Description

Technical Field

[0001] This utility model relates to a processing equipment for quick couplings of fuel lines, and particularly to a cold bonding device for quick couplings of fuel lines. Background Technology

[0002] Fuel line quick couplings are key components in automotive fuel systems, primarily used to connect fuel lines, ensuring smooth fuel delivery and system sealing. To prevent fuel lines from easily loosening or breaking during use, the production process of fuel line quick couplings typically involves cold heading to create an end cap that fits tightly to the connection point of the fuel line. This enhances the mechanical strength of the coupling, reduces the risk of failure, and ultimately improves the reliability and safety of the entire fuel system.

[0003] In existing cold heading equipment for quick fuel line connectors, metal blanks are usually placed into a pre-designed mold, and then pressure is applied to the metal blank in the mold cavity by the hydraulic system of the cold heading machine to cause plastic deformation and produce the head of the required shape. This method has the problem that the dimensional accuracy of the head of the product is prone to deviation, and it cannot adapt to the processing of head of different sizes and specifications, resulting in inconsistent production quality and low efficiency. Utility Model Content

[0004] The technical problem this utility model aims to solve is to provide a cold forging device for quick fuel line connectors. By using an adjusting positioning bolt to determine the position of the product to be processed on the platform, a second drive device pushes a rotating rod to move the positioning bolt away from the top surface of the platform. Then, a first drive device pushes a pressure block connected to a pressing groove and a limiting groove to clamp the product to be processed onto the platform. A third drive device drives a sliding block to slide, and a forming sleeve connected to the sliding block performs cold forging operations on the portion of the product within the pressing groove. This device allows for quick and precise adjustment and positioning of the product, adapting to different specifications of forging heads and effectively improving the efficiency and quality of cold forging production of quick fuel line connectors.

[0005] This utility model is achieved through the following technical solution:

[0006] A cold bonding device for quick-connect fuel lines includes a base and a power unit, which includes a motor and a hydraulic pump. The power unit is connected to the inside of the base. A U-shaped support is connected to the top surface of the base. A platform is connected to the bottom inner surface of the support. A drive device one with its output end perpendicular to the top surface of the platform is connected to the support directly above the platform. A pressure block is vertically connected to the end of the output end of the drive device one. A drive device two is rotatably connected to the side of the support one, which is parallel to both ends of the platform. A limiter is connected to the end of the output end of the drive device two. A pressing component and a drive device three are sequentially connected to the top surface of the base next to the limiter. The pressing component includes a slider and a forming sleeve. The end of the output end of the drive device three is connected to the slider. The forming sleeve is vertically connected to the surface of the slider opposite to the limiter.

[0007] Furthermore, the driving device is a hydraulic cylinder, and the platform includes a support block, two guide rods, a limiting groove and a pressing groove. The support block is connected to the inner bottom surface of the support, the guide rods are vertically connected to the top surface of the support block near the inner side of the support, and the limiting groove and pressing groove are connected to the top surface of the support block next to the guide rod.

[0008] Furthermore, the limiting groove and the pressing groove are connected and coincide with the horizontal central axis. The two ends where the pressing groove and the limiting groove are located are respectively vertically connected to the two sides opposite to the opening side of the support block and the support.

[0009] Furthermore, the bottom surface of the pressure block is connected to a guide hole adapted to the shape of the guide rod at a position directly opposite the vertical guide rod. The bottom surface of the pressure block, which is directly opposite the limiting groove and the pressing groove, is connected to a groove of corresponding shape. The end of the pressure block opposite the pressing groove is shortened by half the length of the pressing groove compared to the size of the support block.

[0010] Furthermore, when the pressure block presses down on the stage, the cross-sectional shape of the limiting groove is the same as the cross-sectional shape of the product, and the cross-sectional diameter of the pressing groove is five millimeters larger than the cross-sectional diameter of the output end of the forming sleeve.

[0011] Furthermore, the second driving device is a hydraulic rod, and the limiting component includes a connecting plate, a positioning bolt, and a rotating rod. The connecting plate is parallel to the side of the support opposite to the end of the pressing groove, and one end of the positioning bolt and the rotating rod are respectively vertically connected to the two ends of the connecting plate opposite to the support.

[0012] Furthermore, the rotating rod passes through and is rotatably connected to the support. The other end of the rotating rod is vertically connected to a connecting rod, which is rotatably connected to the output end of the second drive device. The central axis distance between the rotating rod and the positioning bolt is equal to the central axis distance between the rotating rod and the limiting groove.

[0013] Furthermore, the third drive device is a hydraulic cylinder. The output end of the third drive device is perpendicular to the side of the support parallel to both ends of the platform. Two guide rails are symmetrically connected on the top surface of the base on both sides of the third drive device with the output end of the third drive device as the axis. The bottom of the slider is connected to a sliding groove, and the slider is slidably connected to the guide rail through the sliding groove.

[0014] Furthermore, a hole adapted to the shape of the product end is vertically connected at the center of the top surface of the end of the molding sleeve, and the central axis of the molding sleeve coincides with the central axis of the limiting groove and the pressing groove.

[0015] Compared with the prior art, this utility model has the following obvious advantages:

[0016] I. In this utility model, the output end of the drive device is perpendicular to the top surface of the platform, and the pressure block is vertically connected to the end of the output end of the drive device. A limiting groove adapted to the shape of the product is connected to the top surface of the platform and the bottom surface of the vertically opposite pressure block. After the operator places the product in the limiting groove on the top surface of the platform, he controls the drive device to drive the output end to push it out. The output end pushes the pressure block down to press it on the top surface of the platform. The limiting groove completely limits the position of the product on the cold heading device, ensuring the accuracy of product processing and improving production efficiency and quality.

[0017] II. In this utility model, a limiting groove and a pressing groove are connected on the top surface of the platform and the bottom surface of the vertically opposite pressing block. The central axes of the limiting groove and the pressing groove coincide and are connected. The two ends of the groove formed by the connection of the two grooves are vertically connected to the two side surfaces of the platform. The pressing groove coincides with the central axis of the forming sleeve, and the cross-sectional diameter of the pressing groove is 5 mm larger than the cross-sectional diameter of the output end of the forming sleeve. A hole that matches the shape of the product end is vertically connected at the center of the top surface of the end of the forming sleeve. When the product is cold-forged, the output end of the forming sleeve is pressed into the pressing groove, and the product after limiting is processed. The processing process is more convenient and faster.

[0018] Third, this utility model features a rotatable limiting component connected to the support side opposite the pressing component. The output end of the second drive device is rotatably connected to the connecting rod on the rotating rod of the limiting component. The central axis distance between the rotating rod and the positioning bolt is equal to the central axis distance between the rotating rod and the limiting groove. The rotating rod is pushed to rotate by the second drive device to adjust the position of the positioning bolt. The initial position of the positioning bolt is when the central axis coincides with the central axis of the limiting groove. When the operator places the product to be processed in the limiting groove, one end of the product abuts against the positioning bolt. The length of the product extending into the pressing groove can be adjusted by changing the position of the positioning bolt, thereby changing the size of the processed head. It can quickly adapt and adjust to different specifications. Attached Figure Description

On the top surface of the support block 401, the limiting groove 403 and the pressing groove 404 are interconnected and coincident in horizontal direction. The two ends of the pressing groove 404 and the limiting groove 403 are vertically connected to the two sides of the support block 401 and the side of the support 3 opposite to the opening.

The bottom surface of the pressing block 5, which is vertically opposite the limiting groove 403 and the pressing groove 404, has grooves of corresponding shape. The end of the pressing block 5 opposite to the pressing groove 404 is half the length of the pressing groove 404 compared to the support block 401. When the pressing block 5 presses the platform 4, the cross-sectional shape of the limiting groove 403 is the same as the cross-sectional shape of the product 13. The cross-sectional diameter of the pressing groove 404 is five millimeters larger than the cross-sectional diameter of the output end of the molding sleeve 12.

[0027] The second drive device 7 is rotatably connected to the side of the support 3 opposite to the end of the limiting groove 403. The limiting component 8 includes a connecting plate 801, a positioning bolt 802, and a rotating rod 803. The connecting plate 801 is parallel to the side of the support 3 opposite to the end of the pressing groove 404. One end of the positioning bolt 802 and the rotating rod 803 are respectively vertically connected to the two ends of the connecting plate 801 opposite to the support 3. The rotating rod 803 passes through and is rotatably connected to the support 3. The other end of the rotating rod 803 is vertically connected to a connecting rod. The connecting rod is rotatably connected to the output end of the second drive device 7. The central axis distance between the rotating rod 803 and the positioning bolt 802 is equal to the central axis distance between the rotating rod 803 and the limiting groove 403.

[0028] The pressing component and the driving device 39 are sequentially connected to the top surface of the base 1 next to the limiting component 8. The pressing component includes a slider 11 and a forming sleeve 12. The output end of the driving device 39 is perpendicular to the side of the support 3 parallel to both ends of the platform 4. The end of the output end of the driving device 39 is connected to the slider 11. Two guide rails 10 are symmetrically connected on the top surface of the base 1 on both sides of the driving device 39 with the output end of the driving device 39 as the axis. The bottom of the slider 11 is connected to a sliding groove. The slider 11 is slidably connected to the guide rail 10 through the sliding groove. The forming sleeve 12 is vertically connected to the surface of the slider 11 opposite to the limiting component 8. A hole that matches the shape of the end of the product 13 is vertically connected at the center of the top surface of the end of the forming sleeve 12. The central axis of the forming sleeve 12 coincides with the central axis of the limiting groove 403 and the pressing groove 404.

[0029] The working principle of this utility model is as follows:

[0030] During operation, the detection device is used in conjunction with a PLC controller.

[0031] When using this utility model, the operator turns on the PLC controller. In the initial state, the output ends of drive device 1 6 and drive device 3 9 are both in a retracted state. The pressure block 5 is away from the top surface of the platform 4. The positioning bolt 802 is located at the position where the central axis coincides with the central axis of the limiting groove. The operator rotates the positioning bolt 802 according to the size and specifications of the pier to be processed, adjusts the horizontal position of the positioning bolt 802 in the pressing groove 404, and after determining the position of the positioning bolt 802, the operator places the product 13 to be processed in the limiting groove 403 on the top surface of the platform 4 and manually adjusts the position of the product 13 so that one end of the product 13 abuts against the positioning bolt 802.

[0032] After the operator places product 13, the PLC controller controls drive device 6 to push out its output end. The output end of drive device 6 pushes the pressure block 5 downward. The hole connected to the bottom surface of the pressure block 5 fits onto the guide rod 402. When the bottom surface of the pressure block 5 is in contact with the top surface of the platform 4, drive device 6 stops operating. The limiting groove 403 and the corresponding groove connected to the bottom surface of the pressure block 5 together clamp product 13, limiting the position of product 13. After product 13 is limited, the operator controls drive device 7 and drive device 9 to run sequentially through the PLC controller. Drive device 7... The output end retracts, pulling the connecting rod at the end to rotate. The connecting rod drives the rotating rod 803 to rotate. The connecting plate 801 connected to the other end of the rotating rod 803 rotates upward about the rotating rod 803 as the axis. The rotating rod 803 drives the positioning bolt 802 away from the pressing groove 404. The output end of the drive device 3 9 is pushed out, pushing the slider 11 to slide along the guide rail 10. The forming sleeve 12 enters the pressing groove 404 with the movement of the slider 11 and is sleeved on the end of the product 13. When the forming sleeve 12 abuts against the end of the product 13, cold heading begins. When the drive device 3 9 stops running, cold heading ends.

[0033] After the cold heading process is completed, the PLC controller controls the output end of drive device 9 to retract, pulling back the slider 11 and the forming sleeve 12. After the forming sleeve 12 moves away from the pressing groove 404, the PLC controller controls drive device 7 to push out the output end, pushing the connecting rod connected at the end to rotate. The connecting rod drives the rotating rod 803 to rotate. The connecting plate 801 connected to the other end of the rotating rod 803 rotates downward around the rotating rod 803 as the axis. The rotating rod 803 drives the positioning bolt 802 to fall back into the pressing groove 404. At the same time, the PLC controller controls the output end of drive device 6 to retract, and the output end of drive device 6 pulls the pressing block 5 up to return to its original position. The operator takes the product 13 out of the limiting groove 403, obtaining the product 13 with the required size and specifications of the head.

They should not be construed as limiting the scope of protection of this utility model.
