Description

Technical Field

[0001] The present invention relates to the field of metal processing or treatment, and particularly relates to an automatic loading and unloading device for a copper ingot heating furnace. Background Art

[0002] Before deep processing of copper profiles, the copper ingots need to be heated. Generally, the copper ingots are heated by an electromagnetic induction heating furnace. Before and after the copper ingots are heated, generally, workers cooperate with machines for loading and unloading. The automation degree is not high, and there is a certain danger when workers operate. Moreover, generally, the copper ingots are relatively large and heavy when heated, and it is time-consuming and laborious to operate.

[0003] For this reason, the Chinese invention patent with the patent number 201721617944.9 discloses a copper ingot heating production line, including a feeding box. The upper surface of the feeding box is provided with a feeding port. The top of the inner cavity of the feeding box is fixedly installed with a hydraulic rod. The bottom of the inner cavity of the feeding box is fixedly connected with a connecting plate. A processing box is inserted into the connecting plate. The bottom end of the hydraulic rod extends into the inside of the processing box. In this copper ingot heating production line, by setting the hydraulic rod, the connecting block and the movable block, the placement cavity formed between the connecting block and the movable block can only accommodate one copper ingot. The placement cavity is driven by the hydraulic rod to move. When the placement cavity contacts the discharge port, the copper ingot automatically slides out, enters the connecting pipe through the discharge box, and finally enters the heating furnace for heating, achieving the purpose of automatic transportation, solving the problem that the transportation method is too cumbersome due to manual handling, resulting in the obstruction of the processing progress, and thus reducing the labor intensity of the staff.

[0004] By studying the above copper ingot heating production line, it is found that it can only heat copper ingots of one size and cannot heat copper ingots of different sizes. When it is necessary to heat copper ingots of other sizes, a heating production line for copper ingots of other sizes is also required, increasing the cost.

[0005] Therefore, we urgently need to invent a device that can heat copper ingots of different sizes to solve the above problems. Summary of the Invention

[0006] In view of the above problems, the present invention provides an automatic loading and unloading device for a copper ingot heating furnace. By setting a fully automatic intermittent feeding mechanism and a fully automatic intermittent discharging mechanism, fully automatic operation of loading and unloading is realized, without manual intervention, greatly increasing the working efficiency and at the same time improving the safety of workers. By setting a variable electromagnetic induction heating mechanism, the diameter of the electromagnetic coil can be changed, so that copper ingots of different sizes can be completed on one device, saving costs.

[0007] The technical solution used in the present invention is: an automatic loading and unloading device for a copper ingot heating furnace, comprising: a support frame, a fully automatic intermittent feeding mechanism, a variable electromagnetic induction heating mechanism, a fully automatic intermittent discharging mechanism, shaft A and shaft B;

[0008] The support frame is composed of a bottom support frame, vertical plate A, vertical plate B, vertical rods, upper layer plate, limit block A and limit block B. Above the upper layer plate, two round rod slides are installed. A clamping plate is slidably installed on the round rod slides. A spring is sleeved on one of the round rod slides. The spring is arranged between the clamping plate and the fixed small plate of the upper layer plate. A buckle is installed on the small column of the upper layer plate. The head of the buckle is stuck on the side of the clamping plate. The tail of the buckle is connected to the fixed small plate of the upper layer plate through the spring. The upper parts of two vertical rods are fixed with feeding chutes. One side of the feeding chute is fixed on the vertical rod, and the other side is fixed above the vertical plate A. Shaft A is rotatably installed in the through holes of the bottom support frame, vertical plate A and the feeding chute. The upper end of shaft A is fixedly installed with a dial rod, the middle is fixedly installed with a semi-toothed gear, and the lower end is fixedly installed with a driven gear. The driven gear meshes with the gear on the stepping motor. The stepping motor is fixed on the vertical plate A. Shaft B is fixedly installed in the through holes of the bottom support frame and the vertical plate B. A sector clamping plate is rotatably installed in the middle of shaft B. The teeth on the sector clamping plate can mesh with the teeth of the semi-toothed gear. A torsion spring is also sleeved on shaft B. The torsion spring is arranged below the sector clamping plate. One end is stuck on the small column of the sector clamping plate, and the other end is stuck on the vertical plate B. The variable electromagnetic induction heating mechanism is installed on the limit block A and the limit block B;

[0009] When the device needs to be used, the copper ingots slide down in a row from the feeding chute. The first copper ingot slides onto the clamping plate. The stepping motor drives the driven gear to rotate. The driven gear drives shaft A to rotate, thereby driving the dial rod to rotate clockwise. When rotating, the short rod on the dial rod will first touch the buckle, and then the buckle rotates, thus disengaging from the clamping plate. The clamping plate slides under the elastic force of the spring until the round hole on the clamping plate slides below the copper ingot. The copper ingot falls into the variable electromagnetic induction heating mechanism through the round hole. Then, the variable electromagnetic induction heating mechanism heats the copper ingot. After heating is completed, the stepping motor continues to rotate, driving shaft A to rotate, thereby driving the semi-toothed gear to rotate. The semi-toothed gear drives the sector clamping plate to rotate. When the round hole on the sector clamping plate rotates to align with the round hole of the variable electromagnetic induction heating mechanism, the copper ingot falls into the discharging chute, thereby outputting the copper ingot. When the teeth on the semi-toothed gear and the sector clamping plate disengage, the sector clamping plate resets under the action of the torsion spring.

[0010] Further, when the copper ingot falls into the variable electromagnetic induction heating mechanism, while the clamping plate slides, the side plate on the clamping plate will clamp the next copper ingot to prevent it from sliding down.

[0011] Further, the semi-toothed gear and the lever are both fixedly installed on shaft A. That is, when shaft A rotates one circle, the blanking and loading of one process are completed. First, blanking is performed, and then loading is carried out.

[0012] Further, the stepper motor adopted by the device will not accumulate the error of one step to the next step, and has good position accuracy and motion repeatability.

[0013] Further, when the copper ingot drops onto the variable electromagnetic induction heating mechanism, the dropped copper ingot will drop to the center of the electromagnetic coil under the action of the elastic piece, so as to ensure uniform heating.

[0014] Further, the variable electromagnetic induction heating mechanism of the device can change the diameter of the electromagnetic coil, so as to adapt to copper ingots of different sizes.

[0015] Since the present invention adopts the above technical solutions, the present invention has the following advantages:

[0016] (1) By setting up a fully automatic intermittent feeding mechanism and a fully automatic intermittent blanking mechanism, the full automation of loading and unloading is realized, without manual intervention, greatly increasing the work efficiency and at the same time improving the safety of workers;

[0017] (2) By setting up a variable electromagnetic induction heating mechanism, the diameter of the electromagnetic coil can be changed, so that copper ingots of different sizes can be completed on one device, saving costs. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0028] The technical solutions of the present invention will be further specifically described below through embodiments in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present invention, but the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0029] Embodiment, as Figures 1-9 shown, an automatic loading and unloading device for a copper ingot heating furnace includes: a support frame 1, a full-automatic intermittent feeding mechanism 2, a variable electromagnetic induction heating mechanism 3, a full-automatic intermittent discharging mechanism 4, a shaft A 5 and a shaft B 6;

[0030] The support frame 1 is composed of a bottom support frame 101, a vertical plate A102, a vertical plate B103, a vertical rod 104, an upper layer plate 105, a limit block A106, and a limit block B107. Above the upper layer plate 105, two round rod slides 203 are installed. A clamping plate 202 is slidably installed on the round rod slides 203. A spring 206 is sleeved on one of the round rod slides 203. The spring 206 is arranged between the clamping plate 202 and the fixed small plate of the upper layer plate 105. A buckle 205 is installed on the small column of the upper layer plate 105. The head of the buckle 205 is stuck on the side of the clamping plate 202. The tail of the buckle 205 is connected to the fixed small plate of the upper layer plate 105 through a spring. At the upper parts of the two vertical rods 104, a feeding chute 201 is fixed. One side of the feeding chute 201 is fixed on the vertical rod 104, and the other side is fixed above the vertical plate A102. A shaft A5 is rotatably installed in the through holes of the bottom support frame 101, the vertical plate A102, and the feeding chute 201. At the upper end of the shaft A5, a lever 204 is fixedly installed. In the middle, a semi-toothed gear 403 is fixedly installed. At the lower end, a driven gear 402 is fixedly installed. The driven gear 402 meshes with the gear on the stepping motor 401. The stepping motor 401 is fixed on the vertical plate A102. A shaft B6 is fixedly installed in the through holes of the bottom support frame 101 and the vertical plate B103. In the middle of the shaft B6, a sector clamping plate 404 is rotatably installed. The teeth on the sector clamping plate 404 can mesh with the teeth of the semi-toothed gear 403. A torsion spring 405 is also sleeved on the shaft B6. The torsion spring 405 is arranged below the sector clamping plate 404. One end is stuck on the small column of the sector clamping plate 404, and the other end is stuck on the vertical plate B103. A variable electromagnetic induction heating mechanism 3 is installed on the limit block A106 and the limit block B107;

[0031] When the device needs to be used, the copper ingots slide down in a row from the feeding chute 201. The first copper ingot slides onto the clamping plate 202. The stepping motor 401 drives the driven gear 402 to rotate. The driven gear 402 drives the shaft A5 to rotate, thereby driving the lever 204 to rotate clockwise. When rotating, the short rod on the lever 204 will first touch the buckle 205, and then the buckle 205 rotates, thus disengaging from the clamping plate 202. The clamping plate 202 slides under the elastic force of the spring 206 until the round hole on the clamping plate 202 slides under the copper ingot. The copper ingot falls through the round hole into the variable electromagnetic induction heating mechanism 3. Then, the variable electromagnetic induction heating mechanism 3 heats the copper ingot. After the heating is completed, the stepping motor 401 continues to rotate, driving the shaft A5 to rotate, thereby driving the semi-toothed gear 403 to rotate. The semi-toothed gear 403 drives the sector clamping plate 404 to rotate. When the round hole on the sector clamping plate 404 rotates to align with the round hole of the variable electromagnetic induction heating mechanism 3, the copper ingot falls into the discharging chute 406, thus outputting the copper ingot. When the teeth on the semi-toothed gear 403 disengage from the teeth on the sector clamping plate 404, the sector clamping plate 404 resets under the action of the torsion spring 405.

[0032] Examples, such as Figures 4-5 As shown, the fully automatic intermittent feeding mechanism 2 includes: a feeding chute 201, a positioning plate 202, a round rod slide rail 203, a lever 204, a buckle 205 and a spring 206; two round rod slide rails 203 are fixed on the upper plate 105, and a positioning plate 202 is slidably installed on the round rod slide rails 203, one of which is sleeved with a spring 206, and the spring 206 is arranged between the positioning plate 202 and the fixed small plate of the upper plate 105, and the buckle 205 is installed on the small column of the upper plate 105, and the head of the buckle 205 is stuck on the side of the positioning plate 202, and the tail of the buckle 205 is connected to the fixed small plate of the upper plate 105 through a spring, and the upper part of the two vertical poles 104 is fixed with a feeding chute 201, and one side of the feeding chute 201 is fixed on the vertical pole 104, and the other side is fixed above the vertical plate A102;

[0033] When the fully automatic intermittent feeding mechanism 2 is in use, the copper ingots slide down the feeding chute 201 in an orderly manner, and the first copper ingot slides onto the positioning plate 202. The lever 204 rotates clockwise under the drive of the stepper motor 401, and the short rod on the lever 204 touches the buckle 205 first, and the buckle 205 rotates to disengage from the positioning plate 202. The positioning plate 202 slides under the elastic force of the spring 206 until the round hole on the positioning plate 202 slides under the copper ingot, and the copper ingot falls into the variable electromagnetic induction heating mechanism 3 through the round hole. While the positioning plate 202 slides, The side plates on the positioning plate 202 will catch the next copper ingot and prevent it from sliding down. When the first copper ingot falls down, the lever 204 continues to rotate, and the long rod on the lever 204 moves the positioning plate 202, thereby driving the positioning plate 202 to reset until the buckle 205 clamps the positioning plate 202 again. At the same time of resetting, the side plates on the positioning plate 202 are separated from the feeding chute 201, so that the copper ingot slides down; when the copper ingot in the variable electromagnetic induction heating mechanism 3 is heated and conveyed out, the lever 204 rotates clockwise again to convey the next copper ingot.

[0034] Examples, such as Figures 6-8As shown in the figure, the variable electromagnetic induction heating mechanism 3 includes: a motor 301, a gear 302, a shaft C 303, a pinion gear 304, a turntable 305, a base 306, an upper turntable 307, a lower clamping plate 308, an upper clamping plate 309, a shrapnel 310, a switch 311, an electric cylinder 312, a cylinder 313, an electromagnetic coil 314, and an extended electromagnetic coil 315; The motor 301 is fixed below the bottom support frame 101. The gear on the shaft of the motor 301 meshes with the gear 302. The gear 302 is fixedly installed on the shaft C 303. The shaft C 303 is rotatably installed in the through holes of the bottom support frame 101 and the upper layer plate 105. A pinion gear 304 is fixed on the shaft C 303. The pinion gear 304 meshes with the teeth on the turntable 305. The turntable 305 is rotatably installed in the base 306. The lower clamping plate 308 is slidably installed in the chute of the base 306. And the small column on the lower clamping plate 308 is fixed in the chute of the turntable 305. Four cylinders 313 are fixed on the lower clamping plate 308 and the turntable 305. The upper part of the cylinder 313 is fixed to the upper turntable 307. The small column on the upper clamping plate 309 is fixed in the chute of the turntable 307. The upper clamping plate 309 is connected to the shrapnel 310. The shrapnel 310 is placed in the electromagnetic coil 314. A wire is provided on the electromagnetic coil 314 and is connected to the switch 311. An electric cylinder 312 is also fixedly installed on the base 306. The other end of the electric cylinder 312 is connected to the extended electromagnetic coil 315. The upper turntable 307 is fixed between the limit block A 106 and the limit block B 107;

[0035] When the copper ingot drops onto the variable electromagnetic induction heating mechanism 3, the dropped copper ingot will drop to the center of the electromagnetic coil 314 under the action of the shrapnel 310, thus ensuring uniform heating. The variable electromagnetic induction heating mechanism 3 can change the diameter of the electromagnetic coil 314 to adapt to copper ingots of different sizes. Specifically, when the diameter becomes smaller, the pinion gear 304 rotates driven by the motor 301, thereby driving the turntable 305 to rotate. The turntable 305 drives the upper turntable 307 to rotate. The chutes on the turntable 305 and the upper turntable 307 drive the lower clamping plate 307 and the upper clamping plate 308 to slide inward, thereby driving the electromagnetic coil 314 to contract, making the four electromagnetic coils 314 butt against each other, thus reducing the diameter of the electromagnetic coil 314 to heat copper ingots of smaller sizes. Before the upper clamping plate 307 and the lower clamping plate 308 slide inward, the electric cylinder 312 starts, driving the extended electromagnetic coil 315 to move outward, thus providing a space for the contraction of the electromagnetic coil 314.

[0036] Example, as Figure 9 As shown in the figure, the fully automatic intermittent feeding mechanism 4 includes: a stepper motor 401, a driven gear 402, a semi-tooth gear 403, a sector gear 404, a torsion spring 405, and a feeding chute 406; Shaft A 5

[0037] A semi-toothed gear 403 is fixedly installed in the middle, and a driven gear 402 is fixedly installed at the lower end. The driven gear 402 meshes with the gear on the stepper motor 401. The stepper motor 401 is fixed on the vertical plate A102. A sector-shaped clamping plate 404 is rotatably installed in the middle of the shaft B6. The teeth on the sector-shaped clamping plate 404 can mesh with the teeth of the semi-toothed gear 403. A torsion spring 405 is also sleeved on the shaft B6. The torsion spring 405 is arranged below the sector-shaped clamping plate 404, with one end stuck on the small column of the sector-shaped clamping plate 404 and the other end stuck on the vertical plate B103.

[0038] After the copper ingot is heated, the stepper motor 401 drives the driven gear 402 to rotate, thereby driving the semi-toothed gear 403 to rotate. The semi-toothed gear 403 drives the sector-shaped clamping plate 404 to rotate. When the circular hole on the sector-shaped clamping plate 404 aligns with the circular hole on the base 306, the copper ingot drops into the blanking chute 406, so that the copper ingot is output. When the teeth of the semi-toothed gear 403 are disengaged from the teeth on the sector-shaped clamping plate 404, the sector-shaped clamping plate 404 resets under the action of the torsion spring 405. The semi-toothed gear 403 and the lever 204 are both fixedly installed on the shaft A5. That is, when the shaft A5 rotates one circle, the blanking and loading of one process are completed, with blanking first and then loading.
