Description

Technical Field

[0001] The present application relates to the technical field of metal bellows end surface closing, and in particular to a clamp and a folding device for metal bellows end surface closing. Background Art

[0002] At present, metal bellows is a kind of pipe with regular wave-like appearance. Commonly used metal bellows are carbon steel, stainless steel, steel lined with plastic, aluminum, etc. It is mainly used for non-concentric axial transmission with a very small bending radius, or irregular turning, expansion, or absorbing thermal deformation of pipes, or for connecting pipes to pipes or pipes to equipment in occasions where it is not convenient to install with fixed elbows.

[0003] In order to ensure safe use, the pipe mouth of the metal bellows needs to be folded. There are many different types of folding equipment in the prior art, but the bellows must be clamped and fixed before folding (clamping is required for both the pipe body and the port). The existing clamp has a relatively single function and can only limit and fix one end at a time. When processing the other end, it needs to be clamped again, which is cumbersome to operate and has low production efficiency. Utility Model Content

[0004] The purpose of the present application is to provide a clamp and a folding device for closing the end face of a metal bellows that is easy to clamp, so as to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the present application provides a clamp and folding device for closing the end face of a metal bellows, which adopts the following technical solution.

[0006] On the one hand, the present application provides a clamp for closing the end face of a metal bellows, which adopts the following technical solution:

[0007] A clamp for closing the end face of a metal bellows comprises a left clamp and a right clamp, each of which comprises an upper clamp block, a lower clamp block and a connecting pipe, a connecting pipe being symmetrically connected between the upper clamp block and the lower clamp block, surfaces of the upper clamp block and the lower clamp block are provided with a clearance groove for clamping the bellows, and the upper clamp blocks on both sides and the lower clamp blocks on both sides are interlocked and fixed to each other.

[0008] Preferably, in order to facilitate disassembly and assembly, the side walls of the upper clamping block and the lower clamping block in the left clamping member are provided with slots, and the side walls of the upper clamping block and the lower clamping block in the right clamping member are provided with clamping strips at positions corresponding to the slots.

[0009] Preferably, in order to achieve a better fixing effect of the left clamping member and the right clamping member, a magnet block is fixed to the end of the clamping strip to facilitate overall movement.

[0010] Preferably, both ends of the connecting pipe penetrate through the wall thickness of the upper clamping block and the lower clamping block respectively, and both ends of the connecting pipe have adjustment grooves, and the upper clamping block and the lower clamping block are movably installed in the adjustment grooves.

[0011] By adopting the above technical solution, by providing an adjustment groove, the upper clamping block and the lower clamping block can move in the adjustment groove, which is convenient for the staff to quickly and easily clamp the metal bellows. When folding, when the upper clamping block or the lower clamping block is on the upper side, it will fit on the corrugated section at the upper end of the metal bellows under the action of its own gravity, thereby not affecting the folding.

[0012] On the other hand, the present application also provides a folding device using the above-mentioned metal bellows end surface closing clamp:

[0013] A folding device comprises a frame, a rotating table and a folding mechanism are installed on the frame, an inner support mechanism is fixed on the rotating table, a positioning rod is fixed on the rotating table, and the connecting pipe is matched and sleeved on the positioning rod.

[0014] In summary, the present application includes at least one of the following beneficial technical effects: the clamp for closing the end face of the metal bellows has a simple structure and is easy to clamp. By arranging the left clamp and the right clamp in a detachable and fixed manner, when clamping, it is only necessary to connect the left clamp and the right clamp on both sides and clamp them on the bellows, and the disassembly and assembly are also relatively simple; when folding the ends of the bellows with the folding device, there is no need to re-clamp the bellows, and it is only necessary to turn the direction of the clamp, which greatly improves the production efficiency.

DETAILED DESCRIPTION

[0019] The following is combined with Figure 1-3 This application is described in further detail.

[0020] The present application embodiment discloses a clamp for closing the end face of a metal bellows, referring to Figure 1-2 , including a left clamping member 1 and a right clamping member 2, both of which include an upper clamping block 3, a lower clamping block 4 and a connecting pipe 5, and a connecting pipe 5 is symmetrically connected between the upper clamping block 3 and the lower clamping block 4. The surfaces of the upper clamping block 3 and the lower clamping block 4 are provided with a makeshift groove 31 for clamping the corrugated pipe, and the upper clamping blocks 3 on both sides and the lower clamping blocks 4 on both sides are embedded and fixed to each other. The side walls of the upper clamping block 3 and the lower clamping block 4 in the left clamping member 1 are provided with a clamping groove 11, and the side walls of the upper clamping block 3 and the lower clamping block 4 in the right clamping member 2 are provided with a clamping strip 21 at the position corresponding to the clamping groove 11, and a magnet block 211 is fixed to the end of the clamping strip 21.

[0021] Reference Figure 1 and Figure 2 Both ends of the connecting pipe 5 penetrate the wall thickness of the upper clamping block 3 and the lower clamping block 4 respectively, and both ends of the connecting pipe 5 have adjustment grooves 51, and the upper clamping block 3 and the lower clamping block 4 are movably installed in the adjustment grooves 51.

[0022] By providing the adjustment groove 51, the upper clamping block 3 and the lower clamping block 4 can move in the adjustment groove 51, so that the staff can quickly and easily clamp the metal bellows. When folding, when the upper clamping block 3 or the lower clamping block 4 is on the upper side, it will fit on the corrugated section at the upper end of the metal bellows under the action of its own gravity, thereby not affecting the folding.

[0023] The implementation principle of a clamp for closing the end surface of a metal bellows in the embodiment of the present application is as follows:

[0024] When clamping, it is only necessary to dock the left clamping piece 1 and the right clamping piece 2 on both sides and clamp them on the corrugated tube. By inserting the clamping strip 21 into the clamping slot 11, the left clamping piece 1, the right clamping piece 2 and the corrugated tube can be combined into a whole so as to be placed on the folding device later.

[0025] The present application also discloses a folding device using the above-mentioned metal bellows end surface closing fixture, referring to Figure 3 , including a frame 6, a rotating table 7 and a folding mechanism 8 are installed on the frame 6, an inner support mechanism 9 is fixed on the rotating table 7, a positioning rod 71 is fixed on the rotating table 7, and a connecting pipe 5 is matched and sleeved on the positioning rod 71.

[0026] During operation, the entire clamp with the corrugated tube already clamped is put on the positioning rod 71 of the rotating table 7 through the connecting tube 5. After that, the internal support mechanism 9 on the rotating table 7 is opened to squeeze the corrugated tube onto the yield groove 31 on the surface of the upper clamping block 3 and the lower clamping block 4. After that, the rotating table 7 rotates, and the folding mechanism 8 presses on the corrugated tube to perform folding. After the folding of one end is completed, it is only necessary to turn the clamp over and put it on the positioning rod 71, and repeat the above folding work. After the folding is completed, after removing the entire clamp from the positioning rod 71, the staff separates the left clamp 1 and the right clamp 2 in a straight line, and the corrugated tube can be easily removed.

[0027] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, principle and application direction of the present application should be included in the protection scope of the present application.
