Description

Technical Field

[0001] The invention relates to the field of forging furnace structures, in particular to an electric heating forging furnace used for producing and processing crawler iron teeth. Background Art

[0002] Forging is a method of shaping a material without removing any material. In practice, the material must first be heated to a certain temperature, then pressurized to cause plastic deformation and form the material. Therefore, heating the material is an essential step in hot forging.

[0003] Application No. 202221222612.1 is a heating furnace with a uniform heating function for processing rubber track iron teeth, comprising a main body, one end of the main body being set as a discharge port for discharging materials, the other end being set as a feed port for feeding materials, the upper end being provided with a motor for transmission, and the lower end being provided with a support frame for support, a plurality of annular protrusions being provided on the inner wall of the main body, and a No. 2 rack for transmission being provided in the annular protrusions, through the setting of the sleeve, the motor at the upper end of the main body is driven to rotate in the main body, thereby turning the material in the sleeve over, so that the material in the sleeve is heated more evenly; through the setting of the baffle, one end of the baffle is connected to the feed port through a rotating shaft, and the other end is sleeved and connected with an arc rod, and the baffle is opened by the pushing device when in use, and is in a closed state when not in use, thereby effectively preventing the heat inside the main body from leaking out.

[0004] This solution uses a spiral turning method to heat the material in all directions. However, the actual forging furnace temperature is relatively high, and the track teeth are relatively heavy, making the spiral turning method difficult to implement. Summary of the Invention

[0009] The support assembly includes a platform, rollers, a support mechanism and a displacement plate. There are two groups of rollers, which are respectively installed on both sides of the bottom of the platform. The two groups of rollers correspond to two tracks respectively. There are multiple support mechanisms, which are fixed in parallel on the platform. The lifting assembly is interspersed with multiple support mechanisms. There are multiple displacement plates, which are fixed to the platform. The displacement plate is located between any two support mechanisms. There are two placement slots A on the displacement plate for the lifting assembly to pass through. Wedge blocks are fixedly installed on both sides of the displacement plate, and the corner position of the wedge block is arc-shaped.

[0010] Preferably, the supporting mechanism includes a frame and pyramids. The pyramids are provided in two groups, each group having four pyramids. The pyramids are fixed on the inner bottom wall of the frame, and the two groups are distributed side by side on the frame.

[0011] Preferably, the upper end of the frame is provided with two placement slots B for the lifting components to pass through.

[0012] Preferably, the lifting assembly includes a strip and two power groups. The strip passes through the placement slot A and the placement slot B. The strip is fixed in the position of the frame with two symmetrical forks, one of which is installed on the furnace body, and the other is installed on the furnace body and the inclined rail. The two power groups act on the two strips to lift the strips obliquely in the placement slot A and the placement slot B.

[0013] Preferably, the power group includes a runner, a push rod, a swing arm and a hydraulic cylinder. There are two runners, both of which are located in the furnace body and rotatably connected thereto. The push rod is fixedly connected to the two runners and fixed at the eccentric point of the runner. The push rod is rotatably connected to the two slats. The power group near the closed door includes a push rod rotatably installed with two clamping plates, which are clamped on the slats. The main shaft at one end of the swing arm passes through the furnace body and is connected to the main shaft of the runner. The fixed end of the hydraulic cylinder is hinged to the furnace body, and the output end of the hydraulic cylinder is hinged to the end of the swing arm away from the main shaft of the runner.

[0014] Preferably, the main shaft of the wheel close to the closed door is connected to the main shaft of the swing arm by a quick-release part, the wheel away from the closed door is fixed to the furnace body by a wheel frame, and the wheel close to the closed door is movably connected to the furnace body by a wheel frame, and the wheel frame is slidably installed in the inclined rail and can be fixed on the inclined rail.

[0015] (3) Beneficial effects

[0016] The present invention provides an electrically heated forging furnace for the production and processing of crawler gears. It has the following beneficial effects:

[0017] 1. The track tooth processing and forging furnace is provided with a support assembly and a lifting assembly. When firing and forging track teeth, the track teeth are placed on the pyramid. The two sets of pyramids jointly support the track teeth and are restricted in their left and right positions by two adjacent displacement plates. When the platform is pushed into the furnace body, the track teeth are not easily changed in position or dropped. Due to the support of the pyramids, the upper three surfaces of the track teeth can be heated. Since the bottom of the track teeth is less obstructed, the bottom can also be heated. After a period of heating, the hydraulic cylinder extends to rotate the runner to a certain angle. At this time, the two push rods can lift the two strips. When the strips are lifted, they will shift to a certain position. The shift fork on the strip will push the track teeth, causing them to press against the wedge blocks on the displacement plates. Due to the inclination of the wedge blocks and the inclination of the shift fork, the track teeth can be turned over under a large force. After the strips are lowered, the track teeth turn over and return to the pyramids, thereby allowing the track teeth to be heated in all directions.

[0018] 2. The crawler iron tooth processing forging furnace is provided with a platform. When the platform is moved out, the power group and the slats near the closed door are disassembled, and the quick-release parts between the runner and the swing arm on the same side are also disconnected. At this time, the power group is moved to the lower end of the inclined rail, and the platform can be moved out of the furnace body, making it easier to push in and out parts.

The support assembly 6 slides relative to the furnace body 1 according to the two rails 4; it also includes a lifting assembly 7.

[0029] The supporting assembly 6 includes a platform 601, rollers 602, a supporting mechanism 603 and a displacement plate 604. There are two groups of rollers 602, which are respectively installed on both sides of the bottom of the platform 601. The two groups of rollers 602 correspond to two tracks 4 respectively. There are multiple supporting mechanisms 603, which are fixed in parallel on the platform 601. The lifting assembly 7 is interspersed with multiple supporting mechanisms 603. There are multiple displacement plates 604, which are fixed to the platform 601. The displacement plate 604 is located between any two supporting mechanisms 603. The displacement plate 604 is provided with two placement slots A605 for the lifting assembly 7 to pass through. Wedge blocks 606 are fixedly installed on both sides of the displacement plate 604, and the corner position of the wedge block 606 is arc-shaped.

[0030] The furnace body 1 is an electric heating furnace, which is heated by an electric heating coil. The roller 602 at the bottom of the platform 601 is not easily affected by high temperature when sliding on the track 4.

[0031] The supporting mechanism 603 includes a frame 6031 and pyramids 6032 . The pyramids 6032 are provided in two groups, each group having four pyramids. The pyramids 6032 are fixed on the inner bottom wall of the frame 6031 , and the two groups are distributed side by side on the frame 6031 .

[0032] The upper end of the pyramid 6032 is a pointed flat structure, and multiple pyramids 6032 can jointly support a track tooth. When the track tooth is heated, the bottom surface of the track tooth can also be heated.

[0033] The upper end of the frame 6031 is provided with two placement slots B6033 for the lifting assembly 7 to pass through.

[0034] The lifting assembly 7 includes a strip 701 and two power groups 702. The strip 701 passes through the placement slot A605 and the placement slot B6033. The strip 701 is located in the frame 6031 and is fixed with two symmetrical shift forks 703. One power group 702 is installed on the furnace body 1, and the other power group 702 is installed on the furnace body 1 and the inclined rail 5. The two power groups 702 act on the two strips 701 to lift the strips 701 obliquely in the placement slot A605 and the placement slot B6033.

[0035] The two shift forks 703 are located in a frame 6031, and their upper ends are spread away from each other with a certain oblique angle. When supporting the track iron teeth, the two shift forks 703 can clamp the entire track iron teeth to prevent them from falling.

[0036] The power group 702 includes a rotating wheel 7021, a top rod 7022, a swing arm 7023 and a hydraulic cylinder 7024. There are two rotating wheels 7021, both of which are located in the furnace body 1 and are rotatably connected thereto. The top rod 7022 is fixedly connected to the two rotating wheels 7021 and is fixed at the eccentric point of the rotating wheel 7021. The top rod 7022 is rotatably connected to the two slats 701. The top rod 7022 included in the power group 702 near the closed door 2 is rotatably installed with two clamping plates 7025, which are clamped on the slats 701. The main shaft at one end of the swing arm 7023 passes through the furnace body 1 and is connected to the main shaft of the rotating wheel 7021. The fixed end of the hydraulic cylinder 7024 is hinged to the furnace body 1, and the output end of the hydraulic cylinder 7024 is hinged to the end of the swing arm 7023 away from the main shaft of the rotating wheel 7021.

[0037] The top rods 7022 and the rotating wheels 7021 of the two power groups 702 are installed at the same angle. The connection between the clamping plate 7025 and the strip plate 701 is fixed with bolts or connected with quick-release screws. The clamping plate 7025 can be quickly removed from the strip plate 701.

[0038] The main shaft of the rotating wheel 7021 close to the closed door 2 and the main shaft of the swing arm 7023 are connected by quick-release parts, and the rotating wheel 7021 away from the closed door 2 is fixed to the furnace body 1 by a wheel frame. The rotating wheel 7021 close to the closed door 2 is movably connected to the furnace body 1 by a wheel frame, and the wheel frame is slidably installed in the inclined rail 5 and can be fixed on the inclined rail 5.

[0039] The quick-release part is a quick-release coupling. After the runner 7021 moves to a specific position, it is connected to the furnace body 1 using bolts, and then the power is connected according to the coupling.

[0040] When in use, push in the platform 601, remove the power group 702 near the closed door 2 from the inclined rail 5 and fix it, and then connect it to the strip 701 and the swing arm 7023 respectively. When firing and forging the track teeth, the track teeth are placed on the pyramid 6032. The two groups of pyramids 6032 jointly support the track teeth and are restricted in their left and right positions by the two adjacent displacement plates 604. When the platform 601 is pushed into the furnace body 1, the track teeth are not easy to change their positions. After heating for a period of time, the hydraulic cylinder 7024 extends to make the runner 7021 rotate a certain angle. At this time, the two push rods 7022 can lift the two strips 701. The strips 701 are lifted When the platform 601 is moved out, the power group 702 near the closed door 2 is disassembled from the strip 701, and the quick-release parts between the runner 7021 and the swing arm 7023 on the same side are also disconnected. At this time, the power group 702 is moved to the lower end of the inclined rail 5, and the platform 601 can be moved out of the furnace body 1.
