Description

Technical Field

[0001] The present invention relates to the field of pipe cutting equipment, and in particular to a pipe beam cutting equipment. Background Art

[0002] In the body structure of an automobile, the A-pillar of the body is usually made of a hollow tube beam to reduce the total weight of the body. With the development of technology, various structures of the tube beam have appeared, such as a tube beam with a trapezoidal cross-section or a tube beam with a triangular cross-section.

[0003] After being manufactured and formed by specialized equipment, the pipe beam needs to undergo steps such as bending and cutting. Most existing pipe beam cutting methods are thermal cutting. For example, the invention patent with publication number CN109500615A, "A continuous forming device for forming a connecting column on an automobile," discloses a method for manufacturing an automobile A-pillar. In this patent document, after the A-pillar pipe beam is formed, the pipe is cut using a laser (thermal cutting) process. In the prior art, most pipe beam cutting methods also use thermal cutting. However, the use of thermal cutting has certain problems. The cross-section of the pipe beam will deform due to the high temperature, resulting in granular and uneven protrusions, which affect the smoothness of the cross-section. In addition, high-temperature cutting will cause a certain amount of oxidation on the cross-section of the pipe beam. When the body frame is assembled, it is necessary to weld the cross-section again. Due to the oxidation caused by the previous high-temperature cutting, the fixing strength may be weakened after welding, posing a safety hazard. Therefore, in subsequent research and development, the pipe beam is still cut using the cold cutting process.

[0004] The existing cold cutting process generally uses a cutting device with a tool to cut the pipe beam, but most of the cutting devices in the existing technology are rotary tools, which are prone to produce burrs at the incision during cutting. In addition, the cutting device in the existing technology does not have enough fixing force on the pipe beam during cutting, which easily produces beveled cut surfaces, affecting product quality.

[0045] like Figure 1 、 8 As shown, the embodiment of the present invention provides a pipe beam cutting device, comprising: a base plate 1 and a support structure 2 vertically installed on the base plate 1, as shown in FIG. Figure 2 As shown, the base plate 1 is a rectangular plate placed on the ground or fixed on other mounting structures. The support structure 2 is specifically a support plate with a plurality of mounting holes formed on the plate. The support structure 2 (support plate) is perpendicular to the surface of the base plate 1 and fixed to the center of the upper surface of the base plate 1. A first cutting groove 21 for the cutting tool 31 to pass through is formed in the middle of the support structure 2 (support plate).

[0046] The support structure 2 (support plate) divides the upper portion of the base plate 1 into two left and right areas, such as Figure 7 As shown, the left area ( Figure 7 The side indicated by the reference numeral a in the figure) is provided with a clamping mechanism 4, and the right side area ( Figure 7 A cutting mechanism 3 is provided on the side indicated by the reference numeral b in the figure;

[0047] like Figure 8 As shown, the clamping mechanism 4 includes a clamp 41 arranged opposite to each other and a driving mechanism 42 facing the clamp 41 and controlling its opening and closing; the cutting mechanism 3 includes a tool 31 with a blade and a power mechanism 32 driving the tool 31; the clamping mechanism 4 fixes the pipe beam, and then the cutting mechanism 3 cuts the pipe beam;

[0048] like Figure 7 As shown: a first cutting groove 21 for a cutting tool 31 to pass through is formed in the center of the support structure 2 (support plate); the cutting tool 31 can be driven by a driving mechanism 42 to reciprocate toward the clamping mechanism 4 to cut the pipe beam clamped by the clamp 41;

[0050] In each embodiment of the present invention, the first clamp 411 and the second clamp 412 are arranged relative to each other in the vertical direction, so that the first clamp 411 and the second clamp 412 can be relatively close to each other or move away from each other; the first clamp 411 and the second clamp 412 clamp the pipe beam from the upper and lower directions; when the first clamp 411 and the second clamp 412 are closed, a channel for clamping the pipe beam and allowing the pipe beam to pass through is formed between them, and the channel fits the surface of the pipe beam and conforms to the cross-sectional shape of the pipe beam.

The most important advantage of this structure is that the first clamp 411 and the second clamp 412 can be provided with multiple cutting dies 401 or cutting die guards 402, which not only increases the clamping area of ​​the clamp 41, but also increases the stability of the clamping, can ensure the flatness of the cross-section of the pipe beam and reduce the defective rate; and the cutting die guard 402 can also be made of a material different from that of the cutting die 401. When feeding, it protects the cutting die 401 from the outside to avoid collision and scratches on the pipe beam.

[0088] like Figure 2 As shown: Figure 2 The two sets of cutting dies 401 and the cutting die guard 402 respectively arranged on the first fixture 411 and the second fixture 412 are respectively abutted against each other when the first fixture 411 and the second fixture 412 are closed, and the gap between the spaced cutting dies 401 forms a first cutting groove 21 for the tool 31 to pass through. Figure 2 When the first fixture 411 or the second fixture 412 is of other shapes, a groove is also formed thereon, and the gap between the groove and the cutting die 401 together forms the first cutting groove 21 for the cutting tool 31 to pass through.

The two feed cover plates 6 are spaced apart along the feeding direction of the pipe beam and are parallel to the cutting die 401. The feed cover plates 6 are provided with rectangular feed holes 61, which are connected to the passage formed when the clamping groove 404 is closed. The function of the feed cover plates 6 is to protect the cutting die 401 and the cutting die guard plate 402 on both sides along the feeding direction.

[0094] The side of the feed cover plate 6 away from the support structure 2 (support plate) ( Figure 1 、 2 The left side shown in the figure is connected to a pressing plate 7, which reinforces the overall installation structure on the side and can also protect the cutting die 401 and the cutting die guard 402; the pressing plate 7 is provided with a second cutting groove 71 opposite to the first cutting groove 21. In the present invention, the pressing plate 7 is divided into two upper and lower plates, which are provided with a second cutting groove 71 opposite to each other.

In the present invention, the power mechanism 32 is preferably a hydraulic cylinder, but can also be other equipment such as a cylinder.

[0100] like Figure 8As shown, a waste box 15 is provided next to the fixture 41. The waste box 15 is a hollow structure and is provided on the left side of the fixture 41. One end of the waste box 15 is connected to the pressure plate 7 and is connected to the first knife groove 21, the second knife groove 71, and the third knife groove 81, so that the iron filings brought out by the tool 31 each time they are cut can fall into the waste box 15. An air pump or other absorption device can be provided at the other end of the waste box 15 to suck in the iron filings.

At this time, the pipe beam to be cut is fed into the clamp 41 from the feed cover 6 and passes through the feed cover 6 at the other end. Then the driving mechanisms 42 corresponding to the first clamp 411 and the second clamp 412 work to push the first clamp 4 11 and the second clamp 412 are clamped toward each other, so that the pipe beam is stuck in the passage formed by the two clamping grooves 404; then the power mechanism 32 works, pushing the tool 31 toward the clamped pipe beam, cutting the pipe beam, and at the same time taking out the cutting waste along the movement direction of the tool 31 and sending the waste into the waste box 15; then the power mechanism 32 is reset, and the tool 31 retracts; the driving mechanism 42 of the first clamp 411 and the second clamp 412 is reset, and the cutting die 401 moves away from each other, completing the cutting of a section of the pipe beam, and repeating the above operation can complete the cutting work of multiple sections.
