Description

Technical Field

[0001] This utility model relates to the field of bending equipment technology, and in particular to a bending center insert die selection device and a bending center. Background Technology

[0002] Currently, existing bending centers generally consist of a pressing mechanism and a bending mechanism. The pressing mechanism clamps the sheet metal using an upper pressure blade assembly, and the bending mechanism then bends the sheet metal. During the bending operation, the upper pressure blade assembly needs to align the blades according to the bending length of the sheet metal. To improve blade alignment accuracy, existing bending centers use insert dies with multiple blades to select blades to adapt to different bending lengths. However, the blade selection method of existing insert dies is complex, structurally unstable, and has poor load-bearing capacity. When using heavier blades, misalignment occurs, affecting bending accuracy. Utility Model Content The purpose of this utility model is to provide a bending center insert die selection device and a bending center to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0021] Reference Figures 1-6 The bending center insert die selection device of this utility model is implemented in the following embodiments: like Figure 1 and Figure 2 As shown, the bending center insert die knife selection device of this utility model includes: a base 100, a knife shaft 200, a pressing blade 300, and a knife selection drive mechanism 400.

[0022] Among them, such as Figure 1 and Figure 2 As shown, the front side of the base 100 is provided with a first fixing seat 110 and a second fixing seat 120 spaced apart along a first direction. In this embodiment, the first direction is defined as the left and right direction. It can be understood that the first fixing seat 110 and the second fixing seat 120 are fixed at intervals from left to right on the front side of the base 100, and a gap is formed between the first fixing seat 110 and the second fixing seat 120 for placing the pressure blade 300.

[0023] In this embodiment, the cutter shaft 200 also extends in the left-right direction, wherein, for example... Figure 3 As shown, the cutter shaft 200 includes a first shaft body 210 and a second shaft body 220 coaxially connected from left to right. The second shaft body 220 is a hollow shaft structure. The outer peripheral wall of the first shaft body 210 is provided with at least one first limiting part 211 extending along the axial direction, while the outer peripheral wall of the second shaft body 220 is provided with at least one second limiting part 221 extending along the axial direction.

[0024] like Figure 4 As shown, in this embodiment, a connecting shaft 212 is coaxially fixed to the right end of the first shaft 210. The connecting shaft 212 is rotatably fixed inside the second shaft 220 so that the first shaft 210 can rotate circumferentially relative to the second shaft 220 to a position where the first limiting part 211 and the second limiting part 221 are axially opposite each other, and the first shaft 210 and the first shaft 210 are axially fixedly arranged relative to each other. In this embodiment, the connecting shaft 212 is entirely fitted inside the second shaft 220.

[0025] In this embodiment, the cutter shaft 200 is slidably mounted on the first fixed base 110 and the second fixed base 120 in the left-right direction. The second shaft 220 is always fixedly positioned relative to the second fixed base 120 in the circumferential direction. It is understood that when the first shaft 210 rotates, the second shaft 220 does not rotate with the first shaft 210; however, when the first shaft 210 moves in the left-right direction, the second shaft 220 moves with the first shaft 210. In this embodiment, the cutter shaft 200 is supported by the first fixed base 110 and the second fixed base 120.

[0026] The first shaft 210 of this utility model is connected to the second shaft 220 through the connecting shaft 212 to realize relative rotation between the first shaft 210 and the second shaft 220 and relative fixation along the axial direction, thereby improving the structural strength of the cutter shaft 200. Furthermore, under the support of the first fixed seat 110 and the second fixed seat 120 on the cutter shaft 200, the load-bearing capacity is further improved, which can meet the needs of heavier pressing blades 300 and more pressing blades 300, thereby increasing the clamping force on the workpiece.

[0027] The pressing blade 300 in this embodiment has multiple blades, such as... Figure 5 As shown, the pressing blade 300 is provided with a sleeve hole 310 that fits with the cutter shaft 200. The sleeve hole 310 is provided with at least one third limiting part 311. The third limiting part 311 is used to engage with the first limiting part 211 and the second limiting part 221 in the axial direction to fix the position of the pressing blade 300 relative to the cutter shaft 200 in the circumferential direction. Multiple pressing blades 300 are arranged and stacked in the left-right direction between the first fixing seat 110 and the second fixing seat 120.

[0028] In this embodiment, the first limiting part 211 and the second limiting part 221 are both boss structures, while the third limiting part 311 is a groove structure. The first shaft 210 and the second shaft 220 are both spline shafts. A plurality of first limiting parts 211 are circumferentially spaced on the outer peripheral wall of the first shaft 210, a plurality of second limiting parts 221 are circumferentially spaced on the outer peripheral wall of the second shaft 220, and correspondingly, a plurality of third limiting parts 311 are circumferentially distributed in the socket 310.

[0029] In this embodiment, the tool selection drive mechanism 400 is connected to the first shaft 210 for transmission. The tool selection drive mechanism 400 is used to drive the first shaft 210 to rotate around its own axis and to reciprocate in the left and right directions.

[0030] Based on the bending length range, the tool selection drive mechanism 400 drives the first shaft 210 to rotate, aligning the first limiting part 211 with the second limiting part 221 axially. Then, the first shaft 210 moves left and right, causing the second shaft 220 to move left and right together. This controls the first shaft 210 to engage with a corresponding number of pressing blades 300. At this time, some pressing blades 300 are fitted onto the first shaft 210, and others onto the second shaft 220. The third limiting part 311 in the socket 310 engages with the corresponding first limiting part 211 and second limiting part 221 to restrict the rotation of the pressing blades 300. Then, the mechanism drives... The first shaft 210 rotates to drive the pressure blade 300 sleeved on the first shaft 210 to rotate, so that the pressure blade 300 sleeved on the first shaft 210 and the pressure blade 300 sleeved on the second shaft 220 are offset in the circumferential direction to realize the tool selection operation. In this embodiment, the pressure blade 300 sleeved on the second shaft 220 is used to press and bend the workpiece. If it is necessary to increase the pressure blade 300, when selecting the tool, the first shaft 210 is moved to the left to transfer the pressure blade 300 to the second shaft 220. If it is necessary to reduce the pressure blade 300, when selecting the tool, the first shaft 210 is moved to the right to transfer the pressure blade 300 to the first shaft 210.

[0031] like Figure 4 As shown, in this embodiment, the inner ends of the second shaft 220 are respectively fixedly fitted with rotating bearings 222, and the connecting shaft 212 is rotatably fixedly connected to the two rotating bearings 222 respectively, so as to realize the rotational cooperation between the first shaft 210 and the second shaft 220 in the circumferential direction and the fixation in the axial direction, further improving the stability of the connection between the connecting shaft 212 and the second shaft 220, and improving the overall structural strength of the cutter shaft 200.

[0032] like Figure 1 and Figure 4 As shown, the first fixed base 110 of this embodiment is provided with a first sleeve hole 111, and a sliding sleeve 112 is fixedly sleeved in the first sleeve hole 111. The cutter shaft 200 is rotatably and axially sliding sleeve 112 is provided in the sliding sleeve 112. The sliding sleeve 112 can improve the smoothness of the sliding of the cutter shaft 200.

[0033] like Figure 4 and Figure 6 As shown, the second fixed base 120 is provided with a second sleeve hole 121, and a limiting sleeve 122 is fixedly sleeved in the second sleeve hole 121. The inner circumferential surface of the limiting sleeve 122 is provided with a circumferential limiting part 123. The second shaft 220 is axially slidably sleeved 112 inside the limiting sleeve 122. The circumferential limiting part 123 and the second limiting part 221 are axially slidably engaged to restrict the rotation of the second shaft 220.

[0034] In this embodiment, the circumferential limiting part 123 has a groove structure, and multiple circumferential limiting parts 123 are distributed circumferentially on the inner circumferential wall of the limiting sleeve 122.

[0035] like Figure 1 and Figure 2 As shown, the tool selection drive mechanism 400 in this embodiment includes a moving drive component 410 and a rotating drive component 420. The moving drive component 410 is used to drive the first shaft 210 to move back and forth in the left and right direction, and the rotating drive component 420 is used to drive the first shaft 210 to rotate around its own axis.

[0036] Specifically, the movable drive assembly 410 of this embodiment includes a lead screw 411 extending in the left-right direction, a transverse drive member 412 that drives the lead screw 411 to rotate, and a movable nut seat 413 threadedly connected to the lead screw 411. The movable nut seat 413 is slidably mounted on the base 100 in the left-right direction. The rotation drive assembly 420 includes a rotation drive member 421 mounted on the movable nut seat 413. The rotation drive member 421 is connected to the left end of the first shaft 210. The transverse drive member 412 is fixedly mounted on the base 100. In this embodiment, the transverse drive member 412 drives the lead screw 411 to rotate, thereby driving the movable nut seat 413 to move in the left-right direction, thereby driving the rotation drive member 421 and the first shaft 210 to move in the left-right direction. The rotation drive member 421 directly drives the first shaft 210 to rotate.

[0037] In this embodiment, the left end of the first shaft 210 is rotatably connected to the movable nut seat 413, further improving the stability of the structure.

[0038] Both the transverse drive component 412 and the rotary drive component 421 are servo motors.

[0039] In this embodiment, the right end of the lead screw 411 is rotatably connected to the first fixed base 110, and the left end of the lead screw 411 is connected to the transverse drive component 412.

[0040] Furthermore, this embodiment also includes a transverse drive mechanism 500, which drives the base 100 to move back and forth in the left and right directions to adjust the overall position of the pressure blade 300 in the left and right directions.

[0041] Specifically: such as Figure 6 As shown, the transverse drive mechanism 500 includes a base 510 and a transverse drive assembly (not shown).
