Description

Technical Field

[0001] The utility model relates to the technical field of die fasteners, in particular to a pressing edge fixing device used for automobile die stamping. Background Art

[0002] Stamping dies are special process equipment used to process materials (metal or non-metal) into parts (or semi-finished products) during cold stamping. They are called cold stamping dies (commonly known as cold stamping dies). Stamping is a pressure processing method that uses a die installed on a press to apply pressure to the material at room temperature to separate or plastically deform it, thereby obtaining the desired parts.

[0003] The conventional stamping die edge fixing method is to clamp the die edge through multiple die fastener pressure plates, and the pressure plates are locked and limited by bolts. The locking installation of several pressure plates makes the die assembly operation more complicated, and the installation angle of the pressure plate is also locked and limited by nuts. During stamping, there is a possibility of loosening due to excessive impact force of the punch. Therefore, the poor stability of the die will affect the stamping accuracy. Utility Model Content

[0004] The utility model aims to provide a clamping fixing device for automobile die stamping, so as to solve the problem that the conventional stamping die clamping fasteners mentioned in the above background technology have poor installation stability and affect the stamping accuracy.

[0006] Preferably, a rubber anti-slip pad is provided at the central position of the top of the mounting platform.

[0007] Preferably, a pair of grooves for accommodating the rubber anti-slip pads are formed at the bottom of the slide bar.

[0008] Preferably, a limiting hole for sliding movement of the first bolt is formed on the top of the slide rod, a penetrating sliding hole is formed on the side wall of the slide rod, the bottom of the first bolt extends into the sliding hole, and a sliding block is fixedly mounted thereon.

[0009] Preferably, a plurality of limiting edges distributed in a circumferential manner are fixedly mounted on the side wall of the first bolt, and a positioning hole matched with the limiting edges is formed on the top of the pressing block.

[0010] Preferably, the elastic component is a spring sleeved on the first bolt, and two ends of the spring are in contact with the pressing block and the sliding rod respectively.

[0011] Preferably, the slide bar forms protrusions at both ends of the bottom of the main body in a manner that the slide bar can contact the side walls of the mounting platform.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model forms a mold fastener on the top of the mounting table through the cooperation of the sliding rod, the first bolt, the pressure block and the spring. Compared with the conventional mold fastener pressure plate, the utility model limits the angle of the pressure block and is suitable for various types of molds.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-Figure 4The utility model provides a technical solution: a pressure edge fixing device for automobile mold stamping, comprising a mounting platform 1 and a pair of slide bars 2 slidably mounted on the top of the mounting platform 1, the slide bars 2 form protrusions at both ends of the bottom of the main body in a manner that they can contact the side walls of the mounting platform 1. The advantage of this arrangement is that the protrusions contact the two sides of the mounting platform 1, so that the slide bars 2 can slide smoothly on the top of the mounting platform 1, and a rubber anti-skid pad is provided at the central position of the top of the mounting platform 1. The advantage of this arrangement is that when the stamping mold is hoisted above the mounting platform 1, it plays a buffering and protective role on the mold. A pair of grooves 7 for accommodating the rubber anti-skid pads are provided at the bottom of the slide bars 2. A pair of first bolts 3 are slidably installed, a limiting hole 8 for the first bolt 3 to slide is opened on the top of the slide bar 2, a penetrating sliding hole is opened on the side wall of the slide bar 2, the bottom of the first bolt 3 extends into the sliding hole, and a slider 6 is fixedly installed, a pressing block 5 is sleeved on the first bolt 3, and the pressing block 5 and the first bolt 3 are key-connected, and a plurality of limiting edges 9 distributed in a circumferential manner are fixedly installed on the side wall of the first bolt 3, a positioning hole 10 adapted to the limiting edge 9 is opened on the top of the pressing block 5, and the pressing block 5 is key-connected with the first bolt 3 through the positioning hole 10 and the limiting edge 9, and an elastic member is provided between the pressing block 5 and the slide bar 2, and the elastic member is a spring sleeved on the first bolt 3. The two ends of the spring are in contact with the pressure block 5 and the slide bar 2 respectively. A second bolt 4 is provided at the central position of the slide bar 2 so that the nut on the second bolt 4 can be locked to drive a pair of pressure blocks 5 to press the mold edge at the same time. When installing the mold, the present application first places the mold on the top of the mounting table 1, then slides the slide bar 2 on the top of the mounting table 1 until the pressure block 5 is above the mold edge, and then adjusts the angle of the pressure block 5 according to the shape of the mold. When adjusting the angle, the pressure block 5 is pressed to compress the spring and move downward on the first bolt 3. After the positioning hole 10 is disengaged from the limiting edge 9, the angle of the pressure block 5 can be rotated to adjust the pressure block 5. After adjusting to a suitable angle, the pressure block 5 is released, and the spring releases its own elastic potential energy. That is, the positioning hole 10 is driven to engage with the limiting edge 9 to limit the angle of the pressure block 5. Then the operator uses a tool to screw the nut on the second bolt 4, and through the locking nut, the slide bar 2 drives a pair of pressure blocks 5 to press the mold at the same time through the slide hole to complete the fixation of the mold. The present application forms a mold fastener on the top of the mounting table 1 through the cooperation of the slide bar 2, the first bolt 3, the pressure block 5 and the spring. Compared with the conventional mold fastener pressure plate, the present application limits the angle of the pressure block 5 and is suitable for various types of molds. Moreover, by screwing the nut on the second bolt 4, a pair of pressure blocks 5 can be driven to press and fix the mold at the same time. The structure is simple and the operation is convenient, which effectively brings convenience to the assembly of the mold.
