[0002] Most existing seamless door frames are made by extruding steel pipes. When extruding steel pipes, people need to manually bend the steel pipes, and then use a forming machine to extrude the bent steel pipes.

[0003] Patent application CN111014500A discloses a forming device for seamless door frame processing, including a forming worktable and a receiving table. A vertical plate is provided on the upper surface of the forming worktable, and an upper forming roller is slidably installed inside the vertical plate. A lower forming roller is rotatably installed inside the forming worktable, directly below the upper forming roller. An adjustment assembly is provided above the upper forming roller, including a motor. Two sets of first pulleys are fixedly installed on the output shaft end of the motor. A support plate is fixedly installed at one end of the upper forming roller, and the support plate is slidably connected to the vertical plate. In use, the lifting motor is started, and the distance between the upper and lower forming rollers is adjusted simultaneously, allowing for the extrusion forming of the door frame. After forming, drilling is required to drill holes in the door frame, making this device inconvenient for drilling the door frame.

[0004] Therefore, an extrusion molding device for seamless door frame processing is being developed to facilitate drilling of door frames. Summary of the Invention

[0005] In order to overcome the disadvantage of the above-mentioned patents that make it inconvenient for people to drill holes in the door frame, the technical problem to be solved is: to provide a seamless door frame processing extrusion molding device that facilitates drilling holes in the door frame.

[0006] The technical solution is as follows: A seamless door frame extrusion molding device includes a worktable, support legs, mounting brackets, a first hydraulic cylinder, a first pressure plate, a first spring, an extrusion frame, a limiting frame, a pushing mechanism, and a drilling mechanism. Support legs are connected to the lower front side of the worktable. A mounting bracket is bolted to the upper side of the worktable. First hydraulic cylinders are connected to both the front and rear sides of the mounting bracket. First pressure plates are connected to the telescopic rods of the first hydraulic cylinders. An extrusion frame is slidably connected between the two first pressure plates. First springs are symmetrically connected to the upper side of the first pressure plates on both the front and rear sides of the top of the extrusion frame. The first springs are all wound around the extrusion frame. A limiting frame is connected to the upper side of the worktable and is located between the mounting brackets. A pushing mechanism for extruding steel pipes and a drilling mechanism for drilling holes in the door frame are provided on the worktable. The steel pipe is placed on the upper front side of the worktable. The pushing mechanism limits the steel material, and then the middle of the steel pipe is pushed backward for extrusion molding. Finally, the drilling mechanism is used to drill holes in the molded door frame.

[0007] As a further preferred embodiment, the pushing mechanism includes a second hydraulic cylinder, a pushing frame, baffles, and rotating wheels. The second hydraulic cylinders are connected to both sides of the upper inner wall of the worktable, and the pushing frame is connected between the telescopic rods of the two second hydraulic cylinders. Baffles are connected to both sides of the front part of the top wall of the worktable. Rotating wheels are rotatably connected between the side of the baffles that are close to each other and the left and right sides of the front wall of the limiting frame. The steel pipe is placed in front of the baffle, and then the pushing frame is moved backward by the second hydraulic cylinder to squeeze the steel pipe, so that the door frame is formed.

[0008] As a further preferred embodiment, the drilling mechanism includes a guide frame, a motor, a pusher, a drill bit, and a second spring. Guide frames are symmetrically connected to the left and right sides of the upper part of the worktable. A pusher is slidably connected between the two guide frames on the left side, and also between the two guide frames on the right side. Motors are connected to the front and rear sides of the pusher, and drill bits are connected to the output shafts of the motors. Two second springs are connected between the left side of the pusher and the left side of the guide frame, and two second springs are also connected between the right side of the pusher and the right side of the guide frame. The second springs are all wound around the guide frames. The door frame that has been extruded and formed is located inside the limiting frame. Then, the drill bit is rotated by the motor. Next, the first pressure plate moves downward and pushes the drill bits on the left and right sides to move towards each other through the pusher, thus drilling holes in the formed door frame.

[0009] As a further preferred embodiment, a heating mechanism for heating the bent section of the steel pipe is also included. The heating mechanism includes a first material tank, a second material tank, a connecting double air pipe, and a heating gun. The first material tank is connected to both the left and right sides of the worktable, and the second material tank is connected to both the left and right sides of the worktable. The second material tank is located behind the first material tank. The heating gun is connected to both the left and right sides of the upper front part of the worktable. The heating gun on the left side is connected to the connecting double air pipe, and the left part of the connecting double air pipe on the left side is connected to the upper side of the first and second material tanks on the left side. The heating gun on the right side is also connected to the connecting double air pipe, and the right part of the connecting double air pipe on the right side is connected to the upper side of the first and second material tanks on the right side. The gases in the first and second material tanks are mixed by the heating gun, and then the mixture sprayed by the heating gun is ignited to heat the bent section of the steel pipe, thereby softening the bent section of the steel pipe.

[0010] As a further preferred embodiment, a cooling mechanism for cooling the drill bit is also included. The cooling mechanism includes a pusher frame, a liquid storage tank, a connecting pipe, and a pressure-opening valve. The pusher frame is connected to the middle of the upper side of the pusher frame, and the liquid storage tank is connected to both sides of the mounting frame. The connecting pipe is connected to the lower side of the liquid storage tank, and the opening of the connecting pipe is located above the drill bit. The pressure-opening valve is slidably connected to the upper part of the connecting pipe. When the pusher frames on the left and right sides move closer to each other, the pusher frame will push the pressure-opening valve to open, and then the coolant in the liquid storage tank will flow out through the connecting pipe to cool the drill bit.

[0011] As a further preferred embodiment, it also includes an ignition mechanism for igniting the gas ejected from the heating gun. The ignition mechanism includes an igniter, a button, a connecting plate, a second pressure plate, and a third spring. Igniters are connected to the left and right sides of the upper front of the worktable. The igniters are located below the heating gun. A button is slidably connected to the front of each igniter. A connecting plate is connected between the front parts of the igniters. A second pressure plate is slidably connected to the connecting plate. Two third springs are connected between the rear side of the second pressure plate and the front side of the connecting plate. The third springs are wound around the connecting plate and are arranged symmetrically on the left and right. Moving the second pressure plate backward will squeeze the button to open, so that the igniter ignites the mixture ejected from the heating gun.

[0012] As a further preferred embodiment, a positioning mechanism for positioning the steel pipe is also included. The positioning mechanism includes a mounting component, a stop block, and a fourth spring. The mounting component is connected to the front right side of the worktable, and the stop block is slidably connected to the right side of the mounting component. Two fourth springs are connected between the stop block and the upper left side of the mounting component. The two fourth springs are symmetrically arranged front and back, and both fourth springs are wound around the stop block. The steel pipe is positioned by contacting the stop block with the right side of the steel pipe.

[0013] As a further preferred option, the front side of the baffle is arc-shaped and fits against the outer wall of the steel pipe.

[0014] The beneficial effects are: 1. The present invention facilitates the production of seamless door frames by combining the extrusion frame and the limiting frame, and also facilitates the drilling of the door frame for later installation. Furthermore, it eliminates the need for bending the steel pipe with tools, thereby reducing labor and improving the efficiency of door frame production.

[0015] 2. This invention uses a heating gun to heat the steel pipes used to make the door frame, causing them to soften and making it easier for people to manufacture the door frame later.

[0016] 3. The present invention sprays coolant through a connecting pipe, which can cool the drill bit and prevent it from being damaged due to excessive temperature. Attached Figure Description

Detailed Implementation

[0030] The present invention will be further described below with reference to specific embodiments. The illustrative embodiments and descriptions herein are used to explain the present invention, but are not intended to limit the present invention.

[0031] Example 1

[0032] An extrusion molding apparatus for seamless door frame processing, such as Figures 1-2 As shown, the device includes a worktable 1, support legs 2, mounting bracket 3, first hydraulic cylinder 4, first pressure plate 5, first spring 6, extrusion frame 7, limiting frame 8, pushing mechanism 9, and drilling mechanism 10. Support legs 2 are welded to the lower front side of the worktable 1, providing support. The mounting bracket 3 is bolted to the upper side of the worktable 1. First hydraulic cylinders 4 are connected to both the front and rear sides of the mounting bracket 3. First pressure plates 5 are connected to the telescopic rods of the first hydraulic cylinders 4. The telescopic rods of the first hydraulic cylinders 4 extend and retract, causing the first pressure plates 5 to move. The lifting mechanism has a sliding connection between the two first pressure plates 5 and an extrusion frame 7. The top front and rear sides of the extrusion frame 7 are symmetrically connected to the upper side of the first pressure plate 5 and a first spring 6 is connected to each other. The first spring 6 is wound around the extrusion frame 7. A limiting frame 8 is welded to the upper side of the worktable 1. The limiting frame 8 is located between the mounting brackets 3. The limiting frame 8 can limit and shape the steel pipe for making the door frame. The worktable 1 is equipped with a pushing mechanism 9 that can extrude and shape the steel pipe. The worktable 1 is also equipped with a drilling mechanism 10 that can drill holes in the door frame.

[0033] like Figure 1 and Figure 3As shown, the pushing mechanism 9 includes a second hydraulic cylinder 91, a pushing frame 92, a baffle 93, and a rotating wheel 94. The upper inner wall of the worktable 1 is bolted to both sides of the second hydraulic cylinder 91. The pushing frame 92 is welded between the telescopic rods of the two second hydraulic cylinders 91. The pushing frame 92 can push and shape the steel pipe. The upper inner wall of the worktable 1 is connected to both sides of the front part of the top wall of the worktable 1. The side of the baffle 93 that is close to each other is rotatably connected to the left and right sides of the front wall of the limiting frame 8. The rotating wheel 94 can facilitate the bending of the steel pipe.

[0034] like Figure 1 , Figure 4 and Figure 5 As shown, the drilling mechanism 10 includes a guide frame 101, a motor 102, a push frame 103, a drill bit 104, and a second spring 105. The guide frames 101 are symmetrically connected to the upper left and right sides of the worktable 1. The two guide frames 101 on the left side are slidably connected to the push frame 103, and the two guide frames 101 on the right side are also slidably connected to the push frame 103. When the first pressure plate 5 moves downward, it will squeeze the push frame 103 to move closer to each other. The motor 102 is connected to the front and rear sides of the push frame 103. The output shaft of the motor 102 is connected to the drill bit 104 that can drill holes in the door frame through a coupling. The left side of the push frame 103 is connected to the left guide frame 101, and the right side of the push frame 103 is connected to the right guide frame 101. The second springs 105 are all wound around the guide frame 101.

[0035] This device can be used to extrude and form steel pipes for door frames. First, the steel pipe is placed in front of the workbench 1, where the baffle 93 blocks it. Because the front of the baffle 93 is arc-shaped, it fits the steel pipe better. Then, when the middle of the steel pipe moves to the position directly behind the pusher frame 92, the bent portion of the steel pipe is heated and softened using a tool. Next, the second hydraulic cylinder 91 is activated, causing its telescopic rod to shorten rearward, moving the pusher frame 92 rearward. This rearward movement of the pusher frame 92 compresses and bends the steel pipe, while the limiting frame 8... The shape of the steel pipe can be defined. After the steel pipe is bent, the second hydraulic cylinder 91 is controlled to extend forward and return to its original position. Then, the second hydraulic cylinder 91 is closed, and the first hydraulic cylinder 4 and motor 102 are activated. The extension rod of the first hydraulic cylinder 4 extends downward, pushing the first pressure plate 5 and the extrusion frame 7 downward. When the extrusion frame 7 moves downward and contacts the steel pipe, the extrusion frame 7 stops moving. The first pressure plate 5 continues to move downward, which stretches the first spring 6. The extrusion frame 7 can extrude and shape the steel pipe. At the same time, the output shaft of motor 102 rotates, driving the drill bit 104 to rotate. When the first pressure plate 5... When the pusher 103 comes into contact with the pusher 103, the first pressure plate 5 pushes the pusher 103 to move closer together. At this time, the second spring 105 is stretched. The movement of the pusher 103 to move closer together drives the motor 102 and the drill bit 104 to move closer together. The drill bit 104 can drill holes in the steel pipe to facilitate the later installation of the door frame. After the steel pipe is extruded and drilled, the motor 102 is turned off and the extension rod of the first hydraulic cylinder 4 is controlled to shorten upward, causing the first pressure plate 5 to move upward. When the first spring 6 returns to its initial state, the first pressure plate 5 continues to move upward, which will drive the extrusion... When frame 7 moves upward, and the first pressure plate 5 separates from the pusher 103, the pusher 103 moves to the side away from each other under the action of the second spring 105, driving the motor 102 and the drill bit 104 to move to the side away from each other. Then, after the frame 7 is reset, the first hydraulic cylinder 4 is closed, and the door frame can be removed. Repeating the above operation makes it easier to make seamless door frames and drill holes in the door frame for later installation. It also eliminates the need to bend the steel pipe with tools, thus reducing labor and improving the efficiency of door frame production.

[0036] Example 2

[0037] Based on Example 1, such as Figure 1 and Figure 6As shown, it also includes a heating mechanism 11 capable of heating the bent part of the steel pipe. The heating mechanism 11 includes a first material tank 111, a second material tank 112, a connecting double air pipe 113, and a heating gun 114. The first material tank 111 is bolted to both the left and right sides of the worktable 1, and the second material tank 112 is bolted to both the left and right sides of the worktable 1. The second material tank 112 is located behind the first material tank 111. The heating gun 114 is connected to both the left and right sides of the upper front part of the worktable 1. The heating gun 114 can heat the bent part of the steel pipe to soften it. The front of the heating gun 114 on the left side is connected to the connecting double air pipe 113. The left part of the connecting double air pipe 113 on the left side is connected to the upper side of the first material tank 111 and the second material tank 112 on the left side. The front of the heating gun 114 on the right side is also connected to the connecting double air pipe 113. The right part of the connecting double air pipe 113 on the right side is connected to the upper side of the first material tank 111 and the second material tank 112 on the right side.

[0038] When making a door frame, the bent parts of the steel pipe need to be heated to soften them. First, a flame retardant is stored in the first material tank 111, and a combustible agent is stored in the second material tank 112. The heating gun 114 is turned on, which allows the flame retardant in the first material tank 111 and the combustible agent in the second material tank 112 to flow into the heating gun 114 through the connecting double gas pipe 113. Then, the heating gun 114 sprays out the mixture. The gas sprayed out by the heating gun 114 is then ignited with a tool. This process heats and softens the bent parts of the steel pipe, making it easier to make the door frame later. Once the steel pipe has softened and been heated, the heating gun 114 is turned off. Repeating the above operation can heat and soften the steel pipe used to make the door frame, making it easier to make the door frame later.

[0039] like Figure 1 , Figure 7 and Figure 8 As shown, it also includes a cooling mechanism 12 for cooling the drill bit 104. The cooling mechanism 12 includes a pusher 121, a liquid storage tank 122, a connecting pipe 123, and a pressure-opening valve 124. The pusher 121 is welded to the middle of the upper side of the pusher 103. The left and right sides of the mounting frame 3 are connected to liquid storage tanks 122 for storing coolant. The lower side of the liquid storage tank 122 is connected to a connecting pipe 123. The opening of the connecting pipe 123 is located above the drill bit 104. The upper part of the connecting pipe 123 is slidably connected to the pressure-opening valve 124. The pressure-opening valve 124 can control the flow of the connecting pipe 123. When the pusher 121 moves to one side closer to the other, it will push the pressure-opening valve 124 to open.

[0040] Because the drill bit 104 generates high temperatures when drilling into the door frame, it needs to be cooled. First, when the pusher 103 moves to the side closer to each other, it drives the pusher 121 to move to the side closer to each other. When the pusher 121 contacts the pressure-opening valve 124, the pusher 121 pushes the pressure-opening valve 124 to open. Then, the coolant in the reservoir 122 flows out to the drill bit 104 through the connecting pipe 123. This cools the drill bit 104 and prevents it from being damaged due to overheating. Then, when the pusher 103 moves to the side further away from each other to reset, it drives the pusher 121 to move to the side further away from each other to reset. When the pusher 121 separates from the pressure-opening valve 124, the pressure-opening valve 124 resets and closes under its own action. At this time, the coolant stops flowing out. Repeating the above operation can cool the drill bit 104 and prevent it from being damaged due to overheating.

[0041] like Figure 1 , Figure 9 and Figure 10 As shown, it also includes an ignition mechanism 13 capable of igniting the gas ejected from the heating gun 114. The ignition mechanism 13 includes an igniter 131, a button 132, a connecting plate 133, a second pressure plate 134, and a third spring 135. Igniters 131 are connected to the left and right sides of the upper front part of the worktable 1. The igniters 131 are located below the heating gun 114. The igniters 131 can ignite the gas ejected from the heating gun 114. A button 132 is slidably connected to the front side of each igniter 131. The button 132 can control the opening and closing of the igniter 131. A connecting plate 133 is connected between the front parts of the igniters 131. A second pressure plate 134 is slidably connected to the connecting plate 133. Two third springs 135 are connected between the rear side of the second pressure plate 134 and the front side of the connecting plate 133. The third springs 135 are both wound around the connecting plate 133 and are arranged symmetrically on the left and right.

[0042] When it is necessary to ignite the mixture sprayed from the heating gun 114, the person first pushes the second pressure plate 134 backward. At this time, the third spring 135 is compressed. The second pressure plate 134 moves backward and presses the button 132, which opens the igniter 131. This allows the mixture sprayed from the heating gun 114 to be ignited. After ignition, the person releases the second pressure plate 134. Under the action of the third spring 135, the second pressure plate 134 moves forward to reset. The movement of the second pressure plate 134 forward releases the button 132. Then, the button 132 resets under its own action, which closes the igniter 131. Repeating the above operation allows the mixture sprayed from the heating gun 114 to be ignited, thus eliminating the need for manual ignition with tools, reducing the risk factor and improving safety during ignition.

[0043] like Figure 1 , Figure 11 and Figure 12 As shown, it also includes a positioning mechanism 14 capable of positioning the steel pipe. The positioning mechanism 14 includes a mounting component 141, a stop block 142, and a fourth spring 143. The mounting component 141 is welded to the front right side of the workbench 1. The stop block 142 is slidably connected to the right side of the mounting component 141. The stop block 142 can position the steel pipe. Two fourth springs 143 are connected between the stop block 142 and the upper left side of the mounting component 141. The two fourth springs 143 are arranged symmetrically front and back, and both fourth springs 143 are wound around the stop block 142.

[0044] When positioning the steel pipe, the pipe is first placed on the workbench 1 from left to right. Then, when the right side of the pipe contacts the stop block 142, the pipe is stopped. The stop block 142 positions the pipe. If the pipe continues to move to the right, the stop block 142 will move to the right, at which point the fourth spring 143 is compressed. The fourth spring 143 cushions the pipe and prevents damage. Then, when the pipe separates from the stop block 142, the stop block 142 moves to the left and resets under the action of the fourth spring 143. Repeating the above operation positions the pipe, preventing the pipe from shifting when bent, and also cushioning the pipe and reducing the damage rate.

[0045] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
