Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy disc processing technology, and in particular to a clamping mechanism for aluminum alloy disc processing production. Background Technology

[0002] Aluminum alloy discs are widely used as housings for electronic appliances, bottle caps for daily chemical and pharmaceutical products, radiator covers for automobiles, partitions for aerospace, mold gaskets, ceiling panels for buildings, printed PS boards, and deep-drawn hardware components such as non-stick pans, pressure cookers, lampshades, and water heater housings due to their light weight, corrosion resistance, and excellent thermal and electrical conductivity. They are one of the deep-processed products with the largest downstream usage of aluminum alloy sheet and strip.

[0003] The mainstream industrial process for producing aluminum alloy discs is as follows: after uncoiling and leveling, aluminum alloy strip is continuously punched and blanked using a punch press and progressive dies to directly obtain discs of the required specifications. This method has high production efficiency and good material utilization, and has been widely used by aluminum plate processing enterprises both domestically and internationally.

[0004] However, during the punching process, the strip is continuously fed, and the instantaneous impact force of the die can reach tens of kilonewtons, causing the aluminum alloy coil to be easily moved by the force. Once the coil is misaligned, the punched disc will have defects such as burrs, ovals, and missing edges, resulting in the scrapping of the entire coil. This not only increases the waste of raw materials but also reduces the pass rate of subsequent deep-drawing products. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides a clamping mechanism for processing aluminum alloy discs, so as to solve the problem that defects such as burrs, ovals and missing edges of the discs are caused by the force displacement of the aluminum alloy coil during the punching process, which leads to waste of raw materials and a decrease in the qualified rate of deep-drawn finished products.

[0006] This utility model provides a clamping mechanism for processing aluminum alloy discs, including a worktable with a mounting hole on its upper surface. A lower mold is fixedly connected inside the mounting hole, and fixing components are provided at both ends of the worktable; it also includes:

[0007] A fixed conveying assembly is installed on the left and right sides of the workbench. The fixed conveying assembly is used to convey the roll material and limit its displacement.

[0009] Preferably, the fixing component includes multiple fixing seats, which are symmetrically arranged and fixed to the front and rear ends of the worktable by bolts. An installation block is fixed to the end of each fixing seat, and the self-locking motor is fixed to the front end of the right-side installation block.

[0010] Preferably, the fixed conveying assembly includes a pair of conveying shafts arranged vertically, both conveying shafts being rotatably supported on the same side mounting block, conveying rollers being fixedly connected to the side walls of the conveying shafts, and a clamping gap for the roll material to pass through is formed between the two conveying rollers, with gears fixedly connected to the rear ends of the upper and lower conveying shafts respectively, the two gears meshing with each other to achieve synchronous reverse rotation.

[0011] Preferably, each of the conveying rollers is covered with a rubber anti-slip layer on its outer periphery, and the two rear ends of the two conveying shafts located on the lower side are connected by a sprocket assembly. The output shaft of the self-locking motor is fixedly connected to the front end of the conveying shaft on the lower right side.

[0012] Preferably, the fixed conveying assembly further includes a limiting member, which includes a pair of threaded blocks. A reserved hole is provided at the center of the conveying shaft located on the upper side of the mounting block. An axial mounting hole is provided on the peripheral wall of the reserved hole. An clearance groove is provided inside the mounting block. A bidirectional threaded rod is rotatably connected inside the reserved hole. The threaded blocks are threadedly connected to the two side walls of the bidirectional threaded rod. The threaded blocks are located inside the mounting groove and are slidably connected thereto. A connecting rod is fixedly connected to the side wall of the threaded blocks. The end of the connecting rod passes through the clearance groove and is slidably connected thereto.

[0015] 1. This utility model, by setting fixed conveying components synchronously driven by self-locking motors on both sides of the workbench, and the upper and lower conveying rollers forming a constant clamping force on the roll material and restricting its lateral displacement, can completely eliminate the roll material movement caused by the impact force of the mold during high-speed punching, thereby avoiding defects such as burrs, ovals, and missing edges on the round sheet.

[0016] 2. This utility model, by covering the outer periphery of the conveyor roller with a rubber anti-slip layer and adding an adjustable limiting ring, can quickly adjust the double-sided limiting distance according to different widths of roll material, realizing "one machine for multiple specifications" production; at the same time, the self-locking motor self-locks when the power is cut off, and the roll material position can be fixed without the need for an additional braking device when the machine stops, which simplifies the operation process and reduces the equipment failure rate and maintenance costs.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figure 1-3 As shown, this utility model has the following two specific embodiments.

[0024] Example 1

[0025] A clamping mechanism for processing aluminum alloy discs includes a worktable 1, with a mounting hole 12 on the upper surface of the worktable 1. A lower mold 5 is fixedly connected inside the mounting hole 12. Fixing members 11 are provided at both the left and right ends of the worktable 1. The mechanism also includes:

[0026] Fixed conveyor assembly 2 is installed on the left and right sides of workbench 1. Fixed conveyor assembly 2 is used to convey roll material and limit its displacement.

[0027] The self-locking motor 3 is fixedly connected to the front end of the fixing part 11 on the right side of the workbench 1. The self-locking motor 3 is used to drive the fixed conveying assembly 2.

[0028] The fastener 11 includes multiple fixing seats 111, which are symmetrically arranged and fixed to the front and rear ends of the workbench 1 with bolts. The fixing seat 111 has a mounting block 112 fixed at its end, and the self-locking motor 3 is fixed to the front end of the right mounting block 112.

[0029] Support legs 6 are fixedly connected to the four corners of the lower end of the workbench 1, and chamfers 13 are opened on both the left and right ends of the workbench 1.

[0030] In this embodiment, as Figures 1-2 As shown, the chamfer 13 at the left and right ends of the worktable 1 is 45°. The chamfered edges are deburred and coated with anti-rust paint to form a smooth transition for the roll material inlet and outlet. The fixed conveying components 2 at the left and right ends of the worktable 1 are mounted in the mounting block 112 via bearing seats, so that the roll material can be continuously clamped and restricted under the drive of the self-locking motor 3, and the strip material in the punching area is always centered and stable.

[0031] Example 2

[0032] The difference from Embodiment 1 is that this embodiment discloses a fixed conveying assembly 2;

[0033] The fixed conveying assembly 2 includes a pair of conveying shafts 21 arranged vertically. Both conveying shafts 21 are rotatably supported on the same side mounting block 112. Conveying rollers 22 are fixedly connected to the side walls of the conveying shafts 21, and a clamping gap for the roll material to pass through is formed between the two conveying rollers 22. Gears 23 are fixedly connected to the rear ends of the upper and lower conveying shafts 21 respectively. The two gears 23 mesh with each other to achieve synchronous reverse rotation.

[0034] Each conveyor roller 22 is covered with a rubber anti-slip layer on its outer periphery. The two conveyor shafts 21 located on the lower side are connected by a sprocket assembly 4. The output shaft of the self-locking motor 3 is fixedly connected to the front end of the lower right conveyor shaft 21.

[0035] The fixed conveying assembly 2 also includes a limiting member 24, which includes a pair of threaded blocks 243. A reserved hole 211 is provided on the axis of the conveying shaft 21 located on the upper side of the mounting block 112. An axial mounting hole 12 is provided on the peripheral wall of the reserved hole 211. An avoidance groove 213 is provided inside the mounting block 112. A bidirectional threaded rod 241 is rotatably connected inside the reserved hole 211. The threaded blocks 243 are threadedly connected to the two side walls of the bidirectional threaded rod 241. The threaded blocks 243 are located inside the mounting groove 212 and are slidably connected thereto. A connecting rod 244 is fixedly connected to the side wall of the threaded blocks 243. The end of the connecting rod 244 passes through the avoidance groove 213 and is slidably connected thereto. A limiting ring 245 is fixedly connected to the end of the connecting rod 244. The limiting ring 245 is sleeved on the side wall of the conveying roller 22 and is slidably connected thereto. A drive handle 242 is fixedly connected to the front side wall of the bidirectional threaded rod 241.

[0036] In this embodiment, as Figures 2-3As shown, after the self-locking motor 3 is energized, its output shaft directly drives the right lower conveyor shaft 21 to rotate. The rotation of this lower conveyor shaft 21 drives the left lower conveyor shaft 21 to rotate through the sprocket assembly 4, causing the left and right lower conveyor rollers 22 to rotate at the same speed. At the same time, the rear ends of each side's upper and lower conveyor shafts 21 are engaged by gears 23, causing the lower conveyor shaft 21 to rotate and the upper conveyor shaft 21 to rotate in the opposite direction. The upper and lower conveyor rollers 22 thus form a pair of clamping rollers with the same rotation speed but opposite directions, continuously feeding the roll material towards the mold. The rubber anti-slip layer on the outer periphery of the conveyor rollers 22 increases the contact area with the surface of the roll material under the action of elastic deformation. To prevent slippage; when the width of the roll material changes, the drive handle 242 is turned by hand, and the bidirectional threaded rod 241 rotates accordingly. The threaded blocks 243 on both sides can only move axially to center due to the circumferential limit of the mounting groove 212. The connecting rod 244 drives the limiting ring 245 to slide on the surface of the conveying roller 22, so that the distance between the two limiting rings 245 on both sides matches the width of the roll material, and the lateral positioning is achieved. After the self-locking motor 3 is de-energized, it immediately enters the self-locking state, the conveying shaft 21 stops rotating and maintains its position, preventing the roll material from retreating due to the rebound force, and ensuring that the strip material is always in a clamped, centered and non-offset state at the moment of punching.

[0037] The working principle of this utility model is as follows:

[0038] The aluminum alloy coil is first clamped by the fixed conveyor assembly 2, then passes over the chamfer 13 of the worktable 1 and enters the punching area of ​​the lower die 5. The self-locking motor 3 drives the right lower conveyor shaft 21 to rotate, which synchronously drives the left lower conveyor shaft 21 through the sprocket assembly 4, so that the two lower conveyor rollers 22 rotate at the same speed. At the same time, the rear gear 23 forces the upper conveyor shaft 21 to rotate in the opposite direction, forming a roller clamping and continuously feeding the coil into the punching area of ​​the lower die 5. The conveyor rollers 22 are covered with a rubber anti-slip layer, which increases the friction under elastic deformation to prevent the coil from slipping. Slippage; the limiting component 24 drives the bidirectional threaded rod 241 through the rotating drive handle 242, so that the threaded blocks 243 on both sides move in the center. The distance between the limiting rings 245 is adjusted by the connecting rod 244, thereby achieving lateral limiting for rolls of different widths; the self-locking motor 3 self-locks when the power is cut off, the conveyor shaft 21 stops immediately and locks its position, preventing the roll from retracting, ensuring that the roll is always in a stable state of clamping, centering and no deviation when the punch press punches instantly, eliminating defects such as burrs, ovals and missing edges caused by the strip movement.

[0039] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
