Abstract

The utility model discloses an upper cutter of an upper die of a pressing machine. The upper cutter comprises a cuter body, a substrate is arranged at the left side of the cutter body for fixing the cutter body at the lower side of a long arm, the left surface of the substrate is provided with more than two mounting holes, the cutter body is provided with a longitudinal guiding hole penetrating through the upper surface and the lower surface of the cutter body, the guiding hole is matched with a thimble, the lower part of the cutter body is provided with a notch matched with the forming end of an iron drill, and the notch corresponds to the guiding hole. The matching precision of the guiding hole and the thimble is higher so as to guide a punch-pin better.

Description

A kind of patrix upper cutter of press-connection machine

Technical field

The utility model relates to the patrix upper cutter of the press-connection machine that a kind of riveted wire rod uses.

Background technology

Press-connection machine (being also referred to as the copper strips machine) is a kind of machine in order to the riveted wire rod, the long-armed lower end of its patrix is fixed with upper cutter, having on the upper cutter can be for inserting towards pin and can be along its vertical guide groove that slides up and down, long-armed drive upper cutter is descending, cooperate with the lower cutter that is fixed on the upper bolster bottom, to cut off from the copper strips that the lower cutter charging aperture stretches out, follow and the anvil cooperation, after the guide groove bottom tentatively is shaped to the copper strips that cuts off " U " type structure of handstand and pushes anvil open, upper cutter stops descending, being about to " U " type copper strips towards pin under the guide groove of the drive lower edge of galianconism this moment releases from the guide groove bottom, and push bed die to, at last copper strips is pressed on the crimping face of bed die and forms terminal, copper strips is curled and the riveted wire rod on the bed die crimping position placed side by side.Obviously, can upper cutter cut off and first one-step forming copper strips smoothly, and successfully guide towards pin, directly influences the terminal Forming Quality, and then influence the resistance to tension between the wire rod.

The patrix upper cutter of the press-connection machine of prior art as shown in Figure 1, comprise left cutter rail 100 and right cutter rail 200, respectively form groove on left side cutter rail 100 and right cutter rail 200 face in opposite directions, a left side cutter rail 100 and right cutter rail 200 are installed to long-armed 400 downside side by side by certain distance, then are formed for guiding the guide groove towards pin 300 upper and lower slips between the left and right cutter rail 100,200.Long-armed 400 can be under the driving of drive unit, the drive upper cutter is descending, cooperate with lower cutter and anvil respectively, finish the cut-out and the preliminary shaping work of copper strips, galianconism 500 can drive under the driving of toggle 600 towards pin 300 along guide groove and glide, and the copper strips of first one-step forming is released and finally is pressed on the crimping face of bed die from guide groove.But, the patrix upper cutter structure of this press-connection machine still has some deficits, as: the difficult control of the installation accuracy of left cutter rail 100 and right cutter rail 200, the back is installed occurs the excessive or too small situation of distance between the left and right two cutter rails 100,200 easily, and then influence is towards the quality of fit of pin 300 with guide groove, distance is excessive, then makes the pin 300 that dashes in the guide groove occur vacillating now to the left, now to the right, and finally influences the Forming Quality of terminal; And distance is too small, can't insert guide groove or aggravation towards the wearing and tearing of pin 300 towards 300 on pin.

Summary of the invention

The purpose of this utility model is to provide a kind of patrix upper cutter of press-connection machine, its with towards the quality of fit height of pin, the pin that can liquidate better leads.

The patrix upper cutter of press-connection machine described in the utility model, comprise a cutting knife body, the cutter body left side is useful on the substrate that cutter body is fixed to long-armed downside, there is plural installing hole the left surface of substrate, the longitudinal guide hole of running through its upper and lower surface is arranged on the cutter body, this bullport and thimble are complementary, the breach that corresponding bullport position, cutter body bottom has the forming ends with anvil to be complementary.

The patrix upper cutter of press-connection machine described in the utility model, the upper and lower surface of the cutter body of running through is arranged, and with the bullport that is complementary towards pin, lead by the bullport pin that liquidates, can make handstand " U " the type copper strips that will tentatively be molded over the breach downside towards pin push bed die to, at last copper strips is pressed on the crimping face of bed die and forms terminal, copper strips is curled and the riveted wire rod on the bed die crimping position placed side by side, this cutter body is an overall structure, as long as process the bullport that the meets dimension precision requirement pin channeling conduct that can successfully liquidate thereon.The elder generation that adopts with prior art processes left and right two cutter rails respectively, left and right two cutter rails being installed at a certain distance side by side long-armed downside compares to be formed for guiding towards the mode of the guide groove of pin again, bullport of the present utility model is with higher towards the quality of fit of pin, and its pin that can liquidate better leads.

Embodiment

Shown in Fig. 2 to 4, the patrix upper cutter of press-connection machine described in the utility model, comprise a cutting knife body 1, cutter body 1 left side is useful on the substrate 2 that cutter body 1 is fixed to long-armed 4 downsides, there is more than two the installing hole 21 in order to mounting screw the left surface of substrate 2, cutter body 1 can be fixed on long-armed 4 downsides by screw, have on the cutter body 1 and run through on it, following longitudinal guide hole 11, thimble 3 is complementary with bullport 11 and can slides up and down along bullport 11, the breach 12 that corresponding bullport 11 positions, cutter body 1 bottom have the forming ends 71 with anvil 7 to be complementary.During work, it is descending to drive upper cutter under the driving of long-armed 4 actuating units in prior art (as toggle), cooperate with the lower cutter 6 that is fixed on the upper bolster bottom, to cut off from the copper strips that lower cutter 6 charging apertures 61 stretch out, then and forming ends 71 cooperations of anvil 7, after breach 12 places tentatively are shaped to the copper strips that cuts off " U " type structure of handstand and push anvil 7 open, upper cutter stops descending, this moment is descending at the drive lower edge of galianconism 5 bullport 11 towards pin 3, " U " type copper strips that stands upside down is released from breach 12, and push bed die to, at last copper strips is pressed on the crimping face of bed die, form terminal, copper strips is curled and the riveted wire rod on the bed die crimping position placed side by side.

As Fig. 2, shown in Figure 4, there is vertical raised line 22 left surface of substrate 2, this vertical raised line 22 mates with the longitudinal spacing groove 41 of long-armed 4 downsides, when installing cutting knife, earlier raised line 22 correspondences are snapped in the stopper slot 41, by screw substrate 2 is fixedly linked with long-armed 4 again, makes the installation of upper cutter more convenient, and make the body after the installation keep vertical state.
