Description

Edge Trimming Machines for Thin Sheet Plastic Parts

technical field

The utility model relates to an edge trimming machine.

Background technique

Existing sheet plastic parts that rely on extrusion mostly have burrs, and most of them use scissors to remove burrs manually, so the removal of burrs often consumes a lot of manpower and material resources, which limits the rapid processing of parts and reduces the processing efficiency of parts. Efficiency, affecting the quality of parts. The removal of its burrs seriously restricts the mass production of parts and affects the benefits of enterprises.

General trimming machines all need clamping device, and the cutting device completes the function of deburring in turn, and the mechanical structure is relatively complicated.

Contents of the invention

In order to overcome the deficiencies of manual operation and low processing efficiency of the existing thin-sheet plastic parts trimming method, the utility model provides a thin-sheet plastic part edge trimming machine with mechanized operation and high processing efficiency.

The technical scheme that the utility model solves its technical problem adopts is:

A trimming machine for sheet plastic parts, comprising a base, a workpiece lower mold, a workpiece upper mold, a tool and an operating handle; the workpiece lower mold is installed on the base, and the workpiece upper mold is located above the workpiece lower mold , the trimming machine also includes a first spring, a second spring, a first nut, a second nut, a first connecting piece and a second connecting piece; the workpiece upper mold is located below the tool, and the workpiece upper mold can It is fitted in the middle groove of the tool by moving up and down, the straight rod section of the first nut passes through the tool and is fixed on the upper mold of the workpiece, and one end of the first spring is fixedly connected with the lower surface of the first nut. The other end of the first spring is fixedly connected with the upper surface of the tool, the straight rod section of the second nut passes through the tool and is fixed on the upper mold of the workpiece, and one end of the second spring is connected with the lower surface of the second nut. The other end is fixedly connected to the upper surface of the tool; the first connecting piece is fixedly connected to the tool, and the shaft of the first connecting piece is located in the limit hole slot of the operating handle. The end of the handle is rotatably mounted on a second link fixed to the base.

The beneficial effects of the utility model are mainly manifested in that the utility model is light in weight, small in size, simple in operation, can quickly remove burrs of sheet parts, and is suitable for different environments.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

According to Figure 1 and Figure 2, a trimming machine for sheet plastic parts includes a base 2, a workpiece lower die 3, a workpiece upper die 4, a first spring 5, a second spring 6, a first nut 7, and a second nut 8. Tool 9, first connecting piece 10, second connecting piece 11 and operating handle 12;

The base 2 and the workpiece lower mold 3 are fixed by screws, the workpiece upper mold 4 is located below the cutter 9, and the workpiece upper mold 4 can move up and down and is set in the middle groove of the cutter 9. The first The straight rod section of the nut passes through the tool and is fixed on the workpiece upper mold 4, one end of the first spring 5 is fixedly connected with the lower surface of the first nut 7, and the other end is fixedly connected with the upper surface of the tool 9, so The straight rod section of the first nut passes through the tool and is fixed on the workpiece upper mold 4, one end of the second spring 6 is fixedly connected with the lower surface of the second nut 8, and the other end is fixed with the upper surface of the tool 9. connected; the first connecting piece 10 is fixed to the upper surface of the tool 9 by screws, and the second connecting piece 11 is fixed to the workpiece upper mold 4 by screws; the operating handle 12 can be wound around the second The shaft on the connecting piece 11 rotates and confines the shaft on the first connecting piece in the hole on the handle 12 .

The working process of this embodiment is as follows: the operator places the workpiece 13 in a limited position on the workpiece lower mold 3, and in the process of pressing the operating handle 12 by hand, the workpiece upper mold 4 and the tool 9 are pushed by the operating handle, Moving downward, the workpiece upper mold 4 first touches the workpiece, and then under the action of the spring, the workpiece 13 is pressed tightly, and then the tool continues downward, and at the same time cuts off the burrs of the workpiece until the tool contacts the upper surface of the workpiece upper mold 4, The workpiece burr removal action is completed. When the operator lifts the operating handle by hand, the tool 9 rises first, and when the spring rises to the original length, the upper mold 4 of the workpiece starts to rise. When it rises to a certain height, the operator can take out the workpiece. This process is completed. At this time, The lower surface of the upper mold of the workpiece is located under the cutting edge of the tool, preparing for the next pressing, and the trimming machine's working process is completed.

The content described in the embodiments of this specification is only an enumeration of the realization forms of the utility model concept. The protection scope of the utility model should not be regarded as limited to the specific forms stated in the embodiments. The protection scope of the utility model also includes Equivalent technical means that those skilled in the art can think of according to the concept of the utility model.
