Technical Field

[0001] The utility model belongs to the technical field of electric porcelain production, and in particular relates to an automatic forming device for a straight-head bell-shaped electric porcelain blank. Background Art

[0002] Insulators are a kind of porcelain electrical insulating material, which is one of the main components of insulators. Insulators mainly act between conductors with different potentials or between conductors and grounding components, playing the role of electrical insulation and mechanical fixation, and have become an important supporting product in the national power grid. With the development of national economic construction, not only the demand for the quantity of insulators is increasing, but also higher requirements are put forward for its product quality. The molding quality of insulator blanks is an important factor that determines the performance of insulator products.

It not only has mature technology and rich experience, but also has a small investment, which is particularly suitable for small and medium-sized enterprises. Wet blank forming usually places the clay blank after extrusion forming in the blank repairing station, and uses special tools to cut and shape the clay blank according to the specified shape requirements. In the whole process, loading and fixing, tool changing, cutting, trimming and unloading are all manual operations, which not only has high labor intensity and low production efficiency, but also has large human errors, low processing accuracy and inconsistent product quality.

[0021] Compared with the prior art, the beneficial effects of the utility model are:

[0022] 1. Since the punching station and the spinning station are arranged on the frame from the back to the front, the punching station of the electric porcelain blank can punch the blank into a green sheet at the punching station, and then the lifting frame rises to drive the bracket to hold up the bottom mold of the electric porcelain blank, and the moving frame drives the green sheet to move to the spinning station. The lifting frame descends to fix the bottom mold of the electric porcelain blank on the spinning fixed seat, and the green sheet is spun at the spinning station, thereby realizing the mechanized and automatic forming of the electric porcelain blank, which not only saves manpower and material resources and improves production efficiency, but also can uniformly control the forming quality of the electric porcelain blank.

[0023] 2. Since the spinning station is provided with the initial spinning station and the final spinning station which are arranged closely from the back to the front, the insulator blank can be spun twice, which reduces the strength of the first spinning and can improve the forming quality of the insulator blank.

[0024] 3. A limit switch is provided to control the descending height of the spinning head, so that the descending height of the spinning head can be automatically controlled, which can avoid damage between the spinning head and the bottom mold due to excessive spinning, thus extending their service life; it can also unify the forming standards of the electric porcelain body and help improve its forming quality.

[0025] 4. Since the lower section of the support column in the limit switch is inserted into the through hole of the spinning fixed seat, an elastic body is arranged between the upper end and the spinning fixed seat, and a pressure sensor is arranged at the top of the support column, it not only simplifies the specific structure of the limit switch, but also indirectly uses the pressure signal as the switch signal of the limit, which can unify the density of the electric porcelain body and help further improve its molding quality.

[0026] 5. Since the spinning head is provided with a mud discharge hole, one end of the mud discharge hole is connected to the annular groove and the other end is connected to the outer wall of the spinning head, the residual mud produced by spinning can be discharged smoothly, further improving the molding quality.

[0027] 6. Since the lifting frame and the mobile frame are connected through matching slide rails and slide grooves, the moving direction of the mobile frame can be constrained, thereby facilitating the accurate transportation of the mobile frame between various workstations.

[0028] 7. Since the translation power mechanism adopts a structure in which a power rotation mechanism drives a gear rack, it is not only easy to implement, but also conducive to controlling the moving distance of the moving frame.

[0029] 8. Since the frame is also provided with an unloading station located in front of the spinning station, the unloading station is provided with an unloading fixed seat of the bottom mold of the electric porcelain blank, and the mobile frame can automatically push the spinning-formed electric porcelain blank to the unloading station, which is convenient for using a robot to transfer the formed electric porcelain blank.

[0030] 12. The utility model is cleverly designed. It uses initial extrusion followed by spinning, and the use of a movable frame is also conducive to maintaining the working temperature of the flame. It is worthy of promotion and use in the industry. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The working process of the utility model is as follows:

[0042] The bottom die 25 of the insulator body is fixed on the stamping base, and the mud section is placed on the bottom die 25 of the insulator body. The first cylinder 6 is controlled to descend, and the punching head 7 is driven to fall on the mud section. Under the joint action of the punching head 7 and the bottom die 25 of the insulator body, the mud section is preliminarily squeezed, and then the first cylinder 6 is reset, and the second cylinder 16 is controlled to extend, and the lifting frame 14 is driven to rise, so that the bracket on the moving frame 15 lifts the bottom die 25 of the insulator body. At this time, the servo motor 19 is started, and the moving frame 15 drives the bottom die 25 of the insulator body to reach the initial spinning station 3, and the moving frame 15 is stopped. Then the second cylinder 16 is reset, and the bottom die 25 of the insulator body is dropped and installed on the spinning base of the initial spinning station 3. The second motor 10 is started to drive the spinning head 11 to descend until the pressure sensor 23 reaches the specified value. The first motor 13 drives the spinning bottom die to rotate, and the insulator body 26 is preliminarily spun. During the spinning process, the residual mud is discharged from the mud discharge hole 20. The lifting frame 14 and the moving frame 15 are started again to deliver the preliminarily spun insulator 26 to the final spinning station 4, and the insulator 26 is spun into shape through the same working process as the preliminarily spinning station 3. The shaped insulator 26 is delivered to the unloading station 5 by the lifting frame 14 and the moving frame 15, and waits for the robot to transfer it away, and one insulator 26 is shaped.

[0043] When the insulator blank is in the state of being processed, the servo motor 19 can be reversed to send the bracket back to the rear station to complete the conveyance of the next insulator blank to the rear station.

[0044] In addition to using the above-mentioned screw 9 equipped with the second motor 10 as the lifting adjustment mechanism, the servo motor 19 can also be used to drive the sprocket chain to adjust the lifting. As long as the lifting adjustment can be achieved, there is no specific limitation on its structure. Similarly, the translational power mechanism is not limited to the above-mentioned gear 18 rack 17. Elastic bodies other than the compression spring 22 can also be used as long as elastic support can be achieved. The first lifting mechanism and the second lifting mechanism are not limited to the above-mentioned cylinder form, but the cylinder lifting speed is higher and the structure is simple.

[0045] The above is only the preferred embodiment of the utility model, and does not limit the utility model in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes.
