Description

Technical Field

[0001] This utility model discloses a pipe expansion device, which belongs to the field of automation equipment technology. Background Technology

[0002] In existing technologies, the process of enlarging small pipes relies on manual operation. The commonly used enlarging mechanism uses a bench vise as a fixing point. After clamping the manual enlarging device in the vise, the conical metal head is aligned with the pipe opening, and the opening is enlarged by manually rotating and pressing. Existing equipment is insufficient, suffering from drawbacks such as difficulty in controlling clamping force, inaccurate positioning, difficulty in ensuring consistency and precision in enlarging, low efficiency, high labor intensity for operators, and safety hazards.

[0003] Automated and intelligent processing equipment has become an urgent need in the industry. Therefore, developing a system that can automatically, accurately, and efficiently enlarge the inner diameter of small pipes is particularly important. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a pipe expansion device, which facilitates the fixing of round pipes, thereby realizing the automated and high-precision expansion of the pipe's inner diameter.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a pipe expansion device, including a support platform, an expansion mechanism, a clamping module, a clamping module, and a limiting module. The expansion mechanism, the clamping module, and the clamping module are all fixedly connected to the support platform. The clamping module and the limiting module are located on one side of the clamping module, and the expansion mechanism is located on the other side of the clamping module. The limiting module is detachably fixedly connected to the support platform. The clamping module can be tightened / unlocked. The expansion mechanism is provided with an expansion head. When the clamping module is tightened, a cylindrical through hole is formed. The expansion head faces the through hole of the clamping module. When the expansion mechanism is activated, the expansion head can move back and forth along the axis of the through hole.

[0006] Furthermore, in the aforementioned pipe reaming device, the reaming mechanism includes a drive mechanism and a reaming head, the reaming head being connected to the movable end of the drive mechanism, and the drive mechanism being a reciprocating motor or a cylinder.

[0007] Furthermore, in the aforementioned pipe expansion device, the pressing module includes a cylinder, an upper pressing block, a lower pressing block, and a fixed bracket. The fixed bracket is fixedly connected to a support platform, the cylinder is fixedly connected to the fixed bracket, the upper pressing block is fixedly connected to the movable part of the cylinder, and the lower pressing block is fixedly connected to the support platform. A semi-circular tube notch is formed at the bottom of the upper pressing block and the top of the lower pressing block. The upper and lower pressing blocks are positioned correspondingly. The cylinder can drive the upper pressing block to move vertically up and down. The downward pressure of the cylinder causes the upper and lower pressing blocks to be in a pressed state. The semi-circular tube notch of the upper pressing block and the semi-circular tube notch of the lower pressing block combine to form a cylindrical notch.

[0008] Furthermore, in the aforementioned pipe expansion device, the clamping module includes a base and two semi-circular tubes. The base is fixedly connected to a support platform, one of the semi-circular tubes is fixedly connected above the base, and the two semi-circular tubes are connected by a hinge. When the two semi-circular tubes are closed, they form a cylindrical through hole. The cylindrical through hole and the cylindrical notch formed between the upper and lower pressure blocks are on the same axis.

[0009] Furthermore, in the aforementioned pipe expansion device, the limiting module comprises a base plate, a left side plate, a right side plate, and a front plate. The left and right side plates are connected to the left and right sides of the base plate, and the front plate is connected to the front side of the base plate. The left and right sides of the front plate are connected to the left and right side plates. The base plate is provided with limiting mounting holes, and the support platform is provided with mounting holes. The limiting mounting holes and the mounting holes can be fixedly connected by bolts, so that the limiting module is fixedly connected to the support platform.

[0010] Furthermore, in the aforementioned pipe expansion device, the support platform is provided with multiple mounting holes.

[0011] Furthermore, in the aforementioned pipe reaming device, the reaming head is made of hard alloy material, and the free end of the reaming head forms a conical structure.

[0012] The advantages of this invention are as follows: This invention uses the plane of the support platform as a reference plane for positioning, and fixes and guides the pipe through the clamping and pressing modules, keeping the pipe at the same level and preventing pipe deviation. This solves the problem of hole enlargement failure caused by pipe assembly deviation. Hole enlargement is driven by a motor, and the possibility of over-extrusion is avoided by controlling the stroke of the extrusion head, ensuring the quality of hole enlargement. The hole enlargement head is made of hard alloy material, and the head is designed with a conical structure adapted to the inner diameter of the pipe, ensuring a smooth and precise hole enlargement process. It is convenient for single-person operation, saves labor, improves work efficiency, and increases the pass rate. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Element in the present invention is referred to as being "fixed to" or "set on" another element; it may be directly on another element or may have an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may have an intervening element present. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0020] like Figure 1 and Figure 2 As shown, this utility model provides a pipe expansion device, including a support platform 1, an expansion mechanism 2, a clamping module 3, a clamping module 4, and a limiting module 5. The expansion mechanism 2, the clamping module 3, and the clamping module 4 are all fixedly connected to the support platform 1, and the limiting module 5 is fixedly connected to the support platform 1 in a detachable manner.

[0021] Specifically, such as Figure 1 and Figure 2 As shown, the reaming mechanism 2 includes a drive mechanism and a reaming head. The reaming head is connected to the movable end of the drive mechanism. The drive mechanism is a reciprocating motor, and the forward distance of the reaming head is set by controlling the stroke through a hydraulic press head. The reaming head is made of hard alloy material, and its free end forms a tapered structure adapted to the inner diameter of the pipe, ensuring a smooth and precise reaming process. It should be noted that a cylinder can also be used instead of a reciprocating motor.

[0022] like Figures 1 to 3As shown, the supporting module 4 includes a base 41 and two semi-circular tubes 42. The base 41 is fixedly connected to the support platform 1, and one of the semi-circular tubes 42 is fixedly connected above the base 41. The two semi-circular tubes 42 are connected by a hinge 43. When the two semi-circular tubes 42 are closed, they form a cylindrical through hole that matches the diameter of the tube to be enlarged, allowing the tube to be inserted into the cylindrical through hole formed by the two semi-circular tubes 42.

[0023] like Figure 1 and Figure 4 As shown, the clamping module includes a cylinder 31, an upper pressure block 321, a lower pressure block 322, and a fixed bracket 33. The fixed bracket 33 is fixedly connected to the support platform 1. The cylinder 31 is fixedly connected to the fixed bracket. The upper pressure block 321 is fixedly connected to the movable part of the cylinder 31. The lower pressure block 322 is fixedly connected to the support platform 1. The bottom of the upper pressure block 321 and the top of the lower pressure block 322 both have semi-circular tube notches. The upper pressure block 321 and the lower pressure block 322 are positioned opposite each other. The cylinder 31 can drive the upper pressure block 321 to move vertically up and down. The cylinder 31 presses down so that the upper pressure block 321 and the lower pressure block 322 are in a clamped state. The semi-circular tube notch of the upper pressure block 321 and the semi-circular tube notch of the lower pressure block 322 combine to form a cylindrical notch. The round tube to be enlarged can be confined within the notch of the clamping module to prevent the round tube from shaking.

[0024] like Figure 1 and Figure 5 As shown, the limiting module 5 includes a base plate, a left side plate, a right side plate, and a front plate. The left and right side plates are connected to the left and right sides of the base plate, and the front plate is connected to the front side of the base plate, with its left and right sides connected to the left and right side plates. The base plate has limiting mounting holes 51, and the support platform 1 has mounting holes 11. The limiting mounting holes 51 and 11 can be fixedly connected by bolts, thus fixing the limiting module 5 to the support platform. The support platform 1 has multiple mounting holes, allowing the position of the limiting module 5 to be adjusted according to the actual length of the circular tube.

[0025] The working principle of this utility model is as follows: Figure 1 and Figure 2As shown, a limiting module 5 is installed on the support platform 1 according to the length of the round tube, so that one end of the round tube is in the semi-circular tube notch of the lower pressing block 322 of the pressing module 3, and the other end abuts against the front plate of the limiting module 5. The part of the round tube between the limiting module 5 and the pressing module 3 is supported by the holding module 2. The holding module 2 is closed, and then the cylinder 31 is activated, and the upper pressing block 321 and the lower pressing block 322 of the pressing module 3 are pressed together. The cylindrical through hole formed by the clamping module 2 and the cylindrical through hole formed by the pressing module 3 are on the same axis, thereby fixing the round tube and ensuring that the round tube is in a horizontal state. The driving mechanism of the hole-expanding mechanism is activated, which allows the hole-expanding head to expand the hole of the round tube. When the driving mechanism is activated, the hole-expanding head moves along the axis of the cylindrical notch formed by the pressing module. After the hole-expanding operation is completed, the driving mechanism retracts, the cylinder 31 is lifted, and the round tube can be taken out.

[0026] As can be seen from the above description, this utility model uses the plane of the support platform as the reference plane for positioning. The clamping module and pressing module fix and guide the pipe, keeping it level and preventing pipe deviation. This solves the problem of hole enlargement failure caused by pipe assembly deviation. The hole enlargement is driven by a motor, and the stroke of the extrusion head is controlled to avoid over-extrusion, ensuring the quality of the hole enlargement. The enlargement head is made of hard alloy material, and the head is designed with a tapered structure to adapt to the inner diameter of the pipe, ensuring a smooth and precise hole enlargement process. It is convenient for single-person operation, saves labor, improves work efficiency, and increases the pass rate.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
