Abstract

The utility model relates to an adjustable sweepings sensing device arranged between the upper and the lower moulds of the punch. The utility model is characterized in that the front and the back proper positions of the upper and the lower composing members of the upper mould seat of the punch are provided with a sensing device; a base is buried on the lower composing member; the interior of the base is in screw connection with an adjustable pillar; the pillar is hollow, the bottom of the pillar is provided with a bottom support member, and the top end of the pillar is provided with a sensing block which exposes out of the top end of the pillar from the hollow part of the pillar; the pillar is adjusted to rotate, rise or drop down, and then the clearance between the top end of the sensing block and the bottom of the upper composing member is adjusted. When the lower part of the punch material member is provided with sweepings, the sensing block is contacted with the bottom of the upper composing member, the electronic sensing element causes the punch to automatically stop punching, and the utility model prevents a large quantity of degraded products from being punched and the mould from being damaged.

Description

Adjustable sweepings sensing device arranged between upper and lower mould of punch

Adjustable bits material sensing device between a kind of punching press upper and lower mould that is used for punch press belongs to the mechanical stamping technical field.

Usually in factory, use automatic punching machine, if no abnormal situation is promptly turned round automatically by punch press; as take place to fill up the long-pending bits material that has below the punching press materials and parts; it makes materials and parts produce bad finished product during punching press between upper and lower mould and mould is damaged, but punch press still works without cessation, and can produce a large amount of substandard products like this; and this bits material has a multiple reason; take place through regular meeting,, a kind of detection equipment is arranged abroad at this situation; but cost an arm and a leg, general medium-sized and small enterprises are difficult to accept.

The purpose of this utility model provide a kind of between the punch press upper and lower mould adjustable bits material sensing device, this device is for mechanical, when making the materials and parts below be lined with the bits material, perception and stop punch press work synchronously automatically.

Scheme of the present utility model is to constitute appropriate location, front and back between part up and down along mold, a sensing device is set, this device be under constitute on the part perforate and bury a pedestal underground, be spirally connected in the pedestal one and adjust mast, mast is a hollow, at the bottom of having one, its bottom holds part, a perception piece is arranged at an upper portion thereof, hold between part and the perception piece and be lined with spring at the end, the outside, top of adjusting mast is stretched out in the protruding end of perception piece, there is clamping screw both sides at pedestal, adjust the location or the pine of mast with control and unload adjustment, one of them clamping screw, lock a power lead, mast is adjusted in rotation, can make its lifting, to adapt to the thickness of different punching press materials and parts, after punching press materials and parts thickness is determined, adjust to adjust the height of mast, do not contact between the protruding end that makes the perception piece and the last formation part bottom surface, and normal stamping press, there are bits to expect in case punching press materials and parts below is long-pending, make down to constitute part by bed hedgehopping, the protruding end of perception this moment piece contacts with the bottom surface of formation part down, thereby connects an electronic inductor and punch press is stopped operation.

The utility model has the advantages that the thickness that can cooperate different punching press materials and parts, when the materials and parts below contained the bits material that is necessary, perception immediately also stopped the punch press operation simultaneously, prevents to produce a large amount of substandard products and mold damage, and cost is low, and is easy to use.

The utility model has following accompanying drawing:

Accompanying drawing 1 is the schematic diagram that the utility model is located at punch press upper bolster position.

Accompanying drawing 2 is three-dimensional exploded views of the present utility model.

Accompanying drawing 3 is assembled sectional views of Fig. 2.

Be described in detail embodiment of the present utility model below in conjunction with accompanying drawing.

As shown in Figure 1, general punch press is equipped with mold 10 and bed die 20, on having on the mold 10, constitute part 11 and constitute the upper bolster that part 12 constitutes down, there is baseplane 110 below of last formation part 11, constituting part 11 up and down, 12 appropriate location, front and back is provided with sensing device 30, it is to be embedded in down in the default hole 13 that constitutes part 12 with pedestal 31, it is formed as shown in Figure 2, pedestal 31 has central bore 32, contain internal screw thread 33 in the bottom in hole, the top of pedestal 31 is scalene cone and calibration loop 34 is arranged, and inserts an end in the bottom of medium pore 32 and holds part 35, and it has a central boss 36; The lower end of adjusting mast 60 is provided with the internal screw thread 33 of external screw teeth 61 to connect pedestal 31, is provided with a path medium pore 62 on its top and communicates with medium pore 63, then is provided with polygonal circle flange 64 below its top medium pore 62, is carved with scale 600 on the flange 64; 70 of one perception pieces are provided with a chassis portion 71 and a path cylinder 72, and its chassis is pressed on the inner top surface of

medium pore

63, and 72 of path cylinders stretch out the path medium pore 62 of mast 60; Hold and insert a spring 80 between the part 35 at the end of the chassis 71 of perception piece 70 and the bottom surface of mast 60; One set bolt 90 is locked by the lateral aperture of pedestal 31, location or pine with control mast 60 are unloaded adjustment, another radial bolts 900, another side from pedestal 31, lock advances the brace of a lead 901, between bolt 900 front ends and perception piece 70 periphery walls, be situated between and adorn a spring 902, to form against contact; When using the utility model, different-thickness according to the punching press materials and parts, rotate the flange 64 of mast 60, make the bottom surface 110 of protruding end 700 and last formation part 11 of the perception piece 70 on mast top keep standard clearances and do not contact, but make the normal operation of punch press energy, when the punching press materials and parts of below are long-pending when the bits material is arranged, make down and constitute part 12 by bed hedgehopping, thereby make the protruding end 700 of perception piece 70 contact and connect an electronic induction element with the following bottom surface 110 that constitutes part 11, and punch press is stopped operation, thereby can prevent to produce a large amount of substandard products and mold damage; Accompanying drawing 3 is the cutaway views after the utility model assembling, and the structural relation among the figure between each parts is narrated in front, no longer heavily chats.
