The workpiece clamping area includes a rotating area that is limited to the operating table and rotates, and a positioning area distributed on one side of the rotating area. The rotating area has several workpiece placement areas. The positioning area is adjacent to the rotating area, and through the positioning area, one or more workpieces to be bent in the several workpiece placement areas on the workpiece clamping area are limited on the rotating area. The feeding mechanism is a vibratory feeder.

[0008] The workpiece bending mechanism includes a bending section and a bending power source that drives the bending section to make linear reciprocating motion in the direction of the rotation area. The bending power source drives the bending section to move in the direction of the rotation area, thereby forming a bending action on the workpiece to be bent, which is located on the workpiece placement area.

[0009] The beneficial effect of the above structure is that by including an operating table, a control center for controlling the movement of the bending device, a feeding mechanism, a feeding track connected to the outlet of the feeding mechanism, a workpiece clamping area distributed on the outlet end of the feeding track, and a workpiece bending mechanism distributed on one side of the workpiece clamping area, and by including a rotating area on the operating table and a positioning area distributed on one side of the rotating area in the working phase of the oil pipe joint bending device, the control center can drive the oil pipe joint bending device to move. That is, after the oil pipe joint to be bent enters the workpiece placement area of ​​the rotating area through the feeding mechanism and the feeding track, the auxiliary limit of the positioning area is formed, and the workpiece bending mechanism moves with the rotation of the rotating area. When the workpiece reaches one side of the bending mechanism, the rotating area stops rotating, and the bending part is driven by the bending power source on the workpiece bending mechanism to move towards the rotating area and perform the bending action on the oil pipe joint to be bent. After the oil pipe joint has been bent, the rotating area moves again, so that the oil pipe joint to be bent on the subsequent workpiece placement area enters the position of the corresponding workpiece bending mechanism. This also realizes the uninterrupted operation of the bending device on the oil pipe joint to be bent. After the oil pipe joint that has been bent is released from the positioning area, it is automatically pulled out of the workpiece placement area on the rotating area after the rotating area rotates. At the same time, the product qualification rate and production efficiency of the oil pipe joint after bending are greatly improved compared with the existing ones, and the batch operation requirements can be met.

[0010] The present invention is further configured such that the bending device also includes a rotation area positioning mechanism, the rotation area positioning mechanism includes a top contact part and a top contact driving source that drives the top contact part to reciprocate linearly toward the edge of the rotation area. Through the top contact driving source, the top contact part is driven to make contact or move away from the edge of the rotation area, forming a floating limit or limit contact of the rotation area.

[0011] The bending device also includes a rotation zone positioning mechanism. This is because even after the rotation zone has been fixed in place, it may still deflect slightly when the workpiece bending mechanism is applied to the oil pipe joint to be bent. Therefore, the rotation zone positioning mechanism can reliably limit the rotation zone, thereby ensuring the forming accuracy of the oil pipe joint after bending. This further ensures the pass rate of the oil pipe joint and the reliability of the bending operation of the bending device.

[0012] The present invention is further configured such that the bending device also includes a hooking mechanism, the hooking mechanism including a hooking part and a hooking drive source for driving the hooking part to reciprocate linear motion in the rotation area. Through the hooking drive source, the hooking part performs a hooking action in the direction of the rotation area, forming a molded part that does not automatically drop material, and performing auxiliary material feeding.

[0013] With the aforementioned hooking mechanism, each time a pipe joint is bent and formed, the hooking mechanism will perform a hooking action towards the rotation area. This allows for assisted unloading of the bent pipe joint even if it is not automatically pulled out of the workpiece placement area with the rotation of the rotation area. This further ensures the reliability of the bending mechanism design and minimizes the risk of the bent pipe joint entering the workpiece placement area due to its inability to be pulled out of the workpiece placement area, thus affecting subsequent bending operations.

[0014] The present invention is further configured such that the operating table has a vertical structure, the operating table includes an operating side, the workpiece clamping area, the workpiece bending mechanism, the rotating area positioning mechanism, and the hooking mechanism are all distributed on the operating side, the feeding track leads to the operating side at its discharge end, the positioning area is distributed in the upper area adjacent to the rotating area, and constitutes the limit of the workpiece to be bent in the upper area of ​​the rotating area, the formed part that has been bent by the workpiece bending mechanism, when it rotates to the lower area of ​​the rotating area with the rotation of the rotating area, constitutes the bent formed part, and performs an automatic unloading action by gravity.

[0015] The above methods ensure that the oil pipe joint to be bent on the rotating area can be conveniently limited by the positioning area, and after disengaging from the positioning area, the already bent oil pipe joint can be easily unloaded.

[0016] This utility model is further configured such that the rotating area is a rotating disk located on a vertical operating table, the rotating disk rotates counterclockwise, the discharge end of the feeding track is located at the top of the rotating disk, the hooking mechanism is located at the bottom of the rotating disk, and multiple bending mechanism mounting positions are provided on the left half of the vertical operating table relative to the rotating disk. The workpiece bending mechanism is installed at the multiple bending mechanism mounting positions according to the bending angle of the workpiece to be bent, thus forming a bending device that can adapt to bending actions of workpieces with multiple angle specifications. The rotating area positioning mechanism is located on the right half of the rotating disk; the multiple bending mechanism mounting positions are all concentrically distributed with the rotating disk.

[0017] The above-mentioned device allows for convenient entry of the tubing connector to be bent into the bending device for bending operations, and provides reliable auxiliary unloading of the already bent tubing connector. It also enables the bending device to adapt to tubing connectors of different specifications for the required bending action, thereby greatly expanding the applicability of the tubing connector and making it not limited to bending operations at a certain angle. This allows the bending device to achieve bending of the tubing connector at any angle, whether positive or negative.

[0018] The present invention is further configured such that the hook material driving source, the top contact driving source, and the bending power source are all electric cylinders. Attached Figure Description

[0025] like Figure 1-6As shown, a specific embodiment of this utility model is an oil pipe joint bending device, including an operating table 3, a control center 1, a feeding mechanism 1, a feeding track 2 connected to the outlet of the feeding mechanism 1, a workpiece clamping area distributed on the outlet end of the feeding track 2, and a workpiece bending mechanism 7 distributed on one side of the workpiece clamping area. The workpiece clamping area includes a rotating area 5 that is limited to the operating table 3 and makes a rotary motion, and a positioning area 8 distributed on one side of the rotating area 5. The rotating area 5 has a plurality of workpiece placement areas. The positioning area 8 is adjacent to the side of the rotating area 5. Through the positioning area 8, one or more workpieces to be bent in the plurality of workpiece placement areas on the workpiece clamping area are limited on the rotating area 5. The feeding mechanism 1 is a vibratory feeder.

[0026] The workpiece bending mechanism 7 includes a bending part 72 and a bending power source 71 that drives the bending part 72 to make linear reciprocating motion in the direction of the rotation area 5. The bending power source 71 drives the bending part 72 to move in the direction of the rotation area 5, thereby forming a workpiece to be bent that is located on the workpiece placement area and performs a bending action. The bending power source 71 is an electric cylinder.

[0027] The above-described tubing joint bending device for bending tubing joint a comprises an operating table 3, a control center 1 for controlling the movement of the bending device, a feeding mechanism 1, a feeding track 2 connected to the outlet of the feeding mechanism 1, a workpiece clamping area distributed on the outlet end of the feeding track 2, and a workpiece bending mechanism 7 distributed on one side of the workpiece clamping area. The workpiece clamping area includes a rotating area 5 limited on the operating table 3 and a positioning area 8 distributed on one side of the rotating area 5. Thus, during the working phase of the tubing joint bending device, the control center 1 can drive the tubing joint bending device to move. Specifically, the tubing joint a to be bent enters the workpiece placement area of ​​the rotating area 5 through the feeding mechanism 1 and the feeding track 2. After being auxiliaryly limited by the positioning area 8, the workpiece is bent as the rotating area 5 rotates. When the workpiece bending mechanism 7 is in one side, the rotating area 5 stops rotating, and the bending part 72 is driven to move toward the rotating area 5 by the bending power source 71 on the workpiece bending mechanism 7, and performs the bending action on the oil pipe joint a to be bent. After the oil pipe joint a has been bent, the rotating area 5 moves again, so that the oil pipe joint a to be bent on the subsequent workpiece placement area enters the position of the corresponding workpiece bending mechanism 7. This also realizes the uninterrupted operation of the bending device on the oil pipe joint a to be bent. After the oil pipe joint a that has been bent is released from the positioning area 8, it is automatically pulled out of the workpiece placement area on the rotating area 5 after the rotating area 5 rotates. At the same time, the product qualification rate and production efficiency of the oil pipe joint a after bending are greatly improved compared with the existing ones, and the batch operation requirements can be met.

Through the top contact drive source 42, the top contact part 41 is driven to make contact or move away from the edge of the rotation area 5, forming a floating limit or limit contact of the rotation area 5. The top contact drive source 42 is an electric cylinder.

[0029] like Figure 1 , 4 As shown in Figure 6, the bending device also includes a hooking mechanism 6, which includes a hooking part 61 and a hooking drive source 62 that drives the hooking part 61 to reciprocate linearly in the rotation area 5. Through the hooking drive source 62, the hooking part 61 performs a hooking action in the direction of the rotation area 5, forming a molded part that is not automatically unloaded, and performing auxiliary unloading. The hooking drive source 62 is an electric cylinder.

[0030] like Figure 1-6 As shown, the operating table 3 has a vertical structure. The vertical operating table 3 includes an operating side b, a workpiece clamping area, a workpiece bending mechanism 7, a rotating area positioning mechanism 4, and a hooking mechanism 6, all of which are distributed on the operating side b. The feeding track 2 leads to the operating side b at its discharge end. The positioning area 8 is distributed in the upper area adjacent to the rotating area 5, and the workpiece to be bent in the upper area is limited in the rotating area 5. The formed part that has been bent by the workpiece bending mechanism 7 rotates to the lower area of ​​the rotating area 5 with the rotation of the rotating area 5, forming a bent formed part, and then automatically unloads the part by gravity.

[0031] like Figure 1-6 As shown, the rotating area 5 is a rotating disk located on the vertical operating table 3. The rotating disk rotates counterclockwise. The feeding track 2 has its discharge end located at the top of the rotating disk. The hooking mechanism 6 is located at the bottom of the rotating disk. Multiple bending mechanism mounting positions 31 are provided on the left half of the vertical operating table 3 relative to the rotating disk. The workpiece bending mechanism 7 is installed on the multiple bending mechanism mounting positions 31 according to the bending angle of the workpiece to be bent, and forms a bending device that can adapt to the bending action of workpieces with multiple angle specifications. The rotating area positioning mechanism 4 is located on the right half of the rotating disk. The multiple bending mechanism mounting positions 31 are all concentrically distributed with the rotating disk.
