Description

Technical Field

[0001] This utility model belongs to the field of aluminum processing, and specifically relates to a pressure regulating device for an aluminum extrusion molding machine. Background Technology

[0002] In modern industrial production, aluminum is widely used in construction, transportation and other fields due to its excellent properties such as light weight, high strength and corrosion resistance. Aluminum extrusion molding is one of the important processes in aluminum processing. This process uses the pressure device of the aluminum extrusion molding machine to form the required shape through the mold.

[0003] During the aluminum extrusion process, some debris is inevitably generated. Ordinary extrusion equipment often lacks an effective debris discharge structure, causing debris to be easily squeezed onto the die surface. This accumulation of debris not only affects the precision and service life of the die but also increases the difficulty and cost of subsequent cleaning. If not cleaned in time, the debris may mix into the aluminum material during subsequent extrusion, causing surface scratches, defects, and other quality problems, affecting the quality and performance of the product. During the extrusion process, debris may splash onto the hydraulic cylinder and adhere to its surface. Long-term accumulation of debris will cause wear and corrosion to the hydraulic cylinder's seals, piston rods, and other components, affecting the normal operation of the hydraulic cylinder, reducing the reliability and stability of the equipment, and increasing maintenance costs and downtime. Utility Model Content

[0004] To overcome the problems of aluminum scraps being squeezed onto the mold and difficult to clean during use, and the scraps sticking to the hydraulic cylinder and potentially affecting its service life, a pressure regulating device for an aluminum extrusion molding machine is proposed.

[0005] The technical solution of this utility model is as follows: a pressure regulating device for an aluminum extrusion molding machine, comprising a bearing mechanism and an adjusting mechanism. The bearing mechanism includes a movable seat, and the adjusting mechanism is installed on the bearing mechanism. The adjusting mechanism includes a hydraulic cylinder, and an extrusion mechanism is installed on the adjusting mechanism. The extrusion mechanism includes an extrusion block. The output end of the hydraulic cylinder passes through the left end of the movable seat and is fixedly connected to the extrusion block. The left end of the extrusion block has several grooves that are equidistantly arranged around the perimeter. The outer wall of the extrusion block has several discharge ports that are equidistantly arranged around the perimeter. The discharge ports correspond one-to-one with the grooves and are connected. The right end of the extrusion block is fixedly connected to one end of a corrugated pipe. The corrugated pipe is sleeved on the outer wall of the output end of the hydraulic cylinder, and the other end of the corrugated pipe is fixedly connected to the left end of the movable seat.

[0006] Furthermore, the supporting mechanism also includes a base, and the left end of the base has a symmetrical sliding groove, in which a sliding rod is slidably mounted.

[0007] Furthermore, a movable seat is fixedly connected to the left end of the slide rod, and a limiting hole with equal left and right distances is opened at the upper end of the slide rod. A screw hole is opened through the inner edge of the upper end of the slide groove.

[0008] Furthermore, a screw is installed in the internal thread of the screw hole, and the screw passes through the screw hole and is installed in the limiting hole. Mounting holes are opened through the four corner edges of the upper end of the base.

[0009] Furthermore, a shock-absorbing pad is provided at the lower end of the base, and a screw hole is provided on the inner wall of the end of the base that is close to the movable seat. A screw hole is provided through the left and right ends of the hydraulic cylinder.

[0011] Furthermore, the variable pump is connected to the hydraulic cylinder pipeline, and a slot is opened at the center of the left end of the extrusion block, with a sensor fixedly connected inside the slot.

Compared with the existing aluminum extrusion molding machine adjusting device, the added extrusion mechanism can extrude the aluminum material by the extrusion block; the groove and discharge port on the extrusion block can discharge the debris generated by extrusion out of the mold surface; the corrugated pipe can protect the output end of the hydraulic cylinder, preventing debris from sticking to the output end of the hydraulic cylinder and affecting the service life of the hydraulic cylinder.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-5 This utility model provides an embodiment of a pressure regulating device for an aluminum extrusion molding machine, comprising a bearing mechanism 1 and an regulating mechanism 2. The bearing mechanism 1 includes a movable seat 102, and the regulating mechanism 2 is mounted on the bearing mechanism 1. The regulating mechanism 2 includes a hydraulic cylinder 201, and an extrusion mechanism 3 is mounted on the regulating mechanism 2. The extrusion mechanism 3 includes an extrusion block 301. The output end of the hydraulic cylinder 201 passes through the left end of the movable seat 102 and is fixedly connected to the extrusion block 301. The left end of the extrusion block 301 has several grooves 305 that are equidistantly arranged around it. The outer wall of the extrusion block 301 has several discharge ports 306 that are equidistantly arranged around it. The discharge ports 306 correspond one-to-one with the grooves 305 and are connected to them. The right end of the extrusion block 301 is fixedly connected to one end of a corrugated pipe 302. The corrugated pipe 302 is sleeved on the outer wall of the output end of the hydraulic cylinder 201, and the other end of the corrugated pipe 302 is fixedly connected to the left end of the movable seat 102.

[0021] The bearing mechanism 1 can support and fix the adjusting mechanism 2. The output end of the hydraulic cylinder 201 can drive the extrusion block 301 to adhere to and press the aluminum material, so that the aluminum material enters the mold to be extruded and formed. The groove 305 can guide the debris generated during extrusion to the discharge port 306. The discharge port 306 can discharge the debris from the gap between the extrusion block 301 and the mold, reducing the probability of debris being squeezed on the mold surface and reducing the problem of debris accumulation leading to a decrease in extrusion quality. The bellows 302 can contract and expand with the output end of the hydraulic cylinder 201 to protect the output end of the hydraulic cylinder 201 and prevent debris from sticking to the output end of the hydraulic cylinder 201, which would reduce the life of the hydraulic cylinder 201.

[0022] Please see Figure 3In this embodiment, the supporting mechanism 1 also includes a base 101. The left end of the base 101 is provided with a symmetrical sliding groove 103. A sliding rod 104 is slidably provided in the sliding groove 103. In use, the sliding rod 104 can slide along the inner wall of the sliding groove 103. The left end of the sliding rod 104 is fixedly connected to a movable seat 102. The upper end of the sliding rod 104 is provided with a limiting hole 105 that is equidistant from left to right. A screw hole 106 is provided through the edge of the upper inner wall of the sliding groove 103. In use, the movable seat 102 can slide left and right along the sliding groove 103 through the sliding rod 104, and the distance between the movable seat 102 and the base 101 can be adjusted to accommodate the installation of hydraulic cylinders 201 of different lengths.

[0023] Please see Figures 3-4 In this embodiment, a screw 107 is installed in the internal thread of screw hole 106. The screw 107 passes through screw hole 106 and is installed in the limiting hole 105. Mounting holes 110 are provided through the four corner edges of the upper end of the base 101. In use, the slide rod 104 can be fixed by the screw 107 to improve the stability of the movable seat 102 during operation. A shock-absorbing pad 108 is provided at the lower end of the base 101. A screw hole 109 is provided on the inner wall of the end of the base 101 that is close to the movable seat 102. Screw holes 203 are provided through the left and right ends of the hydraulic cylinder 201. In use, the base 101 can be installed on the work platform through the mounting holes 110. The shock-absorbing pad 108 can reduce the vibration transmission of the work platform to the base 101 and improve the stability of the base 101 during operation.

[0024] Please see Figures 4-5 In this embodiment, screw hole 203 corresponds one-to-one with screw hole 109. Hydraulic cylinder 201 is mounted on base 101 and movable seat 102 by bolts. Variable pump 202 is mounted on the right end of movable seat 102, and controller 204 is mounted on variable pump 202. In use, hydraulic cylinder 201 can be fixedly mounted on base 101 and movable seat 102 by bolts, improving the stability of hydraulic cylinder 201 during operation. Controller 204 can control variable pump 202 to control the hydraulic pressure of hydraulic cylinder 201. Variable pump 202 is connected to hydraulic cylinder 201 by pipeline. A slot 303 is opened at the center of the left end of extrusion block 301, and sensor 304 is fixedly connected in slot 303. In use, sensor 304 can measure the pressure between extrusion block 301 and aluminum material, facilitating the adjustment of hydraulic pressure of hydraulic cylinder 201 and improving extrusion molding quality.

[0025] During operation, firstly, adjust the sliding rod 104 according to the length of the hydraulic cylinder 201 to maintain a suitable distance between the movable seat 102 and the base 101. Then, fix the right end of the hydraulic cylinder 201 to the base 101 with bolts. Adjust the movable seat 102 so that the output end of the hydraulic cylinder 201 passes through the movable seat 102, and align the second screw hole 109 on the movable seat 102 with the third screw hole 203 on the hydraulic cylinder 201. Use bolts to fix the other end of the hydraulic cylinder 201 to the movable seat 102. Next, thread the screw 107 onto the screw... Inside hole 106, screw 107 passes through screw hole 106 and is fixed in the corresponding limiting hole 105, completing the installation of hydraulic cylinder 201. Then, extrusion block 301 and bellows 302 are fixed on the output end of hydraulic cylinder 201, connecting hydraulic cylinder 201 and variable pump 202. Wait for the aluminum material to pass through the mold. Finally, controller 204 controls variable pump 202 to adjust the hydraulic pressure of hydraulic cylinder 201, so that the output end of hydraulic cylinder 201 pushes extrusion block 301 to extrude aluminum material. Wait for extrusion block 301 to extrude aluminum material into shape.

[0026] Through the above steps, the bearing mechanism 1 can support and fix the adjusting mechanism 2, the output end of the hydraulic cylinder 201 can drive the extrusion block 301 to adhere to and press the aluminum material, the groove 305 can guide the debris generated during extrusion molding into the discharge port 306, the discharge port 306 can discharge the debris out of the gap between the extrusion block 301 and the mold, and the corrugated pipe 302 can contract and expand with the output end of the hydraulic cylinder 201 to protect the output end of the hydraulic cylinder 201. This solves the problem that aluminum material debris is squeezed on the mold and is not easy to clean when the adjusting device of the aluminum material extrusion molding machine is in use, and that debris sticking to the hydraulic rod may affect the service life of the hydraulic rod.
