Abstract
The utility model discloses a kind of round pin and rush flat hole tool, it comprises lower mould bottom plate, counterdie, upper baffle plate, patrix and cylinder, counterdie is removably disposed in described lower mould bottom plate, patrix is detachably arranged on the bottom of described upper baffle plate, cylinder bottom is fixedly installed in lower mould bottom plate, cylinder top is removably connected with described upper baffle plate, for driving the on-off action of described patrix, correspondence position on described patrix and described counterdie all has the round pin portion holding round pin, and patrix has the square hole passed through for drill bit.Rush flat punch die with existing round pin to compare, cylinder is arranged on the both sides of counterdie, situation stressed when holing from round pin, round pin is overall stressed more even, ensure that the dimensional accuracy on round pin square hole, test in addition according in fact industry, the round pin of the preshoot φ 36mm size of improvements needs the round steel of use φ 40mm, and by φ 38 round steel just energy product quality after using improvement, saved certain cost.
Description
Technical field
The utility model relates to a kind of heat and rushes frock technical field, particularly relates to one and is used in rolling stock connection round pin and rushes flat hole tool.
Background technology
At present, the flat hole of traditional round pin adopts artificial screw-threaded coupling clamping round pin, flat hole is gone out by punch press, bending easily appears in the round pin bar portion processed, quality and efficiency are all lower, also the processing mold for this workpiece is had in prior art, as Chinese utility model patent, notification number: CN 202591364 U, the day for announcing: 2012.12.12, it adopts knife holder mechanism, clamp system and cylinder have cooperatively interacted the work of round pin punching, by offsetting the expansive force of knife holder mechanism when stamping-out round pin by horizontal backstop, keep the indeformable or deflection of round pin little, because horizontal backstop is only arranged on side, therefore the deformation quantity of round pin side can be prevented when carrying out stamping-out, but consider from the deformation quantity of entirety, the mould of this utility model still can not solve the deformation quantity of round pin entirety, also the dimensional accuracy of round pin entirety cannot just be ensured, therefore, there is provided a kind of and can ensure that the round pin of round pin overall dimensional accuracy rushes flat hole tool and has very important significance.
Utility model content
The utility model cannot ensure the technical problem of overall dimensional accuracy in order to the round pin punching solving prior art existence, provides a kind of and can ensure that the round pin of round pin overall dimensional accuracy rushes flat hole tool.
For achieving the above object, the technical scheme that the utility model adopts is as follows:
A kind of round pin rushes flat hole tool, it comprises lower mould bottom plate, counterdie, upper baffle plate, patrix and cylinder, described counterdie is removably disposed in described lower mould bottom plate, described patrix is detachably arranged on the bottom of described upper baffle plate, described cylinder bottom is fixedly installed in described lower mould bottom plate, described cylinder top is removably connected with described upper baffle plate, for driving the on-off action of described patrix, correspondence position on described patrix and described counterdie all has the round pin portion holding round pin, and described patrix has the square hole passed through for drill bit.
Further, the rear portion of described counterdie is removably provided with an ejector retainner plate, the position that described ejector retainner plate is corresponding with described round pin portion is provided with thimble bolt, described thimble bolt is provided with hold-down nut, described thimble bolt and described hold-down nut acting in conjunction are for locating described round pin.
A kind of round pin that the utility model provides rushes flat hole tool, rush flat punch die with existing round pin to compare, cylinder is arranged on the both sides of counterdie, situation stressed when holing from round pin, round pin is overall stressed more even, ensure that the dimensional accuracy on round pin square hole, test according in fact industry in addition, the round pin of the preshoot φ 36mm size of improvement needs the round steel using φ 40mm, and by φ 38 round steel just energy product quality after using improvement, has saved certain cost.

Fig. 2 is that a kind of round pin of the utility model rushes flat hole tool top view;
In figure: 1-lower mould bottom plate; 2-counterdie; The upper baffle plate of 3-; 4-patrix; 5-ejector retainner plate; 51-thimble bolt; 6-square hole; 7-cylinder; 8-round pin portion.
Detailed description of the invention
As shown in Figure 1-2, a kind of round pin of the present utility model rushes flat hole tool, it comprises lower mould bottom plate 1, counterdie 2, upper baffle plate 3, patrix 4 and cylinder 7, counterdie 2 is removably disposed in lower mould bottom plate 1, patrix 4 is detachably arranged on the bottom of baffle plate 3, cylinder 7 bottom is fixedly installed in lower mould bottom plate 1, cylinder 7 top is removably connected with upper baffle plate 3, for driving the on-off action of patrix 4, correspondence position on patrix and counterdie all has the round pin portion 8 holding round pin, patrix, counterdie all has the square hole 6 passed through for drill bit, the rear portion of counterdie is removably provided with an ejector retainner plate 5, the position that ejector retainner plate 5 is corresponding with round pin portion 8 is provided with thimble bolt, thimble bolt is provided with hold-down nut, described thimble bolt and described hold-down nut acting in conjunction are for locating described round pin.
During use, this frock is placed on the workbench of punch press, cylinder operation bar is also arranged on the correct position of punch press simultaneously, before frock work, first whether checkout facility running is normal, and whether lubrication, circuit etc. have exception, if all normally, proceed as follows: according to round pin figure paper size, adjustment thimble bolt, then steps up hold-down nut; During frock work, first press lower cylinder and separate key, patrix is separated with counterdie, then will the round pin bar of punching put in pin hole, and when bar one end contacts thimble bolt, press lower cylinder and close key, patrix and counterdie are closed, and round pin bar is fixed firmly by patrix and counterdie; Press the punching press key of punch press, drill bit goes out square hole through the square hole of patrix by round pin bar, and punching press completes, and presses lower cylinder and separates key, and take out the bar that punching completes, punching completes, and circulates and so forth.
Consider actual application, the effect of ejector retainner plate and thimble bolt is conveniently for the location of round pin bar with carry out punching operation for different round pin bars, adjustable along with thimble bolt and hold-down nut, the square hole position of round pin bar i.e. adjustable, when needs punching, when patrix and counterdie just can close to during thimble nut, because play the positioning action to round pin bar by the end thereof contacts of round pin bar.
Protection domain of the present utility model is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
