Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of perforating equipment, and particularly relates to a polyurethane block perforating device. BACKGROUND

[0002] At present, polyurethane is widely used in the internal reinforcing structure of a cabin cover, and serves as the main reinforcing structure of the cabin cover for resisting wind load, snow load and other loads. The wettability of the polyurethane block is very critical in the process of vacuum glue injection of the cabin cover composite material. Once the wettability is poor, the overall strength is greatly affected. Before wettability, the polyurethane block needs to be manually cut into a trapezoidal structure, and then manually perforated by using a drill and other tools. The manual perforation operation is prone to cause uneven distribution of hole positions on the polyurethane block, and different sizes and specifications, which finally leads to irregular wettability of the holes on the polyurethane block, and easily forms surrounding and dry areas, thereby affecting the overall strength of the internal reinforcing structure of the cabin cover. SUMMARY

[0003] In view of the above technical deficiencies, the purpose of the present application is to provide a polyurethane block perforating device, which has the advantages of uniformity and efficiency of perforation.

[0004] To solve the above technical problems, the present application adopts the following technical scheme: the present application provides a polyurethane block perforating device, which comprises a rack, a cylinder mounting seat and a base are sequentially and spacedly arranged on the rack from top to bottom, a plurality of cylinders are arranged on the cylinder mounting seat, a tool pressing plate frame is arranged on the piston rod of the cylinder, a plurality of needle assemblies are movably arranged in the tool pressing plate frame, a pressing plate is movably arranged on the base through a lifting assembly, a plurality of circular hole groups corresponding to the positions of the needle assemblies are arranged on the pressing plate, material ports are arranged on the opposite side walls of the rack, and the pressing plate is located between the two material ports.

[0005] Preferably, the tool pressing plate frame comprises a rectangular frame arranged on the piston rod of the cylinder, the opposite side walls of the rectangular frame are open, a plurality of sliding seat grooves are parallelly and spacedly arranged in the rectangular frame, a sliding seat is slidably arranged in the sliding seat groove, the needle assembly is arranged on the bottom surface of the sliding seat, and a locking assembly movably connected with the sliding seat is further arranged on the opposite side walls of the rectangular frame, so as to facilitate the perforation of the polyurethane block by the cylinder driving the needle assembly.

[0006] Preferably, the locking assembly includes a left fixing block and a right fixing block spaced apart on the side wall of the rectangular frame opening. A locking shaft is movably disposed between the left and right fixing blocks. The length direction of the locking shaft axis is perpendicular to the length direction of the slide groove. Multiple stops corresponding to the slide are movably sleeved on the outside of the locking shaft. Multiple locking shaft through holes with diameters adapted to the locking shaft are spaced apart along the length direction on the slide. This allows the locking shaft to pass through the corresponding locking shaft through holes on the slide after the position of the slide is adjusted by sliding within the slide groove, thereby fixing the position of the slide.

[0007] Preferably, guide rods are provided on the opposite side walls of the slide groove, and guide grooves corresponding to the guide rods are provided on the opposite side walls of the slide. The guide rods are slidably disposed in the guide grooves at their respective positions. When the position of the slide is adjusted by sliding in the slide groove, the guide rods can slide in the guide grooves at their respective positions, which helps to maintain the accurate position of the slide and thus improves the perforation quality of the polyurethane block.

[0008] Preferably, the needle assembly includes a plurality of connecting holes spaced apart on the bottom surface of the slide, and a needle is movably disposed in the connecting holes, so as to facilitate the installation of the needle in the connecting holes or the removal of the needle from the connecting holes as needed.

[0009] Preferably, the circular hole group includes a plurality of circular through holes distributed in a matrix on the pressure plate, and the number of circular through holes is greater than the number of needles, so that when the polyurethane block is pierced, the needles can penetrate into the circular through holes after piercing the polyurethane block, allowing the residue of the polyurethane block to be discharged through the circular through holes.

[0010] Preferably, the lifting assembly includes threaded rods vertically penetrating through the base at opposite ends. The bottom surfaces of the opposite ends of the pressure plate are rotatably connected to the two threaded rods respectively. Multiple lifting blocks are provided on the other two opposite side walls of the pressure plate. Multiple lifting block slots corresponding to the lifting blocks are vertically provided on the two opposite inner walls of the material inlet. The lifting blocks are slidably disposed in the corresponding lifting block slots, which facilitates the vertical position adjustment of the pressure plate by rotating and adjusting the threaded rods according to the different heights of the polyurethane blocks, thereby facilitating the placement of polyurethane blocks of different heights.

[0011] Preferably, two limiting blocks are symmetrically arranged on the two opposing inner walls of the material inlet. The limiting blocks are located above the lifting block groove. The end of the limiting block away from the inner wall of the material inlet is provided with an inclined surface, which faces the top surface of the pressure plate. This facilitates the placement of the polyurethane block between the pressure plate and the limiting block for clamping and fixing, thereby facilitating the stable position of the polyurethane block during the piercing operation.

[0012] Preferably, a support rod slot is further arranged on the base, a horizontal crossbar is arranged in the support rod slot, a plurality of rod sleeves are slidably arranged on the crossbar, support rods are threadedly connected to the outer circumferential walls of the rod sleeves, and the ends of the support rods away from the rod sleeves abut against the bottom surface of the pressing plate. Before the polyurethane block is perforated, the ends of the support rods away from the rod sleeves abut against the bottom surface of the pressing plate, thereby improving the positional stability of the pressing plate.

[0013] The polyurethane block perforating device has the following beneficial effects: 1. The cylinder is used as the driving device for perforation, and the piercing needle is driven to complete the perforation operation, thereby keeping the hole size consistent after perforation and improving the subsequent infiltration effect.

[0014] 2. The two end sidewalls of the rack are both provided with a material inlet, so that the polyurethane block can be fed and discharged before perforation, thereby improving the convenience and efficiency of the operation.

[0015] 3. When the polyurethane block is perforated, the piercing needle can penetrate into the circular through hole after the polyurethane block is pierced, so that the residues of the polyurethane block are discharged through the circular through hole, and the residues are conveniently collected.

[0016] 4. The position of the sliding seat in the sliding seat slot can be adjusted according to the different lengths of the polyurethane block, and the position of the sliding seat is fixed by the locking assembly, so that the piercing needle assembly on the bottom surface of the sliding seat at different positions can complete perforation at different positions on the polyurethane block, thereby improving the diversity of the perforation position.
