Description

Technical Field

[0001] This utility model relates to the field of slide rail technology, specifically a rolling die for a car door slide rail. Background Technology

[0002] Door rails are components of automotive door systems, typically made of high-strength metal or engineering plastics. These long, strip-shaped structures are installed between the door and the vehicle body. Through the cooperation of the rails and sliders, they provide stable support and precise guidance for the smooth opening and closing of the door. Door rails must bear the weight of the door and also adapt to the vibrations and bumps during vehicle operation, ensuring that the door can open and close smoothly and steadily in various environments.

[0003] The production process of car door sliding rails generally includes raw material preparation, selecting appropriate metal materials according to the performance requirements of the car door sliding rails, feeding the cut metal sheets into the rolling mold during forming, the mold applying pressure to the sheet through a series of rollers, the formed car door sliding rails need to undergo surface treatment, and finally a comprehensive quality inspection of the produced car door sliding rails.

[0004] Roll forming dies are commonly used in the forming and processing of car door slide rails. In the existing car door slide rail roll forming dies, the upper and lower dies come into contact with the raw material during roll forming, resulting in high-intensity friction. After long-term operation, wear occurs, leading to a deterioration in the roll forming effect of the dies. Therefore, a new car door slide rail roll forming die is proposed to address the above problems. Utility Model Content

A push rod; a cutter is fixedly connected to the top of the electric push rod; multiple sets of second sponges are fixedly connected to the top of the rolling table; lubricating oil is guided from the oil pipe to the first sponge through an oil pump. After the first sponge absorbs the lubricating oil, the upper mold rotates to evenly spread the lubricating oil and drip it onto the surface of the lower mold. This reduces the friction between the upper and lower molds and the sheet metal, reduces the wear of the upper and lower molds caused by long-term friction, and increases the dimensional accuracy of the rolled door slide rails during long-term operation of the upper and lower molds. This improves the rolling effect, reduces wear, and enhances the rolling effect. The cutter can cut the extruded sheet metal, enabling continuous operation of extruded sheet metal and cutting on the same equipment.

[0007] Preferably, a third support frame is fixedly connected to the top of the rolling table; a pair of spring telescopic rods are fixedly connected to the side wall of the third support frame; a guide plate is fixedly connected to the top of the spring telescopic rods; a rubber wheel is rotatably connected to the side wall of the guide plate; the rubber wheel contacts and rubs against the side of the metal sheet, which can limit the position of the sheet and ensure that the sheet is always in the correct position during the rolling process, reducing the sheet from shifting or shaking. The spring telescopic rods can retract during the guiding process and can be adaptively adjusted according to the spacing of different sized sheets. The elasticity and flexibility of the rubber wheel can also reduce friction and damage to the surface of the sheet when it comes into contact with the metal sheet.

[0008] Preferably, a sliding shaft is fixedly connected to the top of the rolling table; a pair of sliding seats are slidably connected to the top of the sliding shaft; a grinding shaft is fixedly connected to the top of the sliding seats; by grinding the burrs on the side of the metal sheet after extrusion molding, the edge of the sheet can be made smoother and flatter, improving the appearance quality and dimensional accuracy of the door slide rail, and reducing the presence of burrs.

[0009] Preferably, an air pump is fixedly connected to the top of the second support frame; an air outlet is fixedly connected to the side wall of the air pump; cooling through the air outlet can keep the grinding shaft in a better working state, reduce the decline in grinding performance of the grinding shaft due to overheating, and cooling the deburring area through the air outlet can also reduce the deformation of the board due to high temperature.

[0010] Preferably, a collection box is fixedly connected to the side wall of the rolling table; the collection box is located at one end near the second support frame; a buffer pad is fixedly connected inside the collection box; the buffer pad can buffer the impact force when the cut board falls, reduce the noise generated by the board directly hitting the collection box, and also reduce the deformation or damage of the board due to the impact force, thereby improving product quality.

[0011] Preferably, a fourth support frame is fixedly connected to the top of the rolling table; a cleaning brush is fixedly connected to the middle of the fourth support frame; by contacting the surface of the board with the cleaning brush, dust and contaminants on the surface of the board are effectively removed, reducing the contaminants from following the board into the upper and lower molds for extrusion, which would cause contaminants to penetrate the surface of the board and damage it.

[0012] The advantages of this utility model are:

[0013] 1. The door slide rail rolling die of this utility model guides lubricating oil from the oil pipe to the first sponge through an oil pump.

The cutter can cut the extruded sheet metal, enabling continuous operation of extruded sheet metal and cutting on the same equipment.

[0014] 2. The door slide rail rolling die of this utility model can limit the position of the sheet metal by contacting and rubbing the rubber roller with the side of the sheet metal, ensuring that the sheet metal is always in the correct position during the rolling process and reducing the offset or shaking of the sheet metal. The spring telescopic rod can retract during the guiding process and can be adaptively adjusted according to the spacing of sheet metal of different sizes. The elasticity and flexibility of the rubber roller can also reduce the friction and damage to the surface of the sheet metal when in contact with it. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 5As shown in the figure, a door slide rail rolling die of this utility model includes a rolling table 1; multiple sets of first support frames 11 are fixedly connected to the top of the rolling table 1; an oil pump 12 is fixedly connected to the top of the first support frame 11; a cylinder 13 is fixedly connected to the top of the first support frame 11; a first sponge 14 is fixedly connected to the output end of the cylinder 13; an oil pipe 15 is fixedly connected to the side wall of the oil pump 12; the oil pipe 15 is connected to the first sponge 14; an upper die 16 is rotatably connected to the side wall of the first support frame 11; a lower die 17 is rotatably connected to the side wall of the first support frame 11; the upper die 16 and the lower die 17 are correspondingly arranged; the top of the rolling table 1... A second support frame 18 is fixedly connected to one end; an electric push rod 19 is fixedly connected to the middle of the second support frame 18; a cutter 110 is fixedly connected to the top of the electric push rod 19; multiple sets of second sponges 111 are fixedly connected to the top of the rolling table 1; during operation, the oil pump 12 is started, and the oil pump 12 guides lubricating oil from the oil pipe 15 to the first sponge 14. The first sponge 14 absorbs the lubricating oil, pushing the cylinder 13 to move the first sponge 14 downward, so that the cylinder 13 contacts the upper mold 16. The upper mold 16 and the lower mold 17 rotate. After the upper mold 16 contacts the first sponge 14, the lubricating oil on the surface of the first sponge 14 will be applied to the surface of the upper mold 16. The rotation evenly spreads lubricating oil on the surface, and the lubricating oil drips from the upper mold 16 onto the surface of the lower mold 17. The lower mold 17 continues to rotate and comes into contact with the second sponge 111. The second sponge 111 evenly spreads the lubricating oil on the surface of the lower mold 17. After lubricating the surfaces of the upper mold 16 and the lower mold 17, the cut metal sheet is passed through the middle of the upper mold 16 and the lower mold 17, and the metal sheet is extruded. After the metal sheet passes through the upper mold 16 and the lower mold 17 multiple times, it is pressed and shaped. The shaped sheet is guided to the second support frame 18, and the electric push rod 19 is pushed to drive the cutter 110 to fall, pressing the extruded sheet. Cutting is performed; lubricating oil is guided from oil pipe 15 to first sponge 14 through oil pump 12. After the first sponge 14 absorbs the lubricating oil, the upper mold 16 rotates to evenly spread the lubricating oil and drip it onto the surface of lower mold 17. This reduces the friction between the upper mold 16 and lower mold 17 and the sheet material, reduces the wear of the upper mold 16 and lower mold 17 caused by long-term friction, and increases the dimensional accuracy of the rolled door slide rail during long-term operation of the upper mold 16 and lower mold 17. This improves the rolling effect, reduces wear, and enhances the rolling effect. The cutter 110 can cut the extruded sheet material, enabling continuous operation of extruded sheet material and cutting on the same equipment.

[0025] like Figure 1 and Figure 3As shown, a third support frame 2 is fixedly connected to the top of the rolling table 1; a pair of spring telescopic rods 21 are fixedly connected to the side wall of the third support frame 2; a guide plate 22 is fixedly connected to the top of the spring telescopic rods 21; a rubber roller 23 is rotatably connected to the side wall of the guide plate 22; during operation, when the metal sheet is extruded in the middle of the upper mold 16 and the lower mold 17, it passes through the middle of the guide plate 22, and the side of the sheet comes into contact with and rubs against the rubber roller 23. The rubber roller 23 rotates to limit and guide the sheet. During the guiding process, the spring telescopic rods 21 retract, which can adapt to the spacing of different sizes of sheet metal; through the contact and friction between the rubber roller 23 and the side of the metal sheet, the sheet metal can be limited, ensuring that the sheet metal is always in the correct position during the rolling process, reducing the sheet metal from shifting or shaking. The spring telescopic rods 21 can retract during the guiding process, which can adaptively adjust according to the spacing of different sizes of sheet metal. The elasticity and flexibility of the rubber roller 23 can also reduce the friction and damage to the surface of the sheet metal when in contact with it.

[0026] like Figure 1 and Figure 4 As shown, a sliding shaft 3 is fixedly connected to the top of the rolling table 1; a pair of sliding seats 31 are slidably connected to the top of the sliding shaft 3; a grinding shaft 32 is fixedly connected to the top of the sliding seat 31; during operation, after the metal sheet is extruded, there are burrs on the side. The pair of sliding seats 31 are pushed to adjust the distance between the grinding shafts 32 so that the grinding shafts 32 are in close contact with the side of the sheet. The grinding shafts 32 are started to rotate. When the sheet is extruded and guided, the side of the sheet contacts the grinding shaft 32, and the grinding shaft 32 grinds the side of the sheet to remove the burrs. By grinding and removing the burrs on the side of the metal sheet after extrusion by the grinding shaft 32, the edge of the sheet can be made smoother and flatter, improving the appearance quality and dimensional accuracy of the door slide rail and reducing the presence of burrs.

[0027] like Figure 1 and Figure 4 As shown, an air pump 4 is fixedly connected to the top of the second support frame 18; an air outlet 41 is fixedly connected to the side wall of the air pump 4; during operation, the grinding shaft 32 generates a high temperature when deburring the side of the board. The air pump 4 is started, which drives the air outlet 41 to blow air onto the deburring area of ​​the grinding shaft 32 to cool down the deburring area of ​​the board side wall and clean the contaminants on the surface of the board. Cooling down through the air outlet 41 can keep the grinding shaft 32 in a better working state and reduce the decline in grinding performance of the grinding shaft 32 due to overheating. Cooling down the deburring area through the air outlet 41 can also reduce the deformation of the board due to high temperature.

[0028] like Figure 1 and Figure 5As shown, a collection box 5 is fixedly connected to the side wall of the rolling table 1; the collection box 5 is located at one end near the second support frame 18; a buffer pad 51 is fixedly connected inside the collection box 5; during operation, the board material cut by the cutter 110 can fall into the collection box 5, and after the board material falls into the collection box 5, it comes into contact with the buffer pad 51, which can buffer the impact force when the board material falls; the buffer pad 51 can buffer the impact force when the board material falls after cutting, reduce the noise generated by the board material directly hitting the collection box 5, and also reduce the deformation or damage of the board material due to the impact force, thereby improving product quality.

[0029] like Figure 1 As shown, a fourth support frame 6 is fixedly connected to the top of the rolling table 1; a cleaning brush 61 is fixedly connected to the middle of the fourth support frame 6; during operation, when the cut metal sheet enters the upper mold 16 and lower mold 17 for extrusion molding, it passes through the middle of the fourth support frame 6, and the surface of the metal sheet comes into contact with the cleaning brush 61 to clean the surface of the sheet before sending it into multiple sets of second support frames 18; through the contact between the cleaning brush 61 and the surface of the sheet, dust and contaminants on the surface of the sheet are effectively removed, reducing the risk of contaminants following the sheet into the upper mold 16 and lower mold 17 for extrusion, which would cause contaminants to penetrate the surface of the sheet and damage it.

[0030] Working principle: When oil pump 12 is started, it guides lubricating oil from oil pipe 15 to the first sponge 14. The first sponge 14 absorbs the lubricating oil, pushing cylinder 13 to move the first sponge 14 downwards, allowing cylinder 13 to contact the upper mold 16. The upper mold 16 and lower mold 17 rotate. After the upper mold 16 contacts the first sponge 14, the lubricating oil on the surface of the first sponge 14 is applied to the surface of the upper mold 16. The rotation of the upper mold 16 evenly spreads the lubricating oil on its surface. The lubricating oil drips from the upper mold 16 onto the surface of the lower mold 17. The lower mold 17 continues to rotate and contacts the second sponge 111. Sponge 111 evenly applies lubricating oil to the surface of the lower mold 17. After lubricating the surfaces of the upper mold 16 and the lower mold 17, the cut metal sheet is passed through the middle of the upper mold 16 and the lower mold 17, and the metal sheet is extruded. After the metal sheet passes through the upper mold 16 and the lower mold 17 multiple times, it is pressed and shaped. The shaped sheet is guided to the second support frame 18, and the electric push rod 19 is pushed to drive the cutter 110 to fall and cut the extruded sheet. When the metal sheet is extruded in the middle of the upper mold 16 and the lower mold 17, it passes through the middle of the guide plate 22, and the side of the sheet is... Rubber rollers 23 engage in contact friction, and their rotation guides and limits the movement of the sheet metal. During this guiding process, the spring telescopic rod 21 retracts, accommodating different sheet metal spacings. After extrusion molding, the metal sheet may have burrs on its sides. Pushing a pair of sliding seats 31 adjusts the spacing between the grinding shafts 32, ensuring they are flush against the sheet metal sides. The grinding shafts 32 then rotate, and during extrusion guidance, their sides contact the grinding shafts 32, which then grind the sides to remove burrs. The grinding shafts 32 generate high temperatures during this deburring process. The air pump 4 is started, and the air outlet 41 is directed to blow air onto the deburring area of ​​the grinding shaft 32 to cool down the deburring area of ​​the board side wall and clean the contaminants on the board surface. The board cut by the cutter 110 can fall into the collection box 5. After the board falls into the collection box 5, it comes into contact with the buffer pad 51. The buffer pad 51 can buffer the impact force when the board falls. When it enters the upper mold 16 and the lower mold 17 for extrusion molding, the cut metal board passes through the middle of the fourth support frame 6. The surface of the metal board comes into contact with the cleaning brush 61 to clean the surface of the board and send it into the multiple sets of second support frames 18.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
