Description

Technical Field

[0001] The utility model relates to the field of stamping dies for synchronously ejecting parts, in particular to an inclined wedge pushing part structure in a continuous die. Background Art

[0002] In the actual production of progressive molds, it is often the case that the product remains on the mold after being cut off. Therefore, when designing the mold, it is necessary to consider pushing the product out of the mold. The common push-out structure is to use a cylinder push-out structure. However, the disadvantage of the cylinder push-out is that it is difficult to keep the cylinder and the punch press synchronized during high-speed stamping operations. If they are not synchronized, the mold will be damaged.

[0003] For example, the utility model patent with publication number CN201969777U discloses a stamping production equipment for processing U-shaped or π-shaped beams, including a forming device, a side forming device, a side punching device, a power transmission system and a control system. The forming device includes a machine tool bed, a workbench and a stamping die. The stamping die is arranged on the workbench, and the workbench is respectively connected to the power transmission system and the control system. The forming device also includes a pushing component for conveying the processed workpiece to the conveyor belt. The pushing component includes a side push cylinder for pushing the workpiece away from the workstation and a push-up component for lifting the workpiece. The side push cylinder is respectively connected to the power transmission system and the control system. The stamping die is provided with an accommodating hole for accommodating the push-up component below the workpiece. The side push cylinder is arranged on the workbench. The side push cylinder includes a horizontal ejection cylinder, which is arranged parallel to the workbench, and a horizontal push block is connected to the front end of the horizontal ejection cylinder. The push operation and push operation of the stamping equipment use two systems. It is difficult to coordinate the control system to achieve synchronous operation, and it is difficult to adapt to the working conditions of high-speed stamping operations of continuous molds.

[0004] The utility model solves the above problems with a simple inclined wedge structure. Utility Model Content

[0005] The utility model aims to provide an inclined wedge pusher structure in a continuous die to solve the problem of asynchronism between a punch press and a pusher structure in high-speed punching operation.

[0006] In order to solve the above problems, the technical solution adopted is: a structure of an inclined wedge pusher in a continuous die, including an upper die seat, an inclined wedge fixed below the upper die seat, a product pusher block movably connected to the inclined wedge through a roller, a pusher block pressing block, a concave mold plate below the product pusher block, and a product baffle installed on the concave mold plate, the lower part of the inclined wedge is provided with a long strip groove, the lower part of the groove is bent toward the product side, and the front and rear widths of the groove are consistent with the diameter of the roller; the front part of the pusher block pressing block is fixedly connected to the product pusher block, and the rear part is pressed against the rear inclined wedge. The up and down movement of the inclined wedge can drive the product pusher block to move forward and backward to complete the pusher operation.

[0007] As a further improvement, a material drop hole is provided in front of the product pushing block, and the product blocking piece is located above the material drop hole.

[0008] Specifically, the upper edge of the drop hole is higher than the lower surface of the product pushing block.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The utility model can realize synchronous completion of the pushing operation and the stamping operation, thus avoiding damage to the stamping die, and has a simple and practical structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The utility model will be further explained and illustrated below in conjunction with embodiments.

[0017] Example: See Figure 1-4, a structure of an inclined wedge pusher in a continuous die, comprising an upper die seat 1, an inclined wedge 2 fixed below the upper die seat 1, a product pusher 5 movably connected to the inclined wedge 2 through a roller 3, a pusher block pressing block 4, a concave plate 8 below the product pusher 5, a product baffle 7 installed on the concave plate 8, and a lower die seat 9 fixed below the concave plate 8, wherein a long strip groove is provided at the lower part of the inclined wedge 2, the lower part of the groove is bent toward the product side, and the front and rear widths of the groove are consistent with the diameter of the roller 3; the rolling of the roller 3 in the groove of the inclined wedge 2 drives the product pusher 5 to move forward and backward; the front part of the pusher block pressing block 4 is fixedly connected to the product pusher 5, and the rear part is pressed against the rear inclined wedge 2. A blanking hole is provided in front of the product pusher 5, and the product baffle 7 is located above the blanking hole to limit the blanking position of the product 6. The upper edge of the blanking hole is higher than the lower surface of the product pusher 5. The stamping assembly (not shown) of the continuous die is fixed below the upper die seat 1 and directly above the product.

[0018] like Figure 2 and 3 As shown, during operation, when the upper die moves downward to the bottom dead point, the roller 3 is located at the upper end of the groove of the inclined wedge 2. At this time, through the transmission of the push block and the pressure block 4, the product push block 5 retracts backward so that the stamping assembly can complete the stamping operation of the product 6; after the stamping is completed, when the upper die moves upward to the top dead point, the roller 3 is located at the lower end of the groove of the inclined wedge 2. At this time, through the transmission of the push block and the pressure block 4, the product push block 5 pushes the product 6 forward into the blanking hole.
