Description

Technical Field

[0001] The utility model relates to the field of bending equipment, in particular to an upper and lower pressing rotating mechanism which can extend the feeding length of a workpiece. Background Art

[0002] For example, in the authorized patent CN213530533U in the prior art, an upper clamping mechanism and a clamping mechanism are arranged in the upper and lower clamping rotating mechanism of a U-shaped feeding device of a bending machine. Most bending machines choose to adopt a feeding method arranged on a loading and unloading platform. This feeding form has certain advantages, but also has certain limitations. For example, the workpiece sent out is restricted by the clamping and conveying of the upper and lower pressure heads, and the length of the workpiece that can be fed into the bending head of the bending machine for processing is limited, resulting in the size of the finished workpiece being limited by the feedable length and unable to be further miniaturized. For this reason, we designed an upper and lower clamping rotating mechanism that can extend the feeding length of the workpiece based on the existing upper and lower clamping rotating mechanism of the U-shaped feeding device of the bending machine. Utility Model Content

[0003] The purpose of the utility model is to provide an upper and lower pressing and rotating mechanism capable of extending the feeding length of a workpiece, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: an upper and lower clamping rotating mechanism that can extend the feeding length of the workpiece, comprising a main body and an upper pressure claw and a lower pressure claw respectively installed on the two execution ends of the main body, and a magnetic suction unit is installed on the outer wall of the upper pressure claw.

[0005] Furthermore, the magnetic unit is detachably connected to the outer wall of the upper pressing claw.

[0006] Furthermore, the magnetic attraction unit is a strong magnet with a cubic structure.

[0007] Furthermore, the magnetic attraction unit is an electrically controlled magnet.

[0008] Furthermore, a motor is installed at one end of the upper pressure claw away from the mounting bracket, and the execution end of the motor penetrates the outer wall of the upper pressure claw and is transmission-connected with the mounting bracket.

[0009] Furthermore, a motor is installed at one end of the upper pressure claw away from the mounting bracket, and the execution end of the motor penetrates the outer wall of the upper pressure claw and is transmission-connected with the mounting bracket.

[0010] The beneficial effect achieved by the utility model is that by adding a magnetic suction unit on the outer wall of the upper pressure claw, the length of the workpiece that can be fed into the bending head of the bending machine for processing is increased, thereby miniaturizing the size of the finished workpiece.

[0018] The utility model is further described below in conjunction with the accompanying drawings.

[0019] Embodiment 1

[0020] like Figure 1 and 2 As shown, embodiment 1 discloses an upper and lower clamping rotating mechanism capable of extending the feeding length of a workpiece, comprising: a main body 1 and an upper clamping jaw 2 and a lower clamping jaw respectively mounted on two execution ends of the main body 1, and a magnetic suction unit is mounted on the outer wall of the upper clamping jaw 2.

[0021] Based on the above structure, Figure 1 and 2 As shown, when in use, the two execution ends of the main body 1 drive the upper pressure jaw 2 and the lower pressure jaw to clamp the workpiece and transport it to the designated position for bending. When the workpiece needs to be further sent to the bending head of the bending machine for processing, the upper pressure jaw 2 and the lower pressure jaw release the clamping of the workpiece, and the execution end of the main body 1 connected to the upper pressure jaw 2 drives the upper pressure jaw 2 to adjust the position of the magnetic suction unit 3 until the magnetic suction unit 3 magnetically fixes the upper surface of the workpiece, and then the workpiece is continued to be sent to the bending head for bending through the magnetic suction unit 3, thereby increasing the length of the workpiece that can be sent to the bending head of the bending machine for processing, thereby miniaturizing the size of the finished workpiece.

[0022] Further, such as Figure 1 and 2As shown, in order to facilitate the replacement of the magnetic unit, the magnetic unit and the outer wall of the upper pressing claw are detachably connected;

[0023] The specific magnetic suction unit is fixed to the upper pressure claw by multiple bolts.

[0024] Further, such as Figure 1 and 2 As shown, the magnetic attraction unit 3 is a strong magnet 3A with a cubic structure;

[0025] Specifically, when the connection surface between the workpiece and the strong magnet 3A is horizontal, the bottom of the strong magnet 3A is magnetically fixed to the top of the workpiece, and then the workpiece is fed into the bending head for bending. The length of the cross-section where the bottom end of the strong magnet 3A is magnetically fixed to the top of the workpiece is determined according to the length of the workpiece that needs to be fed in (the length of the bottom end of the cross-section of the strong magnet 3A - the length of the workpiece that needs to be fed in = the length of the cross-section for magnetic fixation). When the connection surface between the workpiece and the strong magnet 3A is vertical, the strong magnet 3A can be directly magnetically fixed to the workpiece through the end away from the upper pressure claw 2.

[0026] Embodiment 2

[0027] like Figure 3 As shown, the technical feature that distinguishes the second embodiment from the first embodiment is that the magnetic unit 3 is an electro-controlled magnet 3B. The arrangement of the electro-controlled magnet 3B facilitates the release of the magnetic fixation between the magnetic unit and the workpiece, and also avoids the wear on the workpiece surface when the magnetic fixation between the magnetic unit and the workpiece is released.

[0028] Embodiment 3

[0029] like Figure 4 As shown, the technical feature of the third embodiment differs from the second embodiment in that there are two electro-controlled magnets 3B, which are connected to the outer wall of the upper pressure claw through the mounting bracket 3C, and the two electro-controlled magnets 3B are detachably connected to the mounting bracket 4, and the actuating end of one of the electro-controlled magnets 3B is arranged to the side away from the upper pressure claw, and the actuating end of the other electro-controlled magnet 3B is arranged downward;

[0030] Since the magnetic end of the electro-controlled magnet is single-sided, two electro-controlled magnets 3B are provided, and the execution end of one of them is arranged to the side away from the upper pressure claw, and the execution end of the other is arranged downward, so as to maintain that the magnetic attraction unit 3 can magnetically fix the workpiece with the horizontal connection surface and the workpiece with the vertical connection surface.

[0031] Embodiment 4

[0032] like Figure 5-7 As shown, the technical feature of the fourth embodiment differs from the third embodiment in that a motor 5 is installed at one end of the upper pressing claw away from the mounting bracket, and the execution end of the motor 5 penetrates the outer wall of the upper pressing claw 2 and is transmission-connected with the mounting bracket 4;

[0033] When the vertical connection surface of the workpiece is small and the magnetic unit 3 with the execution end facing the workpiece cannot be magnetically fixed with the connection surface of the workpiece, the execution end of the motor 5 drives the bracket 4 to rotate 180°, so that the magnetic unit 3 with the execution end facing the workpiece rotates downward, so that the magnetic unit 3 with the execution end facing the workpiece can be magnetically fixed, and the workpiece with a smaller vertical connection surface can be fixed.

[0034] The main body adopted by the utility model has the same structure as that adopted by the upper and lower pressing and rotating mechanism of the U-shaped feeding device of a bending machine with the publication number CN213530533U and the patent name, which is the prior art and will not be described in detail here.

[0035] The bending process adopted by the utility model is the same as the bending process adopted by the patent application with publication number CN209379700U and patent name of a multi-axis driven bending machine, which is already the prior art and will not be described in detail here.

[0036] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
