Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of pipe shrinking machines, and in particular to a shrinking tooling for a CNC shrinking machine. Background Technology
[0002] Tube reduction fittings are mainly produced using a reduction machine. The molds used for reduction fittings experience wear over time, leading to increased wear on subsequent fittings. To reduce wear, lubricating oil is applied to the reduced end of the fitting during the reduction process. Figure 5 The image shown is a physical picture of the existing pipe fittings being shrunk. The existing lubricant application is mainly done manually, with lubricant applied once each time the pipe fitting is processed using a brush. This manual application method requires workers to follow the machine's operating steps, resulting in high labor costs and is not conducive to large-scale production requirements.

[0014] A sponge is placed on the lower surface of the connecting plate, and the oil outlet pipe extends into the sponge.
[0015] Preferably, the crossbeam plate has a transverse sliding hole that penetrates the crossbeam plate, and the mounting plate is slidably connected to the side wall of the sliding hole on two opposite side walls of the mounting plate. A third locking bolt is threadedly connected to the mounting plate at the position corresponding to the crossbeam plate.
[0016] Preferably, the positioning plate is provided with a longitudinal T-shaped slide groove, a slide plate is slidably disposed in the slide groove, a crossbeam plate is provided on the slide plate, and a second locking bolt that passes through the slide plate is threadedly connected to the inner wall of the slide hole.
[0017] Preferably, the connecting plate is arc-shaped, and the sponge fills the arc groove of the connecting plate.
[0018] The beneficial effects of adopting the above technical solutions are:
[0019] This application uses a clamping plate and a first locking bolt to fix the sponge to the frame of the shrinking machine. Then, by moving the sliding plate and the mounting plate, the sponge is moved to directly above the processed pipe fitting. Then, the lifting cylinder drives the barrel cover and the oil storage tank to move downward, so that the sponge can contact the pipe fitting and add lubricating oil. At the same time, the flow valve of this application can control the amount and flow rate of lubricating oil added to the sponge from the oil storage tank. Compared with manual operation, this application is more stable and reduces labor costs. Attached Figure Description

Detailed Implementation
[0026] The embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0027] like Figure 1-4 In this first embodiment, a necking fixture for a CNC necking machine includes...
[0028] The clamping plate 20 is U-shaped, with its open end fitted onto the frame 10 of the shrinking machine. The clamping plate 20 has several first locking bolts 21.
[0029] The positioning plate 30 is longitudinally arranged on the clamping plate 20. The positioning plate 30 is provided with a longitudinal T-shaped slide groove 31. A slide plate 42 is slidably arranged in the slide groove 31. A crossbeam plate 40 is provided on the slide plate 42. The inner wall of the slide hole 41 is connected by a second locking bolt 43 that passes through the slide plate 42 through the thread.
[0030] The crossbeam plate 40 is fixedly connected to the positioning plate 30 in a longitudinally movable manner. The crossbeam plate 40 has a transverse sliding hole 41 that passes through the crossbeam plate 40. The mounting plate 50 passes through the sliding hole 41 and is slidably connected to the side wall of the sliding hole 41 on two opposite side walls. The mounting plate 50 is connected to the third locking bolt 51 by thread at the position corresponding to the crossbeam plate 40.
[0031] Mounting plate 50 is fixedly connected to crossbeam plate 40 and can move laterally;
[0032] Lifting cylinder 65 is mounted on mounting plate 50;
[0033] The threaded sleeve 64 is threadedly connected to the output end of the lifting cylinder 65 via a thread;
[0034] A bucket lid 63 is mounted on a threaded sleeve 64, and an air pipe 66 is also mounted on the bucket lid 63.
[0035] An oil storage tank 60 has an open end that is threadedly connected to a tank cover 63. The lower end wall of the oil storage tank 60 has an oil outlet pipe 61, and the oil outlet pipe 61 has a flow valve 62.
[0036] The connecting plate 71 is connected to the oil outlet pipe 61 by a thread, and the oil outlet pipe 61 passes through the connecting plate 71.
[0037] Sponge 70 is disposed on the lower surface of connecting plate 71. Oil outlet pipe 61 extends into sponge 70. Connecting plate 71 is arc-shaped, and sponge 70 fills the arc groove of connecting plate 71.
[0038] This embodiment is implemented as follows:
[0039] In use, the clamping plate 20 is first placed on the frame 10 of the shrinking machine, and then the first locking bolt 21 is rotated to tighten the frame 10 of the shrinking machine, thereby fixing the clamping plate 20. Then the sliding plate 42 and the mounting plate 50 are moved so that the sponge 70 is facing the shrinking end of the pipe fitting. Then the second locking bolt 43 is rotated to fix the sliding plate 42 on the positioning plate 30, and the third locking bolt 51 is rotated to fix the mounting plate 50 on the crossbeam plate 40.
[0040] When lubricating oil needs to be added, the lifting cylinder 65 drives the threaded sleeve 64 to move vertically, and the threaded sleeve 64 drives the barrel cover 63 and the oil storage tank 60 to move downward, so that the sponge under the connecting plate 71 can contact the constricted end of the pipe fitting, so that the lubricating oil can be applied to the outer wall of the pipe fitting, and the grease will flow downward, so that the lower surface of the pipe fitting is also covered with lubricating oil.
[0041] This application can control the flow rate of lubricating oil through the flow valve 62, thereby adjusting the amount of lubricating oil applied.
[0042] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of this utility model, and these all fall within the protection scope of this utility model.
