Description

Technical Field

[0001] This utility model relates to the field of tool quenching technology, and in particular to a rotary heating quenching device. Background Technology

[0002] As we all know, cutting tools are important components of mechanical equipment. Depending on the items they cut, cutting tools come in a variety of structural styles, such as long, triangular, and round tools. The most common type is the round tool. In order to strengthen the blade, the blade needs to be hardened during manufacturing. This involves heating the blade and then immersing it in a quenching liquid.

[0003] Currently, the most common method for hardening cutting tools is to place the cutting edge on a heating coil and heat it through induction. The heating coil is designed to correspond to the shape and size of the cutting edge. However, due to installation tolerances and manufacturing processes, there can be temperature differences at different points when the heating coil heats a round cutting edge, resulting in uneven heating and inconsistent hardening effects. Utility Model Content

[0021] like Figures 1 to 5As shown, this embodiment provides a rotary heating quenching device, including a frame 1. The frame 1 is provided with a first slide rail 2 in a vertical direction. A first movable plate 3 that can reciprocate along the first slide rail 2 is mounted on the first slide rail 2. A mounting seat 4 is provided on the first movable plate 3. A rotating column 5 is connected to the mounting seat 4 via a bearing (not shown in the figure). A protrusion 6 is provided at the center of the top of the rotating column 5. At least one limiting protrusion 7 is provided on the side of the lower half of the rotating column 5. A horizontal plate 8 is provided below the rotating column 5 on the frame 1. A mounting hole 9 is provided on the horizontal plate 8. A first sprocket 10 is mounted in the mounting hole 9 via a bearing. The first sprocket 10 has a mating slot 11 in the middle that corresponds to the lower half of the rotating column 5. The lower half of the rotating column 5 is inserted into the mating slot 11, so that the rotating column 5... The rotating column 5 can rotate together with the first sprocket 10. A feeding trough 12 is provided on the frame 1, and a slotted opening 13 is provided at the bottom of the feeding trough 12. One end of the feeding trough 12 is positioned above the rotating column 5, and the diameter of the rotating column 5 is smaller than the width of the slotted opening 13. A second slide rail 14 is provided on the frame 1 at the feeding trough 12. A second movable plate 15, which can reciprocate along the second slide rail 14, is mounted on the second slide rail 14. A push rod 16 is provided on the second movable plate 15, and the push rod 16 passes through the slotted opening 13. A heating coil 17 for heating the tool 100 is provided on the frame 1 directly above the rotating column 5 and above the feeding trough 12. (To avoid the mounting components of the heating coil 17 and the frame 1 obscuring other components, the mounting components of the heating coil 17 are hidden, hence the attached diagram.) Figure 1 (The heating coil 17 shown is the suspended style). The frame 1 is equipped with a first electric push rod 18, a second electric push rod 19, and a rotary motor 20. The push rod of the first electric push rod 18 is connected to the first movable plate 3 and pushes the first movable plate 3 to slide along the first guide rail 2. The push rod of the second electric push rod 19 is connected to the second movable plate 15 and pushes the second movable plate 15 to slide along the second guide rail 14. The rotating head of the rotary motor 20 is equipped with a second sprocket 21, and the second sprocket 21 is connected to the first sprocket 10 by a chain 22.

[0022] This embodiment mainly uses a rotating column 5 that can rise and rotate as a base to support the cutting tool 100, so that the cutting tool 100 can rotate during heating, allowing the cutting edge to be heated evenly, thereby ensuring the effectiveness of the cutting tool quenching.

[0023] In operation, a cutting tool 100 is placed horizontally into the feeding trough 12. Then, the second electric push rod 19 moves the second movable plate 15 towards the rotating column 5, and the push rod 16 moves the cutting tool 100 towards the rotating column 5 as well. After the cutting tool 100 moves from one end of the feeding trough 12 to the other, the first electric push rod 18 also moves the first movable plate 3 upwards, simultaneously moving the rotating column 5 upwards. During the upward movement of the rotating column 5, the protrusion 6 at the top of the rotating column 5 first inserts into the mounting hole 101 of the cutting tool 100. The top surface of the rotating column 5 supports the bottom surface of the cutting tool 100. As the rotating column 5 continues to move upward, it reaches the heating coil 17. The lower half of the rotating column 5 moves up and down within the insertion port 11 of the first sprocket 10. The rotating motor 20 then operates, synchronously driving the first sprocket 10 to rotate via the second sprocket 21 and the chain 22. After the first sprocket 10 rotates, there are limiting protrusions 7 between the rotating column 5 and the first sprocket 10. The limiting protrusions 7 can be one or more; in this embodiment, six are designed. With this design, the rotating column 5 and the first sprocket 10 will rotate together, thereby driving the cutter 100 to rotate simultaneously. The cutter 100 can rotate while being heated, achieving the design requirements. After heating is complete, rotation stops, the first electric push rod 18 retracts, the rotating column 5 descends, and the tool 100 returns to the feeding trough 12. Then, under the action of the second electric push rod 19, the push rod 16 pushes the tool 100 out of the feeding trough 12 (after being pushed out, it falls directly into the quenching liquid). Finally, under the action of the second electric push rod 19, the second movable plate 15 and the push rod 16 return to their initial positions, waiting for the next tool 100.

[0024] Furthermore, to facilitate the automatic individual feeding of the cutting tools 100, a storage bin 200 is installed above the feeding trough 12 on the frame 1 in this embodiment. The storage bin 200 includes an inclined base plate 201, which is mounted on the frame 1. The base plate 201 is provided with a discharge trough 202 for stacking and storing the cutting tools 100. The discharge trough 202 is perpendicular to the base plate 201. A discharge gap is provided between the bottom of the discharge trough 202 and the base plate 201, allowing only a single cutting tool 100 to pass through. A third electric push rod 203 is provided on the base plate 201. The push rod of the third electric push rod 203 is connected to a push plate 204. The push plate is attached to the base plate 201 and can be inserted into the discharge gap. During operation, multiple cutters 100 are stacked one by one in the discharge trough 202. Each time the third electric push rod 203 is pushed, the push plate 204 pushes the bottom cutter 100 out of the discharge gap. After the third electric push rod 203 retracts, another cutter 100 will automatically fall into the discharge gap. Due to the gravity of the cutter 100, when there are other cutters above the cutter 100, the cutter 10 will not automatically discharge. Therefore, the push plate 204 needs to push the discharge one by one.

[0025] Furthermore, in order to enable the pusher to play a positioning role and prevent the tool from shifting during the pusher process, the top of the pusher plate 204 in this embodiment is provided with a groove 205 that can accommodate a single tool 100. The groove 205 is used to connect the tool 100 and prevent it from shifting during the pusher process.

[0026] Furthermore, to prevent the cutter 100 from automatically discharging material under vibration or other conditions when not pushing material, a crossbeam 206 is provided at the outlet of the discharge gap on the base plate 201 in this embodiment. A cylinder 207 is installed on the crossbeam 206, and the push head of the cylinder 207 is provided with a stop block 208. The stop block 208 is placed at the outlet of the discharge gap, so that when not discharging material, the stop block 208 blocks the discharge gap, and the cutter 100 cannot be discharged.

[0027] Furthermore, it should be noted that the quenched cutting tool 100 is mounted on the equipment, so the mounting hole 101 is generally square. In order to facilitate the insertion of the protrusion 7 into the mounting hole 101, the protrusion 101 in this embodiment is shaped like a frustum of a cone, with the top of the frustum as the tip. This can play a guiding role during insertion. As for driving the cutting tool 100 to rotate, it mainly relies on the weight of the cutting tool 100 itself to adhere to the rotating column 5. The main function of the protrusion 7 is to prevent the cutting tool 100 from deviating during rotation and to play a limiting role.

[0028] Furthermore, because assembly space is required when assembling the chain 22 and sprocket, the chain 22 is generally designed to be longer for installation. However, if the chain 22 is too long, it is prone to falling off. Therefore, to straighten the chain 22, it also includes a mounting block 23. The mounting block 23 is provided with a strip-shaped hole 24, and the cross plate 8 is provided with a threaded hole. A bolt is inserted into the strip-shaped hole 24 of the mounting block 23 and locked into the threaded hole. The mounting block 23 is connected to a third sprocket 25 through a bearing. The third sprocket 25 is connected to the chain 22. By moving between the strip-shaped holes 24, the mounting block 23 is positioned in the most suitable position. After the bolt is locked in, the third sprocket 25 can be used as a force to press against the chain 22, thereby straightening the chain 22.

[0029] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
