[0002] The domestic magnetic material processing industry has been developing at an increasingly faster pace since the 1990s, and various equipment dedicated to the processing of the above materials has also been continuously improved and innovated.

[0003] The magnetic material workpiece needs to be processed by a trepanning cutter when trepanning, and cooling oil needs to be sprayed to cool the processed surface during processing. The prior art also needs to eject the material coming out of the trepanning after processing. The prior art generally sets a push rod and a cylinder, and the push rod is driven by the cylinder to eject the material coming out of the trepanning in the middle of the workpiece, so the overall structure is relatively complicated. Utility Model Content

It also includes an oil storage cylinder body fixed on the slide and having an oil storage chamber inside, a piston slidably connected in the oil storage chamber for squeezing out cooling oil stored in the oil storage chamber, and a cylinder for driving the piston to move, the oil inlet pipe includes a first oil inlet pipe and a second oil inlet pipe, the first oil inlet pipe connects one end of the oil inlet hole with the oil storage chamber, and the second oil inlet pipe connects the oil storage chamber with the oil inlet device.

[0006] Preferably, the chuck, the oil inlet seat and the first oil inlet pipe are multiple, and the multiple first oil inlet pipes are connected to the oil storage chamber through a multi-way connector.

[0007] Preferably, locking holes for locking members to pass through and lock are respectively provided on the left and right sides of the multi-way connector.

[0008] Preferably, the inlet of the piston is arranged at one end of the oil storage chamber, and the first oil inlet pipe and the second oil inlet pipe are connected to the other end of the oil storage chamber.

[0009] Preferably, the oil storage chamber is provided with a first connecting port for connecting to the first oil inlet pipe and a second connecting port for connecting to the second oil inlet pipe, and the first connecting port is arranged opposite to the second connecting port.

[0010] Compared with the prior art, the utility model adopts the above structure and has the following advantages: an oil storage cylinder body, a piston and a cylinder are provided, so that when the core is not needed, the piston is in the initial state, and the operation of the cooling oil is still the same as the prior art, flowing out from the cutting hole of the piercing cutter to cool the processed workpiece, and when the core is needed, the piston is controlled to push forward to push out the oil in the oil storage chamber, and the pressure in the first oil inlet pipe will become much larger at this time, which will cause the cooling oil flowing out of the cutting hole of the piercing cutter to have a fast flow rate and a large impact force, so that the material coming out of the piercing hole in the middle of the workpiece can be pushed out, so there is no need to use a push rod to push out the material coming out of the piercing hole in the middle of the workpiece, the overall structure is simple, and will not cause damage to the workpiece, and the reliability is also high.

[0011] A plurality of chucks, oil inlet seats and first oil inlet pipes are provided, so that a plurality of workpieces can be processed together, the processing efficiency is high, and only one oil storage cylinder body and piston are needed to realize the core pushing action on a plurality of workpieces.

[0012] Locking holes are respectively arranged on both sides of the multi-way connector, so that the multi-way connector can be well fixed and stabilized.

[0013] In this way, when the piston moves to the bottom, most of the cooling oil in the oil storage chamber can be squeezed out, which can achieve a better core pushing effect.

[0014] The first connection port and the second connection port are arranged opposite to each other, so that the cooling oil flowing into the first connection port can directly flow out from the second connection port under normal conditions. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0019] Embodiment 1:

[0020] A tool sleeve and core pushing device for a fully automatic sleeve and punching machine comprises a slide 1, a tool holder 2, a chuck 3, an oil feeding mechanism and a core pushing mechanism, wherein:

[0021] The slide 1 is fixed on the workbench and can slide on the workbench through the guide rail;

[0022] The tool holder 2 is fixed on one side of the slide 1 and is used to fix the chuck 3 and then the trepanning cutter 6;

[0023] A chuck 3 is fixed on the tool holder 2 and is used for clamping the hole cutter 6;

[0024] The oil inlet mechanism is used to provide cooling oil to the workpiece being processed, and includes an oil inlet seat 4, an oil inlet connecting sleeve, a first oil inlet pipe 11, an oil inlet nozzle and an oil inlet device 5.

[0025] The oil inlet seat 4 is fixed on the slide 1 and is provided with an oil inlet hole;

[0026] The oil inlet connecting sleeve is arranged in the oil inlet hole of the oil inlet seat 4, and an oil inlet passage is arranged therein. One end of the oil inlet connecting sleeve is connected to one end of the first oil inlet pipe 11, and the other end of the oil inlet connecting sleeve is connected to the oil inlet nozzle;

[0027] The oil inlet nozzle is connected to the chuck 3, so that when the trepanning cutter 6 is installed on the chuck 3, the cooling oil flowing out of the oil inlet nozzle will flow into the cutting hole in the middle of the trepanning cutter 6;

[0028] There are three oil inlet mechanisms and three chucks 3;

[0029] The core-pushing mechanism includes an oil storage cylinder body 8, a piston 9, a cylinder 10, a multi-way connector 13 and a second oil inlet pipe 12, wherein:

[0030] The oil storage cylinder 8 has an oil storage chamber 7 disposed therein, and a first connection port 15 and a second connection port 16 are disposed on both sides thereof, and both the first connection port 15 and the second connection port 16 are communicated with the oil storage chamber 7;

[0031] The piston 9 is slidably connected in the oil storage chamber 7, and can squeeze out the cooling oil in the oil storage chamber 7 when sliding;

[0032] The cylinder 10 is used to drive the piston 9 to slide in the oil storage chamber 7;

[0033] One end of the multi-way connector 13 is connected to the first connection port 15, and the other end of the multi-way connector 13 is connected to the plurality of first oil inlet pipes 11, and locking holes 14 are provided at both ends thereof, and the multi-way connector 13 is fixed on the slide 1 by passing the locking member through the locking holes 14;

[0034] The oil inlet device 5 is connected to the second connecting port 16 through the second oil inlet pipe 12;

[0035] The working principle of this embodiment is: when the workpiece does not need to be pushed, the piston 9 is close to the cylinder 10, and the space of the oil storage chamber 7 is the largest. The cooling oil enters the cutting hole of the piercing cutter 6 through the oil inlet device 5, the second oil inlet pipe 12, the oil storage chamber 7, the first oil inlet pipe 11, the oil inlet connecting sleeve and the oil inlet nozzle to cool the processed workpiece. When the core is needed, the cylinder 10 drives the piston 9 to squeeze out the cooling oil in the oil storage chamber 7. At this time, the pressure in the first oil inlet pipe 11 will become much larger, which will make the cooling oil flowing out of the cutting hole of the piercing cutter 6 very fast, that is, the cooling oil will spray out and then hit the middle part of the workpiece, and then the middle material that has been cut will be pushed out to achieve the core.

[0036] Embodiment 2:

[0037] The difference from the first embodiment is that in the second embodiment, the inlet of the piston 9 is arranged at one end of the oil storage chamber 7, the first connecting port 15 and the second connecting port 16 are connected to the other end of the oil storage chamber 7, and the first connecting port 15 and the second connecting port 16 are arranged opposite to each other, so that when the core is not needed, the cooling oil can directly flow in from the second connecting port 16 and then flow out from the first connecting port 15, which will not affect the normal cooling oil supply, and when the core is needed, this arrangement can squeeze out most of the cooling oil in the oil storage chamber 7, and the core pushing effect is better.

[0038] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.

[0039] For those skilled in the art, various changes and modifications will undoubtedly be obvious after reading the above description. Therefore, the attached claims should be regarded as covering all changes and modifications to the true intent and scope of the utility model. Any and all equivalent ranges and contents within the scope of the claims should be considered to still be within the intent and scope of the utility model.
