Several definitions that apply throughout this disclosure will now be presented.
The term “substantially” is defined to be essentially conforming to the particular dimension, shape or other word that substantially modifies, such that the component need not be exact. For example, substantially cylindrical means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising,” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like.
FIG. 1 illustrates an embodiment of a pressing apparatus 100 including a platform 10, a driving device 20, and a pressing structure 30. In at least one embodiment, the pressing apparatus 100 is a stamp press apparatus configured to press a workpiece 19 (shown in FIG. 4) to form the workpiece 19 into a stamped shape.
The platform 10 defines a through hole 11. The platform 10 includes a mounting portion 13, a supporting portion 15 and a first die 19 mounted on the supporting portion 15. The mounting portion 13 and the supporting portion 15 are located at two opposite sides of the through hole 11. In at least one embodiment, the mounting portion 13 is a slot, the supporting portion 15 protrudes from a top surface of the platform 10.
The pressing structure 30 includes a movable support 40 and a roller mechanism 50. The movable support 40 includes a base plate 41 and a mounting plate 43 perpendicularly connected to the base plate 41. The base plate 41 is mounted to the driving device 20. Two lugs 431 extend from a top end of the mounting plate 43. Each lug 431 defines a mounting hole 433. The mounting plate 43 defines two mounting slots 435 located between the two lugs 431.
The roller mechanism 50 includes a limiting block 60 and a pressing member 70. The limiting block 60 includes a first guiding surface 61 and a second guiding surface 63 connected to the first guiding surface 61. The first guiding surface 61 is an inclined plane. An obtuse angle is defined between the first guiding surface 61 and the second guiding surface 63. The pressing member 70 includes a pressing block 71, a shaft 73, a resilient member 75 mounted to the shaft 73, and a second die 79 mounted on the pressing block 71. The pressing block 71 defines a receiving slot 711. The pressing member 70 further includes a roller assembly 77. The roller assembly 77 includes a mounting base 771 mounted on the pressing block 71 and a roller 773 mounted to the mounting base 771. The roller assembly 77 and the second die 79 are located at two opposite sides of the pressing block 71.
FIG. 2 illustrates that the shaft 73 is mounted in the pressing block 71 and protrudes from two opposite sides of the pressing block 71. The resilient member 75 includes a second resilient arm 753 and a first resilient arm 751 received in the receiving slot 711. In at least one embodiment, the resilient member 75 is a coil spring.
FIGS. 3-5 illustrate an assembly of the pressing apparatus 100. The mounting plate 43 of the movable support 40 extends through the through hole 11 from a bottom of the platform 10. The movable support can move in a direction substantially perpendicular to the platform 10. The limiting block 60 is mounted in the mounting portion 13 of the platform 10. The second guiding surface 63 is substantially perpendicular to the platform 10. The shaft 73 is engaged in the mounting hole 433 so that the pressing member 70 is pivotally mounted to the movable support 40. The second resilient arm 753 is received in the mounting slot 435 of the mounting plate 43. The roller 773 abut against the first guiding surface 61. The pressing block 77 and the driving device 20 are located at two opposite sides of the platform 10. An obtuse angle is defined between the pressing block 71 and the mounting plate 43. The pressing block 71 is in a first position.
The workpiece 80 is placed on the supporting portion 15 of the platform 10 and located between the first die 19 and the second die 79. The driving device 20 starts to move the movable support 40 in the direction substantially perpendicular to the platform 10. In at least one embodiment, the movable support 40 moves downward. The roller 773 slides along the first guiding surface 61 to push the pressing block 71 to rotate. An angle between the pressing block 71 and the mounting plate 43 is decreased, and the resilient member 75 is elastically deformed by pressure by the pressing block 71. When the roller 773 slides to the second guiding surface 63, the pressing block 71 is substantially perpendicular to the mounting plate 43 and parallel to the platform 10. The pressing block 71 is in a second position.
The movable support 40 is moved in the direction perpendicular to the platform 10 by the driving device 20 till the pressing block 71 presses the workpiece 80, and the second die 79 is engaged with the first die 19 to form the workpiece 80 into a stamped shape.
The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a pressing apparatus. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, especially in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
