The utility model fixes the slide rod at the upper end of the support seat, an oil storage tank is provided in the slide rod, and oil is supplied into the oil storage tank. When the driving block drives the slide rod to slide on the slide rod, the lubricating oil in the oil storage tank seeps out through the cotton core in the oil outlet hole to lubricate the support hole, thereby reducing the wear between the slide rod and the slide rod and improving the service life of the device.

[0004] The device stores oil and leaks oil by opening an oil storage tank in the slide rod, thereby reducing the wear between the slide rod and the slider.

The damage to the contact surface between the inclined surface of the slider and the inclined wedge body caused by long-term friction also needs to be considered. Therefore, a compact inclined wedge is urgently needed to solve the above problems. Utility Model Content

[0029] In this embodiment, lubricating oil is dripped on the contact surface between the inclined block 26 and the inclined wedge body 24 through the protective mechanism 3, so as to reduce the damage to the contact surface between the inclined block 26 and the inclined wedge body 24 caused by the friction between the two due to the long-term connection, thereby improving the service life of the internal components of the pressing mechanism 2. The base 1 contacts the ground to support the discharge table 21, and the discharge table 21 is used to place the material. The top of the material is provided with a pressing plate 22 to limit the material, and the two ends of the material are stamped and bent in cooperation with the stamping plate 28.

[0030] Example 2

[0031] like Figure 1-Figure 7As shown, a limiting mechanism 4 is provided inside the inclined wedge body 24, and the limiting mechanism 4 includes a hand-tightening bolt 43. A limiting groove 41 is provided on one side of the inclined wedge body 24, and a rotating plate 42 is rotatably connected inside the limiting groove 41. The hand-tightening bolts 43 are all passed through the rotating plate 42 and the inclined wedge body 24, and the hand-tightening bolts 43 are threadedly connected to the rotating plate 42 and the inclined wedge body 24. An auxiliary mechanism 5 is provided inside the oil tank 32, and the auxiliary mechanism 5 includes a fixing pipe 51, which passes through the inside of the oil tank 32 and the slide plate 31, and the outer surface of the fixing pipe 51 is connected to the inner surface of the oil tank 32. Fixed connection. There are two ways of fixed connection, bolt connection and welding. In this application document, welding is preferred. A push rod 52 runs through the interior of the fixed tube 51. The push rod 52 is slidably connected to the fixed tube 51. A handle 56 is provided at one end of the push rod 52. A plug 53 is provided at the end of the push rod 52 away from the handle 56. The plug 53 is located inside the fixed tube 51. A sealing ring 54 is connected to one side of the plug 53. The push rod 52 runs through the interior of the sealing ring 54. A limiting ring 55 is connected to the inner surface of the fixed tube 51 near one end. The push rod 52 is slidably connected to the limiting ring 55.

[0032] In this embodiment, the internal components of the protective mechanism 3 are limited by the limiting mechanism 4. When the upper driving block 23 drives the inclined wedge body 24 to perform a reciprocating motion in the vertical direction, the slide plate 31 and other protective mechanism 3 components in the slot opened on its top are prevented from falling out from the inside of the inclined wedge body 24. The limiting groove 41 opened on one side of the inclined wedge body 24 is aligned with the card slot opened on one side of the slide plate 31. Since the hand-tightening bolt 43 is threadedly connected with the rotating plate 42 and the inclined wedge body 24, the rotating plate 42 is limited by rotating the hand-tightening bolt 43, and then the sliding plate 31 is limited. The operation of the hand-tightening bolt 43 is relatively simple, which is convenient for the staff to use. The auxiliary mechanism 5 is set to help the inside of the oil tank 32 to a certain extent. A portion of the lubricating oil is transported to the inside of the connecting pipe 33, and then drips into the oil tank 38 through the distribution pipe 34 and the connecting head 35. The fixed pipe 51 is connected to the oil tank 32. A handle 56 is provided at one end of the push rod 52, and a plug 53 is provided at the other end of the push rod 52. The staff pushes the handle 56 to push the plug 53 at the other end of the push rod 52 to slide inside the fixed pipe 51. A sealing ring 54 is connected to one side of the plug 53 to prevent the lubricating oil in the oil tank 32 from flowing out to the outside through the fixed pipe 51 to a certain extent. The limit ring 55 restricts the plug 53, the sealing ring 54 and the handle 56 to prevent the internal components of the auxiliary mechanism 5 from slipping out of the fixed pipe 51 or completely sliding into the fixed pipe 51 and unable to be taken out.

[0033] Working principle:

[0034] like Figure 1-Figure 7As shown, first, the staff pulls the internal components of the protection mechanism 3 out of the interior of the inclined wedge body 24 through the pull block set on one side of the slide plate 31, rotates the tank cover 36 to pour lubricating oil into the oil tank 32, and after the oil tank 32 is filled with lubricating oil, the tank cover 36 is rotated to help the oil tank 32 seal. After the staff slides the internal components of the protection mechanism 3 into the interior of the inclined wedge body 24 through the pull block set on one side of the slide plate 31, the rotating plate 42 is rotated so that the rotating plate 42 is rotated to the limit groove 41 opened on one side of the inclined wedge body 24 and the slide plate. After the groove opened on one side of 31 is opened, the rotation plate 42 is limited by hand-tightening the bolt 43, thereby completing the limit of the rotation plate 42 on the slide plate 31. Secondly, the material is processed inside the pressing mechanism 2. The staff starts the upper driving block 23 to drive the pressing plate 22 and the inclined wedge body 24 to move downward until the bottom of the slider 25 contacts the bottom side of the groove opened on the top of the base 1. The upper driving block 23 continues to drive the inclined wedge body 24 and the pressing plate 22 to move downward. The top side slope of the connecting bevel block 26 compresses the nitrogen spring 27 therebetween, and at the same time, the slider 25 starts to slide toward one side of the unloading platform 21, and drives the stamping plate 28 to move, and cooperates with the material limiting plate 22 to stamp and bend the two ends of the material. During the pressing process, the lubricating oil stored in the oil tank 32 is transported to the connecting pipe 33 according to the gravity of the lubricating oil, and then transported to the inside of the distribution pipe 34 through the connecting pipe 33, and then transported to the inside of the distribution pipe 34 through the connecting pipe 33. The connecting head 35 drips into the oil groove 38. Since the oil groove 38 is set with a certain curvature, the lubricating oil in the oil groove 38 flows to the contact surface between the connecting bevel block 26 and the bevel wedge body 24 according to the gravity of the lubricating oil itself, thereby reducing the wear between the two. Finally, the staff pushes the handle 56 connected to one end of the push rod 52 to push the plug 53 connected to the other end of the push rod 52 to slide in the fixed tube 51, thereby to a certain extent assisting the delivery of part of the lubricating oil inside the oil tank 32 to the inside of the connecting tube 33.
