Large-bevel-angle circulating chamfering device for plastic building materials and using method of large-bevel-angle circulating chamfering device

Abstract

The invention discloses a large-bevel-angle circulating chamfering device for plastic building materials and a using method of the large-bevel-angle circulating chamfering device. The large-bevel-angle circulating chamfering device comprises a step springback type bevel angle adjusting device, an angle-adjustable self-springback type double-face planing device, a rolling pressing device and a reciprocating feeding type material collecting base. The invention belongs to the technical field of plastic building material chamfering machining, and particularly relates to the large-bevel-angle circulating chamfering device for plastic building materials and the using method of the large-bevel-angle circulating chamfering device The low-hardness plate-shaped building materials are circularly cut in a layered mode by changing the cutting angle of the double-face cutting tool from the relative horizontal angle to the final angle of the oblique angle, the oblique angle is adjusted through transverse sliding, and through cooperation of a hollow limiting column and an arc-shaped water drop type angle limiting groove, the limit angle of the rotary double-sided cutting tool is adjusted; and by means of a stepped elastic force supplementing assembly, the technical prejudice that elastic force is supplemented through a control module is overcome, and the technical effect of stepped elastic force supplementing is achieved only through a mechanical structure without depending on an electronic control module.

Description

technical field [0001] The invention belongs to the technical field of chamfering processing of plastic building materials, and specifically refers to a plastic building material large-bevel circular chamfering device and a use method thereof. Background technique [0002] In the field of construction engineering, it is often necessary to use light plate materials with low surface hardness but high structural strength. Due to the thick thickness of this material, it is often necessary to process a large bevel at the construction site to facilitate coordination with other structures. At present, this kind of on-site processing is mostly done by hand, and the tools used are mostly hand-held auxiliary processing tools such as hand saws and angle grinders; but this cutting method is not easy to ensure the accuracy of the final product, and the flatness is not high; currently on the market Equipment dedicated to cutting such large bevels has appeared, but they all have the follow...

Problems solved by technology

[0008] When cutting, in order to ensure that the feeding depth of each layer is roughly equal, the change range of the pre-tightening force is required to be as small as possible, and this requirement is generally guaranteed by a cumbersome automatic control device. Based on the principle of pre-action, the present invention creatively proposes a step In the front section of cutting, the elastic force of the first-order return spring provides preload, and in the back section of cutting, the supplementary preload is provided by the second-order memory alloy shrapnel after reaching the transformation temperature, so as to ensure the cutting pressure of the back section Sufficient and close to the front-end preload, it overcomes the technical prejudice that the elastic supplement must be realized through the control module, and realizes the step-by-step elastic supplementary technology only through a simple elastic structure and heat conduction structure without relying on any electronic control module Effectively solve the problem that the traditional elastic supplementary mechanism needs to rely on electronic control and the structure is too complicated
