Description

Technical Field

[0001] This utility model relates to the field of steel pipe elbow processing technology, and more specifically, to a cutting device for processing steel pipe elbows. Background Technology

[0002] In the construction site of thin-walled steel pipes, the connecting channels between steel pipes are connected by straight pipes and elbows. The elbows are basically 90° or 45° elbows. In order to meet different construction requirements, it is often necessary to use elbows with irregular angles to achieve the connection, which requires the use of cutting devices to cut the bends.

[0003] Based on the above, the inventors have discovered that: currently, existing cutting devices typically place the elbow on a mold for cutting. This method can only cut a single type of elbow and cannot be applied to bends of different specifications, resulting in low applicability. Therefore, in view of this, the inventors have researched and improved the existing structure to provide a cutting device for processing steel pipe elbows, aiming to achieve a more practical purpose.

[0015] 3. Beneficial effects

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] (1) In this scheme, cylinder one and mounting base are bolted to the top of the base plate. The elbow to be cut is placed between elbow clamp one and elbow clamp two. At this time, cylinder two drives elbow clamp one on the positioning plate to hold the elbow and fix it. Then, cylinder one drives the fixed axis to move upward, and the two sets of connecting arms will move in the opposite direction to the fixed axis. This allows the motor to drive the cutting blade to cut the elbow. The distance of the elbow clamp can be adjusted according to the different specifications of the elbow. It has high applicability and is convenient to use.

[0018] (2) In this solution, two sets of barriers are symmetrically placed on both sides of the mounting base. When the elbow is cut, the generated debris is blocked by the barriers and falls onto the base plate. Then the debris will fall into the collection box through the vent for collection, which can effectively prevent debris from flying everywhere and causing injury to the operator.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example:

[0027] Please see Figure 1-4A cutting device for processing steel pipe elbows includes a base plate 1. A cylinder 2 and a mounting base 6 are bolted to the top of the base plate 1 from left to right. The cylinder 2 drives a motor 3 and a cutting blade 4 for angle adjustment. The motor 3 is mounted on the top of the cylinder 2, and the cutting blade 4 is mounted on the output end of the motor 3. The motor 3 and the cutting blade 4 are used to cut the elbow. A baffle 5 is fixedly connected to the upper part of the base plate 1 to prevent debris from flying everywhere during elbow cutting. A vent 9 is provided on the inner side of the base plate 1. A fixing plate 7 and a fixing plate 18 are fixedly connected to the upper sides of the mounting base 6. A cylinder 8 is mounted on one side of the fixing plate 7, and a positioning plate 19 is fixedly connected to the output end of the cylinder 8. A bend is bolted to one side of the positioning plate 19 and the fixing plate 18. The head clamp 20 and the elbow clamp 21, the positioning plate 19 and the fixing plate 28 are used to install the elbow clamp 20 and the elbow clamp 21 respectively. The bottom of the base plate 1 is provided with a collection box 10, which is used to collect the debris generated during cutting. The cylinder 2 is provided with an installation head 11 on one side. The upper part of the installation head 11 is connected to the connecting frame 12 through a movable rod. The inner side of the connecting frame 12 is threaded with a fastening rod 13. The fastening rod 13 is used to fix the connecting head to the top of the fastening rod 13. A fixing shaft 16 is installed on one side of the connecting head. The fixing shaft 16 is used to cooperate with the cylinder to drive the motor 3 and the cutting blade 4 for angle adjustment. A connecting arm 14 is installed on the inner side of the connecting head. An installation sleeve 15 is sleeved on the outer side of the fixing shaft 16. A fixing sleeve 17 is fixedly connected to one side of the connecting arm 14.

[0028] See Figure 1 and Figure 3 The output end of cylinder 2 is equipped with a connector, which is sleeved on the outside of fixed shaft 16. By setting cylinder 2, it can cooperate with fixed shaft 16 to drive motor 3 and cutting blade 4 to adjust the angle.

[0029] See Figure 1 and Figure 2 The output end of motor 3 is equipped with a worm gear, one side of which is meshed with a worm wheel. A connecting shaft is installed on the inner side of the worm wheel, and one end of the connecting shaft is connected to the cutting blade 4. By setting up motor 3 and cutting blade 4, elbows can be cut.

[0030] See Figure 1 Two sets of enclosure 5 are symmetrically arranged on both sides above the base plate 1. By setting enclosure 5, the debris generated during the bending cutting can be prevented from flying everywhere.

[0031] See Figure 2 and Figure 4 The elbow clamp 1 20 and elbow clamp 21 are made of rubber material. By setting elbow clamp 1 20 and elbow clamp 21, the elbow can be clamped.

[0032] See Figure 2 and Figure 4There are two sets of elbow clamp 1 20 and elbow clamp 21. The two sets of elbow clamp 1 20 and elbow clamp 21 are staggered. By setting elbow clamp 1 20 and elbow clamp 21 in a staggered distribution, the elbow can be clamped and fixed.

[0033] See Figure 1 and Figure 3 A movable shaft is installed on the inner side of the fixed sleeve 17. The two ends of the movable shaft are connected to the connecting arm 14 respectively. By setting the fixed sleeve 17 and the fixed shaft 16, the two sets of connecting arms 14 can be fixed.

[0034] In use: First, bolt cylinder 2 and mounting base 6 to the top of base plate 1. Place the elbow to be cut between elbow clamp 20 and elbow clamp 21. At this time, cylinder 2 drives elbow clamp 20 on positioning plate 19 to hold the elbow in place. Then, cylinder 2 drives the fixing shaft 16 to move upward, and the two sets of connecting arms 14 will move in the opposite direction with the fixing shaft 16. This allows motor 3 to drive cutting blade 4 to cut the elbow. Two sets of guardrails 5 are symmetrically arranged on both sides of mounting base 6. When cutting the elbow, the debris generated is blocked by the guardrails 5 and falls onto base plate 1. Then, the debris will fall into collection box 10 through the drain 9 for collection. This effectively prevents debris from flying everywhere and causing injury to the operator. The distance of elbow clamps can be adjusted according to the different specifications of elbows, making it highly applicable and convenient to use.
