Description

Technical Field

[0001] The utility model relates to the technical field of honeycomb aluminum plate processing, in particular to a honeycomb aluminum plate punching device. Background Art

[0002] The honeycomb aluminum plate punching device is a device specially used for punching holes on honeycomb aluminum plates. The punched aluminum honeycomb plate is a small hole punched out on the surface of the aluminum honeycomb plate according to a certain pattern. The honeycomb aluminum plate is mainly due to its unique honeycomb structure, which makes the aluminum plate have high strength and stability. It is not only beautiful, but also the sound-absorbing paper hidden inside has a very good absorption effect. It is particularly suitable for applications with high requirements for the strength and stability of the aluminum plate.

[0003] The punching device on the existing punching machine is an integrated setting and cannot be replaced. It can only punch a single hole on the honeycomb aluminum plate. When it is necessary to punch holes of other sizes or shapes on the honeycomb aluminum plate, other punching equipment has to be replaced.

[0005] In response to the above problems, the solution given in the existing patent is to replace the punching tool by setting a detachable structure to facilitate the processing of honeycomb aluminum plates of different sizes. However, during the punching process, due to the friction between the plate and the punching tool, the plate after punching is easily stuck on the punch and needs to be manually removed, which reduces the punching efficiency. Summary of the invention

[0006] The purpose of the utility model is to provide a honeycomb aluminum plate punching device, which can make the pressing block contact with the upper surfaces of the two ends of the honeycomb aluminum plate when punching the honeycomb aluminum plate, so as to press the honeycomb aluminum plate. Since the spring has its own tension after being compressed, the lower end of the limit plate and the pressing block are in contact with the upper surface of the honeycomb aluminum plate to press the honeycomb aluminum plate, thereby avoiding the honeycomb aluminum plate from being easily stuck on the punching knife due to the friction force when the punching knife is reset, so as to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a honeycomb aluminum plate punching device, comprising a device frame, a hydraulic cylinder is fixed to the upper surface of the device frame by bolts, and a punching mechanism for processing the honeycomb aluminum plate is fixed to the telescopic end of the hydraulic cylinder through the device frame;

The ends of the springs are abutted and connected with limit blocks that are slidably connected to the installation grooves. A connecting plate is fixed to the lower surface of the limit block, and a limit plate is fixed to the lower surface of the connecting plate. Two clamping blocks are fixed to the lower surface of the limit plate.

[0009] Preferably, a plurality of cleaning holes are opened inside the limiting plate, and punching knives equidistantly fixed on the stamping part are movably connected inside the cleaning holes.

[0010] Preferably, two limiting grooves are provided inside the device frame, and clamping plates are arranged on the inner walls of the two limiting grooves.

[0013] Preferably, clamping blocks are fixed on both sides of the collection box, and the outer surface of the clamping block is slidably connected to a clamping groove provided on the inner wall of the device frame.

[0014] Preferably, the outer surface of the device frame is provided with limit screws abutting against the collection box.

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

[0016] 1. Through the punching mechanism, when punching the honeycomb aluminum plate, the pressing block can be in contact with the upper surface of both ends of the honeycomb aluminum plate to press the honeycomb aluminum plate. Since the spring has tension after being compressed, the lower end of the limit plate and the pressing block are in contact with the upper surface of the honeycomb aluminum plate to press the honeycomb aluminum plate, thereby preventing the honeycomb aluminum plate from being easily stuck on the punching knife due to friction when the punching knife is reset;

[0017] 2. By unscrewing the set limit screws, the fixation of the collection box is released, the collection box can be disassembled, and the collected waste can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] The utility model provides a technical solution:

[0027] See also Figures 1 to 4 A honeycomb aluminum plate punching device comprises a device frame 1, a hydraulic cylinder 2 is fixed to the upper surface of the device frame 1 by bolts, and a punching mechanism for processing the honeycomb aluminum plate is fixed at the telescopic end of the hydraulic cylinder 2 which penetrates the device frame 1;

[0028] The punching mechanism includes a stamping part 3, which is fixed to the telescopic end of the hydraulic cylinder 2 by bolts. Two installation grooves 31 are provided inside the stamping part 3, and springs 32 are installed inside the two installation grooves 31. The ends of the springs 32 are abutted and connected with limit blocks 33 that are slidably connected to the installation grooves 31. A connecting plate 34 is fixed to the lower surface of the limit block 33, and a limiting plate 35 is fixed to the lower surface of the connecting plate 34. Two clamping blocks 38 are fixed to the lower surface of the limit plate 35. A plurality of cleaning holes 36 are provided inside the limit plate 35, and a punching knife 37 equidistantly fixed on the stamping part 3 is movably connected inside the cleaning holes 36.

[0029] By adopting the above technical solution, before using the honeycomb aluminum plate punching device, the device frame 1 is first placed in a suitable position, and the hydraulic cylinder 2 is set to drive the stamping part 3 to move vertically, so that the limit plate 35 moves. At this time, the clamping block 38 on the limit plate 35 contacts the upper surface of the two ends of the honeycomb aluminum plate, thereby pressing the honeycomb aluminum plate, and the stamping part 3 continues to move vertically. Through the spring 32 set in the installation groove 31, the connecting plate 34 can drive the limit block 33 to slide in the installation groove 31, thereby pushing the spring 32 to compress, and through the limit plate The cleaning hole 36 on 35 allows the punching knife 37 to pass through the limiting plate 35 to punch the honeycomb aluminum plate at the lower end. The waste generated by the punching will fall into the collection box 8 below. After the punching is completed, the hydraulic cylinder 2 drives the stamping part 3 to reset. Since the spring 32 has its own tension after being compressed, the spring 32 pushes the connecting plate 34, so that the lower end of the limiting plate 35 and the clamping block 38 are in contact with the upper surface of the honeycomb aluminum plate, pressing the honeycomb aluminum plate, thereby avoiding the honeycomb aluminum plate from being easily stuck on the punching knife 37 due to the friction when the punching knife 37 is reset.

[0030] Specifically, Figure 1-Figure 4 As shown, two limit grooves 4 are provided inside the device frame 1, and the inner walls of the two limit grooves 4 are provided with clamping plates 5, and the side walls of the clamping plates 5 are connected with clamping electric cylinders 6 fixedly connected to the device frame 1, and the clamping plates 5 and the clamping electric cylinders 6 form a telescopic structure, and a fixing bolt 7 is installed at the lower end of the device frame 1, and a collecting box 8 is provided at the lower end of the device frame 1, and blocks 9 are fixed on both sides of the collecting box 8, and the outer surface of the block 9 is slidably connected with a slot 10 provided on the inner wall of the device frame 1, and a limit screw 11 abutting against the collecting box 8 is installed on the outer surface of the device frame 1.

[0031] By adopting the above technical solution, the device frame 1 can be fixed by the fixing bolts 7 arranged on the device frame 1. When in use, the honeycomb aluminum plate to be processed is placed in the limiting groove 4, and the clamping electric cylinder 6 is started to drive the clamping plate 5 to move, so as to limit the honeycomb aluminum plate. By unscrewing the limiting screws 11 on the device frame 1, the fixation of the collection box 8 can be released. With the cooperation of the clamping block 9 and the clamping groove 10, the collection box 8 can be disassembled and the collected waste can be recycled.

[0032] Working principle: the clamping electric cylinder 6 drives the clamping plate 5 to move, thereby limiting the position of the honeycomb aluminum plate. The hydraulic cylinder 2 drives the stamping part 3 to move vertically, so that the limit plate 35 moves. The pressing block 38 on the limit plate 35 contacts the upper surface of both ends of the honeycomb aluminum plate to press the honeycomb aluminum plate, while the stamping part 3 continues to move vertically. Through the spring 32 set in the installation groove 31, the connecting plate 34 can drive the limit block 33 to slide in the installation groove 31, pushing the spring 32 to compress, and through the cleaning hole 36 on the limit plate 35, the punching knife 37 passes through the limit plate 35 to punch the honeycomb aluminum plate at the lower end. Hole operation, the waste generated by punching will fall into the collection box 8 below. After punching is completed, the hydraulic cylinder 2 drives the stamping part 3 to reset. Since the spring 32 has its own tension after being compressed, the lower end of the limit plate 35 and the clamping block 38 are in contact with the upper surface of the honeycomb aluminum plate, and the honeycomb aluminum plate is pressed to prevent the honeycomb aluminum plate from being easily stuck on the punching knife 37 due to the friction when the punching knife 37 is reset. The limit screw 11 on the device frame 1 can be unscrewed to release the fixation of the collection box 8. With the cooperation of the clamping block 9 and the clamping slot 10, the collection box 8 can be disassembled and the collected waste can be recycled.

Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
