Description
Technical field
The present invention relates to a kind of stripper apparatus, be applicable to the production technology of thin-walled deep drawing spare, be particularly useful for the processing technology of pop can.
Background technology
The stripper apparatus of existing deep drawing spare mainly is a tank withdrawing device.Tank withdrawing device adopts the shape guiding, forces to move back jar.For the bigger product of wall thickness, this multijaw tank withdrawing device is very helpful for the demoulding, however the can body wall thickness of pop can only have about 0.07mm, it is wrinkling that bigger pressure can cause jar type oral area unstability during the demoulding, influences product quality.
For the production process of thin-walled deep drawing spare, its jar type release problems behind process deep drawing or ironing is the technological difficulties in producing always.And cause jar reason of a type demoulding difficult problem to mainly contain two: the one, because the unique shape of pop can jar type causes.For two-sheet zip-top can, blank for guaranteeing carrying out smoothly of this technology, need design jar type oral area bigger than the wall thickness at tank skin place through reducing and flanging process through needing behind the ironing.And because the die shape of ironing and the restriction of deformation technique, a jar type oral area is inwardly held tightly on punch behind the blank ironing, and this has just increased the difficulty of the demoulding.The 2nd, because the pop can wall thickness, the wrinkling possibility of jar type unstability increased when resemblance that can body is high made the demoulding.Therefore, should guarantee the smooth demoulding of jar type during the pop can demoulding, also will guarantee the complete of jar type, prevent that unstability is wrinkling.
Summary of the invention
The objective of the invention is in order to solve the demoulding difficult problem of thin-walled deep drawing spare in the actual production, and guarantee the stable of jar type structure in the workpiece knockout course, a kind of novel stripper apparatus is provided.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of thin-walled deep drawing spare technology stripper; mainly comprise: the socket successively from top to bottom of discharging circle 2, guide tube 3, threaded collar 4; elastic tape 6 hoops are fixing in the U of discharging circle 2 type groove; spring 7 is installed in threaded collar 4 upper support guide tubes 3; taper hole seat 1 entangles remaining part; agree with screw thread and threaded collar 4; it is characterized in that; discharging circle 2 inwalls have step-like structure 13 near the upper port place; form inward flange 14 and secondary support surface 15, can the wrinkling problem of unstability in knockout course, can not occur by the protective pot mouth.According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that discharging circle 2 is made up of 8 unloading block 5 splicing, fix in the U-shaped circle by elastic tape 6, can be by the stretching of elastic tape 6 and the contraction resultant motion of loosing.
According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that the flange inclined-plane 8 of discharging circle 2 contacts cooperation with the inclined-plane 9 of taper hole seat 1, can slide over each other.
According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that the internal diameter of secondary support surface 15 is than the little 0.04-0.06mm of processed workpiece external diameter.
According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that guide tube 3 upper surfaces 11 contact cooperation with discharging circle 2 surfaces 12, can slide over each other.
According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that by spring 7 support fixation, spring 7 is installed on the surface 10 of threaded collar 4 between guide tube 3 and the threaded collar 4, auxiliary discharging circle 2 foldings.
According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that, locate by screw thread between threaded collar 4 and the taper hole seat 1.
According to thin-walled deep drawing spare technology stripper of the present invention, it is characterized in that the bottom diameter of threaded collar 4 is shaped as hexagon.
Because used the design of unique splicing unloading block and inward flange, the present invention can significantly reduce the demoulding difficulty of 500ml steel can, can prevent the pressurized unstability of jar type oral area in knockout course again effectively.

The specific embodiment
Embodiment one
This thin-walled deep drawing spare technology is as follows with the mounting means of stripper: 8 unloading block piece together circle as shown in Figure 3, and are fixing with elastic tape 6 in the U-lag of flange, form discharging circle 2 shown in Figure 5.The flange inclined-plane 8 of discharging circle 2 contacts cooperation with the inclined-plane 9 of taper hole seat 1 shown in Figure 6, and these two faces need lower roughness, and coefficient of friction is less, can slide mutually at an easy rate.Unloading block is adding man-hour, require its inward flange mouth diameters than ironing after about the little 0.05mm of external diameter of workpiece.Guide tube 3 as shown in Figure 7, the upper surface 11 of guide tube 3 contacts cooperation with the surface 12 of discharging circle 2, also requires both to have lower roughness, can slide mutually.Discharging circle 2 is located thus.By spring 7 support fixation, spring 7 is installed on the surface 10 of threaded collar shown in Figure 84 between guide tube 3 and the threaded collar 4 shown in Figure 8, plays a part to support and regulates discharging circle 2 lengthwise positions.Locate by screw thread between threaded collar 4 and the taper hole seat 1.Close for making things convenient for screw thread to twist, the lower end of threaded collar 4 is designed to hexagon.The integral installation structure chart is seen Fig. 1.
Embodiment two
Motion mode when this thin-walled deep drawing spare technology is worked with stripper is specially: after ironing was finished, punch drove a jar shape thin-wall workpiece and enters discharging circle 2 from top to bottom.When workpiece passes through inward flange 14 (shown in Figure 3), because discharging circle 2 inward flange diameters are littler than workpiece external diameter, discharging circle 2 stressed spreadings, discharging circle 2 outer flange surface 8 along taper hole seat 1 inclined-plane 9 to lower slider, surface 12 radially slides along guide tube 3 upper surfaces 11, promotes guide tube 3 to lower compression spring 7.After workpiece is fully by discharging circle 2 inward flanges 14, the radial expansion force removal that discharging circle 2 is suffered, elastic tape 6 shrinks, spring 7 elongations, and the mutual slip between above-mentioned two pairs of surfaces is opposite, and 8 unloading block return to close-fitting state.
When punch drives workpiece and moves upward because discharging circle 2 inward flange diameters are littler than the external diameter of workpiece, secondary support surface 15 (shown in Figure 3) thus will block workpiece stops workpiece to continue to move upward to make workpiece break away from punch.Because this thin-walled deep drawing spare technology architectural feature of stripper, discharging circle 2 can radially expand outwardly in the knockout course, the unloading block secondary support surface 15 (shown in Figure 3) of unique design will support a jar mouth this moment, neither can produce compression to tank skin increases demoulding difficulty, can guarantee jar stability of mouth in knockout course again.
