Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a plate rolling machine with a guiding device. Background Technology

[0002] In the field of metal processing, plate rolling machines are key equipment widely used to roll metal sheets into various cylindrical, arc or conical workpieces. Traditional plate rolling machines often lack effective guiding devices or have poor guiding accuracy when the sheet enters the rolling area. Therefore, a plate rolling machine with a guiding device is particularly needed.

[0003] A plate rolling machine with a guiding device, authorized by announcement number CN207103507U, includes a frame, a power unit, an upper pressure roller, two lower pressure rollers on both sides, and a lifting device. The two lower pressure rollers are located on either side below the upper pressure roller. Both the upper and lower pressure rollers are rotatably connected to the frame. A lifting device is located on one side of the frame to control the raising and lowering of the upper pressure roller. A power unit is also located on one side of the frame. Guiding devices are symmetrically arranged on the frame outside the upper pressure roller and the left lower pressure roller. These guiding devices are detachably connected to the frame and include a base with a telescopic rod connected to it. A guide groove is provided at the end of the telescopic rod, with one end of the guide groove being trumpet-shaped and the other end being horizontal or arc-shaped. This plate rolling machine with a guiding device on one side guides the plate before it enters between the upper and lower pressure rollers, preventing tilting and jamming during the rolling process, thus improving production efficiency and product quality. However, in production, the plate thickness varies, and thinner plates are prone to deviation within the guiding device.

[0004] To address the aforementioned problems, a plate rolling machine with a guiding device is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a plate rolling machine with a guiding device to solve the problems of the existing plate rolling machines with guiding devices mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a plate rolling machine with a guiding device, comprising a machine body, a guiding mechanism on the top of the machine body, and adjusting mechanisms on both sides of the machine body;

[0007] The guiding mechanism includes mounting seats installed on both sides of the top of the machine body. The inner wall of the mounting seat is provided with a slider, the bottom of the mounting seat is provided with a groove, a lower guide wheel is provided on one side of the mounting seat, an upper guide wheel is provided on one side of the slider, and a baffle is provided on one side of the bottom of the slider.

[0008] Preferably, the guiding mechanism further includes a limiting post installed on the inner wall of the mounting base, the inner wall of the mounting base is provided with a first threaded rod, and the connecting end of the first threaded rod is provided with a first drive motor.

[0009] Preferably, the baffle is disposed on the inner wall of the groove to limit the position of the plate.

[0010] Preferably, there are two sets of limiting posts, and the limiting posts pass through the slider and are slidably connected to the slider. The first threaded rod passes through the slider and is threadedly connected to the slider.

[0011] Preferably, both the upper and lower guide wheels are provided in two sets, and the guiding mechanism is provided in two locations.

[0012] Preferably, the adjustment mechanism includes side plates installed on both sides of the machine body, a lower pressure roller is provided on the top of the machine body, an upper pressure roller is provided between the side plates and the upper pressure roller is located above the lower pressure roller, an adjustment block is slidably connected to the inner wall of the side plate, an electromagnetic coil is provided in the inner layer of the upper pressure roller, a second threaded rod is provided through the inner wall of the adjustment block, and a second drive motor is provided at the top connection end of the second threaded rod.

[0013] Preferably, the electromagnetic coils are provided in two sets, both located in the inner layers of the lower and upper pressure rollers.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The plate rolling machine with a guiding device is equipped with a guiding mechanism. The upper and lower guide rollers guide the plate before it enters the rolling area, ensuring that the plate enters between the upper and lower pressure rollers along a predetermined straight trajectory. This avoids the plate from deviating or tilting during the rolling process. At the same time, by adjusting the distance between the upper and lower guide rollers, it can accommodate plates of different thicknesses, making the guidance more precise.

[0016] The magnetic field generated by the electromagnetic coil in the adjustment mechanism causes the upper and lower pressure rollers to attract the sheet material, increasing the friction and adhesion between the sheet material and the pressure rollers, effectively preventing the sheet material from slipping and shifting during the rolling process.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Example

[0025] like Figure 1-3 As shown, the device includes a body 1, a guide mechanism 2 on the top of the body 1, and adjustment mechanisms 3 on both sides of the body 1. The guide mechanism 2 includes mounting seats 201 installed on both sides of the top of the body 1. The inner wall of the mounting seat 201 is provided with a slider 202. The bottom of the mounting seat 201 is provided with a groove 203. A lower guide wheel 204 is provided on one side of the mounting seat 201. An upper guide wheel 205 is provided on one side of the slider 202. A baffle 206 is provided on one side of the bottom of the slider 202. The guide mechanism 2 also includes a limiting post 207 installed on the inner wall of the mounting seat 201. A first threaded rod 208 is provided on the inner wall of the mounting seat 201. A first drive motor 209 is provided at the connecting end of the first threaded rod 208.

[0026] It should be noted that in this embodiment, the plate is conveyed to the entrance of the plate rolling machine, ready to enter the plate rolling process. At this time, the upper guide wheel 205 and the lower guide wheel 204 are in the initial position. According to the thickness and width of the plate, the first drive motor 209 drives the first threaded rod 208 to rotate. Since the first threaded rod 208 is threadedly connected to the slider 202, and the slider 202 is restricted by the limiting post 207 and can only slide up and down along the limiting post 207, the slider 202 and the upper guide wheel 205 on it move. The distance between the slider 202 and the bottom of the mounting base 201 is adjusted to adjust the distance between the upper guide wheel 205 and the lower guide wheel 204, so that it is slightly larger than the thickness of the plate, so that the plate can enter smoothly. At the same time, the baffle 206 is located in the groove 203, which plays a role in limiting the side of the plate.

[0027] The sheet material passes between the upper guide wheel 205 and the lower guide wheel 204. With the rolling support of the guide wheels, the sheet material can maintain a relatively stable linear motion state when entering the roll area. The rolling friction of the guide wheels is small, which can guide the sheet material forward without causing obvious scratches or damage to the surface of the sheet material.

[0028] like Figure 4 , 5 As shown, the adjustment mechanism 3 includes side plates 301 installed on both sides of the machine body 1, a lower pressure roller 302 is provided on the top of the machine body 1, an upper pressure roller 303 is provided between the side plates 301, and the upper pressure roller 303 is located above the lower pressure roller 302. An adjustment block 304 is slidably connected to the inner wall of the side plate 301. An electromagnetic coil 305 is provided in the inner layer of the upper pressure roller 303. A second threaded rod 306 passes through the inner wall of the adjustment block 304. A second drive motor 307 is provided at the top connection end of the second threaded rod 306.

[0029] It should be noted that in this embodiment, when the sheet material enters the rolling area between the lower pressure roller 302 and the upper pressure roller 303, the second drive motor 307 drives the second threaded rod 306 to rotate, causing the adjusting block 304 to move on the inner wall of the side plate 301, thereby adjusting the gap between the upper pressure roller 303 and the lower pressure roller 302. After adjusting to the appropriate position, the electromagnetic coil 305 inside the upper pressure roller 303 and the lower pressure roller 302 is turned on. The magnetic field generated by the electromagnetic coil 305 will cause the upper pressure roller 303 and the lower pressure roller 302 to generate a certain attraction force on the sheet material, further enhancing the stability of the sheet material during the rolling process, preventing the sheet material from slipping or shifting during the rolling process, and ensuring the accuracy and quality of the rolled sheet.

[0030] Working principle of this utility model:

[0031] Refer to the instruction manual appendix Figure 1-5 The sheet metal is conveyed to the entrance of the plate rolling machine, ready to enter the plate rolling process. At this time, the upper guide wheel 205 and the lower guide wheel 204 are in the initial position. According to the thickness and width of the sheet metal, the first drive motor 209 drives the first threaded rod 208 to rotate. Since the first threaded rod 208 is threadedly connected to the slider 202, and the slider 202 is restricted by the limiting post 207 and can only slide up and down along the limiting post 207, the slider 202 and the upper guide wheel 205 on it move. The distance between the upper guide wheel 205 and the lower guide wheel 204 is adjusted by adjusting the distance between the slider 202 and the bottom of the mounting base 201, so that it is slightly larger than the thickness of the sheet metal, so that the sheet metal can enter smoothly. At the same time, the baffle 206 is located in the groove 203, which plays a role in limiting the side of the sheet metal.

[0032] The sheet material passes between the upper guide wheel 205 and the lower guide wheel 204. With the rolling support of the guide wheels, the sheet material can maintain a relatively stable linear motion state when entering the roll area. The rolling friction of the guide wheels is small, which can guide the sheet material forward without causing obvious scratches or damage to the surface of the sheet material.

[0033] Subsequently, the sheet material enters the rolling area between the lower pressure roller 302 and the upper pressure roller 303. At this time, the second threaded rod 306 is driven to rotate by the second drive motor 307, which drives the adjusting block 304 to move on the inner wall of the side plate 301, thereby adjusting the gap between the upper pressure roller 303 and the lower pressure roller 302. After adjusting to the appropriate position, the electromagnetic coil 305 inside the upper pressure roller 303 and the lower pressure roller 302 is turned on. The magnetic field generated by the electromagnetic coil 305 will cause the upper pressure roller 303 and the lower pressure roller 302 to generate a certain attraction force on the sheet material, further enhancing the stability of the sheet material during the rolling process, preventing the sheet material from slipping or shifting during the rolling process, and ensuring the accuracy and quality of the rolled sheet.
