Detailed Description
The present invention will be described in further detail with reference to the following examples in order to make the objects, technical solutions and advantages of the present invention more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
In order to solve the problems of large space of a required production line and inconvenient arrangement of used equipment in the traditional wire and cable production process, the invention particularly provides a cooling and drying method for automobile cable production, which can greatly reduce the space required by the cable drying process and improve the utilization rate of a production workshop. For further explanation of the structure of the present invention, the detailed description is as follows in connection with the accompanying drawings:
referring to fig. 1, a cooling and drying method for producing an automobile cable includes the following steps:
the first step: the cable is wound to form a winding line section, and the cable forms a plurality of upper layer wire harnesses which are transversely arranged and a plurality of lower layer wire harnesses which are transversely arranged on the winding line section. In this embodiment, the cable winding is achieved by two winding wheels 1, between which the cable 2 forms a winding track. Namely, two winding wheels which can rotate around the axes of the two winding wheels are arranged, and the axes of the two winding wheels are horizontal and parallel. The winding line section represents a straight line section between two winding wheels in the process of winding the cable through the winding wheels.
The extruded or vulcanized automobile cable is led in from one side of the two winding wheels, is repeatedly wound between the two winding wheels for a plurality of times, and then extends out from one side of the other winding wheel, and according to common knowledge, the wire harness forms two layers of wire harnesses which are distributed up and down and are opposite in moving direction between the two winding wheels under the state that the wire harnesses are wound in a range between the two winding wheels. The axes of the two wheels are typically parallel, but they are not the same shaft. The wheel has a wire slot for winding the wire, and the other wheel is used for fixing the other end of the wire or as an outlet for the wire. Thus, by rotating the wheel, the wire can be wound back and forth between the two wheels. To achieve the entrance of the cable from one side of the wheel, the cable is wound repeatedly and sequentially and then exits from the other side of the wheel, and the wire grooves of the two wheels can be designed into complementary V-shapes or U-shapes in angle. In particular, the wire grooves of one wheel may be designed in a V-shape, the wire grooves of the other wheel in an inverted V-shape, or the wire grooves of one wheel in a U-shape, the wire grooves of the other wheel in an inverted U-shape. In this way, the cable can shuttle back and forth between the two wheels when being wound, and an orderly winding path is maintained, and the design also belongs to the conventional design in the mechanical field.
Other parameter designs for winding wheels:
the number and arrangement of the wire slots: the number and arrangement of the wire grooves on the wheel should be reasonable to ensure that the cable maintains a uniform tension and a stable winding path when being wound. The number and arrangement of the trunking should be determined according to the characteristics of the cable, the application requirements and the size of the wheel.
Size and spacing of the wheels: the size and spacing of the wheels also affects the winding effect of the cable. Larger wheel diameters and larger wheel spacings may result in uneven tension or unstable winding paths of the cable while winding, while smaller wheel diameters and smaller wheel spacings may limit the winding capacity of the cable. Therefore, the size and spacing of the wheels should be reasonably selected to meet the winding requirements of the cable.
Winding speed and tension control: the cable winding speed and tension control of the winding wheel also play a key role in orderly winding the cable back and forth. Too high or too low winding speed and tension may cause unstable winding of the cable or cross-over. Therefore, the winding speed and the tension should be reasonably controlled according to the characteristics and the application requirements of the cable so as to ensure the orderly winding of the cable.
These conditions may vary depending on the particular application and the characteristics of the automotive cable, and therefore, in designing the winding wheel, reasonable design and adjustment should be made according to the actual situation of the automotive cable applied to ensure that the cable can be wound back and forth on the wheel in order.
And a second step of: and (3) cooling the wire harness positioned at the upstream of the wire in the winding wire section by water, and drying the wire harness positioned at the downstream of the wire in the winding wire section by blow. It is emphasized that the cable must be cooled by water before blow-drying in the direction along which the cable is routed. In this embodiment, the upper layer wire harness and the lower layer wire harness at the downstream end of the wire are dried in the winding wire section, and the upper layer wire harness and the lower layer wire harness at the downstream end of the wire are two straight single bundles located at the upper layer and the lower layer before the cable stretches out of the winding wire section.
Referring to fig. 2 and 3, for water cooling, in this embodiment, a cooling tank 3 is disposed near the lower side of the upper layer wire harness and the lower layer wire harness, a cooling liquid is disposed in the cooling tank, and the upper layer wire harness and the lower layer wire harness located upstream of the wire harness in the winding wire harness are immersed in and pass through the cooling liquid.
To blow dry, be close to upper wiring harness and lower floor's pencil setting and blow dry the subassembly, blow dry the subassembly and provide and blow dry gaseous to upper wiring harness and lower floor's pencil that are located the line low reaches in the winding line section of walking. The blow-drying assembly comprises a blow-drying groove 4 extending along the moving direction of the cable and a plurality of blow-drying parts 5 arranged along the moving direction of the cable of the automobile.

Further, the blow-drying assembly includes a blow-drying component that provides a heated drying gas.
The types of air drying parts that may be used include compressed air guns: the common gas blow-drying equipment sprays the high-pressure compressed air onto the surface of the cable to achieve the blow-drying effect. Common models are air flow spray guns, jet nozzles, and the like. High-pressure fan: the air flow generated by the high-pressure fan can be used for blowing the surface of the cable. Common models are centrifugal fans, axial fans and the like. A hot air gun: through producing hot air, evaporate the moisture on cable surface to realize the effect of weather. Common models are electric heat air guns, gas heat air guns and the like. In selecting the high pressure gas blow-down components, factors such as the production speed, drying effect, energy consumption, safety, equipment maintenance and the like of the cable should be considered, and relevant safety operation rules and standards should be followed.
In the embodiment, after the space design is optimized, the length of the line of the blow-drying assembly is greatly increased, the air source pressure of the blow-drying component can be selected to be 0.05-0.15 MPa, the blow-drying effect can be achieved, the phenomenon that the compressed air of the original blow-drying device is 0.4-0.6 MPa, a large amount of heat is taken away by the compressed air to be wasted is avoided, the noise generated when the compressed air is blown out is greatly reduced, and the heating electric energy is saved by 20-30%.

Among the row-shaped wire harnesses, one wire harness at the moving end of the automobile cable is located in the blow-drying groove, and other wire harnesses penetrate through the cooling groove. Further, blow-drying parts along the line of the blow-drying groove are four parts, wherein normal-temperature compressed air can be provided at the moving front end of the automobile cable, and hot drying compressed air can be provided at the rear end of the automobile cable. The added hot air blow-dries the component, so that the temperature and the dryness of the surface of the wire harness of the automobile cable can be improved, and the firmness of subsequent ink printing is ensured.
