Embodiment 1

[0031] see Figure 1-Figure 5 , the present invention provides a burr-free stamping die, the structure of which includes a stamping die 1, a power pressing rod 2, a feeding device 3, and a discharge plate 4, and a power pressing rod 2 is provided at the middle position of the top of the stamping die 1, so that The stamping die 1 is mechanically connected with the power pressure rod 2, the feeding device 3 is installed on the bottom end of the inner side of the stamping die 1, and the left end of the stamping die 1 is provided with a discharge plate 4, and the stamping die 1 It is movably connected with the unloading plate 4;

[0032] The stamping die 1 is composed of an upper die base 1a, an upper backing plate 1b, a stamping mechanism 1c, a guide post sleeve rod 1d, a lower die base 1e, a discharge mechanism 1f, and a buffer support mechanism 1g. The upper die base 1a The bottom end is provided with an upper backing plate 1b, the upper die base 1a is connected with the upper...

Embodiment 2

[0043] see Figure 1-Figure 6 , the present invention provides a burr-free stamping die, the buffer support mechanism 1g is composed of a limit cylinder base 1g1, a thread groove 1g2, a buffer thread rod 1g3, and a buffer gasket 1c4, and the inside of the limit cylinder base 1g1 is There is a thread groove 1g2, the thread groove 1g2 is provided with a buffer thread rod 1g3, the thread groove 1g2 and the buffer thread rod 1g3 are threadedly connected, and the top of the buffer thread rod 1g3 is provided with a buffer gasket 1c4, so The above-mentioned buffer threaded rod 1g3 is glued to the buffer gasket 1c4.

[0044] The upper mold base 1a and the lower mold base 1e are parallel to each other, and the length and width are the same. The top clamping rod 1f21 and the stamping support block 1f5 are fitted together through the tapered extrusion groove 1f51. The buffer gasket 1c4 is made of rubber material, which is not suitable for damage and has strong flexibility. The feeding d...

Abstract

The invention discloses a burr-free stamping die which structurally comprises a stamping die, a power pressing rod, a feeding device and a discharging plate. The stamping die drives an upper die seatto integrally press down to work by using the power pressing rod, an upper backing plate is used for blanking and forming raw materials by using a stamping mechanism, the power pushing rod is used fordriving a circular bending die to perform rotary stamping, the surface of a circular bending workpiece is polished by using a polishing cap so as to polish burrs on the surface of the circular bending workpiece cleanly, the use of components is prevented from being affected, the stamping die clamps the circular bending workpiece in two parts through a stamping supporting block on a discharging mechanism, the situation that the circular bending workpiece is driven to rotate by the polishing cap during polishing, so the polishing efficiency is reduced is avoided, the stamping die limits the downward moving distance of an upper die base by a buffering supporting mechanism, and the stamping supporting block cannot be damaged when a driving device fails.

Description

technical field [0001] The invention relates to the field of molds, in particular to a burr-free stamping mold. Background technique [0002] The existing method of processing and forming of circular curved workpieces is usually completed by the stamping process. The direct and primary factor affecting the height of the workpiece burrs after stamping is the gap between the upper and lower cutting edges, followed by the friction between the pressing material, the sides of the upper and lower cutting edges and the punching section , punching speed, mold use heat, vibration. The traditional burr stamping die cannot effectively remove the burrs generated by the pressed parts and parts, which will affect the use of the parts. If the power machinery of the stamping die fails, it may cause damage to the stamping support block. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical solution...
