[0034] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0035] Please refer to the accompanying drawings Figure 1 , the accompanying drawings Figure 2 , the accompanying drawings Figure 5 and the accompanying drawings Figure 8 , the present embodiment provides a kind of automobile longitudinal beam forming die 10, including mounting seat 100, upper die 300, lower die 400, hydraulic cylinder 200, punch mounting seat 500 and locking device.

[0036] In the present embodiment, hydraulic cylinder 200 is fixedly installed at the upper end of mounting seat 100, upper die 300 is arranged at the upper portion of mounting seat 100, lower die 400 is installed at the upper end surface of punch mounting seat 500, upper die 300 and lower die 400 are arranged oppositely in up and down, the piston rod of hydraulic cylinder 200 is fixedly connected with upper die 300, for driving upper die 300 to move up and down.

[0037] Please refer to the accompanying drawings Figure 5 and the accompanying drawings Figure 8 , the upper end surface of punch mounting seat 500 is formed with a plurality of installation grooves 501, spherical support device 600 is installed in installation groove 501, spherical support device 600 is used to form rolling contact with the bottom end surface of lower die 400, to facilitate the movement of lower die 400 during installation and positioning on punch mounting seat 500. In some embodiments, installation groove 501 is four, four installation grooves 501 are formed around the upper end surface of punch mounting seat 500, and the number of corresponding spherical support device 600 is four.

[0038] Please refer to the accompanying drawings Figure 5 to the accompanying drawings Figure 8 , spherical support device 600 includes support seat 601, support steel ball 602 and retainer 604, support seat 601 is installed in installation groove 501, retainer 604 is fixedly installed on the upper end surface of support seat 601, and support steel ball 602 is rollingly installed in retainer 604, i.e. support steel ball 602 can roll relative to retainer 604. Specifically, retainer 604 limits the installation cavity of support ball from falling off, support steel ball 602 is rollingly installed in the installation cavity, and the specific shape of retainer 604 can refer to the outer shape structure of the existing centripetal ball bearing.

[0039] Please refer to the accompanying drawings Figure 2 and the accompanying drawings Figure 3As shown, after the spherical support device 600 is installed in place in the mounting groove 501, part of the support steel ball 602 protrudes from the upper groove surface of the mounting groove 501, such as 1 / 3 to 1 / 2 of the support steel ball 602 protrudes from the upper groove surface of the mounting groove 501, so that when the lower mold 400 moves relative to the punch mounting base 500, the bottom end surface of the lower mold 400 will directly contact the support steel ball 602, so that the movement of the lower mold 400 is a rolling movement. The bottom end surface of the lower mold 400 is provided with an arc-shaped groove that is fitted with the support steel ball 602, that is, after the lower mold 400 is positioned and installed on the punch mounting base 500, the protruding part of the support steel ball 602 from the groove surface of the mounting groove 501 is installed in the arc-shaped groove. The setting of the arc-shaped groove can make the arc-shaped groove coincide with the support steel ball 602 after the lower mold 400 is installed in place on the punch mounting base 500, so that at this time the lower mold 400 is difficult to move to the four directions through the support steel ball 602, which plays a limiting function on the lower mold 400, and ensures the stability of the position of the lower mold 400 after installation.

[0040] Referring to the accompanying drawings Figure 3 and the accompanying drawings Figure 4 As shown, after the lower mold 400 is hoisted to the upper end surface of the punch mounting base by means of a forklift or a travelling crane, etc., the subsequent positioning and installation of the lower mold 400 needs to be adjusted and installed by hand. For example, in the accompanying drawings Figure 3 and the accompanying drawings Figure 4 In order to avoid the arc-shaped groove on the left side of the bottom end surface of the lower mold 400 coinciding with the support steel ball 602 on the right side of the punch mounting base 500 during the movement adjustment of the lower mold 400, the lower mold 400 is difficult to continue to move forward along the movement direction at this time, resulting in that part (the right side part) of the lower mold 400 is still located outside the punch mounting base 500; for this, refer to the accompanying drawings Figure 4As shown, when the lower mold 400 is installed, the lower mold 400 can be pushed laterally (to the rear side or the front side) by a certain distance, so that the arc-shaped groove on the lower mold 400 is not on the same axis as the corresponding installed supporting steel ball 602, but the bottom end surface of the lower mold 400 is in contact with the supporting steel ball 602 installed on the punch mounting seat 500. In this way, during the movement adjustment of the lower mold 400, the arc-shaped groove on the lower mold 400 will not cause the lower mold 400 to be difficult to move and adjust because it is clamped on the supporting steel ball 602 in the wrong orientation. When the lower mold 400 moves to the appropriate position, such as when the arc-shaped groove on the bottom end surface of the lower mold 400 is on the same axis as the corresponding supporting steel ball 602 on the punch mounting seat 500 in the lateral direction, the lower mold 400 is moved laterally so that the arc-shaped groove on the bottom end surface of the lower mold 400 corresponds to sliding into the position of the corresponding supporting steel ball 602 on the punch mounting seat 500. At this time, due to the matching between the arc-shaped groove and the supporting steel ball 602, the arc-shaped groove restricts the movement of the supporting steel ball 602 in the four directions. Finally, the lower mold 400 is fixedly installed on the punch mounting seat 500 by the locking device (locking bolt), and the installation of the lower mold 400 on the punch mounting seat 500 is completed.

[0041] When the lower mold 400 is installed by introducing the spherical supporting device 600 on the punch mounting seat 500, the installation work can be easily and conveniently performed. In addition, since the lower mold 400 can be moved only with a small force, not only the fatigue degree of the work can be reduced, but also the danger of the worker can be reduced.

[0042] Referring to the accompanying drawings Figure 6 and the accompanying drawings Figure 8 As shown, in some embodiments, the automobile beam forming mold further comprises a load sensor 700 and a control unit, the load sensor 700 is horizontally installed on the supporting seat 601, and the load sensor 700 is in communication with the control unit. It should be noted that the function of the load sensor 700 in the present embodiment is only to sense the load size borne by the supporting steel ball 602, and the load sensor 700 and the control unit can be selected from the commonly used load sensor and control system products on the market. The load sensor is built into the supporting seat 601 to detect the load value caused by the lower mold 400 applied to the supporting steel ball 602.

[0043] The control unit collects the load value detected by the load sensor, and in particular when the load value is higher or lower than other supporting steel balls 602, the height of the corresponding supporting seat 601 can be adjusted to correct the load value.

[0044] That is, when the height of the support seat 601 is adjusted, for example, the load applied to the support steel ball 602 does not reach the preset value, the height adjustment unit on the corresponding support seat 601 is adjusted to increase the height of the support seat 601 and the support steel ball 602, so as to achieve load distribution.

[0045] On the contrary, when the load applied to a certain support steel ball 602 exceeds the preset value, the height adjustment unit on the corresponding support seat 601 is adjusted to reduce the height of the support seat 601 and the support steel ball 602, so as to achieve load distribution.

[0046] Referring to FIGS. 1 to 8, the height adjustment unit is installed on the opposite sides of the support seat 601, and the height adjustment unit is used to adjust the installation height of the support seat 601 in the installation groove 501.

Figure 6 Figure 7 As shown in FIGS. 1 to 8, the height adjustment unit is installed on the opposite sides of the support seat 601, and the height adjustment unit is used to adjust the installation height of the support seat 601 in the installation groove 501.

[0048] Referring to FIGS. 1 to 8, the height adjustment unit is installed on the opposite sides of the support seat 601, and the height adjustment unit is used to adjust the installation height of the support seat 601 in the installation groove 501. Figure 6 Figure 9 Specifically, as shown in FIGS. 1 to 8, the height adjustment unit includes a pair of height adjustment assemblies, and the pair of height adjustment assemblies are respectively arranged on the opposite sides of the support seat 601. Each height adjustment assembly includes an adjusting rod 605, a fixed seat 603, and a connecting lug 607. The fixed seat 603 is horizontally fixedly installed on the inner wall of the installation groove 501, and the fixed seat 603 is provided with a threaded hole. The connecting lug 607 is horizontally fixedly installed on one side of the support seat 601, and the connecting lug 607 is provided with a through hole coaxially arranged with the threaded hole. The outer periphery of the adjusting rod 605 is axially formed with an external thread 6051 threadedly connected with the threaded hole. The end of the adjusting rod 605 close to the terminal end is an optical axis part 6052.
