Description

Technical Field

[0001] This utility model belongs to the field of pressure welding technology, and in particular relates to a pressure welding device. Background Technology

[0002] Pressure welding is a special welding process that uses pressure assistance combined with heating or plastic deformation to achieve a connection. The core is to use pressure to bring the metal of the part to be welded to a plastic state, which promotes atomic diffusion at the contact surface and forms metal bonds. At the same time, it is often used in conjunction with prefabricated welding materials to wrap the target area for welding. It is mainly used for repairing pipeline corrosion, leakage and other faults, or for connecting parts that require precise alignment and are not resistant to high temperatures. During construction, it is necessary to first clean the impurities on the surface to be welded, do a good job of sealing and plugging leaks, and then fix it with clamps and complete the work by wrapping and welding in sections.

[0003] When welding cylindrical metal parts, it is necessary to compress and connect them with grooves that correspond to their shape to ensure that the shape remains unchanged after welding. Since there are many types of cylindrical welded parts, it is troublesome to use multiple molds for switching operations. It is necessary to find and install the molds, which makes the mold switching operation of conventional pressure welding equipment quite troublesome.

[0004] Therefore, we propose a welding device with a pressure vessel to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the mold switching operation of conventional pressure welding devices is relatively troublesome, and to propose a pressure welding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A welding device with a pressure plate includes a body. A hydraulic rod is fixedly mounted on the upper part of the body. A bearing is fixedly connected to the lower end of the hydraulic rod and the body. A polygonal block is rotatably mounted on the bearing. A pin is slidably mounted on the bearing and is movably inserted into the polygonal block. A spring is movably sleeved around the pin. One end of the spring is fixedly connected to the bearing, and the other end is fixedly connected to the pin. Pulling the pin outward disengages it from the polygonal block. Then, rotating the polygonal block switches the pressing surface, simultaneously matching and switching to another polygonal block. This facilitates switching according to the type of metal rod, increasing the welding matching capability.

[0007] Preferably, the bearing includes a base, and a bearing is fixedly mounted on the upper end of the base. One bearing base is fixedly connected to the machine body, and the other bearing base is fixedly connected to a hydraulic rod. The bearing guides the polygonal block to rotate, and the extrusion surface is switched by rotating the polygonal block.

[0008] Preferably, the base has a through hole. The through hole is used to guide the sliding of the plug.

[0009] Preferably, the polygonal block includes a block body with an insertion hole inside. The block body is rotatably mounted on a shaft, and a groove is formed on the outer periphery of the block body. The groove of the pressed surface is switched by rotating the block body.

[0010] Preferably, the outer end of the socket has a guide opening. The guide opening guides the plug into the socket, and facilitates the insertion of the plug into the angle of the locking polygonal block.

[0011] Preferably, the plug includes a plug body, which is slidably installed within the through hole or insertion hole. A pull button is fixedly connected to one end of the plug body, and a spring is movably sleeved around the plug body. One end of the spring is fixedly connected to the pull button, and the other end is fixedly connected to the base. The spring's elastic force acts on the pull button, causing the pull button to act on the plug body, thus keeping the plug body within the insertion hole or through hole.

[0012] Preferably, the plug further includes a guide head, which is fixedly connected to one end of the plug body. The guide head guides the plug body into the guide port and the insertion hole.

[0013] In summary, the technical effects and advantages of this utility model are as follows: Pull the plug outward to disengage it from the polygonal block, then rotate the polygonal block to switch the extrusion surface of the polygonal block, and simultaneously match and switch another polygonal block. This facilitates switching according to the model of the metal rod and increases the welding matching rate. Attached Figure Description

A spring 5 is movably sleeved outside the plug body 41, with one end fixedly connected to the pull button 43 and the other end fixedly connected to the seat 21. The spring force of the spring 5 acts on the pull button 43, causing the pull button 43 to act on the plug body 41, thus keeping the plug body 41 within the insertion hole 33 and the through hole 22.

[0023] like Figure 1 , 3 As shown in Figure 4, the plug 4 also includes a guide head 42, which is fixedly connected to one end of the plug body 41. The guide head 42 is used to guide the plug body 41 into the guide port 34 and the insertion hole 33.
