The invention discloses a novel numerical control silicon steel sheet transverse shearing line device. The novel numerical control silicon steel sheet transverse shearing line device comprises a control center, a discharging device and a feeding channel. The feeding channel is sequentially provided with a front feeding device, a first punching device, a V-shaped opening shearing device, a second punching device, a rear feeding device, a swing shearing device and a discharging table. A material collecting device is arranged behind the discharging table. The material collecting device comprises a magnetic conveying belt and a sheet stacking table. The numerical control silicon steel sheet transverse shearing line device has the beneficial effects that the front feeding device and the rear feeding device are arranged, waste of sheets is reduced, and the shearing precision is improved; twisting and bulging of silicon steel sheets are avoided, and high-speed conveying of the silicon steel sheets is achieved; the first punching device and the second punching device are symmetrically distributed on the front side and the rear side of the V-shaped opening shearing device, one-step punching is achieved, time is saved, and the production efficiency is improved; and according to the material collecting device, the magnetic conveying belt is matched with the sheet stacking table, shorn silicon steel sheets are automatically stacked in order, operation of workers is reduced, human resources are saved, and efficiency is improved.

The invention discloses a welding jig for a petroleum filter pipe sleeve hanger. The welding jig comprises a V-shaped push block, a hanging arm fixing block, a jig body, a push block guide pillar and a guide pillar positioning block, wherein one end of the V-shaped push block is provided with a V-shaped opening made of tooth-shaped metal plate for fixing the hanger while the other end of the V-shaped push block is connected to the guide pillar positioning block through the push block guide pillar; the hanging arm fixing block is provided with a groove for containing the hanging arm of the hanger; the hanging arm fixing block, the V-shaped push block and the guide pillar positioning block are sequentially arranged on the jig body; the jig body is arranged on the welding arm of a spot-welder. The welding jig provided by the invention has the advantages of novel structure, rapid machining speed, high welding quality and capable of adapting to different types of welding parts.

Provided is a rotational-speed-controlling variable piston pump with which it is possible to satisfactorily avoid abnormal pressures in the bore chamber of a cylinder block with a simple configuration, without causing loss of pump efficiency or increases in cost. The present invention provides a rotational-speed-controlling variable piston pump in which pistons move back and forth within a bore at a stroke suited to the angle of inclination of a swash plate along with the rotation of a cylinder block, whereby hydraulic oil is drawn into a bore chamber from an intake oil passage formed in a casing, via an intake port of a port plate against which the cylinder block slides, and the hydraulic oil is discharged to a discharge oil passage formed in the casing, via a discharge port of the port plate; wherein an abnormal-pressure-avoiding oil pressure circuit, which releases the hydraulic oil in the bore chamber out of the bore chamber when the pressure in the bore chamber positioned between the intake port and the discharge port of the port plate exceeds a predetermined pressure, is provided as being incorporated in the same unit structure within the same casing.

The present invention relates to the technical field of cable connection, in particular to a cable connection mechanism for data storage cabinets, including a connection housing, two ends of the connection housing are provided with guide wire through holes, the connection housing Both ends are connected with fixing sleeves, and both ends of the two fixing sleeves are equipped with cable fixing sleeves, and the cable fixing sleeves are fixedly connected with wiring sleeves, and the connecting housing, fixing sleeve , the cable fixing sleeve and the wiring sleeve wrap the thermoplastic pipe on the surface after the cable is connected, the inside of the connecting shell is fixedly connected with a contact element, and the two first limit bolts are arranged in reverse mirror image, The invention enables the copper wire to be firmly fixed on the contact element, replaces the traditional work process of winding the copper wire on the contact element, simplifies the cable connection process, reduces labor input, and avoids the hidden danger of worker injury At the same time, the connection efficiency between the cable and the contact element is improved.

A shock-absorbing comfortable sole comprises an outsole in contact with the ground and a midsole fixed on the upper surface of the outsole. The midsole comprises an upper layer and a lower layer. One or a plurality of through holes penetrating through the midsole in the thickness direction are respectively reserved on a heel, a rear sole and / or a front sole of the upper midsole. Projections corresponding to the through holes on the upper midsole are arranged on the upper surface of the lower midsole. The projections on the lower midsole are connected with the through holes on the upper midsole respectively in an embedded manner. Bottom grains protruding the lower surface of the outsole and corresponding to the projections on the lower midsole in position are arranged on the lower surface of the outsole. The upper midsole is hard, the lower midsole is soft, and when the surface of the upper midsole is stepped by a foot in walking, the upper surfaces of the soft projections are recessed highly and the upper surface of the hard upper midsole is recessed lowly, so that the upper surface of the upper midsole is flat or slightly uneven alternately, a foot sole of a wearer can be massaged, walking fatigue can be relieved, and the effect is evident.

The invention discloses an automatic wood pallet nailing machine. The automatic wood pallet nailing machine comprises a rack, a moving trolley, a clamp and a plurality of fastener devices. Guide rails are arranged on the two sides of the rack. Sliding wheels are arranged at the bottom of the moving trolley and are in sliding connection to the guide rails on the two sides of the rack. The clamp is installed on the rack and used for positioning a wood pallet material to be machined. The fastener devices are installed on the moving trolley in the transverse direction and used for nailing the wood pallet material to be machined. According to the automatic wood pallet nailing machine, manual machining is replaced by mechanical automation machining, the production efficiency is greatly improved, the machining quality is good, the using stability of products is good, the service life is long, meanwhile, the hidden danger of worker injuries prone to being caused in the machining process is avoided, the labor intensity of workers is relieved, and the production cost is reduced.
