Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicle parts processing, in particular to a pipe bending die for a direction handle pipe fitting. Background Art

[0002] An electric vehicle is a vehicle driven by electricity. The electric vehicle uses a battery as an energy source and converts electrical energy into mechanical energy through components such as a controller and a motor to move, and controls the vehicle speed by changing the magnitude of the current. Electric vehicles are very common, and the direction handle of an electric vehicle is an important component. The two ends of the direction handle are bent to facilitate the user to hold the handle, and the included angle between the two ends and the middle part is an obtuse angle.

[0003] During processing, if manual bending is relied on, a large amount of manpower is required. When using machine processing, the press bending process is mostly used. The press bending operation is relatively simple, but the bending angle is large during press bending, which is more suitable for the processing of pipe fittings with a large bending angle. However, the bending angle of the direction handle is small. In addition, accurate angle control cannot be achieved by press bending. For the direction handle, the accuracy of the bending angle directly affects the quality of the product.

[0004] In view of the above problems, the present utility model document proposes a pipe bending die for a direction handle pipe fitting. Content of the Utility Model

[0005] The utility model provides a pipe bending die for a direction handle pipe fitting, which ensures the processing accuracy of the product, reduces the labor intensity of workers, and improves the processing efficiency.

[0006] The utility model provides the following technical solutions:

[0007] A pipe bending die for a direction handle pipe fitting includes a pipe bending die, a pressing die, and a guiding die. The pipe bending die is a circular cylindrical structure, and its side wall is provided with an annular groove. A notch is provided on the side wall of the pipe bending die, and a pipe bending support die is clamped at the notch. A support groove communicating with the annular groove is provided on one side surface of the pipe bending support die. The pressing die abuts against the side surface of the pipe bending support die where the support groove is provided, and a pressing groove matching with the support groove is provided on the side surface of the pressing die adjacent to the pipe bending support die. The guiding die abuts against the pipe bending die, and a positioning groove matching with the annular groove is provided on one side surface of the guiding die. The guiding die is located on the side of the pipe bending die for loading materials. The cross sections of the annular groove, the support groove, the pressing groove, and the positioning groove are all semi-circular, and the positioning groove and the annular groove cooperate to clamp the feeding pipe fitting, and the pressing groove and the support groove cooperate to clamp the feeding pipe fitting.

[0008] Furthermore, a circular first limiting groove is provided on the side wall of the pipe bending die, and the annular groove is arranged along the bottom surface of the first limiting groove.

[0009] Further, a second limiting groove spliced with the first limiting groove is provided on the elbow support die, and the support groove is arranged on the bottom surface of the second limiting groove.

[0010] Further, a mounting seat is connected to the other side of the guiding die symmetric to the side where the positioning groove is provided. A clamping block is provided on the guiding die, and a matching clamping groove is formed on the mounting seat. The guiding die is connected to the mounting seat through the cooperation of the clamping block and the clamping groove. A threaded mounting hole is provided at the position corresponding to the clamping groove on the side surface of the mounting seat, and a threaded connection hole is formed at the corresponding position of the clamping block. The clamping block and the clamping groove are fixed by a bolt passing through the threaded mounting hole and the threaded connection hole.

[0011] Further, a dovetail groove is formed on the other side of the mounting seat symmetric to the side connected to the guiding die, and a dovetail groove is formed on the other side of the pressing die symmetric to the side where the pressing groove is provided.

[0012] Further, the widths of the first limiting groove and the second limiting groove, the thickness of the pressing die, and the thickness of the guiding die are the same.

[0013] Further, a threaded hole is provided at the clamping notch of the elbow die, a countersunk head hole communicating with the threaded hole is formed on the elbow support die, and the elbow support die and the elbow die are connected by a countersunk head bolt.

[0014] In the present utility model, the feeding pipe fitting is clamped by the cooperation of the pressing groove and the support groove, and the feeding pipe fitting is clamped by the cooperation of the positioning groove and the annular groove. Then, an external power device drives the elbow die to rotate. At the same time, the pressing die rotates together with the elbow die, while the guiding die moves towards the pressing die direction to ensure that the guiding die and the elbow die always cooperate to clamp the feeding pipe fitting. As the elbow die rotates, the feeding pipe fitting is bent along the annular groove on the side wall of the elbow die. The feeding pipe fitting always fits with the elbow die during the bending process, thereby ensuring that the feeding pipe fitting will not be deformed as a whole. The guiding die ensures that the other side of the feeding pipe fitting will not warp during bending and affect the bending operation. At the same time, during the whole process, the feeding pipe fitting is clamped by the cooperation of the pressing groove and the support groove and the cooperation of the positioning groove and the annular groove, avoiding the rotation of the feeding pipe fitting and affecting the bending direction of the feeding pipe fitting, improving the processing precision of the product, and ensuring the product quality.

[0033] Embodiment:

[0034] Refer to Figures 1 to 11As shown in the figure, a pipe bending die for a direction handle pipe fitting includes a pipe bending die 1, a pressing die 2 and a guiding die 3. The pipe bending die 1 is of a circular cylindrical structure, and its side wall is provided with an annular groove 101. A clamping notch is provided on the side wall of the pipe bending die 1, and a pipe bending support die 5 is clamped at the clamping notch. A support groove 501 communicating with the annular groove 101 is provided on one side surface of the pipe bending support die 5; The pressing die 2 abuts against the side surface of the pipe bending support die 5 where the support groove 501 is provided, and a pressing groove 201 matching with the support groove 501 is provided on the side surface of the pressing die 2 adjacent to the pipe bending support die 5; The guiding die 3 abuts against the pipe bending die 1, and a positioning groove 301 matching with the annular groove 101 is provided on one side surface of the guiding die 3. The guiding die 3 is located on the side where the pipe bending die 1 feeds materials. The cross-sections of the annular groove 101, the support groove 501, the pressing groove 201 and the positioning groove 301 are all semi-circular, and the positioning groove 301 and the annular groove 101 cooperate to clamp the feeding pipe fitting, and the pressing groove 201 and the support groove 501 cooperate to clamp the feeding pipe fitting.

[0035] The positioning groove 301 and the annular groove 101 cooperate to form a clamping hole with the same cross-section as the feeding pipe fitting, and clamp the feeding pipe fitting. The pressing groove 201 and the support groove 501 cooperate to form a clamping hole with the same cross-section as the feeding pipe fitting, and clamp the feeding pipe fitting. The pipe bending die 1 is installed on an external rotating device to drive the pipe bending die 1 to rotate. At the same time, the pressing die 2 rotates together with the pipe bending die 1 to ensure that the pressing die 2 can clamp the feeding pipe fitting with the pipe bending support die 5 when the pipe bending die 1 rotates. Since the feeding pipe fitting will move a certain distance along the side wall of the pipe bending die 1 while being bent, the guiding die 3 will move a certain distance towards the pressing die 2 to ensure that the guiding die 3 and the pipe bending die 1 can closely cooperate to clamp the feeding pipe fitting when the pipe bending die 1 rotates. The pressing die 2 and the pipe bending support die 5 rotate together to bend the feeding pipe fitting. Moreover, the feeding pipe fitting is closely attached to the annular groove 101 during the whole bending process, ensuring that the feeding pipe fitting will not be deformed as a whole while being bent. At the same time, the pressing groove 201 and the support groove 501 cooperate and the positioning groove 301 and the annular groove 101 cooperate to clamp the feeding pipe fitting during the whole process, avoiding the rotation of the feeding pipe fitting and affecting the bending direction of the feeding pipe fitting, improving the processing accuracy of the product and ensuring the product quality.

[0036] A ring-shaped first limiting groove 102 is provided on the side wall of the pipe bending die 1, and the annular groove 101 is arranged along the bottom surface of the first limiting groove 102.

[0037] The first limiting groove 102 is provided on the side wall of the pipe bending die 1. When the guiding die 3 abuts against the pipe bending die 1, it is clamped in the first limiting groove 102 to ensure the precise cooperation between the positioning groove 301 and the annular groove 101, and then clamp the feeding pipe fitting. At the same time, when the pipe bending die 1 rotates, it avoids the feeding pipe fitting being stressed and causing the guiding die 3 to deflect relative to the pipe bending die 1, resulting in the deformation of the feeding pipe fitting.

[0038] The elbow support mold 5 is provided with a second limiting groove 502 that is spliced with the first limiting groove 102, and the support groove 501 is arranged on the bottom surface of the second limiting groove 502.

[0039] A second limiting groove 502 is arranged on the elbow support mold 5. The pressing mold 2 is clamped by the second limiting groove 502. When the pressing mold 2 abuts against the elbow support mold 5, it is clamped in the second limiting groove 502. On the one hand, it ensures that the pressing groove 201 and the support groove 501 are precisely matched to clamp the feeding pipe fitting. At the same time, when the pressing mold 2 rotates with the elbow mold 1 to bend the feeding pipe fitting, the pressing mold 2 is prevented from deflecting under force, resulting in the deformation of the feeding pipe fitting.

[0040] On the side of the guiding mold 3 opposite to the side where the positioning groove 301 is provided, a mounting seat 4 is connected. The guiding mold 3 is provided with a clamping block 302, and a matching clamping groove 401 is opened on the mounting seat 4. The guiding mold 3 is connected to the mounting seat 4 through the cooperation of the clamping block 302 and the clamping groove 401. Threaded mounting holes are provided at the positions corresponding to the clamping groove 401 on the side surface of the mounting seat 4, and threaded connection holes are opened at the corresponding positions of the clamping block 302. By passing bolts through the threaded mounting holes and the threaded connection holes, the clamping block 302 and the clamping groove 401 are fixed.

[0041] The guiding mold 3 is convenient to be connected to external power equipment through the mounting seat 4. At the same time, it is fixed by bolts, which is convenient for disassembly and assembly, enabling the user to select a suitable guiding mold 3 according to the diameter of the pipe fitting to be processed and install it on the external equipment during actual production.

[0042] On the side of the mounting seat 4 opposite to the side where the guiding mold 3 is connected, a dovetail groove 6 is opened. On the side of the pressing mold 2 opposite to the side where the pressing groove 201 is opened, a dovetail groove 6 is also opened.

[0043] The connection through the dovetail groove 6 is convenient for connection to external power equipment on the one hand, and on the other hand, it is also convenient for the power equipment to drive the mounting seat 4 or the pressing mold 2 to move in the direction perpendicular to the dovetail groove 6, improving the efficiency of mold installation and reducing the working difficulty of workers.

[0044] The width of the first limit, the width of the second limiting groove 502, the thickness of the pressing mold 2, and the thickness of the guiding mold 3 are the same.

[0045] This makes the pressing mold 2 stably clamped in the second limiting groove 502 and the guiding mold 3 stably clamped in the first limiting groove 102, preventing sliding and affecting the clamping stability of the feeding pipe fitting, further improving the product processing accuracy and ensuring the product quality.

[0046] A dovetail groove 6 is opened at the notch of the elbow mold 1, and the elbow support mold 5 is provided with a limiting block that matches the dovetail groove 6, which is convenient for quickly installing the elbow support mold 5 at the notch and enabling the elbow mold 1 to drive the elbow support mold 5 to move together.

[0047] The clamping notch of the elbow bending die 1 is provided with a threaded hole, and the elbow bending support die 5 is provided with a countersunk hole communicating with the threaded hole. The elbow bending support die 5 and the elbow bending die 1 are connected by a countersunk bolt.

[0048] Connecting the elbow bending support die 5 and the elbow bending die 1 by a countersunk bolt further improves the connection stability between the elbow bending support die 5 and the elbow bending die 1, and at the same time does not affect the clamping stability of the feeding pipe fitting.

[0049] During use, the feeding pipe fitting is input from the direction of the guiding die 3. The feeding pipe fitting is clamped by the pressing die 2 in cooperation with the elbow bending support die 5. At the same time, the guiding die 3 in cooperation with the elbow bending die 1 also clamps the feeding pipe fitting. Then, the elbow bending die 1 is driven to rotate by an external power device. At the same time, the pressing die 2 rotates by the same angle as the elbow bending die 1, ensuring that the pressing die 2 and the elbow bending support die 5 always closely cooperate to clamp one side of the bending position of the feeding pipe fitting. Therefore, when the pressing die 2 rotates, it will bend the clamped feeding pipe fitting. At the same time, the guiding die 3 and the elbow bending die 1 closely cooperate to clamp the other side of the bending position of the feeding pipe fitting, thereby bending the feeding pipe fitting along the elbow bending die 1; and during the bending process, the feeding pipe fitting is always kept in a clamped state to prevent the feeding pipe fitting from rolling and affecting the bending direction.

[0050] In actual use, the elbow bending die 1 and the pressing die 2 are installed on the same rotating platform. The pressing die 2 is also connected to a cylinder through a dovetail groove 6. The guiding die 3 is installed on a fixed platform. At the same time, the guiding die 3 is connected to a cylinder along the conveying direction of the feeding pipe fitting and a cylinder in the vertical direction, so that it can not only push the guiding die 3 to be clamped in the first limiting groove 102 of the elbow bending die 1, but also move a certain distance in the direction of the pressing die 2 during bending, ensuring that when the elbow bending die 1 rotates, the guiding die 3 and the elbow bending die 1 always closely cooperate to clamp the feeding pipe fitting.

[0051] The end of the elbow bending die 1 is provided with a positioning hole, which is convenient for the elbow bending die 1 to be driven to rotate after being installed on the rotating platform.

[0052] This die has a simple structure, improves the processing accuracy of the product, ensures the quality of the product, and is suitable for popularization.

[0053] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention, and all should be covered by the protection scope of the present invention; without conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
