Description

Technical Field

[0001] This utility model relates to the field of metal cutting technology, and in particular to a metal cutting circular saw. Background Technology

[0002] Metal cutting is a processing technique that uses physical or chemical methods to separate metal materials according to predetermined requirements. Its main purpose is to process raw metal materials into desired shapes and sizes to meet the manufacturing needs of different industrial sectors. Among metal cutting tools, the circular saw is a widely used and highly efficient piece of equipment in the metal processing field. It cuts metal materials using a high-speed rotating saw blade.

[0003] In existing technologies, the angle adjustment mechanism for metal parts cutting is rigid. During semi-automatic cutting operations, operators need to make repeated adjustments. Moreover, traditional cutting equipment lacks an effective fixing and adaptive adjustment mechanism for metal parts of different thicknesses and shapes. Therefore, we propose a metal cutting circular saw to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose a metal cutting circular saw.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

An electric push rod is fixedly connected inside the frame, and the outer wall of the output end of the electric push rod is fixedly connected to the outer wall of the T-shaped guide seat. The circular saw body is fixedly connected to the top of the T-shaped guide seat. A T-shaped shaft is fixedly connected to the top of the frame. A directional rod is rotatably fitted onto the outer wall of the T-shaped shaft. A sliding hole is formed on the outer wall of the directional rod, and a T-shaped threaded rod is slidably connected to the inner wall of the sliding hole. A locking cap is threaded onto the outer wall of the T-shaped threaded rod. Two guide bars are fixedly connected to the top of the frame, and a pressing assembly is provided on the top of the frame.

[0007] Preferably, the pressing assembly includes four dovetail blocks, and the outer walls of the two guide strips are provided with dovetail grooves. The inner walls of the two dovetail grooves are slidably connected to the outer walls of the four dovetail blocks respectively. The tops of the four dovetail blocks are fixedly connected with threaded connecting rods. The outer walls of the two threaded connecting rods are slidably fitted with the same pressing strip. The outer walls of the four threaded connecting rods are threaded with fastening caps. By setting the pressing assembly, metal parts of different thicknesses are limited to prevent them from moving during cutting.

[0008] Preferably, a groove is provided on the top of the frame.

[0020] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Depend on Figures 1-4 As shown, a metal cutting circular saw machine is disclosed, including a frame 1. Two guide rods 2 are fixedly connected inside the frame 1. The same T-shaped guide seat 3 is slidably sleeved on the outer wall of the two guide rods 2. The two guide rods 2 provide guidance for the movement of the T-shaped guide seat 3, ensuring that the T-shaped guide seat 3 can only move along a straight line, avoiding deviation or shaking during the movement, thereby ensuring the movement of the circular saw machine body 5.

[0022] An electric push rod 4 is fixedly connected inside the frame 1. The outer wall of the output end of the electric push rod 4 is fixedly connected to the outer wall of the T-shaped guide seat 3. The top of the T-shaped guide seat 3 is fixedly connected to the circular saw body 5. The electric push rod 4 drives the T-shaped guide seat 3 and the circular saw body 5 to move linearly, so as to realize the automatic movement of the saw blade to the cutting position of the metal part.

[0023] The top of the frame 1 is provided with a slide 6, which provides a channel for the movement of the saw blade, ensuring that the saw blade can move smoothly to the position where the metal part needs to be cut.

[0024] A T-shaped shaft 7 is fixedly connected to the top of the frame 1. An adjusting rod 8 is rotatably sleeved on the outer wall of the T-shaped shaft 7. The T-shaped shaft 7 serves as the fulcrum for the rotation of the adjusting rod 8, enabling the adjusting rod 8 to rotate stably around it. The bottom of the adjusting rod 8 is slidably connected to the top of the frame 1, and a sliding hole is provided on the outer wall of the adjusting rod 8.

[0025] The inner wall of the sliding hole is slidably connected to a T-shaped threaded rod 10, and the outer wall of the frame 1 is provided with an arc-shaped groove 9. The inner wall of the arc-shaped groove 9 is slidably connected to the outer wall of the T-shaped threaded rod 10. The arc-shaped groove 9 and the T-shaped threaded rod 10 cooperate to provide a trajectory restriction for the rotation of the directional rod 8, ensuring that the directional rod 8 rotates along a preset arc path when adjusting the angle, thus ensuring the accuracy of the angle adjustment.

[0026] The outer wall of the T-shaped threaded rod 10 is threaded with a locking cap 11. The screw head at the bottom of the T-shaped threaded rod 10 is provided with annular serrations. The annular serrations contact the top inner wall of the machine frame 1 to prevent slippage when the locking cap 11 rotates. Two guide bars 12 are fixedly connected to the top of the machine frame 1. The two guide bars 12 provide a track (dovetail groove) for the installation and sliding of the dovetail block 13, and play a guiding and limiting role in the movement of the dovetail block 13.

[0027] The locking cap 11, by rotating, causes its bottom to press against the top of the adjusting rod 8, which, together with the pressing of the top of the T-shaped threaded rod 10 against the inner wall of the frame 1, can quickly and firmly fix the adjusting rod 8.

[0028] The top of the frame 1 is provided with a pressing assembly, which includes four dovetail blocks 13. The outer walls of the two guide bars 12 are provided with dovetail grooves. The inner walls of the two dovetail grooves are slidably connected to the outer walls of the four dovetail blocks 13. The tops of the four dovetail blocks 13 are fixedly connected with threaded connecting rods 14. The outer walls of the two threaded connecting rods 14 are slidably fitted with the same pressing strip 15. The outer walls of the four threaded connecting rods 14 are threadedly fitted with fastening caps 16. The bottom of the fastening caps 16 is in contact with the top of the pressing strip 15.

[0029] The threaded connecting rod 14 provides mounting support for the lower pressure bar 15 and allows the lower pressure bar 15 to move up and down along it to accommodate metal parts of different thicknesses. Furthermore, by cooperating with the fastening cap 16, the lower pressure bar 15 can be fixed.

[0030] Working principle: When cutting metal, the metal part is placed on the top of the machine frame 1, located to the right of the directional rod 8 and attached to the outer wall of the directional rod 8. The tilt angle of the directional rod 8 can be selected according to the cutting angle. The directional rod 8 rotates around the T-shaped shaft 7, driving the T-shaped threaded rod 10 and the locking cap 11 to rotate along the arc groove 9. After the directional rod 8 is adjusted, the locking cap 11 is rotated so that its bottom is pressed against the top of the directional rod 8. The top of the T-shaped threaded rod 10 is pressed against the inner wall of the machine frame 1, thereby fixing the directional rod 8 to the top of the machine frame 1. The two lower pressure bars 15 are connected to the dovetail block 13 through the threaded connecting rod 14. The two pressure bars 15 are moved back and forth along the two dovetail grooves so that they are located at the top ends of the metal part and do not obstruct the position of the slide groove 6. The two pressure bars 15 can be moved up and down through the two sets of threaded connecting rods 14 to press down metal parts of different thicknesses. When fixing, simply rotate the four fastening caps 16 so that their bottoms press against the tops of the two pressure bars 15. The electric push rod 4 and the circular saw body 5 are rotated. The electric push rod 4 drives the T-shaped guide seat 3 to move linearly along the two guide rods 2, thereby driving the circular saw body 5 to move linearly. The saw blade moves along the slide groove 6 to the position of the metal part that needs to be cut.

[0031] It should be noted that, in actual use, an existing PLC controller can be added. The PLC controller is electrically connected to the electric push rod 4 and the circular saw body 5 to facilitate the control of the overall operation.

The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. Furthermore, the structure and principle of the components known to those skilled in the art can be learned by those skilled in the art through technical manuals or conventional experimental methods.
