Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bending machine accessories, in particular to a special heavy-duty rear pneumatic support for bending machines. Background Art
[0002] Generally, a press brake has two rear stop fingers, and each rear stop finger is equipped with a heavy-duty rear pneumatic support. When the plate bent by the press brake extends into the interior of the press brake to a wider size, when the press brake is not equipped with a rear pneumatic support, the steel plate inserted into the interior of the press brake is in a suspended state, and it is easy to cause the workpiece to fall and deform due to the influence of gravity. The press brake equipped with a rear pneumatic support can now carry the plate on the supporting table of the rear pneumatic support to prevent the workpiece from falling and deforming due to gravity. However, the rear pneumatic support of the traditional press brake has the following disadvantages: 1. The supporting table is relatively thin and easy to deform and bend, and cannot support workpieces that are too heavy; 2. The cylinder diameter is small, and the cylinder thrust is insufficient. When supporting wide plates, the table resistance is large, and the cylinder extension and retraction are prone to jamming. Utility Model Content

[0021] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.
[0022] In the description of this utility model, it should be noted that, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integral connection; mechanical connection, electrical connection; direct connection, or indirect connection through an intermediary. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0023] Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5As shown, the rear pneumatic support base 3 is generally installed on the rear finger base of the bending machine by bolts. The cylinder fixing seat 4 is installed on the front end surface of the rear pneumatic support base 3 by screws, and the cylinder 2 is installed on it. Two sliders 6 are installed on the side of the rear pneumatic support base 3. The linear guide 5 cooperates with the slider 6, and the linear guide 5 can move freely in a straight line within the slider 6. The nylon anti-collision plate 9 is installed on the front end surface of the support table 1 by screws. The support table 1 is installed on the linear guide 5 by screws. The table cover 8 is installed on the upper surface of the support table 1 by screws. It has 8 shrinkage holes, and a universal steel ball 7 is installed in each shrinkage hole. A throttle valve 11 is installed on each of the two air holes of the cylinder 2. The T-block is locked on the protruding end of the cylinder 2. At the same time, the T-head of the T-block is stuck in the T-slot of the connecting block 10. The connecting block 10 is locked to the front end of the support table 1 by screws.
[0024] effect:
[0025] The rear pneumatic support base 3 serves as the structural main body of the entire heavy-duty rear pneumatic support, is fixed to the rear finger base of the bending machine, and can move along with the rear finger.
[0026] A slider 6 is installed on the rear pneumatic support base 3. The slider 6 cooperates with the linear guide 5, so that the support table 1 installed on the linear guide 5 can move linearly along the linear guide 5. The power for its movement is provided by the cylinder 2. The extended end of the cylinder 2 is connected to the T-block, and the T-block is clamped with the connecting block 10. When the piston rod of the cylinder 2 is extended, it can drive the support table 1 to extend together. It is convenient to support wider plates. A nylon anti-collision plate 9 is installed at the front end of the support table 1 to prevent the cylinder 2 from hitting the bending machine or the workpiece when it is extended, thereby damaging the support table 1.
[0027] Both air vents of the cylinder 2 are equipped with throttle valves 11. By rotating the knob on the throttle valve 11, the amount of air entering the cylinder 2 can be controlled to adjust the extension and contraction speed of the cylinder 2.
[0028] Universal ball transfers 7 are installed on the supporting table 1. When the table cover 8 supports the steel plate, the universal ball transfers 7 can rotate freely in all directions, and there is no sliding friction on the surface of the steel plate, and no scratches or damage to the surface of the steel plate. At the same time, since the universal ball transfers 7 can roll freely, the resistance between the supporting table 1 and the steel plate is reduced, which reduces the load on the cylinder when supporting heavy bending workpieces.
[0029] The supporting table 1 is made of 3mm steel plate bent and welded with reinforcement ribs, which has a strong bearing capacity and can bear heavy bending workpieces.
[0030] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
