Description

Technical Field

[0001] This utility model relates to the field of beveling technology, specifically a beveling cutting device for seamed elbows. Background Technology

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example: Please refer to Figure 1 and Figure 2 This utility model provides a beveling cutting device for seamed elbows, including a hollow base 1, a clamping seat 2 fixedly disposed on the bottom inner wall of the hollow base 1, a clamping plate 3 disposed directly above the clamping seat 2 and together with the clamping seat 2 clamping the seamed elbow, a first linear actuator 4 fixedly disposed on the top inner wall of the hollow base 1 and driving the clamping plate 3 to move longitudinally, a bracket 5 fixedly disposed on the left and right sides of the clamping seat 2, a beveling machine 6 disposed above the bracket 5 and aligned with the center axis of the end face of the seamed elbow, and a second linear actuator 7 fixedly disposed on the bracket 5 and driving the beveling machine 6 to feed linearly toward the center axis of the end face of the seamed elbow.

[0020] The slotted elbow in this utility model is a 90° elbow. Please refer to [link / reference]. Figure 3 The upper surface of the clamping seat 2 has a lower groove 8 that matches the outer arc segment of the seam elbow, and the lower surface of the clamping plate 3 has an upper groove 9 that matches the inner arc segment of the seam elbow. The clamping seat 2 and the clamping plate 3 can respectively abut and clamp the outer arc segment and the inner arc segment of the seam elbow, so that the central axes of the two end faces of the seam elbow are tilted at an angle of 45° towards the upper left and upper right corners respectively. The first linear actuator 4 is a ball screw type electric push rod, and the push rod end of the first linear actuator 4 is fixedly connected to the upper surface of the clamping plate 3. This utility model adapts to seam elbows of different specifications by changing the specifications of the clamping seat 2 and the clamping plate 3.

[0021] The upper surface of the bracket 5 is a downward-sloping 45° inclined plane. The upper surface of the bracket 5 is fixedly connected to the base of the second linear actuator 7. The second linear actuator 7 is a ball screw type electric module, and the slider end of the second linear actuator 7 is bolted to a mounting bracket. The beveling machine 6 consists of a motor and a beveling cutter fixed on the motor output shaft. The motor and the mounting bracket are bolted together. This utility model adjusts the distance between the motor and the slider end of the second linear actuator 7 by changing the position of the motor on the mounting bracket, allowing the beveling machine 6 to properly align the end faces of seamed elbows of different specifications.

[0022] This invention uses two beveling machines 6 arranged symmetrically to simultaneously bevele the two end faces of the welded elbow, ensuring symmetry and precision, reducing repeated clamping, positioning and downtime of the welded elbow, and the symmetrical processing offsets the radial force generated by unilateral cutting, reducing the risk of deformation (especially for thin-walled elbows) and lowering the scrap rate.

[0023] Please see Figure 4 In the above embodiment, cantilever plates 11 are fixedly provided on both the left and right sidewalls of the clamping plate 3. A clamping plate 12 is hinged to the end of the cantilever plate 11 away from the clamping plate 3. A rubber plug 13 adapted to the port of the slotted elbow is fixedly provided on the lower surface of the clamping plate 12, and a handle 14 is fixedly provided on the upper surface of the clamping plate 12. A first limiting plate 15 is fixedly provided on the upper surface of the cantilever plate 11. A first magnetic block 16 magnetically attracted to the clamping plate 12 is fixedly provided on the first limiting plate 15. When the first magnetic block 16 magnetically attracts the clamping plate 12, the clamping plate 12 is perpendicular to the clamping plate 12. In addition, a second limiting plate 17 is fixedly provided on the lower surface of the cantilever plate 11. A second magnetic block 18 magnetically attracted to the clamping plate 12 is fixedly provided on the second limiting plate 17. When the first magnetic block 16 magnetically attracts the clamping plate 12, the lower surface of the clamping plate 12 is in contact with the end face of the slotted elbow.

[0024] Before processing begins, the first linear actuator 4 is activated to lift the clamping plate 3 upwards. Then, the center of the inner arc segment of the seam elbow is manually aligned with the lower surface of the clamping plate 3. Next, the left-side clamping plate 12 is manually flipped, allowing it to be attracted by the corresponding second magnet 18. During this process, the left-side rubber plug 13 expands into contact with the left end of the seam elbow. Then, the right-side clamping plate 12 is manually flipped, allowing it to be attracted by the corresponding second magnet 18. During this process, the right-side rubber plug 13 expands into contact with the right end of the seam elbow. Due to the symmetrical arrangement of the left and right clamping plates 12, the seam elbow can be centered below the clamping plate 3. Next, the first linear actuator 4 is activated to push the clamping plate 3 downwards, causing the clamping seat 2 and the clamping plate 3 to jointly clamp the seam elbow. Finally, the clamping plate 12 is manually flipped, allowing it to be attracted by the corresponding first magnet 16, exposing the end of the seam elbow.

[0025] When processing begins, the second linear actuator 7 and the beveling machine 6 are activated, causing the beveling tool of the beveling machine 6 to feed towards the end of the seamed bend, thus achieving beveling.

[0026] In the above embodiment, the front and rear side walls of the hollow base 1 are provided with operation holes 10 to accommodate the slotted elbow. The operation holes 10 are arched, and the slotted elbow can be easily installed and removed on the clamping plate 3 through the operation holes 10.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
