Description

Technical Field

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

[0002] A chain is generally a metal link or ring, mostly used for mechanical transmission and traction; a chain-shaped object used to block a traffic passage (such as in a street, at the entrance of a river or a harbor), and a chain for mechanical transmission.

[0003] Currently, in the processing of metal chains, it is necessary to perform hole opening processing on metal chain blanks, that is, punching thin metal plates. Usually, it is necessary to perform feeding of metal chain blanks, punching, grinding processing, and discharging. Traditional chain processing hole opening methods usually use manual or low-automation equipment, which is cumbersome to operate, has a large intensity, low efficiency, and is prone to uneven hole opening sizes and position deviations, resulting in the need for repeated rework, seriously affecting the hole opening efficiency.

[0004] In response to the above problems, some solutions have also been given in the prior art. For example, Chinese invention application with the publication number CN118371592A discloses a metal chain processing hole opening machine. By setting a punching mechanism, when the moving plate moves down, it can drive the punching block to move down. First, the metal chain blank is pressed tightly by the second pressing frame to ensure the stability of the metal chain blank during the hole opening process, which can ensure the hole opening quality and improve the hole opening efficiency; however, during use, the chain blank is often placed manually on the top wall of the workbench. Due to certain errors in manual placement, it is prone to uneven hole opening sizes and position deviations, resulting in the need for repeated rework. Although the prior art has improved it by restricting the chain blank through the limiting groove, when opening holes for chain blanks of different sizes, it takes time for the user to replace different hole opening machines, which still seriously affects the hole opening efficiency. Summary of the Invention

[0005] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a chain processing hole opening machine, which can achieve the purpose of improving the hole opening efficiency.

[0006] To solve the above problems, the present invention adopts the following technical solutions.

A hydraulic rod is mounted on the top plate. An installation block is fixedly mounted on the output end of the hydraulic rod. A stamping component is provided on the installation block. A pushing plate is fixedly mounted on the installation block. An inclined groove is formed on the bottom wall of the pushing plate. And a limiting component for limiting the movement of the sliding plate is provided on the pushing plate.

[0009] Further, the limiting component includes a fixed groove formed on the side wall of the sliding groove. A horizontal groove is formed on the sliding plate. A fixed rod is slidably mounted in the horizontal groove. An elastic pad is commonly fixed between the fixed rod and the horizontal groove. A linkage groove is formed on the fixed rod. A linkage rod extending into the linkage groove is vertically slidably mounted on the sliding plate. A linkage component cooperating with the elastic pad is provided on the connecting plate.

[0010] Further, the linkage component includes an installation groove formed on the connecting plate. A limiting rod is slidably and sealingly mounted in the installation groove. A limiting groove is formed on the inner wall of the installation cylinder. A cavity is formed on the elastic pad. A first air pipe communicating with the installation groove is inserted into the cavity.

[0011] Further, a cavity is formed on the arc-shaped plate. A negative pressure hole is formed on the cavity. A second air pipe is formed on the cavity. A first communication hole communicating with the second air pipe is formed on the limiting rod. A second communication hole communicating with the first communication hole is formed on the connecting plate.

[0012] Further, a groove communicating with the second air pipe is formed on the side wall of the connecting plate. An air inlet hole communicating with the second air pipe is formed on the first communication hole. An exhaust valve with an output end communicating with the outside is inserted into the installation cylinder.

[0013] Further, the stamping component includes a stamping machine mounted on the installation block. A vertical groove is formed on the installation block. A stamping block fixedly connected to the output end of the stamping machine is slidably mounted in the vertical groove. An adjustment groove is formed on the stamping block. Sliders are symmetrically and slidably mounted in the adjustment groove. A bidirectional threaded rod is rotatably mounted on the stamping block. And the bidirectional threaded rod is in threaded cooperation with the sliders. A stamping head is mounted on the bottom wall of the slider.

[0014] Further, a first magnet is embedded on the linkage rod, and a second magnet that repels the first magnet is embedded on the top wall of the workbench. A collection cavity is formed on the workbench, and a collection box is slidably installed in the collection cavity. A collection groove is formed on the top wall of the collection cavity.

[0015] Further, a stamping groove is formed on the top wall of the workbench, and a waste material groove communicating with the stamping groove is formed on the side wall of the workbench. A waste material box is movably installed in the waste material groove.

[0016] Further, one end of the fixed rod close to the fixed groove is beveled.

[0017] Further, a sliding rod is rotatably installed on the linkage rod.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0019] (1) In this solution, through the cooperation of the push plate and the linkage rod, when the installation block drives the stamping component to move downward for punching, the push plate can drive the fixing component to straighten the chain blank, and make the chain blank located directly below the stamping component, avoiding errors in the stamping holes and affecting the production efficiency. At the same time, the cooperation of the installation cylinder, the first spring, the horizontal rod, and the arc plate can clamp chain blanks of different sizes, so that the user does not need to spend time replacing the punching machine, which improves the production efficiency.

[0020] (2) In this solution, through the cooperation of the fixed rod and the limiting rod, the positions of the installation cylinder and the connecting plate can be limited, so that the horizontal rod on the connecting plate can limit the arc plate, avoiding the chain blank driving the connecting plate to move through the arc plate and the horizontal rod during the punching process, which affects the punching effect and leads to the need for rework, further improving the production efficiency.

[0021] (3) In this solution, by opening the cavity, when the limiting rod moves, it drives the groove to move. When the limiting rod is inserted into the limiting groove, the groove communicates with the second air pipe. At this time, the space of the installation cylinder on the side of the connecting plate close to the first spring inhales 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 the pressure, the cavity has a tendency to inhale air from the outside through the negative pressure hole. Since the arc plate is in close contact with the side wall of the chain blank at this time, the negative pressure hole is in close contact with the chain blank, and then under the action of the pressure, the arc plate and the chain blank are tightly sucked together, thereby improving the punching accuracy of the chain blank, that is, reducing the probability of rework of the reworked chain blank, and further improving the production efficiency.

[0039] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0040] Please refer to Figures 1 to 8 , a chain processing hole-opening machine, including a workbench 1, an installation frame 2 is fixedly installed on the top wall of the workbench 1, a top plate 3 is fixedly installed on the installation frame 2, a stepping motor 4 is installed on the workbench 1, a rotating rod 5 is fixedly installed on the output end of the stepping motor 4, installation rods 6 are uniformly fixedly installed on the rotating rod 5, and a fixing component 8 is arranged on the installation rod 6;

[0041] The fixing component 8 includes sliding grooves 801 symmetrically opened on the installation rod 6, a sliding plate 802 is slidably installed in the sliding groove 801, a linkage spring 803 is jointly installed between the sliding plate 802 and the sliding groove 801, an installation cylinder 804 is fixedly installed on the side wall of the sliding plate 802, a connecting plate 805 is slidably installed in the installation cylinder 804, and a first spring 806 is jointly installed between the installation cylinder 804 and the connecting plate 805. A horizontal rod 807 is fixedly installed on the side wall of the connecting plate 805, an arc-shaped plate 808 is fixedly installed at the end of the horizontal rod 807 away from the connecting plate 805, a hydraulic rod 809 is installed on the top plate 3, an installation block 810 is fixedly installed on the output end of the hydraulic rod 809, a punching component 12 is arranged on the installation block 810, a push plate 811 is fixedly installed on the installation block 810, an inclined groove 812 is opened on the bottom wall of the push plate 811, and a limiting component 9 for limiting the movement of the sliding plate 802 is arranged on the push plate 811.

[0042] The limiting component 9 includes a fixing groove 901 opened on the side wall of the sliding groove 801, a horizontal groove is opened on the sliding plate 802, a fixing rod 902 is slidably installed in the horizontal groove, an elastic pad 903 is jointly fixed between the fixing rod 902 and the horizontal groove, a linkage groove 904 is opened on the fixing rod 902, a linkage rod 905 extending into the linkage groove 904 is vertically slidably installed on the sliding plate 802, and a linkage component 10 cooperating with the elastic pad 903 is arranged on the connecting plate 805.

[0043] The linkage assembly 10 includes an installation groove 105 formed in the connecting plate 805. A limiting rod 101 is slidably and sealingly installed in the installation groove 105. A limiting groove 102 is formed on the inner wall of the installation cylinder 804. A cavity 103 is formed in the elastic pad 903. A first air pipe 104 communicating with the installation groove 105 is inserted into the cavity 103.

[0044] During use, the user can place the chain blank between the arc-shaped plates 808 of the two limiting rods 101. Then, the output end of the hydraulic rod 809 extends and drives the installation block 810 to move downward. During the downward movement of the installation block 810, the push plate 811 is driven to move downward. Then, during the downward movement of the push plate 811, the inclined groove 812 gradually contacts the sliding plate 802 and applies a thrust to the sliding plate 802. Then, under the action of the thrust, the sliding plate 802 moves along the sliding groove 801. At this time, the linkage spring 803 is stretched and has a tendency to recover. And during the movement of the sliding plate 802, the installation cylinder 804 is driven to move. Then, during the movement of the installation cylinder 804, the arc-shaped plate 808 is driven to gradually contact the chain blank and apply a thrust to the chain blank through the connecting plate 805 and the horizontal rod 807. Then, under the thrust of the two arc-shaped plates 808, the chain blank can be moved downward below the stamping assembly 12. At the same time, under the action of the arc surface of the arc-shaped plate 808, the chain blank can be straightened, so as to ensure that the chain blank moves to directly below the stamping assembly 12, avoiding errors in stamping holes and affecting production efficiency. And after the installation cylinder 804 drives the arc-shaped plate 808 to clamp the chain blank through the connecting plate 805 and the horizontal rod 807, as the sliding plate 802 drives the installation cylinder 804 to continue to move, at this time, the arc-shaped plate 808 drives the connecting plate 805 to slide in the installation cylinder 804 through the horizontal rod 807 and stretches the first spring 806, so as to clamp chain blanks of different sizes, thus eliminating the need for the user to spend time replacing the hole punching machine, which plays a role in improving production efficiency.

[0045] During the process of the inclined groove 812 of the push plate 811 driving the installation block 810 to move, the bottom wall of the push plate 811 gradually contacts the linkage rod 905 and applies a downward thrust to the linkage rod 905. Then, under the action of the thrust, the linkage rod 905 moves downward. And during the downward movement of the linkage rod 905, it gradually contacts the linkage groove 904 of the fixed rod 902 and applies a thrust to the linkage groove 904. Then, under the action of the thrust, the fixed rod 902 moves along the horizontal groove. And after the inclined groove 812 of the push plate 811 is disengaged from the installation block 810, the fixed rod 902 is inserted into the fixed groove 901, so as to limit the position of the installation block 810 and prepare for subsequent automatic unloading.

[0046] During the process of the linkage rod 905 driving the fixed rod 902 to insert into the fixed slot 901, the elastic pad 903 is squeezed and has a tendency to recover. And during the process of the elastic pad 903 being squeezed, the air flow in the cavity 103 flows through the first air pipe 104 into the installation slot 105, and the pressure in the installation slot 105 increases. Then, under the action of the pressure, the limit rod 101 slides along the installation slot 105. And when the fixed rod 902 inserts into the fixed slot 901, the limit rod 101 inserts into the limit slot 102, thus preventing 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, which affects the punching effect and leads to the need for rework, and further improving the production efficiency.

[0047] As Figure 3 、 Figure 4 shown, a cavity 111 is provided on the arc plate 808, a negative pressure hole 112 is provided on the cavity 111, a second air pipe 113 is provided on the cavity 111, a first communication hole 114 communicating with the second air pipe 113 is provided on the limit rod 101, and a second communication hole 115 communicating with the first communication hole 114 is provided on the connecting plate 805.

[0048] A groove 116 communicating with the second air pipe 113 is provided on the side wall of the connecting plate 805, and an air inlet hole 117 communicating with the second air pipe 113 is provided on the first communication hole 114. An exhaust valve 118 with an output end communicating with the outside is inserted on the installation cylinder 804.

[0049] By adopting the above technical solution, during the process of the connecting plate 805 moving along the installation cylinder 804 and stretching the first spring 806, the pressure in the space of the installation cylinder 804 on the side of the connecting plate 805 close to the first spring 806 decreases. At this time, the space of the installation cylinder 804 on the side of the connecting plate 805 close to the first spring 806 has a tendency to suck air from the outside. Then, during the movement of the limit rod 101, the groove 116 is driven to move. When the limit rod 101 inserts into the limit slot 102, the groove 116 communicates with the second air pipe 113. At this time, the space of the installation cylinder 804 on the side of the connecting plate 805 close to the first spring 806 sucks air from the cavity 111 through the air inlet hole 117, the groove 116, and the second air pipe 113, and the pressure in the cavity 111 decreases. Then, under the action of the pressure, the cavity 111 has a tendency to suck air from the outside through the negative pressure hole 112. Since the arc plate 808 is in close contact with the side wall of the chain blank at this time, the negative pressure hole 112 is in contact with the chain blank. Then, under the action of the pressure, the arc plate 808 and the chain blank are tightly sucked together, thus improving the punching accuracy of the chain blank, that is, reducing the probability of rework of the reworked chain blank, and further improving the production efficiency.

[0050] 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 communication hole 115, the first communication hole 114, and the second air pipe 113, and then blows towards the side wall of the chain blank through the negative pressure hole 112 on the cavity 111, so as to clean the dust particles adhering to the side wall of the chain blank, ensuring that the arc-shaped plate 808 can be closely attached to the chain blank.

[0051] As Figure 5 , Figure 6 shown, the stamping assembly 12 includes a stamping machine 122 installed on the mounting block 810. A vertical groove is provided on the mounting block 810. A stamping block 123 fixedly connected to the output end of the stamping machine 122 is slidably installed in the vertical groove. An adjustment groove is provided on the stamping block 123. Sliders 124 are symmetrically and slidably installed in the adjustment groove. A bidirectional threaded rod 125 is rotatably installed on the stamping block 123, and the bidirectional threaded rod 125 is in threaded cooperation with the sliders 124. A stamping head 126 is installed on the bottom wall of the slider 124.

[0052] 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 stamping machine 122, and then the output end of the stamping machine 122 performs stamping operations on the chain blank through the stamping block 123, the sliders 124, and the stamping head 126. Since the distance between 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 during the movement of the two sliders 124, the two stamping heads 126 can be driven to move, so as to open holes in different chain blanks, further improving the production efficiency.

[0053] As Figure 2 , Figure 7 shown, a first magnet 131 is embedded on the linkage rod 905, a second magnet 132 that repels the first magnet 131 is embedded on the top wall of the workbench 1, and a collection cavity is provided on the workbench 1. A collection box 134 is slidably installed in the collection cavity, and a collection groove 133 is provided on the top wall of the collection cavity.

[0054] 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.

[0055] 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 .

[0056] 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.

[0057] As Figure 3 shown, one end of the fixing rod 902 close to the fixing groove 901 is an inclined surface.

[0058] By adopting the above technical solution, during the process of inserting the fixing rod 902 into the fixing groove 901, by making one end of the fixing rod 902 close to the fixing groove 901 be an inclined surface, it is convenient for the fixing rod 902 to be inserted into the fixing groove 901.

[0059] As Figure 8 shown, a sliding rod 16 is rotatably installed on the linkage rod 905.

[0060] By adopting the above technical solution, during the process of the linkage rod 905 pushing one end of the fixing rod 902 through the inclined groove 812, by providing the sliding rod 16, the sliding friction between the linkage rod 905 and the inclined groove 812 can be converted into the rolling friction between the sliding rod 16 and the inclined groove 812, thereby reducing the resistance when the linkage rod 905 pushes the fixing rod 902, and also reducing the resistance when the first magnet 131 drives the linkage rod 905 to move upward through the second magnet 132, thus improving the stability of the device operation.

[0061] Usage method: During use, the operator can place the chain blank between the arc-shaped plates 808 of the two limit rods 101. Then, the output end of the hydraulic rod 809 extends and drives the mounting block 810 to move downward. During the downward movement of the mounting block 810, the push plate 811 is driven to move downward. Then, during the downward movement of the push plate 811, the inclined groove 812 gradually contacts the sliding plate 802 and applies a thrust to the sliding plate 802. Then, under the action of the thrust, the sliding plate 802 moves along the sliding groove 801. At this time, the linkage spring 803 is stretched and has a tendency to recover. And during the movement of the sliding plate 802, the mounting cylinder 804 is driven to move. Then, during the movement of the mounting cylinder 804, the arc-shaped plate 808 is driven to gradually contact the chain blank and apply a thrust to the chain blank through the connecting plate 805 and the horizontal rod 807. Then, under the thrust of the two arc-shaped plates 808, the chain blank can be moved downward below the punching assembly 12. At the same time, under the action of the arc surface of the arc-shaped plate 808, the chain blank can be aligned, so as to ensure that the chain blank moves directly below the punching assembly 12, avoiding errors in punching holes and affecting production efficiency. And after the mounting cylinder 804 drives the arc-shaped plate 808 to clamp the chain blank through the connecting plate 805 and the horizontal rod 807, as the sliding plate 802 drives the mounting cylinder 804 to continue to move, at this time, the arc-shaped plate 808 drives the connecting plate 805 to slide in the mounting cylinder 804 through the horizontal rod 807 and stretches the first spring 806, so as to clamp chain blanks of different sizes; During the process of the linkage rod 905 driving the fixed rod 902 to insert into the fixed groove 901, the elastic pad 903 is squeezed and has a tendency to recover. And during the squeezing of the elastic pad 903, the air flow in the cavity 103 flows through the first air pipe 104 into the mounting groove 105, and the pressure in the mounting groove 105 increases. Then, under the action of the pressure, the limit rod 101 slides along the mounting groove 105. And when the fixed rod 902 is inserted into the fixed groove 901, the limit rod 101 is inserted into the limit groove 102, so as to prevent the chain blank from driving the connecting plate 805 to move through the arc-shaped plate 808 and the horizontal rod 807 during the punching process and affecting the punching effect;During the process of the connecting plate 805 moving along the mounting cylinder 804 and stretching the first spring 806, the pressure in the space of the mounting cylinder 804 on the side of the connecting plate 805 close to the first spring 806 decreases. At this time, the space of the mounting cylinder 804 on the side of the connecting plate 805 close to the first spring 806 has a tendency to suck air from the outside. Then, during the movement of the limiting rod 101, the groove 116 is driven to move. When the limiting rod 101 is inserted into the limiting groove 102, the groove 116 communicates with the second air pipe 113. At this time, the space of the mounting cylinder 804 on the side of the connecting plate 805 close to the first spring 806 sucks air from the cavity 111 through the air inlet hole 117, the groove 116, and the second air pipe 113, and the pressure in the cavity 111 decreases. Then, under the action of the pressure, the cavity 111 has a tendency to suck air from the outside through the negative pressure hole 112. Since the arc-shaped plate 808 is in close contact with the side wall of the chain blank at this time, the negative pressure hole 112 is in contact with the chain blank. Then, under the action of the pressure, the arc-shaped plate 808 and the chain blank are tightly sucked together. After the bottom wall of the push plate 811 contacts the mounting block 810, the user can start the stamping machine 122. Then, the output end of the stamping machine 122 performs stamping operations on the chain blank through the stamping block 123, the slider 124, and the stamping head 126. Since the distance between 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. Then, during the movement of the two sliders 124, the two stamping heads 126 can be driven to move, so as to punch holes in 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. ;
