It has certain strength and toughness, and can meet the performance requirements of different scenarios through appropriate processing technology.
[0003] Existing technology cannot achieve online straightening during the cold drawing process. Once the steel bends, the cold drawing process usually needs to be stopped, the steel removed from the cold drawing equipment, and then transferred to a special straightening equipment for straightening, which interrupts the production process and reduces production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a device for strengthening medium carbon steel by cold drawing, which is an alternative to quenching and tempering, in order to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for strengthening medium carbon steel by cold drawing, replacing quenching and tempering, comprising a cold drawing equipment body, and further comprising:
[0006] A transmission assembly is placed on the body of the cold drawing equipment. The transmission assembly includes a sliding block slidably connected to the body of the cold drawing equipment, a first transmission rod fixedly connected to the sliding block, a transmission block slidably connected to the first transmission rod, a first connecting rod fixedly connected to the transmission block, a transmission plate fixedly connected to the first connecting rod, a second connecting rod fixedly connected to the transmission plate, a fixed rod fixedly connected to the second connecting rod, and a straightening block rotatably connected to the fixed rod.
[0007] The second transmission rod is rotatably connected to the body of the cold drawing equipment. A fourth connecting rod is fixedly connected to the second transmission rod. The fourth connecting rod is slidably connected to the straightening block, and the straightening block is rotatably connected to the body of the cold drawing equipment.
[0008] Furthermore, the second transmission rod is rotatably connected to the body of the cold drawing equipment via a second rotating shaft, and the straightening block is rotatably connected to the fixed rod via a first rotating shaft.
[0009] The above technical solution is adopted: a second transmission rod is rotatably connected to the body of the cold drawing equipment through a second rotating shaft. When the second transmission rod rotates, it can move the straightening block to rotate on the fixed rod.
[0010] Furthermore, a horizontal plate is fixedly connected inside the body of the cold drawing equipment, and the transmission block is slidably connected to the horizontal plate on the body of the cold drawing equipment.
[0011] The above technical solution is adopted: a horizontal plate is fixedly connected inside the body of the cold drawing equipment, which facilitates the use of the horizontal plate to limit the movement of the transmission block during use.
[0012] Furthermore, an electric telescopic rod is fixedly connected to the bottom of the sliding block, and the side of the electric telescopic rod away from the sliding block is fixedly connected to the body of the cold drawing equipment.
[0013] The above technical solution is adopted: by fixing an electric telescopic rod to the bottom of the sliding block, it is convenient to use the electric telescopic rod to drive the sliding block during use.
[0014] Furthermore, a damper is fixedly connected to the bottom of the sliding block, and the side of the damper away from the sliding block is fixedly connected to the body of the cold drawing equipment.
[0015] By adopting the above technical solution, the vibration of the sliding block can be minimized during use by incorporating damping.
[0016] Furthermore, the second transmission rod is slidably connected to the body of the cold drawing equipment.
[0017] The above technical solution is adopted: by setting a second transmission rod to slide and connect with the body of the cold drawing equipment, the second transmission rod is prevented from being blocked by the body of the cold drawing equipment and unable to move during use.
[0018] Furthermore, a third connecting rod is fixedly connected to one end of the second transmission rod away from the transmission block, and the third connecting rod is slidably connected to the correction block.
[0019] The above technical solution is adopted: by setting a third connecting rod, it is convenient to drive the correction block.
[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0021] In this invention, when bending occurs during the cold drawing of steel pipe, the electric telescopic rod is immediately activated without stopping the machine. Its telescopic movement causes the sliding block fixedly connected to it to rise or fall. The first transmission rod fixedly connected to the sliding block moves synchronously with it and slides in the inclined hole on the transmission block. At this time, due to the limitation of the transmission block by the horizontal plate, the transmission block can only slide along the horizontal plate towards or away from the electric telescopic rod. The sliding of the transmission block is transmitted sequentially through the first connecting rod, the transmission plate, the second connecting rod, and the fixed rod, which drives the displacement and angle adjustment of the straightening block, applies force to the bent steel pipe, and restores it to a straight state, ensuring continuous production and greatly improving production efficiency. This solves the problem in the prior art that the existing technology cannot quickly straighten steel pipes. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0032] Example:
[0033] like Figures 1-5 As shown, this utility model provides a technical solution: a device for strengthening medium carbon steel by cold drawing, replacing quenching and tempering, comprising a cold drawing equipment body 1, and further comprising:
[0034] Transmission assembly 2 is placed on the body 1 of the cold drawing equipment. Transmission assembly 2 includes a sliding block 22 that is slidably connected to the body 1 of the cold drawing equipment. A first transmission rod 21 is fixedly connected to the sliding block 22. A transmission block 23 is slidably connected to the first transmission rod 21. A first connecting rod 24 is fixedly connected to the transmission block 23. A transmission plate 25 is fixedly connected to the first connecting rod 24. A second connecting rod 26 is fixedly connected to the transmission plate 25. A fixed rod 27 is fixedly connected to the second connecting rod 26. A straightening block 28 is rotatably connected to the fixed rod 27.
[0035] The second transmission rod 3 is rotatably connected to the body 1 of the cold drawing equipment. A fourth connecting rod 33 is fixedly connected to the second transmission rod 3. The fourth connecting rod 33 is slidably connected to the straightening block 28. The straightening block 28 is rotatably connected to the body 1 of the cold drawing equipment.
[0036] In this invention, when bending occurs during the cold drawing of the steel pipe, the electric telescopic rod 210 immediately starts without stopping the machine. Its telescopic movement drives the sliding block 22, which is fixedly connected to it, to rise or fall. The first transmission rod 21, fixedly connected to the sliding block 22, moves synchronously with it and slides within the oblique hole on the transmission block 23. At this time, due to the limitation of the transmission block 23 by the horizontal plate, the transmission block 23 can only slide along the horizontal plate towards or away from the electric telescopic rod 210. The sliding of the transmission block 23 is sequentially transmitted through the first connecting rod 24, the transmission plate 25, the second connecting rod 26, and the fixed rod 27, driving the straightening block 28 to adjust its displacement and angle, quickly applying force to the bent steel pipe, restoring it to a straight state, ensuring continuous production, and significantly improving production efficiency.
[0037] Furthermore, such as Figures 1 to 5 As shown, the second transmission rod 3 is rotatably connected to the cold drawing equipment body 1 via the second rotating shaft 32, and the straightening block 28 is rotatably connected to the fixed rod 27 via the first rotating shaft 29. When the angle of the straightening block 28 needs to be adjusted during the operation of the equipment, the second transmission rod 3 can rotate flexibly around the second rotating shaft 32 as the axis, thereby causing the straightening block 28 to rotate around the first rotating shaft 29 on the fixed rod 27. This allows the straightening block 28 to act on the steel pipe from different directions with appropriate force, effectively dealing with various bending deformations that occur during the cold drawing process of the steel pipe, and ensuring that the final straightness of the steel pipe meets the production requirements.
[0038] like Figure 2 as well as Figure 3 As shown, a horizontal plate is fixedly connected inside the body 1 of the cold drawing equipment, and the transmission block 23 is slidably connected to the horizontal plate on the body 1 of the cold drawing equipment. When the equipment is running, when the transmission block 23 needs to move during the power transmission process, due to its sliding connection with the horizontal plate, it can only slide smoothly along the preset trajectory of the horizontal plate, thus eliminating the possibility that the transmission block 23 may deviate from the normal path due to uneven force or external interference.
[0039] like Figures 1 to 5 As shown. An electric telescopic rod 210 is fixedly connected to the bottom of the sliding block 22. The side of the electric telescopic rod 210 away from the sliding block 22 is fixedly connected to the body 1 of the cold drawing equipment. When the steel pipe in the cold drawing process shows signs of bending and needs to be straightened immediately, the control system quickly issues a command, and the electric telescopic rod 210 responds quickly, extending or shortening precisely according to the preset program, driving the sliding block 22 closely connected to it to lift or lower in a predetermined direction and speed.
[0040] The bottom of the sliding block 22 is fixedly connected to a damper. The side of the damper on the sliding block 22 away from the sliding block 22 is fixedly connected to the body 1 of the cold drawing equipment. Through its special structural design and material properties, the damper can effectively absorb and convert the vibration energy received by the sliding block 22, and reduce the vibration amplitude of the sliding block 22 as much as possible. This not only avoids hard collisions between the sliding block 22 and adjacent parts caused by vibration, reducing component wear and extending the service life of the equipment, but also ensures the positional accuracy of the sliding block 22 during movement, prevents displacement deviation caused by vibration from having an adverse effect on the entire transmission system, and ensures the accuracy of the straightening operation.
[0041] like Figure 4 As shown, the second transmission rod 3 is slidably connected to the body 1 of the cold drawing equipment. When the second transmission rod 3 is transmitting power, rotating the straightening block 28, etc., due to its sliding connection with the body 1 of the cold drawing equipment, it can flexibly adapt to its own force changes and the movement requirements of the surrounding components, and freely adjust its own position, effectively avoiding the embarrassing situation of being blocked by the body 1 of the cold drawing equipment due to structural interference.
[0042] like Figure 5 As shown, a third connecting rod 31 is fixedly connected to the end of the second transmission rod 3 away from the transmission block 23. The third connecting rod 31 is slidably connected to the straightening block 28. When the equipment is running, if the second transmission rod 3 rotates or changes displacement based on the straightening requirement, the third connecting rod 31 can closely follow its movement and transmit power to the straightening block 28. Moreover, due to the flexibility of the sliding connection, the third connecting rod 31 can adjust its contact position with the straightening block 28 according to the real-time posture of the straightening block 28 to ensure the effectiveness of power transmission.
[0043] Working principle: such as Figures 1 to 5As shown, when the workpiece is bent after grinding, the electric telescopic rod 210 is directly activated to lift the sliding block 22. At this time, the first transmission rod 21 slides on the inclined hole on the transmission block 23. Under the guidance of the inclined hole and the limiting effect of the horizontal plate, the transmission block 23 slides towards the side closer to the electric telescopic rod 210, which causes the first connecting rod 24 to drive the second connecting rod 26 and the fixed rod 27 to slide. The fixed rod 27 continues to slide towards the side closer to the cold drawing equipment body 1, so that one side of the straightening block 28 gradually abuts against the cold drawing equipment body 1. At this time, the straightening block 28 is driven to change angle, which acts on the steel pipe, causing the steel pipe to bend.
[0044] When the straightening block 28 is reset, the electric telescopic rod 210 resets first. Under the action of the pulling force, the sliding block 22 will gradually slide down, causing the transmission block 23 to be driven to slide away from the sliding block 22. This causes the end of the second transmission rod 3 away from the cold drawing equipment body 1 to be driven to tilt up, so that the straightening block 28 is pushed against and rotated to complete the reset. At this time, the cold drawing equipment body 1 can be used normally.
[0045] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
