Abstract
Description
Technical Field
[0001] This utility model relates to the field of extrusion press structure technology, and in particular to a moving device for an extrusion press and an extrusion press including the device. Background Technology
[0002] An extrusion press generally includes a frame and a front beam, a rear beam, a movable beam, and a billet cylinder mounted on the frame. The billet cylinder and the movable beam are located between the front beam and the rear beam and can slide on the frame to complete actions such as feeding, pressing, and extrusion forming.
[0003] The existing moving device includes two guide rails, on which the ingot-holding cylinder is mounted. A slide is located at the bottom of the ingot-holding cylinder, and a copper plate is placed between the slide and the guide rails. The copper plate directly contacts and rubs against the guide rails, resulting in rapid wear, short-term maintenance of equipment accuracy, frequent adjustments, and potential disruptions to production schedules. Utility Model Content
[0004] The main purpose of this invention is to propose a moving device for an extruder, which aims to solve the technical problem of rapid wear of copper plates in the prior art, which affects the production progress.
[0005] To achieve the above objectives, this utility model proposes a moving device for an extruder, including a guide rail and a slide block disposed on the guide rail. A sliding plate is provided between the guide rail and the slide block, and the sliding plate is fixed on the slide block and abuts against the guide rail. The slide block is also provided with a rolling device, which includes a roller. The slide block presses the roller onto the guide rail, and the roller and the sliding plate together support the slide block and the equipment disposed on the slide block.
[0006] The beneficial effects of this invention are as follows: When supporting equipment, the moving device places the equipment on a slide, and the weight of the slide and the equipment is jointly borne by the rollers and the sliding plate. Compared to moving devices that rely solely on the sliding plate to bear the entire weight of the slide and the equipment, the moving device in this invention experiences less friction on the sliding plate, resulting in less wear. Furthermore, the rollers and the sliding plate provide mutual protection, allowing the equipment to maintain its precision for a longer period, reducing the frequency of sliding plate adjustments, and ultimately improving production efficiency and extending the service life of the sliding plate and the moving device.
[0007] Preferably, the rolling device further includes a roller support structure, on which the roller is mounted. The slide block presses the roller onto the guide rail through the roller support structure, which helps to enhance the load-bearing capacity of the rolling device and extend its service life.
[0008] Preferably, the roller support structure includes an elastic support structure, the upper end of which is connected to the slide block, and the lower end of which is connected to the roller. This helps to further extend the service life of the equipment, prolong the time for maintaining accuracy, and reduce the frequency of adjustment and maintenance.
[0009] Preferably, the elastic support structure includes a disc spring assembly, which comprises multiple disc springs stacked together. Extruders typically have heavy equipment; disc springs have high stiffness and low deformation, ensuring both load-bearing capacity and the precision of equipment movement.
[0010] Preferably, the roller support structure includes a pneumatic device, and the roller is mounted on the pneumatic device.
[0011] Preferably, the roller support structure includes a hydraulic device, and the roller is mounted on the hydraulic device.
[0012] Preferably, the slide is provided with a roller assembly, which includes multiple rollers. The slide is provided with multiple slide plates and multiple roller assemblies. The multiple slide plates and multiple roller assemblies are arranged alternately along the direction of the guide rail, which is beneficial to evenly distribute the pressure of the equipment on the slide plates and rollers.
[0013] Preferably, the skateboard is made of copper alloy.
[0014] Preferably, the equipment moving device includes two guide rails arranged side by side at intervals, and two sliding grooves are provided on both sides of the lower end of the slide block. The two sliding grooves correspond one-to-one with the two guide rails. The slide plate and the roller are both provided on the upper surface of the sliding groove and pressed against the upper surface of the guide rail by the slide block. The equipment moving device also includes a side slide plate and a side roller. The side slide plate and the side roller are both provided on the side of the sliding groove and abut against the side of the guide rail, which helps to reduce the friction between the side slide plate and the side of the guide rail, and the equipment moves more smoothly.
[0015] This utility model also proposes an extrusion press, including the above-mentioned equipment moving device, as well as a frame and a billet cylinder, with guide rails disposed on the frame and slides disposed on the billet cylinder. Attached Figure Description

[0030] like Figures 1 to 7 As shown, a moving device for an extruder includes a guide rail 1 and a slide 2 mounted on the guide rail 1. A slide plate 3 is provided between the guide rail 1 and the slide 2. The slide plate 3 is fixed to the slide 2 and abuts against the guide rail 1. The slide 2 is also provided with a rolling device 4, which includes a roller 411. The slide 2 presses the roller 411 onto the guide rail 1. The roller 411 and the slide plate 3 together support the slide 2 and the equipment mounted on the slide 2.
[0031] When supporting equipment, the moving device places the equipment on the slide 2, and the weight of the slide 2 and the equipment is jointly borne by the rollers 411 and the sliding plate 3. Compared with moving devices that rely solely on the sliding plate 3 to bear the entire weight of the slide 2 and the equipment, the moving device of this invention experiences less friction on the sliding plate 3, resulting in less wear on the sliding plate 3. Furthermore, the rollers 411 and the sliding plate 3 provide mutual protection, allowing the equipment to maintain its accuracy for a longer period, reducing the frequency of adjusting the sliding plate 3, and ultimately improving production efficiency and extending the service life of the sliding plate 3 and the moving device.
[0032] In some specific embodiments, reference is made to Figures 4 to 6 The rolling device 4 also includes a roller support structure. The roller 411 is mounted on the roller support structure. The slide block 2 presses the roller 411 onto the guide rail 1 through the roller support structure, which helps to enhance the bearing capacity of the rolling device 4 and extend the service life of the rolling device 4.
[0033] Specifically, the roller 411 is located on the lower side of the slide block 2. The roller support structure provides vertical support for the roller 411. When the slide block 2 presses down on the roller 411, the roller support structure provides a certain support force to protect the roller 411 and extend its service life.
[0034] In some other embodiments, the roller 411 is mounted on the slide 2 via a horizontally extending rotating shaft, as long as it can be rotatably mounted on the slide 2 and can support the slide 2.
[0035] In some specific embodiments, reference is made to Figure 4 The roller support structure includes an elastic support structure 42, the upper end of which is connected to the slide block 2, and the lower end of which is connected to the roller 411.
[0036] In this embodiment, the slide 2 applies pressure to the roller 411 through the elastic support structure 42. The elastic support structure 42 has a compression limit. When the weight of the slide 2 and the equipment on it is too large, causing the elastic support structure 42 to reach its compression limit, the pressure that the roller 411 can withstand also reaches its maximum value. At this time, the sliding plate 3 will bear more pressure, providing overload protection for the roller 411. For example, in the equipment moving device of this embodiment, the roller 411 can withstand a maximum force of two tons. Before the pressure on the roller 411 reaches its maximum, the roller 411 and the sliding plate 3 each bear 50% of the weight. Therefore: if the weight of the slide 2 and the equipment reaches four tons, the roller 411 and the sliding plate 3 each bear a force of two tons; if the weight of the slide 2 and the equipment reaches five tons, the roller 411 bears a force of two tons, and the sliding plate 3 bears a force of three tons.
[0037] This design allows the roller 411 to slow down the wear rate of the slide plate 3, while the slide plate 3 can also bear more weight when necessary to protect the roller 411, thus extending the service life of the roller 411. The mutual protection design between the roller 411 and the slide plate 3 further extends the service life of the moving device in this embodiment, prolongs the time for maintaining accuracy, and reduces the frequency of adjustment and maintenance.
[0038] In some specific embodiments, reference is made to Figure 4 The elastic support structure 42 includes a disc spring assembly 421, which comprises multiple disc springs stacked together. Extruders are typically heavy equipment; disc springs have high stiffness and low deformation, ensuring both load-bearing capacity and the precision of equipment movement.
[0039] Disc springs have advantages such as short stroke, high load capacity, and small space requirement. They are also easy to maintain and replace, and have a long service life. This helps to reduce the manufacturing cost of moving devices, reduce maintenance time and frequency, and improve production efficiency.
[0040] In some other embodiments, the elastic support structure 42 includes a spring.
[0041] In some specific embodiments, reference is made to Figure 5 The roller support structure includes a pneumatic device 43, and the roller 411 is mounted on the pneumatic device 43.
[0042] Specifically, the pneumatic device 43 includes a cylinder. By adjusting the intake air pressure, the pressure of the cylinder piston rod on the roller 411 can be adjusted.
[0043] In this embodiment, the slide 2 applies pressure to the roller 411 through a cylinder. The maximum pressure that the roller 411 can withstand can be adjusted by adjusting the air intake pressure of the cylinder, achieving an effect similar to that of supporting the roller 411 with a spring support structure as described above. This can provide overload protection for the roller 411 and extend its lifespan.
[0044] In some specific embodiments, reference is made to Figure 6 The roller support structure includes a hydraulic device 44, and the roller 411 is mounted on the hydraulic device 44.
[0045] Specifically, the hydraulic device 44 includes a cylinder. By adjusting the inlet oil pressure, the pressure of the piston rod of the cylinder on the roller 411 can be adjusted.
[0046] In this embodiment, the slide 2 applies pressure to the roller 411 through the hydraulic cylinder. The maximum pressure that the roller 411 can withstand can be adjusted by adjusting the oil inlet pressure of the hydraulic cylinder, achieving an effect similar to that of supporting the roller 411 with the spring support structure described above. This can provide overload protection for the roller 411 and extend its lifespan.
[0047] In some specific embodiments, reference is made to Figure 3 and Figure 5 The slide 2 is provided with a roller assembly 41, which includes multiple rollers 411. The slide 2 is provided with multiple slide plates 3 and multiple roller assemblies 41. The multiple slide plates 3 and multiple roller assemblies 41 are arranged alternately along the direction of the guide rail 1, which is conducive to evenly distributing the pressure of the equipment on the slide plates 3 and rollers 411.
[0048] In some specific embodiments, the slide plate 3 is made of copper alloy.
[0049] In some other embodiments, the slide plate 3 is made of aluminum alloy.
[0050] In some other embodiments, the slide plate 3 may also be made of other wear-resistant alloys.
[0051] In some specific embodiments, reference is made to Figure 2 The equipment moving device includes two guide rails 1 arranged side by side at intervals. The two sides of the lower end of the slide block 2 are provided with slide grooves 21, and the two slide grooves 21 correspond one-to-one with the two guide rails 1. The slide plate 3 and the roller 411 are both provided on the upper surface of the slide groove 21 and are pressed onto the upper surface of the guide rail 1 by the slide block 2. The equipment moving device also includes a side slide plate 5 and a side roller 6. The side slide plate 5 and the side roller 6 are both provided on the side of the slide groove 21 and abut against the side of the guide rail 1.
[0052] In actual operation, the side of the slide 21 will also rub against the side of the guide rail 1. Therefore, the side slide plate 5 and side roller 6 are set on the side of the slide 21 to reduce the friction between the side slide plate 5 and the side of the guide rail 1, so that the equipment moves more smoothly.
[0053] refer to Figure 8 This embodiment also proposes an extrusion press, including the above-mentioned equipment moving device, and further including a frame 10, a billet cylinder 20 and a movable beam 30. The guide rail 1 is provided on the frame 10, and the billet cylinder 20 and the movable beam 30 are both provided with slides 2.
[0054] In addition to the billet cylinder 20 and the movable beam 30, some extruders may also be equipped with other devices that need to be moved during operation. These devices can also be moved relative to the frame 10 via the aforementioned device moving mechanism.
[0055] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
