Description

Technical Field

[0001] The utility model relates to the field of piston processing, in particular to an annealing device for piston processing. Background Art

[0002] Annealing is a metal heat treatment process, which refers to slowly heating the metal to a certain temperature, maintaining it for a sufficient time, and then cooling it at an appropriate rate. In a broad sense, annealing is a heat treatment process for materials, including metal materials and non-metallic materials. It can reduce their hardness, improve machinability, reduce residual stress, stabilize size, reduce deformation and crack tendency, and make the material structure and composition uniform. It can improve material properties or prepare for subsequent heat treatment. The piston is a reciprocating part in the cylinder block of a car engine. It must have sufficient strength and rigidity, and is also required to have good thermal conductivity, high temperature resistance, high pressure resistance, and corrosion resistance. For this reason, during the production process of the piston, the piston needs to be heat treated in order to increase its metal properties. Annealing is a commonly used piston heat treatment method, and an annealing device is generally used to anneal the piston.

[0003] The annealing device includes a feeding mechanism, a heating mechanism and a cooling mechanism. A pulling mechanism is also provided on the cooling mechanism for moving the cooled piston to the discharge port and then pushing and pulling it from the discharge port to the outside of the device. In the prior art, there are two ways to collect the piston pushed out from the discharge port. The first is to place a storage box under the discharge port of the annealing device, and the piston directly falls into the storage box. The second is to set a conveyor belt under the discharge port of the annealing device and convey it to a subsequent processing position through the conveyor belt. Both of these ways of collecting the piston have shortcomings. In the first way, the piston is prone to collision during collection. Even if the surface of the aluminum alloy piston is relatively hard, it is not completely invulnerable. If scratches or depressions are caused on the surface of the piston, the sealing performance of the piston will be affected. In the second way, since the piston is a columnar workpiece, it may roll on the conveyor belt, especially when the position where the equipment is placed is uneven and the conveyor belt is tilted, the columnar piston may roll on the conveyor belt in the direction opposite to the conveying direction, which is inconvenient for the transportation of the piston. In order to solve the above problems, an annealing device for piston processing is proposed. Utility Model Content

[0025] It also includes a material unloading component 6, which includes a driving unit and a material holding unit. The material holding unit is arranged at the driving end of the driving unit. The material holding unit includes a driving member 65 and a material holding member. The material holding member is arranged at the output end of the driving member 65. The driving member 65 is used to drive the material holding member to move along the length direction of the cooling member 5. The material holding member includes an insertion tube 69 and an airbag ring. The airbag ring includes an airbag 611. The airbag ring is sleeved on the outer wall of the insertion tube 69. The material holding member also includes an air pump 66. The output end of the air pump 66 is connected to the air inlet end of the airbag 611, which is used to inflate the airbag 611 to change the size of the airbag 611. The insertion tube 69 is used to carry the airbag ring deep into the piston. The airbag 611 abuts against the inner wall of the piston to hold the piston. The driving unit is used to drive the material holding unit to move so as to move the piston held by the material holding unit into the storage box 8.

[0026] In this embodiment, the frame 1, the feeding component 2, the annealing component 7, the power supply host 4 and the cooling member 5 are all prior art, wherein the annealing component 7 can adopt a heating coil, and during the heating and heat preservation process, the piston is always in the heating coil, and the power supply host 4 can adopt a battery, and the battery supplies power to the heating coil, and the current generates heat through the heating coil, thereby heating the piston located in the heating coil. When heated to a certain temperature, this temperature needs to be maintained for a period of time, and a water supply member is also provided in the frame 1, and the water supply member can adopt a water chiller, and the cooling member 5 includes a cold water pipe and a conveying rack for placing and conveying the piston, and the water chiller supplies The cold water pipe transports cooling water, and cooling water flows continuously in the cold water pipe. The high-temperature piston placed on the conveying rack is cooled by water cooling. The cooled piston is conveyed to the discharge port by the conveying rack. The conveying rack includes a moving component and a placement plate. The moving component can use a square screw lift. The placement plate is installed on the nut seat of the screw lift. The placement plate is controlled to move or park by the screw lift. The high-temperature piston is placed on the placement plate. During the loading process, the piston is pushed into the coil by the loading component 2. After heating, it is pushed to the conveying rack of the cooling part 5. The above components are all existing technologies, and their structures and functions are not repeated here.

[0027] Furthermore, the unloading component 6 also includes a placement table 61, the driving unit includes a driving source 62 and a robotic arm 63 detachably connected to the output end of the driving source 62, the driving source 62 is arranged on the placement table 61, and the driving source 62 is used to control the movement of the robotic arm 63.

[0028] In this embodiment, the discharge port is arranged on the side of the frame 1, and the placement table 61 is also arranged on the side of the frame 1 opposite to the discharge port. It can be detachably installed on the side of the frame 1 by means of a threaded connection, and is located above the discharge port. The driving unit can use an electric mechanical arm, the driving source 62 can use an electric motor, and the mechanical arm 63 can use an electric four-axis mechanical arm, which can carry the material holding unit to move in the up and down and front and back directions, wherein the so-called "up and down" and "front and back" directions are set with reference to the frame 1 (refer to the attached Figure 1 The frame 1 shown, when specifying the orientation of the present invention, the top of the frame 1 is defined as "up", the bottom of the frame 1 is defined as "down", the orientation of the frame 1 toward the front is defined as "front", and the orientation of the frame 1 toward the back is defined as "back"). Optionally, the robot arm 63 can also select a six-axis robot arm. Compared with the four-axis robot arm, the movement of the material holding unit in the left and right directions is increased. It should be noted that the driving unit can also use a pneumatic robot arm and a hydraulic robot arm, and the driving source 62 and the robot arm 63 also select corresponding components accordingly. They are all existing technologies and will not be repeated here.

[0029] Furthermore, a connecting rod 64 is provided on one side of the driving member 65 for connecting the driving member 65 and the mechanical arm 63 , and an air pump 66 is provided on the upper end surface of the driving member 65 .

[0030] Furthermore, the insertion tube 69 is detachably mounted on the movable end of the driving member 65 , and the driving member 65 is used to push and pull the insertion tube 69 to move in the lateral direction of the cooling member 5 .

[0031] In this embodiment, the driving member 65 adopts an electric push rod, which is horizontally arranged to ensure that the insertion tube 69 and the airbag ring enter the piston horizontally, and it is necessary to ensure that the axis of the insertion tube 69 coincides with the extension line of the axis of the piston to ensure that the inner wall of the piston can contact the enlarged airbag 611 at the same time. The so-called active end is the connecting end of the moving rod of the electric push rod, and the insertion tube 69 is detachably connected to the connecting end of the moving rod by a threaded connection. Moreover, it should be noted that the moving rod is arranged horizontally along the frame 1 and faces the discharge port, which enables the insertion tube 69 to be arranged toward the discharge port, so that it is convenient for it to move along the axial direction of the piston to the inside of the piston.

[0032] Furthermore, the airbag ring also includes a fixing ring 68, which is sleeved on the outer wall of the insertion tube 69. The outer side of the fixing ring 68 is recessed radially inward to form a fixing groove. The shape of the airbag 611 is annular, and the inner side of the airbag 611 is embedded in the fixing ring 68.

[0033] In this embodiment, the inner side of the fixing ring 68 is installed on the outer wall of the insertion tube 69 by means of a threaded connection, and the inner side of the annular airbag 611 is also installed in the fixing groove by means of a threaded connection. It is necessary to ensure that the outer wall of the inner side of the airbag 611 is in close contact with the fixing groove. When the air pump 66 inflates the airbag 611, the airbag 611 gradually increases in size until its outer side is in close contact with the inner wall of the piston. The friction between the two enables the piston to be carried by the airbag 611, and is carried out from the discharge port by an electric mechanical arm and an electric push rod, and is placed on a storage box or a conveyor belt. It should be noted that if the piston is placed on a conveyor belt, the electric mechanical arm needs to be used to control the piston to be placed vertically on the conveyor belt, rather than placed sideways on the conveyor belt, so as to prevent the piston from rolling on the conveyor belt.

[0034] Furthermore, the material holding piece also includes an air pipe 67, which is used to connect the output end of the air pump 66 with the input end of the airbag 611. The input end of the airbag 611 is arranged on the inner wall of the airbag 611, and the fixing ring 68 and the insertion tube 69 are both provided with a through hole opposite to the input end of the airbag 611.

[0035] In this embodiment, the input end of the airbag 611 passes through the through hole of the fixing ring 68 on the insertion tube 69 and extends into the insertion tube 69 to facilitate its communication with the air pipe 67 .

[0036] Furthermore, the material holding piece also includes a plurality of branch pipes 610 of the same size, one end of the branch pipe 610 is connected to the output end of the air pipe 67 , and the other end of the branch pipe 610 is connected to the input end of the air bag 611 .

[0037] In this embodiment, there are two airbag rings, and accordingly, there are two airbags 611, so there are two branch pipes 610, and the lengths and apertures of the two branch pipes 610 are equal, which allows the two airbags 611 to deform simultaneously and synchronously. If the amount of gas introduced into the two airbags 611 is different at the same time, then one airbag 611 will be in close contact with the inner wall of the piston while the other airbag 611 is not yet in contact with the inner wall of the piston. At this time, if the friction between a single airbag 611 and the piston is used, The force can also carry the piston, and the general way to determine whether the airbag 611 is inflated to the right position is to observe whether it can carry the piston. Therefore, if the two airbags 611 cannot deform synchronously at the same time, and one airbag 611 is first in contact with the inner wall of the piston, it may mislead the operator to stop inflating when one airbag 611 is inflated but the other airbag 611 is not inflated. Although only one airbag 611 can carry the piston, it is not stable enough compared to two airbags 611 holding the piston at the same time, and it is more likely to fall off.

[0038] Furthermore, the annealing device also includes a controller 3 , and the loading component 2 , the annealing component 7 , the power supply host 4 , the cooling component 5 and the unloading component 6 are all controlled and connected to the controller 3 .

[0039] In this embodiment, the controller 3 controls the mechanical arm 63 to move so that the driving member 65 connected to the mechanical arm 63 faces the discharge port. Then, the controller 3 starts the driving member 65, and moves the insertion tube 69 connected to the moving rod to the inside of the piston at the discharge port (on the cooling member 5, in order to facilitate the movement of the piston, the piston is placed horizontally, so the cavity of the piston can be aligned with the insertion tube 69), and starts the air pump 66 to fill the inside of the two airbags 611 with gas, so that the two airbags 611 are deformed and enlarged until the airbags 611 and the piston are aligned. The inner wall is in close contact, and the friction between the two prevents them from falling off. The driving part 65 is started to retract the insertion tube 69, and then the mechanical arm 63 is started. The piston is placed in the storage box or on the conveyor belt through the movement of the mechanical arm 63 in the up and down and front and back directions (the piston is placed vertically when placed on the conveyor belt), and then the air pump 66 is started to extract the gas inside the two air bags 611 to deflate them. The mechanical arm 63 is started to take the material holding part out of the piston, and the piston is placed in the storage box 8. Then the remaining pistons at the discharge port are processed.

[0040] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
