Description

Technical Field

[0001] This utility model belongs to the technical field of bolt cold heading machines, and specifically relates to a self-lubricating bolt cold heading machine. Background Technology

[0002] A cold heading machine is a type of equipment specifically designed for the mass production of fasteners such as bolts. The main working principle of a cold heading machine is to shape steel billets into a specific shape at room temperature. It is commonly used to manufacture parts such as bolts, nuts, nails, rivets, and steel balls.

[0003] A search revealed that in the prior art, Chinese Patent Publication No. CN202062031 U, authorized on December 7, 2011, discloses a bolt cold heading machine, including a machine body, an heading head slider, a die box, and a drive mechanism. The heading head slider is located within a slide rail inside the machine body and is connected to the drive mechanism via a crankshaft connecting rod. The die box is located opposite the heading head slider and is fixed to the support shaft of the machine body via bearings. A gear and a positioning wheel are also mounted on the support shaft, with the positioning wheel at the innermost position and the gear in the middle. The positioning wheel, gear, and die box are fastened together to form a single unit. The gear is connected to the drive mechanism, and the positioning wheel is connected to the drive mechanism via a positioning mechanism. This embodiment of the tiltable heading head significantly shortens the crankshaft length of the crankshaft connecting rod, increases the working torque, and improves efficiency.

[0004] However, the device still has the following drawbacks: the above embodiment does not have a rapid lubrication effect. If it cannot have a rapid lubrication effect, it will lead to insufficient lubrication. Insufficient lubrication will increase the friction between machine parts, leading to increased wear. This will not only affect the service life of the machine, but may also affect the continuity of production and the quality of the product. Utility Model Content

The other end of the spiral telescopic pipe 38 is connected to the input end of the connecting plate 25.

[0027] Working principle: The entire lubrication device is cleverly integrated into the base 1 of the cold heading machine, which not only saves space, but also makes the coordinated work between the components smoother through reasonable mechanical design, thereby improving the stability and reliability of the entire system.

[0028] The storage box 16 is placed in the storage slot 14. The box cover 18 can be opened to clean the inside of the storage box 16. The lubricating oil usage in the storage box 16 can be observed through the observation slot 15 and the transparent observation window 17. The lubricating oil usage can be checked at any time to ensure timely replenishment and avoid equipment damage caused by insufficient lubricating oil. This facilitates maintenance and monitoring.

[0029] The oil outlet pipe 34 is placed on the arc-shaped support plate 23, and the arc-shaped limiting plate 24 is placed above the oil outlet pipe 34. The arc-shaped limiting plate 24 and the arc-shaped support plate 23 are in contact. The screw 27 is threaded through the through hole 26 and connected to the nut 28, so that the arc-shaped support plate 23 and the arc-shaped limiting plate 24 are fixed. The fixed column 30 is rotated to drive the screw 31 to rotate in the threaded hole 29, while driving the pressure plate 32 to descend. The spring 33 is stretched, and the bottom of the pressure plate 32 is attached to the outer wall of the oil outlet pipe 34 to fix the oil outlet pipe 34.

[0030] When the water pump 36 starts, the lubricating oil in the storage box 16 is transported through the transport pipe 37, then through the spiral telescopic pipe 38, and finally through the delivery pipe 35 into the oil outlet pipe 34, where it is output.

[0031] The electric telescopic rod 19 moves the first fixed block 20 and simultaneously moves the second motor 21. The second motor 21 moves the second fixed block 22 and simultaneously moves the arc-shaped shelf 23. The arc-shaped shelf 23 moves the oil outlet pipe 34. The second motor 21 rotates the second fixed block 22 and simultaneously rotates the arc-shaped shelf 23. The arc-shaped shelf 23 rotates the oil outlet pipe 34, adjusting the position and angle of the oil outlet pipe 34 so that the output end of the oil outlet pipe 34 is close to the place that needs to be lubricated for lubrication.

[0032] The first motor 7 drives the lead screw 6 to rotate, while simultaneously moving the slider 8 within the slide groove 4. The slider 8 moves the moving plate 9, which in turn moves the mounting block 13. The mounting block 13 then moves the oil outlet pipe 34, allowing for lubrication of multiple areas on the cold heading machine body 2 that require lubrication. This improves flexibility and lubrication efficiency. The electric push rod 39 moves the connecting block 40 up and down, while simultaneously moving the mounting block 13 up and down. The mounting block 13 then moves the oil outlet pipe 34 up and down, adjusting the height of the oil outlet pipe 34.

[0033] Through the cooperation of components such as the first motor 7, electric push rod 39, electric telescopic rod 19 and second motor 21, the automatic delivery of lubricating oil and the automatic adjustment of the position of the oil outlet pipe 34 are realized, which not only reduces the need for manual operation, but also improves the accuracy and efficiency of lubrication work.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
