Description

Technical Field

[0001] This utility model relates to the field of mechanical manufacturing technology, specifically to a stainless steel water pipe stretching device. Background Technology

[0002] Stainless steel water pipes are pipes made of stainless steel and are mainly used to transport water or other liquids. Their main components include alloying elements such as iron, chromium, and nickel, with a chromium content of no less than 10.5%, which is crucial for their corrosion resistance. Due to their corrosion resistance, non-polluting properties, and long service life, stainless steel water pipes are widely used in environments requiring long-term durability and pollution-free operation, such as food processing plants, medical facilities, and chemical plants.

[0003] The prior art disclosure number CN214133366U discloses a steel pipe stretching device, including a base and a support column. Two movable blocks are provided on the upper end of the base, and a driving assembly is provided on the side end of the base. Another movable block is fixedly connected to the base. A clamping seat is fixedly connected to the upper end of each movable block. A through hole is provided in the middle of the clamping seat, and two clamping blocks are placed inside the through hole. Several protrusions are provided at the lower end of each clamping block. A driving assembly is provided inside the clamping seat. A heating seat is fixedly connected to the upper end of the base, and an annular heating block is provided inside the heating seat. A cooling box is fixedly connected to the upper end of the heating seat. The cooling box contains cooling water and a circulating pump. A cooling cylinder is provided on the heating seat. Both ends of the cooling box are connected to the cooling cylinder through circulating pipes. The circulating pump in the cooling box circulates the cooling water in the cooling box through the circulating pipes and the cooling cylinder. The cooling cylinder cools the stretched steel pipe, thereby achieving rapid cooling of the steel pipe and facilitating rapid processing in the next step.

[0004] With the above configuration, the existing stretching device circulates cooling water in the cooling tank through a circulating pump via a circulation pipe and a cooling cylinder. The cooling cylinder cools the stretched steel pipe, achieving rapid cooling and facilitating further processing. Components such as threaded columns, rotating columns, fixed blocks, moving columns, and rotating rods are used to clamp the steel pipe, providing convenient, quick, and stable clamping. Components such as motors, lead screws, sliders, and vertical columns move the clamping seats on the base, achieving stable and easily controllable stretching length. However, the existing stretching device has the following drawbacks during operation:

[0005] When using the existing stretching device, the steel pipe needs to be passed through the through hole on the clamping seat and through the heating seat. Then, by turning the four threaded pins, the clamping block moves downward to clamp the steel pipe. During the clamping process, the four threaded pins need to be turned simultaneously and must rotate synchronously. Otherwise, one threaded pin will be blocked by another threaded pin, causing the clamping block to be unable to move and thus unable to clamp the steel pipe. Turning the threaded pins is very troublesome, and it is difficult to rotate the threaded pins at the same angle at the same time, making it very troublesome to clamp the steel pipe. Utility Model Content

[0006] The present invention aims to provide a stainless steel water pipe stretching device, which is mainly used to solve the technical problem that it is very troublesome to simultaneously tighten four threaded pins to clamp the steel pipe, and the steel pipe cannot be clamped if they are not tightened at the same time.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A stainless steel water pipe stretching device includes a movable block and a clamping seat. The clamping seat is fixed on the upper surface of the movable block. A through hole is provided on one side of the clamping seat. A first movable cavity, a second movable cavity, and a third movable cavity are symmetrically provided inside the clamping seat. The first movable cavity and the third movable cavity are connected to the second movable cavity. Through grooves are symmetrically provided at the upper and lower ends of the clamping seat. The through grooves are connected to the through hole. A clamping component is provided on the inner wall of the through groove.

[0009] The working principle and beneficial effects of this utility model:

[0010] 1. Working principle: When it is necessary to clamp the water pipe, first place the water pipe through the through hole, and then turn the rotating block to make the rotating block drive the second bevel gear to rotate, the second bevel gear drive the first bevel gear to rotate, the first bevel gear drive the rotating rod to rotate, the rotating rod drive the second gear to rotate, the second gear drive the first gear to rotate, and the threaded rod can be lowered so that the clamping plate clamps the water pipe, thus completing the operation.

[0011] 2. Beneficial effects:

[0012] Existing technology uses a circulating pump in a cooling tank to circulate cooling water through a circulating pipe and a cooling cylinder. The cooling cylinder cools the stretched steel pipe, achieving rapid cooling for subsequent processing. Clamping blocks use threaded columns, rotating columns, fixed blocks, moving columns, and rotating rods to hold the steel pipe, providing convenient, quick, and stable clamping. The movement of the clamping seat on the base, achieved through a motor, lead screw, slider, and vertical column, allows for stable and controlled stretching of the steel pipe. However, existing stretching devices require the steel pipe to first pass through a through hole in the clamping seat and through the heating base. Then, by turning four threaded columns, the clamping blocks move downwards to clamp the steel pipe. During clamping, all four threads need to be turned simultaneously. The traditional method involves using threaded posts that must rotate synchronously. Otherwise, one post will be blocked by another, preventing the clamping block from moving and thus hindering the clamping of the steel pipe. Tightening the threaded posts is cumbersome, and it's difficult to rotate them simultaneously at the same angle, making pipe clamping extremely challenging. This solution addresses this by using a first gear, a second gear, a threaded rod, a clamping plate, a first bevel gear, a second bevel gear, and a rotating block. Rotating the rotating block drives the second and first bevel gears to rotate, which in turn drives the second and first gears to rotate via the rotating rod. This causes the threaded rod to connect with the first gear, which in turn drives the clamping plate to clamp the water pipe, resulting in a more secure clamping. Tightening a single rotating block is also very convenient, preventing the clamping plate from failing to lower or raise, thus improving the technical effectiveness of pipe clamping.

[0013] Preferably, the clamping assembly includes a first gear, which is rotatably connected to the inner wall of the first movable cavity. A threaded rod is slidably connected to the inner wall of the slot, passing through and threadedly connected to the first gear. A clamping plate is rotatably connected to one end of the threaded rod inside the through hole. A linkage assembly is installed on the inner wall of the second movable cavity. By setting the clamping assembly, the water pipe can be firmly clamped, preventing the water pipe from moving.

[0014] Preferably, the linkage assembly includes a second gear, which is rotatably connected to the inner wall of the second movable cavity and meshes with the first gear. A rotating rod is fixedly connected to one side of the second gear, and the rotating rod extends into the third movable cavity where a first bevel gear is fixedly connected. A second bevel gear is rotatably connected inside the third movable cavity, and the first bevel gear meshes with the second bevel gear. A rotating shaft is fixedly connected to one end of the second bevel gear, and the rotating shaft passes through the clamping seat and is rotatably connected to it. By setting up the linkage assembly, the upper and lower clamping plates can be driven to clamp the water pipe, and the fixing method is very convenient and very stable.

[0015] Preferably, the inner wall of the through hole is provided with symmetrical guide grooves, and a guide rod is slidably connected to the inner wall of the guide groove. The guide rod is fixedly connected to the outer wall of the clamping plate. By setting the guide rod and guide groove, the clamping plate can be prevented from rotating along with the threaded rod when it rotates, making the clamping plate more stable.

[0016] Preferably, the upper surface of the movable block has a storage groove, and one of the threaded rods is inserted into the storage groove. By providing the storage groove, it is convenient for one of the threaded rods to move.

[0017] Preferably, a rotating block is fixed to the end of the rotating shaft away from the second bevel gear, and a cross groove is formed on one side of the rotating block. By setting the rotating block, the second bevel gear can be rotated easily. Attached Figure Description
