The working principle of the tool for manufacturing the gasket of the embodiment of the invention is as follows:
Firstly, the second component 2 is placed in the first component 1, the upper end 201 of the second component is positioned in the first groove 103, the lower end 202 of the second component is positioned in the first through hole 104, the ejector rod 301 of the third component 3 is inserted into the second through hole 203, then the first component 1 is fixedly connected with the second component 2, and the first component 1, the second component 2 and the third component 3 are assembled, because the upper end 201 of the second component and the lower end 202 of the second component are respectively in clearance fit with the first groove 103 and the first through hole 104 of the first component 1, and the axes of the first through hole 104 and the second through hole 203 coincide, the second through hole 203 is in clearance fit with the first ejector rod 301, so that the second component 2 slides up and down along the first ejector rod 301, and no front-back left-right (transverse) shaking occurs; placing a raw material plate such as an asbestos plate 100 or the like for making a gasket on the fourth member 4 so that the upper end surface 4011 of the second ejector rod is in contact with the lower surface of the raw material plate such as the asbestos plate 100; the assembled first member 1, second member 2 and third member 3 are placed on the upper surface of a raw material plate such as asbestos plate 100 with the horizontal lower end face 2021 of the lower end of the second member in contact with the upper surface of the raw material plate such as asbestos plate 100 and with the lower end face 2021 of the lower end of the second member located directly above the upper end face 4011 of the second ejector rod, a downward force is applied to the first member 1 and third member 3 to move them downward, then the first ejector rod 301 has a tendency to slide toward the third through hole 402, a portion of the raw material plate such as asbestos plate 100 corresponding to the third through hole 402 is pushed to have a downward tendency, and the second ejector rod 401 having a horizontal upper end face 4011 applies an upward push to the raw material plate such as asbestos plate 100, so that a portion of the raw material plate such as asbestos plate 100 in contact with the horizontal lower end face 2021 of the lower end of the second ejector rod 401 and the second member has a upward tendency to move upward, as shown in fig. 2, and then a broken portion of the raw material plate such as asbestos plate 4011 is formed by the gasket. Because the second through hole 203 of the second component 2 is in clearance fit with the first ejector rod 301, the second ejector rod 401 is in clearance fit with the first through hole 104, the first ejector rod 301 is in clearance fit with the third through hole 402, and the axes of the first through hole 104, the second through hole 203 and the third through hole 402 coincide, and because the first guide structure is matched with the second guide structure, each gasket manufactured by the tool for manufacturing gaskets in the embodiment is a gasket with concentric inner and outer diameters, and the defective rate of the gasket is reduced.
On the basis of the tool for manufacturing the gasket, the structure of the tool for manufacturing the gasket is improved, and the tool is concretely as follows:
Referring to fig. 3, fig. 3 is a schematic view of another tool for manufacturing a gasket according to an embodiment of the invention. As shown in fig. 3, the tool for manufacturing a gasket of the present embodiment may further include: the first elastic member 5 provided in the first groove 103, and both ends of the first elastic member 5 are in contact with the upper end surface 2011 of the upper end of the second member and the lower surface 302 of the third member. The first elastic member 5 may be a coil spring. In order to ensure that the part of the raw material plate, such as the asbestos plate, cut into the gasket is uniformly stressed, the number of the first elastic components 5, such as the spiral springs, can be two, the two first elastic components 5, such as the spiral springs, are arranged opposite to the lower end 202 of the second component, or more than two first elastic components can be uniformly distributed on the upper end face of the upper end of the second component, for example, 3 or 4 first elastic components are uniformly distributed on the upper end face of the upper end of the second component. When the second ejector 401 applies upward thrust to the third member 3 to move upward, the first elastic member 5 applies downward pressure to the third member 3 to prevent the third member 3 from moving upward, so as to ensure that the tool for manufacturing the gasket can cut the gasket smoothly.
As shown in fig. 3, the fourth member 4 further has a base 404, and the second jack 401 is provided on the base 404. The tool for manufacturing a gasket of the present embodiment may further include: a sixth member 6 located below the first member 1, the sixth member 6 having an upper end face 601 of the sixth member abutting against a lower end face 1021 of a lower end 102 of the first member, a lower end face 602 of the sixth member, and a fifth through hole 603 having an axis coincident with an axis of the first through hole 104 and in clearance fit with the second jack 401; and a second elastic member 7, wherein the second elastic member 7 abuts against the lower end surface 602 of the sixth member and the base 404. The number of the second elastic members 7 may be 3 or more, and 3 or more second elastic members 7 are uniformly distributed around the second jack 401. As shown in fig. 3, when the first member 1 applies a downward force to the sixth member 6, the second elastic member 7 applies an upward force to the sixth member 6, so that the upper end face 601 of the sixth member abuts against the lower end face 1021 of the lower end of the first member, and both form a firm grip on a portion of the raw material plate other than the outer diameter of the gasket, such as an asbestos plate, facilitating cutting of the gasket.
With continued reference to fig. 3, the tool further includes: an eighth member 8, the eighth member 8 having an upper end 801 connected to a slide of the forging machine tool and a lower end 802 connected to the first member 1 of the eighth member, and a ninth member 9, the ninth member 9 for connecting the sixth member 6 and a base of the forging machine tool, the ninth member 9 having a seventh through hole 901 communicating with the third through hole 402; the base of the forging machine tool has a discharge hole communicating with the seventh through hole 901. The upper end 801 of the eighth component is a cylinder and is clamped with the slide block of the forging machine through a fastening component such as a bolt, and the upper end of the eighth component can also be provided with a positioning groove, so that the fastening component such as the bolt can firmly clamp the eighth component 8 on the slide block of the forging machine. The eighth component 8, the third component 3, the first component 1, the second component 2 and the first elastic component 5 are driven to move up and down by the up and down movement of the slide block of the forging machine tool. The ninth member 9 may be mounted on the base of the forging machine by fastening members such as bolts, and the sixth member is fixedly coupled to the ninth member by bolts, and the raw material plate such as the asbestos plate 100 cut by the first ejector 301 is discharged from the discharge hole through the seventh through-hole 901 from the third through-hole 402.
The tool for manufacturing the gasket of the present embodiment is suitable for manufacturing gaskets for sealing the connection between the pressure gauge and the connecting pipeline of the equipment, and other types of gaskets having inner holes.
The raw material plate for manufacturing the gasket can be asbestos plate, thin metal plate, hard plastic plate and the like.
Next, the structure of each component of the tool for manufacturing a gasket according to the present embodiment will be described in detail.
Referring to fig. 4 and 5 for the structure of the first component, fig. 4 is a schematic diagram of the first component in a tool for manufacturing a gasket according to an embodiment of the present invention; fig. 5 is a cross-sectional view of fig. 4 taken along the direction B-B. As shown in fig. 4, the cross section of the third part 3 may be circular; the cross section of the first groove 103 may be circular; the cross section of the first through hole 104 is circular, and the first through hole 104 and the first through hole are coaxial, so that the shapes of the first groove 103 and the first through hole 104 are cylindrical. As shown in fig. 4 and 5, the lateral dimension of the first groove 103 is larger than the lateral dimension of the first through hole 104. It will be appreciated by those skilled in the art that the cross-section of the first recess may also be rectangular, square, oval or triangular in shape, and that the present invention may be implemented without being coaxial with the first through hole.
In fig. 4, the lateral dimensions of the first groove 103 are a distance from the uppermost end to the lowermost end of the first groove 103 and a distance from the leftmost end to the rightmost end. In fig. 5, the "lateral dimensions of the first groove" are the distance from the front end to the rear end of the first groove 103 and the distance from the left end to the right end. Accordingly, in fig. 4, the lateral dimensions of the first through hole 104 are the uppermost to lowermost distance and the leftmost to rightmost distance of the first through hole 104. In fig. 5, the "lateral dimensions of the first through-hole" are the distance from the extreme front to the extreme rear of the first through-hole 104 and the distance from the extreme left to the extreme right.
The first component may also have a first guide structure. The purpose of the first guide structure is to make the first through hole correspond exactly to the second ejector pin of the fourth part. As shown in fig. 4, the first guide structure may be a fourth hole 105. The number of the fourth holes 105 is two, and the fourth holes are disposed opposite to the first through holes 104. How the fourth holes are positioned to the first and fourth members will be described in detail below when the fourth member is introduced.
In fig. 4 and 5, the third part 3 is also provided with 3 threaded holes X for engagement with bolts for threaded connection with the third part. The function of the threaded hole will be described in detail below when the third component is presented.
For the structure of the second component, please refer to fig. 6 and 7, wherein fig. 6 is a schematic diagram of the second component in a tool for manufacturing a gasket according to an embodiment of the present invention, and fig. 7 is a cross-sectional view along C-C of fig. 6. As shown in fig. 6 and 7, the lateral dimension of the upper end 201 of the second member is greater than the lateral dimension of the lower end 202 of the second member.
