Description

Technical Field

[0001] The present application relates to the field of conveying technology, and in particular to a transfer and conveying device for metal parts. Background Art

[0034] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0036] Embodiment 1:

[0037] In the high-temperature quenching operation of metal parts, the metal parts to be quenched need to be placed in a box-type electric furnace, and then the box-type electric furnace is started for quenching, and the quenching temperature is maintained at about 900°C;

[0038] After the quenching of the metal parts is completed, the metal parts need to be placed in the quenching oil tank for cooling. In this embodiment, the distance between the box-type electric furnace and the quenching oil tank is four meters. In order to ensure the heat treatment quality of the metal parts, the metal parts need to be transferred from the box-type electric furnace to the quenching oil tank within 15 seconds;

[0039] In order to achieve the above-mentioned rapid transfer, Figure 1 As shown, the present application provides a transfer and conveying device for metal parts, including a conveying frame 1, and a conveying assembly 2 is arranged on the conveying frame 1, and the conveying assembly 2 is used to transport metal parts;

[0040] The conveying assembly 2 includes a conveying motor 21 fixedly mounted on the conveying frame 1, and a driving sprocket (not shown in the figure) is fixedly mounted on the output end of the conveying motor 21, and the driving sprocket is rotatably mounted on the conveying frame 1, so that the driving sprocket can rotate on the conveying frame 1 under the drive of the conveying motor 21, and a driven sprocket 23 is rotatably mounted on the end of the conveying frame 1 away from the driving sprocket, and a chain plate 22 is transmission-arranged on the driving sprocket and the driven sprocket 23 to facilitate the placement of metal parts, and driven by the driving sprocket, the driven sprocket 23 is driven to rotate through the chain plate 22, and the metal parts on the chain plate 22 are transported;

[0041] For the convenience of explanation, the end of the conveyor frame 1 close to the driving sprocket is defined as the starting end, and the end of the conveyor frame 1 close to the driven sprocket 23 is defined as the discharging end. Driven by the conveying motor 21, the driving sprocket drives the driven sprocket 23 to rotate through the chain plate 22 to form a conveying line for conveying metal, so as to convey the metal parts carried by the chain plate 22 from the starting end to the discharging end.

[0042] In order to facilitate the grabbing of metal pieces in the box-type electric furnace, a first manipulator (not shown in the figure) is provided at the initial end of the conveyor frame 1, and in order to grab the metal pieces on the chain plate 22, a second manipulator (not shown in the figure) is provided at the discharge end of the conveyor frame 1;

[0043] It can be understood that during transportation, the box-type electric furnace is opened, the first manipulator grabs the metal piece after heat treatment in the box-type electric furnace, and places it on the chain plate 22 at the initial end of the conveying frame 1. Driven by the conveying motor 21, the chain plate 22 transports the carried metal piece from the starting end to the discharge end. When the metal piece is at the discharge end, the second manipulator grabs the metal piece and puts it into the quenching oil tank for treatment, and the length of the conveying frame 1 is 4 meters, so that the time for grabbing the metal piece from the box-type electric furnace and transporting it to the quenching oil tank is 15 seconds;

[0044] In order to control the discharge speed of metal parts according to the actual quenching conditions, such as Figure 1-Figure 4 As shown, a blocking component 3 is provided at the discharge end of the conveying frame 1, and the blocking component 3 is used to block and release the metal parts to adjust the conveying time of the metal parts;

[0045] The blocking assembly 3 includes a bottom plate 31 fixedly mounted on one side of the discharge end of the conveying frame 1, a mounting frame 32 fixedly arranged on the bottom plate 31, and a servo motor 35 fixedly arranged on the mounting frame 32, and a rotating shaft (not shown in the figure) fixedly mounted on the output end of the servo motor 35, and a first synchronous wheel 36 fixedly sleeved on the rotating shaft, so that the first synchronous wheel 36 can rotate under the drive of the servo motor 35;

[0046] like Figure 5As shown, a rotating rod 39 is rotatably mounted on the conveying frame 1, a rotating plate 33 is fixedly mounted on the rotating rod 39, and a side plate 310 is fixedly mounted on the conveying frame 1, so that the rotating plate 33 can move closer to or away from the side plate 310 along the rotating rod 39;

[0047] At the same time, a round rod (not shown in the figure) is installed on the bearing of one end of the rotating plate 33 away from the rotating rod 39, and a second synchronous wheel 38 is fixedly sleeved on the round rod, and a first chain 37 is transmitted and arranged on the second synchronous wheel 38 and the first synchronous wheel 36, so that the second synchronous wheel 38 can be driven to rotate through the first synchronous wheel 36 and the first chain 37, and when the rotating plate 33 approaches or moves away from the side plate 310, the chain drives the first chain 37 to approach or move away from the side plate 310;

[0048] Continue to refer Figure 2 At the same time, a spring 34 is provided on the bottom of the rotating plate 33 and the conveying frame 1. The spring 34 has a certain elastic force to support the rotating plate 33;

[0049] It should be noted that, in the initial state, the rotating plate 33 is tilted on the conveying frame 1 under the action of the spring 34, and forms a certain angle with the advancing direction of the chain plate 22, so that the first chain 37 is in an inclined state, and forms an inclined channel with the side plate 310, the width of which gradually decreases along the conveying direction of the metal piece, and the maximum width of the inclined channel is the same as the width of the chain plate 22, while the minimum width of the inclined channel is smaller than the diameter of the metal piece, so that in the initial state, the inclined channel can guide the metal piece through the maximum width position, and has a certain blocking effect on the metal piece through the minimum width position;

[0050] In summary, when conveying metal pieces, the metal pieces are first placed at the starting end of the chain plate 22, and then conveyed to the discharge end through the transmission of the chain plate 22;

[0051] When the metal piece reaches the position of the blocking assembly 3, it is introduced through the maximum width of the inclined channel and finally stops in the inclined channel, so that the conveying of the metal piece can be suspended to adjust the conveying time of the metal piece, and the position where the metal piece finally stops is in contact with both the side plate 310 and the first chain 37;

[0052] When the metal piece needs to be conveyed to the quenching oil tank, the servo motor 35 is started. Driven by the servo motor 35, the first chain 37 rotates cyclically. At this time, the metal piece generates friction due to the rotation of the first chain 37, which helps drive it to move forward in close contact with the side plate 310 on the chain plate 22, and squeezes the spring 34, so that the rotating plate 33 rotates away from the side plate 310, thereby increasing the minimum width of the inclined channel until the minimum width of the inclined channel is greater than the diameter of the metal piece. The metal piece can smoothly pass through the inclined channel and reach the position of the quenching oil tank;

[0053] After the metal piece passes through the inclined channel, the metal piece no longer presses the first chain 37. At this time, under the action of the spring 34, the rotating plate 33 returns to the initial state, thereby driving the first chain 37 to reset.

[0054] At the same time, a pushing component 4 is provided on the blocking component 3, and the pushing component 4 is used to push the rotating plate 33 to swing, so as to facilitate the metal piece to pass through the inclined channel smoothly;

[0055] like Figure 2 , Figure 4 and Figure 6 As shown, the pushing assembly 4 includes a fixed plate 41 fixedly mounted on the bottom plate 31, and a straight rod 44 is rotatably mounted on the fixed plate 41. A third synchronous wheel 42 is fixedly sleeved on the straight rod 44 and the rotating shaft, and a second chain 43 is transmission-set on two sets of the third synchronous wheels 42, so that when the servo motor 35 rotates, the rotating shaft drives the straight rod 44 to rotate through the third synchronous wheel 42 and the second chain 43;

[0056] At the same time, a disc 45 is fixedly installed at one end of the straight rod 44 away from the third synchronous wheel 42, and a fixing rod 47 is arranged at the bottom of the disc 45 away from the center of the circle, so that the disc 45 is driven by the straight rod 44 to drive the fixing rod 47 to rotate, and at the same time, a swing rack 46 is rotatably installed on the fixing plate 41;

[0057] It should be noted that one end of the swing rack 46 has a sliding end, and a sliding groove (not shown in the figure) adapted to the fixed rod 47 is opened on the sliding end, and the fixed rod 47 is located inside the sliding groove. At this time, during the rotation process, the fixed rod 47 synchronously moves in the sliding groove from the end of the sliding groove close to the center of the disk 45 to the end of the disk 45 away from the center of the circle, and slides in a reciprocating manner, thereby driving the swing rack 46 to reciprocate along the rotation point between it and the fixed plate 41;

[0058] At the same time, a fan-shaped end is provided on the side of the swing rack 46 away from the sliding end, and the fan-shaped end has a plurality of groups of fan-shaped arranged latching teeth, and a slide bar 48 is slidably provided on the fixed plate 41, and a meshing tooth 49 meshing with the latching tooth is provided on the slide bar 48. Therefore, when the sliding end is driven by the fixed rod 47 to reciprocate, the latching tooth of the fan-shaped end is driven to swing back and forth, and a continuous bite and separation action is generated with the meshing tooth 49. This bite and separation process further converts the swinging motion of the swing rack 46 into a linear reciprocating motion of the slide bar 48, thereby driving the slide bar 48 to reciprocate on the fixed plate 41. Extend and retract;

[0059] It should be noted that when the slide bar 48 is extended, the slide bar 48 will contact the rotating plate 33 and drive the rotating plate 33 to rotate along the axis of the rotating rod 39 in the direction close to the side plate 310, so as to resist the metal piece and make it stay on the chain plate 22 for a period of time, so as to control the time of transportation of the metal piece;

[0060] In the present application, since the metal parts are in a high-temperature state, the positions on the conveying component 2 that are in contact with the metal parts are all made of high-temperature resistant metal materials to extend the life of the conveying component 2.

[0061] Embodiment 2:

[0062] Although the blocking assembly 3 can make the metal pieces pass through the inclined channel in an orderly manner, when there are many metal pieces piled up in the inclined channel, the multiple groups of metal pieces will still contact each other. Therefore, when the metal pieces are led out of the inclined channel, more than one metal piece may pass through the inclined channel, resulting in insufficient time for the metal pieces to enter the quenching oil tank.

[0063] In order to solve this problem, a spacing component 5 is provided on the blocking component 3 to reserve enough time for the metal parts to enter the quenching oil tank. The spacing component 5 is used to space multiple groups of contacting metal parts.

[0064] like Figure 2 and Figure 7 As shown, the spacing assembly 5 includes a fixed block 52 fixedly arranged on the mounting frame 32, and a gear 55 is rotatably mounted on the fixed block 52. At the same time, a connecting block 53 is fixedly mounted on the rotating plate 33, and an arc-shaped rack 54 is fixedly mounted on one end of the connecting block 53 away from the rotating plate 33. The arc-shaped rack 54 is meshed and connected with the lower teeth of the gear 55 to form a closely connected transmission unit, so that when the rotating plate 33 rotates, the arc-shaped rack 54 can be driven to rotate synchronously through the connecting block 53, thereby driving the gear 55 to rotate;

[0065] At the same time, a transmission rack 56 is slidably arranged on the fixed block 52, and the transmission rack 56 is meshed with the upper teeth of the gear 55. In order to prevent the transmission rack 56 from falling out of the fixed block 52 under the action of gravity, protrusions (not shown in the figure) with the same length as the transmission rack 56 are fixedly arranged on both sides of the transmission rack 56, and the protrusions are slidably arranged inside the fixed block 52 to limit the transmission rack 56;

[0066] An insert 51 for spacing multiple groups of metal parts in contact with each other is fixedly installed at one end of the transmission rack 56, so that when the gear 55 rotates, the transmission rack 56 can be driven to move smoothly on the fixed block 52, thereby driving the insert 51 to extend or retract, so as to separate and release the multiple groups of metal parts in contact with each other;

[0067] In summary, in the initial state, the rotating plate 33 is tilted on the conveying frame 1 under the action of the spring 34, and the transmission rack 56 is retracted into the interior of the fixed block 52;

[0068] When a group of metal parts need to pass through the inclined channel, the rotating plate 33 will be squeezed to rotate in a direction away from the side plate 310. When the rotating plate 33 rotates, the arc-shaped rack 54 will be driven to rotate synchronously, thereby driving the gear 55 to rotate.

[0069] During the rotation of the gear 55, the transmission rack 56 is driven to slide on the fixed block 52, thereby driving the insert 51 to extend and be located between the two sets of metal parts, so that the subsequent metal parts can be blocked at intervals to prevent multiple sets of metal parts from passing through at one time;

[0070] When a single group of metal pieces passes through the inclined channel, the rotating plate 33 will be reset under the action of the spring 34, and drive the inserting piece 51 to reset and retract into the interior of the fixed block 52 to open the channel for subsequent metal piece conveying.

[0071] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
