Description

Technical Field

[0001] This invention relates to a lawnmower production equipment, specifically a high-frequency heat treatment equipment for garden knives. Background Technology

[0002] High-frequency induction heating heat treatment is a key process in the machinery manufacturing industry for improving the surface hardness, wear resistance, and fatigue strength of metal parts. This process offers advantages such as rapid heating, high efficiency, and ease of localized heating, and is widely used in the production of various hardware tools.

[0003] For lawnmower blades with a straight blade structure, both sides are sharpened, requiring high-frequency induction heating of the blade edges before quenching. Due to the complexity of the manufacturing process, manual positioning and heating are still widely used, resulting in the following significant drawbacks: 1. Poor product quality consistency: Manual operation makes it difficult to ensure that the position, angle, and dwell time of each blade in the induction coil are completely consistent. Small deviations in position and time can lead to displacement of the heating area, uneven depth of the hardened layer, and even overheating burns or insufficient heating.

[0004] 2. Low cooling synchronization: The time interval (transfer time) between manual material feeding and quenching medium is affected by the worker's reaction speed, resulting in inconsistent cooling start temperature, which directly affects the metallographic structure and final hardness, causing large quality dispersion within product batches and a high scrap rate.

[0005] 3. Low production efficiency and obvious capacity bottlenecks: The pace of manual loading and unloading is much slower than the heating speed of high-frequency equipment, causing the equipment to be in a "waiting" state frequently, resulting in low equipment utilization. Furthermore, due to the physical strength and working hours of the workers, it is impossible to achieve 24-hour continuous high-intensity operation, making it difficult to meet the needs of large-scale mass production.

[0006] 4. High labor intensity and high occupational health and safety risks: High-frequency heat treatment sites are usually accompanied by high-temperature radiation, noise, and quenching oil mist / steam. Workers are prone to fatigue due to long-term repetitive heavy handling and positioning operations in high-temperature environments, which not only affects efficiency but also increases the risk of safety accidents such as burns and mechanical injuries.

[0007] In order to overcome the problems of unstable quality, low efficiency and safety hazards caused by manual operation, it is urgent to upgrade the traditional manual high-frequency heat treatment process to a fully automated loading, unloading and heating quenching system. Summary of the Invention

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0036] like Figure 1As shown, the high-frequency heat treatment equipment for garden knives includes a controller, a feeding mechanism 100, a clamping mechanism 200, a heating mechanism 300, a guiding mechanism 400, a quenching tank 500, and a discharging mechanism 600. The controller is electrically connected to the above-mentioned mechanisms.

[0037] like Figure 1 and Figure 13 As shown, the steps of high-frequency heat treatment are as follows: the blades are stored in the feeding mechanism, the feeding mechanism conveys the blades 9 one by one to the feeding station A, the clamping mechanism grabs the blades from the feeding station and moves the blades to the heating station B, the heating mechanism heats the blade edge at the heating station, after heating is completed, the clamping mechanism releases the blades, the blades fall into the quenching station C of the quenching tank along the guide mechanism, and the unloading mechanism moves the blades to the unloading station D outside the quenching tank, waiting for subsequent processing.

[0038] I. The following is an explanation of the feeding mechanism. The feeding mechanism includes a tool holder 101, an isolation block 102, a limiting block 103, an isolation cylinder 104, and a limiting cylinder 105.

[0039] like Figure 1 As shown, the feeding mechanism is located at the upper right of the quenching tank. Figure 3 As shown, the feeding mechanism is fixed to the quenching tank via the feeding seat 106, and the tool holder is arranged at an angle (the right end of the tool holder is higher than the left end), with the cutting blades to be heat-treated stacked on the tool holder. Figure 4 As shown, the tool holder includes two parallel slide rails, on which the blade is mounted. Both ends of the blade extend horizontally out of the slide rails, and limiting plates are also provided on both sides of the blade to prevent lateral displacement of the blade.

[0040] like Figure 3 As shown, the isolation block and the limiting block are located at the lower part of the tool holder (left end exit of the tool holder), and the isolation block and the limiting block are arranged along the blade movement direction, with the isolation block located to the upper right of the limiting block.

[0041] The limiting cylinder is used to drive the limiting block to open and close. When the piston rod of the limiting cylinder extends downward, the limiting block approaches the tool holder (limiting block closed); when the piston rod of the limiting cylinder retracts upward, the limiting block moves away from the tool holder (limiting block open). The isolation cylinder is used to drive the isolation block to open and close. When the piston rod of the isolation cylinder extends downward, the isolation block approaches the tool holder (isolation block closed); when the piston rod of the isolation cylinder retracts upward, the isolation block moves away from the tool holder (isolation block open).

[0042] The loading station is located at the bottom of the tool holder and between the limiting block and the isolation block. The distance between the limiting block and the isolation block is equal to the thickness of the blade. Figure 4As shown, the limiting block is positioned in the middle, and two stop bars are located at the bottom of the limiting block, maintaining a certain horizontal distance between the stop bars (to avoid interference with the finger movement of the gripper cylinder). Isolation blocks are located on both sides of the limiting block, each driven by a separate isolation cylinder.

[0043] like Figure 3 and Figure 4 As shown, the spacer block is wedge-shaped, thicker at the top and thinner at the bottom, to facilitate its downward insertion between the two blades. Figure 4 As shown, because the blades are positioned on both sides (one blade is located on the upper left of the blade, and the other blade is located on the lower right of the blade), the blades are relatively thin, and there is a certain gap between the blades and the adjacent blades. The spacers are also positioned on both sides, with one spacer positioned just above the blade. Therefore, the spacer moves downward first and inserts between the two blades through the gap, separating one side of the two blades (creating a gap on the other side of the two blades as well). The other spacer then moves downward and inserts between the two blades through the newly created gap, completely separating the two blades.

[0044] The feeding steps of the feeding mechanism include: 1) Initial state: The limit block is closed and the isolation block is open. Due to the obstruction of the limit block, all blades are stacked on the tool holder and press down on the limit block; 2) The isolation block is closed and inserted downwards between the two bottommost blades; the bottommost blade is positioned in the loading station between the limit block and the isolation block, while the remaining blades are blocked by the isolation block; 3) The clamping mechanism clamps the blade at the loading station, the limit block opens, and the clamping mechanism removes the blade from the loading station; 4) The limit block is closed and the isolation block is open. All blades slide down the tool holder a certain distance and press down on the limit block.

[0045] II. The clamping mechanism is explained below. The clamping mechanism is located to the lower left of the feeding mechanism and above the salt bath liquid in the quenching tank.

[0046] The clamping mechanism includes a rotating frame 201, a gripper cylinder 202, and a rotating motor 203. The rotating frame is rotatably positioned above the quenching tank, and the rotating motor drives the rotating frame to rotate (rotation axis is...). Figure 7 (Vertically), a gripper cylinder is installed at each end of the rotary frame, located on one side of the loading station and the other side of the heating station. The loading station and the heating station are arranged symmetrically about the center of the rotary frame. The heating station is also located above the guide mechanism.

[0047] like Figure 5 and Figure 6As shown, the rotary motor drives the rotary frame to rotate 180 degrees counterclockwise each time, causing the two gripper cylinders to move cyclically between the loading station side and the heating station side.

[0048] Because the slide rails of the tool holder maintain a certain horizontal distance, and the stop bars also maintain a certain horizontal distance, and the gripper cylinder's fingers grip the middle of the blade, the gripper cylinder will not interfere with the tool holder or the limit block. Since the blades at the loading station are separated from adjacent blades by the isolation block, the gripper cylinder's fingers can only grip the blades at the loading station and cannot grip other blades. Because the rotary frame rotates counterclockwise, the blade moves upwards and disengages from the tool holder. Because the rotary frame rotates counterclockwise, after the limit block opens (the limit block moves away from the tool holder), the distance between the limit block and the center of the rotary frame increases, and the blade will not interfere with the limit block when moving counterclockwise.

[0049] The gripping steps of the clamping mechanism include: 1) The fingers of the gripper cylinder on one side of the loading station open ( Figure 5 As shown in Figure a), wait to grab the blade; the fingers of the gripper cylinder on one side of the heating station remain closed ( Figure 5 As shown in b), the blade is clamped, and the heating mechanism heats the blade; 2) The feeding mechanism operates, and the lowest blade is positioned in the feeding station between the limit block and the isolation block; 3) The fingers of the gripper cylinder on one side of the loading station close together ( Figure 6 Clamp the blade (as shown in a). 4) After heating is complete, the fingers of the gripper cylinder on one side of the heating station open ( Figure 6 (As shown in b), the blade falls; 5) When the limit block opens, the rotary motor drives the rotary frame to rotate 180 degrees, and the gripper cylinder holding the blade moves from the loading station to the heating station. At the same time, the gripper cylinder at the other end moves from the heating station to the loading station.

[0050] III. The heating mechanism is explained below. The heating mechanism includes a high-frequency main unit and a pair of induction coils 301. The high-frequency main unit (omitted in the figure) is electrically connected to the induction coils. The induction coils are aligned with the two blade edges of the blade located at the heating station. The high-frequency alternating current generates an alternating magnetic field in the induction coils, causing eddy currents to form on the blade edge and achieving non-contact heating.

[0051] like Figure 5 As shown, the distance between the induction coil and the center of the rotary frame is less than the distance between the heating station and the center of the rotary frame, and the induction coil is located to the upper right of the blade at the heating station. Figure 6 As shown, the induction coils are respectively set on both sides of the rotary frame.

[0052] IV. The following describes the guiding mechanism and the quenching tank. The guiding mechanism is disposed in the quenching tank. The guiding mechanism includes a pair of guide grooves 401. The guide grooves are disposed below the heating station and the induction coil, and the width of the guide grooves decreases from top to bottom.

[0053] like Figure 6 As shown, after the blade in the heating station has finished heating, the fingers of the gripper cylinder open, and the two sides of the blade fall into the guide groove. Therefore, the blade moves down the guide groove to the quenching station C of the quenching tank.

[0054] The quenching tank contains a salt bath solution, and the blade is cooled by salt bath quenching, thereby improving the blade strength. The quenching tank is also equipped with a cooling water pipe 501 for controlling the temperature of the salt bath solution.

[0055] V. The following is an explanation of the discharge mechanism. The discharge mechanism is installed in the quenching tank. The discharge mechanism includes a discharge motor 603, a transmission assembly, a pair of baffle teeth 601 and a pair of stepping teeth 602.

[0056] like Figure 2 As shown, the stop toothed plate is disposed inside the stepping toothed plate. The stop toothed plate and the stepping toothed plate are arranged at an angle. Figure 12 As shown, the top of the baffle plate is provided with several baffle grooves 621, which gradually rise from right to left. Figure 9 As shown, the top of the stepping tooth plate is provided with a plurality of stepping tooth grooves 622, which gradually rise from right to left.

[0057] The bottom of the baffle tooth plate has a baffle tooth groove located below the guide groove. This baffle tooth groove is the quenching station, and the top of the baffle tooth plate has a baffle tooth groove for discharging.

[0058] The discharge motor drives the stepper toothed plate to rotate via a transmission assembly. Figure 9 (Counterclockwise direction). Each side of the stepper tooth plate is driven by the discharge motor and transmission assembly on the same side. The discharge motor and transmission assembly are located on both sides of the quenching tank.

[0059] like Figure 8 and Figure 9 As shown, in the transmission assembly, the first sprocket 611, the second sprocket 612, the third sprocket 613 and the tension sprocket 615 are rotatably positioned on the side of the quenching tank. The chain 614 connects the first sprocket, the second sprocket, the third sprocket and the tension sprocket. The first sprocket is located between the two second sprockets. The bottom ends of the two pull rods 617 are fixed to the stepping tooth plate. The second sprockets on the same side are connected to the pull rods through a connecting rod 616. One end of the connecting rod is fixed to the second sprocket and the other end is rotatably positioned at the top of the pull rod.

[0060] The outer side of the stepper tooth plate is also provided with a quenching baffle 604 to prevent the blades in the stop tooth groove and the stepper tooth groove from moving laterally.

[0061] The discharging steps of the discharging mechanism include: 1) The blades falling along the guide groove sink into the baffle tooth groove at the bottom of the baffle tooth plate; 2) As the stepper plate rotates counterclockwise, the stepper groove of the stepper plate and the stop groove of the stopper plate move backward and backward and up and down. The stepper groove lifts the blade from the current stop groove and puts it into the stop groove of the next level. Then the stepper groove of the next level repeats the action, and the blade is put into the stop groove of the next level. 3) This process is repeated, with the blade moving upwards along the stop groove step by step to the discharge station, completing the quenching process; 4) The external mechanism removes the blade for subsequent processing.

[0062] All components of this invention are existing technologies and can be purchased externally.

[0063] The present invention has the following advantages: 1. Significantly improves the consistency and stability of product quality. Precise positioning: Automatic positioning is achieved using a gripper cylinder, which accurately controls the relative position of the blade and the induction coil, completely eliminating the positional deviation caused by manual placement.

[0064] Constant process parameters: The controller precisely controls the heating time and the speed of the stepper toothed plate, ensuring that the time rhythm of the entire process of "heating-transfer-cooling" is strictly consistent.

[0065] It effectively solves quality problems such as uneven hardening layer depth, soft spots, and large deformation. The product qualification rate can be increased from 85%-90% with manual operation to over 98%, and the quality is highly stable between batches.

[0066] 2. Significantly improve production efficiency and equipment utilization rate Seamless integration: Automatic feeding and quenching can be perfectly matched with the working rhythm of the heating mechanism, eliminating the pauses and waiting time in manual operation and realizing continuous flow production.

[0067] Capacity improvement: Production cycle time can be shortened by 30%-50%, and the daily output of a single machine can be significantly increased.

[0068] 24 / 7 operation: The equipment can support 24-hour uninterrupted operation with only a small number of personnel required for inspection, which greatly releases the production capacity potential.

[0069] 3. Reduce labor intensity, improve the working environment, and ensure safety. Human-machine isolation: Operators do not need to directly contact high-temperature workpieces and dangerous areas, fundamentally eliminating the direct harm to the human body from burns and high-frequency radiation.

[0070] Reduced labor costs: One person can manage multiple machines, significantly reducing reliance on skilled workers, lowering the company's labor and training costs, and solving the problem of recruitment difficulties.

[0071] Environmentally friendly: The semi-enclosed automatic structure is more conducive to the centralized collection of quenching fumes and exhaust gases, making it easier to install environmental protection treatment devices and improve the overall workshop environment.

[0072] 4. Energy conservation and consumption reduction By reducing wasted waiting time and rework rates, energy consumption per unit product is significantly reduced. At the same time, precise heating control avoids excessive energy waste, aligning with the trend of green manufacturing.

[0073] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the appended claims.
