Description

Technical Field

[0001] The invention relates to the technical field of metal chain hole punching, and more specifically to a chain processing hole punching machine. Background Art

[0002] Chains are generally metal links or rings, mostly used for mechanical transmission and traction; chain-shaped objects used to block traffic passages (such as in streets, rivers or harbor entrances), chains for mechanical transmission.

[0003] At present, in the processing of metal chains, it is necessary to perform hole drilling on the metal chain blanks, that is, to punch holes on thin metal plates. Usually, the metal chain blanks need to be loaded, punched, polished, and unloaded. The traditional chain processing hole drilling method usually uses manual or low-automation equipment, which is cumbersome, labor-intensive, and inefficient. It is also easy to have uneven hole sizes and position deviations, resulting in the need for repeated rework, which seriously affects the hole drilling efficiency.

[0004] In view of the above problems, some solutions have been provided in the prior art. For example, the Chinese invention application with publication number CN118371592A discloses a metal chain processing hole punching machine. The device sets a punching mechanism and moves the movable plate downward, which can drive the punching block to move downward. The metal chain blank is first pressed by the second pressure frame to ensure the stability of the hole punching process of the metal chain blank, which can ensure the hole punching quality and improve the hole punching efficiency. However, during use, the chain blank is often placed on the top wall of the workbench manually. Due to certain errors in manual placement, uneven hole sizes and position deviations are likely to occur, resulting in repeated rework. Although the prior art has improved it and limited the chain blank by a limit groove, when punching holes in chain blanks of different sizes, the user needs to spend time replacing different hole punching machines, which will still seriously affect the hole punching efficiency.

[0010] Furthermore, a cavity is opened on the arc plate, a negative pressure hole is opened on the cavity, a second air pipe is opened on the cavity, a first connecting hole connected to the second air pipe is opened on the limiting rod, and a second connecting hole connected to the first connecting hole is opened on the connecting plate.

[0011] Furthermore, a groove connected to the second air pipe is formed on the side wall of the connecting plate, an air inlet hole connected to the second air pipe is formed on the first connecting hole, and an exhaust valve whose output end is connected to the outside is inserted on the mounting tube.

[0012] Furthermore, the stamping assembly includes a stamping machine installed on a mounting block, the mounting block is provided with a vertical groove, a stamping block fixedly connected to the output end of the stamping machine is slidably installed in the vertical groove, an adjustment groove is provided on the stamping block, a slider is symmetrically slidably installed in the adjustment groove, a bidirectional threaded rod is rotatably installed on the stamping block, and the bidirectional threaded rod is threadably matched with the slider, and a stamping head is installed on the bottom wall of the slider.

[0013] Furthermore, a first magnet is embedded on the linkage rod, a second magnet that repel each other with the first magnet is embedded on the top wall of the workbench, and a collecting cavity is opened on the workbench, a collecting box is slidably installed in the collecting cavity, and a collecting groove is opened on the top wall of the collecting cavity.

[0014] Furthermore, a punching groove is provided on the top wall of the workbench, a waste groove connected to the punching groove is provided on the side wall of the workbench, and a waste box is movably installed in the waste groove.

[0016] Furthermore, a sliding rod is rotatably mounted on the linkage rod.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) In this scheme, the push plate and the connecting rod cooperate. When the mounting block drives the punching assembly to move downward to punch a hole, the push plate can drive the fixing assembly to align the chain blank and make the chain blank directly under the punching assembly to avoid errors in the punching holes that affect production efficiency. At the same time, the mounting cylinder, the first spring, the horizontal rod, and the arc plate cooperate to clamp chain blanks of different sizes, thereby eliminating the need for users to spend time replacing the punching machine, thereby improving production efficiency. (2) This solution can limit the position of the mounting tube and the connecting plate by the cooperation of the fixing rod and the limiting rod, so that the arc plate can be limited by the horizontal rod on the connecting plate, so as to avoid the chain blank from moving the connecting plate through the arc plate and the horizontal rod during the punching process, which affects the punching effect and causes the need for rework, thereby further improving production efficiency; (3) This scheme opens a cavity, and drives the groove to move during the movement of the limit rod. When the limit rod is inserted into the limit groove, the groove is connected to the second air pipe. At this time, the space where the mounting tube is located on the side of the connecting plate close to the first spring draws air from the cavity through the air inlet hole, the groove, and the second air pipe, and reduces the pressure in the cavity. Then, under the action of pressure, the cavity tends to draw air from the outside through the negative pressure hole. At this time, the arc plate fits tightly with the side wall of the chain blank, so that the negative pressure hole fits with the chain blank. Then, under the action of pressure, the arc plate and the chain blank are tightly sucked together, thereby improving the hole opening accuracy of the chain blank, that is, reducing the probability of rework of the chain blank, and further improving production efficiency.

There is a horizontal rod 807, and an arc plate 808 is fixedly installed at one end of the horizontal rod 807 away from the connecting plate 805. The top plate 3 is installed with a hydraulic rod 809, and a mounting block 810 is fixedly installed on the output end of the hydraulic rod 809.

[0022] The limiting component 9 includes a fixing groove 901 provided on the side wall of the slide groove 801, a horizontal groove provided on the slide plate 802, a fixing rod 902 slidably installed in the horizontal groove, an elastic pad 903 is fixedly installed between the fixing rod 902 and the horizontal groove, a linkage groove 904 is provided on the fixing rod 902, a linkage rod 905 extending into the linkage groove 904 is vertically slidably installed on the slide plate 802, and a linkage component 10 cooperating with the elastic pad 903 is provided on the connecting plate 805.

[0023] The linkage assembly 10 includes a mounting groove 105 provided on the connecting plate 805, a limiting rod 101 is slidingly and sealingly installed in the mounting groove 105, a limiting groove 102 is provided on the inner wall of the mounting tube 804, a cavity 103 is provided on the elastic pad 903, and a first air pipe 104 connected to the mounting groove 105 is inserted into the cavity 103.

[0024] During use, the user can place the chain blank between the arc plates 808 of the two limit rods 101, and then the output end of the hydraulic rod 809 extends and drives the mounting block 810 to move downward, and in the process of the mounting block 810 moving downward, drives the push plate 811 to move downward, and then in the process of the push plate 811 moving downward, the inclined groove 812 gradually contacts with the slide plate 802 and applies a thrust to the slide plate 802, and then under the action of the thrust, the slide plate 802 moves along the slide groove 801, at this time, the linkage spring 803 is stretched and has a tendency to recover, and in the process of the movement of the slide plate 802, drives the mounting cylinder 804 to move, and then in the process of the movement of the mounting cylinder 804, drives the arc plate 808 to gradually contact with the chain blank through the connecting plate 805 and the horizontal rod 807 and applies a thrust to the chain blank Then, under the thrust of the two curved plates 808, the chain blank can be moved to the bottom of the stamping assembly 12. At the same time, under the action of the curved surface of the curved plate 808, the chain blank can be straightened to ensure that the chain blank is moved to the bottom of the stamping assembly 12 to avoid errors in the stamping holes affecting production efficiency. After the installation cylinder 804 drives the curved plate 808 to clamp the chain blank through the connecting plate 805 and the horizontal rod 807, as the slide plate 802 drives the installation cylinder 804 to continue to move, the curved plate 808 drives the connecting plate 805 through the horizontal rod 807 to slide in the installation cylinder 804 and stretch the first spring 806, so that chain blanks of different sizes can be clamped, so that the user does not need to spend time replacing the hole opening machine, thereby improving production efficiency.

[0025] In the process of the inclined groove 812 of the push plate 811 driving the mounting block 810 to move, the bottom wall of the push plate 811 gradually contacts with the connecting rod 905 and applies a downward thrust to the connecting rod 905, and then the connecting rod 905 moves downward under the action of the thrust, and in the process of the connecting rod 905 moving downward, it gradually contacts with the connecting groove 904 of the fixed rod 902 and applies a thrust to the connecting groove 904, and then the fixed rod 902 moves along the horizontal groove under the action of the thrust, and after the inclined groove 812 of the push plate 811 is out of contact with the mounting block 810, the fixing rod 902 is inserted into the fixing groove 901, so that the position of the mounting block 810 can be limited to prepare for subsequent automatic unloading.

[0026] In the process of the connecting rod 905 driving the fixing rod 902 to insert into the fixing groove 901, the elastic pad 903 is squeezed and has a tendency to recover, and in the process of the elastic pad 903 being squeezed, the airflow in the cavity 103 flows to the installation groove 105 through the first air pipe 104, and the pressure in the installation groove 105 increases, and then the limit rod 101 slides along the installation groove 105 under the action of pressure, and when the fixing rod 902 is inserted into the fixing groove 901, the limit rod 101 is inserted into the limit groove 102, thereby avoiding the chain blank from driving the connecting plate 805 to move through the arc plate 808 and the horizontal rod 807 during the punching process, affecting the punching effect, and causing the need for rework, thereby further improving production efficiency.

[0027] like Figure 3 , Figure 4 As shown, the arc plate 808 is provided with a cavity 111, the cavity 111 is provided with a negative pressure hole 112, the cavity 111 is provided with a second air pipe 113, the limiting rod 101 is provided with a first connecting hole 114 connected to the second air pipe 113, and the connecting plate 805 is provided with a second connecting hole 115 connected to the first connecting hole 114.

[0028] The side wall of the connecting plate 805 is provided with a groove 116 connected to the second air pipe 113, and the first connecting hole 114 is provided with an air inlet 117 connected to the second air pipe 113. The mounting tube 804 is provided with an exhaust valve 118 whose output end is connected to the outside.

[0029] By adopting the above technical solution, in the process of the connecting plate 805 moving along the installation cylinder 804 and stretching the first spring 806, the pressure in the space on the side of the connecting plate 805 close to the first spring 806 in the installation cylinder 804 is reduced. At this time, the space on the side of the connecting plate 805 close to the first spring 806 in the installation cylinder 804 has a tendency to inhale air from the outside, and then drives the groove 116 to move during the movement of the limit rod 101. When the limit rod 101 is inserted into the limit groove 102, the groove 116 is connected to the second air pipe 113. At this time, the installation cylinder 804 is located at the connecting plate 805 close to the first spring The space on one side of the spring 806 draws air from the cavity 111 through the air inlet hole 117, the groove 116, and the second air pipe 113, and reduces the pressure in the cavity 111. Then, under the action of pressure, the cavity 111 tends to draw air from the outside through the negative pressure hole 112. At this time, the arc plate 808 is tightly fitted with the side wall of the chain blank, so that the negative pressure hole 112 is fitted with the chain blank. Then, under the action of pressure, the arc plate 808 and the chain blank are tightly sucked together, thereby improving the opening accuracy of the chain blank, that is, reducing the probability of rework of the reworked chain blank, and further improving production efficiency.

[0030] During the process of the connecting plate 805 stretching the first spring 806, the air flow in the space on the side of the connecting plate 805 away from the first spring 806 in the installation cylinder 804 is squeezed, and flows into the cavity 111 through the second connecting hole 115, the first connecting hole 114, and the second air pipe 113, and then blows toward the side wall of the chain blank through the negative pressure hole 112 on the cavity 111, thereby cleaning the dust particles adhering to the side wall of the chain blank, ensuring that the arc plate 808 can fit tightly against the chain blank.

[0031] like Figure 5 , Figure 6 As shown, the stamping assembly 12 includes a stamping machine 122 installed on a mounting block 810, the mounting block 810 is provided with a vertical groove, a stamping block 123 fixedly connected to the output end of the stamping machine 122 is slidably installed in the vertical groove, an adjusting groove is provided on the stamping block 123, a slider 124 is symmetrically slidably installed in the adjusting groove, a bidirectional threaded rod 125 is rotatably installed on the stamping block 123, and the bidirectional threaded rod 125 is threadedly matched with the slider 124, and a stamping head 126 is installed on the bottom wall of the slider 124.

[0032] By adopting the above technical solution, after the bottom wall of the push plate 811 contacts the mounting block 810, the user can start the punching machine 122, and then the output end of the punching machine 122 punches the chain blank through the punching block 123, the slider 124, and the punching head 126. Since the distance between the two holes on different chains may be different, when the holes on the chain blank need to be adjusted, the user can rotate the bidirectional threaded rod 125. During the rotation of the bidirectional threaded rod 125, the two sliders 124 can be driven to move, and then during the movement of the two sliders 124, the two punching heads 126 can be driven to move, so that holes can be opened in different chain blanks, further improving production efficiency.

[0033] like Figure 2 , Figure 7 As shown, a first magnet 131 is embedded on the linkage rod 905, a second magnet 132 which repel each other with the first magnet 131 is embedded on the top wall of the workbench 1, and a collecting chamber is opened on the workbench 1, a collecting box 134 is slidably installed in the collecting chamber, and a collecting groove 133 is opened on the top wall of the collecting chamber.

[0034] By adopting the above technical solution, when the hole drilling is completed, the user can reset the control punching machine 122, and then shrink the output end of the hydraulic rod 809. During the shrinkage of the output end of the hydraulic rod 809, the mounting block 810 is driven to move upward. During the upward movement of the mounting block 810, the push plate 811 is driven to move upward and disengage from the mounting block 810. At this time, under the action of the fixing rod 902 and the fixing groove 901, the linkage spring 803 cannot drive the mounting plate to reset. Then the output end of the stepping motor 4 drives the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the push plate 811 is driven to move upward and disengage from the mounting block 810. The fixing assembly 8 on the mounting rod 6 drives the chain blank after the hole is opened to rotate, and during the rotation of the fixing assembly 8, the first magnet 131 is driven to gradually approach the second magnet 132, and when the chain blank is located directly above the collecting groove 133, the distance between the first magnet 131 and the second magnet 132 is the shortest, and then under the action of the repulsive force between the first magnet 131 and the second magnet 132, the second magnet 132 drives the linkage rod 905 to move upward and break away from the side wall of the fixing rod 902, at which time the elastic pad 903 stretches and drives the fixing rod 902 to reset, and At the same time, during the extension of the elastic pad 903, air is sucked from the installation groove 105 through the first air pipe 104, and the pressure in the installation groove 105 is reduced. Then, under the action of the pressure, the limiting rod 101 moves along the installation groove 105 and disengages from the limiting groove 102. At this time, the first spring 806 contracts and drives the connecting plate 805 to reset. During the reset of the limiting rod 101, the groove 116 is disengaged from the second air pipe 113, and the first connecting hole 114 is connected to the second air pipe 113 again. At the same time, the linkage spring 803 contracts and drives the installation block 8 10 is reset, at this time, the space in the installation cylinder 804 located on the side of the connecting plate 805 close to the first spring 806 can discharge the excess airflow through the exhaust valve 118, and then during the resetting process of the installation block 810, the arc plate 808 is driven to reset and break contact with the chain blank through the installation cylinder 804, the connecting plate 805, and the horizontal rod 807, and then the chain blank falls downward under the action of gravity and enters the collection box 134 through the collection groove 133, thereby eliminating the need for users to spend time sorting the chain blanks after the holes are opened, further improving production efficiency.

[0035] like Figure 1 , Figure 2 As shown, a punching groove 127 is provided on the top wall of the workbench 1 , a waste groove 14 connected to the punching groove 127 is provided on the side wall of the workbench 1 , and a waste box 15 is movably installed in the waste groove 14 .

[0036] By adopting the above technical solution and setting up a waste box 15, after the punching head 126 makes a hole in the chain blank, the waste generated during the hole making process enters the waste box 15 through the waste slot 14, thereby eliminating the need for personnel to spend a long time cleaning the waste, thereby further improving production efficiency.

[0037] like Figure 3 As shown, one end of the fixing rod 902 close to the fixing slot 901 is in an inclined surface.

[0038] By adopting the above technical solution, during the process of inserting the fixing rod 902 into the fixing groove 901 , the fixing rod 902 can be easily inserted into the fixing groove 901 by making one end of the fixing rod 902 close to the fixing groove 901 be inclined.

[0039] like Figure 8 As shown, a slide bar 16 is rotatably mounted on the linkage rod 905 .

[0040] By adopting the above technical solution, in the process of the connecting rod 905 pushing one end of the fixed rod 902 through the inclined groove 812, the sliding friction between the connecting rod 905 and the inclined groove 812 can be converted into rolling friction between the slide rod 16 and the inclined groove 812 by making the slide rod 16, thereby reducing the resistance when the connecting rod 905 pushes the fixed rod 902, and can also reduce the resistance when the first magnet 131 drives the connecting rod 905 to move upward through the second magnet 132, thereby improving the stability of the operation of the device.

[0041] Instructions for use: When in use, the user can place the chain blank between the two limit rods 101 arc plates 808, and then the output end of the hydraulic rod 809 extends and drives the mounting block 810 to move downward, and in the process of the mounting block 810 moving downward, the push plate 811 is driven to move downward, and then in the process of the push plate 811 moving downward, the inclined groove 812 gradually contacts the slide plate 802 and applies a thrust to the slide plate 802, and then under the action of the thrust, the slide plate 802 moves along the slide groove 801, and at this time the linkage spring 803 is stretched and has There is a tendency to recover, and the installation cylinder 804 is driven to move during the movement of the slide plate 802, and then the arc plate 808 is driven to gradually contact the chain blank and apply thrust to the chain blank through the connecting plate 805 and the horizontal rod 807 during the movement of the installation cylinder 804, and then the chain blank can be moved to the bottom of the stamping assembly 12 under the thrust of the two arc plates 808, and the chain blank can be straightened under the action of the arc surface of the arc plate 808, so as to ensure that the chain blank moves to the right below the stamping assembly 12 to avoid the impact. The error of pressing holes affects the production efficiency. After the installation cylinder 804 drives the arc plate 808 to clamp the chain blank through the connecting plate 805 and the horizontal rod 807, as the slide plate 802 drives the installation cylinder 804 to continue to move, the arc plate 808 drives the connecting plate 805 to slide in the installation cylinder 804 through the horizontal rod 807 and stretch the first spring 806, so that chain blanks of different sizes can be clamped; in the process of the connecting rod 905 driving the fixing rod 902 to insert into the fixing groove 901, the elastic pad 903 The elastic pad 903 is squeezed and has a tendency to recover. During the squeezing of the elastic pad 903, the airflow in the cavity 103 flows into the mounting groove 105 through the first air pipe 104, and the pressure in the mounting groove 105 increases. Then, under the action of the pressure, the limiting rod 101 slides along the mounting groove 105, and when the fixing rod 902 is inserted into the fixing groove 901, the limiting rod 101 is inserted into the limiting groove 102, thereby preventing the chain blank from driving the connecting plate 805 to move through the arc plate 808 and the horizontal rod 807 to affect the punching effect during the punching process;During the process of the connecting plate 805 moving along the installation tube 804 and stretching the first spring 806, the pressure in the space on the side of the connecting plate 805 close to the first spring 806 in the installation tube 804 decreases. At this time, the space on the side of the connecting plate 805 close to the first spring 806 in the installation tube 804 tends to inhale air from the outside, and then drives the groove 116 to move during the movement of the limit rod 101. When the limit rod 101 is inserted into the limit groove 102, the groove 116 is connected to the second air pipe 113. At this time, the space on the side of the connecting plate 805 close to the first spring 806 in the installation tube 804 inhales air from the cavity 111 through the air inlet hole 117, the groove 116, and the second air pipe 113, and reduces the pressure in the cavity 111. Then, under the action of the pressure, the cavity 111 tends to inhale air from the outside through the negative pressure hole 112. The arc plate 808 fits tightly with the side wall of the chain blank, so that the negative pressure hole 112 fits with the chain blank, and then the arc plate 808 and the chain blank are tightly sucked together under the action of pressure; after the bottom wall of the push plate 811 contacts the mounting block 810, the user can start the punching machine 122, and then the output end of the punching machine 122 punches the chain blank through the punching block 123, the slider 124, and the punching head 126. Since the distance between the two holes on different chains may be different, when the holes on the chain blank need to be adjusted, the user can rotate the bidirectional threaded rod 125, and during the rotation of the bidirectional threaded rod 125, the two sliders 124 can be driven to move, and then during the movement of the two sliders 124, the two punching heads 126 can be driven to move, so that holes can be opened for different chain blanks;When the hole drilling is completed, the user can reset the control punch 122, and then retract the output end of the hydraulic rod 809. During the retraction of the output end of the hydraulic rod 809, the mounting block 810 is driven to move upward. During the upward movement of the mounting block 810, the push plate 811 is driven to move upward and disengage from the mounting block 810. At this time, under the action of the fixing rod 902 and the fixing groove 901, the linkage spring 803 cannot drive the mounting plate to reset. Then the output end of the stepping motor 4 drives the rotating rod 5 to rotate. During the rotation of the rotating rod 5, the mounting rod 6 is driven to rotate. The fixing assembly 8 drives the chain blank after the hole is opened to rotate, and during the rotation of the fixing assembly 8, the first magnet 131 is driven to gradually approach the second magnet 132, and when the chain blank is located directly above the collecting slot 133, the distance between the first magnet 131 and the second magnet 132 is the shortest, and then under the action of the repulsive force between the first magnet 131 and the second magnet 132, the second magnet 132 drives the linkage rod 905 to move upward and break away from the side wall of the fixing rod 902, at which time the elastic pad 903 stretches and drives the fixing rod 902 to reset, and At the same time, during the extension of the elastic pad 903, air is sucked from the installation groove 105 through the first air pipe 104, and the pressure in the installation groove 105 is reduced. Then, under the action of the pressure, the limiting rod 101 moves along the installation groove 105 and disengages from the limiting groove 102. At this time, the first spring 806 contracts and drives the connecting plate 805 to reset. During the reset of the limiting rod 101, the groove 116 is disengaged from the second air pipe 113, and the first connecting hole 114 is connected to the second air pipe 113 again. At the same time, the linkage spring 803 contracts and The mounting block 810 is driven to reset. At this time, the space in the mounting cylinder 804 located on the side of the connecting plate 805 close to the first spring 806 can discharge the excess airflow through the exhaust valve 118. Then, during the resetting process of the mounting block 810, the arc plate 808 is driven to reset and disengage from the chain blank through the mounting cylinder 804, the connecting plate 805, and the horizontal rod 807. Then, under the action of gravity, the chain blank falls downward and enters the collection box 134 through the collection groove 133, so that the user does not need to spend time to sort out the chain blank after the hole is opened. ;
