Description

Technical Field

[0001] The present invention relates to the field of punch die design and other mechanical manufacturing technologies, and more specifically to a material dragging assembly used in the punching of a cutting die and a waste material utilization mechanism having the assembly. Background Art

[0002] The automobile manufacturing industry has very high requirements for reducing material waste and improving material utilization. Therefore, in mold design, it is required to improve the design level as much as possible to improve material utilization, save costs, and create greater profits for the company.

[0003] In the prior art, the cutting die used in the production is a strip of material cut by a shearing machine. When the strip is produced to the last piece, the weight of the part is heavier than the waste material, the strip cannot be placed steadily, and the last part cannot be cut, resulting in a waste of raw materials and causing heavy losses to the company.

[0004] Therefore, how to design a material dragging component and a waste material utilization mechanism having the component to solve such waste problems has become a problem that technical personnel in this field urgently need to innovate and solve. Summary of the invention

[0005] In view of this, the present invention provides a material dragging assembly and a waste material utilization mechanism having the assembly. The die punching waste material utilization mechanism of the present invention has a simple design and does not require an external auxiliary mechanism.

[0006] In order to achieve the above object, the present invention adopts the following technical solution:

[0007] A material dragging assembly is arranged in a cutting die blanking mechanism, and the cutting die blanking mechanism also includes an upper die assembly and a lower die assembly, including a spring baffle, a core shaft fixing plate, a core shaft and a spring; the spring baffle is fixed to the lower die assembly, one end of the core shaft is fixed to the core shaft fixing plate, the other end of the core shaft passes through the spring baffle and extends out of the spring baffle, the spring is arranged between the spring baffle and the core shaft fixing plate, and the core shaft fixing plate is adapted to be slidably connected to the upper die assembly.

[0008] The present invention adds a material dragging assembly to the upper die assembly and the lower die assembly, so that the core shaft can drag the blank placed in the cutting die blanking mechanism at the bottom. When the upper die assembly moves from top to bottom, the upper die assembly abuts against the core shaft fixing plate, and the core shaft fixing plate drives the core shaft to move backward. At the same time, the upper die assembly and the lower die assembly cooperate to cut and blank the blank. When the upper die assembly moves from bottom to top, the core shaft fixing plate drives the core shaft to move forward under the action of a spring and moves to the lower end of the blank. The blank is fed under the mechanical action, and the core shaft drags the blank to prevent serious waste because the blank cannot be cut and blanked when it reaches the last section because the weight of the front end is greater than the weight of the rear end.

[0009] Furthermore, the core shaft fixing plate includes a fixed section and a bevel section, the fixed section is fixed at both ends of the bevel section, the fixed section is fixedly connected to the core shaft, the bevel section is a rectangle with one corner beveled, and the cut surface is adapted for sliding connection with the upper mold assembly.

[0010] When the upper die assembly moves downward from top to bottom, the mandrel fixing plate is moved in the opposite direction by the crimping inclined surface section, so that the mandrel is separated from the material dragging position, and the cut blank can be separated smoothly.

[0011] Furthermore, it also includes a mandrel pad, which is fixed to one side of the mandrel fixing plate relative to the inclined surface of the beveled section. The mandrel pad can enhance the strength of the mandrel fixing plate to ensure that the upper mold assembly does not cause stamping damage to the mandrel fixing plate during stamping.

[0012] A waste material utilization mechanism comprises an upper mold assembly, a lower mold assembly and a material drag assembly as described above, wherein:

[0013] The cam assembly comprises an upper mold plate, an upper mold pad, an upper mold knife block, a pressure plate, a pressure spring, a positioning bolt and an upper sliding block; one end of the positioning bolt is fixed to the pressure plate, and the upper mold pad and the upper mold plate have a plurality of limiting holes, and the limiting holes correspond to the positions of the positioning bolts, and the other end of the positioning bolt passes through the upper mold pad and is slidably connected with the limiting holes; the upper mold pad is located below the upper mold plate, and the pressure spring is fixed to the pressure plate and passes through the upper mold pad and is arranged between the upper mold plate and the pressure plate; the upper mold knife block is fixedly connected to a side of the upper mold pad facing the pressure plate, and the upper mold knife block is located at the side end of the pressure plate when it moves up and down with the upper mold pad; the upper sliding block is fixedly connected to a side of the upper mold plate facing the upper mold pad; the upper sliding block is adaptively slidably connected to the core shaft fixing plate;

[0014] The lower mold assembly includes a lower mold plate, a lower mold frame, a lower mold knife block, a lower slider, a parts collection box, a guide rail, a foot pad, and a foot pad;

[0015] The guide rail is fixed on the upper surface of the foot plate and corresponds to the position of the upper die knife block, and the parts collection box is slidably connected to the guide rail; the foot is fixed on the upper surface of the foot plate and is located at the periphery of the parts collection box, the lower template is fixed on the upper part of the foot and has a parts dropping hole, and the parts dropping hole corresponds to the position of the upper die knife block, the lower slider is fixed to the side end of the parts dropping hole and corresponds to the position of the upper slider, the mandrel fixing plate is slidably connected to the lower slider, and the upper slider presses the mandrel fixing plate away from the part dropping hole when the upper die pad moves up and down; the lower mold frame is fixed on the side end of the mandrel fixing plate and is located at the upper end of the lower template, one end of the lower mold frame is fixed with the lower die knife block and the other end is provided with a blank groove, and the blank groove corresponds to the position of the part dropping hole.

[0016] The upper mold assembly moves downward: first, the pressing plate contacts the blank and the pressing spring is compressed. The upper slider moves downward and is introduced into the cavity composed of the mandrel fixing plate and the lower mold frame. The mandrel extends out to drag the blank. At this time, the spring is not stressed and is in a free state. The upper mold knife block has not yet contacted the lower mold knife block. The pressing spring continues to be compressed, the pressure increases, the pressing plate presses the blank to ensure that the blank will not slide, and the upper slider continues to move downward to the bottom dead point. The mandrel fixing plate and the mandrel pad drive the mandrel to move backward under the guidance of the lower slider, and the mandrel withdraws from the support. At this time, the spring is compressed, the upper mold knife block moves downward and forms a scissors with the lower mold knife block to cut the blank. The production of one part is completed, and the part falls into the part collection box.

[0017] The upper die assembly moves upward: the elastic force of the pressing plate disappears and returns to the initial state; the upper slider is separated from the mandrel fixing plate and the elastic force disappears, the mandrel extends out and continues to drag the material; the upper die knife block moves upward to prepare for the next shearing.

[0018] The upper die assembly continues to move downward and upward repeatedly, and finally completes the shearing of the entire blank.
