Description

Technical Field

[0001] The utility model belongs to the technical field of handle bending, and particularly relates to a general bending device for metal profile handles. Background Technique

[0002] Metal profile handles are widely used in fields such as furniture and electronic devices, and bending forming is the main processing method among them. For mass production, using a bending machine for automated production is the most economical and efficient choice. Through preset molds and precise control, the bending machine can quickly and accurately complete the bending of metal profiles, ensuring the consistency and stability of products.

[0003] However, for small batches or customized handles, manual bending forming becomes a necessary technical means. Manual bending requires operators to have an in-depth understanding of metal materials and bending techniques to ensure accurate bending can still be achieved without standardized molds. However, this method has high technical requirements for operators and also increases the processing time and cost.

[0004] Nevertheless, manual bending still plays an important role in small batch or customized production because it can meet the personalized needs of customers and endow products with unique artistic effects. Therefore, in actual production, it is necessary to select a suitable processing method according to specific circumstances to balance production efficiency and cost. Content of the Utility Model

[0005] The purpose of the utility model is to solve the problems of the prior art and propose a general bending device for metal profile handles suitable for small batch customization requirements, which has the advantages of low processing cost, convenient operation, and strong versatility.

[0006] In order to achieve the above purpose, the technical solution provided by the utility model is as follows:

[0007] A general bending device for metal profile handles, comprising a bending platform, a bending fixing plate, a bending plate, a central limiting column, an angle limiting column, and a plurality of profile pads. The bending fixing plate is fixed on the bending platform. One end of the bending plate is connected to one end of the bending fixing plate through a rotating shaft. The bending platform is provided with a plurality of limiting holes on one side of the bending fixing plate. The angle limiting column is installed in one of the limiting holes. The profile pads are installed on the bending fixing plate and the bending plate for limiting the metal profile. The central limiting column is installed on the bending platform. The central limiting column is located on the side of the bending fixing plate facing the limiting hole. When the bending plate contacts the angle limiting column, the farthest perpendicular distance from the tangent plane where the central limiting column contacts the metal profile to the corresponding profile pad is the thickness of the metal profile.

[0008] Further, it further includes an adjustable fixed end block. A fixed end block mounting hole is formed in the bending fixing plate. The fixed end block mounting hole is an elongated hole, and the extending direction of the fixed end block mounting hole is the same as the extending direction of the bending fixing plate. The adjustable fixed end block is perpendicularly mounted on the fixed end block mounting hole towards the limiting hole with respect to the bending fixing plate. An extruded profile mounting hole is formed in the adjustable fixed end block in the extending direction of the bending fixing plate, and the metal extruded profile is fixed on the extruded profile mounting hole through a fixing screw.

[0009] Further, the extruded profile mounting hole is an oblong hole, and the extending direction of the oblong hole is perpendicular to the bending fixing plate.

[0010] Further, it further includes a bending handle, which is fixed to one end of the bending plate away from the bending fixing plate.

[0011] Further, it further includes a reverse limiting post. The reverse limiting post and the limiting hole are located on both sides of the bending plate. When the bending plate and the bending fixing plate are in the same extending direction, the reverse limiting post abuts against the bending plate.

[0012] Compared with the prior art, the remarkable advantages of the present utility model are as follows: it can be applicable to the bending of extruded profile handles with different cross-sections, different heights, different widths, different bending angles, different bending inner angle sizes, and inner angle shapes, meeting the customization requirements. Meanwhile, the operation is convenient, the device is simple, and the processing cost is low. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] In order to make the purpose, technical solutions and advantages of the present utility model more clear and understandable, the present utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] As Figures 1 to 3 shown, a general bending device for a metal profile handle provided by the present utility model includes a bending platform 1, a bending fixing plate 2, a bending plate 3, a central limiting column 4, an angle limiting column 5, a reverse limiting column 6, three profile pads 7, an adjustable fixed end block 8 and a bending handle 9.

[0021] The bending fixing plate 2 is fixed on the bending platform 1. One end of the bending plate 3 is connected to one end of the bending fixing plate 2 through a rotating shaft 10. The bending handle 9 is fixed to the other end of the bending plate 3. The bending handle 9 is used to conveniently operate the bending plate 3 for bending.

[0022] The bending platform 1 is provided with a plurality of limiting holes 11 in the bending direction. The angle limiting column 5 can be installed in any one of the limiting holes 11 according to the angle that the final handle needs to be bent. When the bending plate 3 performs bending, the bending plate 3 stops bending after touching the angle limiting column 5 to meet the requirements of different bending angles of the final handle.

[0023] As Figure 4 shown, the bending fixing plate 2 is provided with a fixed end block mounting hole 12. The fixed end block mounting hole 12 is an elongated hole, and the extending direction of the fixed end block mounting hole 12 is the extending direction of the bending fixing plate 2. The adjustable fixed end block 8 is perpendicularly installed on the bending fixing plate 2 and faces the limiting hole 11 direction in the fixed end block mounting hole 12. The adjustable fixed end block 8 can slide on the bending fixing plate 2 to adjust the height of the final handle. After adjustment, it is fixed to the bending fixing plate 2 through bolts. The three profile pads 7 are installed on the bending fixing plate 2 and the bending plate 3. The first and second profile pads 7 are installed in the fixed end block mounting hole 12 through bolts. The third profile pad 7 is installed on the bending plate 3. The bending plate 3 can also be provided with an elongated hole for installing the third profile pad 7, so that the third profile pad 7 can adjust its position according to the height of the final handle to adapt to the bending of handles with different heights or widths. The three profile pads 7 are used to limit the longitudinal direction of the metal profile. It should be noted that the number of profile pads 7 can be two or more, and the number can be set arbitrarily for the purpose of limiting the distance between the metal profile and the bending platform. The shape of the profile pad 7 is determined according to the shape of the metal profile, and can be an elliptical cross-section, a circular cross-section or other bendable cross-sections.

[0024] The central limit post 4 is installed on the bending platform 1. The central limit post 4 is located on the side of the bending fixing plate 2 facing the limit hole 11. When the bending plate 3 is bent to a predetermined angle, that is, when it contacts the angle limit post 5, the farthest vertical distance from the tangent plane where the central limit post 4 contacts the metal profile to the corresponding profile pad 7 is the thickness of the metal profile. The central limit post 4 with different thicknesses and shapes can be replaced according to the required final inner angle size and shape of the handle. The distance between the profile pad 7 and the bending fixing plate 2 or the bending plate 3 can be adjusted according to the thickness of the metal profile. At the same time, profile pads 7 with different shapes that fit the metal profile can be replaced according to the shape of the metal profile.

[0025] As Figure 5 shown, the adjustable fixed end block 8 is provided with a profile installation hole 13 in the extending direction of the bending fixing plate 2. The profile installation hole 13 is an oblong hole, and its extending direction is perpendicular to the bending fixing plate. The metal profile is fixed on the profile installation hole 13 through a fixing screw. When the thickness of the metal profile is different, the fixing position on the profile installation hole 13 is also different. The setting of the profile installation hole 13 is beneficial to adapting to metal profiles with different thicknesses.

[0026] The reverse limit post 6 and the limit hole 11 are located on both sides of the bending plate 3. When the bending plate 3 and the bending fixing plate 2 are in the same extending direction, the reverse limit post 6 abuts against the bending plate 3. The reverse limit post 6 is used to limit the bending plate 3 and the bending fixing plate 2 in the same direction, which is convenient for fixing the metal profile on the bending plate 3 and the bending fixing plate 2 before bending.

[0027] In one embodiment, before bending, the bending plate 3 is abutted against the reverse limit post 6, the metal profile is placed in the three profile pads 7, the position of the metal profile is adjusted so that the distance from one end of the metal profile to the central limit post 4 is the height of the final handle, the adjustable fixed end block 8 is slid, the other end of the metal profile is fixed on the profile installation hole 13, and the bolt for fixing the adjustable fixed end block 8 is tightened.

[0028] The angle limit post 5 is installed on one of the limit holes 11, and the metal profile is bent once around the central limit post 4 by rotating the bending plate 3. The bending stops when the bending plate 3 touches the angle limit post 5.

[0029] Rotate the bending plate 3 so that it abuts against the reverse limit post 6, loosen the bolt for fixing the adjustable fixed end block 8, slide the adjustable fixed end block 8 so that the distance from the first bend of the metal profile to the central limit post 4 is the width of the final handle, and the distance from the end of the metal profile connected to the adjustable fixed end block 8 to the central limit post 4 is the height of the final handle. Tighten the bolt for fixing the adjustable fixed end block 8. Rotate the bending plate 3 to bend the metal profile a second time around the central limit post 4. The bending stops when the bending plate 3 touches the angle limit post 5. Then the final handle can be obtained.

[0030] Through a special structural form, the utility model can meet the requirements of small-batch customization. At the same time, this structure has low processing costs, strong versatility, and convenient operation.

[0031] The above-described embodiments merely represent one or several implementation manners of the utility model, and the description thereof is relatively specific and detailed. However, it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the utility model, several variations and improvements can still be made, and these all fall within the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
