Problems solved by technology

[0003] However, since the forming of the central bracket of the stapler needs to go through steps such as punching and multiple bending, the forming process is relatively complicated, and in order to meet the mass demand for the central bracket of the stapler, the mold also needs to realize the automation requirements of mass production, and Today's stamping dies generally have the problems of high difficulty in mass production and low forming precision. Moreover, due to the long structure of the central bracket of the stapler, it is not easy to automatically output parts, which brings many problems to automated production.

Embodiment 1

[0050] see Figure 1 to Figure 6 , the embodiment of the present invention discloses a progressive stamping die for automatic ejection of the central bracket of a stapler, including: an upper die base 1 and a lower die base 2 arranged up and down, a discharge plate 3 and a discharge device 4;

[0051] Among them, the upper mold base 1 and the lower mold base 2 are connected by a guide device 5, the guide device 5 is arranged diagonally, and the guide device 5 is a sliding guide method, and the structure arranged diagonally can better constrain the longitudinal precision of the guide, Good coaxiality;

[0052] The backing plate 6 and the upper mold fixing plate 7 are connected successively below the upper die base 1, the upper die base 1, the backing plate 6 and the upper die fixing plate 7 are fixedly connected by screws, and the backing plate 6 and the upper die fixing plate 7 are installed with The punch group protruding downwards, the punch group includes punching punch gr...

Embodiment 2

[0088] see Figure 1 to Figure 6 , the embodiment of the present invention discloses a forming method for the central bracket of a stapler that is automatically ejected and progressively entered into a stamping die, specifically comprising the following steps:

[0089] Step 1: The automatic feeding device sends the strip material from left to right to the top of the concave template 11 at a constant speed, and controls the feeding direction through the material guide plate;

[0090] Step 2: The upper mold base 1 moves down, and when the unloading plate 3 presses the belt material, the punching punch group 8, the L-shaped bending punch 9 and the U-shaped bending punch 10 contact the belt material, and continue to enter the concave formwork 11 until the mold closing is completed, at this time, the punching punch group 8 completes the profile blanking and punching, the L-shaped bending punch 9 completes the L-shaped bending, and the U-shaped bending punch 10 completes the U-shape...

Abstract

The invention discloses an automatic piece outlet grading stamping die of a book sewer central bracket and a forming method of the automatic piece outlet grading stamping die. The automatic piece outlet grading stamping die of the book sewer central bracket comprises an upper die seat and a lower die seat which are arranged up and down, a material unloading plate and a discharging device. The discharging device comprises an L-shaped bracket, a wedge-shaped sliding block, a torsion spring, a supporting seat, a pushing piece plate and a pushing plate reset spring, one side of the L-shaped bracket is fixed to the upper die seat, the other side of the L-shaped bracket faces down, the wedge-shaped sliding block is hinged to an end head through the torsion spring, the supporting seat is fixed tothe lower die seat, a through groove is formed in the upper end head of the supporting seat, the pushing piece plate horizontally penetrates through the through groove, an L-shaped bending structureis arranged in front of the pushing piece plate, a clamping ring is formed in the rear of the pushing piece plate, the pushing plate reset spring is arranged between the clamping ring and the supporting seat, a grading punching mode and the automatic discharging device are adopted, batch production and automatic discharging are realized, and the production efficiency and the automatic degree are high.

Description

technical field [0001] The invention relates to the technical field of stamping dies, and more specifically relates to a progressive stamping die and a forming method thereof for the central bracket of a stapler with automatic ejection. Background technique [0002] At present, the stapler is a commonly used office item. In the overall structure of the stapler, the central bracket is an important component, which mainly plays a supporting role. It requires high stability and a certain compressive strength. The central bracket of the stapler is generally formed by stamping a mold. With the rapid development of society, the use of staplers is becoming more and more extensive, and the development of stamping dies for the central bracket of the stapler is also getting faster and faster. [0003] However, since the forming of the central bracket of the stapler needs to go through steps such as punching and multiple bending, the forming process is relatively complicated, and in or...
