DETAILED DESCRIPTION

[0021] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0022] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "connected" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The ball 1 shown is mounted on the front support workbench 2 via a shaft retaining spring, the open linear guide 3 is fixed to the lower surface of the front support workbench 2 via screws, and the slider of the open linear guide 3 is fixed to the connecting plate 4 on the frame via screws. The upper connecting plate 4 of the frame is connected to the two frame side connecting plates 6 by screws, and the two sides of the frame connecting square tube 5 are connected to the frame side connecting plates 6 by screws. The two frame side connecting plates 6 are connected and fixed to the frame fixing block 7 by screws. Two linear bearings 13 and a lifting nut 14 are installed inside the frame fixing block 7, and they are fixed to each other by screws. The two linear bearings 13 are directly sleeved on the optical axis guide rail 11 and can slide up and down the optical axis guide rail 11. The lifting nut 14 and the lifting screw 12 are screwed together. The upper ends of the two optical axis guide rails 11 are stuck in the circular holes on both sides of the upper end fixing plate 10 of the screw rod, and are fixed to the upper end fixing plate 10 of the screw rod by tightening screws. The lower ends of the two optical axis guide rails 11 are stuck in the circular holes on both sides of the lower end fixing plate 9 of the screw rod, and are fixed to the lower end fixing plate 9 of the screw rod by tightening screws. The upper end bearing 15 of the screw rod is sleeved on the upper end shaft of the lifting screw rod 12, and the upper end bearing 15 of the screw rod is installed at the same time. It is installed inside the upper fixing plate 10 of the screw rod and fixed by a retaining ring through the hole. The lower end bearing 16 of the screw rod is sleeved on the lower end shaft of the lifting screw rod 12. At the same time, the lower end bearing 16 of the screw rod is installed inside the lower end fixing plate 9 of the screw rod and fixed by a retaining ring through the hole. The upper end fixing plate 10 of the screw rod is installed on the heavy-loaded front supporting body mounting plate 8 by screws, and the lower end fixing plate 9 of the screw rod is installed on the heavy-loaded front supporting body mounting plate 8 by screws. The heavy-duty front supporting sliding guide slider 21 is fixed on the heavy-duty front supporting body mounting plate 8 by screws, and the supporting bearing adjusting rotating pin shaft 23 is fixed on the heavy-duty front supporting body mounting plate 8 by screws. The supporting bearing mounting block 24 is sleeved on the supporting bearing adjusting rotating pin shaft 23 through the hole above it, and the supporting bearing 25 is fixed on the supporting bearing mounting block 24 by a nut. The right-angle gear steering gear 17 is sleeved on the lower end shaft of the lifting screw rod 12, and the handwheel 18 is sleeved on one end input shaft of the right-angle gear steering gear 17.

[0024] Function: The ball bearings 1 are installed on the front support workbench 2. By arranging rows of ball bearings on the workbench, the friction of the bent steel plate on the workbench is effectively reduced, which reduces the workload of the bending operator. At the same time, the ball bearings can also reduce the scratches on the surface of the bent plate during the bending work and protect the plate.

[0025] The front supporting workbench 2 is connected to the connecting plate 4 on the frame through an open linear guide rail 3, so that the front supporting workbench 2 can be adjusted and moved forward and backward to be suitable for bending plates of different widths.

[0026] The frame upper connecting plate 4, the frame connecting square tube 5, the two frame side connecting plates 6 and the frame fixing block 7 are fastened and fixed by screws to form the main frame of the heavy-load front support, thereby ensuring the stability of the heavy-load front support when in use.

[0027] Part 7. There are two linear bearings 13 and a lifting nut 14 inside the frame fixing block. Together with the two optical axis guide rails 11 and a lifting screw 12, a set of lifting and adjusting mechanism is formed. By manually turning the hand wheel 18 and transmitting the rotation of the hand wheel 18 to the lifting screw 12 through the right-angle gear steering gear 17, the lifting screw 12 rotates to drive the lifting nut 14 to move up and down, thereby realizing the height adjustment of the front support workbench 2 to adapt to different types of bending machines.

[0028] All parts of the heavy-duty front support are finally installed on the heavy-duty front support main body mounting plate 8. The heavy-duty front support sliding guide slider 21 installed above the heavy-duty front support main body mounting plate 8 cooperates with the guide rail installed on the lower beam of the bending machine to realize the free left and right movement of the heavy-duty front support on the bending machine. Generally, the front supports are used in pairs, and the distance between the two heavy-duty front supports is adjusted to be used for bending plates of different widths.

[0029] A support bearing adjustment rotating pin 23, a support bearing mounting block 24, and a support bearing 25 are provided below the heavy-loaded front support body mounting plate 8. The support bearing mounting block 24 can be rotated and adjusted with the support bearing adjustment rotating pin 23 as the center of the circle, and the support bearing mounting block 24 is supported from the back of the heavy-loaded front support body mounting plate 8 by screws, so that the support bearing 25 is always supported on the surface of the lower beam of the bending machine, and the weight borne by the heavy-loaded front support is transmitted to the lower beam through the support bearing 25, thereby ensuring the service life of the heavy-duty front support sliding guide slider 21.

[0030] The front support workbench fixing clamp 19 is installed on the connecting plate 14 on the frame. By turning the wrench of the front support workbench fixing clamp 19, the top of the front support workbench fixing clamp 19 presses the lower surface of the front support workbench 2, so that the workbench can be fixed within its adjustment range.

[0031] The function of the heavy-duty front support fixing clamp 20 is similar to that of the front support workbench fixing clamp 19. After the spacing between the two heavy-duty front supports used in pairs is adjusted, the wrench of the heavy-duty front support fixing clamp 20 is turned so that the top of the heavy-duty front support fixing clamp 20 presses the surface of the guide rail installed on the lower beam of the bending machine, so that the heavy-duty front support is fixed as a whole.

[0032] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without deviating from the technical concept of the utility model through the above description. The technical scope of the utility model is not limited to the content of the specification, and its technical scope must be determined according to the scope of the claims.
