Description

Technical Field

[0001] This utility model belongs to the field of pressure arm technology, specifically relating to an adjustable pressure arm for an automated punch press. Background Technology

[0002] A punch press is a stamping press. In national production, stamping technology has a wide range of applications because it saves materials and energy and is more efficient than traditional machining. When a punch press stamps steel plates, a pressure arm is needed to compact the steel plate to prevent it from warping after being impacted by the stamping structure.

[0003] For example, Chinese utility model patent application number 202221033253.5 discloses an adjustable pressure arm for an automated punch press. In this utility model, the operator starts a motor, which rotates a threaded rod and drives the pressure plate to move along a slide groove by screwing the thread. The operator starts a dual-axis motor, and the output shaft of the dual-axis motor drives the first gear to rotate around the support rod. Through the cooperation of the first gear, the first rack, the dovetail groove, and the moving block, the pressure plate moves along the dovetail groove. This allows the operator to move the position of the pressure plate according to the size of the steel plate, so that the pressure plate can compact steel plates of different sizes, thus improving the practicality of this pressure arm.

[0004] However, the aforementioned solution still has shortcomings. The solution uses a pressure plate to press down the steel plate to prevent it from warping and has a structure that allows the pressure plate to be transferred, thus realizing the functions of pressing and unloading. However, in actual use, the steel plate sometimes needs to be pushed forward by the operator during the stamping process. The aforementioned solution uses a pressure plate that fits against the steel plate for limiting, which cannot take into account the processing flow of the steel plate moving forward. It requires the pressing device to lift the pressure plate before proceeding, which is quite troublesome. Furthermore, the pressure plate driven by the cylinder presses directly onto the steel plate, which can easily damage the steel plate if it is thin, making it a significant drawback.

[0005] To address the aforementioned issues, this application proposes an adjustable pressure arm for an automated punch press. Utility Model Content

[0006] To address the aforementioned problems in the existing technology, this utility model provides an adjustable pressure arm for an automated punch press, which features adaptive pressure and ease of maintenance.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an adjustable pressure arm for an automated punch press, comprising a support base plate, wherein universal self-locking wheels are provided at the four bottom corners of the support base plate, and symmetrically distributed support slide rods are provided at the top of the support base plate, with a support top plate connected to the top of two of the support slide rods. It also includes a lifting mechanism, a pressing mechanism, and a buffer mechanism; The lifting mechanism includes a one-way threaded rod rotatably connected between the support base plate and the support top plate. A drive motor for driving the one-way threaded rod is provided on the top of the support top plate. A vertically movable lifting plate is threadedly connected to the one-way threaded rod. The lifting plate is slidably connected to two support slide rods. The pressing mechanism is mounted on the lifting plate and is used to press the limiting steel plate; The buffer mechanism is connected to the pressing mechanism and is used to reduce the pressure exerted by the pressing mechanism on the steel plate.

[0008] Preferably, the lifting plate has multiple lightweight cuts.

[0009] Preferably, the pressing mechanism includes a cylinder disposed on the lifting plate, the telescopic rod of the cylinder passing through the lifting plate and connected to a movable frame at its end, and the top of the movable frame is provided with symmetrically distributed positioning columns, and the two positioning columns are slidably connected to the lifting plate.

[0010] Preferably, the bottom ends of the movable frame are provided with symmetrically distributed L-shaped plates, and pressure components are provided on the L-shaped plates.

[0011] Preferably, the pressing component includes a straight plate and a pressing roller. The bottom of the straight plate is provided with symmetrically distributed vertical plates. The pressing roller is rotatably installed between the two vertical plates. The pressing roller can be moved vertically by the lifting plate or by the cylinder.

[0012] Preferably, the movable frame has symmetrically distributed second sliding joint holes, and the movable frame and the straight plate are also provided with buffer components. The buffer components include sliding rods inserted into the second sliding joint holes, the sliding rods being connected to the L-shaped plate, and a first sliding joint hole being provided on the straight plate to slide with the sliding rods. The outer ring of the sliding rods is fitted with buffer springs, and the buffer springs are in contact with the straight plate and the movable frame respectively.

[0013] Preferably, the L-shaped plate is provided with a threaded hole, the bottom end of the sliding rod is provided with an external thread that matches the threaded hole, and the top end of the sliding rod is provided with a hand-tightening knob.

[0014] Compared with the prior art, the beneficial effects of this utility model are: In this invention, a rotatable pressure roller replaces the traditional pressure plate structure. During the stamping process, it effectively prevents the steel plate from warping while allowing it to move freely in the horizontal direction. This solves the problem of the traditional pressure plate structure hindering feeding. The buffer mechanism ensures that when the pressure roller contacts the steel plate, the buffer spring is first compressed to form a flexible buffer layer, allowing the pressure to increase gradually. This is suitable for thin plate processing and effectively avoids steel plate deformation caused by excessive pressure. In addition, the threaded connection design between the sliding rod and the L-shaped plate facilitates quick disassembly and replacement of the buffer spring and pressure roller, reducing maintenance costs and increasing the service life of the equipment.

[0015] Other additional advantages and benefits of this application will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of this application. Attached Figure Description

[0018] 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. Example

[0019] Please see Figures 1-4 The present invention provides the following technical solution: an adjustable pressure arm for an automated punch press, including a support base plate 1, with universal self-locking wheels 2 provided at the four corners of the bottom of the support base plate 1, and symmetrically distributed support slide rods 3 provided at the top of the support base plate 1, with a support top plate 4 connected to the top of the two support slide rods 3. It also includes a lifting mechanism, a pressing mechanism, and a buffer mechanism; The lifting mechanism includes a one-way threaded rod 5 rotatably connected between the support base plate 1 and the support top plate 4. A drive motor 6 is provided on the top of the support top plate 4 to drive the one-way threaded rod 5. A vertically movable lifting plate 7 is threadedly connected to the one-way threaded rod 5. The lifting plate 7 is slidably connected to two support slide rods 3. During use, when the drive motor 6 is activated in forward rotation mode, the lifting plate 7 can be moved upward through the one-way threaded rod 5. When the drive motor 6 is activated in reverse rotation mode, the lifting plate 7 can be moved downward through the one-way threaded rod 5, thereby allowing the device to be adjusted for use according to the height of the punch press equipment.

[0020] The pressing mechanism is mounted on the lifting plate 7 and is used to press the limiting steel plate; The buffer mechanism is connected to the pressing mechanism and is used to reduce the pressure exerted by the pressing mechanism on the steel plate.

[0021] Preferably, by Figure 1 As shown, in this embodiment, the lifting plate 7 has multiple lightweight cuts 8; this arrangement facilitates the reduction of materials and the overall weight of the device, making it easier to transport.

[0022] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the pressing mechanism includes a cylinder 9 mounted on the lifting plate 7. The telescopic rod of the cylinder 9 passes through the lifting plate 7 and is connected to a movable frame 11 at its end. The top of the movable frame 11 is provided with symmetrically distributed positioning columns 10. The two positioning columns 10 are slidably connected to the lifting plate 7. The positioning columns 10 can support and limit the lifting plate 7, prevent the lifting plate 7 from rotating due to the threaded connection force, and ensure that it can move smoothly in the vertical direction, thereby achieving the function of stable adjustment.

[0023] The bottom ends of the movable frame 11 are provided with symmetrically distributed L-shaped plates 12, and pressure members 13 are provided on the L-shaped plates 12.

[0024] The pressing component 13 includes a straight plate 15 and a pressing roller 18. The bottom of the straight plate 15 is provided with symmetrically distributed vertical plates 17. The pressing roller 18 is rotatably installed between the two vertical plates 17. The pressing roller 18 can be moved vertically by the lifting plate 7 or by the cylinder 9. In use, the pressing roller 18 is positioned directly above the steel plate to be pressed. Then, the cylinder 9 is activated to drive the moving frame 11 to move down, so that the pressing roller 18 is pressed onto the steel plate, thereby achieving the pressing and limiting of the steel plate.

[0025] Preferably, by Figure 1 , Figure 2 and Figure 4 As shown, in this embodiment, the movable frame 11 has symmetrically distributed second sliding joint holes 22. The movable frame 11 and the straight plate 15 are also equipped with buffer members 14. The buffer member 14 includes a sliding rod 20 inserted into the second sliding joint hole 22. The sliding rod 20 is connected to the L-shaped plate 12. The straight plate 15 has a first sliding joint hole 16 that slides with the sliding rod 20. A buffer spring 23 is sleeved around the outer edge of the sliding rod 20. The buffer spring 23 contacts the straight plate 15 and the movable frame 11 respectively. The cylinder 9 pushes the pressure roller 18 to press... When the pressure roller 18 contacts the steel plate, the reverse force causes the pressure roller 18 to move upward, thereby compressing the buffer spring 23. The buffer spring 23 absorbs part of the pressure, which not only limits the steel plate but also prevents excessive pressure from deforming the thin steel plate, thus providing protection. Furthermore, since the pressure roller 18 is rotating during the steel plate stamping process, the operator does not need to activate the cylinder 9 to disengage the pressure roller 18 from the steel plate when pushing the steel plate. This allows for both pressure limiting and movement of the steel plate, improving practicality.

[0026] The L-shaped plate 12 is provided with a threaded hole 19, and the bottom end of the sliding rod 20 is provided with an external thread 21 that matches the threaded hole 19. The top end of the sliding rod 20 is provided with a hand-tightening knob 24. After long-term use, if the buffer spring 23 is damaged or its elastic potential energy is reduced, the sliding rod 20 can be unscrewed counterclockwise for replacement. This setting also facilitates the replacement and maintenance of the pressure roller 18, making it convenient to use.

[0027] Components not described in detail in this article are existing technologies.

[0028] The working principle and usage process of this utility model are as follows: During use, the pressure roller 18 is positioned directly above the steel plate to be stamped. Then, the cylinder 9 is activated to move the moving frame 11 downward, causing the pressure roller 18 to press against the steel plate, thus limiting the pressure on the steel plate. When the cylinder 9 pushes the pressure roller 18 to press, after the pressure roller 18 contacts the steel plate, the reverse force will cause the pressure roller 18 to move upward, thereby compressing the buffer spring 23. The buffer spring 23 absorbs part of the pressure, thus limiting the pressure on the steel plate while preventing excessive pressure from deforming the thin steel plate, thereby playing a protective role. Furthermore, during the stamping process of the steel plate, since the pressure roller 18 is rotatable, when the operator pushes the steel plate, there is no need to activate the cylinder 9 to disengage the pressure roller 18 from the steel plate. This achieves both pressure limiting and the ability to move the steel plate, improving practicality.

[0029] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
