Example 1
Referring to fig. 1, in the present embodiment, an automatic hole flanging and demolding mechanism is provided, which includes an upper pad 1000, an upper pressing body 2000, a lower pressing body 3000 and a lower pad 4000 sequentially disposed from top to bottom. Wherein the upper press body 2000 and the lower press body 3000 can move only in a straight direction.
The upper cushion plate 1000 is arranged in parallel with the lower cushion plate 4000, and the upper cushion plate 1000 is positioned right above the lower cushion plate 4000; the upper press body 2000 is located right above the lower press body 3000.
Before hole flanging, the part 8000 to be hole-flanging needs to be fixed between the upper blanking body 2000 and the lower blanking body 3000, and in the hole flanging process, the part 8000 is extruded by the upper blanking body 2000 and the lower blanking body 3000. In order to ensure that the part 8000 will not be deformed and scrapped due to extrusion during the hole flanging process, the upper and lower swage bodies 2000 and 3000 should be matched with the part 8000 to be hole-flanging.
As shown in fig. 2 and 3, for hole flanging, the upper press body 2000 is provided with an upper guide post 2100 slidably penetrating therethrough, and one end of the upper guide post 2100 near the lower press body 3000 is provided with a first hole flanging punch 2110. The upper pad 1000 is located above the upper press body 2000, and when the machine tool is operated, a pressing force perpendicular to the upper pad 1000 is applied, and after the upper pad 1000 receives the pressing force perpendicular to itself, the upper guide column 2100 is then pressed and the lower press body 3000 is pressed.
In this embodiment, the upper guide post 2100 is not perpendicular to the upper pad 1000, and the angle between the upper guide post 2100 and the upper pad 1000 is set according to the hole flanging angle.
Meanwhile, the lower pressing body 3000 is provided with a lower guide column 3100 which can penetrate through the lower pressing body 3000 in a sliding manner, one end, close to the upper pressing body 2000, of the lower guide column 3100 is provided with a first hole flanging die 3110 for flanging by matching with the first hole flanging punch 2110, and a lower backing plate 4000 for pressing the lower guide column 3100 is arranged below the upper pressing body 2000. Wherein the lower guide post 3100 is parallel to the upper guide post 2100.
When the upper guide column 2100 is pressed to the top, the upper guide column 2100 slides in the upper pressing body 2000; when the lower guide column 3100 is pressed to the top, the lower guide column 3100 slides in the lower press body 3000. Since the upper press body 2000 and the lower press body 3000 can only move in the straight direction, both the upper guide post 2100 and the lower guide post 3100 move in parallel during the hole flanging process, and finally the upper guide post 2000 and the lower guide post 3100 are collinear, so that hole flanging is completed.
The first hole-flanging punch 2110 needs to be inserted into the first hole-flanging die 3110 to complete the hole-flanging operation, and since the first hole-flanging punch 2110 and the first hole-flanging die 3110 are respectively provided on the upper guide post 2100 and the lower guide post 3100, the upper guide post 2100 is collinear with the lower guide post 3100 when the first hole-flanging punch 2110 is inserted into the first hole-flanging die 3110.
In the present embodiment, an upper pressure source 1100 for storing energy is provided between the upper pad 1000 and the upper press body 2000. During hole flanging, the distance between the upper pad 1000 and the upper press body 2000 becomes smaller due to the impact of the stamping force, and the upper pressure source 1100 stores energy due to being pressed.
A lower pressure source 4100 for storing energy is provided between the lower pad 4000 and the lower press body 3000. During hole flanging, the distance between the lower pad 4000 and the lower press body 3000 is reduced due to the impact of the stamping force, and the lower pressure source 4100 stores energy due to the extrusion.
Wherein a nitrogen cylinder may be used for both the upper pressure source 1100 and the lower pressure source 4100. In other embodiments, the upper pressure source 1100 and the lower pressure source 4100 may also be other devices with energy storage function, such as springs, etc.
In this embodiment, a balancing piece 5000 is disposed between the upper press body 2000 and the lower press body 3000, and the balancing piece 5000 is used for transmitting pressure and keeping the upper press body 2000 and the lower press body 3000 balanced when moving, so as to ensure that the upper press body 2000 and the lower press body 3000 can only move in the vertical direction. The balance member 5000 may be provided in a column shape or a block shape.
In the present embodiment, the upper press body 2000 and the lower press body 3000 can move only in the vertical direction by the restrictions of the upper pressure source 1100, the lower pressure source 4100, and the balance 5000.
The working principle of the automatic hole flanging demoulding mechanism is as follows:
the upper slider of the machine tool provides a vertical downward punching force and acts on the upper pad 1000, and the upper pad 1000 moves downward after being subjected to the punching force, in which process the upper pad 1000 presses the upper press body 2000, and at the same time, the upper press body 2000 provides a pressure to move the lower press body 3000 downward. The lower guide column 3100 and the first hole flanging die 3110 and the lower pressing body 3000 are relatively moved, and the lower guide column 3100 and the first hole flanging die 3110 are eventually closed by the top of the lower backing plate 4000 and do not move. The upper slider continuously presses the upper pad 1000, so that the lower pressing body 3000 is upset, and at this time, the positioning of the first hole flanging die 3110 is completed. In this process, the pressure source 4100 stores energy due to compression. The upper slide block continues to press, so that the upper base plate 1000 moves downwards, at this time, the upper guide post 2100 and the first hole flanging punch 2110 are relatively moved with the upper material pressing body 2000 due to the pressing of the upper base plate 1000, the first hole flanging punch 2110 is opposite to the first hole flanging die 3110, die assembly is started, and the upper guide post 2100 and the first hole flanging punch 2110 act on the part 8000 to finish hole flanging. During this process, the upper pressure source 1100 also stores energy due to compression. Under the action of the stamping force applied by the machine tool, the upper pressing body 2000 is finally upset, and then hole flanging is completed, and at the moment, the machine tool is also upset.
After hole flanging is completed, the upper slide block moves upwards, the energy stored by the upper pressure source 1100 starts to be released, the upper base plate 1000 is pushed to return, after the upper guide post 2100 and the first hole flanging punch 2110 lose the top pressure of the upper base plate 1000, the upper guide post 2100 and the first hole flanging punch 2110 start to move relatively to the upper material body 2000, the upper guide post 2100 and the first hole flanging punch 2110 return, and die opening starts. After the energy on the upper pressure source 1100 is completely released, the upper guide post 2100 and the first hole punch 2110 are returned to completion, exiting the part 8000. The upper slider continues to move upwards, the energy stored by the lower pressure source 4100 begins to be released, and pushes the lower pressing body 3000 to return, the lower guide column 3100 and the first hole flanging die 3110 and the lower pressing body 3000 generate relative motion, and the lower guide column 3100 and the first hole flanging die 3110 return. After the energy on the lower pressure source 4100 is completely released, the lower pressing body 3000 is pressed against the part 8000, the lower guide post 3100 and the first hole flanging die 3110 return to the position and complete the withdrawal of the part 8000, and finally the demolding of the part 8000 is completed.
In order to enable the upper guide post 2100 to slidably penetrate through the upper pressing body 2000, an upper through hole is formed in the upper pressing body 2000, wherein an upper guide sleeve may be disposed in the upper through hole. The upper guide post 2100 is positioned within and in clearance fit with the upper guide sleeve.
In order to enable the lower guide post 3100 to slidably penetrate through the lower pressing body 3000, a lower through hole is formed in the lower pressing body 3000, and a lower guide sleeve may be disposed in the lower through hole. The lower guide post 3100 is positioned in the lower guide sleeve and is in clearance fit with the lower guide sleeve.
In order to prevent the upper guide sleeve and the lower guide sleeve from rotating and affecting hole flanging, rotation stopping blocks are arranged on the upper pressing body 2000 and the lower pressing body 3000 respectively, corresponding notches are arranged on the outer sides of the upper guide sleeve and the lower guide sleeve, and the rotation stopping blocks are propped against the notches so as to prevent the upper guide sleeve and the lower guide sleeve from rotating.
The hole flanging die is generally larger in size, so that the first hole flanging die 3110 can move directionally, a die guide sleeve can be arranged on the lower pressing body 3000, and the first hole flanging die 3110 is installed in the die guide sleeve.
In order to realize the pressing of the upper pad 1000 against the upper guide post 2100, in this embodiment, an upper pressing member 1200 is disposed on a side of the upper pad 1000 near the upper guide post 2100, and the upper pressing member 1200 is movably connected to the upper guide post 2100 and is used for pressing the upper guide post 2100.
During the pressing process, the relative position between the upper pressing member 1200 and the upper guide post 2100 is changed, and if the two are in direct contact, the contact surface of the two is lost due to long-time friction, so that the stroke of the upper guide post 2100 is insufficient, and the hole flanging effect is affected. It is generally possible to choose to replace the upper guide post 2100 or the pressing member with a new one, but the replacement process is troublesome and increases the cost.
As shown in fig. 3, in order to solve the above-mentioned problem, in the present embodiment, an upper abrasion block 1210 is fixedly provided at a side of the upper pressing member 1200 adjacent to the upper guide post 2100, and an upper friction block 2120 is fixedly provided at an end of the upper guide post 2100 opposite to the first hole-flanging punch 2110, wherein the upper abrasion block 1210 is in sliding contact with the upper friction block 2120. During hole flanging, the upper wear-resistant block 1210 presses the upper friction block 2120 to finish hole flanging, and the upper wear-resistant block and the upper friction block are contacted with each other and are connected in a sliding manner.
The upper wear block 1210 and the upper friction block 2120 may be made of copper alloy, graphite, metal, or other materials, or may be made of a case-carburized alloy. When wear occurs, only the new upper wear block 1210 or upper friction block 2120 need be replaced. Wherein, for convenience of replacement, the upper wear block 1210 and the upper friction block 2120 may be fastened to the upper pressing member 1200 and the upper guide post 2100 by bolting.
Accordingly, in order to realize the pressing of the lower pad 4000 against the lower guide column 3100, in this embodiment, a lower pressing member 4200 is disposed on a side of the lower pad 4000 near the lower guide column 3100, and the lower pressing member 4200 is movably connected to the lower guide column 3100 and is used for pressing the lower guide column 3100.
