Abstract
Description
Technical Field
[0001] This utility model relates to the field of nut manufacturing and processing, and in particular to an oil fume removal mechanism for cold heading machines. Background Technology
[0002] Cold heading oil is required when cold heading nuts. It has a lubricating effect, which can effectively prevent roughening and scratches on the surface of the workpiece, thereby improving the surface finish of the workpiece and reducing the scrap rate. At the same time, it has excellent anti-wear properties, which can effectively reduce friction between tools and parts, thereby extending their service life. It also has a cooling effect, which can effectively reduce the temperature of the processed metal and the mold, and prevent workpiece deformation and thermal shock of the mold caused by rapid cooling.
[0003] Because cold heading oil is added, oil fumes are generated during cold heading. Therefore, an oil fume removal mechanism is installed to absorb the cold heading oil fumes in the air. The oil fume removal mechanism includes an oil fume collector and a conveying pipe. The conveying pipe includes a main pipe and branch pipes connected to the main pipe. The main pipe is connected to the collector, and the smoke inlet of the branch pipe is close to the discharge port of the cold heading machine. In order to reduce the gap between the smoke inlet of the conveying pipe and the discharge port of the cold heading machine and to better draw the smoke into the conveying pipe, the smoke inlet is aligned as close as possible to the discharge port. After alignment, the branch pipe is kept stationary. Generally, the branch pipe is tied to the cold heading machine frame with wire, which is cumbersome to operate. Utility Model Content
[0004] The purpose of this invention is to provide an oil fume removal mechanism for a cold heading machine. Its advantages are that it is easy to fix the oil fume suction branch pipe of the conveying pipe, and the branch pipe can remain stable when the pipe opening is aligned with the outlet of the cold heading machine for smoke extraction.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] The fume removal mechanism for cold heading machines includes the cold heading machine, a fume collector, and conveying pipes. Multiple cold heading machines are located in the production workshop. Each cold heading machine is equipped with a chain conveyor, which includes a frame and chain plates. A connecting pipe connects the fume collector to the conveying pipes. The conveying pipes include a main pipe and branch pipes connected to it. The main pipe is fixed to the workshop wall by fasteners. The branch pipes include flexible hoses and rigid pipes connected to them. The rigid pipes are located near the cold heading machines, and their openings are close to the cold heading machines. Near the discharge end of the chain conveyor, a support rod is hinged to the side wall of the chain conveyor frame. The support rod is fixedly connected to an installation rod, and the installation rod is rotatably connected to a lead screw. The installation rod and the lead screw slider are respectively fixedly connected to limit rods. An adjustment mechanism is provided between the support rod and the side wall of the chain conveyor frame. Two triangular supports are fixedly connected to the outer shell of the cold heading machine, and an adjustment mechanism is provided on the two triangular supports. The adjustment mechanism is connected to a support shaft, and a rigid tube is in contact with the support shaft and the limit rod respectively.
[0007] Using the above technical solution, the rigid tube is placed between the two limiting rods of the mounting rod, and then the opening of the rigid tube is brought close to the discharge end of the chain conveyor. By rotating the support rod through the adjustment mechanism, the limiting rod fixed to the mounting rod comes into contact with the rigid tube. By rotating the lead screw, the lead screw slider drives the upper limiting rod to move, so that the limiting rod comes into contact with the rigid tube and exerts a force on the rigid tube, thereby clamping the rigid tube between the two limiting rods. Then, by moving the support shaft through the second adjustment mechanism, the support shaft comes into contact with the rigid tube. By supporting different parts of the rigid tube through the support shaft and the two limiting rods, the opening of the rigid tube can be stably kept close to the discharge end of the chain conveyor. Compared with binding the rigid tube to the cold heading machine with wire, the operation is more convenient.
[0008] Preferably, the adjusting mechanism includes a connecting rod, a connecting block, and a screw. One end of the connecting rod is hinged to a support rod, and the other end of the connecting rod is hinged to a connecting block. The connecting block is slidably connected to the side wall of the chain conveyor frame. The screw is threadedly connected to the side wall of the chain conveyor frame and rotatably connected to the connecting block.
[0009] Using the above technical solution, when the screw is turned, the screw pushes the connecting block 1 to move. The moving connecting block 1 drives the support rod to rotate through the connecting rod. The support rod drives the mounting rod to rotate. The mounting rod drives the limiting rod connected to it to approach the rigid pipe and make contact with the rigid pipe.
[0010] Preferably, the upper surfaces of the two triangular supports on the cold heading machine are respectively provided with T-shaped grooves. The second adjustment mechanism includes a bolt, a nut, and a second connecting block. There are two bolts, and the tail of each bolt is respectively embedded in the two T-shaped grooves and slidably connected to the first triangular support. The bolt passes through the second connecting block, and the nut is located on the upper part of the second connecting block. The nut is threadedly connected to the bolt. The two ends of the support shaft are respectively rotatably connected to the second connecting blocks of the two supports.
[0011] Using the above technical solution, loosen the bolts on the two triangular brackets to reduce the pressure on the connecting block 2. Then move the connecting block 2, which will move the bolts, nuts and support shaft. Move the shaft closer to the rigid pipe and make contact with the rigid pipe. Then tighten the bolts to press the connecting block 1, thereby fixing the support shaft.
[0012] Preferably, the fixing components are a second triangular bracket and a U-bolt. There are multiple second triangular brackets, which are fixedly connected to the wall of the production workshop. The main pipe is located on the upper part of the second triangular bracket and is fixedly connected to the second triangular bracket by the U-bolt.
[0013] Using the above technical solution, the main pipe is placed on the upper part of the second triangular bracket, the U-bolt is fitted around the main pipe, and the two ends of the U-bolt pass through the second triangular bracket. Nuts are screwed on the two ends of the U-bolt, and the nuts contact the bottom of the second triangular bracket, thereby fixing the main pipe to the second triangular bracket.
[0014] Preferably, the system includes a support frame, which includes multiple support columns that are fixedly connected to the ground. A U-shaped frame is fixedly connected to the end of each support column, and the main pipe is placed in the U-shaped frame.
[0015] By adopting the above technical solution, the main pipe is supported by a support frame, which increases the stability of the main pipe. Attached Figure Description

[0024] See Figures 1 to 3 This system is used for removing oil fumes from cold heading machines. It includes a cold heading machine 1, an oil fume collector 3, and conveying pipes. Multiple cold heading machines 1 are located in the production workshop. Each cold heading machine 1 is equipped with a chain conveyor 2, which includes a frame and chain plates. A connecting pipe connects the oil fume collector 3 to the conveying pipes. The conveying pipes include a main pipe 4 and branch pipes connected to the main pipe 4. Multiple triangular brackets 20 are fixed to the walls of the production workshop. The main pipe 4 is located on top of the triangular brackets 20, and U-bolts 21 are used to secure the main pipe 4, with both ends of the U-bolts 21 passing through the triangular brackets 20. Nuts are screwed onto both ends of the U-bolts 21, contacting the bottom of the triangular brackets 20, thus fixing the main pipe 4 to the triangular brackets 20. Multiple support columns are fixedly connected to the floor of the production workshop, with U-shaped frames fixedly connected to the ends of the support columns. The main pipe 4 is placed within the U-shaped frames.
[0025] See Figure 3 , Figure 5 and Figure 6 The branch pipe includes a flexible hose 5 and a rigid pipe 6 connected to the flexible hose 5. The rigid pipe 6 is close to the cold heading machine 1, and the opening of the rigid pipe 6 is close to the discharge end of the chain conveyor 2. A support rod 7 is hinged to the side wall of the chain conveyor 2 frame. A connecting rod 13 is hinged to the support rod 7. A connecting block 14 is hinged to the end of the connecting rod 13 away from the support rod 7. The connecting block 14 is slidably connected to the side wall of the chain conveyor 2 frame. A screw 15 is threaded to the side wall of the chain conveyor 2 frame. The end of the screw 15 is rotatably connected to the connecting block 14. An installation rod 8 is fixedly connected to the end of the support rod 7. The installation rod 8 has a cavity through which a lead screw 9 passes. The lead screw 9 is rotatably connected to the installation rod 8. Limit rods 10 are fixedly connected to the sliding blocks of the installation rod 8 and the lead screw 9, respectively.
[0026] See Figures 1 to 4Two triangular supports 11 are fixedly connected to the outer casing of the cold heading machine 1. T-shaped grooves 17 are respectively opened on the upper surface of the two triangular supports 11. The machine also includes bolts 18, nuts 19, connecting blocks 16 and support shafts 12. There are two bolts 18, and the tail of each bolt 18 is respectively embedded in the two T-shaped grooves 17 and slidably connected to the triangular supports 11. The bolts 18 pass through the connecting blocks 16. The nuts 19 are located on the upper part of the connecting blocks 16 and are threadedly connected to the bolts 18. The two ends of the support shaft 12 are rotatably connected to the connecting blocks 16 of the two supports respectively, and the rigid tubes 6 are in contact with the support shaft 12 and the limiting rods 10 respectively.
[0027] Working principle: Place the rigid pipe 6 between the two limiting rods 10 of the mounting rod 8, and then bring the pipe opening of the rigid pipe 6 close to the discharge end of the chain conveyor 2. Turn the screw 15, and the screw 15 pushes the connecting block 14 to move. The moving connecting block 14 drives the support rod 7 to rotate through the connecting rod 13. The support rod 7 drives the mounting rod 8 to rotate. The mounting rod 8 drives the limiting rod 10 connected to it to move closer to the rigid pipe 6. Turn the lead screw 9, and the slider of the lead screw 9 drives the upper limiting rod 10 to move, so that the limiting rod 10 contacts the rigid pipe 6 and exerts a force on the rigid pipe 6, thereby clamping the rigid pipe 6 with the two limiting rods 10. Then loosen the bolts 18 on the two triangular brackets 11 on the cold heading machine 1 to reduce the pressure on the connecting block 16. Then move the connecting block 16, and the connecting block 16 drives the bolts 18, nuts 19 and support shaft 12 to move. The support shaft 12 moves closer to the rigid pipe 6 and contacts the rigid pipe 6. Tighten bolt 18 to press connecting block 2 16, thereby fixing support shaft 12. Support shaft 12 and two limit rods 10 support different parts of rigid pipe 6, so that the pipe opening of rigid pipe 6 can be stably kept close to the discharge end of chain conveyor 2. Compared with using wire to tie rigid pipe to cold heading machine, operation is more convenient.
