[0002] In the process of processing and manufacturing iron plates, it is often necessary to form an arc surface on the iron plate surface. The existing arc surface of the iron plate is mainly formed by stamping. The existing stamping method mainly uses a punch head and a mold to bend the iron plate to form an arc surface.

[0003] Since stamping causes the iron plate to deform and sink inside the mold, there is an extrusion force between the iron plate and the mold, which makes it difficult to remove the iron plate sunken inside the mold. The staff needs to use external tools to remove it, which greatly reduces the efficiency of arc forming on the iron plate surface.

[0004] In addition, when the arc surface of the existing iron plate is formed, the staff needs to place them on the mold one by one. After the formed iron plate is removed from the mold, the arc surface forming operation of the next iron plate can be carried out. Therefore, there is a vacuum period in the arc surface forming operation of the iron plate, which further reduces the efficiency of the arc surface forming of the iron plate. Therefore, a arc surface forming mold for iron products with convenient demolding is proposed to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-5 A convenient demoulding arc surface forming mold for iron products, comprising a bottom plate 1, a top end of the bottom plate 1 is fixedly connected to an L-shaped support plate 2 arranged oppositely, a top end of the L-shaped support plate 2 is fixedly connected to a fixing seat 14, a surface of the fixing seat 14 is rotatably connected to an annular mold 13, a surface of the annular mold 13 is provided with a plurality of circumferentially distributed forming grooves 1301, and an inner wall of the annular mold 13 is provided with an inclined groove 1302 connected to the forming groove 1301;

[0023] It should be noted that: a plurality of forming grooves 1301 are provided on the surface of the annular mold 13, so that the forming operation of the next iron plate can be carried out without waiting for the formed iron plate to be taken out, thereby eliminating the vacuum period of arc forming on the surface of the iron plate;

[0024] It is worth noting that the arrangement of the inclined groove 1302 can push the ejection ball 18 into the opening when the annular groove rotates.

[0025] The surface of the annular mold 13 is fixedly connected to a magnetic table 12 symmetrical to the forming groove 1301. The arrangement of the magnetic table 12 can support the iron plate to be processed. At the same time, the magnetic attraction of the magnetic table 12 on the iron plate is used to realize the limit function of the iron plate, thereby ensuring the stability of the iron plate during the stamping process.

[0026] A sliding groove 1401 is provided inside the fixed seat 14, and an ejection assembly is provided inside the sliding groove 1401. An opening communicating with the sliding groove 1401 is provided at the bottom end of the fixed seat 14. The ejection assembly includes a sliding block 16 slidably connected inside the sliding groove 1401, an ejection rod 17 fixedly connected to the bottom end of the sliding block 16, and an ejection ball 18 fixedly connected to the bottom end of the ejection rod 17. The top end of the ejection ball 18 is fixedly connected to an ejection spring 15, and the top end of the ejection spring 15 is fixedly connected to the inner wall of the sliding groove 1401.

[0027] It should be noted that: when the annular mold 13 carries the formed iron plate and rotates to the opening position, under the elastic force of the ejection spring 15, the sliding block 16 drives the ejection ball 18 to quickly hit the iron plate, so that the iron plate can be ejected from the forming groove 1301, realizing the automatic demoulding function;

[0028] It is worth noting that: the surface of the ejection ball 18 is wrapped with a rubber layer to prevent the ejection ball 18 from forming a pit on the surface of the iron plate when it hits the iron plate; the setting of the limit plate can control the ejection distance of the ejection ball 18 to ensure that the inclined groove 1302 can push the ejection ball 18 into the inner side of the opening;

[0029] The top of the L-shaped support plate 2 is fixedly connected to a U-shaped support frame 6, and a stamping assembly is arranged at the top of the U-shaped support frame 6. The stamping assembly includes a cylinder 7 installed at the top of the U-shaped support frame 6 and a stamping head 5 fixedly connected to one end of the output shaft of the cylinder 7. The two side walls of the stamping head 5 are fixedly connected to auxiliary plates 8, and the inner wall of the sliding groove 1401 is fixedly connected to a baffle 19. The bottom end of the auxiliary plate 8 is fixedly connected to a telescopic rod 9, and an extrusion wheel 11 is installed at the bottom end of the telescopic rod 9. The surface of the telescopic rod 9 is wound with a limit spring 10;

[0030] It should be noted that: the cylinder 7 drives the punch head 5 to move downward, at which time the extrusion wheel 11 first contacts the iron plate, and then the punch head 5 continues to move downward to contact the iron plate, cooperating with the forming groove 1301, so that an arc surface is formed on the surface of the iron plate. The extrusion wheel 11 cooperates with the telescopic rod 9 and the limit spring 10 to prevent the two ends of the iron plate from warping.

[0031] Furthermore, an inner gear ring 4 is fixedly connected to one side of the fixing seat 14, a driving motor 3 is installed on the side wall of the L-shaped supporting plate 2, and one end of the output shaft of the driving motor 3 is fixedly connected to a driving gear meshing with the inner gear ring 4;

[0032] It should be noted that the driving motor 3 drives the driving gear to rotate, which in turn drives the inner gear ring 4 to rotate, and then drives the annular mold 13 to rotate, thereby achieving the function of changing the position of the forming groove 1301.

[0033] The driving motor 3 is of the prior art, and its model is JB5274-91. It can realize the function of driving the driving gear to rotate, and will not be described in detail here.

[0034] When the utility model is used, the iron plate to be formed is placed on the magnetic table 12, and then the cylinder 7 is turned on, and the cylinder 7 drives the punch head 5 to move downward. At this time, the extrusion wheel 11 first contacts the iron plate, and then the punch head 5 continues to move downward to contact the iron plate, and cooperates with the forming groove 1301 to form an arc surface on the surface of the iron plate. The extrusion wheel 11 cooperates with the telescopic rod 9 and the limit spring 10 to prevent the two ends of the iron plate from tilting;

[0035] Then, the cylinder 7 drives the punch head 5 to reset, and then the drive motor 3 is turned on. The drive motor 3 drives the drive gear to rotate, and then drives the annular mold 13 to rotate through the inner gear ring 4, so that the remaining vacant forming grooves 1301 can be rotated to the bottom of the punch head 5, so that there is no need to wait for the formed iron plate to be taken out, and the forming operation of the next iron plate can be carried out, thereby eliminating the vacuum period of the arc surface forming of the iron plate surface;

[0036] When the annular mold 13 rotates to the opening position with the formed iron plate, under the elastic force of the ejection spring 15, the sliding block 16 drives the ejection ball 18 to quickly hit the iron plate, so that the iron plate can be ejected from the forming groove 1301, realizing the automatic demoulding function, thereby greatly improving the forming efficiency of the arc surface of the iron plate.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
