Abstract

The utility model discloses an edge cutter for cast trimmings. The utility model is primarily characterized in that the top part of a machine desk is provided with a pressure cylinder connected with a base plate, the bottom surface of the base plate is provided with a fixing seat with a pressure mold, and two slide tracks for a mold seat to slide are arranged on the machine desk. The mold seat is fixed with an edge cutting knife mold, and two sides which are opposite to the mold seat and the edge cutting knife mold are respectively provided with a clamp press device. When the utility model is used, cast objects can be put in an open mold cavity composed of inside knife tools of the edge cutting knife mold, and be pushed by the pressure mold with the utilization of the downward travel of the base plate. In addition, trimmings of the outer ring edge of the cast objects are cut through the edge cutting knife mold. In this way, the automatic control is formed.

Description

Casting thing burr border-cuting machine

The utility model relates to a kind of casting thing burr border-cuting machine.

At present, general metal casting thing is with the mode casting of sectional die, but because of the involutory interface and the nisi applying of mould, have plurality of gaps, therefore, the casting material can flow in the gap, after the moulding of casting thing, its relative mold interface place promptly produces burr, need process processing, so, for now, the finishing process of burr mainly is to utilize abrasive machine worn, when quite trouble is taken a lot of work again, and when using abrasive machine, the operator is vulnerable to injury, nonideal processing processing mode.

In view of this, but the purpose of this utility model is exactly the casting thing burr border-cuting machine of the burr that generated when a kind of automatic dressing mo(u)lding moulding will be provided.

For reaching above-mentioned purpose, technical solution adopted in the utility model is as follows: a kind of casting thing burr border-cuting machine, it mainly is at the top of a board one cylinder pressure to be set, cylinder pressure connects a substrate, the bottom surface of substrate is provided with a holder and a pressing mold, and the slide rail that twice mount a die holder is set on board, and die holder sets firmly one and cuts the edge cutting die, a cylinder pressure is also established in the rear end of die holder, in addition, the both sides of board are respectively established one and are pressed clamp device, and this pressure clamp device places with die holder and cut the corresponding both sides of edge cutting die, and the pressure clamp device also is provided with the lever pressure arm.

The shrinkage pool and the convex body of the concavo-convex cooperation of the corresponding formation of described die holder end face with the bottom surface of cutting the edge cutting die.

Described pressure clamps the bearing that installs a pivot bar rod-type pressure arm, and a pressure arm end of die holder in opposite directions is provided with press strip, and the other end connects a cylinder pressure.

Owing to adopt said structure, in use, place the saturating empty die cavity of cutting profile profile phase correspondence in the edge cutting die as long as will cast thing, utilize the stroke that moves down of substrate to make pressing mold push away striking and again by cutting the burr that the edge cutting die cuts its outer ring edge, in addition, cylinder pressure can be passed die holder automatically and stretch out, to set up cut the edge cutting die and place the casting thing very convenient, its monolithic finish action forms a control automatically, has promoted industrial benefit.

Below in conjunction with drawings and Examples the utility model is done further detailed description.

Fig. 1 is a main TV structure schematic diagram of the present utility model;

Fig. 2 is a sectional perspective structure chart of the present utility model;

Fig. 3 is that main apparent motion of the present utility model is made schematic diagram;

Fig. 4 is the action schematic diagram of overlooking of the present utility model.

As shown in Figure 1, 2, casting thing burr border-cuting machine described in the utility model is automatic control type facility designs, but the emphasis of the non-this patent of its inner automatically controlled part, so will not describe in detail, its entity machinery frame structure is as described below:

One cylinder pressure 11 is set at the top of a board 1, cylinder pressure 11 take-off levers connect a horizontal base plate 12, substrate 12 can longitudinally move after wearing knot guide rod 13, and the holder 14 of knot tool T-slot is established in the bottom surface of substrate 12, so that various pressing molds 2 can borrow the T body embedding knot at its top fixing, and the bottom of pressing mold 2 corresponding casting thing half contouring face and attachment face that moulding matches; In addition, the nearly centre of the table top of board 1 is established a fluting 15 and is connect down a Sheng plate 16, the both sides of its fluting 15 are provided with twice slide rail 3, this slide rail 3 mounts the die holder 4 of a slip, can cooperate on the die holder 4 and set firmly one and cut edge cutting die 5, and the end face of die holder 4 forms concavo-convex location shrinkage pool 41 that cooperates and convex body 51 with the bottom surface of cutting edge cutting die 5, align fixing for ease of calibration, also connect a cylinder pressure 17 behind the die holder 4, when moving, cylinder pressure 17 can do the front and back horizontal displacement by related die holder 4, simultaneously, respectively be provided with one in the both sides of board 1 and press clamp device 6, and be positioned at die holder 4 and cut edge cutting die 5 corresponding both sides, this pressure clamp device 6 connects the pressure arm 62 of making lever action with a bearing 61 pivots, and pressure arm 62 end of die holder 4 in opposite directions is connected with press strip 621, and the other end then is subjected to the ejection of a cylinder pressure 63, make press strip 621 ends of pressure arm 62 must move down to compress and fixedly cut edge cutting die 5 and die holder 4, make its unlikely vibrations.

When implementing by the said structure combination, shown in Fig. 3,4, after die holder 4 is subjected to the passing of cylinder pressure 17 to stretch out board 1, can mount changes the outfit cuts edge cutting die 5 and places casting thing 7 in cutting edge cutting die 5, the die holder 4 related edge cutting dies 5 of cutting are return, cylinder pressure 17 can provide one basic location, at this moment again, utilize the pressure arm 62 of clamping and pressing device 6 both sides to be compressed, then more firm; Then, passing cylinder pressure 11 descends substrate 12, then pressing mold 2 with under support to the casting thing of cutting in the edge cutting die 57, when pressing mold 2 pushing and pressing casting things 7 when cutting saturating empty die cavity that edge cutting die 5 inner cutters are constituted and move down, the burr of these casting thing 7 outer ring edges are subjected to eliminating of cutter blade and can repair the appearance profile of casting thing 7, make it no longer retain too much burr; Drop behind the fluting 15 of casting thing 7 that finishing finishes in containing plate 16 and delivering to outside collection tube through die holder 4, board 1 again.
