Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of farm tool forging devices, and specifically, to a forging equipment and method for hardware farm tools. Background Art
[0002] Farm tools play a crucial role in agricultural production. They directly promote the development of agriculture by improving efficiency, reducing labor intensity, and improving soil conditions. The main functions of farm tools and their specific manifestations are as follows: 1. The use of farm tools significantly improves the efficiency of agricultural production. The popularization of iron farm tools further increases productivity and accelerates the large-scale development of agricultural production; 2. Farm tools such as rakes and plowshares can break up soil clods, level the land, improve soil aeration and water permeability, provide a better environment for crop growth, and can also remove weeds and pests, reducing competition and damage to crops; 3. The improvement of modern farm tools further reduces labor intensity, making agricultural production more efficient and user-friendly; 4. In different regions and environments, the design and use of farm tools have their own characteristics. The diversity and adaptability of farm tools enable them to meet the needs of different crops and tillage methods, promoting the diversified development of agriculture.
[0003] There are various production methods for modern farm tools, including mechanical processing, injection molding, stamping and other processes. For example, small farm tools such as sprayers and seeders are usually produced by injection molding and stamping processes; large farm tools such as tractors are completed through mechanical processing and assembly. Some farm tools are composed of multiple parts spliced together, and some farm tools are manufactured by forging. Farm tool forging refers to the process of manufacturing farm tools through forging technology. Forging is a metal processing technology that applies external force to a metal blank to cause plastic deformation, thereby obtaining parts or blanks with certain shapes, sizes and properties.
[0004] The existing forging equipment for farm tools has the following defects: 1. The upper die and the lower die of the existing forging equipment are mostly arranged in a vertical up-and-down manner. When loading materials, the metal materials are directly placed in the lower die, and forging is completed by the way of closing the die and extruding. However, for the vertically arranged upper die and lower die, during the loading process by the operator, it is very easy to cause danger due to operation errors; 2. Some farm tools need to heat the materials before forging. After the metal materials are heated, scale will be generated at their outer ends. During the forging process, the scale will fall off and stay between the upper die and the lower die. During the batch production process, due to the accumulated iron oxide flakes, it is very easy to cause concave holes at the outer ends of the forged hardware farm tools, affecting the production quality of farm tools; 3. After the heated metal material is forged, its temperature remains relatively high, and manual demoulding is required. This not only causes inconvenience in operation but also makes it extremely easy for the high-temperature metal to scald the staff.
[0005] Therefore, a forging equipment and method for hardware farm tools are proposed. The movable lower die facilitates feeding into its interior. At the same time, the scale between the upper die and the lower die is cleaned, and the lower die and the formed farm tool are ejected using a docking plate that can be ejected from the interior of the lower die to solve the above problems.

[0016] The operation method of the above-mentioned metal hardware forging equipment includes the following steps: Step 1: Material preparation, select pig iron with a moderate carbon content, put it into a charcoal burning furnace and heat it to orange-red to soften the metal. Step 2: Equipment adjustment, start the first servo motor. During this process, the bidirectional lead screw drives the connecting frame to move inside the forging box, and the lower die at the top of the assembly plate moves to the upper section position of the guide rail. Select molds of corresponding shapes and install the two groups of molds in the upper die and the lower die respectively, and heat the upper die and the lower die. Step 3: Forging and forming, put the heated pig iron material into the mold installed inside the lower die. At the same time, the first servo motor drives the bidirectional lead screw to rotate again, and the lower die at the top of the assembly plate moves towards the inside of the waste shell until the lower die moves to the lower section position of the guide rail. During this process, the forging cylinder drives the forging rod inside it to drive the upper die to press down, the upper die and the lower die are closed, and the pig iron is forged and formed. Step 4: Cleaning the scale, based on Step 1 and Step 3, during the heating process of the pig iron, scale is formed on its outer end.

Step 5: Dust removal, based on Step 4, during the process of closing the die, the airflow generated by the air pump flows inside the negative pressure pipe, causing negative pressure inside the negative pressure pipe, and the fallen dust enters the ash hopper for collection. Step 6: Demoulding, based on Step 3, after the pig iron is forged and formed, the upper die and the lower die are separated. Then, the first servo motor drives the bidirectional lead screw to rotate again. At this time, the assembly plate drives the hardware part formed inside the lower die to move to the upper section of the guide rail. During this process, the first wedge block abuts against the second wedge block, and the push rod connected to the second wedge block drives the docking plate at its top to lift, thereby ejecting the mold fixed at the top of the lower die and the hardware part from the inside of the lower die to complete demoulding.
[0017] The working principle and beneficial effects of the present invention are: 1. In the present invention, the assembly plate that can move between two sets of guide rails drives the lower die at its top to move inside the forging box. During the feeding process, the upper die and the lower die are in a displaced state, avoiding the problem of the equipment injuring the hands of the processing personnel due to improper operation by the processing personnel.
[0018] 2. In the present invention, the negative pressure generated by the air pump causes suction inside the forging box, so that during the forging process, the scale that falls off from the outer end of the pig iron quickly falls into the waste shell, and at the same time, the generated dust enters the ash hopper for collection, preventing the accumulated scale from affecting the forging quality of the farm tools and preventing the generated dust from polluting the environment.
[0019] 3. After the farm tool is forged in the present invention, the lower die moves to the upper position of the guide rail. At the same time, the first wedge block located at the lower end of the assembly plate abuts against the second wedge block, so that the docking plate clamped inside the lower die is jacked up, so that the die installed at the top of the docking plate and the formed farm tool are demolded from the lower die. While facilitating demolding, it avoids the phenomenon of scalding due to improper operation by the staff. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Embodiment 1 Refer to Figures 1 to 13 , which is the first embodiment of the present invention, and a forging and pressing device for hardware farm tools is proposed, including a forging and pressing box 1. Inside the forging and pressing box 1, a shielding shell 2 and a waste shell 3 are fixedly connected. On one side of the forging and pressing box 1, a mounting frame 4 is fixedly connected. Inside the mounting frame 4, a forging cylinder 5 is fixedly connected. Inside the forging cylinder 5, a forging rod 6 is movably connected. At the bottom end of the forging rod 6, an upper die 7 is fixedly connected. Inside the forging and pressing box 1, a feeding mechanism 8 is provided. The feeding mechanism 8 is arranged above the shielding shell 2 and the waste shell 3. Inside the waste shell 3 and outside the forging and pressing box 1, a cleaning mechanism 9 is provided. Inside the shielding shell 2 and at the bottom end of the feeding mechanism 8, an ejecting mechanism 10 is provided; The feeding mechanism 8 includes guide rails 801 symmetrically and fixedly connected to the side wall of the forging and pressing box 1. Between the two groups of guide rails 801, an assembly plate 802 is slidably connected. At the top end of the assembly plate 802, a lower die 803 is fixedly connected. In this embodiment, during the feeding and discharging processes, the assembly plate 802 drives the lower die 803 to slide between the two groups of guide rails 801, and at the same time, the upper die 7 and the lower die 803 are displaced, so as to facilitate feeding and discharging. During the feeding process, the upper die 7 and the lower die 803 are arranged in a displaced manner, preventing accidents caused by improper operation of the staff and improving the safety of farm tool forging. The cleaning mechanism 9 includes a leakage hole 9012 opened inside the lower die 803. Inside the waste shell 3, a filter plate 901 is fixedly connected. At the outer end of the forging and pressing box 1, a negative pressure pipe 909 is fixedly connected. The forging and pressing box 1 is communicated with the negative pressure pipe 909. At both ends of the negative pressure pipe 909, an air pump 9010 and an ash hopper 9011 are respectively fixedly connected. In this embodiment, scale will be generated at the outer end of pig iron after heating. During the forging process, the scale will fall off and accumulate inside the upper die 7 and the lower die 803, causing pits to appear at the outer end of the pig iron during forging, which affects the quality of agricultural tool forging. The generated scale falls into the interior of the waste shell 3 through the leakage hole 9012 inside the lower die 803. The filter plate 901 is provided to prevent parts from falling into the interior of the waste shell 3. At the same time, the air flow generated by the air pump 9010 makes the negative pressure pipe 909 and the forging box 1 connected thereto in a negative pressure state, so that the generated dust is quickly sucked into the interior of the waste shell 3, and the dust is collected in the ash hopper 9011 to prevent environmental pollution; The ejection mechanism 10 includes a docking plate 1001 clamped inside the lower die 803. Symmetrically fixed to the bottom end of the docking plate 1001 are abutting rods 1002 which are slidably connected between the abutting rods 1002 and the assembly plate 802. Fixed to the bottom end of the abutting rod 1002 is a first wedge block 1003, and a second wedge block 1006 is provided inside the shielding shell 2; In this embodiment, the temperature of the forged agricultural tool is still relatively high. At the same time, during the demolding process, it is necessary for workers to take out the agricultural tool from the lower die 803. It is difficult to demold and it is extremely easy to scald the hands. During the demolding process, the assembly plate 802 drives the lower die 803 to move to the upper section position of the guide rail 801. At this time, the first wedge block 1003 abuts against the second wedge block 1006, causing the abutting rod 1002 to drive the mold connected to the top end of the docking plate 1001 to lift, so that the agricultural tool is lifted from the interior of the lower die 803, facilitating the demolding operation of the agricultural tool; The guide rail 801 is divided into an upper section, a slope section and a lower section. The upper section and the lower section are arranged in parallel. The upper section of the guide rail 801 is arranged inside the shielding shell 2. The slope section of the guide rail 801 is arranged at the connection between the shielding shell 2 and the waste shell 3.

The set clamping rod 16 enables the connecting rod 804 to move in the moving groove of the assembly plate 802, thus facilitating the movement of the assembly plate 802 between the two sets of guide rails 801.
[0028] Embodiment 2 In this embodiment, an operation method of using the hardware farm tool forging equipment of Embodiment 1 is proposed. The operation method includes the following steps: Step 1: Material preparation. Select pig iron with a moderate carbon content, put it into a charcoal burning furnace and heat it to orange-red to soften the metal. The softened metal improves its plasticity and is quickly formed after being extruded by two sets of molds; Step 2: Adjust the equipment and start the first servo motor 8013. During this process, the bidirectional lead screw 808 drives the connecting frame 807 to move inside the forging box 1. The bidirectional lead screw 808 can drive the assembly plate 802 to reciprocate in the forging box 1, facilitating rapid feeding and demolding operations. Also, the lower die 803 at the top of the assembly plate 802 is moved to the upper section position of the guide rail 801. Then, select molds of corresponding shapes and install the two groups of molds in the upper die 7 and the lower die 803 respectively, and heat the upper die 7 and the lower die 803. The purpose of heating the upper die 7 and the lower die 803 is to make their temperatures uniform, effectively avoiding problems such as mold deformation and crack formation caused by temperature differences. At the same time, the molds are assembled and installed inside the upper die 7 and the lower die 803, which facilitates the replacement of the molds according to requirements; Step 3: Forging and forming. Put the heated pig iron material into the mold installed inside the lower die 803. At the same time, the first servo motor 8013 drives the bidirectional lead screw 808 to rotate again, and the lower die 803 at the top of the assembly plate 802 moves towards the inside of the waste shell 3 until the lower die 803 moves to the lower section position of the guide rail 801. During this process, the forging cylinder 5 drives the forging rod 6 inside it to drive the upper die 7 to press down, and the upper die 7 and the lower die 803 are closed for pig iron forging and forming. During forging, the upper die 7 and the lower die 803 are in a vertical state, improving the safety during the forging process of agricultural tools; Step 4: Clean the scale. Based on Steps 1 and 3, during the heating process of pig iron, scale is formed on its outer end. During the closing process of the upper die 7 and the lower die 803, the scale falls off. During this process, the fallen iron oxide flakes fall through the leakage holes 9012 inside the lower die 803 and land inside the waste shell 3 and on the top of the filter plate 901. During the forging process, some of the generated scale will automatically fall into the waste shell 3 through the leakage holes 9012, and the filter plate 901 can prevent parts from falling into the waste shell 3; Step 5: Dust removal. Based on Step 4, during the closing process, the airflow generated by the air pump 9010 flows inside the negative pressure pipe 909, making the inside of the negative pressure pipe 909 have a negative pressure, and the fallen dust is collected in the ash hopper 9011. During the forging process, the scale will generate shiny dust when being squeezed, and the dust is harmful to the environment and the staff. The airflow generated by the air pump 9010 makes the forging box 1 and the negative pressure pipe 909 have a negative pressure, making the dust quickly enter the ash hopper 9011; Step Six: Demoulding. Based on Step Three, after the pig iron is forged and formed, the upper die 7 is separated from the lower die 803. Subsequently, the first servo motor 8013 drives the bidirectional lead screw 808 to rotate again. At this time, the assembly plate 802 drives the hardware parts formed inside the lower die 803 to move to the upper section of the guide rail 801. During this process, the first wedge block 1003 abuts against the second wedge block 1006, and the push rod 1002 connected to the second wedge block 1006 drives the docking plate 1001 at its top to lift, thereby ejecting the fixed die and the hardware parts at the top of the lower die 803 from the inside of the lower die 803 to complete demoulding. After forging is completed, the assembly plate 802 moves until the end of the upper section of the guide rail 801. At this time, due to the abutment between the first wedge block 1003 and the second wedge block 1006, the push rod 1002 drives the die and the farm tool at the top of the docking plate 1001 to lift inside the lower die 803, realizing rapid demoulding and facilitating the removal of the farm tool.
