Abstract
Description
Technical Field
[0001] This invention relates to the field of sign processing technology, specifically to a bending machine for sign processing and its usage method. Background Technology
[0002] In the field of sign processing technology, bending machines are the core equipment for forming sign blanks (such as aluminum alloy sheets, stainless steel sheets, acrylic sheets and other commonly used sign substrates), and are widely used in the production and processing of various signs such as traffic signs, commercial nameplates, and industrial signs.
[0003] Currently, the mainstream bending machines for sign processing in the industry typically consist of a base, a fixing mechanism, a bending module, and a drive component. The working principle is as follows: the fixing mechanism positions and fixes the sign blank on the lower bending module, and then the drive component drives the upper bending module to press down in the vertical direction. The cooperation between the upper and lower bending modules causes the blank to undergo plastic deformation, and finally completes the bending and forming of the preset angle or arc.
[0004] However, existing bending machines for sign processing still have the following problems in practical applications: 1. The mold fixing operation is cumbersome and inefficient: Traditional bending machines mostly use bolts to directly lock or mechanical buckles to fix the lower module. The installation and disassembly process requires repeated operation with tools, which is not only time-consuming and labor-intensive, but also prone to thread wear or positioning deviation when frequently changing molds, affecting the service life of the equipment and processing accuracy.
[0005] 2. The mold is prone to displacement during the bending process, which affects the forming accuracy: During the bending process, due to uneven stress on the blank or the mold not being fixed firmly, the lower module is prone to slight horizontal displacement, which leads to the deviation of the bending line and inaccurate angle, seriously affecting the appearance quality and dimensional consistency of the sign. This problem is particularly prominent when high-precision signs are bent in multiple ways.
[0006] 3. Inconvenient mold replacement and adjustment, poor adaptability: When changing bending dies of different specifications or angles, existing equipment often requires re-centering and leveling, which is complicated and lacks a quick positioning and locking mechanism. This makes it difficult to adapt to the flexible production needs of small batches and multiple varieties, thus restricting the improvement of production efficiency and processing flexibility. Therefore, a bending machine for sign processing and its usage method are proposed to address the above situation. Summary of the Invention
[0007] The purpose of this invention is to provide a bending machine for sign processing and its usage method. By combining magnetic fixing, slot positioning and lateral horizontal locking, the invention solves the problems of cumbersome mold fixing operation, easy displacement during bending leading to poor accuracy, and low mold replacement efficiency in the prior art.
[0008] This invention is achieved through the following technical solution: This invention is a bending machine for sign processing, comprising a base assembly, a fixing assembly, and a mounting bracket.
[0009] The base assembly includes a base, and a slot is provided at the center of the top of the base.
[0010] The fixing component includes a magnetic fixing plate. The top of both sides of the magnetic fixing plate protrudes upward to form two protrusions. The protrusions are provided with mounting grooves. Nuts are embedded and fixed in the mounting grooves. Long bolts are threaded into the nuts. Anti-slip blocks are fixedly connected to the ends of the long bolts.
[0011] Two hydraulic push rods are fixedly installed on the bottom surface of the mounting bracket. The output ends of the two hydraulic push rods are fixedly connected to the upper module. The lower module is attracted to the top of the magnetic fixing plate. A groove is opened on the lower module, and a sleeve is embedded in the groove.
[0012] Furthermore, the end of the long bolt and the anti-slip block are both located inside the sleeve, and the anti-slip block is inserted into the sleeve.
[0013] Furthermore, the threaded end of the long bolt passes through the protrusion, the mounting groove, and the nut, respectively.
[0014] Furthermore, the bottom dimensions of the magnetic fixing plate match the slot, and the bottom of the magnetic fixing plate is inserted into the slot.
[0015] Furthermore, the top of the base has two screw holes, and bolts are threaded into the screw holes.
[0016] Furthermore, the nut ends of the two bolts overlap with the outer surface of the magnetic fixing plate.
[0017] Furthermore, the upper module and the lower module are matched, and their center points are located on the same vertical line.
[0018] Furthermore, a retaining ring is fixedly sleeved at the end of the long bolt away from the lower module, and the end face of the retaining ring of the long bolt overlaps the outer surface of the protrusion.
[0019] A method for using a bending machine for sign processing includes the following steps: Step 1: Align the bottom of the magnetic fixing plate of the fixing component with the slot of the base component and insert it into the slot of the base component. Ensure that it is placed stably. Screw the two bolts into the screw holes on the top of the base until the nut ends are tightly attached to the outer surface of the magnetic fixing plate, thereby firmly locking the fixing component onto the base component.
[0020] Step 2: Place the lower module on the top center area of the magnetic fixing plate, place the sign blank to be bent on the lower module, rotate the long bolts on both sides to move them towards the center, and push the anti-sliding block at the end to press it tightly into the sleeve of the lower module. Through the friction between the anti-sliding block and the inner wall of the sleeve, the lower module is assisted in horizontal positioning and locking to prevent it from shifting during the bending process.
[0021] Step 3: Activate the hydraulic push rod to drive the upper module to move downwards in the vertical direction. The upper and lower modules cooperate with each other to work together on the nameplate blank between them to complete the bending operation. After the bending is completed, the hydraulic push rod retracts, driving the upper module to rise and reset.
[0022] Step 4: Rotate the long bolt in the opposite direction to disengage the anti-slip block from the sleeve, release the horizontal locking of the lower module, and remove the lower module along with the bent and shaped sign from the magnetic fixing plate to complete the unloading.
[0023] The present invention has the following beneficial effects: 1. This invention achieves "one-click" pre-positioning and quick placement of the lower module through magnetic attraction between the magnetic fixing plate and the lower module. The slot at the bottom of the magnetic fixing plate and the slot on the base are precisely matched to ensure that the initial positioning of the entire fixing component on the base is accurate, making the installation and positioning process of the mold simple and quick.
[0024] 2. This invention employs a multi-dimensional fixing scheme combining "vertical magnetic adsorption" and "lateral friction locking." The magnetic attraction provides stable vertical fixation, effectively overcoming the vertical impact and vibration generated when the upper module is pressed down. By rotating the long bolt, the anti-sliding block is tightly pressed into the sleeve of the lower module. The high friction coefficient rubber material and the inner wall of the sleeve generate enormous frictional force, achieving a firm lock of the lower module in the horizontal direction and eliminating the horizontal movement of the lower module caused by uneven stress on the blank during bending.
[0025] 3. By adopting a modular and standardized interface design, this invention allows for easy replacement of the lower module. Simply rotate the long bolt in the opposite direction to release the horizontal lock, and the lower module can be removed directly. After replacing the new module, the magnetic attraction will automatically complete the initial positioning, and then the horizontal lock can be tightened. The entire process does not require re-alignment or the use of additional tools. The fixing components themselves can also be quickly installed and fixed on the base through slots and side bolts, enabling quick switching between fixing components of different specifications or the entire bending unit. This enhances the equipment's ability to adapt to different processing needs and reduces production adjustment time and costs.
[0026] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] Please see Figure 1-8 The present invention provides a technical solution: a bending machine for sign processing, with an external electrical control box and a hydraulic system.
[0038] It includes a base assembly 1, a fixing assembly 2, and a mounting bracket 3.
[0039] The base assembly 1 includes a base 101, a slot 102 is provided at the middle of the top of the base 101, and two screw holes 103 are provided at the top of the base 101. Bolts 9 are threaded into the screw holes 103, and the nut ends of the two bolts 9 overlap with the outer surface of the magnetic fixing plate 201.
[0040] The fixing component 2 includes a magnetic fixing plate 201. Two protrusions 202 are formed on the top of both sides of the magnetic fixing plate 201. An installation groove 203 is provided on each protrusion 202, and a nut 204 is embedded and fixed within the installation groove 203. A long bolt 205 is threaded into the nut 204, and an anti-slip block 206 is fixedly connected to the end of the long bolt 205. Both the end of the long bolt 205 and the anti-slip block 206 are located within a sleeve 8. The anti-slip block 206 is inserted into the sleeve 8. The threaded end of the bolt 205 passes through the protrusion 202, the mounting groove 203 and the nut 204 respectively. The bottom specification of the magnetic fixing plate 201 matches the slot 102, and the bottom of the magnetic fixing plate 201 is inserted into the slot 102. A fixing ring is fixedly sleeved on the end of the long bolt 205 away from the lower module 6. The end face of the fixing ring of the long bolt 205 overlaps the outer surface of the protrusion 202 to prevent the long bolt (205) from being completely unscrewed out of the nut (204) when rotating, thus playing a limiting role.
[0041] Preferably, the magnetic fixing plate 201 is made of neodymium iron boron, and the anti-slip block 206 is made of rubber material with a high coefficient of friction.
[0042] Two hydraulic push rods 4 are fixedly installed on the bottom surface of the mounting bracket 3. The output ends of the two hydraulic push rods 4 are fixedly connected to the upper module 5. The top of the magnetic fixing plate 201 is attached to the lower module 6. The lower module 6 has a groove 7. A sleeve 8 is embedded in the groove 7. The upper module 5 and the lower module 6 are matched, and their center points are located on the same vertical line.
[0043] The bottom of the upper module (5) is a punch, and the top of the lower module (6) is provided with a V-shaped groove corresponding to the punch. By replacing the lower module with different angles, bending processing at different angles can be achieved.
[0044] A method for using a bending machine for sign processing includes the following steps: Step 1: Align the bottom of the magnetic fixing plate 201 of the fixing component 2 with the slot 102 of the base component 1, and insert it into the slot 102 of the base component 1 to ensure that it is placed stably. Screw the two bolts 9 into the screw holes 103 on the top of the base 101 until the nut ends are tightly attached to the outer surface of the magnetic fixing plate 201, thereby firmly locking the fixing component 2 onto the base component 1.
[0045] Step 2: Place the lower module 6 on the top center area of the magnetic fixing plate 201, place the sign blank to be bent on the lower module 6, rotate the long bolts 205 on both sides to move them towards the center, and push the anti-sliding block 206 at the end to press it tightly into the sleeve 8 of the lower module 6. Through the friction between the anti-sliding block 206 and the inner wall of the sleeve 8, the lower module 6 is assisted in horizontal positioning and locking, preventing it from shifting during the bending process.
[0046] Step 3: Start the hydraulic push rod 4 to drive the upper module 5 to move downwards in the vertical direction. According to the material and thickness of the nameplate blank, preset the downward parameters of the hydraulic push rod 4. The upper module 5 and the lower module 6 cooperate with each other to work together on the nameplate blank to complete the bending operation. After the bending is completed, the hydraulic push rod 4 retracts and drives the upper module 5 to rise and reset.
[0047] Step 4: Rotate the long bolt 205 in the opposite direction to disengage the anti-slip block 206 from the sleeve 8, release the horizontal locking of the lower module 6, and remove the lower module 6 together with the bent and formed nameplate from the magnetic fixing plate 201 to complete the unloading.
