Abstract

The invention relates to a punching head structure for sheet metal punching. The punching head structure for sheet metal punching comprises a punching driving device, an upper die plate and a punching head. A punch is arranged in the punching head. Sliding grooves are symmetrically formed in the inner side wall of the upper end of the punching head. The sliding grooves are slidably connected with sliding blocks on the outer wall of the upper end of the punch. A plurality of layers of cushions are arranged in the sliding grooves correspondingly. The lower end face and the upper end face of the punch are higher than the lower end face and the upper end face of the punching head correspondingly. A buffering gap exists between the upper end face of the punch and the upper die plate. The lower surface of the upper die plate is provided with a convex ring abutting against the upper end face of the punching head. The punching head structure for sheet metal punching is exquisite in structure; by combining the punch with the punching head, the punching speed is increased, deformation of a machined part is reduced, and the punching quality is improved; and furthermore, the situation that the machined part is clamped on the punching head can be avoided, and punching can be completed at a time.

Description

The punching head structure of panel beating punching processing

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, the bed die all include frame, being fixed in frame, the cope match-plate pattern moved up and down relative to frame, cope match-plate pattern is fixed with drift corresponding with described bed die, cope match-plate pattern and drive its oil cylinder moved up and down or cylinders。Under the drive of oil cylinder or cylinder, cope match-plate pattern drives drift to move up and down relative to bed die, thus going out the hole of needs on the work piece between drift and bed die。Above-mentioned hole punched device or perforating press have the drawback that: after punching head punching processing, the burr of bore edges is more, and hole machined is of low quality；After punching, particularly thin plate sheet metal component is yielding for work piece, affects board quality。

Summary of the invention

The applicant is for the disadvantages mentioned above of above-mentioned punching apparatus, it is provided that the punching head structure of a kind of panel beating punching processing, the feature that it has delicate structure, punching quality is high。

The technical solution adopted in the present invention is as follows:

A kind of punching head structure of panel beating punching processing, including punching driving device, cope match-plate pattern and punching head, device drift in described punching head, the medial wall, upper end of punching head is arranged with chute, described chute is connected with the skid of drift upper end outer wall, difference device multilamellar cushion pad in described chute；The lower surface of described drift and upper surface are respectively higher than lower surface and the upper surface of punching head, have buffer gap between upper surface and the cope match-plate pattern of drift；The lower surface of described cope match-plate pattern with punching head upper surface against bulge loop。

Beneficial effects of the present invention is as follows:

The delicate structure of the present invention, adopts drift to combine with punching head, not only improves punching speed, also reduces work piece deformation, improves punching quality, and work piece can be avoided to be stuck on punching head, it is achieved once complete punching。

Detailed description of the invention

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

Seeing that Fig. 1, the present invention include punching driving device 1, cope match-plate pattern 2 and punching head 3, punching driving device 1 drives cope match-plate pattern 2 to drive punching head 3 to pump；Device drift 4 in punching head 3, the medial wall, upper end of punching head 3 is arranged with chute 31, the slide block 41 of chute 31 and drift 4 upper end outer wall is slidably connected, and difference device multilamellar cushion pad 6 in described chute 31, the two ends up and down of multilamellar cushion pad 6 are respectively against the bottom surface of slide block 41 and chute 31；Drift 4 staggers device in punching head 3, and namely the lower surface of drift 4 and upper surface are respectively higher than lower surface and the upper surface of punching head 3, have buffer gap 5 between upper surface and the cope match-plate pattern 2 of drift 4；The lower surface of described cope match-plate pattern 2 with punching head 3 upper surface against bulge loop 21, bulge loop 21 be placed on drift 4 upper end and with the upper surface of punching head 3 against。

Above description is explanation of the invention, is not the restriction to invention, and limited range of the present invention is referring to claim, and when without prejudice to the spirit of the present invention, the present invention can do any type of amendment。
