The invention discloses a multi-station jumping riveting mechanism, a riveting machine and a chain assembling processing assembly line. The multi-station jumping riveting mechanism, the riveting machine and the chain assembling processing assembly line comprises an upper die mechanism and a lower die mechanism arranged at the lower end of the upper die mechanism, a riveting mechanism is arranged between the upper die mechanism and the lower die mechanism, and a chain jumping mechanism is arranged middle of the jumping riveting mechanism; the jumping riveting mechanism comprises a height adjusting rod of an exposed head pressing block, an upper exposure head pressing block arranged at the lower end of the height adjusting rod of the exposed head pressing block and fixedly connected with theheight adjusting rod of the exposed head pressing block, and a lower exposure pressing block arranged at the lower end of the upper pressing block. According to multi-station jumping riveting mechanism, the riveting machine and the chain assembling processing assembly line, a novel shaping mechanism is arranged and is used for chains and riveting heads, the outer section and outer width of chainsare shaped through pressure coordination of the upper pressing block and the lower pressing block, so that the pressure load of a chain assembling machine is reduced, assembling precision of the chain assembling machine is further improved, and shaping precision of the outer section and the outer width is improved; and the multi-station jumping riveting mechanism, the riveting machine and the chain assembling processing assembly line has the advantages that the operation difficulty is reduced, the working efficiency is improved, and cost is reduced.

The invention relates to a light-cured 3D printing material and its preparation method and application. The photocurable 3D printing material includes the following raw material components in parts by weight: 20-80 parts of photocurable resin, 10-60 parts of photocurable reactive diluent, 1-10 parts of photoinitiator, and 0.1-20 parts of thixotropic agent part, 0.1-5 parts of auxiliary agent; wherein, the thixotropic agent is at least one of attapulgite, montmorillonite, bentonite, fumed silica, polyamide wax, mica powder; the photocurable resin is At least one of aliphatic polyurethane and alicyclic epoxy resin. The light-curing 3D printing material has excellent thixotropy and can be applied to the FDM nozzle printing process. Compared with SLA, it can effectively reduce the production cost of 3D printing products, and has fast molding speed and high precision, and can perform complex contours or large-scale 3D printing. The production of products.

The invention relates to a steel pipe shaping device, comprising: a fixed frame, the fixed frame has a first support rod and a second support rod respectively arranged on two sides, and a cross bar straddles the first support rod and the second support rod One end of the two support rods is far away from the place; a first side pressure seat is arranged on the first support rod, a second side pressure seat is arranged on the second support rod; an upper pressure seat is arranged on the cross bar; a The first side pressing block is inserted in the first side pressing seat, a second side pressing block is inserted in the second side pressing seat, and an upper pressing block is inserted in the upper pressing seat; the first side The pressing block, the second side pressing block and the upper pressing block respectively expand and contract with respect to the first side pressing seat, the second side pressing seat and the upper pressing seat so as to shape the steel pipe to be shaped. Thereby, the present invention reduces manual workload, increases work efficiency and improves product shaping precision through the arrangement of the novel steel pipe shaping device.

The invention relates to a laser shaping pulse acquisition device and acquisition method, belonging to the technical field of laser equipment. The acquisition device includes a seed source, a first optical modulator, at least one The amplifier, at least one acousto-optic switch, and the second optical modulator also include an arbitrary waveform generator connected to the first optical modulator and the second optical modulator through radio frequency lines, and the present invention adopts electro-optical modulation technology to cascade two-stage optical In the modulator mode, the time window of the optical modulator is precisely regulated by the electrical pulse generated by the arbitrary waveform generator. At the same time, the amplifier and the acousto-optic switch are used together to control the spontaneous emission noise generated by the amplifier based on the particle number inversion. Preliminary filtering, combined with the use of multi-stage amplifiers to reasonably control the energy flow distribution, significantly improves the shaping accuracy, contrast and signal-to-noise ratio of the output laser shaping pulse.

The invention discloses shaping auxiliary device for tyre shaping vulcanizer. The shaping auxiliary device comprises that left and right handing mechanisms arranged on a vulcanizing chamber. The left handing mechanism is arranged on a left tilting mechanism which transferred from left front vulcanizing chamber and the right handing mechanism is arranged on a right tilting mechanism which transferred from the right front vulcanizing chamber. Or the left handing mechanism is arranged on the left tilting mechanism which transferred from the left rear vulcanizing chamber and the right handing mechanism is arranged on the right tilting mechanism which transferred from the right rear vulcanizing chamber. The left and right tilting mechanisms are arranged on left and right foundation frameworks on both sides of the vulcanizing chamber, respectively. Tire billets are located on the back vulcanizing chamber. Tilting mechanism synchronous motion support the opposite left and right handing mechanisms on tire billets and set it in middle. The shaping auxiliary device efficiently improves accuracy of tyre shaping press and tire quality and reduce waste defective rate, which enhance the economic benefits of engineering tire and giant tire.
