Low damage welding ceramic plate

Abstract

The low-damage welding porcelain plate is made of ceramic material and has a double-step shape. It is provided with two main parts: a protection position and a protection position bottom. The protection position bottom consists of protection position bottom I and protection position bottom II, which support the front of the cutter head and the groove surface of the cutter head. Protection position bottom I is adjacent to the protection position, and there is an inner concave on the porcelain plate protection position for avoiding the tip of the cutter head. The protection position is respectively connected in sequence by a protection position concave surface, a protection position arc surface, and a protection position top surface. The porcelain plate protection position bottom I and the porcelain plate protection position bottom II have a supporting step, and the step height matches the height difference between the front of the cutter head and the tip of the cutter head. The present invention optimizes and adjusts the physical contact stress point so that the cutter head can reasonably avoid the hidden crack defect at the cutting edge of the cutter head when the welding heating process is subjected to stress.

Description

Technical Field

[0001] The invention relates to a welding porcelain plate capable of reducing welding damage. Background Art

[0002] High-frequency welding technology has become very popular in the field of circular saw blade manufacturing. There are two types of blade heads in the saw blade welding process, one is a rectangular blade head, and the other is a special-shaped blade head. The rectangular blade head is mainly used for ordinary alloy circular saw blades, installed on ordinary cutting machines, and used to cut relatively easy-to-cut materials such as wood products, plastic products, and artificial boards. However, special-shaped blade heads are mainly used in metal cold saws, installed on metal circular saw machines to cut metal bars or metal hollow materials. The special-shaped blade head is made of metal ceramic, which is characterized by hardness and very brittleness, especially during the welding heating process, it is easy to break teeth due to external forces.

[0003] The welding of rectangular blades generally uses a ceramic plate with a single boss; the welding of metal ceramic special-shaped blades uses a double boss. The structure of the ceramic plate designed by the present invention can effectively reduce the defect effect of the important parts of the special-shaped blade during the high-temperature heating process.

[0004] Before the invention of metal cutting circular saw blades, early circular saw blades mainly used rectangular blade heads, which would not encounter the welding problems of existing special-shaped blade heads during the welding process. Moreover, the blade heads of early circular saw blades were made of cemented carbide, while the current material is metal ceramic, which is relatively brittle and will be relatively brittle when subjected to stress during heating. Therefore, this patent can effectively solve the hidden cracks or defects generated during the welding process, and provide better help for the product in improving the stability of subsequent metal cutting. Summary of the invention

[0005] The present invention aims to overcome the single disadvantage of the existing ceramic plate technology and proposes a low-damage welding ceramic plate design.

[0006] The present invention aims at the hidden damage existing in the existing metal cold saw welding process (mainly manifested in the tooth defects), and effectively solves the hidden defects generated during the welding heating and stress process. At the same time, a customized low-damage welding ceramic plate design is proposed for metal ceramics of different shapes and sizes. Mainly through the optimization and adjustment of the physical contact stress point, the cutter head can reasonably avoid the hidden crack defects at the cutting edge of the cutter head when the welding heating process is stressed.

[0007] The low-damage welding porcelain plate is characterized in that: it is made of ceramic material, including a top surface 22, a bottom surface 24, a back surface 23, and a front surface, the bottom surface 24 and the back surface 23 are in contact and fixed with the mechanical parts of the welding equipment; the upper part of the front surface is provided with a protective position top surface 211 and a protective position 21 for avoiding the tip of a cutter head, and the lower part of the front surface is connected to a protective position bottom protruding forward; the protective position bottom is composed of a protective position bottom I 27 and a protective position bottom II 26, and the protective position bottom I 27 and the porcelain plate protective position bottom II 26 are in a double-step shape, and the protective position bottom I 27 and the protective position bottom II 26 respectively support the cutter head of the cutter head The front face 13 and the cutter head concave surface 17, the top surface 211 of the protection position of the ceramic plate 2 contacts the upper part of the top surface 14 of the cutter head; the bottom Ⅰ27 of the protection position is adjacent to the protection position 21, and there is an inner recess on the protection position 21 for avoiding the tip of the cutter head; the protection position 21 is composed of the inner recess point 28 of the protection position, the concave surface 213 of the protection position, the arc surface 212 of the protection position, and the top surface 211 of the protection position connected in sequence; the bottom Ⅰ27 of the protection position and the bottom Ⅱ26 of the ceramic plate protection position have a height difference support step 271, and the height of the height difference support step 271 matches the height difference between the front face 13 of the cutter head and the tip 15 of the cutter head.

[0008] Preferably, the total height difference between the protective arc surface 212 and the protective concave surface 213 is smaller than the height of the top surface 14 of the cutter head.

[0009] Preferably, the front of the bottom surface 24 is adjacent to the bottom surface 263 of the ceramic plate protection position; the front end of the protection position 21 is the protection position front 262, and the ceramic plate protection position 262 enters into the saw blade chip groove.

[0010] Preferably, the top surface 14 of the cutter head is relatively parallel to the top surface 211 of the protection position, and the angle deviation is within 1°.

[0011] Preferably, the bottom surface II of the protection position and the bottom surface I of the protection position are both planes parallel to the top surface 22 and the bottom surface 24 .

[0012] During welding, the low-damage welding ceramic plate will push the cutter head toward the ground under the action of force. The contact surface between the ceramic plate and the cutter head is divided into the contact support surface and the force-bearing surface. The contact support surface is mainly the bottom of the protection position I and the bottom of the protection position II, and the force-bearing surface is mainly the top surface of the cutter head and the bottom surface of the groove of the cutter head. During the force-bearing process, the tip of the cutter head successfully avoids the force-bearing point.

[0013] The beneficial effect of the present invention is that compared with traditional welding ceramic plates, while ensuring the welding angle accuracy and welding strength, it can significantly reduce the hidden damage to the cutter head caused by the welding process, provide a reliable guarantee for the stability of the cutter head when cutting metal materials subsequently, and effectively reduce the tooth breakage of the cutter head caused by hidden defects during the cutting process.

[0018] The present invention is further described below with reference to the accompanying drawings

[0019] The low-damage welding ceramic plate described in the present invention includes two main parts, namely, a protection position 21 and a protection position bottom. The protection position bottom includes a protection position bottom I27 and a protection position bottom II26. Above the protection position 21 is the top surface 22, next to the back surface 23, and the surface opposite to the top surface 22 of the ceramic plate is the bottom surface 24. The bottom surface 24 and the back surface 23 are in contact and fixed with the mechanical parts of the welding equipment. Next to the front of the bottom surface 24 is the protection position lower bottom surface 263. At the front end of the ceramic plate 2 is the protection position front 262, which needs to enter the concave part of the saw blade chip groove. There is a height difference support step surface 271 between the protection position bottom I27 and the protection position bottom II26, and the height of the support step surface 271 is consistent with the horizontal height difference between the front 13 of the cutter head and the tip 15 of the cutter head, which effectively ensures that the cutter head 1 can be placed on the protection position bottom I27 and the protection position bottom II26 of the ceramic plate 2 to be relatively stable. The front face 13 of the cutter head is placed on the bottom surface II 261 of the protection position, the concave face 17 of the cutter head is placed on the bottom surface I 272 of the protection position, and the upper half of the top face 14 of the cutter head is in contact with the top surface 211 of the protection position of the ceramic plate 2 .

[0020] The top surface 14 of the cutter head is relatively parallel to the top surface 211 of the low damage welding ceramic plate 2, and the angle deviation is within 1°. The bottom surface II26 and the bottom surface I27 of the low damage welding ceramic plate 2 are both parallel to the top surface 22 and the bottom surface 24.

[0021] During the contact process, the support point 273 at the bottom of the protection position of the ceramic plate 2 contacts the bottom surface of the cutter head groove. At the same time, the tip 15 of the cutter head only contacts the bottom surface of the ceramic plate protection position, and the cutter head does not contact in the horizontal direction, which can effectively reduce the stress damage during the welding heating process. The protection position 21 is composed of four parts: the inner concave point 28 of the protection position, the concave surface 213 of the protection position, the arc surface 212 of the protection position, and the top surface 211 of the protection position. The total height difference of the inner concave arc surface 212 of the protection position and the concave surface 213 of the protection position is smaller than that of the top surface 14 of the cutter head, and is approximately 1 / 3 to 1 / 2 of the top surface of the cutter head.

The protection scope of the present invention should not be regarded as limited to the specific forms described in the embodiments. The protection scope of the present invention also includes equivalent technical means that can be thought of by those skilled in the art based on the inventive concept.
