DETAILED DESCRIPTION

[0025] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0026] With the widespread application of electronic devices, the output of electronic devices often falls short of demand. Electronic devices can include desktop computers, laptop computers, mobile phones, tablet computers and other communication devices with terminal transmission functions. Taking desktop computers as an example, desktop computers generally include servers, and servers generally include chassis. In actual production, the rear window needs to be riveted to the chassis base. It can be understood as: the left and right sides of the rear window and the bottom are riveted to the chassis base. Specifically, the left and right sides are generally riveted by hanging riveting, and the bottom is riveted by positive riveting, which will increase costs and cause significant operation and quality problems.

[0027] The existing riveting device requires three sets of dies for the riveting of the rear window, one for the left side, one for the right side, and one for the bottom, which are completed at three workstations, resulting in high mold costs. In addition, the labor cost is high, with two people operating one station, one person holding the product by hand, and one person assisting in placing the product and operating the machine. In addition, the quality of the riveted products is poor: the personnel hold the product by hand, the product positioning is unstable, and poor riveting is prone to occur; the chassis base is heavy (10-15kg), and two people place the product on the bottom die inside the punch press, which is prone to collision and injury; finally, the operation is unsafe and difficult to operate. The design of this hanging riveting die needs to block the safety induction fiber operation of the punch press; the chassis base is heavy (10-15kg), and two people operate to stuff the product into the bottom die inside the punch press during riveting, which is difficult to operate.

[0028] To alleviate the above problems, refer to Figure 1-Figure 4 The embodiment of the present disclosure provides a riveting device 001, which is applied to mold processing equipment. Specifically, the riveting device 001 includes a lower mold assembly 10, and the lower mold assembly 10 includes a pull-out bottom mold component 101. The pull-out bottom mold component 101 is mainly used to facilitate one person to operate, pull in and out the workpiece 50 to be processed, and can perform the riveting process in a stable state.

[0029] Specifically, the pull-out bottom mold component 101 includes a fixed frame 1011 and a movable slide 1012. The movable slide 1012 is detachably assembled with the fixed frame 1011. Furthermore, the movable slide 1012 is slidably matched with the fixed frame 1011 along its own length direction. Specifically, the fixed frame 1011 has a slide track 1013, and the movable slide 1012 is slidably matched with the slide track 1013, so as to realize the reciprocating sliding of the movable slide 1012 relative to the fixed frame 1011.

[0030] In addition, the lower mold assembly 10 further includes a self-locking member 1014, which is used to firmly assemble the movable slide 1012 and the fixed frame 1011, and then realize the riveting action on the workpiece 50 when the two are assembled. Specifically, the self-locking member 1014 is installed on one side of the fixed frame 1011, and illustratively, the self-locking member 1014 is installed on the bottom of the fixed frame 1011. At the same time, a limiting groove 10121 is set on one side of the movable slide 1012, and illustratively, the limiting groove 10121 is located at the bottom of the movable slide 1012. Furthermore, the self-locking member 1014 is configured to have the function of being retractable and movable toward the movable slide 1012 along the width direction of the fixed frame 1011. During the reciprocating movement of the movable slide 1012, the self-locking member 1014 can be engaged with or disengaged from the limiting groove 10121, thereby achieving a firm connection or mutual separation between the movable slide 1012 and the fixed frame 1011. When the two are firmly connected, a riveting process can be performed. After the riveting process is completed, the two are separated from each other, the completed workpiece is removed, and the next workpiece to be processed 50 is replaced, and the whole process is convenient to operate.

[0031] Considering that the self-locking member 1014 can be disengaged and engaged in the limiting groove 10121, specifically, the self-locking member 1014 includes a handle 10141, a positioning member 10142, a limiting block 10143 and a return spring 10144, wherein the positioning member 10142 penetrates the handle 10141 and positions the handle 10141 at the first position of the fixed frame 1011, and the first position here can be set according to actual needs without specific restrictions. A first groove 10111 is formed at the first position, and the groove opening of the first groove 10111 is set toward the movable slide 1012, and the limiting block 10143 is embedded in the first groove 10111 and connected to the rear end of the positioning member 10142, and the rear end of the positioning member 10142 is an end extending into the fixed frame 1011. The return spring 10144 is arranged between the limiting block 10143 and the inner bottom wall of the first groove 10111. In this way, the positioning member 10142 can be reset and engaged in the limiting groove 10121 under the action of the reset spring 10144. When the reset spring 10144 returns to the initial position, the positioning member 10142 and the limiting block 10143 still maintain a stable assembly.

[0032] Considering the riveting process of at least three sides of the workpiece 50 to be processed, the riveting device 001 provided in the embodiment of the present disclosure also includes an upper mold assembly 20, which is matched with the lower mold assembly 10 to form a mold for the three-side riveting process. The upper mold assembly 20 includes an inner pin 21, a first inner slider 22 and a second inner slider 23 located on both sides of the inner pin 21. When the inner pin 21 moves from top to bottom, the inner pin 21 pushes the first inner slider 22 and the second inner slider 23 to move in a direction away from the inner pin 21, so that the first inner slider 22 and the second inner slider 23 can push the two sides of the server chassis to the sides, and perform the riveting process on the two sides of the server chassis in combination with the lower mold assembly 10.

[0033] Considering the riveting cooperation between the lower mold assembly 10 and the upper mold assembly 20 on both sides of the chassis, the lower mold assembly 10 also includes a first outer slider 11 and a second outer slider 12. When the mold is closed, the first outer slider 11 is arranged close to the first inner slider 22, and the second outer slider 12 is arranged close to the second inner slider 23. Specifically, the first outer slider 11 and the second outer slider 12 are respectively arranged on the outside of the movable slide 1012. When the mold is closed, one side edge of the workpiece 50 to be processed is clamped between the first inner slider 22 and the first outer slider 11, and they are pressed and riveted, and the other side edge of the workpiece 50 to be processed is clamped between the second inner slider 23 and the second outer slider 12, and they are pressed and riveted.

[0034] Considering the sliding fit of the movable slide 1012 relative to the fixed frame 1011, specifically, a pulley structure 1015 rolling along the length direction of the movable slide 1012 is provided between the bottom of the movable slide 1012 and the fixed frame 1011, and a slide groove slidingly matched with the pulley structure 1015 is provided on the fixed frame 1011, and slide rails 1013 are provided on both sides of the movable slide 1012. Exemplarily, the slide rails 1013 are provided on the top surface of the fixed frame 1011, and the slide rails 1013 are formed in the protrusions on the top surface of the fixed frame 1011. This allows the movable slide 1012 to slide back and forth above itself relative to the fixed frame 1011.

[0035] Considering the insertion to push the first inner slider 22 and the second inner slider 23 to both sides, the inner plug pin 21 is set as the following convex block structure. Specifically, the inner plug pin 21 includes an upper structure 211 and a lower structure 212. The outer diameter of the upper structure 211 is larger than the outer diameter of the lower structure 212, and a step structure is formed between the two. The first inner slider 22 and the second inner slider 23 are symmetrically arranged, and the two are constructed such that the upper outer diameter is smaller than the lower outer diameter on the side close to the inner plug pin 21. In this way, when the inner plug pin 21 is moved from the upper and lower membranes to between the first inner slider 22 and the second inner slider 23, when the upper structure 211 contacts the inner sliders on both sides, due to the setting of the step structure, the upper structure 211 pushes the inner sliders to both sides again, so as to further realize the pushing of the inner sliders on both sides to the riveting positions on the two sides of the chassis.

[0036] Furthermore, considering the bidirectional retracting pressure on both sides of the chassis, the upper mold assembly 20 also includes a first external pin 24 and a second external pin 25, which are respectively arranged on both sides of the upper mold assembly 20. At the same time, the lower mold assembly 10 also includes a first fixed block 13, a second return spring 16 arranged horizontally on the first fixed block 13, a second fixed block 15, and a second return spring 16 arranged horizontally on the second fixed block 15. When closing the film, the first external pin 24 is clamped between the first fixed block 13 and the first outer slider 11, and the second return spring 16 pushes the first outer slider 11 to make the force toward the first inner slider 22, and the first inner slider 22 and the first outer slider 11 clamp one side of the chassis for the riveting process. At the same time, the second external pin 25 is clamped between the second fixed block 15 and the second outer slider 12, and the second return spring 16 pushes the second outer slider 12 to make the force toward the second inner slider 23, and the second inner slider 23 and the second outer slider 12 clamp the other side of the chassis for the riveting process. In this way, the riveting of both sides can be achieved simultaneously under the mold closing action of the same riveting device 001.

[0037] In summary, for the structural stability of the overall riveting device 001, the riveting device 001 also includes a top cover 30 and a base 40, the upper mold assembly 20 mentioned above is installed on the top cover 30, and the lower mold assembly 10 mentioned above is installed on the base 40. The lower mold assembly 10 is static and motionless, the upper mold assembly 20 is located above the lower mold assembly 10, and moves relative to the lower mold assembly 10 after the corresponding position. In addition, under the joint action of the movable slide 1012, the fixed frame 1011 and the self-locking member 1014 in the lower mold assembly 10, the riveting action on the rear side of the chassis can be achieved between the movable slide 1012 and the back pressure block. It should be pointed out that the back pressure block includes but is not limited to a part of the riveting device 001 of the embodiment of the present disclosure.

[0038] The disclosed embodiment also provides a mold processing equipment, which includes the above-mentioned riveting device 001, and the riveting device 001 is located at one of the workstations in the mold processing process. The riveting device 001 is configured to perform side riveting actions on the workpiece 50 to be processed when the mold is closed, and can achieve all the effects of the above-mentioned riveting device 001, which will not be repeated here.
