Description

A kind of novel stretching die

Technical field

The utility model is related to mould applications, more particularly to a kind of novel stretching die.

Background technology

With the rapid development of machinery industry, some engineering goods are widely used in daily life, and these The processing of engineering goods is frequently necessary to use various drawing dies.Lifting Device is largely all set in existing drawing die Meter is in mold bottom, and complicated, dismounting difficulty, especially ejector beam lever arm is long causes the entire relatively low length of mold production efficiency Time can cause inter deterioration serious after.In addition existing drawing die is to provide power by hydraulic test, causes to draw It stretches that the open mold speed of mold is relatively slow, molding is unstable, makes the second-rate of converted products.

Invention content

The stable novel stretching die of fast and molding the purpose of this utility model is to provide a kind of open mold speed.

The purpose of this utility model is achieved through the following technical solutions：

A kind of novel stretching die, including upper die holder and lower die holder are equipped with swaging die, the pressure between upper die holder and lower die holder Expect that mould is mounted on by pneumatic springs on lower die holder, swaging die both sides are equipped with lifting die shank, and balance weight is machined at the top of swaging die And positioning plate, balance weight are mounted on swaging die quadrangle, positioning plate setting is machined with through-hole in the middle part of swaging die both sides, swaging die, Lower mold core is equipped in the middle part of the lower die holder, lower mold core is contacted across through-hole with upper die holder, be machined on the upper die holder bottom surface and The side wall of the upper mold core that lower die core profile matches, upper die holder is equipped with more reinforcing ribs, and upper die holder both sides are equipped with and swaging die The outer guide plate being in contact.

Backplate is installed on the side wall of the lower die holder.

The utility model has the following effects that：

(1) by the way that pneumatic springs are arranged, the opening speed of upper die holder can be improved, to improve production efficiency；

(2) by the way that balance weight is arranged, it is ensured that mold clamping is steady, to improve the Forming Quality of product；

(3) by the way that backplate is arranged, when can prevent from demoulding, workpiece, which flies out, damages worker.

Specific implementation mode

Embodiment

As shown in Figure 1 to 4, novel stretching die provided in this embodiment includes upper die holder 1, swaging die 2 and lower die holder 3, Swaging die 2 is arranged between upper die holder 1 and lower die holder 3, and the swaging die 2 is mounted on by pneumatic springs 21 on lower die holder 3, pressure Expect that 2 both sides of mould are equipped with lifting die shank 22,2 top of swaging die is machined with balance weight 23 and positioning plate 24, and balance weight 23 is mounted on pressure Expect four angles of mould 2, for the setting of positioning plate 24 in 2 both sides of swaging die, 2 middle part of swaging die is machined with through-hole, 3 middle part of the lower die holder Equipped with lower mold core 31, lower mold core 31 is contacted across through-hole with upper die holder 1, is equipped with backplate 32 on the side wall of lower die holder 3, it is described on The upper mold core 11 to match with 31 profile of lower mold core is machined on 1 bottom surface of die holder, the side wall of upper die holder 1 is equipped with more reinforcing ribs 12,1 both sides of upper die holder are equipped with the outer guide plate 13 being in contact with swaging die 2.

The application method of the utility model is：

Steel plate to be tensioned is mounted on swaging die 2 first, then controls 1 downlink of upper die holder, when 1 downlink of upper die holder with Swaging die 2 contacts, and the pneumatic springs 21 of 2 bottom of swaging die slow down the power of 1 downlink of upper die holder generation, while lower mold core 31 and upper mold Core 11 stretches steel plate, and subsequent upper die holder 1 continues uplink, and the pneumatic springs 21 on swaging die 2 restore to the original state, and drive simultaneously Swaging die 2 moves up, the steel plate after ejection stretches while swaging die 2 moves up.

The above is only the utility model preferred embodiment, but the scope of protection of the utility model is not limited to This, any transformation carried out based on technical solution provided by the utility model and inventive concept and replacement should all be covered in this reality With in novel protection domain.
