Description

Progressive die with in-die tapping device

technical field

The utility model relates to a die, in particular to a progressive punch die with an in-mold tapping device.

Background technique

There are quite a few sheet metal stamping products that need to have wire holes. At present, the process of processing such sheet products with wire holes is relatively complicated. First, it must be stamped on the punching machine through a mold to form a sheet of the required shape, and then use tapping. The machine taps the stamped sheet. The two operations of silk are time-consuming and labor-intensive, and the processing cost is high.

Contents of the invention

The purpose of the utility model is to provide a progressive punching die with an in-mold tapping device that saves time and labor, and can be synchronously stamped and tapped to reduce processing costs, so as to overcome the deficiencies of the prior art.

The utility model has a progressive punching die with an in-mold tapping device, comprising a lower mold consisting of a lower backing plate, a foot and a lower mold base, and an upper mold consisting of an upper mold mounting plate and an upper mold base; on the lower mold base The fixed plate is fixed, the spring is located in the hole on the fixed plate and supported between the lower mold base and the supporting plate above the fixed plate, and there are symmetrical guide plates on both sides of the supporting plate; fixed on the supporting plate There are guide pillars, which match the guide pillar holes on the lower mold base; there are limit bolts between the fixed plate and the supporting plate; several tapping machines are installed above the lower mold base, and the main shaft of the tapping machine is vertical Set and located above the supporting plate; the upper end of the driving screw on the tapping machine is fixedly connected with the upper die base; the driving screw is matched with the connection between the lower die base, the feet and the lower backing plate through the guide hole; installed on the upper die A cavity capable of accommodating a tapping machine is arranged on the plate and the upper die base.

The utility model has a progressive punching die with an in-mold tapping device. When punching, the upper die moves down, and the plate on the supporting plate can be punched and formed through the clamping of the upper die and the lower die. During the punching process, the spring Compressed, the supporting plate moves down and falls on the fixed plate. During this process, the driving screw of the tapping machine moves down with the upper die, and drives the nut and gear transmission mechanism that match the driving screw to rotate the main shaft of the tapping machine. , the spindle drives the tapping tap installed at the end to tap the plate, and the upper die moves down once to complete both the stamping action and the tapping action. Compared with the prior art, it saves time and effort, and the stamping and tapping are carried out synchronously, which reduces the processing cost.

Detailed ways

As shown in Figure 1: this mold comprises the lower mold that is made up of lower backing plate 1, leg 2 and lower mold base 3 and the upper mold that is made up of upper mold mounting plate 6 and upper mold base 7.

On the lower mold base 3, a fixed plate 18 is fixed by connecting bolts 13, and the quantity of the connecting bolts 13 can be determined according to the mold specifications, as long as the fixed plate 18 is firm. The springs 11 are located in the holes on the fixed plate 18 and are supported between the lower mold base 3 and the supporting plate 16 above the fixed plate 18, and the springs 11 are evenly distributed. Symmetrical guide plates 14 are fixedly connected to both sides of the upper side of the supporting plate 16 by bolts. There is a gap between the inner side of the guide plate 14 and the supporting plate 16, the gap is greater than the thickness of the punched plate, and the thickness of the punched plate and the size of the gap are determined according to the specific workpiece to be processed.

A guide post 10 is fixed on the support plate 16 , and the guide post 10 and the support plate 16 can be an interference fit. The guide post 10 is matched with the guide post hole 19 on the lower mold base 3, and can move axially in the guide post hole 19. The number of guide posts 10 is four, which are evenly distributed at the four corners of the supporting plate 16 .

A limit bolt 12 is arranged between the fixing plate 18 and the supporting plate 16 , and the limiting bolt 12 protrudes upward from the hole on the fixing plate 18 and is threadedly connected with the supporting plate 16 . After installation, ensure that the spring 11 has a certain pretightening force, and at the same time, the upward movement of the supporting plate 16 under the action of the spring 11 is limited.

Can pass through bolt to be fixedly installed with several tappers above the die base 3, comprise two right tappers 4 on the right side and a left tapper 9 on the left side. The number of tapping machines is determined according to the workpiece. The main shaft of every tapping machine is vertically arranged and is positioned at the top of supporting plate 16. The upper end of the driving screw rod 5 on the tapping machine is fixedly connected with the upper die base 7 . The driving screw 4 is matched with the lower mold base 3, the supporting pin 2 and the lower backing plate 1 through the guide hole 17. A cavity 8 capable of accommodating a tapping machine is provided on the upper die mounting plate 6 and the upper die base 7 .

The tapping machine mentioned above is optional.

When stamping, the upper mold moves down, and the plate 20 on the supporting plate 16 can be stamped and formed through the clamping of the upper mold and the lower mold. During the stamping process, the spring 11 is compressed, and the supporting plate 16 moves down and falls on the fixed surface. On the plate 18, during this process, the driving screw 5 of the tapping machine moves down with the upper die, and drives the nut and gear transmission mechanism matched with the driving screw to rotate the main shaft of the tapping machine, and the main shaft drives the tapping tap installed at the end. Tapping the plate 20, the tapping machine is located in the cavity 8 after the mold is closed, and does not affect the stamping. A downward movement of the upper mold not only completes the stamping action, but also completes the tapping action. Compared with the prior art, it saves time and effort, and the stamping and tapping are carried out synchronously, which reduces the processing cost.
