Description

Technical Field

[0001] This invention belongs to the field of hose manufacturing technology, specifically relating to a continuous processing method and production line for composite oil-resistant hoses. Background Technology

[0002] Composite oil-resistant hoses are high-performance pipes specifically designed for transporting oily media. They achieve comprehensive performance such as oil resistance, pressure resistance, wear resistance, and aging resistance through a multi-layer composite structure. Summary of the Invention

[0003] Existing continuous processing methods for composite oil-resistant rubber hoses, when used for the automated and continuous production of long-length, multi-layer composite oil-resistant rubber hoses, suffer from problems in traditional segmented processing, such as difficulties in inter-process transfer, inconvenient handling, and low production efficiency due to the excessive length of the hose. The purpose of this invention is to provide a continuous processing method and production line for composite oil-resistant rubber hoses, aiming to solve the aforementioned problems.

[0004] To achieve the above objectives, the present invention provides a continuous processing method for composite oil-resistant rubber hoses, comprising the following steps: 1) Tube blank introduction: The tube blank containing the inner rubber layer or the tube blank with the hard core is fed into the production line at a uniform speed through the traction device. 2) First layer of braiding: The tube blank first enters the first wire braiding machine, and the equipment automatically completes the processing of the first wire braiding layer on the outside of the tube blank according to the set process; 3) Skeleton processing: The semi-finished product after the first layer of weaving is directly pulled into the closely connected steel wire skeleton processing machine without manual handling; at this station, the equipment automatically spirally winds the skeleton steel wires on the outside of the tube body at the set pitch to form a steel wire skeleton layer.

[0005] 4) Second layer of braiding: After the skeleton layer is processed, the tube continues forward and directly enters the second wire braiding machine connected at the rear to complete the processing of the second wire braiding layer on the outside of the skeleton layer; 5) Finished product output: After processing by the above-mentioned continuously connected equipment, a composite oil-resistant hose with an "inner braid - middle skeleton - outer braid" structure is directly generated.

[0006] A composite oil-resistant rubber hose production line includes a first wire braiding machine for braiding a first layer of wire mesh onto the outside of a pipe blank coated with an inner rubber layer. A wire skeleton processing machine is directly connected to the rear of the first wire braiding machine for spirally winding a wire skeleton layer onto the first layer of wire mesh. A second wire braiding machine is directly connected to the rear of the wire skeleton processing machine for braiding a second layer of wire mesh onto the wire skeleton layer.

[0007] Reducing labor intensity and circulation costs: since rubber hoses are usually long in length, it is extremely inconvenient and laborious to frequently move products between different equipment in traditional processing. The present invention eliminates the semi-finished product handling between processes and reduces the labor intensity of workers.

[0008] Improving product quality and stability: continuous processing avoids possible contamination, deformation or interlayer looseness of semi-finished products during handling and stagnation, which helps ensure the consistency of tension between the steel wire braided layer and the framework layer, thereby improving the overall quality of the hose body.

[0009] Compared with the prior art, the beneficial effects of the present invention are: the present invention integrates three originally independent processes into a single production line, realizes one-time continuous forming of rubber hoses, greatly shortens the production cycle and improves production efficiency. DETAILED EMBODIMENTS

[0010] The present invention provides the following technical solution: a continuous processing method for composite oil-resistant rubber hoses, comprising the following steps: 1) Tube blank introduction: feed the tube blank containing inner layer rubber or the tube blank with a hard core into the production line at a constant speed through a traction device; 2) First layer braiding: the tube blank first enters a first steel wire braiding machine, and the equipment automatically completes processing of the first steel wire braided layer on the outer side of the tube blank according to a set process; 3) Framework processing: the semi-finished product after completing the first layer braiding does not need manual handling, and is directly pulled into a tightly connected steel wire framework processing machine at the rear; at this station, the equipment automatically spirally winds framework steel wires on the outer side of the hose body according to a set pitch to form a steel wire framework layer.

[0011] 4) Second layer braiding: the hose body after framework layer processing continues to move forward, and directly enters a second steel wire braiding machine connected at the rear to complete processing of the second steel wire braided layer on the outer side of the framework layer; 5) Finished product output: after processing by the above continuously connected equipment in series, a finished composite oil-resistant rubber hose with an "inner braiding-middle framework-outer braiding" structure is directly generated.

[0012] A production line for composite oil-resistant rubber hoses, comprising a first steel wire braiding machine: configured for braiding a first layer of steel wire mesh outside a tube blank covered with an inner rubber layer. A steel wire framework processing machine: directly connected to the rear of the first steel wire braiding machine, configured for spirally winding a steel wire framework layer on the first layer of steel wire mesh. A second steel wire braiding machine: directly connected to the rear of the steel wire framework processing machine, configured for braiding a second layer of steel wire mesh on the steel wire framework layer.

[0013] Reducing labor intensity and circulation costs: since rubber hoses are usually long in length, it is extremely inconvenient and laborious to frequently move products between different equipment in traditional processing. The present invention eliminates the semi-finished product handling between processes and reduces the labor intensity of workers.

[0014] Improve product quality and stability: Continuous processing avoids contamination, deformation or loosening between layers that may occur during the handling and stagnation of semi-finished products, which helps to ensure the consistency of tension between the steel wire braided layer and the skeleton layer, thereby improving the overall quality of the tube.

[0015] Compared with the prior art, the beneficial effects of the present invention are: the present invention improves production efficiency: it integrates the originally independent three processes (first braiding, winding skeleton, second braiding) into a production line, realizes one-time continuous molding of rubber hoses, and greatly shortens the production cycle.

Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
