Description

Technical Field

[0001] This utility model mainly relates to the field of tempering furnace technology, specifically to a tempering device for heat treatment processing. Background Technology

[0002] In heat treatment processes, tempering furnaces are key equipment for eliminating internal stress in metal workpieces after quenching, adjusting mechanical properties, and stabilizing microstructure and dimensions. Among them, there are vacuum tempering furnaces, bogie tempering furnaces, pit tempering furnaces, and mesh belt tempering furnaces. Mesh belt tempering furnaces are suitable for small-scale industry standard tempering treatment.

[0003] When processing small workpieces in a mesh belt tempering furnace, the workpieces are directly conveyed and spread on the furnace's conveyor line. Due to the lack of guidance and limiting for the spread of the workpieces, they tend to be spread at the edges of the furnace's conveyor line. Workpieces located at the edges of the furnace's conveyor line are very likely to scrape against the furnace wall or get stuck between the furnace wall and the conveyor line.

[0004] The inventors proposed a tempering device for heat treatment processing. By setting a limiting material spreading component on the feeding side of the tempering furnace conveyor line, the workpiece is prevented from being spread on the edge of the conveyor line. At the same time, a protective structure is added to prevent the workpiece from falling directly onto the conveyor belt. Utility Model Content

[0005] 1. Technical problem solved by the utility model: This invention provides a tempering device for heat treatment, which solves the technical problem of insufficient limiting of feeding and spreading in existing equipment.

[0006] 2. Technical Solution: To achieve the above objectives, the technical solution provided by this utility model is as follows: a tempering device for heat treatment processing, comprising a furnace body, wherein infrared heating components are fixedly provided at the top and bottom of the inner wall of the furnace body, a conveyor line runs through the middle of the furnace body, the top of the left and right end shells of the front feeding side of the furnace body are fixedly connected to the bottom of the left and right end of the mounting frame respectively, a guide inclined plate is fixedly provided in the middle of the mounting frame, and limiting inclined plates are fixedly provided on both the left and right sides of the guide inclined plate.

[0007] Furthermore, the bottom rear end of the guide plate extends to the upper front of the feed side of the conveyor line, the front end of the guide plate extends to the top front end of the mounting frame, and the upper front end of the guide plate mates with the discharge side of the workshop material conveyor belt.

[0008] Furthermore, the distance between the front ends of the two limiting inclined plates is greater than the distance between the rear ends of the two limiting inclined plates, and the rear ends of the limiting inclined plates extend to the upper part of the front of the feed side of the conveyor line.

[0009] Furthermore, a telescopic cylinder is movably connected to the middle of each of the two mounting brackets, and a connecting plate is movably connected to the rear output end of the telescopic cylinder. The rear end of the connecting plate is movably connected to the middle of the outer side of the inclined push plate. A connecting frame is fixed to the top of the inclined push plate, and the front ends of the two connecting frames are movably connected to the middle of the left and right ends of the mounting bracket, respectively.

[0010] Furthermore, brackets are fixedly provided at both the left and right ends of the mounting frame, and the tops of the two brackets are movably connected to the left and right ends of the rotating shaft, respectively. The left end of the rotating shaft is fixedly connected to the right output end of the geared motor, and the outer side of the geared motor is fixedly connected to the top of the bracket.

[0011] Furthermore, a bushing is fixed in the middle of the rotating shaft, and multiple retaining seats are fixed at equal intervals on both the left and right ends of the bushing. A docking seat is engaged on the outer side of the retaining seat, and a limiting baffle is engaged on the top of the docking seat. The bottom of the limiting baffle extends to the top of the guide inclined plate.

[0012] 3. Beneficial effects: Compared with the prior art, the technical solution provided by this utility model has the following advantages: This utility model provides a tempering device for heat treatment processing. The telescopic cylinder cooperates with the connecting plate to complete the deflection of the inclined push plate with the connection point of the connecting frame and the mounting frame as the center. During the deflection of the inclined push plate above the conveyor line, the workpiece that was placed on the back of the guide plate near the edge of the conveyor line is swept to the middle of the conveyor line, which effectively avoids the workpiece being spread on the edge of the conveyor line and scraping against the furnace wall. This utility model provides a tempering device for heat treatment processing. During the rotation of the limiting baffle above the guide inclined plate, the workpieces piled on the guide inclined plate are divided and pushed to prevent the workpieces on the guide inclined plate from directly sliding down and hitting the conveyor belt. The user can adjust the number of limiting baffles used on the outside of the bushing according to the size of the workpiece to be processed, so as to prevent small workpieces from directly sliding down and hitting the conveyor belt in the rotation gap of a small number of limiting baffles. The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0018] See attached document Figure 1-7This utility model provides a tempering device for heat treatment processing, including a furnace body 1. Infrared heating components 11 are fixedly installed on the top and bottom of the inner wall of the furnace body 1. A conveyor line 12 runs through the middle of the furnace body 1. The top of the left and right end shells on the front feeding side of the furnace body 1 are fixedly connected to the bottom of the left and right end of the mounting frame 2, respectively. A guide plate 21 is fixedly installed in the middle of the mounting frame 2. Limiting plates 22 are fixedly installed on both the left and right sides of the guide plate 21.

[0019] In this embodiment, the bottom rear end of the guide ramp 21 extends to the front of the feed side of the conveyor line 12, the front end of the guide ramp 21 extends to the top of the front end of the mounting frame 2, the top of the front end of the guide ramp 21 cooperates with the discharge side of the workshop material conveyor belt, the distance between the front ends of the two limiting ramps 22 is greater than the distance between the rear ends of the two limiting ramps 22, and the rear end of the limiting ramp 22 extends to the front of the feed side of the conveyor line 12.

[0020] The workpieces delivered by the factory workshop material conveyor belt fall in front of the guide sloping plate 21. The guide sloping plate 21 guides the workpieces to the front of the feed side of the conveyor line 12. The limiting sloping plate 22 guides the workpieces to slide above the guide sloping plate 21, preventing the workpieces from being scattered on the edge of the conveyor line 12.

[0021] In this embodiment, telescopic cylinders 3 are movably connected to the middle of both mounting brackets 2. A connecting plate 31 is movably connected to the rear output end of the telescopic cylinder 3. The rear end of the connecting plate 31 is movably connected to the middle of the outer side of the inclined push plate 32. A connecting bracket 33 is fixedly provided on the top of the inclined push plate 32. The front ends of the two connecting brackets 33 are movably connected to the middle of the left and right ends of the mounting bracket 2, respectively.

[0022] The telescopic cylinder 3 works in conjunction with the connecting plate 31 to complete the deflection of the inclined push plate 32 with the connection point of the connecting frame 33 and the mounting frame 2 as the center. During the deflection of the inclined push plate 32 above the conveyor line 12, the workpieces that were placed on the back of the guide plate 21 near the edge of the conveyor line 12 are swept towards the middle of the conveyor line 12, effectively preventing the workpieces from being spread on the edge of the conveyor line 12 and scraping against the furnace wall of the furnace body 1.

[0023] In this embodiment, brackets 4 are fixed at both ends of the mounting frame 2. The tops of the two brackets 4 are movably connected to the left and right ends of the rotating shaft 41, respectively. The left end of the rotating shaft (41) is fixedly connected to the right output end of the reduction motor 42. The outer side of the reduction motor 42 is fixedly connected to the top of the bracket 4. A bushing 5 is fixedly provided in the middle of the rotating shaft 41. Multiple card seats 51 are fixedly provided at equal intervals at both ends of the bushing 5. A docking seat 52 is attached to the outer side of the card seat 51. A limiting baffle 53 is attached to the top of the docking seat 52. The bottom of the limiting baffle 53 extends to the top of the guide inclined plate 21.

[0024] To prevent workpieces from falling too quickly from the guide ramp 21 onto the conveyor line 12 and causing damage to the conveyor belt, a drive motor is used to rotate the shaft 41, which in turn rotates the bushing 5, thus setting the limit baffle 53 to rotate above the guide ramp 21.

[0025] As the limiting baffle 53 rotates above the guide ramp 21, it divides and pushes the workpieces piled on the guide ramp 21, preventing the workpieces on the guide ramp 21 from directly sliding down and hitting the mesh belt of the conveyor line 12. The user can adjust the number of limiting baffles 53 used on the outside of the bushing 5 according to the size of the workpiece to be processed, so as to prevent small workpieces from directly sliding down and hitting the mesh belt of the conveyor line 12 in the rotation gap of a small number of limiting baffles 53.

[0026] The above-described embodiments are merely illustrative of certain implementations of this utility model, and their descriptions are relatively specific and detailed. However, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
