Description

Technical Field

[0001] This utility model relates to the field of cutting equipment technology, specifically a steel pipe cutting device for construction. Background Technology

[0002] With the development of the construction industry, there are increasingly more methods for processing building materials. Steel pipes are the most widely used building material. In the use of steel pipes, they usually need to be cut to the required length. This requires cutting equipment. Most existing cutting equipment uses a motor to cut the steel pipe onto a cutting disc. However, the cutting teeth are prone to deformation after prolonged cutting, affecting cutting efficiency. Workers need to grind the cutting teeth to improve efficiency, but manual grinding is tedious. Therefore, we propose a steel pipe cutting device for construction. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] Please see Figure 1-2This utility model provides a technical solution: a steel pipe cutting device for construction, including a shell 1. A rotating shaft is connected to the inner right side wall of the shell 1 via a bearing. A cutting disc 2 is sleeved on the outer wall of the rotating shaft. Cutting teeth are evenly distributed on the outer side wall of the cutting disc 2. A motor 4 is located on the left side wall of the shell 1, and the output end of the motor 4 is connected to one end of the rotating shaft. A handle 3 is located on the right side wall of the shell 1, and an anti-slip sleeve is provided on the outer side wall of the handle 3 to prevent slippage for workers. A grinding assembly 5 is located on the top of the shell 1. The grinding assembly 5 includes a fixed box 51 on the top of the shell 1, and a bidirectional lead screw 56 is located inside the fixed box 51. Fixed plates are sleeved on both sides of the outer wall of the bidirectional lead screw 56, and the tops of both sets of fixed plates are connected to the top of the inner wall of the fixed box 51. Under the action of the fixed plates, the bidirectional lead screw 56 rotates more stably. Movable rods 57 are fitted on both sides of the outer wall of the screw 56. One end of each set of movable rods 57 passes through the left and right side walls of the fixed box 51 and the left and right side walls of the outer shell 1, respectively, and connects to the grinding block 50 provided inside the outer shell 1. A guide groove is provided at the bottom of the fixed box 51. Guide blocks matching the guide groove are provided on the outer walls of the two sets of movable rods 57. Under the action of the guide groove and the guide block, the movable rods 57 move more stably on the outer wall of the double-acting screw 56. The movable rods 57 are U-shaped. The grinding block 50 is made of diamond. A driven bevel gear 54 is fitted on the outer wall of the double-acting screw 56. An active bevel gear 53 meshes with the driven bevel gear 54 inside the fixed box 51. A rotating rod 52 is provided on the top of the active bevel gear 53. One end of the rotating rod 52 passes through the top of the fixed box 51 and connects to the adjustment knob 55 provided outside.

[0016] Working principle: The outer casing 1 is hinged and installed on the cutting table (as is the case with existing technology). The steel pipe is placed on the cutting table, and the operator holds the handle 3 to rotate the outer casing 1. The motor 4 drives the cutting disc 2 to rotate, and the cutting disc 2 can cut the steel pipe. When it is necessary to grind the cutting teeth of the cutting disc 2, the operator rotates the adjustment knob 55 to rotate the rotating rod 57. The rotating rod 57 drives the driving bevel gear 53 to rotate, the driving bevel gear 53 drives the driven bevel gear 54 to rotate, and the driven bevel gear 54 drives the double-acting screw 56 to rotate. Under the action of the guide groove and the guide block, the two sets of moving rods 57 move relative to each other on the outer wall of the double-acting screw 56. The moving rods 57 drive the grinding block 50 to move. The grinding block 50 contacts the cutting teeth of the cutting disc 2. Then the motor 4 drives the cutting disc 2 to rotate, and the grinding block 50 can grind the cutting teeth.
