Description

Technical Field

[0001] The present invention relates to the technical field of band sawing machines, and specifically to a double-column horizontal band sawing machine. Background Art

[0002] In the field of metal processing, efficient and precise cutting processes have always been the key factors in improving production efficiency and product quality. As an important cutting device, the band sawing machine has undergone long-term development and changes. In the early days, the structure of the band sawing machine was relatively simple and its functions were relatively single, with many limitations in terms of cutting accuracy, efficiency, and stability, making it difficult to meet the diverse and complex metal processing requirements. The double-column horizontal band sawing machine emerged and gradually developed and improved under such a background; During the use of the existing double-column horizontal band sawing machine, there are still some problems, which are specifically as follows: When the existing double-column horizontal band sawing machine is in use, the conveying table arranged at the lower end can be used to convey materials. During the conveying process of the materials, the saw blade on the band sawing machine can be used to cut the materials. For example, a double-column horizontal band sawing machine disclosed in the publication number CN217942054U, on which the conveying table is arranged to convey materials, and the baffle is used to laterally limit the materials. When the saw blade on the band sawing machine is operating, it can cut the materials advancing on the conveying table. However, when it is in use, it cannot ensure the position stability of the materials in the vertical direction; This is because during the process of conveying and cutting the materials on the conveying table, the cut part of the materials is prone to warping, which affects the accuracy of the cutting position. In the existing cutting process, it is necessary for the staff to manually press the materials to prevent the materials from warping, which will increase the labor intensity of the staff and is not conducive to reducing the labor burden of the staff; In addition, when the above-mentioned existing technology uses the baffle to laterally limit the materials, it cannot adaptively adjust the position of the baffle according to the width of the materials. As a result, the staff needs to manually adjust the position of the baffle according to the width of the materials, which is time-consuming and laborious and is not conducive to improving work efficiency; Therefore, a double-column horizontal band sawing machine is needed to solve the above problems. Summary of the Invention

[0003] The purpose of the present invention is to provide a double-column horizontal band sawing machine to solve the problems raised in the above background art that when the existing double-column horizontal band sawing machine cuts materials, it is necessary for the staff to manually press the materials to prevent the materials from warping, and it cannot adaptively adjust the position of the baffle according to the width of the materials.

[0004] To achieve the above purpose, the present invention provides the following technical solutions: A double-column horizontal band sawing machine, comprising a support base and a roller conveyor table installed on its upper surface. A band sawing machine is also installed on the upper surface of the support base, and the band sawing machine is arranged across the roller conveyor table. A suspension table is fixedly connected to the lower surface of the middle part of the roller conveyor table, and a vertical limiting component is arranged on the suspension table. A lateral limiting component is also connected to the suspension table, and the lateral limiting component is connected to the vertical limiting component through a pneumatic component.

[0005] Preferably, the vertical limiting component includes a convex block movably arranged inside the suspension table, and inclined grooves penetrating through both sides thereof are arranged on the convex block. Two symmetric sliders are fixedly connected to the upper end of the convex block. Two symmetric strip-shaped through grooves are arranged on the suspension table, and the strip-shaped through grooves penetrate through the inner and outer sides of the suspension table. The two sliders respectively movably penetrate through the corresponding strip-shaped through grooves to limit the moving direction of the convex block.

[0006] Preferably, the vertical limiting component further includes a screw rod whose one end is connected to the convex block by a bearing, and the other end of the screw rod threadedly penetrates to the outside of the suspension table. A hand wheel is connected to the end of the screw rod penetrating to the outside of the suspension table. A guiding frame movably penetrates through the inclined groove, and both ends of the guiding frame respectively movably penetrate through the lower surface of the suspension table. Both ends of the guiding frame are connected by a mounting plate, and a linkage roller and a limiting roller are connected to the lower surface of the mounting plate by bearings. The mounting plate is arranged inside the saw blade of the band sawing machine.

[0007] Preferably, the guiding frame is in an n-shaped structure, and the diameter of the part of the guiding frame penetrating through the inclined groove matches the inner width of the inclined groove.

[0008] Preferably, the lateral limiting component includes four piston chambers arranged on the suspension table, and one end of a corresponding piston column is slidably connected without a gap inside each piston chamber. A second spring is arranged between one end of the piston column inside the piston chamber and the inner end of the piston chamber. The other end of the piston column movably penetrates through the corresponding piston chamber and is connected to a corresponding mounting arm, and a lateral limiting wheel set is installed at the lower end of each mounting arm.

[0009] Preferably, the lateral limiting component further includes two limiting plates fixedly connected to the suspension table, and both ends of a square frame-shaped limiting piece respectively movably penetrate through the two limiting plates. Two mutually parallel slideways are arranged on the lower surface of the suspension table, and connecting strips are slidably connected to both ends of each slideway. The four connecting strips are respectively connected to the four mounting arms, and ratchet teeth and ratchet claws that mesh with each other are arranged on the lower surface of the connecting strip and the upper surface corresponding to the limiting piece. A protrusion is arranged on the upper surface of the limiting piece close to the screw rod, and the protrusion is movably penetrated by the screw rod. A first spring movably nested outside the screw rod is arranged between the protrusion and the suspension table.

[0010] Preferably, the lengths of the ratchet teeth and the ratchet pawl are less than the displacement distance of the limiting piece, so as to completely misalign the meshing ratchet teeth and ratchet pawl, facilitating the reverse movement of the piston rod.

[0011] Preferably, the pneumatic assembly includes through grooves penetrating both sides of the mounting plate, and the positions of the through grooves correspond to the positions of the linkage rollers one by one. Two symmetrically arranged annular grooves are provided on each linkage roller, and an embedding block is slidably connected in each annular groove. The upper surface of the mounting plate is fixedly installed with a piston tube, and the two ends of the piston tube are hermetically and slidably connected to one end of the corresponding piston rod respectively. The embedding block is fixedly connected to the other end of the corresponding piston rod.

[0012] Preferably, the pneumatic assembly further includes a communicating pipe connecting the piston tubes on the same side, and the communicating pipe is connected to the two piston chambers on the same side through a three-way pipe. A one-way exhaust pipe is provided on each piston tube, and a one-way air valve is provided at the connection part between the three-way pipe and the piston chamber, so that the gas can only enter the three-way pipe through the piston chamber. A squeezing air valve communicating with the piston chamber is provided on the suspension table.

[0013] Preferably, the diameters of the linkage roller and the limiting roller are the same, and the annular groove on the linkage roller is inclined at 45° to the horizontal plane. The linkage roller is installed at both sides of the lower surface of the mounting plate.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: The double-column horizontal band saw can avoid the material from warping without manual pressing of the material by workers, which helps to reduce the labor intensity of the workers. In addition, the position of the lateral limiting wheel set can be adjusted adaptively according to the width of the material, which helps to improve the efficiency of the cutting operation: 1. By rotating the screw, the position of the convex block can be adjusted, and then the vertical position of the guiding frame can be changed through the inclined groove, so as to finally change the position of the mounting plate in the vertical direction. By changing the position of the mounting plate, the heights of the linkage roller and the limiting roller relative to the roller shaft transfer table can be changed, and then the material can be limited in the vertical direction by the linkage roller, the limiting roller and the roller shaft transfer table, avoiding the material from warping, and then the material can be cut stably. Since there is no need for manual pressing of the material in this process, the labor intensity of the workers can be reduced; 2. During the process of the material being conveyed under the action of the roller conveyor table, it will drive the linkage roller and the limit roller to rotate. When the linkage roller rotates, the piston rod can be driven to reciprocate through the annular groove and the embedded block. In cooperation with the squeeze-type air valve, the one-way exhaust pipe, and the one-way air valve provided at the connection part of the three-way pipe and the piston chamber, one end of the piston column in the piston chamber can be preferentially moved towards the inner end of the piston chamber. Furthermore, the two opposite lateral limit wheel groups can be made to approach each other. During this process, the ratchet teeth and the ratchet pawl will move relative to each other to prevent the piston column from moving reversely under the action of the second spring. When the two opposite lateral limit wheel groups come into contact with the material and the pressure reaches a certain value, the external gas will enter the piston chamber through the squeeze-type air valve, and then pass through the three-way pipe, the connecting pipe, and the piston pipe in sequence, and be discharged to the outside through the one-way exhaust pipe on the piston pipe. The above process does not require manual intervention and can adaptively adjust the position of the lateral limit wheel groups only according to the width of the material, thereby improving the efficiency of the cutting operation.

Detailed implementation manners

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1 - 10 , the present invention provides the following technical solutions: Embodiment 1: To solve the problem that in the past, a double-column horizontal band saw needed to manually press the material to prevent the material from warping, which increased the labor burden of the staff. The following technical solutions are provided specifically. A double-column horizontal band saw includes a support base 1 and a roller shaft transfer table 2 installed on its upper surface. A band saw 3 is also installed on the upper surface of the support base 1, and the band saw 3 is arranged across the roller shaft transfer table 2.

[0019] The vertical limit component includes a convex block 29 movably arranged inside the suspension table 4, and an inclined slot 30 penetrating both sides thereof is arranged on the convex block 29. Two symmetrical sliders 15 are fixedly connected to the upper end of the convex block 29.

The two sliders 15 respectively movably penetrate through the corresponding strip-shaped through slots 14 to limit the moving direction of the convex block 29. The vertical limit component further includes a screw rod 7 bearing-connected to one end of the convex block 29, and the other end of the screw rod 7 threadedly penetrates to the outside of the suspension table 4. A hand wheel 8 is connected to the end of the screw rod 7 penetrating to the outside of the suspension table 4. A guide frame 31 movably penetrates through the inclined slot 30, and both ends of the guide frame 31 respectively movably penetrate through the lower surface of the suspension table 4. Both ends of the guide frame 31 are connected by a mounting plate 11, and a linkage roller 17 and a limit roller 23 are bearing-connected to the lower surface of the mounting plate 11. The mounting plate 11 is arranged inside the saw blade of the band sawing machine 3. According to Figures 5 - 7 , during use, by rotating the hand wheel 8 to drive the screw rod 7 to rotate, during the rotation of the screw rod 7, it will move relative to the suspension table 4 threadedly connected thereto. Synchronously, it drives the convex block 29 to move relative to the suspension table 4. During the movement of the convex block 29, by using the sliding through connection between the inclined slot 30 and the guide frame 31, it can drive the mounting plate 11 connected to the guide frame 31 to move in the vertical direction, and then the linkage roller 17 and the limit roller 23 arranged on the mounting plate 11 can be moved to contact the upper surface of the material, so that when cutting the material, the material can be pressed to prevent the material from warping, which helps to ensure the stability of the cutting position.

[0020] The structural shape of the guide frame 31 is N-shaped, and the diameter of the part of the guide frame 31 penetrating through the inclined slot 30 matches the inner width of the inclined slot 30.

[0021] Embodiment 2: To solve the problem that the previous double-column horizontal band sawing machine cannot adaptively adjust the position of the baffle according to the width of the material, the following technical solution is provided. Specifically, a lateral limit component is further connected to the suspension table 4, and the lateral limit component is connected to the vertical limit component through a pneumatic component.

[0022] The lateral limiting assembly includes four piston chambers 32 provided on the suspension platform 4, and one end of a corresponding piston rod 5 is slidably connected without clearance inside each piston chamber 32. A second spring 33 is provided between one end of the piston rod 5 inside the piston chamber 32 and the inner end of the piston chamber 32. The other end of the piston rod 5 movably penetrates through the corresponding piston chamber 32 and is connected to the corresponding mounting arm 6. A lateral limiting wheel set 9 is installed at the lower end of each mounting arm 6. The lateral limiting assembly further includes two limiting plates 13 fixedly connected to the suspension platform 4, and the two limiting plates 13 are respectively movably penetrated by the two ends of the square frame-shaped limiting piece 12. Two parallel slideways 24 are provided on the lower surface of the suspension platform 4, and a connecting bar 25 is slidably connected to both ends of each slideway 24. The four connecting bars 25 are respectively connected to the four mounting arms 6, and ratchet teeth and ratchet claws that mesh with each other are provided on the lower surface of the connecting bar 25 and the corresponding upper surface of the limiting piece 12. A protrusion is provided on the upper surface of the limiting piece 12 close to the screw rod 7, and the protrusion is movably penetrated by the screw rod 7. A first spring 22 movably nested outside the screw rod 7 is provided between the protrusion and the suspension platform 4. The lengths of the ratchet teeth and the ratchet claws are less than the displacement distance of the limiting piece 12, so that the mutually meshing ratchet teeth and ratchet claws are completely misaligned, facilitating the reverse movement of the piston rod 5. According to Figure 6 and Figure 9 , when in use, when the opposite lateral limiting wheel sets 9 approach each other, the opposite lateral limiting wheel sets 9 can be prevented from moving away from each other through the ratchet teeth and the ratchet claws, and the second spring 33 provided inside the piston chamber 32 can facilitate the reset of the lateral limiting wheel sets 9 after the ratchet claws and the ratchet teeth are completely misaligned.

[0023] The pneumatic assembly includes through grooves 16 penetrating both sides of the mounting plate 11, and the positions of the through grooves 16 correspond one by one to the positions of the linkage rollers 17. Two symmetrical annular grooves 18 are provided on each linkage roller 17, and an insertion block 19 is slidably connected inside each annular groove 18. A piston tube 21 is fixedly installed on the upper surface of the mounting plate 11, and one end of a corresponding piston rod 20 is slidably connected without clearance to the two open ends of the piston tube 21 respectively. The insertion block 19 is fixedly connected to the other end of the corresponding piston rod 20. The pneumatic assembly further includes a connecting pipe 26 connecting the piston tubes 21 on the same side, and the connecting pipe 26 is connected to the two piston chambers 32 on the same side through a tee pipe 27. A one-way exhaust pipe 28 is provided on each piston tube 21. A one-way air valve is provided at the part where the tee pipe 27 is connected to the piston chamber 32, so that gas can only enter the tee pipe 27 through the piston chamber 32. A squeeze-type air valve 10 communicating with the piston chamber 32 is provided on the suspension platform 4. According to Figure 4 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9, during use, since the linkage roller 17 and the limiting roller 23 press against the upper surface of the material, when the material moves under the action of the roller shaft transfer table 2, it will drive the linkage roller 17 and the limiting roller 23 to rotate. When the linkage roller 17 rotates, the annular groove 18 and the embedded block 19 thereon can drive the piston rod 20 to reciprocate, thereby continuously squeezing the gas in the piston tube 21 to the outside through the one-way exhaust pipe 28, and continuously sucking the gas in the piston chamber 32. After the gas in the piston chamber 32 is sucked, the pressure inside it decreases, which drives the opposite side lateral limiting wheel sets 9 to approach each other. When the opposite side lateral limiting wheel sets 9 come into lateral contact with the material and cannot move further, when the pressure in the piston chamber 32 reaches a certain value, it will cause the outside gas to enter the piston chamber 32 through the extrusion type air valve 10 (the extrusion type air valve 10 can be opened only after having a certain pressure, and then the two sides of the extrusion type air valve 10 are communicated. This is the prior art and will not be described in detail here), so as to be sucked into the piston tube 21 and then discharged to the outside through the one-way exhaust pipe 28; When it is necessary to reset the side lateral limiting wheel sets 9, only need to pull the limiting piece 12 to completely stagger the ratchet and the ratchet teeth, then the side lateral limiting wheel sets 9 can be reset under the action of the second spring 33.

[0024] The linkage roller 17 and the limiting roller 23 have the same diameter, and the annular groove 18 on the linkage roller 17 is inclined at 45° to the horizontal plane. The linkage roller 17 is installed at both sides of the lower surface of the mounting plate 11.

[0025] The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
