Problems solved by technology

[0003] The existing scraper has the following disadvantages: Since the teeth are integrally welded, the entire tool needs to be replaced when repairing the teeth, and after the overall replacement of the tool, it is difficult to maintain the same size and position accuracy as the original tool, and it needs to be readjusted Equipment; while the traditional scraper cutting method is single-tooth cutting and one-time forming, the cutting resistance of the tool is large, and the processing quality is poor

Embodiment 1

[0017] Such as figure 1 As shown, the scraper used for processing concave profiles of wood and plastic boards according to the present invention includes a cutter body 1 , a cutter tooth holder 2 and a cutter tooth 3 . The cutter tooth seat 2 and the cutter body 1 are fixed by bolts 5, the number of cutter teeth 3 is five, and the cutter teeth 3 are arranged in a straight line on the cutter tooth seat 2, and the cutter teeth 3 include the tooth body 3-1 and are welded and fixed on the The tooth head 3-2 on the tooth body 3-1 is also fixed by the bolt 5 between the tooth body 3-1 and the tooth seat 2. Such as figure 2 As shown, the height and width of the tooth head 3-2 of each knife tooth 3 increase in steps from the frontmost knife tooth 3 to the rearmost knife tooth 3 . The height dimension of the tooth head 3-2 of the first knife tooth 3 at the front is h1, the width dimension is b1, the height dimension of the tooth head 3-2 of the second knife tooth 3 in the middle is ...

Embodiment 2

[0020] Such as image 3 As shown, the cutter body 1 is in the shape of a disc, and the center of the cutter body 1 is provided with a central axis hole 4, and there are 6 tooth holders 2 evenly distributed on the outer peripheral edge of the cutter body 1, and the cutter holder 2 and the cutter body 1 are connected by bolts. 5 is fixed, and three cutter teeth 3 are arranged in a straight line on each cutter tooth seat 2. The cutter teeth 3 include a tooth body 3-1 and a tooth head 3-2 welded and fixed on the tooth body 3-1. Also be fixed by bolt 5 between body 3-1 and cutter tooth seat 2. Such as Figure 4 As shown, the height and width of the tooth head 3-2 of each knife tooth 3 increase in steps from the frontmost knife tooth 3 to the rearmost knife tooth 3 . The height dimension of the tooth head 3-2 of the first knife tooth 3 at the front is h1, the width dimension is b1, the height dimension of the tooth head 3-2 of the second knife tooth 3 in the middle is h1+h2, and t...

Abstract

The invention discloses a scraper for processing a concave profile of wood and plastic materials. The scraper comprises a cutter body, a blade tooth base and blade teeth, wherein the blade tooth base is detachably connected with the cutter body; the number of blade teeth is more than or equal to 2; the blade teeth are distributed on the blade tooth base in an in-line manner; the blade teeth comprise tooth bodies and tooth heads fixed on the tooth bodies; the height and width sizes of each tooth head of each blade tooth are increased from the most front blade tooth to the most rear blade tooth in an echelon manner. The scraper has the advantages that the blade tooth base and the cutter body are in detachable connection, when the blade teeth are polished, the scraper does not need to be integrally detached and replaced, and the position of the cutter body cannot be replaced, so that the accuracy of size and position of the scraper can be guaranteed; the number of blade teeth is more than or equal to 2, the blade teeth are distributed on the blade tooth base in the in-line manner, the height and width sizes of each tooth head of each blade tooth are increased from the most front blade tooth to the most rear blade tooth in an echelon manner, the cutting mode of the scraper is changed from single-tooth cutting into multi-tooth layered cutting, the scraper is subjected to small cutting resistance and is high in processing quality.

Description

technical field [0001] The invention relates to a cutting tool, in particular to a scraper for processing concave profiles of wood and plastic plates. Background technique [0002] In the production process of wood and plastic boards, there is a process of tongue-and-groove processing, which needs to be completed with cutting tools. At present, most of the wooden and plastic boards adopt the locking profile, and the locking profile is divided into various structural types. According to different locking structures, different tool configuration schemes are required. For some buckle profiles with concave structures, it is impossible to process them with rotary tools, and scrapers are needed to complete them. [0003] The existing scraper has the following disadvantages: Since the teeth are integrally welded, the entire tool needs to be replaced when repairing the teeth, and after the overall replacement of the tool, it is difficult to maintain the same size and position accur...
