Description

Technical Field

[0001] The utility model relates to the technical field of processing equipment, in particular to a punching device for processing a lock piece. Background Art

[0002] The locking plate is an accessory for preventing the nut from loosening. Structurally, it consists of a ring-shaped main body and multiple external ears on the outer ring of the main body, and there is a certain angle between the external ears and the main body. Refer to the specification of this application Figure 8 The processing technology of this lock piece is usually through a punching process. After the overall structure is processed, the outer ear is bent axially at a certain angle by a stamping process. It requires two processes and the efficiency needs to be improved. Utility Model Content

[0003] The utility model aims to provide a punching device for processing a lock piece, which can reduce the processing steps of the lock piece and improve the working efficiency.

[0004] Specifically, the utility model provides a punching device for processing a lock plate, which is provided with an upper template and a lower template, and a material strip passes through the upper template and the lower template, and a punching tool and a two-in-one punching and stamping tool are sequentially provided below the upper template along the forward direction of the material strip, and a notch corresponding to the punching tool and a forming opening corresponding to the punching and stamping tool are provided on the lower template; the shape of the notch matches the punching tool, and the shape of the punching tool matches the shape of the internal circular hole and the external notch of the lock plate, and when the punching tool moves downward under downward pressure and cooperates with the notch, the waste material can be separated from the material strip, leaving the required main body part and outer ear part of the lock plate; after the material strip advances to the position of the punching and stamping tool, the punching and stamping tool moves downward and cooperates with the forming opening, and the two-in-one punching and stamping tool can separate the main body part and the outer ear part of the lock plate from the material strip as a whole, and then the outer ear is bent by punching to obtain a complete product.

[0005] Furthermore, the punching and stamping tool includes an annular punching tool fixed on the upper template, and a punching tool movably arranged in the annular punching tool. The bottom of the punching tool is in the shape of a cone, and the forming opening is a circular through-opening. Two movably arranged supporting bases are provided in the forming opening. The supporting base is below the upper opening of the through-opening. The supporting base has an inclined surface that matches the punching tool. The annular punching tool cooperates with the through-opening downward under downward pressure to separate the main body of the locking plate and the outer ear part as a whole from the material belt, and after separation, they fall on the supporting base below the through-opening. Subsequently, the punching tool in the punching tool continues to press downward, and cooperates with the supporting base to bend the outer ear part to obtain a complete product. After the bending is completed, the supporting base is withdrawn, allowing the product to fall along the through-opening to the conveyor belt or material frame arranged below the lower template.

[0006] Furthermore, the upper template includes an upper clamp and a lower clamp. The top of the lower clamp is provided with two countersunk holes. The punching tool and the blanking tool can be installed in the two countersunk holes. The top periphery of the punching tool and the blanking tool is provided with a flange which cooperates with the large hole of the countersunk hole so as to be fixed in the countersunk hole. At the same time, the upper clamp is connected to the top of the lower clamp by bolts to provide support and fixation for the top of the punching tool and the blanking tool. The advantage of this design is that it is convenient to replace the punching tool and the blanking tool. When replacing, you only need to remove the bolts of the upper clamp, then you can remove the lower clamp, and then remove the punching tool and the blanking tool for replacement.

[0007] Furthermore, the upper clamp is fixed on a plurality of upright guide columns arranged on the lower template, a top plate is provided at the top of the plurality of guide columns, a first cylinder is provided on the top plate, a telescopic rod of the first cylinder is connected to the upper clamp, and the first cylinder can drive the upper clamp to rise and fall vertically along the guide columns, thereby providing downward pressure for the punching tool and the shearing tool.

[0008] Furthermore, a second cylinder is installed on the upper clamping plate, and the telescopic rod of the second cylinder is connected to the punching tool installed inside the punching tool. Its function is to drive the punching tool to press down again to bend the outer ear part after punching.

[0009] Furthermore, the lower template includes a base and a lower template body. The base is used to carry and install the guide column. The recess and the forming port are both arranged on the lower template body. A third cylinder is respectively provided on both sides of the lower template body and is connected to the movably arranged bearing base, which is used to drive the supporting base to move. After the stamping is completed, the supporting base is removed so that the product can fall along the through-port.

[0010] Beneficial effects: The utility model can separate waste materials from the material strip through a punching tool, and then use a blanking and stamping tool to separate the main body of the lock plate and the outer ear part as a whole from the material strip, and then punch to bend the outer ear to obtain a complete product. Compared with the existing technology, it has fewer steps and can be directly formed on the blanking device for lock plate processing, which effectively improves efficiency.
