Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic bending machines, in particular to a positioning structure for a hydraulic bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates. Its structure mainly includes a bracket, a workbench and a clamping plate. The workbench is placed on the bracket. The workbench is composed of a base and a pressure plate. The base is connected to the clamping plate by a hinge. The base is composed of a base shell, a coil and a cover plate. The coil is placed in the recess of the base shell, and the top of the recess is covered with a cover plate. When in use, the coil is energized by a wire, and after power is turned on, an attractive force is generated on the pressure plate, thereby clamping the thin plate between the pressure plate and the base.

[0003] The existing positioning structure of the hydraulic bending machine for hardware metal sheets is generally aimed at the traditional bending machine, which is composed of four steel pipes cut at the end, and welded into one after cutting the inclined surface. This method is laborious and requires multiple processing. The problem of low processing efficiency is being improved. For example, a hydraulic bending machine disclosed in the authorized Chinese patent CN212884378U can be used in conjunction with a chassis, a mounting frame, a lifting cylinder, a lifting seat, a slide rail, a slider, a punching seat, a slide groove, a punching cylinder, a punching knife, a steel pipe seat, a steel pipe groove, a punching groove, a fixing seat, a fixing bolt and a corresponding groove to achieve punching out a right-angled triangle groove on a steel pipe, forming two inclined surfaces that cooperate with each other, and folding and pressing here to form a rectangular bending right angle, which is convenient for processing.

[0004] However, the hydraulic press brakes in the above cited documents generally perform bending processing on plates by manually loading the plates, placing the plates on the press brakes for bending, and have no positioning function for the plates. The plates are prone to shifting during processing, which affects the processing efficiency, and the use effect of the existing hydraulic press brakes needs to be improved. Utility Model Content

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-3 The utility model provides a technical solution: a positioning structure of a hydraulic bending machine for hardware metal plates, comprising a workbench 1 and a protective cover 2, one side of the protective cover 2 is fixedly mounted on the workbench 1; two sets of positioning structures 300 in mirror symmetry are fixedly mounted on the side of the workbench 1 away from the ground, and the positioning structures 300 are located in the protective cover 2;

[0028] By cooperating with each other between the protective cover 2 and the positioning structure 300 on the workbench 1, the plate can be positioned and clamped when loading the plate, and the two ends of the plate can be limited and fixed so that the plate will not deviate, so that the plate can be accurately bent during processing. At the same time, the plate can be fixed and the positioning and fixation of the plate can be strengthened, thereby effectively improving the use effect of the existing hydraulic bending machine.

[0029] In the first embodiment, the positioning structure 300 is a structure for positioning and clamping a plate.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the positioning structure 300 includes a U-shaped bracket 301 fixedly installed on the side of the workbench 1 away from the ground and a fixed cylinder 302 fixedly installed on the side of the U-shaped bracket 301 away from the workbench 1, and the fixed cylinder 302 passes through the workbench 1, and a driving box 303 is fixedly installed on the end of the fixed cylinder 302 away from the workbench 1, a driving assembly is installed on one side of the driving box 303, a transmission assembly connected to the driving assembly is installed on the inner side of the driving box 303, a threaded pushing assembly and two adjustment blocks 307 respectively connected to both sides of the threaded pushing assembly are connected to the transmission assembly, a clamping assembly is connected to the side of the threaded pushing assembly away from the driving assembly and the inner wall of the U-shaped bracket 301, and the two groups of clamping assemblies are distributed in a mirror-symmetrical manner.

[0031] It should be noted that the drive assembly includes a fixed mounting plate 3041 and a servo motor 3042; one side of the fixed mounting plate 3041 is fixedly mounted on one side of the drive box 303 by bolts, and one side of the servo motor 3042 is fixedly mounted on one side of the fixed mounting plate 3041. Both servo motors 3042 and the synchronous controller are prior art and belong to common knowledge. The electrical signal connection is not described in detail in this article. The synchronous controller controls the speed and position of the two servo motors 3042 so that they can work together to achieve the purpose of synchronous movement.

[0032] It can be understood that the output shaft of the servo motor 3042 is connected to the transmission assembly, and the servo motor 3042 drives the transmission assembly to rotate in order to stably drive the transmission assembly to rotate.

[0033] In addition, the transmission assembly includes a worm 3051 and a worm wheel 3052; one end of the worm 3051 is rotatably connected to the inner wall of the drive box 303 through a bearing, and the other end passes through the drive box 303 and is fixedly connected to the output shaft of the servo motor 3042.

[0034] In this embodiment, the servo motor 3042 is connected to the worm wheel 3052 via the worm 3051. The servo motor 3042 drives the worm 3051 to rotate, thereby driving the worm wheel 3052 meshed with the worm 3051 to rotate, so as to drive the threaded pushing assembly to move stably.

[0035] It should also be noted that the threaded pushing assembly includes a threaded rod 3061 and a threaded sleeve 3062; one end of the threaded rod 3061 passes through the fixed cylinder 302 and the drive box 303 in sequence and extends into the worm gear 3052, the outer side of the threaded rod 3061 is fixedly connected to the inner side of the worm gear 3052, and the inner side of the threaded sleeve 3062 is threadedly connected to the outer side of the threaded rod 3061.

[0036] It should be further explained that the threaded rod 3061 rotates under the drive of the worm gear 3052, and the threaded sleeve 3062 moves on the outside of the threaded rod 3061 under the rotation thrust of the inner thread, so as to drive the clamping assembly to move.

[0037] It should also be noted that the two adjustment blocks 307 are respectively fixedly connected to the outside of the threaded sleeve 3062 and are distributed in a mirror-symmetrical manner. An adjustment groove 308 is provided on the inner wall of the fixed cylinder 302 for the adjustment block 307 to slide in. This is to improve the movement stability of the threaded sleeve 3062 while limiting the moving distance of the threaded sleeve 3062.

[0038] In addition, the clamping assembly includes a pressure plate 3091 and an anti-slip protrusion 3092; there are two pressure plates 3091, one of which is fixedly installed on the side of the threaded sleeve 3062 close to the workbench 1 by bolts, and the other pressure plate 3091 is fixedly installed on the inner wall of the U-shaped bracket 301 by bolts, and the two pressure plates 3091 are distributed in a mirror-symmetrical manner, one side of the anti-slip protrusion 3092 is fixedly connected to one side of the pressure plate 3091, and the number of anti-slip protrusions 3092 is multiple and evenly distributed, in order to limit and fix the two ends of the plate so that the plate will not be offset, so that the plate can be accurately bent during processing.

[0039] It should also be noted that one of the pressure plates 3091 moves under the moving thrust of the threaded sleeve 3062 in order to facilitate the adjustment of the tightness when clamping the plate.

[0040] The working principle of the above embodiment is:

[0041] When it is necessary to clamp the plate, first place the two ends of the plate between the opposite sides of the two pressure plates 3091, then start the servo motor 3042, and under the control of the synchronous controller, make the two servo motors 3042 move synchronously, at this time, the worm 3051 is driven to rotate under the rotation support of the bearing, so as to drive the worm wheel 3052 engaged on the worm 3051 to rotate, and drive the threaded rod 3061 to rotate, because the threaded sleeve 3062 can only move in the fixed cylinder 302 under the sliding connection between the adjusting block 307 and the adjusting groove 308, so the threaded sleeve 3062 is stably lifted and lowered on the outside of the threaded rod 3061 under the thrust of the inner thread rotation, and pushes one of the pressure plates 3091 to move, when the anti-slip protrusions 3092 on the two pressure plates 3091 contact and abut the plate, the plate can be positioned and clamped, and the two ends of the plate are limited and fixed to prevent the plate from shifting.

[0042] Compared with the prior art: the positioning structure of the hydraulic bending machine for hardware metal sheets, through the mutual cooperation between the protective cover 2 and the positioning structure 300 on the workbench 1, can position and clamp the sheet when loading the sheet, and limit and fix the two ends of the sheet so that the sheet will not deviate, so that the sheet can be accurately bent during processing. At the same time, the sheet can be fixed and the positioning and fixation of the sheet can be strengthened, thereby effectively improving the use effect of the existing hydraulic bending machine and solving the problem of poor use effect of the existing hydraulic bending machine.

[0043] The electrical components appearing in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing publicly available power connection technology and power supply are also common knowledge in the field, so this application will not go into details.

[0044] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.
