[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-speed stamping automotive seat slide rail production device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-speed stamping production device for automotive seat slide rails includes a closed-type double-point press. The closed-type double-point press has a stamping slot on its inner side, and a stamping head is slidably mounted on the upper side of the stamping slot. A mold assembly is arranged inside the stamping slot. The mold assembly includes an upper pressure plate and a lower template. A stamping groove is formed in the middle of the upper pressure plate. A pressure-bearing protrusion is fixedly connected to the upper side of the lower template. A cavity is formed inside the pressure-bearing protrusion. Several stiffening ribs are evenly distributed and fixedly connected inside the cavity. Electromagnetic columns are arranged between the stiffening ribs and are fixedly installed inside the cavity.

[0008] Furthermore, the upper pressure plate, lower template, and pressure-bearing protrusion are all made of high-strength cast iron.

[0009] Furthermore, a mounting ear plate is fixedly connected to the side of the upper pressure plate, and the mounting ear plate is screwed onto the bottom of the stamping head.

[0010] Furthermore, mounting side plates are fixedly connected to both ends of the lower template, and the mounting side plates are screwed to the side wall of the closed double-point press.

[0011] Furthermore, a plate to be stamped is placed on top of the pressure-bearing protrusion, and four sets of stabilizing components are provided on both sides of the pressure-bearing protrusion.

[0015] Compared with related technologies, the high-speed stamping automotive seat slide rail production device proposed in this utility model has the following beneficial effects:

[0016] In this invention, a high-speed stamping automotive seat slide rail production device is described. Through a mold assembly, a pressure-bearing protrusion is set on the upper side of the lower mold plate. Before stamping, the steel plate to be stamped needs to be placed on the pressure-bearing protrusion. Activating the electromagnet column set inside the pressure-bearing protrusion generates a magnetic field around it. Cast iron, as a ferromagnetic material, has high magnetic permeability and can be magnetized by the magnetic field generated by the electromagnet. The magnetized cast iron forms a large number of magnetic domains, and the arrangement direction of these domains changes with the applied magnetic field, thus making the cast iron exhibit magnetism. At this time, a magnetic attraction effect is generated on the outer side of the pressure-bearing protrusion, which can attract the steel plate onto it, maintaining its stability during stamping and enhancing its stability.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Reference Figures 1-7 A high-speed stamping production device for automotive seat slide rails includes a closed-type double-point press 1. A stamping slot 3 is provided inside the closed-type double-point press 1. A stamping head 4 is slidably mounted on the upper side of the stamping slot 3. A mold assembly 5 is provided inside the stamping slot 3. The mold assembly 5 includes an upper pressure plate 51 and a lower template 54. A stamping groove 52 is provided in the middle of the upper pressure plate 51. A pressure-bearing protrusion 55 is fixedly connected to the upper side of the lower template 54. A cavity 57 is provided inside the pressure-bearing protrusion 55. Several stiffening ribs 58 are evenly distributed and fixedly connected inside the cavity 57. Electromagnetic columns 59 are provided between the stiffening ribs 58 and are fixedly installed inside the cavity 57. A controller 2 is fixedly installed on the side wall of the closed-type double-point press 1.

[0027] Through the above-described configuration, the cavity 57 provides installation space for the electromagnet column 59, and the stiffening rib 58 improves the overall structural strength of the pressure-bearing protrusion 55, enabling the pressure-bearing protrusion 55 to resist impact pressure.

[0028] In this method, a plate 7 to be stamped is placed on top of the pressure-bearing protrusion 55. Four sets of stabilizing components 6 are provided on both sides of the pressure-bearing protrusion 55. The stabilizing components 6 include a fixing block 61, which is fixedly installed on the upper side of the stamping groove 3. A sleeve 62 is fixedly installed on the side of the fixing block 61. A sliding rod 64 is sleeved inside the sleeve 62. A roller 65 is rotatably installed on the upper end of the sliding rod 64. The roller 65 is in contact with the bottom of the plate 7 to be stamped.

[0029] With the above-mentioned arrangement, the roller 65 contacts the bottom of the plate 7 to be stamped, thus providing support between the bottom sides of the plate 7 to be stamped. When the plate 7 to be stamped is pressed down by the side, it will drive the roller 65 to move downwards, thereby driving the slide rod 64 to slide inwards towards the sleeve 62, and thus causing the roller 65 to move to the side and downwards. The roller 65 eliminates friction and scraping with the bottom of the plate 7 to be stamped through adaptive rotation. During the downward stamping process of the plate 7 to be stamped, the side roller 65 always provides support, making the plate 7 to be stamped more stable during the stamping process.

[0030] In this configuration, a bottom support rod 63 is fixedly connected between the bottom of the sleeve 62 and the fixing block 61.

[0031] By setting the bottom support rod 63 in the above manner, the structural support strength of the sleeve 62 is improved.

[0032] In this method, a spring 66 is fixedly connected between the bottom of the slide rod 64 and the bottom of the inner side of the sleeve 62. A limit block 68 is fixedly installed on the side wall of the slide rod 64, and a sliding groove 67 is provided on the side wall of the sleeve 62. The limit block 68 is slidably connected to the sliding groove 67.

[0033] With the above-mentioned setup, the spring 66 inside the sleeve 62, due to its rebound force, causes the slide rod 64 to drive the roller 65 at its upper end to always abut against the bottom of the plate 7 to be stamped.

[0034] In this method, the upper pressure plate 51, the lower template 54, and the pressure-bearing protrusion 55 are all made of high-strength cast iron.

[0035] With the above-mentioned design, high-strength cast iron has relatively good toughness, which makes it less prone to brittle fracture when subjected to impact loads. Compared with ordinary cast iron, it can absorb more energy.

[0036] In this method, the upper pressure plate 51 is fixedly connected to the side of the mounting ear plate 53, which is screwed to the bottom of the punch head 4. The lower template 54 is fixedly connected to both ends of the mounting side plate 56, which is screwed to the side wall of the closed double-point press 1.

[0037] With the above-described configuration, both the upper pressure plate 51 and the lower template 54 can be screwed off, which facilitates later maintenance or replacement.

[0038] The working principle of the high-speed stamping automotive seat slide rail production device provided by this utility model is as follows:

[0039] In use, the sheet metal 7 to be stamped is placed above the pressure-bearing protrusion 55 of the mold assembly 5. At this time, the rollers 65 in the four sets of stabilizing components 6 on both sides of the pressure-bearing protrusion 55 are in contact with the bottom of the sheet metal 7 to be stamped, providing initial support for the sheet metal. The controller 2 activates the electromagnet column 59 set in the inner cavity 57 of the pressure-bearing protrusion 55. After the electromagnet column 59 is energized, it generates a magnetic field. Since the pressure-bearing protrusion 55 is made of high-strength cast iron, and cast iron is a ferromagnetic material, it will be magnetized in the magnetic field. The arrangement of the magnetic domains inside the magnetized cast iron changes, and the whole exhibits magnetism, which causes the outer side of the pressure-bearing protrusion 55 to generate a magnetic attraction, firmly adhering the sheet metal 7 to be stamped to its surface, enhancing the sheet metal's stamping performance. To ensure stability during the process, the closed-type double-point press 1 is started. The punch head 4 slides downward along the punching groove 3 under the drive of the press. The upper pressure plate 51, which is screwed to the bottom of the punch head 4 through the mounting ear plate 53, moves downward accordingly. When the punch head 4 moves to the position of the plate 7 to be punched, the punching groove 52 in the middle of the upper pressure plate 51 and the pressure-bearing protrusion 55 on the upper side of the lower template 54 cooperate with each other to perform the punching operation on the plate 7 to be punched. During the punching process, the side of the plate 7 to be punched will move downward under the punching force. At this time, the stabilizing component 6 plays a role. The downward movement of the plate drives the roller 65 to move diagonally downward. After the punching operation is completed, the punch head 4 is reset upward under the drive of the closed-type double-point press 1. The operator turns off the electromagnet column 59 via controller 2. At this time, the magnetic attraction of the pressure-bearing protrusion 55 disappears, and the stamped car seat slide rail can be removed from the mold assembly 5. At the same time, the roller 65 in the stabilizing assembly 6 returns to its initial position under the action of the spring 66, ready to receive the next stamping operation.
