Description

Technical Field

[0001] The utility model relates to the technical field of sawing machines, in particular to an auxiliary device for sawing machines. Background Art

[0002] In wood processing, metal sawing and other industries that require precise size sawing, sawing machines are one of the commonly used equipment. However, traditional sawing machines have the following inconveniences during operation:

[0003] First, the sawing platforms of existing sawing machines are relatively small. When sawing long materials, the long materials are suspended in the air. If there is no external force to hold the materials, the sawing surface will be tilted to a certain extent. At the same time, the material discharge end of the sawing machine needs to arrange staff to receive the materials in advance, otherwise the materials will fall to the ground after sawing.

[0004] Secondly, the existing sawing machines generally do not have the function of accurately measuring the size of the sawn material. Before sawing, most of them need to make size marks on the metal material in advance, and then saw according to the marks. This method is time-consuming and labor-intensive, very inconvenient, and most of the sawing is done by manually pressing the end to be sawed. If it is not pressed during sawing, it is easy for the material to vibrate, especially when the material to be sawed has edges and corners, it is easy to cause mechanical damage to the workers;

[0005] In view of this, there is an urgent need for an auxiliary device for a sawing machine that can solve the above problems. Utility Model Content

[0010] Preferably, the auxiliary sawing board is provided with auxiliary sawing scales.

[0011] Preferably, a material pushing assembly fixedly connected to the support frame located at the feeding end of the sawing machine is provided, and the material pushing assembly includes a U-shaped shell, two groups of pushing rollers, two groups of pushing shafts and multiple groups of pressure assemblies.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Please see attached Figure 1-3 , an auxiliary device for a sawing machine, comprising:

[0027] A sawing machine 1, two groups of auxiliary feeding components 2 and an auxiliary sawing component 3, wherein the sawing machine 1 is provided with a sawing tool 10, and the two groups of auxiliary feeding components 2 are respectively fixedly connected to the feeding end and the discharging end of the sawing machine 1, and the auxiliary feeding component 2 includes a support frame 20 and a plurality of auxiliary rollers 21, and the plurality of auxiliary rollers 21 are bearing-connected to the support frame 20, and the auxiliary sawing component 3 is fixedly connected to the support frame 20 located on one side of the discharging end of the sawing machine 1.

[0028] By adding auxiliary feeding components 2 at both ends of the sawing machine 1, the original sawing platform of the sawing machine 1 is extended in disguise. In this way, when the work material is sawed, the tail end will no longer be hammered down due to its own gravity, which indirectly avoids the situation where the work material cut is an inclined surface. At the same time, the use of the auxiliary feeding component 2 at the discharge end also avoids the situation where the sawed work material falls directly to the ground, thereby avoiding the situation where the sawed work material falls to the ground and causes impact damage.

[0029] The auxiliary sawing assembly 3 comprises an auxiliary sawing plate 30, an L-shaped baffle plate 31 and a locking handle 32. The auxiliary sawing plate 30 is fixedly connected to the support frame 20 in the horizontal direction, and a strip slide groove 300 is provided on the auxiliary sawing plate 30. A bolt 310 fixedly connected to the auxiliary sawing plate 30 is provided on a side wall of the L-shaped baffle plate 31 close to the auxiliary sawing plate 30, and an end of the bolt 310 away from the L-shaped baffle plate 31 passes through the strip slide groove 300 and is threadedly connected to the locking handle 32. By adding the auxiliary sawing plate 30 to the original bracket 20, the position of the L-shaped baffle plate 31 movably connected to the auxiliary sawing plate 30 can be freely adjusted. For example, the sawing sample is placed between the sawing tool 10 and the L-shaped baffle plate 31. By adjusting the position of the L-shaped baffle plate 31, the distance between the sawing tool 10 and the L-shaped baffle plate 31 is controlled. In subsequent sawing, there is no need to mark the materials to be sawed one by one, and the materials of the same length as the sample can be sawed.

[0030] Specifically, the auxiliary sawing board 30 is provided with an auxiliary sawing scale 301 ; considering that there is no sample but only sawing size in actual application, in this case, the position of the L-shaped baffle 31 can be adjusted according to the auxiliary sawing scale 301 on the auxiliary sawing board 30 .

[0031] Specifically, the support frame 20 located at the feeding end of the sawing machine 1 is provided with a material pushing assembly 4 fixedly connected thereto, and the material pushing assembly 4 includes a U-shaped shell 40, two groups of pushing rollers 41, two groups of pushing shafts 42 and multiple groups of pressure assemblies 43. The U-shaped shell 40 is fixedly connected to the support frame 20, one end of the two groups of pushing shafts 42 is connected to the inner wall of the U-shaped shell 40 by bearings, and the other end passes through the two groups of pushing rollers 41 and then passes through the U-shaped shell 40 respectively, the two groups of pushing shafts 42 are fixedly connected to the two groups of pushing rollers 41 respectively, the two groups of pushing shafts 42 are located at one end of the outer side of the U-shaped shell 40 and are connected by a transmission belt 44, and the multiple groups of pressure assemblies 43 are fixedly connected to the side walls of the pushing rollers 41 respectively;

[0032] Considering that most of the actual applications are manual measurement of material cutting and sawing, and the error is large, secondary correction is required later, and it is easy for the tail end of the work material to lift up and injure people during the sawing process. Therefore, a material pushing component 4 is set. First, the U-shaped shell 40 and the pressure component 43 therein can form downward pressure on the work material to ensure that the tail end of the work material will not lift up during the sawing process. Secondly, through the multiple groups of pressure components 43 provided on the two groups of pushing rollers 41, the contact with the material is alternately completed, and the material is driven to move toward the direction of the sawing machine 1 under the action of resistance. In this process, the rotation of the pushing shaft 42 is easier to control, that is, the distance of the work material advancement is easier to control, thereby achieving the purpose of accurately controlling the sawing length.

[0033] Specifically, the pressure assembly 43 includes a pressure plate 430, multiple groups of outer tubes 431, multiple groups of inner tubes 432 and multiple groups of springs 433. The multiple groups of outer tubes 431 are fixedly connected to the curved side wall of the pushing roller 41, and the spring 433 is located in the outer tube 431. One end of the inner tube 432 is slidably connected in the outer tube 431, and the other end is fixedly connected to the pressure plate 430. When the pressure plate 430 is in a vertical downward state, it contacts the work material and forms compression on the spring 433 under the action of the work material. When the pressure plate 430 rotates with the pushing roller 41, the reverse elastic force of the spring 433 drives the work material to move toward the direction of the sawing machine 1. It should be noted that the multiple pressure assemblies 43 on the two groups of pushing rollers 41 should be in contact with the work material in a staggered state to avoid the situation where the contact surface between the pressure plate 430 and the work material cannot drive the work material forward due to the angle problem, thereby causing the pushing roller 41 to idle.

[0034] Specifically, one of the propulsion shafts 42 is located at one end outside the U-shaped shell 40 and is provided with a motor and a motor PLC controller that matches it; in order to further achieve the purpose of accurately controlling the propulsion distance of the work material, a motor is used to drive the propulsion shaft 42, and the motor PLC controller is used as a control system to achieve the purpose of accurately controlling the number of revolutions of the motor, thereby achieving the purpose of accurately controlling the propulsion distance of the work material.

[0035] Specifically, when the pressure assembly 43 is in a vertically downward state, the length of the pressure assembly 43 is greater than the height of the recessed part of the U-shaped shell 40; when the pressure assembly 43 is in a vertically downward state, its length is greater than the height of the recessed part of the U-shaped shell 40. This setting is to ensure that the pressure assembly 43 will inevitably contact the work material to avoid idling of the push roller 41.

[0036] Specifically, the support frame 20 located at the discharge end of the sawing machine 1 is provided with a position limiting component 5 movably connected thereto, and the position limiting component 5 is located between the sawing tool 10 and the L-shaped baffle 31, and includes a position limiting plate 50, two groups of position limiting rods 51 and two groups of arc-shaped baffles 52, and the position limiting plate 50 is movably connected to the support frame 20, and is provided with a plurality of fixing holes 500 matching the position limiting stems 51, and the two groups of the position limiting rods 51 are respectively fixedly connected to the concave side walls of the two groups of the arc-shaped baffles 52; considering that in the actual sawing process, when the material is pushed by manpower, the material may slip without being controlled during sawing, and may cause injury, so an additional position limiting component 5 is provided, and the positions of the two groups of arc-shaped baffles 52 are adjusted by inserting the position limiting rods 51 into different fixing holes 500, thereby forming a position limit for the front end of the work material to be cut, thereby avoiding the work material slipping during sawing.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
