Description

Technical Field

[0001] This utility model relates to the technical field of steel pipe processing equipment, and in particular to a steel pipe shaping and processing device. Background Technology

[0002] Stainless steel pipe is a hollow, long, round steel material. Because it is lighter in weight while maintaining the same bending and torsional strength, it is widely used, mainly for industrial pipelines in petroleum, chemical, medical, food, light industry, and machinery, as well as mechanical structural components. After cutting, the cut surface of stainless steel pipe has burrs, which can easily scratch users. In addition, the ends of stainless steel pipe are easily damaged by impact, resulting in unevenness. Therefore, the ends of stainless steel pipe need to be processed.

[0003] Existing steel pipe forming devices are mainly designed for clamping positions and methods, such as clamping at both ends to tighten the steel pipe. However, when the steel pipe is long, only supporting at both ends cannot fully guarantee the processing quality. Utility Model Content

[0004] The purpose of this invention is to provide a steel pipe shaping and processing device, which solves the technical problem that the quality of shaping and processing of long steel pipes cannot be fully guaranteed in the prior art.

[0005] This application discloses a steel pipe shaping and processing device, including:

[0006] Base;

[0007] The shaping mechanism is mounted on the base;

[0008] A limiting mechanism is installed on the base, and the limiting mechanism is located inside the shaping mechanism;

[0009] The limiting mechanism includes:

[0010] At least two center frame assemblies are installed at intervals on the base;

[0011] A clamping assembly is mounted on the base and located outside the central frame assembly;

[0012] A limiting component is installed on the base, and the bottom of the limiting component cooperates with the top of the clamping component.

[0013] This application adds a central support assembly to support the middle of a long steel pipe, with one central support assembly located at 1 / 3 and the other at 2 / 3, thereby reducing the pipe's vibration and ensuring the quality of the pipe end forming process.

[0014] Based on the above technical solution, the embodiments of this application can be further improved as follows:

[0015] Furthermore, the clamping assembly includes:

[0016] The clamping hydraulic cylinder is vertically positioned.

[0017] A steel pipe bracket is installed at the output end of the clamping hydraulic cylinder, and the top of the steel pipe bracket is V-shaped. The advantage of this step is that the steel pipe bracket is used to support the steel pipe, and the clamping and fixing are completed in conjunction with the subsequent limiting components.

[0018] Furthermore, the limiting component includes:

[0019] A limiting bracket is installed on the base;

[0020] A limit cylinder is vertically mounted on the limit bracket;

[0021] A limiting unit is installed at the output end of the limiting cylinder, and the bottom of the limiting unit cooperates with the top of the steel pipe bracket. The beneficial effect of this step is that by pushing the limiting cylinder, the limiting unit is driven to move down and cooperate with the steel pipe bracket to complete the clamping of the steel pipe.

[0022] Furthermore, the limiting unit includes:

[0023] A limiting seat is installed on the piston rod end of the limiting cylinder;

[0024] A transverse track is installed at the bottom of the limiting seat;

[0025] Two clamping blocks are slidably mounted on the transverse track at intervals;

[0026] Two stop blocks are installed at a distance from the bottom of the limiting seat, and the stop blocks are located outside the clamping block;

[0027] Two adjusting bolts are installed on the stop block in a one-to-one correspondence, and the ends of the adjusting bolts are in contact with the outer side of the stop block;

[0028] A spring is positioned between the stop block and the clamping block. The advantage of this step is that by adjusting the bolt, the position of the clamping block can be changed, thereby ensuring the clamping of steel pipes of different sizes.

[0029] Furthermore, the opposite sides of the clamping block are inclined surfaces. The advantage of this step is that it facilitates better clamping of the steel pipe.

[0030] Furthermore, the central frame assembly includes:

[0031] A fixing seat is provided on the base;

[0032] The center frame, installed on the fixed base, has the advantage of enabling the steel pipe to be clamped by the center frame, reducing radial runout and thus ensuring the processing quality of the product.

[0033] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0034] 1. This application adds a center frame assembly to fix the middle of the steel pipe, which can reduce vibration and jumping during end forming and thus ensure the processing quality of the steel pipe.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0048] To better understand the above technical solutions, the following will provide a detailed description of the technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0049] Example 1:

[0050] like Figure 1-3 As shown in the embodiment of this application, a steel pipe shaping and processing device is disclosed. This shaping and processing device is mainly for shaping the ends of steel pipes, specifically, end shaping and processing.

[0051] like Figure 1 As shown, the specific structure of this application includes:

[0052] Base 1, which is an existing base, is equipped with a track for installing subsequent shaping mechanisms, thereby enabling the adjustment of the relative positions of the two shaping mechanisms;

[0053] The shaping mechanism 2 is installed on the base 1. The shaping mechanism 2 is an existing device, including a chuck, a motor and a grinding disc, etc. The grinding disc and the motor are installed on the aforementioned track and can move relative to each other along the track. The grinding disc is used to grind the end of the steel pipe. This is an existing mechanism and will not be described in detail here.

[0054] The limiting mechanism 3 is installed on the base 1 and is located inside the forming mechanism 2. Specifically, the limiting mechanism 3 is located between the chuck and the grinding disc to realize the processing of the end of the steel pipe.

[0055] The limiting mechanism 3 includes:

[0056] At least two center frame assemblies 301 are installed at intervals on the base 1. The center frame assembly 301 is used to clamp the middle of the steel pipe and provide additional radial support during processing to suppress bending deformation, vibration and displacement.

[0057] The clamping assembly 302 is installed on the base 1 and is located outside the center frame assembly 301. It is mainly for supporting the end of the steel pipe.

[0058] A limiting component 303 is installed on the base 1. The limiting component 303 is located outside the clamping component 302, and the end of the limiting component 303 cooperates with the top of the clamping component 302.

[0059] This application uses a center frame assembly 301 to clamp the middle part of the steel pipe to ensure the stability of the steel pipe during processing, while the subsequent clamping assembly 302 and limiting assembly 303 are used to fix the end of the steel pipe to ensure the quality of the shaping process.

[0060] like Figure 3 As shown, the central frame assembly 301 in this application can be an existing structure or may include:

[0061] A fixing seat 304 is disposed on the base 1. The fixing seat 304 serves as a support for installing the subsequent center frame.

[0062] The center frame 305 is mounted on the fixed base 304. The center frame 305 is an existing structure used to clamp the middle of the steel pipe and reduce the runout of the steel pipe. It is especially suitable for processing longer steel pipes.

[0063] In one embodiment, the clamping assembly 302 of this application includes:

[0064] The clamping hydraulic cylinder 306 is vertically positioned.

[0065] The steel pipe bracket 307 is installed at the output end of the clamping hydraulic cylinder 306, and the top of the steel pipe bracket 307 is V-shaped. The steel pipe bracket 307 in this application is used to provide V-shaped support, which, together with the subsequent limiting component 303, presses downward to further ensure the stability of the steel pipe, thereby ensuring the accuracy of processing.

[0066] Among them, such as Figure 2 As shown, the limiting component 303 includes:

[0067] The limiting bracket 308 is installed on the base 1 and is relatively high, which facilitates the downward movement of the limiting cylinder to press it in place.

[0068] The limiting cylinder 309 is vertically mounted on the limiting bracket 308;

[0069] The limiting unit 310 is installed at the output end of the limiting cylinder 309, and the bottom of the limiting unit 310 cooperates with the top of the steel pipe bracket 307 to complete the clamping action.

[0070] Because the dimensions of the steel pipes to be processed may vary, the limiting unit 310 needs to be designed to be adjustable. The limiting unit 310 in this application is manually adjustable, and its specific structure includes:

[0071] The limiting seat 311 is installed on the piston rod end of the limiting cylinder 309;

[0072] A transverse track 312 is installed at the bottom of the limiting seat 311;

[0073] Two clamping blocks 313 are slidably mounted on the transverse track 312 at intervals;

[0074] Two stop blocks 314 are installed at intervals at the bottom of the limiting seat 311, and the stop blocks 314 are located outside the clamping block 313. The stop blocks 314 serve as supports for adjustment, which facilitates the movement of the subsequent adjusting bolts.

[0075] Two adjusting bolts 315 are installed on the stop block 314 one to one, and the end of the adjusting bolt 315 contacts the outside of the stop block 314. Through the design of the adjusting bolt 315, the clamping block 313 can be pushed to move, thereby completing the clamping.

[0076] A spring 316 is disposed between the stop block 314 and the clamping block 313, which pulls the clamping block 313 so that the gap of the clamping block 313 is adjustable. Preferably, there are two springs 316.

[0077] Specifically, the opposite sides of the clamping block 313 are inclined surfaces, which facilitates the downward clamping of the steel pipe.

[0078] Further explanation is provided regarding this application:

[0079] This application pertains to the shaping process of the ends of steel pipes. The ends of steel pipes may have burrs or uneven surfaces, so shaping equipment can be used for processing.

[0080] This type of steel pipe has a relatively long section, thus requiring fixation using the center frame assembly described in this application to ensure concentricity and reduce runout. To further ensure processing stability, this application provides a clamping assembly and a limiting assembly at the end of the steel pipe for clamping. The clamping assembly uses a clamping hydraulic cylinder to push the steel pipe support upwards to support the steel pipe, while the limiting assembly uses a limiting cylinder to push the limiting unit downwards to clamp the steel pipe. To accommodate steel pipes of different sizes, this application also allows manual adjustment of the adjusting bolts to adjust the gap of the clamping blocks, thereby better clamping the steel pipe. Springs assist in ensuring the position of the clamping blocks, i.e., pulling the clamping blocks, in conjunction with the adjusting bolts, so that the clamping blocks can be stably positioned in the corresponding location.

[0081] Numerous specific details are set forth in this specification. However, it will be understood that embodiments of this invention may be practiced without these specific details. In some instances, well-known methods, structures, and techniques have not been shown in detail so as not to obscure the understanding of this specification.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.
