Description

Technical Field

[0001] This utility model relates to the field of stainless steel cabinet processing technology, specifically a laser cutting device for security cabinets. Background Technology

[0002] As a type of secure storage cabinet, the outer shell of a security cabinet is usually made of thick stainless steel plate. For some security cabinets with special storage purposes, in order to prevent the entire cabinet from being stolen, it is usually necessary to embed the cabinet in the side wall. In this case, holes need to be drilled in the side wall of the cabinet, and then the anchors are installed from the inside of the cabinet, thereby preventing non-destructive disassembly and theft from the outside.

[0003] When cutting cabinets made of thick steel plates, YAG laser cutting machines are usually used because they have higher energy density and can effectively penetrate steel plates. However, this also means that thicker steel plates will produce more cutting debris during the actual cutting process. Some of this debris enters the cabinet and damages the inner wall, making it difficult to perform secondary grinding and polishing maintenance. At the same time, if the laser energy is not adjusted accurately or the steel plate thickness is inconsistent, penetrating cuts can easily occur, damaging the other side of the inner wall of the cabinet. Therefore, a laser cutting device for security cabinets is specially provided. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] This application provides a laser cutting device for security cabinets, which solves the problem that in the actual cutting process, thicker steel plates will produce more cutting debris, some of which will enter the cabinet and cause damage to the inner wall, making it inconvenient to perform secondary grinding and polishing maintenance. At the same time, when the laser energy is not adjusted accurately or the steel plate thickness is inconsistent, penetrating cuts are likely to occur, causing damage to the other side of the inner wall of the cabinet.

[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] This utility model discloses a laser cutting device for security cabinets.

[0027] According to the appendix Figure 1-4 As shown, the device includes a cutting table 1 and a laser cutting machine 2 mounted on the cutting table 1. The laser cutting machine 2 includes X-axis linear motors 21 fixedly mounted on the top of both sides of the cutting table 1, and a Y-axis linear motor 22 installed between the two sets of X-axis linear motors 21. A YAG laser cutting head 23 is mounted on the mover of the Y-axis linear motor 22.

[0028] Start the laser cutting machine 2, so that the mover on the X-axis linear motor 21 drives the Y-axis linear motor 22 to move vertically, and the mover on the Y-axis linear motor 22 drives the YAG laser cutting head 23 to move horizontally, so that the YAG laser cutting head 23 can move and stop at any position on the horizontal plane. The YAG laser cutting head 23 emits a high-energy laser beam to cut the thick steel plate.

[0029] The cutting table 1 has a workpiece positioning component 3 inside one end. The workpiece positioning component 3 includes a hydraulic lifting platform 31 fixedly installed in the middle of the front end of the cutting table 1. Clamping and positioning cylinders 32 are provided on both sides of the hydraulic lifting platform 31, and the clamping and positioning cylinders 32 are embedded in the side wall of the cutting table 1. A rubber pressure plate 33 is fixedly installed at the output end of the clamping and positioning cylinders 32.

[0030] Place the cabinet to be cut on the hydraulic lifting platform 31 with the side to be cut facing upwards and the open end of the cabinet facing the laser cutting machine 2. Then activate the clamping and positioning cylinders 32 on both sides, so that the output end of the clamping and positioning cylinders 32 drives the rubber pressure plate 33 to press on both sides of the cabinet to fix the cabinet.

[0031] The other end of the cutting table 1 is equipped with a cutting protection assembly 4. The cutting protection assembly 4 includes a mounting strip 41, a suspension arm 42, a material collection hood 43, a connecting pipe 44, a suspension base 45, an adjusting cylinder 46, a positioning shaft 47, a metal flexible hose 48, and a negative pressure collection box 49. The suspension arm 42 is raised and lowered at the bottom of the laser cutting machine 2. The mounting strip 41 is fixedly installed at the bottom of the YAG laser cutting head 23. The material collection hood 43 is installed on the suspension arm 42, facing the output end of the YAG laser cutting head 23, and is made of thick ceramic material. The negative pressure collection box 49 is fixedly installed at the end of the cutting table 1, and is connected to the material collection hood 43. The connection is used for negative pressure collection of waste generated during the cutting process. An adjusting cylinder 46 is fixedly installed at the end of the mounting strip 41. The output end of the adjusting cylinder 46 is fixedly connected to the end of the suspension arm 42. A connecting pipe 44 is fixedly installed at the bottom of the suspension arm 42. The two ends of the connecting pipe 44 are respectively connected to the collection hood 43 and the negative pressure collection box 49. Suspension seats 45 for fixing the connecting pipe 44 are installed at the bottom of both ends of the suspension arm 42. A positioning shaft 47 is fixedly welded to the top of a set of suspension seats 45 at the end of the suspension arm 42. The positioning shaft 47 movably passes through the mounting strip 41. A metal hose 48 is installed between the end of the connecting pipe 44 and the negative pressure collection box 49.

[0032] The negative pressure collection box 49 is assembled with a negative pressure fan and a sealed cabinet. The negative pressure fan draws the air inside the sealed cabinet outward, creating a negative pressure inside, which in turn generates negative pressure suction in the collection hood 43, thus achieving pneumatic collection of debris.

[0033] An integrated control switch 5 is installed on the cutting table 1. The integrated control switch 5 is connected to the laser cutting machine 2, the workpiece positioning component 3 and the cutting protection component 4. Through multiple control switches set on the integrated control switch 5, multiple electrical components in the device are controlled to start and stop in a coordinated manner.

[0034] Working principle: When using this device, the cabinet to be cut is placed on the hydraulic lifting platform 31 with the side to be cut facing upwards and the open end of the cabinet facing the laser cutting machine 2. Then, the clamping and positioning cylinders 32 on both sides are activated, causing the output ends of the clamping and positioning cylinders 32 to drive the rubber pressure plates 33 to press against both sides of the cabinet, fixing the cabinet. At this time, the laser cutting machine 2 is started, causing the mover on the X-axis linear motor 21 to drive the Y-axis linear motor 22 to move, so that the YAG laser cutting head 23 moves to the top of the workpiece. At the same time, the material collection hood 43 moves with the YAG laser cutting head 23 into the cabinet. Then, the cylinder 46 is adjusted. When activated, the material collection hood 43 moves upward and close to the top wall of the cabinet. At this time, the negative pressure collection box 49 starts, generating negative pressure to suck up debris. Simultaneously, the YAG laser cutting head 23 moves under the combined movement of the X-axis linear motor 21 and the Y-axis linear motor 22. During the movement, the YAG laser cutting head 23 cuts the top wall of the cabinet. The debris generated by the cutting falls directly into the material collection hood 43. Then, under the action of negative pressure airflow, it enters the interior of the negative pressure collection box 49 along the connecting pipe 44 and the metal hose 48. At the same time, the material collection hood 43 blocks the laser beam to prevent excessive laser beam from penetrating the top wall of the cabinet and causing damage to the interior of the cabinet.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
