Description

Technical Field

[0001] The invention relates to the technical field of cable sheath production, and in particular to a device for preparing corrosion-resistant and wear-resistant wire and cable sheath material and a preparation process thereof. Background Art

[0002] The cable sheath is the outermost layer of the cable. Its appearance is required to be smooth and round, with uniform gloss and no eccentricity. It has functions such as moisture-proof and electric shock-proof. The cable sheath can effectively protect the internal wires to reduce damage and extend the service life of the wires. When the cable sheath is produced, the materials are melted and mixed, and then the mixed materials are extruded and molded into a cable sheath through an extruder. The cable sheath that has just been extruded will have a higher temperature. In order to accelerate the hardening and molding of the cable sheath, it is necessary to evenly spray water on the outer surface of the formed cable sheath for rapid cooling.

[0003] At present, in actual production, the formed cable sheath is mostly cooled by uniformly spraying water. Due to the high cost of using pure water, the water used in this cooling method is mostly groundwater, which contains many trace elements. When the water directly contacts the outer surface of the cable sheath under high temperature, it will produce thermal expansion and contraction effects. At the same time, due to the impact of the water flow and the chemical reaction of the trace elements, the thermal expansion and contraction of the cable sheath will be uneven, resulting in tiny concave cracks on the outer surface of the cable sheath. Such cracks will accelerate the aging and cracking of the cable sheath during subsequent use. Summary of the invention

The preparation process for preparing a corrosion-resistant and wear-resistant wire and cable sheath material comprises the following steps:

[0016] Step S1: injecting the external molten material into the material cavity through the feed pipe. When working, the molten material in the material cavity can enter the molding cavity for pre-molding through the push component. When the push component is driven, the cooling device is driven to work, so that the pre-molded object just out of the molding cavity is quickly cooled and molded. When the push component moves, the sealing component can prevent the molten material in the material cavity from leaking, and the feed pipe is controlled to be on and off. When the push component runs to the bottom, it is positioned by the positioning component;

[0017] Step S2: When the cooling device is working, the two arc-shaped cooling plates are engaged with each other to form a confined space identical to the molding cavity, thereby rapidly cooling the preformed object when the preformed object is extruded from the molding cavity to the outside;

[0018] Step S3: When the positioning component is working, when the pushing component is about to discharge all the materials in the material cavity, the contact block is pushed outward by the fixing rod, thereby driving the positioning component to constrain the pushing component to prevent the pushing component from vibrating when the material reaches the bottom, causing water ripples to appear on the product;

[0019] Step S4: When the sealing component is working, the sliding sealing fit between the slide plate and the sliding port can prevent the material in the material cavity from overflowing from the sliding port to the outside when the pushing component is working, and the through hole is opposite to the feed pipe to control the on and off of the feed pipe;

[0020] Step S5: When the pushing component is working, the two arc-shaped cooling plates are squeezed by the constraint plate so that the two arc-shaped cooling plates can be relatively engaged, and at the same time, the annular sealing block is driven to slide downward inside the material cavity, so that the molten material inside the material cavity is squeezed into the molding cavity for pre-forming, and the positioning component can also be triggered to work.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can quickly cool the preformed articles coming out of the molding cavity by providing a cooling device. By providing a positioning component, when the material in the material cavity is about to be exhausted, the pushing component can be constrained to prevent the pushing component from vibrating when the material reaches the bottom, causing water ripples on the product. By providing a sealing component, the leakage of molten material in the material cavity can be prevented during the operation of the pushing component. By providing the pushing component, the cooling device, the positioning component and the sealing component can be driven to work synchronously.

[0023] 2. The present invention can quickly cool the preformed object coming out of the molding cavity by arranging a cooling device. When the cooling device is working, the two arc-shaped cooling plates are engaged with each other to form a confined space identical to the molding cavity, thereby quickly cooling the preformed object when the preformed object is extruded from the molding cavity to the outside.

[0024] 3. The present invention can seal the sliding port by setting a sealing component, and at the same time does not interfere with the movement of the slide plate. When the sealing component is working, the sliding sealing fit between the slide plate and the sliding port can prevent the material inside the material cavity from overflowing from the sliding port to the outside when the push component is working, and the through hole is opposite to the feed pipe, so the on and off of the feed pipe can be controlled;

[0025] 4. The present invention can position the pushing component through the positioning component. When the positioning component is working, when the pushing component is about to discharge the material inside the material cavity, the contact block is pushed outward through the fixing rod, thereby driving the positioning component to constrain and position the pushing component.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the implementation regulations described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] See also Figure 1-10 The present invention provides a technical solution: a device for preparing corrosion-resistant and wear-resistant wire and cable sheath material, comprising a fixed column 1, a material cavity 19 penetrating to the top is opened inside the fixed column 1, a molding cavity 18 penetrating to the bottom is opened inside the fixed column 1, a support column 26 is fixed to the inner bottom surface of the molding cavity 18, a pushing component is arranged on the outer surface of the fixed column 1, a cooling device is arranged at the bottom of the fixed column 1, a positioning component is arranged inside the fixed column 1, and a sealing component is arranged on the inner wall of the fixed column 1;

[0039] The inner bottom surface of the material cavity 19 is provided with a plurality of openings 27 which penetrate into the interior of the molding cavity 18 at equal intervals in the circumferential direction. Feed pipes 2 are fixed on both sides of the fixed column 1 near the top edge. The two feed pipes 2 penetrate into the interior of the material cavity 19 correspondingly. Connecting plates 32 are fixed between the inner walls of the material cavity 19 near the top edge. Pressure rods 33 are fixed at the bottom of the two connecting plates 32. A heating cavity 22 is provided inside the fixed column 1 on the inner side of the material cavity 19. A plurality of heating resistors 23 are fixed between the inner bottom surface and the top surface of the heating cavity 22 at equal intervals in the circumferential direction.

[0040] The effect achieved is that the external molten material is injected into the material cavity 19 through the feed pipe 2. When working, the molten material in the material cavity 19 can enter the molding cavity 18 for pre-molding through the pushing component. When the pushing component is driven, the cooling device will be driven to work, so that the pre-molded items just out of the molding cavity 18 can be quickly cooled and formed. When the pushing component moves, the sealing component can prevent the molten material in the material cavity 19 from leaking, and at the same time control the on and off of the feed pipe 2. When the pushing component runs to the bottom, it is positioned by the positioning component. A heating resistor 23 is arranged inside the heating cavity 22. The heating resistor 23 can generate heat to heat and keep the molten material in the material cavity 19 warm, so as to prevent the temperature difference from causing the molten material to condense inside the material cavity 19, resulting in poor fluidity.

[0041] like Figure 2 , Figure 3 and Figure 5 As shown, the sealing assembly includes a slide plate 14, and sliding openings 4 are provided on the outer surfaces of both sides of the fixed column 1, and the two sliding openings 4 are correspondingly extended to the interior of the material cavity 19, and guide grooves 21 are provided on the inner top and bottom surfaces of the two sliding openings 4. The guide groove 21 located on the inner top surface of the sliding opening 4 extends to the top of the fixed column 1, and the bottom of the guide groove 21 located on the inner bottom surface of the sliding opening 4 extends to the outer surface of the fixed column 1, the slide plate 14 is slidably connected between the inner walls of the sliding opening 4, and the top and bottom of the slide plate 14 are correspondingly extended to the interior of the guide groove 21, and the top of the slide plate 14 extends to the top of the fixed column 1, the guide groove 21 is connected to the feed pipe 2, and a through hole 20 is provided on one side of the slide plate 14, and the through hole 20 is relatively connected to the feed pipe 2.

[0042] The effect achieved is that the sliding sealing fit between the slide plate 14 and the sliding port 4 can prevent the material inside the material cavity 19 from overflowing from the sliding port 4 to the outside when the pushing component is working, and the through hole 20 is opposite to the feed pipe 2, so the on and off of the feed pipe 2 can be controlled. In the initial state of the entire device, the through hole 20 is opposite to the feed pipe 2. At this time, the external molten material can enter the material cavity 19 through the feed pipe 2. When the pushing component is working, it will drive the slide plate 14 to slide downward. At this time, the through hole 20 and the feed pipe 2 are misaligned with each other, so the feed pipe 2 can be cut off. At this time, the external molten material cannot enter the material cavity 19 through the feed pipe 2. By setting a sealing component, the sliding port 4 can be sealed without interfering with the movement of the slide plate 14 and controlling the on and off of material injection.

[0043] like Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 As shown, the pushing assembly includes a sliding ring 3, which is slidably connected between the outer surfaces of the fixed column 1, and sliding blocks 11 are fixed to the inner walls on both sides of the sliding ring 3. The two sliding blocks 11 are correspondingly slidably connected to the inside of the sliding port 4, and one side of the two sliding blocks 11 is correspondingly fixed on the slide plate 14. A plurality of constraint plates 5 are fixed to the bottom of the sliding ring 3 at equal intervals in the circumferential direction, and the bottoms of the plurality of constraint plates 5 are inclined. Two connecting rods 7 are fixed to the top of the sliding ring 3, and a pressing plate 6 is fixed between the tops of the two connecting rods 7. A fixing rod 12 is fixed to the bottom of the pressing plate 6 in the middle. An adjusting chamber 24 is opened inside the fixed column 1 and passes through the top. The bottom of the fixing rod 12 extends into the inside of the adjusting chamber 24. Two push plates 13 are fixed to the bottom of the pressing plate 6. An annular sealing block 25 is slidably connected between the inner walls of the material chamber 19. The top of the annular sealing block 25 is connected to the two The push plates 13 are fixed to each other, and conical cavities 38 are provided inside the annular sealing block 25 near the edges on both sides. The inner top surfaces of the two conical cavities 38 are provided with open holes 37 that penetrate to the top of the annular sealing block 25. The pressure rod 33 is located inside the open hole 37. Conical blocks 39 are provided inside the two conical cavities 38. Bottom rods 40 are fixed to the bottoms of the two conical blocks 39. The bottoms of the two bottom rods 40 slide through to the bottom of the annular sealing block 25. Second springs 43 are fixed to the bottoms of the two conical blocks 39. The bottoms of the two second springs 43 are fixed to the inner bottom surface of the conical cavity 38. Multiple bending holes 41 are provided inside the two bottom rods 40. The top and bottom ends of the multiple bending holes 41 penetrate to the outer surface of the bottom rod 40. The tops of the multiple bending holes 41 are located inside the conical cavity 38, and the bottoms of the multiple bending holes 41 are located below the annular sealing block 25.

[0044] The effect achieved is that after the material inside the material cavity 19 is filled with material, the pressing plate 6 is pushed downward, thereby driving the sliding ring 3 to slide toward the bottom of the fixed column 1. During the sliding process, the two arc-shaped cooling plates 8 are squeezed by the inclined surface of the constraint plate 5, so that the two arc-shaped cooling plates 8 can be relatively engaged, and at the same time, the annular sealing block 25 is driven to slide downward inside the material cavity 19, so that the molten material inside the material cavity 19 is squeezed into the molding cavity 18 for pre-molding. When the annular sealing block 25 slides downward, the bottom rod 40 is lifted upward, so that the bottom outlet of the bending hole 41 near the bottom of the bottom rod 40 slides to the inside of the fixed column 1 for sealing. At this time, the conical The top conical surface of the block 39 is sealed against the top surface of the conical cavity 38. When the bottom of the fixed rod 12 slides to the side of the contact block 36, the contact block 36 will be pressed outward, thereby triggering the positioning component to position the slide plate 14. When the pushing component is reset, the annular sealing block 25 will slide upward, and when sliding, the bottom outlet of the bending hole 41 near the bottom of the bottom rod 40 will slide into the material cavity 19. At this time, the top conical surface of the conical block 39 and the top surface of the conical cavity 38 are in an open state, so that air can circulate and prevent the material cavity 19 from forming a closed state. By setting the pushing component, the cooling device, the positioning component and the sealing component can be driven to work synchronously.

[0045] like Figure 3 , Figure 5 and Fig. 9 As shown, the positioning assembly includes a guide rod 35, an inner cavity 34 is opened inside the fixed column 1 between the material cavity 19 and the forming cavity 18, the guide rod 35 is located inside the inner cavity 34, one end of the guide rod 35 slides through the inside of the adjustment cavity 24, a contact block 36 is fixed to one end of the guide rod 35, an annular plate 45 is fixed to the outer surface of the guide rod 35, a third spring 44 is fixed to one side of the annular plate 45, one end of the third spring 44 is fixed to one side of the inner wall of the inner cavity 34, a temporary storage groove 42 is opened inside the fixed column 1 at one side of the inner cavity 34, the temporary storage groove 42 is communicated with the guide groove 21, the other end of the guide rod 35 extends to the inside of the temporary storage groove 42, a pressure block 46 is provided inside the temporary storage groove 42, and the pressure block 46 and the other end of the guide rod 35 are fixed to each other.

[0046] The effect achieved is that, when the pushing component is about to discharge the material inside the material chamber 19, the contact block 36 is pushed outward by the fixed rod 12, thereby driving the guide rod 35 to slide outward, so that one side of the pressure block 46 fits against one side of the slide plate 14, and then presses the slide plate 14 to position. When the pushing component is subsequently reset, after the contact limit between the fixed rod 12 and the contact block 36, the guide rod 35 can be driven to reset under the elastic force of the third spring 44, thereby contacting the pressure block 46 to limit the slide plate 14. By setting the positioning component, the pushing component can be constrained to prevent the pushing component from vibrating when the material reaches the bottom, causing water ripples to appear on the product.

[0047] like Figure 1 , Figure 2 , Figure 4 , Figure 7 and Fig.10 As shown, the cooling device includes two arc-shaped cooling plates 8, two side frames 9 are fixed on the outer surface of the fixed column 1 near the bottom edge, guide blocks 10 are slidably connected between the inner walls on both sides of the two side frames 9, the bottoms of the two guide blocks 10 extend to the bottom of the side frames 9, the two arc-shaped cooling plates 8 are correspondingly fixed to the bottom of the guide blocks 10, and the top of the arc-shaped cooling plate 8 and the bottom of the fixed column 1 are slidably fitted with each other, one side of the two guide blocks 10 is fixed with a first spring 30, one end of the two first springs 30 is correspondingly fixed on the inner wall of one side of the side frame 9, the two arc-shaped cooling plates 8 are provided with a water storage cavity 28, one end of one of the arc-shaped cooling plates 8 Two sealing grooves 15 are provided on the side, two sealing plates 17 are fixed on one side of the other arc-shaped cooling plate 8, through openings 16 are provided on the inner bottom surface of the two sealing grooves 15 and one side of the two sealing plates 17, and the two sealing plates 17 are correspondingly sealed and clamped in the interior of the sealing grooves 15, and drainage channels 31 are provided in the interior of the two guide blocks 10, one end of the two drainage channels 31 correspondingly penetrates into the interior of the water storage chamber 28, and the other end of the two drainage channels 31 correspondingly penetrates into the outer surface of the guide block 10, and a water inlet pipe 29 is fixed on one side of the two side frames 9, one end of the two water inlet pipes 29 penetrates into the interior of the side frame 9 and is relatively connected to the other end of the drainage channel 31.

[0048] The effect achieved is that, by the mutual engagement of the two arc-shaped cooling plates 8, a constrained space identical to the molding cavity 18 can be formed, so that the preformed object can be quickly cooled when the preformed object is extruded from the molding cavity 18 to the outside. When the two arc-shaped cooling plates 8 are engaged with each other, the sealing plate 17 is sealed and engaged inside the sealing groove 15, so that the engaging parts of the two arc-shaped cooling plates 8 are in a sealed state. Then, when the two arc-shaped cooling plates 8 are slidably engaged, the guide block 10 will also slide along with it, so that the water inlet pipe 29 and one end of the drainage channel 31 are connected to each other, so that the external cooling water flow can be injected into the drainage channel 31 through the water inlet pipe 29, and finally flow into the water storage cavity 2 from the drainage channel 31. 8, in actual use, one of the water inlet pipes 29 is connected to the external water supply pipe, and the other water inlet pipe 29 is connected to the external water outlet pipe, so that water can circulate for cooling. When the cooling is completed, the component is pushed to reset, and the guide block 10 is driven to slide by the first spring 30, thereby resetting the arc cooling plate 8. During the resetting, due to the sliding of the guide block 10, the water inlet pipe 29 and one end of the drainage channel 31 are misaligned with each other, thereby cutting off the water inlet pipe 29. By setting up a cooling component, the preformed objects coming out of the molding cavity 18 can be quickly cooled, thereby avoiding a series of negative effects caused by direct contact cooling of the preformed objects with cooling water.

[0049] The main problem solved by this embodiment is: the external molten material is injected into the material cavity 19 through the feed pipe 2, and the heat is generated by the heating resistor 23 to heat and keep the molten material in the material cavity 19 warm, so as to prevent the temperature difference from causing the molten material to condense in the material cavity 19, resulting in poor fluidity. After the material in the material cavity 19 is filled, the pressing plate 6 is pushed downward, so that the sliding ring 3 can be driven to slide toward the bottom of the fixed column 1. During the sliding process, the two arc-shaped cooling plates 8 are squeezed by the inclined surface of the constraint plate 5, so that the two arc-shaped cooling plates 8 can be relatively engaged, and at the same time, the annular sealing block 25 is driven to slide downward in the material cavity 19, so that the molten material in the material cavity 19 is squeezed into the molding cavity 18 for pre-molding. When the annular sealing block 25 slides downward, the bottom rod 40 will be lifted upward, so that the bottom end outlet of the bending hole 41 near the bottom of the bottom rod 40 slides to the inside of the fixed column 1 for sealing. At this time, the top conical surface of the conical block 39 is sealed and fitted with the top surface of the conical cavity 38. When the bottom of the rod 12 slides to one side of the contact block 36, the contact block 36 will be pressed outward, thereby driving the guide rod 35 to slide outward, so that one side of the pressure block 46 and one side of the slide plate 14 are fitted with each other, and then the slide plate 14 is pressed and positioned. When resetting, after the fixed rod 12 and the contact block 36 are contacted and limited, the guide rod 35 can be driven to reset under the elastic force of the third spring 44, so that the contact pressure block 46 is pressed and limited to the slide plate 14, and the annular sealing block 25 will slide upward, so that the contact pressure block 46 is close to the bottom when sliding. The bottom exit of the bent hole 41 at the bottom of the rod 40 slides into the material cavity 19. At this time, the conical surface of the top of the conical block 39 and the top surface of the conical cavity 38 are open, so that air can circulate and prevent the material cavity 19 from forming a closed state. Under the combined movement of the above-mentioned mechanisms, the current cooling method of the cable sheath causes uneven thermal expansion and contraction of the cable sheath, thereby generating tiny concave cracks on the outer surface of the cable sheath, which will accelerate the aging and cracking of the cable sheath during subsequent use.

[0050] For example, in one embodiment, the present invention also provides a preparation process for preparing a corrosion-resistant and wear-resistant wire and cable sheath material, which is applied to a device for preparing a corrosion-resistant and wear-resistant wire and cable sheath material as above, comprising the following steps:

[0051] Step S1: inject the external molten material into the material cavity 19 through the feed pipe 2. When working, the molten material in the material cavity 19 can enter the molding cavity 18 for pre-molding through the push component. When the push component is driven, the cooling device will be driven to work, so that the pre-molded items just out of the molding cavity 18 are quickly cooled and molded. When the push component moves, the sealing component can prevent the molten material in the material cavity 19 from leaking, and the feed pipe 2 is controlled to be on and off. When the push component runs to the bottom, it is positioned by the positioning component;

[0052] Step S2: When the cooling device is working, the two arc-shaped cooling plates 8 are engaged with each other to form a confined space identical to the molding cavity 18, thereby rapidly cooling the preformed object when the preformed object is extruded from the molding cavity 18 to the outside;

[0053] Step S3: When the positioning component is working, when the pushing component is about to discharge the material in the material chamber 19, the contact block 36 is pushed outward by the fixing rod 12, thereby driving the positioning component to constrain the pushing component to prevent the pushing component from vibrating when the material reaches the bottom, causing water ripples to appear on the product;

[0054] Step S4: When the sealing component is working, the sliding sealing fit between the slide plate 14 and the sliding port 4 can prevent the material in the material cavity 19 from overflowing from the sliding port 4 when the pushing component is working, and the through hole 20 is opposite to the feed pipe 2, so that the feed pipe 2 can be controlled to be on and off;

[0055] Step S5: When the pushing component is working, the two arc-shaped cooling plates 8 are squeezed by the constraint plate 5 so that the two arc-shaped cooling plates 8 can be relatively engaged, and at the same time, the annular sealing block 25 is driven to slide downward inside the material cavity 19, so that the molten material inside the material cavity 19 is squeezed into the molding cavity 18 for pre-molding, and the positioning component can also be triggered to work.

[0056] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
