Description

Technical Field

[0001] The present invention relates to the technical field of plate processing, and in particular to a plate cutting and processing device. Background Art

[0002] Sheet metal cutting refers to the process of cutting, splitting or shaping raw sheets (such as metal, wood, plastic, composite materials, etc.) according to design requirements by mechanical or manual means.

[0003] During sheet metal processing, the cutting process generates a large amount of waste chips. Traditional cutting equipment usually lacks an effective waste chip collection structure, which causes the waste chips to fly, pollute the working environment, and even affect the normal operation of the equipment. In addition, the high-speed rotation and friction of the cutter head during cutting generate high temperatures. If the cooling is not sufficient, it is easy to cause the cutter head to wear more, affecting the processing accuracy and tool life. In the existing technology, external spray cooling is generally used, but the cooling effect is limited and may aggravate the splashing of waste chips. Therefore, there is an urgent need for a cutting processing device that can efficiently collect waste chips and optimize the cooling of the tool head. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0018] The present invention will be further described below with reference to the embodiments. Embodiment 1:

[0019] Reference Figure 1-6 , which is the first embodiment of the present invention, is a plate cutting and processing device, comprising two machine bases 1 arranged in parallel, with a plurality of equally spaced and parallel conveyor rollers 11 rotatably mounted between the two machine bases 1, a cutting assembly comprising two cutting motors 41 that can slide horizontally and vertically above the plurality of conveyor rollers 11, a cutting head 42 being detachably mounted on the output ends of the two cutting motors 41, a mounting seat 43 being fixedly mounted on the bottoms of the two cutting motors 41, and a protective cover 44 being disposed directly below the two mounting seats 43, a rubber or silicone sealing strip being added to the bottom of the protective cover 44 to ensure that it fits the plate, and the protective cover 44 can prevent waste chips generated by cutting from scattering; A spring 45 is installed between the top of the protective cover 44 and the lower bottom of the corresponding mounting seat 43. The design purpose of the spring 45 is to ensure that when the cutting head 42 needs to perform cutting operations of different depths on different types of plates, the protective cover 44 can always fit the upper surface of the plate. The cutting head 42 is arranged in the protective cover 44, and an annular nozzle 46 is arranged around the cutting head 42. The output port of the annular nozzle 46 is arranged on the inner ring wall and is tilted downward, so that the part where the cutting head 42 is in direct contact with the plate can be directly flushed. The annular nozzle 46 is fixedly installed in the protective cover 44, and the input end is connected to the water inlet pipe 47, and the water inlet pipe 47 is connected to the output port of the external water pump. Example 2:

[0020] Reference Figure 1-4 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: both ends of the plurality of conveying rollers 11 are fixedly connected with rotating shafts, and the plurality of rotating shafts are rotatably installed in the corresponding machine bases 1. A plurality of driven sprockets are provided in one of the machine bases 1, and the plurality of driven sprockets are fixedly installed on the corresponding rotating shafts, and a first reduction motor 12 is vertically fixedly installed on the outer wall of the machine base 1. The output shaft of the first reduction motor 12 is connected with a driving sprocket. The driving sprocket and the plurality of driven sprockets are jointly covered with a chain. The transmission wrap angle of the chain is greater than 120°, which can disperse the tension through friction and meshing teeth, reduce the tension difference between the loose side and the tight side of the chain, reduce vibration and noise, and make the force on the chain more uniform, thereby avoiding local wear (such as only a few teeth are continuously stressed), and extending the service life of the chain and sprocket. A lateral movement assembly is provided above the two machine bases 1, and the lateral movement assembly includes two first fixed bases 21 fixedly mounted on the top of one of the machine bases 1, and also includes two second fixed bases 24 mounted on the top of the other machine base 1. A lead screw 22 is rotatably mounted between the two first fixed bases 21, and a second reduction motor 23 with an output shaft fixedly connected to the lead screw 22 is vertically fixedly mounted on the outer wall of one of the first fixed bases 21. A guide rod 25 is fixedly connected between the two second fixed bases 24. A nut seat 26 is threadedly sleeved on the outer shaft wall of the lead screw 22, and a guide sleeve 27 is slidably sleeved on the outer rod wall of the guide rod 25. A moving platform 28 is fixedly connected between the nut seat 26 and the guide sleeve 27, and a through hole is opened at the top and bottom of the moving platform 28; Two third fixing seats 31 are vertically fixedly connected to the top of the movable platform 28. A third reduction motor 32 is vertically fixedly mounted on the outer wall of one of the third fixing seats 31. A double-ended screw 33 rotatably mounted between the two third fixing seats 31 is fixedly connected to the output shaft of the third reduction motor 32. Threaded rings 34 are threadedly mounted on both ends of the double-ended screw 33. The bottoms of the two threaded rings 34 are vertically fixed with lifting assemblies 35. Both lifting assemblies 35 pass through the through-holes and extend to the bottom of the moving platform 28. The bottoms of the two lifting assemblies 35 are installed with cutting motors 41. The lifting assemblies 35 include a lifting rod, a lifting cylinder and a fastening screw. The top of the lifting rod passes through the through-hole and is vertically fixed with the two threaded rings 34, and the bottom of the lifting rod is inserted into the corresponding lifting cylinder. The bottoms of the two lifting cylinders are fixed with the corresponding cutting motors 41. The fastening screws are threadedly installed at the upper tube mouth of the lifting cylinder and conflict with the corresponding lifting rods. Scale lines are set on the side wall of the lifting cylinder. The overall height of the cutting assembly can be adjusted through the lifting assembly 35, which is convenient for effective cutting of plates of different thicknesses.

[0021] The remaining structures are the same as those of Example 1. Example 3:

[0022] Reference Figure 1-2 5-6 is the third embodiment of the present invention, which is different from the second embodiment in that: Telescopic cylinders 51 are vertically fixedly installed on the outer walls of the two machine bases 1. Telescopic rods 52 are connected to the output shafts of the two telescopic cylinders 51. Extrusion plates 53 are vertically fixedly installed on the opposite ends of the two telescopic rods 52. The two extrusion plates 53 are respectively arranged on the inner walls of the two machine bases 1 and above the several conveying rollers 11. Pressure sensors are installed at the connection between the output shafts of the two telescopic cylinders 51 and the corresponding telescopic rods 52. The two pressure sensors are electrically connected to an external controller. The controller controls the start and stop of the two telescopic cylinders 51 through pressure feedback from the two pressure sensors to prevent the telescopic cylinders 51 from applying too much thrust, which may cause the plate to be squeezed and damaged. A receiving hopper 61 is fixedly installed between the two machine bases 1. The receiving hopper 61 is set below the several conveying rollers 11. A filter screen 62 is detachably installed at the upper cavity opening of the receiving hopper 61. Two handles 63 are vertically fixedly installed on the top of the filter screen 62.

[0023] The remaining structures are the same as those of Example 2.

[0024] Working principle of the present invention: In the first step, the plate to be cut is placed on a number of conveyor rollers 11. By starting the first reduction motor 12, the corresponding driving sprocket is driven to rotate, and then the chain drives the several driven sprockets to rotate synchronously, and finally drives the several conveyor rollers 11 to rotate, so that the plate moves at a uniform speed on the conveyor rollers 11. When the plate moves to the top of the several conveyor rollers 11, the two telescopic cylinders 51 are started synchronously, and the corresponding extrusion plates 53 are pushed by the corresponding telescopic rods 52. The two extrusion plates 53 move synchronously toward each other, and finally the plate is adjusted to a neatly arranged position. In the second step, first, according to the cutting requirements, the third reduction motor 32 is started to drive the double-headed lead screw 33 to rotate, thereby driving the two threaded rings 34 to move toward or away from each other, that is, through the lifting assembly 35, the corresponding cutting assembly is driven to move as a whole, and the distance between the two cutting heads 42 is finally adjusted. Then, the second reduction motor 23 is started again to drive the lead screw 22 to rotate. Under the limiting action of the moving platform 28, the guide sleeve 27 and the guide rod 25, the nut seat 26, the guide sleeve 27 and the moving platform 28 are finally forced to move along the axial direction of the guide rod 25, thereby driving the two cutting assemblies to move synchronously. In the third step, at the same time, the two cutting motors 41 are started synchronously to drive the corresponding cutting heads 42 to rotate. The protective cover 44 will come into contact with the plate in advance before the cutting head 42 comes into contact with the plate, so that the waste chips generated by the cutting head 42 when cutting the plate are only allowed to remain in the protective cover 44 and will not fly around. At the same time, the water inlet pipe 47 is connected to the output port of the external water pump in advance, and the external water pump is started to use the water inlet pipe 47 to spray water to the annular nozzle 46 in the protective cover 44. Since the annular nozzle 46 is arranged around the cutting head 42, and the contact part between the cutting head 42 and the plate is where the waste chips are generated, the waste chips can be further reduced by direct spraying, so that the annular nozzle 46 has an immersion cooling effect on the cutting head 42. In the fourth step, since the bottom of the protective cover 44 is in conflict with the top of the plate, and the cutting of the plate will produce a linear cutting groove, the mixture of waste chips and waste water (hereinafter referred to as mixed waste) generated by cutting and cooling will only flow out of the cutting groove, and at this time the plate is forced to be fixed, and the position of the cutting groove port is fixed. When the mixed waste reaches the cutting groove port, it will be forced to fall down, pass through the gap between the conveying rollers 11, and fall into the receiving hopper 61. The waste chips and waste water are preliminarily filtered through the filter screen 62 to complete the classification and collection of the mixed waste. The bottom of the receiving hopper 61 is connected to a circulating water pump to return the filtered coolant to the input end of the external water pump connected to the water inlet pipe 47.

[0025] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
