Description

Technical Field

[0001] The utility model relates to the field of metal workpiece annealing processing equipment, in particular to a latch workpiece flipping adjustment mechanism and automatic feeding annealing processing equipment. Background Art

[0002] Annealing is a metal heat treatment process, which means slowly heating the metal to a certain temperature, keeping it for a sufficient time, and then cooling it at an appropriate rate. The purpose of annealing is to reduce hardness, improve machinability, improve the mechanical properties of metal products or parts, and improve the material properties or chemical properties of certain special steels. In the actual production process of various metal parts, they need to be annealed to improve their structural properties, facilitate subsequent further processing or deal with problems during use. In the actual use and application process, it is often necessary to anneal cylindrical rod-shaped metal workpieces, such as support rods, latches, or transmission connecting rods, and there are some automated equipment on the market that can complete this processing process.

[0003] For example, a rod-shaped workpiece annealing device disclosed in the Chinese utility model patent document with application number CN201320579245.5 includes a workbench fixed on a frame and an induction heater installed on the workbench; a workpiece guide rail with a V-shaped groove for the workpieces to pass through in sequence is also fixed on the workbench; the induction heater is installed in the middle of the workpiece guide rail; two cylinders are provided above the V-shaped groove and are perpendicular to the V-shaped groove to press the workpiece, and the two cylinders are respectively located on both sides of the induction heater; a sensor is also installed above the V-shaped groove to detect the position of the workpiece in the V-shaped groove and control the opening and closing of the two cylinders. For example, an automatic feeding annealing device for copper tubes disclosed in the Chinese utility model patent document with application number CN201921349704.4 includes: a blanking mechanism, the blanking mechanism includes a blanking frame, a blanking guide rail is installed on the blanking frame at an angle downward, a side plate is installed on the blanking frame and is located on the outside of the blanking guide rail, a front baffle is installed on the front side of the blanking guide rail, a blanking baffle is installed at the bottom of the blanking guide rail, and the guide plate is installed at the bottom of the blanking baffle and extends forward; an annealing mechanism installed on the rear side of the bottom of the blanking mechanism, the annealing mechanism includes an annealing frame, at least two resistance rods vertically arranged downward are installed on the annealing frame, a positioning cylinder is installed on one side of the resistance rod, a positioning fixture is installed on the telescopic shaft of the positioning cylinder, a vertically upward ejecting cylinder is installed correspondingly below the positioning fixture, and a workpiece limit plate is installed on the telescopic shaft of the ejecting cylinder.

[0004] However, the inventors have found that the existing equipment for annealing the latch workpiece cannot accurately control the position of the latch workpiece when it enters the annealing station. Due to different usage requirements and scenarios, different structures are formed locally on the latch workpiece, so it is also necessary to perform differentiated targeted annealing treatments on different local positions on the workpiece. In this process, it is obvious that if the direction and position of the latch workpiece cannot be controlled when it is loaded, it is easy to cause a decrease in processing efficiency or even a failure to meet processing requirements.

[0005] In response to the above-mentioned problems, the utility model provides a method which can automatically judge the ends of the different structural forms of the latch workpiece without human intervention and then adjust the orientation of the latch workpiece during the conveying and moving process, so that all the randomly arranged latch workpieces can enter the annealing processing station with the same orientation, thereby achieving more precise annealing processing and ensuring that the final latch workpiece has better quality.

DETAILED DESCRIPTION

[0043] The following specific embodiments are merely explanations of the present invention and are not limitations of the present invention. After reading this specification, those skilled in the art may make modifications to the embodiments without any creative contribution as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0044] This solution is achieved through the following technical means:

[0045] Embodiment 1: In this embodiment, a method is provided that can automatically judge the ends of the different structural forms of the plug workpieces without human intervention, and then adjust the orientation of the plug workpieces during the conveying and moving process, so that all the randomly arranged plug workpieces 1 enter the annealing processing station in the same orientation, so as to achieve more accurate annealing processing, and make the final obtained plug workpieces 1 have better quality. The equipment mainly includes two main parts: a feeding arrangement and sorting device 2 for sequentially sorting the plug workpieces 1, and a plug annealing heating workbench 4 for heating and heating the plug workpieces 1 after sorting and arranging.

[0046] Specifically, the feeding arrangement and sorting device 2 includes a base platform formed by connecting rods, a vibration plate 21 is placed on the upper part of the base platform at a certain height, a feeding guide rail 22 is connected to the end of the vibration plate 21, and a sorting mechanism 3 for screening the pin workpieces 1 one by one is installed at the end of the feeding guide rail 22. Figure 4 The schematic diagram of the connection position relationship between the various components is given. Here, the loading guide rail 22 is in an inclined state and extends obliquely downward from the end opening of the vibration disk 21, and the sorting mechanism 3 is also connected and installed at the end position of the loading guide rail 22 in an inclined state. At this time, the overall height of the sorting mechanism 3 is lower than the height of the discharge port of the vibration disk 21. Under this structure, when the vibration disk 21 starts working, a large number of latch workpieces 1 placed inside it will move from the inside to the outside one by one to the entrance of the loading guide rail 22 and enter the interior of the guide rail under the action of continuous high-frequency vibration. Since the upper guide rail is in an inclined state, the latch workpiece 1 will slide downward to the sorting mechanism 3 obliquely below under the action of gravity.

[0047] The inventors have noticed that during the entire process of the pin workpiece 1 passing from the vibration plate 21 through the sorting mechanism 3 and entering the annealing and heating device 4, the orientation of the pin workpiece 1 may be uncontrollable. Figure 2 From the shape of the bolt workpiece 1 in the drawing, it can be found that the commonly used bolt workpiece 1 is generally cylindrical in shape, and a circular connection notch is generally provided at its end position for connection and installation with other parts. If the direction of the bolt workpiece 1 during the feeding process cannot be controlled, the accuracy and efficiency of the annealing process will be reduced.

[0048] Therefore, in the scheme given in this embodiment, a latch workpiece flipping adjustment mechanism 9 is installed at the discharge port of the vibration disk 21 to control the loading direction of the latch workpiece 1 without manual intervention. Specifically, the mechanism includes a supporting bottom plate portion 91 extending outward from the end discharge port of the vibration disk 21, and a baffle portion 92 for abutting the rear end of the latch workpiece 1 is also provided at the end of the supporting bottom plate portion 91. On the side of the supporting bottom plate portion 91, a blanking guide cavity 93 is provided, and the side of the blanking guide cavity 93 is connected to the supporting bottom plate portion 91, and at the bottom thereof, a discharge opening 931 for guiding the latch workpiece 1 to fall is opened. In order to achieve the action of changing the adjustment direction of the latch workpiece 1 during the falling process, an abutment adjustment component 94 is also provided at the discharge opening 931. For details, refer to the attached manual. Figure 1 and 2 In the structural diagram given, the abutment adjustment assembly 94 includes a supporting protrusion 941 arranged at the front and rear ends of the blanking guide cavity 93. The supporting protrusion 91 here can be formed on a sheet-like plate installed at the front and rear sections respectively, and the supporting protrusion 941 extends horizontally from one side of the supporting bottom plate 91 to one side of the blanking guide cavity 93. It should be noted that the spacing formed between the front end of the supporting protrusion 941 and the inner wall surface of the blanking guide cavity 93 opposite to it is between the width of the narrower end and the width of the wider end of the bolt workpiece 1.

[0049] Under this structure, when the vibration plate 21 starts working, a large number of latch workpieces 1 stacked inside the vibration plate 21 will move from the inside to the outside along the track of the vibration plate 21 to the supporting bottom plate portion 91. At the same time, under the abutment of the vertically arranged baffle portion 92, the latch workpiece 1 will not continue to move outward. It should also be noted that the supporting bottom plate 91 here should have a certain inclination angle downward toward the side of the discharge opening 931, so that the latch workpiece 1 will roll toward the side of the blanking guide cavity 93 under the action of its own gravity. At this time, due to the existence of the two sections of the supporting protrusions 941, the radial dimension of the end of the latch workpiece 1 without the circular notch is larger, so it will be abutted and supported by the supporting protrusion 941 at the connection and the inner wall surface of the blanking guide cavity 93, so that the end of the latch workpiece 1 on this side cannot fall; correspondingly, the local radial dimension of the end of the latch workpiece 1 with the circular notch will be smaller than the distance between the supporting protrusion 941 and the inner wall surface of the blanking guide cavity 93, so that the end of the latch workpiece 1 on this side can fall down smoothly. Under this structure, no matter which end of the latch workpiece 1 is facing forward when it is discharged from the vibration plate 23, the end with the arc-shaped notch can fall into the lower guide rail first relative to the other end, so that the discharged latch workpiece 1 will always be loaded in a state where the end with the circular notch is in front, thereby completing the automatic control of the loading direction of the latch workpiece 1. Of course, although the present embodiment shows a structural state of a latch workpiece 1 with a circular groove, the latch workpiece flipping adjustment mechanism 9 is also applicable to various types of latch workpieces 1 with different radial dimensions at both ends, such as those with stepped surfaces at other ends and those with a conical shape as a whole.

[0050] As a preferred embodiment of the above-mentioned latch workpiece flip adjustment mechanism 9, a circular arc guide plate 95 for guiding the latch workpiece 1 to fall and move can be further provided below the discharge opening 931 to reduce the collision between the latch workpiece 1 and other components during the falling process, so that the workpiece can be discharged more smoothly. Furthermore, the length of the blanking guide cavity 93 and the distance between the two supporting protrusions 941 can be designed as a movable and adjustable structure. For example, referring to the attached manual Figure 2 The structure given can be formed with a long strip of slots on the sheet plate formed with the supporting protrusion 941 and at the connection of one end of the blanking guide cavity 93, and connected and fixed by bolts. At this time, the length of the blanking guide cavity 93 and the spacing between the two supporting protrusions 941 can be changed and adjusted by adjusting the bolts in the relaxed state, and then the bolts are used to fix each component at the station, thereby realizing the adaptive adjustment of the pin workpieces 1 of various sizes and specifications, greatly improving the versatility of the flip adjustment mechanism.

[0051] For the structure of the sorting mechanism 3, please refer to the attached manual. Figure 7 and 8 Here, the order of the front and rear positions is defined by the order of the loading direction of the latch workpiece 1. The sorting mechanism 3 is installed as a whole at the rear end position of the aforementioned loading guide rail 22, and it also includes a sorting support block 31 directly abutting against the end opening of the loading guide rail 22 and a blocking member 32 installed behind the sorting support block 31. The blocking member 32 can perform reciprocating translational motion relative to the sorting support block 31 driven by a driving device 34. Specifically, the sorting support block 31 is in the shape of a rectangular block as a whole, and a first support surface 311 is formed on the top thereof for directly fitting with the end face of the aforementioned feeding guide rail 22, and a cylindrical accommodating cavity 312 is provided on the sorting support block 31, which is through from top to bottom; and the blocking member 32 is in the shape of a flat plate as a whole, and a smooth second support surface 321 is formed on the upper part thereof, which is used to fit with the bottom surface of the sorting support block 31 and simultaneously close the rear end opening of the aforementioned accommodating cavity 312, and a sorting through groove 322 is provided on the blocking member 32, which is through from top to bottom and is cylindrical, for the pin workpiece 1 to pass through. As a preferred structure, a stepper motor can be used as the driving device 34, and by fixedly connecting the output section of the stepper motor to the sorting support block 31, the reciprocating translational movement of the sorting support block 31 relative to the blocking member 32 can be accurately controlled in the power-on state. Of course, it should be noted here that the length of the aforementioned accommodating cavity 312 opened on the sorting support block 31 is equal to the length of a latch workpiece 1 and the axis of the accommodating cavity 312 is parallel to the extension direction of the upper loading guide rail 22, thereby ensuring that when the accommodating cavity 312 is opposite to the end opening of the loading guide rail 22, the latch workpiece 1 can slide smoothly along the track into the interior of the chamber, and the chamber can accommodate just one latch workpiece 1.

[0052] When the sorting mechanism 3 is working, first, the sorting support block 31 is driven by the driving device 34 to move to the side of the sorting mechanism 3. Figure 7 In the first working position state, the latch workpiece 1 will slide down from top to bottom into the accommodating chamber 312. In this state, other latch workpieces 1 located above the latch workpiece 1 are supported by the top surface of the latch workpiece 1 in the chamber, and thus cannot continue to slide down into the accommodating chamber 312. At the same time, since the bottom of the accommodating chamber 312 is closed by the second supporting surface 321, the latch workpiece 1 cannot continue to move backward. Subsequently, the driving device 34 drives the sorting supporting block 31 to move to the other side. At this time, the sorting mechanism 3 as a whole is as shown in the attached manual. Figure 8In the second working position state, at this time, the bottom surface of the accommodating cavity 312 is connected to the sorting slot 322 provided on the blocking member 32, so the latch workpiece 1 will slide and move through the blocking member 32 under the action of gravity, and the first support surface 311 can now play a role of stopping and limiting the latch workpiece 1 still in the feeding guide rail 22, preventing it from sliding down. When the latch workpiece 1 in the accommodating cavity 312 is discharged and moved to the next station for annealing and heating treatment, the driving device 34 can drive the sorting support top block 31 to move back to the first working position, and this is repeated to achieve the sorting and feeding processing action of a large number of latch workpieces 1.

[0053] As a preferred embodiment, in order to more accurately control the falling movement of the latch workpiece 1, a centrally controlled guiding discharge pipe 33 may be further connected to the rear end of the sorting slot 322.

[0054] The aforementioned latch annealing and heating workbench 4 is integrally arranged on the side of the loading, arranging and sorting device 2, and includes several main parts 51, including a heating device 5, a workpiece supporting mechanism 6 and an adjustment guide 7. The latch annealing and heating workbench 4 here also includes a base platform for installing and setting these main parts 51, wherein the heating device 5 includes a main part 51 fixedly installed on the base platform, and a copper metal heating tube 52 extends outwardly from the main part 51 in a horizontal direction, and an annular section 521 is formed on the outermost end of the heating tube 52. Above the annular section 521, a horizontal mounting plate is arranged, and an adjustment guide 7 is fixedly installed on the mounting plate. Refer to the attached manual. Fig. 9In the structure given, the adjustment guide 7 is in the shape of a vertical truncated cone that is larger at the top and smaller at the bottom. A guide channel that runs through the top and bottom is provided inside the guide channel. The guide channel includes an expanded receiving section 71 at the top and an adjustment guide section 72 at the bottom, which are respectively used to receive the latch workpiece 1 discharged from the end of the sorting mechanism 3 and to adjust the latch workpiece 1 to a vertical state after passing through the channel. The aforementioned workpiece support mechanism 6 is arranged as a whole below the heating tube 52, and includes a flat heating support plate 61. A vertical moving component 64 for driving the heating support plate 61 to move up and down in the vertical direction and a horizontal moving component 62 for driving the heating support plate 61 to move back and forth in the horizontal direction are installed between the heating support plate and the base platform. The moving component here can be a combination of a guide rail and a lifting support cylinder. Of course, other corresponding alternative structural components can also be selected, which will not be described in detail here. A discharge limiting abutment member 63 is also installed between the adjustment guide member 7 and the heating support plate 61, and a guide limiting hole 631 is provided on the discharge limiting abutment member 63 for the insertion of the pin workpiece 1. It should also be noted that the heating tube 52 is formed with an annular segment 521 having a common central axis with the guide channel.

[0055] When the latch workpiece 1 is thrown outward from the aforementioned loading arrangement and sorting device 2 under the action of gravity, it will fall into the flared receiving section 71 in the adjustment guide 7 on the latch annealing and heating workbench 4. Then, under the combined action of the arc-shaped inner wall surface of the flared receiving section 71 and the gravity of the workpiece itself, the latch workpiece 1 will continue to move downward and pass through the adjustment guide section 72. At this time, the latch workpiece 1 will fall in an upright state through the action of the adjustment guide 7. It should be noted here that before the latch workpiece 1 falls, it is necessary to first use the vertical moving component 64 to move the heating support plate 61 to a higher position to receive the workpiece, so as to reduce the collision between the workpiece and the equipment components during the loading process. As the latch workpiece 1 falls vertically, its lower end will pass through the aforementioned guide limit hole 631 and contact the heating support plate 61. At this time, the latch workpiece 1 will be in an upright state and located at the center of the annular portion. Subsequently, it is only necessary to start the vertical moving assembly 64 and lower the heating support plate 61 supporting the latch workpiece 1 to a certain height, and then the heating device 5 can be started to work. Under the action of the high-frequency alternating magnetic field generated in the inner area of ​​the annular portion, a part of the latch workpiece 1 is heated first, until the entire latch workpiece 1 is heated to the target temperature state.

[0056] After the heating process of the latch workpiece 1 is completed, the lateral movement component 62 can be started to drive the heating support plate 61 supporting the latch workpiece 1 to move to one side. At this time, since the inner wall of the guide limit hole 631 provided on the discharge limit abutment 63 abuts against the outer wall surface of the latch workpiece 1, the lateral movement of the workpiece will be limited by the discharge limit abutment 63. As the heating support plate 61 continues to move and is laterally pulled away from the bottom of the latch workpiece 1, the bottom of the latch workpiece 1 loses its supporting function and the material will fall downward. Subsequently, each component mechanism is reset to its original state, and the next latch workpiece 1 that continues to enter can be heated and annealed again.

[0057] As a further preferred structure, a flexible heat-insulating material cushion layer 611, such as a disc-shaped support sheet made of high-temperature engineering plastic or rubber, can be installed at the position of the aforementioned heating support plate 61, and the component is arranged at the position where the upper surface of the aforementioned heating support plate 61 is directly opposite to the annular segment 521. The arrangement of the material layer can effectively reduce the collision between the parts during the falling process of the latch workpiece 1, and can also reduce the heat loss to the heating support plate during the heating process, thereby achieving more precise adjustment and control of the annealing heating position and process of the workpiece.

[0058] Of course, in order to collect the latch workpieces 1 that have completed the heating treatment so that they can gradually cool down and end the entire annealing process, a hollow blanking receiving box 8 that is open upward is also provided at the bottom of the equipment.

[0059] Embodiment 2: In this embodiment, an improved technical solution is further provided. Here, all the component structures provided in the embodiment are different in that the workpiece supporting mechanism 6 in embodiment 1 is adjusted under different usage scenarios.

[0060] Here, the inventor needs to explain that in Example 1, a transverse reciprocating translation mechanism is used to realize the support or blanking action of the plug workpiece 1. The selection of such a workpiece supporting mechanism 6 is mainly due to the fact that some plug workpieces 1 with larger size and mass will produce a larger impact when falling from top to bottom onto the aforementioned heating support plate 61, and in the process of heating the plug workpiece 1, it is also necessary to provide it with a larger supporting force. Obviously, the translational guide rail structure used in Example 1 separates the track component that plays a supporting role from the pushing device used for pushing, so as to provide a larger supporting force for the workpiece. The corresponding problem is that under this structure, when the heating support plate 61 is reversely translated and reset, it is easy for the plug workpiece 1 to collide with the heating tube 52. Therefore, in this scheme, a discharging limit abutment 63 is used to achieve the separation and discharging of the plug workpiece 1 from the heating support plate 61. However, under this structure, the latch workpiece 1 is still prone to being squeezed and collided with the heating tube 52 during the translation process following the heating support plate 61, thereby damaging the guide limit hole 631 opened on the discharge limit abutment.

[0061] Therefore, in this embodiment, considering the annealing processing scenarios of some small-sized and small-weight plug workpieces 1, the lateral moving assembly 62 in the original workpiece support mechanism 6 is replaced by a combination structure of a support support plate 65 and a rotary drive device 66. Specifically, the rotary drive device 66 here can select a stepper motor, and the output end of the stepper motor and the gear mechanism cooperate to drive the support support plate 65 to rotate around the end of one side of itself, so as to switch between the horizontal and vertical states. On the other end of the support support plate 65, a cylindrical upwardly protruding support block 651 is installed to directly abut against the bottom surface of the plug workpiece 1. At this time, in the initial state, the supporting top plate 65 in the workpiece supporting mechanism 6 is in a horizontal state, and once the latch workpiece 1 completes the heating process, it only needs to start the stepper motor serving as the rotary drive device 66 to drive the supporting top plate 65 to rotate downward to a vertical state, so that the latch workpiece 1 can complete the falling and discharging action after the heating is completed without contacting or colliding with other components.

[0062] Of course, under this structure, a flexible heat-insulating material pad 611 can still be installed on the top of the support block 651, and the aforementioned discharge limit abutment 63 can still be provided, but under this structure, the discharge limit abutment 63 no longer needs to participate in the blanking process of the latch workpiece 1, but only needs to guide the process of the workpiece moving from top to bottom onto the heating support plate 61, thereby making the position of the latch workpiece 1 on the work station more precisely controllable.

[0063] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
