Description

Technical Field

[0001] This utility model relates to the field of metal plate processing, and in particular to a high-efficiency and precise metal cutting equipment. Background Technology

[0002] In the field of metal cutting, there is a type of waterjet cutting equipment that uses special nozzles to generate a high-speed water jet to cut metal parts. During the cutting process, the waterjet cutting equipment typically uses clamping mechanisms such as bench vises and jigs to hold the metal parts in close contact, thus securing them in place.

[0003] When a waterjet cutting device is working, the waterjet comes into contact with the metal part and applies a lateral force to the metal part in the same direction as the waterjet's movement. The bench vise and clamps need to counteract this force. Therefore, when different metal parts are subjected to the same force applied by the bench vise and clamps, the force may be too large, leading to displacement, wear, or even deformation of the metal parts. Conversely, if the force is too small, it may easily cause displacement of the metal parts, thus affecting the accuracy of the metal cutting.

[0004] Therefore, this application provides a highly efficient and precise metal cutting device to meet the requirements. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a high-efficiency and precise metal cutting device to solve the problem of wear and displacement of metal parts of different materials when existing clamps are used to hold metal parts of different materials.

[0006] To solve the problems mentioned above, this utility model is implemented through the following technical solution.

[0007] A high-efficiency and precise metal cutting device, comprising:

[0008] The base has a water jet nozzle that can slide on the top of the base to spray water jets to cut metal parts. An operating table is connected to the side of the base for operating the equipment.

[0009] A recessed platform is formed at the top of the base;

[0010] Multiple support bars are installed on the recessed platform, metal parts are placed on the support bars, and gaps are provided between the multiple support bars to provide cutting space for the water jet nozzle;

[0011] The support strip is made of natural rubber;

[0012] Each of the support bars has a suction port at its top, and the suction port is slidably connected to a suction cup via a spring fixed to the inner wall;

[0013] The diameter of the suction cup is smaller than that of the suction port. The initial position of the suction cup is higher than the suction port, and the lowest point of the movement of the suction cup is at the same height as the support bar.

[0014] Preferably, the number of the support bars is not less than three, and the multiple support bars are arranged in a "hui" shape, and the sizes of the support bars decrease along the inner side.

[0015] Preferably, the top heights of each of the support bars are the same and are all higher than the top of the base. When the metal part is placed on the top of the support bar, it does not contact the base.

[0016] Preferably, the suction ports are respectively arranged at the centers of the four sides of the same suction port, and the depth of the suction port is lower than the height of the support bar.

[0017] Preferably, each of the support bars is hollow and provided with a connecting channel, and each connecting channel communicates with the suction port opened by the same support bar.

[0018] Preferably, the connection part of the adjacent connecting channels on the same support bar is an interface.

[0019] Preferably, the bottom of the connecting channel is inclined, and the lowest point of the connecting channel is the connection part with the suction port, and the highest point is the connection part with the interface.

[0020] Preferably, the lowest point of the connecting channel is higher than the bottom of the suction port.

[0021] Preferably, an exhaust groove is fixedly connected to the bottom of the suction cup. The exhaust groove extends to the inside of the base on the side away from the suction cup and is connected with a one-way valve, and the one-way valve exhausts on the side away from the exhaust groove.

[0022] Preferably, a water collecting groove is opened at the center of the concave table, and the height at the center is higher than that at the corners. A water collecting basin is fixedly connected to the outside of the base, and the water collecting basin is communicated with the water collecting groove.

[0023] The utility model provides a high-efficiency and precise metal part cutting device. Compared with the prior art, it has the following beneficial effects:

[0024] 1. By utilizing the characteristic that the friction coefficient is relatively large when the support bar contacts the metal part with a smooth surface, when the metal part is placed on the top of the support bar, due to the relatively large mass of the metal part and the downward force applied by the cutting device, the friction force between the support bar and the metal part is increased, offsetting the acting force of the water jet on the lateral movement of the metal part during the cutting process, thereby playing a role in fixing the metal part.

[0025] 2. By utilizing the suction force of the suction cup on the metal part and the controllable deformation of the support bar caused by compression, and by using the liquid water and water vapor generated during water jet cutting, water molecules are used to fill the tiny gaps and uneven areas on the surface of the natural rubber, causing the air between the rubber and the contact surface (i.e., the metal part) to be expelled, forming a "vacuum"-like state. This enhances the adhesion between the rubber and the object surface, further increasing the suction force of the support bar on the metal part, thereby achieving a fixing effect on the metal part. This avoids the problems of metal part wear and displacement that may occur when using clamps to hold the metal part, while also improving the accuracy of the cutting equipment.

[0033] The present invention will be further described below with reference to specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0034] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0035] Reference Figure 1 - Figure 5, a highly efficient and precise metal part cutting device, comprising:

[0036] A base 10, on the top of which there is a water jet nozzle 11 that can slide on the top of the base 10 to jet water jets to cut metal parts. A control console 12 is connected to the side of the base 10 for controlling the device;

[0037] A concave platform 20 is formed on the top of the base 10;

[0038] A plurality of support bars 21 are installed on the concave platform 20. The metal parts are placed on the support bars 21, and there are gaps between the plurality of support bars 21 to provide a cutting space for the water jet nozzle 11;

[0039] The material of the support bar 21 is natural rubber;

[0040] At the top of each support bar 21, there is a suction port 22. The suction port 22 is slidably connected with a suction cup 25 through a spring fixed to the inner wall;

[0041] The diameter of the suction cup 25 is smaller than the diameter of the suction port 22. The initial position of the suction cup 25 is higher than the suction port 22, and the lowest point of the movement of the suction cup 25 is at the same height as the support bar 21.

[0042] By controlling the control console 12 to control the movement of the water jet nozzle 11, and then controlling the water jet nozzle 11 to cut the metal parts placed on the top of the support bars 21, to avoid the possible damage caused by clamping the metal parts with fixtures such as bench vises during this process;

[0043] Natural rubber has good anti-wear, anti-cutting, anti-slip and waterproof properties. When the water jet sprayed by the water jet nozzle 11 contacts the support bar 21 during the process of cutting the metal parts, it reduces the damage suffered by the support bar 21.

[0044] The number of the support bars 21 is not less than three, and the plurality of support bars 21 are arranged in a "return" shape, and the sizes of the support bars 21 decrease along the inner side.

[0045] Make the contact surface between the metal part and the support bar 21 perpendicular. When the metal part has a tendency to displace, it improves the friction force given by the support bar 21, improves the fixing effect of the support bar 21, and at the same time increases the gap between each support bar 21 to avoid the water jet contacting the support bar 21 and causing damage to the support bar 21. [[ID=三十二]]

[0046] The top heights of each support bar 21 are the same and are all higher than the top of the base 10. When the metal part is placed on the top of the support bar 21, it does not contact the base 10.

[0047] The metal part first contacts the support bar 21, and then has a fixing effect on the metal part.

[0048] The suction ports 22 are respectively set at the center of the four sides of the same suction port 22, and the depth of the suction port 22 is lower than the height of the support bar 21.

[0049] When the support bar 21 comes into contact with the metal part, the displacement of the metal part itself and the force given by the water jet nozzle 11 will cause the support bar 21 to be compressed downward and deformed. When the water jet nozzle 11 stops spraying briefly, the gas inside the connecting channel 23 is further discharged outward, which increases the internal space of the connecting channel 23 and reduces the pressure, making it lower than the atmospheric pressure outside the support bar 21. As a result, the support bar 21 uses the pressure difference to adhere to the metal part and produce a fixed effect.

[0050] Each support bar 21 is hollow and has a connecting channel 23. Each connecting channel 23 is connected to the suction port 22 of the same support bar 21.

[0051] When the water jet nozzle 11 is working, the liquid water and water vapor generated enter the suction port 22 and reach a certain amount. Then, the liquid water will enter other suction ports 22 of the same support bar 21 through the connecting channel 23, so that the suction force of each suction port 22 is averaged.

[0052] The connection point of adjacent connecting channels 23 on the same support bar 21 is the interface 24.

[0053] This allows the liquid generated when the water jet nozzle 11 is working to also be connected inside the connecting channel 23, uniformly increasing the suction force of the suction port 22.

[0054] The bottom of the connecting channel 23 is inclined, and the lowest point of the connecting channel 23 is the connection point with the suction port 22, and the highest point is the connection point with the interface 24.

[0055] To avoid excessive differences in the proportion of liquid water inside the suction ports 22 at different positions on the same support bar 21, which could lead to excessive differences in suction force between different suction ports 22 and cause the metal parts to tilt.

[0056] The lowest point of channel 23 is higher than the bottom of suction port 22.

[0057] When there is a certain amount of water inside the suction port 22, the gas space inside the suction port 22 is reduced, which improves the sealing of the suction port 22 and thus increases the suction power of the suction port 22.

[0058] The suction cup 25 is fixedly connected to an exhaust groove 26 at its bottom. The exhaust groove 26 extends into the base 10 on the side away from the suction cup 25 and is connected to a one-way valve 27. The one-way valve 27 exhausts air on the side away from the exhaust groove 26.

[0059] The suction cup 25 contacts the metal part and generates suction, which fixes the metal part. At the same time, the suction cup 25 moves downward to the lowest point, causing the metal part to contact the support bar 21, and then compresses the support bar 21, causing the air inside the support bar 21 to be discharged outward through the exhaust groove 26 and the one-way valve 27, so that the air density inside the support bar 21 is less than that outside, and under the action of air pressure, it generates suction on the metal part again.

[0060] A water collection trough 30 is provided at the center of the recessed platform 20, and the height of the center is higher than that of the corners. A water collection basin 31 is fixedly connected to the outside of the base 10, and the water collection basin 31 is connected to the water collection trough 30.

[0061] The water collection tank 30 facilitates the collection of liquid generated during the operation of the water jet nozzle 11 and gathers the liquid into the water collection basin 31 for easy collection by staff.

[0062] During use, the metal part is placed on top of the support strip 21. The support strip 21 contracts downwards due to the weight of the metal part. During this process, the air in the suction port 22 and the connecting channel 23 is expelled, generating suction. This, combined with the friction between the metal part and the top of the support strip 21, confines the metal part to the top of the support strip 21, creating a fixing effect. Under the control of the operating table 12, the water jet nozzle 11 cuts the fixed metal part. During operation, the liquid water and water vapor generated by the water jet nozzle 11 come into contact with the natural rubber support strip 21. Water molecules fill the tiny gaps and uneven areas on the surface of the natural rubber, expelling the air between the rubber and the contact surface, i.e., the metal part, creating a "vacuum"-like state, thereby enhancing the adhesion between the rubber and the object surface. At the same time, the liquid and water vapor enter the suction port 22 and, through the connection of the connecting channel 23, further enhance the suction of the suction port 22, counteracting the lateral movement of the metal part caused by the water jet during the cutting process, thus creating a fixing effect.

[0063] Therefore, although the present invention has been described herein with reference to specific embodiments thereof, freedom of modification, various changes and substitutions are also within the scope of the above disclosure, and it should be understood that in some cases, certain features of the present invention may be adopted without departing from the scope and spirit of the invention and without corresponding use of other features.
