Technical Field
[0001] The present application relates to the field of spring production technology, and in particular to a discharge sorting device for a spring tempering furnace. Background Art
[0002] The tempering furnace is used for tempering general metal parts in air, as well as quenching, annealing, and aging heat treatment of light alloy parts such as aluminum alloy die castings, pistons, and aluminum plates. During the production of springs, in order to improve the toughness and plasticity of the springs, it is necessary to temper the quenched springs, and the springs are transported to the tempering furnace for tempering.
[0003] In order to improve production efficiency, generally, two springs of different sizes with the same tempering process can be transported to the same tempering furnace for tempering. However, the two springs of different sizes will be mixed together after being output from the tempering furnace, which is inconvenient for the subsequent processing of the two springs. Summary of the invention
[0004] In order to classify two springs of different sizes when they are output from a tempering furnace to facilitate the subsequent processing of the two springs, the present application provides a discharge sorting device for a spring tempering furnace.
[0005] The present application provides a discharging and sorting device for a spring tempering furnace, which adopts the following technical solution:
[0006] A discharge sorting device for a spring tempering furnace comprises a conveying pipe, a first collecting box and a second collecting box, the first collecting box and the second collecting box both having openings on the top, the first collecting box being located at one side of the second collecting box, one end of the conveying pipe being used to communicate with the discharge port of the tempering furnace, a rotating plate being rotatably arranged below the conveying pipe, the bottom of the rotating plate being rotatably connected to the side wall of the first collecting box or the side wall of the second collecting box, one end of the rotating plate along the length direction being located above the first collecting box, the other end of the rotating plate being located above the second collecting box, the end of the rotating plate located above the first collecting box being higher than the end thereof located above the second collecting box, the other end of the conveying pipe facing the end of the rotating plate located above the first collecting box, an elastic member being connected to the bottom of the rotating plate, the elastic member being used to reset the rotating plate.
[0007] By adopting the above technical scheme, two springs of different sizes enter the conveying pipe when being output from the discharge port of the tempering furnace. When the conveying pipe outputs a smaller spring, the smaller spring falls to the higher end of the rotating plate. Since the smaller spring has a smaller mass, the smaller spring can slide along the rotating plate to the second collection box for collection; when the conveying pipe outputs a larger spring, the larger spring falls to the higher end of the rotating plate. Since the larger spring has a larger mass, the larger spring presses down the higher end of the rotating plate, the elastic member is deformed and compressed, and the higher end of the rotating plate opens toward the top of the first collection box. The larger spring slides from the rotating plate to the first collection box for collection, and the elastic member is deformed and reset, and the rotating plate can be reset, so that the upper end of the first collection box can be higher than its upper end of the second collection box. In this way, the two springs of different sizes output from the tempering furnace can be classified, and the later processing of the two springs can be facilitated.
[0008] Preferably, a switch component for opening and closing the end opening of the conveying pipe is provided at one end of the conveying pipe close to the rotating plate, and the inner wall of the first collecting box and the inner wall of the second collecting box are both connected to a first detection component, and the first detection component is electrically connected to a controller. The first detection component is used to detect the spring entering the first collecting box or the second collecting box and output a feeding signal, and the controller is used to receive the feeding signal and control the switch component to open the end opening of the conveying pipe.
[0009] By adopting the above technical solution, when the first detection member detects that a spring has entered the first collection box or the second collection box, the controller controls the switch member to open the opening at the end of the delivery tube to output the next spring, which can avoid multiple springs from being delivered to the rotating plate as much as possible. In this way, there can be at most one spring on the rotating plate, which can avoid the rotating plate from rotating due to multiple springs as much as possible, and can improve the accuracy of spring classification.
[0010] Preferably, it also includes a second detection member, which is electrically connected to the controller, and is used to detect the spring output from the end opening of the conveying pipe and output a discharge signal. The controller is used to receive the discharge signal and control the switch member to close the end opening of the conveying pipe.
[0011] By adopting the above technical solution, when the second detection member detects that a spring is output from the opening at the end of the delivery tube, the controller controls the switch member to close the opening at the end of the delivery tube to stop outputting the next spring, so that the delivery tube can output only one spring at a time, and multiple springs can be avoided as much as possible from being delivered to the rotating plate. Until the first detection member detects that the spring enters the first collection box or the second collection box, the controller controls the switch member to open the opening at the end of the delivery tube to output the next spring, so that the rotating plate can classify only one spring at a time, which can improve the accuracy of spring classification.
[0012] Preferably, a plurality of convex strips are distributed on the inner circumferential wall at the bottom of the conveying pipe, and the convex strips are evenly spaced along the length direction of the conveying pipe, and the length direction of the convex strips is distributed circumferentially along the conveying pipe. A vibrator is connected to the outer circumferential wall of the conveying pipe, and the vibrator is electrically connected to the controller. The controller is used to receive a feed signal and control the vibration of the vibrator.
[0013] By adopting the above technical solution, after the two springs of different sizes are conveyed into the conveying pipe, the convex strips can limit the springs. When the springs enter the first collection box or the second collection box, the controller controls the switch to open the opening at the end of the conveying pipe, and controls the vibrator to vibrate the conveying pipe. The vibrator can vibrate the spring out of the conveying pipe, and can avoid multiple springs being output from the conveying pipe as much as possible, so that the conveying pipe can output at most one spring at a time.
[0014] Preferably, the inner bottom wall of the first collection box is slidably connected with a first sliding block, and the first sliding block is slidably connected to the inner bottom wall of the first collection box along the width direction of the bottom wall of the first collection box through a first driving member;
[0015] The inner bottom wall of the second collection box is slidably connected with a second sliding block, and the second sliding block is slidably connected to the inner bottom wall of the second collection box along the width direction of the bottom wall of the second collection box through a second driving member.
[0016] By adopting the above technical solution, when the springs are collected in the first collection box, the first sliding block can slide on the bottom wall of the first collection box to drive the springs to move, so that the springs can be neatly placed at the bottom of the first collection box; when the springs are collected in the second collection box, the second sliding block can slide on the bottom wall of the second collection box to drive the springs to move, so that the springs can be neatly placed at the bottom of the second collection box, thereby increasing the spring collection amount of the first collection box and the second collection box.
[0017] Preferably, the first driving member and the second driving member are both electrically connected to the controller, and the top of the first sliding block and the top of the second sliding block are both connected to a third detection member, and the third detection member is electrically connected to the controller. The third detection member is used to detect the pressure of the spring and output a pressure signal, and the controller is used to receive the pressure signal and convert it into a pressure value for comparison with the pressure value corresponding to the pressure signal received last time. When the difference between the two pressure values is greater than a preset value, the controller controls the first driving member to drive the first sliding block to slide or controls the second driving member to drive the second sliding block to slide.
[0018] By adopting the above technical solution, after the spring is collected in the first collection box, the controller compares the pressure values corresponding to the two pressure signals output by the third detection member before and after in the first collection box. When the difference between the two pressure values is greater than the preset value, the controller can determine that a spring has entered the first collection box. The controller controls the first driving member to drive the first sliding block to slide, so that the spring can be neatly placed at the bottom of the first collection box. Similarly, the spring can be neatly placed at the bottom of the second collection box.
[0019] Preferably, a first sliding groove is provided in the inner bottom wall of the first collecting box along the width direction, a first connecting block is slidingly connected in the first sliding groove, the first connecting block is connected to the first sliding block, a first spring is provided in the first sliding groove, one end of the first spring is connected to the first sliding block, and the other end of the first spring is connected to the end wall of the first sliding groove, the first driving member is a first cylinder, and the piston rod of the first cylinder passes through the end wall of the first sliding groove and is connected to the first connecting block;
[0020] A second sliding groove is opened in the inner bottom wall of the second collecting box along the width direction, a second connecting block is slidingly connected in the second sliding groove, the second connecting block is connected to the second sliding block, a second spring is provided in the second sliding groove, one end of the second spring is connected to the second sliding block, the other end of the second spring is connected to the end wall of the second sliding groove, the second driving member adopts a second cylinder, the piston rod of the second cylinder passes through the end wall of the second sliding groove and is connected to the second connecting block.
[0021] By adopting the above technical scheme, when the controller controls the first cylinder to drive the first sliding block to slide, the piston rod of the first cylinder pushes the first connecting block. When the first connecting block drives the first sliding block to slide, the first spring deforms and stretches. When the piston rod of the first cylinder retracts, the first spring deforms and resets, and the first connecting block can be pulled back. When the first connecting block is pulled back by the first spring, the first spring can be squeezed due to inertia, and the first spring can push the first connecting block again through elastic potential energy. In this way, after the piston rod of the first cylinder pushes the first connecting block once, the piston rod of the first cylinder retracts, and the first connecting block moves back and forth multiple times. When the first connecting block reciprocates and drives the first sliding block to slide, it can have a vibration effect, thereby improving the efficiency of the first sliding block driving the spring to move. Similarly, the efficiency of the second sliding block driving the spring to move can be improved, thereby increasing the spring collection amount of the first collection box and the second collection box.
[0022] Preferably, a plurality of spring grooves are provided at the top of the side wall of the first collection box, and the spring grooves are evenly spaced along the width direction of the rotating plate. The elastic member is a torsion spring, and the torsion spring is located in the spring groove, and one end of the torsion spring abuts against the bottom of the rotating plate, and the other end of the torsion spring abuts against the side wall of the first collection box.
[0023] By adopting the above technical solution, the operator can install each torsion spring in each spring slot. When the rotating plate is pressed down and rotated by the spring, the torsion spring is deformed. After the spring is detached from the rotating plate, the torsion spring recovers, which can make the rotating plate rotate and reset so that the rotating plate can classify the next spring.
[0024] Preferably, both end walls of the spring groove are connected to a limiting rod, the length direction of the limiting rod is consistent with the width direction of the rotating plate, one end of the limiting rod is located in the spring groove, the end of the limiting rod is connected to a locking block for limiting the torsion spring, the limiting rod is provided with an inner cavity, one end of the locking block is located in the inner cavity, and the other end of the locking block protrudes out of the outer peripheral wall of the limiting rod, and the locking block is slidably connected to the limiting rod to realize that the locking block protrudes out of the outer peripheral wall of the limiting rod or is located in the inner cavity.
[0025] By adopting the above technical solution, when the operator installs the torsion spring in the spring groove, the two ends of the torsion spring are respectively mounted on the two end portions of the limit rods in the spring groove and connected to the two locking block ends protruding from the outer peripheral wall of the limit rod, so that the spring can be limited in the spring groove. When one end of the two locking blocks protruding from the outer peripheral wall of the limit rod slides into the inner cavity, the operator can compress the torsion spring to remove the torsion spring from between the two limit rod ends, so that the torsion spring can be disassembled. After the operator has taken out part of the torsion spring in the spring groove, the rotation amplitude of the rotating plate can be adjusted.
[0026] Preferably, a plurality of give way grooves are provided on the top of the side wall of the first collection box, and each of the give way grooves is respectively located on both sides of each of the spring grooves, and the limit rod is slidably connected to a locking rod, and the length direction of the locking rod is consistent with the length direction of the limit rod, one end of the locking rod is located in the give way groove, and the other end of the locking rod is located in the inner cavity after passing through the end wall of the give way groove, and a third spring is provided in the inner cavity, one end of the third spring is connected to the end of the locking rod, and the other end of the third spring is connected to the inner wall of the end of the limit rod, and the other end of the locking rod passes through the end of the limit rod away from the third spring, and a fourth spring is connected to the side wall of the locking rod, and one end of the fourth spring is connected to one end of the locking block located in the inner cavity.
[0027] By adopting the above technical solution, the operator can press the locking rod in the yield groove to make the locking rod slide into the inner cavity. The end of the locking rod located in the inner cavity squeezes the third spring. When the locking rod slides, it pulls the fourth spring, and the fourth spring drives the locking block to slide into the inner cavity, so that the end of the locking block protruding from the outer peripheral wall of the limit rod can slide into the inner cavity. After the operator releases the locking rod, the third spring deforms and resets, and the locking rod can be pushed out of the inner cavity. When the locking rod moves, the fourth spring deforms and resets, and one end of the locking block can be pushed out of the inner cavity, which makes it convenient for the operator to install or remove the torsion spring in the spring groove.
[0028] In summary, the present application includes at least one of the following beneficial technical effects:
[0029] 1. Two springs of different sizes enter the conveying pipe when being discharged from the discharge port of the tempering furnace. When the conveying pipe outputs a smaller spring, the smaller spring falls to the higher end of the rotating plate. Since the smaller spring has a smaller mass, the smaller spring can slide along the rotating plate to the second collection box for collection; when the conveying pipe outputs a larger spring, the larger spring falls to the higher end of the rotating plate. Since the larger spring has a larger mass, the larger spring presses down the higher end of the rotating plate, the elastic member is deformed and compressed, and the higher end of the rotating plate opens toward the top of the first collection box. The larger spring slides from the rotating plate to the first collection box for collection, the elastic member is deformed and reset, and the rotating plate can be reset, so that the upper end of the first collection box can be higher than its upper end of the second collection box, so that the two springs of different sizes output from the tempering furnace can be classified, and the later processing of the two springs can be facilitated;

After the springs are collected in the first collection box, the first sliding block can slide on the bottom wall of the first collection box to drive the springs to move, so that the springs can be neatly placed at the bottom of the first collection box; when the springs are collected in the second collection box, the second sliding block can slide on the bottom wall of the second collection box to drive the springs to move, so that the springs can be neatly placed at the bottom of the second collection box, thereby increasing the spring collection capacity of the first collection box and the second collection box.

[0061] The implementation principle of the discharge sorting device of a spring tempering furnace in an embodiment of the present application is as follows: the spring enters the conveying pipe 200 from the tempering furnace 100, the controller controls the vibrating member 203 to vibrate the conveying pipe 200, the spring is vibrated to the opening at the end of the conveying pipe 200, the controller controls the switch member 201 to open the opening at the end of the conveying pipe 200, the spring is output from the conveying pipe 200, the second detection member detects the spring output, and the controller controls the switch member 201 to close the opening at the end of the conveying pipe 200.
[0062] The spring is transported to the rotating plate 500. When the delivery pipe 200 outputs a spring with a large mass, the spring presses down the higher end of the rotating plate 500. The rotating plate 500 rotates, and the spring with a large mass slides along the rotating plate 500 to be collected in the first collecting box 300. The rotating plate 500 is reset, and the first detection member detects that a spring has entered the first collecting box 300. The controller controls the vibration member 203 to vibrate and controls the switch member 201 to open the opening at the end of the delivery pipe 200.
[0063] When the delivery pipe 200 outputs a spring of small mass, the spring slides along the rotating plate 500 into the second collection box 400, the first detection member detects that the spring has entered the second collection box 400, and the controller controls the vibration member 203 to vibrate and controls the switch member 201 to open the end opening of the delivery pipe 200. In this way, the two springs of different sizes output from the tempering furnace 100 can be classified, and the later processing of the two springs can be facilitated.
[0064] When the spring enters the first collection box 300 or the second collection box 400, the spring presses down the first sliding block 301 or the second sliding block 401, and the third detection member transmits a pressure signal to the controller. The controller compares the pressure values corresponding to the two pressure signals successively transmitted by the third detection member, and compares the difference between the two pressure values with the preset value. When the difference is greater than the preset value, the controller determines that a spring has entered the first collection box 300 or the second collection box 400, and the controller controls the first driving member 302 to drive the first sliding block 301 to slide or controls the second driving member 402 to drive the second sliding block 401 to slide.
[0065] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
