Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of stamping dies, in particular to a multi-station transfer die. Background Technique
[0002] As an important metal processing method, stamping forming has many advantages. Stamping forming can obtain parts with thin walls, light weight, good rigidity, high surface quality and complex shapes that cannot be manufactured or are difficult to manufacture by other processing methods. At present, stamping parts with complex shapes need to be processed step by step. For example, to complete a stamping part of a lid, three different stamping dies are required, then three stamping presses need to be set up, and each machine tool needs to be equipped with an employee. There are problems such as inconsistent processing quality, more labor and low production efficiency, and urgent improvement is needed. Therefore, we propose a multi-station transfer die. Content of the Utility Model
[0003] The purpose of the utility model is to provide a multi-station transfer die to solve the problems raised in the background technique.
[0004] To achieve the above purpose, the utility model provides the following technical scheme: A multi-station transfer die includes an upper die base, a lower die base, a forming die, a necking die and a dotting die. The lower dies of the forming die, the necking die and the dotting die are all fixed on the upper surface of the lower die base, and the upper dies of the forming die, the necking die and the dotting die are all fixed on the lower surface of the upper die base.
[0005] Further, the forming die includes a forming convex block on the lower die and a forming groove on the upper die. The forming convex block is vertically aligned with the forming groove, and the forming groove is in the shape of a double-layer circular cover with a smaller diameter on the upper layer and a larger diameter on the lower layer.
[0006] Further, the necking die includes a necking convex block on the lower die and a necking groove on the upper die.
[0007] Further, the dotting die includes a dotting convex block on the lower die and a dotting groove on the upper die. The dotting groove includes a double-layer circular cover groove with a smaller diameter on the upper layer and a larger diameter on the lower layer. Concave holes for forming convex points are provided on the inner wall of the cover groove on the lower layer of the dotting groove. The dotting convex block includes a double-layer tower column with a smaller diameter on the upper layer and a larger diameter on the lower layer. A convex body for forming convex points is provided on the outer wall of the tower column on the lower layer of the dotting convex block.
[0008] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0009] The technical solution of this application concentrates the forming die, the necking die and the dotting die on one stamping press. Only one employee is needed to gradually complete the three stamping operations of the product. Traditionally, three people are required to operate three stamping machine tools respectively to process three stamping operations, solving the problems of more labor and low production efficiency, improving production efficiency, reducing labor costs and improving quality stability. Description of the Drawings
[0010] Other features, objects, and advantages of the present utility model will become more apparent from the following detailed description of non - restrictive embodiments read in conjunction with the accompanying drawings:

[0013] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.
[0014] Embodiment 1, as Figure 1 shown, the present utility model provides a technical solution: a multi - station transfer die, including an upper die base 1, a lower die base 2, a forming die 3, a necking die 4, and a dotting die 5. The lower dies of the forming die 3, the necking die 4, and the dotting die 5 are all fixed on the upper surface of the lower die base 2, and the upper dies of the forming die 3, the necking die 4, and the dotting die 5 are all fixed on the lower surface of the upper die base 1.
[0015] In a specific embodiment of the present utility model, the forming die 3, the necking die 4, and the dotting die 5 are arranged at equal intervals from right to left. The lower dies of the forming die 3, the necking die 4, and the dotting die 5 are all fixed on the upper surface of the lower die base 2, and the upper dies of the forming die 3, the necking die 4, and the dotting die 5 are all fixed on the lower surface of the upper die base 1. Subsequently, the lower die base 2 and the upper die base 1 are installed on a punching press. The punching press drives the upper die base 1 to approach the lower die base 2 through a hydraulic mechanism. The workpieces are sequentially placed into the forming die 3, the necking die 4, and the dotting die 5 to sequentially complete the processes of preliminary forming, bottom necking, and dotting on the outer surface of the bottom layer. The forming groove of the forming die 3 has a double - layer circular cover shape with a smaller upper - layer diameter and a larger lower - layer diameter. The punching press is equipped with a manipulator, which manipulates the manipulator to place the blank 7 on the surface of the forming groove of the forming die 3. Using the stamping function of the punching press, the forming die 3 can form the blank 7 into a double - layer circular cover shape. Subsequently, the preliminarily formed double - layer circular cover is placed on the necking protrusion of the necking die 4. The necking protrusion as a whole includes a columnar shape stacked up and down. The lower - layer column of the necking protrusion has a retracted shape. When the upper die and the lower die of the necking die 4 are in contact, the bottom layer of the preliminarily formed double - layer circular cover presents a necked shape (as Figure 1(enlarged view), the overall dimensions of the dotting bump and the necking bump of the dotting die 5 are similar. The only difference is that the inner wall of the cover body groove at the lower layer of the dotting groove is provided with a concave hole for forming the convex point, and the outer wall of the tower column at the lower layer of the dotting bump is provided with a convex body for forming the convex point. When the upper die and the lower die of the dotting die 5 are fitted together, convex points are punched out on the outer wall of the double-layer circular cover body (such as Figure 1 (enlarged view), which is convenient for taking the double-layer circular cover body (the final outer shape of the product 6).
[0016] In the preferred technical solution, the forming die 3 includes a forming bump on the lower die and a forming groove on the upper die. The forming bump and the forming groove are vertically aligned. The forming groove is in the shape of a double-layer circular cover body with a smaller diameter in the upper layer and a larger diameter in the lower layer.
[0017] In the preferred technical solution, the necking die 4 includes a necking bump on the lower die and a necking groove on the upper die.
[0018] In the preferred technical solution, the dotting die 5 includes a dotting bump on the lower die and a dotting groove on the upper die. The dotting groove includes a double-layer circular cover body groove with a smaller diameter in the upper layer and a larger diameter in the lower layer. The inner wall of the cover body groove at the lower layer of the dotting groove is provided with a concave hole for forming the convex point. The dotting bump includes a double-layer tower column with a smaller diameter in the upper layer and a larger diameter in the lower layer. The outer wall of the tower column at the lower layer of the dotting bump is provided with a convex body for forming the convex point.
[0019] In summary, by concentrating the forming die, the necking die and the dotting die on a single stamping lathe, only one employee is required to gradually complete the three stamping operations of the product, solving the problems of a large number of workers and low production efficiency, improving production efficiency, reducing labor costs, and improving quality stability.
