Description

A punching die for bending chain plates

technical field

The utility model belongs to the technical field of chain manufacturing, in particular to a blanking die for bending chain plates.

Background technique

At present, some bending chain plates need to be combined with mold blanking first, and then the bending process requires the design of multiple sets of molds, and it takes a lot of time to debug the molds. It not only wastes manpower and material resources, but also has high cost and low production efficiency for end users.

Contents of the invention

In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a punching die for bending chain plates, which integrates blanking and bending during punching, and the punched out chain plates can omit the bending process. Increase productivity.

In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

A blanking die for bending a chain plate includes an upper die and a lower die, the upper die includes a push rod, an insert push rod, a die handle, a die holder, a top plate, a die, punching nails and a ejector, and the die The mold is fixed under the die holder, the die holder is fixed under the handle of the die, the ejector rod is passed through the handle of the die and the lower end can push the push rod of the insert, the top plate is set in the holder of the die and is pushed by the insert. The rod pushes and moves up and down, the ejector is fixed on the die, the punch nail is inserted in the ejector and pushed by the top plate to realize the punching of the chain plate, the ejector has two upper platforms with different heights, The two upper platforms are transitioned through a slope; the lower mold includes a discharge plate, a convex and concave mold, a lower backing plate, and a convex and concave mold fixing seat. The material plate is sleeved outside the convex and concave mold, and the convex and concave mold has two lower platform surfaces corresponding to the two upper platform surfaces of the ejector. The height of the two lower platform surfaces is different and transitions through a slope; The bottom and the top of the male and female dies have a shape corresponding to the bending chain.

Due to the adoption of the above technical scheme, the utility model processes the bending parameters and shape of the required chain plate on the ejector of the mold and the convex and concave dies, so that the required chain plate size can be obtained directly after punching, without further processing. The bending process is performed separately. Through this series of mold design and process improvement, it can be ensured that the bending has been completed while blanking. The bending process is omitted, and the working time of employees can be reduced through this scheme, and the production efficiency can be improved.

Detailed ways

Below in conjunction with accompanying drawing, specific embodiment of the present utility model is described in detail.

Example 1:

As shown in Figure 1 and Figure 2, a punching die for bending chain plates includes an upper die and a lower die, and the upper die includes a push rod 1, an insert push rod 2, a die handle 3, a die holder 4, The top plate 5, the die 6, the punching nail 7 and the ejector 12, the die 6 is fixed under the die holder 4, the die holder 4 is fixed under the die handle 3, and the ejector rod 1 is installed in the die handle 3 And the lower end can push the insert ejector rod 2, the top plate 5 is set in the die holder 4 and is pushed up and down by the insert ejector rod 2, the ejector 12 is fixed on the die 6, and the punching nail 7 is inserted in the In the jacking device 12 and pushed by the top plate 5 to realize chain plate punching, as shown in Figures 3a, 3b, and 3c, the jacking device 12 has two upper platform surfaces with different heights, and these two upper platform surfaces pass through Slope transition; the lower mold includes a discharge plate 8, a convex and concave mold 9, a lower backing plate 10, a convex and concave mold fixing seat 11, the convex and concave mold fixing seat 11 is fixed on the lower backing plate 10, and the convex and concave mold 9 is fixed on the convex and concave mold fixing seat 11, The unloading plate 8 is sleeved on the outside of the punch and die 9, as shown in Figures 3a, 3b, and 3c, the punch and die 9 has two lower platform surfaces corresponding to the two upper platform surfaces of the ejector 12, and the two lower platform surfaces The platforms have different heights and transition through slopes; the bottom of the ejector 12 and the top of the convex and concave mold 9 have shapes corresponding to the bent chain plates.

In this embodiment, the most important thing is to process the bending parameters and shape of the chain plate to be bent on the ejector of the composite mold and the convex and concave dies, so that the required chain plate size can be obtained directly after punching, without the need for separate Carry out the bending process. In the blanking process, as long as it is punched according to the conventional composite die, the ejector and the punch and die cooperate to directly complete the blanking and bending. This bending and punching method saves the turning and bending process on the original basis. , saving processing costs, improving production efficiency and product quality.

It should be emphasized that: the above are only preferred embodiments of the utility model, and are not intended to limit the utility model in any form. Any simple modification, equivalent change and Modifications still belong to the scope of the technical solution of the utility model.
