The purpose of drawing is to improve the surface quality and dimensional accuracy of the metal, while also enhancing its mechanical properties, such as strength and hardness. Its working principle involves introducing the metal bar into a die; under tensile force, the metal is drawn through the die orifice to the desired size.

A transmission pipe is fixedly connected to the inner wall of the storage cavity. A connecting pipe is fixedly connected to the end of the transmission pipe away from the storage cavity. A drag frame is fixedly connected to the bottom of the connecting pipe. Delivery pipes are fixedly connected to both sides of the inner wall of the drag frame. A fixing component is provided at the bottom of the drag frame to absorb the coolant inside the storage cavity into the connecting pipe through the transmission pipe.

[0014] According to the above technical solution, the fixing component includes a covering ring, which is slidably connected to the top of the placement tube and fixedly connected to the bottom of the drag frame. A connecting ring is fixedly connected to the inner wall of the covering ring, and an adsorption block is fixedly connected to the inner wall of the connecting ring. A fixing arm is fixedly connected to one end of the covering ring, and a buffer pad is fixedly connected to the end of the fixing arm away from the covering ring.

[0015] According to the above technical solution, the bottom of the contact ring is provided with a contact groove, the buffer pad is made of a retractable and resetting material, the adsorption block is made of a magnetically adsorbable material, the transmission tube has a stretchable characteristic, the storage cavity is filled with coolant, and the connecting tube is provided with a connecting cavity. When the rod squeezes the buffer pad, the buffer pad will retract inward into the interior of the fixed arm.

[0016] According to the above technical solution, the installation mechanism includes an installation plate, which is fixedly connected to the inner wall of the installation platform. An adsorption plate is fixedly connected to the bottom of the inner wall of the installation plate. A connecting component is provided on the inner wall of the installation plate, which continues to extend and retract into the interior of the installation plate after passing through the inside of the clamping ring.

[0017] According to the above technical solution, the connecting assembly includes a sliding tube, which is fixedly connected to the inner wall of the mounting plate. A clamping membrane is slidably connected to the inner wall of the sliding tube, and a sliding rod is slidably connected to the inner wall of the sliding tube. A clamping ring is fixedly connected to one end of the sliding rod. A movable cavity is fixedly connected to the top of the mounting plate, and a telescopic rod is slidably connected to the inner wall of the movable cavity. An adsorption plate is fixedly connected to one end of the telescopic rod, and the adsorption plate is slidably connected to the inner wall of the movable cavity. The telescopic rod drives the adsorption plate to slide outward to a certain distance.

[0018] According to the above technical solution, the surface of the adsorption plate is provided with adsorption holes, and a magnetic block is installed inside the adsorption holes. One end of the sliding rod is fixedly connected to the inner wall of the clamping mold through the inner wall of the sliding tube. The surface of the clamping mold is provided with friction texture, so that the adsorption plate adsorbs and fixes one end of the rod.

[0019] A method for drawing bar stock includes the following steps:

[0020] S1: Place the rod inside the placement tube, and slide the other end of the rod into the inner wall of the mounting platform. The rod is magnetically attracted to one end by the adsorption plate inside the mounting plate. When the telescopic rod moves the adsorption plate outward to a certain distance, the adsorption plate will adsorb and fix one end of the rod. At the same time, the controller switch inside the mounting platform will drive the sliding rod to slide on the inner wall of the sliding tube, and multiple clamping films will squeeze and contact one end of the rod.

[0021] S2: By activating the internal absorber switch of the connecting pipe, the coolant inside the storage chamber is absorbed into the connecting pipe through the transmission pipe. When the bar extrudes against the buffer pad, the coolant is discharged to the outside through the contact groove at the bottom of the contact ring, thereby cooling the surface of the stretched bar.

[0022] S3: One end of the rod passes through the inside of the connecting ring, and the surface of the rod comes into contact with the inside of the connecting ring. By activating the controller switch inside the covering ring, the adsorption block is moved from the inside of the connecting ring to the outside. The magnetic adsorption block inside the adsorption block and the surface of the rod are magnetically adsorbed, thereby adsorbing the rod into the inside of the connecting ring.

[0023] S4: The stretched end of the rod is placed inside the sedimentation ring, and the other end of the rod is inserted into the insertion tube. By turning on the current switch inside the magnetic pad, the other end of the rod is attracted to the inside of the insertion tube. The connecting rod is extended and retracted outward by the controller inside the mounting platform. After the contact strip makes a tight contact with the surface of the rod, the other end of the rod is attracted and fixed by the adhesive suction cups at the bottom of multiple absorption films.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] 1. This invention, by setting up an installation mechanism, compresses the clamping membrane when the sliding rod slides, causing the clamping membrane to expand and contract outward on the inner wall of the sliding tube. Multiple clamping membranes create compression contact with one end of the rod. Simultaneously, the sliding rod pulls the clamping ring when it slides, causing the clamping ring to contract inward and contact the rod, thereby improving the support stability of the rod. Since different types of rods have different volumes, this mechanism can improve the stability of fixing rods of different volumes.

[0026] 2. This invention, by setting up a storage mechanism, causes the buffer pad to retract inward into the fixed arm when the rod is squeezed, thereby compressing the coolant inside the fixed arm. The coolant is then discharged to the outside through the contact groove at the bottom of the contact ring, cooling the surface of the stretched rod. By setting up this mechanism, since the local heating points generated during the drawing of rods of different sizes and volumes are located at different positions on the rod, the sliding position of the covering ring on the surface of the rod can be adjusted to precisely cool the local heating points of the rod, thereby improving the cooling efficiency of the rod.

[0027] 3. By setting up a contact mechanism, the contact strip makes a tight contact with the surface of the rod, and then the adhesive suction cups at the bottom of multiple absorption films adsorb and fix one end of the rod. At the same time, the absorption blocks inside the absorption films can absorb the noise generated when the rod is stretched by the connecting plate. By setting up this mechanism, the stability of the stretched end of the rod can be improved, and the noise generated when the rod is stretched can be reduced.

[0028] 4. This invention, by setting a fixing component, allows the rod to be placed inside the placement tube. One end of the rod passes through the inside of the connecting ring, and the surface of the rod contacts the inside of the connecting ring. By activating the controller switch inside the covering ring, the adsorption block extends and retracts from the inside of the connecting ring to the outside. The magnetic adsorption block inside the adsorption block magnetically attracts the surface of the rod, thereby adsorbing the rod inside the connecting ring. By setting this component, the reinforcement distance can be effectively adjusted according to different rod lengths to improve the safety of the rod during drawing. This solution can improve the technical problems in the manufacturing of high-quality aluminum alloy plates, high-quality magnesium materials, copper materials, and titanium materials.

[0038] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0039] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0040] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0041] Example 1: See Figures 1-4 The present invention provides a technical solution: a bar drawing device, including a base 1, a sliding table 3 fixedly connected to the top of the base 1, a stretching seat 5 slidably connected to the surface of the sliding table 3, and a contact mechanism 9 provided on the inner wall of the stretching seat 5.

[0042] The mounting mechanism 7 includes a mounting plate 701, which is fixedly connected to the inner wall of the mounting platform 2. An adsorption plate 702 is fixedly connected to the bottom of the inner wall of the mounting plate 701. A connecting component 703 is provided on the inner wall of the mounting plate 701. First, the rod is placed inside the placement tube 6. By pushing one end of the rod, the other end of the rod slides into the inner wall of the mounting platform 2. After passing through the inside of the clamping ring 7033, one end of the rod continues to extend and retract into the inside of the mounting plate 701. The adsorption plate 702 inside the mounting plate 701 and the rod end are magnetically attracted, thereby fixing one end of the rod inside the mounting plate 701.

[0043] The connecting assembly 703 includes a sliding tube 7031, which is fixedly connected to the inner wall of the mounting plate 701. A clamping membrane 7037 is slidably connected to the inner wall of the sliding tube 7031, and a sliding rod 7032 is slidably connected to the inner wall of the sliding tube 7031. A clamping ring 7033 is fixedly connected to one end of the sliding rod 7032. A movable cavity 7034 is fixedly connected to the top of the mounting plate 701. A telescopic rod 7035 is slidably connected to the inner wall of the movable cavity 7034, and an adsorption plate 7036 is fixedly connected to one end of the telescopic rod 7035. The adsorption plate 7036 is slidably connected to the inner wall of the movable cavity 7034. At this time, the internal control of the mounting platform 2 is activated. The switch is activated, which causes the internal telescopic rod 7035 of the movable cavity 7034 to slide and extend outward. When the telescopic rod 7035 drives the adsorption plate 7036 to slide outward to a certain distance, the current switch inside the mounting plate 701 is activated, which energizes the electromagnet inside the adsorption plate 7036 and generates magnetism, thereby causing the adsorption plate 7036 to adsorb and fix one end of the rod. At the same time, the internal controller switch of the mounting platform 2 drives the sliding rod 7032 to slide on the inner wall of the sliding tube 7031. When the sliding rod 7032 slides, it will squeeze the clamping membrane 7037, causing the clamping membrane 7037 to extend and extend outward on the inner wall of the sliding tube 7031.

[0044] During the drawing process, the rods need to be fixed. However, the length and volume of the rods need to be considered when drawing different types of rods, so the fixing angle and range of the rods need to be adjusted. Currently, the clamping method for fixing rods of different volumes is quite cumbersome, so a connecting component 703 needs to be set up.

[0045] The surface of the adsorption plate 7036 is provided with adsorption holes, and magnetic blocks are installed inside the adsorption holes. One end of the sliding rod 7032 is fixedly connected to the inner wall of the clamping mold through the inner wall of the sliding tube 7031. The surface of the clamping membrane 7037 is provided with friction texture. Multiple clamping membranes 7037 generate extrusion contact with one end of the rod. At the same time, when the sliding rod 7032 slides, it pulls the clamping ring 7033, causing the clamping ring 7033 to contract inward and contact the rod, thereby improving the support stability of the rod. Since different types of rods have volume differences, it can improve the stability of rods of different volumes during fixed drawing.

[0046] Example 2: Based on Example 1, please refer to the following... Figures 5-6 The present invention provides a technical solution: the storage mechanism 8 includes a storage cavity 801, the storage cavity 801 is fixedly connected to the surface of the mounting platform 2, a transmission pipe 802 is fixedly connected to the inner wall of the storage cavity 801, a connecting pipe 803 is fixedly connected to the end of the transmission pipe 802 away from the storage cavity 801, a drag frame 805 is fixedly connected to the bottom of the connecting pipe 803, a conveying pipe 804 is fixedly connected to both sides of the inner wall of the drag frame 805, and a fixing component 806 is provided at the bottom of the drag frame 805. By activating the absorber switch inside the connecting pipe 803, the coolant inside the storage cavity 801 is absorbed into the connecting pipe 803 through the transmission pipe 802, and the coolant is discharged into the internal cavity of the drag frame 805 through the conveying pipe 804.

[0047] The fixing component 806 includes a covering ring 8061, which is slidably connected to the top of the placement tube 6 and fixedly connected to the bottom of the drag frame 805. A connecting ring 8062 is fixedly connected to the inner wall of the covering ring 8061. The drag frame 805 discharges coolant into the fixing arm 8064. When the covering ring 8061 slides on the top of the placement tube 6, it will stretch the transmission tube 802. At the same time, it will cause the contact ring 8066 to contact the rod inside the placement tube 6. When the rod squeezes the buffer pad 8065, it will cause the buffer pad 8065 to retract inward into the interior of the fixing arm 8064, thereby compressing the coolant inside the fixing arm 8064.

[0048] An adsorption block 8063 is fixedly connected to the inner wall of the connecting ring 8062. A fixing arm 8064 is fixedly connected to one end of the covering ring 8061. A buffer pad 8065 is fixedly connected to the end of the fixing arm 8064 away from the covering ring 8061. A contact ring 8066 is fixedly connected to the bottom of the buffer pad 8065, so that the coolant is discharged to the outside through the contact groove at the bottom of the contact ring 8066. The surface of the stretched bar is cooled by the coolant to control the drawing temperature, avoid overheating due to heat generated by plastic deformation, and prevent oxidation of the bar surface, which would reduce toughness. Since the local heating points generated during the drawing of bars of different sizes and volumes are located at different positions on the bar, the sliding position of the covering ring 8061 on the surface of the bar can be adjusted to precisely cool the local heating points of the bar, thereby improving the cooling efficiency of the bar.

[0049] When bars are drawn, the surface of the material will be locally heated, which requires cooling. The range of the local heating area on the surface of the bar will vary when bars of different lengths and volumes are drawn, so a fixing component 806 is required.

[0050] The bottom of the contact ring 8066 has a contact groove, the buffer pad 8065 is made of a retractable and repositionable material, the adsorption block 8063 is made of a magnetically adsorbable material, the transmission tube 802 has a stretchable characteristic, the storage cavity 801 is filled with coolant, and the connecting tube 803 has a connecting cavity. When the rod is placed inside the placement tube 6, one end of the rod passes through the inside of the connecting ring 8062, and the surface of the rod comes into contact with the inside of the connecting ring 8062. By activating the controller switch inside the covering ring 8061, the adsorption block 8063 is moved to extend and retract from the inside of the connecting ring 8062. The magnetic adsorption block inside the adsorption block 8063 magnetically adsorbs the surface of the rod, thereby adsorbing the rod inside the connecting ring 8062. The reinforcement distance can be effectively adjusted according to the length of the rod to improve the safety of the rod during drawing.

[0051] Example 3: Based on Example 2, please refer to the following... Figures 7-8 The present invention provides a technical solution: the contact mechanism 9 includes a sedimentation ring 901, which is fixedly connected to the inner wall of the stretching seat 5. A fixing ring 903 is fixedly connected to the inner wall of the sedimentation ring 901. A connecting rod 904 is slidably connected to one end of the sedimentation ring 901. A snap ring 902 is fixedly connected to the end of the sedimentation ring 901 away from the connecting rod 904. A shrinkage component 905 is provided at the end of the connecting rod 904 away from the sedimentation ring 901. After one end of the rod is placed inside the placement tube 6, the stretched end of the rod is placed inside the sedimentation ring 901 and comes into contact with the fixing ring 903.

[0052] The shrinking assembly 905 includes a connecting plate 9051, which is fixedly connected to one end of the connecting rod 904. The inner wall of the connecting plate 9051 is fixedly connected to the insertion tube 9052. At the same time, one end of the rod is inserted into the insertion tube 9052. By turning on the current switch inside the magnetic pad 9053, the coil inside the magnetic pad 9053 is energized and the magnetic block is magnetized, and one end of the rod is attracted to the inside of the insertion tube 9052.

[0053] The shrink assembly 905 also includes a magnetic suction pad 9053, which is fixedly connected to the inner wall of the insertion tube 9052. A contact strip 9054 is fixedly connected to the end of the insertion tube 9052 away from the connecting plate 9051. An absorbent membrane 9056 is fixedly connected to the bottom of the contact strip 9054. An absorbent block 9055 is fixedly connected to the inner wall of the absorbent membrane 9056. The end of the contact strip 9054 away from the insertion tube 9052 is fixedly connected to the surface of the snap ring 902. A mounting platform 2 is fixedly connected to the top of the base 1. A placement tube 6 is fixedly connected to the inner wall of the mounting platform 2. The end of the placement tube 6 away from the mounting platform 2 is fixedly connected to the surface of the tension seat 5. A tension rod 4 is fixedly connected to one end of the mounting platform 2. The tension seat 5... The surface of the mounting platform 2 is provided with a storage mechanism 8 and the connecting rod 904 is slidably connected to the surface of the tension rod 4. The extension and retraction distance of the connecting rod 904 on the inner wall of the sedimentation ring 901 is adjusted by rods of different lengths. The connecting rod 904 is driven to extend and retract outward by the internal controller of the mounting platform 2, thereby causing the connecting plate 9051 to slide inward and outward by a distance that matches the pulling position of the rod. When the connecting plate 9051 slides outward, it will cause the contact strip 9054 to extend and retract outward. This will cause one end of the contact strip 9054 on the surface of the snap ring 902 to be stressed and tightened. After the contact strip 9054 makes tight contact with the surface of the rod, the sticky suction cups at the bottom of the multiple absorption films 9056 will adsorb and fix one end of the rod.

[0054] When one end of bars of different sizes and volumes is being drawn, the force coefficient of the drawn end needs to be intelligently adjusted to prevent the bar from being pulled out of the clamping device due to excessive force. Therefore, a shrinkage component 905 is required.

[0055] The top of the placement tube 6 has a sliding groove, the surface of the magnetic pad 9053 has magnetic holes, and a magnetic block is installed inside the magnetic pad 9053. The bottom of the absorption membrane 9056 has an absorption groove. Simultaneously, the absorption block 9055 inside the absorption membrane 9056 can absorb the noise generated when the rod is stretched by the connecting disc 9051, thus improving the stability of the stretched end of the rod and reducing noise generated during stretching. The precise cooling of localized heating points during rod drawing and the intelligent adjustment of the fixed angle for drawing different types of rods proposed in this solution can solve technical problems in the manufacturing of high-quality aluminum alloy sheets, high-quality magnesium materials, copper materials, and titanium materials.

[0056] A method for drawing bar stock includes the following steps:

[0057] S1: Place the rod inside the placement tube 6, and slide the other end of the rod into the inner wall of the mounting platform 2. The rod is magnetically attracted to one end by the adsorption plate 702 inside the mounting plate 701. When the telescopic rod 7035 drives the adsorption plate 7036 to slide outward to a certain distance, the adsorption plate 7036 adsorbs and fixes one end of the rod. At the same time, the controller switch inside the mounting platform 2 drives the sliding rod 7032 to slide on the inner wall of the sliding tube 7031, and the rod end is squeezed and contacted by multiple clamping films 7037.

[0058] S2: By activating the internal absorber switch of the connecting pipe 803, the coolant inside the storage chamber 801 is absorbed into the connecting pipe 803 through the transmission pipe 802. When the bar extrudes the buffer pad 8065, the coolant is discharged to the outside through the contact groove at the bottom of the contact ring 8066, and the surface of the stretched bar is cooled by the coolant.

[0059] S3: One end of the rod passes through the inside of the connecting ring 8062, and the surface of the rod comes into contact with the inside of the connecting ring 8062. By activating the controller switch inside the covering ring 8061, the adsorption block 8063 is driven to extend and retract from the inside of the connecting ring 8062 to the outside. The magnetic adsorption block inside the adsorption block 8063 and the surface of the rod are magnetically adsorbed, thereby adsorbing the rod into the inside of the connecting ring 8062.

[0060] S4: The stretched end of the rod is placed inside the sedimentation ring 901, and the other end of the rod is inserted into the insertion tube 9052. By turning on the current switch inside the magnetic pad 9053, the other end of the rod is attracted to the inside of the insertion tube 9052. The connecting rod 904 is extended and retracted outward by the internal controller of the mounting platform 2. After the contact strip 9054 makes a tight contact with the surface of the rod, the other end of the rod is attracted and fixed by the adhesive suction cups at the bottom of the multiple absorption films 9056.
