Referring to fig. 9 to 10, the water tank may be formed by bending and welding a cross-shaped plate (or a plate 900 to be processed). The bottom of the water tank (i.e. the bottom plate 910) is generally provided with a drain hole 912, and the drain hole 912 can be a round hole, a square hole or a hole with other shapes; it should be appreciated that after the drain hole 912 is machined, it is generally necessary to press the peripheral area of the drain hole 912 so as to sink, so that the drain hole 912 is located at the lowest position of the sink, thereby facilitating drainage. A drain line 911 can be processed at the bottom of the water tank, one end of the drain line 911 is connected with the side wall of the water tank (generally connected to the corner of the water tank), and the other end is communicated with a drain hole 912; it should be understood that when the drain hole 912 is located in the middle region of the water tank, four drain lines 911 are generally machined, and the overall shape is approximately X-shaped, whereas when the drain hole 912 is located in the edge region of the water tank, two drain lines 911 are generally machined, and the overall shape is approximately V-shaped; the drain line 911 is lower than the surrounding area, and water in the water tank actively flows to the drain line 911 and then flows into the drain hole 912 from the drain line 911, so that the drain line 911 is provided to facilitate guiding the flow direction of the water in the water tank, and to facilitate draining of the water, and to keep dry when the water tank is not in use.

The base 100 is a basic carrier for installing and fixing the components of the device, is a conceptual object, and can be any object, such as an object formed by combining one or more components of a metal table, a stone table, a wood table, a bracket, a supporting plate, a supporting frame, the ground and the like, and plays a role in fixing and supporting.

The slide rail structure 200 is provided with structures such as one or more slide grooves or guide rails and combinations thereof that can be slidably coupled to other objects. The lower bending die 300 is provided with a structure corresponding to the slide rail structure 200 and slidably connected to other objects, so as to be slidably connected to the slide rail structure 200. One is that the sliding connection is convenient to disassemble and assemble, so that different bending lower dies 300 can be conveniently replaced according to actual requirements, and water tanks with different types can be processed; and the sliding connection structure plays a certain limiting and positioning role, so that after the bending lower die 300 is installed on the sliding rail structure 200, the first bending groove 310 (or the second bending groove 320, the third bending groove and the like) of the bending lower die 300 can be always aligned with the bending knife 400, and the bending knife 400 can be correctly stretched into the first bending groove 310 when moving downwards, so that the bending knife 400 is prevented from touching other parts of the bending lower die 300 when moving downwards, and is dangerous or damages equipment. It is to be appreciated that the first bending groove 310 (and the second bending groove 320) may be a V-groove, a U-groove, a Z-groove, etc. It should be understood that the slide rail structure 200 includes not only a structure that is slidably connected to other objects, but also a base that carries the structure and other objects, and that acts on the base 100 in a similar manner as a base carrier.

The bending blade 400 is connected to the base 100, typically also in a sliding connection, and is in driving connection with a driving member, and may be driven by the driving member, so that the bending blade 400 moves up and down, thereby being far from or near the first bending slot 310. It should be understood that, the downward moving distance and the downward pressing force of the bending knife 400 can be controlled by a program, for example, when the cross-shaped plate (or the plate to be processed) is bent to form a water tank cube, the degree of bending is required to be large, so that the downward moving distance of the bending knife 400 is large, the degree of penetrating into the first bending groove 310 is deep, and the cross-shaped plate can be folded more to be bent; when the guide line 911 is machined, the bending degree is small (even a certain indentation is formed), so that the distance of the bending knife 400 moving downwards is small, the distance of the bending knife extending into the first bending groove 310 is short, and the bending degree of the plate 900 to be machined is small; therefore, different parts of the water tank can be processed by switching different programs.

The lifting piece 500 is provided, the lifting piece 500 lifts one end of the bending lower die 300 upwards, so that the upper end surface of the bending lower die 300 is in an inclined state, when the plate 900 to be processed is placed on the bending lower die 300, one end of the plate 900 to be processed (generally, a drain hole 912 is formed therein) is located at a higher position, and when the bending blade 400 approaches to the first bending groove 310 of the bending lower die 300, both ends of the bending blade 400 move downwards by the same distance, but one end of the bending blade 400 is deeper into the bending lower die 300 than the other end of the bending blade 400, so that one end of the plate 900 to be processed is pressed into the first bending groove 310 by the bending blade 400, and is pressed deeper (the indentation is deeper or the bending degree is greater), and in the same way, the other end of the plate 900 to be processed is pressed shallower, so that a guide wire 911 is formed, the greater the sinking degree (or the groove depth of the guide wire 911 groove) is deeper, and the guide wire 911 is more convenient for the bacteria to flow into the groove 911 along the direction, and the drain hole 911 is completely emptied, and the bacteria flow in the water can be completely emptied; therefore, the lifting piece 500 is arranged, the guide line 911 does not need to be processed by other equipment, the original water tank bending equipment can be processed, and the processed guide line 911 has good guide effect. It should be understood that after the bending device finishes machining the guide line 911, the lifting member 500 is removed, so that the plate 900 to be machined can be continuously bent, so that the side plate 920 of the water tank on the plate 900 to be machined stands up to form the side wall of the water tank (the side plate 930 of the water tank can be further bent).

Referring to fig. 4 to 8, in some embodiments of the present invention, a positioning member 600 is further included, a lower end of the positioning member 600 is connected to the sliding rail structure 200, and an upper end of the positioning member 600 is used for being inserted into a drain hole 912 of the sink.

Because the drain line 911 generally extends from the drain hole 912 to the sink side wall; the positioning piece 600 is arranged, the positioning piece 600 is connected with the sliding rail structure 200, the center of the positioning piece 600 and the first bending groove 310 on the lower bending die 300 are guaranteed to be positioned on the same straight line (the guide line 911 can be ensured to pass through the center of the drain hole 912), and when the guide line 911 is processed, the drain hole 912 on the plate to be processed is sleeved at the upper end of the positioning piece 600, so that a certain positioning and fixing effect can be achieved, and the positioning of the water tank is facilitated; and, when the drain hole 912 is a round hole and the upper end of the positioning piece 600 is cylindrical, after one guide line 911 is processed, only the plate to be processed needs to be rotated around the positioning piece 600, and the plate to be processed is rotated to a proper angle, so that the next guide line 911 can be processed conveniently and continuously, thereby a plurality of guide lines 911 can be processed conveniently and sequentially, and the production and processing of the sink are facilitated. It should be understood that the side edges of the upper ends of the positioning posts are generally provided with rounded corners or chamfers, so as to facilitate the sheathing of the plate 900 to be processed. It should be understood that the lower end of the positioning member 600 and the sliding rail structure 200 may be fixedly connected, and the positioning may be performed once, and then the water tank may be directly processed, which is simple and convenient; the positioning piece 600 can be detachably or slidably connected, so that the positioning piece 600 can be conveniently disassembled and replaced, the positioning piece 600 with different sizes can be conveniently replaced to be suitable for processing water tanks with different specifications (such as different sizes of the drain holes 912), or the positioning piece 600 can be disassembled when the drain wire 911 is not processed, and the space on the slide rail structure 200 is vacated for other processing operations.

Referring to fig. 4 to 10, in some embodiments of the present invention, a limiting member 700 is further included, one end of the limiting member 700 abuts against the lifting member 500 or the bending lower die 300, and the other end of the limiting member 700 abuts against the positioning member 600.

Referring to fig. 9 and 10, after the drain hole 912 is formed, it is generally necessary to perform punching so that the peripheral region of the drain hole 912 is depressed (a depressed region is formed) so that the drain hole 912 is located at the lowest position of the water tank, thereby facilitating drainage. Therefore, when the drain wire 911 is processed, the other end of the drain wire 911 needs to be communicated with the sinking area, so that water can smoothly flow into the drain hole 912, and preferably, the other end of the drain wire 911 cannot be directly communicated with the drain hole 912 (i.e. the other end of the drain wire 911 needs to be a distance from the drain hole 912 and cannot be directly communicated together), so that the drain wire 911 is prevented from extending into the sinking area, bending deformation of the drain wire 911 has a certain influence on the stamping step, and if the drain wire 911 is arranged in the sinking area, the drain hole 912 of the water tank is not attractive, and the appearance of a product is influenced. The positioning member 600 is spaced apart from the bending die 300 (also referred to as the bending blade 400), and the distance is constant when the press gauge is unchanged. Therefore, by arranging the limiting member 700 such that one end of the limiting member 700 abuts against the lifting member 500 (or directly abuts against the lower bending die 300), and the positioning member 600 abuts against the other end of the limiting member 700, the positioning member 600 is positioned at a correct distance, so that the machined guide line 911 just communicates to the depressed area without excessively extending. It should be understood that the length of the stopper 700 corresponds to the stamped specification, and when the stamped specification is replaced, the processing can be continued by replacing the stopper 700 with the corresponding length.

Referring to fig. 4, 5 and 6, in some embodiments of the present invention, the lower end of the positioning member 600 is slidably connected to the sliding rail structure 200.

The sliding connection plays a certain role in limiting and fixing, so that the positioning piece 600 is firmly connected after being assembled, and cannot easily loosen and separate from the sliding rail structure 200, and particularly cannot easily be dragged by the plate 900 to be processed during processing.

Referring to fig. 4 and 5, in some embodiments of the present invention, at least one of the lifting member 500 and the positioning member 600 is fixedly coupled to the stopper 700.

The limiting piece 700 is fixedly connected with the positioning piece 600 (or the limiting piece 700 and the lifting piece 500, or the limiting piece 700, the lifting piece 500 and the positioning piece 600) in a connecting mode of welding, bonding, hot melting connection, integral forming and the like, so that the processing and the assembly are facilitated.

Referring to fig. 1, 3 and 6, in some embodiments of the present invention, the sliding rail structure 200 includes a limiting protrusion 210, the limiting protrusion 210 is disposed on the base 100, a first sliding groove 330 and a second sliding groove 340 are disposed at a lower end of the lower bending die 300, the first sliding groove 330 and the second sliding groove 340 are both used for sliding connection with the limiting protrusion 210, and a second bending groove 320 is disposed at an upper end of the lower bending die 300.

Referring to fig. 4 to 8, a processing method of a water tank according to an embodiment of the present invention includes the steps of: lifting, namely inserting a lifting piece 500 below one end of the lower bending die 300, so that the lifting piece 500 is positioned between the lower bending die 300 and the sliding rail structure 200, and lifting one end of the lower bending die 300; bending, namely placing the plate 900 to be processed on the lower bending die 300, so that the processing area of the drain hole 912 of the plate 900 to be processed is positioned at a higher position, and moving the bending knife 400 towards the lower bending die 300 to bend the plate 900 to be processed.

In view of the above, in the bending step, one end of the bending lower die 300 is lifted up by the lifting step, so that the upper end surface of the bending lower die 300 is inclined, so that in the bending step, one end of the plate 900 to be processed (generally, the drain hole 912 is formed therein) is located at a higher position, and when the bending blade 400 approaches the first bending groove 310 of the bending lower die 300, both ends of the bending blade 400 move down by the same distance, but one end of the bending blade 400 is deeper into the bending lower die 300 than the other end of the bending blade 400, so that one end of the plate 900 to be processed is pressed into the first bending groove 310 by the bending blade 400, and is pressed deeper (the indentation is deeper or the bending degree is greater), and in the same way, the other end of the plate 900 to be processed is pressed shallower, so that a guide line 911 is formed, which is greater in the sinking degree of the guide line 911 (or the groove depth of the guide groove 911 is deeper), and the guide line 911 is convenient to flow into the drain hole 911, so that the moist and bacteria in the moist environment can be completely and completely dried can be kept. Therefore, through the lifting step, the guide line 911 does not need to be processed by other equipment, the processing can be performed on the original water tank bending equipment, and the guide effect of the processed guide line 911 is good. It should be appreciated that after the bending step, the lifting member 500 is removed, and the bending device may be used to bend the plate 900 to be processed again, so that the side plate 920 of the water tank on the plate 900 to be processed stands up to form a side wall of the water tank (the side plate 930 of the water tank may be further bent). It should be understood that the drain hole 912 of the plate 900 to be processed is generally already cut into the drain hole 912, and in a special case, the drain hole 912 is not yet processed, which is the region to be processed. It should be appreciated that the drain hole 912 machining area of the sheet material 900 to be machined is located at a higher position relative to the area of the sheet material 900 to be machined between the folding knife and the folding lower die. It should be understood that in the bending step, the downward moving distance and the downward pressing force of the bending knife 400 can be controlled by a program, for example, when the cross-shaped plate (or the plate to be processed) is bent to form a water tank cube, the degree of bending is required to be large, so that the downward moving distance of the bending knife 400 is large, the degree of penetrating into the first bending groove 310 is deep, and the cross-shaped plate can be folded to be more bent; in the process of machining the guide line 911, the bending degree is small (even only a certain indentation is required to be formed), so that the distance of the bending knife 400 moving downwards is small, the distance of the bending knife extending into the first bending groove 310 is short, and the bending degree of the plate 900 to be machined is small.

Referring to fig. 4 to 8, in some embodiments of the present invention, a positioning step is further included, in which the positioning member 600 is placed on the slide rail structure 200 such that the positioning member 600 is placed at a side near one end of the lower bending die 300, and in which the drainage hole 912 of the board 900 to be processed is sleeved on the positioning member 600.

Because the drain line 911 generally extends from the drain hole 912 to the sink side wall; the positioning piece 600 is connected with the slide rail structure 200 through the positioning step, so that the center of the positioning piece 600 and the first bending groove 310 on the lower bending die 300 are ensured to be on the same straight line (the guide line 911 can necessarily pass through the center of the drain hole 912), and in the bending step, the drain hole 912 on the plate to be processed is sleeved to the upper end of the positioning piece 600, so that certain positioning and fixing effects can be achieved, and the positioning of the water tank is facilitated; and, when the drain hole 912 is a round hole and the upper end of the positioning piece 600 is cylindrical, after one guide line 911 is processed, only the plate to be processed needs to be rotated around the positioning piece 600, and the plate to be processed is rotated to a proper angle, so that the next guide line 911 can be processed conveniently and continuously, thereby a plurality of guide lines 911 can be processed conveniently and sequentially, and the production and processing of the sink are facilitated. It should be understood that the side edges of the upper ends of the positioning posts are generally provided with rounded corners or chamfers, so as to facilitate the sheathing of the plate 900 to be processed. It should be appreciated that after the lifting step, one end of the lower bending die 300 is higher and the other end is lower, and the positioning member 600 is placed on the side near the higher end of the lower bending die 300. It should be understood that the lower end of the positioning member 600 and the sliding rail structure 200 may be fixedly connected, and the positioning may be performed once, and then the water tank may be directly processed, which is simple and convenient; the positioning piece 600 can be detachably or slidably connected, so that the positioning piece 600 can be conveniently disassembled and replaced, the positioning piece 600 with different sizes can be conveniently replaced to be suitable for processing water tanks with different specifications (such as different sizes of the drain holes 912), or the positioning piece 600 can be disassembled when the drain wire 911 is not processed, and the space on the slide rail structure 200 is vacated for other processing operations. It should be appreciated that one end of the flow guide line 911 is typically connected to four corners of the water tank, so the flow guide line 911 is positioned such that the peaks of the missing four corners of the sheet 900 to be processed are aligned with the first bending groove 310.

Referring to fig. 4 to 10, in some embodiments of the present invention, in the positioning step, the stopper 700 is placed on the sliding rail structure 200 such that one end of the stopper 700 abuts against the lifting member 500 and the positioning member 600 abuts against the other end of the stopper 700.

Referring to fig. 9 and 10, after the drain hole 912 is formed, it is generally necessary to perform punching so that the peripheral region of the drain hole 912 is depressed (a depressed region is formed) so that the drain hole 912 is located at the lowest position of the water tank, thereby facilitating drainage. Therefore, when the drain wire 911 is processed, the other end of the drain wire 911 needs to be communicated with the sinking area, so that water can smoothly flow into the drain hole 912, and preferably, the other end of the drain wire 911 cannot be directly communicated with the drain hole 912 (i.e. the other end of the drain wire 911 needs to be a distance from the drain hole 912 and cannot be directly communicated together), so that the drain wire 911 is prevented from extending into the sinking area, bending deformation of the drain wire 911 has a certain influence on the stamping step, and if the drain wire 911 is arranged in the sinking area, the drain hole 912 of the water tank is not attractive, and the appearance of a product is influenced. The positioning member 600 is spaced apart from the bending die 300 (also referred to as the bending blade 400), and the distance is constant when the press gauge is unchanged. Therefore, by providing the limiting member 700 in the positioning step, one end of the limiting member 700 abuts against the lifting member 500, and the positioning member 600 abuts against the other end of the limiting member 700, so that the positioning member 600 is positioned at a correct distance, and the machined guide line 911 is just communicated to the sinking area without excessively extending. It should be understood that the length of the stopper 700 corresponds to the stamped specification, and when the stamped specification is replaced, the processing can be continued by replacing the stopper 700 with the corresponding length.

Referring to fig. 4 to 10, in some embodiments of the present invention, a punching step is further included in which the periphery of the drain hole 912 on the pre-processed plate material is punched such that the periphery of the drain hole 912 is depressed.

The drain hole 912 is positioned at the lowest position of the water tank by the stamping step, so that the water is conveniently drained.

Referring to fig. 4 to 10, in some embodiments of the present invention, in the bending step, the lifting member 500 is removed, and the junction of the side plate 920 and the bottom plate 910 of the sheet 900 to be processed is placed under the bending blade 400, and the bending blade 400 moves toward the bending lower die 300 to bend the sheet 900 to be processed.

The processing tank is further folded so that the side plates 920 of the tank stand up.

Referring to fig. 4 to 10, in some embodiments of the present invention, in the bending step, the lifting member 500 is removed, and the junction of the side plate 930 and the side plate 920 of the sheet material 900 to be processed is placed under the bending blade 400, and the bending blade 400 moves toward the bending lower die 300 to bend the sheet material 900 to be processed.

The processing water tank is further bent, and the side plate 930 of the water tank is processed.

The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present invention.
