Abstract
Description
Technical Field
[0001] This utility model relates to a protective water tank, and more particularly to a protective water tank for a reciprocating wire EDM machine. Background Technology
[0002] Reciprocating wire EDM machines hold a very special position in the machine tool industry. Especially in recent years, with continuous technological advancements, their excellent machining performance has played an irreplaceable role in fields such as machining, aerospace, weaponry, and mold making. However, while the technology's development has gained industry recognition, increasingly stringent requirements for production sites and environmental protection, along with the continuous development of modern production management, particularly the introduction of 5S and 6S management concepts, have led to the widespread adoption of protective water tanks on machine tool workbenches. These water tanks, including the tank body and the surrounding side doors, are commonly made of acrylic sheets. This is because acrylic sheets are easy to process, relatively lightweight, and their transparency allows workers to easily observe the machining process. Typical installation structures include hinged connection combinations or card-type combination structures.
[0003] It is easy to see that the above two structures are simple in structure and relatively easy to manufacture, but they also have two unavoidable drawbacks: 1. When loading and unloading workpieces, operators have to painstakingly remove and install the side door, which is not only inconvenient to operate, but also, due to the special nature of wire cutting machine processing, the coolant used is very slippery, and the acrylic glass material itself is very smooth. When installing or removing the side door, the operator may be slightly careless and drop it, injuring their foot or breaking it; 2. Since a considerable amount of coolant adheres to the acrylic glass plate after the workpiece has just been processed, placing it on the ground when removing it will inevitably cause damage to the production environment, which is increasingly unable to meet the requirements of production management. Summary of the Invention
[0004] The purpose of this utility model is to address the above-mentioned shortcomings of the existing technology by providing a protective water tank for a reciprocating wire EDM machine. The protective device is a pull-out structure that does not require the machine to be placed on the ground. This not only makes operation convenient and easy, but also eliminates the need to remove the tank from the worktable, thereby improving production efficiency and preventing coolant drips from damaging the cleanliness of the production site, thus meeting management requirements. It also reduces the floor space occupied by the machine tool.
[0005] To achieve the above objectives, this utility model provides a protective water tank for a reciprocating wire EDM machine, comprising a water tank body, a front door, a right side door, a left side door connected to the water tank body, and a rear panel; characterized in that: a vertical plate is fixedly provided at the rear right side of the water tank body, a sliding groove is provided at the front side of the water tank body, a left bent edge is fixedly provided on the left side of the front door, and a front bent edge is fixedly provided on the front side of the right side door; a longitudinal roller is provided in the sliding groove, the roller is connected to a slider above it, the slider is connected to a bearing seat through a hinge shaft, and the bearing seat is fixedly connected to the left bent edge; the right side of the front door is hinged to the front bent edge through a flag-shaped hinge, and the rear end of the right side door is hinged to the vertical plate.
[0006] When the front door, right side door, left side door, and rear panel are in the closed state, coolant splashing can be prevented, achieving protection. When loading or unloading workpieces, the front door can be moved to the right, with rollers and slides facilitating movement and guidance. Simultaneously, the front door can rotate relative to the front bend edge via a flag-shaped hinge, and the right side door can rotate relative to the upright plate. The right side door is folded between the front door and the upright plate, making it easy and convenient to open the front door for operation. Moving the front door in the opposite direction restores the front door and right side door to a right angle. The protective device of this utility model is a pull-type structure that does not require touching the ground. It is not only convenient and easy to operate, but also does not need to be removed from the workbench, which can improve production efficiency and prevent coolant dripping from damaging the cleanliness of the production site, thereby meeting management requirements and reducing the footprint of the machine tool.
[0007] As a further improvement of this utility model, the slider is connected to two horizontal guide wheels, which are placed in the slide groove; the outer diameter of the guide wheels is slightly smaller than the width of the slide groove, so as to prevent the slider from swinging when it moves.
[0008] As a further improvement of this utility model, a shock-absorbing rubber ring is provided inside the right side of the slide groove; it can limit and buffer the movement of the front door.
[0009] As a further improvement of this utility model, the lower ends of the left door and the rear panel are hinged to the water tank body, and magnets are provided in the upright plate and the end of the left door adjacent to the rear panel. Steel plates that cooperate with the magnets are connected to both ends of the rear panel. The left door and the rear panel can be flipped outward to facilitate the installation of large parts. When reset, they can be positioned by the cooperation of the magnets and the steel plates.
[0010] As a further improvement of this utility model, a pad sleeve fitted over the hinge shaft is provided between the slider and the shaft seat; this can prevent the slider from contacting and rubbing against the shaft seat.
[0011] In summary, the protective device of this utility model is a rotary pull structure that does not require touching the ground. It is not only convenient and easy to operate, but also does not need to be removed from the workbench, which can improve production efficiency and prevent coolant dripping from damaging the cleanliness of the production site, thereby meeting management requirements and reducing the footprint of the machine tool.
