Description

Technical Field

[0001] The utility model relates to the powder processing of diamond tool bits in the powder metallurgy process, and belongs to a part of the diamond tool bit powder flake filling process in the diamond tool bit sintering process. Diamond tool bit powder flakes need to be sintered before they can become hard diamond tool bits. By using an intelligently controlled graphite sheet mold loading and unloading elevator, the diamond tool bit powder flakes can be smoothly loaded into the graphite mold to complete the next sintering process. Background Art

[0002] The diamond blade powder itself is composed of diamond and matrix binder. The pre-pressed diamond blade powder needs to be sintered into a diamond blade under high temperature and high pressure sintering process conditions. The diamond blade is a superhard material, which is the working body of the diamond saw blade and plays the role of a cutting edge.

[0003] Before the sintering process of the diamond tool segment, the pressed diamond tool segment powder flakes need to be filled into a graphite mold, and then the diamond tool segment powder flakes can be sintered into a diamond tool segment.

[0004] In traditional processing technology, many diamond blade powder flakes are usually loaded into the graphite mold one by one by manual operation. Because the cavity of the graphite mold is deep and narrow, it is difficult to see clearly and put your hands in. It is not easy to accurately stack the diamond blade powder flakes in the deep and narrow graphite mold during loading. As a result, the loading speed is slow, the work efficiency is low, and it is easy to cause more diamond blade powder flakes to be damaged.

[0005] After adopting an intelligently controlled graphite sheet mold loading elevator, the ascending action of the loading elevator can be used to first fill more than half of the deep and narrow graphite mold space, reduce the depth, and leave a shallower graphite mold space to load the diamond segment powder flakes. Then, while loading the diamond segment powder flakes, the loading elevator is controlled to descend to make room and continue loading until the diamond segment powder flakes are completely loaded into the graphite mold.

[0006] However, a graphite sheet mold loading and unloading elevator previously used in this case had a low level of intelligence and used ordinary switches for simple lifting and lowering. The speed and displacement could not be controlled, and the specific speed and displacement position could not be displayed. The operation was difficult and labor-intensive, and the work efficiency was low. Summary of the invention

[0007] The utility model discloses an intelligently controlled graphite sheet mold loading and lifting machine, which is an intelligent transformation of a graphite sheet mold loading and lifting machine with ordinary lifting function. It uses the control of touch screen, PLC, servo electric cylinder intelligent components to realize the intelligent control upgrade of the entire loading and lifting machine, so that the lifting speed and displacement can be accurately controlled, and the speed and displacement status can be displayed in real time through the touch screen. It is characterized in that: an operation panel, touch screen, PLC, servo electric cylinder, dust removal fan assembly, lifting slider assembly are introduced and installed in the motion and control system of the intelligently controlled graphite sheet mold loading and lifting machine, and a positioning element is added. Intelligent control devices such as intelligent control touch screen, PLC, servo electric cylinder, etc. are used to realize the intelligent control of the lifting speed and displacement of the loading and lifting machine, and the speed and displacement information can be displayed in real time.

[0008] At the same time, a wind dust suction system is installed to effectively remove dust.

[0009] The addition of mold positioning blocks and positioning cylinders can further shorten the positioning time of the graphite sheet mold.

[0010] After the transformation, this intelligently controlled graphite sheet mold loading and lifting machine has the advantages of more reasonable structure, easy operation, high pushing efficiency and low cost. It provides reliable automatic conditions for the loading and processing of powder sheets, improves the loading efficiency and effectively reduces the labor intensity of manual labor.

[0011] The technical solution of this utility model:

[0012] It includes graphite mold, work surface, die loader lining, operation panel, electrical control cabinet, base, foot switch and other parts. The die loader lining is arranged on the bottom of the work surface, and a die loader push rod lifting device is added between the die loader lining and the base. The die loader push rod lifting device is composed of a lifting platform bottom plate, a servo electric cylinder, a lifting platform guide rod, a lifting platform slider, a push rod bottom plate and a locking nut. The lifting platform bottom plate is fixedly mounted on the base and the work surface through the lifting platform guide rod and the locking nut. The servo electric cylinder is fixedly mounted on the lifting platform bottom plate. The lifting platform slider on the top of the servo electric cylinder is sleeved on the lifting platform guide rod. The push rod bottom plate is fixed on the lifting platform slider, and a die loader push rod that can pass through the square through hole of the die loader lining is installed on the push rod bottom plate. The servo electric cylinder is automatically controlled by the operation panel and electrical control cabinet arranged between the base and the work surface.

[0013] Furthermore, a touch screen is arranged on the work surface, and the electrical control cabinet is composed of a PLC, a switching power supply, a servo driver, a contactor, a relay, an air switch, and a fuse, which together with the touch screen form an intelligent control circuit.

[0014] Furthermore, the operation panel is provided with an automatic / manual conversion switch, which can be controlled manually or automatically; in the manual control mode, the foot switch is the lifting power switch of the graphite sheet mold loading elevator. When working, the power of the switch is controlled by the foot to control the rise or fall of the servo electric cylinder in the mold pushing machine; in the automatic control mode, the intelligent control system enables the electric servo electric cylinder to automatically complete a series of actions set by the program according to the regulations, speed and displacement.

[0015] Furthermore, positioning blocks and positioning cylinders are added to the die loader liner to ensure that the graphite mold can be quickly placed in the correct position.

[0016] Furthermore, a dust removal device consisting of a fan motor, a dust removal cover and a pipeline is installed above the work surface.

[0017] The following functions are set on the touch screen:

[0018] In terms of action, touch operation keys for rising, pausing, descending and height zeroing are provided to operate the rising, descending, pausing and height zeroing actions of the mold loader push rod (6).

[0019] Functionally, there are step distance increase and decrease fine adjustment function operation keys for adjusting the distance of each step descent of the die loader push rod (6) during the automatic operation. The descent speed increase and decrease fine adjustment function operation keys are used to adjust the descent speed of the die loader push rod (6) during the automatic operation.

[0020] A call-up program key is provided. When a certain automatic process program that has been set is called, it can be run according to the process program. For example, in this case, the set-up process 1 is: delay 5 seconds—rise to the working position—delay 5 seconds—step down 20mm—delay 5 seconds—step down 20mm—delay 5 seconds—step down 20mm—delay 5 seconds—step down 20mm—delay 5 seconds—step down 20mm—delay 5 seconds—automatically stop.

[0021] From the display, it can show the current height, current step distance gradient, current speed value and currently running process program in real time.

[0022] The operation mode of an intelligently controlled graphite sheet mold loading and unloading machine can be flexibly switched. By using a manual / automatic switch, both the automatic mode and the manual mode can be selected.

[0023] When the automatic mode is selected, intelligent movement is realized. In this mode, the working program can be called for automatic operation, and the step gradient and speed size can be adjusted during work, and the real-time results after adjustment are displayed, and it runs according to the requirements of intelligent control.

[0024] When the manual mode is selected, simple mechanical operation can be performed. The lifting and lowering can be controlled by using the foot switch to achieve simple lifting and lowering actions.

[0025] Furthermore, some modifications were also made to the machine structure.

[0026] A dust removal device is installed in the mold loading elevator. The dust removal device includes a dust cover, a fan motor, and a fan, which can be opened or closed manually as needed. Due to the dust in the air at the powder tablet loading site, it is not good for the health of the operators. After installing the dust removal device, it is more conducive to health protection.

[0027] On the die loading plate of the die loading elevator, a positioning block and a positioning pin are newly installed on the side of the placement position of the graphite mold, which can save the positioning time when the graphite mold is placed.

DETAILED DESCRIPTION

[0040] As shown in the figure, the intelligently controlled graphite sheet mold loading and lifting machine includes a graphite mold 11, a work surface 14, a die loading device lining plate 7, an operation panel 15, an electrical control cabinet 16, a base 17, a foot switch 18 and other parts. The die loading device lining plate 7 is set on the bottom surface of the work surface 14, and a die loading device push rod 6 lifting device is added between the die loading device lining plate 7 and the base 17. The die loading device push rod 6 lifting device is composed of a lifting platform bottom plate 1, a servo electric cylinder 2, a lifting platform guide rod 3, a lifting platform slider 4, a push rod bottom plate 5 and a locking nut 9. The lifting platform base plate 1 is fixedly installed on the base 17 and the work surface 14 through the lifting platform guide rod 3 and the locking nut 9, the servo electric cylinder 2 is fixedly installed on the lifting platform base plate 1, the lifting platform slider 4 on the top of the servo electric cylinder 2 is sleeved on the lifting platform guide rod 3, the push rod base plate 5 is fixed on the lifting platform slider 4, and the mold loader push rod 6 that can pass through the square through hole of the mold loader lining plate 7 is installed on the push rod base plate 5, and the servo electric cylinder 2 is automatically controlled by the operation panel 15 and the electrical control cabinet 16 arranged between the base 17 and the work surface 14.

[0041] A touch screen 8 is arranged on the work surface 14 , and the electrical control cabinet 16 is composed of a PLC, a switching power supply, a servo driver, a contactor, a relay, an air switch, and a fuse, and together with the touch screen 8 forms an intelligent control circuit.

[0042] The operation panel 15 is provided with an automatic / manual conversion switch, which can be controlled manually or automatically. In the manual control mode, the foot switch (18) is the lifting power switch of the graphite sheet mold loading elevator. When working, the power of the switch is controlled by the foot to control the servo electric cylinder 2 in the mold pusher to rise or fall. In the automatic control mode, the intelligent control system enables the electric servo electric cylinder 2 to automatically complete a series of actions set by the program according to the specified speed and displacement.

[0043] A positioning block 10 and a positioning cylinder 19 are installed on the die loader liner 7 to ensure that the graphite mold 11 can be quickly placed in the correct position.

[0044] Above the work surface 14, a dust removal device consisting of a fan motor 12, a dust removal cover and a pipeline 13 is installed.

[0045] In order to realize the intelligent control of graphite sheet mold loading and lifting machine, touch screen, PLC and servo electric cylinder are introduced according to the required functions. According to the needs of graphite mold production and in line with the principle of simplicity and practicality, the control scheme is replanned.

[0046] In the power part, the original motor automatic telescopic rod is replaced with a servo electric cylinder to facilitate intelligent control.

[0047] In the control panel section, the control panel has been rearranged, such as Figure 2 The diagram shows the layout of the electrical switches. The intelligently controlled graphite sheet mold loading and unloading machine is designed with a control circuit. Figure 6 This is the general circuit diagram of the utility model. Since the load and power are small during the lifting movement of the intelligently controlled graphite sheet mold loading and unloading elevator, only 220v 50Hz AC power is required. In the main circuit, servo drive, and dust removal motor circuit, an air switch is used to control the circuit on and off and short circuit overload protection. Since the power of the fan motor is small, no other overload protection is used except the air switch, which simplifies the circuit.

[0048] Figure 6 In the circuit, the switch power supply is connected to the main circuit, the switch power supply provides 24V DC power, the PLC, touch screen, servo motor driver KA1 coil is connected to the control circuit, and HL is the indicator light. When the switch power supply is normal, turn on the SA1 switch and the control circuit is powered on. At this time, the fuse FU1 is used to protect the control circuit.

[0049] The specific operation process of the intelligently controlled graphite sheet mold loading and unloading elevator is: close the air switches QF1, QF2, and QF3, turn on the main switch, press the start button, the KM1 coil is energized, the KM1 main contact is closed, and the main circuit starts to be energized. Subsequently, turn on the SA1 switch, the control system starts to be energized, the PLC, touch screen, and servo motor driver KA1 coil are energized, the KA1 main contact is closed, and the servo driver is energized. After the main circuit starts to be energized, turn on the fan motor switch and the fan motor starts to work. When an abnormality occurs in the circuit, press the emergency stop switch, the main circuit is powered off, the control circuit is powered off, and the fan motor is also powered off. When a temporary stop is required, press the stop switch, and the main circuit, control circuit, and fan motor lose power.

[0050] Figure 7 As shown in the figure, the signals provided by the manual / automatic switch, lifting and origin displacement limit sensor, and foot switch are at the input end of the PLC. The output end of the PLC provides various output commands.

[0051] In the display part, a touch screen is added. According to the needs, the touch control keys and display scheme of the touch screen are designed. Figure 3 Shown is a schematic diagram of the functional layout of the touch screen of the present utility model.

[0052] The touch screen has action control, including rising, pausing, descending, height zeroing, automatic and manual touch operation keys, which are used to operate the rising, descending, pausing and height zeroing of the mold loader push rod 6.

[0053] There are function controls on the touch screen, with step distance increase and decrease fine-tuning, and descent speed increase and decrease fine-tuning function operation keys, which are used to adjust the gradient value of each step descent distance during the automatic operation of the mold loader push rod 6 and adjust the automatic operation speed of the mold loader push rod 6.

[0054] The touch screen has a display function. It can display the current step height value, current step distance gradient value, and current speed value in real time, so as to observe the real-time displacement, step distance, and speed status.

[0055] The touch screen has the function of calling the process program. The set process program can be called up as needed and can be used at any time, and the sequence number of the process program is displayed on the touch screen.

[0056] The mechanical structure of the machine was also modified at the same time.

[0057] First, a dust removal device is installed in the mold loading elevator. The dust removal device includes a dust cover, a fan motor, and a fan, which can be manually opened or closed as needed. Since there is a certain amount of dust at the powder tablet loading site, it is not good for the health of the operator. After installing the dust removal device, it is more beneficial to health.

[0058] Secondly, on the die loader liner of the die loader elevator, new positioning blocks and positioning pins are installed on the side of the placement position of the graphite mold, which can save the positioning time when placing the graphite mold. Because before the powder sheet is loaded, the loading mold also needs to be placed in the middle of the die loader liner accurately. Without a positioning device, it can only be based on feel, which is not conducive to positioning.

[0059] Now, the loading positioning block and positioning cylinder are installed, and the positioning diagram is as follows: Figure 5 The positioning block is a rectangular block, 5 mm higher than the die liner, and is fixed to the front end of the die liner by screws; the positioning cylinder is a cylindrical block, 5 mm higher than the die liner, and is fixed to the right end of the die liner. Figure 4 .
