Description

Technical Field

[0001] The invention relates to the technical field of metal product cutting, in particular to a hardware product cutting device. Background Art

[0002] In the field of metal processing, precise cutting of metal pipes is a common and critical process operation. The traditional method of cutting metal pipes is usually to fix the two ends of the metal pipe and then use a saw blade to cut the middle part. However, there are some technical problems that need to be solved in this process.

[0003] First, in the initial stage of cutting, the cut of the metal tube is gradually formed and slowly becomes larger, but due to the lack of an effective support structure at the cut, the pressure exerted by the saw blade easily causes the metal tube to deviate. This deviation not only affects the precision and quality of cutting, but may also cause damage to the metal tube, increase the scrap rate, and reduce production efficiency. Secondly, as the number of times the saw blade is used increases, wear and tear will inevitably occur. The surface of the worn saw blade is no longer sharp, and the friction between it and the metal tube increases significantly. This not only increases the energy consumption during the cutting process, but also makes it easy for the cut of the metal tube to become blunt, further reducing the cutting quality, which may increase the difficulty of subsequent processing procedures and affect the overall performance and service life of the product. On the other hand, the increased friction between the saw blade and the metal tube will further cause the metal tube to deviate, so that the cut of the metal tube is no longer flat and smooth. In order to improve the precision, quality and efficiency of metal tube cutting, solve the problem of metal tube offset during cutting and the problem of blunt cut caused by saw blade wear, it is necessary to improve and innovate the existing cutting technology and equipment.

In the process of the saw blade cutting the metal pipe, when the saw blade cutting generates an extrusion force so that the metal pipe is about to deviate from the inside of the clamping assembly, the clamping assembly can block the fixed part of the metal pipe, and the supporting assembly is used to support the surrounding part of the metal pipe. When the supporting assembly is squeezed by the metal pipe, the supporting assembly can spray water near the incision of the metal pipe for lubrication and cooling.

In the hardware cutting equipment, two clamping assemblies are provided to fix the metal pipe to be cut, and two driving assemblies are used to drive the steel pipe to be cut to approach the saw blade. In the process of the saw blade cutting the metal pipe, when the extrusion force generated by the saw blade cutting causes the metal pipe to be offset from the inside of the clamping assembly, the saw blade gradually cuts the metal pipe in the process of the two driving assemblies driving the metal pipe to move toward the saw blade. The saw blade generates a large extrusion force on the metal pipe, and the contact part between the metal pipe and the saw blade is blocked by the saw blade.

When the support assembly is squeezed by the metal pipe, the support assembly can spray water near the incision of the metal pipe for lubrication and cooling. Specifically, when the metal pipe is cut and squeezed by the saw blade, the outer wall of the metal pipe pushes the buffer arm to slide into the liquid storage chamber. At the same time, the second spring is compressed by the support arm, thereby preventing the metal pipe from deviating. At the same time, the water contained in the liquid storage chamber is compressed by the support arm, and then the compressed water passes through the compression hole into the nozzle, and finally the water is sprayed from the nozzle to the vicinity of the incision of the metal pipe.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Example

[0030] See also Figure 1-Figure 6 As shown, the purpose of this embodiment is to provide a hardware cutting device, including a workbench 12 arranged on the top of a cabinet 11, a saw blade 13 is arranged at the center of the top of the workbench 12, a pair of driving components 20 are arranged on the top of a pair of side walls away from each other of the workbench 12, a bracket 24 is fixedly connected between the two driving components 20, and a working group is arranged at the bottom of the bracket 24;

[0031] Among them, the working group includes a pair of clamping assemblies 30 and a pair of supporting assemblies 40 fixedly connected to the bottom of the bracket 24, the two supporting assemblies 40 are located between the two clamping assemblies 30, the two clamping assemblies 30 are used to fix the metal pipe to be cut, and the two driving assemblies 20 are used to drive the steel pipe to be cut to approach the saw blade 13. In the process of the saw blade 13 cutting the metal pipe, when the saw blade 13 generates an extrusion force so that the metal pipe is about to deviate from the inside of the clamping assembly 30, the clamping assembly 30 can block the fixed part of the metal pipe, and the supporting assembly 40 is used to support the surrounding part of the metal pipe. When the supporting assembly 40 is squeezed by the metal pipe, the supporting assembly 40 can spray water near the incision of the metal pipe for lubrication and cooling.

[0032] Working principle: First, place the metal pipe to be cut between the two clamping components 30, and then turn on the power of the driving component 20. The driving component 20 drives the metal pipe to move toward the saw blade 13. As the saw blade 13 cuts the metal pipe, the saw blade 13 will generate a large squeezing force on the incision of the metal pipe, thereby preventing the incision of the metal pipe from moving forward along with the part fixed by the clamping component 30. The forces in different directions applied by the clamping component 30 and the saw blade 13 to the two ends of the metal pipe will cause the metal pipe to tend to deviate from the clamping component 30. The part of the metal pipe fixed by the clamping component 30 is blocked by the inside of the clamping component 30, and the part near the incision of the metal pipe is blocked by the support component 40. After the support component 40 is squeezed by the metal pipe, the support component 40 sprays water mist around the incision of the metal pipe to cool and lubricate the incision of the metal pipe.

[0033] like Figure 4 As shown, the specific structure of the clamping assembly 30 is disclosed. The clamping assembly 30 includes a pair of clamping arms 31 symmetrically arranged in the vertical direction. A plurality of guide rods 32 are arranged on the inner top wall of the clamping arm 31 located at the upper side. The plurality of guide rods 32 are slidably connected to the clamping arm 31 located at the lower side. A plurality of guide rods 32 are provided with limit caps at the bottom. A plurality of first springs 33 are sleeved on the periphery of the plurality of guide rods 32. The plurality of first springs 33 are arranged between the bottom of the clamping arm 31 located at the lower side and the limit cap.

[0034] Furthermore, a buffer pad is provided on the side where the two clamping arms 31 are close to each other; when the two driving assemblies 20 drive the metal pipe to move toward the saw blade 13, the saw blade 13 gradually cuts the metal pipe, and the saw blade 13 exerts a large extrusion force on the metal pipe. The contact part between the metal pipe and the saw blade 13 is blocked by the saw blade 13, and the part of the metal pipe fixed by the two clamping arms 31 moves forward with the driving assembly 20, so the metal pipe will be offset from the clamping arms 31. The metal pipe between the two clamping arms 31 will be limited by the guide rods 32 on both sides, and the part near the cut of the metal pipe will be blocked by the support assembly 40, so as to prevent the metal pipe from falling from between the two clamping arms 31 after being cut.

[0035] Figure 5 and Figure 6 The working state of the support assembly 40 from different viewing angles is shown. The specific structure of the support assembly 40 is disclosed below. The support assembly 40 includes a support arm 41. The support arm 41 is provided with a liquid storage cavity 42 on a side close to the steel pipe to be cut. A buffer arm 43 is slidably connected in the liquid storage cavity 42. The outer wall of the buffer arm 43 is in contact with the inner wall of the liquid storage cavity 42. A plurality of second springs 44 are fixedly connected between the buffer arm 43 and the bottom of the liquid storage cavity 42.

[0036] Furthermore, a plurality of compression holes 45 are provided on the side wall of the liquid storage chamber 42 near another support assembly 40, and the plurality of compression holes 45 are connected to a nozzle 46 on the outside of the liquid storage chamber 42; when the metal tube is cut and squeezed by the saw blade 13, the outer wall of the metal tube pushes the buffer arm 43 to slide into the liquid storage chamber 42, and at the same time, the second spring 44 is compressed by the support arm 41, thereby preventing the metal tube from shifting, and at the same time, the water contained in the liquid storage chamber 42 is compressed by the support arm 41, and then the compressed water passes through the compression hole 45 into the nozzle 46, and finally the water is sprayed by the nozzle 46 to the vicinity of the cut of the metal tube.

[0037] In order to drive the metal pipe to be cut, which is fixed at both ends, to approach the rotating saw blade 13;

[0038] like Figure 2 As shown, the driving assembly 20 includes a slide rail 21 fixedly connected to the top of the workbench 12, a slide seat 22 is slidably connected to the bottom of the slide rail 21, and a plurality of pulleys 23 are rotatably connected inside the slide seat 22, and the pulleys 23 are driven by a servo motor.

[0039] The improvement is that after the power is turned on, the servo motor drives the pulley 23 coaxially connected to its own output shaft to rotate, and under the action of the friction between the pulley 23 and the slide rail 21, the two slides 22 drive the clamping assembly 30 at the bottom to move toward the saw blade 13 through the bracket 24.

[0040] In order to meet the cutting needs of metal pipes of different diameters;

[0041] Figure 3 The connection status between the clamping assembly 30 and the supporting assembly 40 is shown. A pair of connecting rods are provided between the two clamping arms 31 and the supporting arms 41 from top to bottom. The upper clamping arms 31 and the supporting arms 41 are fixedly connected to the upper connecting rods, the lower connecting rods are fixedly connected to the support arms 41, and the lower connecting rods are slidably connected to the lower clamping arms 31.

[0042] The improvement lies in that when installing the metal pipe to be cut, the lower clamp arm 31 is pulled to slide downward along the guide rod 32. At the same time, the first spring 33 is compressed, and the metal pipe is inserted between the two clamp arms 31 of the two clamping assemblies 30. The pulling force on the lower clamp arm 31 is removed, and the clamp arm 31 is reset under the action of the restoring force of the first spring 33, thereby fixing the metal pipe between the upper and lower pairs of clamp arms 31. During the downward sliding process of the lower clamp arm 31, the clamp arm 31 remains stable under the limit of the connecting rod located below.

[0043] In summary, the working principle of the present solution is as follows: first, the lower clamp arm 31 is pulled to slide downward along the guide rod 32, and at the same time, the first spring 33 is compressed, so that the metal tube is inserted between the two clamp arms 31 of the two clamping assemblies 30, and the pulling force on the lower clamp arm 31 is removed, and the clamp arm 31 is reset under the action of the restoring force of the first spring 33, thereby fixing the metal tube between the upper and lower clamp arms 31;

[0044] Then, the power of the driving assembly 20 is turned on, and the servo motor drives the pulley 23 coaxially connected to its own output shaft to rotate. Under the action of the friction between the pulley 23 and the slide rail 21, the two slides 22 drive the clamping assembly 30 at the bottom to move toward the saw blade 13 through the bracket 24;

[0045] In the process of the two slides 22 driving the metal tube to move toward the saw blade 13, the saw blade 13 gradually cuts the metal tube, and the saw blade 13 exerts a large extrusion force on the metal tube. The contact part of the metal tube with the saw blade 13 is blocked by the saw blade 13, and the part of the metal tube fixed by the two clamping arms 31 moves forward with the bracket 24, so the metal tube will be offset from the clamping arms 31. The metal tube between the two clamping arms 31 will be limited by the guide rods 32 on both sides, and the part near the cut of the metal tube will be blocked by the support arm 41, so as to prevent the metal tube from falling from between the two clamping arms 31 after being cut;

[0046] When the metal tube is cut and squeezed by the saw blade 13, the outer wall of the metal tube pushes the buffer arm 43 to slide into the liquid storage chamber 42. At the same time, the second spring 44 is compressed by the support arm 41, thereby preventing the metal tube from deflecting. At the same time, the water contained in the liquid storage chamber 42 is compressed by the support arm 41, and then the compressed water passes through the compression hole 45 into the nozzle 46. Finally, the water is sprayed by the nozzle 46 to the vicinity of the cut of the metal tube.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention.
