Abstract
Description
Technical Field
[0001] This utility model relates to a technology in the field of porcelain insulator processing, specifically a tooling for forming suspension porcelain insulator blanks. Background Technology
[0002] In the molding and manufacturing process of suspension porcelain insulator blanks, the blanks need to be positioned and fixed to facilitate the shaping of the insulator's shape. The existing fixing method is manual fixation, which is inefficient and requires highly skilled workers. Otherwise, the blanks are prone to tilting during the molding process, resulting in poor product dimensions and reduced quality.
[0003] In order to solve the above-mentioned problems existing in the prior art, this utility model is thus developed. Utility Model Content
[0004] To address the aforementioned shortcomings of existing technologies, this invention proposes a suspension porcelain insulator blank forming fixture that can fix the clay blank, ensuring its stability during the blanking process and preventing dimensional defects and scrap caused by instability.
[0005] This utility model relates to a molding fixture for a suspension porcelain insulator blank, comprising: a blank suction assembly and a pair of blank trimming tools arranged symmetrically relative to the blank suction assembly;
[0006] The billet suction assembly includes a billet suction limiting fixture and a rotating seat arranged vertically; the billet suction limiting fixture has an air vent along the central axis, and the rotating seat has an air vent; the billet suction limiting fixture is fixed on the rotating seat, and the air vent communicates with the air vent; the rotating seat is set in a sealed cavity, and a vacuum pumping device is also provided corresponding to the air vent.
[0007] In some specific implementation schemes, the rotating seat is driven to rotate by a direct drive motor or a stepper motor.
[0008] In some specific implementation schemes, the blank suction limiting fixture is provided with umbrella ridge limiting baffles corresponding to the umbrella ridges of the suspension porcelain insulator, and the corresponding umbrella ridges are limited by several pairs of baffles.
[0009] In some specific implementation schemes, the trimming tool is mounted on a linear displacement mechanism, which drives the tool to feed and retract.
[0010] For some specific implementation schemes, the molding fixture is equipped with a negative pressure gauge to monitor the air pressure in the sealed cavity; this allows the motor to be started and the suction assembly to rotate with the clay blank after the vacuum device operates and the air pressure in the sealed cavity reaches the preset requirement.
[0011] Compared with the prior art, the present invention has the following technical effects:
[0012] On the one hand, the blank is kept fixed by the suction component during the rotating blanking process, replacing manual holding and fixing; on the other hand, the blanking cutter cuts the blank at symmetrical positions, reducing the probability of the blank becoming unstable due to changes in the center of gravity, thereby improving the blanking efficiency of the suspension porcelain insulator blank and ensuring the product yield.

Detailed Implementation
[0017] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0018] Example 1
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment includes: a blank suction assembly 100 and a pair of blank trimming tools (not shown in the figure) arranged symmetrically with respect to the blank suction assembly 100.
[0020] The blank suction assembly 100 includes a blank suction limiting fixture 101 and a rotating seat 102 arranged vertically; the blank suction limiting fixture 101 has a vent 103 along its central axis, and the rotating seat 102 has a plurality of vent holes 104 in the circumferential direction; the blank suction limiting fixture 101 is fixed on the rotating seat 102, and the vent holes 104 are connected to the vent 103.
[0021] The blank suction limiting fixture 101 is provided with an umbrella ridge limiting baffle 105 corresponding to the umbrella ridge of the suspension porcelain insulator, such as Figure 3 As shown, four pairs are preferably provided and evenly distributed around the circumference; these four pairs of baffles restrict the corresponding umbrella ribs between the paired baffles.
[0022] A rotating seat 102 is disposed in the sealed cavity 200 and is driven to rotate by a stepper motor. A vacuum device (not shown in the attached diagram) is also provided corresponding to the vent 104 on the rotating seat 102. The vacuum device draws air from the sealed cavity 200, adsorbing and fixing the clay blank 300 placed on the suction limiting fixture 101. In addition, a negative pressure gauge is provided to monitor the air pressure in the sealed cavity 200; this allows the motor to be started and the suction assembly to rotate with the clay blank after the air pressure in the sealed cavity 200 reaches the preset requirement through the operation of the vacuum device.
[0023] The trimming tool is mounted on the linear displacement mechanism 400, which includes a horizontal displacement mechanism 401 and a vertical displacement mechanism 402, to facilitate trimming of different types of suspension insulator blanks. The trimming tool is mounted on the displacement output end of the horizontal displacement mechanism 401, and the horizontal displacement mechanism 401 is mounted on the displacement output end of the vertical displacement mechanism 402.
[0024] In this embodiment, during operation, the clay blank 300 is placed on the suction limiting fixture 101, and the vacuum device is turned on to evacuate the sealed cavity 200 until the negative pressure gauge shows that the air pressure reaches the preset value. Then, the motor is turned on to drive the rotating seat to rotate, and the clay blank rotates accordingly. Then, the trimming tool is driven by the linear displacement mechanism to advance and cut the clay blank until the trimming is completed, and a shaped blank is obtained. Finally, the trimming tool is retracted under the drive of the linear displacement mechanism, the rotating seat drive motor and the vacuum device are turned off, and the shaped blank is removed.
[0025] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
