Technical Field

[0001] The present invention relates to a heat treatment device, and in particular, to a tempering device for slender rods. Background Art

[0002] At present, Chinese Patent No. CN109554520A discloses a mesh belt type hot air circulation tempering furnace, including a mesh belt, a hot air circulation mechanism, and a hot air treatment mechanism. Both ends of the mesh belt are sleeved on the surface of a roller. A rotating shaft is sleeved inside each of the two rollers. The two rotating shafts are rotatably connected to both ends of a frame. A driven pulley is fixedly connected to the surface of the rotating shaft on the left side. The driven pulley is connected to a driving pulley through a transmission belt. The driving pulley is fixedly connected to the output end of a motor. The top of the motor is fixedly connected to a furnace body.

[0003] One side of the top of the furnace body is fixedly connected to a combustion box. A burner is fixedly connected to the bottom inner wall of the combustion box. One end of a high-temperature pipe is communicated and installed on one side of the combustion box. The other end of the high-temperature pipe is fixedly connected to the air inlet end of a first blower. The first blower is fixedly connected to the top surface of the furnace body through a first blower frame. The air outlet end of the first blower penetrates through the top of the furnace body and is fixedly connected to the top of a cross pipe. A number of identical air nozzles are equidistantly communicated and installed at the bottom of the cross pipe for spraying hot air on the surface of the material. A return air pipe is communicated and installed at the top of the furnace body. The top end of the return air pipe is communicated and installed on the side wall of the combustion box far from the high-temperature pipe.

[0004] However, when using the above tempering furnace to temper slender rods, the positions of the slender rods on the surface of the transmission belt remain unchanged. In this way, it is very easy to affect the tempering effect of the slender rods due to uneven heating of the slender rods. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a tempering device for slender rods, which has the advantages of uniform heating of slender rods and not being easily affected by the tempering effect.

[0006] To solve the above technical problems, the technical solution of the present invention is: a tempering device for slender rods, including a tempering furnace body and a tempering furnace base. An inlet is provided on the front side of the tempering furnace body, and an outlet is provided on the rear side of the tempering furnace body. The tempering furnace base is arranged at the lower end of the tempering furnace body. A driving wheel is rotatably arranged on the front side of the tempering furnace base, and the driving wheel is located outside the inlet. A driven wheel is rotatably connected to the rear side of the tempering furnace base, and the driven wheel is located outside the outlet. A transmission belt is sleeved between the driving wheel and the driven wheel. The transmission belt includes a number of transmission iron sheets hinged to each other. Transmission teeth are arranged on the inner side of the transmission iron sheets. A number of transmission grooves for the transmission teeth to engage are provided on the outer sides of both the driving wheel and the driven wheel, and the number of the transmission grooves is equidistantly distributed along the circumferential direction. A clamping seat is arranged on the outer side of the transmission iron sheet. A clamping groove for a slender rod to be inserted is provided at the end of the clamping seat away from the transmission iron sheet. A driving mechanism is arranged in the clamping seat. When the slender rod is inserted into the clamping groove, the output end of the driving mechanism abuts against the outer wall of the slender rod to drive the slender rod to rotate in the clamping groove.

[0007] Through the above technical solution, during use, the slender rods to be processed are successively inserted into the clamping grooves at the inlet. At the same time, a driving element such as a servo motor is used to drive the driving wheel to rotate circumferentially. The driving wheel and the driven wheel cooperate to drive the transmission belt to move from the inlet to the outlet, so as to convey the slender rods to be processed into the tempering furnace body, and then temper the slender rods. During the process of the transmission belt conveying the slender rods into the tempering furnace body, the driving mechanism is used to drive the slender rods to rotate in the clamping grooves, so that the slender rods can be heated more evenly, and the tempering effect of the slender rods is not easily affected. The transmission teeth and the transmission grooves cooperate with each other to avoid slipping, thereby improving the transmission efficiency between the driving wheel and the transmission belt.

[0008] Preferably, the clamping seat includes a front clamping block and a rear clamping block. The front clamping block is arranged on the front side of the transmission iron sheet, and the rear clamping block is arranged on the rear side of the transmission iron sheet. A clamping groove is formed between the rear clamping block on the front transmission iron sheet and the front clamping block on the rear transmission iron sheet.

[0009] Through the above technical solution, when the transmission belt moves to be opposite to the driven wheel, the front clamping block and the rear clamping block are in an open state. At this time, the worker can conveniently put the slender rod into the clamping groove. When the transmission belt moves between the driven wheel and the driving wheel, the front clamping block and the rear clamping block can clamp the slender rod, so that the slender rod is not easily separated. When the transmission belt moves to be opposite to the driving wheel, the front clamping block and the rear clamping block are in an open state. At this time, the worker can conveniently take out the slender rod.

[0010] Preferably, a front arc-shaped support surface is provided on the front side of the front clamping block, and a rear arc-shaped support surface is provided on the rear side of the rear clamping block. Both the front arc-shaped support surface and the rear arc-shaped support surface are used to support the slender rod.

[0011] Through the above technical solution, when the conveyor belt moves to face the driving wheel, the rear arc-shaped support surface can support and limit the slender rod, so that the slender rod is not easily scattered randomly, thereby improving the blanking efficiency of the slender rod. When the conveyor belt moves to face the driven wheel, the front arc-shaped support surface can support and limit the slender rod, so that the slender rod is not easily scattered randomly, thereby improving the feeding efficiency of the slender rod.

[0012] Preferably, a front extension flange is provided on the rear side of the front clamping block, and a front mounting bolt is disposed through the front extension flange. The front mounting bolt presses and fixes the front extension flange on the outside of the transmission iron sheet. A rear extension flange is provided on the front side of the rear clamping block, and a rear mounting bolt is disposed through the rear extension flange. The rear mounting bolt presses and fixes the rear extension flange on the outside of the transmission iron sheet.

[0013] Through the above technical solution, the front mounting bolt presses and fixes the front clamping block and the transmission iron sheet through the front extension flange, making the disassembly and assembly of the front clamping block more convenient. The rear mounting bolt presses and fixes the rear clamping block and the transmission iron sheet through the rear extension flange, making the disassembly and assembly of the rear clamping block more convenient.

[0014] Preferably, the driving mechanism includes a driving cross plate, a front runner and a rear runner. The driving cross plate is disposed on the side of the conveyor belt, and the driving cross plate is fixedly connected to the tempering furnace base through a bracket. Anti-slip lines are staggered on the upper end of the driving cross plate. A front mounting hole is formed in the side wall of the front clamping block close to the driving cross plate, and the front mounting hole penetrates upward through the front arc-shaped support surface. The front runner is rotatably connected in the front mounting hole. The upper end of the front runner protrudes from the upper opening of the front mounting hole, and the end of the front runner protrudes from the side opening of the front mounting hole. The lower end of the front runner abuts against the upper end of the driving cross plate. A rear mounting hole is formed in the side wall of the rear clamping block close to the driving cross plate, and the rear mounting hole penetrates upward through the rear arc-shaped support surface. The rear runner is rotatably connected in the rear mounting hole. The upper end of the rear runner protrudes from the upper opening of the rear mounting hole, and the end of the rear runner protrudes from the side opening of the rear mounting hole. The lower end of the rear runner abuts against the upper end of the driving cross plate.

[0015] Through the above technical solution, during the process of the conveyor belt transporting the slender rod to the inner side of the tempering furnace body, the front-side runner and the rear-side runner come into contact with the driving cross plate and rotate circumferentially under the action of the driving cross plate. At the same time, the front-side runner and the rear-side runner drive the slender rod to rotate, so that the slender rod is heated more evenly. By using the movement of the conveyor belt as the power to drive the rotation of the slender rod through the driving cross plate, the front-side runner and the rear-side runner, the use of the above tempering device becomes more energy-efficient. Moreover, if driving components such as motors are installed on the conveyor belt, the driving components such as motors are likely to be damaged in a high-temperature environment.

[0016] Preferably, the driving mechanism further includes an auxiliary frame, a pressing runner and a pressing holding rod. The lower end of the auxiliary frame is rotatably connected to the side wall of the rear clamping block. The upper end of the auxiliary frame extends above the rear clamping block. An elastic resetting member is arranged between the auxiliary frame and the rear clamping block. The pressing runner is rotatably connected to the bottom surface of the upper end of the auxiliary frame. The pressing holding rod is arranged in the tempering furnace body. When the pressing holding rod touches the auxiliary frame, the pressing holding rod drives the auxiliary frame to turn towards the clamping groove, so that the pressing runner abuts against the slender rod.

[0017] Through the above technical solution, during the process of the conveyor belt transporting the slender rod to the inside of the tempering furnace body, the pressing holding rod abuts against the auxiliary frame and drives the auxiliary frame to rotate clockwise until the pressing runner abuts against the slender rod in the clamping groove. By restricting the slender rod with the pressing runner, the slender rod is not easily lifted upwards.

[0018] Preferably, a plurality of annular grooves are formed on the outer sides of the front-side runner, the rear-side runner and the pressing runner, and the annular grooves on the outer side of the front-side runner, the annular grooves on the outer side of the rear-side runner and the annular grooves on the outer side of the pressing runner are arranged in a staggered manner along the axial direction.

[0019] Through the above technical solution, the annular grooves can reduce the contact area between the front-side runner, the rear-side runner and the pressing runner and the slender rod, so that the slender rod can be heated more fully and efficiently.

[0020] Preferably, a plurality of fan blades are arranged in the annular groove of the front-side runner, and the plurality of fan blades are evenly distributed along the circumferential direction of the front-side runner.

[0021] Through the above technical solution, during the rotation of the front-side runner, the hot air inside the tempering furnace body can be disturbed by the plurality of fan blades, so that the slender rod can be heated more fully and evenly. Description of the Drawings
