Description

Technical Field

[0001] This utility model relates to the field of mobile workbench technology, and in particular to a device for removing the workbench of an overhead press. Background Technology

[0002] Most existing top-mounted hydraulic presses do not have a movable worktable, making mold changing complex and difficult. This is especially true for hydraulic presses with heating functions, where molds can only be changed after the worktable has cooled down, resulting in wasted time. If external work frames such as lifting arms are used, they can generally only be used in bottom-press presses with relatively fixed lower crossbeams. If they are forced to be used in top-mounted presses, external work frames such as lifting arms must be installed on the slide block. Installing external work frames on moving parts is very dangerous and can easily lead to accidents.

[0003] Therefore, this utility model proposes a device for removing the worktable of an top-mounted press, which allows the movable worktable to be removed when the slider returns to the bottom set position, thus ensuring the safety performance of the equipment and solving the defect that the top-mounted press cannot remove the worktable. Summary of the Invention

[0004] The purpose of this utility model is to solve the problems existing in the prior art and to propose a device for removing the worktable of an upper-mounted press.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for removing a worktable from an overhead press includes: a hydraulic press body, a column mounted on the hydraulic press body, a movable beam sliding on the column, a main cylinder connected to the lower plate of the movable beam, and a control system for controlling the movement of the main cylinder. The main cylinder passes through the lower beam and is fixed to the lower beam. A heat insulation plate and a heating plate are sequentially fixedly mounted on the upper plate of the movable beam. Multiple adjustable-height ejection mechanisms are symmetrically arranged on both sides of the lower beam. The multiple ejection mechanisms pass through the movable beam, the heat insulation plate, and the heating plate. A worktable is mounted on the upper plate of the heating plate. The worktable and the ejection mechanism are slidably connected. A ejection mechanism for ejecting the worktable is fixedly connected to the front end of the worktable.

[0007] Furthermore, the ejection mechanism includes an adjusting bolt, a screw, and a ejector rod, a guide block, and a first roller assembly. The ejector rod is fixed inside the lower beam. The adjusting bolt is threaded to the lower end of the screw, and the upper end of the screw is threaded to the lower end of the ejector rod. The upper end of the ejector rod is slidably connected to the guide block, the guide block is fixedly connected to the lower beam, and the top of the ejector rod is fixedly connected to the first roller assembly.

[0008] Furthermore, the upper plane of the guide block is flush with the upper plane of the lower beam.

The top of the top rod is fixedly connected to the roller mounting base, the roller mounting base is fixedly connected to the first connecting shaft, and the first roller is rotatably connected to the first connecting shaft.

[0010] Furthermore, the first roller assembly passes through the heat insulation plate and the heating plate, and the first roller contacts the worktable.

[0011] Furthermore, the ejection mechanism includes an ejection cylinder, a second bearing, a second connecting shaft, and a connecting frame. The ejection cylinder passes through and is fixedly connected to the lower beam. The telescopic end of the ejection cylinder is connected to the second bearing. The second bearing is fitted with the second connecting shaft. The second connecting shaft is connected to the connecting frame. The upper end of the connecting frame is connected to the front end of the worktable. The ejection cylinder is controlled by the control system.

[0012] Furthermore, the ejection mechanism is also connected to two sets of external support platforms, which are placed symmetrically. Each external support platform includes a support frame and a second roller assembly. The support frame is fixed to the ground, and multiple second roller assemblies are arranged on the support frame along the direction of the worktable's movement.

[0013] Furthermore, the outer support platform abuts against one side of the hydraulic press body.

[0014] Furthermore, the roller assembly is on the same horizontal plane as the first roller assembly.

[0015] Furthermore, guide baffles for guiding the worktable are fixed on both sides of the hydraulic press body.

[0016] Compared with existing technologies, the present invention provides a device for removing the worktable of an overhead press, which has the following advantages:

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left side", "right side", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. At the same time, the terms "first", "second", etc., are only used to distinguish the names of each component and do not have a primary or secondary relationship. Therefore, they should not be construed as limitations on this utility model.

[0028] Example 1, such as Figure 1 and Figure 2 As shown, a device for removing the worktable of an overhead press includes: a hydraulic press body 1, a column 2 mounted on the hydraulic press body 1, a movable beam 3 sliding on the column 2, a main cylinder 4 connected to the lower plate of the movable beam 3, and a control system for controlling the movement of the main cylinder 4. The main cylinder 4 passes through the lower beam 5 and is fixed to the lower beam 5. A heat insulation plate 6 and a heating plate 7 are sequentially fixedly mounted on the upper plate of the movable beam 3. Multiple adjustable-height ejection mechanisms 8 are symmetrically arranged on both sides of the lower beam 5. The multiple ejection mechanisms 8 pass through the movable beam 3, the heat insulation plate 6, and the heating plate 7. A worktable 10 is mounted on the upper plate of the heating plate 7. The worktable 10 and the ejection mechanisms 8 are slidably connected. An ejection mechanism 9 for ejecting the worktable 10 is fixedly connected to the front end of the worktable 10.

[0029] With this technical solution, after the hydraulic press finishes pressing, the movable beam 3 moves downward, causing the worktable 10 to fall onto the ejection mechanism 8, and then be ejected by the ejection mechanism 9.

[0030] Example 2, as Figure 3 As shown, the ejector mechanism 8 includes an adjusting bolt 80, a screw 81, and a ejector rod 82, a guide block 83, and a first roller assembly 84. The ejector rod 82 is fixed inside the lower beam 5. The adjusting bolt 80 is threaded to the lower end of the screw 81, and the upper end of the screw 81 is threaded to the lower end of the ejector rod 82. The upper end of the ejector rod 82 is slidably connected to the guide block 83. The guide block 83 is fixedly connected to the lower beam 5, and the upper surface of the guide block 83 is flush with the upper surface of the lower beam 5. The top of the ejector rod 82 is fixedly connected to the first roller assembly 84.

[0031] In this embodiment, there are 8 sets of ejection mechanisms 8. The adjusting bolts 80 at the bottom of the ejection mechanism 8 can adjust the height of the ejector rod 82, so that multiple ejection mechanisms 8 can be at the same height, so that the worktable 10 can be moved out horizontally.

[0032] Please continue to refer to Figure 3 To facilitate smoother movement of the worktable 10, the first roller assembly 84 includes a first roller, a first connecting shaft, and a roller mounting base. The roller mounting base is fixedly connected to the top of the push rod 82, and the roller mounting base is fixedly connected to the first connecting shaft. The first roller is rotatably connected to the first connecting shaft, and retaining springs are fitted at both ends of the first connecting shaft to secure the first roller. The first roller assembly 84 passes through the heat insulation plate 6 and the heating plate 7, and the first roller contacts the worktable 10. When the worktable 10 moves on it, this assembly not only reduces friction during movement but also provides stable guidance.

[0033] Example 3, as Figure 4 As shown, the ejection mechanism 9 includes an ejection cylinder 90, a second bearing 91, a second connecting shaft 92, and a connecting frame 93. The ejection cylinder 90 passes through and is fixedly connected to the lower beam 5. The telescopic end of the ejection cylinder 90 is connected to the second bearing 92. The second bearing 91 is internally connected to the second connecting shaft 92. The second connecting shaft 92 is connected to the connecting frame 93. The upper end of the connecting frame 93 is connected to the front end of the worktable 10. The ejection cylinder 90 is controlled by the control system.

[0034] When the worktable 10 is to be pushed out, the control system controls the push-out cylinder 90, which pushes the connecting frame 93 and drives the worktable 10 out of the hydraulic press.

[0035] Example 4, please refer to Figure 1To provide a resting place for the worktable 10 during ejection, the ejection mechanism 9 is also externally connected to two sets of external support platforms 11. These two sets of external support platforms 11 are symmetrically placed. Each external support platform 11 includes a support frame and a second roller assembly. The support frame is fixed to the ground, and multiple second roller assemblies are arranged along the direction in which the worktable 10 moves out. The external support platform 11 abuts against one side of the hydraulic press body 1. The second roller assembly and the first roller assembly 84 are on the same horizontal plane. When the worktable 10 is ejected by the ejection cylinder 90, it moves onto the external support platform 11 via the second roller assembly. The distance the worktable 10 moves out is the output distance of the piston rod of the ejection cylinder 90. Limit sensors can also be installed on the external support platform 11 to limit the position of the worktable 10 during ejection.

[0036] In Example 5, to prevent the worktables 10 from exceeding their safe operating range and to ensure they move along a predetermined path or trajectory, reducing deviation and error, guide baffles are fixed on both sides of the hydraulic press body 1 to guide the worktables 10. These guide baffles also limit the movement of the worktables 10. To ensure the position of the worktables 10 is determined, a limiting plate is provided on the side of the movable beam 3 away from the outer support platform 11 to limit the position of the worktables 10. Thus, the position of the worktables 10 on the movable beam 3 is defined.

[0037] Similarly, the support frames of the two sets of outer support platforms 11 are respectively provided with outer guide baffles on their sides, and the outer guide baffles on the same side are on the extension line of the guide baffles.

[0038] Working principle: This hydraulic press is installed in a pit, and the outer support platform 11 is installed on the ground. After the pressing is completed, because it is an upward-mounted hydraulic press, the movable beam slides down, and the worktable 10 also slides down and stops at the position set by the control system. The worktable 10 rests on multiple first rollers. If it is necessary to change the mold, the control system controls the extension cylinder 90 to extend, which drives the worktable 10 to move out of the hydraulic press. The worktable 10 moves out along the first roller assembly 84 and the second roller assembly, so that the mold can be changed outside the hydraulic press.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
