Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of stamping die, in particular to a stamping die of stamping equipment and a material removal method. BACKGROUND

[0002] The stamping die is a special process equipment for processing materials (metal or non-metal) into parts (or semi-finished products) in cold stamping processing, which is called cold stamping die (commonly known as cold stamping die). Stamping is a kind of pressure processing method that uses the die installed on the press to apply pressure to the material to make it separate or plastically deform, so as to obtain the required parts at room temperature. After the workpiece is stamped and formed, the stamped and formed workpiece needs to be removed from the die. At present, most of the automatic workpiece ejection is realized on the market to realize automatic material removal of the workpiece.

[0003] However, in the prior art, the stamping die directly ejects the formed workpiece by using a ejector pin or a ejector rod. However, the force is concentrated in the same position when the ejector pin or the ejector rod ejects, so that the workpiece is ejected, but the concentrated ejection force causes the ejection position of the workpiece surface to be concave or convex, which damages the surface of the stamped workpiece and reduces the stamping quality of the workpiece. In addition, when the punch bottom contacts the workpiece during stamping, dirt, grease, metal chips and other impurities are easily accumulated on the surface of the punch, which increases the friction between the material and the punch, making it difficult to remove the material. Therefore, it is necessary to provide an automatic material removal method for a high-efficiency stamping die to solve the above problems. SUMMARY

[0054] In combination with the preferred embodiments, the working principle of the present application is as follows:

[0055] When working:

[0056] After the workpiece is placed on the concave die 7, the upper die holder 5 is pushed down by starting the hydraulic cylinder 4, the synchronous downward movement of the fixed convex die 6 is driven by the downward movement of the upper die holder 5, and the synchronous downward movement of the cleaning assembly fixed on one side is driven by the downward movement of the upper die holder 5, the inside of the convex die 6 is continuously pushed by the hydraulic cylinder 4, so that the workpiece on the concave die 7 can be formed by stamping, and the upper die holder 5 and the concave die 7 are in contact when the convex die 6 slides into the concave die 7, and the push plate 1007 is pushed down by the compression spring 1006 when the upper die holder 5 slides down, the extension rod 1008 is pushed down by the push plate 1007, and the support plate 1009 is pushed down by the extension rod 1008, so that the bottom of the support plate 1009 is in contact with the surface of the workpiece when the cleaning assembly slides down, so that the workpiece can be limited in position. Because the gear 1003 and the fixed rack 1002 are engaged, the gear 1003 can rotate on the fixed rack 1002 during the downward movement, the fixed bidirectional screw rod three 1011 is driven to rotate synchronously when the gear 1003 rotates, the two adjusting sleeves 1004 slide in opposite directions under the action of the bidirectional screw thread on the bidirectional screw rod three 1011, the mounting rod 1005 slides synchronously when the adjusting sleeve 1004 slides, and the internal compression spring two 1006, the push plate 1007 and the extension rod 1008 slide simultaneously when the mounting rod 1005 slides, and the support plate 1009 and the cleaning cotton wipe 1010 on the upper surface of the support plate 1009 slide synchronously when the extension rod 1008 slides in the opposite direction, the cleaning cotton wipe 1010 is in contact with the bottom of the convex die 6, so that the impurities and debris adhered to the bottom of the convex die 6 can be cleaned regularly, and the extension rod 1008 is retracted into the mounting rod 1005 under the action of the downward movement when the upper die holder 5 and the concave die 7 are in contact, so that the compression spring two 1006 is compressed, and the support plate 1009 and the cleaning cotton wipe 1010 are moved to the two sides of the upper die holder 5, so that the support plate 1009 and the cleaning cotton wipe 1010 do not affect the stamping effect of the workpiece during stamping, and the cleaning of the convex die 6 can effectively reduce the friction between the convex die 6 and the workpiece, reduce the adhesion between the convex die 6 and the workpiece, prolong the service life of the mold, and improve the stripping effect;

[0057] After the workpiece is punched, the driving motor 801 is started to drive the bidirectional screw rod 802 to rotate, the rotation of the bidirectional screw rod 802 drives the synchronous rotation of one of the belt pulleys 804 on the surface, and the other belt pulley 804 is driven to rotate under the action of the belt 805, the rotation of the belt pulley 804 drives the synchronous rotation of the internally fixed bidirectional screw rod 803, so that the two moving sleeves 806 can be pushed to slide to the middle under the action of the bidirectional threads on the bidirectional screw rod 802 and the rotating support 807, the two connecting rods 808 can be pushed to slide up when the two connecting rods 808 rotate, and the two ejector rods 809 can be synchronously slid up through the two connecting rods 810, so that the top ejector plate 811 can be synchronously slid up through the synchronous sliding of the two ejector rods 809, and the workpiece punched on the ejector plate 811 can be automatically ejected through the upward sliding of the ejector plate 811, and the ejector plate 811 can uniformly eject the workpiece from the point, so that when the workpiece is ejected, the ejection force is effectively avoided from being concentrated in one position, and compared with the prior art of ejecting the workpiece from one point, the quality of the workpiece stripping is improved, the workpiece depression or the existence of the vertex is avoided, and thus the workpiece stripping effect is effectively improved.

[0058] When the workpiece on the ejector plate 811 is punched, the ejector plate 811 slides down with the punched workpiece, and the moving rod 905 slides down when the ejector plate 811 slides down, the sliding sleeve 902 slides on the sliding rod 901 driven by the sliding down of the moving rod 905, and the compression spring 904 on the sliding rod 901 is compressed when the sliding sleeve 902 slides, and then the sliding sleeve 902 is pushed up by the reset spring force of the compression spring 904 when the workpiece is automatically ejected after punching, so that the moving rod 905 and the ejector plate 811 fixed on one side are synchronously slid up, so that the ejection force of the workpiece is further increased, and the workpiece stripping efficiency is further improved, and when the ejector plate 811 slides up, the magnetic block one 906 and the magnetic block two 907 are in repelling state by the principle of repelling same poles and attracting different poles, and the ejection force is further increased by the repelling force of the magnet, so that the workpiece punched on the ejector plate 811 is automatically ejected, and the workpiece stripping efficiency is further improved.

[0059] Embodiment two

[0060] A workpiece stripping method of a punching die of a punching device, comprising the following steps:

[0061] Step one: after the un-punched workpiece is prevented on the die 7, the hydraulic cylinder 4 is started to push the upper die seat 5 and the punch 6 to punch and form the workpiece;

[0062] Step two: the punch formed workpiece will stay in the die 7 under the action of the punch force, then the hydraulic cylinder 4 is closed, the upper die holder 5 and the punch 6 are reset, and the punch formed workpiece is automatically ejected by the starting of the ejector plate 811;

[0063] Step three: the magnet block one 906 and the magnet block two 907 are in repelling state by the principle of repelling same poles and attracting opposite poles, and the repelling force of the magnet further increases the ejection force, so that the punch formed workpiece on the ejector plate 811 is automatically ejected;

[0064] Step four: the reset rebounding force of the multiple compression springs one 904 can increase the ejection force again, so that the punch formed workpiece in the die 7 is quickly ejected;

[0065] Step five: the impurities and debris on the bottom of the punch 6 are cleaned, which can effectively reduce the friction between the punch 6 and the workpiece, so that the punch formed workpiece and the punch 6 can be effectively prevented from sticking together by reducing the friction between the punch 6 and the punch formed workpiece.
