Abstract

The utility model relates to a kind of punching type punching head structure, comprise punching drive unit, cope match-plate pattern and punching head, device drift in described punching head, the upper end madial wall of punching head is arranged with chute, the slide block of described chute and drift upper end outer wall is slidably connected, and installs respectively spring in described chute; The lower surface of described drift and upper surface higher than lower surface and the upper surface of punching head, have buffer gap between the upper surface of drift and cope match-plate pattern respectively; The lower surface of described cope match-plate pattern with punching head upper surface near bulge loop.Delicate structure of the present utility model, adopts drift to combine with punching head, not only improves punching speed, also reduces work piece distortion, improves punching quality, and can avoid work piece to be stuck on punching head, realizes and once completes punching.

Description

Punching type punching head structure

Technical field

The utility model relates to panel beating technical field, especially the perforating press of thin plate panel beating.

Background technology

Existing hole punched device or perforating press, include frame, be fixed on the bed die in frame, the cope match-plate pattern moving up and down with respect to frame, is fixed with and the corresponding drift of described bed die on cope match-plate pattern, and cope match-plate pattern is connected with driving its oil cylinder moving up and down or cylinder.Under the drive of oil cylinder or cylinder, cope match-plate pattern drives drift to move up and down with respect to bed die, thereby on the work piece between drift and bed die, goes out the hole needing.The shortcoming that above-mentioned hole punched device or perforating press exist is: after punching head punching processing, the burr of bore edges is more, and hole crudy is not high; After punching, particularly thin plate sheet metal component is yielding for work piece, affects board quality.

Utility model content

The applicant, for the above-mentioned shortcoming of above-mentioned punching apparatus, provides a kind of punching type punching head structure, and it has delicate structure, feature that punching quality is high.

The technical scheme that the utility model adopts is as follows:

A kind of punching type punching head structure, comprise punching drive unit, cope match-plate pattern and punching head, device drift in described punching head, the upper end madial wall of punching head is arranged with chute, the slide block of described chute and drift upper end outer wall is slidably connected, and installs respectively spring in described chute; The lower surface of described drift and upper surface higher than lower surface and the upper surface of punching head, have buffer gap between the upper surface of drift and cope match-plate pattern respectively; The lower surface of described cope match-plate pattern with punching head upper surface near bulge loop.

The beneficial effects of the utility model are as follows:

Delicate structure of the present utility model, adopts drift to combine with punching head, not only improves punching speed, also reduces work piece distortion, improves punching quality, and can avoid work piece to be stuck on punching head, realizes and once completes punching.

Brief description of the drawings

Fig. 1 is main cutaway view of the present utility model.

In figure: 1, punching drive unit; 2, cope match-plate pattern; 21, bulge loop; 3, punching head; 31, chute; 4, drift; 41, slide block; 5, buffer gap; 6, spring.

Detailed description of the invention

Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described.

See Fig. 1, the utility model comprises punching drive unit 1, cope match-plate pattern 2 and punching head 3, and punching drive unit 1 drives cope match-plate pattern 2 to drive punching head 3 to pump; The interior device drift 4 of punching head 3, the upper end madial wall of punching head 3 is arranged with chute 31, chute 31 is slidably connected with the slide block 41 of drift 4 upper end outer walls, in described chute 31, installs respectively spring 6, and the two ends up and down of spring 6 are respectively near the bottom surface of slide block 41 and chute 31; Drift 4 device that staggers in punching head 3, the lower surface of drift 4 and upper surface, respectively higher than lower surface and the upper surface of punching head 3, have buffer gap 5 between the upper surface of drift 4 and cope match-plate pattern 2; The lower surface of described cope match-plate pattern 2 with punching head 3 upper surfaces near bulge loop 21, bulge loop 21 be placed on the upper end of drift 4 and with the upper surface of punching head 3 near.

When the utility model work, under the driving of punching drive unit 1, cope match-plate pattern 2 drives punching head 3 to carry out punching; In punch process, first the lower end of punching head 3 contacts work piece and cuts gradually, the distance that cope match-plate pattern 2 declines contacts with the upper surface of drift 4 after exceeding the height of buffer gap 5, drift 4 is exerted pressure and made drift 4 produce punching press to work piece, thereby auxiliary punching head 3 punchings, improve punching speed on the one hand, reduce on the other hand work piece distortion, improve punching quality, and can avoid work piece to be stuck on punching head 3.

More than describing is to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range is referring to claim, and without prejudice to spirit of the present utility model in the situation that, the utility model can be done any type of amendment.

Claims

1. a punching type punching head structure, comprise punching drive unit (1), cope match-plate pattern (2) and punching head (3), it is characterized in that: device drift (4) in described punching head (3), the upper end madial wall of punching head (3) is arranged with chute (31), described chute (31) is slidably connected with the slide block (41) of drift (4) upper end outer wall, installs respectively spring (6) in described chute (31); The lower surface of described drift (4) and upper surface higher than lower surface and the upper surface of punching head (3), have buffer gap (5) between the upper surface of drift (4) and cope match-plate pattern (2) respectively; The lower surface of described cope match-plate pattern (2) with punching head (3) upper surface near bulge loop (21).
