BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0014] Figure 1 It is a structural schematic diagram of a movable combined quick-change work surface provided by the present invention;

[0015] Figure 2 The present invention is a schematic cross-sectional structure diagram of a movable combined quick-change work surface. DETAILED DESCRIPTION

[0016] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0017] like Figure 1 and Figure 2 As shown, the present invention provides a movable combined quick-change work surface, including a liftable push plate, a stamping operation support frame and a movable unloading frame which are arranged in sequence.

[0018] The liftable lifting push plate includes a pull rod 9, a push plate side bracket 10, a first push plate leg 11, a second push plate leg 14 and a first parallel roller group 8. The pull rod 9 and the first parallel roller group 8 are fixed to the push plate side bracket 10, and the push plate side bracket 10 is fixed to the base 16 through the first push plate leg 11 and the second push plate leg 14;

[0019] The liftable lifting push plate is composed of a set of parallel rollers 8, a connecting rod mechanism and a gas spring 13, which can achieve the effect of a single person feeding the material to the height of the stamping work surface. The gas spring 13 is a protective device. On the one hand, it can achieve slow descent, and on the other hand, it can ensure that the push plate will not slide and injure people after it is pulled into place; the lifting push plate can be set on one side or both sides of the workbench as needed. When lifting push plates are set on both sides, labor efficiency can also be improved. The middle part of the table is a stamping operation support frame. A parallel roller is still set on the side of the frame close to the lifting push plate as a fulcrum for the movement of the plate. The side of the frame close to the machine tool is suspended to avoid interference with the machine tool punch and other parts. At the other end of the table is a movable unloading rack. A crank slider mechanism is set on the bracket close to the operator. During the process of parallel movement of the plate to complete the punching, the operator can use the slider mechanism to move the unloading rack in a small range, thereby dragging the plate to move. When the entire plate is processed, the cutter head is lifted, and the plate reaches the supporting roller at the tail of the unloading rack. For a workbench with a lifting push plate only on one side, the slider mechanism of the mobile unloading device can be reset, and the plate can be dragged back to the early processing position, and then the lifting push plate on one side can be dragged back, and the lifting push plate can be pulled down to realize unloading; for a workbench with lifting push plates on both sides, the unloading operation can be carried out directly at the position where the processing is completed.

[0020] The stamping operation support frame is used to support the machine tool to be assembled, and includes a movable unloading frame 3, a rotating shaft 4, a crank 5, a fixing bolt group 6 and a second parallel roller 7. The movable unloading frame 3 is fixed between the first leg 15 and the second leg 17 through the rotating shaft 4, the fixing bolt group 6 and the guide rail 1, the crank 5 is connected to the movable unloading frame 3, and the second parallel roller 7 is fixed on the movable unloading frame 3.

[0021] The movable unloading frame includes a rotating shaft sleeve 20, a roller frame 21, a slide rail 19, and a handle 18; the rotating shaft 4 of the stamping operation support frame is fixed to the side of the roller frame 21 using the rotating shaft sleeve 20, and the slide rail 19 is fixed to the movable unloading frame 10 using a fixing bolt group 6.

[0022] Among them, a limit stopper 12 is set on the side of the first push plate leg 11 to limit the excessive tilt caused by manpower after lifting; a gas spring 13 is set on the side of the second push plate leg 14. The initial position of the gas spring 13 is tilted to achieve a slow descent effect, and when the lifting push plate is pulled into place, it is used to act as a push plate locking protection device. During operation, the effect of a single person lifting the plate to the height of the stamping work surface can be achieved. The limit stopper 12 can prevent the lifting push plate from pushing over and holding the gas spring 13. The gas spring 13 is a protection device. On the one hand, it can achieve a slow descent, and on the other hand, it can ensure that the push plate will not slide and injure people when the lifting push plate is pulled into place.

[0023] Among them, the stamping operation support frame is a single-sided structure, and a group of parallel rollers are arranged on the side of the frame close to the lifting push plate to serve as a fulcrum for the movement of the plate.

[0024] Among them, the movable unloading rack is provided with a crank slider mechanism on the side close to the operator, which can move the unloading rack in a small range, and parallel rollers are provided at the tail of the unloading rack to support the plates during the processing.

[0025] During the process of parallel movement of the plate to complete the punching, the operator can turn the handle 18 to drive the crank 5 to move along the slide rail 19, thereby realizing a small-range mobile unloading rack, and then dragging the plate to move. When the entire plate is processed, the cutter head is lifted, and the plate reaches the parallel roller group 2 at the tail of the unloading rack, for the workbench with a lifting push plate only on one side, the slider mechanism of the mobile unloading device can be reset, and the plate can be dragged back to the previous processing position, and then the lifting push plate on one side can be dragged back, and the lifting push plate can be pulled down to realize unloading; for the workbench with lifting push plates on both sides, the unloading operation can be directly performed at the position where the processing is completed.

[0026] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
