Description

Technical Field

[0001] The invention belongs to the technical field of heating furnace equipment, in particular to a discharge device for a medium frequency heating furnace. Background Art

[0002] A medium frequency furnace is a device that changes direct current into an adjustable medium frequency current, and then supplies medium frequency alternating current to flow through capacitors and induction coils, thereby generating high-density magnetic lines of force in the induction coil, and then the metal in the induction coil can be heated by these magnetic lines of force. After the metal is heated, plasticity and other operations can be performed. The columnar metal is placed on the discharge device in the through-type medium frequency heating furnace, and the columnar metal is driven through the medium frequency heating furnace by the discharge device to be heated before being discharged.

When in use, the mounting plates at both ends of the guide rail are replaced with spring mounting plates in the red part. After thermal expansion and contraction, the movable spring can move freely according to the lateral deformation of the guide rail, avoiding the generation of cracks caused by force conflict during the previous fixation, and the solid guide rail has a longer service life.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] Embodiment 1: Figures 1 to 7 As shown, the embodiment of the present invention provides a discharge device for a medium frequency heating furnace, comprising a mounting shell 1, a driving mechanism 2 is arranged in the inner cavity of the mounting shell 1, cleaning mechanisms 3 are arranged on both sides of the inner cavity of the mounting shell 1, and a discharge mechanism 4 is arranged in the middle of the inner cavity of the mounting shell 1;

[0030] The driving mechanism 2 includes a motor 21, which is fixedly connected to the outside of the mounting shell 1, and the output shaft of the motor 21 is fixedly sleeved with a bidirectional lead screw 22, and the surface of the bidirectional lead screw 22 is meshed with a mounting ring 24, and the side of the mounting ring 24 away from the bidirectional lead screw 22 is fixedly connected to a C-shaped frame 25, and the upper and lower ends of the C-shaped frame 25 close to the discharging mechanism 4 are fixedly connected to a motor 2 26;

[0031] The cleaning mechanism 3 includes a front wheel 31, which is arranged on the top of the C-shaped frame 25 on a side away from the motor 26, and the front wheel 31 is connected to the output shaft of the motor 26. A grinding belt 32 is sleeved on the surface of the front wheel 31, and a spring assembly 33 is fixedly connected to the side of the front wheel 31 away from the discharging mechanism 4. There are multiple spring assemblies 33, and the multiple spring assemblies 33 are respectively located at the upper and lower ends of the C-shaped frame 25. The inner cavity of the grinding belt 32 is sleeved with a rear wheel 34 and a driving wheel 35, and the rear wheel 34 is fixedly connected to an end of the spring assembly 33 located at the upper end of the C-shaped frame 25 away from the front wheel 31, and the driving wheel 35 is fixedly connected to an end of the spring assembly 33 located at the lower end of the C-shaped frame 25 away from the front wheel 31. The bottom end of the driving wheel 35 is fixedly connected to a driving rack 36, and a chip discharge port 6 is opened at the bottom of the mounting shell 1, and the chip discharge port 6 is located below the driving rack 36. The rear wheel 34 and the driving wheel 35 do not contact the C-shaped frame 25.

[0032] The front wheel 31 , the rear wheel 34 and the driving wheel 35 are all composed of a mounting frame 311 and a limiting wheel 312 . The limiting wheel 312 is movably connected to the inner cavity of the mounting frame 311 , and the mounting frame 311 is fixedly connected to the spring assembly 1 33 .

[0033] The tops of the left and right sides of the inner cavity of the mounting shell 1 are fixedly connected with spring components 7, the bottom of the spring components 7 is fixedly connected with a clamping frame 8, and the inner cavity of the clamping frame 8 is provided with an electric roller 9.

[0034] The bottom end of the inner cavity of the mounting shell 1 is fixedly connected with a guide rod 23, and the mounting ring 24 is provided with two connecting holes. The mounting ring 24 is respectively engaged with the surface of the bidirectional lead screw 22 and movably sleeved on the surface of the guide rod 23 through the two connecting holes.

[0035] A heating mechanism 5 is provided at the center of the inner cavity of the installation shell 1 . The heating mechanism 5 includes a medium frequency heating furnace 51 . The medium frequency heating furnace 51 is fixedly connected to both sides of the center of the installation shell 1 . The medium frequency heating furnace 51 includes an induction coil 52 .

[0036] In this embodiment, the columnar metal is first placed on the surface of the electric roller 1 44 above the support tube 1 41, and the electric roller 2 9 is pushed upward. After the electric roller 2 9 is pushed upward, the spring assembly 2 7 contracts and accumulates force to generate a reaction force, and the reaction force drives the electric roller 2 9 to squeeze the columnar metal. At this time, the columnar metal is located below two symmetrical electric rollers 2 9;

[0037] Then, the motor 1 21 is started to drive the bidirectional lead screw 22 to rotate. At this time, the bidirectional lead screw 22 and the mounting ring 24 are meshed, thereby driving the mounting ring 24 to move along the axial direction of the bidirectional lead screw 22 and the guide rod 23, thereby driving the C-shaped frame 25 to move toward the center of the mounting shell 1, so that the front wheels 31 on both sides move to the middle of the mounting shell 1 and contact, and at this time, the grinding belt 32 will bend and wrap around the outer surface of the columnar metal, and the grinding belt 32 will bend and deform, which will cause the length of the grinding belt 32 between the upper and lower front wheels 31 to increase, and the increased length is proportional to the thickness of the columnar metal (because the moving distance of the C-shaped frame 25 is fixed, while the thickness of the columnar metal is not fixed), and because the C-shaped frame 25 is located between the support tube 1 41 and the support tube 2 411, the grinding belt 32 can fit the outer surface of the columnar metal and will not be blocked by other objects;

[0038] Because in the above process, after the grinding belt 32 between the upper and lower front wheels 31 is blocked by the columnar metal, the length of this section of the grinding belt 32 will increase, causing the grinding belt 32 in other parts to shrink, pulling the rear wheel 34 and the driving wheel 35 to move in the direction of the front wheel 31, so that the spring assembly 1 33 shrinks and accumulates force, and the shrinkage distance of the spring assembly 1 33 is proportional to the thickness of the columnar metal. When the columnar metal is thicker, the shrinkage distance of the spring assembly 1 33 is longer, and the total length of the spring assembly 1 33 will decrease (coordinated with the increase in the length of the grinding belt 32 between the upper and lower front wheels 31), and the distance the rear wheel 34 and the driving wheel 35 move in the direction of the front wheel 31 is proportional to the thickness of the columnar metal;

[0039] Then, the electric roller 1 44 is started to drive the columnar metal to be transported in the direction of the induction coil 52, and the electric roller 2 9 is started to drive the columnar metal to rotate, and at the same time, the motor 2 26 is started to drive the limiting wheel 312 to rotate, thereby driving the grinding belt 32 to operate. The electric roller 2 9 drives the columnar metal to rotate, and the operation of the grinding belt 32 performs all-round slight grinding on the outer surface of the columnar metal, so that the metal debris and dust on the outer surface of the columnar metal are polished clean and discharged from the chip discharge port 6, thereby preventing the metal debris from being melted on the surface of the electric roller 1 44 by the heating mechanism 5, affecting the normal use of the electric roller 1 44, and also preventing the metal debris and dust from melting on the surface of the columnar metal when the columnar metal is heated, affecting the heating effect;

[0040] The columnar metal is driven to rotate by the electric roller 9, so that the columnar metal rotates when being ground by the grinding belt 32, further improving the uniformity of grinding. At the same time, the columnar metal rotates in the induction coil 52 to perform all-round uniform heating, thereby improving the heating effect.

[0041] Embodiment 2: Figure 1 , Figure 2 , Figure 3, Figure 4 , Figure 5 , Figure 7 As shown, the embodiment of the present invention provides a discharge device for a medium frequency heating furnace, the discharge mechanism 4 includes a support tube 1 41 and a support tube 2 411, the support tube 1 41 and the support tube 2 411 are both fixedly connected to the middle of the inner cavity of the mounting shell 1, the top ends of the support tube 1 41 and the support tube 2 411 are both fixedly connected to a support spring 42, the top ends of the support spring 42 are fixedly connected to a discharge rack 43, the bottom end of the discharge rack 43 is fixedly connected to a lower pull rod 49, and the lower pull rod 49 is located at the center of the inner cavity of the support spring 42 A wire take-up reel 45 is fixedly connected to the outer side of the support tube 41, and a rotating rod 47 is movably connected to the center of the wire take-up reel 45, and the rotating rod 47 passes through the wire take-up reel 45 and is fixedly connected to a gear 46, and a wire rope 48 is fixedly connected to the surface of the rotating rod 47, and a support frame 481 is fixedly connected to the bottom of the support tube 41, and the wire rope 48 fits with the support frame 481 and passes through the inner cavity of the support tube 41 and is fixedly connected to the bottom end of the lower pull rod 49, and the gear 46 is located on the moving path of the driving rack 36.

[0042] Both spring assembly 1 33 and spring assembly 2 7 are composed of a mounting spring 331 and a damping telescopic rod 332. The damping telescopic rod 332 is located at the center of the inner cavity of the mounting spring 331. The two ends of the mounting spring 331 and the damping telescopic rod 332 located at the mounting frame 311 are fixedly connected to the two mounting frames 311 respectively. The top and bottom ends of the mounting spring 331 and the damping telescopic rod 332 located at the clamping frame 8 are fixedly connected to the mounting shell 1 and the clamping frame 8 respectively.

[0043] A connecting plate 431 is fixedly connected to the bottom of the discharging rack 43 . There are a plurality of discharging racks 43 . The plurality of discharging racks 43 are respectively located above the supporting tube 1 41 and the supporting tube 2 411 . The plurality of discharging racks 43 are fixedly connected via the connecting plate 431 .

[0044] The C-shaped frame 25 is located between the support tube 1 41 and the support tube 2 411 , and the inner cavities of the plurality of discharging frames 43 are all provided with a motorized roller 1 44 .

[0045] In this embodiment, when the front wheels 31 on both sides contact the middle part of the mounting shell 1, the driving wheel 35 will also be driven to move. At this time, the grinding belt 32 is attached to the outer surface of the columnar metal and pulls the driving rack 36 at the bottom end of the driving wheel 35 to move, so that the driving rack 36 at the bottom end of the driving wheel 35 is meshed with the gear 46, and the gear 46 is driven to rotate with the movement of the driving rack 36. The rotation of the gear 46 drives the rotating rod 47 to rotate. The rotating rod 47 rotates and pulls the steel wire rope 48 to shrink toward the inner cavity of the wire take-up drum 45. At this time, the lower pull rod 49 is pulled downward by the steel wire rope 48, thereby adjusting the height of the electric roller 44 in the inner cavity of the discharge rack 43. Since all the discharge racks 43 are fixedly connected by the connecting plate 431, the height of all the electric rollers 44 can be adjusted.

[0046] Thus, after the columnar metal is placed on the electric roller 44, the thickness of the columnar metal can be determined by the grinding belt 32. When the thicker the columnar metal is placed on the electric roller 44, the greater the amplitude of the electric roller 44 being pulled down by the steel wire 48, so that the thicker columnar metal on the electric roller 44 is lowered to a greater extent, so that the columnar metal of this thickness is located in the middle of the induction coil 52, improving the uniformity of heating, and finally making the columnar metals of different thicknesses always keep the same distance from the induction coil 52, thereby avoiding the situation that the thinner columnar metal is far away from the induction coil 52, resulting in poor heating effect;

[0047] Then, the columnar metal is heated by the induction coil 52 , and the entire columnar metal is discharged from the mounting shell 1 one after another, and at the discharge point of the mounting shell 1 , it is also clamped and limited by the electric roller 2 9 .

[0048] Working principle and use process: first, place the columnar metal on the surface of the electric roller 44 above the support tube 41, then start the motor 21 to drive the bidirectional lead screw 22 to rotate, and through the rotation of the bidirectional lead screw 22, drive the mounting ring 24 meshing therewith to move along the axis direction of the bidirectional lead screw 22 and the guide rod 23 toward the center of the mounting shell 1, so that the C-shaped frame 25 drives the grinding belt 32 on the surface of the front wheel 31 to move toward the direction of the columnar metal, and makes the front wheels 31 on both sides of the support tube 41 contact at the center of the mounting shell 1, and then stop moving. At this time, the front wheel 31 is located at the gear 46. At this time, the grinding belt 32 will fit on both sides of the columnar metal to form a semi-wrapped state of the columnar metal. At this time, the length of the grinding belt 32 between the upper and lower front wheels 31 will increase due to the bending of the grinding belt 32, so that the grinding belt 32 will pull the rear wheel 34 and the driving wheel 35 in the direction of the front wheel 31, and the distance the rear wheel 34 and the driving wheel 35 are pulled is proportional to the size of the columnar metal;

[0049] At this time, the second motor 26 is started to drive the front wheel 31 to rotate, and the rotation of the front wheel 31 drives the grinding belt 32 to rotate, so as to slightly grind the surface of the columnar metal, so that the metal debris and dust on the surface are removed and fall to the chip discharge port 6, and then discharged through the chip discharge port 6;

[0050] When the driving wheel 35 is pulled toward the front wheel 31 by the grinding belt 32, the driving rack 36 is also driven to move toward the direction of the gear 46. At this time, the driving rack 36 is meshed with the gear 46. Since the grinding belt 32 pulls the driving wheel 35, the distance between the driving wheel 35 and the front wheel 31 is reduced, thereby driving the driving rack 36 to drive the gear 46 to rotate. The rotation of the gear 46 drives the rotating rod 47 to rotate. The rotating rod 47 drives the wire rope 48 to shrink toward the inner cavity of the take-up drum 45, thereby driving the wire rope 48 to pull the lower pull rod 49 downward, thereby driving the discharge rack 43 to descend, thereby driving the columnar metal on the electric roller 1 44 to descend, so that the columnar metals of different sizes always maintain the same distance from the induction coil 52;

[0051] Then, the columnar metal is transported toward the induction coil 52 by the electric roller 44, and the columnar metal is heated by the medium frequency heating furnace 51 and the induction coil 52;

[0052] After heating is completed, the material is discharged through the electric roller 44.

[0053] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
