Description
Technical field
The present invention relates to flat pieces extrusion technique field, being specifically related to a kind of mould bases for installing flat pieces extrusion die.
Background technology
The thickness of the extrusion of flat pattern is much smaller than its diameter, and its extrusion process is poor, extruding force and more difficult the control of shaping difficulty.With the flat pieces of shallow bellmouth, because the thickness bottom bellmouth is less, and the conical surface is to the inhibition of metal fluidity, therefore usually adopt twice extruded, make coniform hole deepen gradually time shaping, to reduce extruding force.At present, two molds that shallow bellmouth flat pieces is extruded are all be arranged separately on respective mould bases, and use two cover mould bases, not only cost is high, and floor space is large.
Summary of the invention
The invention is intended to provide a kind of mould bases for installing flat pieces extrusion die that can be two molds and share.
The mould bases for installing flat pieces extrusion die in this programme, comprise die holder and the second nut, the top of die holder has the first groove, the periphery of the first groove cell wall is provided with external screw thread, second its thread is connected to the top of die holder, first groove and the second nut form die mounting groove jointly, die holder is provided with the first push rod, first push rod can extend in mounting groove, be positioned at directly over die holder and be provided with die shank, the bottom of die shank has the second groove, the periphery of the second groove cell wall is provided with external screw thread, the lower thread of die shank is connected with the first nut, second groove and the first nut form punch mounting groove jointly.
Beneficial effect of the present invention is as follows: the second nut and the first groove are for installing the die of bottom, first nut and the second groove for installing the punch on top, therefore, during use, only need to change die, punch and backing-out punch, two molds for extruding flat pieces just can be installed respectively.The location of concrete punch and die adopts the first special nut and the second nut, this locate mode respectively, when changing, easy to operate.
Further, the bottom of die holder has the 3rd groove, the lower surface of die holder is provided with gland, gland covers on the 3rd groove, be provided with jacking block in 3rd groove, the top of jacking block and the lower surface of the first push rod offset, and the bottom of jacking block is fixed with the second push rod, gland has through hole, and the second push rod is through described through hole.By the transfer mode ejected step by step of the second push rod and the first push rod, avoid producing larger impulsive force to die, eject more stable.
Further, be positioned at center at the bottom land of the first groove and be provided with erection column, erection column is provided with adjusting pad.By taking out or put into the mode of adjusting pad, the groove depth of adjustable first groove, thus the die of different size can be installed.
Further, in the second groove, be provided with fixed cover, the lower surface of described fixed cover and the inner face of the second nut offset.Fixed cover is for strengthening the intensity of the first nut end face, more stable during installation punch.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: die shank 1, cushion block 2, fixed cover 3, first nut 4, second nut 5, lining 6, fixed cover 7, adjusting pad 8, packing ring 9, first push rod 10, die holder 11, gland 12, second push rod 13.
Embodiment is substantially as shown in Figure 1: the present embodiment is for installing the mould bases of flat pieces extrusion die, the top of die shank is stepped, the bottom of die shank has the second groove, the periphery of the second groove cell wall is provided with external screw thread, the lower thread of die shank is connected with the first nut, and the second groove and the first nut form punch mounting groove jointly.Be provided with the fixed cover of cushion block and ring-type in second groove, the bottom land of cushion block side and the second groove offsets, and the upper surface of cushion block opposite side and fixed cover offsets, the lower surface of fixed cover with offset with the inner face of the second nut.
Die holder is positioned at immediately below die shank, the top of die holder has the first groove, the periphery of the first groove cell wall is provided with external screw thread, second its thread is connected to the top of die holder, first groove and the second nut form die mounting groove jointly, and the lining be close to cell wall being provided with ring-type in the first groove, is positioned at center at the bottom land of the first groove and is provided with erection column, erection column is provided with adjusting pad, and the edge of adjusting pad and the inner circle of lining offset.
Die holder is provided with the first push rod, first push rod can extend in mounting groove, the bottom of die holder has the 3rd groove, the lower surface of die holder is provided with gland, gland covers on the 3rd groove, is provided with jacking block in the 3rd groove, and the bottom of jacking block is fixed with the second push rod, gland has through hole, and the second push rod is through described through hole.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
