Description

Technical Field

[0001] This utility model relates to the field of aluminum single-panel processing technology, and in particular to an aluminum single-panel punching device. Background Technology

[0002] Aluminum panels have become the preferred decorative material for curtain wall art designs due to their lightweight, easy installation, high plasticity, safety, and durability. To meet the needs of architectural expression and acoustic and ventilation functions, the panels need to be punched in a large number of arrays in the factory. The quality and efficiency of punching directly determine the appearance and construction period of the curtain wall.

[0003] Existing punching equipment all adopts a "upper die-lower die" pairing structure: the upper die is locked to the bottom of the slider by bolts or pressure plates, and the lower die is embedded in the positioning groove of the worktable; when the hole spacing, hole diameter or arrangement changes, the whole machine must be stopped, and the mold bolts must be removed one by one by manual labor with the help of wrenches, pry bars and other tools, and then the new mold is hoisted and re-aligned and locked.

[0004] However, the above-mentioned mold-changing method has obvious drawbacks in actual production: when there are many bolts and the space is small, a lot of time will be spent in the disassembly and assembly process, thereby reducing production efficiency. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, this utility model provides an aluminum single-panel punching device to solve the problems of long mold change cycle, excessive manual intervention and low production efficiency.

[0006] This utility model provides an aluminum single-panel punching device, including a workbench, a mounting base fixedly connected to the upper end of the workbench, a supporting mold placed inside the mounting base, supporting columns fixedly connected to the four corners of the upper end of the workbench, a top plate fixedly connected to the upper end of the supporting columns, a hydraulic cylinder fixedly connected inside the top plate, a fixed seat fixedly connected to the output shaft end of the hydraulic cylinder, and a lower mold provided at the lower end of the fixed seat; it also includes:

[0007] A locking assembly is symmetrically installed at both ends of the fixed base, and the locking assembly is used to fix the upper mold to the lower end of the fixed base;

[0008] A drive mechanism is installed at the lower end of the top plate. The drive mechanism is used to drive the locking assembly to release the upper mold, so that it is disengaged from the fixed seat.

[0009] Preferably, slide rails are symmetrically fixedly connected to the left and right sides of the lower end of the fixed base, and limit strips are fixedly connected to both ends of the upper mold. The limit strips are located inside the slide rails and are slidably connected to them. Pin holes are opened at both ends of the upper mold.

[0010] Preferably, the locking assembly includes a pin, and the upper surfaces of both sides of the fixing seat are provided with sliding holes. A spring is fixedly connected inside the sliding hole, and a drive plate is fixedly connected to the adjacent end of the spring. The drive plate is located inside the sliding hole and is slidably connected thereto. The pin is fixedly connected to the adjacent ends of the two drive plates. The adjacent ends of the two pins pass through the slide rail and are slidably connected thereto. The pin ends are located inside the pin holes and are inserted into each other.

[0011] Preferably, the drive mechanism includes a pair of bidirectional threaded rods, which are rotatably connected to the left and right sides of the lower end of the top plate via bearing seats. Both ends of the bidirectional threaded rods are threadedly connected to threaded blocks. The upper end of the threaded block is slidably connected to the lower end of the top plate. The end of the threaded block near the hydraulic cylinder is rotatably connected to a first connecting rod. The first connecting rods on the same side are rotatably connected to each other via connecting blocks. The connecting blocks cooperate with the drive plate. The drive mechanism also includes a limit assembly.

[0012] Preferably, a motor is fixedly connected to the lower end of the top plate, and the output shaft of the motor is fixedly connected to the front end of a bidirectional threaded rod located on the left side of the top plate. The two bidirectional threaded rods are connected by a sprocket assembly.

[0013] Preferably, the limiting component includes a slider, and a pair of sliders are provided, which are symmetrically slidably connected to the left and right sides of the lower end of the top plate. A second connecting rod is rotatably connected to the side wall of the slider. The end of the second connecting rod away from the slider is rotatably connected to the side wall of the threaded block on the front side of the top plate. A connecting rod is fixedly connected to the lower end of the slider. A limiting rod is fixedly connected to the lower end of the connecting rod. The limiting rod passes through the mounting base, and the rear ends of the two limiting rods on adjacent sides abut against the front end of the supporting mold.

[0014] Preferably, the front end of the workbench is provided with a discharge trough, which extends through to the upper end of the mounting base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This utility model uses a motor to drive a bidirectional threaded rod to rotate, causing the second connecting rod and connecting block to expand outward. When the connecting block expands outward, it will abut against the driving block and drive the driving block to move, causing the pin to exit the pin hole. At this time, the upper module can be pulled out from the lower end of the fixed base. Then, after the new mold is pushed in along the slide rail, the motor drives the bidirectional threaded rod to rotate in the opposite direction. At this time, the spring automatically resets, the pin locks again, and the limit rod springs back to press. The positioning and clamping are completed in one action, thereby shortening the mold change time.

[0017] 2. When the threaded block expands outward, it works with the second connecting rod to move the slider, which in turn moves the limiting rod fixed on the connecting rod, so that the limiting rod needs to abut against the supporting mold, thereby facilitating the replacement of the supporting mold.

Detailed Implementation

[0025] 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.

[0026] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0027] Example 1

[0028] A punching device for aluminum single-panel panels includes a workbench 1, a mounting base 11 fixedly connected to the upper end of the workbench 1, a support mold 2 placed inside the mounting base 11, support columns 3 fixedly connected to the four corners of the upper end of the workbench 1, a top plate 4 fixedly connected to the upper end of the support columns 3, a hydraulic cylinder 41 fixedly connected inside the top plate 4, a fixed seat 5 fixedly connected to the output shaft end of the hydraulic cylinder 41, and a lower mold provided at the lower end of the fixed seat 5; it also includes:

[0029] Locking assembly 53 is symmetrically installed at the left and right ends of the fixed base 5. Locking assembly 53 is used to fix the upper mold 6 to the lower end of the fixed base 5.

[0030] The drive mechanism is installed at the lower end of the top plate 4. The drive mechanism is used to drive the locking assembly 53 to release the upper mold 6, so that it is separated from the fixed seat 5.

[0031] The front end of the workbench 1 is provided with a discharge groove 12, which extends through to the upper end of the mounting base 11;

[0032] The lower end of the fixed base 5 is symmetrically fixedly connected to the left and right sides of the slide rail 51. The upper mold 6 has a limit strip 61 fixedly connected to both ends of the left and right sides. The limit strip 61 is located inside the slide rail 51 and is slidably connected to it. The upper mold 6 has pin holes 62 on both ends of the left and right sides.

[0033] The locking assembly 53 includes a pin 531. Sliding holes 52 are provided on the upper surfaces of both sides of the fixed base 5. A spring 533 is fixedly connected inside the sliding hole 52. A drive plate 532 is fixedly connected to the adjacent end of the spring 533. The drive plate 532 is located inside the sliding hole 52 and is slidably connected thereto. The pin 531 is fixedly connected to the adjacent ends of the two drive plates 532. The adjacent ends of the two pins 531 pass through the slide rail 51 and are slidably connected thereto. The ends of the pins 531 are located inside the pin holes 62 and are inserted into each other.

[0034] In this embodiment, as Figures 1-4As shown, the mounting base 11 is centered. After the support mold 2 is placed from top to bottom, its outer edge fits against the side wall of the mounting base 11, achieving initial planar positioning. When the piston of the hydraulic cylinder 41 retracts, the fixed base 5 rises to its highest position. Activating the drive mechanism will, on the one hand, cancel the contact of the support mold 2; on the other hand, it will drive the drive plate 532 in the locking assembly 53 to move. The movement of the drive plate 532 will drive the pin 531 to move, causing the pin 531 to dislodge from the pin hole 62. At this time, the upper mold 6 can be pulled out from the slide rail 51, and then the new upper mold 6 can be pulled along the slide rail 51. Push it horizontally until the rear end of the limit bar 61 abuts against the stop of the slide rail 51 to complete the sliding positioning; at this time, the pin hole 62 and the pin 531 axis coincide, and the drive mechanism is activated, so that the drive mechanism cancels the abutment of the locking component 53, thereby releasing the spring 533 in the locking component 53, driving the drive plate 532 to move. The movement of the drive plate 532 causes the pin 531 to extend into the pin hole 62, and the upper mold 6 is suspended and locked; thus, the replacement of another mold of a different specification is completed without the need for auxiliary tools; the waste material after punching is automatically discharged from the worktable 1 through the discharge groove 12.

[0035] Example 2

[0036] The difference from Embodiment 1 is that this embodiment discloses a drive mechanism;

[0037] The drive mechanism includes a pair of bidirectional threaded rods 71, which are rotatably connected to the left and right sides of the lower end of the top plate 4 via bearing seats. Both ends of the bidirectional threaded rods 71 ​​are threadedly connected to threaded blocks 73. The upper end of the threaded blocks 73 is slidably connected to the lower end of the top plate 4. The end of the threaded blocks 73 near the hydraulic cylinder 41 is rotatably connected to a first connecting rod 74. The first connecting rods 74 on the same side are rotatably connected to each other via connecting blocks 75. The connecting blocks 75 cooperate with the drive plate 532. The drive mechanism also includes a limit assembly 76.

[0038] A motor 77 is fixedly connected to the lower end of the top plate 4. The output shaft end of the motor 77 is fixedly connected to the front end of the bidirectional threaded rod 71 located on the left side of the top plate 4. The two bidirectional threaded rods 71 ​​are connected by a sprocket assembly 72.

[0039] The limiting component 76 includes a slider 761. A pair of sliders 761 are provided and are symmetrically slidably connected to the left and right sides of the lower end of the top plate 4. A second connecting rod 762 is rotatably connected to the side wall of the slider 761. The end of the second connecting rod 762 away from the slider 761 is rotatably connected to the side wall of the threaded block 73 on the front side of the top plate 4. A connecting rod 763 is fixedly connected to the lower end of the slider 761. A limiting rod 764 is fixedly connected to the lower end of the connecting rod 763. The limiting rod 764 passes through the mounting base 11. The rear ends of the adjacent side of the two limiting rods 764 abut against the front end of the supporting mold 2.

[0040] In this embodiment, as Figure 2 and Figure 5 As shown, after the motor 77 starts, the left bidirectional threaded rod 71 rotates, which drives the right bidirectional threaded rod 71 to rotate synchronously via the sprocket assembly 72; the front and rear threaded blocks 73 move towards each other due to the guidance of the top plate 4, the first connecting rod 74 moves and drives the connecting block 75 to move outward, the connecting block 75 moves and abuts against the drive plate 532 and drives the drive plate 532 to move, so that the pin 531 exits the pin hole 62, and at the same time the second connecting rod 762 moves forward with the front threaded block 73, pulling the slider 761 and driving the limit rod 764 away from the support mold 2, thereby canceling the limit fixation of the support mold 2; when the motor 77 reverses, each component returns to its position in sequence, the pin 531 is reinserted into the pin hole 62 through the spring 533, and the limit rod 764 abuts against the front end of the support mold 2 again, completing one release-locking cycle.

[0041] The working principle of this utility model is as follows:

[0042] Hydraulic cylinder 41 first lifts fixed seat 5 to its highest position, motor 77 is energized and rotates, bidirectional threaded rods 71 ​​on both sides rotate synchronously, and front and rear threaded blocks 73 expand towards each other; first connecting rod 74 pushes connecting block 75 outward, causing connecting block 75 to press drive plate 532, compress spring 533 and cause pin 531 to exit pin hole 62 of upper mold 6, at the same time the second connecting rod 762 pulls slider 761 forward, limit rod 764 disengages from supporting mold 2, and both upper mold 6 and supporting mold 2 are released; this The original upper mold 6 is pulled out horizontally along the slide rail 51, and then the new upper mold 6 is pushed in until the limit bar 61 abuts against the stop of the slide rail 51. The motor 77 reverses and all components return to their original positions: the spring 533 pushes the drive plate 532 to reset, the pin 531 is inserted into the pin hole 62 of the new mold, and the limit rod 764 tightens the support mold 2 again, completing the quick mold change; then the hydraulic cylinder 41 descends, the upper mold 6 is pressed down with the fixed seat 5, and together with the support mold 2, the aluminum plate is punched, and the waste material automatically slides down through the discharge groove 12.

[0043] 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.
