Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for crushing both ends of a corrugated sheet to bring them into close contact.

Conventionally, wavy heat sinks for transformers and heat sinks for the outer periphery of electric motors have been manufactured by casting.

This invention is a device that was invented to eliminate the disadvantages of casting, such as uneven quality, waste of materials, and unsuitability for mass production.
This device is manufactured for the purpose of crushing both ends of a material formed into a corrugated sheet from a sheet material to make them stick together, increasing the rigidity of the corrugated sheet, and making it easier to weld the end faces. Embodiments of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 are diagrams for explaining the configuration of this apparatus, and FIGS. 3 to 9 are process diagrams for explaining the edge crushing of a corrugated plate using the same apparatus.

Reference numeral 1 is a pedestal for the apparatus, and 2 is a box-shaped main body that is installed on the mount 1. 3 is a shilling for moving the main body 2, 4 is a guide for moving the main body 2
to guide the movement of the object on the pedestal 1.

Reference numeral 5 denotes a push-up cylinder attached to the pedestal 1, and its output is enough to correct the position and misalignment without pushing up the corrugated plate.

6 is a male type and is attached to the push-up cylinder 5.

7 is the lid of the main body 2, 8 is a bracket attached to the upper part of the lid 7, 9 is pressed by a presser cylinder, and is attached to the bracket 8, which is located at a position opposite to the upper cylinder 5.

1. A female mold 11 is attached to a presser cylinder 9 facing the male mold 6, and a crushing cylinder 11 is attached to the outside of the main body 2.

12 is installed inside the main body 2 and is guided in the vertical direction by the main body 2 and the lid 7. One side is crushed and attached to the cylinder 1, and the inside of the remaining one is machined into a tapered shape and a projection 12a is formed in the center. This projection 12a is also tapered. - shaped cotter.

Reference numeral 13 denotes a special shaped holder holder, which is installed inside the cotter 12, and one of which is shaped to engage with a portion of the taper of the cotter 12 both on the outside and the inside, and the other one is fitted into the main body 2. The top and bottom of the holder 13 can be moved in the opening/closing direction by the main body 2 and the lid 7, but cannot be moved in the front-back direction. Reference numeral 14 indicates a spring fixed to the inside of the tip of the spring holder 13, 15 is a spring, and 16 is a spring core that penetrates through the main body 2 and is fixed to the spring holder 13.

Therefore, when the crushing cylinder 1 is pushed, the cock 12 moves along the body 2, and as the cock holder 2 moves, the cock holder 13, whose front part is in close contact with the body 2, joins the cock holder 12 in a tapered shape. The edge of the corrugated sheet can be flattened by pinching the side edge of the corrugated sheet with a tip 14 that moves in a direction perpendicular to the cutter 12 and is fixed to the front end of a tip holder 13. However, Figures 3 to 9
We will explain how to flatten the edges of a corrugated sheet according to the process shown in the figure.

In the apparatus configured as described above, when the corrugated plate that has been transferred a predetermined distance on a feeding device (not shown) stops, the main body 2 is moved by the moving cylinder 3 to the center side by a predetermined distance.

Next, the male mold 6 is raised toward the top of the corrugated sheet by the push-up cylinder 5, and the feeding error of the corrugated sheet is accurately corrected, and at the same time, the female mold 6 serves as a core bar when crushing both ends of the corrugated sheet. Next, the female die 10 is lowered by the presser cylinder 9 to press and position the corrugated plate. Next, the crushing cylinder 11 causes the cotter 12 to
moves forward and closes the claw holder 13.
Step 4: Squeeze both ends of the corrugated sheet to make them stick together. Next, the cotter 12 is moved back by the crushing cylinder 11 and the holder 13 is moved back.
One side is opened and the other side is opened by the force of the spring 15. Next, the female mold 10 is raised by the presser cylinder 9, the male mold 6 is lowered by the push-up cylinder 5, the main body 2 is retreated by the moving cylinder 3, and the corrugated plate is sent a predetermined distance by the feeding device. As described above, the present invention accurately corrects the misalignment of the corrugated sheet sent by the male die 6 which is lifted up by the push-up cylinder 5, and is used as a core metal when crushing, and the normal die 10 is lowered by the presser cylinder 9. This device positions the corrugated sheet by pressing it onto a feeding device, and crushes both ends of the corrugated sheet with claws 14 attached to a claw holder 13 via a crusher 12 using a crushing cylinder 11.

Although the present invention is a device for crushing both ends of a corrugated sheet, it is easily possible to crush only one side of the corrugated sheet, and it is also possible to crush only one side of the corrugated sheet. If the holder 13 is small, it can be opened using only the crushing cylinder 1 without using the spring 15.

As described above, in the present invention, it is possible to automatically crush the weave of a corrugated sheet formed into a corrugated shape one after another and make them stick together, and the corrugated heat sink of a transformer, the heat sink of the outer periphery of an electric motor, etc. can be formed with a plate material. Despite this, it is thicker and has increased rigidity, and it is easier to weld the crushed edges of the ends.
It can prevent uneven quality and waste of materials caused by conventional casting,
This allows for appropriate response to mass production of a wide variety of products.
