Abstract
Description
Technical Field
[0001] This utility model belongs to the field of stamping waste discharge technology, specifically relating to a waste guide. Background Technology
[0002] In the stamping process, due to various factors such as the sliding space of the blanking channel inside the mold and the stamping angle, the scrap will impact the inner wall of the channel at high speed. Due to the mutual restraint of the scrap and the adhesion of oil, the scrap will accumulate, making it difficult for the scrap to slide off.
[0003] In existing technology, a waste guide with an inclined surface is installed at the corresponding position of the discharge channel in the feeding channel to guide the waste. The waste impacts the inclined surface at high speed, and the inclined surface changes the movement path of the waste, causing the waste to fall faster. However, because the waste pieces discharged laterally or at a side angle will first collide with the inclined surface of the guide with one side, the side that collided is blocked and cannot continue to move, but the part of the waste piece away from the collision point will continue to move under the influence of inertia, thus causing the waste piece to flip over and flip towards the bottom inclined surface of the guide. After the waste piece makes large-area contact with the bottom surface of the guide, there is a possibility that residual oil on the bottom inclined surface of the guide will adhere to it and prevent it from falling smoothly, affecting the waste feeding effect, causing material to get stuck in the feeding hole, and affecting processing efficiency. Utility Model Content
[0004] This invention provides a waste guide that can restrict waste from turning over to the bottom surface of a high-strength insert, thereby improving the guiding effect on waste.
[0005] This utility model provides the following technical solution: a waste guide, comprising a guide body and a high-strength insert, wherein the bottom ends of the guide body and the high-strength insert are inclined; Several airflow guide holes are evenly opened in the guide body and the high-strength insert to increase the falling force of the waste and increase the resistance to the overturning of the waste. The bottom openings of the several airflow guide holes are radially distributed along the major axis of the elliptical inclined surface at the bottom of the high-strength insert, and the width of the bottom opening of the airflow guide holes gradually increases from the inside to the outside. The diversion chamber is detachably connected to the top of the guide body to disperse airflow into the guide airflow hole.
[0006] The guide body has a lower connecting groove on its side wall and an upper connecting groove on its side wall.
[0007] The high-strength insert has an upper connecting block fixedly connected to its top, the upper connecting block is inserted into the lower connecting groove, and the guide body is bolted to the upper connecting block.
[0008] The top of the diversion chamber is fixedly connected to a connecting pipe, which is connected to the diversion chamber.
[0009] The diversion chamber is filled with diversion cotton blocks.
[0010] The bottom of the diversion chamber is fixedly connected to a lower connecting block, which is inserted into the upper connecting groove. The guide body is bolted to the lower connecting block.
[0011] The top of the diversion compartment is fixedly connected to a mounting base, and a positioning pin is installed on the mounting base to fix the diversion compartment.
[0012] The beneficial effects of this invention are as follows: By utilizing the inclined surface at the bottom of the high-strength insert to guide the waste material downwards, and combining the synergistic effect of the guide airflow holes and the diversion chamber, vertically downward airflow can be discharged, further accelerating the descent of the waste material. Furthermore, the radially gradually widening of the guide airflow holes utilizes the wind force difference on both sides of the waste material to effectively limit its rotation towards the bottom surface of the high-strength insert, thereby preventing the waste material from adhering to the bottom surface of the high-strength insert and being contaminated by oil, ensuring that the waste material can be smoothly guided downwards. This not only significantly improves the guiding effect of the waste material but also enhances the smoothness of waste material discharge, ultimately improving the processing efficiency of the parts.
[0013] The parts of the device not covered herein are the same as or can be implemented using existing technologies. Attached Figure Description

[0016] Please see Figures 1-5The present invention provides the following technical solution: a waste guide, comprising a guide body 1 and a high-strength insert 2, wherein the bottom ends of the guide body 1 and the high-strength insert 2 are inclined.
[0017] Several guide airflow holes 3 are evenly opened in the guide body 1 and the high-strength insert 2 to increase the falling power of the waste and increase the resistance to the overturning of the waste. The bottom openings of the several guide airflow holes 3 are radially distributed along the major axis of the elliptical inclined surface at the bottom of the high-strength insert 2, and the width of the bottom opening of the guide airflow holes 3 gradually increases from the inside to the outside.
[0018] The diversion chamber 4 is detachably connected to the top of the guide body 1 to disperse the airflow and deliver it into the guide airflow hole 3.
[0019] In this implementation scheme: After the guide body 1 is aligned and installed with the high-strength insert 2 and the diversion chamber 4, it is connected by bolts. Then, the positioning pin 51 is installed in the corresponding hole of the mold. During actual installation, the angle between the mounting base 5 and the diversion chamber 4 is adjusted according to the opening position on the mold. The diversion chamber 4 and the mounting base 5 are fixed by welding, so that the bottom inclined surface of the guide body 1 and the high-strength insert 2 faces the discharge channel of the punching waste. The connecting pipe 41 is connected to the external air source pipe. The external air source delivers airflow to the diversion chamber 4 through the connecting pipe 41. After filtration and diversion, the airflow enters the guide airflow hole 3 and is then discharged through the lower opening of the guide airflow hole 3.
[0020] During the waste material guiding process, after being punched at high speed by a lateral or inclined punching die, the waste material splashes at high speed through the lateral or inclined waste material channel and collides with the bottom inclined surface of the high-strength insert 2. One side of the waste material first impacts the bottom inclined surface of the high-strength insert 2, and through the guidance of the inclined surface, some of its kinetic energy is converted into downward kinetic energy. Because one side of the waste material is obstructed and cannot continue to move, the side away from the side that collided with the inclined surface is not obstructed and will continue to move under the action of inertia, thus causing the waste material as a whole to flip over. The waste material tends to flip over towards the bottom inclined surface of the high-strength insert 2. During this process, the waste material is always subjected to the downward high-speed airflow discharged from the guide airflow hole 3, which exerts a downward force on the waste material as a whole, accelerating the fall of the waste material. Furthermore, the bottom opening of the airflow guide hole 3 gradually increases radially. The side of the waste material that collides experiences less wind force, while the side farther from the collision experiences more airflow and a greater force. This difference in force on both sides applies an acceleration in opposite directions to the waste material, thus limiting its rotation and preventing it from sticking to the bottom surface of the high-strength insert 2. Consequently, it avoids contact with oil stains on the bottom slope of the high-strength insert 2, preventing oil stains from adhering to it. Under the combined effects of gravity, kinetic energy converted from collision, and the force exerted by the airflow, the waste material falls downwards and is discharged from the mold, effectively improving the guiding effect and smoothness of waste discharge.
[0021] The beveled surface at the bottom of the guide body 1 has the same angle as the beveled surface at the bottom of the high-strength insert 2. At the junction of the beveled surface at the bottom of the high-strength insert 2 and the beveled surface at the bottom of the guide body 1, the edge of the high-strength insert 2 must not protrude beyond the edge of the beveled surface of the guide body 1 to avoid forming a step that could cause waste material to collide with and jam. Ideally, the edge of the high-strength insert 2 should be recessed by 0.1-0.2mm. This provides thermal compensation when the material expands due to high-temperature environments, preventing the edge of the high-strength insert 2 from protruding beyond the edge of the beveled surface of the guide body 1.
[0022] The guide body 1 has a lower connecting groove 11 and an upper connecting groove 12 on its side wall. The lower connecting groove 11 facilitates the connection between the guide body 1 and the high-strength insert 2, while the upper connecting groove 12 facilitates the connection between the diversion chamber 4 and the guide body 1. Furthermore, the lower connecting groove 11 and the upper connecting groove 12 provide a positioning effect, ensuring that after the guide body 1, the high-strength insert 2, and the diversion chamber 4 are aligned and installed, the bottom bevel of the high-strength insert 2 faces a predetermined angle.
[0023] The high-strength insert 2 has an upper connecting block 21 fixedly connected to its top. The upper connecting block 21 is inserted into the lower connecting groove 11, and the guide body 1 is bolted to the upper connecting block 21. The upper connecting block 21 facilitates the connection between the guide body 1 and the high-strength insert 2. During actual installation, the upper connecting block 21 is aligned and inserted into the lower connecting groove 11, and bolts are screwed into the threaded holes on the upper connecting block 21 and the guide body 1.
[0024] A connecting pipe 41 is fixedly connected to the top of the distribution chamber 4, and the connecting pipe 41 is connected to the distribution chamber 4. An external gas source can be connected by the connecting pipe 41. The connecting pipe of the external gas source is connected to the connecting pipe 41 through a connecting joint, and gas is delivered to the distribution chamber 4 through the connecting pipe 41.
[0025] The diversion chamber 4 is filled with diversion cotton blocks 42, which have a multi-pore structure. By setting the diversion cotton blocks 42, the airflow can be filtered to prevent impurities and debris from entering the guide airflow holes 3, and the multi-pore structure can disperse the airflow, so that the airflow is evenly delivered to multiple guide airflow holes 3.
[0026] A lower connecting block 43 is fixedly connected to the bottom of the diversion chamber 4. The lower connecting block 43 is inserted into the upper connecting groove 12, and the guide body 1 is bolted to the lower connecting block 43. The lower connecting block 43 facilitates the connection between the diversion chamber 4 and the guide body 1. In actual operation, the lower connecting block 43 is aligned and inserted into the upper connecting groove 12, and then a bolt is screwed into the threaded hole on the lower connecting block 43 and the guide body 1 for tightening.
[0027] A mounting base 5 is fixedly connected to the top of the diversion chamber 4, and a positioning pin 51 is installed on the mounting base 5 to fix the diversion chamber 4. By setting the mounting base 5 and the positioning pin 51, the entire device can be installed on the mold. Holes are opened on the mold to align with the positioning pin 51. After the positioning pin 51 is inserted into the corresponding hole, the bottom slope of the guide body 1 and the high-strength insert 2 faces the outlet of the waste discharge channel.
[0028] The working principle and usage process of this utility model: After the device is installed in a suitable position, the connecting pipe 41 is connected to the external air source pipe. The external air source supplies airflow to the diversion chamber 4 through the connecting pipe 41, and after filtration and diversion, it enters the guide airflow hole 3, and then is discharged through the lower opening of the guide airflow hole 3. The waste material splashes at high speed and collides with the bottom inclined surface of the high-strength insert 2. After one side of the waste material first hits the bottom inclined surface of the high-strength insert 2, through the guidance of the inclined surface, part of the kinetic energy is converted into downward kinetic energy. After the collision and flipping, the waste material is always subjected to the downward high-speed airflow discharged from the guide airflow hole 3, which exerts a downward force on the waste material as a whole, accelerating the fall of the waste material. The side of the waste material away from the collision receives more airflow and is subjected to a greater force. By applying an acceleration in opposite directions to the waste material through the difference in force on both sides, the tumbling of the waste material is restricted, preventing the waste material from sticking to the bottom surface of the high-strength insert 2, and thus preventing it from contacting the oil stains on the bottom slope of the high-strength insert 2. The waste material will fall downwards and be discharged from the mold under the combined action of gravity, collision conversion of kinetic energy and airflow.
