Description

Technical Field

[0001] The utility model relates to riveting equipment for a pot body and a handle, in particular to a riveting machine for a pot body and a handle. Background Art

[0002] Small-volume kitchenware such as non-stick pans are particularly suitable for processing small amounts of food at home. For easy operation, a rod-shaped handle or an earring-shaped handle needs to be installed on the outer wall of the pan near the edge. There are common ways to connect the handle or ear with the pan, such as welding, screws, and riveting. Riveting is the preferred method for non-stick pans.

[0003] In order to improve the riveting efficiency, a corresponding solution is disclosed in the name of "Continuous automatic riveting equipment for pot body and pot handle docking processing" (CN216705826U, hereinafter referred to as document 1), in which a riveter 15 is fixedly installed at the telescopic end of the second hydraulic cylinder 14, which is responsible for riveting the through hole on the side wall of the pot body 1 and the rivet hole on the front end of the pot handle 2, and the solution does not involve the specific content of how the riveter 15 constrains the rivet.

[0004] The solution disclosed in the title “An adjustable riveting device” (CN 108526376 A, hereinafter referred to as Document 2) can only solve the riveting operations of two rivets at the same time. This solution also involves first machining rivet holes on the cookware body and the handle, and then using the riveting device provided to try to implement riveting.

[0005] Both Documents 1 and 2 mentioned above can realize the automated riveting process, and Document 2 also solves the problem of completing two rivet riveting operations at one time, effectively improving the riveting quality and efficiency. However, if the pot body punching process is established as an independent process, it is necessary to purchase a set of pot body punching equipment. In addition, the pot body needs to be transported and repositioned during riveting. In Document 2, the rivet constraint scheme during riveting is complicated. At the same time, Document 2 has not yet involved the scheme of how to adjust and constrain the posture during the rivet supply process, and has not disclosed the specific scheme of how the rivet is inserted into the riveting hole on the pot body. In Document 1, the posture of the rivet during riveting is that the nail core is horizontal, which further increases the difficulty of constraining the rivet when it is inserted into the riveting hole. Utility Model Content

[0006] The utility model aims to provide a pot body and handle riveting machine, which keeps the rivets inserted into the riveting holes from bottom to top to simplify the rivet restraint scheme and improve the riveting efficiency and riveting quality at the same time.

[0007] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a pot body and handle riveting machine, characterized in that: a pot body support is arranged on one side of the frame box, the inner pot surface of the pot body B is pressed against the pot wall supporting surface of the pot body support, the front end of the rivet push rod has a rivet seat 41 for supporting the rivet head A1 of the rivet A with the rivet rod A2 facing upward, the front end of the rivet push rod is located in the middle airspace of the pot wall supporting surface 11 and corresponds to the bottom of the riveting hole on the pot body B, the rivet push rod supports the rivet A to move upward and pushes the rivet rod A2 to be inserted into the riveting hole, and the riveting core rod located above the rivet A presses down the rod end of the rivet rod A2 to upset the riveted joint.

[0008] In the above technical solution, the formed rivet holes on the pot body B and the handle C are aligned and the positions of the rivet holes are kept unchanged, the rivet push rod supports the rivet A and pushes it to the bottom of the rivet hole on the pot body B, then pushes the rivet A upward and inserts it into the rivet hole, and then the rivet push rod and the rivet core rod cooperate with each other up and down to perform the riveting operation on the pot body and the handle. During the above riveting operation, the front end rivet seat of the rivet push rod is applied to the top surface of the rivet head A1 of the rivet A to support the rivet rod A, the rod body of the rivet rod A2 is completely exposed in a free state, and the rivet head formed by the rivet core rod is located outside the pot body, and the shape of the rivet head A1 on the inner pot surface side of the pot body A is the original formed shape, and the quality of the inner pot wall of the pot after riveting is guaranteed.

[0021] Combination Figures 1 to 8 , a pot body and handle riveting machine, a pot body support platform 10 is arranged on one side of the frame box 1, the inner pot surface of the pot body B is pressed against the pot wall supporting surface 11 of the pot body support platform 10, and the front end of the rivet push rod 40 has a rivet seat 41 for supporting the rivet head A1 of the rivet A with the rivet rod A2 facing upward. The front end of the rivet push rod 40 is located in the middle empty space of the pot wall supporting surface 11 and corresponds to the bottom of the riveting hole on the pot body B. The rivet push rod 40 supports the rivet A to move upward and push the rivet rod A2 to be inserted into the riveting hole, and the riveting core rod 50 located above the rivet A presses down the rod end of the rivet rod A2 to upset the riveted joint.

[0022] The key point of the above scheme is to use the front end rivet seat 41 of the rivet push rod 40 to provide support for the rivet head A1 of the rivet A, so that the rivet rod A2 is in a freely exposed vertical posture, which is convenient for the rivet rod A2 to be efficiently and accurately inserted into the riveting hole, and the shape and top surface quality of the pre-formed rivet head A1 of the rivet A remain basically unchanged during the riveting process, thereby ensuring the inner wall quality of the pot body B.

[0023] The pot support platform 10 is composed of a U-shaped plate with a plate surface located in the plumb direction, the open side plate edge of the U-shaped plate constituting the pot support platform 10 located at the rear is fixedly connected to the front box wall of the frame box 1, and a punching punch 20 is arranged in the U-shaped space surrounded by the U-shaped plate constituting the pot support platform 10. The upper part of the pot support platform 10 is a slope 11a with a low front and a high rear, and the high side of the slope 11a is a flat surface 11b extending backward, and the pot wall support surface 11 is composed of the slope 11a and the flat surface 11b. The above scheme not only provides a support position for the pot body A, but also reserves a layout space for the front end of the rivet push rod 40 with a preset rivet seat 41.

[0024] The pot support platform 10 in the present application is used to place the pot body B to be processed, and the inner pot surface of the pot body B is pressed against the pot wall supporting surface 11 of the pot body support platform 10, so that the handle C is placed on the outer wall surface of the pot wall of the pot body B, avoiding the direct contact between the handle C and the pot wall supporting surface 11 to form a visual blind spot for observing the posture of the handle C, ensuring that the posture of the handle C is easy to observe and fix; the pot wall supporting surface 11 is set to be composed of two parts, the inclined surface 11a and the flat surface 11b, which is set to match the shape of the pot body A. The flat surface 11b refers to a flat state with roughly the same height in the front-to-back direction, and a curved surface between the left and right sides. The curvature of the curved surface is consistent with the curvature of the circumferential direction of the riveting hole position of the pot body B to be riveted and the transition from the bottom of the pot to the pot mouth; the inclined surface 11a refers to a state that changes from low to high from front to back, and the inclination in this direction is also consistent with the transition shape of the pot body B from the bottom of the pot to the pot edge. The left and right directions of the inclined surface 11a are also curved surfaces with appropriate curvature, which are consistent with the curvature of the circumferential direction of the pot body at the corresponding position.

[0025] See also Fig.14 , 15 Taking a non-stick pan as an example, the pan body B and the handle C are riveted together with rivets A. Usually, the handle C is a stamped part. The rivet holes on the handle connecting plate C1 on the handle C that are riveted to the pan body B are formed simultaneously when the handle C is formed. The riveting machine provided in this application needs to complete the forming of the rivet holes on the pan body B first when riveting.

[0026] In order to improve the working efficiency of the equipment, the riveting mechanism of the present application is further optimized so that it has the dual functions of punching holes in the pot body and riveting handles. That is, the above-mentioned scheme provided in the present application can independently realize the riveting operation on the pot body and handle with riveted holes formed therein. The further preferred scheme below can first punch holes in the pot body and handle without riveted holes and then implement the riveting operation.

[0027] A vertically arranged punching punch 20 with a rod core that moves up and down is arranged in the middle empty space constituting the pot wall support surface 11. When the punching punch 20 moves upward to a high position above the pot wall support surface 11, the distance between the punching punch 20 and the pot wall support surface 11 is greater than or equal to the pot wall thickness. A vertically arranged punching sleeve 30 with a tube core that moves up and down is correspondingly arranged above the punching punch 20. When the punching sleeve 30 moves downward, the lower end of the sleeve is pressed on the outer pot surface of the pot body B or the handle connecting plate C1; the front end of the rivet push rod 40 A rivet seat 41 is provided with a rivet head A1 for supporting the rivet A. When the rivet push rod 40 is displaced, it is respectively in the avoidance position for the punching punch 20 and the punching sleeve 30 to cooperate in the punching operation, or when the punching punch 20 moves down to a low position after the riveting hole is punched, the rivet push rod 40 supports the rivet A to move to the bottom of the riveting hole on the pot body B and moves upward to push the rivet A to be inserted into the riveting hole; the punching sleeve 30 has a riveting core rod 50 that moves up and down, and the rivet core rod 50 presses down the rod end of the rivet rod A2 to upset the riveted joint.

[0028] It should be noted that when punching the rivet holes on the pot body B, the pot body B can be placed on the riveting machine for punching, or the handle C can be placed on the set connection installation position on the pot body B to carry out the punching operation. If it is the latter, the punching operation at this time requires the punching punch 20 and the punching sleeve 30 to be aligned with the rivet hole positions already formed on the handle connecting plate C1, so as to avoid damaging the rivet holes already formed on the handle connecting plate C1 when punching the rivet holes on the pot body B, and ensure that the rivet holes punched on the pot body B are aligned with the rivet holes already formed on the handle connecting plate C1 to facilitate the insertion of the rivet A.

[0029] It should be noted that the punching punch 20 and the punching sleeve 30 are located in the area where the flat surface 11b is located. When punching, the punching sleeve 30 can be moved downward to press the pot body B reliably and stably on the flat surface 11b, and then the punching punch 20 is driven up to complete the punching of the riveting hole.

[0030] The punching punch 20 is arranged in the middle empty space of the pot wall supporting surface 11. The punching punch 20 and the punching sleeve 30 that move up and down cooperate with each other to perform punching operations on the pot wall of the pot body B, ensuring the integrity of the contour of the riveting holes on the inner pot surface of the pot body B, and providing a guarantee for the fitting quality of the rivet head A1 and the inner pot surface of the pot body B. Even if there are stamping marks on the rivet joint formed by the upsetting of the rod end of the rivet rod A2 protruding above the outside of the handle connecting plate C1, it does not affect the overall appearance quality of the inner pot surface of the pot body B.

[0031] Since the punching sleeve 30 is equipped with a riveting core rod 50 that can be displaced up and down, it is ensured that the same workstation can complete the punching operation through the cooperation between the punching punch 20 and the punching sleeve 30, and can also realize the cooperation between the rivet seat 41 and the riveting core rod 50 to complete the operation of forming the rod end of the upset rivet rod A2 into an upset riveted joint. In short, the utility model realizes the completion of the two process tasks of punching and riveting in one workstation, which significantly improves the connection efficiency of the pot handle, saves equipment investment costs and maximizes the utilization of the production site; the punching punch 20 and the front end rivet seat 41 of the rivet push rod 40 are arranged in the pot cavity of the pot body B, and the punching sleeve 30 with the riveting core rod 50 that can be displaced up and down is arranged above the outer wall of the pot body B, which ensures that the punching sleeve 30 and the power rod connected thereto are not interfered by the edge of the pot mouth of the pot body B when they are displaced up and down.

[0032] It should also be noted that a robotic arm clamp can be used to clamp the pot body B or simultaneously clamp the pot body B and the handle C to accurately position and place them on the pot wall support surface 11 in the present application. The robotic arm clamp that realizes the above functions belongs to the prior art and is not the technical problem to be solved by the present application, so it will not be elaborated here.

[0033] Preferred as Fig.11 , 12 As shown, the punching punch 20 includes a punch rod 21, and the punch rod 21 is detachably inserted into a blind hole or a stepped hole of a punch seat 22. The punch rod 21 is detachably inserted into the punch seat 22, so that the punch rod 21 that is severely worn can be easily replaced. In order to prevent the punch rod 21 from being retained in the riveted hole and failing to move down synchronously due to the friction between the rivet hole punched and formed on the pot body B and the punch rod 21 when the punch seat 22 moves down after the punching is completed, a structure is provided on the punch seat 22 to realize axial limitation of the rod body of the punch rod 21. For a specific scheme, see Fig.12 , 13 The punch seat 22 is a T-shaped column, which has a stepped hole with a large aperture at the lower end and a small aperture at the upper end. The T-shaped head at the lower end of the punch rod 21 is placed at the T-shaped hole at the lower end of the punch seat 22, thereby forming a limit fit for the punch rod 21 and the punch seat 22 to move downward synchronously. In order to facilitate the replacement of the punch rod 21, the punch seat 22 is inserted into the blind hole with the front end of the swing support rod 60 open and facing upward. A locking screw 23 is provided on the hole wall of the blind hole to lock at the step position on the outer wall of the punch seat 22. Loosen the locking screw 23, the punch rod 21 and the punch seat 22 can be taken out of the blind hole at the front end of the swing support rod 60, tighten the locking screw 23, and the punch rod 21 and the punch seat 22 are reliably fixed in the blind hole at the front end of the swing support rod 60, and the punching operation can be carried out.

[0034] like Figure 3 , 4 As shown in Figure 5, the punching punch 20 is fixed to the upper front end of the swing support rod 60 which is in a free state, the front section of the swing support rod 60 near the front end is hingedly connected to the rod end of the piston rod 71 of the vertically arranged first oil cylinder 70 by a front hinge shaft 61, the rear end of the swing support rod 60 is hingedly connected to the table plate 2 in the frame box 1 by a rear hinge shaft 62, the swinging surface of the swing support rod 60 is located on the plumb plane, and the front hinge shaft 61 and the rear hinge shaft 62 are arranged in parallel with each other in the horizontal direction.

[0035] like Figure 5As shown, the rear end of the swing support rod 60 is hinged to the rear position of the frame box 1 by a rear hinge shaft 62, so that the length of the swing support rod 60 can be appropriately lengthened. During the punching stroke of the punching punch 20 at the front end of the swing support rod 60 to punch the riveting hole, the deflection angle of the column core of the punching punch 20 from the beginning to the end of the punching is extremely small and can be ignored, thereby ensuring that the column core of the punching punch 20 is in a plumb state as a whole to complete the punching of the riveting hole. Therefore, the hole core direction of the punched riveting hole is consistent with the normal direction of the punching hole; The support rod 60 is made of a plate with appropriate thickness, the plate surface of the plate is located in the plumb plane and the swing surface is located on the plumb plane, which ensures that the swing support rod 60 has reliable bending resistance, especially the front hinge shaft 61 of the rod end of the piston rod 71, which is the power fulcrum that drives the swing support rod 60 to swing, is set close to the front end of the swing support rod 60, and the deformation of the front section of the swing support rod 60 before the front hinge shaft 61 due to the bending moment is very small, thereby further ensuring the isotropy of the rod core during the punching stroke of the punching punch 20, and the punching accuracy of the riveting hole is guaranteed.

[0036] like Fig.13 As shown, there is a recess 42 at the lower front end of the rivet push rod 40. When the rivet push rod 40 is located at the position where the push rivet A is inserted into the riveting hole, the punch rod 21 is placed in the recess 42 and the punch seat 21 is supported from bottom to top at the lower front end of the rivet push rod 40. During the riveting process, the punch rod 21 is placed in the recess 42 area, so that the punch seat 22 is supported from bottom to top at the lower front end of the rivet push rod 40. This is extremely important for the rivet push rod 40 that needs to be suspended and has a swinging action. That is, during the riveting process, when the rivet rod A2 is subjected to the downward pressure of the riveting core rod 50, the impact is transmitted from the rivet head A1 to the rivet seat 41, and the concentrated load on the rivet seat 41 is borne by the punch seat 22, and then the swing support rod 60 provides reliable support, thereby providing stable and reliable support for the rivet head A1 during riveting.

[0037] like Figure 3 , 4 As shown in Figures 5, 6, 7 and 8, the middle section of the rivet push rod 40 is hingedly connected to the slide 44 by the first hinge shaft 46, and the slide 44 slides along the guide rail 45 arranged in the front-to-back direction, and the guide rail 45 is fixed on the table 2 in the rack box 1. The rivet push rod 40 and the lower end of the boom rod 81 of the U-shaped hanger 80 with the bayonet facing downward are hinged by the second hinge shaft 83, and the second hinge shaft 83 is located behind the first hinge shaft 46 and the shaft cores of the two are arranged horizontally and parallel. When the U-shaped hanger 80 moves up and down, the rivet push rod 40 is driven to swing in the plumb plane.

[0038] The rear end of the rivet push rod 40 is connected to a second cylinder 150 , which is fixed on the table 2 in the frame box 1 . The second cylinder 150 drives the slide 44 to drive the rivet push rod 40 to move forward and backward along the direction defined by the guide rail 45 .

[0039] The lower end of the lower leg 841 of the gantry 84 is fixedly connected to the slide 44 , and a second oil cylinder 85 is vertically arranged in the middle of the upper crossbeam 842 of the gantry 84 , and the piston rod end of the second oil cylinder 85 is connected to the middle of the upper crossbar 82 of the U-shaped hanger 80 .

[0040] In the above scheme, when the second oil cylinder 85 is extended and retracted, the U-shaped hanger 80 drives the rivet push rod 40 to rotate at a small angle around the first hinge shaft 46, and the small angle swing range is the travel range of the rivet rod A2 of the rivet A from the riveting hole opening to the riveting hole. It should be noted that, in order to avoid the U-shaped hanger 80, the gantry 84 is arranged at a suitable spacing position in front of the U-shaped hanger 80, and the ends of the cantilever 8421 extending backwards are provided at both ends of the upper crossbeam 842 for hingedly fixing the cylinder body of the second oil cylinder 85.

[0041] like Figure 6 , 7 As shown in Figures 8 and 10, the rivet push rod 40 is a groove-shaped cross-section with the notch facing upward. A built-in edge strip 47 is provided at the notch of the front section of the rivet push rod 40. A push rod 48 is arranged in the groove cavity of the rivet push rod 40. A notch 481 for clamping the rivet rod A2 is provided at the front end of the push rod 48. The notch 481 points forward. When the push rod 48 is displaced, it is respectively located at the rear position of the rear end of the edge strip 47 or pushes the rivet A to the position where the rivet seat 41 is located.

[0042] Preferably, the rear end of the push rod 48 is connected to the piston rod end of the first cylinder 90, and the first cylinder 90 is arranged in the front-to-back direction.

[0043] Preferably, the rivet head A1 of the rivet A in the rivet guide tube 100 faces downward and the rivet rod A2 faces upward and falls into the groove cavity on the rivet push rod 40 near the rear end of the edge strip 47.

[0044] A pipe seat 110 is provided at the notch of the rivet push rod 40 near the rear end of the edge strip 47, and the guide pipe 100 is connected to the pipe seat 110 from top to bottom.

[0045] In order to push the rivet A with the rivet head A1 facing downward and the rivet rod A2 facing upward from the position of the tube seat 110 to the rivet seat 41 and keep this posture during the pushing process, the spacing between the notch 481 of the push rod 48 and the bottom of the groove of the rivet push rod 40 is arranged as follows: Fig. 9 As shown, the distance of the spacing is consistent with the thickness of the rivet head A1, that is, the notch 481 is stuck at the joint position of the rivet rod A2 and the rivet head A1, which is equivalent to the lower surface of the notch 481 being close to the plane of the rivet head A1, thus providing a constraint condition for maintaining the posture of the rivet A. Fig. 9As shown, the cross section of the push rod 48 is a groove shape with the notch facing downward, the notch 481 is opened at the front end of the groove bottom plate, and the height of the groove wall is consistent with the thickness of the rivet head A1.

[0046] The tube seat 110 is fixed on the table 2, and the push rod 48 is located between the lower end of the rivet guide tube 100 and the bottom of the groove of the rivet push rod 40 and moves forward and backward. There is a door-shaped notch 101 on the front side tube wall of the lower section of the rivet guide tube 100 for the vertical rivet rod A2 to pass through.

[0047] The above solution is to arrange the lower end of the rivet guide tube 100 and the bottom of the groove of the rivet push rod 40 as close as possible. The distance between the two ensures that the push rod 48 moves forward from the rear of the rivet guide tube 100 to push the rivet A. At this time, the rivet head A1 is located below the rivet guide tube 100 and the upper part of the rivet rod A2 is still located in the rivet guide tube 100, so that the vertical posture of the rivet rod A2 can be maintained.

[0048] In order to ensure that the rivet rod A2 falls vertically onto the bottom of the groove of the rivet push rod 40 and maintains a vertical upward posture when leaving the rivet guide tube 100, a flap door 111 is provided at the door-shaped notch 101, and the upper edge of the flap door 111 is fixedly connected to a horizontal rotating shaft 112, the axial direction of the rotating shaft 112 is perpendicular to the length direction of the push rod 48, the shaft body of the rotating shaft 112 is hinged on the tube seat 110 and an eccentric sleeve 120 is provided on the shaft body outside the tube seat 110, and the gravity acting on the eccentric sleeve 120 drives the flap door 111 to approach the door-shaped notch 101 when the rotating shaft 112 rotates.

[0049] When the rivet push rod 40 pushes the rivet A, it only needs to overcome the reset torque applied by the eccentric sleeve 120 to the flap door 111. Fig. 9 As shown, when rivet A pushes the flap door 111 to flip upward to an appropriate opening height, rivet A is pushed forward continuously, and the flap door 111 flips downward and resets to a position close to the door-shaped notch 101. When the subsequent rivet A arrives, rivet A still maintains a vertical posture with the rivet rod A2 facing upward.

[0050] The structure of the punching sleeve 30 and the riveting mandrel 50 therein will be described below.

[0051] Combination Fig.14 , 15 The punching sleeve 30 is coaxially connected to the lower end of the punching cylinder piston rod 131 of the vertically arranged punching cylinder 130. The punching cylinder piston rod 131 is tubular. The riveting core rod 50 is inserted into the upper end cover of the punching cylinder 130, the punching cylinder piston rod 131 and the punching sleeve 30. The upper end of the riveting core rod 50 located above the upper end cover of the punching cylinder 130 is coaxially connected to the lower end of the piston rod 141 of the riveting cylinder 140.

[0052] The riveting cylinder 140 and the punching cylinder 130 are respectively fixed on the connecting bracket 3 on the frame box 1.

[0053] The above scheme realizes the co-centering arrangement of the punching sleeve 30 for punching the riveting hole of the pot body B and the riveting core rod 50 for upsetting the rod end of the rivet rod A2, so that the riveting operation of the rivet A can be carried out in time after the riveting hole is formed first.

[0054] like Figure 2 As shown, the lower wall of the punching sleeve 30 is connected with an air inlet pipe 31 and a discharge pipe 32 which are opposite to each other. The air inlet pipe 31 and the discharge pipe 32 are connected with the tube cavity of the punching sleeve 30, and the air inlet pipe 31 is connected with a pressure gas source. After the riveting holes are punched, the probability of the disk-shaped waste being accumulated in the tube cavity of the punching sleeve 30 is very high, and it needs to be cleaned up. With the help of the blowing effect of the pressure gas source of the air inlet pipe 31 connected to the pressure gas source, the waste is discharged smoothly and timely from the discharge pipe 32.

[0055] The following is a brief description of the punching rivet holes and riveting process:

[0056] The second cylinder 150 drives the slide 44 to drive the rivet push rod 40 to move backward along the direction defined by the guide rail 45 to the rear position of the waiting state. At this time, the first cylinder 90 pushes the push rod 48 to move forward to push the rivet A to the rivet seat 41 at the front end of the rivet push rod 40. The second oil cylinder 85 retracts to drive the U-shaped hanger 80 to drive the rivet push rod 40 to rotate around the first hinge shaft 46 so that the rivet push rod 40 presents an inclined shape with a high rear end and a low front end. At this time, the rivet A is located at the edge of the pot body B and is in a nearby avoidance position with the punching punch 20.

[0057] The punching punch 20 cooperates with the punching punch sleeve 30 to perform the punching operation. After the punching is completed, the punching punch 20 moves downward, and the second cylinder 150 drives the slide 44 to drive the rivet push rod 40 to move forward along the direction defined by the guide rail 45 to just below the riveting hole. The second oil cylinder 85 extends to drive the U-shaped hanger 80 to drive the rivet push rod 40 to rotate around the first hinge shaft 46 so that the rivet push rod 40 is in a horizontal state. In this process, the rivet A is inserted into the riveting hole.

[0058] The punching punch 20 moves upward until the punch seat 22 is supported on the lower front end of the rivet push rod 40, and the riveting core rod 50 moves downward to complete the upsetting of the upper end of the rivet rod A2 of the rivet A, and the riveting connection process of the handle C and the pot body B is completed.
