Conveyor chain pin forming facility
A conveyor chain pin forming facility includes a base, on which are installed a fixed bottom die device, a movable top die device and two movable side die devices. The side die devices are separately installed on two ends of the bottom die device. A metal object is placed inside the bottom die device. By closing the top die device and the side die devices onto the top side and two sides of the bottom die device, the metal object is compressed to form. The component thus formed has a smooth surface without protruded ribs, and the production process can be simplified.
(a) Field of the Invention
The present invention relates to a forming facility having a plurality of dies, each die moves in relation to each other to close or open, and form a conveyor chain pin.
(b) Description of the Prior Art
As shown in
As shown in
As shown in
The pin 16 can be made by press forming and burr cutting, but because of the protruded ribs 18 on the surface of the pin 16, causing wear and tear on other components, the conventional pin 16 is not an ideal component.
SUMMARY OF THE INVENTIONIn view of the shortcoming of the prior art that involves the risk of causing wear on other components, the present invention provide an innovated forming facility for the production of a pin without protruded ribs on its surface.
To achieve the foregoing objectives and performance, the present invention is installed a fixed bottom die device and a movable top die device and side die devices on a base. After a heated metal object is placed inside the bottom die device, the top die device and the side die devices close to the bottom die device, thereby compressing and forming the metal object into a desired pin configuration without protruded ribs on its surface.
A preferred embodiment of the present invention is described hereunder with drawings to illustrate the objectives, performance and configurations of the invention.
BRIEF DESCRIPTION OF THE DRAWINGS

The metal object 70 is then compressed and deformed by the side die devices 60 to fill up the die holes 42, 52 of the top die device 50 and the bottom die device 40, thereby the forming process is completed.
As shown in
Because of the compression method adopted in the foregoing forming facility involves compressing the heated metal object 70, there is no protruded ribs on the surface of the formed pin, as shown in
Alternatively, the metal object 70 without being heated beforehand is compressed to form by the facility disclosed in the present invention, thereby enabling simplified production. Moreover, the facility disclosed herein can be used to make other components than the conveyor chains, such as the carrier member and the connector member.
It is to be understood that the foregoing description relating to the preferred embodiment and design drawings of the present invention shall not be based to restrict the claim of the invention, and that all equivalent art deriving from the foregoing should be included in the following claim.
Claims
1. A conveyor chain pin forming facility, comprising:
- a base;
- a bottom die device fixed to the base having a bottom die hole at a specified location thereof;
- a top die device movably installed onto the base having a top die hole at a specified location thereof, so that the top die device is corresponding to the bottom die device;
- two side die devices separately and movably installed on the base;
- wherein the die hole of the bottom die device serving to accommodate a metal object, the top die device moving toward the bottom die device until the top and bottom die holes are opposite each other, the two side die devices moving toward the top die device and the bottom die device, thereby a heated metal object is compressed to become a desired form by the closing movement of the top die device and the side die devices toward the bottom die device.
2. The conveyor chain pin forming facility of claim 1, wherein when the top die device and the bottom die device are closed, there are openings on two ends thereof, and the side die devices have protrusions that extend into the openings.
