Abstract
The invention provides a punching die. The punching die comprises a male die and a female die. The female die is in a cylinder shape. An inner cavity of the female die is a punch travel cavity. The size of the male die is matched with the size of the inner cavity of the female die. The upper end face of the female die is provided with a raw material containing table. A feed mechanism is arranged on the side face of the upper end face of the female die. The feed mechanism and the containing table are horizontally arranged. A shearing face of the containing table on the upper end face of the female die is in a bent face shape. The punching die further comprises a sliding mechanism which is detachably connected with the bottom of the female die. The punching die has the advantages that shearing cotton yarn of the female die is designed into the bent face shape, the aims of conducting material force bearing step by step and conducting punching part by part are achieved, and the requirement for greatly reducing the machine tool tonnage is achieved; cost is saved, the machine tool vibration is not large, and noise is reduced; the die vibration is small, no abnormal sound is generated, the service life of the male die and the female die is prolonged, the quality of the die is improved, and manpower and material resources are reduced.
Description
Technical field
The present invention relates to mould applications, particularly relate to diel.
Background technology
Diel is in Cold Press Working, material (metal or nonmetal) is processed into a kind of special process equipment of part (or semi-finished product), is called cold punching die (being commonly called as cold-punching mould).Punching press is at room temperature, utilizes the mould be arranged on forcing press to apply pressure to material, makes it produce separation or plastic deformation, thus obtains a kind of pressure processing method of required part.
Diel is the requisite technological equipment of punching production, is technology-intensive product.The quality of stamping parts, production efficiency and production cost etc., have direct relation with Design of Dies and manufacture.
Current most diel is a direct a kind of mould expecting to thrust, comprise die and punch, the upper surface of die is product mounting table, during punching press, by the impingement distance power of punch downward moment, because each position of the die upper surface of existing mold is all in same level, when punching press, the plane of thrust place that needs of institute on material is simultaneously stressed, so, too large to the tonnage demand of punch press, punch press vibrations are simultaneously too large, and noise is large, has a strong impact on the sense of hearing of workman, to healthy unfavorable, also easily cause workman's fatigue strength.The vibrations of this outer mold are too large, and have abnormal sound, easily cause punch, biting of die, shakes bad, reduces the life-span of mould.
Summary of the invention
In order to solve the problems of the prior art, the invention provides a kind of diel.
The invention provides a kind of diel, comprise punch and die, described die is cylindric, and die inner chamber is punch travel chamber, punch and die cavity shape matching size, the upper surface of die is raw material mounting table, side, die upper surface is provided with feed mechanism, and feed mechanism and mounting table are horizontally disposed with, and the shear surface at mounting table place, die upper surface becomes curved, this diel also comprises slide mechanism, and described slide mechanism and described female bottom are removable connection.
As a further improvement on the present invention, described slide mechanism comprises loading plate, pulley, band, and described pulley is installed and below described loading plate, described band is connected with described loading plate, described female bottom is provided with grab, and described band is for bundling the grab of described die.
As a further improvement on the present invention, described shear surface longitudinal section becomes corrugated.
As a further improvement on the present invention, the difference in height of described corrugated shear surface is 5-6mm.
As a further improvement on the present invention, be provided with product ejecting mechanism in described die, described ejecting mechanism comprises top board, cylinder and is arranged on the roller of roof perimeter, and described roller contacts with die inwall.
As a further improvement on the present invention, described roof perimeter is provided with short slot roller and is arranged in short slot.
The invention has the beneficial effects as follows: the shearing cotton yarn of die is designed to curved by diel of the present invention, object is carried out step by step by stressed for material, thrusting of Part, and advantage greatly reduces the requirement to lathe tonnage.Saved cost, and lathe vibrations are also little, noise reduces.Mould vibrations are less, have no abnormal sound, and extend punch die service life, improve the quality of mould, reduce manpower and materials.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is combination product of the present invention schematic diagram when thrusting.
Detailed description of the invention
As shown in Figure 1, 2, the invention discloses a kind of diel, comprise punch 1 and die 2, described die 2 is cylindric, and die 2 inner chamber is punch 1 stroke chamber 2.1, punch 1 and die 2 cavity shape matching size, the upper surface of die 2 is raw material mounting table, side, die 2 upper surface is provided with feed mechanism, and feed mechanism and mounting table are horizontally disposed with, the shear surface 2.2 one-tenth curved at mounting table place, die 2 upper surface.
Described shear surface 2.2 longitudinal section becomes corrugated.The shear surface of existing diel upper cavity die is a plane, and after above material is placed on, during punching press, all faces of material are all stressed, all please thrust simultaneously, just high to the requirement of punch press like this.And shear surface 2.2 of the present invention is designed to curved, object says that each of material is stressed separately exactly, that is during punch 1 impact material, only have material component face and shear surface 2.2, after thrusting this part, remaining part continues and the shear surface 2.2 of position slightly lower part contacts, until all thrust.
This diel also comprises slide mechanism, and described slide mechanism is connected for removable with bottom described die 2.Its specific embodiment is: described slide mechanism comprises loading plate, pulley, band, and described pulley is installed and below described loading plate, described band is connected with described loading plate, and described female bottom is provided with grab, and described band is for bundling the grab of described die.So, grab is bundled by band, not only easy to operate, and be connected firmly, band not easily gets loose; And when slide mechanism will be realized to be separated with die 2, band is untied, very convenient; Can the movement of very convenient die 2 by this slide mechanism, strengthen its practicality.
The difference in height of described corrugated shear surface 2.2 is 5-6mm, described shear surface 2.2 one-tenth curved, and longitudinal section looks over and has height and have the end, and the distance of peak and minimum point is 5-6mm.
Be provided with product ejecting mechanism in described die 2, described ejecting mechanism comprises top board, cylinder and is arranged on the roller of roof perimeter, and described roller contacts with die 2 inwall.
Described roof perimeter is provided with short slot roller and is arranged in short slot.
A kind of diel of the present invention, the shearing cotton yarn of die is designed to curved surface dress, object is carried out step by step by stressed for material, and thrusting of part, advantage greatly reduces the requirement to lathe tonnage.Saved cost, and lathe vibrations are also little, noise reduces.Mould vibrations are less, have no abnormal sound, and extend punch die service life, improve the quality of mould, reduce manpower and materials.
Above content is in conjunction with concrete preferred embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, some simple deduction or replace can also be made, all should be considered as belonging to protection scope of the present invention.
