Description

Technical Field

[0001] This utility model relates to the field of volute production technology, and in particular to a welding beveling device for volute production. Background Technology

[0002] During the production of the volute casing, sheet metal needs to be rolled into a ring. Welding is then performed at the joint of the ring-shaped sheet metal. Before welding, the edges of the sheet metal need to be beveled. Beveling welding involves pre-cutting cracks and holes on the edge of the joint to weaken its tensile strength, allowing molten welding material to fill them. This greatly reduces welding stress and prevents warping deformation during processing.

[0003] Both ends of the sheet metal must be beveled. Therefore, the beveling is usually done before the sheet metal is rolled up, which gives the operator more room to work. After rolling, the two bevels are joined at the joint. Since the ends of the sheet metal are beveled separately, the force and angle cannot be completely uniform. If the error is too large, the welding material cannot be evenly filled during welding, resulting in an excessively large weld or a hollow weld. Utility Model Content

[0004] The purpose of this application is to provide a welding beveling device for volute production to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: A welding beveling device for producing volute casings includes a workbench and a beveling assembly mounted on the workbench. The beveling assembly includes a functional plate, a lifting plate, and a support plate. The lifting plate is movably mounted on the workbench surface. Two support plates are symmetrically mounted on the workbench surface, positioned between the lifting plate and the workbench. The functional plate is movably mounted on the surface of the lifting plate and is T-shaped. Beveling machines are fixedly mounted on both sides of the functional plate. Support blocks are fixedly mounted at both ends of the workbench surface, and both ends of the lifting plate rest on the support blocks. Cylinders are fixedly mounted above both sides of the workbench surface, and clamping blocks are fixedly mounted on the output ends of both sets of cylinders. One end of each clamping block has a concave arc surface.

[0006] Preferably, two motors are fixedly mounted on the surface of the lifting plate. A screw is fixedly mounted on the output end of each motor, and one end of the screw is connected to the surface of the lifting plate via a bearing. Connecting plates are fixedly mounted on the outer walls of both sides of the lower portion of the functional plate. A slider is fixedly mounted on the end of each connecting plate, and the slider is threaded onto the screw. The end of the support plate is U-shaped. A second motor is fixedly mounted on the surface of the worktable, and the output end of the second motor is fixedly connected to the bottom end of the support plate. The outer wall of the U-shaped end of the support plate is in contact with the bottom surface of the lifting plate. An opening is formed at the end of the lifting plate, and a fixing rod is fixedly mounted on the top surface of the support block. The fixing rod passes through the opening in the lifting plate, and a spring is sleeved on the outside of the fixing rod.

[0007] The beneficial effects of this utility model are: by providing a beveling component, both ends of the joint of the rolled ring plate can be beveled simultaneously, improving the uniformity of the bevel at the weld and reducing the risk of excessively large welds or hollowed-out welds.

[0011] like Figure 1-4The illustrated welding beveling device for producing volute casings includes a workbench 1 and a beveling assembly mounted on the workbench 1. The beveling assembly includes a functional plate 8, a lifting plate 2, and a support plate 12. The lifting plate 2 is movably mounted on the surface of the workbench 1. Two support plates 12 are symmetrically mounted on the surface of the workbench 1, positioned between the lifting plate 2 and the workbench 1. The functional plate 8 is movably mounted on the surface of the lifting plate 2 and is T-shaped. Beveling machines are fixedly mounted on both sides of the functional plate 8. Support blocks 7 are fixedly mounted at both ends of the workbench 1, and both ends of the lifting plate 2 are placed on the support blocks 7. Cylinders 11 are fixedly mounted above both sides of the workbench 1, and clamping blocks 10 are fixedly mounted on the output ends of both sets of cylinders 11. One end of the clamping block 10 has a concave arc surface.

[0012] Two motors 3 are fixedly mounted on the surface of the lifting plate 2. A screw 4 is fixedly mounted on the output end of each motor 3, and one end of the screw 4 is connected to the surface of the lifting plate 2 via a bearing. Connecting plates 9 are fixedly mounted on the outer walls of both sides of the lower part of the functional plate 8. A slider is fixedly mounted on the end of the connecting plate 9, and the slider is threaded onto the screw 4. The end of the support plate 12 is U-shaped. A motor 13 is fixedly mounted on the table surface of the worktable 1. The output end of the motor 13 is fixedly connected to the bottom end of the support plate 12. The outer wall of the U-shaped end of the support plate 12 is flush with the bottom surface of the lifting plate 2. An opening is made at the end of the lifting plate 2. A fixing rod 5 is fixedly mounted on the top surface of the support block 7, passing through the opening in the lifting plate 2. A spring 6 is sleeved around the outside of the fixing rod 5.

[0013] Example: After the sheet material is rolled into a ring, it is placed between two clamping blocks 10 on the workbench 1. The cylinder 11 is started and pushes the clamping blocks 10, which clamp the ring material. The vertical plate of the functional plate 8 is located in the gap of the ring material. Beveling machines are installed on both sides of the horizontal plate. The beveling machines are in contact with the edge of the sheet material. Then, the two motors 3 are started, driving the screw 4 to rotate. The screw 4 drives the slider to move, the slider drives the connecting plate 9 to move, and the connecting plate 9 drives the functional plate 8 to move. The functional plate 8 is T-shaped. The beveling machine of the functional plate 8 beveles the edge of the sheet material. During the movement of the functional plate 8, the vertical plate can separate the gap of the ring material and separate the tightly attached parts.

[0014] To accommodate ring-shaped plates of different sizes, after the two clamping blocks 10 clamp the plates, the motor 13 drives the support plate 12 to rotate. The end of the support plate 12 is U-shaped, and the arc surface of the end of the support plate 12 contacts the bottom surface of the lifting plate 2. When the support plate 12 flips, it lifts the lifting plate 2. When the lifting plate 2 is lifted, the fixing rod 5 on the support block 7 provides guidance, the spring 6 is compressed and deformed, and the spring 6 provides resistance to help the lifting plate 2 run smoothly. The lifting plate 2 drives the functional plate 8 to move at the gap of the ring-shaped plate, so that the bevel assembly can process ring-shaped plates of different sizes.
