Description

Material cutting head mechanism

Technical Field

The utility model relates to a processing equipment technical field, in particular to blank head mechanism.

Background

Some notebook cover plates are manufactured by combining a metal part and plastic, and the manufacturing method is to place the metal part into a cavity for injection molding, and then inject the plastic into the cavity so that the metal part and the plastic are combined with each other. Because of the flow path influence of the plastic, the initially formed whole may leave many slugs, some of which can be cut from the longitudinal direction and others of which require cutting from the transverse direction. In the past, two cutting modes need to be completed by an independent mechanism, and the cost of parts is high. Therefore, a new blanking head mechanism is needed to solve the problem.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a blank head mechanism can conveniently accomplish vertical excision and the horizontal excision of stub bar.

The utility model discloses a following technical scheme realizes above-mentioned purpose: the utility model provides a blank head mechanism, includes the fixed plate, locates two little slip table cylinders and a big slip table cylinder of fixed plate lower part, straight sword is driven separately to little slip table cylinder, special-shaped sword is driven to big slip table cylinder, the most advanced of special-shaped sword inclines to one side.

Specifically, the two straight knives are parallel to each other.

Specifically, the top end of a shaft lever of the small sliding table cylinder is provided with a supporting block of a right-angle structure, the inner side of the supporting block is provided with a fixed block, and the straight knife is clamped between the supporting block and the fixed block.

Adopt above-mentioned technical scheme, the utility model discloses technical scheme's beneficial effect is:

the stub bar cutting mechanism not only can longitudinally cut off the stub bar on the notebook cover plate by using the straight knife, but also can transversely cut off other stub bars by using the special-shaped knife without damaging the rest parts of the product, and has compact mechanism and convenient use.

Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1 and 2, the utility model discloses a blank head mechanism, including fixed plate 1, locate two little slip table cylinders 2a, 2b and a big slip table cylinder 4 of fixed plate 1 lower part, straight sword 3a, 3b are driven separately to little slip table cylinders 2a, 2b, and special-shaped sword 5 is driven to big slip table cylinder 4, special-shaped sword 5's most advanced to a lopsidedness. The fixed plate 1 is provided on a lateral shifting device. The inclined design of the profiled knife 5 is mainly intended to avoid damaging the rest of the product when moving. When the stub bar needs to be longitudinally cut off, the special-shaped cutter 5 retracts, and the two small sliding table cylinders 2a and 2b respectively drive the straight cutters 3a and 3b to cut downwards to complete longitudinal cutting; when the stub bar needs to be transversely cut off, the two straight cutters 3a and 3b retract, the large sliding table cylinder 4 enables the special-shaped cutter 5 to transversely move, and one or more stub bars are scraped by utilizing the inclined tip. The mechanism is compact and the use is convenient.

As shown in fig. 1, the two straight knives 3a, 3b are parallel to each other. The material head which generally needs to be longitudinally cut is generated by the plastic which transversely passes through, and the material head are connected with the main body in the inlet and outlet directions of the flow, so that two parallel straight knives 3a and 3b are needed for cutting.

As shown in fig. 1, the top ends of the shaft levers of the small sliding table cylinders 2a and 2b are provided with supporting blocks 6 with right-angle structures, the inner sides of the supporting blocks 6 are provided with fixed blocks 7, and the straight cutters 3a and 3b are clamped between the supporting blocks 6 and the fixed blocks 7. The two blanking positions of the product slitting are relatively close, but the small slipway cylinders 2a, 2b themselves have a relatively large width. The supporting block 6 enables the positions of the two straight knives 3a and 3b to be close to each other, and can also play a good supporting role in the structures of the straight knives 3a and 3 b.

What has been described above are only some embodiments of the invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which are within the scope of the invention.
