Description
Technical field
The utility model belongs to diel and manufactures field, is particularly with the punching die frame of flexible discharging ring.
Background technology
Crooked part is one of part that during Modern Industry Products, automobile, electrical equipment, instrument and instrument manufacture, quantity is maximum.Require various different bending method according to the difference of bool, the bending such as carried out on bender, bending roll machine, stretch benders, roll bending, stretch bending etc., the most frequently used is utilize general stamping machine to bend on punch die.The core of punch die is mould bases, can be described as the skeleton of whole set of die, mould bases in use can coordinate guiding, power set and fastener to form complete diel, in Punching Process, occur some problems toward the reason that can should be mould bases, the original paper of such as processed mistake easily or can not removal smoothly.Operator could allow feed system work on after stamping parts must being taken out, virtually reduce operating efficiency, if moreover product after punching press can not take out in time, be easy to cause deformation of products, the inferior rate of product is high, also brings hidden danger to safety in production simultaneously.
Utility model content
The purpose of this utility model is a kind of punching die frame solving drift adhesion workpiece and cause the demoulding freely not put forward.
To achieve these goals, the punching die frame of the flexible discharging ring of the band that the utility model provides, comprises punch, punch fixed block, die, die fixed block, matched moulds platform and workpiece fore-set; Described punch is fixed in the geometric center of punch fixed block; described die is connected on die fixed block by cushion block; described matched moulds platform to be pressed on die and to be fixedly connected with die fixed block by bolt; workpiece fore-set and die are slidably connected; wherein; be connected with discharging ring by spring below described punch fixed block, discharging ring outer wall arranges one deck elastic caoutchouc, and described discharging ring and punch are slidably matched.
The punching die frame of the flexible discharging ring of band that this programme is introduced when in use, coordinate other annexes of punch die, workpiece is put into above die, punch is driven to move downward by machining spindle, in the first punching course of punch, workpiece can form required structure according to the contour shape of punch and die, after punching press completes, because workpiece is in bending, also there is larger deformation power in workpiece, if stamping press slightly conference causes workpiece to be attached on punch, if stamping press is less, workpiece can be caused to support in die, but have the difference of structure due to workpiece itself, cause the situation that stamping press reaches just right.Now if be clipped on punch, because discharging ring meeting and punch synchronously decline, discharging ring bottom can prop up workpiece, and the sidewall of discharging ring can be stuck in matched moulds platform simultaneously, and when punch moves upward time, workpiece can be deviate from from punch under discharging ring stops.If workpiece support is on die, by workpiece fore-set, workpiece is ejected; Whole process completely avoid the situation that snap gauge appears in workpiece, improves the working (machining) efficiency of workpiece.
As preferred scheme, described punch fixed block and discharging ring circumference are provided with adjusting bolt, and adjusting bolt is slidably connected by counterbore and punch fixed block, and adjusting bolt is threaded with discharging ring; Because in punching course, discharging ring there will be distortion, the distance changing discharging ring and punch fixed block by adjusting bolt regulates the versatility of discharging ring.
As preferred scheme, between described discharging ring and punch fixed block, be connected with packing ring.Packing ring pad, between punch fixed block and discharging ring, adds the bonding strength between them.
As preferred scheme, described workpiece fore-set is provided with stroke platform, die fixed block is provided with the formation hole of coupling stroke platform.Due to fore-set stretch out be moment impulse force, by the restriction of stroke platform, slow down the damage of workpiece fore-set.
Finally, be provided with discharging tracheae in described workpiece fore-set, pass into gases at high pressure in discharge process discharging tracheae, object is that another benefit is to blow away the impurity in die the workpiece spring of support in die.
Accompanying drawing explanation
Fig. 1 is the structural representation of the punching die frame being with flexible discharging ring.
Reference numeral is enumerated: punch 1, adjusting bolt 2, punch fixed block 3, packing ring 4, workpiece 5, die 6, die fixed block 7, spring 8, discharging ring 9, workpiece fore-set 10, stroke platform 11, discharging tracheae 12, matched moulds platform 13.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated;
As shown in Figure 1, with the punching die frame of flexible discharging ring, comprise punch 1, punch fixed block 3, die 6, die fixed block 7, matched moulds platform 13 and workpiece fore-set 10; Punch 1 is fixed in the geometric center of punch fixed block 3, die 6 is connected on die fixed block 7 by cushion block, matched moulds platform 13 to be pressed on die 6 and to be fixedly connected with die fixed block 7 by bolt, workpiece fore-set 10 and die 6 are slidably connected, connect below punch fixed block 3 and be connected with discharging ring 9 by spring 8, discharging ring 9 outer wall arranges one deck elastic caoutchouc, and discharging ring 9 and punch 1 are slidably matched.
The punching die frame of the flexible discharging ring of band that this programme is introduced when in use, coordinate other annexes of punch die, workpiece 5 is put into above die 6, punch 1 is driven to move downward by machining spindle, in the first punching course of punch 1, workpiece 5 can form required structure according to the contour shape of punch 1 and die 6, after punching press completes, because workpiece 5 is in bending, also there is larger deformation power in workpiece 5, if stamping press slightly conference causes workpiece to be attached on punch, if stamping press is less, workpiece can be caused to support in die, but have the difference of structure due to workpiece itself, cause the situation that stamping press reaches just right.Now if be clipped on punch, because discharging ring meeting and punch synchronously decline, discharging ring bottom can prop up workpiece, and the sidewall of discharging ring can be stuck in matched moulds platform simultaneously, and when punch moves upward time, workpiece can be deviate from from punch under discharging ring stops.If workpiece support is on die, by workpiece fore-set, workpiece is ejected; Whole process completely avoid the situation that snap gauge appears in workpiece, improves the working (machining) efficiency of workpiece.
Punch fixed block and discharging ring circumference are provided with adjusting bolt 2, and adjusting bolt 2 is slidably connected by counterbore and punch fixed block 3, and adjusting bolt 2 is threaded with discharging ring 9; Because in punching course, discharging ring there will be distortion, the distance changing discharging ring and punch fixed block by adjusting bolt regulates the versatility of discharging ring.
Packing ring 4 is connected with between discharging ring and punch fixed block.Packing ring 4 pads between punch fixed block 3 and discharging ring 9, adds the bonding strength between them.
Workpiece fore-set 10 is provided with stroke platform 11, die fixed block is provided with the formation hole of coupling stroke platform.Due to fore-set stretch out be moment impulse force, by the restriction of stroke platform 11, slow down the damage of workpiece fore-set.
Be provided with discharging tracheae 12 in workpiece fore-set 10, pass into gases at high pressure in discharge process discharging tracheae 12, object is that another benefit is to blow away the impurity in die the workpiece spring of support in die.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite not departing from the utility model structure; some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
