Description

Technical Field

[0001] This utility model relates to the technical field of metal mold processing, specifically a surface smoothing treatment device for metal bending tools. Background Technology

[0002] Metal molds are forming tools made of metal materials (such as steel and cemented carbide). Different molds have specific contours or internal cavity shapes, and are classified according to their uses, such as round tube molds, straight molds, curved molds, and U-shaped molds. During mold processing, edge protrusion problems caused by processing technology or material characteristics result in burrs on the mold surface. These burrs not only impair the aesthetic appearance of the parts but also interfere with their precision and inspection accuracy, accelerate wear, and may cause problems in the hydraulic system. In severe cases, they can even lead to the scrapping of the parts. Therefore, it is necessary to smooth the mold surface.

[0003] Existing smoothing equipment typically employs mechanical polishing for smoothing metal bending fixtures. This involves using electric equipment (such as bidirectional rotary polishers or eccentric grinders) in conjunction with polishing pads like wool or foam pads, achieving batch processing through high-speed grinding. When polishing the surface of metal bending fixtures, the fixtures are usually clamped and positioned to prevent displacement during polishing. However, after polishing, the clamps must be released, making the polishing process cumbersome and reducing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a surface smoothing treatment device for metal bending tools 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 surface smoothing treatment device for metal bending tools includes a grinding mechanism, a feeding mechanism, and a discharging mechanism. The grinding mechanism includes an operating table, on which a mounting frame is fixed. The mounting frame is provided with a reciprocating grinding component capable of smoothing the metal bending tool.

[0007] Symmetrically arranged limiting members are installed on the operating table. Under the pressure of the limiting members, the grinding end of the metal bending tool can abut against the reciprocating grinding part.

[0008] An intermittent drive component is installed on the operating table and can be connected to the reciprocating grinding component and the limiting component respectively.

[0009] The surface smoothing equipment for metal bending tools as described above: baffles with an inclined structure are symmetrically and fixedly installed on the operating table, and the two ends of the metal bending tool abut against the baffles respectively during grinding.

[0010] The surface smoothing equipment for metal bending tools as described above: the reciprocating grinding component includes a deflection shaft rotatably mounted on the mounting frame, two parallel connecting plates are fixedly connected to the deflection shaft, and a polishing pad capable of abutting against the metal bending tool is detachably mounted on the end of the connecting plate away from the deflection shaft.

[0011] The surface smoothing equipment for metal bending tools as described above: the limiting member includes a first grooved roller rotatably mounted on the operating table, a first groove formed on the first grooved roller, a movable cylinder arranged along the axial direction of the first groove, a first ball bearing movably arranged on the inner wall of the movable cylinder and adapted to slide in the first groove, and a clamping plate with an arc-shaped structure and slidably connected to the operating table is fixedly installed on the end of the movable cylinder away from the first grooved roller.

[0012] The surface smoothing equipment for metal bending tools as described above: the intermittent drive component includes a second grooved roller rotatably mounted on the operating table, the second grooved roller having a second sliding groove formed on it, and the second grooved roller being driven to rotate by a motor fixedly mounted on the operating table;

[0013] It also includes a connecting sleeve, which is arranged along the axial direction of the second groove roller. A second ball bearing that is movably arranged on the inner wall of the connecting sleeve and is adapted to slide in the second groove is provided. When the connecting sleeve moves, the first drive shaft and the second drive shaft mounted on the operating table can be controlled to rotate intermittently through the connecting clamp.

[0014] The surface smoothing equipment for metal bending tools as described above: the two ends of the first drive shaft are respectively connected to the first groove roller through the second bevel gear set, and a first limiting groove is formed on the first drive shaft. A first sleeve fixed to the connecting hoop is slidably sleeved along the axial direction of the first drive shaft.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] After the loading mechanism transfers the unprocessed metal bending jig to the operating table, the intermittent drive is activated, causing two limiting components to move simultaneously towards the metal bending jig. While limiting the metal bending jig, the limiting components ensure that it remains in contact with the reciprocating grinding component during grinding. After the limiting components move, under the control of the intermittent drive, the reciprocating grinding component can reciprocate and deflect multiple times relative to the metal bending jig. During this deflection, the reciprocating grinding component moves back and forth on the surface of the metal bending jig, generating alternating thrust and pull forces. The clamping and limiting of the metal bending jig by the clamping plates and the intermittent grinding of the metal bending jig surface by the polishing pad ensure grinding efficiency, effectively removing burrs from the surface of the metal bending jig and forming a uniform, bright surface. This also facilitates the loading and unloading of the metal bending jig after grinding. Attached Figure Description

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-6 In this embodiment of the utility model, a surface smoothing treatment device for metal bending tools includes a grinding mechanism, a feeding mechanism and a discharging mechanism. The grinding mechanism includes an operating table 1, a mounting frame 2 fixed on the operating table 1, and a reciprocating grinding component capable of smoothing the metal bending tool on the mounting frame 2.

[0029] Symmetrically arranged limiting members are installed on the operating table 1. Under the pressure of the limiting members, the grinding end of the metal bending tool can abut against the reciprocating grinding part.

[0030] An intermittent drive component is installed on the operating table 1 and can be connected to the reciprocating grinding component and the limiting component respectively.

[0031] In this embodiment, after the loading mechanism transfers the unprocessed metal bending die to the operating table 1, it activates the intermittent drive component, causing two limiting components to move simultaneously toward the metal bending die. While limiting the metal bending die, the limiting components ensure that the metal bending die remains in contact with the reciprocating grinding component during grinding. After the limiting components move, under the control of the intermittent drive component, the reciprocating grinding component can reciprocate and deflect multiple times relative to the metal bending die. During this deflection, the reciprocating grinding component moves back and forth on the surface of the metal bending die, generating alternating thrust and pull forces. This effectively removes burrs from the surface of the metal bending die, forming a uniform, bright surface. The cooperation between the limiting components and the reciprocating grinding component ensures the grinding effect of the metal bending die and facilitates the loading and unloading of the metal bending die after grinding.

[0032] When the limiting component performs the pressing or resetting action, the loading mechanism and the unloading mechanism can complete the loading and unloading work of the metal bending die respectively, ensuring that the unloading mechanism unloads the metal bending die after the limiting component is reset and separated from the metal bending die, and the loading mechanism has completed the loading work before the limiting component performs the pressing action and comes into contact with the metal bending die.

[0033] Preferably, the operating table 1 is symmetrically and fixedly equipped with baffles 3 arranged in an inclined structure. When the metal bending tool is being ground, both ends abut against the baffles 3 respectively. Under the pressure of the limiting component and the restriction of the baffles 3, the metal bending tool can be automatically guided.

[0034] For further solutions to this utility model, please refer to [link / reference]. Figure 3 The reciprocating grinding component includes a deflection shaft 4 rotatably mounted on the mounting bracket 2. Two parallel connecting plates 5 are fixedly connected to the deflection shaft 4. A polishing pad 6 that can abut against the metal bending tool is detachably mounted on the end of the connecting plate 5 away from the deflection shaft 4.

[0035] In one embodiment, the polishing pad 6 and the connecting plate 5 can be fixed together by bolts.

[0036] Specifically, after the two ends of the metal bending tool abut against the baffle 3, the deflection shaft 4 reciprocates under the drive of the intermittent drive component. When the deflection shaft 4 rotates, the polishing pad 6 rubs against the surface of the metal bending tool under the drive of the connecting plate 5. During the reciprocating process, uniform pressure is continuously applied to the surface of the bending tool to maintain close contact between the polishing pad 6 and the surface of the metal bending tool. Through repeated reciprocating grinding, the surface roughness of the metal bending tool is gradually reduced, forming a uniform bright surface.

[0037] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The limiting component includes a first grooved roller 9 rotatably mounted on the operating table 1. A first sliding groove 901 is formed on the first grooved roller 9. A movable cylinder 10 is arranged along the axial direction of the first sliding groove 901. A first ball bearing 1001 that is movably matched with the first sliding groove 901 is movably arranged on the inner wall of the movable cylinder 10. A clamping plate 11 with an arc-shaped structure and slidably connected to the operating table 1 is fixedly installed on the end of the movable cylinder 10 away from the first grooved roller 9.

[0038] In one embodiment, after the feeding mechanism transfers the metal bending tool to the operating table 1 for unloading, it cannot guarantee that the metal bending tool will always be in contact with the polishing pad 6. In another embodiment, the position of the clamping plate 11 is fixed, and the feeding mechanism must ensure that the metal bending tool is between the clamping plate 11 and the baffle 3 when unloading, which requires high precision in the feeding mechanism. In this embodiment, the movable clamping plate 11 can ensure that the metal bending tool is always in contact with the polishing pad 6, and no mechanical cooperation is required during unloading, which requires high precision.

[0039] For further solutions to this utility model, please refer to [link / reference]. Figure 5 The intermittent drive component includes a second grooved roller 13 rotatably mounted on the operating table 1. A second groove 1301 is formed on the second grooved roller 13. The second grooved roller 13 is driven to rotate by a motor 14 fixedly mounted on the operating table 1.

[0040] It also includes a connecting sleeve 18, which is arranged along the axial direction of the second groove roller 13. A second ball bearing is movably arranged on the inner wall of the connecting sleeve 18 and is adapted to slide in the second groove 1301. When the connecting sleeve 18 moves, the first drive shaft 15 and the second drive shaft 16, which are rotated and mounted on the operating table 1, can be controlled to rotate intermittently through the connecting clamp 17.

[0041] The two ends of the first drive shaft 15 are respectively connected to the first grooved roller 9 through the second bevel gear set 12, and a first limiting groove 1501 is formed on the first drive shaft 15. A first sleeve 19 fixed to the connecting hoop 17 is slidably sleeved along the axial direction of the first drive shaft 15. A third ball is movably arranged on the inner wall of the first sleeve 19, which is slidably adapted to the first limiting groove 1501.

[0042] The second drive shaft 16 is connected to the central shaft 8 rotatably mounted on the mounting bracket 2 via a toothed belt 21. The central shaft 8 is connected to the deflection shaft 4 via a first bevel gear set 7. A second limiting groove 1601 is formed on the second drive shaft 16. A second sleeve 20 fixed to the connecting hoop 17 is slidably sleeved along the axial direction of the second drive shaft 16. A fourth ball bearing is movably disposed on the inner wall of the second sleeve 20 and is slidably adapted to the second limiting groove 1601.

[0043] It should be noted that: the first limiting groove 1501 includes a threaded groove A and a straight groove B, and the second limiting groove 1601 includes a straight groove a and a multi-segment composite groove (threaded groove b, straight groove c, threaded groove d, and straight groove e). Among them, the thread directions of threaded groove b and threaded groove d are opposite, and when the fourth ball moves in threaded groove b and threaded groove d respectively, the rotation direction of the deflection shaft 4 is opposite.

[0044] In detail, when the grinding work begins, the motor 14 is started. The output shaft of the motor 14 is fixed to the second grooved roller 13, so that when the output shaft rotates, it can drive the second grooved roller 13 to rotate simultaneously. With the cooperation of the second slide groove 1301 and the second ball bearing, the second grooved roller 13 rotates back and forth once. Meanwhile, the connecting sleeve 18 completes a set of reciprocating movements along the axial direction of the second grooved roller 13. While the connecting sleeve 18 moves, under the drive of the connecting clamp 17, the first sleeve 19 and the second sleeve 20 can respectively move relative to the first transmission. The movement of the moving shaft 15 and the second transmission shaft 16 is achieved by the cooperation of the first limiting groove 1501 and the third ball, and the cooperation of the second limiting groove 1601 and the fourth ball, so as to meet the requirement of the intermittent rotation of the first transmission shaft 15 and the second transmission shaft 16. The clamping and limiting of the metal bending tool by the clamping plate 11 and the polishing of the surface of the metal bending tool by the polishing pad 6 cooperate with each other without affecting each other, so that the burrs on the surface of the metal bending tool can be effectively removed, forming a uniform bright surface, while facilitating the loading and unloading of the metal bending tool after polishing.
