Description

Technical Field

[0001] This utility model belongs to the field of granite cutting technology, and specifically relates to a gang saw head for granite cutting. Background Technology

[0002] In the stone processing industry, marble slab cutting commonly employs reciprocating gang saws, with existing saw blades consisting of a steel strip and a cutting head. While existing gang saw cutting heads for granite cutting meet the basic requirements for granite cutting and can prevent rust at the connection point between the cutting head and the steel strip by incorporating a protective structure, thus preventing the cutting head from easily detaching from the substrate during stone cutting, the cutting head and steel strip are fixed together by an interlocking method, followed by welding at the connection point. Due to the lack of a restraining structure before welding, the cutting head must be pressed firmly against the steel strip during the welding process, which is extremely time-consuming and labor-intensive.

[0003] For example, the utility model patent with announcement number CN 218429206 U discloses a gang saw blade head structure. In the technical solution of this patent, after the blade head is inserted and fixed together with the steel strip, there is no limiting structure to keep the blade head and the steel strip tightly inserted and fixed. Therefore, in the process of welding the connection between the blade head and the connecting plate and the side plate, it is necessary to take additional measures to press the blade head tightly onto the steel strip, which is very troublesome and cannot fully meet people's usage needs. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the existing technology by providing a gang saw head for cutting granite. It not only meets the basic requirements for cutting granite, but also, through a limiting structure, ensures that the cutter head and the steel strip are inserted and fixed together, maintaining a tight and secure connection. This allows users to easily weld and fix the connection between the cutter head and the steel strip, thus better meeting people's needs.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a gang saw blade head for cutting granite includes a steel strip arranged in a left-right direction, a plurality of blades evenly spaced at the bottom of the steel strip in the left-right direction, a plurality of bottom-opening connecting slots arranged at the bottom of the steel strip in the left-right direction, a connecting plate adapted to the connecting slots being provided at the top of the plurality of blades, a connecting screw for screwing and fixing the connecting plate on the plurality of connecting slots, a threaded connecting hole adapted to the corresponding connecting screw on the plurality of connecting plates, a sealing and protective module being provided at the connection between the plurality of connecting plates and the corresponding connecting slots, and the connection between the connecting plates and the connecting slots being welded and fixed.

[0006] As a further improvement of this utility model, multiple first welding through holes are respectively provided on multiple connecting slots.

[0007] As a further improvement of this utility model, the sealing protection module includes a sealing sleeve that is vertically sleeved on the connecting plate and used to fit and connect the connecting plate and the connecting slot. The sealing sleeve is also provided with a fastening screw for screwing and fixing the connecting slot. A baffle that matches the bottom of the sealing sleeve is provided on the outer wall of the connecting plate. A clearance gap is provided between the baffle and the bottom of the connecting slot. The connecting slot is provided with a threaded fastening hole that matches the fastening screw. The connection between the sealing sleeve and the connecting slot is also welded and fixed. The top of the sealing sleeve is located below the connecting screw. The connection between the sealing sleeve and the connecting slot is also welded and fixed. The connection between the sealing sleeve and the connecting plate is also welded and fixed.

[0008] As a further improvement of this utility model, the sealing sleeve is also provided with a plurality of second welding through holes corresponding to the position of the connecting slot.

[0009] As a further improvement of this utility model, the connecting slot is provided with a first clearance groove that is adapted to the connecting screw.

[0010] As a further improvement of this utility model, the sealing sleeve is provided with a second clearance groove that is adapted to the fastening screw.

[0011] As a further improvement of this utility model, a reinforcing plate is also provided between the side end of the connecting slot and the bottom of the steel strip.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] Firstly, the user can engage and fix the connecting plate with the connecting slot, then pass the connecting screw through the side wall of the connecting slot and screw it into the threaded connection hole, thus ensuring that the connecting plate is tightly engaged and fixed with the connecting slot. Afterwards, the user can easily weld and fix the connection between the connecting slot and the connecting plate. Next, the sealing sleeve can be placed on the connecting plate from bottom to top, with the bottom inner wall of the sealing sleeve abutting against the bottom of the connecting slot. Then, the fastening screw can pass through the side wall of the sealing sleeve and screw it into the threaded fastening hole, thus ensuring that the sealing sleeve and the connecting slot are tightly engaged and fixed. Finally, the connection between the sealing sleeve and the connecting slot, and the connection between the bottom of the sealing sleeve and the connecting plate can be welded and fixed.

[0014] Secondly, through the first welding through hole, the user can also weld and fix the connection between the side end of the connecting plate and the connecting slot. Through the second welding through hole, the user can also weld and fix the connection between the side end of the sealing sleeve and the connecting slot.

[0015] Thirdly, the first clearance groove prevents the connecting screw from protruding outwards, thus preventing the connecting screw from affecting the cutting and processing of the granite; the second clearance groove prevents the fastening screw from protruding outwards, thus preventing the fastening screw from affecting the cutting and processing of the granite.

[0016] Fourth, the reinforcement plate can improve the firmness of the connection between the connecting slot and the steel strip. Attached Figure Description
