The male die is arranged on the upper die base, a male die fixing guide sleeve is arranged on the upper die base, and the male die is movably arranged in the male die fixing guide sleeve.
The technical scheme has the advantages that:
The utility model provides a forming device of an electrical contact, which is characterized in that a male die, a female die and a forming groove are designed, and the workpiece is deformed according to the shape of the forming groove by utilizing the downward movement of the male die, so that the workpiece is processed to a specified shape; meanwhile, processes such as heating and the like are not needed, and the production cost can be reduced.
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are a part of the embodiments of the present invention, not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present invention without any creative effort, shall fall within the protection scope of the present invention.
Drawings
FIG. 1 is a schematic structural diagram of embodiment 1 of the present invention;
Fig. 2 is a schematic structural view of the male die and the male die fixing guide sleeve in the present novel embodiment 1.
Detailed Description
Example 1
The forming equipment of the electrical contact comprises an upper die holder 1, a lower die holder 2, a male die 3 and a female die 4; a forming groove 40 is arranged in the female die 4, and the forming groove 40 is a pre-designed forming groove according to the appearance requirement of a workpiece; the male die 3 can be vertically moved and arranged right above the forming groove 40, so that the female die forming groove 40 can be filled under the extrusion of the male die 3 by utilizing the downward pressing of the male die 3 and the plasticity of the red copper material, and then a workpiece is formed.
specifically, a first die sleeve 41 and a second die sleeve 42 are arranged around the periphery of the female die 4, the first die sleeve 41 is sleeved on the female die, and the second die sleeve 42 is sleeved on the first die sleeve 41; through such setting, can avoid the die impaired at the extrusion in-process of terrace die, adopt the reinforced mode of multilayer die case moreover, also can promote the bearing capacity of die.
More specifically, the first and second chase blocks 41 and 42 have a trapezoidal shape in their outer shape.
Specifically, the bottom of the lower die holder 2 is provided with an ejection assembly, the ejection assembly comprises an ejector rod 5, the bottom of the ejector rod 5 is connected with an ejector block 6, and two sides of the ejector block 6 are provided with lower die pads 7; a through hole 43 is formed in the bottom of the female die 4, the through hole 43 is located in the bottom of the forming groove 40, the inner diameter of the through hole 43 is smaller than the cross sectional area of the bottom of the forming groove 40, and the ejector rod 5 is arranged at the bottom of the through hole 43; through such setting, can utilize the work piece after the shaping that shifts up in messenger's shaping groove to break away from the shaping groove of ejector pin after processing is accomplished, be convenient for take off the material and collect.
More specifically, the diameter of the ejector pin 5 is smaller than the inner diameter of the through hole 43; through such setting, the action of ejector pin can be convenient for.
More specifically, the axis of the through hole 43 and the axis of the forming groove 40 coincide with each other; through such setting, can ensure that when the liftout to the work piece bottom application of force even, avoid the work piece to cause the destruction.
Specifically, a positioning plate 8 is arranged at the top of the female die 4, a pressing plate 9 is arranged on the positioning plate 8, openings are arranged on the pressing plate 9 and the positioning plate 8 corresponding to the forming grooves 40, and the cross-sectional area of each opening is larger than that of the male die 3.
More specifically, the pressure plate 9 is fixed on the lower die base 2 through hexagon socket head cap screws 90.
Specifically, the upper die holder 1 is fixed above the lower die holder 2, a male die fixing guide sleeve 10 is arranged at a position of the upper die holder 1 relative to the forming groove 40, the bottom of the male die fixing guide sleeve 10 is contacted with the bottom of the forming groove 40, and the male die 3 is arranged in the male die fixing guide sleeve 10; through the arrangement, the male die 3 can be limited by the male die fixing guide sleeve 10, so that the male die 3 can only move on the same straight line, and the phenomenon that the workpiece is unevenly stressed and damaged due to vibration is avoided.
In addition, in the present embodiment, the driving of the top block and the punch may be performed by using a cylinder as long as the top block and the punch are ensured to reciprocate in one direction.
