Description

Technical Field

[0001] The invention relates to the technical field of automatic extrusion demoulding of brittle materials, and in particular to a fully automatic closed extrusion demoulding device and method for brittle materials. Background Art

[0002] The extrusion demolding process is an important part of the discharging process of a certain material production process. The brittle material formed by crystallization adheres to the inner wall of the long cylindrical clamp pot. Physical extrusion is required to deform the clamp pot and then demold the brittle material inside the clamp pot, breaking it into block materials less than 50 mm. Due to the special properties of the material, the discharging process needs to be completed in an argon-protected glove box. The material is very brittle, and dust is easily generated during the extrusion process and overflows into the glove box, posing a risk of damage to the equipment in the box. The current extrusion demolding method is to manually take the clamp pot to the uniaxial extrusion device for manual rotary extrusion demolding. This method is inefficient, has a high risk of material overflow, and has high manual operation intensity. The defects and shortcomings are as follows:

[0003] 1. The extrusion stroke during the extrusion process is entirely controlled manually, which is highly random. This can easily lead to large randomness in the size of the material after demoulding, which can easily produce large-sized materials, which is not conducive to subsequent process operations. On the other hand, it can also easily cause damage to the tongs pot, increasing the risk of introducing inclusions into the product.

[0004] 2. The tongs pot during the extrusion process is not sealed, and the ultra-fine dust generated overflows into the glove box, causing damage to the equipment in the box;

[0005] 3. The demoulding effect of the bottom of the pot is poor, and the demoulding efficiency is low, and it needs to be knocked repeatedly by hand to ensure complete demoulding. Summary of the invention

[0006] The purpose of the present invention is to provide a fully automatic closed extrusion demolding device and method for brittle materials, so as to realize fully automatic closed extrusion demolding of brittle materials, effectively prevent brittle materials from overflowing into the glove box during the extrusion demolding process, and reduce the risk of damage to equipment in the box; ensure that the force on the clamp pot is uniform during the extrusion process, which can not only ensure the size after demolding but also effectively prevent the clamp pot from being broken and avoid the introduction of inclusions; knock out the residual material at the bottom of the clamp pot to improve the demolding efficiency and demolding effect of the material.

[0007] In order to achieve the above object, the present invention provides the following technical solutions:

[0008] A fully automatic closed extrusion demoulding device for brittle materials, comprising a device body, a rotary mechanism installed at the bottom of the device body, a clamp pot placed on the rotary mechanism, a guide bracket clamping mechanism installed at the top of the device body, a collecting tank installed on the guide bracket clamping mechanism, a lifting mechanism axially installed on the device body, a whole machine rotating mechanism installed on the back side of the device body, and an extrusion clamping mechanism installed on the device body;

[0009] The rotary mechanism is used to rotatably support the clamp pot to realize the axial rotation of the clamp pot; after the clamp pot is completely squeezed, the bottom of the clamp pot is knocked by an air hammer to knock out the residual materials in the clamp pot and drop them into the collection tank;

[0010] The extrusion jaw mechanism is located on both sides of the tongs pot, with adjustable pressure and stroke functions, and is used to evenly apply pressure to the tongs pot;

[0011] The guide bracket clamping mechanism is used to descend to dock with the clamp pot, turn the collection tank upside down on the top of the clamp pot, and clamp the clamp pot and the collection tank;

[0012] The lifting mechanism is used to drive the tongs pot to move upward a certain distance after the tongs pot completes one round of extrusion;

[0013] The whole machine rotation mechanism is used to control the whole device to rotate 180 degrees; dynamically adjust the initial extrusion position and posture of the clamp pot during the extrusion process.

[0014] As one of the feasible ways, the extrusion jaw mechanism uses a driving motor to drive a trapezoidal lead screw, so that the extrusion head on the trapezoidal lead screw applies pressure evenly to the tongs pot; the driving motor of the extrusion jaw mechanism uses a quick-change structure.

[0015] As one of the feasible ways, the guide bracket clamping mechanism adopts two sets of stainless steel cylinders to clamp the tongs pot and the collecting tank.

[0020] Step 3: After the tongs pot has completed one round of extrusion, the lifting mechanism drives the tongs pot to move upward a certain distance, and the extrusion claw mechanism extrudes the second round area of ​​the tongs pot;

[0021] Step 4, repeat steps 2 and 3 until all the clamp pots are extruded and demoulded, and then the whole device is rotated 180 degrees by the whole machine rotating mechanism, and the materials are collected in the collection tank;

[0022] Step 5: The air hammer of the rotary mechanism knocks the bottom of the tongs pot to knock out the remaining materials in the tongs pot and drop them into the collection tank.

[0023] As one of the feasible ways, in step 2, the rotating mechanism drives the tongs pot to rotate 30° each time to ensure uniform extrusion of the tongs pot; in step 3, after the tongs pot completes one circle of extrusion, the lifting mechanism drives the tongs pot to move upward the distance of an extrusion head.

[0024] The present invention also provides a fully automatic closed extrusion demoulding method for brittle materials, comprising the following steps:

[0028] Step 4: After the tongs pot has completed one round of extrusion, the lifting mechanism drives the tongs pot to move upward a certain distance, and the extrusion claw mechanism extrudes the second round area of ​​the tongs pot;

[0029] Step 5: Repeat steps 3 and 4 until all the parts of the clamp pot are squeezed. Then, the pneumatic hammer of the rotary mechanism knocks on the bottom of the clamp pot to knock out the remaining materials in the clamp pot and drop them into the collection tank.

[0030] As one of the feasible ways, in step 3, the rotary mechanism drives the tongs pot to rotate 30° each time to ensure uniform extrusion of the tongs pot; in step 4, after the tongs pot completes one round of extrusion, the lifting mechanism drives the tongs pot to move upward the distance of an extrusion head.

[0033] Step 2: The clamping claw mechanism squeezes the tongs pot. After one squeeze, the rotary mechanism drives the tongs pot to rotate once. Each rotation angle is the same to ensure that the tongs pot is squeezed evenly.

[0034] Step 3, after the tongs pot completes one round of extrusion, the lifting mechanism drives the tongs pot to move upward a certain distance, and the extrusion claw mechanism extrudes the second round area of ​​the tongs pot 7;

[0035] Step 4, repeating steps 2 and 3 until the upper part of the tongs pot is squeezed, the whole device is rotated 180 degrees by the whole machine rotating mechanism, and then repeating steps 2 and 3 to squeeze the lower part of the tongs pot;

[0036] Step 5: After all the positions of the clamp pot are squeezed, the air hammer of the rotary mechanism knocks on the bottom of the clamp pot to knock out the remaining materials in the clamp pot and drop them into the collection tank.
