DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0025] Example 1

[0026] The present invention provides a stamping die for automatic production of universal metal accessories for furniture products, such as Figures 1 to 5 As shown, it includes: a bottom plate 1, four limiting columns 2 are installed on the top of the bottom plate 1, a lifting plate 3 is installed between the outer sides of the two limiting columns 2, and the number of lifting plates 3 is set to two. A clamping plate 4 is installed on the top of the two lifting plates 3. A hydraulic rod is clamped and installed inside the clamping plate 4. The hydraulic rod is used for lifting objects. A plurality of top plates 1 5 are installed on the bottom end of one of the lifting plates 3, and a plurality of top plates 2 6 are installed on the bottom end of the other lifting plate 3. A lower mold 7 is installed at the bottom end of the top plate 1 corresponding to the top plate 1 5 and the top plate 2 6. Four guide columns 9 are installed at the bottom of top plate 15 and top plate 26, and a pressure block 10 is slidably connected to the outer side of the guide column 9. Four positioning pins 11 are fixedly installed at the bottom of the pressure block 10. Four return springs 12 are fixedly installed between the top of the pressure block 10 and the bottom end of top plate 15. The return spring 12 is sleeved on the outer side of the guide column 9. A punching rod 8 is fixedly installed inside top plate 15 and top plate 26. A cylinder 13 is symmetrically installed at the top of the bottom plate 1 at one end of the lower mold 7, and a clamping plate 14 is fixedly connected between the output shafts of the two cylinders 13.

[0027] like Figure 1 and Figure 3 As shown, the clamping plate 14 is L-shaped and has a slot corresponding to the lower mold 7 opened inside. The two clamping plates 14 are combined into a rectangle, and a limit block 15 is fixedly installed on the outer side of the top clamping plate 14;

[0028] The limiting block 15 prevents the two clamping plates 14 from being misaligned, and the cylinder 13 drives the two clamping plates 14 to move relative to each other, thereby pre-limiting the raw materials.

[0029] like Figure 1 and Figure 3 As shown, the ratio of the number of the lower mold 7, the guide column 9, the pressure block 10, the positioning pin 11 and the return spring 12 is 1:4:1:4:4, and the number of the lower molds 7 is set to six in total, of which the holes inside three lower molds 7 are the same, and the holes inside the other three lower molds 7 are the same, among which the holes inside three lower molds 7 are different from the holes inside the other three lower molds 7, and the holes inside the three lower molds 7 located at the bottom end of the top plate 2 6 are the same;

[0030] Through two different holes, the product can be punched with two different holes at the same time, which improves the punching efficiency. Under the action of three groups, three groups of materials can be processed at the same time, which improves the processing efficiency.

[0031] like Figure 2 , Figure 4 and Figure 5As shown, a grinding adsorption assembly 16 is installed in the middle of the bottom plate 1, and the grinding adsorption assembly 16 includes a connecting sleeve 1604 symmetrically installed in the middle of the top of the bottom plate 1, and a lifting rod 1605 is movably connected inside the connecting sleeve 1604, and a synchronous plate 1618 is fixedly installed on the top of the lifting rod 1605, and a rotating cover 1606 is rotatably connected inside the synchronous plate 1618, and a grinding sheet 1607 is fixedly installed on the top of the rotating cover 1606, and a fan blade 1613 is rotatably connected inside the rotating cover 1606;

[0032] Through the rotation of the fan blades 1613, the grinding sheet 1607 can absorb the waste chips generated in the metal grinding process, and the rotating cover 1606 can be raised and lowered under the action of the synchronous plate 1618. When the rotating cover 1606 is raised and lowered, it drives the grinding sheet 1607 to be raised and lowered. When the grinding sheet 1607 is raised and lowered, it comes into contact with or separates from the object to be polished, thereby changing the difficulty of the grinding sheet 1607 coming into contact with or separating from the object to be polished.

[0033] like Figure 4 and Figure 5 As shown, a connecting tube 1603 is embedded in the connecting sleeve 1604, one end of the connecting tube 1603 is sleeved with a piston sleeve 1601, a piston rod 1602 is vertically slidably connected inside the piston sleeve 1601, the piston rod 1602 is fixedly installed on one end surface of the pressing block 10, the top end of the piston rod 1602 and the bottom end of the synchronous plate 1618 are fixedly connected, and the number ratio of the piston rod 1602 to the synchronous plate 1618 is one to two;

[0034] When the piston rod 1602 presses the inside of the piston sleeve 1601, the gas enters the connecting sleeve 1604 along the connecting pipe 1603, and drives the lifting rod 1605 inside the connecting sleeve 1604 to rise and fall, thereby changing the difficulty of lifting the lifting rod 1605.

[0035] like Figure 4 and Figure 5 As shown, a clamping ring 1608 is clamped and installed inside the rotating cover 1606, a filter cloth 1609 is fixedly installed at the bottom end of the clamping ring 1608, and a guide groove is opened inside the rotating cover 1606 at the top position of the clamping ring 1608;

[0036] Since the fan blades 1613 rotate at a high speed, the dirt generated during grinding is adsorbed, and the adsorbed dirt enters the outside of the filter cloth 1609 and is filtered through the filter cloth 1609. The filtered dirt remains on the surface of the filter cloth 1609. When the filter cloth 1609 moves upward, the dirt enters the guide groove along the surface of the filter cloth 1609, thereby ensuring the cleanliness of the surface of the filter cloth 1609.

[0037] like Figure 4 and Figure 5As shown, a spring rod 1610 is equidistantly mounted on the bottom of the rotating cover 1606, a positioning plate 1611 is mounted between the bottom ends of the plurality of spring rods 1610, a middle portion of the bottom end of the positioning plate 1611 and an output shaft of a driving motor 1612 fixedly mounted on the base 1 are connected via a flat key, a fan blade 1613 is mounted on the outer side of the output shaft of the driving motor 1612 at the top position of the positioning plate 1611 via a flat key, and a top rod 1614 is fixedly mounted on the top end of the output shaft of the driving motor 1612;

[0038] When the spring rod 1610 is used, the rotating cover 1606 can be driven to rise and fall, which changes the difficulty of raising and lowering the rotating cover 1606, and the fan blades 1613 and the rotating cover 1606 are rotated under the action of the driving motor 1612, which changes the difficulty of rotating the rotating cover 1606 and the fan blades 1613, and the top rod 1614 makes the center of the filter cloth 1609 change from a depression to a protrusion, so that the dirt in the middle of the filter cloth 1609 flows to the outside, which changes the difficulty of the dirt flowing.

[0039] like Figure 4 and Figure 5 As shown, four spring rods 1615 are fixedly installed at equal intervals inside the positioning plate 1611, a fixing ring 1616 is clamped and installed between the top ends of the four spring rods 1615, and an arc-shaped collecting box 1617 is clamped and installed on the top end of the fixing ring 1616;

[0040] The spring rod 1615 drives the fixed ring 1616 to move, and at the end of the fixed ring 1616, the arc-shaped collecting box 1617 is driven to rise, so that the arc-shaped collecting box 1617 fits with the bottom of the rotating cover 1606. At this time, when the dirt flowing inside the guide groove enters the arc-shaped collecting box 1617 and is collected by the arc-shaped collecting box 1617, the problem of dust scattering can be prevented.

[0041] Working principle: In actual use of the device, when personnel need to punch two objects with different hole shapes at the same time, the material is placed between the two clamping plates 14, and the two objects are clamped under the action of the cylinder 13 to perform preliminary fixation, and then the hydraulic rod is started to drive the lifting plate 3 to lift and lower the outside of the limit column 2. At this time, when the lifting plate 3 moves, the positioning pin 11 enters the outside of the material and enters the lower die 7 at the same time, and then continues to move so that the pressing block 10 is pressed against the surface of the material. At the same time, the pressing block 10 and the lower die 7 clamp the material, and then the hydraulic rod is started again. At this time, the pressing block 10 is pressed against the material and the lower die 7. The abutment force of the die 7 causes the pressure block 10 to rise along the outer side of the guide column 9, and the return spring 12 is compressed. At this time, the punching rod 8 is exposed inside the pressure block 10, and the surface of the material is punched. Since the lower die 7 is set in three groups, the purpose of punching three materials at the same time is achieved, thereby improving the punching efficiency. The die is a continuous composite die set composed of two independent dies with two hole types, which can complete two or one hole type stamping forming operations at the same time or separately, thereby improving the scope of use and preventing the material from shaking during punching, thereby improving safety. At this time, a punching is formed;

[0042] After the punching is completed, the above-mentioned moving structure is reset, and the material is moved at this time, and then the second part is punched. At this time, the above-mentioned structure is operated again, and the second impulse of punching is performed at this time. During the operation, the piston rod 1602 is driven to enter the piston sleeve 1601 under the action of the pressure block 10. At this time, the gas inside the piston sleeve 1601 is squeezed and enters the connecting sleeve 1604 along the connecting pipe 1603, and drives the lifting rod 1605 to rise inside the connecting sleeve 1604. When the lifting rod 1605 rises, it drives the synchronous plate 1618 to rise. When the synchronous plate 1618 rises, it drives the rotating cover 1606 to rise. When the rotating cover 1606 rises, it drives the spring rod 1610 to stretch. At the same time, when the rotating cover 1606 rises, it drives the grinding sheet 1607 to fit with the bottom end of the punching hole of the material, which can facilitate the fitting of the material and the grinding sheet 1607, and changes the difficulty of fitting the material and the grinding sheet 1607, so as to facilitate the grinding of the material;

[0043] Then, the driving motor 1612 is started. When the driving motor 1612 is running, it drives the positioning plate 1611 to rotate. When the positioning plate 1611 rotates, it drives all the above-mentioned installed structures to rotate. At this time, when the rotating cover 1606 rotates, it drives the grinding sheet 1607 to rotate. When the grinding sheet 1607 rotates, it grinds the bottom end of the punching hole. In this process, the driving motor 1612 drives the fan blades 1613 to rotate. The rotation of the fan blades 1613 induces the gas to flow. When the gas flows, it causes the gas to enter the filter cloth 1609. The filter cloth 1609 absorbs the grinding dirt in the gas, which changes the difficulty of absorbing the grinding dirt, thereby ensuring the cleanliness of the surrounding area of ​​the device.

[0044] After the second punching of the hole, the punching structure is reset, causing the gas pressure inside the piston sleeve 1601 to reset, thereby causing the rotating cover 1606 to descend. When the rotating cover 1606 descends, the filter cloth 1609 inside the rotating cover 1606 contacts the top rod 1614 at the top of the driving motor 1612. During this process, the driving motor 1612 is in a closed state. Then, under the action of the top rod 1614, the center of the filter cloth 1609 is converted from a depression to a protrusion, so that the dirt in the middle of the filter cloth 1609 flows outward, changing the difficulty of the dirt flowing, and the flowing dirt is collected by the arc-shaped collection box 1617;

[0045] Finally, when two holes need to be punched at the same time, the top plate 1 5 and the top plate 2 6 move at the same time, driving the punching rod 8 to punch different holes on the surface of the material.

[0046] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
