Description

Technical Field

[0001] The utility model belongs to the technical field of band sawing machines, and particularly relates to a guiding hand structure of a band sawing machine. Background Technique

[0002] The guiding hand of a sawing machine, also called a guiding head, is an important component on a band sawing machine, mainly used to control and guide the movement method of a saw blade, ensuring the stable and precise operation of the saw blade during work.

[0003] The saw wheels are generally inclined. By adjusting the orientation of the saw teeth of the saw band through the guiding hand of the sawing machine, sawing is facilitated. In actual use, when the saw blade moves through the gap formed by two alloy pieces of the guiding hand of the sawing machine, without lubricating fluid for lubrication, the friction is large, heat is easily generated, and the generated debris cannot be removed, resulting in a faster wear rate of the two alloys. The debris accumulates inside the guiding hand. The existing solution usually uses the method of externally spraying lubricating fluid to achieve the purposes of lubrication, heat dissipation, and flushing. However, such a method only has an effect on the surface, and the effect on the internal structure is not very obvious. The wear rate of the alloy becomes faster, and the consumables are replaced relatively frequently. For example, the authorized announcement number CN 203621623 U discloses a saw band guiding head of a sawing machine, and the authorized announcement CN2430258Y discloses a guiding mechanism for a band saw blade. The guiding head structures disclosed in the above patents do not have an internal lubricating channel structure and need to be equipped with a cooling system outside to reduce the temperature of the saw blade and prevent overheating. Secondly, the design at the bottom of the guiding hand and the guiding wheel does not meet the actual use requirements of the saw blade, and the inventor improves it. Summary of the Invention

[0004] Based on the technical defects existing in the background technique, the utility model provides a guiding hand structure of a band sawing machine. A lubricating fluid supply channel is arranged inside the seat body structure of the guiding hand, used for lubricating, cooling, and flushing between the alloy and the saw blade, preventing the saw blade from overheating, reducing wear, and at the same time improving the bottom of the seat body of the guiding hand and the installation part of the guiding wheel to adapt to the saw blade guiding.

[0005] In order to achieve the above object, the technical solution adopted by the utility model is as follows:

[0006] A guiding hand structure of a band sawing machine includes a guiding hand seat body, characterized in that: an alloy clamping piece placement groove is arranged at the bottom of the guiding hand seat body, and the bottom of the guiding hand seat body is flush with the bottom of the alloy clamping piece, completely wrapping the alloy clamping piece, so that the alloy clamping piece is more stable and sufficient when clamping the saw blade. A supply channel is arranged inside the guiding hand seat body, and the supply channel is divided into two branches. The outlet of the first branch is located on the left side wall of the placement groove, and the outlet of the second branch is located on the right side wall of the placement groove.

[0007] Furthermore, the injection hole of the supply channel is located at the top of the guiding hand seat body, and the injection hole is connected to a lubricating fluid supply pipeline to inject lubricating liquid into the supply channel.

[0008] Further, the two branches are in the same vertical plane or not in the same vertical plane within the guiding hand seat body, and the arrangement of the branches can be designed according to the actual situation or the processing method.

[0009] Further, through holes are formed in the alloy clamping piece corresponding to the outlet of the branch, so that the lubricating fluid can enter between the alloy and the saw blade conveniently.

[0010] Further, the thickness of the guiding wheel installed on the guiding hand seat body is half of the width of the saw blade, preferably 21 mm. At the same time, the installation part of the guiding wheel is extended to adapt to the reasonable space required by the increase of the guiding wheel, so that the guiding effect on the saw blade is more stable and sufficient.

[0011] The following beneficial effects can be obtained through the above technical solutions:

[0012] The utility model is improved on the basis of the existing sawing machine guiding hand. A lubricating fluid supply channel is opened inside the matrix or body of the sawing machine guiding hand, and the lubricating oil is supplied to the alloy and the saw blade through the supply channel, so as to achieve the purposes of lubrication, cooling and flushing. In this way, the internal structure completely replaces the external cooling system, the overall structure is simple, the use effect is good, the temperature of the saw blade is reduced, overheating is prevented, and the stability of the sawing condition of the saw blade is ensured.

[0013] The development and design of the utility model completely save the production cost of the user, reduce the alloy wear rate, reduce the frequency of replacing consumables, and also reduce the requirements for equipping a cooling system. Description of the Drawings

[0024] The following further describes the present utility model with reference to the accompanying drawings:

[0025] As Figure 1-8 shown, a band sawing machine guide hand structure includes a guide hand seat body 1. An alloy clamping piece placing groove 3 is provided at the bottom of the guide hand seat body for placing two alloy clamping pieces. The bottom of the guide hand seat body is flush with the bottom of the alloy clamping piece, completely wrapping the alloy clamping piece, so that the alloy clamping piece is more stable and sufficient when clamping the saw blade. A supply channel 5 is provided in the guide hand seat body. The supply channel is divided into two branches. The outlet A 9 of the first path 6 is located on the right side wall of the placing groove, and the outlet B 8 of the second path 7 is located on the left side wall of the placing groove. At the same time, the right alloy clamping piece is provided with a through hole corresponding to the outlet A 9, and the left alloy clamping piece is provided with a through hole corresponding to the outlet B 8. The injection hole of the supply channel is located at the top of the guide hand seat body. The injection hole 4 is connected to a lubricating liquid supply pipeline to inject lubricating liquid into the supply channel.

[0026] For the internal supply channel of the band sawing machine guide hand structure, the layout or setting of the two branches can be in the same vertical plane or in non - same vertical planes. The specific structure is explained as follows: Embodiment

[0027] Figure 6 As shown, it is a cross - sectional view of the band sawing machine guide hand structure, showing the layout mode of the supply channel in the same vertical plane. Such a mode makes the outlet positions on the left and right side walls correspond, and the lubricating liquid is concentrated in one area for lubrication, cooling and flushing. Its structure is that the supply channel extends downward from the top injection hole 4. After reaching a certain position, it extends to the left and right directions along the first path and the second path respectively. Finally, the outlet of the first path is set at the right side wall of the placing groove, and the outlet of the second path is set at the left side wall of the placing groove. At the same time, the two alloy clamping pieces also have liquid through holes, so that the lubricating liquid supply channel and the liquid through holes reach between the saw blade and the alloy clamping piece, achieving the purpose of lubrication, cooling and flushing. Embodiment

[0028] For the layout mode in the same vertical plane in Embodiment 1, which leads to the determination of the outlet and the concentration of the lubricating liquid, so the supply channel designed in this Embodiment 2 has a layout mode in different vertical planes, Figure 7 and 8As shown, the supply channel and the first path can be arranged in a common vertical plane, while the second path can be arranged in another vertical plane. A horizontal channel 10 needs to be used in the second path to ensure the smoothness of the second path. Such a structure changes the relative position of the outlet. The advantage of this is that the liquid outlets on the left and right sides of the placement groove are arranged in a staggered manner, so that the lubricating fluid is evenly discharged into the entire structure of the saw blade and the two alloy clamping pieces, achieving a better lubricating, cooling and flushing effect.

[0029] In each of the above embodiments, the thickness of the guide wheel installed on the guide hand seat body is 21 mm. At the same time, the installation part of the guide wheel is extended to adapt to the reasonable space required due to the increase of the guide wheel, so that the guiding effect on the saw blade is more stable and sufficient.

[0030] All of the above are the preferred embodiments of the present invention. For those of ordinary skill in the art of this technology, without departing from the principle of the present invention, the modifications of various equivalent forms of the present invention all fall within the protection scope of the appended claims of this application.
