Abstract

The invention relates to a punching type punching head structure. The punching type punching head structure comprises a punching drive device, an upper template and a punching head. A punch is arranged in the punching head. Slide grooves are symmetrically formed in the inner side wall of the upper end of the punching head and are connected with slide blocks on the outer wall of the upper end of the punch in a sliding mode. Springs are arranged in the slide grooves respectively. The lower end face of the punch is higher than the lower end face of the punching head. The upper end face of the punch is higher than the upper end face of the punching head. A buffer gap is formed between the upper end face of the punch and the upper template. The lower surface of the upper template is provided with a protruding ring which abuts against the upper end face of the punching head. The punching type punching head structure is exquisite in structure, the punch and the punching head are combined, and therefore the punching speed is increased, deformation of a machined piece is reduced, punching quality is improved, the machined piece can be prevented from being clamped on the punching head, and punching can be completed at a time.

Description

Punching type punching head structure

Technical field

The present invention 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.

Summary of the invention

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 solution adopted in the present invention 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.

Beneficial effect of the present invention is as follows:

Delicate structure of the present invention, 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.

Accompanying drawing explanation

Fig. 1 is main cutaway view of the present invention.

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.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.

See Fig. 1, the present invention includes punching drive unit 1, cope match-plate pattern 2 and punching head 3, 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 drift 4 upper end and with the upper surface of punching head 3 near.

When the present invention works, 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, after surpassing the height of buffer gap 5, the distance that cope match-plate pattern 2 declines contacts with the upper surface of drift 4, drift 4 is exerted pressure and made 4 pairs of work pieces of drift produce punching press, 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 explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and without prejudice to spirit of the present invention in the situation that, the present invention can do any type of modification.

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).
