[0002] Metal cutting machine tools, also known as industrial machine tools or machine tools, are used to manufacture machinery and occupy a central position in modern manufacturing. Metal cutting involves the use of cutting tools to remove excess material from a metal workpiece to obtain a part that meets the required shape, dimensional accuracy, and surface quality.

[0003] Existing metal cutting machine tools are provided with a bed, an operating table and a cutting machine. The operating table controls the cutting machine to slide along the length direction of the bed, and performs high-precision cutting processing on the metal workpiece fixed on the upper surface of the window to ensure that the size accuracy and shape accuracy of the workpiece meet the design requirements.

[0004] The above-mentioned existing technical solutions have the following defects: when the metal cutting machine tool cuts the workpiece, it will produce flying small metal debris, and the metal waste debris will escape into the air. Workers are likely to inhale the metal debris into their bodies while working, which is harmful to their health. Utility Model Content

[0005] The present application provides a protective dust removal device for metal cutting in order to collect and clean the metal debris generated during the cutting process when a metal workpiece is cut, and to prevent the metal debris from splashing in the air and endangering the health of workers.

[0006] The above technical objectives of this application are achieved through the following technical solutions:

[0007] A protective dust removal device for metal cutting comprises a basic box body, a collecting tray, a movable door, a simple door lock and a square-cone box cover. The basic box body cover is arranged on the upper part of the metal cutting machine tool. The collecting tray is inserted into the metal cutting machine tool and is located below the basic box body and corresponds to the position of the lower box opening of the basic box body. The movable door is movably installed on the basic box body and is locked to the basic box body by the simple door lock. The square-cone box cover is arranged on the upper part of the basic box body, and the top of the square-cone box cover is used to connect a dust suction pipe.

[0008] By adopting the above technical solution, the protective dust removal device is arranged above the metal cutting machine tool. When the metal workpiece is cut, metal debris will be generated. The box wall of the basic box body can prevent the metal debris from flying around. The square cone box cover is arranged above the basic box body and is connected to a dust suction pipe, which can clean the metal debris splashed above the inside of the basic box body. The movable door movably arranged on the basic box body can facilitate the placement of the metal workpiece to be cut on the metal cutting machine tool and the observation of the cutting progress of the metal workpiece. By setting up the basic box body, the metal debris can be collected in the collecting tray, which is convenient for unified treatment of the metal debris, avoiding metal debris splashing in the air, endangering the health of the workers, and improving safety.

[0009] Optionally, the basic box body includes two first strip plates, a second strip plate and a third strip plate, the two first strip plates are arranged in parallel and at intervals, the second strip plates and the third strip plates are arranged in parallel and at intervals between the two first strip plates, and the adjacent side walls of the two first strip plates, the second strip plates and the third strip plates are fixedly connected.

[0010] By adopting the above technical solution, the two first strip plates, the second strip plates and the third strip plates can prevent metal debris generated during the cutting process from flying around the metal cutting machine tool, preventing the metal debris from escaping into the air and endangering the health of workers.

[0011] Optionally, the protective dust removal device also includes a fourth strip plate and a fifth strip plate, the side wall of the fourth strip plate is hinged to the lower part of one of the first strip plates, and the fifth strip plate is fixed to the lower part of another of the first strip plates, and the edge of the collection tray can rest on the surface of the fifth strip plate.

[0012] By adopting the above technical solution, the fourth and fifth strips can be provided to prevent the falling metal debris from flying out of the gap between the collection tray and the lower surface of the base box and falling to the ground when the base box collects the flying metal debris, thereby reducing collection efficiency. The hinged fourth strip facilitates the removal and installation of the collection tray in the metal cutting machine.

[0013] Optionally, the lower surface of the fifth strip plate is bent in a direction away from the fourth strip plate, and the edge of the collecting tray is against the bent surface of the fifth strip plate.

[0014] By adopting the above technical solution, the fifth strip plate with a bent plate surface can cause metal debris to fall into the collection tray, preventing the metal debris from falling on the edge of the collection tray. When the collected metal debris is processed, the collection tray needs to be taken out. If the metal debris is located on the edge of the collection tray during the process of taking out the collection tray, it is easy for the metal debris to fall to the ground or dissipate into the air, thereby reducing the collection efficiency.

[0015] Optionally, the simple door lock includes a lock block, a lock box and a lock rod, the side wall of the lock block is fixed to the movable door, the side wall of the lock box is fixed to the first strip plate surface and is located below the lock block, the lock box is provided with a box opening and the box opening faces the lock block, and a lock hole is provided on the lock block, the lock rod penetrates into the lock box and slides inside the lock box, and one end of the lock rod can be inserted into the lock hole.

[0016] By adopting the above technical solution, the movable door can be locked on the first strip plate by setting a lock block, a lock box and a lock rod, preventing the movable door from moving around and avoiding metal debris from splashing into the air from the square mounting hole, endangering the health of the staff. The lock block, lock box and lock rod are used for locking, which has a simple structure and is convenient and fast.

[0017] Optionally, one end of the locking rod inserted into the locking hole is processed to form an inclined surface, and the inclined surface faces away from the first strip plate.

[0018] By adopting the above technical solution and providing the inclined surface, it is no longer necessary to manually pull the locking rod downward when closing the movable door, thereby improving work efficiency.

[0019] Optionally, the protective dust removal device also includes a square limit plate and a spring, wherein the square limit plate is sleeved on the peripheral wall of the locking rod close to the inclined surface, the square limit plate is adapted to the lock box and is slidably arranged in the lock box, and the spring is sleeved on the peripheral wall of the locking rod and is located between the square limit plate and the bottom of the lock box.

[0020] By adopting the above technical solution, the direction limit plate and the spring are provided to prevent the lock rod from being separated from the lock box. The spring combined with the inclined surface can automatically insert the end of the lock rod into the lock hole when the movable door is closed.

[0021] Optionally, a circular mounting hole is provided on the surface of the first strip plate, and the protective dust removal device further comprises a fan, and the fan is fixedly disposed in the circular mounting hole.

[0022] By adopting the above technical solution, a fan is set to blow the metal debris splashed in the base box until it contacts the surface of the first strip plate.
