Description

Technical Field

[0001] This utility model belongs to the field of pipe bending technology, and in particular relates to a pipe bending device for the production of duct air conditioners. Background Technology

[0002] Ductless air conditioners, also known as ducted air conditioners, are small, all-air systems that use ducts to deliver air into the room. During the production of ductless air conditioners, the copper pipes need to be bent.

[0003] Existing pipe bending devices used in duct air conditioner manufacturing typically require limiting blocks to prevent copper pipe bending and deformation. However, when the copper pipe comes into contact with the limiting block, it experiences pressure on one side, causing changes in the pipe's roundness and making installation difficult. Therefore, we propose a pipe bending device for duct air conditioner manufacturing. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a pipe bending device for duct air conditioning production, enabling comprehensive limiting operation of copper pipes.

[0005] In view of this, the present invention provides a pipe bending device for duct air conditioner production, comprising a base, a servo motor fixedly connected to the inner wall of the base, a lead screw fixedly connected to the output end of the servo motor, a slider threadedly connected to the outer wall of the lead screw, a push seat welded to the top of the slider, a slide rail slidably connected to the outer wall of the push seat, a rotary cylinder fixedly connected to the top of the push seat, a pneumatic clamp fixedly connected to the output end of the rotary cylinder, a working cylinder fixedly connected to the top of the base, a sliding seat fixedly connected to the output end of the working cylinder, a limit cylinder fixedly connected to the top of the sliding seat, and a pusher fixedly connected to the output end of the limit cylinder. The push plate has limit rods welded to both ends. A limit groove is formed at the connection between the sliding seat and the limit rod. A movable limit block is fixedly connected to the outer wall of the push plate. A fixed limit block is fixedly connected to the top of the sliding seat and attached to the outer wall of the movable limit block. A pipe bending motor is fixedly connected to one end of the base. A rotating shaft is fixedly connected to the output end of the pipe bending motor. A pipe bending mold is fixedly connected to the top of the rotating shaft. A pipe bending frame is fixedly connected to the outer wall of the rotating shaft. A positioning cylinder is fixedly connected to one end of the pipe bending frame. A positioning seat is fixedly connected to the output end of the positioning cylinder. A positioning block that fits against the outer wall of the pipe bending mold is fixedly connected to the outer wall of the positioning seat.

[0006] Based on the above structure, the operation of the limiting cylinder drives the limiting rods at both ends of the push plate to slide along the groove of the limiting groove, so that the sliding of the push plate causes the movable limiting block to fit against the outer wall of the fixed limiting block, thereby realizing the limiting operation of the copper tube and preventing the copper tube from deforming when bending.

[0007] Preferably, the slide rail has a "T" shaped cross-section, and two sets of slide rails are provided. In this embodiment, the servo motor drives the push seat at the top of the slider to slide along the outer wall of the slide rail through the lead screw. By providing two sets of slide rails with a "T" shaped cross-section, the stability of the push seat sliding is improved. The sliding of the push seat drives the copper tube to slide synchronously, thereby enabling the bending operation of the copper tube at different positions.

[0008] Preferably, the central axis of the pneumatic clamp, the central axis of the fixed limiting block, and the central axis of the bending mold coincide. In this embodiment, the deformation of the copper tube during bending is avoided.

[0009] Preferably, the working surfaces of the movable limiting block, the fixed limiting block, and the positioning block are all provided with semi-circular grooves. In this embodiment, friction between the copper tube and the movable limiting block, the fixed limiting block, and the positioning block is avoided, which would cause scratches on the surface of the copper tube.

[0010] Preferably, the limiting rod forms a telescopic structure between the push plate and the limiting groove. In this embodiment, the operation of the limiting cylinder drives the limiting rods at both ends of the push plate to slide along the groove of the limiting groove, thereby realizing the stable sliding operation of the push plate.

[0011] Preferably, the movable limiting block and the fixed limiting block are located at the same height. In this embodiment, the push plate slides to cause the movable limiting block to fit against the outer wall of the fixed limiting block, thereby achieving the limiting operation of the copper tube and preventing the copper tube from deforming when bending.

[0012] Preferably, the positioning block forms a telescopic structure with the positioning seat and the bending mold, and the positioning block and the bending mold are at the same height. In this embodiment, the positioning cylinder works to drive the positioning block on the outer wall of the positioning seat to fit against the outer wall of the bending mold, fixing the copper tube to the outer wall of the bending mold. Then, the bending motor works to drive the rotating shaft to rotate, and the rotating shaft drives the bending mold and the positioning block to rotate synchronously, thereby performing the bending operation on the copper tube.

[0013] The beneficial effects of this utility model are: 1. This duct air conditioner production pipe bending device, by setting a movable limit block and a fixed limit block, the operation of the limit cylinder drives the limit rods at both ends of the push plate to slide along the groove of the limit groove, so that the push plate slides and drives the movable limit block to fit against the outer wall of the fixed limit block, thereby realizing the limit operation of the copper pipe and preventing the copper pipe from deforming during bending.

[0014] 2. The pipe bending device for air conditioning duct production uses a sliding seat. The working cylinder drives the movable limit block and the fixed limit block at the top of the sliding seat to slide along the top of the base, which prevents the copper pipe from rubbing against the movable limit block and the fixed limit block during bending, thus avoiding damage to the outer wall of the copper pipe.

[0020] Based on the above structure, the operation of the limiting cylinder 11 drives the limiting rods 13 at both ends of the push plate 12 to slide along the groove of the limiting groove 14, so that the push plate 12 slides and drives the movable limiting block 15 to fit against the outer wall of the fixed limiting block 16, thereby realizing the limiting operation of the copper tube and preventing the copper tube from deforming when bending.

[0021] In one embodiment, the slide rail 6 has a "T" shaped cross-section, and two sets of slide rail 6 are provided.

[0022] In this embodiment, the servo motor 2 drives the push seat 5 at the top of the slider 4 to slide along the outer wall of the slide rail 6 via the lead screw 3. By setting two sets of slide rails 6 with a "T" shaped cross section, the stability of the push seat 5 sliding is improved. The sliding of the push seat 5 drives the copper tube to slide synchronously, thereby performing bending operations on the copper tube at different positions.

[0023] In one embodiment, the central axis of the pneumatic clamp 8, the central axis of the fixed limiting block 16, and the central axis of the pipe bending mold 19 coincide.

[0024] In this embodiment, deformation of the copper tube is avoided during bending.

[0025] In one embodiment, the working surfaces of the movable limiting block 15, the fixed limiting block 16, and the positioning block 23 are all provided with semi-circular grooves.

[0026] In this embodiment, friction between the copper tube and the movable limiting block 15, the fixed limiting block 16 and the positioning block 23 is avoided to prevent scratches from appearing on the surface of the copper tube.

[0027] In one embodiment, the limiting rod 13 forms a telescopic structure between the push plate 12 and the limiting groove 14.

[0029] In one embodiment, the movable limiting block 15 and the fixed limiting block 16 are located at the same height.

[0030] In this embodiment, the push plate 12 slides to cause the movable limiting block 15 to fit against the outer wall of the fixed limiting block 16, thereby limiting the copper tube and preventing the copper tube from deforming when bending.

[0031] In one embodiment, the positioning block 23 forms a telescopic structure with the bending mold 19 via the positioning seat 22, and the positioning block 23 and the bending mold 19 are at the same height.

[0034] Next, the servo motor 2 drives the pusher seat 5 at the top of the slider 4 to slide along the outer wall of the slide rail 6 via the lead screw 3. The sliding of the pusher seat 5 causes the copper tube to slide synchronously, thereby performing bending operations on the copper tube at different positions.

[0035] Next, the limiting cylinder 11 operates to drive the limiting rods 13 at both ends of the push plate 12 to slide along the groove of the limiting groove 14, so that the push plate 12 slides and drives the movable limiting block 15 to fit against the outer wall of the fixed limiting block 16, thereby realizing the limiting operation of the copper tube and preventing the copper tube from deforming when bending.

[0036] Next, the positioning cylinder 21 operates, causing the positioning block 23 on the outer wall of the positioning seat 22 to fit against the outer wall of the bending mold 19, fixing the copper tube to the outer wall of the bending mold 19. Then, the bending motor 17 operates, driving the rotating shaft 18 to rotate. The rotation of the rotating shaft 18 causes the bending mold 19 and the positioning block 23 to rotate synchronously, thereby performing the bending operation on the copper tube. At the same time, the working cylinder 9 operates, causing the movable limiting block 15 and the fixed limiting block 16 at the top of the sliding seat 10 to slide along the top of the base 1, preventing the copper tube from rubbing against the movable limiting block 15 and the fixed limiting block 16 during bending, which could damage the outer wall of the copper tube.
