Abstract
The utility model relates to an upsetting die applied to stripping-free screws. The upsetting die is characterized in that: the main body is a cylindrical tubby main die sleeve, wherein an opening and closing die cover plate is fixedly arranged on the upper part of the main die sleeve through a fastener; three opening and closing dies, an opening and closing die sleeve, a main die, a cushioning block and a die locking cover arranged at the bottom of the main die sleeve are sequentially arranged in the main die sleeve from top to bottom; three opening and closing die opening and closing pins are arranged on the opening and closing die sleeve; the three opening and closing dies do opening and closing movement through the opening and closing pins; a top rod is arranged in the cushioning block; and a spring is arranged between the cushioning block and the die locking cover. Through the design of an upsetting tool clamp, 60 to 70 products can be produced every minute by using automation equipment, and the yield is 200 to 300 times that of the products produced by turning through a machine tool, so the production efficiency is greatly improved, the consistency of the size of the products is ensured, the strong cutting at the combination place of a head rod is avoided, and the mechanical performance strength of the products is improved.
Description
Technical field
The utility model relates to a kind of frock clamp, especially relates to a kind of heading die of not deviating from screw.
Background technology
Not deviating from screw is one of securing member of using always in the existing market; Its characteristics are the intermediate bar footpath product thinner than two, and what main technique adopted in process of production is to use the material near diameter before the screw thread processing to carry out processing thin rod part branch, thread-rolling screw again through the mode of cutting behind the cold-heading head; From above-mentioned technology, can find out; Main processing intensity is processed with the mode on lathe one folder one top at cutting process, and the product precision receives the influence of people and cutter bigger; And the head rod junction has suffered strong cutting, and the metal streamline fracture influences the product mechanical properties strength.
Summary of the invention
The utility model technical problem to be solved provides a kind of clamping and fixes, avoids adopting cutting way to influence the heading die of its metal streamline and product mechanical properties strength.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of heading die; Main body is a cylinder tubbiness master die sleeve; Said main die sleeve top fixedly mounts a folding die cap plate through securing member, and main die sleeve inside is disposed with three folding moulds, folding die sleeve, main mould, cushion block from top to down and is arranged on the locked mode lid of main die sleeve inside bottom; Said folding die sleeve is provided with three folding moulds and opens and close pin, and three folding moulds closing pin and do the opening and closing motion through opening; Said cushion block inside is provided with a push rod, is provided with spring between cushion block and the locked mode lid.
The tightness that is connected of master's die sleeve and cover plate when guaranteeing cold forging, said securing member is a bolt.
In order to adopt the backward extrusion mode, the top of said push rod extends in the main mould, and the bottom of push rod extends to the outside of main die sleeve.
After adopting said structure, be characterized in: three folding moulds and folding die sleeve tapering when stressed closely cooperate, and when product moves back mould, release product utilization with push rod and open that closing pins struts three folding moulds; Can release smoothly after the cold-heading and be extruded workpiece, accomplish the automation jumping-up, the design through the jumping-up frock clamp utilizes automation equipment; Per minute production capacity can reach 60～70; Be 200～300 times that lathe turning is processed, improve greatly and come production efficiency, also guaranteed the uniformity of product size; Avoid the strong cutting of head rod junction, improved the product mechanical properties strength.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the internal view of the utility model.
Among the figure: 1, folding die cap plate 2, three folding moulds 3, folding die sleeve 4, three folding moulds are opened and are closed pin 5, main die sleeve 6, main mould 7, cushion block 8, spring 9, locked mode lid 10, securing member 11, push rod.
The specific embodiment
A kind of heading die that is applied to deviate from screw shown in Figure 1; Main body is a cylinder tubbiness master die sleeve 5; Said main die sleeve 5 tops are through securing member 10 fixed installation one folding die cap plate 1, and main die sleeve 5 inside are disposed with three folding moulds 2, folding die sleeve 3, main mould 6, cushion block 7 from top to down and are arranged on the locked mode lid 9 of main die sleeve 5 inside bottom; Said folding die sleeve 3 is provided with three folding moulds and opens and close pin 4, three folding moulds 2 and close pin 4 and do the opening and closing motion through opening; Said cushion block 7 inside are provided with a push rod 11, are provided with spring 8 between cushion block 7 and the locked mode lid 9.Said securing member 10 is a bolt, the tightness that is connected of master's die sleeve 5 and main die sleeve cover plate 1 when having guaranteed cold-heading; The top of said push rod 11 extends in the main mould 6; The bottom of push rod 11 extends to the outside of main die sleeve 5; Said three folding moulds 2 closely cooperate with folding die sleeve 3 tapering when stressed; When product moves back mould, release product utilizations and open and close pin 4 and strut three folding moulds 2, adopt the backward extrusion mode, and after cold-heading, can release smoothly and be extruded workpiece with push rod 11.
On cold-heading equipment, clash into folding mould 2 through punch die; The elasticity of utilizing spring 8 closely cooperates three folding moulds 2 and folding die sleeve 3 taperings and drives main mould 6, cushion block 7 moves downward; Utilize push rod 11 that material is carried out backward extrusion, make workpiece moulding in main mould 6 reach the required size requirement, eject workpiece through push rod 11 again and utilize the folding mould to open simultaneously to close pin 4 that three folding moulds were opened in 2 minutes; Workpiece ejects smoothly, accomplishes one-shot forming.
Design through the jumping-up frock clamp utilizes automation equipment; Per minute production capacity can reach 60～70; Be 200～300 times that lathe turning is processed, improved production efficiency greatly, also guaranteed the uniformity of product size; Avoid the strong cutting of head rod junction, improved the product mechanical properties strength.
