Description

Technical Field

[0001] This utility model relates to the field of sheet metal shearing technology, and more specifically, it relates to a sheet metal anti-warping clamping device for a shearing machine. Background Technology

[0002] In the field of sheet metal processing, shearing machines, as a key cutting equipment, are widely used in the cutting of various types of sheets. Their core function is to precisely cut the sheet metal into the required specifications according to preset dimensions to meet the needs of different industrial production scenarios. However, in actual shearing production, existing shearing machine technology faces a critical problem that urgently needs to be solved: inconsistent cuts caused by the bending of the sheet metal during the shearing process.

[0003] Currently, shearing equipment on the market inevitably subjectes sheet metal to various external forces and its own weight during production, transportation, and storage, resulting in varying degrees of bending deformation. When such bent sheet metal is fed into a shearing machine, stress concentration occurs at the bent areas under the shearing force. This stress concentration causes localized micro-displacement and deformation of the sheet metal during shearing, preventing the shearing machine blades from precisely cutting the sheet metal along the predetermined straight trajectory. Ultimately, this results in uneven, wavy, or other inconsistent cuts on the sheared sheet metal.

[0004] Inconsistent cuts not only prevent the cut sheets from meeting the requirements of high-precision processing, but also increase subsequent correction processes and costs, and reduce production efficiency. Utility Model Content

[0017] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0019] Please see Figure 1-6 The present invention provides the following technical solution: Example 1: To solve the problem of inconsistent cuts caused by bending of the board material during the shearing process.

[0020] The machine includes a housing 1, a feeding rack 2 located beside the housing 1, a feeding device 3 located on top of the feeding rack 2, and a shearing device 4 located on top of the housing 1. The anti-warping pressing device for the shearing machine also includes a rotating abutment pressing mechanism 5. The rotating abutment pressing mechanism 5 is located beside the shearing device 4. The rotating abutment pressing mechanism 5 includes a first movable material placement part 51, a rotating part 52, and a rotating abutment part 53. The first movable material placement part 51 has multiple parts and is slidably disposed on top of the feeding rack 2, and all of the multiple first movable material placement parts 51 are used to carry the sheet metal to be sheared. The rotating part 52 has a pair and is slidably disposed on both sides of the housing 1, and both of the rotating parts 52 are located beside the shearing device 4. The rotating abutment part 53 is rotatably disposed between the pair of rotating parts 52, and the rotating abutment part 53 is used to abut and convey the sheet metal to be sheared.

[0021] In this embodiment, the rotating part 52 is preferably a multi-stage telescopic cylinder. When the multi-stage telescopic cylinder is activated, it drives the rotating abutment part 53 to translate until the rotating abutment part 53 comes into contact with the sheet metal to be sheared carried on the top of the first movable feeding plate. After contact, the rotating abutment part 53 enters a rotating state. The first movable feeding plate can drive the sheet metal to be sheared to move linearly closer to or further away from the shearing device 4. Under the synergistic action of the first movable feeding plate and the rotating abutment part 53, targeted compression can be applied to the bent parts of the sheet metal to be sheared. This compression process does not affect the continuous conveying of the sheet metal. It solves the problem of inconsistent cuts during shearing caused by the bending deformation of the sheet metal to be sheared, and achieves the effect of reducing material waste caused by the bending deformation of the sheet metal.

[0022] See Figures 4-6 The rotary abutment and pressing mechanism 5 also includes a mounting bracket 54, a first vertical guide rail 55, a first vertical slider 56, and a rotary cylinder 57; the mounting bracket 54 is a pair and is respectively disposed on the side of the housing 1; the first vertical guide rail 55 is a pair and is respectively disposed on the side of the pair of mounting brackets 54; the first vertical slider 56 is a pair and is respectively slidably disposed on the side of the pair of first vertical guide rails 55; the rotary cylinder 57 is a pair and is respectively disposed on the side of the pair of first vertical sliders 56, and the end faces of the pair of rotary cylinders 57 are fixedly connected to the rotating part 52.

[0023] To drive the rotating part 52 to descend and rotate so that the rotating abutment part 53 can press and crush the sheet material to be sheared, the first vertical slider 56 can rise or fall on the first vertical guide rail 55. When the first vertical slider 56 moves, it can drive the rotating cylinder 57 and the rotating part 52 to move synchronously. In this embodiment, when the rotating cylinder 57 is started, it can drive the rotating part 52 to rotate, thereby enabling the rotating part 52 and the rotating abutment part 53 to perform a rotating tilting motion centered on the rotating cylinder 57. Thus, the sheet material to be sheared can be targeted and stably conveyed during the conveying stage of the feeding rack 2 and the shearing stage of the shearing device 4.

[0024] See Figures 3-6 The rotary abutment clamping mechanism 5 also includes a rotary driver 58; the rotary driver 58 is disposed on the side of the rotating part 52, and the output end of the rotary driver 58 is connected to the input end of the rotary abutment part 53. When the rotary driver 58 is started, it can drive the rotary abutment part 53 to rotate.

[0025] The rotary driver 58 is preferably a servo motor. When the rotary driver 58 is started, it can drive the rotary abutment part 53 to rotate and transport the plate. When it is necessary to squeeze and flatten the bent part of the plate, the rotary driver 58 is started, and the first moving material placement part 51 and the rotary abutment part 53 cooperate with each other so that the rotary abutment part 53 can repeatedly squeeze the plate according to the degree of bending.

[0026] See Figure 6 The rotary abutment clamping mechanism 5 also includes a first linear driver 59 and a rotating rod 591; the first linear driver 59 has a pair and is respectively disposed on the top of the first vertical guide rail 55; the rotating rod 591 has a pair and is respectively rotatably disposed on the side of the first vertical guide rail 55, and the input ends of the pair of rotating rods 591 are respectively connected to the output ends of the pair of first linear drivers 59.

[0027] In this embodiment, the first linear driver 59 is preferably a servo motor, and the rotating rod 591 is preferably a ball screw. When the first linear driver 59 is started, it can drive the rotating rod 591 to rotate, and then when the rotating rod 591 rotates, it can drive the first vertical slider 56 to move.

[0028] See Figure 5The rotary abutment and pressing mechanism 5 also includes a first horizontal guide rail 592 and a lead screw 593; there are multiple first horizontal guide rails 592 and they are respectively arranged at the bottom of the feeding frame 2, and the multiple first horizontal guide rails 592 are all located below the first movable material placement part 51; there are multiple lead screws 593 and they are respectively rotatably arranged at the top of the first horizontal guide rails 592, and the lead screws 593 are respectively threadedly connected to the first movable material placement part 51. When the lead screw 593 is activated, it can drive the first movable material placement part 51 to move.

[0029] In this embodiment, a servo motor for driving the lead screw 593 to rotate is provided on the side of the first horizontal guide rail 592. When the servo motor is started, it can drive the lead screw 593 to rotate. When the lead screw 593 rotates, it can drive the first moving material placement part 51 to move.
