Description

Technical Field

[0001] The utility model relates to the field of corrugated pipe tooling, and more specifically, to a corrugated pipe stretching tooling. Background Art

[0002] Bellows refers to a tubular elastic sensitive element formed by connecting foldable corrugated sheets along the folding and expansion direction. Bellows are widely used in construction, factory production, and instrumentation. The produced bellows need to be tested for fatigue strength using tensile tooling to ensure the quality of the finished product.

[0003] During the operation of the stretching tool, it is necessary to manually place the two ends of the tube body in the locking components in sequence, and use the displacement of the locking components to stretch the two sides of the tube body. The process of manually placing the two sides of the tube body in sequence is not only cumbersome, but also inconvenient to adapt to tubes of different lengths for simultaneous testing. Therefore, it is necessary to design a corrugated tube stretching tool with simple operating steps to solve the above problems. Utility Model Content

[0004] 1. Technical issues to be solved

[0005] In view of the problems existing in the prior art, the purpose of the utility model is to provide a bellows stretching tool, which can utilize an electric guide rail to drive the right slider to move the right arc circle to the right, so as to stretch the bellows body. It can also perform stretching inspection operations on bellows bodies of different lengths at the same time, which saves time, labor and efficiency.

[0006] Technical Solution

[0007] To solve the above problems, the utility model adopts the following technical solutions.

[0008] A corrugated pipe stretching tool comprises a workbench, wherein the upper end of the workbench is fixedly connected to a plurality of left-side upright blocks, the upper end of the workbench is fixedly connected to a plurality of electric guide rails, the output end of the electric guide rail is fixedly connected to a right-side slider, the upper end of the left-side upright block is fixedly connected to a left-side clamping ring, the upper end of the right-side slider is fixedly connected to a right-side arc circle, the right-side arc circle comprises a bottom arc circle, the front and rear ends of the bottom arc circle are fixedly connected to an electric rotating shaft, the output end of the electric rotating shaft is fixedly connected to an open arc piece, the left and right inner walls of the bottom arc circle are symmetrically provided with side slots, the lower inner walls of the side slots are fixedly connected to springs, and a roller member is fixedly connected between the two springs.

[0009] Furthermore, the upper ends of the right arc ring and the left clamping ring are clamped with the bellows body, and the roller part is in contact with the bellows body.

[0010] Furthermore, the two opening arc pieces are respectively located on the left and right sides of the bellows body, and the opening arc pieces match the bellows body.

[0011] Furthermore, one end of the two opened arc pieces close to each other is fixedly connected with an abutment strip, and the upper end of the bottom arc circle is symmetrically provided with channels.

[0012] Furthermore, the abutting strip runs through the inside and outside of the channel, and the abutting strip is in contact with the roller member.

[0013] Furthermore, a control panel is fixedly connected to the front end of the workbench.

[0014] Furthermore, the control panel is electrically connected to the plurality of electric guide rails and the electric rotating shaft through wires. Beneficial Effects

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] (1) In this scheme, multiple bellows bodies are sequentially clamped in the left clamping ring and the right arc ring on the workbench, and the right arc ring is moved to the right by the electric guide rail to stretch the bellows body. The bellows bodies of different lengths can be stretched and tested at the same time.

[0017] (2) When the right arc circle moves to the right, a roller member in contact with the bellows body can be set on the lower inner wall of the right arc circle. When the right arc circle moves to the right, the roller member can reduce the hard friction between the open arc piece and the outer wall of the bellows body, making the sliding path of the open arc piece outside the bellows body smoother, thereby avoiding the risk of wear on the outer wall of the electric shaft.

[0018] (3) At the same time, when the electric shaft drives the arc piece to open and retract, the abutting strip close to the bottom arc circle is pressed down along the channel, pressing down the positions on both sides of the roller part, so that when the right arc circle fits the bellows body, the roller part is not easy to produce hard contact with the outer wall of the bellows body, further ensuring the integrity of the outer wall of the bellows body, and the use method is flexible.
