Description

Technical Field

[0001] This utility model relates to the field of calendering technology, specifically to a flat wire calendering machine. Background Technology

[0002] Flat wire rolling mill is an important industrial equipment widely used in many fields. It is used to roll raw materials into flat wires of the required thickness and width. The material of flat wires can be nickel-titanium alloy, a special alloy with excellent properties, which is widely used in aerospace, medical devices, machinery manufacturing and electronic equipment.

[0003] During the processing of nickel-titanium alloy wire in a flat wire rolling mill, pressure is applied to the raw material through one or more pairs of parallel rollers on the rolling mill to cause plastic deformation. As the rollers rotate and move relative to each other, the material is gradually stretched and compressed into the desired flat wire product. However, when the rollers compress and deform the nickel-titanium alloy, the nickel-titanium alloy is easily squeezed and produces certain debris and impurities. These debris will stick to the roller surface. When the roller rotates once and squeezes these debris and the nickel-titanium alloy, it is easy to cause the thickness of the extruded nickel-titanium alloy to be too thin, resulting in uneven thickness of the flattened nickel-titanium alloy, which affects the processing quality. Utility Model Content

[0004] The purpose of this invention is to provide a flat wire calendering machine to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A flat yarn calendering machine includes: a support frame, two mounting plates fixedly mounted on the side of the support frame by bolts, two movable plates slidably mounted on the inner wall of the support frame, and pressure rollers rotatably mounted on the two mounting plates near their sides and the two movable plates near their sides; and further includes:

[0007] The cleaning mechanism is located on one side of the pressure roller. The cleaning mechanism includes a scraper located on one side of the pressure roller. A fixing strip is fixedly installed on the side of the scraper, and a fixing sleeve is provided on one side of the fixing strip. The cleaning mechanism is used to remove impurities from the surface of the pressure roller.

[0008] The connecting mechanism is located inside the fixed sleeve. The connecting mechanism includes a locking block located inside the fixed sleeve. The mounting plate side and the moving plate side are respectively provided with locking grooves. The connecting mechanism is used for installing and removing the fixed sleeve.

The lower end of the adjustment component is rotatably connected to the top surface of the two movable plates through a bearing seat. Two pairs of fixed sleeves are provided, and the sides of the two pairs of fixed sleeves are fixedly connected to the sides of the mounting plate and the sides of the movable plates, respectively.

[0010] Preferably, the inner walls of the two pairs of fixed sleeves are rotatably mounted with connecting shafts via bearing seats, there are two scrapers, and multiple fixing strips are provided. The multiple fixing strips are fixedly connected to the outer walls of the two connecting shafts, and the sides of the two scrapers are slidably connected to the outer walls of the two pressure rollers.

[0011] Preferably, the two pairs of fixed sleeves are provided with grooves on their sides, and the outer walls of the two connecting shafts are fixedly installed with adjusting sleeves, and the outer walls of the multiple adjusting sleeves are slidably connected to the inner walls of the multiple grooves.

The adjusting sleeves exert a certain thrust on the connecting shaft, and the connecting shaft exerts a certain thrust on the fixing strip and the scraper, so that the scraper is in close contact with the outer wall of the pressure roller. The scraper removes the debris from the surface of the pressure roller, ensuring that the surface of the pressure roller is smooth and flat, thereby making the pressure roller extrude the nickel-titanium alloy more evenly and improving the processing quality.

[0018] By pressing the set locking blocks, the two locking blocks squeeze the second elastic element, causing the second elastic element to contract under the pressure. At the same time, the two locking blocks move closer to each other and release from the slot. Pulling the fixing sleeve allows the fixing sleeve and scraper to be disassembled. When the scraper wears out and is damaged after long-term use, it is convenient to replace the scraper and improves the replacement efficiency. Attached Figure Description

[0029] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] The cleaning mechanism 2 is located on one side of the pressure roller 103. The cleaning mechanism 2 includes a scraper 204 located on one side of the pressure roller 103. A fixing strip 203 is fixedly installed on the side of the scraper 204. A fixing sleeve 201 is provided on one side of the fixing strip 203. The cleaning mechanism 2 is used to remove impurities from the surface of the pressure roller 103.

[0032] Specifically, such as Figures 1-4 As shown, an adjustment component 104 is fixedly installed on the top surface of the support frame 1. The lower end of the adjustment component 104 is rotatably connected to the top surface of two movable plates 102 through a bearing seat. Two pairs of fixed sleeves 201 are provided, and the sides of the two pairs of fixed sleeves 201 are fixedly connected to the sides of the mounting plate 101 and the sides of the movable plate 102, respectively.

[0033] In this embodiment, the adjustment component 104 can drive the moving plate 102 and the upper pressure roller 103 to move up and down, thereby adjusting the distance between the two pressure rollers 103 according to the required thickness of the metal wire.

[0034] Specifically, such as Figures 1-4 As shown, the inner walls of the two pairs of fixed sleeves 201 are respectively rotatably mounted with connecting shafts 202 through bearing seats. There are two scrapers 204 and multiple fixing strips 203. The multiple fixing strips 203 are respectively fixedly connected to the outer walls of the two connecting shafts 202, and the sides of the two scrapers 204 are respectively slidably connected to the outer walls of the two pressure rollers 103.

[0035] In this embodiment, the scraper 204 is used to scrape away impurities and dust from the surface of the pressure roller 103, ensuring the cleanliness of the surface of the pressure roller 103 and improving the quality of metal wire rolling.

[0036] Specifically, such as Figures 1-4 As shown, grooves 205 are respectively opened on the sides of the two pairs of fixed sleeves 201, and adjusting sleeves 206 are respectively fixedly installed on the outer walls of the two connecting shafts 202. The outer walls of the multiple adjusting sleeves 206 are slidably connected to the inner walls of the multiple grooves 205.

[0037] In this embodiment: the groove 205 limits the adjustment sleeve 206, and the adjustment sleeve 206 applies a thrust to the connecting shaft 202.

[0038] Specifically, such as Figures 1-4 As shown, multiple adjusting sleeves 206 have arc-shaped rods 207 slidably installed on their inner walls. The two ends of the multiple arc-shaped rods 207 are fixedly connected to the inner walls of multiple grooves 205. The outer walls of the multiple arc-shaped rods 207 have elastic elements 208 slidably installed on their outer walls. The two ends of the multiple elastic elements 208 are fixedly connected to the sides of the multiple adjusting sleeves 206 and the inner walls of one side of the multiple grooves 205.

[0039] In this embodiment: the arc-shaped rod 207 further limits the adjustment sleeve 206 to ensure the stability of the rotation of the adjustment sleeve 206, and the elastic element 208 applies elastic force to the adjustment sleeve 206.

[0040] The connecting mechanism 3 is located inside the fixed sleeve 201. The connecting mechanism 3 includes a locking block 302 located inside the fixed sleeve 201. The side of the mounting plate 101 and the side of the moving plate 102 are respectively provided with a locking groove 305. The connecting mechanism 3 is used to install and remove the fixed sleeve 201.

[0041] Specifically, such as Figures 1-5 As shown, the top surfaces of the two pairs of fixed sleeves 201 are respectively provided with moving grooves 301, and multiple pairs of locking blocks 302 are provided. The sides of the multiple pairs of locking blocks 302 are slidably connected to the inner walls of multiple moving grooves 301.

[0042] In this embodiment, the movable slot 301 is used to limit the movement of the card block 302, making the movement of the card block 302 more stable.

[0043] Specifically, such as Figures 1-5 As shown, multiple pairs of locking blocks 302 are slidably installed with limiting rods 303 on their sides. The two ends of the multiple limiting rods 303 are fixedly connected to the inner walls of the two sides of multiple moving slots 301. The outer walls of the multiple limiting rods 303 are slidably installed with elastic elements 304. The two ends of the multiple elastic elements 304 are fixedly connected to the sides of the multiple pairs of locking blocks 302 that are close to each other.

[0044] In this embodiment: the limiting rod 303 further limits the locking block 302, and the elastic element 304 applies elastic force to the two locking blocks 302.

[0045] Specifically, such as Figures 1-5 As shown, multiple card slots 305 are provided, and multiple card slots 305 are respectively engaged with multiple pairs of card blocks 302.

[0046] In this embodiment, the fixed sleeve 201 can be easily installed and removed by means of the slot 305 and the block 302.

[0047] Specifically, the solution involves passing a nickel-titanium wire through the space between two pressure rollers 103. The distance between the two pressure rollers 103 is adjusted using an adjusting assembly 104. One end of the nickel-titanium wire is connected to an external pulling mechanism, which pulls the wire and causes the lower pressure roller 103 to rotate. The two pressure rollers 103 flatten the nickel-titanium wire. An elastic element 208 applies a spring force to the adjusting sleeve 206, which in turn exerts a certain thrust on the connecting shaft 202. The connecting shaft 202 then applies a certain thrust to the fixing strip 203 and the scraper 204, causing the scraper 204 to contact the outer surface of the pressure rollers 103. With the walls in close contact, the scraper 204 scrapes away debris from the surface of the pressure roller 103, ensuring the surface of the pressure roller 103 is smooth and flat, thus making the pressure roller 103 extrude the nickel-titanium alloy more evenly. When the scraper 204 is worn or damaged, the locking block 302 is pressed, and the two locking blocks 302 squeeze the elastic element 2 304. The elastic element 2 304 is compressed and contracted. At the same time, the two locking blocks 302 move closer to each other and are released from the locking groove 305. Pulling the fixing sleeve 201, the fixing sleeve 201 and the scraper 204 can be disassembled, making it convenient to replace the scraper 204 and improving the replacement efficiency.
