TECHNICAL FIELD

[0001] The present application relates to the field of metal part processing, in particular to a stamping deburring device. BACKGROUND

[0002] The castings are prone to have a ring of burrs due to the small part of the metal liquid flowing into the mold closing place, like a ring of inner wall at the hole center of some hole workpieces, which is prone to have burrs, so the burrs need to be removed after the castings are formed to improve the quality.

[0003] The existing patent No. CN211966625U discloses a blank multi-functional automatic rough machining device, the workpiece is fixed, then the main shaft capable of moving in three axes drives the cutter to rotate and enters the hole of the workpiece to remove the burrs around the hole.

[0004] According to the related technology, the cutter enters the hole center of the workpiece and then moves along the inner wall of the hole periphery to remove the burrs, which takes a long time and is difficult to quickly remove the burrs of the workpiece. SUMMARY

[0005] In order to remove the burrs of the workpiece more quickly, the present application provides a stamping deburring device.

[0006] The stamping deburring device provided by the present application adopts the following technical scheme.

[0007] A stamping deburring device comprises a pedestal, the pedestal is detachably connected with a lower die seat for positioning and placing a workpiece, the pedestal is fixedly connected with a door-shaped frame, the door-shaped frame is provided with a stamping power source, the power rod of the stamping power source is fixedly connected with a cutter head plate, the cutter head plate is detachably connected with a stamping cutter head, and the stamping cutter head can be closely inserted into the hole of the workpiece in the lower die seat.

[0008] By adopting the above technical scheme, the stamping cutter head enters the hole of the workpiece, which can directly remove the ring of burrs in the hole of the workpiece, so that the efficiency of removing the burrs of the workpiece is improved.

[0009] Optionally, the cutter head plate is fixedly connected with an elastic block on the side facing the lower die seat, the elastic block is fixedly connected with an upper die plate on the side away from the cutter head plate, the stamping power source comprises a gas-liquid booster cylinder.

[0010] By adopting the technical scheme, the stamping power source first drives the stamping cutter head to move quickly to approach the workpiece by using air pressure, and then drives the stamping cutter head to slowly insert into the workpiece hole by using oil pressure, so that the workpiece is not easily impacted, and when the stamping cutter head needs to be moved out after being closely inserted into the workpiece hole, the elastic block forces the upper die plate to always closely adhere to the workpiece, so that the workpiece is not easily moved upward with the upward movement of the stamping cutter head.

[0011] Optionally, the base is provided with a base opening opposite to the lower die base, the lower die base is provided with a lower die base opening aligned with the base opening and the workpiece hole, the base is provided with a vacuum pump for forming negative pressure in the base opening to suck the burrs fallen from the inner wall of the workpiece hole, the base is formed with a collection chamber communicated with the base opening and the air inlet of the vacuum pump, and the base is detachably connected with a chamber door capable of cleaning the collected burrs from the collection chamber.

[0012] By adopting the technical scheme, the fallen burrs can be sucked into the collection chamber through the lower die base opening and the base opening, so as to centrally process the burrs removed from the workpiece.

[0014] By adopting the technical scheme, the burrs can be collected at the chamber door, so that the internal space of the collection chamber is small, the burrs in the collection chamber can be taken out for processing without the worker's hand being inserted, and the small space of the collection chamber makes the negative pressure formed at the lower die base opening larger, so that some small burrs are not easily accumulated at the periphery of the lower die base opening when the stamping cutter head presses the burrs from the workpiece, and in addition, the height of the end of the collection chamber communicated with the vacuum pump is set, so that the burrs are not easily sucked into the vacuum pump.

[0015] Optionally, two blocking plates are slidably connected to the opening of the base opening close to the lower die base, and the base is provided with a plate moving mechanism capable of driving the two blocking plates to approach each other to close the base opening.

[0016] By adopting the technical scheme, when the deburring work is not performed, the two blocking plates block the base opening, so that some sundries are not easily inserted into the collection chamber.

[0019] Optionally, the door-shaped frame is slidably connected with a contact block capable of moving along with the movement of the upper die plate, and the door-shaped frame is fixedly connected with a micro switch capable of operating the vacuum pump when the contact block abuts against the micro switch.

[0020] By adopting the technical scheme, the contact block contacts the micro switch only when the stamping tool head moves downwards to deburr, at this time, the vacuum pump starts to work, so that the vacuum pump does not continuously work when there is no deburring, and energy consumption is reduced.

[0021] Optionally, the horizontal moving inclined wedge is fixedly connected with a passive inclined wedge, and the contact block is fixedly connected with a reverse inclined wedge capable of being pushed by the passive inclined wedge to move towards the micro switch, and the micro switch is located on the side of the door-shaped frame away from the base seat.

[0022] By adopting the technical scheme, the contact block can move synchronously along with the movement of the upper die plate, and the micro switch has a certain height, so that the micro switch is not easy to be mistakenly touched by external sundries in the machining workshop, and the vacuum pump is not easy to work randomly when there is no deburring.

[0023] Optionally, the stamping tool head comprises a sleeve block connected to a tool head plate, a plug block inserted into the sleeve block and a workpiece hole, a port member arranged at an opening of the sleeve block, an inner member arranged at the plug block and capable of abutting against the port member, and an inner spring arranged in the sleeve block and forcing the plug block to move away from the sleeve block.

[0025] Optionally, the plug block is formed with a breaking block at an end away from the sleeve block, and the area of the breaking block away from the plug block side is smaller.

[0026] By adopting the technical scheme, the breaking block first contacts the side of the burr away from the inner wall of the workpiece hole, so that when a large burr is encountered, the breaking block can first press the large burr away from the inner wall of the workpiece hole and break it, so as to divide the large burr into smaller burrs, so as to concentrate the burrs in the collecting chamber.

[0027] In summary, the present application includes at least one of the following beneficial effects:

[0028] 1. Punch head into the workpiece hole, can directly remove a circle of burr in the workpiece hole, so that the efficiency of workpiece deburring is improved;

[0036] The present application will be further described in detail below in combination with the drawings.

[0037] The embodiment of the present application discloses a punch deburring device, referring to Figure 1, including the pedestal 1 placed on the ground, the upper surface of the pedestal 1 is detachably connected with the horizontal lower die seat 2 through bolts, the lower die seat 2 is used for placing the workpiece which needs to be deburred in a fixed posture, the upper surface of the pedestal 1 is fixedly connected with the vertical door-shaped frame 3, the upper surface of the door-shaped frame 3 is fixedly connected with the stamping power source 4, the stamping power source 4 can be a gas-liquid pressure cylinder, the vertical power rod bottom end of the stamping power source 4 is fixedly connected with the horizontal cutter head plate 51, the lower surface of the cutter head plate 51 is detachably connected with the stamping cutter head 5 through bolts, the stamping cutter head 5 is tightly inserted into the inner wall of the workpiece hole in the vertical direction, so as to remove a circle of burrs in the workpiece hole.

[0038] With reference to Figure 1 and Figure 2 , a plurality of elastic blocks 52 are fixedly connected at the bottom periphery of the cutter head plate 51, the elastic blocks 52 can be cow leather materials made of TPE or TPR, the bottom surface of the elastic block 52 is fixedly connected with the upper die plate 53, the center of the upper die plate 53 is provided with an opening for the stamping cutter head 5 to pass through, the stamping power source 4 quickly drives the stamping cutter head 5 to approach the workpiece with the gas source as the power, until the upper die plate 53 abuts against the upper surface of the workpiece, at this time, the stamping power source 4 drives the stamping cutter head 5 to slowly move downward with the oil source, so that the elastic blocks 52 are compressed, that is, the deburring work can be carried out relatively quickly, and the stamping cutter head 5 enters the workpiece hole at a relatively slow speed, so that the workpiece is not easily subjected to a relatively large impact force. When the stamping cutter head 5 completely enters the workpiece hole to complete the deburring, the stamping cutter head 5 moves upward, at this time, the elastic blocks 52 restore the shape, so that the workpiece is not easily moved upward with the upward movement of the stamping cutter head 5, so that the workpiece and the stamping cutter head 5 are smoothly separated.

[0039] With reference to Figure 2 and Figure 3 , the stamping cutter head 5 comprises a sleeve block 32 detachably connected to the cutter head plate 51, the sleeve block 32 is sleeved with an insertion block 33 in the vertical direction, the insertion block 33 is inserted into the workpiece hole at one end of the sleeve block 32, the insertion block 33 is fixedly connected with an inner part 35 at one end inside the sleeve block 32, the inner part 35 is slidingly connected to the inner wall of the sleeve block 32 in the vertical direction, the sleeve block 32 is detachably connected with a port part 34 at the bottom end face, the upper surface of the port part 34 abuts against the lower surface of the inner part 35, so that the insertion block 33 is not easily separated from the inside of the sleeve block 32. The sleeve block 32 is put into an inner spring 36 which forces the insertion block 33 to move downward, so that the pressure applied to the burr by the insertion block 33 is slowly increased, so as to reduce the damage to the inner wall of the workpiece hole as much as possible when deburring. The insertion block 33 is integrally formed with a crushing block 37 at the bottom end, the crushing block 37 is in the shape of a prism, the bottom surface area of the crushing block 37 is smaller than the top surface area of the crushing block 37, so that the bottom of the crushing block 37 can be close to the side of the burr away from the inner wall of the workpiece hole, so that the burr with a larger volume can be crushed by the crushing block 37 first, so that the burr is more easily collected subsequently.

[0040] With reference to Figure 1 andFigure 2 The lower die base 2 is provided with a lower die base opening 55 penetrating the hole of the workpiece, the pedestal 1 is provided with a pedestal opening 54 penetrating the lower die base opening 55, the pedestal opening 54 is vertical, the pedestal 1 is provided with a collection chamber 57 penetrating the vertical side of the pedestal 1, the collection chamber 57 is inclined, and the inclined bottom of the collection chamber 57 penetrates the vertical side of the pedestal 1, and the vertical side of the pedestal 1 penetrated by the collection chamber 57 is detachably connected with a chamber door 58 blocking the bottom opening of the collection chamber 57. The internal space of the collection chamber 57 is small, and the inclined upper surface of the collection chamber 57 is connected with a vacuum pump 56, and the position of the vacuum pump 56 connected with the collection chamber 57 is higher than the opening height of the pedestal opening 54 connected with the collection chamber 57, so that the burrs are more difficult to accumulate in the vacuum pump 56 while being sucked into the collection chamber 57.
