Preferably, the bottom of described cofferdam correction wall also has one section of vertical wall.

Preferably, the vertical wall in described cofferdam is in same vertical with the plurality of die cavity near the inwall of the die cavity in described cofferdam Face.

Preferably, described cofferdam removably connects with described lower mold.

Preferably, it is provided with reclinate bending section at the bottom of the chamber of described die cavity.

Preferably, described die is provided with the lobe matched with described bending section.

Preferably, when described cylinder resets, described lower mold is in level.

Orderly, described cylinder drives the described lower mold anglec of rotation more than 90 °.

This utility model compared with prior art, has the advantages that

Employing cofferdam coordinates with groove, can easily realize die and accurately key in the purpose of die cavity, in addition cofferdam loudspeaker dress inwall, Key in die cavity at die initial, the effect of correction position can be played, steady when making die key in, noise is little, accurate；

Having multiple die cavity in a cofferdam, can process multiple spring leaf successively, working (machining) efficiency is high, time saving and energy saving；

The dismountable fixed form in cofferdam, it is simple to safeguard and change, simple to operation；

Use cylinder to drive lower mold reversion, make spring leaf be free to fall in collecting box, time saving and energy saving, and safety.

Accompanying drawing explanation

Fig. 1 is the structural representation of this utility model lower mold；

Fig. 2 is the structural representation of this utility model upper mold.

Detailed description of the invention

By making, architectural feature of the present utility model and effect of being reached are had a better understanding and awareness, in order to preferably Embodiment and accompanying drawing coordinate detailed description, are described as follows:

As shown in Figure 1 and Figure 2, a kind of diel being easy to collect spring leaf, mould includes lower mold 1, upper mold 2.Lower mold 1 is provided with the multiple die cavitys 11 accommodating spring leaf, multiple die cavity 11 word orders, or is arranged in other formation.Upper mold The lower surface of 2 is provided with the die 21 corresponding with the quantity of die cavity 11 and position.According to treating the bending requirement of processed springs sheet, Reclinate bending section 111 can be set in die cavity 11, arrange and bending section 111 kissing in the relevant position of die 21 The lobe 22 closed.When after 2 times pressures of upper mold, in lobe 22 with under the cooperation of bending section 111, complete the bending of spring leaf. Bending section 111 and the shape of lobe 22, depending on actual processing request.

Under long-term punching press, upper mold 2 and lower mold 1 are susceptible to left and right or move forward and backward, and cause the die 21 cannot accurate key Entering in die cavity 11, cause bigger noise, simultaneously as prior art processing single processing often, work efficiency is low. In order to avoid this situation occurs, this utility model is formed around cofferdam 3 at multiple die cavitys 11, and the outer wall in cofferdam 3 is vertical wall, Inwall has trumpet-shaped correction wall 32, the mould intracavity wall near cofferdam 3 and the mild mistake of inwall in cofferdam 3 in multiple die cavitys 11 Cross and be integrated.Multiple dies 21 be formed around groove 23, groove 23 is corresponding with cofferdam 3.When upper mold is pressed for 2 times, many Individual die 21 falls in die cavity 11 after 32 times pressures of horn-like correction wall in cofferdam 3, and cofferdam 3 is keyed in groove 23.

Cofferdam 3 inwall is integrated with die cavity 11 inwall gentle transition, and specially cofferdam 3 is near the inwall of the certain altitude of bottom For vertical wall 31, vertical wall 31 is in same vertical with the inwall of the die cavity 11 near cofferdam 3.I.e. when multiple dies 21 After depressed key enters the correction wall 32 in cofferdam 3, the inclined wall along correction wall 32 slides to the vertical wall 31 in cofferdam 3 gradually, finally Accurately keying in die cavity 11, this process, noise is little, and stamping position is accurate.

After Multi-step forming, certain damage is caused in cofferdam 3, for the ease of safeguarding, the cofferdam 3 that this utility model provides Removably connect with lower mold 1.The purpose being convenient for changing can be realized.

Owing to spring leaf is in die cavity, die cavity has certain depth, and the spring leaf after processing takes out more bothersome, especially Being the multiple spring leaf of time processing, the most manually pick up spring leaf, efficiency is excessively beneath.For the ease of taking out spring leaf, This utility model also devises switching mechanism in the bottom of lower mold.

Switching mechanism includes that frame 5, lower mold 1 include fixed edge 12 and rotate limit 13；Fixed edge 12 is relative with rotating limit 13； Fixed edge 12 rotates and is fixed in frame 5；Rotate limit 13 and be fixed with at least one cylinder 4；The push rod of cylinder 4 and rotation limit 13 is hinged.Cylinder 4 is not when working, and when being i.e. in reset state, lower mold 1 is level, after cylinder 4 starts, Cylinder 4 drives lower mold to be rotated up with fixed edge 12 for rotating shaft.Cylinder 4 drives lower mold 1 anglec of rotation more than 90 °, in order to The spring leaf in die cavity 11 is made freely to fall in collecting box.The quantity of cylinder 4 can be come according to the weight of lower mold 1 and length Set.

Of the present utility model ultimate principle, principal character and of the present utility model advantage have more than been shown and described.The industry Skilled person will appreciate that, this utility model is not restricted to the described embodiments, described in above-described embodiment and description only Being principle of the present utility model, on the premise of without departing from this utility model spirit and scope, this utility model also has various change Changing and improve, these changes and improvements both fall within the range of claimed this utility model.The guarantor that this utility model requires Scope of protecting is defined by appending claims and equivalent thereof.
