Description
Technical Field
[0001] The utility model belongs to the technical field of precious metal ultra-thin material processing, and particularly relates to a stable feeding auxiliary device for ultra-thin metal strip cooperating with a straightening machine. Background Art
[0002] Before stamping ultra-thin alloy strip, there is a straightening process completed by a straightening machine. In the prior art, most of the feeding ports of the straightening machine adopt roller-assisted feeding, and this method has many drawbacks: First, when feeding ultra-thin alloy strip, it is prone to left and right offset and torsion due to the lack of a limiting structure, and even the straightening machine cannot work properly; in addition, the surface flatness of different batches of ultra-thin alloy strip is different. If the surface is relatively uneven, the strip is prone to form large up and down undulations on the roller during feeding, and even fly out of the roller, resulting in strip damage or even inability to feed normally; furthermore, due to the left and right offset at the feeding end, it is very difficult for the straightening machine to straighten and discharge according to the preset direction, which will not only cause deformation or unevenness on both sides of the strip, but also affect the operation in the stamping stage and the accuracy of the product after stamping; based on the above drawbacks, it is necessary to develop a feeding auxiliary device that cooperates with the straightening machine and can limit the left and right positions of ultra-thin metal material and moderately suppress the undulations of the strip during feeding, so as to assist the strip to stably enter the straightening machine and meet the working requirements of the straightening machine and subsequent stamping. Content of the Utility Model
[0003] To overcome the above drawbacks, the purpose of the utility model is to provide a stable feeding auxiliary device for ultra-thin metal strip cooperating with a straightening machine.
[0004] The object of the present utility model is achieved as follows. The ultra-thin metal strip stable feeding auxiliary device cooperating with the straightening machine includes a base, a pressing plate type channel, pressing bars, and limiting sliders. The base is of a cuboid structure. A through groove with an inverted T-shaped cross-section is arranged in the base along the length direction, and the through groove extends upward to form a groove-shaped opening on the upper surface of the base. The long side of the base is vertically arranged corresponding to the feeding direction at the feeding port of the straightening machine. One pressing bar is arranged on each side of the groove-shaped opening along the length direction of the base. Both ends of each pressing bar are slidably sleeved with adjusting screws arranged on the base. An adjusting nut I is screwed on the adjusting screw above the pressing bar, and a spring is sleeved on the adjusting screw below the pressing bar. The pressing plate type channel is composed of an active pressing plate and a lower pressing plate which are superposed with suitable dimensions. The space between the active pressing plate and the lower pressing plate is the feeding channel for the strip. The active pressing plate and the lower pressing plate are cuboid plates, and the long sides are perpendicular to the pressing bars and are arranged between the pressing bars and the base. The active pressing plate is clamped corresponding to the side of the pressing bar by the convex strip on the back side of the strip entering end and can float up and down between the pressing bar and the base along with the strip. The lower pressing plate is fixed on the base or is clamped corresponding to the side of the base by the convex strip on the back side of the strip entering end of the lower pressing plate. The limiting slider is a cuboid block with a convex block below, and a vertical through hole is arranged through the convex block. Two limiting sliders are arranged on both sides of the pressing plate type channel along the length direction parallel to the long side of the pressing plate and are located below the pressing bar. The convex block is adapted to the groove-shaped opening and can slide in cooperation. The inverted T-shaped screw arranged in the through groove passes upward through the through hole and is screwed with an adjusting nut II.
[0005] The technical effects of the present utility model:
[0006] (1) The core structure of the device described in this application is the pressing plate type channel. The space between the active pressing plate and the lower pressing plate in the channel is the feeding channel for the ultra-thin metal strip. The pressing bar limits the active pressing plate and leaves a certain margin for the active pressing plate to fluctuate with the surface shape of the strip, realizing the pressing of the strip while reducing the reaction impact of the active pressing plate on the strip, thereby reasonably controlling the vertical movement of the strip. Based on this, when the strip advances, the lateral offset acting force is significantly reduced, and when the side encounters the limiting slider, the edge of the strip will not be distorted or deformed, thus realizing the continuous and stable feeding of the strip.
[0007] (2) Since the strip has a certain elasticity and rigidity strength, through the effective control of the movement state of the strip at the feeding end of the straightening machine, it not only meets the requirements of the straightening operation in the straightening machine, but also can synchronously affect the movement state of the strip when the straightening machine discharges, thereby reducing the difficulty of the feeding operation in the stamping stage.
[0008] After application, it is found that the device described in the present application can not only avoid the offset and deformation of the strip during the feeding of the straightening machine by reasonably controlling the movement state of the strip, but also synchronously improve the feeding and discharging effects and working efficiency during the straightening stage and the stamping stage. In particular, the stamping efficiency and product quality of the straightened strip can be increased to 2-3 times that of the past. At the same time, the device described in the present application also has the advantages of simple structure, convenient operation during application, and a wide adaptability range for the surface state of the strip.

[0013] The present utility model will be further described below in conjunction with the drawings, but it is not limited to the present utility model in any way. Any transformation or replacement based on the teachings of the present utility model falls within the protection scope of the present utility model.
[0014] As shown in the figure, the ultra-thin metal strip stable feeding auxiliary device cooperating with the straightening machine includes a base 10, a pressing plate type channel, a pressing strip 7, and a limiting slider 2; the base 10 is of a cuboid structure, and a through groove with an inverted T-shaped cross-section is arranged in the base 10 along the length direction, and the through groove extends upward to form a groove-shaped opening on the upper surface of the base 10. The long side of the base 10 is vertically arranged corresponding to the feeding direction at the feeding port of the straightening machine; on both sides of the groove-shaped opening, one pressing strip 7 is arranged along the length direction of the base 10. Both ends of each pressing strip 7 are slidably sleeved with adjusting screws 9 arranged on the base 10. An adjusting nut I is screwed on the adjusting screw 9 above the pressing strip 7, and a spring 8 is sleeved on the adjusting screw 9 below the pressing strip 7; the pressing plate type channel is composed of an active pressing plate 1a and a lower pressing plate 1b with suitable sizes stacked up and down. The space between the active pressing plate 1a and the lower pressing plate 1b is the strip entering channel. The active pressing plate 1a and the lower pressing plate 1b are cuboid plates, and the long sides are perpendicular to the pressing strip 7 and are arranged between the pressing strip 7 and the base 10. The active pressing plate 1a is clamped and corresponding to the side of the pressing strip 7 by the convex strip on the back side of the strip entering end and can float up and down between the pressing strip 7 and the base 10 along with the strip. The lower pressing plate 1b is fixed on the base 10 or is clamped and corresponding to the side of the base 10 by the convex strip on the back side of the strip entering end of the lower pressing plate 1b; the limiting slider 2 is a cuboid block with a convex block below, and a vertical through hole is arranged through the convex block. Two limiting sliders 2 are arranged on both sides of the pressing plate type channel along the length direction parallel to the long side of the pressing plate and are located below the pressing strip 7. The convex block is adapted to the groove-shaped opening and can be slidably mated. The inverted T-shaped screw 4 arranged in the through groove passes upward through the through hole and is screwed with an adjusting nut II.
[0015] The widths of the active pressing plate 1a and the lower pressing plate 1b are adapted to the width of the ultra-thin metal strip material.
[0016] The active pressing plate 1a and / or the lower pressing plate 1b is a pressing plate made of acrylic material. Based on the fact that the acrylic material is light in weight and easy to form a smooth surface, it is suitable for making the pressing plate type channel.
[0017] The end of the limiting slider 2 at the strip entering end is flush with the side of the base 10, and the other end extends into the feeding port of the straightening machine; with such a setting, the left-right limiting length of the ultra-thin metal strip in the feeding port is increased, which is more beneficial to controlling the deviation of the ultra-thin metal strip entering the straightening machine.
[0018] The distance between the pressing strips 7 on both sides of the groove-shaped opening is not less than the width of the groove-shaped opening; with such a setting, it is avoided that the rotation adjustment of the adjusting nut II is affected due to too small a width.
[0019] The adjusting nut I is an anti-slip nut 6; the adjusting nut II is a butterfly nut 5.
[0020] A sleeve 3 is sleeved on the inverted T-shaped screw rod 4 between the adjusting nut II and the limiting slider 2; adding the sleeve 3 can increase the height of the adjusting nut II, making it more convenient to adjust.
[0021] A countersunk hole 11 for connecting with the feeding port of the straightening machine is arranged at the bottom of the through groove, which is convenient for the disassembly and assembly of the device on the straightening machine.
[0022] The working principle of the utility model:
[0023] The core structure of the device described in this application is that the pressing plate type channel is composed of an active pressing plate 1a and a lower pressing plate 1b stacked up and down. The feeding channel for the ultra-thin metal strip is between the active pressing plate 1a and the lower pressing plate 1b; the active pressing plate 1a and the lower pressing plate 1b are stacked and corresponding, and the convex strip on the back side is clamped corresponding to the side of the pressing strip 7, so that the active pressing plate 1a is in an active state. When the strip passes through, the lower pressing plate 1b basically remains stationary, while the active pressing plate 1a can float up and down with the surface shape of the strip; since whether the lower pressing plate 1b is fixed has little impact on the feeding, therefore, it is feasible to fix the lower pressing plate 1b on the base 10; to adapt to different specifications of strips, it may be necessary to select active pressing plates 1a and lower pressing plates 1b with different widths. Therefore, it is more convenient to replace the lower pressing plate 1b by clamping the convex strip on the back side corresponding to the side of the base 10.
[0024] The adjusting screw 9, spring 8, and adjusting nut I on the base 10 make the distance between the pressing strip 7 and the base 10 adjustable. When the strip is fed through the pressing plate type channel, the active pressing plate 1a forms a pressing force above the strip to prevent the strip from undulating or jumping excessively during feeding; at the same time, since the surface flatness of different batches of strips is different, if the distance between the active pressing plate 1a and the lower pressing plate 1b is fixed, the distance needs to be adjusted according to the highest point on the surface of each batch of strips, otherwise it will cause serious wear to the strip; however, even if the distance is greater than the highest point on the surface of the strip, the strip will still undulate and jump when passing through due to the uneven surface, and it is difficult to avoid wear on the surface of the strip; for this reason, in the device described in this application, the distance between the active pressing plate 1a and the lower pressing plate 1b of the pressing plate type channel is adjustable and the active pressing plate 1a can float up and down with the surface shape of the strip; with such a setting, there is no need to adjust the pressing plate distance according to the surface shape of the strip every time. As long as an appropriate margin is left for the vertical movement of the active pressing plate 1a, it can adapt to various surface flatness conditions. Moreover, while the active pressing plate 1a forms a pressing force on the strip, it also reduces the impact of the reaction force of the active pressing plate 1a on the surface of the strip. Cooperating with the limiting sliders 2 on both sides of the pressing plate type channel, it avoids the deviation of the strip caused by excessive undulation; since the pressing plate type channel reasonably controls the vertical movement form of the strip, the lateral offset acting force when the strip passes through is significantly reduced, and the strip will not be distorted or deformed at the edge due to collision with the limiting slider 2, thus realizing continuous and stable feeding of the strip.
[0025] During the conventional processing process, after the ultra-thin alloy strip is released from the reel, it passes through a straightening machine and a stamping machine in sequence, and the strip is continuous during this process; due to the certain elasticity and rigidity strength of the strip, by effectively controlling the movement state of the strip at the feeding end of the straightening machine, it can synchronously affect the movement state of the strip when it exits the straightening machine, thereby reducing the difficulty of the feeding operation in the stamping stage.
[0026] The application method of the present utility model:
[0027] Select the movable pressing plate 1a and the lower pressing plate 1b with appropriate widths according to the width of the strip, and stack and arrange them between the pressing strip 7 and the base 10. Adjust the distance between the two side limiting sliders 2 and the pressing plate channel to complete the assembly of the device and set it at the feeding port of the straightening machine; then, pass the strip through between the movable pressing plate 1a and the lower pressing plate 1b, and according to the flatness of the strip, rotate and adjust the nut I to obtain an appropriate distance between the base 10 and the pressing strip 7 (it can be based on the condition that the convex strip of the movable pressing plate 1a does not disengage from the side of the pressing strip 7 when the movable pressing plate 1a is at the lowest position, or it can be slightly higher than the highest point of the strip protrusion according to the flatness of the strip), and then the feeding operation can be carried out.
[0028] Example 1
[0029] The ultra-thin metal material to be straightened is an AgCu alloy, a strip material with a thickness of 0.5 mm and a width of 20 mm; select the movable pressing plate 1a and the lower pressing plate 1b with a width of 20 mm, and adjust the distance between the limiting sliders 2 to be slightly larger than the widths of the movable pressing plate 1a and the lower pressing plate 1b to avoid affecting the up and down floating of the movable pressing plate 1a, and at the same time select an appropriate distance between the base 10 and the pressing strip 7; after the device is assembled and installed in place, pass one end of the AgCu alloy ultra-thin strip through between the movable pressing plate 1a and the lower pressing plate 1b, and then the feeding can be carried out; through the ultra-thin metal strip stable feeding auxiliary device, it can ensure the smooth progress of the straightening feeding and straightening operation, and the strip will not appear situations such as strip twisting and deformation.
[0030] Example 2: The ultra-thin metal material to be straightened is an AgCuNi alloy, an AgCuGeCo alloy, an AgCuGa alloy or an AgCu alloy. Select the movable pressing plate 1a and the lower pressing plate 1b with appropriate widths according to the width, adjust the distance between the limiting sliders 2, select an appropriate distance between the base 10 and the pressing strip 7, and pass one end of the strip through between the movable pressing plate 1a and the lower pressing plate 1b, and then the feeding can be carried out; by implementing the feeding of the strips with the above different alloy compositions through the device, it can ensure the smooth progress of the straightening feeding and straightening operation, and the strip will not appear situations such as strip twisting and deformation.
[0031] Comparative example: The ultra-thin metal material to be corrected is the same as that in Example 1, and the roller-assisted feeding in the prior art is adopted; due to the lack of pressing and limiting of the strip, the movement state of the strip is not easy to control when passing through the freely rotatable roller, and the strip will be distorted and deformed at both sides. When the distortion is serious, the entire strip will even shift, making continuous feeding impossible and only allowing restarting after stopping for calibration.
[0032] It can be seen that, compared with the traditional roller-assisted feeding, the device described in the present application can ensure the stable and continuous feeding of the strip. It not only avoids problems such as strip distortion, deformation, and offset during the feeding process, but also synchronously affects the strip running state during the discharging of the straightening machine and the feeding of the stamping machine by controlling the movement state of the strip at the feeding end, which is very beneficial for improving the feeding effect and efficiency in the straightening and stamping stages of the ultra-thin metal strip and improving the final product quality.
