Abstract
Description
Technical Field
[0001] This utility model relates to the field of O-ring production technology, specifically to an O-ring stamping production device. Background Technology
[0002] O-rings are a common type of ring-shaped sealing element, named for their circular cross-section resembling the letter "O". They are widely used in machinery, electronics, automotive, aerospace and other fields to prevent fluid or gas leakage or to isolate external impurities.
[0003] In the hot pressing process of O-rings, trimming is often required. Currently, existing equipment usually lacks an integrated inner and outer ring trimming structure design. When trimming the outer and inner rings of O-rings, different equipment or multiple clamping and adjustment of the mold position are required. For example, after completing the outer ring trimming, the O-ring needs to be removed from the mold and then repositioned and installed on another set of tooling for inner ring trimming. The operation steps are cumbersome and time-consuming, resulting in low production efficiency and difficulty in meeting the needs of large-scale production. In view of this, we propose an O-ring stamping production device. Utility Model Content

[0005] To achieve the above objectives, this utility model proposes an O-ring stamping production device, including an operating table, a support frame connected to the outer wall of the operating table, a stamping device mounted on the support frame, and a lower die positioned directly below the stamping device. The stamping device includes:
[0006] Hydraulic cylinder two is connected to the outer wall of the support frame, and the output end of hydraulic cylinder two is connected to a housing;
[0007] The upper mold has a first cutter on one side and a second cutter on the other side.
[0008] Preferably, a second fixing block is connected to the side wall of the upper mold. The second fixing block has a limit hole. By cooperating with the pin and the first fixing block, the housing and the upper mold can be limited. A handle is connected to the end of the second fixing block.
[0009] Preferably, the outer wall of the lower mold is connected to a guide rod, the guide rod passes through the moving block and is slidably connected to the moving block, and the moving block is passed through by the second fixed block and is rotatably connected to the second fixed block.
[0010] Preferably, a fixing block is connected to the side wall of the housing, the fixing block is provided with a pin, and the end of the pin is provided with an elastic locking block.
[0011] Preferably, the lower mold has a placement groove on its outer wall.
[0012] Preferably, the outer wall of the operating table is provided with a hydraulic cylinder, the output end of the hydraulic cylinder passes through the operating table and is slidably connected to the operating table, and the output end of the hydraulic cylinder is connected to a support block.
[0013] Preferably, a long rod is fixedly connected to the outer wall of the housing, and the long rod passes through the support frame and is slidably connected to the support frame.
[0014] This utility model provides an O-ring stamping production device. It has the following beneficial effects:
[0015] (1) The O-ring stamping production device is designed with a structure that allows for switching the position of the trimming cutter. With cutter one and cutter two set on both sides of the upper mold, and with adjustable support blocks and flexible limiting mechanisms, the trimming operation of the outer and inner rings of the O-ring can be easily realized. In actual production, there is no need to remove the O-ring from the mold and reposition and install it to complete the trimming of the inner and outer rings, which greatly reduces the operation steps and time and significantly improves production efficiency.
[0016] (2) When the inner ring of the O-ring needs to be trimmed, the operator only needs to follow the predetermined steps, control the hydraulic cylinder to drive the support block to move, cooperate with the insertion and removal of the pin and the rotation of the upper mold by the handle, and quickly complete the flipping of the upper mold and repositioning. The whole process does not require complicated tools and cumbersome operation procedures, which greatly reduces the labor intensity of the operator. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] Please see Figures 1-4 This utility model proposes an O-ring stamping production device, including an operating table 1, a support frame 2 connected to the outer wall of the operating table 1, a long rod 21 fixedly connected to the outer wall of the housing 42, the long rod 21 passing through the support frame 2 and slidably connected to the support frame 2, a stamping device on the support frame 2, a lower die 3 directly below the stamping device, and a placement groove 31 opened on the outer wall of the lower die 3 for limiting the O-ring.
[0027] In an embodiment of this utility model, in order to trim the O-ring, the stamping device specifically includes a second hydraulic cylinder 41, which is connected to the outer wall of the support frame 2. The output end of the second hydraulic cylinder 41 is connected to a housing 42. One side of the upper mold 43 is provided with a first cutter 431, which is used to trim the outer ring of the O-ring. The other side of the upper mold 43 is provided with a second cutter 432, which is used to trim the inner ring of the O-ring. A second fixing block 433 is connected to the side wall of the upper mold 43. The second fixing block 433 has a limit hole 434 and a handle 435 is connected to the end of the second fixing block 433.
[0028] Furthermore, a guide rod 32 is connected to the outer wall of the lower mold 3. The guide rod 32 passes through the moving block 33 and is slidably connected to the moving block 33 to improve the movement stability of the moving block 33. The moving block 33 is passed through by the second fixed block 433 and is rotatably connected to the second fixed block 433. A first fixed block 421 is connected to the side wall of the housing 42. A pin 422 is provided inside the first fixed block 421. An elastic locking block 423 is provided at the end of the pin 422 to limit the pin 422 and prevent the pin 422 from falling off.
[0029] Furthermore, the outer wall of the operating table 1 is provided with a hydraulic cylinder 11, the output end of the hydraulic cylinder 11 passes through the operating table 1 and is slidably connected to the operating table 1, the output end of the hydraulic cylinder 11 is connected to a support block 12, and the outer wall of the support block 12 is provided with a limit block to improve the support stability of the moving block 33.
[0030] In this invention, during use, the hot-pressed O-ring is first placed on the outer wall of the lower mold 3. Then, the second hydraulic cylinder 41 is activated. At this time, the second hydraulic cylinder 41 applies a force to the housing 42, causing the housing 42 to drive the upper mold 43 downward, thereby trimming the outer ring of the O-ring. When trimming the inner ring of the O-ring is required, the second hydraulic cylinder 11 is activated first, causing the support block 12 to move upward until the support block 12 contacts the outer wall of the moving block 33. Then, the pin 422 is pulled out from the fixing block 421 and the limiting hole 434, releasing the limitation between the housing 42 and the upper mold 43. Then, hydraulic cylinder 11 drives support block 12 to move downward. During this process, upper mold 43 will move downward synchronously with support block 12 under the action of gravity. When upper mold 43 moves downward a certain distance, hydraulic cylinder 11 is closed. Then, handle 435 is used to rotate upper mold 43 180 degrees. Then, hydraulic cylinder 11 is restarted so that upper mold 43 enters housing 42 again. Then, pin 422 is inserted into fixing block 421 and limiting hole 434 to limit upper mold 43 and housing 42. Then, hydraulic cylinder 41 is started to trim the inner ring of O-ring.
