Description

Technical Field

[0001] This utility model relates to a shovel blade, and more particularly to a shovel blade structure, belonging to the field of shovel blade technology. Background Technology

[0002] Automatic metal fin forming machines are mainly used for processing copper and aluminum metal fins, and are widely used in industries such as aviation, aerospace, high-speed rail, photovoltaics, electronics, air conditioning, and bathroom heaters. The finning blade and blade holder are its core components. When processing copper and aluminum metal fins, adjusting the position and angle of the finning blade is crucial. The finning blade and blade holder are easily loosened due to their simple fixing method. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing shovel and shovel holder structures, which have simple fixing methods and are prone to loosening. This utility model provides a shovel structure that can achieve simple installation of the shovel and shovel holder while maintaining a stable structure that is not easily loosened; it is also durable and provides stable cutting.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a shovel structure, including a shovel base and a shovel body, wherein the shovel base is a polygonal column, arranged vertically, and includes upper and lower end faces and several side vertical faces;

[0005] The shovel body also includes a back blade, a shovel blade, and several fixing bolts. The back blade includes an A-side, a B-side, and a front end, and the thickness of the back blade is h. The A-side is the inner side that is fixedly fitted to the shovel blade, and the B-side is the outer side that is assembled and fitted to the shovel blade seat. The A-side and B-side of the back blade are parallel to each other.

[0006] Since the A and B sides of the back knife are parallel to each other, the installation direction of the scraper is adjusted by the installation direction of the scraper seat. The angle between the scraper and the processed strip profile is adjusted by rotating the scraper seat clockwise or counterclockwise.

[0007] The shovel base has a slot on one side, and the back blade B is engaged in the slot for a tight fit. The shovel has several screw holes A evenly distributed vertically in the middle, and the back blade has several screw holes B corresponding to the screw holes A on the shovel. The slot has several blind holes corresponding to the screw holes B on the back blade. The shovel, the back blade, and the shovel base are fixed together by fixing bolts passing through the screw holes A and B, screwing into the blind holes, and tightening them.

[0008] The blade holder is a pentagonal prism.

[0009] The shovel body includes 5 fixing bolts. 5 screw holes A are evenly arranged vertically in the middle of the shovel. 5 screw holes B are arranged on the back blade at the positions corresponding to the screw holes A of the shovel. 5 blind holes are arranged in the slot at the positions corresponding to the screw holes B of the back blade.

[0010] The shovel has one blade at each of its front and rear ends. The blades at the front and rear ends are symmetrically arranged in the front-rear direction so that the blade at the front end can be reversed and installed in the front-rear direction after it wears out, so as to continue to use it, thereby improving the utilization rate and extending the service life.

[0011] The back of the shovel is provided with corrugated grooves, forming a wavy blade at both ends of the blade tip.

[0012] The back of the shovel, the A-side of the back blade, and the bottom surface of the slot of the shovel holder are parallel to each other, and the angle α between the back of the shovel and the horizontal direction is 40-52°.

[0013] The included angle β of the blade of the shovel is 40-49°.

[0014] Compared with existing technologies, the advantages of this invention are as follows: a back blade is provided between the scraper and the scraper holder, with its front surface A and back surface B being parallel to each other. After the position of the scraper holder is determined, the distance between the scraper and the strip being processed is directly adjusted by the thickness h of the two parallel back blades. Secured by multiple fixing bolts, the scraper structure is stable and not easily loosened. It is durable, provides stable scraping, has a sharp blade, and low cutting resistance.

The back blade 2 includes an A-side 201, a B-side 202, and a front end, and the thickness of the back blade 2 is h. The A-side 201 is the inner surface that is fixedly fitted to the shovel 3, and the B-side 202 is the outer surface that is assembled and fitted to the shovel base 1. The A-side 201 and B-side 202 of the back blade 2 are parallel to each other.

[0028] Since the A-side 201 and B-side 202 of the back blade 2 are parallel to each other, the installation direction of the scraper 3 is adjusted by the installation direction of the scraper seat 1. The scraper seat 1 can be rotated clockwise or counterclockwise to adjust the angle between the scraper 3 and the processed strip profile.

[0029] like Figure 1 , Figure 3 and Figure 5 As shown, a slot 103 is provided on one side of the scraper holder 1, and the back blade B side 202 is engaged in the slot 103 for tight connection; five screw holes A 302 are evenly arranged vertically in the middle of the scraper 3, and five screw holes B 203 are provided on the back blade 2 at the corresponding positions of the screw holes A 302 of the scraper 3. Five blind holes 104 are provided in the slot 103 at the corresponding positions of the screw holes B 203 of the back blade 2. The scraper 3, the back blade 2 and the scraper holder 1 are fixed by a fixing bolt 4 passing through the screw holes A 302 and the screw holes B 203, screwing into the blind holes 104 and tightening it.

[0030] like Figure 1 and Figure 3 As shown, the shovel holder 1 is a pentagonal prism.

[0031] like Figure 4 As shown, the shovel 3 includes one blade 301 at each of its front and rear ends. The blades 301 at the front and rear ends are symmetrically arranged in the front-rear direction so that after the blade 301 at the front end wears out, it can be reversed in the front-rear direction and installed for continued use, thereby improving the utilization rate and extending the service life.

[0032] like Figure 8 As shown, the back of the shovel 3 is provided with a corrugated groove, and a wavy blade 301 is formed at the tips of both ends.

[0033] like Figure 6 As shown, the back of the shovel 3, the A-side 201 of the back blade 2, and the bottom surface of the slot 103 of the shovel base 1 are parallel to each other, and the angle α between the back of the shovel 3 and the horizontal direction is 48°.

[0034] like Figure 7 As shown, the included angle β of the blade 301 of the shovel 3 is 44°.
