Description

Technical Field

[0001] This utility model relates to the field of trolley case manufacturing and processing technology, specifically to a sheet metal cutting device for trolley case manufacturing and processing. Background Technology

[0002] When producing trolley cases, the raw sheet material needs to be cut into specific sizes and shapes according to design requirements. The sheet material cutting device uses an electrically driven circular saw blade or band saw blade for cutting, while thinner sheet materials can also be cut with a tool similar to a guillotine. Both of these methods can cause accidental injury to operators to some extent when used.

[0003] Although some equipment has a safety emergency stop device, it needs to be triggered manually. If the operation is improper or the inertial force of the cutting blade is too great during use, the equipment may not be able to stop and the danger may not be eliminated in time, thus failing to effectively protect the safety of the operator. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a sheet metal cutting device for the production and processing of trolley cases, which has advantages such as good safety and solves the problem that improper operation or excessive inertial force of the cutting blade can prevent the equipment from stopping and the danger from being eliminated in time.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of high safety, this utility model provides the following technical solution: a sheet metal cutting device for trolley case production and processing, including a sheet metal cutting table, a slide rail frame bolted to the upper surface of the sheet metal cutting table, and a safety cutting component located on the slide rail frame. The safety cutting component is used to ensure the safe cutting of sheet metal during trolley case production and processing.

[0008] Preferably, an anti-injury protection component is located on the sheet metal cutting table and is used to prevent workers' hands from being accidentally injured when cutting sheet metal.

[0009] Preferably, the safety cutting component includes a slider that is slidably connected to a slide rail frame. A first fixing post is welded and fixed to the lower surface of the slider. A gear is fixedly sleeved on the outer surface of the first fixing post. A rack is bolted to the outer surface of the slide rail frame.

[0010] Preferably, the gear meshes with the rack, a fixing frame is welded to the right surface of the slider, and a second fixing column is fixedly connected between the fixing frame and the slider.

[0011] Preferably, a gear disk is fixedly sleeved on the outer surface of the second fixed column, the gear disk meshes with a gear, an internal gear ring is provided on the right side of the gear disk, and a sliding groove is milled on the outer surface of the fixed frame.

[0012] Preferably, a small slider is slidably connected inside the groove, a spring is fixedly connected between the bottom wall of the groove and the small slider, and a movable shaft is rotatably connected inside the small slider.

[0013] Preferably, a cutting blade is fixedly installed on the outer surface of the movable shaft, and both ends of the movable shaft rotate through the outer surface of the small slider. A small gear is fixedly sleeved at one end of the movable shaft that extends into the internal gear ring, and the small gear is adapted to the internal gear ring.

[0014] Preferably, the anti-accidental injury protection component includes a glove, which is rotatably connected to the outer surface of the movable shaft by a bearing. A hand guard is integrally formed on the end of the glove near the cutting blade. The hand guard is D-shaped, which makes the center of gravity of the entire anti-accidental injury protection component higher. Under normal circumstances, the complete arc part on the hand guard will automatically rotate downward under its own weight, avoiding the tragedy of the cutting blade injuring the hand when no cutting operation is being performed. A hand guard plate is bolted to the outer surface of the hand guard plate. The hand guard plate can protect the worker's thumb from being accidentally injured by the cutting blade when using the sheet metal cutting device.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a sheet metal cutting device for the production and processing of trolley cases, which has the following beneficial effects:

[0017] 1. This sheet metal cutting device for trolley case manufacturing aligns and fixes the cutting edge of the thin sheet metal to be cut on the cutting table with the cutting blade. Then, manually pressing down the handle causes the small slider and cutting blade to move downwards, compressing the spring. The cutting blade contacts the sheet metal, causing the pinion gear to mesh with the internal gear ring. Pulling the handle moves the slider on the slide rail. Simultaneously, the meshing of the gear and rack causes the gear to drive the gear disc to rotate. The rotating gear disc, through the internal gear ring, drives the pinion gear and the cutting blade on the moving shaft to rotate simultaneously. The rotating cutting blade cuts the sheet metal. The safety cutting component is powered manually, allowing for immediate stopping in case of an accident, preventing injury to the operator from the rotating cutting blade.

[0018] 2. The sheet metal cutting device for the production and processing of this suitcase features a D-shaped hand guard plate. This D-shape shifts the center of gravity of the entire anti-accidental injury protection component upwards. Under normal circumstances, the complete arc of the hand guard plate will automatically rotate downwards under its own weight until it covers the lower surface of the cutting blade. At this point, the cutting blade cannot cut the hand or object below, thus avoiding the tragedy of the cutting blade injuring the hand when no cutting operation is being performed. A hand guard plate is bolted to the outer surface of the hand guard plate, which protects the worker's thumb from accidental injury by the cutting blade when using the sheet metal cutting device.

[0019] 3. The sheet metal cutting device for the production and processing of this suitcase, through the spring, enables the small slider, along with the pinion and the cutting blade, to move upward immediately after cutting. This allows the pinion to immediately disengage from the internal gear ring, avoiding the problem of the cutting blade rotating due to inertia caused by the inertial force of cutting, which could injure the operator.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-3This utility model provides a new technical solution: a sheet material cutting device for trolley case production and processing, including a sheet material cutting table 1, a slide rail frame 3 bolted to the upper surface of the sheet material cutting table 1, and a safety cutting component located on the slide rail frame 3. The safety cutting component is used to ensure the safe cutting of sheet material during trolley case production and processing.

[0026] Furthermore, an anti-injury protection component is located on the sheet metal cutting table 1. The anti-injury protection component is used to prevent workers' hands from being accidentally injured when cutting sheet metal.

[0027] Furthermore, the safety cutting component includes a slider 4, which is slidably connected to the slide rail 3. A first fixing post 5 is welded and fixed to the lower surface of the slider 4. A gear 6 is fixedly sleeved on the outer surface of the first fixing post 5. A rack 7 is bolted to the outer surface of the slide rail 3.

[0028] Furthermore, gear 6 meshes with rack 7, and a fixing frame 11 is welded and fixed to the right surface of slider 4. A second fixing column 8 is fixedly connected between fixing frame 11 and slider 4.

[0029] Furthermore, a gear disk 9 is fixedly sleeved on the outer surface of the second fixed column 8, and the gear disk 9 meshes with the gear 6. An internal gear ring 10 is provided on the right side of the gear disk 9, and a sliding groove 13 is milled on the outer surface of the fixed frame 11.

[0030] Furthermore, a small slider 14 is slidably connected inside the slide groove 13, and a spring 17 is fixedly connected between the bottom wall of the slide groove 13 and the small slider 14. A movable shaft 15 is rotatably connected inside the small slider 14.

[0031] Furthermore, a cutting disc 18 is fixedly installed on the outer surface of the movable rotating shaft 15. Both ends of the movable rotating shaft 15 rotate through the outer surface of the small slider 14. A small gear 16 is fixedly sleeved at one end of the movable rotating shaft 15 that extends into the internal gear ring 10. The small gear 16 is adapted to the internal gear ring 10.

[0032] Furthermore, the anti-accidental injury protection component includes a glove 19, which is rotatably connected to the outer surface of the movable shaft 15 by a bearing. A hand guard 2 is integrally formed at the end of the glove 19 near the cutting blade 18. The hand guard 2 is D-shaped, which makes the center of gravity of the entire anti-accidental injury protection component higher. Under normal circumstances, the complete arc part on the hand guard 2 will automatically rotate downward under its own weight until it covers the lower surface of the cutting blade 18. At this time, the cutting blade 18 cannot cut the hand or object below it, thus avoiding the tragedy of the cutting blade 18 injuring the hand when no cutting operation is being performed. A hand guard plate 12 is bolted to the outer surface of the hand guard 2. The hand guard plate 12 can protect the worker's thumb from being accidentally injured by the cutting blade 18 when using the sheet metal cutting device.

[0033] Furthermore, during use, the position of the sheet metal to be cut on the sheet metal cutting table 1 is aligned with and fixed with the cutting blade 18. Then, the handle 19 is manually pressed down, causing the small slider 14 and the cutting blade 18 to move downwards, compressing the spring 17. The cutting blade 18 contacts the sheet metal, causing the pinion 16 to mesh with the internal gear ring 10. Pulling the handle 19 moves the slider 4 on the slide rail 3. Simultaneously, due to the meshing of the gear 6 and the rack 7, the gear 6 drives the gear disk 9 to rotate. The rotating gear disk 9 drives the pinion 16 and the cutting blade 18 on the moving shaft 15 to rotate simultaneously through the internal gear ring 10. The rotating cutting blade 18 cuts the sheet metal. The safety cutting component is powered manually, which allows for immediate stopping in case of an accident during the entire cutting process, avoiding the problem of the rotating cutting blade 18 accidentally injuring the operator.

[0034] The spring 17 allows the small slider 14, along with the pinion 16 and the cutting disc 18, to move upward immediately after cutting. This enables the pinion 16 to disengage from the inner gear ring 10, preventing the cutting disc 18 from rotating due to inertia caused by the cutting inertia and thus avoiding injury to the operator.

[0035] Working principle: When in use, the position of the thin sheet material to be cut on the sheet cutting table 1 is aligned with the cutting blade 18 and fixed. Then, the handle 19 is manually pressed down, causing the small slider 14 and the cutting blade 18 to move downward, compressing the spring 17. The cutting blade 18 contacts the thin sheet material, causing the pinion 16 to mesh with the internal gear ring 10. Pulling the handle 19 causes the slider 4 to move on the slide rail 3. At the same time, due to the meshing of the gear 6 and the rack 7, the gear 6 drives the gear disk 9 to rotate simultaneously. The rotating gear disk 9 drives the pinion 16 and the cutting blade 18 on the moving shaft 15 to rotate simultaneously through the internal gear ring 10. The rotating cutting blade 18 cuts the thin sheet material.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
