Detailed Implementation

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0025] In this utility model, unless otherwise stated, directional terms such as "up, down, left, right, front, back, inside, outside" in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as a limitation on the term.

[0026] See Figure 1-4The riveting machine mold frame structure 1 shown includes a bottom template 101 and an electric cylinder base plate 103 arranged in parallel. Two pairs of columns 102 distributed front and rear are arranged between the bottom template 101 and the electric cylinder base plate 103. Two parallel linear slide rails 105 extending front and rear are arranged in the middle of the bottom template 101. A connecting slider 115 is slidably arranged on the linear slide rails 105. A bushing 111 is arranged between the two columns 102 at the front end of the bottom template 101 and on the outer side of the two linear slide rails 105. An upper through hole 114 is arranged on the inner side of the two linear slide rails 105. A cylinder mounting plate 108 is arranged at the rear end of the bottom template 101.

[0027] See Figure 5 The assembly structure diagram of the bushing riveting machine shown is as follows: In the assembly structure of the bushing riveting machine, the movable lower die structure 2 is mounted on the linear slide rail 105 via multiple connecting sliders 115. A cylinder 8 is mounted on the cylinder mounting plate 108, and the cylinder 8 is connected to the movable lower die structure 2, enabling it to switch between the bushing pressing station and the riveting station. The guide die assembly 5 has a portal-shaped structure, spanning above the bushing pressing station. Guide rods on both sides slide and extend within corresponding bushings 111. The movable lower die structure 2 is provided with a lower die groove for positioning the workpiece, and the guide die assembly 5 is correspondingly provided with an upper die groove for positioning the workpiece. After part 5 moves down, the lower mold groove and the upper mold groove can close to position the workpiece. Then, the bushing to be pressed is placed in the positioning through hole on the upper mold groove to complete the preparation work. Then, the bushing pressing mold assembly 3 guides and slides down, and the corresponding pressure rod presses the bushing into the workpiece. Since the flange at the bottom of the bushing needs to be pressed below the hole of the workpiece, the upper end of the bushing needs to be overpressed. After the bushing is overpressed, the upper top shaft on the reverse pressing mechanism 6 is used to push the overpressed bushing back to the normal position, so that the upper flange of the bushing is pressed out. Finally, the lower mold structure 2 is moved to the riveting station by the cylinder 8 pulling back. The flanging pressing mold assembly 4 guides and slides down to press the riveting.

[0028] When the workpiece is an automotive shock absorber, the main body of the automotive shock absorber is supported by the installed auxiliary support component 7, and the lifting ring of the automotive shock absorber is positioned between the upper and lower mold slots.

[0029] Therefore, the riveting machine mold frame structure 1 of this utility model uses a linear slide rail 105 and connecting sliders 115 on the linear slide rail 105 to install the movable lower mold structure 2, so that the movable lower mold structure 2 can slide on the linear slide rail 105. A cylinder mounting plate 108 is provided at the rear end of the bottom template 101, providing a mounting position for installing and pushing the movable lower mold structure 2, which facilitates the switching of the movable lower mold structure 2 between the bushing pressing station and the riveting station. Two pairs of front and rear distributed columns 102 are provided. The two columns 102 at the front end are used to guide the sliding of the bushing pressing mold assembly 3, and the two columns 102 at the rear end are used to guide the sliding of the flanging riveting mold assembly 4. The upper top through hole 114 is used to push the over-pressed bushing to the normal position through the upper top shaft on the reverse pressing mechanism 6. The two bushings 111 are used to guide the sliding of the guiding pressing mold assembly 5.

[0030] In this embodiment, a front-end electric cylinder shaft hole 113 is provided between the two columns 102 at the front end of the electric cylinder base plate 103; a plurality of first screw holes 117 for mounting the front-end electric cylinder 9 are provided around the front-end electric cylinder shaft hole 113 on the electric cylinder base plate 103.

[0031] With this setup, the front-end electric cylinder 9 is mounted on the electric cylinder base plate 103 by screws corresponding to the first screw hole 117, and its cylinder shaft passes through the front-end electric cylinder shaft hole 113 to connect with the bushing press-fit mold assembly, providing vertical reciprocating movement of the bushing press-fit mold assembly.

[0032] In this embodiment, a rear-end electric cylinder shaft hole 112 is provided between the two columns 102 at the rear end of the electric cylinder base plate 103; a plurality of second screw holes 118 for mounting the rear-end electric cylinder 10 are provided around the rear-end electric cylinder shaft hole 112 on the electric cylinder base plate 103. With this arrangement, the front-end electric cylinder 9 is mounted on the electric cylinder base plate 103 by screws corresponding to the second screw holes 118, and its cylinder shaft passes through the rear-end electric cylinder shaft hole 112 to connect with the flange pressing and riveting die assembly 4, providing vertical reciprocating movement of the pressing and fitting die assembly.

[0033] In this embodiment, both the upper and lower ends of the column 102 are provided with studs with shoulders, and locking nuts 104 are provided on the outside of the studs. With this arrangement, after the two ends of the column 102 are inserted into the bottom template 101 and the electric cylinder base plate 103 respectively, they are locked by the locking nuts 104, which facilitates assembly and disassembly.

[0034] In this embodiment, a set of buffer mechanisms is provided on the bottom template 101 at the outer positions of the two linear slide rails 105. The buffer mechanism includes two symmetrically arranged mounting seats 106, and hydraulic buffers 110 are mounted on the two mounting seats 106 on the same side by set screws 109. The buffer contact ends of the two hydraulic buffers 110 on the same side are arranged opposite to each other. Through the buffer mechanism, a limit block is provided on the moving lower mold structure 2. The limit block moves between the two hydraulic buffers 110 arranged in front and behind, and is buffered and stopped after impacting the corresponding hydraulic buffer 110.

[0035] In this embodiment, stop blocks 107 are provided on the bottom template 101 at both ends of the linear slide rail 105. The stop blocks 107 stop the linear slide rail 105 at both ends to prevent the connecting slider 115 from derailing.
