Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe fitting processing, in particular to a PE pipe fitting welding device. Background Art

[0002] PE pipe fittings have locking hoops, stepped annular sealing rings and other components inside. PE pipe fittings are easy to disassemble, flexible, easy to recycle, beautiful and practical, strong and good sealing, and are widely used in the transportation industry.

[0003] During the use of PE pipe fittings, it is often necessary to connect two PE pipe fittings to form a mutually connected conduit so that the two PE pipe fittings can be transported over long distances after being connected. At present, when welding PE pipe fittings, the operator will place the PE pipe fittings in a U-shaped holder, squeeze the PE pipe fittings through the upper and lower U-shaped holders, and then use bolts to connect the two U-shaped holders, place the heating plate between the two PE pipe fittings, and then use the matching guide rails and sliders to allow the two PE pipe fittings to contact the heating plate when moving. After the heating plate heat-melts the connection between the two PE pipe fittings, the heating plate is taken out and the two PE pipe fittings are connected. The E pipe fittings are welded after being butt-jointed with each other, and this processing method has the following shortcomings when used: since the specifications of the U-shaped clamp are fixed and cannot be adjusted, the U-shaped clamp can only limit the PE pipe fittings of one specification. If PE pipe fittings of different specifications are encountered, the operator needs to change the welding equipment, which not only increases the operator's work intensity, but also affects the efficiency of welding PE pipe fittings; and because PE pipe fittings will produce a large amount of gas during hot melting, and the welding equipment does not seal the PE pipe fittings during welding, the gas overflows and affects the surrounding environment, and the operator's safety during operation cannot be guaranteed. Utility Model Content

[0004] The utility model aims to solve the problem that welding equipment in the prior art can only limit the position of PE pipe fittings of one specification, and proposes a PE pipe fitting welding device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A PE pipe welding device comprises a base, a guide rail, a slider, and a heating plate. A support with a through hole is fixedly mounted on the slider, and a symmetrically arranged sleeve is fixedly mounted on the support. A limit assembly for limiting the PE pipe is installed in the sleeve. A bracket is fixedly mounted on the base, and a hydraulic cylinder is fixedly mounted on the bracket. A traction rod is fixedly connected to the output end of the hydraulic cylinder. The heating plate is arranged on the traction rod. A protective cover is fixedly mounted on the support, and a suction fan is arranged on the protective cover. A sliding sleeve is arranged on the traction rod, and a sealing cover matching the protective cover is fixedly mounted on the sliding sleeve.

[0007] Preferably, the limiting assembly includes a motor fixedly installed in the sleeve, and a screw rod is fixedly connected to the output end of the motor, a matching nut is slidably sleeved on the screw rod, and a pressure rod is fixedly installed on the nut, and a limiting plate that is movably opposed to the PE pipe fitting is integrally connected to the pressure rod.

[0008] Preferably, the screw rod is arranged horizontally, the limiting plate and the pressure rod extend to one side of the through hole, and the limiting plate is an arc-shaped structure adapted to the PE pipe fitting.

[0009] Preferably, the protective cover is a U-shaped structure with an opening on one side, and the sealing cover is a U-shaped structure with an opening on the bottom.

[0010] Preferably, a locking bolt detachably connected to the traction rod is threadedly connected to the sliding sleeve, a sealing opening corresponding to the sealing cover is opened on the protective cover, and a silicone pad corresponding to the sealing opening is embedded on the sealing cover.

[0011] Compared with the prior art, the utility model has the following advantages:

[0012] 1. The utility model drives the motor to enable two limit plates to limit the PE pipe fittings from both sides, which can increase the contact area between the limit plates and the PE pipe fittings. The limit plates can limit the PE pipe fittings of different specifications when moving, so that the welding equipment does not need to be replaced when welding PE pipe fittings of different specifications, thereby reducing the work intensity of the operator.

[0013] 2. The utility model enables the protective cover to correspond to the sealing cover when moving toward each other, so that the protective cover and the sealing cover can collect the gas generated during the processing of the PE pipe fittings, and prevent the gas from overflowing due to failure to collect the gas, which not only protects the surrounding environment, but also ensures the safety of the operator during operation.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-Figure 3 A PE pipe welding device comprises a base 1, a guide rail, a slider, and a heating plate. A support 2 with a through hole is fixedly mounted on the slider, and a symmetrically arranged sleeve 3 is fixedly mounted on the support 2;

[0020] A limiting assembly for limiting the position of the PE pipe fitting is installed in the sleeve 3;

[0021] The limiting assembly includes a motor 4 fixedly installed in the sleeve 3, and a screw 5 is fixedly connected to the output end of the motor 4, a matching nut 6 is slidably sleeved on the screw 5, and a pressure rod is fixedly installed on the nut 6. The two limiting plates 7 can limit the PE pipe fittings when they move through the drive of the motor 4, so that the two limiting plates 7 can limit the PE pipe fittings of different specifications when they move toward each other, thereby increasing the adaptability of the welding equipment;

[0022] The pressure rod is integrally connected with a limit plate 7 that is movably opposed to the PE pipe fitting, the screw rod 5 is horizontally arranged, the limit plate 7 and the pressure rod extend to one side of the through hole, and the limit plate 7 is an arc-shaped structure that matches the PE pipe fitting. By setting the limit plate 7 to an arc-shaped structure that matches the PE pipe fitting, the contact degree between the limit plate 7 and the PE pipe fitting can be increased, and the efficiency of welding the PE pipe fitting can be effectively improved;

[0023] A bracket 9 is fixedly mounted on the base 1, and a hydraulic cylinder 10 is fixedly mounted on the bracket 9. A traction rod 11 is fixedly connected to the output end of the hydraulic cylinder 10. The heating plate is arranged on the traction rod 11. A protective cover 8 is fixedly mounted on the support 2, and a suction fan is arranged on the protective cover 8. The suction fan can collect the gas generated during the welding of PE pipe fittings.

[0024] A sliding sleeve 12 is provided on the traction rod 11, and a sealing cover 13 matching with the protective cover 8 is fixedly installed on the sliding sleeve 12. The protective cover 8 is a circular structure with one side opening, and the sealing cover 13 is a circular structure with a bottom opening. A locking bolt detachably connected to the traction rod 11 is threadedly connected to the sliding sleeve 12. A sealing port 14 corresponding to the sealing cover 13 is provided on the protective cover 8, and a silicone pad corresponding to the sealing port 14 is embedded on the sealing cover 13 (the silicone pad is not shown in the drawings of the specification);

[0025] Supplementary explanation: when the two protective covers 8 move toward each other, the heating plate can contact the PE pipe fitting, and the silicone pad can make initial contact with the sealing port 14;

[0026] When the two PE pipes move toward each other again, the heating plate rises to the specified position and disconnects from the protective cover 8. By adjusting the position of the sliding sleeve 12, the sealing port 14 can squeeze the silicone pad when the two protective covers 8 move toward each other, so that the gas generated by the PE pipe during welding will not be inhaled by the operator, thereby protecting the operator's safety;

[0027] It should be noted that the specific models and specifications of the heating plate, guide rails, sliders, motor 4, and suction fan need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it is not repeated here.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Place two PE pipes on both sides of the base 1 and extend them into the support 2 through the through holes;

[0030] The output end of the motor 4 drives the screw rod 5 to rotate, and the screw rod 5 drives the nut 6 to slide when rotating, so that the nut 6 drives the pressure rod and the limit plate 7 to move when sliding in the sleeve 3, so that the limit plate 7 limits the PE pipe fitting from both sides;

[0031] When the PE pipe is limited, the motor 4 is turned off;

[0032] The output end of the hydraulic cylinder 10 drives the traction rod 11 to move downward, and the traction rod 11 drives the sliding sleeve 12 and the heating plate to move downward when moving downward, so that the heating plate can be located between the two PE pipe fittings;

[0033] The matched guide rails and sliders are opened by an external device, so that the two sliders drive the two supports 2 and the two protective covers 8 to move when they move toward each other, and the support 2 drives the PE pipe fittings to contact the heating plate when moving;

[0034] At the same time, the two protective covers 8 can seal the PE pipe fitting and the heating plate when they move relative to each other. The sliding sleeve 12 drives the sealing cover 13 to move downward when it moves downward, so that the sealing cover 13 can extend between the two protective covers 8, so that the sealing cover 13 drives the silicone pad to initially fit with the sealing port 14.

[0035] The heating plate can heat-melt the two PE pipes after being turned on, and the suction fan can collect the gas generated during processing;

[0036] After the heating plate is hot-melted on the PE pipe fitting, the locking bolt is removed to disconnect the sliding sleeve 12 from the traction rod 11. The output end of the hydraulic cylinder 10 drives the traction rod 11 and the heating plate to move upward. When the heating plate rises to a certain position, the locking bolt is used to connect the sliding sleeve 12 and the traction rod 11, and the sealing cover 13 can be located between the two sealing ports 14.

[0037] The slider is opened through an external device, so that the slider moves toward each other to drive the two PE pipe fittings to contact each other. When the slider moves, it drives the support 2 and the protective cover 8 to move, so that the protective cover 8 can apply pressure to the silicone pad when moving. After the PE pipe fittings are in contact for a period of time, the interface solidifies to achieve welding.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
