The invention provides a special-shaped pipe welding and clamping device, which belongs to the technical field of tooling fixtures and includes a frame, a driving device, a positioning clamping device and an auxiliary device. The front end of the frame is slidably provided with a driving device, and the middle part of A positioning and clamping device is provided, and an auxiliary device is provided at the tail of the frame. The driving device is connected to the positioning and clamping device in transmission, and the driving device is connected to the auxiliary device in transmission. When it is in use, the positioning and clamping device fixes the workpiece, the auxiliary device assists in fixing the workpiece, and performs welding on one side of the workpiece. After the welding is completed, the driving device drives the positioning and clamping device to change the posture of the workpiece, thereby performing welding on the other side of the workpiece. Welding, and then complete the welding process of the special-shaped workpiece, the invention has novel design and reliable function, realizes the integrated welding of the special-shaped workpiece, prevents the deviation of the welding part, and solves the problem of the inability to guarantee the precision of the special-shaped pipe in the welding process in the prior art. The problem of high defective rate.

The invention discloses a puncture-resistant vacuum insulation board. The puncture-resistant vacuum insulation board comprises a puncture-resistant layer, a vacuum encapsulation layer and a core material inside the vacuum encapsulation layer. The puncture-resistant layer is made of polyurethane foam materials, bonds to the surface of the vacuum encapsulation layer, and is obtained through a foaming reaction of polyether polyol or polyester polyol and polyisocyanates. Meanwhile, the invention further discloses a manufacturing method of the vacuum insulation board. The obtained vacuum insulation board has good puncture resistance, largely reduces the high defective rate caused by puncture, scrapping and rubbing when the vacuum insulation board is conveyed and used, lowers the construction difficulty, has excellent insulation property, and is suitable for being applied to and popularized in various heat-preservation places.

The invention discloses a hob machine for processing communication electronic materials, which includes a workbench and a hob. The upper end of the workbench is symmetrically and fixedly connected with two fixing plates, and the side walls of the two fixing plates are connected by rotation together. There are winding rollers, and an adjustment mechanism is installed on the workbench. The adjustment mechanism includes a chute set on the upper end of the workbench. The inner wall of the chute is symmetrically slidably connected with two sliders, and the upper ends of the two sliders are fixed. Two vertical rods are connected, the side walls of the two vertical rods are rotatably connected to two connecting rods, the other ends of the two connecting rods are jointly rotatable and connected to a rotating rod, and the side walls of the rotating rods are rotatably connected to an adjustment roller; In the present invention, by driving the second motor to rotate in the forward direction, the adjustment roller is driven to move, and then the electronic materials are compressed or loosened, so as to facilitate the adjustment of the tension of different electronic materials and avoid the electronic materials from being too tight during the processing process. Stretch or too loose will increase the defective rate of processing.

The invention relates to an intelligent heat treatment industrial furnace of a safety shoe antisquashy steel wrapping head, which is provided with a heating chamber, a quenching chamber and a tempering chamber, wherein heating resistance threads are arranged in the heating chamber and the tempering chamber, and a quenching cooling cylinder is arranged in the quenching chamber. Tracks are arrangedin the heating chamber, the quenching chamber and the tempering chamber, are provided with track ascending and descending hooks, and are driven by a motor. A pumping channel is arranged between the heating chamber and the tempering chamber. An output interface of an industrial personal computer is respectively connected with a thermocouple temperature sensor, the heating resistance thread, the track ascending and descending hook, a pendant track and an exhaust fan via digital-analog conversion A / D. The technology for heat treatment of different steel is pre-stored in the industrial personal computer, the heat treatment control parameters can be set automatically, and the output interface of the industrial personal computer is respectively connected with parts needing control via digital-analog conversion, so the heat treatment process can be precise, and the quality of the wrapping head is ensured. The pumping channel between the heating chamber and the tempering chamber can guide hotair in the heating chamber into the tempering chamber for preheating, reduces energy consumption and increases the production efficiency.

The invention relates to a production technique for pans. The production technique at least includes the following steps that: (1) a pan body is prepared, and a positioning pin is spot-welded on the bottom of the pan body; (2) the inner surface of the pan body going through step 1 receives special surface treatment; (3) an inner composite bottom plate with a positioning hole is prepared, and the position and size of the positioning hole correspond to the position and size of the positioning pin; (4) an outer composite bottom plate is prepared and assembled on the inner composite bottom plate prepared in step 3 to form an inner-outer composite bottom plate assembly; (5) a repeated hot forging method is adopted to combine the pan body going through step 2 and the inner-outer composite bottom plate assembly obtained in step 4 together. The invention meets the requirement of the production technique on positioning, and also prevents the inner special-treated layer of the pan body from being damaged. The invention has the advantages of simple process and low cost, and therefore is more suitable for production in batches, and the invention thoroughly solves the problem of high defectiveproduct rate in the prior art, and increases the product quality.
