Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing equipment, specifically a feeding device for cold drawing of steel pipes. Background Technology

[0002] Cold drawing of steel pipes, also known as cold drawing of steel pipes, is an important steel pipe manufacturing process. Cold drawn steel pipes are made by piercing steel ingots or solid tube blanks to form rough tubes, and then cold drawing them. Cold drawn steel pipes are round, square or rectangular steel materials with hollow cross sections and no seams around the perimeter. They have no seams on the surface, high dimensional accuracy and good surface finish.

[0003] When steel pipes are cold drawn, the stacked raw material pipes are usually unloaded at intervals onto a single-chain or double-chain cold drawing machine with a capacity of 0.5 to 100 tons for cold drawing. When unloading the stacked steel pipes, a robotic arm adapted to the corresponding set program is generally used.

[0004] The robotic arm is precisely controlled by a set program to grab the stacked steel pipes and feed them to the inlet of the cold drawing machine. This feeding method is flexible and agile, and does not require manual secondary feeding, so it is convenient to use and has high feeding efficiency. However, there are also obvious problems and drawbacks. For example, the cost of the robotic arm to adapt the setting program is high, which leads to a high installation cost of the entire cold drawing steel pipe production line, making it difficult for some small production enterprises to purchase and use.

[0005] In view of the problems mentioned above in the background art, the present invention aims to provide a feeding device for cold drawing of steel pipes. Utility Model Content

[0006] The purpose of this invention is to provide a feeding device for cold drawing of steel pipes to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A feeding device for cold drawing of steel pipes, the feeding device comprising:

[0009] The front material rack, unloading platform, support, and rear material rack are arranged in a linear front-to-back sequence. The front material rack, unloading platform, support, and rear material rack are all arranged at an angle, and the angles are consistent.

[0010] A bottom inclined plate is installed at the position where the lower end of the front material rack contacts the lower end of the material unloading platform; the material unloading platform is fixedly installed on one side of the upper end of the bracket, and a guide frame is provided at the position where the other side of the upper end of the bracket contacts the rear material rack. The guide frame is L-shaped; at the same time, an arc groove is formed at the upper end of the bracket.

[0011] Pushing components are installed inside the bottom inclined plate, inside the unloading platform, and at the arc-shaped groove formed at the upper end of the support to control the lifting of the steel pipe and achieve regular, intermittent unloading operations.

[0012] As a further embodiment of this utility model: the pushing component includes a movable block, which is simultaneously slidably installed inside the bottom inclined plate, inside the unloading platform, and inside the arc-shaped groove formed at the upper end of the bracket. A slot is formed on one side of the upper end of the movable block, and an arc-shaped unloading surface is formed on the other side of the upper end of the movable block.

[0013] As a further embodiment of this utility model: the lower middle of the movable block is connected to a pneumatic telescopic rod, the lower end of the pneumatic telescopic rod is installed inside the output end of the cylinder, and the cylinder is located on one side of the bracket.

[0014] As a further embodiment of this utility model: the lower end of the bracket is mounted on the base, the base and the bracket form an L shape, and a cylinder is mounted on the other side of the upper end of the base.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] Compared with the current method of using a robotic arm to cut steel pipes, the aforementioned unloading device for cold drawing steel pipe production has the following advantages:

[0017] It consists of a front material rack, a feeding platform, a support, and a rear material rack arranged in sequence. The front material rack, feeding platform, support, and rear material rack are arranged in a linear front-to-back pattern. The front material rack, feeding platform, and rear material rack are all arranged at an angle, and the angles are consistent.

[0018] Next, pushing components are installed inside the bottom inclined plate, inside the unloading platform, and at the arc-shaped groove formed at the upper end of the support. The steel pipe can be lifted by the operation of the pushing components. Then, the steel pipe can roll along the unloading platform, the support, and the rear material rack by the acceleration generated by its own gravity, thereby realizing the automatic unloading operation of the steel pipe.

[0019] The entire cold-drawing steel pipe production unloading device has a simple structure design, does not require setting corresponding programs for control, and can automatically unload stacked steel pipes while performing repetitive and simple actions. Moreover, the cost is also low, and it can be widely used in production lines. Attached Figure Description

[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Example

[0026] Please see Figure 1 and Figure 2 The steel pipe cold drawing production unloading device provided in this embodiment of the utility model includes:

[0027] The front material rack 2, the unloading platform 5, the support 9, and the rear material rack 12 are arranged in a linear front-to-back sequence. The front material rack 2, the unloading platform 5, the support 9, and the rear material rack 12 are all arranged at an angle, and the angles are consistent.

[0028] Among them, a bottom inclined plate 3 is installed at the position where the lower end of the front material rack 2 contacts the lower end of the material unloading platform 5; the material unloading platform 5 is fixed on the upper end of the bracket 9, and a guide rack 11 is provided at the position where the upper end of the bracket 9 contacts the rear material rack 12. The guide rack 11 is L-shaped; at the same time, an arc groove 10 is formed at the upper end of the bracket 9.

[0029] Pushing components are installed inside the bottom inclined plate 3, inside the unloading platform 5, and at the position of the arc-shaped groove 10 formed at the upper end of the support 9. The pushing components are used to control the steel pipe to lift and realize regular intermittent unloading operations.

[0030] In an embodiment of this utility model, when the steel pipe cold drawing production unloading device is used, for example, after the steel pipe is cold drawn, it flows into the interior of the front material rack 2. Since the front material rack 2 is installed at an angle, the steel pipe inside the front material rack 2 can be rolled and displaced to the position where one side of the front material rack 2 is connected to the side of the unloading platform 5 by the acceleration generated by its own gravity, that is, temporarily stored on the upper surface of the bottom inclined plate 3.

[0031] Next, the pushing component is started, and the pushing component operates to lift the steel pipe at the bottom inclined plate 3 position. After being lifted to the upper end of the unloading platform 5, the lifted steel pipe falls to the upper surface of the unloading platform 5. At this time, the pushing component stops operating, and the steel pipe stops on the upper surface of the unloading platform 5. Then the pushing component operates again to descend. The steel pipe located on the upper surface of the unloading platform 5 slides and moves along the upper end of the support 9 to the guide frame 11 position under the action of gravity. Then, at the guide frame 11 position, it falls to the upper surface of the rear material rack 12 under its own gravity and continues to fall and move along the surface of the rear material rack 12.

[0032] By repeatedly pushing the component, the steel pipes after the cold drawing process can be automatically unloaded.

[0033] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the pushing component includes a movable block 4, which is simultaneously slidably installed inside the bottom inclined plate 3, inside the unloading platform 5, and inside the arc-shaped groove 10 formed at the upper end of the bracket 9. A slot 13 is formed on one side of the upper end of the movable block 4, and an arc-shaped unloading surface 14 is formed on the other side of the upper end of the movable block 4.

[0034] For example, when the movable block 4 is lifted along the inside of the bottom inclined plate 3, the steel pipe 1 that is stuck at the lower end of the front material rack 2 and the lower side of the unloading platform 5 will be lifted. After being lifted to the upper side of the unloading platform 5, the movable block 4 is then lifted inside the unloading platform 5, and the unloading platform 5 is temporarily left on the upper surface of the unloading platform 5 through the formed slot 13.

[0035] Then the movable block 4 descends and moves. When the movable block 4 moves to the same horizontal plane as the lower end of the unloading platform 5, the steel pipe 1 located on the upper surface of the unloading platform 5 will roll down to the upper surface of the arc-shaped unloading surface 14 due to its own gravity. Then it will continue to roll and move along the upper surface of the arc-shaped unloading surface 14 to the position of the guide frame 11. Finally, it will roll down along the guide frame 11 into the upper surface of the rear material rack 12 to realize the unloading operation.

[0036] Specifically, the lower middle of the movable block 4 is connected to the pneumatic telescopic rod 6, the lower end of the pneumatic telescopic rod 6 is installed inside the output end of the cylinder 7, and the cylinder 7 is located on one side of the bracket 9;

[0037] In an embodiment of this utility model, when the movable block 4 is pushed to move up and down, the kinetic energy output by the start cylinder 7 drives the pneumatic telescopic rod 6 to extend and retract. When the pneumatic telescopic rod 6 extends and retracts, it can drive the movable block 4 installed at the upper end of the pneumatic telescopic rod 6 to move up and down, thereby realizing the lifting of the steel pipe 1 and the unloading operation at regular time intervals.

[0038] Please see Figure 1 and Figure 2 In one embodiment of the present invention, the lower end of the bracket 9 is mounted on the base 8, the base 8 and the bracket 9 form an L shape, and a cylinder 7 is mounted on the other side of the upper end of the base 8.

[0039] The base 8 is used to support both the cylinder 7 and the bracket 9, ensuring the stability of the unloading device for cold drawing of steel pipes when it is placed.

[0040] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
