Description

Technical Field

[0001] This invention belongs to the field of chainsaw guide plate quenching technology, and relates to a chainsaw guide plate quenching device and quenching method. Background Technology

[0002] Chainsaws are cutting tools used to cut wood, stone, steel, and other materials. In the structure of an electric chainsaw, the chain-like saw blade is positioned between two guide plates. The guide plates are made by stamping rolled metal sheets. After the shape and positioning holes are stamped out, the surface of the guide plate is subjected to high-frequency quenching to improve its strength. Currently, the quenching of chainsaw guide plates involves manually transporting the guide plates to a heating machine for heating, and then quickly transferring them to water for cooling. Because chainsaw guide plates are made of high-carbon steel, if the chainsaw guide plates are not properly tempered and are then immersed in water for instantaneous cooling, the chainsaw guide plates will become very brittle, making them extremely prone to breakage and damage during use. In contrast, chainsaw guide plates that are naturally quenched and cooled not only maintain their strength and hardness but also possess good toughness. Summary of the Invention

[0003] The purpose of this invention is to address the above-mentioned problems by providing a quenching device for chainsaw guide plates.

[0004] Another object of the present invention is to provide a quenching method for a chainsaw guide plate quenching device.

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

[0006] A chainsaw guide plate quenching device includes a frame, a chainsaw guide plate heating mechanism on the frame, an induction heating coil on the chainsaw guide plate heating mechanism, a chainsaw guide plate support seat below the induction heating coil, a belt conveyor in front of the frame, and a feeding mechanism between the belt conveyor and the induction heating coil to transport the chainsaw guide plate on the chainsaw guide plate support seat to the belt conveyor after heating.

[0007] The chainsaw guide plate is fixedly placed on the chainsaw guide plate support and heated by the induction heating coil on the chainsaw guide plate heating mechanism. After the chainsaw guide plate is heated, the unloading mechanism can transport it to the belt conveyor. The chainsaw guide plate is transported along with the belt conveyor. During the transport process, the chainsaw guide plate undergoes natural and slow cooling to complete self-cooling quenching, which not only ensures its strength and hardness but also gives it good toughness.

[0008] In the above-mentioned chainsaw guide plate quenching device, the chainsaw guide plate heating mechanism includes two plates mounted on the frame, and a coil mounting slot is provided between the two plates. The induction heating coil is mounted in the coil mounting slot and connected to the two plates through an adjustable fixing structure. The induction heating coil is U-shaped and its front end is narrowed and connected to the induction heating coil controller.

[0009] The induction heating coil is set in the coil mounting slot and fixedly connected to the two platform plates through an adjustable fixing structure. The adjustable fixing structure can adjust the fixed position of the induction heating coil in the coil mounting slot, making it flexible and convenient to adjust. The induction heating coil controller controls the induction heating coil to heat up the chainsaw guide plate quickly.

[0010] In the aforementioned chainsaw guide plate quenching device, the adjustable fixing structure includes a clamping plate set on the rear end of the induction heating coil. The plate is provided with several adjustment fixing holes distributed along the length of the coil mounting slot. The two ends of the clamping plate are respectively connected to the adjustment fixing holes of the two plates by adjustment bolts. The front end of the induction heating coil is connected to the induction heating coil controller through an extension rod. The extension rod is set on an extension rod bracket.

[0011] The clamp on the rear end of the induction heating coil serves to fix the induction heating coil. The position of the clamp can be flexibly adjusted by adjusting the adjusting bolts and adjusting the fixing holes on the platform, thereby achieving the purpose of flexibly adjusting the fixed position of the induction heating coil.

[0012] In the above-mentioned chainsaw guide plate quenching device, several positioning top blocks are respectively provided on both sides of the induction heating coil along the length direction of the induction heating coil. The positioning top blocks are respectively connected to the adjustment and fixing holes by bolts. A slot width adjustment component is provided between the two platform plates and the frame.

[0013] Several positioning blocks on both sides of the induction heating coil play a role in positioning and fixing the induction heating coil, making the fixed connection of the induction heating coil more stable. The slot width adjustment component can flexibly adjust the slot width of the coil installation through slot between the two platforms.

[0014] In the above-mentioned chainsaw guide plate quenching device, the slot width adjustment component includes slot width adjustment slots with a T-shaped cross section respectively arranged on both sides of the frame, and the two ends of the platform are respectively connected to the slot width adjustment slots by bolts.

[0015] The distance between the two platforms can be flexibly adjusted, and they are respectively fixedly connected to the slot width adjustment slot by bolts to achieve the purpose of flexibly adjusting the width of the coil installation slot.

[0016] In the aforementioned chainsaw guide plate quenching device, the feeding mechanism includes a guide frame disposed below the induction heating coil.

The inner end of the guide frame is located below the induction heating coil and on the side away from the belt conveyor. The outer end of the guide frame is disposed on the feeding end of the belt conveyor. A chainsaw guide plate support seat is provided on one side of the guide frame. The chainsaw guide plate support seat is connected to the lifting assembly.

[0017] After the chainsaw guide plate is heated, the lifting assembly drives the chainsaw guide plate support to descend. During the descent, the chainsaw guide plate moves along the guide surface at the top of the guide frame to the feed end of the belt conveyor and is naturally and slowly cooled on the belt conveyor. The guide surface plays a guiding role.

[0018] In the above-mentioned chainsaw guide plate quenching device, the lifting assembly includes a lifting cylinder, there are two guide frames located below the two ends of the induction heating coil, each guide frame has a chainsaw guide plate support seat on one side, the chainsaw guide plate support seat is connected to the lifting shaft of the lifting cylinder, the bottom of each guide frame is provided with an adjustment base plate, the lifting cylinder is set on its respective adjustment base plate, and the two adjustment base plates are connected to the transverse adjustment structure.

[0019] The chainsaw guide plate support is connected to the lifting shaft of the lifting cylinder. After the chainsaw guide plate on the support is heated, the lifting shaft of the lifting cylinder retracts, driving the chainsaw guide plate support to descend. The chainsaw guide plate then moves along the guide surface to the belt conveyor. There are two guide surfaces and chainsaw guide plate supports, located below both ends of the induction heating coil. The two chainsaw guide plate supports located below both ends of the induction heating coil ensure that the chainsaw guide plate is placed in a balanced and stable manner. The two guide surfaces located below both ends of the induction heating coil ensure that the chainsaw guide plate is smoothly guided onto the belt conveyor. The guide frame and the lifting cylinder are fixedly connected to the adjusting base plate, enabling synchronous adjustment.
