Abstract
Description
Technical Field
[0001] The utility model relates to a numerical control machine tool structure, in particular to a numerical control machine tool cooling structure for roller processing. Background Art
[0002] The machine tool cooling device is an indispensable part of the metal processing process. It achieves the purpose of heat dissipation by forced circulation of coolant, effectively reducing the heat generated during the processing, protecting the accuracy and life of the machine tool, and improving the processing efficiency and quality of the machine tool. The coolant can be water, oil or other special liquids, and the cooling system can be divided into two categories: internal cooling and external cooling. Internal cooling refers to a method of directly spraying the coolant through a nozzle onto the object being processed to dissipate heat. It is suitable for workpieces that need to be processed with higher precision and high speed. External cooling is a method of transporting the coolant through a pipe to the vicinity of the object being processed or directly spraying it on the tool of the machine tool to dissipate heat. It is suitable for processing large and heavy workpieces or workpieces that need to be processed for a long time.
[0003] The machine tool cooling device usually consists of a cooling pump, a coolant storage container, pipes, nozzles and a control system. The cooling pump is responsible for promoting the circulation of the coolant, which is transported to the processing area of the machine tool through the pipe, sprayed onto the tool or workpiece through the nozzle, and returns to the coolant storage container after absorbing heat, forming a closed circulation system. This structural design helps to effectively reduce the heat generated during the processing, protect the accuracy of the machine tool and extend its service life.
[0004] Although the machine tool cooling device can meet the basic cooling needs in design, there are some defects in practical application. For example, only one pipe and nozzle are used for cooling, and the cooling angle and position are relatively single. During the roll processing, the heat will be transferred to other positions, causing thermal damage and thermal deformation to the rest of the roll. Therefore, the single cooling position and narrow cooling range are not ideal for the cooling of the roll. Utility Model Content

An annular groove is arranged on the inner wall of the anti-blocking seat, and the end of the longitudinal connecting rod is located in the annular groove and is rotatably connected to the anti-blocking seat.
[0009] In the cooling structure of the numerically controlled machine tool for roll processing described above, a connecting strip is arranged between adjacent positioning plates. The connecting strip is provided with a long waist hole, and a plurality of connecting holes are arranged on the positioning plate. A positioning bolt connected to the connecting hole is arranged in the long waist hole.

[0020] Embodiment:
[0021] As Figures 1-4 shown, the cooling structure of the numerically controlled machine tool for roll processing includes a first cooling assembly 2 installed at the machine tool processing head 1 and a second cooling assembly 3 surrounding the roll 14. The first cooling assembly 2 includes a mounting plate 21 connected to the machine tool processing head 1. At least one metal shaping hose 22 is provided on the mounting plate 21, and a first nozzle 23 is provided at the water outlet end of the metal shaping hose 22. The second cooling assembly 3 includes an annular sleeve formed by splicing a plurality of positioning plates 31. An arc-shaped pipe 32 is provided in each positioning plate 31. A liquid inlet pipe and a plurality of second nozzles 33 distributed along the arc length direction of the arc-shaped pipe 32 are provided on the arc-shaped pipe 32.
[0022] The utility model cools the machining position of the rolling roll 14 through the first cooling component 2 and the second cooling component 3, improving the cooling range and effect. The first cooling component 2 is installed at the machine tool machining head 1, can move with the machine tool machining head 1, and uses a metal shaping hose 22, which can be bent and twisted at will, so as to conveniently adjust the position of the first nozzle 23, making it accurately and effectively aim at the machining position, the machining tool or other parts of the rolling roll for cooling, removing chips, forming lubrication, and reducing tool wear. The second cooling component 3 is composed of a plurality of positioning plates 31 spliced together. Each positioning plate 31 is provided with an arc-shaped pipe 32 and a second nozzle 33, so that the cooling spray flow rate in each positioning plate 31 can be adjusted separately according to different temperature conditions on the rolling roll 14, and key cooling treatment can be carried out on different positions of the rolling roll 14 from multiple angles, effectively controlling the temperature of the rolling roll 14, reducing thermal deformation and thermal damage, and ensuring machining accuracy.
[0023] Both the first nozzle 23 and the second nozzle 33 include an anti-blocking seat 41 and a nozzle 42. One end of the nozzle 42 extends into the anti-blocking seat 41 and is movably connected with the anti-blocking seat 41 through a connecting spring 43. The other end of the nozzle 42 is provided with a spray hole 44. A connecting frame 45 is arranged in the anti-blocking seat 41. A plug 46 extending into the nozzle 42 is arranged on the connecting frame 45. The plug 46 is in clearance fit with the nozzle 42, and the end size of the plug 46 matches the size of the spray hole 44.
[0024] Anti-blocking seats 41 are designed in both the first nozzle 23 and the second nozzle 33. By using the plug 46 in the anti-blocking seat 41, when the coolant impacts the nozzle 42 through the anti-blocking seat 41, the water pressure pushes the nozzle 42 forward to separate from the plug 46, so that the coolant is sprayed out through the spray hole 44. When the coolant is too little or there is no coolant, the nozzle 42 returns to its original state under the restoring force of the connecting spring 43, so that the plug 46 seals the spray hole 44, thereby preventing external pollutants from entering the first nozzle 23 and the second nozzle 33 through the spray hole 44 and causing blockage.
[0025] A filter screen 51 is further arranged in the anti-blocking seat 41. The connecting frame 45 includes a transverse connecting rod 52 and a longitudinal connecting rod 53. The transverse connecting rod 52 passes through the filter screen 51 and is connected with the plug 46. Cleaning blades 54 located on both sides of the filter screen 51 and in contact with the filter screen 51 are arranged on the transverse connecting rod 52. An annular groove 55 is arranged on the inner wall of the anti-blocking seat 41. The end of the longitudinal connecting rod 53 is located in the annular groove 55 and is rotatably connected with the anti-blocking seat 41. The arranged filter screen 51 filters impurities in the coolant. When the filter screen 51 needs to be cleaned, as long as the anti-blocking seat 41 is removed and the connecting frame 45 is rotated, the cleaning blades 54 can drive to clean the filter screen 51, without taking out the filter screen 51 for cleaning, and the operation is convenient and time-saving.
[0026] A connecting strip 34 is provided between adjacent positioning plates 31. A long slot 35 is provided on the connecting strip 34, and a number of connecting holes 36 are provided on the positioning plates 31. A positioning bolt 37 connected to the connecting holes 36 is provided in the long slot 35. The adjacent positioning plates 31 are connected by the connecting strip 34, and the distance between the adjacent positioning plates 31 can be adjusted through the connecting strip 34, so as to be applicable to the cooling treatment of rolling rolls 14 with different diameters.
[0027] The cooling structure of the numerical control machine tool for roll processing further includes a machine tool base 11. A chute 12 is provided on the machine tool base 11, and a number of parallel distributed slide rails 13 are provided on the chute 12. A slide plate 38 that is slidably connected with the slide rails 13 in a matching manner is provided on the positioning plate 31 at the bottom. The annular sleeve can move on the slide rails 13 through the slide plate 38, and the position of the annular sleeve can be adjusted, so as to adjust the cooling position of the rolling roll 14, and the use is flexible.
