Description

Technical Field

[0001] This utility model relates to the field of bending machine technology, and in particular to a segmented wedge block electric deflection compensation device. Background Technology

[0002] When a bending machine is operating, the hydraulic cylinders on both sides of the slide push the slide downwards. During the bending process, the slide, worktable, and machine bed of the bending machine will undergo parabolic deflection deformation due to the force applied. This results in a reduction in the actual downward pressure in the middle of the sheet metal, leading to inconsistent bending angles of the workpiece. Consequently, the angle of the bent workpiece cannot be guaranteed to be consistent along its entire length, affecting the forming angle of the bent part. In addition, localized wear of the bending die also affects the straightness of the bent workpiece. Therefore, deflection compensation is necessary.

[0003] Existing deflection compensation devices mostly use electric wedge type and hydraulic type. Hydraulic compensation is relatively rough and has low precision; electric wedge type uses integral wedge blocks, but as the bending length of the bed increases, the machining of such integral wedge blocks is difficult and costly.

[0004] This practical segmented wedge block electric deflection compensation device is designed to solve this problem. It not only significantly improves machining accuracy and reduces debugging time and waste, but also makes disassembly and assembly convenient, facilitates maintenance, improves efficiency, and reduces operating difficulty.

[0005] This practical electric deflection compensation device has a simple structure, compact size, and is easy to manufacture and install. It features stable performance, safety and reliability, and high cost-effectiveness, and has high value for promotion and application. Utility Model Content

[0007] The technical solution of this utility model to solve the technical problem is as follows: a segmented wedge block electric deflection compensation device, including a cover plate, an upper wedge block group and a lower wedge block group, wherein the lower wedge block group is correspondingly arranged with the upper wedge block group, and one end of the lower wedge block group is connected to a push-pull mechanism. The push-pull mechanism includes a push-pull block connected to the lower wedge block group through a short connection, and a driving component connected to the push-pull block for transmission. A left stop block for limiting the upper wedge block group and the lower wedge block group is provided at the end of the cover plate away from the push-pull mechanism, and a limiting block for limiting the upper wedge block group is provided at the end of the upper wedge block group near the push-pull mechanism. An installation groove is provided on the cover plate, and the upper wedge block group is connected to the cover plate by a positioning key connected in the installation groove and a bolt. A through groove is opened on the upper surface of the cover plate along the length direction, and the upper wedge block group and the lower wedge block group are arranged in the through groove.

[0008] Preferably, the lower wedge block group includes lower wedge block I, lower wedge block II, lower wedge block III, lower wedge block IV and lower wedge block V. The slope angle of lower wedge block III is greater than that of lower wedge block II and lower wedge block IV. The angles of lower wedge block II and lower wedge block IV are greater than those of lower wedge block I and lower wedge block V. The lower wedge blocks are connected to each other as a whole by connecting plates.

[0009] Preferably, the upper wedge block group includes upper wedge block I, upper wedge block II, upper wedge block III, upper wedge block IV and upper wedge block V. Upper wedge block I cooperates with lower wedge block I, upper wedge block II cooperates with lower wedge block II, upper wedge block III cooperates with lower wedge block III, upper wedge block IV cooperates with lower wedge block IV, and upper wedge block V cooperates with lower wedge block V.

The above technical solution has the following advantages or beneficial effects: 1. This practical electric deflection compensation device has a simple structure, compact size, and is easy to manufacture and install. It features stable performance, safety and reliability, and high cost performance, and has high value for promotion and application. 2. This practical segmented wedge block electric deflection compensation device is designed to solve this problem. It not only significantly improves machining accuracy and reduces debugging time and waste, but also makes disassembly and assembly convenient, facilitates maintenance, improves efficiency, and reduces operating difficulty. 3. By setting a disc spring outside the spacer of the positioning key, when the lower wedge is pushed out, the total thickness of the middle wedge is high on both sides, causing the middle of the cover plate to arch up and generate pre-deflection deformation. At this time, the middle of the disc spring has a large compression. When the lower wedge returns to its original position, the total thickness of the middle wedge is consistent with the two sides. The disc spring can help the cover plate fall back to the starting height and ensure the stability of the bolt connection on the positioning key. Attached Figure Description

Detailed Implementation

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific implementation methods and in conjunction with the accompanying drawings.

[0018] Example 1 See Figures 1 to 10 A segmented wedge block electric deflection compensation device includes a cover plate 1, an upper wedge block group, and a lower wedge block group. The lower wedge block group is correspondingly arranged with the upper wedge block group. One end of the lower wedge block group is connected to a push-pull mechanism. The push-pull mechanism includes a push-pull block 16 connected to the lower wedge block group through a short connection 22, and a drive component that is pulsatorically connected to the push-pull block 16. A left stop block 21 for limiting the upper and lower wedge block groups is provided at the end of the cover plate 1 away from the push-pull mechanism. A limiting block 19 for limiting the upper wedge block group is provided at the end of the upper wedge block group near the push-pull mechanism. An installation groove 101 is provided on the cover plate 1. The upper wedge block group is connected to the cover plate 1 by a positioning key 2 connected in the installation groove 101 and a bolt. A through groove 102 is opened along the length direction on the upper surface of the cover plate 1. The upper and lower wedge block groups are arranged in the through groove 102.

[0019] The lower wedge block assembly includes lower wedge block I4, lower wedge block II5, lower wedge block III6, lower wedge block IV7, and lower wedge block V12. The slope angle of lower wedge block III6 is greater than that of lower wedge block II5 and lower wedge block IV7, and the angles of lower wedge block II5 and lower wedge block IV7 are greater than those of lower wedge block I4 and lower wedge block V12. The lower wedge blocks are connected to each other as a whole by connecting plates.

[0020] The upper wedge block group includes upper wedge block I8, upper wedge block II9, upper wedge block III10, upper wedge block IV11 and upper wedge block V3. Upper wedge block I8 cooperates with lower wedge block I4, upper wedge block II9 cooperates with lower wedge block II5, upper wedge block III10 cooperates with lower wedge block III6, upper wedge block IV11 cooperates with lower wedge block IV7, and upper wedge block V3 cooperates with lower wedge block V12.

[0021] The driving component includes a lead screw shaft 17, a drive shaft 18, a motor 171, and an outer cover 20. The outer cover 20 is connected to the cover plate 1. The lead screw shaft 17 is installed in the outer cover 20 through a bearing seat 15. The drive shaft 18 is internally engaged with the lead screw shaft 17. The push-pull block 16 is connected to the output end of the drive shaft 18. The lead screw shaft 17 is driven by the motor 171.

[0022] The upper surface of the positioning key 2 is flush with the surface of the cover plate 1.

[0023] The positioning key 2 is provided with a spacer 13, and a gasket 14 is provided on the side of the spacer 13 near the positioning key 2. A disc spring 131 is provided on the outside of the spacer 13.

[0024] Both the upper wedge block group and the lower wedge block group are arranged in an array.

[0025] Working principle The wedges work in pairs and convert horizontal pushing and pulling into vertical lifting. The lower wedge group moves axially in a straight line under the drive of the pushing and pulling mechanism, forming a relative sliding with the upper wedge group fixed on the cover plate 1, thereby generating different vertical lifting amounts at each segment and applying pre-deflection to the cover plate 1 or its load-bearing components.

[0026] The upper wedge block group consists of upper wedge blocks with different angles; the lower wedge block group consists of lower wedge blocks with different angles, and they are connected as a whole by a connecting plate. Since the lower wedge block group is pushed as a whole, the horizontal displacement of each segment is the same, but the vertical displacement is different due to the different wedge angles of each segment, thus forming a deflection curve.

[0027] Motor 171 drives lead screw 17, lead screw 17 is connected to drive shaft 18, drive shaft 18 pushes push-pull block 16, push-pull block 16 drives the lower wedge block group to reciprocate as a whole through short connection 22, so as to achieve continuous and controllable lifting amount.

[0028] A spacer 13, a washer 14, and a disc spring 131 are provided at the positioning key 2 to form an elastic clamping and pre-tightening mechanism. When the middle part is lifted by the wedge block, the disc spring 131 is compressed and stores energy; when it retracts, the disc spring 131 releases energy to assist the cover plate 1 in returning to its original position and maintain the pre-tightening stability of the positioning key 2 bolt, reducing loosening.

[0029] The left stop 21 at the end of the cover plate 1 away from the push-pull mechanism limits the extreme position of the wedge group; the limit block 19 near the drive end limits the stroke of the upper wedge block; the mounting groove 101 cooperates with the positioning key 2 and the bolt to ensure the axial positioning and shear bearing capacity of the upper wedge block group.

[0030] The upper wedge block assembly is fixed to the cover plate 1. It is divided into two parts and angles, and it bears the inclined surface contact with the lower wedge block to convert the horizontal displacement into vertical lifting. The positioning key 2 is installed into the mounting groove 101 with the bolt. The upper surface of the positioning key 2 is flush with the surface of the cover plate 1 to ensure flatness.

[0031] The lower wedge block is composed of separate angles and connected as a whole by a connecting plate to ensure equal stroke and differential lift in each segment when pushed or pulled.

[0032] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not a limitation on the scope of protection of the present utility model. Based on the technical solution of the present utility model, various modifications or variations that can be made by those skilled in the art without creative effort are still within the scope of protection of the present utility model.
