Description

Technical Field

[0001] The utility model relates to the field of metal material processing and rolling, and particularly relates to a buffer adjustable edge pressing machine without thickness difference. Background Art

[0002] With the continuous improvement of the market's requirements for the processing quality of metal materials, the forming and appearance quality of the material boundary during the finished product processing are becoming increasingly important. Special edge pressing equipment is required to press the material boundary. The current edge pressing equipment includes two edge pressing rollers. The metal material passes through the two edge pressing rollers, and the two edge pressing rollers press the material boundary, so as to beautify the edge of the material and prevent the edge of the material from having sharp edges.

[0003] However, the distance between the two edge pressing rollers on the current edge pressing equipment is not adjustable. The two edge pressing rollers can only press metal materials with a specific thickness, and the adaptability of the edge pressing equipment to the thickness of the metal material is poor. Metal materials with different thicknesses need to be edge pressed on different edge pressing equipment, and the operation is relatively troublesome. Since different edge pressing equipment needs to be set, the equipment cost is high.

[0004] Even if the current edge pressing equipment can press metal materials with different thicknesses, every time when pressing metal materials with different thicknesses, the distance between the two edge pressing rollers needs to be manually adjusted, and the operation is also relatively troublesome. Summary of the Utility Model

[0005] The utility model aims to provide a buffer adjustable edge pressing machine without thickness difference, so as to realize edge pressing of metal materials with different thicknesses, reduce manual adjustment operations, and improve the use convenience.

[0006] To achieve the above purpose, the utility model adopts the following technical scheme: a buffer adjustable edge pressing machine without thickness difference, which includes a frame and two edge pressing rollers. The axes of the two edge pressing rollers are arranged in parallel, the two edge pressing rollers are arranged oppositely, and the distance between the two edge pressing rollers can be automatically adjusted; an elastic device for making the two edge pressing rollers approach each other is arranged on the frame.

[0007] The principle and advantages of this solution are as follows: Since the distance between the two blank holding rollers in this solution can be automatically adjusted, the distance between the two blank holding rollers is not fixed. When metal materials of different thicknesses pass through the two blank holding rollers, the distance between the two blank holding rollers is adjusted according to the thickness of the metal material. The elastic device is used to make the two blank holding rollers approach each other and exert a squeezing force on the metal material. In this way, when the metal material passes between the two blank holding rollers, the blank holding rollers squeeze the edge of the metal material under the elastic force of the elastic device. When the thickness of the metal material changes, since the distance between the two blank holding rollers is not fixed, the distance between the two blank holding rollers automatically adjusts following the thickness of the metal material, so that blank holding can be performed on metal materials of different thicknesses. Metal materials of different thicknesses can all pass through this blank holding machine for blank holding without discrimination among metal materials of different thicknesses, reducing the operation of manual adjustment, making the operation simple and convenient. At the same time, there is no need for multiple blank holding machines of different specifications, saving equipment costs and space occupancy.

[0008] Preferably, as an improvement, the elastic device includes an elastic member, and the two blank holding rollers approach each other under the elastic force of the elastic member.

[0009] Preferably, as an improvement, support shafts are coaxially connected to both of the two blank holding rollers, and the elastic force of the elastic member acts on the support shafts. Thus, the support shafts are used to support the blank holding rollers. By applying the elastic force to the support shafts through the elastic member, the two blank holding rollers are made to have a force approaching each other.

[0010] Preferably, as an improvement, the elastic member is a tension spring, and the tension spring is connected between the two support shafts; or,

[0011] The elastic member is a compression spring, and the number of compression springs is at least two, and the two compression springs are respectively pressed on the opposite sides of the two support shafts.

[0012] Preferably, as an improvement, rod holes are provided on both of the two support shafts, the two rod holes are opposite to each other, a vertical rod passes through the two rod holes, and limiting members are connected to both ends of the vertical rod. The limiting members at both ends of the vertical rod are respectively used to abut against the opposite sides of the two support shafts.

[0013] Thus, the vertical rod plays a role in guiding and limiting the movement of the support shafts, making the movement of the two blank holding rollers more stable when metal materials of different thicknesses pass between the two blank holding rollers.

[0014] At the same time, by providing two limiting members on the vertical rod, on the one hand, it can prevent the vertical rod from slipping off the rod holes on the support shafts, and on the other hand, the two limiting members are respectively used to abut against the opposite sides of the two support shafts, thereby limiting the maximum distance between the two support shafts.

[0015] Preferably, as an improvement, the position of the limiting member on the vertical rod is adjustable.

[0016] Thus, by adjusting the position of the limiting member on the vertical rod, the maximum distance between the two support shafts can be changed, so that the maximum thickness value of the metal material that can pass between the two pressure rollers can be changed.

[0017] Preferably, as an improvement, the limiting member is a nut, a screw, a bolt or a pin.

[0018] The limiting member can be selected with different structures, and any structure that can limit the abutment of the two support shafts and prevent the vertical rod from detaching from the support shaft is acceptable.

[0019] Preferably, as an improvement, a bracket for connecting with the support shaft is provided on the frame, and the connecting part of the bracket and the support shaft can undergo elastic deformation.

[0020] Thus, by the elastic deformation of the connecting part of the bracket and the support shaft, the distance between the two support shafts can be adjusted, and the distance between the two pressure rollers is adjustable.

[0021] Preferably, as an improvement, a support block is provided on the frame, and a vertical sliding groove is provided on the support block, and the end of the support shaft slides in the sliding groove.

[0022] Thus, by the end of the support shaft sliding in the sliding groove of the support block, the distance between the two support shafts can be adjusted, and the distance between the two pressure rollers is adjustable.

[0023] Preferably, as an improvement, the pressure roller is a hollow roller.

[0024] Thus, the pressure roller in the present application is a hollow roller, and the hollow structure design can reduce its weight, making its own weight lighter, easier to rotate, and more labor-saving to rotate. Description of the Drawings

[0026] Figure 2 It is a schematic structural diagram of the press for Embodiment 2. Detailed Description of the Invention

[0027] The following is a further detailed description through specific embodiments:

[0028] The reference numerals in the accompanying drawings of the specification include: frame 1, mounting hole 2, first pressure roller 3, second pressure roller 4, first bearing 5, second bearing 6, third bearing 7, fourth bearing 8, first connecting member 9, second connecting member 10, first support shaft 11, second support shaft 12, limiting member 13, vertical rod 14, tension spring 15, bracket 16, separation angle 17, support block 18.

[0029] Example 1

[0030] Basically as shown in the attached Figure 1 figure: This example discloses a buffer adjustable blank holder without thickness difference, including a frame 1 and two blank holders. The two blank holders are respectively the first blank holder 3 and the second blank holder 4. The first blank holder 3 is located above the second blank holder 4, and the axes of the first blank holder 3 and the second blank holder 4 are parallel.

[0031] In this example, the first blank holder 3 and the second blank holder 4 have the same shape and structure, and both the first blank holder 3 and the second blank holder 4 are hollow structures; the circumferential sides of the first blank holder 3 and the second blank holder 4 are both arc-shaped. The diameter of the blank holder gradually decreases from the middle of the blank holder to the end of the blank holder. Figure 1 In the middle, the middle parts of the first blank holder 3 and the second blank holder 4 are in contact with each other or there is a gap for the metal material (such as an aluminum plate) to pass through between the middle parts of the first blank holder 3 and the second blank holder 4. There is a gap between the ends of the two blank holders to form a separation angle 17.

[0032] In this example, bearings and support shafts are installed inside both of the two blank holders; the outer ring of the bearing is connected to the inner wall of the blank holder, and the support shaft is connected to the inner ring of the bearing. Specifically, the first blank holder 3 is internally provided with a first bearing 5 and a second bearing 6. The first bearing 5 and the second bearing 6 are respectively located at both ends of the first blank holder 3. The outer rings of the first bearing 5 and the second bearing 6 are both connected to the inner wall of the first blank holder 3. The connection method can be interference connection, or connection by pins or keys. A first support shaft 11 is connected between the inner rings of the first bearing 5 and the second bearing 6. The connection method can be interference connection, or connection by pins or keys. The second blank holder 4 is internally provided with a third bearing 7 and a fourth bearing 8. A second support shaft 12 is connected between the inner rings of the third bearing 7 and the fourth bearing 8. The connection method of the bearings inside the second blank holder 4 and the setting method of the support shaft are the same as those of the bearings inside the first blank holder 3. Therefore, the connection method of the bearings inside the second blank holder 4 and the connection setting method of the second support shaft 12 will not be elaborated here.

[0033] In the frame 1 of this embodiment, there are mounting holes 2, which are used for fixing bolts to pass through for fixation, so as to facilitate the fixation of the frame 1. Two brackets 16 are fixedly arranged (such as welded) on the frame 1. The right ends of the first support shaft 11 and the second support shaft 12 are respectively connected to the two brackets 16 (such as welded or integrally connected). In this embodiment, the connection parts between the right ends of the first support shaft 11 and the bracket 16 and the connection parts between the right ends of the second support shaft 12 and the bracket 16 can both undergo elastic deformation (similar to the torsion beam of an automobile that can undergo elastic deformation), so that the vertical distance between the two support shafts can be adjusted.

[0034] On the frame 1, there is an elastic device for making the first crimping roller 3 and the second crimping roller 4 approach each other. The elastic device includes an elastic member, and the two crimping rollers approach each other under the elastic force of the elastic member.

[0035] For the elastic member, a tension spring 15 is selected in this embodiment. The tension spring 15 is connected between the first support shaft 11 and the second support shaft 12. The connection mode between the end of the tension spring 15 and the corresponding support shaft can specifically be welding, hooking, or fixing by screws. Thus, under the tensile force of the tension spring 15, the first support shaft 11 and the second support shaft 12 make the two crimping rollers approach each other. When the metal material passes between the two crimping rollers, the two crimping rollers perform edge crimping on the metal material under the elastic force of the tension spring 15.

[0036] In addition, the maximum distance between the first crimping roller 3 and the second crimping roller 4 in this embodiment is adjustable, that is, the maximum thickness of the metal material allowed to pass through is adjustable. The specific adjustment method is as follows: Vertical rod holes are provided on both the first support shaft 11 and the second support shaft 12. A vertical rod 14 passes through the rod hole of the first support shaft 11 and the rod hole of the second support shaft 12. Limit members 13 are threadedly connected to the top and bottom ends of the vertical rod 14. The limit members 13 can specifically be bolts, screws (when using screws or bolts, threaded holes are provided at the ends of the vertical rod 14), or nuts. By rotating the limit members 13, the adjustment of the position of the limit members 13 is realized. Nuts are preferably used in this embodiment. The limit member 13 can also be a pin. By laterally inserting the pin on the vertical rod 14, the mutually facing sides of the two support shafts are limited. At this time, a plurality of horizontal jack holes are provided on the vertical rod 14. By inserting the pin into different jack holes, the adjustment of the position of the pin is realized. In this embodiment, the limit members 13 at both ends of the vertical rod 14 can limit the maximum distance between the first support shaft 11 and the second support shaft 12, so that the crimping machine can only crimp metal materials within the set maximum thickness. By arranging the limit members 13 on the vertical rod 14 in this embodiment, on the one hand, it can prevent the vertical rod 14 from detaching from the two support shafts, and on the other hand, the limit members 13 can abut against the mutually facing sides of the two support shafts, thereby limiting the maximum distance between the two support shafts.

[0037] Thus, when the metal material passes between the two blank holding rollers, the two support shafts have a force to approach each other under the action of the tension spring 15. The two support shafts cause the two blank holding rollers to squeeze the edge of the metal material under the pulling force of the tension spring 15, thereby realizing blank holding. When metal materials of different thicknesses pass between the two blank holding rollers, the distance between the two blank holding rollers can be automatically adjusted. When the metal material with a larger thickness passes between the two blank holding rollers, the first blank holding roller 3 and the second blank holding roller 4 move away from each other, and the two support shafts move away from each other (at this time, neither of the two support shafts abuts against the limiting member 13), and the tension spring 15 is stretched. When the metal material with a smaller thickness passes between the two blank holding rollers, the first blank holding roller 3 and the second blank holding roller 4 move closer to each other under the pulling force of the tension spring 15, so as to perform blank holding on the metal material with a smaller thickness. Therefore, the blank holder in this embodiment can perform blank holding on metal materials of different thicknesses.

[0038] Although the blank holder in this embodiment can perform blank holding on metal materials of different thicknesses, when the two support shafts respectively abut against the two limiting members 13, this is the maximum distance between the two support shafts at this time, and the distance between the two blank holding rollers is the largest, then it is impossible to perform blank holding on a thicker metal material anymore.

[0039] If the thickness of the metal material exceeds the maximum distance between the two blank holding rollers, then the distance between the two limiting members 13 needs to be adjusted to be able to adapt to a thicker metal material. For example, the thickness of the metal material allowed to pass through the two blank holding rollers in the previous batch does not exceed 1 mm. When the thickness of the metal material to be passed becomes 3 mm, then the upper limiting member 13 needs to be adjusted upward or the lower limiting member 13 needs to be adjusted downward (the upper limiting member 13 and the lower limiting member 13 can be adjusted simultaneously or only one of them can be adjusted). In this way, the distance between the two limiting members 13 becomes larger, and the maximum distance between the first support shaft 11 and the second support shaft 12 can become larger. When a thicker metal material passes between the two blank holding rollers, the distance between the first support shaft 11 and the second support shaft 12 can become larger, so that the two blank holding rollers can perform blank holding on a thicker metal material and enable a thicker metal material to pass through.

[0040] Of course, the limit member 13 can also be adjusted to reduce the maximum distance between the two crimping rollers. For example, the thickness of the metal material crimped in the previous batch is 0.5 - 1 mm. When the average thickness of the metal material in the next batch is less than 0.5 mm, a relatively large gap between the two crimping rollers is not required. At this time, the upper limit member 13 needs to be adjusted downward or the lower limit member 13 needs to be adjusted upward (the upper limit member 13 and the lower limit member 13 can be adjusted simultaneously or only one of them can be adjusted). In this way, the distance between the two limit members 13 becomes smaller, and the two limit members 13 respectively limit the two support shafts, and the maximum distance between the first support shaft 11 and the second support shaft 12 becomes smaller, so that the two crimping rollers can adapt to the metal material with a thinner thickness for crimping to ensure the crimping force and the crimping effect.

[0041] Thus, through the crimping machine in this embodiment, metal materials with different thicknesses can be crimped. When the metal material passes between the two crimping rollers, the two crimping rollers move away from each other, and the tension spring 15 can also buffer the impact of the two support shafts on the limit member 13.

[0042] In addition, the roller bodies of the two crimping rollers in this embodiment are arc-shaped. In this way, the metal material (such as an aluminum plate) passes between the first crimping roller 3 and the second crimping roller 4, and the edge of the metal material passes between the middle of the circumferential side surface of the first crimping roller 3 and the middle of the circumferential side surface of the second crimping roller 4. The first crimping roller 3 and the second crimping roller 4 rotate, and the middle of the circumferential side surface of the first crimping roller 3 and the middle of the circumferential side surface of the second crimping roller 4 squeeze the edge of the metal material. The gap between other parts of the two crimping rollers except the middle part is relatively large, that is, the separation angle 17 does not contact and squeeze other parts of the metal material, so as to realize the precise extrusion of the edge of the metal material and not squeeze the parts other than the edge part of the metal material, precisely control the effective contact area, and ensure the quality and precision of the processed material.

[0043] When the two crimping rollers in this embodiment squeeze the metal edge, the separation angle 17 formed by the two crimping rollers can accommodate foreign objects, prevent foreign objects and dirt from being squeezed onto the metal material to cause damage, and ensure the cleanliness of the metal material surface.

[0044] Of course, in other embodiments, the crimping roller can also adopt a common flat roller structure (the surface of the roller body is not arc-shaped). In other embodiments, the crimping roller can also be a solid structure.

[0045] In addition, in other embodiments, during the rotation of the first edge pressing roller 3 and the second edge pressing roller 4, to prevent the first edge pressing roller 3 and the second edge pressing roller 4 from disengaging from the left ends of the first support shaft 11 and the second support shaft 12 respectively, end caps may be covered on the left ends of the first edge pressing roller 3 and the second edge pressing roller 4, and the end caps are connected to the corresponding support shafts. Specifically, for example, the end cap covers the left end of the edge pressing roller, and the end cap is fixedly connected to the edge pressing roller (here, the fixed connection means that the end cap and the edge pressing roller cannot rotate relative to each other. For example, the left end of the end cap and the edge pressing roller are connected by bolts), and the end cap is rotatably connected to the support shaft (a shaft hole is provided on the end cap, and the corresponding support shaft passes through the shaft hole of the end cap, and the end cap can rotate on the corresponding support shaft). A connecting member is fixed to the end of the corresponding support shaft (a first connecting member 9 is fixed to the left end of the first support shaft 11, and a second connecting member 10 is fixed to the left end of the second support shaft 12). The connecting member may specifically be a pin, a bolt or a screw, and the connecting member abuts against the outer wall of the end cap. Thus, during the rotation of the first edge pressing roller 3 and the second edge pressing roller 4, the end cap on the edge pressing roller rotates on the corresponding support shaft, and the connecting member laterally limits the end cap, and the end cap cannot move to the left, and the connecting member can prevent the edge pressing roller from moving to the left and disengaging from the corresponding support shaft.

[0046] Alternatively, in other embodiments, the connection setting manner of the end cap may also be: the end cap is rotatably connected to the edge pressing roller (for example, the end cap only abuts against the left end of the edge pressing roller without being fixed, and the edge pressing roller and the end cap can rotate relative to each other), and the end cap is fixedly connected to the support shaft. Here, the fixed connection means that the end cap and the support shaft are fixed together and the end cap cannot rotate. For example, they are fixedly connected by a connecting member. The connecting member (a first connecting member 9 is fixed to the left end of the first support shaft 11, and a second connecting member 10 is fixed to the left end of the second support shaft 12) may specifically be a bolt or a screw. By tightening the connecting member, the end cap is fixed to the left end of the corresponding support shaft. Thus, during the rotation of the first edge pressing roller 3 and the second edge pressing roller 4, the end of the edge pressing roller rotates relative to the end cap, and the end cap prevents the edge pressing roller from disengaging from the corresponding support shaft to the left.

[0047] Alternatively, in other embodiments, the end cap is rotatably connected to the edge pressing roller, and the end cap is rotatably connected to the support shaft. At this time, the end cap is installed on the corresponding support shaft through a connecting member, the connecting member is not tightened, the end cap can rotate but cannot move laterally, and the end cap and the edge pressing roller are not fixedly connected, and the end cap and the edge pressing roller can rotate relative to each other. At this time, during the rotation of the edge pressing roller, the end cap can prevent the edge pressing roller from moving to the left and disengaging from the corresponding support shaft.

[0048] Of course, the connecting member is not limited to the above description. Any component that can fix the end cap and the support shaft and prevent the end cap from disengaging from the support shaft can be regarded as a connecting member.

[0049] Since Figure 1In it, the left ends of the first support shaft 11 and the second support shaft 12 are both free ends, and there is no structure at the left ends of the first support shaft 11 and the second support shaft 12 to block the crimping roller (the right ends of the first support shaft 11 and the second support shaft 12 are blocked by the frame 1 when the crimping roller moves to the right). Therefore, it is preferred to limit the crimping roller at the left ends of the first support shaft 11 and the second support shaft 12 in the above manner and structure to prevent the crimping roller from moving leftward and disengaging from the corresponding support shaft. Of course, in other embodiments, an end cover may also be provided at the right end of the crimping roller, and a limit pin may be installed on the two support shafts (the limit pin is inserted radially on the corresponding support shaft, and the limit pin may be replaced by other limit structures in other embodiments, such as a limit rod, a screw, etc.). The limit pin is located on the right side of the end cover at the right end of the crimping roller, so as to limit the end cover at the right end and prevent the crimping roller from moving to the right. In this way, the crimping roller can be stably limited by the two end covers on the left and right and cannot move left and right.

[0050] Embodiment 2

[0051] The difference between this embodiment and Embodiment 1 is that the right ends of the first support shaft 11 and the second support shaft 12 can also be slidably connected to the frame 1. At this time, the bracket 16 is omitted. As shown in combination with Figure 2 shown, a support block 18 is welded to the left side of the frame 1. A vertical chute is provided on the left side surface of the support block 18. The top view shape of the chute is T-shaped. T-shaped sliders are provided at the right ends of the first support shaft 11 and the second support shaft 12. The sliders are located in the chute and can slide vertically. In this way, neither the first support shaft 11 nor the second support shaft 12 is fixedly connected to the frame 1. When materials of different thicknesses pass through the two crimping rollers, the first support shaft 11 and the second support shaft 12 can move vertically, so as to be suitable for crimping materials of different thicknesses. The vertical position adjustment of the first support shaft 11 and the second support shaft 12 is smoother.

[0052] The above are only the embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics known to the public are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicability of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
