Abstract
The utility model discloses a buffering-type bending machine, and the machine comprises a fixed frame. The upper part of the fixed frame is provided with a vertical connecting rod which is driven by an air cylinder. The tail end of the vertical connecting rod is provided with a sliding block seat which is guided by four vertical guide columns. The sliding block seat is equipped with a bending die which has an upper die and a lower die. A tungsten-steel roller pin is embedded in a part, which is bent and bears a force, of a punch block of the lower die. According to the utility model, the punch block in the bending die is changed, and the head part of the punch block is additionally provided with the tungsten-steel roller pin. After the improvement, the head part of the punch block cannot have burrs, and the tungsten-steel roller pin plays a role in buffering, thereby causing no crushing damage to a product. Compared with the prior art, the improved punch block cannot have burrs, plays a role in buffering in a process that the whole die is pressed downwards, cannot crush the product, and reduces the defect rate.
Description
Technical field
The utility model relates to a kind of bender, especially relates to a kind of buffer-type bender.
Background technology
In known technical field, existing bender is made up of punch press and Bending Mould, the former moves up and down by auxiliary mould, and the latter completes the head bending operation to product, and existing bender is carrying out product in the process of head bending, mold entirety presses down, drift in Bending Mould is relatively long, and drift may exist the situation of wearing and tearing, jagged on drift, mold integral presses down in this case, and the burr on drift can cause product bending part to weigh wounded.
Utility model content
Technical problem to be solved in the utility model is: a kind of buffer-type bender is provided, can effectively avoids producing burr after drift wearing and tearing, affect the quality of product.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of buffer-type bender, comprise fixed frame, be provided with the vertical connecting rod by air cylinder driven on the top of described fixed frame, end at described vertical connecting rod is provided with take-up housing, and described take-up housing is led by four vertical guide pillars, on described take-up housing, bending mold is installed, described bending mold is divided into upper die and lower die, and the stressed place of bending of the punch block on described counterdie embeds wolfram steel needle roller.
Adopt technique scheme, the beneficial effects of the utility model are: the punch block in the utility model change Bending Mould, and add a wolfram steel needle roller at the head of punch block, after so improving, the head of punch block be there will be no burr, and wolfram steel needle roller also plays the effect of a buffering, can be not again to product cause weigh wounded bad, compared with prior art: the drift of correcting one's mistakes soon can be not jagged, press down at mold integral the effect of playing buffering in process, can product not caused and be weighed wounded, reduce defective products rate.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the structural representation of bending mold in the utility model embodiment;
Fig. 3 is the local enlarged diagram at A place in Fig. 2;
Wherein: 1. fixed frame, 2. cylinder, 3. vertical connecting rod, 4. take-up housing, 5. vertical guide pillar, 6. bending mold, 61. patrixes, 62. counterdies, 63. punch blocks, 64. wolfram steel needle rollers.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Buffer-type bender as shown in FIG. 1 to 3, comprise fixed frame 1, be provided with the vertical connecting rod 3 being driven by cylinder 2 on the top of described fixed frame 1, be provided with take-up housing 4 at the end of described vertical connecting rod 3, described take-up housing 4 is led by four vertical guide pillars 5, on described take-up housing 4, bending mold 6 is installed, described bending mold 6 is divided into patrix 61 and counterdie 62, and the stressed place of bending of the punch block 63 on described counterdie 62 embeds wolfram steel needle roller 64.
Punch block in the utility model change Bending Mould, and add a wolfram steel needle roller at the head of punch block, after so improving, the head of punch block be there will be no burr, and wolfram steel needle roller also plays the effect of a buffering, can be not again to product cause weigh wounded bad, compared with prior art: the punch block of correcting one's mistakes can be not jagged, press down at mold integral the effect of playing buffering in process, can product not caused and be weighed wounded, reduced defective products rate.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done, within all dropping on protection domain of the present utility model.
