Description
Technical Field
The invention relates to the field of stamping dies, in particular to a sheet metal part precise stamping die.
Background
The casting cold stamping die is the die with highest requirements, highest processing difficulty and greatest processing amount in the automobile body manufacture, the hole flanging ejector accounts for about 10% of the die, the existing hole flanging ejectors are complex in structure and are driven by springs to eject upwards, ejection force is small, and ejection is incomplete easily, so that the problem is very important to solve.
Disclosure of Invention
The invention aims to provide a hole flanging ejector, which is characterized in that a standard screw is fixed on a die body, and a hole flanging ejector block is moved to enable the standard screw to be ejected upwards, so that the problems of complex structure and small ejection force of the existing hole flanging ejector are solved.
The invention provides a hole flanging ejector which comprises a die body, wherein a standard screw is arranged on the die body, a hole flanging ejector block is arranged above the die body, a hole flanging is arranged in the middle of the hole flanging ejector block, a limiting groove is formed in the lower side of the hole flanging, the upper end of the standard screw extends into the hole flanging ejector block, the limiting groove limits the upper end of the standard screw, a standard spring is sleeved on the standard screw, and the standard spring is arranged between the die body and the hole flanging ejector block.
The further improvement is that: the upper end of the standard screw is provided with a gasket.
The further improvement is that: the lower end of the standard screw is provided with a thread section, and the standard screw is connected with the die body through threads.
The further improvement is that: the outer side of the flanging ejection block is sleeved with a spring.
The invention has the beneficial effects that: the standard screw is fixed on the die body, and the hole flanging ejection block is moved to enable the standard screw to be ejected upwards, so that ejection force is effectively improved, the structure is simpler, and assembly and use are convenient; the standard screw is sleeved with the standard spring, the standard spring rapidly ejects the hole flanging ejection block to reset, and the spring is arranged on the outer side of the hole flanging ejection block, so that Zhang Kaifu potential energy is further improved, and the hole flanging ejection block is supported from the lower side.

Fig. 1 is a schematic diagram of the present invention.
Wherein: the die comprises a die body 1, a standard screw 2, a 3-hole flanging ejection block, a 4-hole flanging ejection block, a 5-limit groove, a 6-standard spring, a 7-gasket, an 8-thread section and a 9-spring.
Detailed Description
The present invention will be further described in detail with reference to examples, which are provided for the purpose of illustration only and are not intended to limit the scope of the present invention.
As shown in fig. 1, this embodiment provides a hole flanging ejector, including mould body 1, be equipped with standard screw 2 on the mould body 1, mould body 1 top is equipped with hole flanging ejector block 3, be equipped with hole flanging 4 in the middle of the hole flanging ejector block 3, hole flanging 4 downside is equipped with spacing groove 5, standard screw 2 upper end stretches into in the hole flanging ejector block 3, spacing groove 5 carries out spacingly to standard screw 2 upper end, cover is equipped with standard spring 6 on the standard screw 2, standard spring 6 sets up between mould body 1 and hole flanging ejector block 3, hole flanging ejector block 3 pushes down and makes standard spring 6 compress, standard screw 2 stretches out and ejects, standard spring 6 opens and drives hole flanging ejector block 3 reset after the ejection is accomplished. The upper end of the standard screw 2 is provided with a gasket 7. The lower extreme of standard screw 2 is equipped with screw thread section 8, and standard screw 2 passes through threaded connection with mould body 1, through threaded connection, the installation of being convenient for uses. The spring 9 is sleeved on the outer side of the flanging ejection block 3, the spring 9 supports the flanging ejection block 3 from the outer side, and meanwhile the opening reset effect is further improved.
