Description

Technical Field

[0001] This utility model belongs to the field of extrusion press technology, and in particular relates to a detection and pushing mechanism and an extrusion press. Background Technology

[0002] Extrusion molding is a common forming method for aluminum alloy tubes and rods. Extrusion molding requires the use of an extrusion press to achieve its production. Most existing extrusion presses use forward extrusion. In forward extrusion, the extrusion shaft is hydraulically driven to push the cast ingot forward in the extrusion cylinder, forcing it to be extruded from the die to form tubes and rods.

[0003] During the conveying of aluminum bars, the aluminum bars need to be pushed to the detection device for detection and positioning first using a pusher assembly. Then, the aluminum bars are gradually moved to the extrusion station by the piston cylinder at the detection device. However, in the actual production process, the piston rod and cylinder body of the piston cylinder are too large, resulting in the overall space occupied by the equipment being too large. Utility Model Content

[0004] The purpose of this invention is to provide a detection and feeding mechanism and an extruder to solve the problem that conventional piston cylinders in the prior art result in excessive space occupation of the equipment.

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] In a first aspect, a detection and feeding mechanism is provided, comprising a detection frame, a first support portion, a second support portion, a rodless cylinder, and a first sensing portion, wherein:

[0007] The first support portion and the second support portion are symmetrically arranged on the testing frame. Both the first support portion and the second support portion are inclined to form a channel for the aluminum rod to move. The fixed end of the rodless cylinder is installed on the testing frame. The first sensing portion is installed on the driving end of the rodless cylinder. The driving end of the rodless cylinder is movably arranged on the testing frame along the channel. The rodless cylinder is configured to drive the first sensing portion to move along a first direction, so as to push the aluminum rod from the first end of the channel to the second end of the channel through the first sensing portion. The first sensing portion is configured to sense whether the aluminum rod is placed at the first end of the channel.

[0008] Furthermore, both the first support portion and the second support portion are provided with a plurality of conveying rollers spaced apart along the first direction, and each conveying roller is rotatably disposed on the corresponding support portion along its own axis.

[0009] Furthermore, the testing frame is provided with a second sensing unit, which is configured to position the movement stroke of the aluminum rod when the aluminum rod is pushed back.

[0010] Furthermore, the first sensing part is a contact sensing shaft, which extends along a first direction.

[0011] Furthermore, the bottom of the contact sensing shaft is mounted on a slider, which is sleeved on the drive end of the rodless cylinder. The rodless cylinder drives the slider to move laterally, thereby causing the contact sensing shaft to move laterally.

[0012] Furthermore, both the first support portion and the second support portion include a support base and a plurality of mounting shafts, each mounting shaft corresponding to one conveying roller. The support base is provided with a clearance groove extending in a first direction. All the mounting shafts are mounted on the support base and pass through the clearance groove. Each conveying roller can be rotatably mounted on the corresponding mounting shaft.

[0013] In one aspect, an extruder is provided, which includes the aforementioned detection and pushing mechanism.

[0014] Compared with the prior art, the beneficial effects of the aforementioned detection and feeding mechanism and extruder are as follows:

[0015] 1) Through the cooperation of the first support part, the second support part, the rodless cylinder and the first sensing part, the rodless cylinder drives the first sensing part to move along the first direction, and the first sensing part pushes the aluminum rod from the first end of the channel to the second end of the channel. The first sensing part senses whether an aluminum rod is placed at the first end of the channel. The use of a rodless cylinder with a guide rod not only reduces equipment cost and space, greatly reducing the size of the equipment, but also makes the cylinder less prone to bumps and collisions, making it safer and more reliable.

[0016] 2) By setting a second sensing unit, the second sensing unit positions the movement of the aluminum rod when it is pushed back, thereby achieving precise positioning of the movement of the aluminum rod and improving the accuracy of the movement of the aluminum rod.

[0023] Please see Figures 1 to 3 As shown, in this embodiment, a detection feeding mechanism and extruder include a detection frame 10, a first support 20, a second support 30, a rodless cylinder 40, and a first sensing unit 50. The first support 20 and the second support 30 are symmetrically arranged on the detection frame 10. Both the first support 20 and the second support 30 are inclined to form a channel 21 for the aluminum rod 100 to move. The fixed end of the rodless cylinder 40 is mounted on the detection frame 10. The first sensing unit 50 is mounted on the driving end of the rodless cylinder 40. The driving end of the rodless cylinder 40 is movably arranged on the detection frame 10 along the channel 21. The rodless cylinder 40 is configured to drive the first sensing unit 50 along a first direction (…). Figure 1 The first sensing unit 50 moves the aluminum rod 100 from the first end of the channel 21 to the second end of the channel 21 via the first sensing unit 50. The first sensing unit 50 is configured to sense whether the aluminum rod 100 is placed at the first end of the channel 21.

[0024] As can be seen, through the cooperation of the first support part 20, the second support part 30, the rodless cylinder 40 and the first sensing part 50, the rodless cylinder 40 drives the first sensing part 50 to move along the first direction, and the first sensing part 50 pushes the aluminum rod 100 from the first end of the channel 21 to the second end of the channel 21. The first sensing part 50 senses whether the aluminum rod 100 is placed at the first end of the channel 21. The use of the rodless cylinder 40 with a guide rod not only reduces the equipment cost and makes the space compact, greatly reducing the size of the equipment, but also makes the cylinder less prone to bumps and collisions, making it safer and more reliable.

[0025] In one embodiment, both the first support portion 20 and the second support portion 30 are provided with a plurality of conveying rollers 22 spaced apart along a first direction, and the first support portion 20 and the second support portion 30 are arranged along a second direction. Figure 2 The conveying rollers 22 are spaced apart in the Y direction, and each conveying roller 22 is rotatably mounted on its corresponding support along its own axis.

[0026] As can be seen, by setting the conveyor rollers 22, when the aluminum rod 100 moves in the channel 21, the outer periphery of the aluminum rod 100 abuts against the multiple conveyor rollers 22, and the aluminum rod 100 can be moved by rolling friction, providing a support part with good conveying effect and high stability.

[0027] In one embodiment, the testing frame 10 is provided with a second sensing unit 60, which is configured to position the movement stroke of the aluminum rod 100 when the aluminum rod 100 is pushed back.

[0028] It should be noted that if the detection device detects that the heating temperature of the aluminum rod 100 has not reached the preset temperature, the external push assembly will push the aluminum rod 100 back to the channel 21 and move it to the initial position. The second sensing unit 60 on the detection frame 10 positions the movement of the aluminum rod 100.

[0029] Specifically, the second sensing unit 60 is a magnetic switch.

[0030] Of course, as another implementation, the second sensing unit 60 can also be a proximity switch or a displacement sensor.

[0031] It can be seen that by setting the second sensing unit 60, the second sensing unit 60 can position the movement stroke of the aluminum rod 100 when the aluminum rod 100 is pushed back, thereby achieving precise positioning of the movement stroke of the aluminum rod 100 and improving the movement accuracy of the aluminum rod 100.

[0032] In one embodiment, the first sensing part 50 is a contact sensing shaft that extends along a first direction.

[0033] It can be seen that by setting the first sensing part 50 as a contact sensing shaft, the contact sensing shaft structure is relatively simple, easy to install and maintain, and can work stably in a limited space. When used in conjunction with the rodless cylinder 40 with a guide rod, it can save movement space and improve the overall space utilization.

[0034] In one implementation, the bottom of the contact sensing shaft is mounted on the slider 51, which is sleeved on the drive end of the rodless cylinder 40. The rodless cylinder 40 drives the slider 51 to move laterally, thereby causing the contact sensing shaft to move laterally.

[0035] As can be seen, by setting the slider 51, the rodless cylinder 40 drives the slider 51 to move laterally, which in turn drives the contact induction shaft to move laterally, providing a transmission structure with a simple structure and high sliding accuracy.

[0036] In one embodiment, both the first support portion 20 and the second support portion 30 include a support base 23 and a plurality of mounting shafts 24. Each mounting shaft 24 corresponds to a conveying roller 22. The support base 23 is provided with a clearance groove 230 extending in a first direction. All the mounting shafts 24 are mounted on the support base 23 and pass through the clearance groove 230. Each conveying roller 22 can be rotatably mounted on the corresponding mounting shaft 24.

[0037] Based on the above-described detection and feeding mechanism, an extruder is provided, including the above-described detection and feeding mechanism.

[0038] When the above-mentioned detection and pushing mechanism is working: the external pushing component pushes the aluminum rod 100 to the first end of the channel 21, the aluminum rod 100 abuts against the contact sensing shaft, the rodless cylinder 40 drives the first sensing part 50 to move along the first direction, and the first sensing part 50 pushes the aluminum rod 100 from the first end of the channel 21 to the second end of the channel 21, so that the aluminum rod 100 moves to the extrusion station. If the detection device detects that the heating temperature of the aluminum rod 100 has not reached the preset temperature, the external push component will push the aluminum rod 100 back to the channel 21 and move it to the initial position. The second sensing part 60 on the detection frame 10 positions the movement stroke of the aluminum rod 100.

[0039] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
