Shaking when flexible, thus avoid generating unnecessary shaking when expander mold 31 is mobile, when raising expander mold 31 is mobile
Stability.
Referring to Fig.1, lower die 22 is provided with limit assembly 5 far from one end of expander mold 31, and limit assembly 5 includes adjustable plate
52.The plate structure that adjustable plate 52 is vertically arranged, bottom are fixed on workbench 11, the mobile side on surface and expander mold 31
To vertical, one end close to expander mold 31 is provided with adjusting screw rod 51.Adjusting screw rod 51 is horizontally disposed screw shaped, axis
It is vertical with the surface of adjustable plate 52, adjustable plate 52 is passed through close to one end of adjustable plate 52 and is threadedly coupled with it, far from adjustable plate
52 one end is provided with limit plate 53.
The plate structure that limit plate 53 is vertically arranged is arranged in parallel with adjustable plate 52, close to the side of adjusting screw rod 51
It is rotatablely connected with adjusting screw rod 51.In use, side of the limit plate 53 far from adjusting screw rod 51 is abutted with one end of workpiece 6.The
When two cylinders 32 drive expander mold 31 to close to the movement of the direction of lower die 22, since the diameter of expander mold 31 is greater than workpiece 6
Diameter so that active force of the workpiece 6 by expander mold 31 leans on it at this point, limit plate 53 can limit the position of workpiece 6
One end of nearly limit plate 53 will not be moved because of by active force, improve the stability for placing workpiece 6, to realize that expander is grasped
Make.
In conjunction with Fig. 3, the bottom of limit plate 53 is provided with sliding block 531, is provided on workbench 11 and 531 phase of sliding block
The length direction of the gliding groove 111 matched, gliding groove 111 is consistent with the axis direction of adjusting screw rod 51.Review Fig. 1, adjusting screw rod
51 are provided with handle 511 close to one end of adjustable plate 52.
When needing to process the workpiece 6 of different length, handle 511 can be turned, drives adjusting screw rod 51 to close to or far under
The direction of mould 22 is mobile, at this point, limit plate 53 also does equidirectional movement.When 6 length of workpiece is shorter, can by limit plate 53 to
It adjusts close to the direction of lower die 22, when 6 length of workpiece is longer, limit plate 53 can be adjusted to the direction far from lower die 22, with
It is applicable in the workpiece 6 of different length.
The implementation principle of the present embodiment are as follows:
When needing workpieces processing 6, workpiece 6 is put in lower die 22 first, the top of lower die 22 and the bottom of workpiece 6 are supported
It connects, then turns the position that adjusting screw rod 51 adjusts limit plate 53, so that the one end and limit plate 53 of workpiece 6 close to limit plate 53
It abutting, the first cylinder 231 drives upper mold 23 to move down, until the bottom of upper mold 23 is abutted with the top of workpiece 6, the second cylinder
32 drive direction movement of the expander mold 31 to close lower die 22 again, until workpiece 6 is inserted into one end of 31 closing of expander mold
It is interior, it continues to move to, so that one end that expander mold 31 is relatively large in diameter also enters inside workpiece 6, the diameter of 6 end of workpiece is expanded
Greatly；During whole operation, one end of workpiece 6 is tightly abutted with limit plate 53, so that workpiece 6 will not in the horizontal direction arbitrarily
It is mobile, achieve the effect that improve 6 stability of workpiece.
The embodiment of present embodiment is the preferred embodiment of the utility model, and not limitation is originally practical new according to this
The protection scope of type, therefore: the equivalence changes that all structures, shape, principle according to the utility model are done should all be covered by practical
Within novel protection scope.
