A box-type tempering furnace feeding and transporting system and tempering furnace control method

Abstract

The invention discloses a box-type tempering furnace feeding and transportation system and a tempering furnace control method. The structure comprises a tempering furnace, a lifting frame, an isolation door, a placing frame, a clamping frame, a horizontal path and a vertical path. The lifting frame is fixed to the outer surface of the tempering furnace. The clamping frame comprises a clamping head, a swivel, a support shaft, a mounting frame, a movable rod, a drag rod, a turntable and a fixed seat. The swivel is installed between the clamping head and the drag rod. When the clamping head clamps the material, its elastic body is in an extruded state. The pressure frame drives the movable body to retract along the gap between the clamping teeth, so that the clamping teeth are exposed to clamp the material. After the material is unloaded, its elastic body will support the pressure frame and the movable body back to the original position. The movable body will remove the impurities and debris stuck between the clamping teeth along the gap between the clamping teeth during the movement, so as to prevent the impurities from agglomerating between the gap between the clamping teeth, thereby affecting the fit and stability of subsequent clamping.

Description

Technical Field

[0001] The invention belongs to the field of metal processing, and more specifically, particularly relates to a box-type tempering furnace feeding and transportation system and a tempering furnace control method. Background Art

[0002] The feeding and transportation of the tempering furnace is a key link in the heat treatment process. It has functions such as automatic furnace entry and exit and temperature control. In the process of metal materials entering and exiting the furnace, it is mainly composed of conveying rails, conveying racks, feeding systems and control systems. The feeding and transportation system realizes the functions of continuous operation and rapid material loading and unloading, and improves production efficiency and quality stability.

[0003] Based on the above findings, the existing tempering furnace feeding and transportation device has the following main shortcomings, such as:

[0004] When the tempered material is clamped and conveyed, in order to clamp the material more stably and increase the friction between the clamp and the material, the clamp has a concave and convex surface. There will be impurities integrated on the surface of the material that has been treated at high temperature. When the clamp is clamped, the impurities are easily adhered to the gap of the clamp and then agglomerated on the surface, affecting the stability and stability of the contact between the clamp and the material.

[0005] Therefore, it is necessary to propose a box-type tempering furnace feeding and transportation system and a tempering furnace control method. Summary of the invention

[0006] In order to solve the above technical problems, the purpose and effect of a box-type tempering furnace feeding and transportation system and a tempering furnace control method of the present invention are achieved by the following specific technical means:

[0007] Its structure includes a tempering furnace, a lifting frame, an isolation door, a placing frame, a clamping frame, a transverse track, and a vertical track. The lifting frame is fixed to the outer surface of the tempering furnace, the isolation door is installed in the lifting frame track to move up and down, the placing frame is installed on the vertical track to move, and the clamping frame is installed on the transverse track to move;

[0008] The clamping frame includes a clamping head, a swivel, a support shaft, a mounting frame, a movable rod, a towing rod, a turntable, and a fixed seat. The swivel is installed between the clamping head and the towing rod. The support shaft supports the towing rod and is fixed to the inner side of the mounting frame. The upper end of the movable rod is connected to the towing rod and can swing. The lower end of the movable rod is fixed to the outer surface of the fixed seat. The turntable is installed between the mounting frame and the fixed seat.

[0009] The clamping head comprises a movable plate, an adjustment slot, a pendulum body, and a main clamping body, wherein the movable plate is connected to the main clamping body, the main clamping body is assembled in the adjustment slot for movement and adjustment, and the pendulum body is fixed to the outer surface of the adjustment slot;

[0010] The movable plate includes a fixed plate, a resilient body, a pressure frame, groove patterns, a movable body, and clamping teeth. The resilient body is installed between the pressure frame and the fixed plate. The upper and lower ends of the movable body are fixed to the pressure frame. The movable body and the clamping teeth are complementary to each other. The groove patterns and the pressure frame are an integrated structure. The support shaft supports the axis point where the fixed drag rod swings.

[0011] As a further improvement of the present invention, the horizontal track and the vertical track are perpendicular to each other, the isolation door moves to the lowest point to separate the tempering furnace from the space outside, the placement rack carries the materials and moves back and forth along the vertical track, and the tempering furnace is a box-type structure, and multiple ones can be installed side by side as needed to operate simultaneously.

[0012] As a further improvement of the present invention, the turntable can control the overall rotation of the mounting frame, the swivel can control the rotation of the clamping head, the telescopic movement of the movable rod controls the swing angle of the drag rod, the fixed seat is divided into upper and lower parts, the upper part can rotate with the turntable, the movable rod is installed at a position near the tail of the drag rod to assist in the balance of the overall clamping of objects, and a power control group is installed inside the drag rod to control the overall power activity, and the clamping head moves to the left and right sides by power to adjust the clamping range of the material, and can perform tight clamping according to the size of the material.

[0013] As a further improvement of the present invention, the two resilient bodies are a group of symmetrical structures and have a rebound support effect. The movable bodies are provided with four and cooperate with the gap between the clamping teeth. The groove pattern and the pressure frame form a concave and convex surface to increase the contact friction. When the movable body is in a stationary state, the outer side surface protrudes more than the clamping teeth. When the pressure frame contacts the material, it will drive the movable body to be squeezed in the direction of the fixed plate, thereby shrinking in the gap between the clamping teeth, so that the clamping teeth can expose the body and contact and clamp the material.

[0014] As a further improvement of the present invention, the placement rack includes a top column, an arc surface, a bottom plate, and a control box. The arc surface is fixed to the upper surface of the bottom plate, the control box is connected to the bottom plate, the top column passes through the arc surface and is fixed to the upper surface of the bottom plate, the arc surface is an arc-shaped structure to assist heat and temperature reflux, the top column supports an object and forms a certain space with the lower end to allow heat and temperature to flow, the control box controls the overall operation and movement, and the top column is a cylindrical structure and is provided with six.

[0015] As a further improvement of the present invention, the isolation door includes an arc groove and a thermal insulation board. The arc groove and the thermal insulation board are an integrated structure. The upper and lower ends of the arc groove are arc surface structures to assist the flow of heat and temperature. The thermal insulation board is composed of multiple layers of thermal insulation materials, so that the internal space of the tempering furnace can be isolated.

[0016] As a further improvement of the present invention, the tempering furnace feeding and transportation system and the tempering furnace control method are controlled as follows:

[0017] S1, place the material on the top column to form a certain space with the arc surface at the bottom, and transmit the moving signal through the background system, which is received by the control box and drives the placing rack as a whole to move along the vertical path to the inside of the tempering furnace, and control the isolation door to move down to the lowest point through the lifting frame, so that the inside and outside of the tempering furnace are separated;

[0018] S2, the size and time of the switch can be adjusted by the system settings at the flame spraying point inside the tempering furnace, the duration of the flame spraying or the regular start and stop can be set, and the arc surface structure of the arc surface and arc groove assists the circulation of the heat and temperature inside the tempering furnace;

[0019] S3, when the tempering furnace stops running, the time for automatically opening the isolation door after the tempering furnace is left to cool down can be set through the background system according to the needs. After the isolation door is opened, the gripping rack will move to the front of the placement rack, and the gripping head will be controlled by the rotation of the mounting rack to grip the material;

[0020] S4, after the clamping head clamps the material, it returns to the original position and moves forward along the horizontal path to transport the material to the next process, and then moves to the next tempering furnace to clamp the material in sequence.

[0021] The clamping head is made of high temperature resistant material as a whole and can clamp materials stably.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. When the clamping head clamps the material, its resilient body is in an extruded state, and the pressure frame drives the movable body to retract along the gap between the clamping teeth, so that the clamping teeth are exposed to clamp the material. After the material is unloaded, the resilient body will support the pressure frame and the movable body back to their original positions, and the movable body will remove the impurities and debris stuck between the clamping teeth along the gap between the clamping teeth during the movement process to prevent the impurities from agglomerating between the clamping teeth and affecting the fit and stability of the subsequent clamping.

[0024] 2. When the clamping head clamps the material, the drag rod swings to adjust the angle, and the swivel can rotate in all directions to adjust the clamping angle. The swing between the swing body and the swivel enables the clamping head to keep the clamping head and the material in a horizontal state and clamp them firmly through the swing of the swing body during the tilting of the drag rod. The drag rod at the rear end adjusts the overall balance effect through the control of the movable rod, so that the clamping head can clamp the material firmly.

[0025] 3. The tempering furnace is a box-type structure, and several can be installed side by side at the same time, and run at the same time to improve efficiency. When the clamping rack is running, it can be in a vertical state with the clamping rack, so that the clamping rack can clamp the materials in turn.

[0026] 4. While supporting and fixing the material, the top column allows the material to have a certain spatial distance from the arc surface, so that the bottom of the material can also be fully processed. The arc surface and the arc groove are both arc surface structures, which can guide the internal heat and temperature flow to make it reflux, preventing a large amount of heat and temperature from squeezing into the gap closed by the isolation door and affecting its sealing.

The swivel 52 is installed between the clamping head 51 and the drag rod 56. The support shaft 53 supports the drag rod 56 and is fixed to the inner side of the mounting frame 54. The upper end of the movable rod 55 is connected to the drag rod 56 and can swing. The lower end of the movable rod 55 is fixed to the outer surface of the fixed seat 58. The turntable 57 is installed between the mounting frame 54 and the fixed seat 58.

[0040] The clamping head 51 includes a movable plate 11, an adjustment slot 12, a pendulum body 13, and a main clamp body 14. The movable plate 11 is connected to the main clamp body 14. The main clamp body 14 is assembled in the adjustment slot 12 for movement and adjustment. The pendulum body 13 is fixed to the outer surface of the adjustment slot 12.

[0041] The movable plate 11 includes a fixed plate 21, a resilient body 22, a pressure frame 23, a groove pattern 24, a movable body 25, and clamping teeth 26. The resilient body 22 is installed between the pressure frame 23 and the fixed plate 21. The upper and lower ends of the movable body 25 are fixed to the pressure frame 23. The movable body 25 and the clamping teeth 26 are complementary to each other at intervals. The groove pattern 24 and the pressure frame 23 are an integrated structure. The support shaft 53 supports the axis point of the swing of the fixed drag rod 56. The swivel 52 can rotate in all directions, and its swing body 13 can swing in a fan shape, so that the clamping head 51 can be adjusted at multiple angles when clamping materials, which is more flexible and convenient.

[0042] Among them, the horizontal channel 6 and the vertical channel 7 are perpendicular to each other, the isolation door 3 moves to the lowest point to separate the tempering furnace 1 from the space outside, the placement rack 4 carries the material and moves back and forth along the vertical channel 7, the tempering furnace 1 is a box-type structure, and multiple tempering furnaces 1 can be installed side by side and operate simultaneously as needed. When multiple tempering furnaces 1 are assembled side by side, they can be vertical to the clamping rack 5, and can be increased or decreased according to the number of tempering furnaces 1, so that the clamping rack 5 rotates in sequence to take the material.

[0043] Among them, the turntable 57 can control the overall rotation of the mounting frame 54, the swivel 52 can control the rotation of the clamping head 51, the extension of the movable rod 55 controls the swing angle of the drag rod 56, the fixed seat 58 is divided into an upper and lower part, the upper part can rotate together with the turntable 57, the movable rod 55 is installed at a position near the tail of the drag rod 56 to assist in the balance of the overall clamping of objects, and the drag rod 56 is equipped with a power control group to control the overall power activity. The clamping head 51 moves to the left and right sides through power to adjust the clamping range of the material, and can be tightened and clamped according to the size of the material. The upper end of the movable rod 55 is hinged with the drag rod 56, and the swing direction and range of the drag rod 56 are adjusted according to the extension and contraction length of the movable rod 55 itself, so that it can better adjust the clamping of materials.

[0044] Among them, the two resilient bodies 22 form a symmetrical structure in a group and have a rebound support effect. The movable body 25 is provided with four and is gap-matched with the clamping teeth 26. The groove pattern 24 and the pressure frame 23 form a concave-convex surface to increase the contact friction. When the movable body 25 is in a stationary state, the outer side surface is more protruding than the clamping teeth 26. When the pressure frame 23 contacts the material, it will drive the movable body 25 to be squeezed in the direction of the fixed plate 21, thereby shrinking in the gap of the clamping teeth 26, so that the clamping teeth 26 can expose the body and contact and clamp the material. When the material is removed, the pressure frame 23 will use the rebound force of the resilient body 22 to push out the movable body 25 and the pressure frame 23 together, thereby pushing out the impurities in the gap of the clamping teeth 26 to prevent subsequent accumulation and agglomeration.

[0045] The specific usage and function of this embodiment are as follows:

[0046] In the present invention, the material to be processed is placed on the placing rack 4, and the vertical channel 7 is controlled by the background system to move the material into the tempering furnace 1. The isolation door 3 is controlled to descend by the lifting rack 2 to separate the space inside the tempering furnace 1. The open flame inside the tempering furnace 1 is started and opened to the required size and time by the background to temper the material inside. When the heating is finished and the set static cooling time has passed, the isolation door 3 will be opened, and the clamping rack 5 is moved along the horizontal channel 6 to a point perpendicular to the tempering furnace 1. The mounting rack 54 is driven to rotate as a whole by the turntable 57, and the movable rod 55 is telescopically adjusted to make the drag rod 56 swing along the support shaft 53 to a suitable position, and then the swivel 52 is rotated to make the opening of the clamping head 51 align with the material, and the swing body 13 is swung and adjusted along the swivel 52 so that the clamping head 51 can be flush with the material, which is convenient for clamping the material and adjusting. The groove 12 controls the main clamping body 14 to open to both sides, and moves the two parts of the main clamping body 14 to the upper and lower ends of the material surface respectively. The main clamping body 14 is clamped to the middle end by adjusting the groove 12, so that the pressure frame 23 first contacts the material to drive the movable body 25 to squeeze in the direction of the fixed plate 21, and the resilient body 22 is bent by force to maintain its own supporting force. After the pressure frame 23 is compressed, the movable body 25 will retreat to the rear side through the gap between the clamping teeth 26, allowing the clamping teeth 26 to clamp the material. After the material is clamped firmly, the movable rod 55 at the rear end of the drag rod 56 plays a certain balancing role, allowing the clamping frame 5 to transport the material to the next process. When the material leaves the clamping head 51, the resilient body 22 uses its own supporting force to support the pressure frame 23 and the movable body 25 back to their original positions, allowing the movable body 25 to move out again along the gap between the clamping teeth 26 to remove the remaining impurities.

[0047] Embodiment 2: As attached Figure 6 To Attachment Figure 8 As shown:

[0048] Among them, the placement rack 4 includes a top column 41, a curved surface 42, a bottom plate 43, and a control box 44. The curved surface 42 is fixed to the upper surface of the bottom plate 43, and the control box 44 is connected to the bottom plate 43. The top column 41 passes through the curved surface 42 and is fixed to the upper surface of the bottom plate 43. The curved surface 42 is an arc-shaped structure to assist heat and temperature reflux. The top column 41 supports the object and forms a certain space with the lower end to allow the heat and temperature to flow. The control box 44 controls the overall operation and movement. The top column 41 is a cylindrical structure and is provided with six. The bottom plate 43 is made of heat-insulating material.

[0049] Among them, the isolation door 3 includes an arc groove 31 and an insulation plate 32. The arc groove 31 and the insulation plate 32 are an integrated structure. The upper and lower ends of the arc groove 31 are arc surface structures to assist the flow of heat and temperature. The insulation plate 32 is composed of a combination of multiple layers of heat-insulating materials, so that the internal space of the tempering furnace 1 can be isolated. The arc surface structure of the arc groove 31 can guide the heat and temperature inside to have a certain activity trajectory through the arc when the only heat and temperature inside meets the body.

[0050] Among them, the tempering furnace feeding and transportation system and the tempering furnace control method are controlled as follows:

[0051] S1, place the material on the top column 41 to form a certain space with the arc surface 42 at the bottom, transmit the moving signal through the background system, and the control box 44 receives it to drive the placing rack 4 as a whole to move along the vertical path 7 to the inside of the tempering furnace 1, and control the isolation door 3 to move downward to the lowest point through the lifting frame 2, so that the inside and outside of the tempering furnace 1 are separated;

[0052] S2, the size and time of the switch can be adjusted by the system setting at the flame spraying point inside the tempering furnace 1, the duration of the flame spraying or the regular start and stop can be set, and the arc surface structure of the arc surface 42 and the arc groove 31 assists the circulation direction of the heat temperature inside the tempering furnace 1;

[0053] S3, when the tempering furnace 1 stops running, the time for automatically opening the isolation door 3 after the tempering furnace 1 is left to cool down can be set through the background system according to the needs. After the isolation door 3 is opened, the clamping rack 5 will move to the front of the placement rack 4, and the clamping head 51 will be controlled by the mounting rack 54 to clamp the material;

[0054] S4, after the material is clamped by the clamping head 51, it returns to the right position and moves forward along the transverse path 6 to transport the material to the next process, and then moves to the next tempering furnace 1 to clamp the material in sequence.

[0055] The clamping head 51 is made of high temperature resistant material as a whole and can stably clamp materials. The support shaft 53 is the axis point. When the clamping head 51 clamps materials, the rear end is connected and fixed by the movable rod 55 for balance.

[0056] The specific usage and function of this embodiment are as follows:

[0057] In the present invention, when the material is placed on the placing rack 4, it is supported by the top column 41, so that there is a certain space between the material and the arc surface 42, and the bottom of the material can be more fully processed. The arc surface structure of the arc surface 42 itself can assist the heat inside the tempering furnace 1 to guide the flow direction, so that it is in a reflux state, so that the material can be fully processed. While the isolation door 3 isolates the tempering furnace 1, the upper and lower ends of the arc groove 31 on its inner wall are also arc surface structures, which can guide the reflux effect of the heat and prevent the heat from being squeezed into the closed gap in large quantities, thereby affecting its sealing.
