Description

Technical Field

[0001] The utility model belongs to the technical field of cold drawing machines, and in particular relates to an intelligent and efficient cold drawing machine for stainless steel pipes. Background Art

[0002] The steel pipe cold drawing machine is a device specially used for secondary processing of ferrous and non-ferrous metal bars and rough pipes after hot rolling and extrusion at room temperature. It is a key processing equipment for producing small-caliber, precision, thin-walled, high-mechanical-performance pipes. Its core working principle relies on the reciprocating motion of the oil cylinder, and the pulling operation of the casing and drill pipe is realized through this mechanism.

[0003] From the perspective of structural design, steel tube cold drawing machines can be roughly divided into two types: three-seat separate type and frame type according to the different bed structures. In terms of transmission methods, it covers a variety of types such as chain type, hydraulic transmission type and rack type. These different transmission methods have their own characteristics, but what they have in common is that they all need to reset the cold drawing car after the cold drawing operation is completed in order to carry out the next cold drawing operation. However, this reset process often introduces a long downtime, because only when the cold drawing car is reset can the next round of cold drawing be carried out. This downtime not only affects production efficiency, but also increases production costs.

[0004] Therefore, it is very necessary to invent an intelligent and efficient cold drawing machine for stainless steel pipes. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an intelligent and efficient cold drawing machine for stainless steel pipes, comprising a cold drawing base, a cold drawing sliding frame, a cold drawing car driving mechanism, a guide rail and a cold drawing car, wherein the cold drawing base, the cold drawing sliding frame and the cold drawing car driving mechanism are installed together; the cold drawing car is slidably installed on the cold drawing sliding frame through the guide rail and is fixedly connected to the cold drawing car driving mechanism, and the cold drawing car driving mechanism is located above the two cold drawing cars;

[0006] The cold-drawn car driving mechanism includes a bracket base, a driving component, a bidirectional reciprocating screw, a linkage shaft, a dust cover and a screw nut. The bracket base is fixed to the cold-drawn base and the cold-drawn sliding frame. The driving component is fixedly installed on the outside of the bracket base. The output end of the driving component is fixedly connected to one end of one of the bidirectional reciprocating screws. Two bidirectional reciprocating screws are provided. The two bidirectional reciprocating screws are rotatably installed on the cold-drawn base and the bracket base respectively, and the two bidirectional reciprocating screws are fixed by a linkage shaft; the dust cover is sleeved on the outside of the bidirectional reciprocating screw and fixed to the cold-drawn base, the bracket base and the screw nut; the bidirectional reciprocating screw is fixedly connected to the cold-drawn car through the screw nut.

[0007] Preferably, the cold-drawn sliding frame is located on both sides of the cold-drawn car, and the cold-drawn car is slidably installed on the two cold-drawn sliding frames through rollers and guide rails. A steel pipe clamping mechanism is installed on the cold-drawn car, and the steel pipe passes through the two cold-drawn cars in sequence and is allowed to be clamped and fixed by the clamping mechanism.

[0008] Preferably, two sections of threads with opposite rotation directions are simultaneously arranged on the bidirectional reciprocating screw, and the two sections of threads with opposite rotation directions are superimposed in a cross manner, and the bidirectional reciprocating screw can drive the screw nut to perform reciprocating motion by unidirectional rotation.

[0009] Preferably, the diameter of the linkage shaft is greater than the diameter of the bidirectional reciprocating screw, and the linkage shaft is located between the two cold-drawn machines.

[0010] Preferably, the dust cover is a cylindrical corrugated cover, which is located on both sides of the linkage shaft and outside the bidirectional reciprocating screw. Dust covers are installed between the cold-drawn base and the screw nut and between the bracket base and the screw nut.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model abandons the traditional commonly used chain, hydraulic transmission and rack transmission methods, and instead innovatively introduces a screw transmission mechanism. In order to further improve production efficiency, two cold-drawn cars are specially added on this basis. This design allows the screw mechanism to drive the two cold-drawn cars to reciprocate only through unidirectional rotation, and the two cold-drawn cars can cold-draw the steel pipes in an alternating manner. This unique design significantly reduces the length of the cold-drawn car's reciprocating motion, thereby effectively avoiding the long downtime caused by the cold-drawn car's reset, significantly improving production efficiency and reducing production costs.

[0020] As attached Figure 1 To Attachment Figure 3 As shown:

[0021] The utility model provides an intelligent and efficient cold drawing machine for stainless steel pipes, comprising a cold drawing base 1, a cold drawing sliding frame 2, a cold drawing car driving mechanism 3, a guide rail 4 and a cold drawing car 5, wherein the cold drawing base 1, the cold drawing sliding frame 2 and the cold drawing car driving mechanism 3 are installed together; the cold drawing car 5 is slidably installed on the cold drawing sliding frame 2 through the guide rail 4, and is fixedly connected to the cold drawing car driving mechanism 3, and the cold drawing car driving mechanism 3 is located above the two cold drawing cars 5.

[0022] The cold-drawing car driving mechanism 3 includes a bracket base 31, a driving component 32, a bidirectional reciprocating screw 33, a linkage shaft 34, a dust cover 35 and a screw nut 36. The bracket base 31 is fixed to the cold-drawing base 1 and the cold-drawing sliding frame 2. The driving component 32 is fixedly installed on the outside of the bracket base 31. The output end of the driving component 32 is fixedly connected to one end of one of the bidirectional reciprocating screws 33. Two bidirectional reciprocating screws 33 are provided. The two bidirectional reciprocating screws 33 are rotatably installed on the cold-drawing base 1 and the bracket base 31 respectively, and the two bidirectional reciprocating screws 33 are fixed by the linkage shaft 34; the dust cover 35 is sleeved on the outside of the bidirectional reciprocating screw 33 and is fixed to the cold-drawing base 1, the bracket base 31 and the screw nut 36; the bidirectional reciprocating screw 33 is fixedly connected to the cold-drawing car 5 through the screw nut 36. The unique structural design of the cold-drawing car driving mechanism 3 can drive the two cold-drawing cars 5 to perform displacement movements in two different directions simultaneously, thereby realizing an alternating cold-drawing mechanism for the steel pipe.

[0023] Embodiment 1:

[0024] Specifically, the cold-drawn sliding frame 2 is located on both sides of the cold-drawn car 5. The cold-drawn car 5 is stably slidably installed on the two cold-drawn sliding frames 2 through rollers and guide rails 4, ensuring the stability and accuracy of the cold-drawn car 5 during the sliding process. On the cold-drawn car 5, a special steel pipe clamping mechanism is installed. These clamping mechanisms can firmly clamp the steel pipe to ensure the stability of the steel pipe during the cold drawing process. The steel pipe passes through the two cold-drawn cars 5 in turn and is clamped and fixed by the clamping mechanism in turn, making the cold drawing process of the steel pipe more efficient and reliable. Combined with the cold-drawn car driving mechanism 3 mentioned above, when the cold-drawn car driving mechanism 3 is in operation, the two cold-drawn cars 5 can alternately reciprocate to cold-draw the steel pipe. This design not only reduces the length of the reciprocating motion of the cold-drawn car 5, but also avoids the long downtime caused by the resetting of the cold-drawn car, thereby significantly improving production efficiency.

[0025] Specifically, two sections of threads with opposite rotation directions are simultaneously arranged on the bidirectional reciprocating screw 33, and the two sections of threads with opposite rotation directions are superimposed in a cross manner, so that when the bidirectional reciprocating screw 33 rotates in one direction, it can drive the screw nut 36 matched therewith to reciprocate through its threads with opposite rotation directions, and the screw nut 36 reciprocates. This mechanism greatly simplifies the operation process of the cold drawing machine, while improving the stability and reliability of the equipment. Combined with the cold drawing car 5 and the steel pipe clamp mechanism mentioned above, the entire cold drawing process can be completed with higher efficiency, reducing the downtime caused by the resetting of the cold drawing car 5, thereby improving the overall production efficiency.

[0026] Specifically, the diameter of the linkage shaft 34 is larger than the diameter of the bidirectional reciprocating screw 33, which not only ensures sufficient strength and stability, but also facilitates the coordination and transmission with components such as the cold-drawn car 5. The linkage shaft 34 is located between the two cold-drawn cars 5, so that the linkage shaft 34 can produce a linkage effect with the two cold-drawn cars 5 at the same time. When the bidirectional reciprocating screw 33 rotates unidirectionally, the two cold-drawn cars 5 can reciprocate synchronously through the transmission of the linkage shaft 34, which not only realizes the alternating cold drawing of the steel pipe, but also plays a role in limiting the screw nut 36.

[0027] Specifically, the dust cover 35 is a cylindrical corrugated cover, which not only has a large accommodating space, but also has a certain degree of scalability and elasticity due to the corrugated design, and can adapt to the deformation requirements of different working states. The dust cover 35 is located on both sides of the linkage shaft 34 and the outside of the bidirectional reciprocating screw 33, which can effectively prevent dust and impurities generated during the cold drawing process from entering the interior of the equipment and protect the key components of the screw from pollution and wear. The dust cover 35 is installed between the cold drawing base 1 and the screw nut 36 and between the bracket base 31 and the screw nut 36.

[0028] Embodiment 2:

[0029] The cold drawing machine is composed of a cold drawing base 1, a cold drawing sliding frame 2, a cold drawing car driving mechanism 3, a guide rail 4 and a cold drawing car 5. The cold drawing base 1, the cold drawing sliding frame 2 and the cold drawing car driving mechanism 3 are installed together to form a stable working platform.

[0030] Cold drawing lathe drive mechanism 3:

[0031] The bracket base 31 is fixed on the cold drawing base 1 and the cold drawing sliding frame 2, and serves as the installation basis for the driving component 32 and the bidirectional reciprocating screw 33. The output end of the driving component 32 (motor) is connected to one end of one of the bidirectional reciprocating screws 33 to provide power for the screw. The bidirectional reciprocating screw 33 is the core component of the cold drawing car drive mechanism, on which there are two sections of threads with opposite rotation directions, which are superimposed in a cross manner. When the screw rotates unidirectionally, the two screw nuts 36 are driven to reciprocate through their threads with opposite rotation directions. The linkage shaft 34 connects the two bidirectional reciprocating screws 33 to ensure that they rotate synchronously. The diameter of the linkage shaft 34 is larger than the diameter of the screw to ensure sufficient strength and stability. The dust cover 35 is sleeved on the outside of the bidirectional reciprocating screw 33 to prevent dust and impurities from entering the interior of the equipment and protect key components.

[0032] Cold drawn car 5:

[0033] The cold drawing car 5 is stably mounted on the cold drawing sliding frame 2 through rollers and guide rails 4 to ensure the stability and accuracy of the sliding process. A steel pipe clamping mechanism is installed on the cold drawing car 5, which can firmly clamp the steel pipe to ensure stability during the cold drawing process. The steel pipe passes through the two cold drawing cars 5 in sequence and is alternately clamped and fixed by the two clamping mechanisms.

[0034] Embodiment three:

[0035] Working principle:

[0036] When the driving component 32 is started, it drives one of the two-way reciprocating screws 33 to rotate in one direction. Due to the design of the threads on the two-way reciprocating screw 33 with opposite rotation directions, and the synchronization of the linkage shaft 34, the two screw nuts 36 will move in opposite directions respectively (i.e., one screw nut 36 moves to the left, and the other screw nut 36 moves to the right). The screw nuts 36 are fixedly connected to the cold-drawn car 5, so the two cold-drawn cars 5 will synchronously perform displacement movements in two different directions. When one cold-drawn car 5 completes the cold-drawing operation, the driving component 32 can be used to control the reverse rotation of the screw, so that the two cold-drawn cars 5 return to the initial position and prepare for the next cold-drawing operation. The dust cover 35 plays a dust-proof role in the entire working process to protect the interior of the equipment from pollution.

[0037] Utilizing the technical solution described in the utility model, or those skilled in the art designing similar technical solutions inspired by the technical solution of the utility model to achieve the above-mentioned technical effects, all fall within the protection scope of the utility model.
