A bending upper die clamping device capable of vertical quick disassembly and assembly

Abstract

The utility model discloses a bending upper mold clamping device capable of vertical quick disassembly and assembly, wherein the upper mold is vertically clamped at the upper mold installation area on the fixed block by a slider, and is pressed and fixed by a clamping plate. When the clamping plate approaches one side of the fixed block, the slider will be driven upward. Since the slider is used to vertically install and disassemble the upper mold body, and an anti-falling surface is provided on the slider, the upper mold body will be driven upward, so that it can finally be moved upward to the installation reference surface, and the upper mold body can also be pressed and fixed laterally. When the clamping plate is away from the fixed block, the slider will move downward relative to the clamping plate together with the upper mold body, and the upper mold body will be lowered vertically, but it will not fall, because the slider is provided with an anti-falling surface to prevent it from falling due to gravity.

Description

Technical Field

[0001] The utility model belongs to the technical field of quick clamping of bending upper dies, in particular to a clamping device for a bending upper die which can be quickly disassembled and assembled vertically. Background Art

[0002] In the workpiece bending process, a bending upper die and a bending lower die are usually required. The bending upper die has an upper die clamping part and an upper die cutter head. The bending lower die is V-shaped. The workpiece is placed between the bending upper die and the bending lower die. The upper die clamping part is clamped on the bending machine. The upper die cutter head applies force to the surface of the workpiece to bend the workpiece.

[0003] Most of the existing upper die clamping structures are side pressure structures, such as CN201394597Y, which requires manual installation of the bending upper die on the installation reference surface and then clamping and fixing it. The operation is complicated and it is easy to fail to accurately install it on the installation reference surface during operation. Another example is CN102626753A, which can complete vertical installation but cannot complete vertical disassembly. It is not applicable to some scenes with limited horizontal installation and disassembly space. Summary of the invention

[0004] Technical issues solved:

[0005] The invention solves the problem that the existing bending upper die clamping structure cannot be quickly disassembled and assembled in the scenario where the lateral disassembly and assembly space is limited.

[0006] In order to solve the above technical problems, the inventors have obtained the technical solution of the utility model through practice and summary. The utility model adopts the following technical solution:

[0007] A bending upper die clamping device capable of vertical quick disassembly and assembly, comprising a fixed block, a clamping plate, a sliding block and an action retaining member;

[0008] An upper mold body installation area is provided at the bottom of the fixed block;

[0009] The clamping plate is slidably arranged relative to the fixed block and the distance between the two is adjustable. The clamping plate is provided with an oblique guide groove and a bottom waist-shaped hole connected with the oblique guide groove;

[0010] The slider is slidably matched with the inclined guide groove, and the slider is used to prevent the upper mold body from falling under the action of gravity, and the upper mold body can be actively separated from the slider vertically;

[0011] The action retaining piece is inserted into the waist-shaped hole at the bottom and slidably cooperates with the sliding block.

[0012] Preferably, the oblique guide groove is arranged obliquely upward, and is located at the bottom of one side of the clamping plate close to the fixing block.

[0013] Preferably, the angle between the inclined guide groove and the horizontal plane is 10-89°.

[0014] Preferably, the slider is provided with an anti-falling surface and a pressing surface, the anti-falling surface is provided at the bottom of the slider and extends outward horizontally, and the pressing surface is provided on a side of the slider opposite to the upper mold body;

[0015] An upper contact plate is also provided on the sliding block. The upper contact plate is located on the top of the pressing surface and extends outward at least twice the width of the anti-falling surface.

[0016] Preferably, the lower surface of the oblique guide groove is provided with a plurality of step structures arranged continuously;

[0017] A sliding surface adapted to the step structure is arranged on one side of the lower surface of the sliding block relative to the inclined guide groove.

[0018] Preferably, it also includes a driving body, which is installed on the fixing block and is used to drive the clamping plate to approach the fixing block.

[0019] Preferably, the driving body is a pneumatic cylinder, a hydraulic oil cylinder and a servo electric cylinder, the driving body is mounted on the back of the fixing block and the piston rod passes through the fixing block and is connected to the clamping plate.

[0020] Preferably, the driving body is a feed screw, which passes through the clamping plate and is connected to the fixing block.

[0021] Compared with the prior art, the utility model has the following beneficial effects:

[0022] The utility model is a bending upper mold clamping device capable of vertical disassembly and assembly. The upper mold is vertically clamped in the upper mold installation area on the fixed block by a slider, and is pressed and fixed by a clamping plate. When the clamping plate approaches one side of the fixed block, the slider will be driven upward. Since the slider is used to vertically install and disassemble the upper mold body, and an anti-falling surface is provided on it, the upper mold body will be driven upward, so that it can finally be moved upward to the installation reference surface, and the upper mold body can also be pressed and fixed laterally. When the clamping plate is away from the fixed block, the slider will move downward relative to the clamping plate together with the upper mold body to complete the vertical downward lowering of the upper mold body, but it will not fall, because the slider is provided with an anti-falling surface to prevent it from falling due to gravity.

[0023] When disassembling the upper mold body (the upper mold body and the slider are separated), moving the upper mold body upward (or obliquely upward) will push the upper contact plate, causing its slider to move along the oblique guide groove and move horizontally relative to the upper mold body until the upper mold body and the anti-fall surface are completely separated, and then quickly fall down to achieve disassembly.

[0024] Since the slider is provided with an upper contact plate, during the upward movement of the upper mold body, due to the weight of the slider itself, if the width of the upper mold is significantly smaller than the width of the slider, when the upper mold body pushes against the upper contact plate, if it does not push to the middle position of the slider, one end of the slider will be lifted up while the other end is subjected to less force and is not lifted up to the same height. This will increase the resistance between the slider and the oblique guide groove, making it easy to get stuck. At the same time, the linearity of the movement will be poor, resulting in severe wear and tear. There will also be a "virtual disassembly" phenomenon in which one end of the anti-fall surface is detached from the upper mold body while the other end is still in the groove of the upper mold body, making it impossible to complete the one-time disassembly. Also, because the splint is provided with holes for the driving member and the guide rod, if the action retaining structure is set on the upper side of the splint, there will be a problem of fewer balance points (usually two to three). Therefore, a waist-shaped hole inclined upward is set at the bottom of the splint. The point can be set according to actual needs, and the holes for the driving member and the guide rod can be effectively avoided. The balance points can be greatly increased. The action retaining member is installed in the waist-shaped hole to prevent this problem from occurring, thereby ensuring the smooth sliding of the inclined guide groove and the slider and the linearity of the movement.

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0032] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0033] Embodiment 1, as Figures 1 to 5 As shown, a bending upper die clamping device capable of vertical quick disassembly and assembly includes a fixed block 10, a clamping plate 20, a slider 30 and an action retaining member 40;

[0034] An upper mold body mounting area 11 is provided at the bottom of the fixed block 10;

[0035] The clamping plate 20 is slidably arranged relative to the fixed block 10 and the distance between the two is adjustable. The clamping plate 20 is provided with an oblique guide groove 21 and a bottom waist-shaped hole 22 connected to the oblique guide groove 21. The oblique guide groove 21 is arranged obliquely upward and is located at the bottom of one side of the clamping plate 20 close to the fixed block 10. The angle between the oblique guide groove 21 and the horizontal plane is 10-89°, and the angle is preferably 45°.

[0036] The slider 30 is slidably matched with the inclined guide groove 21. The slider 30 is used to prevent the upper mold body 50 from falling under the action of gravity, and the upper mold body 50 can be actively separated from the slider 30 vertically. The slider 30 is provided with an anti-falling surface 32 and a pressing surface 33. The anti-falling surface 32 is provided with the bottom of the slider 30 and extends horizontally outward, and the pressing surface 33 is provided on the side of the slider 30 opposite to the upper mold body 50; the slider 30 is also provided with an upper contact plate 31, which is located on the top of the pressing surface 33 and extends outward at least twice the width of the anti-falling surface 32;

[0037] The action retaining member 40 is inserted into the bottom waist-shaped hole 22 and slidably cooperates with the slider 30 .

[0038] Embodiment 2, based on the above embodiment, makes the following improvements:

[0039] like Figures 1 to 5 The lower surface of the oblique guide groove 21 is provided with a plurality of continuously arranged step structures 211; the slider 30 is provided with a sliding surface adapted to the step structure 211 on one side of the lower surface of the oblique guide groove 21. The structural strength of the slider can be ensured, the thickness and volume of the clamping plate can be reduced while ensuring the stroke, and the mounting strength of the slider can be improved.

[0040] Embodiment 3, based on the above embodiment, the following improvements are made:

[0041] like Figures 1 to 5The figure also includes a driving body 60 , which is installed on the fixing block 10 and is used to drive the clamping plate 20 to approach the fixing block 10 .

[0042] Among them, the driving body 60 can be a cylinder, a hydraulic cylinder and a servo electric cylinder. The driving body 60 is installed on the back of the fixed block 10 and the piston rod passes through the fixed block 10 and is connected to the clamp 20. Optimizing the front and rear structural layout on the fixed block can make better use of the space, making the entire clamp system more compact, while providing a larger operating space, which is convenient for the installation, adjustment and replacement of the mold. This layout makes operation and maintenance more convenient and improves work efficiency. The driving parts can be used as universal parts or standard parts of the same type of clamping structure. In this way, when replacing the same type of clamping structure with different specifications, there is no need to replace the driving parts on the rear side, reducing the workload. It can also share the clamping force more evenly to ensure that the upper mold is balanced during the clamping process. This balanced distribution reduces the deformation or displacement of the mold due to uneven force, thereby improving the stability and precision of the processing.

[0043] Among them, Figure 6 As shown, the driving body 60 may also be a feed screw, which passes through the clamping plate 20 and is connected to the fixing block 10 .

[0044] The fixing block 10 is provided with a guide rod, and the clamping plate 20 is provided with a hole for inserting and receiving the guide rod.

[0045] The splint movement can be pneumatic, electric, or hydraulic. Multiple types can be used on the whole machine. Multiple drive parts can adopt a series / parallel structure, which can be operated simultaneously or individually controlled, and can facilitate the rapid assembly and disassembly of multiple cutting tools at the same time. Traditional structures such as feed screws can also be used to complete the movement of the splint close to or away from the fixed block. Pulling back the front side pressure plate from the back through the drive part can reduce the volume of the front structure and facilitate use. At the same time, when replacing different models of molds and splints, only the front structure is removed and the slider is replaced. These are two preset specifications that can be selected in advance. The drive part on the back can still be retained, reducing the workload and having strong versatility.

[0046] When in use, the upper mold body is moved upward from the bottom of the slider, and the upper mold body will squeeze the slider, causing the slider to move obliquely upward along the oblique slide groove, and then the anti-fall surface will move away from the upper mold body. When the upper mold body contacts and drives the upper contact plate to move upward for a distance (the anti-fall surface is slightly lower than the slot of the upper mold body), the upper mold body is moved close to the slider (moving away from the fixed block), the anti-fall surface enters the slot, and the upper mold body falls. The upper mold body and the slider move obliquely downward together to the lowest point, and the driving part drives the splint to approach the fixed block. The splint will drive the slider upward, and the slider will then press the upper mold body against the upper mold body installation area (i.e., the installation reference surface) to complete the clamping work; when disassembling, the upper mold body moves obliquely upward, and when it rises to a certain height, the upper mold body is moved close to the fixed block, the upper mold body and the slider are separated, and the upper mold body can be pulled down to complete the separation and disassembly.

[0047] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution and inventive concept of the utility model should be included in the protection scope of the utility model.
