DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The embodiments of the present application are:

[0019] See alsoFigures 1-3 , Figure 1 This is a schematic diagram of the overall structure of the waste cutting mechanism for a stamping die of the utility model. Figure 2 This is a structural diagram of the support frame 105 and the sliding sleeve 106 of the present invention. Figure 3 It is a structural schematic diagram of the driving component of the utility model.

[0020] The waste cutting mechanism for stamping dies of the present invention includes a workbench 101, a material 102, a cutter body 103, a lifting frame 104, a support frame 105, a sliding sleeve 106, a connecting rod 107, a frame 108, a shaft 109, a contact wheel 110, a limiting groove 111, a limiting protrusion 112, a connecting sleeve 113, a drive motor 114, a drive screw 115, a bearing bracket 116, and a controller 117. This solves the problem in the prior art that, due to the lack of a centering positioning mechanism, the material is easily displaced in the width direction during transportation, resulting in the clamping plate being unable to properly clamp the material and the cutter being unable to accurately cut. It is understandable that the above solution can also be used to ensure cutting quality.

[0021] In this embodiment, the workbench 101, the cutter body 103 and the lifting frame 104 are all existing technologies. The specific structure refers to the existing technology CN217889203U, which is an integrated stamping die for trimming and waste cutting. It is installed on the workbench 101 through the positioning component, thereby solving the problem that the existing technology does not have a centering positioning mechanism, and the material is easily displaced in the width direction during the transportation process, resulting in the splint being unable to clamp the material normally and the cutter being unable to cut accurately.

[0022] The support frame 105 is fixedly connected to the workbench 101 and is located on a side of the workbench 101 close to the cutter body 103. The sliding sleeve 106 is sleeved on the support frame 105 and is slidably connected to the support frame 105. The connecting rod 107 is fixedly connected to the sliding sleeve 106 and is located on one side of the sliding sleeve 106. The frame 108 is fixedly connected to the connecting rod 107 and is located at an end of the connecting rod 107 away from the sliding sleeve 106. The shaft 10 9 is fixedly connected to the frame 108 and is located in the frame 108. The contact wheel 110 is sleeved on the outside of the shaft 109 and is rotatably connected to the shaft 109. The driving member drives the sliding sleeve 106 to move. The support frame 105 is a door-shaped frame. The cross bar in the middle of the support frame 105 is a cylinder. The number of the sliding sleeves 106 is two and is sleeved on the support frame 105. It can slide freely on the support frame 105. The connecting rod 107 is used to connect the frame 10 8 is connected to the sliding sleeve 106 so that the frame 108 moves with the movement of the sliding sleeve 106. The frame 108 is L-shaped and has two members, which are respectively connected to the two connecting rods 107. The shaft rods 109 are multiple and evenly arranged in the two frames 108. The number of the contact wheels 110 matches the number of the shaft rods 109. The contact wheels 110 are mounted on the shaft rods 109 through bearings and can rotate freely. The contact wheels 110 are used to contact both sides of the material 102. The driving member is used to drive the sliding sleeve 106 to move. The movement of the sliding sleeve 106 drives the contact wheels 110 to contact the side surfaces of the material 102. The contact wheels 110 on both sides push the material 102 to move toward the center, thereby realizing the centering of the material 102. This solves the problem that the prior art lacks a centering positioning mechanism, and the material is easily displaced in the width direction during transportation, resulting in the splint being unable to clamp the material normally and the cutter being unable to cut accurately.

[0023] Secondly, the limiting groove 111 is located on the side of the support frame 105 close to the sliding sleeve 106; the limiting protrusion 112 cooperates with the limiting groove 111, and the limiting groove 111 is opened along the length direction of the support frame 105. The limiting protrusion 112 is located on the inner wall of the sliding sleeve 106. Through the cooperation between the limiting protrusion 112 and the limiting groove 111, the sliding sleeve 106 is limited to avoid the sliding sleeve 106 from rotating, causing the contact wheel 110 to shift.

[0024] At the same time, the connecting sleeve 113 is fixedly connected to the sliding sleeve 106 and is located on the side of the sliding sleeve 106 away from the connecting rod 107; the driving motor 114 is installed on the support frame 105 and is located on the side of the support frame 105 close to the connecting sleeve 113; the driving screw 115 is fixedly connected to the output shaft of the driving motor 114 and is threadedly connected to the connecting sleeve 113. There are two connecting sleeves 113, which are respectively arranged on the top of the two sliding sleeves 106. The connecting sleeve 113 has a threaded through hole. The driving screw 115 is a bidirectional screw with opposite thread directions at both ends. The two connecting sleeves 113 are respectively sleeved on both ends of the driving screw 115. The driving motor 114 is fixed to the support frame 105 by bolts for driving the driving screw 115 to rotate. The driving screw 115 is driven to rotate by the driving motor 114, thereby driving the two connecting sleeves 113 to move synchronously in opposite directions.

[0025] In addition, the bearing bracket 116 is fixedly connected to the support frame 105 and is rotatably connected to the drive screw 115. There are two bearing brackets 116, which are respectively located at both ends of the drive screw 115. A bearing is provided inside the bearing bracket 116. The drive screw 115 passes through the bearing bracket 116 and is fixedly connected to the inner ring of the bearing. Through the bearing bracket 116, the drive screw 115 is stably supported.

[0026] Finally, the controller 117 is installed on the workbench 101, the drive motor 114 is electrically connected to the controller 117, and the controller 117 is matched with the model of the drive motor 114. The controller 117 can achieve high-precision position control, speed control and forward and reverse control. By setting the controller 117, the drive motor 114 can be driven to perform regular forward and reverse rotation.

[0027] In this embodiment, during use, the controller 117 controls the drive motor 114 to rotate forward and reverse regularly according to a set program, and the drive screw 115 rotates accordingly, driving the two sliding sleeves 106 to continuously move closer and farther away. The material 102 passes between the contact wheels 110 on both sides. The contact wheels 110 on both sides move with the movement of the sliding sleeves 106, continuously pushing the material 102 toward the center from both sides, thereby achieving the centering of the material 102 and ensuring that the lifting frame 104 can accurately cut when driving the cutter body 103. The present application uses the contact wheels 110 on both sides to push the material 102 toward the center, thereby achieving the centering of the material 102. This solves the problem in the prior art that, due to the lack of a centering positioning mechanism, the material is easily displaced in the width direction during transportation, resulting in the clamping plate being unable to properly clamp the material and the cutter being unable to accurately cut.

[0028] The above disclosure is merely one or more preferred embodiments of the present application and is not intended to limit the scope of the present application. A person skilled in the art will understand that all or part of the processes of the above embodiments and equivalent changes made in accordance with the claims of the present application are still within the scope of the present application.
