Description

Technical Field

[0001] The utility model relates to the technical field of aluminum tube processing equipment, in particular to an extruder for aluminum tube production. Background Technique

[0002] The metal extruder is the most important equipment for realizing metal extrusion processing. Metal extrusion processing is an important method using metal plastic pressure forming. Its important feature is that the metal ingot blank can be processed into tubes, rods, and profiles in an instant, and hardly any other method can match it. Therefore, metal extruders are often used in aluminum tube processing.

[0003] For example, a thin-walled aluminum tube extruder with the authorization announcement number of "CN211331264U". Since the piston does not directly contact the liquefied aluminum, it will not drive aluminum chips to contact the inner wall. And due to the influence of the extruded air, there is generally no residual liquid aluminum on the inner wall of the extrusion box. And because it is liquefied aluminum, the length of the aluminum tube will not be limited by the length of the aluminum block. In this way, the aluminum tube can reach the required length without splicing, which avoids material waste, reduces its cost, and improves work efficiency. However, for this thin-walled aluminum tube extruder, the blocking block and the extrusion box form a mold, and the aluminum tube is formed through the mold. Since the size of the blocking block is fixed and cannot be replaced, only one kind of aluminum tube can be processed, which increases the work limitation. At the same time, for this thin-walled aluminum tube extruder, the aluminum tube is cooled by a fan. Since the position of the fan is fixed and cannot make the aluminum tube be cooled evenly, it is easy to cause the processed aluminum tube to be unqualified, thus reducing the work quality. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that the blocking block and the extrusion box form a mold, and the aluminum tube is formed through the mold. Since the size of the blocking block is fixed and cannot be replaced, only one kind of aluminum tube can be processed, which increases the work limitation. At the same time, for this thin-walled aluminum tube extruder, the aluminum tube is cooled by a fan. Since the position of the fan is fixed and cannot make the aluminum tube be cooled evenly, it is easy to cause the processed aluminum tube to be unqualified, thus reducing the work quality, and to propose an extruder for aluminum tube production.

[0005] To achieve the above purpose, the utility model provides the following technical solutions:

[0006] Design an extruder for aluminum tube production, including a bottom plate, a bent plate and a support plate. The upper end of the bottom plate is fixedly connected with the bent plate. Auxiliary cooling mechanisms are symmetrically arranged on the inner wall of the bent plate. Above the inner wall of the bent plate is fixedly connected with a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected with a piston. The outer wall of the hydraulic cylinder is slidably connected with the box body. There is a feed inlet on the left side of the box body. Cross plates are fixedly connected to both sides of the box body, and the outer walls of the cross plates are fixedly connected with the bent plate. Auxiliary fixing mechanisms are symmetrically arranged inside the support plate.

[0007] Preferably, both ends of the support plate are fixedly connected with the box body. The inner wall of the support plate is slidably connected with a blocking block. The outer wall of the piston is slidably connected with the box body.

[0008] Preferably, the auxiliary cooling mechanism includes a first outer shell. The outer walls of the first outer shell are fixedly connected with the bent plate. A first motor is fixedly connected to the inner wall of the first outer shell. There are two toothed pulleys inside the first outer shell. The rear end of the transmission shaft of the upper toothed pulley is fixedly connected with the output shaft of the first motor. The outer walls of the transmission shafts of the lower toothed pulleys are rotatably connected with the first outer shell through bearings. The outer walls of the toothed pulleys are meshed with a toothed belt. The right side of the toothed belt is fixedly connected with a slider. Convex blocks are fixedly connected to both sides of the slider. The outer walls of the convex blocks are slidably connected with a frame body. Both ends of the frame body are fixedly connected with the inner wall of the first outer shell. The outer wall of the slider is slidably connected with the first outer shell.

[0009] Preferably, the right end of the slider is fixedly connected with a motor box. A second motor is fixedly connected to the inner wall of the motor box. The output shaft of the second motor is fixedly connected with a fan.

[0010] Preferably, the auxiliary fixing mechanism includes a second outer shell. The lower ends of the second outer shell are fixedly connected with the support plate. The inner wall of the second outer shell is slidably connected with a handle. The right end of the handle is fixedly connected with a sliding rod. The outer wall of the sliding rod is slidably connected with a fixing block. Two clamping strips are fixedly connected to the outer wall of the sliding rod. A spring is sleeved on the outer wall of the sliding rod. The two ends of the spring are respectively fixedly connected with the fixing block and the clamping strip.

[0011] Preferably, the ends of the sliding rod and the clamping strip are both abutted against the blocking block. A box door is hinged on the outer wall of the box body. The outer wall of the handle is slidably connected with the support plate and the box body respectively.

[0012] For the extruder for aluminum tube production proposed by the present utility model, the beneficial effects are as follows: Through the cooperation of the support plate and the auxiliary fixing mechanism, when the handle moves, it drives the sliding rod to move, and at the same time compresses the spring. The movement of the sliding rod drives the clamping strip to move, so as to realize the replacement of the blocking block, and thus aluminum tubes of different models can be processed, thereby reducing the working limitations.

[0013] Through the cooperation of the bent plate and the auxiliary cooling mechanism, the rotation of the output shaft of the first motor drives the upper toothed pulley to rotate, thereby driving the toothed belt and the lower toothed pulley to rotate. The rotation of the toothed belt drives the slider to move, thereby driving the convex block to slide along the inner wall of the frame, so as to realize the reciprocating movement of the fan, uniformly cool the aluminum tube, reduce the probability of the processed aluminum tube being unqualified, and thus improve the working quality.

[0029] Working principle:

[0030] When using an extruder to produce aluminum tubes:

[0031] Preparation process:

[0032] The operator first selects a suitable blocking block 5 according to the radius of the aluminum tube to be produced, opens the box door 13. The operator first pulls the left handle 902 to the left. The movement of the handle 902 drives the movement of the slide bar 904, and at the same time compresses the spring 906. The movement of the slide bar 904 drives the clamping bar 905 to move to the left, so that the right ends of the clamping bar 905 and the slide bar 904 are flush with the outer wall of the second outer shell 901. At the same time, the operator pulls the right handle 902 to the right, so that the left ends of the clamping bar 905 and the slide bar 904 are flush with the outer wall of the second outer shell 901. Then another operator puts the blocking block 5 into the box body 10 from the bottom, observes through the through hole at the opened box door 13, and makes the blocking block 5 accurately enter the chute processed on the support plate 14. Then the operator releases the two handles 902, and uses the elasticity of the spring 906 to make the ends of the slide bar 904 and the clamping bar 905 abut against the inner wall of the groove processed on the blocking block 5. Subsequently, the box door 13 is closed. Sealing gaskets are provided at the joints of the box door 13 and the box body 10, so as to realize that different models of aluminum tubes can be processed by replacing different-sized blocking blocks 5, thereby reducing the working limitations.

[0033] Aluminum tube processing process:

[0034] An appropriate amount of liquefied aluminum is added into the box body 10 through the feed inlet 12. The hydraulic cylinder 8 is started, and the output end of the hydraulic cylinder 8 extends to drive the piston 6 to move downward, pressurizing the air in the box body 10, so that the liquid aluminum flows downward rapidly. At the same time, part of the liquid aluminum adhering to the inner wall of the box body 10 is separated from the inner wall of the box body 10, and a mold is formed with the through hole at the bottom of the box body 10 and the blocking block 5, so that the liquid aluminum forms an aluminum tube. The working principle of the liquid aluminum forming the aluminum tube is the same as that in the authorized announcement number "CN211331264U", and no more details will be described here.

[0035] Cooling process of the aluminum tube:

[0036] Start the power supply of the second motor 15. The output shaft of the second motor 15 rotates to drive the fan 13 to rotate. Then start the power supply of the first motor 202. The output shaft of the first motor 202 rotates forward to drive the upper toothed pulley 203 to rotate, thereby driving the toothed belt 204 and the lower toothed pulley 203 to rotate. The rotation of the toothed belt 204 drives the slider 205 to move downward, thereby driving the convex block 206 to slide downward along the inner wall of the frame body 207. When the convex block 206 moves downward to the maximum distance, reverse the output shaft of the first motor 202 to make the convex block 206 move upward and drive the slider 205 to move upward at the same time. The movement of the slider 205 drives the motor box 3 to move, and the movement of the motor box 3 drives the fan 13 to move. The operator controls the power supplies of the two first motors 202 to make the two fans 13 move back and forth alternately to uniformly cool the solidified aluminum tube, reducing the probability of unqualified aluminum tubes after processing, thereby improving the work quality. When the aluminum tube is cooled, the operator takes out the aluminum tube from the opening at the bottom of the box body 10.
