Description

Technical Field

[0001] The present invention relates to the technical field of pressing and assembling equipment, and particularly to a duct press.

Background Art

[0002] At present, with the development of the automotive industry, some functional components such as ventilation ducts are relatively large and difficult to be integrally formed. Generally, they are assembled by an upper cover and a lower cover. The product is large and has many buckles, resulting in the problem that it is difficult to assemble the upper and lower covers. If manually pressed and installed, there is a phenomenon of missing buckles. Moreover, manual installation can only install a limited number of buckles at the same time and can only be installed from one end to the other end. This method will cause the upper and lower cover plates at the other end to separate when pressing one end of the buckle. When performing the pressing operation at the other end, it is difficult to press, the alignment is inaccurate, and a large force will be generated on the already pressed end, which may cause the problem of buckle breakage. Some existing pressing fixtures have not well solved this problem.

Summary of the Invention

[0003] The purpose of the present invention is to provide a duct press that solves the problems of difficult assembly and easy damage of buckles in existing automotive duct products in view of the defects and deficiencies of the prior art.

The best implementation mode of this embodiment is that the holding device includes a holding frame 51 arranged along the outer periphery of the lower die cavity 2, a first air cylinder 52 and a first air claw 53 installed on the holding frame 51. The first air claw 53 is installed above the holding frame 51, and a sliding plate 54 is provided between the first air claw 53 and the holding frame 51. The first air cylinder 52 is installed below the holding frame 51, and the piston rod of the first air cylinder 52 is connected to the sliding plate 54 to drive the first air claw 53 to move back and forth. In order to facilitate the sliding of the sliding plate 54, a holding slide rail is also provided on the sliding plate 54 and the holding frame 51, and the sliding plate 54 slides back and forth along the holding slide rail.

[0025] Specifically, there are 2 vibrating discs 12 on the workbench 11. A glue nail rack 61 is provided on the upper side of the lower die cavity 2. A glue nail conveying rail 62 is connected between the vibrating disc 12 and the glue nail rack 61. A glue nail installing device is provided on one side of the glue nail conveying rail 62 close to the upper shell, and the glue nail installing device installs the glue nails onto the upper shell. The best implementation mode of this embodiment is that the glue nail installing device includes a "C"-shaped mounting frame 71. The glue nail conveying rail 62 passes through the mounting frame 71 and is connected to the glue nail rack 61. The upper end of the mounting frame 71 is provided with air rods 72 having the same number as the glue nail conveying rails 62. One end of the piston rod of the air rod 72 is connected to a glue nail sliding seat 73. A glue nail cylinder 74 is provided on the glue nail sliding seat 73, and a glue nail gripper 75 for clamping the glue nails is provided at one end of the glue nail cylinder 74. In order to facilitate the sliding of the glue nail sliding seat 73, a sliding seat guide rail 76 for guiding the glue nail sliding seat 73 is provided on the mounting frame 71 on the side close to the air rod 72, and the glue nail sliding seat 73 slides back and forth along the sliding seat guide rail 76.

[0026] More specifically, the downward pressing device drives the lower die cavity 2 to move downward to make the lower shell and the upper shell snap-connect. The best implementation mode of this embodiment is that the downward pressing device includes a downward pressing frame 31 and a downward pressing motor 32 installed on the downward pressing frame 31. A driving gear 33 is provided on the rotating shaft of the downward pressing motor 32. A downward pressing rod 34 is provided on one side of the downward pressing motor 32. The lower end of the downward pressing rod 34 is installed with the lower die cavity 2. A driven gear 35 is sleeved on the downward pressing rod 34. Threads are provided inside the driven gear 35, and threads matching the threads of the driven gear 35 are provided on the outer wall of the downward pressing rod 34. The driving gear 33 meshes with the driven gear 35 to drive the downward pressing rod 34 to move up and down.

[0027] More specifically, a load-bearing plate 8 is provided between the lower pressing rod 34 and the lower mold cavity 2 , and four load-bearing cylinders 81 are provided between the load-bearing plate 8 and the workbench 11 . The load-bearing cylinders 81 move synchronously with the lower pressing rod 34 .

[0028] The working principle of the present invention is as follows:

[0029] First, the upper shell is placed on the upper die cavity 4 and the lower shell is placed on the lower die cavity 2. The start switch is pressed, and the first cylinder 52 is activated, pushing the slide 54 toward the lower shell, thereby driving the first air claw 53 to contact the claw. The claw is always directly below the latch hole of the upper shell. Then, the pressing device is activated, and the shaft of the pressing motor 32 drives the driving gear 33 to rotate. The driving gear 33 engages with the driven gear 35. Because the driven gear 35 has a thread inside, the outer wall of the pressing rod 34 has a thread that matches the thread of the driven gear 35. The driving gear 33 and the driven gear 35 engage, thereby driving the pressing rod 34 to move downward, thereby driving the lower die cavity 2 downward. At the same time, the four bearing cylinders 81 move downward synchronously with the pressing rod. When the claw of the lower shell inserts into the buckle of the upper shell, the pressing motor 32 pauses, and the first cylinder 52 resets, thereby driving the first air claw 53 to reset. After the first cylinder 52 resets, the pressing motor 32 is restarted, completely pressing the upper shell and the lower shell together. Then the glue nail clamp 75 of the glue nail installation device clamps the glue nails that have been pre-screened by the vibration plate 12, the air rod 72 pushes the glue nail slide 73 to move toward the upper shell, and then the glue nail cylinder 74 pushes the glue nail clamp 75 to move downward, thereby driving the glue nails into the upper shell.

[0030] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
