Description

A stamping die that can be lifted smoothly

technical field

The utility model relates to the field of stamping dies, in particular to a stamping die which can be lifted smoothly.

Background technique

Stamping die refers to the equipment that uses the die installed on the press to apply pressure to the material to cause separation or plastic deformation to obtain the required parts. At present, in the stamping die, a front guide plate is provided on the upper plate, and the function of the front guide plate is to guide the product before stamping. Before the product is stamped, it needs to be lifted to the required height, and the common defect of the current technology is that when the product is lifted, the product part of the lift pin is lifted, and the product outside the lift pin is lifted. Local products are in a natural hanging state. In this case, the product will swing up and down during feeding, resulting in cut marks on the stamped product, and the accuracy of the product size is relatively low, which increases the production cost. Therefore, the problems existing in the above-mentioned prior art need to be solved urgently.

A front bearing plate is provided, a lifting plate is arranged between the two front guide plates, a first supporting spring is arranged in the base of the lower mold, a sleeve is connected to the top of the first supporting spring, and a sleeve is connected to the top of the sleeve. The upper end is connected with the bottom of the lifting plate, a lifting pin is arranged at the rear of the lifting plate, and a second supporting spring is also arranged in the base of the lower die, and the second supporting spring is connected with the lower end of the lifting pin. Connected, the lifting plate and the lifting pin can support the product to be stamped, and the two sides of the lower die base are correspondingly provided with a first groove matching the support rod.

Further, the adjustable support device includes a support stud, an adjustment nut with a scale and a guide key, and the base of the upper die is provided with a through hole, and one end of the support stud passes through the through hole and is threadedly connected with the base of the upper die , there is a gap between the support stud and the through hole, the end of the support stud close to the punch is provided with a guide key, and the side of the support stud close to the upper surface of the upper die base is threaded with a scale adjustment nut .

Further, a second groove corresponding to the position of the buoyant plate is provided on the front support plate.

Further, the lower formwork is provided with a buoyancy groove located under the buoyancy plate, and the buoyancy groove provides space for the downward pressure of the buoyancy plate.

The beneficial effects of the utility model are:

(1) The utility model increases the supporting force of the product before entering the stamping process, realizes reliable support for the product, ensures that the product enters the stamping die smoothly, not only increases the stability of the stamping product of the mold, but also ensures the stability of the product. It also reduces the amount of adjustment to the feeding platform and improves production efficiency.

(2) The utility model is provided with an adjustable supporting device, and the lower end of the supporting stud is fixedly connected with the punch. When the workpiece needs to adjust the error, as long as the adjusting nut with a scale is turned, the screw thread of the adjusting nut with a scale and the supporting stud can be adjusted. Combined with the restrictive effect of the guide key on the supporting stud, the supporting stud drives the punch to move up and down along the axis, so as to achieve the purpose of transposition for adjusting the height up and down. By turning the scale value of the adjusting nut with scale, the size of the movement of the supporting stud can be accurately determined, so as to achieve the purpose of simple operation and accurate size adjustment.

detailed description

The technical scheme of the present utility model is described below in conjunction with accompanying drawing and embodiment.

Referring to Figure 1, Figure 2 and Figure 3, a stamping die that can be lifted smoothly includes an upper mold base 18 and a lower mold base, and the two sides of the upper mold base 18 are provided with struts 17, This upper mold base 18 is provided with adjustable supporting device and punch 3, and described lower mold base comprises lower template 10, lower backing plate 19 and lower mold holder 11, and the front end of described lower template 11 is provided with two left and right sides. Symmetrical front guide plates 1, the bottoms of the two front guide plates 1 are provided with a front support plate 15, a lifting plate 14 is arranged between the two front guide plates 1, and a first support spring 20 is provided in the base of the lower mold , the top of the first supporting spring 20 is connected with a sleeve 13, and the upper end of the sleeve 13 is connected with the bottom of the lifting plate 14, and a lifting pin 22 is arranged at the rear of the lifting plate 14, and the lower mold base A second support spring 23 is also arranged in the seat, and the second support spring 23 is connected with the lower end of the lift pin 22, the lift plate 14 and the lift pin 22 can support the product to be stamped, and the lower end of the lift pin 22 can support the product to be stamped. Both sides of the mold base 11 are correspondingly provided with first grooves 16 matched with the support rods 17 .

Both sides of the upper die base 18 are provided with struts 17, and both sides of the lower die base 11 are correspondingly provided with first grooves 16 matched with the struts 17. Through this setting, the height of the mold can be adjusted up and down as required. The location is simple and convenient.

In this embodiment, the second groove 12 corresponding to the position of the buoyant plate 14 is provided on the front support plate 15 .

In this embodiment, the lower template 10 is provided with a buoyancy groove 21 located below the buoyancy plate 14 , and the buoyancy groove 21 provides space for the downward pressure of the buoyancy plate 14 .

In this embodiment, the bottom end of the first support spring 20 and the bottom end of the second support spring 23 are both fixed on the lower mold base 11 .

In this embodiment, the upper ends of the two front guide plates 1 are provided with a protruding part 2, and the protruding part 2 can cooperate with the lifting plate 14 to clamp the product.

During operation, the two front guide plates 1 guide the left and right sides of the product before entering the stamping die, so that the product enters the stamping die at the correct position, and the floating plate 14 between the two front guide plates 1 can guide the front guide plate 1 The product part in the center is supported in the height direction, and the product part located at the lift pin 22 is supported and held up by the lift pin 22, which realizes horizontal feeding and makes the product enter the stamping die smoothly.
