Description

Technical Field

[0001] The utility model belongs to the technical field of metal product production, and specifically relates to a CNC bending device for metal product production. Background Art

[0002] The metal products industry includes structural metal products manufacturing, metal tool manufacturing, container and metal packaging container manufacturing, stainless steel and similar daily metal products manufacturing, etc. With the progress of society and the development of science and technology, metal products are increasingly used in industry, agriculture and various fields of people's lives, creating more and more value for society.

[0003] In the production process of metal products, CNC bending equipment is a very important processing equipment. It can bend metal sheets according to predetermined angles and shapes to meet the production needs of various workpieces.

[0004] However, there are often some problems in traditional CNC bending equipment. During the bending process, impurities such as metal chips and lubricating oil are easily generated on the surface where the workpiece contacts the bending tool (such as a V-shaped bending knife). These impurities will affect the quality of the bending, causing scratches and wear on the workpiece surface, reducing the quality of the product. In addition, the presence of impurities will increase the friction between the workpiece and the tool, affecting the accuracy and efficiency of the bending.

[0005] To this end, we proposed a CNC bending equipment for metal product production, which can remove impurities during the bending process. The equipment should not only be able to effectively remove impurities on the surface of the workpiece to ensure the quality and efficiency of the workpiece bending. At the same time, after the bending is completed, the workpiece can be easily removed to save operation time and manpower. Utility Model Content

[0006] The purpose of this utility model is to provide a CNC bending device for metal product production, which can remove impurities during the bending process. The device should not only be able to effectively remove impurities on the surface of the workpiece to ensure the quality and efficiency of the workpiece bending. At the same time, after the bending is completed, the workpiece can be easily removed to save operation time and manpower.

[0007] The technical solutions adopted in this utility are as follows:

[0008] A CNC bending device for metal product production comprises a bracket, a bending seat and a telescopic assembly are arranged on the bracket, a mounting plate is arranged on the telescopic assembly, and a V-shaped bending knife is installed at the bottom of the mounting plate;

[0009] The bending seat is a middle shell structure, a V-shaped cavity is formed on the bending seat, bearing grooves are formed on two inclined side walls of the V-shaped cavity, and a first through hole is formed at the bottom of the V-shaped cavity;

[0010] Two partition plates are arranged inside the bending seat, and the two partition plates divide the bending seat into a first cutting fluid chamber, a waste liquid bearing chamber and a second cutting fluid chamber. A third through hole is opened at the four corners of the bending seat, and a hollow rod is arranged inside the third through hole. A hollow lifting plate connected to the hollow cavity is arranged on the hollow rod, and the hollow lifting plate matches the bearing groove, and a plurality of second through holes are opened on the hollow lifting plate. A sliding sealing plate is arranged at the bottom of the hollow rod, and one end of the sliding sealing plate is slidably connected to one of the partition plates, and the other end of the sliding sealing plate is slidably connected to the inner wall of the bending seat. A fourth through hole is opened at the connection between the sliding sealing plate and the hollow rod, and a spring is sleeved on the hollow rod, and the spring is located between the sliding sealing plate and the inner wall of the top of the bending seat.

[0011] Furthermore, the length, width and thickness of the hollow lifting plate are the same as the length, width and thickness of the bearing slot.

[0012] Furthermore, an exhaust hole is provided at the top of the hollow rod.

[0013] Furthermore, the first cutting fluid chamber and the second cutting fluid chamber are both provided with water inlet pipes, and the bottom of the waste liquid bearing chamber is provided with a drain pipe.

[0014] Furthermore, the telescopic assembly includes a hydraulic cylinder disposed on the bracket, and a telescopic end of the hydraulic cylinder is connected to the mounting plate.

[0015] Furthermore, a rubber layer is provided on the sliding sealing plate.

[0016] The technical effects achieved by this utility model are:

[0017] The V-shaped blade is then moved downwards to contact the workpiece, and the workpiece is then moved into the V-shaped cavity for bending. When the V-shaped blade moves downwards, the mounting plate squeezes the hollow rod to move it inside the third through hole. The hollow rod then drives the sliding sealing plate to move on the partition plate and the inner wall of the bending seat, thereby squeezing the cutting fluid inside the first cutting fluid cavity and the second cutting fluid cavity. Due to the effect of pressure, the cutting fluid enters the hollow rod through the fourth through hole, and then enters the hollow cavity of the hollow lifting plate. The cutting fluid then flows out through the second through hole, thereby removing impurities on the surface in contact with the V-shaped blade. After cleaning, the cutting fluid with impurities flows into the waste liquid bearing cavity through the first through hole for discharge. After the bending is completed, the hollow rod is restored to its original position by the elastic force of the spring, thereby driving the hollow lifting plate to move up, so that it is very convenient for people to take it out, thereby saving time and effort. The device can remove impurities on the surface in contact with the V-shaped bending knife during bending, which can not only achieve lubrication to reduce friction and prevent wear of the workpiece when it moves, but also remove impurities to prevent scratches and damage to the workpiece, thereby improving the quality of the workpiece. It can also be easily removed by people, saving time and effort. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is specifically described below in conjunction with the embodiments. It should be understood that the following text is only used to describe one or several specific implementations of the present invention, and does not strictly limit the scope of protection specifically requested by the present invention.

[0026] like Figure 1-5 As shown, the technical solution adopted by the utility model is specifically as follows: a CNC bending device for metal product production, comprising a bracket 1, a bending seat 2 and a telescopic component are arranged on the bracket 1, a mounting plate 3 is arranged on the telescopic component, and a V-shaped bending knife 4 is installed at the bottom of the mounting plate;

[0027] The bending seat 2 is a middle shell structure, a V-shaped cavity 5 is formed on the bending seat 2, bearing grooves 6 are formed on two inclined side walls of the V-shaped cavity 5, and a first through hole 7 is formed at the bottom of the V-shaped cavity 5;

[0028] Two partition plates 8 are arranged inside the bending seat 2, and the two partition plates 8 divide the bending seat 2 into a first cutting fluid chamber 9, a waste liquid bearing chamber 10 and a second cutting fluid chamber 11. A third through hole is opened at the four corners of the bending seat 2, and a hollow rod 12 is arranged inside the third through hole. A hollow lifting plate 13 connected to the hollow cavity is arranged on the hollow rod 12, and the hollow lifting plate 13 matches the bearing groove 6, and a plurality of second through holes are opened on the hollow lifting plate 13. A sliding sealing plate 14 is arranged at the bottom of the hollow rod 12, and one end of the sliding sealing plate 14 is slidably connected to one of the partition plates 8, and the other end of the sliding sealing plate 14 is slidably connected to the inner wall of the bending seat 2. A fourth through hole 15 is opened at the connection between the sliding sealing plate 14 and the hollow rod 12, and a spring 16 is sleeved on the hollow rod 12, and the spring 16 is located between the sliding sealing plate 14 and the inner wall of the top of the bending seat 2.

[0029] Its working principle is as follows: first, the workpiece to be bent is placed on the bending seat 2, and then the telescopic assembly drives the V-shaped bending knife 4 to move downward, so as to contact the workpiece, so that the workpiece enters the V-shaped cavity 5 for bending. When the V-shaped bending knife 4 moves downward, the mounting plate 3 squeezes the hollow rod 12 to make it move inside the third through hole, and then the hollow rod 12 drives the sliding sealing plate 14 to move on the partition plate 8 and the inner wall of the bending seat 2, thereby squeezing the cutting fluid inside the first cutting fluid cavity 9 and the second cutting fluid cavity 11. Because the pressure The cutting fluid enters the hollow rod 12 through the fourth through hole 15, then enters the hollow cavity of the hollow lifting plate 13, and then flows out through the second through hole, thereby removing impurities on the surface in contact with the V-shaped bending knife 4. After cleaning, the cutting fluid with impurities flows into the waste liquid bearing cavity 10 through the first through hole 7 for discharge. After the bending is completed, the hollow rod 12 is restored to its original position by the elastic force of the spring 16, thereby driving the hollow lifting plate 13 to move up, so that it is very convenient for people to take it out, achieving the effect of saving time and effort. The device can remove impurities on the surface in contact with the V-shaped bending knife 4 when bending, which can not only achieve lubrication to reduce friction and prevent wear of the workpiece when moving, but also remove impurities to prevent scratches and damage to the workpiece, thereby improving the quality of the workpiece, and it is also very convenient for people to take it out, achieving the effect of saving time and effort.

[0030] There are multiple groups of first through holes 7 , and such a configuration enables the cutting fluid mixed with impurities to quickly pass through the first through holes 7 into the waste liquid bearing cavity 10 .

[0031] The working state of the utility model is: first, the V-shaped bending knife 4 moves downward, and the mounting plate 3 squeezes the hollow rod 12. During the squeezing, the hollow lifting plate 13 overlaps with the bearing groove 6. After the overlap, the cutting fluid enters the hollow lifting plate 13 through the fourth through hole 15 and the hollow rod 12 due to the effect of pressure, and then flows out through the second through hole, thereby cleaning the surface of the hollow lifting plate 13.

[0032] At the same time, the length, width and thickness of the hollow lifting plate 13 are the same as those of the bearing groove 6. This arrangement enables the hollow lifting plate 13 to form a complete V-shaped cavity after entering the bearing groove 6, thereby not affecting the bending.

[0033] An exhaust hole 17 is provided at the top of the hollow rod 12, and the cutting fluid can enter the interior of the hollow rod 12 through the exhaust hole 17, thereby achieving pressure balance and allowing the cutting fluid to move due to pressure.

[0034] The first cutting fluid chamber 9 and the second cutting fluid chamber 11 are both provided with water inlet pipes, through which the cutting fluid enters the first cutting fluid chamber 9 and the second cutting fluid chamber 11 , and a drain pipe is provided at the bottom of the waste liquid bearing chamber 10, through which the waste liquid is discharged.

[0035] Water pumps are provided on both the water inlet pipe and the water outlet pipe, and the cutting fluid is allowed to enter or be discharged through the water pumps. This belongs to the prior art and will not be described in detail here.

[0036] A rubber layer is provided on the sliding sealing plate 14, and the effect of pressure is enhanced by the rubber layer.

[0037] The telescopic assembly includes a hydraulic cylinder 18 disposed on the bracket 1 . The telescopic end of the hydraulic cylinder 18 is connected to the mounting plate 3 . The mounting plate 3 is driven to move by the hydraulic cylinder 18 .

[0038] The working principle of the utility model is as follows: firstly, the workpiece to be bent is placed on the bending seat 2, and then the V-shaped bending knife 4 is driven downward by the telescopic assembly to contact the workpiece, so that the workpiece enters the V-shaped cavity 5 for bending. When the V-shaped bending knife 4 moves downward, the mounting plate 3 squeezes the hollow rod 12 to make it move inside the third through hole, and then the hollow rod 12 drives the sliding sealing plate 14 to move on the partition plate 8 and the inner wall of the bending seat 2, thereby squeezing the cutting fluid inside the first cutting fluid cavity 9 and the second cutting fluid cavity 11. Due to the effect of pressure, the cutting fluid enters the hollow rod 12 through the fourth through hole 15, then enters the hollow cavity of the hollow lifting plate 13, and then flows out through the second through hole, thereby removing impurities on the surface in contact with the V-shaped bending knife 4. After cleaning, the cutting fluid with impurities flows into the waste liquid bearing cavity 10 through the first through hole 7 for discharge. After the bending is completed, the hollow rod 12 is restored to its original position by the elastic force of the spring 16, thereby driving the hollow lifting plate 13 to move up, so that it is very convenient for people to take it out, achieving the effect of saving time and effort. The device can remove impurities on the surface in contact with the V-shaped bending knife 4 when bending, which can not only achieve lubrication to reduce friction and prevent wear of the workpiece when moving, but also remove impurities to prevent scratches and damage to the workpiece, improve the quality of the workpiece, and make it very convenient for people to take it out, achieving the effect of saving time and effort.

It should be noted that, for ordinary technicians in the field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention.
