Description

The screw forming machine of tool sensing punch die pressure

Technical field

The utility model is about a kind of screw forming machine design, is meant a kind of screw forming machine of tool sensing punch die pressure especially.

Background technology

Consult Fig. 1, Fig. 2, known screw forming machine 1 includes a board 11, one is located on the board 11 and the feed arrangement 12, of importing blank 2 is in regular turn accepted the module 13 of feed arrangement 12 input blanks 2, and at least one blank on the module 13 2 is given stamping forming die set 14; Wherein, this module 13 has a die holder 131 that the blank 2 of this feed arrangement 12 can be given clamping location at least; In addition, die set 14 has a drift 141 that is provided with respect to die holder 13, and the stroking distance that can adjust drift 141 from adjustment seat 142 (only representing among the figure) with a die set 14 and a die holder 131; Cooperate and to consult Fig. 2, during operation, feed arrangement 12 carries blank 2 in regular turn to die holder 131, and via die holder 131 with blank 2 clampings location after, give punch forming by drift 141 at the blank in the die holder 131 2 again, so just can finish blank 2 stamping press.

Yet, smoothly whether blank 2 key of moulding, except that die holder 131 design of punching press, main be drift 141 and 131 stroking distances of die holder from the position adjustment, if stroking distance is from too short, easily cause not foot phenomenon of drift 141 punching presses, cause impacting the power deficiency, cause blank 2 punch formings bad, otherwise, when the stroking distance of adjusting seat 142 from long, can make the impulsive force of drift 141 excessive again, very easily make die holder 131 produce the loss phenomenons.And at present, the stroking distance of drift 141 is from adjustment, rely on operating personnel's experience to be adjusted fully with manual type, except that making that stamping forming product stability can't guarantee, and for the defective products that is produced in the punching course, can't in time find, be to monitor synchronously and management operations in the punching course, in case when the operating personnel finds, often produced too much defective products, cause the increase of manufacturing cost, have much room for improvement in fact.

The utility model content

The purpose of this utility model is to provide a kind of screw forming machine of tool sensing punch die pressure, and the punch die quality that it can monitor die set automatically helps to reduce the output of defective products, thereby reduces cost of goods manufactured.

To achieve these goals, the technical solution of the utility model is:

A kind of screw forming machine of tool sensing punch die pressure comprises a board, and one is located at the feed arrangement of importing blank on the board and in regular turn, and one accepts the module of blank that feed arrangement is imported, and at least one blank on the module is given stamping forming die set; Wherein, module has a die holder that blank can be given clamping location at least; Die set has a drift, and one can be for the adjustment seat of this drift setting; Board is provided with a pressure-sensing device, and one and the arithmetic unit that links of sensing apparatus, and pressure-sensing device has a sensing member at least, and this sensing member is located on the die set and directly towards drift, do the time spent when blank is subjected to drift on die holder, the suffered effect of impact power of blank is transmitted through the adjustment seat, is sensing member institute sensing, and transmit it in the arithmetic unit and show, differentiate, monitor blank punch forming situation with this.

Adopt said structure, the active force that the utility model utilizes sensing member sensing die set that the blank bump is produced, and change into numerical value by arithmetic unit, monitor the punch die quality of die set with this, monitoring institute value can be used as drift and adjusts the foundation that seat is adjusted, for the stroking distance of precisely adjusting die set from, the convenience of operation is provided, thereby reduced the output of defective products, avoided the increase of extra cost.

The specific embodiment

Fig. 3, shown in Figure 4, preferred embodiment for the screw forming machine 3 of the utility model tool sensing punch die pressure, this screw forming machine 3 includes a board 31, one is located on the board 31 and imports the feed arrangement 32 of blank 4 in regular turn, one accepts the module 33 of feed arrangement 32 input blanks 4, and at least one blank on the module 33 4 is given stamping forming die set 34; Wherein, module 33 has one at least can give blank 4 die holder 331 that clamping is located, in addition, die set 34 has a drift 341 with respect to die holder 331 settings, and one can be provided with and shape is the adjustment seat 342 of trapezoidal design for drift 341, so that the stroking distance of drift 341 is that example is represented with a die set 34 and a die holder 331 from being adjusted by the trapezoidal design of adjusting seat 342 only in present embodiment figure.

Still continuous above-mentioned, on board 31, be provided with a pressure-sensing device 35, and one and the arithmetic unit 36 that links of pressure-sensing device 35, wherein, pressure-sensing device 35 has a sensing member 351 at least, and this sensing member 351 is located at respectively on each die set 34, does the time spent when blank 4 is subjected to drift 341 on die holder 331, but the active force that sensing member 351 direct sensing are impacted to blank 4 shows, differentiates to transfer in the arithmetic unit 36.

Consult Fig. 3, Fig. 4, in the operation process, utilize feed arrangement 32 to import blank 4 in regular turn to die holder 331, and via die holder 331 with behind the blank 4 clampings location, again by drift 341 at 4 punch formings of the blank in the die holder 331, when 341 pairs of blanks of drift 4 carry out stamping forming moment, blank 4 can produce a reaction force on drift 341, this moment, sensing member 351 can sense the size of reaction force, and change into a numerical value by arithmetic unit 36 and shown, and differentiated through arithmetic unit 36, monitor in each blank 4 threading forming process with this whether defective products output is arranged, when the numerical exception of monitoring gained, the staff can handle by hard stop, avoid defective products to continue to make, so can effectively improve the punch die quality of blank 4, and reduce extra production cost; In addition, in view of in the past in blank 4 punch die forming processes, generally all carry out the stroking distance of die set 34 from adjustment with the operation experience with manual type by the Field Force, nowadays, utilize the monitoring numerical value of gained in each blank 4 punch forming, can allow the staff according to this monitoring gained numerical value adjusted as basis for estimation, so can precisely adjust suitable stroking distance from, and do not need to rely on again experienced staff, increased the convenience of operation.

In sum, the screw forming machine of the utility model tool sensing punch die pressure, by setting up pressure-sensing device, the active force that drift can be produced the blank bump is after arithmetic unit changes into a numerical value, monitor the punch die quality of die set according to this numerical value, thereby reduce the output of defective products, effectively promote product quality, and this numerical value is adjusted the adjustment foundation of seat as drift, for the stroking distance of precisely adjusting die set from, the convenience of operation is provided.

The above is preferred embodiment of the present utility model only, is not to limit practical range of the present utility model with this, and simple change and the modification of being done according to the design main points of this case all falls into protection domain of the present utility model generally.
