A valve seat ring press material handling device

Abstract

This invention provides a valve seat ring press material handling device, including a press panel with a mold cavity. The press panel surface also features a powder filling mechanism and a material handling mechanism with their movement trajectories perpendicular to each other in space. The powder filling mechanism includes a horizontally sliding left and right material shoes arranged opposite each other. The material handling mechanism has a downward-sloping slide at its bottom and includes a servo drive assembly and a material handling arm. The material handling arm is rigidly connected to the servo drive assembly, and its telescopic end has a material handling hook. When the servo drive assembly drives the material handling arm to extend to one side of the mold cavity, the right material shoe pushes the product to be handled into the material handling hook, and the material handling arm retracts, causing the product to fall into the slide. Based on the space-constrained press panel, the powder filling mechanism and the material handling mechanism are arranged perpendicularly to each other in space. By utilizing the precise alignment of the material handling arm's retraction trajectory with the slide entrance, automatic product handling is achieved, avoiding manual intervention and ensuring continuous press production.

Description

Technical Field

[0001] This utility model relates to the field of valve seat manufacturing technology, and in particular to a valve seat press material handling device. Background Technology

[0002] Valve seat rings are a key component of the engine valve assembly. Their common manufacturing process is powder metallurgy forming—by pressing and sintering metal powder to obtain a blank that meets dimensional and performance requirements. The core function of a servo-controlled powder feeder is to precisely feed metal powder into the mold cavity and control the pressure and displacement through a servo system to complete the compaction and forming of the powder.

[0003] Traditional left-right servo powder feeding presses use alternating left and right feed shoes to complete the powder filling and pushing actions. However, due to limitations in equipment space layout and action sequence, such presses often encounter the problem of being unable to unload material after product pressing. This is because the left and right feed shoes are designed to move linearly along the front-back direction of the press panel (i.e., the width direction of the press panel), while the product unloading position is located at the front of the press. Therefore, the feed shoes themselves occupy the path space for the product to move forward, preventing the product from being pushed to the corresponding slide at the front of the press, thus hindering automatic material unloading. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a valve seat ring press material handling device, including a press panel, the press panel having a mold cavity, and the surface of the press panel also having a powder filling mechanism and a material handling mechanism whose motion trajectories are perpendicular to each other in space. The powder filling mechanism includes a left and right material shoe that are horizontally sliding relative to each other; The bottom of the material handling mechanism is provided with a downward-sloping slide. The material handling mechanism includes a servo drive component and a material handling arm. The material handling arm is rigidly connected to the servo drive component. The telescopic end of the material handling arm is provided with a material handling hook. When the servo drive component drives the material handling arm to extend to one side of the mold cavity, the right material shoe pushes the product to be picked up into the material handling hook. The material handling arm retracts, causing the product to be picked up to move and fall into the slide.

[0005] Furthermore, the powder filling mechanism slides horizontally along the length direction of the press panel; the material taking mechanism extends and retracts horizontally along the width direction of the press panel.

[0006] Furthermore, the servo drive assembly includes an electric cylinder and a servo motor, the side wall of the electric cylinder is provided with a slide rail, and the material handling arm is connected to the slide rail through a connecting plate.

[0007] Furthermore, the electric cylinder is fixedly connected to the edge of the press panel via a tripod.

[0008] Preferably, the material-picking hook is detachably connected to the material-picking arm.

[0009] Furthermore, the slide is located directly below the material handling arm, and one end of the slide is fixedly connected to the edge of the press panel.

[0010] Furthermore, the left and right material shoes are symmetrically distributed about the mold cavity.

[0011] Furthermore, a press that can be raised and lowered is provided directly above the mold cavity.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This utility model is based on the space-constrained press panel, which arranges the powder filling mechanism and the material picking mechanism perpendicular to each other in the space. By utilizing the precise docking of the material picking arm retraction trajectory with the slide inlet, the automatic material picking of products can be realized, avoiding manual intervention and ensuring continuous production of the press.

Detailed Implementation

[0015] To make the technical solutions and effects of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0016] The present invention aims to provide a material handling device for a valve seat press, which solves the problem of limited panel area and left and right material shoes in the existing press, and enables automatic material handling of products.

[0017] Please see Figure 1-2 The system mainly includes a press panel 000, with a mold cavity 001 at its center and a press that can be raised and lowered positioned directly above the mold cavity 001. The press panel 000 also has a powder filling mechanism 100 and a material taking mechanism 200 arranged on its surface with their movement trajectories perpendicular to each other in space. Furthermore, the powder filling mechanism 100 can slide horizontally along the length of the press panel 000; the material taking mechanism 200 can extend and retract horizontally along the width of the press panel 000.

[0018] The powder filling mechanism 100 includes a horizontally sliding left shoe 110 and a right shoe 120 that are positioned opposite each other. The left shoe 110 and the right shoe 120 are symmetrically distributed about the mold cavity 001. Since the left and right servo powder feeding presses use the left and right shoe shoes to alternately complete the powder filling and pushing actions, which is a conventional technology in this field, it will not be described in detail here. Furthermore, to better illustrate the position and structure of the material handling mechanism 200, a supplementary diagram is attached. Figure 1-2 The specific structures of the left material shoe 110 and the right material shoe 120 are omitted.

[0019] The material handling mechanism 200 in this embodiment will be described in detail below.

[0020] The material handling mechanism 200 includes a servo drive assembly 210 and a material handling arm 220. The material handling arm 220 is rigidly connected to the servo drive assembly 210, and the telescopic end of the material handling arm 220 is provided with a material handling hook 221.

[0021] The material-retrieving hook 221 is detachably connected to the material-retrieving arm 220. Optionally, the material-retrieving hook 221 can be a single hook or a double hook to adapt to the production needs of the press.

[0022] The servo drive assembly 210 includes an electric cylinder 211 and a servo motor 212. The side wall of the electric cylinder 211 is provided with a slide rail 213, and the material handling arm 220 is connected to the slide rail 213 through a connecting plate 214. The electric cylinder 211 is fixedly connected to the edge of the press panel 000 through a tripod 215 and bolts.

[0023] In a further embodiment, the bottom of the material handling mechanism 200 is provided with a downwardly inclined slide 230. Preferably, the slide 230 is located directly below the material handling arm 220. One end of the slide 230 is fixedly connected to the edge of the press panel 000.

[0024] When the servo drive assembly 210 drives the picking arm 220 to extend to one side of the mold cavity 001, the right shoe 120 pushes the product to be picked into the picking hook 221, and the picking arm 220 retracts, causing the product to be picked to move and fall into the slide 230, thus completing the automatic picking action.

[0025] Please see Figure 3-5 The operation process of the material handling mechanism 200 includes: Step 1: Extend the material handling arm 220 to the material handling position.

[0026] The second step is to push the product into the material hook 221 using the right material shoe.

[0027] The third step is to retract the material arm 220 and move the product into the slide.

[0028] It should be noted that when the left feed shoe finishes filling with powder and retracts, the mold begins pressing, and the material handling arm 220 advances to the material handling position. After the product is pressed into shape, the right feed shoe begins to advance to prepare for filling with powder, while simultaneously pushing the product into the material handling hook 221. After filling with powder, the right feed shoe begins to prepare to retract. At the same time, the material handling arm 220 begins to retract to the waiting position, and removes the product.

[0029] The right material shoe retracts and the material taking arm 220 retracts simultaneously, without affecting the press's production cycle. Only when the right material shoe retracts to the starting position does the left material shoe begin to slide forward, and at this time the material taking arm 220 also retracts to the waiting position.

[0030] In this embodiment, the material picking servo action is controlled by the press angle curve. For example, if the product pressing demolding position is 245-265°, then when the press runs to 245°, the material picking servo starts to move forward to the material picking position; when it runs to 270°, the material picking servo starts to retreat to the waiting position, thereby preventing the left material shoe from colliding with the material picking servo.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
