Description

Technical Field

[0001] The utility model belongs to the technical field of pipeline production, and particularly relates to an efficient arc pressing device for producing pipeline end heads. Background Technique

[0002] In daily production and life, pipelines play a crucial role in transporting media. When actually using pipelines, pipeline end heads generally need to be installed at both ends, branch ports or conversion ports of the pipelines to seal the pipelines and prevent problems such as backflow, spillage or improper discharge of substances in the pipelines. Pipeline end heads are mostly produced and completed by relying on punching dies and stamping equipment.

[0003] Based on the above, the inventor found the following problems: The production material of the pipeline end head is a circular steel plate. Therefore, in order to ensure that the manufactured pipeline end head meets the required standards, the center position of the circular steel plate needs to be aligned with the center of the lower die. However, manual adjustment by workers is time-consuming and has low efficiency and accuracy. Moreover, the pipeline end head formed after stamping the circular steel plate is easy to adhere to the bottom of the upper die, and it needs to be manually peeled off, or lubricating grease is manually applied to the surface of the circular steel plate to facilitate demoulding. Such an operation method reduces work efficiency and increases the labor intensity of workers.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and an efficient arc pressing device for producing pipeline end heads is provided, in order to achieve the purpose of having more practical value. Content of the Utility Model

[0005] In order to solve the above technical problems, the utility model provides an efficient arc pressing device for producing pipeline end heads, which is achieved by the following specific technical means:

[0006] An efficient arc pressing device for producing pipeline end heads includes a base, legs installed below the base, and a fixed seat fixedly arranged above the base. A through hole is provided on the top surface of the base, and a lower die is installed on the top surface of the base. A plurality of arc-shaped grooves are arranged in a circumferential array on the top surface of the lower die. One end of the arc-shaped groove is close to the inner side of the lower die and the other end is close to the outer side of the lower die. A cylindrical slider is slidably installed in each of the plurality of arc-shaped lower dies. A ring-shaped base is rotatably installed at the top end of the lower die. A plurality of rectangular grooves with the same number as the arc-shaped grooves are radially arranged through the surface of the ring-shaped base. A rectangular slider is slidably installed in each of the plurality of rectangular grooves. The rectangular slider is connected to the cylindrical slider at the bottom. A limiting block is further installed at the top of the rectangular slider. A demoulding component is installed on the bottom surface of the base.

[0007] Furthermore, a hydraulic jack is installed below the fixed seat, and an upper die matching the lower die is installed at the end of the output end of the hydraulic jack. The upper die and the lower die are concentrically arranged.

[0008] Furthermore, one side of the limiting block facing the inner side of the lower mold is arc-shaped.

[0009] Furthermore, the inner wall of the annular base is inclined, and the diameter of the inner wall at the bottom of the annular base is the same as the inner diameter of the lower mold.

[0010] Furthermore, a handle is fixedly installed on the outer wall of the annular base.

[0011] Furthermore, the demolding assembly includes a plurality of hollow bases fixedly installed on the lower surface below the top of the base. One side of each of the plurality of hollow bases is provided with an opening. One end of each hollow base with the opening faces the center of the lower mold. A connecting block is slidably connected inside the hollow base. A spring is installed inside the hollow base. Two ends of the spring respectively abut against the connecting block and the inner wall of the hollow base. A trapezoidal block is installed on one side of the connecting block away from the spring. One side of the trapezoidal block away from the spring passes through the center of the through hole of the hollow base. The end of the trapezoidal block on the side where it passes through is slidably connected to the top side wall of the upper mold, and the end of the trapezoidal block where it passes through is inclined.

[0012] Furthermore, a limiting ring is installed on the inner wall of the hollow base at the opening.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By the combined use of the arc-shaped groove, cylindrical slider, annular base, rectangular groove, rectangular slider and limiting block, the utility model can realize that when the annular base is rotated, the rectangular slider installed in the rectangular groove moves accordingly. Since the bottom of the rectangular slider is connected to the cylindrical slider, the cylindrical slider at its bottom is driven to move synchronously along the arc-shaped groove. With the cooperation of the rectangular slider and the cylindrical slider, the connecting block installed at the top of the rectangular slider is translated in a fixed direction, so as to fix the circular steel plate installed on the top of the annular base. Moreover, the angles formed between the multiple arc-shaped grooves and the multiple rectangular grooves and the inner side of the lower mold are the same. Therefore, the moving speeds and distances of the limiting blocks are all synchronous, so as to accurately position the center of the circular steel plate, thereby improving the production efficiency and production quality of the device.

[0015] 2. By the combined use of the hollow base, connecting block, spring, and trapezoidal block, the present utility model can achieve that during the stamping operation, the circular steel plate on the bottom surface of the upper die will push the trapezoidal block and the connecting block under the lower die into the hollow base during the stamping process and compress the spring. After the stamping operation is completed, the spring pushes the trapezoidal block at one end of the connecting block to approach the side surface of the top of the upper die again. As the hydraulic ejector rod drives the upper die to retract, and since the diameter of the pipe head after stamping and forming is larger than the diameter of the upper die, under the reverse force of the trapezoidal block, the pipe head is separated from the surface of the upper die, thus realizing the demoulding of the pipe head without manual intervention, thereby improving the operation efficiency of the device and reducing the labor intensity of the operator.

[0026] Embodiment:

[0027] As shown in the attached Figure 1 to the attached Figure 5 figure:

[0028] An efficient arc pressing device for producing pipe end caps, comprising a base 1, legs installed below the base 1, and a fixed seat 11 fixedly arranged above the base 1. The top surface of the base 1 is provided with a through hole. A lower die 2 is installed on the top surface of the base 1. A plurality of arc-shaped grooves 3 are arranged in a circumferential array on the top surface of the lower die 2. One end of the arc-shaped groove 3 is close to the inner side of the lower die 2 and the other end is close to the outer side of the lower die 2. A cylindrical slider 4 is slidably installed in each of the plurality of arc-shaped lower dies 2. A ring-shaped base 5 is rotatably installed at the top end of the lower die 2. Rectangular slots 6 with the same number as the arc-shaped grooves 3 are arranged radially through the surface of the ring-shaped base 5. A rectangular slider 7 is slidably installed in each of the plurality of rectangular slots 6. The rectangular slider 7 is connected to the cylindrical slider 4 at the bottom. A limit block 8 is further installed at the top of the rectangular slider 7. Through the cooperation of the arc-shaped groove 3, the cylindrical slider 4, the ring-shaped base 5, the rectangular slot 6, the rectangular slider 7, and the limit block 8, when the ring-shaped base 5 is rotated, the rectangular slider 7 installed in the rectangular slot 6 moves accordingly. Since the bottom of the rectangular slider 7 is connected to the cylindrical slider 4, the cylindrical slider 4 at its bottom is driven to move synchronously. The arc-shaped groove 3 slidably connected to the cylindrical slider 4 is designed such that one end is close to the inner side of the lower die 2 and the other end is far from the inner side of the lower die 2. Thus, the moving track of the cylindrical slider 4 is in an arc form, approaching or moving away from the inner side of the lower die 2. And the rectangular slot 6 slidably connected to the rectangular slider 7 is designed such that one end faces the center of the lower die 2. Therefore, when the cylindrical slider 4 moves along the arc-shaped groove 3, the rectangular slider 7 installed on its top surface can be translated along a fixed direction towards the inner or outer side of the lower die 2, and the limit block 8 at the top of the rectangular slider 7 is driven to move towards the inner or outer side of the lower die 2 synchronously, thereby fixing the circular steel plate installed between the top of the ring-shaped base 5 and the plurality of limit blocks 8. Moreover, the plurality of arc-shaped grooves 3 are set at the same angle, and one end of each of the plurality of rectangular slots 6 is arranged towards the center of the lower die 2. So the speed and distance of each limit block 8 moving towards the inner side of the lower die 2 are synchronous. Thus, while fixing the circular steel plate, its center can be made to be directly opposite the center of the lower die 2, thereby realizing the rapid and accurate positioning of the circular steel plate, and further making the edge of the stamped pipe end cap flush, meeting the dimensional standard requirements of this component. A demoulding component is installed on the bottom surface of the base 1.

[0029] Wherein, a hydraulic jack 10 is installed below the fixed seat 11. The output end of the hydraulic jack 10 is installed with an upper die 9 that is used in cooperation with the lower die 2. The upper die 9 and the lower die 2 are concentrically arranged. Through the cooperation of the upper die 9, the hydraulic jack 10, and the fixed seat 11, the hydraulic jack 10 is driven to make the upper die 9 move downward to cooperate with the lower die 2 to stamp the circular steel plate into the required pipe end cap.

[0030] Among them, one side of the limiting block 8 facing the inner side of the lower die 2 is arc-shaped. By setting one side of the lower die 2 to be arc-shaped, the contact area with the edge of the circular steel plate to be stamped is increased, preventing wear on the edge of the circular steel plate during the positioning process and affecting the quality of the subsequent stamping of the pipe seal.

[0031] Among them, the inner wall of the annular base 5 is inclined, and the diameter of the inner wall at the bottom of the annular base 5 is the same as the inner diameter of the lower die 2. By adopting an inclined structure in which the diameter of the annular base 5 gradually increases from the bottom to the top, the annular steel plate can smoothly enter the interior of the lower die 2 during the stamping process, ensuring the normal progress of the stamping operation.

[0032] Among them, a handle 12 is fixedly installed on the outer wall of the annular base 5. By installing the handle 12 on the outer wall of the annular base 5, it is convenient for the staff to rotate the annular base 5, thereby driving the limiting block 8 to move and positioning the annular steel plate.

[0033] Among them, the demoulding assembly includes a plurality of hollow bases 13 fixedly installed on the lower surface below the top of the base 1. One side of each of the plurality of hollow bases 13 is provided with an opening. One end of each hollow base 13 with the opening faces the center of the lower die 2. A connecting block 14 is slidably connected inside the hollow base 13. A spring 15 is installed inside the hollow base 13. Both ends of the spring 15 abut against the connecting block 14 and the inner wall of the hollow base 13 respectively. A trapezoidal block 16 is installed on the side of the connecting block 14 away from the spring 15. One side of the trapezoidal block 16 away from the spring 15 passes through the center of the through hole of the hollow base 13. The end of the side of the trapezoidal block 16 that passes through is slidably connected to the top side wall of the upper die 9, and the end of the trapezoidal block 16 that passes through is inclined. By the combined use of the hollow base 13, the connecting block 14, the spring 15 and the trapezoidal block 16, when the upper die 9 and the lower die 2 perform stamping operations, the circular steel plate to be stamped and formed moves from the top to the bottom of the lower die 2 driven by the upper die 9, and then gradually fits with the trapezoidal block 16 below. One side of the trapezoidal block 16 that fits with it is an inclined surface, so the annular steel plate will gradually push the trapezoidal block 16 and make the connecting block 14 slide into the hollow base 13, while compressing the spring 15 at the same time. As the upper die 9 drives the annular steel plate to continue to move downward, the annular steel plate gradually moves away from the bottom of the lower die 2, and the connecting block 14 pushes the trapezoidal block 16 to approach the top side surface of the upper die 9 again under the action of the spring 15. After stamping, as the hydraulic ejector rod 10 drives the upper die 9 to retract, and since the diameter of the pipe head after stamping and forming is larger than the diameter of the upper die 9, the top surface of the pipe head fits with the bottom surface of the trapezoidal block 16, and under the reverse force of the trapezoidal block 16, the pipe head is separated from the surface of the upper die 9, thus realizing the demoulding of the pipe head without manual intervention, improving the operating efficiency of the device, and reducing the labor intensity of the operator.

[0034] Among them, a limiting ring is installed on the inner wall of the hollow base 13 at the opening. By installing the limiting ring at the opening of the hollow base 13, the connecting block 14 in the hollow base 13 can always slide within the hollow base 13, preventing the connecting block 14 from being pushed out of the hollow base 13 when the spring 15 rebounds and releases the compression force, thereby improving the reliability of the demolding assembly.

[0035] Specific usage method and function of the embodiment:

[0036] Before the installation and use of the present utility model, the staff needs to check the internal components or structures of the device. After the inspection is correct, it can be used normally. First, place the annular steel plate to be stamped on the top of the annular base 5, and then push the handle 12 to rotate the annular base 5, so as to position and fix the annular steel plate through the limiting block 8. Then, by means of an external controller, control the hydraulic jack 10 to push the upper die 9 close to the lower die 2 for stamping operation. When the stamping operation is completed, control the hydraulic jack 10 to retract. Under the action of the trapezoidal block 16 in the demolding assembly, as the upper die 9 gradually moves upward, the pipe head attached to the bottom surface thereof is detached. Through the above steps, the rapid positioning and fixing of the annular steel plate can be realized, the production efficiency is improved, and the pipe head after stamping can be automatically detached from the upper die 9, further improving the production efficiency and reducing the labor intensity of the operator.

[0037] The embodiments of the present utility model are given for the purposes of illustration and description. Although the embodiments of the present utility model have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present utility model. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present utility model.
