Technical Field of the invention

The utility model relates to the field of industrial automation or domestic purposes, in particular to load a spring with minimum applied effort.

Background of the invention

A metal wire spring that functions in a spring mechanism can compress, extend, rotate, slide, pull and exert force when an equal or greater force is applied. A spring mechanism can exert tension, compression or rotational force in a variety of ways. The use of a spring includes but not limited to punching and stamping. Existing spring loaders require effort to be applied directly towards compressing the spring. This causes more effort to be applied extensively and it is less efficient.

Summary of the invention

The present invention provides a spring loading mechanism for application including but not limited to punching and stamping.

The mechanism used in this invention ensures ease of operation. The minimum human effort required to load the spring of the machine is the significance of this mechanism along with its multiple applications.

The invention provides a spring loading mechanism which utilizes minimum human effort for loading the main spring (1 ) to store the energy required for a required operation such as punching or stamping. It comprises of four helical springs of different sizes and materials. Each spring has its own designated function.

The springs collectively enhances the performance of the spring loading operation by making the spring loading operation with less effort. Description of invention

In order to facilitate the understanding of those skilled in the art, the present invention will be described conjunction with the embodiments and the accompanying drawings, and the contents mentioned in the embodiments are not limited to the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 2, the present invention provides a spring loading mechanism for various applications including punching, stamping, which comprises of spring (1 ), that stores the energy required for the application, spring (2), that reacts to the applied effort on the actuating handle (5), spring (3) supports the actuating handle 5 by pushing it towards the linear ratchet (7), pivot rod (10) supports and acts as a pivot point to actuating handle 5, spring 4 pushes the lock 8 towards the linear ratchet (7) and acts as a passive lock which locks into the linear ratchet (7) and holds the position of the center rod (6), the center rod (6) is attached to the tool holder (12), the supporting structure (11) holds all the parts in their respective position.

During working of the present invention, the actuating handle (5) is pulled upwards which allows the inner end of the actuating handle (5) to slip and engage into a successive bottom tooth of the linear ratchet (7). Simultaneously the spring (2) compresses and spring (3) supports the actuating handle (5) by pushing it towards the linear ratchet (7). When the actuating handle is released after the above process, the spring (2) expands and pushes the inner end of the actuating handle (5) upwards. And hence the spring (1) is compressed.

The lock (8) along with spring (4), passively locks the control rod into position each time the control rod changes its position.

The above steps are repeated consecutively until the required energy is stored into spring (1).

Finally, when the lock (8) is released by pulling the lock handle (9) towards the spring (4), the actuating handle (5) is also pushed backwards, releasing it from the linear ratchet (7). The center rod is now freed and the energy stored in the spring (1) is released through the tool holder (12), towards the tools allowing the tool attached into the tool holder (12) to perform the required task.

Further, the invention could be automated by motorizing the actuating handle (5).

FOR EXAMPLE, In reference to the above description of the invention, if the required operation is said to be punching, then a punching tool is attached into the tool holder (12), which delivers the energy obtained from the spring 1 to perform the punching operation.
