Description

Technical Field

[0001] The utility model relates to the field of steel bar cutting and processing, in particular to a cutting and positioning mechanism for heat treatment of steel bars. Background Art

[0002] Steel bars generally refer to steel materials used in various industrial applications. They have a circular cross-section and are usually long strips of metal. Steel bars have a wide range of uses in the engineering field, and common applications include building structures, machinery manufacturing, automotive industry, shipbuilding, etc. They can have different strength, wear resistance, corrosion resistance and other characteristics as required.

[0003] When cutting steel bars, due to the high strength of the steel bars themselves, most of the time, they need to be heat treated to soften the internal structure at high temperature so that they can be cut by the cutting positioning mechanism.

[0004] When cutting steel bars, the existing cutting mechanism needs to use a positioning device to position and fix the steel bars. However, when positioning and fixing the steel bars, most of them use threaded tooling to fix the steel bars. When the number of steel bars is too large, the threaded rod needs to be repeatedly rotated to disassemble and fix the steel bars. The actual operation is time-consuming and labor-intensive. When cutting the steel bars, most of them are manually measured, and then the surface of the steel bars is marked and the position of the steel bars is adjusted for cutting. It is impossible to adjust the fixed position of the steel bars according to the cutting length of the steel bars during the cutting process, resulting in a decrease in cutting efficiency. Therefore, a cutting and positioning mechanism for heat treatment of steel bars is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1-Figure 3The utility model provides an embodiment: a cutting and positioning mechanism for heat treatment of steel bars, comprising a workbench 1, an electric slide rail 2 is arranged on the surface of the top of the workbench 1, the electric slide rail 2 is a prior art, a motor is arranged on the left side wall of the workbench 1, and the electric slide rail 2 can drive the fixed plate 71 to move horizontally on its surface through the drive of the motor, so that the steel bars fixed on the surface after heat treatment can be moved, so as to facilitate cutting thereof, a support frame 4 is fixedly connected to the right side of the top of the workbench 1, and an electric telescopic rod B8 is fixedly connected to the top of the outer wall of the support frame 4, and the workbench The surface on the right side of the top end of the electric telescopic rod B8 is provided with a scale line 3, which is a length scale value. The positioning component 7 is used to push the steel rod to move, so as to judge the length of the steel rod cut after passing through the support component 6 and cooperating with the scale line 3 to penetrate the steel rod after heat treatment. The bottom end of the outer wall of the electric telescopic rod B8 is provided with a cutting saw 5, and a motor is provided inside the cutting saw 5. The motor can drive the cutting saw 5 to rotate at a high speed, so as to cut the steel rod that has been heat treated in advance, and through the cooperation of the electric telescopic rod B8, the cutting saw 5 can be controlled to move up and down to fit with the steel rod.

[0031] Reference Figure 1-Figure 3 The inner wall of the electric slide rail 2 is provided with a positioning assembly 7, and a supporting assembly 6 is provided at the center of the top of the workbench 1. The positioning assembly 7 includes a fixed plate 71, and the bottom end of the outer wall of the fixed plate 71 is slidably connected to the inner wall of the electric slide rail 2. The electric slide rail 2 drives the fixed plate 71 to move the steel rod, so as to adjust the length of the steel rod passing through the cutting saw 5 to achieve a fixed length cutting of the steel rod. The surface of the fixed plate 71 is provided with four groups of guide grooves, and the clamping block 75 is slidably connected to the inner wall of the guide groove of the fixed plate 71. By providing the guide groove on the surface of the fixed plate 71, the four groups of clamping blocks 75 can move toward each other inside the guide groove, so as to clamp and fix the steel rod. The left inner wall of the fixed disk 71 is rotatably connected with a rotating block 72, and the outer wall of the rotating block 72 is rotatably connected with four groups of connecting blocks 73. The four groups of connecting blocks 73 are hinged with a hinged rod 74 at one end away from the rotating block 72. When the rotating block 72 rotates, it will drive the four groups of connecting blocks 73 to rotate, so as to pull the hinged rod 74 and the clamping block 75 to move toward each other inside the fixed disk 71 through the connecting block 73, so as to clamp and position the steel rod. The hinged rod 74 is hinged with a clamping block 75 at one end away from the connecting block 73.

[0032] Reference Figure 2-Figure 3The curved surface of the clamping block 75 is fixedly connected with a rubber column 76. The rubber column 76 is a prior art, so that after the steel rod is clamped, the rubber column 76 can be deformed to always fit the steel rod, thereby increasing the contact area between the rubber column 76 and the steel rod, making the steel rod more stable. At the same time, it also has an additional elastic contact effect on the intermittent limit of the rotating block 72. The inner wall of the rotating block 72 is elastically connected with an insert block 78 through a limit spring 77. One end of the limit spring 77 is fixedly connected to the inner wall of the rotating block 72. The other end of the positioning spring 77 is fixedly connected to the right outer wall of the plug block 78. The function of the limiting spring 77 is to automatically reset the position of the plug block 78 after it is moved. The plug block 78 is slidably connected to the inner wall of the rotating block 72. The inner wall of the fixed disk 71 has multiple sets of through holes. The plug block 78 is plugged into the inner wall of the through hole of the fixed disk 71. The plug-in between the two drives the rotating block 72 to drive the connecting block 73 and the hinge rod 74 to pull the clamping block 75 to fix the position of the steel rod after it is fixed, thereby preventing the steel rod from shaking during the cutting process.

[0033] Reference Figure 1 and Figure 4 The support assembly 6 includes a fixed ring 61, and the bottom end of the outer wall of the fixed ring 61 is fixedly connected to an electric telescopic rod A62, and the electric telescopic rod A62 is fixedly connected to the top of the outer wall of the workbench 1. By setting the electric telescopic rod A62, the fixed ring 61 can be pushed up and down, so as to adjust the support according to the thickness of different steel bars.

[0034] Working principle: first, pass the heat-treated steel rod through the interior of the fixing ring 61, and then pull the plug block 78 out of the through hole of the current position of the fixing disk 71. At this time, the rotating block 72 on the left inner wall of the fixing disk 71 can be rotated to drive the connecting block 73 to rotate, so that the hinge rod 74 will pull the clamping block 75 to move toward each other in the guide groove of the fixing disk 71, clamping and fixing the steel rod. The rubber column 76 on the arc surface of the clamping block 75 increases the contact area with the steel rod, making the steel rod fixation more stable. When adjusted to the appropriate position, the limit spring 77 in the rotating block 72 automatically resets the position of the plug block 78 after it is moved, and the plug block 78 is plugged into the through hole of the fixing disk 71 to fix the clamping position of the steel rod and prevent the steel rod from shaking during cutting.

[0035] At this time, the electric telescopic rod A62 can be started to allow its output shaft to lift the fixed ring 61 upward, thereby supporting the other end of the steel rod. At this time, the electric slide rail 2 can be driven by the motor on the left side wall of the workbench 1 to make the fixed plate 71 move horizontally on its surface, driving the steel rod to move, and the length of the steel rod passing through the support assembly 6 can be judged in conjunction with the scale line 3 to achieve fixed-length cutting. The electric telescopic rod B8 at the top of the outer wall of the support frame 4 controls the cutting saw 5 to move up and down to fit the steel rod, and the motor inside the cutting saw 5 drives it to rotate at high speed to cut the steel rod.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
