[0008] Furthermore, the side surface of the sealing slide plate is always in contact with the surface of the air cavity; a plurality of exhaust holes are distributed circumferentially on the side surface of the punch head, and the exhaust holes are located above the polishing sleeve as a whole; each of the exhaust holes is connected to the top of the air cavity.
[0009] Furthermore, the lower die base is provided with a plurality of annular liquid cavities which are concentric with the through hole but have different diameters; the plurality of liquid cavities are interconnected; and a circulation component for driving the flow of liquid in the liquid cavity is installed in the cavity.
[0010] Furthermore, the lower die base is also formed with inclined holes corresponding to the number of liquid cavities; one end of the inclined hole is connected to the liquid cavity, and the other end extends toward the driving rod and communicates with the interior of the cavity.
[0011] Furthermore, the circulating part includes an eccentric wheel, a piston tube, a piston rod and a return spring; the eccentric wheel is sleeved on the top of the driving rod; the piston tube is transversely fixedly installed in the cavity; a piston rod is installed in the piston tube, and the piston rod has a piston part and a rod part, and the rod part passes through one end of the piston tube and contacts the side of the eccentric wheel; the return spring is installed in the piston tube, and the return spring is located on the side of the piston part away from the rod part; the two ends of the piston tube are respectively connected with a one-way liquid inlet valve tube and a one-way liquid outlet valve tube; wherein, the other end of the one-way liquid inlet valve tube is located in the cavity injected with cooling water, and the other end of the one-way liquid outlet valve tube is connected with the liquid cavity.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0035] Please refer to Figure 1 As shown, the present invention provides a stamping synchronous deburring device, comprising an upper die base 1, a punch head 101 vertically installed on the upper die base 1, and the punch head 101 is cylindrical; and a lower die base 102, and a through hole 103 penetrating the lower die base 102, and the through hole 103 is a circular hole; as mentioned above, the operator can place the sheet workpiece on the lower die base 102 in advance, and position the sheet workpiece through an external clamp (not shown in the figure), and then control the upper die base 1 and the punch head 101 to perform vertical lifting and lowering movements through the action of an external hydraulic rod, and achieve punching of the metal sheet workpiece on the lower die base 102 with the help of the cooperation between the punch head 101 and the through hole 103. The above is the existing public known technology and will not be repeated.
[0036] The difference is that the present application also includes a grinding sleeve 2, which is sleeved on the outside of the punch head 101, the grinding sleeve 2 has the same diameter as the punch head 101, and the grinding particles on the grinding surface of the grinding sleeve 2 are slightly convex, which is convenient for subsequent grinding of the cut surface of the plate workpiece; furthermore, the punch head 101 is also rotatably connected to the upper die seat 1; wherein, after the punch head 101 is inserted into the through hole 103 (that is, after completing the punching and punching processing of the plate workpiece), it can drive the grinding sleeve 2 to rotate around its own axis;
[0037] During operation: after the punching head 101 moves downward to punch a hole in the sheet workpiece, the grinding sleeve 2 can continuously move downward with the punching head 101, and the grinding surface of the grinding sleeve 2 can continuously contact and grind the cut surface of the sheet workpiece to reduce burrs; at the same time, the punching head 101 can rotate during its continuous downward movement, and the grinding sleeve 2 moves downward and rotates at the same time to make the cut surface of the sheet workpiece smooth, thereby achieving synchronous deburring during stamping and ensuring the processing quality of the sheet workpiece.
[0038] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, an air cavity 201 is provided inside the punch head 101; a sealing slide plate 202 is slidably connected inside the air cavity 201; a sliding rod 203 slidably connected to the punch head 101 is installed at one end of the sealing slide plate 202 facing the lower die base 102; a connecting spring 204 is sleeved on the outside of the sliding rod 203, and the connecting spring 204 is used to connect the sealing slide plate 202 and the punch head 101; that is, in the initial state, the connecting spring 204 causes the lower part of the sliding rod 203 to extend out of the air cavity 201 and be located below the punch head 101, and during the process in which the bottom end of the sliding rod 203 is in continuous contact with the sheet workpiece, the sliding rod 20 3 will be squeezed into the punch head 101 by the sheet workpiece, and move to the maximum stroke on the sealing slide 202 (the sealing slide 202 contacts the top surface of the air cavity 201). At this time, the slide bar 203 is completely retracted into the air cavity 201, and the bottom end surface of the slide bar 203 will be flush with the bottom end surface of the punch head 101, so that the bottom end surface of the punch head 101 forms a flat punching contact surface, and the matching clearance between the slide bar 203 and the punch head 101 can be ignored; it is worth noting that a connecting hole connected to the side of the punch head 101 is opened at the bottom of the air cavity 201 (shown in the figure, but not numbered, can be as shown Figure 3 As shown), to ensure that the sealing slide plate 202 can slide in the air cavity 201; a cavity is formed in the lower die base 102, and a rotatable driving rod 205 is rotatably installed in the cavity. The driving rod 205 is arranged vertically as a whole, and its axis is on the same vertical center line as the through hole 103. The top of the driving rod 205 is formed with a socket 206 for the sliding rod 203 to be vertically inserted;
[0039] During operation: after the punch head 101 contacts the sheet workpiece, the slide bar 203 will be completely retracted into the air cavity 201; after the punch head 101 continues to move downward and completes punching the sheet workpiece, the connecting spring 204 stretches the sealing slide plate 202 and the slide bar 203 moves downward quickly, so that the punched waste is first pushed into the cavity for storage through the slide bar 203, and then the slide bar 203 is inserted into the socket 206 set on the drive rod 205 during the continuous downward movement process, and the rotating drive rod 205 drives the slide bar 203, the punch head 101, and the grinding sleeve 2 to rotate synchronously, so as to realize the rotational grinding of the cut surface by the grinding sleeve 2; the difference is that during punching, the punch head 101 does not rotate, and only after the punching is completed, the slide bar 203 and the drive rod 205 form an opportunity for cooperation, so that the punch head 101 can form the ability of rotational grinding;
[0040] The driving rod 205 is fixed in position (just rotating), and the punch head 101 continuously moves downward, so that during the contact and extrusion process between the slide bar 203 and the driving rod 205, the slide bar 203 moves upward in the air cavity 201 and forms an adaptive adjustment of the position, thereby realizing the downward movement and rotation of the grinding sleeve 2, so that the relatively clean grinding surfaces of the grinding sleeve 2 at different positions can all contact and grind with the cut surface (hole) of the plate workpiece, thereby improving the grinding effect;
[0041] At the same time, the downward movement and rotation action of the grinding sleeve 2 can bring the waste polished out of the holes of the plate workpiece to the internal cavity of the lower die seat 102 for temporary storage; compared with the prior art in which the grinding piece only performs circumferential rotation grinding, burrs and other waste materials will always be stuck between the grinding piece and the hole. As the grinding piece rotates, the waste materials continue to contact and scratch the smooth surface in the hole, which leads to the uneven surface of the hole of the workpiece after stamping; and the downward movement and rotation action of the grinding sleeve 2 in the present application can solve this problem, improve the grinding quality, reduce the dust and waste materials from spreading into the processing environment during the grinding process, and optimize the processing environment.
[0042] Reference Figure 3 and Figure 6 As shown, the side of the sealing slide plate 202 is always in contact with the surface of the air cavity 201; a plurality of exhaust holes 207 are distributed circumferentially on the side of the punch head 101, and the exhaust holes 207 are located above the polishing sleeve 2; each exhaust hole 207 is connected to the top of the air cavity 201;
[0043] During work: After the metal sheet workpiece is stamped, the energy conversion inside the metal at the cut surface will generate heat, causing the temperature at the cut surface to rise. Especially for soft metal materials, if not cooled in time, it may cause subsequent deformation;
[0044] To this end, on the basis that the slide bar 203 enters the socket 206 and contacts and squeezes the drive rod 205, the continuous downward movement of the punch head 101 can make the slide bar 203 and the sealing slide plate 202 slide upward in the air cavity 201. Since the side surface of the sealing slide plate 202 is always in contact with the surface of the air cavity 201, the gas previously drawn into the air cavity 201 is gradually squeezed out (the sealing slide plate 202 slides downward to draw external gas into the air cavity 201 from the exhaust hole 207), and the squeezed gas is continuously ejected from the exhaust hole 207; on the one hand, as the punch head 101 continues to move downward, the continuous exhaust of the exhaust hole 207 acts on the top surface of the sheet workpiece (mainly reflected in the surface near the hole), thereby achieving the sheet workpiece Heat dissipation and cooling of the metal surface near the hole; on the other hand, as the punch head 101 continues to move downward, the outlet of the exhaust hole 207 will be located in the hole of the plate workpiece (at the cut surface). The temperature of this hole is relatively the highest due to the action of the punching and grinding sleeve 2. At this time, the exhaust hole 207 continues to discharge gas and can directly act on the cut surface, so the heat dissipation effect is good; at the same time, when the exhaust hole 207 is located in the hole, the gas discharged from the exhaust hole 207 can only be forcibly discharged upward and downward from the gap between the hole and the grinding sleeve 2 / punching head 101, so that the gas can contact all surfaces of the hole during the flow process, further improving the heat dissipation of the hole after stamping and grinding, reducing the possibility of subsequent workpiece deformation, and improving the quality of the workpiece.
[0045] Reference Figure 4 and Figure 7 As shown, the lower die base 102 is provided with a plurality of annular liquid cavities 3 which are concentric with the through hole 103 and have different diameters; the plurality of liquid cavities 3 are interconnected; and a circulation member 302 for driving the liquid in the liquid cavity 3 to flow is installed in the cavity;
[0046] During operation: the liquid cavity 3 is distributed near the hole of the workpiece. When the heat of the workpiece is transferred to the lower die seat 102, the cooling water in the liquid cavity 3 can take away the heat generated by the stamping of the workpiece and the grinding in the hole (mainly the bottom end surface of the workpiece, which dissipates heat together with the above-mentioned top end surface, just forming a double-sided heat dissipation of the sheet workpiece), forming a timely exchange of heat, and with the use of the circulation part 302, it is ensured that the cooling water after heat exchange in the liquid cavity 3 can be circulated and discharged, thereby improving the forming quality of the workpiece.
[0047] Reference Figure 4 , Figure 7 and Figure 8 As shown, the lower die base 102 is also formed with inclined holes 301 corresponding to the number of liquid cavities 3; one end of the inclined hole 301 is connected to the liquid cavity 3, and the other end extends toward the driving rod 205 and communicates with the interior of the cavity;
[0048] During operation: the circulation member 302 can circulate the cooling water in the liquid chamber 3 and continuously discharge it from the inclined hole 301. After the punch head 101 and the grinding sleeve 2 extend into the through hole 103, the cooling water discharged from the inclined hole 301 can be sprayed onto the surface of the punch head 101 and the grinding sleeve 2.
[0049] On the one hand, the sprayed cooling water liquid can cool the punch head 101 and the grinding sleeve 2; this action is because the punch head 101 needs to perform continuous punching operations, and the continuous operation temperature rise will cause wear and passivation of the punch head 101 or the cutting edge; therefore, the contact between the cooling water and the punch head 101 can reduce the temperature of the punch head 101, ensure the ability of the punch head 101 to operate continuously, and extend the service life of the punch head 101;
[0050] On the other hand, the contact between the sprayed cooling water liquid and the grinding sleeve 2 can also form a cooling of the surface of the grinding sleeve 2, thereby improving the grinding accuracy and quality of the next grinding sleeve 2. At the same time, the cooling water can also rinse the grinding surface of the grinding sleeve 2, thereby ensuring the cleanliness of the grinding surface and improving the grinding accuracy and quality.
[0051] It is worth noting that Figure 8 As shown, the punch head 101 and the grinding sleeve 2 extending into the lower die seat 102 form a circumferential rotation action. Through this action feature, all surfaces of the grinding sleeve 2 can contact with the cooling water liquid sprayed from the inclined hole 301, thereby further improving the cooling and cleaning quality of the grinding surface of the grinding sleeve 2.
[0052] Reference Figure 8 and Figure 4As shown, the circulation member 302 includes an eccentric wheel 302a, a piston tube 302b, a piston rod 302c and a return spring 302d; the eccentric wheel 302a is sleeved on the top of the driving rod 205; the piston tube 302b is transversely fixedly installed in the cavity; a piston rod 302c is installed in the piston tube 302b, and the piston rod 302c has a piston part and a rod part (which is a well-known technology and will not be described in detail), and the rod part passes through one end of the piston tube 302b and then contacts the side of the eccentric wheel 302a; the return spring 302d is installed in the piston tube 302b, and the return spring 302d is located on the side of the piston part away from the rod part; the two ends of the piston tube 302b are respectively connected with a one-way liquid inlet valve tube and a one-way liquid outlet valve tube (shown in the figure, but not numbered); wherein, the other end (inlet) of the one-way liquid inlet valve tube is located in the volume chamber injected with cooling water and is located below the liquid surface, and a filter head is provided at the pipe mouth located below the liquid surface to ensure that the cooling water liquid drawn into the one-way liquid inlet valve tube is relatively clean; the other end of the one-way liquid outlet valve tube is connected with the liquid chamber 3 away from the inclined hole 301;
[0053] It is worth noting that, when processing workpieces with larger specifications, the present application can also add refrigeration equipment to cool the cooling water in the cavity to ensure the temperature of the cooling water;
[0054] During operation: on the basis of the rotation of the driving rod 205, it can drive the eccentric wheel 302a to rotate synchronously, and through the setting of the return spring 302d, the eccentric wheel 302a can repeatedly squeeze the piston rod 302c to move back and forth horizontally in the piston tube 302b, so that the cooling water in the cavity is drawn into the piston tube 302b through the one-way liquid inlet valve tube, and the cooling water in the piston tube 302b is squeezed into the liquid cavity 3 through the one-way liquid outlet valve tube, and the cooling water in the liquid cavity 3 is sprayed out from the inclined hole 301 and falls into the liquid cavity 3, thereby forming a cooling water circulation in the liquid cavity 3;
[0055] The difference is that the piston part divides the piston tube 302b into two water storage chambers, and the movement of the piston rod 302c can realize the cooling water in the two water storage chambers to be alternately injected into the liquid chamber 3, thereby realizing uninterrupted circulation of the cooling water in the liquid chamber 3, ensuring that the cooling water in the liquid chamber 3 continuously cools the sheet workpiece, and the inclined hole 301 continuously discharges water to cool and flush the punch head 101 and the grinding sleeve 2.
[0056] Reference Figure 2 As shown, a filter plate 4 is also slidably connected in the cavity; a support spring 401 is also installed in the cavity, and the other end of the support spring 401 is connected to the bottom end of the filter plate 4; the filter plate 4 is arranged in an inclined manner as a whole; the side surface of the filter plate 4 is in contact with the surface of the cavity;
[0057] During operation: the setting of the filter plate 4 can intercept the waste material that is flushed out of the plate workpiece and falls, and prevent the waste material from falling into the bottom of the cavity and mixing with the cooling water; obviously the flushed waste material also has a certain amount of heat, and separating the waste material from the cooling water through the filter plate 4 can reduce the temperature of the circulating cooling water; furthermore, the filter plate 4 is tilted, and the waste material thereon will gather to a lower place by gravity, which is convenient for subsequent waste collection on the one hand; on the other hand, it prevents the waste material from gathering in the middle of the filter plate 4, reduces the possibility of contact and heat exchange between the cooling water sprayed from the inclined hole 301 and the accumulated waste material on the filter plate 4, and improves the effect of subsequent circulating cooling of the cooling water.
[0058] Reference Figure 2 As shown, a discharge port 402 is also provided on the lower die base 102; the discharge port 402 is located on a relatively lower side of the filter plate 4 as a whole;
[0059] During operation: when the waste accumulated on the filter plate 4 gathers toward the lower part, it will be discharged through the discharge device located at the lower part of the filter plate 4, so as to realize the discharge and collection of the waste.
[0060] Reference Figure 2 and Figure 8 As shown, a squeeze rod 403 is also vertically installed at the bottom end of the eccentric wheel 302a; a ball is rotatably arranged at one end of the squeeze rod 403 that contacts the filter plate 4, so as to reduce the contact wear between the squeeze rod 403 and the filter plate 4;
[0061] During operation: on the basis of the rotation of the driving rod 205 and the eccentric wheel 302a, the squeezing rod 403 can be driven to rotate synchronously. Since the filter plate 4 is tilted as a whole, during the rotation of the squeezing rod 403, the bottom end of the squeezing rod 403 contacts and squeezes the filter plate 4, which can force the filter plate 4 to move downward. The filter plate 4 is also supported by the support spring 401. Therefore, the change of the contact position between the squeezing rod 403 and the filter plate 4 can be used in conjunction with the support spring 401 to achieve the up and down vibration of the filter plate 4.
[0062] The efficiency of unloading waste from the filter plate 4 is accelerated by shaking up and down. At the same time, the shaking up and down of the filter plate 4 also accelerates the flow of surrounding air, ensuring that cooling water with a certain amount of heat can be cooled, further improving the effect of subsequent circulating cooling of the cooling water.
[0063] Reference Figure 2 and Figure 8 As shown, in order to realize the rotation of the driving rod 205, a motor (shown in the figure but not numbered) is also installed at the bottom end of the lower mold base 102, and the output end of the motor is fixedly connected to the driving rod 205, and the driving rod 205 is driven to rotate by the action of the motor.

Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
