Description

Technical Field

[0001] The utility model relates to the technical field of pipe end forming, in particular to a pipe end extrusion forming device. Background Art

[0002] With the development and application of the non-welded pipeline technology in the hydraulic industry, it has become possible to achieve non-pipeline welding installation at more production sites, shorten the installation cycle, and avoid secondary pollution. Therefore, from the perspectives of improving the performance stability and reliability of the hydraulic system, shortening the product manufacturing cycle, reducing the product manufacturing cost, significantly reducing the failure rate of the hydraulic system, and saving energy and protecting the environment, the research on the non-welded pipeline technology is particularly important.

[0003] In a hydraulic system, hydraulic pipelines mainly connect various hydraulic components and devices through metal hard pipes and high-pressure resistant hoses to transmit energy. The basic requirements of the pipeline system are to have sufficient strength to withstand the higher impact pressure and working pressure of the system, and the connections between the pipeline and each hydraulic component and device should be sealed reliably, without leakage, and must not be loose.

[0004] The traditional ferrule swaging connection method has the problems of high operation cost, easy oil leakage of the swaged ferrule, and low efficiency. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the utility model provides a pipe end extrusion forming device, which overcomes the deficiencies of the prior art and effectively solves the problems of the traditional ferrule swaging connection method in the prior art, such as high operation cost, easy oil leakage of the swaged ferrule, and low efficiency.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] The pipe end extrusion forming device includes a forming oil cylinder. A cooling mechanism is arranged on one side of the forming oil cylinder, and a servo drive mechanism is arranged below the forming oil cylinder. A cooling circulation cylinder is arranged on one side of the servo drive mechanism, and an oil tank is connected to one side of the cooling circulation cylinder. One end of the oil tank is connected to a forming controller. The cooling mechanism includes a cooling box, dust-proof covers connected to both ends of the outer wall of one side of the cooling box, a cooling fan arranged on one side of the dust-proof cover and inside the cooling box, a liquid inlet pipe inserted and fixed at one end of the top of the cooling box, and a liquid outlet pipe inserted and fixed at the other end of the top of the cooling box.

[0008] Preferably, a curved condensing pipe is arranged inside the cooling box, and both ends of the condensing pipe are inserted and communicated with the liquid inlet pipe and the liquid outlet pipe respectively.

[0009] The curved condensing pipe prolongs the passing time and path of the oil in the cooling box, thereby improving the cooling efficiency of the oil in the condensing pipe.

[0010] Preferably, one end of the liquid inlet pipe is inserted and fixed with a first oil delivery pipe, and the other end of the first oil delivery pipe is inserted and fixed with the cooling circulation cylinder.

[0011] The cooling circulation cylinder and the cooling mechanism are connected through the first oil delivery pipe.

[0012] Preferably, the bottom of the cooling circulation cylinder is inserted and fixed with a second oil delivery pipe, and the second oil delivery pipe is inserted and fixed with the bottom of the fuel tank.

[0013] The cooling circulation cylinder and the fuel tank are connected through the second oil delivery pipe.

[0014] Preferably, a spiral delivery pipe is arranged in the fuel tank, the bottom end of the spiral delivery pipe is inserted and fixed with the second oil delivery pipe, and the top end of the spiral delivery pipe is inserted and fixed with a third oil delivery pipe.

[0015] By circulating the oil in the spiral delivery pipe, the low-temperature oil cools the oil in the fuel tank, ensuring a low-temperature environment for the oil in the fuel tank.

[0016] Preferably, an oil level indicator is inserted into the top of the fuel tank, and a ventilation cap is inserted into a corner of the top of the fuel tank.

[0017] The oil level in the fuel tank is monitored and displayed through the oil level indicator.

[0018] Preferably, a temperature sensor is installed at the bottom of the fuel tank, and the forming controller and the fuel tank are connected and fixed through a connecting pipe.

[0019] The oil temperature in the fuel tank is monitored through the temperature sensor, and when the oil temperature is relatively high, the cooling mechanism is started to reduce the oil temperature in the fuel tank.

[0020] The beneficial effects of the present utility model are as follows:

[0021] Compared with the traditional welded pipeline installation or the pre-tightening installation with a manual wrench and ferrule, the automatic forming of the new extrusion forming equipment greatly shortens the installation period. There is no need for pickling, flaw detection, and electric welding, and the installation can be completed at one time, which is convenient for later maintenance and replacement, saves installation time, realizes large-scale production in the workshop, reduces labor costs and pipeline installation costs, and saves the operating costs of mechanical automatic pipeline installation.

[0022] Through the implementation and promotion of this project, automatic welding-free pipeline installation is realized, which improves the labor intensity of workers, reduces labor costs, solves the problems of low efficiency and high failure rate in manual operation, and avoids environmental pollution caused by hydraulic medium leakage.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0029] Embodiment: Refer to Figures 1-4 , the tube end extrusion forming device includes a forming oil cylinder 1, a cooling mechanism 2 is arranged on one side of the forming oil cylinder 1, a servo drive mechanism 3 is arranged below the forming oil cylinder 1, a cooling circulation cylinder 4 is arranged on one side of the servo drive mechanism 3, a fuel tank 5 is connected to one side of the cooling circulation cylinder 4, a forming controller 6 is connected to one end of the fuel tank 5, the cooling mechanism 2 includes a cooling box 10, dust-proof covers 11 connected to both ends of the outer wall of one side of the cooling box 10, a cooling fan 12 arranged on one side of the dust-proof cover 11 and located inside the cooling box 10, a liquid inlet pipe 13 inserted and fixed at one end of the top of the cooling box 10, and a liquid outlet pipe 14 inserted and fixed at the other end of the top of the cooling box 10;

[0030] Inside the cooling box 10, there is a curved condensing pipe. The two ends of the condensing pipe are respectively inserted and communicated with the liquid inlet pipe 13 and the liquid outlet pipe 14. By means of the curved condensing pipe, the passing time and path of the oil liquid in the cooling box 10 are extended, thereby improving the cooling efficiency of the oil liquid in the condensing pipe. One end of the liquid inlet pipe 13 is inserted and fixed with a first oil delivery pipe 7. The other end of the first oil delivery pipe 7 is inserted and fixed with the cooling circulation cylinder 4. The cooling circulation cylinder 4 and the cooling mechanism 2 are communicated through the first oil delivery pipe 7. The bottom of the cooling circulation cylinder 4 is inserted and fixed with a second oil delivery pipe 8. The second oil delivery pipe 8 is inserted and fixed with the bottom of the fuel tank 5. The cooling circulation cylinder 4 and the fuel tank 5 are communicated through the second oil delivery pipe 8;

[0031] Inside the fuel tank 5, there is a spiral conveying pipe. The bottom end of the spiral conveying pipe is inserted and fixed with the second oil delivery pipe 8. The top end of the spiral conveying pipe is inserted and fixed with a third oil delivery pipe 9. By means of the oil liquid flowing in the spiral conveying pipe, the low-temperature oil liquid cools the oil in the fuel tank 5, ensuring a low-temperature environment for the oil in the fuel tank 5. An oil level indicator 15 is inserted into the top of the fuel tank 5. A ventilation cap 16 is inserted into a corner at the top of the fuel tank 5.
