Embodiment 1
[0021] Embodiment 1: structure such as figure 1 , figure 2 As shown, a mooring chain transom rolling device includes a rolling die 2, an oil cylinder 3 and a body 5, the oil cylinder 3 is installed inside the body 5, and the calendering die 2 is connected to the piston rod of the oil cylinder 3.
[0022] Utilize above-mentioned mooring chain crosspiece calendering device to the technology of mooring chain crosspiece calendering as follows:
[0023] (1) Through the transmission mechanism, each link of the mooring chain passes through the calendering device in turn, and the positioning cylinders on both sides automatically position the links that need to be calendered;
[0024] (2) The crosspiece of the mooring chain is rolled by the calendering molds on both sides driven by the cylinder piston, so that the rolled crosspiece is extended and expanded longitudinally, so as to eliminate the gap between the two ends of the crosspiece and the ring body.
[0025] In the above-menti...
Embodiment 2
[0028] Embodiment 2: The mooring chain crosspiece calendering device and the main rolling process are the same as in Example 1, the difference is that in the mooring chain crosspiece calendering process, the pressure of the hydraulic system calendering is adjusted according to different product specifications, and the general control At 10-18MPA, such as R4∮76 mooring chain, when the crosspiece is rolled, the hydraulic system pressure is usually 10MPA.
Embodiment 3
[0029] Embodiment 3: The mooring chain crosspiece calendering device and the main rolling process are the same as in Example 1, the difference is that in the mooring chain crosspiece calendering process, the pressure of the hydraulic system calendering is adjusted according to different product specifications, and the general control At 10-18MPA, such as R4∮111 mooring chain, when the crosspiece is rolled, the hydraulic system pressure is usually 18MPA.

Abstract
A mooring chain transom rolling device and a rolling process thereof belong to the technical field of mooring chain manufacturing. The mooring chain transom rolling device comprises rolling dies, an oil cylinder and a machine body, wherein, the oil cylinder is arranged in the machine body and the rolling die is connected with a piston rod of the oil cylinder. The mooring chain transom rolling process by adopting the mooring chain transom rolling device comprises the following steps: (1) chain rings of the mooring chain sequentially pass the rolling device by a transmission mechanism; the chain rings needing transom rolling are automatically positioned by a positioning oil cylinder at the two sides; (2) the rolling dies at the two sides are driven by an cylinder piston to roll the transom of the mooring chain to cause the rolled transom to vertically generate distension, thus eliminating the clearance between the two ends of the transom and the ring bodies. The mooring chain transom rolling device has the advantages of reasonable design, simple structure, simple manufacturing, convenient use and practicable process, and the rolling process has the advantages of saving raw materials, improving work efficiency, causing the mooring chain transom and the chain rings to be tightly linked, and solving the loose transom problem after mooring chain heat treatment.
Description
technical field [0001] The invention relates to a mooring chain crosspiece calendering device and a calendering process, belonging to the technical field of mooring chain manufacturing. technical background [0002] In our country, a large number of mooring chains are produced every year. Due to the relatively weak manufacturing base, in the production process, the problem of loosening of the crosspieces after heat treatment of the mooring chains will inevitably occur. In the actual use process, due to the looseness of these crosspieces Existence will often result in the scrapping of the entire article. If the defective single ring in the whole mooring chain is replaced, the problem that the whole mooring chain is scrapped can be effectively solved. This is also a technical difficulty common to mooring chain manufacturers all over the world. So far, no domestic manufacturer has a more reasonable process to solve this problem. Contents of the invention [0003] Aiming at...
