Description

Technical Field

[0001] The utility model relates to the field of metal pipe processing, in particular to a pipe mouth extrusion device. Background Art

[0002] In oilfield development, in order to protect key gate and valve group equipment, it is usually necessary to install protective piles at the valve group location. During the production and installation of protective piles, by pre-flattening the pipe mouth and then docking it vertically with the pipeline, the gap during welding can be reduced, thereby reducing welding defects such as porosity and lack of fusion, and improving welding quality. Currently, the widely used physical impact pipe mouth forming methods include manual hammering and mechanical pipe mouth extrusion. However, manual hammering relies on the operator's physical strength, has high labor intensity, low efficiency, and poses safety hazards. Although the mechanical pipe mouth extrusion device improves the forming efficiency and safety through mechanical force, it has a cumbersome operation process due to the complex structure of the device.

[0003] The existing physical impact nozzle forming method has technical problems such as high labor intensity, low labor efficiency and safety risks due to reliance on manual hammering, as well as cumbersome operation due to complex structure. Utility Model Content

[0004] The purpose of the utility model is to provide a pipe mouth extrusion device to alleviate the technical problems in the related technology such as high labor intensity, low labor efficiency and safety risks caused by reliance on manual hammering, as well as cumbersome operation due to complex structure.

[0005] In order to solve the above technical problems, the technical solution provided by the present invention is:

[0006] The pipe orifice extrusion device provided by the utility model comprises:

[0007] The fixed end comprises a platform and a first extrusion unit mounted on the platform. The movable end comprises a second extrusion unit hingedly connected to the first extrusion unit. The first extrusion unit, the platform, and the second extrusion unit form an extrusion molding area. The second extrusion unit swings about the first extrusion unit, shrinking the extrusion molding area to extrude the prefabricated tube.

[0008] Specifically, the first extrusion unit includes a first extrusion component. The second extrusion unit includes a second extrusion plate. The first extrusion component is mounted on the platform, and the second extrusion plate is rotatably connected to the first extrusion component. The first extrusion component, the platform, and the second extrusion plate define the extrusion molding area.

The first extrusion component comprises a first extrusion plate and a side plate, which is arranged perpendicularly to the first extrusion plate. The through bolt is inserted into the side plate, and the second extrusion plate is rotationally connected to the through bolt. The first extrusion plate, the side plate, the platform and the second extrusion plate enclose the extrusion forming area, and the swing of the second extrusion plate around the first extrusion plate reduces the extrusion forming area.

[0010] Specifically, the first extrusion unit further comprises a first extrusion block. The second extrusion unit further comprises a second extrusion block. The first extrusion block and the second extrusion block are arranged on the side of the first extrusion plate and the second extrusion plate, respectively, which are close to each other. The first extrusion block, the side plate, the platform and the second extrusion block enclose the extrusion forming area.

[0011] Specifically, the second extrusion unit further comprises an operating handle, which is connected to the second extrusion plate and used to drive the second extrusion plate to swing around the through bolt.

[0012] Specifically, the second extrusion unit further comprises an elongated rod, which is sleeved to the end of the operating handle away from the second extrusion plate.

[0014] Specifically, the first extrusion component is provided with a notch, which is used to avoid the passage of the prefabricated pipe along the length direction of the through bolt into the extrusion forming area.

[0015] Specifically, a reinforcing rib is arranged between the first extrusion plate and the platform. A reinforcing rib is arranged between the second extrusion plate and the operating handle.

[0016] Specifically, it further comprises a support frame, and the platform is mounted on the support frame.

[0017] The beneficial effects of the above technical solutions are analyzed as follows:

[0018] The utility model provides a kind of pipe mouth extrusion device, comprising:

[0019] Fixed end and movable end. The fixed end includes a platform and a first extrusion unit mounted on the platform. The movable end includes a second extrusion unit hinged to the first extrusion unit. The first extrusion unit, the platform and the second extrusion unit enclose an extrusion forming area, and the swing of the second extrusion unit around the first extrusion unit reduces the extrusion forming area to extrude the prefabricated pipe.

[0020] In specific applications, the prefabricated tube is inserted into the extrusion molding area along the direction of the hinge axis between the second extrusion unit and the first extrusion unit, and the second extrusion unit is swung around the first extrusion unit to shrink the extrusion molding area, thereby applying a closed extrusion action to the prefabricated tube, thereby completing a stable and controllable tube mouth molding operation.

[0021] As can be seen, compared to the existing technology, this nozzle extrusion device reduces the extrusion molding area by swinging the hinged second extrusion unit relative to the first extrusion unit, thereby applying extrusion to the prefabricated tube and achieving a stable and controllable nozzle molding operation. This overcomes the technical problems of existing physical impact nozzle molding methods, such as high labor intensity, low labor efficiency, and safety risks caused by relying on manual hammering, as well as cumbersome operation due to complex structure.

[0030] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0032] The following embodiments of the present invention are described in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0033] The existing physical impact nozzle forming method has technical problems such as high labor intensity, low labor efficiency and safety risks due to reliance on manual hammering, as well as cumbersome operation due to complex structure.

[0034] In view of this, the present invention provides a pipe orifice extrusion device, comprising:

[0035] The fixed end 100 and the movable end 200 are shown. The fixed end 100 includes a platform 120 and a first extrusion unit 110 mounted on the platform 120. The movable end 200 includes a second extrusion unit 210 hingedly connected to the first extrusion unit 110. The first extrusion unit 110, the platform 120, and the second extrusion unit 210 form an extrusion molding area. The swinging of the second extrusion unit 210 around the first extrusion unit 110 shrinks the extrusion molding area to extrude the prefabricated tube.

[0036] Based on the above technical solutions, the pipe orifice extrusion device provided by the present invention can achieve the following technical effects:

[0037] This nozzle extrusion device reduces the extrusion molding area by swinging the hinged second extrusion unit 210 relative to the first extrusion unit 110, thereby applying extrusion to the preformed pipe and achieving a stable and controllable nozzle molding operation. This overcomes the technical problems of existing physical impact nozzle molding methods, such as high labor intensity, low labor efficiency, and safety risks caused by manual hammering, as well as cumbersome operation due to complex structure.

[0038] The following combination Figures 1 to 3 The structure and shape of the nozzle extrusion device provided in this embodiment are described in detail:

[0039] In this embodiment, the first extrusion unit 110 includes a first extrusion component 111. The second extrusion unit 210 includes a second extrusion plate 211. The first extrusion component 111 is mounted on the platform 120, and the second extrusion plate 211 is rotatably connected to the first extrusion component 111. The first extrusion component 111, the platform 120, and the second extrusion plate 211 form an extrusion molding area. The swinging of the second extrusion plate 211 around the first extrusion component 111 shrinks the extrusion molding area, thereby squeezing the prefabricated tube within the extrusion molding area.

[0040] In the solution of this embodiment, the first extrusion unit 110 also includes a through-pin bolt 112. The first extrusion component 111 includes a first extrusion plate 1111 and a side plate 1112, with the side plate 1112 being arranged perpendicular to the first extrusion plate 1111. The through-pin bolt 112 is inserted into the side plate 1112, and the second extrusion plate 211 is rotatably connected to the through-pin bolt 112. The first extrusion plate 1111, the side plate 1112, the platform 120, and the second extrusion plate 211 form an extrusion molding area. The swinging of the second extrusion plate 211 around the first extrusion plate 1111 shrinks the extrusion molding area, thereby squeezing the prefabricated tubes within the extrusion molding area.

[0041] In the solution of this embodiment, the first extrusion unit 110 also includes a first extrusion block 113. The second extrusion unit 210 also includes a second extrusion block 212. The first extrusion block 113 and the second extrusion block 212 are respectively arranged on the side where the first extrusion plate 1111 and the second extrusion plate 211 are close to each other. The first extrusion block 113, the side plate 1112, the platform 120 and the second extrusion block 212 form an extrusion molding area. The swing of the second extrusion plate 211 around the first extrusion plate 1111 is used to drive the first extrusion block 113 and the second extrusion block 212 abutting on both sides of the prefabricated pipe to extrude the prefabricated pipe in the extrusion molding area. Among them, the thickness of the first extrusion block 113 and the second extrusion block 212 in the length direction of the through-pin bolt 112 is used to adjust the extrusion molding length of the prefabricated pipe mouth.

[0042] In the solution of this embodiment, the second extrusion unit 210 further includes an operating handle 220 . The operating handle 220 is connected to the second extrusion plate 211 and is used to drive the second extrusion plate 211 to swing around the through-pin bolt 112 .

[0043] In order to further increase the torque used, in the solution of this embodiment, the second extrusion unit 210 further includes an extension rod 230 , which is sleeved on the end of the operating handle 220 away from the second extrusion plate 211 .

[0044] In the solution of this embodiment, the first extrusion unit 110 further includes a washer 130 , which is disposed on the platform 120 and abuts against the prefabricated pipe, and is used to adjust the distance between the prefabricated pipe and the through-pin bolt 112 to adjust the extrusion force on the prefabricated pipe.

[0045] In order to prevent the side plate 1112 from blocking the prefabricated tube, in the solution of this embodiment, the first extrusion component 111 is provided with a notch, which is used to avoid the prefabricated tube from entering the extrusion molding area along the length direction of the through-pin bolt 112.

[0046] In order to improve the strength and stability of the nozzle extrusion device, in the solution of this embodiment, a reinforcing rib is provided between the first extrusion plate 1111 and the platform 120 , and a reinforcing rib is provided between the second extrusion plate 211 and the operating handle 220 .

[0047] In order to facilitate the operation of the operator, match the height, and avoid frequent bending, the solution of this embodiment further includes a support frame 300, and the platform 120 is installed on the support frame 300.

[0048] In summary, the specific working process of the nozzle extrusion device provided in this embodiment is as follows:

[0049] An operator holds the extension rod 230 and lifts it up to drive the second extrusion plate 211 to swing around the through-pin bolt 112 in a direction away from the first extrusion plate 1111 , thereby separating the second extrusion block 212 from the first extrusion block 113 .

[0050] Another operator holds the prefabricated tube and inserts it into the extrusion molding area along the length of the through-pin bolt 112, and makes the prefabricated tube flush with the second extrusion block 212 and the first extrusion block 113. The operator holding the extension rod 230 applies downward pressure to drive the second extrusion plate 211 to swing around the through-pin bolt 112 toward the first extrusion plate 1111, thereby driving the first extrusion block 113 and the second extrusion block 212 abutting on both sides of the prefabricated tube to squeeze the prefabricated tube in the extrusion molding area, and the extrusion force compresses the tube mouth from a round shape to an oblate shape. The molding extrusion action is completed in the encirclement of the first extrusion plate 1111, the side plate 1112, the second extrusion plate 211 and the platform 120. The entire molding extrusion process is stable and highly controllable.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
