Abstract

Provided is a cam type press capable of controlling deformation of a flange of a panel in the course of processing the flange, thus reducing deformation such as a crease, or the like, of the flange. The cam type press includes a padding cam installed to be movable in a slope direction. A slider is installed to be movable toward the padding cam, with a process gap into which a portion of a panel is inserted to form a flange between one side of the padding cam and one side of the slider. An adjustment block adjusts the process gap provided between the other side of the padding cam and the other side of the slider.

First claim

What is claimed is:

1 . A cam type press comprising:
a padding cam installed to be movable in a slope direction; and a slider installed to be movable toward the padding cam, wherein a process gap into which a portion of a panel is inserted to process a flange is formed between one side of the padding cam and one side of the slider, and an adjustment block adjusting the process gap is provided between the other side of the padding cam and the other side of the slider.

2 . The cam type press according to claim 1 , wherein a first bending inducing surface is formed at one side of the padding cam, a second bending inducing surface facing the first bending inducing surface is formed at one side of the slider, and the process gap is formed between the first bending inducing surface and the second bending inducing surface.

3 . The cam type press according to claim 2 , wherein the padding cam is configured to be moved in the slope direction by a driver, and the slider is configured to be moved in the slope direction toward the padding cam.

4 . The cam type press according to claim 3 , wherein the panel is supported by a support die, the driver is vertically moved according to a vertical movement of the support die, and as vertical movement power of the driver is transmitted to the padding cam through a transmission unit, the padding cam is moved in the slope direction.

5 . The cam type press according to claim 4 , wherein the transmission unit includes a horizontal movement block moved in a horizontal direction according to a vertical movement of the driver and a slope movement block moved in a slope direction by the horizontal movement block.

6 . The cam type press according to claim 5 , wherein the driver has a first sloped surface and a first vertical surface, and the horizontal movement block has a second sloped surface in contact with the first sloped surface of the driver and a second vertical surface in contact with the first vertical surface of the driver.

7 . The cam type press according to claim 6 , wherein the horizontal movement block has a third sloped surface formed on the opposite side of the second sloped surface, and the slope movement block has a fourth sloped surface in contact with the third sloped surface of the horizontal movement block.

8 . The cam type press according to claim 7 , wherein a wear plate is interposed between the fourth sloped surface of the slope movement block and the third sloped surface of the horizontal movement block.

9 . The cam type press according to claim 8 , wherein the slope movement block has a flange processing part formed to be adjacent to the padding cam, and the flange processing part has a support surface supporting one side of a panel and a first flange processing surface formed to cross the support surface at a predetermined angle.

10 . The cam type press according to claim 9 , wherein the flange processing part protrudes at an angle corresponding to the slope movement direction of the slope movement block, and the padding cam is installed to be movable in the slope direction in the slope movement block.

11 . The cam type press according to claim 10 , wherein the slider is installed to be movable in the slope direction on the opposite side of the padding cam, the slider has a second flange processing surface formed to cross the second bending inducing surface at a predetermined angle, and the second flange processing surface of the slider is formed to correspond to the first flange processing surface of the flange processing part.

12 . The cam type press according to claim 11 , wherein the first flange processing surface of the flange processing part and the second flange processing surface of the slider are formed to be flat in a direction in which the flange is processed.

13 . The cam type press according to claim 10 , wherein the padding cam is elastically supported by at least one gas spring installed within the slope movement block.

14 . The cam type press according to claim 13 , wherein the at least one gas spring has a cylinder and a rod moving forward and backward with respect to the cylinder, the cylinder is fixed to the slope movement block, and an outer end of the rod is configured to press or support the padding cam.

15 . The cam type press according to claim 13 , wherein a stopper is installed on one side of the slope movement block and is configured to regulate a rising position of the padding cam lifted by at least one gas spring to be within a predetermined range.
