Description

Technical Field

[0001] The utility model relates to the technical field of bellows, in particular to a strength detection device for producing stainless steel bellows. Background Art

[0002] Metal bellows are pipes with a regular wave-like appearance. Commonly used metal bellows include carbon steel, stainless steel, steel with plastic lining, and aluminum. They are primarily used for connecting pipes to pipes or equipment where a very small bending radius is required, non-concentric axial transmission, irregular turns and expansions, or to absorb thermal deformation of pipes, or where fixed elbows are inconvenient to install.

[0003] After the metal bellows are produced, they need to be tested for strength. The operator takes the bellows sample and uses a manual stretching device to stretch the bellows to observe whether cracks and damage will appear in the stretched state. Manual stretching has the problem of low precision and the test results cannot be recorded with data, and it is impossible to accurately reach the limit value and observe the working conditions of the bellows under the limit state.

Directional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are intended solely to refer to the directions in the accompanying drawings. Therefore, these directional terms are intended to illustrate and facilitate understanding of the present invention and are not intended to limit the present invention.

[0016] like Figure 1-4The strength testing device for stainless steel corrugated pipe production shown in the figure includes a base 1 and a fixed assembly mounted on the base 1. The fixed assembly includes a fixed block 3, a splint 5, and a rubber strip 4. The fixed block 3 is fixedly mounted on the base 1. Two splints 5 are provided. The two splints 5 are slidably mounted on the fixed block 3. A chimeric block 10 is provided between the two splints 5. The chimeric block 10 is fixedly mounted on the fixed block 3. A rubber strip 4 is fixedly mounted above the chimeric block 10. The rubber strip 4 is vertically mounted on the chimeric block 10. A sleeve 6 and a rotating ring 7 are provided on the top of the rubber strip 4. A fixed plate 2 is fixedly mounted on one side of the base 1. The sleeve 6 is movably mounted on the fixed plate 2.

[0017] A threaded tube 13 is fixedly mounted at the bottom of the sleeve 6, and the rotating ring 7 is rotatably mounted on the outer wall of the threaded tube 13. The outer wall of the bottom of the threaded tube 13 is uniformly provided with multiple notches, which serve to increase the ductility of the outer wall of the bottom of the threaded tube 13. The inner wall of the rotating ring 7 is internally threaded, and the threaded tube 13 and the inner wall of the rotating ring 7 are connected by threads.

[0018] The top outer wall of the fixed block 3 is provided with a chute 8, within which a bidirectional screw 9 is mounted. The middle outer wall of the bidirectional screw 9 is connected via a bearing. Two clamping plates 5 are threadedly connected to the two sides of the bidirectional screw 9, which is driven by an external motor. A sleeve 6 is sleeved onto the outer wall of the rubber strip 4. A cylinder 11 is fixedly mounted on the side of the fixed plate 2 away from the rubber strip 4. The output end of the cylinder 11 faces the top of the rubber strip 4. A connecting plate 12 is fixedly mounted on the output end of the cylinder 11. The outer wall of the fixed plate 2 is provided with a lifting slot, which passes through the lifting slot and is fixedly connected to the outer wall of the sleeve 6.

[0019] Embodiment: The operator sets the metal bellows test sample that needs to be tested for strength on the outer wall of the rubber strip 4. In the initial state, the two plywoods 5 on the fixed block 3 are in the open state, and the sleeve 6 is located above the top of the rubber strip 4. The operator has enough space to set the bellows on the outside of the rubber strip 4 and set the bottom end of the bellows on the outside of the interlocking block 10. The upper outer wall of the interlocking block 10 is sloped, and the sloped outer wall can help the bottom end of the bellows to be more smoothly set on the outer wall of the interlocking block 10. Then the outer wall motor starts, driving the bidirectional screw 9 to rotate, so that the two plywoods 5 move toward the middle interlocking block 10. A slider is fixedly installed on the bottom outer wall of the plywood 5. The slider is adapted to the shape of the slide groove 8. The outer wall of the slider is provided with a threaded hole, which is adapted to the external thread of the bidirectional screw 9. The two plywoods 5 clamp the bottom of the bellows.

[0020] The cylinder 11 drives the sleeve 6 to descend, and it descends a corresponding distance according to the length of the bellows, so that the top end of the bellows is sleeved on the outside of the threaded tube 13. The operator rotates the rotating ring 7 on the outside of the threaded tube 13 so that the rotating ring 7 and the threaded tube 13 are threadedly engaged, and the top of the bellows can be clamped. The notch on the outer wall of the bottom of the threaded tube 13 can increase the ductility of the threaded tube 13, so that when the bellows is clamped, the bottom of the threaded tube 13 can be slightly deformed to adapt to the bellows being clamped in the middle. At this time, the bellows has been fixed, and the cylinder 11 can be operated to extend the output end and drive the sleeve 6 to rise through the connecting plate 12. The connecting plate 12 rises and falls inside the lifting groove of the fixed plate 2, and the sleeve 6 drives the bottom bellows to rise, stretching the bellows body. The operator observes the outer wall of the bellows to see whether the outer wall of the bellows will be damaged when the pulling force reaches the limit value.

[0022] The above-described embodiments merely represent several implementation methods of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the concept of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
