Description

Technical Field

[0001] This application relates to the technical field of tin bar rolling, and in particular to a tin bar rolling apparatus. Background Technology

[0002] Solder bar rolling is a process that uses a rolling mill to process metallic tin or tin alloy materials, such as solder wire and tin bars, into specific shapes and sizes. During the rolling process, the metal material is squeezed and deformed by multiple passes of rolls to gradually reach the target specifications.

[0003] The existing publication number CN203991661U, entitled "A Rolling Mechanism for a Solder Wire Rolling Mill," includes a roll box, a roll shaft, bearings, and rolls. The roll shaft is mounted on the roll box and supported by the bearings. A roll mounting seat is provided on the roll shaft, and the roll mounting seat has multiple connecting holes for connecting the rolls. Multiple wire grooves are provided on the outer surface of the rolls, and an elastic telescopic device is provided inside for connecting with the connecting holes. This rolling mechanism greatly improves the utilization rate of the rolls, eliminating the need for frequent roll replacements and reducing the manufacturer's expenses.

[0004] Regarding the aforementioned related technologies, the inventors discovered that when the solder wire rolling mill is used to produce solder bars, the installation positions of the ends of the two parallel rolling shafts on the frame are fixed and cannot be adjusted. The rolling distance between adjacent rolling shafts is fixed, making it impossible to adjust the distance between the two rolling shafts according to the specific processing size specifications of the solder bars. This makes it impossible to adapt to the processing requirements of solder wires of different diameters, resulting in insufficient rolling flexibility. Utility Model Content

[0005] To overcome the limitations of existing rolling devices where the distance between two adjacent rolling shafts is fixed, making it impossible to adjust the distance between the two rolling shafts according to the specific processing dimensions of the solder bar, thus failing to meet the processing requirements of solder wires of different diameters and resulting in insufficient rolling flexibility, this application provides a rolling device for solder bars.

[0006] The rolling device for tin bars provided in this application adopts the following technical solution: A rolling device for tin bars includes a frame, a sliding plate is horizontally fixed in the middle of the vertical end face of the rear side of the frame, and rod seats are vertically fixed in the rear sides of the top surface of the frame, and two clamping rollers are horizontally arranged on the rod seats along the vertical direction. A rolling assembly is installed above the frame. The rolling assembly includes a slide block, a slide frame, and a roll body. The slide block is horizontally slidably assembled on the slide plate, and a slide frame is vertically fixed on the top surface of the slide block. A lifting slider is vertically slidably assembled in the slide groove of the slide frame, and a rotating drum is horizontally rotatably connected to the front end face of both the slide frame and the lifting slider. Two roll bodies are horizontally arranged in the vertical direction, and one end of each roll body is fixed in the rotating drum of the slide frame and the lifting slider, respectively. A rolling motor is horizontally fixed on the rear end face of the slide frame and the lifting slider, and the output end of the rolling motor is fixed to the end of the rotating drum.

[0007] By adopting the above technical solution, the clamping rollers on the rod seat are used to fix the position of the solder bar, ensuring that the solder bar will not slip during the rolling process; the cooperation between the slide plate and the slide block allows the rolling components to move horizontally, so as to adjust the position of the solder bar on the frame for later rolling processing; the combination of the slide frame and the lifting slider through the vertical slide groove adjusts the rolling distance between the two adjacent roll bodies, which is suitable for rolling different specifications of solder bars and meets the processing requirements of solder bars of different thicknesses; the rotating drum, as a key component, is driven by the rolling motor to make the roll body rotate, thereby flattening or plastically deforming the solder bar; one end of the two roll bodies is fixed in the rotating drum of the slide frame and the lifting slider, so that they can move relative to each other in the vertical direction, thereby effectively changing the pressure applied to the solder bar and achieving precise control of the solder bar; the rolling motor provides power, which drives the roll body to rotate through the rotating drum, and finally completes the rolling processing of the solder bar.

[0008] Optionally, one end of each of the two clamping rollers is rotatably connected to a rotating hole seat, and the rotating hole seat is vertically slidably inserted into the rod seat.

[0009] By adopting the above technical solution, the clamping roller can be flexibly adjusted in position and angle through the rotating connection between the rotating hole seat and the clamping roller, while the vertical sliding of the rotating hole seat on the rod seat enables it to move precisely in the vertical direction, thereby realizing the clamping and releasing operation of materials of different heights.

[0010] Optionally, a pull-down spring is vertically fixed on the rod seat, and the other end of the pull-down spring is fixed on the rotating hole seat.

[0011] By adopting the above technical solution, the pull-down spring vertically installed on the rod seat generates a downward pulling force through its other end fixedly connected to the rotating hole seat, so that the entire rolled tin bar remains tight and stable.

[0012] Optionally, an adjusting screw is installed through a vertical thread on the top surface of the slide frame, and the bottom end of the adjusting screw is rotatably connected to the top surface of the lifting slider.

[0013] By adopting the above technical solution, the bottom end of the adjusting screw is connected to the top of the lifting slider through a rotary joint, which allows the adjusting screw to drive the lifting slider to make fine adjustments in the vertical direction. By rotating the adjusting screw, the rolling distance between adjacent roll bodies of the two roll bodies can be adjusted, thereby meeting the thickness rolling requirements of the tin bar device.

[0014] Optionally, the roll body includes an assembly rod, one end of which is horizontally fixed with a threaded post, and the threaded post has vertically opened threaded grooves on both the upper and lower sides. The threaded post of the assembly rod is inserted into the rotating drum, and the upper and lower sides of the rotating drum are vertically threaded with locking bolts, and the locking bolts are threaded in the threaded grooves of the threaded post.

[0015] By adopting the above technical solution, a threaded post is horizontally fixed to one end of the assembly rod. The threaded post has vertically formed threaded grooves on its upper and lower sides, allowing for the horizontal assembly of the rolls. The rotating drum serves as a connecting component, with vertically threaded holes on both its upper and lower sides, which can be used in conjunction with the threaded post. Locking bolts are threaded through the threaded holes in the rotating drum and the threaded grooves in the threaded post, not only fixing the positions of the assembly rod and the rotating drum but also ensuring a tight connection between the two components, thus guaranteeing the stability and reliability of the entire roll system. This structural design not only improves the efficiency of roll assembly and disassembly but also enhances the overall stability of the system.

[0016] Optionally, multiple dividing sleeves are horizontally inserted into the outside of the assembly rod, and the dividing sleeves are available in various length specifications.

[0017] By adopting the above technical solution, multiple dividing sleeves are horizontally sleeved on the outside of the assembled insert rod. One end of each dividing sleeve is equipped with a retaining ring. The retaining rings on adjacent dividing sleeves form solder bar rolling grooves to accommodate solder bar rolling requirements of different widths. The dividing sleeves are available in various length specifications, allowing for free adjustment of the rolling width within a certain range according to actual needs, improving assembly accuracy and versatility. In terms of working principle, when the structural length needs to be adjusted, the dividing sleeves are simply inserted into different positions along the axial direction of the insert rod. This allows for quick adjustment of the width of adjacent dividing sleeves to meet solder bar rolling width requirements.

[0018] Optionally, the other end of the assembly rod is horizontally fixed with a stud, and the stud is threaded with a cap for pressing multiple separator sleeves onto the assembly rod.

[0019] By adopting the above technical solution, the assembly rod provides support, the stud ensures the accurate position of the separator sleeve, the separator sleeve effectively separates the space of the rolled solder bar, and the screw cap ensures the stable position of the separator sleeve on the assembly rod through the tightening force of the thread, thereby realizing the precise assembly of the structure and the stable separation function.

[0020] Optionally, a positioning rod is horizontally slidably inserted into the vertical end face of the rear side of the slide frame, and the positioning rod is inserted into the locking hole of the slide plate. A positioning spring is sleeved on the outside of the positioning rod, and the two ends of the positioning spring are respectively fixed to the ends of the slide frame and the positioning rod.

[0021] By adopting the above technical solution, when it is necessary to tightly connect the sliding frame and the slide plate, the positioning rod can be manually pushed to slide horizontally into the slot of the slide plate, at which time the positioning spring is compressed; when the positioning rod is fully inserted into the slot, the positioning spring returns to its original state, and the positioning rod is pushed to keep it stably in the slot, thus achieving a tight connection.

[0022] In summary, this application includes at least one of the following beneficial technical effects: First, based on the width and space requirements for solder bar rolling, multiple dividing sleeves are horizontally fitted outside the insert rod. One end of each dividing sleeve has a retaining ring, and the retaining rings on adjacent dividing sleeves form solder bar rolling grooves to accommodate different width solder bars. The dividing sleeves are available in various lengths, allowing for flexible adjustment of the rolling width within a certain range according to actual needs. Then, the threaded insert at one end of the assembled roll body is inserted. The threaded insert has vertically opened threaded grooves on both the upper and lower sides, allowing the roll body to be assembled laterally. The rotating drum serves as a connecting component, with vertically threaded holes on both the upper and lower sides, which can be used in conjunction with the threaded insert. Locking bolts are threaded through the threaded holes of the rotating drum and the threaded grooves of the threaded insert, fixing the roll body and the rotating drum in place. Secondly, according to the actual width requirement of the rolled solder bar, the adjusting screw is rotated. The bottom end of the adjusting screw is connected to the top of the lifting slider through a rotary joint, which allows the adjusting screw to drive the lifting slider to make fine adjustments in the vertical direction, thereby adjusting the rolling distance between adjacent roll bodies of the two roll bodies, so as to meet the thickness rolling requirements of the solder bar device.

[0025] The present application will be further described in detail below with reference to the accompanying drawings.

[0026] This application discloses a rolling apparatus for solder bars. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 5 A solder bar rolling device includes a frame 1. A slide plate 11 is horizontally fixed to the middle of the vertical end face of the rear side of the frame 1, and rod seats 12 are vertically fixed to the rear sides of the top surface of the frame 1. Two clamping rollers 14 are horizontally arranged on the rod seats 12 along the vertical direction. The frame 1 of this rolling device supports the structure of the entire equipment and provides a stable foundation. The slide plate 11 is fixed to the rear side of the frame and can provide translational movement guidance for the rolling component 2 of the solder bar to be rolled laterally, ensuring that the rolling component 2 can stably move laterally along a predetermined path on the frame 1 to adjust the rolling position during rolling. The rod seats 12 are vertically fixed to both sides of the top surface of the frame 1 and provide installation positions for the clamping rollers 14. The clamping rollers 14 are horizontally arranged on the rod seats 12 and are used to clamp the solder bar for conveying, preventing the solder bar from shifting during the rolling process, thereby ensuring the rolling quality. A rolling assembly 2 is provided above the frame 1. The rolling assembly 2 includes a slide block 21, a slide frame 22, and a roll body 26. The slide block 21 is horizontally slidably assembled on the slide plate 11, and the slide frame 22 is vertically fixed on the top surface of the slide block 21. A lifting slider 23 is vertically slidably assembled in the slide groove of the slide frame 22, and a rotating drum 24 is horizontally rotatably connected to the front end face of both the slide frame 22 and the lifting slider 23. Two roll bodies 26 are horizontally arranged in the vertical direction, and one end of each roll body 26 is fixed to the slide frame 22 and the lifting slider 23, respectively. In the rotating drum 24 of the slider 23, a rolling motor 27 is horizontally fixed on the rear end face of the sliding frame 22 and the lifting slider 23, and the output end of the rolling motor 27 is fixed at the end of the rotating drum 24. The cooperation between the sliding block 21 and the sliding plate 11 allows the components to slide horizontally, thereby providing translational motion guidance for the rolling component 2 of the later rolling of solder bars, ensuring that the rolling component 2 can stably move laterally along the predetermined path on the frame 1 to adjust the rolling position during rolling. The sliding frame 22 provides a stable support structure and mounts two roll bodies 26. The lifting slider 23 slides vertically through the sliding groove of the sliding frame 22 to ensure the rolling height of the upper roll body 26 and adjust the rolling spacing between adjacent roll bodies 26 to meet the rolling requirements of different specifications of solder bars. The rotating drum 24 at the front end of the sliding frame 22 and the lifting slider 23 transmits the rotational motion to the roll body 26 through a mechanical connection to carry out the rolling operation. The rolling motor 27 at the rear end of the sliding frame 22 and the lifting slider 23 provides power to the rotating drum 24, driving the rolling roll body 26 to generate the required rotational force during the rolling process, thereby achieving efficient rolling of the tin bar. The clamping rollers on the rod holder are used to fix the position of the solder bar, ensuring that the solder bar will not slip during the rolling process; the cooperation between the slide plate and the slide block allows the rolling components to move horizontally, so as to adjust the position of the solder bar on the frame 1 for later rolling processing; the combination of the slide frame and the lifting slider adjusts the rolling distance between the two adjacent roll bodies 26 through the vertical slide groove, which is suitable for rolling different specifications of solder bars to meet the processing requirements of solder bars of different thicknesses; the rotating drum, as a key component, is driven by the rolling motor to make the roll body rotate, thereby flattening or plastically deforming the solder bar; one end of the two roll bodies is fixed in the rotating drum of the slide frame and the lifting slider, so that they can move relative to each other in the vertical direction, thereby effectively changing the pressure applied to the solder bar and achieving precise control of the solder bar; the rolling motor provides power, which drives the roll body to rotate through the rotating drum, and finally completes the rolling processing of the solder bar.

[0027] Reference Figure 5Two clamping rollers 14 are rotatably connected at one end to a rotating seat 13, which is vertically slidably inserted into a rod seat 12. The rotating seat 13 plays a crucial connecting role; its rotatable connection to the two clamping rollers 14 ensures that the rollers can rotate flexibly and perform clamping or releasing operations on materials. The rod seat 12 provides a vertical sliding guide for the rotating seat 13, allowing it to move smoothly in the vertical direction to adapt to the material handling needs of different heights. The two clamping rollers 14 work together to clamp or release materials as needed, achieving precise material fixation and operation. The overall working principle is as follows: through the rotatable connection between the rotating seat 13 and the clamping rollers 14, the clamping rollers can flexibly adjust their position and angle, while the vertical sliding of the rotating seat 13 on the rod seat 12 allows it to move precisely in the vertical direction, thereby achieving clamping and releasing operations on materials of different heights.

[0028] Reference Figure 5 A pull-down spring 15 is vertically fixed to the rod holder 12, with its other end fixed to the rotating hole seat 13. The rod holder 12 supports and secures the rod, keeping it stable in the required position. The pull-down spring 15 provides a downward pulling force by being vertically fixed to the rod holder 12, which helps to keep the rolled solder bar in the correct tightness. The rotating hole seat 13 ensures that the spring force can be transmitted and act on the required position by fixing the other end of the pull-down spring 15, thereby achieving the tightness effect of the rolled solder bar. The overall working principle is: the pull-down spring 15, vertically mounted on the rod holder 12, generates a downward pulling force through its fixed connection with the rotating hole seat 13, keeping the entire rolled solder bar tight and stable.

[0029] Reference Figure 3 An adjusting screw 25 is vertically threaded through the top surface of the sliding frame 22, and the bottom end of the adjusting screw 25 is rotatably connected to the top surface of the lifting slider 23. The sliding frame 22 serves as a support structure, providing a stable support surface, and its top surface has a vertical thread for easy adjustment with the adjusting screw 25. The adjusting screw 25 is connected to the sliding frame 22 via the vertical thread and can move up and down within a certain range. The bottom end of the adjusting screw 25 is connected to the top of the lifting slider 23 via a rotary joint, allowing the adjusting screw 25 to drive the lifting slider 23 for fine-tuning in the vertical direction. By rotating the adjusting screw 25, the rolling gap between adjacent roll bodies 26 can be adjusted, thereby meeting the thickness rolling requirements of the tin bar device.

[0030] Reference Figure 4The roll body 26 includes an assembly rod 261. One end of the assembly rod 261 is horizontally fixed with a threaded post 262, and both the upper and lower sides of the threaded post 262 have vertically formed threaded grooves. The threaded post 262 of the assembly rod 261 is inserted into the rotating drum 24, and both the upper and lower sides of the rotating drum 24 are vertically threaded with locking bolts 241, which are threaded into the threaded grooves of the threaded post 262. The roll body 26 achieves modular assembly and disassembly through the assembly rod 261, making maintenance and replacement more convenient. The threaded post 262 is horizontally fixed at one end of the assembly rod 261, and the threaded post 262 has vertically formed threaded grooves on both the upper and lower sides, allowing for the horizontal assembly of the roll. The rotating drum 24 serves as a connector, with vertically threaded holes on both the upper and lower sides that can be used in conjunction with the threaded post 262. Locking bolts 241 are threaded through and assembled into the threaded holes of the rotating drum 24 and the threaded grooves of the threaded insert 262. This not only fixes the position of the assembly rod 261 and the rotating drum 24 but also ensures a tight connection between the two components, thereby guaranteeing the stability and reliability of the entire roll system. This structural design not only improves the efficiency of roll assembly and disassembly but also enhances the overall stability of the system. Multiple partition sleeves 263 are laterally sleeved and inserted onto the outside of the assembly rod 261, and the partition sleeves 263 are available in various lengths. The main function of the assembly rod 261 is as a basic structural component for building structures of various shapes and sizes, providing great adaptability and flexibility through its length and connectivity. The multiple partition sleeves 263, which are laterally sleeved on the outside, have retaining rings at one end. The retaining rings on adjacent partition sleeves 263 form solder bar rolling grooves to accommodate different width solder bar rolling requirements. The dividing sleeves 263 are available in various lengths, allowing for flexible adjustment of the rolling width within a certain range to meet actual needs, thus improving assembly precision and versatility. In terms of working principle, when adjusting the structural length, the dividing sleeves 263 are simply inserted into different positions along the axial direction of the insert rod. This allows for quick adjustment of the width of adjacent dividing sleeves 263, suitable for solder bar rolling width requirements. The other end of the assembly insert rod 261 is horizontally fixed with a stud 264, and the stud 264 is threaded with a cap 265 for pressing the multiple dividing sleeves 263 onto the assembly insert rod 261. The main function of the assembly insert rod 261 is as a load-bearing component, used to connect and fix other parts; the stud 264, horizontally fixed at one end of the assembly insert rod 261, serves a positioning and guiding function; the multiple dividing sleeves 263 are pressed onto the assembly insert rod 261 through the threads on the stud 264, achieving internal space separation while preventing relative movement at the separation points. The screw cap 265 is screwed onto the stud 264 by threads to press and fix the partition sleeve 263, ensuring its position is fixed.The overall working principle is as follows: the assembly rod 261 provides support, the stud 264 ensures the accurate position of the separator sleeve 263, the separator sleeve 263 effectively separates the space of the rolled solder bar, and the screw cap 265 ensures the stable position of the separator sleeve 263 on the assembly rod 261 through the tightening force of the thread, thereby realizing the precise assembly of the structure and the stable separation function.

[0031] Reference Figure 3 and Figure 5 A positioning rod 28 is horizontally slidably inserted into the vertical end face of the sliding frame 22, and the positioning rod 28 is inserted into the locking hole of the slide plate 11. A positioning spring 29 is sleeved on the outside of the positioning rod 28, and the two ends of the positioning spring 29 are respectively fixed to the ends of the sliding frame 22 and the positioning rod 28. The positioning rod 28 is horizontally slidable on the vertical end face of the sliding frame 22 and is fixed to the slide plate 11 through the locking hole. The positioning spring 29 sleeved on the outside of the positioning rod 28 plays a reset role, ensuring that the sliding frame 22 and the slide plate 11 can be tightly fixed. Specifically, the sliding frame 22 is part of the overall frame, and the positioning rod 28 is the key component to achieve precise alignment and locking between the two. By sliding horizontally into the locking hole of the slide plate 11, it ensures accurate positioning. The positioning spring 29 provides a reset force to ensure that the positioning rod 28 can automatically reset when not operated, maintaining a safe locked state. The overall working principle is that when it is necessary to tightly connect the sliding frame 22 and the slide plate 11, the positioning rod 28 can be manually pushed to slide horizontally into the locking hole of the slide plate 11, at which time the positioning spring 29 is compressed; when the positioning rod 28 is fully inserted into the locking hole, the positioning spring 29 returns to its original state, pushes the positioning rod 28 to keep it stably in the locking hole, and achieves a tight connection.

[0032] The implementation principle of a rolling device for tin bars in this application is as follows: First, based on the width and space requirements for solder bar rolling, multiple dividing sleeves 263 are laterally fitted onto the outside of the insert rod 261. One end of each dividing sleeve 263 is equipped with a retaining ring. The retaining rings on adjacent dividing sleeves 263 form solder bar rolling grooves to accommodate different width solder bars. The dividing sleeves 263 are available in various lengths, allowing for free adjustment of the rolling width within a certain range according to actual needs. Then, the threaded insert 262 at one end of the assembled roll body 26 is inserted. The threaded insert 262 has vertically opened threaded grooves on its upper and lower sides, which allows the roll body 26 to be assembled laterally. The rotating drum 24 serves as a connecting component, and it has vertically threaded holes on both its upper and lower sides, which can be used in conjunction with the threaded insert 262. The locking bolt 241 is threaded through and assembled into the threaded hole of the rotating drum 24 and the threaded groove of the threaded insert 262, fixing the roll body 26 and the rotating drum 24 in place. Secondly, according to the actual width requirement of the rolled solder bar, the adjusting screw 25 is rotated. The bottom end of the adjusting screw 25 is connected to the top of the lifting slider 23 through a rotary joint, allowing the adjusting screw 25 to drive the lifting slider 23 to make fine adjustments in the vertical direction, thereby adjusting the rolling distance between the two adjacent roller bodies 26 and thus achieving the thickness rolling requirement of the solder bar device. Finally, the solder bar to be rolled is guided down from the two clamping rollers 14 on one side of the frame 1 and clamped and conveyed towards the rolling component 2. The rolling motor 27 is started to drive the two roll bodies 26 to roll the solder bar. After the solder bar to be rolled is rolled between the two roll bodies 26, it is discharged from the two clamping rollers 14 on the other side of the frame 1, thus completing the rolling of the solder bar.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
